What to do when we lose the fight for our country? Emigration is one of the solutions historically tried by Poles. Political emigration is a way out with the intention of returning — to a free country again. Returning with weapons in hand, with ready ideas for reform and contacts made in the world that are helpful to the country, and finally with money earned in other countries and under different conditions that will be useful as an investment in one's own homeland.
This is an experience practiced in our history since the 18th century, when the Republic of Poland, subjected to external control, lost its independence and there were people who decided to fight for this independence — but they lost.
The first great uprising was the Dzików Confederation, almost completely forgotten today, established in 1734 in Dzików, but which spread armed resistance to a significant part of the Polish-Lithuanian Commonwealth. It was a statement against the open military intervention of Russia, which imposed a king on Poland in 1733 against the will of its citizens. Citizens chose Stanisław Leszczyński, and the Russian Tsarina — Augustus III Sas.
It was then, when Russian troops entered, that a young Piarist priest, Stanisław Konarski, re-popularized the concept of independence in his Confidential Letters from the Interregnum. He served the Confederates until 1736, seeking diplomatic assistance from France. When this failed, he returned from emigration to the country: with his head full of ideas on how to raise his homeland from decline. From his stay in the countries of Western Europe, he brought new concepts of education — and according to them, he prepared the first school for the renewal of the Polish-Lithuanian Commonwealth, Collegium Nobilium in Warsaw, and reformed the entire network of Piarist education, combining the study of the modern world with education for civic duty in a modern system. To contribute to the convalescent reform of political institutions, he prepared the most important work of Polish political journalism of the 18th century: On an effective Council Method, driving into Sarmatian heads the need to reject the liberum veto, which is manipulated by our neighbors to enslave our country. Without Konarski, there would be no Constitution of May 3.
Earlier, however, due to another armed intervention by Russia in Warsaw itself — the kidnapping of senators and envoys on Catherine's orders and the imposition of formal Russian "protection" on the Commonwealth — another great uprising broke out: the Bar Confederation, which lasted four years. It lost against the violence of a neighboring empire. However, it also retained in the actions of one of her emigrant MPs an example of what we can and should strive for when fate throws us out of an enslaved country.
In order to prepare the justification for the partition of Poland, Catherine II and Frederick II of Prussia created an extremely effective propaganda image of the Polish-Lithuanian Commonwealth as a black hole on the map of the European Enlightenment, a den of ignorance and superstition that only Prussian and Moscow bayonets could sort out. Such a picture was sketched with the money of both partitioners by the first writers of enlightened Europe: Voltaire, Diderot, Baron Grimm.
The response to the actions of the confederate envoy, and then the emigrant — the great Lithuanian chef, Michał Wielhorski, followed. He did not obtain diplomatic help from Paris, but understanding how important the fight for the country's image in international public opinion was, he established contact with its then co-creators: Gabriel Mably and Jean-Jacques Rousseau. Both famous philosophers, under his influence and based on the materials he provided, wrote works that will create an important counter-current to the "black legend" of Poland. In particular, Rousseau's book, Notes on the Polish Government, will become a lasting point of reference on the intellectual map of Europe, in which Sarmatian freedom is not condemned as "ignorance and anarchy", but appreciated as a manifestation of the republican spirit. And for Poles it will become yet another signpost for the future: "If you can't prevent your neighbors from swallowing you, make sure they can never digest you." Culture, national culture, is the most important thing — this was announced by Rousseau, persuaded by the Bar emigrants.
And we know from the history of the 19th century, after the Polish-Lithuanian Commonwealth was erased from the map by the three empires, that this advice would prove to be beneficial in the long run, and emigration will play the most important role in its fulfillment.
Of course, we also know that subsequent waves of emigration, immediately after the fall of the Constitution of May 3 as a result of the invasion of Catherine's army in 1792, and then, after the final partition of Poland in 1795, were primarily concerned with political and organizational preparations for the resumption of armed struggle for independence and seeking help for it in the West.
The result of the first of these emigrations (concentrated in Dresden and revolutionary Paris) was the preparation of the Kościuszko Uprising.
The second emigration, after the defeat of the insurrection, will bring as its most important fruit the Dąbrowski Legions — those that finally "came from Italy to Poland" with Napoleon in 1806. This allowed for the reconstruction of the nucleus of the Polish statehood: the Duchy of Warsaw.
Although Napoleon lost the next confrontation with Russia and the matter of the Duchy was buried, the effort, symbolized by the Legions created by the emigration, was not entirely wasted. At the Congress of Vienna after the Napoleonic Wars, the name of the Kingdom of Poland was restored, although only as a small area under the rule of Tsar Alexander I. For the next 15 years (1815–1830), Poles again had a substitute for their statehood. Valuable, but insufficient for those who wanted independence and the integrity of the Republic of Poland. So another uprising broke out, called the November Uprising. And it was defeated by Tsar Nicholas and the most powerful army in the world at that time. The defeat of the uprising triggered the largest ever wave of emigration.
Since 1831, the division: country — emigration, and certainly of Polish culture, has appeared in the history of Poland and it was repeatedly renewed until the second half of the 20th century. Country — this is the area of Poland, which is not sovereign and therefore cannot freely develop its culture and political debate. Emigration replaces the country in these functions. Of course, we are talking about political emigration, not mass economic emigration, which would become an important social phenomenon only at the end of the 19th century. Emigration after 1831 included just over 10,000 people. Most of them, about 6,000, settled in France. About 700 lived in Great Britain, and several hundred also in Belgium. Smaller groups — in Greece, Turkey, Italian and German countries, as well as in Spain and Algeria, colonized by France.
Initially, only a few dozen insurgents reached the United States, with the support of the American-Polish Committee and led by James F. Cooper (author of The Last of the Mohicans). The specific quality of this emigration was more important than the number. It was composed largely of officers coming from the nobility and intelligentsia, volunteers of the insurgent army, participants of the political life of the Kingdom of Poland. They were almost exclusively men. Most of them remained bachelors. A group of about 200 Polish women emigrated; mixed marriages, with French women, were rare. Many Polish emigrants did not seek stability abroad, but lived with the thought, even obsession, of returning to the country: returning with weapons in their hands, to the liberated Poland.
While we can talk about a strong patriotic mobilization of a large part of the Polish social elite, certainly during the November Uprising, emigration after the uprising was characterized by almost feverish mobilization. It also had special intellectual capabilities to perpetuate this fever, spread it, and create an institution and a specific political culture out of it. It was an emigration of not only literate people, almost 100 percent of them, but also in a very large part of educated people — from the universities of Warsaw, Vilnius, and the Krzemieniec High School.
Already in France, out of 6,000 emigrants, 1,117 people have pursued higher education (most often in medicine and engineering). Further education — it was assumed — would be useful in the reborn Republic of Poland. In such a community, it became possible to publish nearly 100 different magazines (until 1848) and over 1,700 books and political pamphlets, which was helped by the fact that nearly 200 emigrants took up work as printers, lithographers and bookbinders.
Poles have not yet been able to create their own university in exile, but they have established several other, permanent institutions of culture, education and science. These include: The Literary Society, founded in Paris in 1832 (it had a Science Department and a Statistical Department in its structure; from 1854 it was called the Historical and Literary Society); since 1838 Polish Library has been operating in the heart of Paris, on the Island of St. Louis; from 1842, there was also a Polish secondary school in Paris for over 100 years.
However, there was something else that escapes statistical calculations: the concentration of the greatest talents in this emigration circle, and in the case of a few people, one could say, the greatest geniuses in the history of Polish culture. These were Adam Mickiewicz, Juliusz Słowacki, Zygmunt Krasiński — three poets who were recognized in this history as the three "national bards". They will be joined a little later by the "fourth bard" — Cyprian Kamil Norwid. They were accompanied in music by Fryderyk Chopin. Apart from them, there are other talented poets, publicists and historians — co-creators and popularizers of new symbols and myths in the national imagination. They, above all Chopin, will undoubtedly create the most perfect "soft power" instrument for Polish independence, especially at a time when Poland, deprived of a state, had no "hard power" at its disposal.
It is worth recalling, however, that such a role was also played by the successes of other Polish emigrants, of course on a smaller scale. Three examples can be given: Ignacy Domeyko, Paweł Edmund Strzelecki and Antoni Norbert Patek. They can be treated as evidence of a specific "globalization" of Polishness, which emigration fostered.
Domeyko (1802–1889), one of Mickiewicz's friends from the University of Vilnius, where he studied differential calculus, decided to take up new studies in exile, at the Mining School (École de Mines) in Paris. He used the knowledge he gained by going all the way to Chile. There he organized the foundations of modern mineralogy and the mining industry, and also reformed the capital's university in Santiago, serving as its rector for 16 years. Next to the next generation emigrant, Ernest Malinowski (1818–1899 — he emigrated after the November Uprising as a boy, together with his father), the builder of the Trans-Andean railway in Peru and Ecuador, Domeyko became a hallmark for Poles in Latin America, just as previously Kościuszko and Pulaski had for Poles in North America. However, the hallmark was not the saber, but a university diploma and engineering achievements.
Paweł Edmund Strzelecki (1797–1873) played a similar role for Australia. Strzelecki, originally from Poznań, left the country before 1830 due to unhappy love and his great passion for traveling. After touring Canada, the United States, Mexico, South America, Hawaii and Tahiti, he reached New Zealand and Australia in 1839. In Australia, he explored mineral deposits in the Gippsland region (he discovered gold deposits there), and in 1840 he explored and measured the highest peak of the continent in the Australian Alps: he named it Mount Kosciuszko (2,228 m above sea level). Although he was not a political emigrant in the strict sense of the word, he willingly financially supported the activities of the Literary Society of Friends of Poland in Great Britain.
Antoni Norbert Patek (1812–1877) was an 18-year-old who won the Golden Cross of the Order of Virtuti Militari for his service in the cavalry of the November Uprising. In exile, he settled in Switzerland. In Geneva, after years of practice, he founded his own watch factory, which used the most modern invention: head winding. In 1845, in partnership with the French inventor Adrian Philippe, he created a new watchmaking company that introduced watches with a separate second hand to the market. Patek Philippe gained a reputation during his lifetime, producing some of the world's first wristwatches. Today, it is the most exclusive watch brand in the world.
Did these careers result in anything for Poland? Results? Thousands of emigrants, of course, did not have any careers. Most lived in daily poverty, on small government benefits (in France) and odd jobs paid until 1856. The main diversion was political activity. Thanks to this activity, emigration became a laboratory of organizational forms of modern political life. And yet, the examples given here of action that go beyond involvement in "damning quarrels", i.e. political life, are not a form of departure from Poland, but a service to its culture, its good name, pride in this name — through individual scientific and technical achievements, artistic – they deserve to be reminded.
Of course, they do not end with the times of the Great Emigration, but they find further confirmation — from Maria Skłodowska to Tadeusz Sendzimir and Zbigniew Brzeziński. Poland is on the map. But it's good that we have these heroes.

The Zwicky Transient Facility (ZTF) is a new optical time-domain survey that uses the Palomar 48 inch Schmidt telescope. A custom-built wide-field camera provides a 47 deg(2) field of view and 8 s readout time, yielding more than an order of magnitude improvement in survey speed relative to its predecessor survey, the Palomar Transient Factory. We describe the design and implementation of the camera and observing system. The ZTF data system at the Infrared Processing and Analysis Center provides near-real-time reduction to identify moving and varying objects. We outline the analysis pipelines, data products, and associated archive. Finally, we present on-sky performance analysis and first scientific results from commissioning and the early survey. ZTF's public alert stream will serve as a useful precursor for that of the Large Synoptic Survey Telescope.
We present ground-based and Swift observations of iPTF16fnl, a likely tidal disruption event (TDE) discovered by the intermediate Palomar Transient Factory (iPTF) survey at 66.6 Mpc. The light curve of the object peaked at an absolute mag M-g = -17.2. The maximum bolometric luminosity (from optical and UV) was L-p similar or equal to (1.0 +/- 0.15) x 10(43) erg s(-1), an order of magnitude fainter than any other optical TDE discovered so far. The luminosity in the first 60 days is consistent with an exponential decay, with L proportional to e(-(t-t0)/T), where t(0) = 57631.0 (MJD) and tau similar or equal to 15 days. The X-ray shows a marginal detection at L-X = 2.4(-1.1)(1.9) x 10(39) erg s(-1) (Swift X-ray Telescope). No radio counterpart was detected down to 3s, providing upper limits for monochromatic radio luminosities of nu L-nu < 2.3 x 10(36) erg s(-1) and nLn < 1.7 x 10(37) erg s(-1) (Very Large Array, 6.1 and 22 GHz). The blackbody temperature, obtained from combined Swift UV and optical photometry, shows a constant value of 19,000 K. The transient spectrum at peak is characterized by broad He II and Ha emission lines, with FWHMs of about 14,000 km s(-1) and 10,000 km s(-1), respectively. He. I lines are also detected at lambda lambda 5875 and 6678. The spectrum of the host is dominated by strong Balmer absorption lines, which are consistent with a post-starburst (E+A) galaxy with an age of similar to 650 Myr and solar metallicity. The characteristics of iPTF16fnl make it an outlier on both luminosity and decay timescales, as compared to other optically selected TDEs. The discovery of such a faint optical event suggests a higher rate of tidal disruptions, as low-luminosity events may have gone unnoticed in previous searches.
Obtaining spectroscopic observations of the progenitors of core-collapse supernovae is often unfeasible, due to an inherent lack of knowledge as to what stars experience supernovae and when they will explode. In this Letter we present photometric and spectroscopic observations of the progenitor activity of SN 2023fyq before the He-rich progenitor explodes as a Type Ibn supernova. The progenitor of SN 2023fyq shows an exponential rise in flux prior to core collapse. Complex He I emission line features are observed in the progenitor spectra, with a P Cygni-like profile, as well as an evolving broad base with velocities of the order of 10 000 km s−1. The luminosity and evolution of SN 2023fyq is consistent with a Type Ibn, reaching a peak r-band magnitude of −18.8 mag, although there is some uncertainty regarding the distance to the host, NGC 4388, which is located in the Virgo cluster. We present additional evidence of asymmetric He-rich material being present both prior to and after the explosion of SN 2023fyq, which suggests that this material survived the ejecta interaction. Broad [O I], C I, and the Ca II triplet lines are observed at late phases, confirming that SN 2023fyq was a genuine supernova, rather than a non-terminal interacting transient. SN 2023fyq provides insight into the final moments of a massive star's life, demonstrating that the progenitor is likely highly unstable before core collapse.
During the Zwicky Transient Facility (ZTF) Phase I operations, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than 3 yr, constituting the largest sample from a single survey. This paper (Paper I) presents the data, including the optical/UV light curves and classification spectra, while Paper II in this series will focus on the detailed analysis of the light curves and modeling. Our photometry is primarily taken by ZTF in the g, r, and i bands, and with additional data from other ground-based facilities and Swift. The events of our sample cover a redshift range of z = 0.06 − 0.67, with a median and 1σ error (16% and 84% percentiles) of zmed=0.265. The peak luminosity covers −22.8 mag ≤ Mg,peak ≤ −19.8 mag, with a median value of -21.48. The light curves evolve slowly with a mean rest-frame rise time of trise = 41.9 ± 17.8 days. The luminosity and timescale distributions suggest that low-luminosity SLSNe-I with a peak luminosity ∼−20 mag or extremely fast-rising events (<10 days) exist, but are rare. We confirm previous findings that slowly rising SLSNe-I also tend to fade slowly. The rest-frame color and temperature evolution show large scatters, suggesting that the SLSN-I population may have diverse spectral energy distributions. The peak rest-frame color shows a moderate correlation with the peak absolute magnitude, i.e., brighter SLSNe-I tend to have bluer colors. With optical and UV photometry, we construct the bolometric luminosity and derive a bolometric correction relation that is generally applicable for converting g, r-band photometry to the bolometric luminosity for SLSNe-I.
We present analysis of the light curves (LCs) of 77 hydrogen-poor superluminous supernovae (SLSNe I) discovered during the Zwicky Transient Facility Phase I operation. We find that the majority (67%) of the sample can be fit equally well by both magnetar and ejecta–circumstellar medium (CSM) interaction plus 56Ni decay models. This implies that LCs alone cannot unambiguously constrain the physical power sources for an SLSN I. However, 23% of the sample show inverted V-shape, steep-declining LCs or features of long rise and fast post-peak decay, which are better described by the CSM+Ni model. The remaining 10% of the sample favors the magnetar model. Moreover, our analysis shows that the LC undulations are quite common, with a fraction of 18%–44% in our gold sample. Among those strongly undulating events, about 62% of them are found to be CSM-favored, implying that the undulations tend to occur in the CSM-favored events. Undulations show a wide range in energy and duration, with median values (and 1σ errors) being as and days, respectively. Our analysis of the undulation timescales suggests that intrinsic temporal variations of the central engine can explain half of the undulating events, while CSM interaction (CSI) can account for the majority of the sample. Finally, all of the well-observed He-rich SLSNe Ib either have strongly undulating LCs or the LCs are much better fit by the CSM+Ni model. These observations imply that their progenitor stars have not had enough time to lose all of the He-envelopes before supernova explosions, and H-poor CSM are likely to present in these events.
We present an empirical study of contamination in wide-field optical follow-up searches of gravitational wave sources from Advanced LIGO/Virgo using dedicated observations with the Dark Energy Camera. Our search covered similar to 56 deg(2), with two visits per night, in the i and z bands, followed by an additional set of griz images three weeks later to serve as reference images for subtraction. We achieve 5 sigma point-source limiting magnitudes of i approximate to 23.5 and z approximate to 22.4 mag in the coadded single-epoch images. We conduct a search for transient objects that mimic the i - z color behavior of both red (i-z > 0.5 mag) and blue (i-z < 0 mag) kilonova emission, finding 11 and 10 contaminants, respectively. Independent of color, we identify 48 transients of interest. Additionally, we leverage the rapid cadence of our observations to search for sources with characteristic timescales of approximate to 1 day and approximate to 3 hr, finding no potential contaminants. We assess the efficiency of our search with injected point sources, finding that we are 90% (60%) efficient when searching for red (blue) kilonova-like sources to a limiting magnitude of i less than or similar to 22.5 mag. Using our efficiencies, we derive sky rates for kilonova contaminants of R-red approximate to 0.16 deg(-2) and R-blue approximate to 0.80 deg(-2). The total contamination rate is R-all approximate to 1.79 deg(-2). We compare our results to previous optical follow-up efforts and comment on the outlook for gravitational wave follow-up searches as additional detectors (e.g., KAGRA, LIGO India) come online in the next decade.
Compact neutron star binary systems are produced from binary massive stars through stellar evolution involving up to two supernova explosions. The final stages in the formation of these systems have not been directly observed. We report the discovery of iPTF 14gqr (SN 2014ft), a type Ic supernova with a fast-evolving light curve indicating an extremely low ejecta mass (approximate to 0.2 solar masses) and low kinetic energy (approximate to 2 x 10(50) ergs). Early photometry and spectroscopy reveal evidence of shock cooling of an extended helium-rich envelope, likely ejected in an intense pre-explosion mass-loss episode of the progenitor. Taken together, we interpret iPTF 14gqr as evidence for ultra-stripped supernovae that form neutron stars in compact binary systems.
Calcium-rich gap transients represent an intriguing new class of faint and fast-evolving supernovae that exhibit strong [Ca II] emission in their nebular phase spectra. In this paper, we present the discovery and follow-up observations of a faint and fast-evolving transient, iPTF 16hgs, that exhibited a double-peaked light curve. Exhibiting a Type Ib spectrum in the photospheric phase and an early transition to a [Ca II] dominated nebular phase, iPTF 16hgs shows properties consistent with the class of Ca-rich gap transients, with two important exceptions. First, while the second peak of the light curve is similar to other Ca-rich gap transients, the first blue and fast-fading peak (declining over approximate to 2 days) is unique to this source. Second, we find that iPTF 16hgs occurred in the outskirts (projected offset of approximate to 6 kpc approximate to 1.9 R-eff) of a low-metallicity (approximate to 0.4 Z(circle dot)), star-forming, dwarf spiral galaxy. Deep limits from late-time radio observations suggest a low-density environment for the source. If iPTF 16hgs shares explosion physics with the class of Ca-rich gap transients, the first peak can be explained by the presence of 0.01 M-circle dot of Ni-56 in the outer layers the ejecta, reminiscent of some models of He-shell detonations on WDs. However, if iPTF 16hgs is physically unrelated to the class, the first peak is consistent with shock cooling emission (of an envelope with a mass of approximate to 0.08 M-circle dot and radius of approximate to 13 R-circle dot) in a core-collapse explosion of a highly stripped massive star in a close binary system.
Using the Zwicky Transient Facility alert stream, we are conducting a large spectroscopic campaign to construct a complete, volume-limited sample of transients brighter than 20 mag, and coincident within 100 '' of galaxies in the Census of the Local Universe catalog. We describe the experiment design and spectroscopic completeness from the first 16 months of operations, which have classified 754 supernovae. We present results from a systematic search for calcium-rich gap transients in the sample of 22 low-luminosity (peak absolute magnitude M > -17), hydrogen-poor events found in the experiment. We report the detection of eight new events, and constrain their volumetric rate to greater than or similar to 15% +/- 5% of the SN Ia rate. Combining this sample with 10 previously known events, we find a likely continuum of spectroscopic properties ranging from events with SN Ia-like features (Ca-Ia objects) to those with SN Ib/c-like features (Ca-Ib/c objects) at peak light. Within the Ca-Ib/c events, we find two populations distinguished by their red (g - r approximate to 1.5 mag) or green (g - r approximate to 0.5 mag) colors at the r-band peak, wherein redder events show strong line blanketing features and slower light curves (similar to Ca-Ia objects), weaker He lines, and lower [Ca II]/[O I] in the nebular phase. We find that all together the spectroscopic continuum, volumetric rates, and striking old environments are consistent with the explosive burning of He shells on low-mass white dwarfs. We suggest that Ca-Ia and red Ca-Ib/c objects arise from the double detonation of He shells, while green Ca-Ib/c objects are consistent with low-efficiency burning scenarios like detonations in low-density shells or deflagrations.
Key information about the progenitor system and the explosion mechanism of Type la supernovae (SNe Ia) can be obtained from early observations, within a few days from explosion. iPTF16abc was discovered as a young SN la with excellent early time data. Here, we present photometry and spectroscopy of the SN in the nebular phase. A comparison of the early time data with a sample of SNe la shows distinct features, differing from normal SNe la at early phases but similar to normal SNe Ia at a few weeks after maximum light (i.e. the transitional phase) and well into the nebular phase. The transparency time-scales (t(0)) for this sample of SNe Ia range between similar to 25 and 41 d indicating a diversity in the ejecta masses. t(0) also weakly correlates with the peak bolometric luminosity, consistent with the interpretation that SNe with higher ejecta masses would produce more Ni-56. Comparing the to and the maximum luminosity, L-max distribution of a sample of SNe Ia to predictions from a wide range of explosion models we find an indication that the sub-Chandrasekhar mass models span the range of observed values. However, the bright end of the distribution can be better explained by Chandrasekhar mass delayed detonation models, hinting at multiple progenitor channels to explain the observed bolometric properties of SNe Ia. iPTF16abc appears to be consistent with the predictions from the M-ch models.
We present the detection of an unresolved radio source coincident with the position of the Type I superluminous supernova (SLSN) PTF10hgi (z = 0.098) about 7.5 yr post-explosion, with a flux density of F-nu(6 GHz) approximate to 47.3 mu Jy and a luminosity of L-nu(6 GHz) approximate to 1.1 x 10(28) erg s(-1) Hz(-1). This represents the first detection of radio emission coincident with an SLSN on any timescale. We investigate various scenarios for the origin of the radio emission: star formation activity, an active galactic nucleus, and a non-relativistic supernova blastwave. While any of these would be quite novel if confirmed, none appear likely when considered within the context of the other properties of the host galaxy, previous radio observations of SLSNe, and the general population of hydrogen-poor supernovae (SNe). Instead, the radio emission is reminiscent of the quiescent radio source associated with the repeating FRB 121102, which has been argued to be powered by a magnetar born in a SLSN or long gamma-ray burst explosion several decades ago. We show that the properties of the radio source are consistent with a magnetar wind nebula or an off-axis jet, indicating the presence of a central engine. Our directed search for fast radio bursts from the location of PTF10hgi using 40 minutes of Very Large Array phased-array data reveals no detections to a limit of 22 mJy (10 sigma; 10 ms duration). We outline several follow-up observations that can conclusively establish the origin of the radio emission.
We present and discuss the optical spectrophotometric observations of the nearby (z = 0.087) Type I superluminous supernova (SLSN I) SN 2017gci, whose peak K-corrected absolute magnitude reaches M-g = -21.5 mag. Its photometric and spectroscopic evolution includes features of both slow- and of fast-evolving SLSN I, thus favoring a continuum distribution between the two SLSN-I subclasses. In particular, similarly to other SLSNe I, the multiband light curves (LCs) of SN 2017gci show two re-brightenings at about 103 and 142 d after the maximum light. Interestingly, this broadly agrees with a broad emission feature emerging around 6520 angstrom after similar to 51 d from the maximum light, which is followed by a sharp knee in the LC. If we interpret this feature as H alpha, this could support the fact that the bumps are the signature of late interactions of the ejecta with a (hydrogen-rich) circumstellar material. Then we fitted magnetar- and CSM-interaction-powered synthetic LCs on to the bolometric one of SN 2017gci. In the magnetar case, the fit suggests a polar magnetic field B-p similar or equal to 6 x 10(14) G, an initial period of the magnetar P-initial similar or equal to 2.8 ms, an ejecta mass M-ejecta similar or equal to 9M(circle dot) and an ejecta opacity kappa similar or equal to 0.08 cm(2) g(-1). A CSM-interaction scenario would imply a CSM mass similar or equal to 5 M-circle dot and an ejecta mass similar or equal to 12M(circle dot). Finally, the nebular spectrum of phase + 187 d was modeled, deriving a mass of similar or equal to 10 M-circle dot for the ejecta. Our models suggest that either a magnetar or CSM interaction might be the power sources for SN 2017gci and that its progenitor was a massive (40 M-circle dot) star.
We present a comprehensive optical and near-infrared census of the fields of 90 short gamma-ray bursts (GRBs) discovered in 2005–2021, constituting all short GRBs for which host galaxy associations are feasible (≈60% of the total Swift short GRB population). We contribute 274 new multi-band imaging observations across 58 distinct GRBs and 26 spectra of their host galaxies. Supplemented by literature and archival survey data, the catalog contains 542 photometric and 42 spectroscopic data sets. The photometric catalog reaches 3σ depths of ≳24–27 mag and ≳23–26 mag for the optical and near-infrared bands, respectively. We identify host galaxies for 84 bursts, in which the most robust associations make up 56% (50/90) of events, while only a small fraction, 6.7%, have inconclusive host associations. Based on new spectroscopy, we determine 18 host spectroscopic redshifts with a range of z ≈ 0.15–1.5 and find that ≈23%–41% of Swift short GRBs originate from z > 1. We also present the galactocentric offset catalog for 84 short GRBs. Taking into account the large range of individual measurement uncertainties, we find a median of projected offset of ≈7.7 kpc, for which the bursts with the most robust associations have a smaller median of ≈4.8 kpc. Our catalog captures more high-redshift and low-luminosity hosts, and more highly offset bursts than previously found, thereby diversifying the population of known short GRB hosts and properties. In terms of locations and host luminosities, the populations of short GRBs with and without detectable extended emission are statistically indistinguishable. This suggests that they arise from the same progenitors, or from multiple progenitors, which form and evolve in similar environments. All of the data products are available on the Broadband Repository for Investigating Gamma-Ray Burst Host Traits website.
We present an analysis of 507 spectra of 173 stripped-envelope (SE) supernovae (SNe) discovered by the untargeted Palomar Transient Factory (PTF) and intermediate PTF (iPTF) surveys. Our sample contains 55 Type IIb SNe (SNe 45 Type Ib SNe (SNe IIb), 56 Type Ic SNe (SNe Ic), and 17 Type Ib/c SNe (SNe Ib/c). We have compared the SE SN subtypes via measurements of the pseudo-equivalent widths (pEWs) and velocities of the He I lambda lambda 5876, 7065 and O I lambda 7774 absorption lines. Consistent with previous work, we find that SNe Ic show higher pEWs and velocities in O I lambda 7774 compared to SNe IIb and Ib. The pEWs of the He I lambda lambda 5876, 7065 lines are similar in SNe Ib and IIb after maximum light. The He I lambda lambda 5876, 7065 velocities at maximum light are higher in SNe Ib compared to SNe IIb. We identify an anticorrelation between the He I lambda 7065 pEW and O I lambda 7774 velocity among SNe IIb and Ib. This can be interpreted as a continuum in the amount of He present at the time of explosion. It has been suggested that SNe Ib and Ic have similar amounts of He, and that lower mixing could be responsible for hiding He in SNe Ic. However, our data contradict this mixing hypothesis. The observed difference in the expansion rate of the ejecta around maximum light of SNe Ic (V-m root 2E(k)/M-ej approximate to 15 000 km s(-1)) and SNe Ib (V-m approximate to 9000 km s(-1)) would imply an average He mass difference of similar to 1.4 M-circle dot, if the other explosion parameters are assumed to be unchanged between the SE SN subtypes. We conclude that SNe Ic do not hide He but lose He due to envelope stripping.
The Zwicky Transient Facility (ZTF), a public-private enterprise, is a new time-domain survey employing a dedicated camera on the Palomar 48-inch Schmidt telescope with a 47 deg(2) field of view and an 8 second readout time. It is well positioned in the development of time-domain astronomy, offering operations at 10% of the scale and style of the Large Synoptic Survey Telescope (LSST) with a single 1-m class survey telescope. The public surveys will cover the observable northern sky every three nights in g and r filters and the visible Galactic plane every night in g and r. Alerts generated by these surveys are sent in real time to brokers. A consortium of universities that provided funding (partnership) are undertaking several boutique surveys. The combination of these surveys producing one million alerts per night allows for exploration of transient and variable astrophysical phenomena brighter than r similar to 20.5 on timescales of minutes to years. We describe the primary science objectives driving ZTF, including the physics of supernovae and relativistic explosions, multi-messenger astrophysics, supernova cosmology, active galactic nuclei, and tidal disruption events, stellar variability, and solar system objects.
We present detailed observations of ZTF18abukavn (SN2018gep), discovered in high-cadence data from the Zwicky Transient Facility as a rapidly rising (1.4 +/- 0.1 mag hr(-1)) and luminous (M-g,M- peak = -20 mag) transient. It is spectroscopically classified as a broad-lined stripped-envelope supernova (Ic-BL SN). The high peak luminosity (L-bol greater than or similar to 3 x 10(44) erg s(-1)), the short rise time (t(rise) = 3 days in g band), and the blue colors at peak (g-r similar to -0.4) all resemble the high-redshift Ic-BL iPTF16asu, as well as several other unclassified fast transients. The early discovery of SN2018gep (within an hour of shock breakout) enabled an intensive spectroscopic campaign, including the highest-temperature (T-eff greater than or similar to 40,000 K) spectra of a stripped-envelope SN. A retrospective search revealed luminous (M-g similar to M-r approximate to -14 mag) emission in the days to weeks before explosion, the first definitive detection of precursor emission for a Ic-BL. We find a limit on the isotropic gamma-ray energy release E-gamma,E- iso < 4.9 x 10(48) erg, a limit on X-ray emission L-X < 10(40) erg s(-1), and a limit on radio emission nu L-v less than or similar to 10(37) erg s(-1). Taken together, we find that the early (< 10 days) data are best explained by shock breakout in a massive shell of dense circumstellar material (0.02 M-circle dot) at large radii (3 x 10(14) cm) that was ejected in eruptive pre-explosion mass-loss episodes. The late-time (> 10 days) light curve requires an additional energy source, which could be the radioactive decay of Ni-56.
We present optical, radio, and X-ray observations of SN 2020bvc (=ASASSN-20bs, ZTF 20aalxlis), a nearby (z = 0.0252; d.=.114Mpc) broad-line (BL) Type Ic supernova (SN) and the first double-peaked Ic-BL discovered without a gamma-ray burst (GRB) trigger. Our observations show that SN 2020bvc shares several properties in common with the Ic-BL SN 2006aj, which was associated with the low-luminosity gamma-ray burst (LLGRB) 060218. First, the 10 GHz radio luminosity (L-radio approximate to 10(37) erg s(-1)) is brighter than ordinary core-collapse SNe but fainter than LLGRB SNe such as SN 1998bw (associated with LLGRB 980425). We model our VLA observations (spanning 13-43 days) as synchrotron emission from a mildly relativistic (v greater than or similar to 0.3c) forward shock. Second, with Swift and Chandra, we detect X-ray emission (L-X approximate to 10(41) erg s(-1)) that is not naturally explained as inverse Compton emission or part of the same synchrotron spectrum as the radio emission. Third, high-cadence (6x night(-1)) data from the Zwicky Transient Facility (ZTF) show a double-peaked optical light curve, the first peak from shock cooling of extended low-mass material (mass M-e < 10(-2) M-circle dot at radius R-e > 10(12) cm) and the second peak from the radioactive decay of 56Ni. SN 2020bvc is the first double-peaked Ic-BL SN discovered without a GRB trigger, so it is noteworthy that it shows X-ray and radio emission similar to LLGRB SNe. For four of the five other nearby (z less than or similar to 0.05) Ic-BL SNe with ZTF high-cadence data, we rule out a first peak like that seen in SN 2006aj and SN 2020bvc, i.e., that lasts approximate to 1 day.and reaches a peak luminosity M approximate to -18. Follow-up X-ray and radio observations of Ic-BL SNe with well-sampled early optical light curves will establish whether double-peaked optical light curves are indeed predictive of LLGRB-like X-ray and radio emission.
We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above half-maximum light 1 day < t (1/2) < 12 days, of which 28 have blue (g - r less than or similar to -0.2 mag) colors at peak light. Of the 38 transients (28 FBOTs), 19 (13) can be spectroscopically classified as core-collapse supernovae (SNe): 11 (8) H- or He-rich (Type II/IIb/Ib) SNe, 6 (4) interacting (Type IIn/Ibn) SNe, and 2 (1) H&He-poor (Type Ic/Ic-BL) SNe. Two FBOTs (published previously) had predominantly featureless spectra and luminous radio emission: AT2018lug (The Koala) and AT2020xnd (The Camel). Seven (five) did not have a definitive classification: AT 2020bdh showed tentative broad H alpha in emission, and AT 2020bot showed unidentified broad features and was 10 kpc offset from the center of an early-type galaxy. Ten (eight) have no spectroscopic observations or redshift measurements. We present multiwavelength (radio, millimeter, and/or X-ray) observations for five FBOTs (three Type Ibn, one Type IIn/Ibn, one Type IIb). Additionally, we search radio-survey (VLA and ASKAP) data to set limits on the presence of radio emission for 24 of the transients. All X-ray and radio observations resulted in nondetections; we rule out AT2018cow-like X-ray and radio behavior for five FBOTs and more luminous emission (such as that seen in the Camel) for four additional FBOTs. We conclude that exotic transients similar to AT2018cow, the Koala, and the Camel represent a rare subset of FBOTs and use ZTF's SN classification experiments to measure the rate to be at most 0.1% of the local core-collapse SN rate.
The classification of supernovae (SNe) and its impact on our understanding of explosion physics and progenitors have traditionally been based on the presence or absence of certain spectral features. However, current and upcoming wide-field time-domain surveys have increased the transient discovery rate far beyond our capacity to obtain even a single spectrum of each new event. We must therefore rely heavily on photometric classification-connecting SN light curves back to their spectroscopically defined classes. Here, we present Superphot, an open-source Python implementation of the machine-learning classification algorithm of Villar et al., and apply it to 2315 previously unclassified transients from the Pan-STARRS1 Medium Deep Survey for which we obtained spectroscopic host-galaxy redshifts. Our classifier achieves an overall accuracy of 82%, with completenesses and purities of >80% for the best classes (SNe Ia and superluminous SNe). For the worst performing SN class (SNe Ibc), the completeness and purity fall to 37% and 21%, respectively. Our classifier provides 1257 newly classified SNe Ia, 521 SNe II, 298 SNe Ibc, 181 SNe IIn, and 58 SLSNe. These are among the largest uniformly observed samples of SNe available in the literature and will enable a wide range of statistical studies of each class.
We present results from a systematic selection of tidal disruption events (TDEs) in a wide-area (4800 deg(2)), g+ R band, Intermediate Palomar Transient Factory experiment. Our selection targets typical optically selected TDEs: bright (> 60% flux increase) and blue transients residing in the centers of red galaxies. Using photometric selection criteria to down-select from a total of 493 nuclear transients to a sample of 26 sources, we then use follow-up UV imaging with the Neil Gehrels Swift Telescope, ground-based optical spectroscopy, and light curve fitting to classify them as 14 Type Ia supernovae (SNe Ia), 9 highly variable active galactic nuclei (AGNs), 2 confirmed TDEs, and 1 potential core-collapse supernova. We find it possible to filter AGNs by employing a more stringent transient color cut (g - r < -0.2 mag); further, UV imaging is the best discriminator for filtering SNe, since SNe Ia can appear as blue, optically, as TDEs in their early phases. However, when UV-optical color is unavailable, higher-precision astrometry can also effectively reduce SNe contamination in the optical. Our most stringent optical photometric selection criteria yields a 4.5: 1 contamination rate, allowing for a manageable number of TDE candidates for complete spectroscopic follow-up and real-time classification in the Zwicky Transient Facility era. We measure a TDE per galaxy rate of 1.7(-1.3)(+2.9) 10(-4) gal yr(-1) (90% CL in Poisson statistics). This does not account for TDEs outside our selection criteria, and thus may not reflect the total TDE population, which is yet to be fully mapped.
Type II supernovae (SNe) stem from the core collapse of massive (>8 M-circle dot) stars. Due to their short lifespan, we expect a very low rate of such events in elliptical hosts, where the star formation rate is low, and which are mostly comprised of an old stellar population. SN 2016hil (iPTF16hil) is an SN II located in the extreme outskirts of an elliptical galaxy at z.=.0.0608 (projected distance 27.2 kpc). It was detected near peak (M-r similar to -17 mag) 9 days after the last non-detection. The event has some potentially peculiar properties: it presented an apparently double-peaked light curve, and its spectra suggest low metallicity content (Z < 0.4 Z(circle dot)). We place a tentative upper limit on the mass of a potential faint host at log M/M-circle dot = 7.27(-0.24)(+0.43) using deep optical imaging from Keck/LRIS. In light of this, we discuss the possibility of the progenitor forming locally and other more exotic formation scenarios such as a merger or common-envelope evolution causing a time-delayed explosion. Further observations of the explosion site in the UV are needed in order to distinguish between the cases. Regardless of the origin of the transient, observing a population of such seemingly hostless SNe II could have many uses, including an estimate the amount of faint galaxies in a given volume, and tests of the prediction of a time-delayed population of core-collapse SNe in locations otherwise unfavorable for the detection of such events.
We report the results from spectroscopic observations of the multiple images of the strongly lensed Type Ia supernova (SN Ia), iPTF16geu, obtained with ground-based telescopes and the Hubble Space Telescope (HST). From a single epoch of slitless spectroscopy with HST, we resolve spectra of individual lensed supernova images for the first time. This allows us to perform an independent measurement of the time-delay between the two brightest images, Delta t = 1.4 +/- 5.0 d, which is consistent with the time-delay measured from the light curves. We also present measurements of narrow emission and absorption lines characterizing the interstellar medium in the SN Ia host galaxy at z = 0.4087, as well as in the foreground lensing galaxy at z = 0.2163. We detect strong Naid absorption in the host galaxy, indicating that iPTF16geu belongs to a subclass of SNe Ia displaying 'anomalously' large Naid column densities compared to dust extinction derived from light curves. For the lens galaxy, we refine the measurement of the velocity dispersion, sigma = 129 +/- 4 kms(-1), which significantly constrains the lens model. We use ground-based spectroscopy, boosted by a factor similar to 70 from lensing magnification, to study the properties of a high-z SN Ia with unprecedented signal-to-noise ratio. The spectral properties of the supernova, such as pseudo-Equivalent widths of several absorption features and velocities of the Si II-line, indicate that iPTF16geu is a normal SN Ia. We do not detect any significant deviations of the SN spectral energy distribution from microlensing of the SN photosphere by stars and compact objects in the lensing galaxy.
We present a sample of 14 hydrogen-rich superluminous supernovae (SLSNe II) from the Zwicky Transient Facility (ZTF) between 2018 and 2020. We include all classified SLSNe with peaks Mg < −20 mag with observed broad but not narrow Balmer emission, corresponding to roughly 20 per cent of all hydrogen-rich SLSNe in ZTF phase I. We examine the light curves and spectra of SLSNe II and attempt to constrain their power source using light-curve models. The brightest events are photometrically and spectroscopically similar to the prototypical SN 2008es, while others are found spectroscopically more reminiscent of non-superluminous SNe II, especially SNe II-L. 56Ni decay as the primary power source is ruled out. Light-curve models generally cannot distinguish between circumstellar interaction (CSI) and a magnetar central engine, but an excess of ultraviolet (UV) emission signifying CSI is seen in most of the SNe with UV data, at a wide range of photometric properties. Simultaneously, the broad H α profiles of the brightest SLSNe II can be explained through electron scattering in a symmetric circumstellar medium (CSM). In other SLSNe II without narrow lines, the CSM may be confined and wholly overrun by the ejecta. CSI, possibly involving mass lost in recent eruptions, is implied to be the dominant power source in most SLSNe II, and the diversity in properties is likely the result of different mass loss histories. Based on their radiated energy, an additional power source may be required for the brightest SLSNe II, however – possibly a central engine combined with CSI.
We present a nuclear transient event, PS1-13cbe, that was first discovered in the Pan-STARRS1 survey in 2013. The outburst occurred in the nucleus of the galaxy SDSS J222153.87+003054.2 at z = 0.123 55, which was classified as a Seyfert 2 in a pre-outburst archival Sloan Digital Sky Survey (SDSS) spectrum. PS1-13cbe showed the appearance of strong broad H alpha and H beta emission lines and a non-stellar continuum in a Magellan spectrum taken 57 d after the peak of the outburst that resembled the characteristics of a Seyfert 1. These broad lines were not present in the SDSS spectrum taken a decade earlier and faded away within 2 yr, as observed in several late-time MDM spectra. We argue that the dramatic appearance and disappearance of the broad lines and a factor of similar to 8 increase in the optical continuum are most likely caused by variability in the pre-existing accretion disc than a tidal disruption event, supernova, or variable obscuration. The time-scale for the turn-on of the optical emission of similar to 70 d observed in this transient is among the shortest observed in a 'changing-look' active galactic nucleus,
Context. Type Ibn supernovae (SNe Ibn) are a rare class of stripped envelope supernovae interacting with a helium-rich circumstellar medium (CSM). The majority of the SNe Ibn reported in the literature display a surprising homogeneity in their fast-evolving lightcurves and are typically found in actively starforming spiral galaxies.
Aims. We present the discovery and the study of SN 2020bqj (ZTF20aalrqbu), a SN Ibn with a long-duration peak plateau lasting 40 days and hosted by a faint low-mass galaxy. We aim to explain its peculiar properties using an extensive photometric and spectroscopic data set.
Methods. We compare the photometric and spectral evolution of SN 2020bqj with regular SNe Ibn from the literature, as well as with other outliers in the SN Ibn subclass. We fit the bolometric and multi-band lightcurves with powering mechanism models such as radioactive decay and CSM interaction. We also model the host galaxy of SN 2020bqj.
Results. The risetime, peak magnitude and spectral features of SN 2020bqj are consistent with those of most SNe Ibn, but the SN is a clear outlier in the subclass based on its bright, long-lasting peak plateau and the low mass of its faint host galaxy. We show through modeling that the lightcurve of SN 2020bqj can be powered predominantly by shock heating from the interaction of the SN ejecta and a dense CSM, combined with radioactive decay. The peculiar Type Ibn SN 2011hw is a close analog to SN 2020bqj in terms of lightcurve and spectral evolution, suggesting a similar progenitor and CSM scenario. In this scenario a very massive progenitor star in the transitional phase between a luminous blue variable and a compact Wolf-Rayet star undergoes core-collapse, embedded in a dense helium-rich CSM with an elevated opacity compared to normal SNe Ibn, due to the presence of residual hydrogen. This scenario is consistent with the observed properties of SN 2020bqj and the modeling results.
Conclusions. SN 2020bqj is a compelling example of a transitional SN Ibn/IIn based on not only its spectral features, but also its lightcurve, host galaxy properties and the inferred progenitor properties. The strong similarity with SN 2011hw suggests this subclass may be the result of a progenitor in a stellar evolution phase that is distinct from those of progenitors of regular SNe Ibn.
We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0-294811.0 with an orbital period of P-orb = 44.66279 +/- 1.16 x 10(-4) minutes, making it the most compact hot subdwarf binary known. Spectroscopic observations using the VLT, Gemini and Keck telescopes revealed a He-sdOB primary with an intermediate helium abundance, T-eff = 39 400 +/- 500 K and log g = 5.74 +/- 0.09. High signal-to-noise ratio light curves show strong ellipsoidal modulation resulting in a derived sdOB mass M-sdOB= 0.23 +/- 0.12 M-circle dot with a WD companion (M-WD = 0.72 +/- 0.17 M-circle dot). The mass ratio was found to be q = M-sdOB/M-WD = 0.32 +/- 0.10. The derived mass for the He-sdOB is inconsistent with the canonical mass for hot subdwarfs of approximate to 0.47 M-circle dot. To put constraints on the structure and evolutionary history of the sdOB star we compared the derived T-eff, log g, and sdOB mass to evolutionary tracks of helium stars and helium white dwarfs calculated with Modules for Experiments in Stellar Astrophysics (MESA). We find that the best-fitting model is a helium white dwarf with a mass of 0.320 M-circle dot, which left the common envelope approximate to 1.1 Myr ago, which is consistent with the observations. As a helium white dwarf with a massive white dwarf companion, the object will reach contact in 17.6 Myr at an orbital period of 5 minutes. Depending on the spin-orbit synchronization timescale the object will either merge to form an R CrB star or end up as a stably accreting AM CVn-type system with a helium white dwarf donor.
We present detailed multiwavelength observations of GRB 161219B at z = 0.1475, spanning the radio to X-ray regimes, and the first Atacama Large Millimeter/submillimeter Array (ALMA) light curve of a gamma-ray burst (GRB) afterglow. The centimeter- and millimeter-band observations before 8.5 days require emission in excess of that produced by the afterglow forward shock (FS). These data are consistent with radiation from a refreshed reverse shock (RS) produced by the injection of energy into the FS, signatures of which are also present in the X-ray and optical light curves. We infer a constant-density circumburst environment with an extremely low density, n(0) approximate to 3 x 10(-4 )cm(-3), and show that this is a characteristic of all strong RS detections to date. The Karl G. Lansky Very Large Array (VLA) observations exhibit unexpected rapid variability on roughly minute timescales, indicative of strong interstellar scintillation. The X-ray, ALMA, and VLA observations together constrain the jet break time, t(jet) approximate to 32 days, yielding a wide jet opening angle of theta(jet) approximate to 13 degrees, implying beaming-corrected gamma-ray and kinetic energies of E-gamma approximate to 4.9 x 10(48) erg and E-K approximate to 1.3 x 10(50) erg, respectively. Comparing the RS and FS emission, we show that the ejecta are only weakly magnetized, with relative magnetization, R-B approximate to 1, compared to the FS. These direct, multifrequency measurements of a refreshed RS spanning the optical to radio bands highlight the impact of radio and millimeter data in probing the production and nature of GRB jets.
Superluminous supernovae are among the most energetic stellar explosions in the Universe, but their energy sources remain an open question. Here we present long-term observations of one of the closest examples of the hydrogen-poor superluminous supernovae subclass SLSNe-I, supernova SN 2017egm, revealing the most complicated known luminosity evolution of SLSNe-I. Three distinct post-peak bumps were recorded in its light curve collected at about 100–350 days after maximum brightness, challenging current popular power models such as magnetar, fallback accretion, and interaction between ejecta and a circumstellar shell. However, the complex light curve can be well modelled by successive interactions with multiple circumstellar shells with a total mass of about 6.8–7.7 M⊙. In this scenario, large energy deposition from interaction-induced reverse shocks results in ionization of neutral oxygen in the supernova ejecta and hence a much lower nebular-phase line ratio of [O I] λ6,300/([Ca II] + [O II]) λ7,300 (~0.2) compared with that derived for other superluminous and normal stripped-envelope supernovae. The pre-existing multiple shells indicate that the progenitor of SN 2017egm experienced pulsational mass ejections triggered by pair instability within 2 years before explosion, in robust agreement with theoretical predictions for a pre-pulsation helium-core mass of 48–51 M⊙.
We present light curves and classification spectra of 17 hydrogen-poor superluminous supernovae (SLSNe) from the Pan-STARRS1 Medium Deep Survey (PS1 MDS). Our sample contains all objects from the PS1. MDS sample with spectroscopic classification that are similar to either of the prototypes SN 2005ap or SN 2007bi, without an explicit limit on luminosity. With a redshift range 0.3 < z < 1.6, PS1. MDS is the first SLSN sample primarily probing the high-redshift population; our multifilter PS1 light curves probe the rest-frame UV emission, and hence the peak of the spectral energy distribution. We measure the temperature evolution and construct bolometric light curves, and find peak luminosities of (0.5-5) x 10(44) erg s(-1) and lower limits on the total radiated energies of (0.3-2) x 10(51) erg. The light curve shapes are diverse, with both rise and decline times spanning a factor of similar to 5 and several examples of double-peaked light curves. When correcting for the flux-limited nature of our survey, we find a median peak luminosity at 4000 angstrom of M-4000 = -21.1 mag and a spread of sigma = 0.7 mag.
Hydrogen-poor superluminous supernovae (SLSN-I) are a class of rare and energetic explosions that have been discovered in untargeted transient surveys in the past decade(1,2). The progenitor stars and the physical mechanism behind their large radiated energies (about 1O(51) erg or 1O(44) J) are both debated, with one class of models primarily requiring a large rotational energy(3,4) and the other requiring very massive progenitors that either convert kinetic energy into radiation through interaction with circumstellar material (CSM)(5-8 )or engender an explosion caused by pair-instability (loss of photon pressure due to particle-antiparticle production)(9,10). Observing the structure of the CSM around SLSN-I offers a powerful test of some scenarios, although direct observations are scarce(11,)(12). Here, we present a series of spectroscopic observations of the SLSN-I iPTF16eh, which reveal both absorption and time- and frequency-variable emission in the Mg n resonance doublet. We show that these observations are naturally explained as a resonance scattering light echo from a circumstellar shell. Modelling the evolution of the emission, we infer a shell radius of 0.1 pc and velocity of 3,300 km s(-1), implying that the shell was ejected three decades before the supernova explosion. These properties match theoretical predictions of shell ejections occurring because of pulsational pair-instability and imply that the progenitor had a helium core mass of about 50-55 M-circle dot, corresponding to an initial mass of about 115 M-circle dot.
We present photometry and spectroscopy of four hydrogen-poor luminous supernovae discovered during the 2-month long science commissioning and early operations of the Zwicky Transient Facility (ZTF) survey. Three of these objects, SN 2018bym (ZTF18aapgrxo), SN 2018avk (ZTF18aaisyyp), and SN 2018bgv (ZTF18aavrmcg), resemble typical SLSN-I spectroscopically, while SN 2018don (ZTF18aajqcue) may be an object similar to SN 2007bi experiencing considerable host galaxy reddening, or an intrinsically long-lived, luminous, and red SN Ic. We analyze the light curves, spectra, and host galaxy properties of these four objects and put them in context of the population of SLSN-I. SN 2018bgv stands out as the fastest-rising SLSN-I observed to date, with a rest-frame g-band rise time of just 10 days from explosion to peak—if it is powered by magnetar spin-down, the implied ejecta mass is only 1 M ⊙. SN 2018don also displays unusual properties—in addition to its red colors and comparatively massive host galaxy, the light curve undergoes some of the strongest light-curve undulations postpeak seen in an SLSN-I, which we speculate may be due to interaction with circumstellar material. We discuss the promises and challenges of finding SLSNe in large-scale surveys like ZTF given the observed diversity in the population.
The Zwicky Transient Facility is a large optical survey in multiple filters producing hundreds of thousands of transient alerts per night. We describe here various machine learning (ML) implementations and plans to make the maximal use of the large data set by taking advantage of the temporal nature of the data, and further combining it with other data sets. We start with the initial steps of separating bogus candidates from real ones, separating stars and galaxies, and go on to the classification of real objects into various classes. Besides the usual methods (e.g., based on features extracted from light curves) we also describe early plans for alternate methods including the use of domain adaptation, and deep learning. In a similar fashion we describe efforts to detect fast moving asteroids. We also describe the use of the Zooniverse platform for helping with classifications through the creation of training samples, and active learning. Finally we mention the synergistic aspects of ZTF and LSST from the ML perspective.
The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to thermal energy. In 'superluminous' supernovae of type IIn-named for narrow hydrogen lines(1) in their spectra-the integrated emission can reach(2-6) similar to 10(51) erg, attainable by thermalizing most of the kinetic energy of a conventional supernova. A few transients in the centres of active galaxies have shown similar spectra and even larger energies(7,8), but are difficult to distinguish from accretion onto the supermassive black hole. Here we present a new event, SN2016aps, offset from the centre of a low-mass galaxy, that radiated greater than or similar to 5 x 10(51) erg, necessitating a hyper-energetic supernova explosion. We find a total (supernova ejecta + CSM) mass likely exceeding 50-100 M-circle dot, with energy greater than or similar to 10(52) erg, consistent with some models of pair-instability supernovae or pulsational pair-instability supernovae-theoretically predicted thermonuclear explosions from helium cores >50 M-circle dot. Independent of the explosion mechanism, this event demonstrates the existence of extremely energetic stellar explosions, detectable at very high redshifts, and provides insight into dense CSM formation in the most massive stars.
We present observations of SN 2021csp, the second example of a newly identified type of supernova (SN) hallmarked by strong, narrow, P Cygni carbon features at early times (Type Icn). The SN appears as a fast and luminous blue transient at early times, reaching a peak absolute magnitude of −20 within 3 days due to strong interaction between fast SN ejecta (v ≈ 30,000 km s−1) and a massive, dense, fast-moving C/O wind shed by the WC-like progenitor months before explosion. The narrow-line features disappear from the spectrum 10–20 days after explosion and are replaced by a blue continuum dominated by broad Fe features, reminiscent of Type Ibn and IIn supernovae and indicative of weaker interaction with more extended H/He-poor material. The transient then abruptly fades ∼60 days post-explosion when interaction ceases. Deep limits at later phases suggest minimal heavy-element nucleosynthesis, a low ejecta mass, or both, and imply an origin distinct from that of classical Type Ic SNe. We place SN 2021csp in context with other fast-evolving interacting transients, and discuss various progenitor scenarios: an ultrastripped progenitor star, a pulsational pair-instability eruption, or a jet-driven fallback SN from a Wolf–Rayet (W-R) star. The fallback scenario would naturally explain the similarity between these events and radio-loud fast transients, and suggests a picture in which most stars massive enough to undergo a W-R phase collapse directly to black holes at the end of their lives.
Hydrogen-rich Type II supernovae (SNe II) are the most frequently observed class of core-collapse SNe (CCSNe). However, most studies that analyse large samples of SNe II lack events with absolute peak magnitudes brighter than −18.5 mag at rest-frame optical wavelengths. Thanks to modern surveys, the detected number of such luminous SNe II (LSNe II) is growing. There exist several mechanisms that could produce luminous SNe II. The most popular propose either the presence of a central engine (a magnetar gradually spinning down or a black hole accreting fallback material) or the interaction of supernova ejecta with circumstellar material (CSM) that turns kinetic energy into radiation energy. In this work, we study the light curves and spectral series of a small sample of six LSNe II that show peculiarities in their H α profile, to attempt to understand the underlying powering mechanism. We favour an interaction scenario with CSM that is not dense enough to be optically thick to electron scattering on large scales – thus, no narrow emission lines are observed. This conclusion is based on the observed light curve (higher luminosity, fast decline, blue colours) and spectral features (lack of persistent narrow lines, broad H α emission, lack of H α absorption, weak, or non-existent metal lines) together with comparison to other luminous events available in the literature. We add to the growing evidence that transients powered by ejecta–CSM interaction do not necessarily display persistent narrow emission lines.
The hydrogen-poor supernova (SN) PTF11rka (z = 0.0744), reported by the Palomar Transient Factory, was observed with various telescopes starting a few days after the estimated explosion time of 2011 December 5 UT and up to 432 rest-frame days thereafter. The rising part of the light curve was monitored only in the RPTF filter band, and maximum in this band was reached ∼30 rest-frame days after the estimated explosion time. The light curve and spectra of PTF11rka are consistent with the core-collapse explosion of a ∼10 M⊙ carbon–oxygen core evolved from a progenitor of main-sequence mass 25–40 M⊙, that liberated a kinetic energy Ek≈4 × 1051 erg, expelled ∼8 M⊙ of ejecta, and synthesized ∼0.5 M⊙ of 56Ni. The photospheric spectra of PTF11rka are characterized by narrow absorption lines that point to suppression of the highest ejecta velocities (≳ 15 000 km s−1). This would be expected if the ejecta impacted a dense, clumpy circumstellar medium. This in turn caused them to lose a fraction of their energy (∼5 × 1050 erg), less than 2 per cent of which was converted into radiation that sustained the light curve before maximum brightness. This is reminiscent of the superluminous SN 2007bi, the light-curve shape and spectra of which are very similar to those of PTF11rka, although the latter is a factor of 10 less luminous and evolves faster in time. PTF11rka is in fact more similar to gamma-ray burst SNe in luminosity, although it has a lower energy and a lower Ek/Mej ratio.
Most Type I superluminous supernovae (SLSNe-I) reported to date have been identified by their high peak luminosities and spectra lacking obvious signs of hydrogen. We demonstrate that these events can be distinguished from normal-luminosity SNe (including Type Ic events) solely from their spectra over a wide range of light-curve phases. We use this distinction to select 19 SLSNe-I and four possible SLSNe-I from the Palomar Transient Factory archive (including seven previously published objects). We present 127 new spectra of these objects and combine these with 39 previously published spectra, and we use these to discuss the average spectral properties of SLSNe-I at different spectral phases. We find that Mn II most probably contributes to the ultraviolet spectral features after maximum light, and we give a detailed study of the O II features that often characterize the early-time optical spectra of SLSNe-I. We discuss the velocity distribution of O II, finding that for some SLSNe-I this can be confined to a narrow range compared to relatively large systematic velocity shifts. Mg II and Fe II favor higher velocities than O II and C II, and we briefly discuss how this may constrain power-source models. We tentatively group objects by how well they match either SN 2011ke or PTF12dam and discuss the possibility that physically distinct events may have been previously grouped together under the SLSN-I label.
Stars with zero-age main sequence masses between 140 and 260 M⊙ are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce up to several tens of solar masses of radioactive nickel, resulting in luminous transients similar to some superluminous supernovae (SLSNe). Yet, no unambiguous PISN has been discovered so far. SN 2018ibb is a hydrogen-poor SLSN at z = 0.166 that evolves extremely slowly compared to the hundreds of known SLSNe. Between mid 2018 and early 2022, we monitored its photometric and spectroscopic evolution from the UV to the near-infrared (NIR) with 2–10 m class telescopes. SN 2018ibb radiated > 3 × 1051 erg during its evolution, and its bolometric light curve reached > 2 × 1044 erg s−1 at its peak. The long-lasting rise of > 93 rest-frame days implies a long diffusion time, which requires a very high total ejected mass. The PISN mechanism naturally provides both the energy source (56Ni) and the long diffusion time. Theoretical models of PISNe make clear predictions as to their photometric and spectroscopic properties. SN 2018ibb complies with most tests on the light curves, nebular spectra and host galaxy, and potentially all tests with the interpretation we propose. Both the light curve and the spectra require 25–44 M⊙ of freshly nucleosynthesised 56Ni, pointing to the explosion of a metal-poor star with a helium core mass of 120–130 M⊙ at the time of death. This interpretation is also supported by the tentative detection of [Co II] λ 1.025 μm, which has never been observed in any other PISN candidate or SLSN before. We observe a significant excess in the blue part of the optical spectrum during the nebular phase, which is in tension with predictions of existing PISN models. However, we have compelling observational evidence for an eruptive mass-loss episode of the progenitor of SN 2018ibb shortly before the explosion, and our dataset reveals that the interaction of the SN ejecta with this oxygen-rich circumstellar material contributed to the observed emission. That may explain this specific discrepancy with PISN models. Powering by a central engine, such as a magnetar or a black hole, can be excluded with high confidence. This makes SN 2018ibb by far the best candidate for being a PISN, to date.
Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question in astrophysics. Studies of SN host galaxies have proven to be powerful in providing constraints on the progenitor populations. In this paper, we present all CCSNe detected between 2009 and 2017 by the Palomar Transient Factory. This sample includes 888 SNe of 12 distinct classes out to redshift z approximate to 1. We present the photometric properties of their host galaxies from the far-ultraviolet to the mid-infrared and model the host-galaxy spectral energy distributions to derive physical properties. The galaxy mass function of Type Ic, Ib, IIb, II, and IIn SNe ranges from 10(5) to 10(11.5) M (circle dot), probing the entire mass range of star-forming galaxies down to the least-massive star-forming galaxies known. Moreover, the galaxy mass distributions are consistent with models of star-formation-weighted mass functions. Regular CCSNe are hence direct tracers of star formation. Small but notable differences exist between some of the SN classes. Type Ib/c SNe prefer galaxies with slightly higher masses (i.e., higher metallicities) and star formation rates than Type IIb and II SNe. These differences are less pronounced than previously thought. H-poor superluminous supernovae (SLSNe) and SNe Ic-BL are scarce in galaxies above 10(10) M (circle dot). Their progenitors require environments with metallicities of < 0.4 and < 1 solar, respectively. In addition, the hosts of H-poor SLSNe are dominated by a younger stellar population than all other classes of CCSNe. Our findings corroborate the notion that low metallicity and young age play an important role in the formation of SLSN progenitors.
We present optical light curves, redshifts, and classifications for 365 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Survey. We detail improvements to the PS1 SN photometry, astrometry, and calibration that reduce the systematic uncertainties in the PS1 SN Ia distances. We combine the subset of 279 PS1 SNe Ia (0.03 < z < 0.68) with useful distance estimates of SNe Ia from the Sloan Digital Sky Survey (SDSS), SNLS, and various low-z and Hubble Space Telescope samples to form the largest combined sample of SNe Ia, consisting of a total of 1048 SNe Ia in the range of 0.01 < z < 2.3, which we call the Pantheon Sample. When combining Planck 2015 cosmic microwave background (CMB) measurements with the Pantheon SN sample, we find Omega(m) = 0.307 +/- 0.012 and w = -1.026 +/- 0.041 for the wCDM model. When the SN and CMB constraints are combined with constraints from BAO and local H-0 measurements, the analysis yields the most precise measurement of dark energy to date: w(0) = -1.007 +/- 0.089 and w(a) = -0.222 +/- 0.407 for the w(0)w(a) CDM model. Tension with a cosmological constant previously seen in an analysis of PS1 and low-z SNe has diminished after an increase of 2x in the statistics of the PS1 sample, improved calibration and photometry, and stricter light-curve quality cuts. We find that the systematic uncertainties in our measurements of dark energy are almost as large as the statistical uncertainties, primarily due to limitations of modeling the low-redshift sample. This must be addressed for future progress in using SNe Ia to measure dark energy.
Aims. We study iPTF14hls, a luminous and extraordinary long-lived Type II supernova, which lately has attracted much attention and disparate interpretation.
Methods. We have presented new optical photometry that extends the light curves up to more than three years past discovery. We also obtained optical spectroscopy over this period, and furthermore present additional space-based observations using Swift and HST.
Results. After an almost constant luminosity for hundreds of days, the later light curve of iPTF14hls finally fades and then displays a dramatic drop after about 1000 d, but the supernova is still visible at the latest epochs presented. The spectra have finally turned nebular, and our very last optical spectrum likely displays signatures from the deep and dense interior of the explosion. A high-resolution HST image highlights the complex environment of the explosion in this low-luminosity galaxy.
Conclusions. We provide a large number of additional late-time observations of iPTF14hls, which are (and will continue to be) used to assess the many different interpretations for this intriguing object. In particular, the very late (+1000 d) steep decline of the optical light curve is difficult to reconcile with the proposed central engine models. The lack of very strong X-ray emission, and the emergence of intermediate-width emission lines including [S II] that we propose originate from dense, processed material in the core of the supernova ejecta, are also key observational tests for both existing and future models.
Interaction-powered supernovae (SNe) explode within an optically thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pre-explosion outbursts, we produce forced-photometry light curves for 196 interacting SNe, mostly of Type IIn, detected by the Zwicky Transient Facility between early 2018 and 2020 June. Extensive tests demonstrate that we only expect a few false detections among the 70,000 analyzed pre-explosion images after applying quality cuts and bias corrections. We detect precursor eruptions prior to 18 Type IIn SNe and prior to the Type Ibn SN 2019uo. Precursors become brighter and more frequent in the last months before the SN and month-long outbursts brighter than magnitude -13 occur prior to 25% (5-69%, 95% confidence range) of all Type IIn SNe within the final three months before the explosion. With radiative energies of up to 10(49) erg, precursors could eject similar to 1 M of material. Nevertheless, SNe with detected precursors are not significantly more luminous than other SNe IIn, and the characteristic narrow hydrogen lines in their spectra typically originate from earlier, undetected mass-loss events. The long precursor durations require ongoing energy injection, and they could, for example, be powered by interaction or by a continuum-driven wind. Instabilities during the neon- and oxygen-burning phases are predicted to launch precursors in the final years to months before the explosion; however, the brightest precursor is 100 times more energetic than anticipated.
We study 34 Type Ic supernovae that have broad spectral features (SNe Ic-BL). This is the only SN type found in association with long-duration gamma-ray bursts (GRBs). We obtained our photometric data with the Palomar Transient Factory (PTF) and its continuation, the intermediate PTF (iPTF). This is the first large, homogeneous sample of SNe Ic-BL from an untargeted survey. Furthermore, given the high observational cadence of iPTF, most of these SNe Ic-BL were discovered soon after explosion. We present K-corrected Bgriz light curves of these SNe, obtained through photometry on template-subtracted images. We analyzed the shape of the r-band light curves, finding a correlation between the decline parameter Delta m(15) and the rise parameter Delta m-(10 ). We studied the SN colors and, based on g - r, we estimated the host-galaxy extinction for each event. Peak r-band absolute magnitudes have an average of -18.6 +/- 0.5 mag. We fit each r-band light curve with that of SN 1998bw (scaled and stretched) to derive the explosion epochs. We computed the bolometric light curves using bolometric corrections, r-band data, and g - r colors. Expansion velocities from Fen were obtained by fitting spectral templates of SNe Ic. Bolometric light curves and velocities at peak were fitted using the semianalytic Arnett model to estimate ejecta mass M-ej , explosion energy E-K and Ni-56 mass M( Ni-56) for each SN. We find average values of M-ej = 4 +/- 3 M-circle dot, E-K = (7 +/- 6) x 10(51) erg, and M( Ni-56) = 0.31 +/- 0.16 M-circle dot . The parameter distributions were compared to those presented in the literature and are overall in agreement with them. We also estimated the degree of Ni-56 mixing using scaling relations derived from hydrodynamical models and we find that all the SNe are strongly mixed. The derived explosion parameters imply that at least 21% of the progenitors of SNe Ic-BL are compatible with massive (>28 M-circle dot), possibly single stars, whereas at least 64% might come from less massive stars in close binary systems.
Context. The transient iPTF15dtg is a type-Ic supernova (SN) showing a broad light curve around maximum light, consistent with massive ejecta if we assume a radioactive-powering scenario.
Aims. We aim to study the late-time light curve of iPTF15dtg, which turned out to be extraordinarily luminous for a stripped-envelope (SE) SN, and investigate possible powering mechanisms.
Methods. We compare the observed light curves to those of other SE SNe and also to models for the (56) Co decay. We analyze and compare the spectra to nebular spectra of other SE SNe. We build a bolometric light curve and fit it with different models, including powering by radioactivity, magnetar powering, and a combination of the two.
Results. Between 150 and 750 d post-explosion, the luminosity of iPTF15dtg declined by merely two magnitudes instead of the six magnitudes expected from Co-56 decay. This is the first spectroscopically regular SE SN found to show this behavior. The model with both radioactivity and magnetar powering provides the best fit to the light curve and appears to be the most realistic powering mechanism. An alternative mechanism might be circumstellar-medium (CSM) interaction. However, the spectra of iPTF15dtg are very similar to those of other SE SNe, and do not show signs of strong CSM interaction.
Conclusions. The object iPTF15dtg is the first spectroscopically regular SE SN whose light curve displays such clear signs of a magnetar contributing to its late-time powering. Given this result, the mass of the ejecta needs to be revised to a lower value, and therefore the progenitor mass could be significantly lower than the previously estimated >35 M-circle dot.
We present observations of a peculiar hydrogen- and helium-poor stripped-envelope (SE) supernova (SN) 2020wnt, primarily in the optical and near-infrared (near-IR). Its peak absolute bolometric magnitude of −20.9 mag (Lbol, peak = (6.8 ± 0.3) × 1043 erg s−1) and a rise time of 69 days are reminiscent of hydrogen-poor superluminous SNe (SLSNe I), luminous transients potentially powered by spinning-down magnetars. Before the main peak, there is a brief peak lasting <10 days post explosion, likely caused by interaction with circumstellar medium (CSM) ejected ∼years before the SN explosion. The optical spectra near peak lack a hot continuum and O ii absorptions, which are signs of heating from a central engine; they quantitatively resemble those of radioactivity-powered hydrogen/helium-poor Type Ic SESNe. At ∼1 yr after peak, nebular spectra reveal a blue pseudo-continuum and narrow O i recombination lines associated with magnetar heating. Radio observations rule out strong CSM interactions as the dominant energy source at +266 days post peak. Near-IR observations at +200–300 days reveal carbon monoxide and dust formation, which causes a dramatic optical light-curve dip. Pair-instability explosion models predict slow light curve and spectral features incompatible with observations. SN 2020wnt is best explained as a magnetar-powered core-collapse explosion of a 28 M⊙ pre-SN star. The explosion kinetic energy is significantly larger than the magnetar energy at peak, effectively concealing the magnetar-heated inner ejecta until well after peak. SN 2020wnt falls into a continuum between normal SNe Ic and SLSNe I, and demonstrates that optical spectra at peak alone cannot rule out the presence of a central engine.
Photometric classification of supernovae (SNe) is imperative as recent and upcoming optical time-domain surveys, such as the Large Synoptic Survey Telescope (LSST), overwhelm the available resources for spectrosopic follow-up. Here we develop a range of light curve (LC) classification pipelines, trained on 513 spectroscopically classified SNe from the Pan-STARRS1 Medium-Deep Survey (PS1-MDS): 357 Type Ia, 93 Type II, 25 Type IIn, 21 Type Ibc, and 17 Type I superluminous SNe (SLSNe). We present a new parametric analytical model that can accommodate a broad range of SN LC morphologies, including those with a plateau, and fit this model to data in four PS1 filters (g(P1)r(P1)i(P1)z(P1)). We test a number of feature extraction methods, data augmentation strategies, and machine-learning algorithms to predict the class of each SN. Our best pipelines result in approximate to 90% average accuracy, approximate to 70% average purity, and approximate to 80% average completeness for all SN classes, with the highest success rates for SNe Ia and SLSNe and the lowest for SNe Ibc. Despite the greater complexity of our classification scheme, the purity of our SN Ia classification, approximate to 95%, is on par with methods developed specifically for Type Ia versus non-Type Ia binary classification. As the first of its kind, this study serves as a guide to developing and training classification algorithms for a wide range of SN types with a purely empirical training set, particularly one that is similar in its characteristics to the expected LSST main survey strategy. Future work will implement this classification pipeline on approximate to 3000 PS1/MDS LCs that lack spectroscopic classification.
Automated classification of supernovae (SNe) based on optical photometric light-curve information is essential in the upcoming era of wide-field time domain surveys, such as the Legacy Survey of Space and Time (LSST) conducted by the Rubin Observatory. Photometric classification can enable real-time identification of interesting events for extended multiwavelength follow-up, as well as archival population studies. Here we present the complete sample of 5243 SN-like light curves (in g(P1)r(P1)i(P1)z(P1)) from the Pan-STARRS1 Medium-Deep Survey (PS1-MDS). The PS1-MDS is similar to the planned LSST Wide-Fast-Deep survey in terms of cadence, filters, and depth, making this a useful training set for the community. Using this data set, we train a novel semisupervised machine learning algorithm to photometrically classify 2315 new SN-like light curves with host galaxy spectroscopic redshifts. Our algorithm consists of an RF supervised classification step and a novel unsupervised step in which we introduce a recurrent autoencoder neural network (RAENN). Our final pipeline, dubbed SuperRAENN, has an accuracy of 87% across five SN classes (Type Ia, Ibc, II, IIn, SLSN-I) and macro-averaged purity and completeness of 66% and 69%, respectively. We find the highest accuracy rates for SNe Ia and SLSNe and the lowest for SNe Ibc. Our complete spectroscopically and photometrically classified samples break down into 62.0% Type Ia (1839 objects), 19.8% Type II (553 objects), 4.8% Type IIn (136 objects), 11.7% Type Ibc (291 objects), and 1.6% Type I SLSNe (54 objects).
Context. SN 2020qlb (ZTF20abobpcb) is a hydrogen-poor superluminous supernova (SLSN-I) that is among the most luminous (maximum Mg = −22.25 mag) and that has one of the longest rise times (77 days from explosion to maximum). We estimate the total radiated energy to be > 2.1 × 1051 erg. SN 2020qlb has a well-sampled light curve that exhibits clear near and post peak undulations, a phenomenon seen in other SLSNe, whose physical origin is still unknown.
Aims. We discuss the potential power source of this immense explosion as well as the mechanisms behind its observed light curve undulations.
Methods. We analyze photospheric spectra and compare them to other SLSNe-I. We constructed the bolometric light curve using photometry from a large data set of observations from the Zwicky Transient Facility (ZTF), Liverpool Telescope (LT), and Neil Gehrels Swift Observatory and compare it with radioactive, circumstellar interaction and magnetar models. Model residuals and light curve polynomial fit residuals are analyzed to estimate the undulation timescale and amplitude. We also determine host galaxy properties based on imaging and spectroscopy data, including a detection of the [O III]λ4363, auroral line, allowing for a direct metallicity measurement.
Results. We rule out the Arnett 56Ni decay model for SN 2020qlb's light curve due to unphysical parameter results. Our most favored power source is the magnetic dipole spin-down energy deposition of a magnetar. Two to three near peak oscillations, intriguingly similar to those of SN 2015bn, were found in the magnetar model residuals with a timescale of 32 ± 6 days and an amplitude of 6% of peak luminosity. We rule out centrally located undulation sources due to timescale considerations; and we favor the result of ejecta interactions with circumstellar material (CSM) density fluctuations as the source of the undulations.
Wide-field surveys are discovering a growing number of rare transients whose physical origin is not yet well understood. Here we present optical and UV data and analysis of intermediate Palomar Transient Factory (iPTF) 16asu, a luminous, rapidly evolving, high-velocity, stripped-envelope supernova ( SN). With a rest-frame rise time of just four. days and a peak absolute magnitude of M-g = -20.4 mag, the light curve of iPTF 16asu is faster and more luminous than that of previous rapid transients. The spectra of iPTF 16asu show a featureless blue continuum near peak that develops into an SN Ic-BL spectrum on the decline. We show that while the late-time light curve could plausibly be powered by Ni-56 decay, the early emission requires a different energy source. Nondetections in the X-ray and radio strongly constrain the energy coupled to relativistic ejecta to be at most comparable to the class of low-luminosity gamma-ray bursts (GRBs). We suggest that the early emission may have been powered by either a rapidly spinning-down magnetar or by shock breakout in an extended envelope of a very energetic explosion. In either scenario a central engine is required, making iPTF 16asu an intriguing transition object between superluminous SNe, SNe Ic-BL, and low-luminosity GRBs.
SN2017egm is the closest (z = 0.03) H-poor superluminous supernova (SLSN-I) detected to date, and a rare example of an SLSN-I in a massive, metal-rich galaxy. We present the HST UV and optical spectra covering 1000-5500 angstrom, taken at + 3 day relative to the peak. Our data reveal two absorption systems at redshifts matching the host galaxy NGC 3191 (z = 0.0307) and its companion galaxy (z = 0.0299) 73 '' apart. Weakly damped Ly alpha absorption lines are detected at these two redshifts, with H I column densities of (3.0 +/- 0.8) x 10(19) and (3.7 +/- 0.9) x 10(19) cm(-2), respectively. This is an order of magnitude smaller than the H I column densities in the disks of nearby galaxies (> 10(10) M-circle dot) and suggests that SN2017egm is on the near side of NGC 3191 and has a low host extinction (E(B - V) similar to 0.007). Using unsaturated metal absorption lines, we find that the host of SN2017egm probably has a solar or higher metallicity and is unlikely to be a dwarf companion to NGC 3191. Comparison of early-time UV spectra of SN2017egm, Gaia16apd, iPTF13ajg, and PTF12dam finds that the continuum at lambda > 2800 angstrom is well fit by a blackbody, whereas the continuum at lambda < 2800 angstrom is considerably below the model. The degree of UV suppression varies from source to source, with the 1400-2800 angstrom continuum flux ratio of 1.5 for Gaia16apd and 0.4 for iPTF13ajg. This cannot be explained by the differences in magnetar power or blackbody temperature. Finally, the UV spectra reveal a common set of seven broad absorption features and their equivalent widths are similar (within a factor of 2) among the four events. |
A pigment is a colored substance that is added to materials to give it a specific color or hue. In the context of plastics, pigments are often added to provide color and enhance the aesthetic appeal of plastic products.
Pigments are derived from natural sources, such as minerals and plant extracts, or can be synthesized chemically. The majority of inorganic pigments are brighter and last longer than organic ones.
Pigments can have different effects on the physical and mechanical properties of plastics, such as tensile strength, elongation, and impact resistance. In general, the addition of pigment to plastic can decrease its overall mechanical properties due to the added weight and reduced transparency of the plastic. However, pigments can also improve the performance of plastics by adding UV stability, reducing oxidation, and enhancing chemical resistance. In addition to providing color, pigments can also be used to create special effects such as metallic or pearlescent finishes. Overall, the use of pigments in plastics is important for creating products that are visually appealing, but it must be done carefully to ensure that the desired physical and mechanical properties are not compromised.
Different products have different pigment requirements. Chemyork offers a wide range of pigments to cater to your specific needs. Whether cost-efficient options or supreme quality pigments, we have you covered.

Once people hear that someone has confessed to a crime, they typically believe that individual is guilty. After all, why would anyone admit to a crime they didn't commit?
In actuality, there are several cases of wrongful convictions based on false confessions. Many times, it's the false confession of a teenager.
The increased vulnerability of young people
Teenagers are in a unique stage of life, undergoing rapid physical and psychological changes. Their brains, particularly the prefrontal cortex responsible for decision-making and understanding consequences, are still developing. This biological fact makes them more impulsive and less able to foresee the long-term implications of their actions, which makes them vulnerable to high-pressure situations like interrogations.
Interrogation techniques can be intense and psychologically manipulative. Law enforcement aims to create a sense of hopelessness and fear in a juvenile and sometimes promises leniency in exchange for a confession. These tactics can be overwhelming for teenagers, who are naturally more susceptible to suggestions and peer pressure. Therefore, they are prime candidates for false confessions of guilt.
Being questioned in a police station can lead to panic and poor decision-making. Intimidating interrogations are designed to elicit fear and anxiety. A heightened emotional state can cloud judgment, leading to decisions not in the juvenile's best interests.
Furthermore, many teenagers lack a comprehensive understanding of their legal rights and the criminal justice process. Since they don't grasp the implications of confessing to a crime they didn't commit, they might view a confession as a quick solution to end a stressful situation, naively believing the truth will eventually prevail.
The consequences of a false confession are devastating, leading to wrongful convictions that can alter the course of a young person's life. Unfortunately, most juries fail to realize the increased likelihood of a juvenile making a false confession.
If your teenager has confessed to a crime they didn't commit, it's vital that you reach out to someone who can help mitigate the damage of a false confession. They can provide guidance and safeguard your child's rights. |
November is here, the month when we give thanks for all of our blessings - and start getting ready for the Christmas season, of course! Of the many things that you're thankful for, there's no doubt that good health is high on the list.
What better way for men to share their gratitude for good health and to raise awareness for the good health of other men than by growing out their mustaches? Have you heard the term "Movember" but weren't aware of what it was about?
What is Movember?
Well, that's exactly what Movember (or No Shave November) is all about! You have probably seen these terms on your social media newsfeed and you're wondering what it's all about. Maybe you're looking for a way to do something meaningful during the month of Thanks.
Read on to learn more about Movember, including what it is exactly, and how you can participate.
Movember Explained
In Movember, people encourage men to grow a mustache during the month of November. This annual event was the brainchild of the Movember Foundation. The Movember campaign aims to raise awareness of men's health issues, such as prostate and testicular cancer, depression, and suicide in men.
The intention of this charity event is to "change the face of men's health". The phrase is both literal and figurative. Men who don't normally have mustaches are growing them, and men who usually have mustaches are growing them even longer.
Raising Awareness - Early Detection is the Key
By encouraging men (who are dubbed "Mo Bros" or Movember Men) to take part in Movember, the charity event hopes to encourage more people to take their health seriously. It focuses on early detection and treatment for ailments that plague men. It raises hopes that the number of preventable deaths will ultimately be reduced and men can live happier and healthier lives.
In addition to annual medical check-ups, the Movember Foundation prompts men to learn about their family history of health-related issues. For example, prostate cancer and testicular cancer, depression, and anxiety. Movember also aims to help men let go of unhealthy habits and start adopting lifestyle changes that will ultimately increase their overall mental and physical health and well-being.
The Movember Foundation uses the mustache as the focal symbol of their movement, and it focuses on these primary areas:
- Testicular cancer
- Prostate cancer

The Movember Foundation was launched in 2004. That year, the charity event held events in New Zealand and Australia to raise awareness and funds for men's health-related issues, such as depression and prostate cancer.
Three years later, in 2007, Movember events expanded to Ireland, Denmark, Canada, Spain, El Salvador, the United Kingdom, Czech Republic, as well as South Africa, Israel, Taiwan, and the United States.
In 2010, the Movember Foundation and Tacheback, a UK charitable event, joined forces. Canadians topped the charts as the biggest contributors to Movember charities in 2011.
Two years later, the Movember Foundation was listed as one of the top 100 non-government organizations (NGOs).
History of Movember
In 1999, the Australian news program Seven Nightly News aired a story about a group of men from Adelaide who shared their idea for growing mustaches to raise awareness for a men's health charity for the entire month of November.
The group coined the term "Movember". The group began with 80 Adelaide men. It wasn't long after their story aired on the news that the news spread and men around the country began to participate in the charity event.
In 2004, a completely unrelated Melbourne-based group planned an event in which 30 men grew their mustaches for 30 days to raise awareness for prostate cancer and mental health (depression). The following year, almost 500 people raised the largest donation the foundation had ever received. More than $40,000 was raised for the Prostate Cancer Foundation of Australia. The group would later become the Movember Foundation Charity and received charity status in Australia.
After spreading to Europe, South Africa, and North America, the Movember Foundation has raised more than $174 million worldwide for men's health awareness and prostate cancer research.
The group was granted charity status in the US, and in 2010, American participants alone raised more than $7.5 million. In 2012, an estimated 1.1 million people signed up to participate and raised a staggering $95 million.

How Inadequate Follow-Up Treatment Can Cause Patient Harm
After seeking out diagnostic results for your health, you expect your doctor to call or contact you about your treatment options. However, you may have never received a response and assumed everything was fine. Unfortunately, when you find out later that there was a serious problem your doctor failed to follow up on, things can rapidly change.
Failure to contact you about further treatment can lead to serious health consequences. In fact, without proper treatment, many serious conditions that would have been less severe if caught earlier become much more dangerous. Unfortunately, this can lead to medical malpractice, harm, and even death for the patient. A medical malpractice attorney in Portland can help you assess your options if you or a loved one are harmed.
Inadequate Follow-Up Treatment Can Have Deadly Consequences for Patients
Inadequate follow-up treatment refers to any cases where a doctor or patient fails to follow up on treatment, diagnosis, or aftercare. When this happens, it can have extreme negative consequences for the patient. Unfortunately, some of these impacts can turn deadly.
A review published in the National Library of Medicine refers to a 20-year collection of studies on the failure to follow up on hospital patients' test results. These reviews found that 20 to 61% of hospitalized inpatients experienced a lack of follow-up care for test results. This lack of care can impact cancer diagnoses, antibiotic therapy, and urgent issues like osteoporosis.
Reviews of ongoing tests like these show that a significant number of test results and diagnoses are not being followed up on. For conditions like cancer, which can be treated in some cases if acted on early, this can turn into a deadly problem. In some cases, this becomes grounds for a medical malpractice claim.
Common Causes of Follow-Up Failures
Failure to provide follow-up care can happen for many reasons. In some cases, failure to communicate or to comply with medical instructions, whether by the doctor or the patient, can lead to issues with diagnosis and care. Below are a few of the most common examples you may face:
- The patient failed to comply with follow-up calls, appointments, and treatment
- The doctor failed to contact patients after a missed appointment
- Incomplete aftercare caused by a failure to track follow-up needs
- Failure to follow up with new medications or new diagnoses
- Failure to order lab tests or notify about test results
- Failure to communicate the urgency of the medical care needed
In some cases, communication errors or failure to comply are issues on the part of the patient. In these cases, the patient may be considered responsible for the negative outcomes they received. However, many of these cases involve failures on the part of the doctors, and that can potentially lead to a medical malpractice claim if the medical professional in question was negligent with your safety.
Seek Help When a Failure in Follow-Up Treatment Causes You Harm
If you have suffered harm from inadequate follow-up treatment, you may have grounds to pursue compensation. You should not have to accept the painful results of a medical professional who failed to do their due diligence. In fact, you may have grounds for a lawsuit.
At Paulson Coletti Trial Attorneys PC, we offer legal representation for those injured by a doctor's failure to follow up, as well as representation for families who lost a loved one for those reasons. We offer free consultations for potential clients so that we can speak about your potential medical malpractice claim and how we can help.

Looking east from Wyandotte Street, where the South Loop Park would become a landscaped green space above the highway (photo by Steve Paul)
Chicago has Millennium Park. Boston has the Rose Kennedy Greenway. New York has the long and extremely lively High Line.
Inventive urban green spaces, often reclaiming transportation-oriented dead zones and sometimes serving to heal communities formerly wounded by highway gashes, have sprouted all over. Will Kansas City join the club?
Momentum for such plans here is growing. Saving and repurposing the Buck O'Neil Bridge, as a replacement span rises beside it, remains a possibility. An old railroad bridge in the West Bottoms may yet see new life as a restaurant and entertainment complex. A downscaling of the north interstate loop from highway to boulevard would improve walkability between the downtown core and the River Market area.
And now, adding to the portfolio, a vision for a South Loop Park would better connect the heart of downtown with the Crossroads Arts District by capping a four-block stretch of canyon air above Interstate 670. The rumble of semis and passenger vehicles would be suppressed below a tree-lined refuge.
A series of public meetings has helped to gather ideas and wish lists, and a still-quiet civic fundraising campaign has begun to rake in corporate pledges to turn the vision into a reality.
What's not to like about this? Well, some negativos would say, it'd cost too much. But, as the saying goes, make no small plans. Kansas City has been on a roll. Despite the buffeting economic winds, the city has begun a new era of expansion, and I'm not just talking about the warehouse farms of Cass County and elsewhere along the outer ring of the metro area. With a new airport terminal, a riverfront soccer stadium, an apartment boom, a maybe ballpark, and, well, you're seeing the rest every day.
Another argument would go, "But why are we building a park? What about affordable housing?" My mostly under-reported response to that is, "Why can't we do both?" This is not an either-or choice. An urban park would enhance the lives of everyone. Sure, the South Loop Park would become the front yard for the luxe condo towers lining its northern edge. But a pedestrian-oriented green space with natural plantings, trails and abundant gathering areas would be open to all.
I recall talking some years ago with a principal at HNTB, the architecture and engineering firm, which had developed a downtown master plan coinciding with the ballroom expansion of the Bartle Hall convention center. There were already rumblings about capping the interstate and recapturing land that had been hijacked by the highway system, which two or three generations earlier caused the near-fatal squeezing of the city's heart. I also remember standing above the highway, probably on the McGee Street bridge, and wondering what could happen if the civic vision were large enough to imagine a connecting ground atop the highway and stretching between the newly opened Sprint Center (now T-Mobile) and the Kauffman Center, which was still under construction.
For those involved in the planning nuts and bolts, the project remained a too-costly pipe dream for nearly two decades.
Now HNTB has helped bring the plan to the forefront along with the city, the KC Port Authority, the Downtown Council and other partners. A request for proposals (RFP) could be issued as early as Sept. 1. But that's just one of presumably many milestones on the far horizon. A pool of state, federal, city and private funds still has a long way to go before reaching the estimated cost, currently about $160 million.
Project planners point to Klyde Warren Park in Dallas as a template. Built atop a short stretch of highway, it spans 5.2 acres, slightly larger than the 4.6 acres of South Loop Park. It adjoins the Dallas Museum of Art and other arts institutions and presents a variety of gathering opportunities, including an interactive fountain, though little in the way of what we'd call public art.
As I was writing this, I happened to find myself perched high above Millennium Park in Chicago. In the evening, colored lights illuminated the architect Frank Gehry's Pritzker Pavilion, a ribbony, open-air performance stage. Anish Kapoor's mirror-surfaced "Cloud Gate," popularly known as "The Bean," was, as usual, posing for pictures. The huge face of an everyday Chicagoan filled one of the towering video screens that make up the park's conceptual Crown Fountain (by Krueck + Sexton Architects and the Spanish artist Jaume Plensa).
Public preferences for South Loop seem to lean heavily toward it being a passive gathering space, rather than, say, a huge entertainment venue. This, after all, is a mere block or two south of the Power and Light District's entertainment and sports "living room," Kansas City Live! So, relative calm, reflection and chilling out in a garden setting will be the more likely mode of operation. With an ever-increasing downtown population, more public green space and quiet oases should be valued.
There are lots of reasons to get behind the South Loop project. Fresh air, tree-shade, pedestrian comfort, lunchtime exercise and attractive playground can all serve to enhance the urban experience and soften the edges around tall buildings and clanging streets.
Public art ranked high in a survey conducted by HNTB and its partners. Something on the order of Millennium Park's attractions — though let's not just pick another Bean off the shelf — could become the equivalent of hitting one out of the park.
Summertime typically brings a pause in various arts arenas, but there's always music. Perhaps you could find a theme running through the following.
JULY 8 — Take your pick: If you're skipping the Taylor Swift show at the GEHA, or whatever, stadium, maybe you could opt for the rockin', Prine-inspired Billy Bob Thornton and his band the Boxmasters the same night: knuckleheadskc.com.
JULY 19 — Probably sold out, but worth checking: Jeff Tweedy, the Wilco frontman on a solo tour, stops in Salina. stiefeltheater.org.
AUG. 17 — Undoubtedly because I've been on a Dylan jag, it feels natural to take in a show by the Wallflowers, which these days means son Jakob Dylan in the spotlight, backed by a touring band. uptowntheater.com |

Report: Biden quietly telling Mexico to curb surge of migrants
The Biden administration has been quietly urging Mexico to increase its efforts to stem the flow of Latin American migrants, according to a New York Times report Thursday.
This report came the same day that the administration announced plans to share millions of AstraZeneca COVID-19 vaccine doses with Mexico and Canada.
At Thursday's press briefing, White House press secretary Jen Psaki said the United States was planning to send 2.5 million doses of the vaccine to Mexico and 1.5 million to Canada, adding that it was "not finalized yet, but that is our aim."
During a video call this month with Mexican President Andrés Manuel López Obrador, President Joe Biden asked him whether more could be done to help solve the problem of the migrant surge at the border, Mexican officials and another person briefed on the conversation told The Times.

The pair also discussed the possibility of the U.S. sending Mexico some of its extra vaccine doses, a senior Mexican official told the newspaper. Mexico has publicly asked the Biden administration to send it doses of the AstraZeneca vaccine.
"Both governments cooperate on the basis of an orderly, safe and regular migration system," Roberto Velasco, director general for the North America region at Mexico's foreign ministry, said in a statement, referring to the engagement between the two countries on migration and vaccines, according to The Times.
However, Velasco said there was no quid pro quo for vaccines: "These are two separate issues, as we look for a more humane migratory system and enhanced cooperation against COVID-19, for the benefit of our two countries and the region."

A Biden administration official declined to comment on discussions with Mexico, but noted to The Times that both countries shared a common goal of reducing migration by addressing its root causes, and said they were working closely to restrict the flow of migrants to the border.
Mexico has agreed to boost its presence on its southern border with Guatemala to impede migration from Central America, one of the government officials said, according to the newspaper. Local Mexican officials too, The Times reported, say their country has lately increased efforts to stop migrants on the northern border with the U.S. also.

As The Times noted, there were indications that Mexico's commitment to stopping migrants might have decreased in the final months of the Trump administration, who would threaten tariffs against Mexican products unless the country acted more to stem the flow of migrants.
Between October and December of last year, the number of Central Americans detained by Mexico dipped, while arrests by the U.S. rose, according to Mexican government numbers and data gathered by The Washington Office on Latin America, a research organization that promotes human rights.
"The likelihood of the outgoing Trump administration threatening tariffs again was low, so there was an incentive for Mexico to go back to its default state of low apprehensions," said Adam Isacson, a border security expert at The Washington Office on Latin America, according to The Times.

GOP bill proposes extra measures to ensure noncitizens are unable to vote in federal elections
GOP members of both the U.S. House and Senate introduced a bill to add safeguards to ensure that non U.S. citizens who are already prohibited from voting in federal elections, do not do so. The bill seeks to amend the National Voter Registration Act to require documentary proof of United States citizenship to register to vote.
The Center Square reports that It would require states to obtain proof of citizenship – in person – when registering an individual to vote. Applicants would have to provide proof of citizenship when they register to vote in person, when applying for a motor vehicle license, and when applying to vote by mail. The bill lists accepted citizenship documentation and requirements for voter registration agencies.
U.S. Rep. Chip Roy, R-Texas, led a coalition of 49 Republicans to introduce the Safeguard American Voter Eligibility (SAVE) Act in the U.S. House. U.S. Sen. Mike Lee of Utah, with several cosponsors, introduced the same bill in the Senate.
Citing the border crisis and the greatest number of foreign nationals illegally entering the country in U.S. history, the measure's supporters expressed alarm that instead of being deported, many are being registered to vote.
"There is currently an unprecedented and a clear and present danger to the integrity of our election system," House Speaker Mike Johnson said. "And that is the threat of non-citizens and illegal aliens voting in our elections. In the last five and a half months or so, I've been to over 101 cities doing events all around the country in more than half the states. The first or second question that I'm asked in every public forum is about election security. Americans are deeply concerned about this. And it doesn't matter where you live or whether you're in a blue state or a red state, everyone's concerned."
Johnson blamed President Joe Biden and his administration's policies for for what he described as widespread concern about election integrity.
"… we now have so many non-citizens in the country that if only one out of 100 of those voted, they would cast hundreds of thousands of votes," the speaker added. "And since our elections are so razor thin in these days that we're in, just a few precincts in a few states decide the makeup of Congress and who is elected to the White House. This is a dangerously high number, and it's a great concern to millions and millions of Americans. It could obviously change the outcome of our elections, and this is not an empty threat or concern."
It is already a federal crime for non-citizens to vote in a federal election. Despite this, Johnson said, "no current mechanism to ensure only those registering or voting are actually citizens. … If a nefarious actor wants to intervene in our elections, all they have to do is check a box on a form and sign their name. That's it. That's all that's required. And there's a very small chance that illegal would get caught [because] states do not have the election infrastructure in place to confirm what they've said."
Johnson said noncitizens "can simply go to their local welfare office or the DMV and register to vote there," adding that "states are currently prohibited from asking someone to prove that they're a citizen when they use the federal voter registration form."
He also gave examples of "a growing number of localities" that are "blurring the lines for non-citizens by allowing them to vote in municipal local elections.
"You might not know this, but non-citizens are voting," he warned Americans. "Democrats have expressed a desire to turn on citizens and voters. That's what this open border has been all about."
Roy said the proposed SAVE Act "would thwart Democrat efforts to cement one-party rule by upholding and strengthening current law that permits only U.S. citizens to vote in Federal elections."
Lee said the bill should "pass right away" and unanimously in both houses of Congress. "The only reason to oppose this … would be if you want noncitizens to vote."
It also would create a new program requiring the Department of Homeland Security and Social Security Administration to share information with state registration systems. States would be required to identify noncitizens attempting to register to vote by accessing data in DHS' Systematic Alien Verification for Entitlements program and the SSA's Social Security Number Verification Service. The information would be compared with data from state agencies that supply state identification cards or driver's licenses.
The bill also would require states to remove non-citizens from existing voter rolls and increases federal penalties for those who register non-citizens to vote in federal elections.
Illegal immigrants are being registered to vote across America.
My SAVE Act will stop it.

"Run, run, as fast as you can. You can't catch me, I'm the Gingerbread Man," chimes the most famous of storybook cookie characters. However, the gingerbread man in Cook's sophisticated take is an irascible ice-cream truck driver just trying to get through the day in a slightly grittier fantasy world. The children in this story are presented as funny animals—little cats, raccoons, pigs, sheep and bears—and they wheedle the Gingerbread Ice Cream Man into buying them a carton of cigarettes, getting him into trouble with the law. A riotous car and helicopter chase follows, including flying ice cream bars, multiple car crashes and a shoot-out with the Big Bad Wolf. Cook (who writes for a small daily newspaper in Gloucester, Mass.) loosely bases his story on the traditional Gingerbread Man folktale, taking the character's already shaky moral status in fabledom and running with it, so to speak. His book updates the character, making the Gingerbread Man an outlaw, an antihero worthy of the celebrity-worship of adolescent girls. His black-and-white drawings feature lots of playful curves, and elaborate hand-lettering that appears to have been as fun to write as it is to read. While the book evokes many pleasures of youth (Richard Scarry's picture books and the tale of Pinocchio, among them), Cook creates a grown-up fantasy world where every pleasure has its price, and just beyond sweetness lies vice.

Wikenigma - an Encyclopedia of Unknowns Wikenigma - an Encyclopedia of the Unknown
Automerization is the name given to a process in which carbon-ring chemicals tend to spontaneously transform into closely-related chemicals when heated.
The first example found was the transformation of azulene to naphthalene.
The 'reactions' involve a re-arrangement (so called 'scrambling') of the atoms in the chemicals' carbon ring.
[…] since the characterization of the automerization of naphthalene by Scott in 1977, similar atom scramblings of other aromatic hydrocarbons such as pyrene, azulene, benz[a]anthracene and even benzene have been described. While the existence of these reactions has been confirmed, the isomerization and automerization mechanisms remain unknown.
See: Wikipedia
Note: Various mechanisms have been proposed to explain the changes - some at quantum level, e.g. 'carbon tunnelling' - but none has been formally adopted.
Also see: Benzene structureplugin-autotooltip__plain plugin-autotooltip_bigBenzene structure
The benzene molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon.
Although the compound has been very extensively studied since its first isolation in 1825, its molecular dynamics - especially at temperatures below 77K when it becomes a solid - are extremely complex and its inner mechanics remain mostly unexplored.

I said "yes" – Dije "si" – that is what Sister Xiomara put on her Facebook post after her final profession, and say "yes" she did! She was filled with joy and reverence and grace as she gave her whole life to God through the Adrian Dominican Congregation.
We live in a culture that discourages long commitments. We get the message that commitments take away our freedom, but the opposite is really true. In fully committing to something we are able to give our whole selves and be who God calls us to be.
"I want to keep all my options open," some say. But for how long? While it's true that we do not want to rush into poor decisions and make drastic life choices at a young age, we can sometimes wait so long that we lose the chance to do that which would give us life. For someone called to marriage, it would be a shame to turn eighty and still be waiting for someone better to come along!
At this time of year, we celebrate Mary's "yes" that brought forth Jesus – God among us. Imagine if Mary had said to Gabriel, "Well, I don't know. This isn't the best time and I'd like some alone time with Joseph before we start on a family. Can you come back in a few years?"
Sometimes we take that leap and say "yes" even when everything is not sure – because it never is. We cannot know the future, but we can be sure that Emmanuel – God with us – is always there on this journey of life.
Christmas blessings to all!
Sister Lorraine
More than simply making a decision, spiritual discernment is decision-making that is rooted in self-knowledge as well as a deep awareness of God's loving presence and action in our lives. Because we know God as our creator and redeemer, we lean on that graced friendship with God to help us make a good and life-giving decision.
There are many tried-and-true tools that help us prepare the soil for a fruitful discernment process. First, we need to define prayerfully the issue for discernment. It is helpful to focus our issue carefully enough to be able to state it in the form of a question that can be answered yes or no. So for example, rather than ask a more general question like, "What shall I do with my life?" we can fine-tune the question to ask something more specific like, "Will I apply to become a sister with the Adrian Dominicans?" Once the decision before us is well defined, we need to apply the tool of fact-finding. What kinds of relevant data do we need in order to make an informed decision? Once all of the facts are gathered, we can begin to assess and evaluate the data. In this process, we stay attentive to all of the thoughts and feelings that arise as we consider the different dimensions of our decision. The tool of journal keeping is helpful here.
Another handy tool in the toolbox of discernment is dialogue with others. We need to share the different aspects of our decision with the wisdom figures in our life, those who know us well and care deeply about our well-being. Equally important is the tool of solitude, where we invite God into our decision-making process. We need to confide in God our hopes, dreams, expectations, doubts, and fears. We then listen carefully to how God responds to us. A good spiritual director can help us in this discernment process.
Dominican Sister Cathy Arnold shared a useful tool of imagination that she used in discerning her call to religious life. Her spiritual director advised her to imagine herself in each choice for two weeks. So for two weeks, she lived as if she had made the decision to become a Dominican Sister. She reflected on how she felt when she woke up in the morning. What were her thoughts and feelings throughout the two weeks? Then she reversed the process and lived as if she had made the opposite decision. How did she feel? Was she relieved or devastated by the change? Click on the following link to hear Sister Cathy's discussion on discernment: https://www.youtube.com/watch?v=WwWPM4QtGwY.
Finally, how do we know that our choice represents God's deepest desires for us? Signs of validation include feelings of inner peace and joy with our decision, as well as the confirmation of the others who have shared in our discernment process.
Are you discerning an important life decision? What are your tools for the discernment process?
Blessings, Sister Sara
The hidden assumptions we hold when we begin to discern an important decision can easily derail a healthy life choice. If we automatically assume that certain options are undesirable, unthinkable, or impossible to attain, we will rule them out before we even consider our course of action. Detecting and assessing our hidden assumptions can open the way to finding God's call in our lives through our concrete decisions.
When I was in my early twenties, I assumed that following God's will for my life had to involve doing something explicitly religious. I wanted to pursue doctoral studies in European history with the hopes of becoming a college professor. In prayer, I shared my doubts with God; how could studying history possibly draw me closer to Christ or be an expression of discipleship? God, however, seemed to be affirming my desire for studies. I earned a scholarship that paid for my education, and although I never became a historian, I gained a wealth of research and writing skills. These newly acquired skills served me well as I later earned my doctoral degree in theology and became a university professor. I learned through this experience that following God's will has a diversity of forms and need not only occur in a religious context.
Often our hidden assumptions show up in what surprises us or make us resistant or defensive. When I was a member of the Covenant House lay community in New York City, again in my twenties, I was asked to consider going to Fort Lauderdale, Florida to help open a Covenant House there. At first, I was totally against the idea. As a Vermonter, who loves the four seasons, my thought was, "I won't be caught dead in Florida." Dare I say that I warmed up to the idea, and took the assignment? In the end, I loved my time there. In fact, had I not gone to Florida, I probably would not have met the Adrian Dominican Sisters and become a Dominican sister. Only by letting go of my hidden assumption that God's will must unfold in my preferred climate and geographic location, was I able to embrace God's deepest desire for me.
What have been some of your hidden assumptions when discerning God's call? Where have you not wanted to listen? How has God surprised you?
In this week between Thanksgiving and Advent, I thought I would share with you part of a Thanksgiving reflection given by our Sister Maria Goretti Browne, OP, that focuses on the sometimes hard work of practicing gratitude. Suffering is an unavoidable part of life and at times we need to lament and share our grief with others and with God. By embracing suffering in this way we can grow in our ability to love life unconditionally.
Sometimes, however, we may choose to intensify the difficulties of life by incessant complaining, stirring up resentments, nursing grudges and basically being a walking wet blanket. There is another more healthy option: gratitude. Research tells us that if we learn how to appreciate life in all its dimensions, we will feel better, be less prone to stress and sickness, sleep better, and live longer and healthier lives.
Sister Maria Goretti challenges us to give thanks in all circumstances of life. She recounts a rather extreme response of giving gratitude in the unbearable circumstances of war. She writes:
I read one time that during the war in Southeast Asia, there was a young Vietnamese boy who would sing as he worked in the rice fields, even as the bombs burst all around him. He explained that he could not stop the war, but he could keep the fear of death from overtaking his heart; he had to fight to be peaceful and happy inside while the horror and sadness of war swirled around him.
Maybe gratitude is an attitude. Most of us take very good care of our bodies, even try to walk – what is it – 10,000 steps? We practice each day, and eventually we will get to the 10,000 number. How about us practicing gratitude – Each day being more grateful than the day before, being more and more conscious of the blessings in our lives. Just look around. Thank God for our vocation, be it religious life, or married life, or single life; we are blessed with wonderful spouses or companions, wonderful co-workers, blessed with beautiful families, blessed with talents too many to enumerate, blessed with the ability to spread God's love. Everywhere we look we see where we can spread that love and gratitude.
We know the account in Scripture of the three young men who were thrown into a fiery furnace. What's the first thing they did? They broke into a song of praise and thanksgiving for all that God had made. Theirs was such an attitude of gratitude that their suffering was secondary. They danced among the flames unharmed (Daniel 3).
What about us? Do we find ways to give thanks to God in all circumstances?
The feast of Thanksgiving with family and friends ushers in the Advent season when Christians begin our preparations for the celebration of Christ's birth in our world. This spirited season proclaims the awesome mystery that, in Jesus Christ, God became one of us and found a home in our midst.
Jesus, who in his very being houses divinity, calls us to do the same: to be the presence and action of God for our world. In fact, Jesus tells us that if we follow God's love commands, God will dwell in our hearts in intimate communion. God's loving presence actually takes up residence in the inner recesses of our being.
Can you imagine what God's home in us would look like? God's home would have walls of welcome, solid floors of fidelity with plush carpets of compassion. There would be high ceilings of inclusivity and wide windows letting in nature's beauty and the multi-faceted light of wisdom. The furniture would circle around a fireplace of forgiving warmth. There would be chairs of charity, couches of consolation, sofas of serenity, and tables of tender togetherness. And, like in every godly home, there would be bookcases full of challenge, new learning, and adventurous opportunities.
In our world so wracked by ruinous hatred, violence, and despair, we must do everything in our power to safeguard God's home in our hearts. As Thanksgiving gives way to Advent's approach, what actions do you need to take to nurture God's dwelling place within you?
Centering prayer is an ancient prayer of inner awakening to divine presence in the silence of our being. In this prayer we gently let go of our thoughts, feelings, and anxious planning, and sink into that open space within ourselves where God dwells in hidden closeness. When I practice this prayer I feel somehow free from my personal story. I sense a joy in knowing that God's presence extends far beyond my thoughts, feelings, and achievements, and resides in the depths of my soul soaring into eternity. This awareness of union with God is at the heart of the spiritual life.
How can sitting in the silence of centering prayer help us to respond effectively to various life situations? Clearly, we are not deliberating on our problems and searching for solid solutions during this prayer of silence. Centering prayer, however, trains us to separate from our thoughts and feelings and to wait for God's wisdom and guidance rather than jumping to easy answers prematurely. As Albert Einstein once said, "no problem can be solved from the same consciousness that created it." By learning to orient ourselves toward God in centering prayer, we learn to see our life situations from a new divine perspective. The direction we need to go becomes clear and we are emboldened to take loving action for the betterment of those around us.
In responding to life situations, is anger helpful or is it self-defeating? Anger can be useful because it alerts us to a problem and motivates us to make change in ourselves or in our world. Twelve-step groups, for example, talk about people needing to feel the frustration of "hitting rock bottom" before they turn their lives over to God in the recovery process. Likewise, anger in the face of social injustice can move us to take collaborative action on behalf of the common good. The Adrian Dominican Sisters Vision Statement states, "impelled by the Gospel and outraged by the injustices of our day, [we] seek truth; make peace; reverence life."
While anger can serve a positive function in our lives, it can also be self-defeating. Unlike our positive emotions like affection, awe, and joy, anger feels bad and separates us from others. Our inability to handle anger effectively can entrap us in hostility, hatred, and despair. Caught in the volatility of anger, we react with revenge and retaliation against ourselves and others. Interestingly, our interpretation of events can create more anger than the event itself. Here is one example of how it can play out in community life.
I begin with the following premise: if I am a good and loving Sister, the Sisters with whom I live will love me in the ways in which I want to be loved. All is well, until one day I experience what appears to be a rejection by one of my Sisters. Feeling upset, I begin to draw out different meanings from the event that only stoke my anger. I might conclude that I am an unlovable community member who caused or deserves this hurtful treatment. I might also decide that the other Sister is a messed up, dysfunctional person because she is not meeting my ideals. Underneath my anger is the fear of losing self-esteem.
My interpretations of the event are invalid because blaming myself for the other person's actions is diminishing my self-esteem. Making a monster out of the other person and blaming them for causing my hurt blinds me to the good in the other person and hardens my heart toward them.
Empathy, the ability to understand accurately the thoughts and motives of others, is the best remedy for anger. If I can put myself in the other person's place and see their struggle, I will have more compassion toward them. I can talk with them about why they did what they did. The fact that they treated me poorly does not mean that I am unlovable or less of a person. I no longer see myself as responsible for their actions and my self-esteem increases. I take responsibility for my own feelings and practice self-compassion. I am now in a place of calm to work through the problem with my Sister.
We need to discern the message of anger by taking quiet time to blow off steam and work through our thoughts and feelings. We need to be willing to do the inner work it takes to have healthy and happy relationships. How have you dealt with anger in your life?
In this week of All Saints and All Souls, we remember the people in our lives that have helped to build our character and shape our sense of Christian discipleship. These special people have been the face of God for us.
I grew up next door to my grandparents on their farm in Vermont. When I was a little girl my twin sister, Sandy, and I would run up the road to visit them. No matter when we came, Grammy and Gramp were always so happy to see us.
Gramp was a tall, slender man. He was not a great dresser. He wore tan, baggy pants, plaid flannel shirts, and big work boots. He sported an old red cap on the back of his head, which was always slightly tilted to one side. He had twinkling eyes and a big arching nose over an equally big grin.
Gramp loved to spend time with us. He would harness his big white workhorse and take us with him into the fields and forests. It was his delight to share with us the wonders of his world! He would point out the wildflowers and tell us the names of all the trees. He was a great storyteller, and there was always a moral to the story. One of his favorite themes was the importance of resourcefulness and creativity. He would say to us, "What if you are out working in the woods with the horse and the harness broke? What could you do?" Seeing our bewilderment, he would explain, "Well, you could look for some tree vines, like this princess pine, braid them together and use it to repair the harness."
When I was about 4 or 5 years old I wanted to help Gramp with his farming. His response to me was always, "Of course, you are just the girl who can do it." I felt like I could do anything.
That spring I wanted to help him plant the potato crop. The problem was that potatoes had to be planted a specified distance apart. For some varieties it's 10 inches apart, others 8 inches. But for a 5- year-old getting the potatoes the right distance apart seemed like an impossible task. So my grandfather cut a stick the right length and all I had to do was put a potato at each end of the stick — stick potato, stick potato. I probably only planted one row of potatoes that whole day, but I felt included in all the good work that was happening in my family.
My favorite thing to do was to drive the horse and wagon. Now Gramp had taught me how to hold the reigns and steer the horse. When we would get into the driveway in front of the barn, he taught me how to make a big sweeping turn so that the wagon would end up in front of the barn door. However I did it, he would say, "I couldn't have done it better myself."
When my sister and I would leave my grandparents, their constant refrain was, "Come again."
Gramp said to us, "When we are not together, and I see the two of you playing, and I am in a distant field, I will call out, "I, YI, YI, YI, YIIII! And you will know that I see you and that I love you."
Who are the ordinary saints in your life?
How we handle criticism affects our capacity to discern the workings of the Holy Spirit in the ups and downs of our everyday life. If we can learn to befriend our critics, we will discover that they are actually our best teachers in the process of becoming a mature follower of Christ. Growth in the spiritual life requires self-knowledge, humility, and trust in God's unconditional love whether our behavior happens to be right or wrong. So what is your experience of dealing with criticism?
In his book, Feeling Good, cognitive therapist Dr. Dave Burns describes three possible responses to critique, which he calls: "sad, mad, or glad."* If you go the sad route, you will automatically conclude that the critic is correct. You never take time to explore what actually happened. Instead, you jump to the conclusion that you were wrong. You magnify and personalize the negative message. "I'm always screwing up. I'm a complete failure." Because you live with the expectation that you should be perfect, you assume that your mistake means that you are worthless. As a result, you will experience sadness, anxiety and diminished self-esteem. Your response will be ineffectual, as you withdraw in isolation and avoidance.
If you go the mad route, you will defend yourself against the ravages of imperfection by attempting to persuade your critic that they are the problem. You refuse to admit even the possibility that you could have made a mistake, that you are less than perfect, because to do so means admitting that you are worthless. Ready for a fight, you attack your critic with fierce accusations. In the heat of the battle, you may feel emboldened by your self-righteous indignation. But when it's over, your response will also be self-defeating because you have done irreparable damage to the relationship.
If you go the glad route, you will need enough self-esteem to accept yourselves with all of your imperfections. When under critique, your first response is inquiry. You ask yourself: "Is there any truth to the criticism?" Having taken the time to prayerfully investigate the situation, you are now prepared to offer a solution. If compromise is called for, you can negotiate. If you were mistaken, you can offer an apology, if appropriate, and then make the necessary amends to address the problem. If your critic was wrong, you can find a way to address this reality in a respectful fashion. This response will enhance your sense of competence because you have handled the situation in a way that respects your own integrity and that of others.
Take some time this week and explore your experience of handling criticism. What have you learned?

Understanding Chiropractic Care: Chiropractic care is a healthcare discipline focused on the diagnosis and treatment of musculoskeletal disorders, primarily through manual adjustments and manipulations of the spine. However, its benefits extend beyond just alleviating pain. Chiropractors emphasize the body's inherent ability to heal itself and aim to restore proper alignment and function to the musculoskeletal system.
Promoting Mobility and Functionality: For the elderly, maintaining mobility and functionality is crucial for independent living. Age-related changes, such as decreased bone density and muscle mass, can lead to issues like joint stiffness and reduced range of motion. Chiropractic adjustments can help address these issues by realigning the spine and improving joint mobility. By restoring proper spinal alignment, chiropractic care can alleviate restrictions that hinder movement, allowing seniors to perform daily activities with greater ease and confidence.
Pain Management: Chronic pain is a common challenge faced by many older adults and can significantly impact their quality of life. Whether it's due to arthritis, degenerative disc disease, or other musculoskeletal conditions, managing pain is essential for promoting independence. Chiropractic treatments offer a drug-free alternative for pain management. Through targeted adjustments and manipulations, chiropractors can reduce pain levels, improve function, and enhance overall well-being, enabling seniors to remain active and engaged in their daily lives.
Preventing Falls and Injuries: Falls are a leading cause of injury and loss of independence among the elderly. Balance issues, reduced muscle strength, and impaired mobility increase the risk of falls in older adults. Chiropractic care can play a vital role in fall prevention by addressing underlying musculoskeletal imbalances and enhancing proprioception—the body's awareness of its position in space. By improving spinal alignment and mobility, chiropractic adjustments can help seniors maintain better balance and coordination, reducing their risk of falls and related injuries.
Enhancing Overall Health and Well-being: Chiropractic care focuses on optimizing the body's natural healing mechanisms, which can have far-reaching benefits for seniors' overall health and well-being. By improving spinal function and nervous system communication, chiropractic treatments can boost immune function, enhance organ function, and support better sleep quality. Additionally, many seniors report feeling more energetic and mentally alert after chiropractic adjustments, which can contribute to a greater sense of independence and vitality.
Complementary Approach to Geriatric Care: Chiropractic care is not meant to replace traditional medical interventions but rather complement them. Many older adults receive chiropractic treatments alongside conventional medical care to address a wide range of health concerns. Chiropractors often collaborate with other healthcare professionals, such as primary care physicians and physical therapists, to provide comprehensive care tailored to the individual needs of elderly patients. This multidisciplinary approach ensures that seniors receive the most effective and appropriate treatments for their specific conditions, ultimately supporting their independence and quality of life.
Tailored Treatment Plans: One of the strengths of chiropractic care is its emphasis on personalized treatment plans. Chiropractors take into account each patient's unique health history, mobility challenges, and lifestyle factors when designing treatment protocols. For elderly patients, this means receiving care that is tailored to their specific needs and goals. Whether it's addressing chronic pain, improving mobility, or preventing falls, chiropractors work closely with seniors to develop strategies that promote independence and long-term wellness.
In an aging population, maintaining independence and quality of life becomes increasingly important for older adults. Chiropractic care offers a holistic approach to promoting independent living by addressing musculoskeletal issues, managing pain, preventing falls, and enhancing overall well-being. By incorporating chiropractic treatments into their healthcare regimen, elderly individuals can enjoy greater mobility, functionality, and vitality, allowing them to live life to the fullest for years to come. |

Speaker 1 (00:00):
Let's bring in transportation Secretary Pete Buttigieg. Secretary, good to see you. Thanks for being here. What steps is the administration and specifically the transportation department taking right now to fix things on the ground?
Pete Buttigieg (00:15):
There are several things that we're working on, even while we continue to respect the work of the independent NTSB, the National Transportation Safety Board, which for good reason is independent for my department, is leading the safety investigation and it'll take a while for their report to come through, but we don't have to wait for that report in order to take certain steps that we are calling for and taking right now. Today we're pushing a three part drive on rail safety. Things we are doing as an agency, things we're asking Congress to do to support us and things we're saying need to change in the rail industry. I'll give you a couple examples. We are continuing to drive forward on a rule that will require minimum staffing on trains at a time when the rail industry has been pushing to be allowed to have as few as one person, even on trains that can run a mile long or longer. At a minimum, there need to be two. That's something that we're working on through the regulatory process.
A second thing is that I've directed the Federal Rail Administration to conduct a stepped up, focused inspection program on routes that are carrying certain kinds of hazardous materials. We need to work on the bigger picture, too. That's where I'm calling Congress in to do things like raising the cap on fines so we can better hold rail companies accountable when there are violations.
Speaker 1 (01:28):
But is there anything that the transportation department could have done sooner to avoid this from happening in the first place?
Pete Buttigieg (01:36):
Well, our personnel were on the ground with an hours of this incident, but I do think that every rail incident calls the question on how we can strengthen the regulation of rail safety in this country. Now, that is something that the rail industry has fought, but that we have been raising the bar on since we got here and will continue to do. Look, whether it's the crew staffing rule or whether it's the regulations around the strength of the tanks containing the material that transits, again, I'm not going to get ahead of the NTSB'S finding on some of the specific root causes in this incident, but we know enough to know that it's long past time to continue the work of raising the bar on rail safety. We're continuing our work on that. We're asking Congress, especially since there seems to be some newfound bipartisan interest in doing something, to untie our hands and make it possible for us to do more.
Speaker 1 (02:26):
What about the rail companies themselves? Specifically in this in instance, how are you holding this rail company accountable?
Pete Buttigieg (02:34):
Well, first of all, we're going to hold them accountable to the fullest extent of the law on any violations from Norfolk Southern that contributed to this disaster. Meanwhile, the EPA is holding them responsible for the cleanup. I know the EPA administrator, Michael Regan has been on the ground today emphasizing just that. But one of the reasons that I'm asking Congress for help is that right now there is a cap on the toughest fines that we can impose, about a quarter of a million dollars per violation. When you're thinking about multi-billion dollar freight rail companies, I don't think that is enough to have the deterrent effect that we need as a regulator. One of many areas where I'm asking Congress to stand up, frankly, to the rail industry and go the extra mile to help us put more strength in our toolbox.
Speaker 1 (03:20):
Did they actually break safety protocols here?
Pete Buttigieg (03:24):
That again, it is the outcome of an investigation, and I'm not going to get ahead of the results of that investigation. What I will say is that Norfolk Southern is a multi-billion dollar railroad company that has stood with its peers to push back on regulation after regulation to try to water down, weaken, or in some cases remove important rail safety rules, and too often they get their way. I think that the rail industry needs to move immediately to take certain steps like protect whistleblowers in the industry. That's something that they could sign up for today. We have a program that would make that possible. They need to proactively let states know when they're coming through with hazardous materials. They need to finish the job and get sick leave to their workers because a healthy workforce is a safe workforce. We're going to continue pressing ahead on formal requirements and regulations. I'm asking Congress to push ahead on rules, but industries shouldn't wait for us to force them to do the right thing.
Speaker 1 (04:20):
You have said that you would visit East Palestine when the time is right, but it's been two weeks since this derailment. When is the time right?
Pete Buttigieg (04:29):
I'm planning to go and when I do, it will be focused on action, not on politics, not on show. In the early days, I have been respecting the role that the independent NTSB plays and staying out of their way, but we are now entering the policy phase of our response to this. Even as NTSB continues finalizing their work, this is the right time for us to be looking at immediate steps from USDOT.
Speaker 1 (04:53):
But sir, you ran for president. You understand politics better than most, and you know the importance of showing up. Why not go sooner to show people on the ground the efforts being made by the administration?
Pete Buttigieg (05:06):
Well, again, the administration was on the ground from day one. I have followed the normal practice of transportation secretaries in the early days after a crash, allowing NTSB to lead the safety work and staying out their way. But I am very eager to have conversations with people in East Palestine about how this has impacted them. Again, when I'm there, the focus is going to be on results. It's going to be on work that needs to be done. Because one thing I saw as a mayor dealing with multiple disasters is that there's two kinds of people who show up in the aftermath of a disaster. People who are there because they have a specific role to play and they're there to play their role, and do the work, and help the community. People are there because they want to be seen being there and they want to look good when I'm there, it's going to be about action.
Speaker 1 (05:48):
But we have heard from the mayor, we've heard from residents that want to see representation on the ground. They think that that's important. Can you give us any sort of timeline about when you may visit?
Pete Buttigieg (05:59):
USDOT representation on the ground began within hours of the incident, and I'm looking forward to getting there as well while respecting the independent role of the NTSB.
Speaker 1 (06:09):
Do you think the President should visit?
Pete Buttigieg (06:11):
Look, right now I'm focused on making sure that we have the tools that are needed on the ground to respond to this. You've got EPA there, you've got our department supporting the NTSBs work there. You've got the CDC, Health and Human Services there to look after the health side, and we've got to make sure that that agency response continues. I know the President cares a lot about what's happening there. He's spoken to me about it and we are going to continue doing everything we can to make sure this community is not left behind.
Speaker 1 (06:41):
What do you think of the former president visiting there tomorrow?
Pete Buttigieg (06:45):
Look, I don't know exactly what he's planning to do there, especially since his administration was anti-regulation and pro-industry every step of the way. There are a number of cases where regulations, including safety regulations and regulations that are related to rail, were either watered down or frozen in place by his administration. But I don't know what he's planning to do there. I do know that we have work to do that we've been underway on from day one of this situation. While the politics will come and go and the grandstanding will come and go, we will be there for the long haul to make sure that this community is supported, and to make sure that there's more accountability for the railroad industry in this country.
Speaker 1 (07:27):
Are you confident in the nation's railways at this point?
Pete Buttigieg (07:31):
Well, what I'll say is there's been enormous progress, but there's a long way to go. Derailments are about half of what they were at at the beginning of this century, but until there are zero, I'm not satisfied. We have more work to do as a country. We're doing more work as a department, and I'm calling on congress to act and rail industry to get out of the way.
Speaker 1 (07:51):
Just in recent months, we've seen recent air traffic control systems meltdown. We've had a few near collisions at airports. We've had this trained derailment. Prior to the infrastructure bill, we were seeing bridges collapsing. What do you say to Americans who say that they're just not sure it's safe to move around freely around this country right now? Is the administration really meeting Americans where they are on these issues?
Pete Buttigieg (08:14):
This is one of the reasons we fought so hard to get infrastructure funding. You saw bridges collapsing in the United States of America, and decades of underinvestment catching up to us. We are making the investment that is long overdue in our infrastructure in order to maintain safety, just as we are working to maintain safety in the aviation system. A remarkable fact that a form of transportation that involves flying through the air nearly at the speed of sound has the safety record that it does, where in most recent years, there have been zero passenger fatalities on airlines. But we have a lot of work to do. There's more to do on rail. I am particularly concerned about roadway safety in this country, which often gets less attention, but claims 40,000 lives a year. We can't treat that as normal or as the cost of doing business. That's why whether we're talking about road, rail, air or any other form of transportation, we are squarely focused on safety in the US Department of Transportation. We always will be.
Speaker 1 (09:10):
I just have to ask, because it did take you a couple of days to respond publicly, or several days to respond publicly to this particular incident, do you wish you would've spoken out sooner?
Pete Buttigieg (09:20):
Yes. I was focused on just making sure that our folks on the ground were all set, but could have spoken sooner about how strongly I felt about this incident. That's a lesson learned from me.
Speaker 1 (09:31):
All right, Mr. Secretary, thank you for that. Of course, we are thinking about everybody on the ground in East Palestine. We appreciate your time.
Pete Buttigieg (09:38):
Thank you. Take care.

What is another word for
lock washer
Pronunciation: [lˈɒk wˈɒʃə] (IPA)
A lock washer is a vital component in keeping bolts and nuts securely in place. There are various types of lock washers available, such as split washers, toothed washers, and external tooth lock washers. Split washers, also known as helical spring washers, feature a split in the washer's circumference that allows it to compress when bolted. Toothed washers or internal tooth lock washers have teeth on the inside that grip onto nuts and bolts to keep them from loosening. External tooth lock washers, on the other hand, have teeth on the outside that grip onto the surface to prevent the bolt or nut from loosening. Understanding the different types of lock washers is crucial to ensure the right one is used in various applications.

The Dolomites: Mountains for Everyone
Anyone who loves nature will find something in the Dolomites that is different from other mountain areas in the world.
Marvelous peaks emerge from green alpine meadows and vast forests of spruce and larch. The peaks change color constantly as the sun rises and travels across the sky during the day. You can admire many shades of pink and red in the sunrise and later the burning reds of the sunset. Well-marked trails allow excursionists to move around without any problem and enjoy views of peerless beauty.
In the Dolomites, not only skilled climbers can reach the top of the mountains. On these peaks, there are some routes called "Via Ferrata", well supplied with steel wires, ladders, and hanging bridges. These routes travel over many old paths that have survived since the First World War when Italian and Austrian soldiers, fighting here, marked them out.
A well-trained excursionist provided with a climbing harness, helmet, carabiner, and Ferrata lanyard, can climb these routes very safely and without needing complete climbing equipment or a partner. At the beginning of the season, some Ferrata routes are not practicable, because there is still snow up in the mountains. Check via Ferrata accessibility.
In the Dolomites, there is a rich tradition of Alpine climbing. Many of the great routes of the Alps are to be found here and the area continues to be the home of some very strong and talented climbers.
The Dolomites are a climber's paradise. There are routes here of every grade and length and every climber, from beginner to expert, will find something to match his abilities and ambitions here.
You could choose either to do an 8c+ single pitch on a crag or to do a 200-meter, grade III route on Torri del Sella.
On the Tofane there are some great lines from 400 to 900 meters in length; there are well-known modern routes of 1000 meters or more on the sunny and solid south face of the Marmolada or the scary north face of the Civetta. There are the huge overhangs on the Tre Cime di Lavaredo; and the never-ending 1600 meters of north Arete on the Agner. The choice is massive.
Most routes can be climbed in a day by leaving in the early morning from your hotel or campsite. For ascents of over 1000 meters or ones needing a long walk-in, the best option is to stay in a mountain hut. In the Dolomites, there are more than a hundred huts, famous for their hospitality and great food. All of them are warm and comfortable, and most have showers and hot water. There is a choice of 2 or 4 bedrooms or a large dormitory. You can reach most of them along a pleasant path with great views, others on cable cars or chair lifts. Only a few huts can be reached by car.
Most routes have fixed protection and this varies considerably with the type of route:
The classic routes are usually equipped with pitons, which are not always reliable (some of them are very old), and, mostly on the easiest routes, protection is often sparse. Sometimes a whole pitch has no pitons at all! Route finding requires a good level of experience, as does assessing the quality of fixed gear on the route. The quality of the rock must also be carefully evaluated.
Rock quality is not always excellent, the Dolomia can be very friable, particularly on the yellow-colored walls. The most repeated routes are usually safe because they have already been cleaned by many ascents. Most routes have fixed protection and this varies considerably with the type of route:
- The classic routes are usually equipped with pitons, which are not always reliable (some of them are very old), and, mostly on the easiest routes, protection is often sparse. Sometimes a whole pitch has no pitons at all! Route finding requires a good level of experience, as does assessing the quality of fixed gear on the route.
- The modern routes are equipped with plentiful bolts and the rock is almost always very solid. Success on these routes requires a combination of technical ability and a good level of climbing fitness and stamina. Sports routes are to be found at a large number of venues. All are well bolted and many are in beautiful surroundings.
For the classic routes, the grades are the UIAA grades, which go from I to XII+ and for aid climbing, grades from A0 to A4 are used. On the modern and sport routes the French scale is used; it goes from grade 4a to grade 9c.
There are a lot of crags also: In the Ampezzo Valley, sports climbers can find fantastic places to play, with the added value of the natural beauty of the locations of the numerous crags in this area. To get to most of them, you only have to walk for about 15 minutes. Some of them are overhanging (for example Erto) so that it is possible to climb also on rainy days.
I hope that the information given here is sufficient for you to start your journey that, I'm certain, will be an unforgettable experience.
A vacation on the Dolomites is something unique, a priceless experience that is good for both body and soul. Finally, I ask all those who may visit these valleys to respect local customs and traditions and, most of all, to respect the mountains: only this way can they give you the best of themselves, and not only your alpine experience will grow, but also your heart.

How do I know if my car registration has been cloned?
Every road-going car in the UK must have a number plate and this is unique to that particular vehicle and is used primarily as an identification method.
But though it might be unique to a particular car, unfortunately, there has been a rise in cloning number plates. This is where someone has replica number plates made and installed in an often-matching vehicle.
But how do you know if your car's registration has been cloned and what can you do about it if it happens? Let's take a look.
How does car cloning work?
There are various methods by which crooks can clone a car's number plate, but one of the most common is for crooks to search online for similar vehicles to the one they're hiding the identity of.
If they have a white Volkswagen Golf, for example, that they want to clone, they will often search for that car online, and look for images. If images appear of a 'matching car', which is 'clean' they will then have number plates made copying that plate, therefore fully disguising that vehicle's identity.
It is done to hide the identity of a vehicle, often when it's being used to commit a crime or to put on a stolen vehicle so that it adds another level of complexity to it being found.
How do I know if my car registration has been cloned?
The first immediate sign that your car's registration has been cloned is when some kind of fine lands through the post. This is often a Notice of Intended Prosecution (NIP) when it's been caught speeding, or another type of fine, such as running a traffic light or failing to pay the Congestion Charge, or similar.
You should always check the location of the offence, and if that doesn't align with the part of the country you live in, or were in at the time of the offence, alarm bells should immediately be raised. For example, if you live in northern Scotland and get a NIP in from Devon, it's an easy sign that something is not right.
Due to how cars are cloned, there's a good chance that where the vehicle is being caught isn't where you are based.
More alarmingly you might realise by being pulled over by the police. This is often when the vehicle has been used for more high-level crime, such as a robbery or evading the police previously. If you have receipts or other proof on you, this can help to show your car wasn't present at the place of the offence at the time.
What can I do if my car has been cloned?
It can be a concerning time if you realise your car's registration has been cloned, especially if it's a high-level crime.
If you realise that your registration has been cloned, the first thing you should do is contact the police and alert them of this and the offence that has been committed. This could lead to future crimes with your vehicle not being linked by default. The police should also give you a crime reference number.
After this, you should gather as much evidence to show that the car wasn't where the offence was committed at the time. This can include CCTV, either at home or in a work car park, or perhaps photographic evidence you might have taken. If you have any documents with you that have the car's number plate on them and the date/time, these can be especially helpful – parking receipts being a great example.
The next step is to contact the authority or company issuing the fine or NIP to explain it wasn't you that committed the case, and explain that your vehicle's registration has been cloned. The crime reference number can also be given. Following this you should ask for photographic evidence from the offence. You can check this way that it's not the exact fine (it might have different wheels, be a different colour, etc) and if the photo is clear enough, make out that the driver wasn't you.
If problems persist, it might be worth contacting the Driver and Vehicle Licensing Authority (DVLA), which may be able to issue a new registration.
What can I do to prevent my car from being cloned?
These days, cloning cars is easier than ever as crooks don't have to wait to see a matching car in person to be able to take the identity. Instead, many can quickly search online to see similar cars and their number plates.
If posting pictures of your car online, either on social media or when it comes to selling it, for example, it might be a good idea to blur the number plates, making it harder for criminals to see the plates of your particular vehicle.
What can I do to avoid buying a cloned car?
One of the biggest worries should be buying a cloned car. You've seen just how easy it is for crooks to steal the identity of a vehicle, and it can often lead to stolen vehicles being sold. If you're found to be in possession of a stolen car with a cloned plate, even if you had no idea, it's a serious offence and could see the police seize the vehicle and return it to the rightful owner.
To help prevent this from happening, there are some key things to look out for. Buying a vehicle from a reputable dealer is always a good step, as is being cautious of a deal that seems far too good to be true - e.g a car being listed for sale well below its real value. All of Regit's used cars come from main dealers, with a warranty included and 10 day money back guarantee - browse our selection of over 100,000 cars here.
After this, a great step is to check that your car's vehicle identification number (VIN) on the V5C registration certificate matches the number stamped on the car. This can often be found at the bottom of the windscreen. If the numbers don't match, or it looks like the VIN on the car has been tampered with, you should walk away from the deal. |

Print Email Facebook Twitter An Assessment of the Monsoon Water Situation in the Kathmandu Valley Title An Assessment of the Monsoon Water Situation in the Kathmandu Valley: Data collection and analysis of flow, water quality, land use and demand Author Gonzalez Gonzalez, F.D.J. Von Gronau, C.J.E. Izeboud, P. Knook, V.G. Veldhuis, S.A. Contributor Davids, J.C. (mentor) Rutten, M. (mentor) Van Halem, D. (mentor) Faculty Civil Engineering and Geosciences Date 2016-12-15 Abstract Kathmandu, the capital of Nepal, is under increasing water stress. A rising water demand in the Kathmandu Valley is initiated by urbanisation with a rate of 4.7 % per year and amplified by a growing trend of per capita water consumption. At the same time, water availability seems to deteriorate. However, the severity of the problem is hardly known due to immense data gaps. This research aims to (1) estimate the urban water demand from literature research, (2) collect new field data about spring and stream flow, water quality, and ecological stream health, and (3) analyse remotely sensed data in order to characterise the linkages and inter-dependencies between land use, hydrology, and water quality in the Kathmandu Valley. The field data were collected in August and September 2016 and helped to get a decent picture of the water situation. The landuse classification performed using Landsat 8 images had an accuracy of 88 % and proved to be a meaningful source of data to link to the other research topics. Automated SEBAL was attempted to be used for computing evapotranspiration estimates but cannot successfully be used in mountainous areas yet. Penman-Monteith equation was used as alternative. A simplified water balance was performed for the months of August and September 2015. The outcome showed estimates to be 2, 2 x 106 m3/d for ET, 5.6 x 106 m3/d for precipitation, 2.0 x 106 m3/d for the Bagmati outflow and 1.4 x 106 m3/d for groundwater infiltration. To be able to comment on long term groundwater depletion, an annual water budget needs to be performed. The clearest influence on water quality parameters (pH, DO, EC and Rapid Stream Assessment class) was found to be the presence of developed area. With more than 20 % developed area within the considered sub-watershed, the water becomes of such poor quality that it cannot be used for any purpose without extensive treatment. In the headwater areas of the Valley, a significant amount of water with a higher quality (i.e. drinking water) is found in the streams. In September 2016 the total inflow of drinkable water to the Valley floor was estimated to be at least 1.0 x 106 m3/d. This value cannot be considered as fully available for anthropogenic purposes, as water needs to remain in the streams in order to not jeopardise ecosystem services and other functions.

There are different equations to use if are calculating the standard deviation of a sample or of a population. Normal distributions are widely used to model physical measurements subject to small, random errors and are studied in detail in the chapter on Special Distributions. Suppose that \(X\) has the exponential distribution with rate parameter \(r \gt 0\). Compute the true value and the Chebyshev bound for the probability that \(X\) is at least \(k\) standard deviations away from the mean. Here are some more fundamental arguments in favor of the variance. The square root of the variance is the standard deviation (SD or σ), which helps determine the consistency of an investment's returns over a period of time.
The relationship between measures of center and measures of spread will be studied in more detail. Uneven variances between samples result in biased and skewed test results. If you have uneven variances across samples, non-parametric tests are more appropriate. The variance is usually calculated automatically by whichever software you use for your statistical analysis. But you can also calculate it by hand to better understand how the formula works.
Read and try to understand how the variance of a Poisson random variable is
derived in the lecture entitled Poisson
distribution. Then the second observation is not random as it must be the balancing act vs the first observation — in order to equal the sample mean. Because we 'lose the randomness' of 1 observation then we only have n-1 degrees of freedom. It's not an argument that really makes sense in my head as to why we end up using a slightly tighter sampling distribution but it's still interesting. Since we already know that variance is always zero or a positive number, then this means that the standard deviation can never be negative since the square root of zero or a positive number can't be negative.
In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation. The standard deviation is a number that measures how far data values are from their mean. As usual, we why is variance always positive start with a random experiment modeled by a probability space \((\Omega, \mathscr F, \P)\). Suppose that \(X\) is a random variable for the experiment, taking values in \(S \subseteq \R\). Recall the expected value of a real-valued random variable is the mean of the variable, and is a measure of the center of the distribution.
However, there is one special case where variance can be zero. But how do you interpret standard deviation once you figure it out? If the points are further from the mean, there is a higher deviation within the data.
The variance in this case is 0.5 (it is small because the mean is zero, the data values are close to the mean, and the differences are at most 1). Since each difference is a real number https://cryptolisting.org/ (not imaginary), the square of any difference will be nonnegative (that is, either positive or zero). When we add up all of these squared differences, the sum will be nonnegative.
Note the location and size of the mean \( \pm \) standard deviation bar in relation to the probability density function. Run the simulation 1000 times and compare the empirical mean and standard deviation to the distribution mean and standard deviation. In statistics, variance measures variability from the average or mean. It turns out that the sum of squared deviations from the sample mean will always be smaller than those around the true population mean. Because of this, our sample variance (if uncorrected) will always be an under-estimate of the population variance. The use of n-1 instead of n degrees of freedom fixes this because the lower the degrees of freedom of a chi-square distribution the tighter the distribution.
This means you have to figure out the variation between each data point relative to the mean. Therefore, the calculation of variance uses squares because it weighs outliers more heavily than data that appears closer to the mean. This calculation also prevents differences above the mean from canceling out those below, which would result in a variance of zero.
The differences between each return and the average are 5%, 15%, and −20% for each consecutive year. An outlier changes the mean of a data set (either increasing or decreasing it by a large amount). Based on this definition, there are some cases when variance is less than standard deviation. Note that this also means that the standard deviation is zero, since standard deviation is the square root of variance.
Note that mean is simply the average of the endpoints, while the variance depends only on difference between the endpoints and the step size. If your sample has values that are all over the chart then to bring the 68.2% within the first standard deviation your standard deviation needs to be a little wider. If your data tended to all fall around the mean then σ can be tighter. In other words, whether to use absolute or squared error depends on whether you want to model the expected value or the median value.
The relationship between measures of center and measures of spread is studied in more detail in the advanced section on vector spaces of random variables. In many ways, the use of standard deviation to summarize dispersion is jumping to a conclusion. You could say that SD implicitly assumes a symmetric distribution because of its equal treatment of distance below the mean as of distance above the mean.
The sample variance would tend to be lower than the real variance of the population. When you collect data from a sample, the sample variance is used to make estimates or inferences about the population variance. The standard deviation is useful when comparing data values that come from different data sets. If the data sets have different means and standard deviations, then comparing the data values directly can be misleading.
You typically measure the sampling variability of a statistic by its standard error. Assuming that the distribution of IQ scores has mean 100 and standard deviation 15, find Marilyn's standard score. The distributions in this subsection belong to the family of beta distributions, which are widely used to model random proportions and probabilities. The beta distribution is studied in detail in the chapter on Special Distributions. As I see it, the reason the standard deviation exists as such is that in applications the square-root of the variance regularly appears (such as to standardize a random varianble), which necessitated a name for it. The square root of the sum of squares is the $n$-dimensional distance from the mean to the point in the $n$ dimensional space denoted by each data point. |
Strong Adolescent-Parent Relationships Linked to Better Long-Term Health Outcomes, Finds CHOP Study
A new study by researchers from the Children's Hospital of Philadelphia (CHOP) suggests that adolescents with strong relationships with their parents experience better long-term health outcomes, including improved mental and sexual health, and reduced substance abuse in young adulthood. The study findings, published in JAMA Network Open, highlight the potential for investing in improving parent-adolescent relationships to promote general wellbeing.
While prior research has shown that positive parent-adolescent relationships can improve overall health outcomes and reduce the risk of substance abuse, these studies have often been limited by small sample sizes and a lack of diversity. In contrast, this study, which utilised data from the National Longitudinal Study of Adolescent to Adult Health, included over 15,000 adults who were initially enrolled in the study in the mid-1990s when they were between 12 and 17 years old.
The researchers tested whether adolescents' reports of specific, measurable characteristics of their relationships with mother- and father-figures with whom they live were linked to health outcomes measured 14 years later. The study controlled for age, race, ethnicity, family structure, and other factors.
Participants who reported higher levels of warmth, communication, time together, academic expectations, relationship or communication satisfaction, and inductive discipline with both their mothers and fathers reported significantly higher levels of general health in young adulthood. Additionally, they reported higher levels of optimism and romantic relationship quality, and lower levels of stress and depressive symptoms. Higher levels of adolescent-reported parental warmth, time together, and relationship or communication satisfaction were also associated with lower levels of nicotine dependence and substance abuse in young adulthood, as well as lower odds of unintended pregnancy.
"Efforts to strengthen parent-adolescent relationships may have important long-term health benefits," said senior study author Carol A. Ford, MD, Chief of the Craig-Dalsimer Division of Adolescent Medicine and the Orton P. Jackson Endowed Chair in Adolescent Medicine at CHOP. |
– A Global Celebration of Human Rights through Arts & Culture –
In celebration of International Human Rights Day, on Saturday December 12, 2009 United4Iran will facilitate Arts United 4 Iran, a day devoted to worldwide displays of musical, visual, and performing arts highlighting the issues of human rights in Iran. This is a non-partisan event focusing on human and civil rights in solidarity with the people of Iran. Why Arts United 4 Iran? Musicians, performers, artists, writers, and concerned citizens will use Arts United 4 Iran as a medium to express their solidarity with the Iranian people and artists' struggle for human and civil rights. Art is a universal expression that connects humanity across time and space and it has been the voice of justice, peace and rights throughout time. Currently many brave artists in Iran are speaking up to demand basic rights and we need to support them. Why on 12.12? 12.12 is the first Saturday after International Human Rights Day (IHRD), which coincides with the 61st anniversary of the General Assembly's adoption and proclamation of the Universal Declaration of Human Rights. It is also the six-month anniversary of June 12th, the beginning of the peaceful protests in Iran that were violently put down. IHRD is historically marked by supporters engaging in action in support of human rights.
"Without art, the crudeness of reality would make the world unbearable." -George Bernard Shaw "Art is opening up of eyes, minds, hands, and … art matters because it is universal." -Alice Buttrick

In Florida, an Amnesty chapter, with the help of U4I, is working tirelessly on a state-wide concert. For a complete list of locations participating, please see the event map . Dozens of smaller events will also take place at local venues, museums, homes and galleries; details will be released as they become available. Many artists and concerned citizens will express their solidarity online through messages of support and expression through the art to be shown on the United4Iran website on 12.12. What do the events look like? A participant's involvement in Arts United 4 Iran could range from an online message, a song performed in a coffeehouse, living room, community center, or workplace, to a photographic display, a poetry slam, a gallery exhibit, a theatrical performance, or a rock concert. The possibilities of how to participate in Arts United 4 Iran are limitless. The events planned thus far include online messages of support, exhibitions, photo galleries, concerts, theatrical showings, and movie screenings. Read more here. Our vision of success:
- Tens of thousands of people and hundreds of artists around the world join together at hundreds of events on 12.12 in support of the people of Iran and in the celebration of their flourishing civil rights movement.
- Extensive mainstream and online media coverage both in and outside of Iran.
I am a non-Iranian. Why should I get involved? The piece following was written by an American activist.
"You might ask why Iran? There are thousands of places we could focus on. For me, Iran is important right now because there is a strong, mature internal movement with leaders that support equal rights for women and minorities and free speech and peaceful assembly. They have shown that millions of Iranians want change and are willing to work hard to gain it. Iran is now engaged in an historical struggle for civil rights. Those of us outside Iran can help them most by showing that we are listening and by making sure that their cause is known about around the world."
Many non-Iranians have joined the cause. International sensation U2 has dedicated a number of songs and performances to the opposition in Iran, including one they performed with rap-artist Jay-Z (who comes out around minute 3:14). Artist Wyclef Jean also contributed a phenomenal performance. See the videos below.
Below are also digital paintings (WARNING: SOME ARE DISTURBING) and drawings created in support of the people of Iran.

Bhoodan Movement carried forward the idea of Trusteeship
Urgent Need for Bhoodan like Movement
Siby K. Joseph
Gandhi advocated Trusteeship to avoid a bloody revolution in India and Vinoba's path was Bhoodan. There is an urgent need for a new Bhoodan movement or ideal of trusteeship in the face of emerging challenges in India.
April 18 was the Bhoodan Day. It was on this due to a grand gesture of a landlord the idea of Bhoodan Movement or land gift movement born in the mind of Acharya Vinoba Bhave .
Vinoba was in Shivrampalli village on the outskirts of Hyderabad to participate in the thirdannual conference of All India Sarvodaya Mandal on 13, 14 and 15 April. Vinoba got first hand information about the bloody struggle for land by extremist forces which was going on there.
He was asked to undertake a padyatra to stop violence and bloodshed. On April 18 Vinoba headed to Pochampilli village in Nalgonda district of Telangana . Forty Harijan families without having any piece of land narrated their problems before him . He realized without solving their requirement of land a permanent peace cannot be attained.
In the evening prayer meeting, Vinoba asked if anyone was ready to give two acres each to the landless people for their livelihood. A landowner named Ramachandra Reddy came forward and agreed to give 100 acres. Thus the person responsible for the beginning of the movement was Ramachandra Reddy. Ramachandra Reddy's name became a synonym for Bhoodan. In Pochampilli village we can see the statue of both Ramachandra Reddy and Acharya Vinoba
Bhave. Ramachandra Reddy became a true instrument for a right cause and Vinoba Bhave was a moving spirit. It was not out of fear of bloodshed, people donated land. It was the power of love of nonviolence. Vinoba 's appeal directly went into the hearts of the people. In 1952, Bhoodan evolved into the 'Gramadan' movement in which entire villages were donated.
Lanza del Vasto , a European disciple of Gandhi who was accompanying Vinoba in the Bhoodan movement wrote in the chapter " Bhudan Yagna or the Fire Catches" of his book Gandhi to Vinoba : The New Pilgrimage.
And so he went from village to village telling people who flocked to hear him:
"The earth is like the air, the rain and the sun. She belongs to all, because she belongs to no one except God, who has made her. If there is any one of her sons who can claim to possess her rather than others, that man is undoubtedly the one who can cultivate her with his hands. I think I know of men amongst you who keep more land they and their sons can cultivate… They stand as an obstacle between the worker and his work, between the man who starves and the bread he needs. Let my words fly to your hearts like the arrow of Rama. "These words of Vinoba entered the hearts of the people and created a nonviolent revolution in this country which resulted in the collection of 47 lakh acres of land. Prof. Ramjee Singh,
veteran Gandhian scholar in a foreword to the book edited by Siby K. Joseph and others on trusteeship wrote :
"Gandhi's spiritual heir Acharya Vinoba Bhave started the land gift mission on the line of trusteeship. He achieved a great success in his mission. After Bhoodan, he initiated many other smaller movements for gift of income and wealth, labour, learning etc. But the gift of the entire wealth of a village republic to community ownership was the most practical and revolutionary step in this direction which was supported by all sections of people and political parties in an all party meeting at Yelwal in Mysore in the year 1957. In the meantime, some isolated attempts were also made to introduce workers participation in some factories. Though the Gramdan movement could not make a good progress, it is the hope for a village paradise in India. Without
Gramdan, we could not think of Gramswaraj, which is the goal of Sarvodaya or Gandhian Socialism. In a sense, this is also the fulfilment of Gandhian principle of trusteeship in practice."
Seventy three years have passed since the movement. There is no improvement in the sight of the poor and landless. The 2011 Socio Economic and Caste Census shows that 56% of households in rural India do not own any agricultural land. The NSSO survey on Land and Livestock Holdings as a part of its 70th round (January-December 2013) revealed that the top 7.18% of households own more than 46.71% of the land. It was told to the Parliament on February 3, 2023; no record of the number of landless agricultural labourers in India. With the onslaught of crony capitalism in recent years there has been a lot of land acquisition in the name of infrastructure and industrial development.
Gandhi advocated Trusteeship to avoid a bloody revolution in India and Vinoba's path was Bhoodan. There is an urgent need for a new Bhoodan movement or ideal of trusteeship in the face of emerging challenges in India.

Effective strength training is based on a scientifically-backed, sports and physical training concept called periodization, which involves completing exercises in a particular order to elicit specific effects from your body.
American Heart Association RecommendationsGet at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous aerobic activity, or a combination of both, preferably spread throughout the week. Add moderate- to high-intensity muscle-strengthening activity (such as resistance or weights) on at least 2 days per week
HIIT Research: Helps Post Menopausal women with Type 2 Diabetes lose abdominal weight
Conclusion: With no concomitant [associated] caloric restriction, a HIIT program in postmenopausal women with Type 2 diabetes (twice a week for 16 weeks) appeared to be more effective for reducing central obesity than MICT (medium intensity cardio training, or steady state), and could be proposed as an alternative exercise training program for this population
Increasing and improving your movement patterns so you live a healthier, more comfortable life.
Everyone Has ChallengesStarting in grade school, most people spend the majority of their time each day sitting. This lack of movement causes our core muscles to weaken, which can result in bad posture, muscle pain, and poor circulation. As we age and continue to sit for most of our day, our bodies forget how to move which requires us to re-learn the muscle patterns necessary for a comfortable, healthy lifestyle.
Fitness Fundamentals/Re-Learning the BasicsThere are seven fundamental movement patterns that each person should be comfortable performing (and none of them involve being stuck at a desk, sitting in your car, or chilling on the couch). These movements include:
• Push• Pull• Press• Squat• Lift• Lunge• Rotate
Everything we do each day involves one or more of these movements, which is why all of my training programs focus on improving and increasing your ability to efficiently complete them. I tailor each exercise to help you reach your goals in the most effective and safest way possible.
My ApproachI will work with you to understand your goals, needs, and any problems or concerns you feel may be holding you back. I tailor each session to your specific physical needs to ensure you are working towards the goals that are most important to you.
I am committed to providing a safe, positive, and educational environment for every client and I will ensure you know and understand what exercises you can do safely on your own. Some sessions will involve homework, but don't worry – sometimes your homework will be relaxing at home!
Every program will include different training elements: |
1. What is the current status of DACA in El Paso, Texas?
As an expert in Temporary Protected Status (TPS), I would like to clarify that DACA (Deferred Action for Childhood Arrivals) is a different immigration program from TPS. DACA provides temporary relief from deportation and work authorization to certain undocumented individuals who entered the United States as children. The current status of DACA in El Paso, Texas, is dependent on the nationwide policy set by the U.S. government rather than specific to that location. As of my last update, I can confirm that DACA continues to be in effect, albeit facing legal challenges and changes in policy under different administrations. It is important for DACA recipients in El Paso to stay informed about any updates or changes that may impact their status.
2. How many DACA recipients are there in El Paso?
I do not have access to real-time data and specific numbers of DACA recipients in El Paso. However, as of March 2021, there were approximately 43,000 DACA recipients in the state of Texas. It is essential to note that DACA, which stands for Deferred Action for Childhood Arrivals, is different from Temporary Protected Status (TPS). DACA provides temporary relief from deportation and work authorization for certain undocumented individuals who came to the United States as children, while TPS is a temporary immigration status granted to individuals from specifically designated countries facing ongoing armed conflict, environmental disasters, or other extraordinary and temporary conditions. If you require more up-to-date and precise data on the number of DACA recipients in El Paso, I recommend checking with local immigration advocacy organizations or government agencies for the most recent statistics.
3. What are the eligibility requirements for DACA in El Paso?
In El Paso, as with all other locations in the United States, the eligibility requirements for Temporary Protected Status (TPS) remain consistent across the country. To qualify for TPS, an individual must be a national of a designated country, continuously physically present in the U.S. since the TPS designation date for their country, and continuously residing in the U.S. since the date specified by the government. Additionally, applicants must not have been convicted of certain criminal offenses and meet other eligibility criteria set forth by the Department of Homeland Security. It is essential for individuals seeking TPS to consult with immigration experts or legal professionals to ensure they meet all the specific requirements for their particular circumstances.
4. How can DACA recipients in El Paso renew their status?
DACA recipients in El Paso can renew their status by following the established renewal process provided by U.S. Citizenship and Immigration Services (USCIS). To renew their DACA status, recipients must:
1. Submit Form I-821D, Consideration of Deferred Action for Childhood Arrivals, to USCIS.
2. Include the required supporting documents, such as proof of identity, relationship to the U.S., and continuous residence in the country since their last DACA approval.
3. Pay the applicable renewal fee unless eligible for a fee waiver.
4. Undergo a biometric services appointment, which includes fingerprinting and photography.
It is recommended that DACA recipients seek assistance from immigration advocates or legal professionals to ensure a smooth and successful renewal process. Additionally, staying informed about any policy changes or updates related to DACA is crucial for maintaining legal status in the United States.
5. Are there any local organizations in El Paso that provide support services for DACA recipients?
As an expert in Temporary Protected Status (TPS), I can clarify that while the focus of TPS is on individuals from specific countries facing extraordinary but temporary conditions, DACA (Deferred Action for Childhood Arrivals) recipients are individuals who arrived in the United States as children without legal documentation. Nevertheless, both populations may have overlapping needs for support services, such as legal assistance, healthcare access, mental health resources, and educational opportunities.
1. In El Paso, local organizations may offer such support services for DACA recipients. Some organizations that often provide assistance to immigrants regardless of their particular status include the Border Network for Human Rights, Las Americas Immigrant Advocacy Center, and the Diocesan Migrant & Refugee Services. These organizations frequently offer legal support, know-your-rights workshops, mental health resources, and referrals to other services that could benefit DACA recipients in the region.
2. It is important for DACA recipients in El Paso to research and reach out to these local organizations to inquire about the specific services they provide. DACA recipients may also find support through community centers, legal aid clinics, and local universities that offer resources tailored to undocumented individuals and immigrants. By leveraging the support of these local organizations, DACA recipients in El Paso can access valuable assistance to navigate challenges related to their immigration status.
6. What are the benefits of having DACA status in El Paso?
In El Paso, having Temporary Protected Status (TPS) can provide numerous benefits for individuals facing difficult circumstances in their home countries. Firstly, TPS grants recipients protection from deportation and allows them to remain in the United States legally for a designated period of time. This ensures that individuals can continue living and working in El Paso without fear of being forced to return to dangerous conditions in their home countries. Secondly, TPS also provides individuals with the opportunity to obtain work authorization, allowing them to contribute to the local economy and support themselves and their families. Additionally, TPS recipients may be eligible for driver's licenses and in some cases, access to certain social services. Overall, having TPS status in El Paso can offer stability, safety, and opportunities for individuals seeking refuge from crises in their countries of origin.
7. Are DACA recipients in El Paso eligible for in-state tuition rates at Texas universities?
No, DACA recipients in El Paso are not eligible for in-state tuition rates at Texas universities. DACA, or Deferred Action for Childhood Arrivals, does not provide a pathway to citizenship or confer lawful status in the United States. In Texas, to qualify for in-state tuition rates, students typically need to be U.S. citizens or lawful permanent residents, which DACA recipients are not. Therefore, DACA recipients in El Paso are considered international students or out-of-state residents when it comes to tuition rates at Texas universities. It is important for DACA recipients to seek out scholarship opportunities and other financial aid options to help fund their education.
8. Can DACA recipients in El Paso apply for employment authorization?
Yes, DACA (Deferred Action for Childhood Arrivals) recipients in El Paso can apply for employment authorization. DACA is a program that provides temporary relief from deportation and work authorization for certain undocumented individuals who were brought to the U.S. as children. DACA recipients are eligible to apply for an Employment Authorization Document (EAD), commonly known as a work permit, which allows them to work legally in the United States.
1. To apply for an EAD as a DACA recipient in El Paso, individuals must submit Form I-765, Application for Employment Authorization, along with supporting documents and the required fee.
2. It is important for DACA recipients to ensure that their DACA status is current and not expired before applying for an EAD to avoid potential employment authorization issues.
3. DACA recipients should also stay informed about any changes in immigration policies and regulations that may impact their eligibility for employment authorization.
9. What are the potential legal risks for DACA recipients in El Paso?
Potential legal risks for Deferred Action for Childhood Arrivals (DACA) recipients in El Paso include:
1. Changes in immigration policies: DACA is a temporary protection that can be revoked or altered by executive action or new legislation, leading to uncertainty for recipients.
2. Increased enforcement actions: DACA recipients are not immune to immigration enforcement efforts, and they could be targeted for removal proceedings if they are found to be ineligible or if their DACA status is terminated.
3. Travel restrictions: DACA recipients face limitations on international travel, and any violations of these restrictions could endanger their status and lead to potential legal repercussions.
4. Criminal activity: DACA recipients are required to maintain a clean criminal record to remain eligible, so any criminal convictions or involvement in illegal activities can jeopardize their DACA status and make them vulnerable to deportation.
5. Lack of permanent solution: DACA is not a pathway to permanent residency or citizenship, leaving recipients in a state of limbo with uncertain future prospects.
6. Changes in eligibility criteria: The qualifications for DACA may change over time, and recipients could find themselves no longer meeting the requirements, putting their legal status at risk.
Overall, DACA recipients in El Paso face a variety of potential legal risks that could impact their immigration status and lead to serious consequences if not properly addressed. It is crucial for them to stay informed about changes in immigration policies and to seek legal counsel to navigate any legal challenges they may encounter.
10. How has the recent political climate impacted DACA recipients in El Paso?
The recent political climate has had a significant impact on DACA recipients in El Paso. Here are some ways it has affected them:
1. Increased uncertainty: DACA recipients in El Paso are facing increased uncertainty due to the changing policies and rhetoric surrounding immigration at the federal level. This uncertainty can cause stress and anxiety among recipients who are unsure about their future in the country.
2. Heightened fear of deportation: The anti-immigrant sentiment in the current political climate has led to a heightened fear of deportation among DACA recipients in El Paso. The threat of losing their protected status and being forcibly removed from the country is a constant concern for many recipients.
3. Limited access to benefits and resources: The current political climate has also resulted in limited access to certain benefits and resources for DACA recipients in El Paso. This can make it more difficult for recipients to access important services such as healthcare, education, and employment opportunities.
Overall, the recent political climate has created a challenging environment for DACA recipients in El Paso, impacting their sense of security, well-being, and access to essential resources.
11. Are there any specific scholarships or financial aid opportunities for DACA recipients in El Paso?
There are several scholarships and financial aid opportunities available specifically for DACA recipients in El Paso. Some options include:
1. The Hispanic Scholarship Fund, which offers scholarships to DACA recipients of Hispanic heritage.
2. The Dream.Us National Scholarship, which provides support for DACA students pursuing higher education.
3. The Golden Door Scholars Program, which offers scholarships to DACA recipients who demonstrate academic excellence and financial need.
4. The Apple Ibarra Scholarship, which assists DACA students in El Paso pursuing a college degree.
Additionally, it is recommended for DACA recipients in El Paso to look into local community organizations, colleges, and universities that may offer specific scholarship programs or financial aid tailored to their needs.
12. Can DACA recipients in El Paso travel outside of the United States?
Yes, DACA recipients in El Paso and throughout the United States can apply for advance parole to travel outside of the country for educational, employment, or humanitarian reasons. However, it is essential to consult with an immigration attorney before making any travel plans to ensure strict compliance with the regulations and requirements of DACA and advance parole. This process can be complex and requires careful planning to avoid jeopardizing the recipient's immigration status. DACA recipients must receive approval for advance parole before leaving the United States and should be aware of the potential risks involved in traveling abroad, such as being denied reentry into the country.
13. How can DACA recipients in El Paso protect themselves from immigration enforcement actions?
1. DACA recipients in El Paso can protect themselves from immigration enforcement actions by staying informed about their rights and responsibilities under the program. It is important for them to have a clear understanding of what DACA provides, as well as any recent updates or changes that may impact their status.
2. They can also stay connected with reliable legal resources and immigration advocacy organizations in the area. These resources can provide guidance on how to handle encounters with immigration officials, as well as assistance in case of any legal issues that may arise.
3. DACA recipients should carry their employment authorization card (EAD) with them at all times and be prepared to present it if asked by law enforcement or immigration officers. They should also be cautious about sharing personal information or documents with anyone other than authorized personnel.
4. It is advisable for DACA recipients to have an emergency plan in place in case of detention or deportation. This may include informing trusted individuals about their situation, having contact information for a legal representative readily available, and having important documents stored in a secure location.
5. Lastly, DACA recipients should be cautious about engaging in any activities that may put them at risk of immigration enforcement actions, such as participating in protests or public demonstrations. It is important for them to prioritize their safety and well-being while navigating the complexities of the current immigration landscape.
14. What options do DACA recipients in El Paso have if they are facing deportation proceedings?
DACA recipients in El Paso who are facing deportation proceedings have several options available to try to prevent removal from the United States:
1. Seek legal representation: DACA recipients should immediately contact an immigration attorney or accredited representative to assess their case and explore potential defenses against deportation.
2. Apply for relief: Depending on the individual circumstances, DACA recipients may be eligible for other forms of relief from removal, such as asylum, cancellation of removal, or adjustment of status.
3. Request a continuance: DACA recipients can request a continuance in their deportation proceedings to allow time to gather evidence, secure legal representation, or pursue other options.
4. Appeal the decision: If a deportation order has already been issued, DACA recipients can file an appeal with the Board of Immigration Appeals to challenge the decision.
5. Consider voluntary departure: In some cases, DACA recipients may choose to voluntarily depart the United States to avoid a formal deportation order, which could have negative consequences for future immigration options.
Overall, DACA recipients in El Paso should seek immediate legal assistance to explore all available options and determine the best course of action to address their deportation proceedings.
15. Are there any specific healthcare resources available for DACA recipients in El Paso?
Healthcare resources for DACA recipients in El Paso are limited due to their immigration status. However, there are certain options available to them:

2. Community Health Clinics: Some community health clinics in El Paso may provide healthcare services to DACA recipients at a reduced cost or on a sliding fee scale.
3. Nonprofit Organizations: There are nonprofit organizations in El Paso that offer healthcare services specifically for immigrant populations, including DACA recipients. These organizations may provide medical care, mental health services, and other types of support.
It is important for DACA recipients in El Paso to research and inquire about available healthcare resources to ensure they receive the necessary care they need.
16. How can DACA recipients in El Paso access mental health support services?
DACA recipients in El Paso can access mental health support services through a variety of avenues, including:
1. Utilizing community mental health centers: El Paso is home to several community mental health centers that offer affordable or sliding-scale fee services for individuals in need of mental health support.

17. Are DACA recipients in El Paso eligible for state or federal financial assistance programs?
No, DACA recipients in El Paso are not eligible for most state or federal financial assistance programs. DACA (Deferred Action for Childhood Arrivals) is a program that provides temporary protection from deportation and work authorization for certain undocumented immigrants who came to the U.S. as children. However, DACA recipients are not eligible for federal financial aid programs such as Pell Grants or federal student loans. They are also generally ineligible for most state-funded financial assistance programs such as Medicaid, CHIP (Children's Health Insurance Program), and SNAP (Supplemental Nutrition Assistance Program). While some states have taken steps to provide limited benefits to DACA recipients, they are still largely excluded from most government assistance programs.

Remember, it's not just about the words you say but also the messages you convey through your actions and attentiveness.
She needs space
If your girlfriend requires space, her silence can be a way of establishing boundaries, promoting self-reflection, and encouraging personal growth within the relationship.
Space in a relationship allows both partners to breathe, explore their individuality, and nurture their own interests outside of the partnership. It gives room for personal development and self-awareness, which are crucial for maintaining a healthy connection. Healthy boundaries create a sense of respect and understanding between the two people involved, enabling them to appreciate each other's needs and feelings without feeling suffocated or neglected. By giving each other the space to grow, a relationship can flourish with mutual trust and communication.
Actions to Take When Your Girlfriend Won't Talk to You
Navigating a situation where your girlfriend won't talk requires a delicate balance of understanding her emotions, providing support, and engaging in effective communication strategies.
When your partner chooses to remain silent, it's crucial to acknowledge that everyone communicates differently.
Start by creating a safe space for her to open up on her terms. Show your girlfriend that you're there for her without pressure or judgment, allowing her room to express herself when she's ready.
Remember, listening attentively and being patient can go a long way in building trust.
Consider using non-verbal cues such as gentle touches or thoughtful gestures to convey your support and understanding.
Try talking to her calmly
Initiate a calm and honest conversation with your girlfriend to address the root of the communication barrier, listen attentively to her perspective, and validate her emotions.
By creating a safe space for open dialogue, you're offering her the opportunity to express her feelings without judgment. Remember, effective communication is a two-way street; encourage her to share her thoughts and actively listen to what she has to say. In conflicts, acknowledging her emotions demonstrates empathy and shows that you value her feelings. Expressing understanding and empathy can help dissolve tensions and deepen your connection.
Give her time and space
Respect your girlfriend's need for space by giving her time to process emotions, set healthy boundaries, and engage in self-reflection without pressure or intrusion.
Understanding the importance of granting space in relationships is essential for fostering emotional well-being and strengthening the bond between partners. By allowing your significant other the time and freedom to navigate their feelings and thoughts independently, you not only demonstrate trust and respect but also facilitate their personal growth.
This act of respecting boundaries promotes a sense of autonomy and self-awareness, enabling both individuals to maintain a healthy balance between togetherness and individuality. It is crucial to recognize that setting boundaries is a form of self-care that contributes to the overall harmony of the relationship.
Reflect on recent events
Take time to reflect on recent events in your relationship, analyze emotional dynamics, enhance understanding, and identify areas for personal and relational growth.
By engaging in this introspective process, you open doors to deeper self-awareness and empathy towards your partner. Recognizing your emotional triggers and reactions can help you communicate more effectively and navigate conflicts with greater understanding and patience. Remember that emotional intelligence plays a crucial role in sustaining healthy relationships, as it allows you to regulate your emotions and respond thoughtfully rather than react impulsively.
Consider her emotional state
Prioritize understanding your girlfriend's emotional state by offering support, empathetic listening, and a safe space for her to express her feelings without judgment.
Emotional awareness is key in any relationship, creating a bond based on trust and understanding. Remember, sometimes she might need you just to listen rather than give solutions. Encourage open communication and validate her emotions to nurture a strong connection. Make sure to demonstrate your support through actions that show you are there for her whenever she needs to talk. By prioritizing her emotional well-being, you are fostering a healthier, more intimate relationship.
Focus on self-improvement
Channel your energy into personal growth and self-improvement to enhance confidence, attract positive attention, and strengthen your relationship dynamics with your girlfriend.
Self-development is a crucial aspect of nurturing any relationship.

Guinea pig family units are centered on an alpha male, which would usually be the father in natural circumstances. However, there are times when mature male guinea pigs will fight and possibly cause physical harm or distress to their offspring. So, when keeping guinea pigs as pets, should you allow the father to be with the babies?
It is common practice to allow the father guinea pig to be with his babies for short periods for socialization, learning, and emotional bonding. However, the father's behavior toward the babies should be closely monitored for signs of dominance and aggression.
A further concern is that the father might impregnate the mother guinea pig soon after she has given birth. This is not ideal for the mother, as she needs time to recover and nurse the babies. Read on to understand the pros and cons of keeping a father guinea pig with his babies.
Advantages of Keeping A Father Guinea Pig With His Babies
In most cases, it can be beneficial to keep the father guinea pig with the mother and babies after the babies are born. This is because male guinea pigs (boars) generally display good paternal instincts and can play a positive role in the social development of their offspring. Below are some reasons why it could be advantageous to keep the father guinea pig with the mother and piglets:
Guinea pigs thrive on companionship because they are social animals. Therefore, if the father guinea pig is kept with the family group, it will provide additional social interaction for all concerned. This can contribute to the family group's overall well-being.
Teaching and Social Learning
Baby guinea pigs learn by observing and imitating their parents. By keeping the father guinea pig with his babies, he can act as a role model for them and help teach them social skills and important behaviors. In this way, a father can contribute to his babies' development.
The father guinea pig can help protect his babies against dangers and potential threats in their environment. For example, he may display protective behaviors such as keeping watch, giving warning vocalizations, and even physically defending the young ones.
Emotional Bonds
Guinea pigs form emotional bonds with each other. Keeping the father with the family can help maintain the emotional bond between him and the mother guinea pig. Conversely, separating them could cause anxiety and stress for both parents, potentially affecting their overall well-being.
If you're considering housing the father guinea pig with the babies, you'll need to consider cage size and layout. Learn more about the ideal cage here.
Why And When To Separate A Father Guinea Pig From His Babies
There are good reasons to separate a father guinea pig from his babies, but this usually only needs to happen once the babies are weaned. However, some people firmly believe that the father must be separated from the mother before parturition and kept away from the piglets altogether.
Here are some reasons why it might be necessary to separate a father guinea pig from his babies:
To Give The Babies Time With Their Mother
It is recommended to keep the father separated from the mother and babies for the first few days after their birth. This will allow the mother a chance to recover from giving birth, and it will enable the piglets the opportunity to nurse uninhibited. During this time, the babies form a bond with their mother as their prime attachment object.
To Avoid Inbreeding With Female Offspring
Female guinea pigs (called sows) become sexually mature at about six weeks. However, it is best to allow them to mature to twelve weeks before breeding. Father guinea pigs should be separated from their female offspring once they become sexually mature to avoid inbreeding. Inbreeding leads to many health complications.
If The Father Or Male Offspring Show Aggression
Some male guinea pigs can display signs of aggression if they are territorial. Additionally, as young boars start reaching maturity, they may show signs of aggression toward the other males. The father guinea pig might not take kindly to his offspring misbehaving, resulting in a fight.
If the father has an aggressive temperament, he could injure his babies or cause them stress. Even if they don't physically fight, the "pecking order" or tension could cause the baby guinea pigs to be distressed.
When the father guinea pig is with the babies, jealousy might arise among the group. Learn more about guinea pig emotions here.
Monitor Interactions Carefully
It is recommended to closely monitor the interactions between your guinea pigs after the babies have been born. If you decide to keep the father with the family, check out the individuals regularly to determine if there are signs of physical harm or stress to the babies.
If you separate the father but notice he is pining for the mother, try to reintroduce him to the enclosure, but monitor his behavior around the babies.
Ensure there are sufficient hiding places for the guinea pigs to escape their companions. Baby guinea pigs are more precocial than other rodents when they are born, allowing them the opportunity to run away from harm. However, they will need smaller hiding places to prevent the father from reaching them if he is aggressive.
Understanding guinea pig sounds can help you monitor the interactions between the father and the babies. Learn more here.
Other Considerations
Like most rodents, guinea pigs can breed multiple times in a year. Therefore, keeping the father guinea pig with the mother after she's given birth could result in him impregnating her soon after. However, if other males are nearby, they will try to mate with her just after she's given birth unless the father is there to fend them off.
So, suppose you aren't planning on breeding guinea pigs and want to be a conscientious pet owner. In that case, it is better to have the father neutered as soon as possible.
Likewise, male and female siblings and parents should be separated after weaning to avoid unwanted pregnancies and inbreeding.
You can allow a father guinea pig to be with his babies as long as it is under close supervision. The advantages of allowing him to be with his babies include socializing, protection, learning, and forming emotional bonds. However, if he displays aggressive behavior, he should be kept away from his babies for their safety.
Howdy! I'm Luna. By day, I navigate the world of human medicine as a practicing physician. But off the clock, my world is enlivened by some truly unique personalities — not colleagues, but guinea pigs!

Hepatitis C virus (HCV) primarily affects the liver, but it can also manifest in extrahepatic manifestations, including arthritis. The prevalence of arthritis in HCV-infected individuals varies, with estimates ranging from 10% to 60%. Several mechanisms contribute to the development of HCV-associated arthritis.
One mechanism involves the deposition of immune complexes in the joints, triggering an inflammatory response. HCV infection leads to chronic stimulation of the immune system, resulting in the production of autoantibodies. These autoantibodies can form immune complexes that accumulate in the joints, leading to inflammation and arthritis.
Another proposed mechanism is molecular mimicry, where viral proteins resemble host proteins. Antibodies produced against HCV may cross-react with self-antigens, triggering an immune response against joint tissues. This molecular mimicry can result in chronic arthritis in some HCV-infected individuals.
Chikungunya Virus (CHIKV)
Chikungunya virus (CHIKV) is a mosquito-borne virus that has gained attention due to its association with arthritis. Following CHIKV infection, joint symptoms typically manifest within a few days to weeks and are characterized by severe joint pain, swelling, and stiffness. The arthritis caused by CHIKV infection can be acute, subacute, or chronic.
CHIKV-induced arthritis is thought to be driven by both viral persistence and an immune-mediated response. The virus can establish chronic infection in the joint tissues, leading to ongoing inflammation. Additionally, the host immune response plays a crucial role in the pathogenesis of CHIKV-induced arthritis. The immune system recognizes viral antigens and triggers an inflammatory response, resulting in joint inflammation.
The exact mechanisms by which CHIKV induces arthritis are not fully understood, but it has been observed that the virus can directly infect synovial cells and trigger the release of pro-inflammatory cytokines. These cytokines promote inflammation and joint destruction, contributing to the development of arthritis.
Epstein-Barr Virus (EBV)
Epstein-Barr virus (EBV), a member of the herpesvirus family, is a common viral infection that is known to cause infectious mononucleosis (also known as glandular fever) in adolescents and young adults. In addition to its association with mononucleosis, EBV has been linked to the development of arthritis in some individuals.
EBV-induced arthritis typically presents as a symmetrical polyarthritis, affecting multiple joints simultaneously. The joint symptoms can range from mild to severe and may include pain, swelling, stiffness, and limited range of motion. The arthritis associated with EBV infection can persist for weeks to months, and in some cases, it can become chronic.
The exact mechanisms by which EBV triggers arthritis are not fully understood. It is believed that the immune response to EBV plays a significant role in the development of arthritis. The virus can persist in B cells, and the immune system's response to these infected cells can result in chronic inflammation in the joints. Additionally, immune complexes formed during the course of the infection may deposit in the joints, further contributing to joint inflammation.
Adenoviruses are a group of DNA viruses that can cause a wide range of respiratory and gastrointestinal infections. While adenovirus infections are typically associated with symptoms such as fever, sore throat, and cough, they have also been linked to the development of arthritis in some cases.
Adenovirus-induced arthritis primarily affects children, especially those with a weakened immune system. The exact prevalence of adenovirus-associated arthritis is not well-defined, but it is considered a relatively rare complication of the infection. It is believed that the immune response to the viral infection plays a significant role. The virus can cause an immune-mediated reaction that leads to joint inflammation and subsequent arthritis. Additionally, viral particles may directly infect joint tissues, causing local inflammation and damage.
The joint symptoms associated with adenovirus-induced arthritis typically include joint pain, swelling, and limited mobility. The arthritis may be acute, self-limiting, and resolve on its own within a few weeks, or it may persist and become chronic in some cases.
Zika Virus
Zika virus, transmitted primarily by Aedes mosquitoes, gained global attention due to its association with microcephaly in infants. In addition to neurological complications, Zika virus infection can also cause arthritis.
Joint symptoms, including pain, swelling, and limited mobility, can develop during or after the acute phase of the infection. The immune response and potential direct viral effects on joint tissues contribute to the development of Zika virus-induced arthritis.
Mumps Virus
The mumps virus is a highly contagious RNA virus that primarily affects the salivary glands but can also lead to arthritis as a complication. Mumps-induced arthritis typically presents as joint pain, swelling, and stiffness, predominantly affecting large joints. The immune response to the viral infection and potential direct viral involvement in joint tissues contribute to the development of arthritis.
Other Viruses Associated with Arthritis
In addition to HCV and CHIKV, several other viruses have been linked to the development of arthritis. These include:
1. Parvovirus B19: Parvovirus B19 infection can cause acute arthropathy, particularly in adults. It is characterized by symmetrical joint pain and swelling, often affecting the hands, wrists, and knees.
2. Rubella virus: Rubella infection, primarily known for its association with congenital defects, can also cause arthritis. It typically presents as a transient polyarthritis, affecting multiple joints.
3. Human Immunodeficiency Virus (HIV): HIV infection can lead to various rheumatic manifestations, including arthritis. HIV-associated arthritis is often symmetric and involves large joints.
Several other viruses have been linked to the development of arthritis. These include alphaviruses such as Ross River virus and Barmah Forest virus. Each virus has unique characteristics and mechanisms of arthritic involvement, often involving immune-mediated responses and inflammation in joint tissues.
Viral-induced arthritis encompasses a diverse range of viruses, each with its specific mechanisms and clinical presentations. Hepatitis C virus and Chikungunya virus are two notable examples of viruses that can cause arthritis. HCV-induced arthritis involves immune complex deposition and molecular mimicry, while CHIKV-induced arthritis is driven by viral persistence and an immune-mediated response.
Understanding the mechanisms behind viral-induced arthritis is crucial for accurate diagnosis and effective management. Although the specific mechanisms vary for each virus, immune-mediated responses, inflammation, and potential direct viral effects on joint tissues play significant roles.

Becky Hitchin presents a tale of two crabs, both unwelcome guests on either side of the planet.
This month, I want to tell tales of two invasive species, both crustaceans. One of these is native in UK waters and has become invasive worldwide, and one has invaded the UK.
Invasive species #1: shore crab
So firstly, the shore crab, aka the green crab, Carcinus maenas, beloved of small children due to its attraction to pieces of bacon hung on the end of long strings over jetties. This seemingly inoffensive little crab has also been listed as one of the '100 worst invasive species'. It is native to European coasts, but has sequentially invaded the world. It was first seen on the east coast of North America in 1817, and now occurs from South Carolina to Newfoundland. In the 1850s, it was also introduced into Australia. These periods of dispersal occurred through transport by ships (in hull fouling or in solid ballast).
The shore crab reached New South Wales in 1971, South Australia in 1976 and Tasmania in 1993. It reached South Africa in 1983 and South America by 2003. In 1989, it was also found in California and in Canada in 1999. Making its way up the Pacific coast of America, the shore crab extended its range by 750km in 10 years. These introductions are more likely to have occurred through a greater variety of dispersal mechanisms, including the more traditional hull fouling and ballast water releases but also more technological mechanisms such as fouling on semisubmersible drilling platforms, transport with fisheries products intended for food or bait, scientific research or releases from aquaria.
Shore crab
This inoffensive little crab has caused major economic impacts on shellfisheries in New England, and may have similar effects on fisheries on the West Coast of North America and Australia. Ecologically, it has impacted many shore communities by preying on, and competing with, other crabs, bivalves and gastropods. Not so inoffensive really!
Invasive species #2: Chinese Mitten Crab
The second crab is an invader of our waters – the Chinese Mitten Crab, Erocheir sinensis, also known as the Shanghai Hairy Crab and the Big Sluice Crab. It's a burrowing crab native to rivers, estuaries and other coastal habitats of East Asia named for its furry, brown, mitten-like claws. It is also listed as one of the world's 100 worst invasive species due to the damage it can wreak on the environment by burrowing into riverbeds and embankments, blocking drainage systems and damaging fishing gear with its sharp claws. They eat fish eggs and outcompete native species for resources. Over the past century, the crabs have spread around the world, including Europe and North America, migrating through ballast water in commercial ships.
The species was first spotted in the UK in 1935 in the Thames and has since become established around the country.
There are a few dive lakes in Kent where you can see the crabs marching between the waterbodies at dusk. In 1995 residents of Greenwich saw them crawling out of the River Thames, and in 2014 one was found in the Clyde, in Scotland. The crabs have even been known to take up residence in swimming pools.
How divers and snorkellers can help
What to do about these invaders? There have been fisheries set up to try and decrease their numbers. In Massachusetts, more than 10 tonnes of shore crabs were caught in one year in an experimental fishery. In China, there have been ideas of reimporting crabs from the West to replenish Chinese fisheries, where the mitten crab is seen as a delicacy.
There's no moral to this story. No easy way to reverse invasions. Our underwater world is changing, forever, and it's up to us as divers, snorkellers and shore surveyors to at least document, photograph these changes and help understand our changing seas.

Article Text
Introduction Caregiver burden is a significant issue in the care of patients with advanced kidney disease. Its assessment is crucial for evaluating the needs of caregivers and for the development of interventions to support them. Several instruments have been developed to measure caregiver burden in these patients. However, the measurement properties of these instruments have not been systematically reviewed.
Methods and analysis This systematic review will include a comprehensive search of databases including PubMed, CINAHL, Embase, Cochrane Library, SCOPUS and Web of Science by using keywords and MeSH terms to identify relevant studies starting from each database inception to 1 January 2024 and covering papers in English. The search strategy will combine relevant keywords and database-specific subject headings related to the following concepts: (1) caregivers, (2) burden, stress, distress, (3) chronic kidney disease, end-stage kidney disease, dialysis. Reference lists of eligible articles will also be hand searched. We will include quantitative and qualitative studies evaluating measurement properties of instruments assessing caregiver burden in caregivers of adult patients (aged ≥18 years). Data will be extracted from the selected studies and analysed using the COnsensus-based Standards for the selection of health Measurement INstruments checklist as the study quality assessment tool. Subsequently, the van der Vleuten utility index will be used to critique and categorise the instruments. A narrative that synthesises the utility of all instruments will be presented along with recommendations for the selection of instruments depending on specific clinical contexts. This systematic review will provide an overview of the measurement properties of available instruments, including discussion on reliability, validity and responsiveness. Results from the review may give rise to the subsequent development of most appropriate instrument that could be applied to the assessment of caregiver burden in advanced kidney disease.
Ethics and dissemination Ethics approval is not required as this study will merely synthesise data from published studies. The results will be disseminated through peer-reviewed publications as well as conference presentations.

Statistics from Altmetric.com
The review implements a comprehensive search strategy across databases, reference lists and author contacts to comprehensively capture all studies validating caregiver burden instruments in late-stage chronic kidney disease patients.
The review will adopt Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for reporting to ensure transparency, completeness, and applicability; and COnsensus-based Standards for the selection of health Measurement INstruments guidelines for in-depth analysis of the methodological quality of included studies on measurement properties.
A dual reviewer process for screening, extraction and adjudicating disagreements is used to systematically minimise risk of bias and errors at all review stages.
The restriction to English-language studies risks precluding some potentially relevant non-English caregiver burden research from being considered.
Variability in study designs and conceptualisations of caregiver burden may impact interpretability and synthesis of results.
Chronic kidney disease (CKD) is one of the most common chronic diseases in the world with a global prevalence of 11.0%–13.4%.1 Patients with advanced kidney disease comprise of individuals with CKD who are in stage 4 or 5.2 Caregivers of patients with CKD are often required to take on multiple responsibilities and tasks while caring for patients, including the administration of medications, accompanying patients for medical appointments as well as for providing psychosocial and emotional support.3 The burden that arises from these caregiving responsibilities could lead to a reduced quality of life and a compromised state of mental health.4 Caregiver burden can be defined as the strain or load borne by a person who cares for a chronically ill, disabled or elderly family member.3–7 Caregiver burden typically manifests as high rates of psychological distress, mental health diagnoses, fatigue, sleep disturbances and suicide attempts, which, if left unattended, may lead to a rippling effect on patients' health and, eventually, the healthcare system.5 8–14 Caregiver burden in the context of this research is defined as the multifaceted strain experienced by caregivers encompassing psychological, physical, financial, emotional and social stressors. This comprehensive definition guides our inclusion and exclusion criteria for selecting studies in this systematic review.
The urgency of addressing the issue of caregiver burden has been highlighted by studies conducted in both high-income countries like the USA and lower to middle-income countries like Turkey, Vietnam, Jordon, India, China Nigeria.8 15–22 Factors that contribute to caregiver burden may be categorised into patient-related and caregiver-related factors. Patient-related factors include the extent to which patients are dependent on their caregivers for physical and emotional well-being, which in turn depends on the patient's functional limitations, cognitive impairment and disease severity.23 Caregiver-related factors include the demographics of caregivers, the nature of their caregiving role, relationship with the patients, health status of caregivers and financial strain that results from caregiving.24
Measuring caregiver burden in patients with advanced kidney disease is important for understanding the impact of caregiving, identifying areas where caregivers are experiencing difficulty, supporting targeted interventions for mitigating the impact of caregiver burden, tracking changes in caregiver burden over time as disease severity changes, understanding the differences in burden for various types of caregivers (formal, informal and caregivers with cultural differences) and in evaluating targeted healthcare policies and programmes for caregivers.25 26
However, the measurement properties of available assessment tools have not been systematically evaluated for advanced kidney disease. The absence of appraisal of measurement properties restricts the evidence-based selection of caregiver burden assessment tools optimised for specific research contexts, cultural groups, informal or formal caregiver populations and healthcare settings in advanced kidney disease. Therefore, a systematic review of the measurement properties of tools to assess caregiver burden in advanced kidney disease could guide clinicians on the appropriate use of different tools depending on specific clinical contexts.
This study specifically addresses advanced kidney disease because this disease is distinct in its severity and complexity, imposing a uniquely multifaceted and intense burden on caregivers when compared with other chronic conditions.27 With its relentless progression, high mortality and extensive treatment demands including long-term dialysis, providing care to patients with advanced kidney disease demands a different set of skills, a certain degree of resilience and resourcefulness. Current generic tools for assessing caregiver burden in chronic diseases may fall short in accurately capturing the full range of emotional, physical and psychological stresses unique to this context. Our systematic review aims to identify and evaluate these existing tools, highlighting the need for precise, disease-specific instruments. This is crucial for understanding the unique caregiver burden in advanced kidney disease and developing effective support strategies and interventions.
Instruments used for measuring caregiver burden in earlier studies
There are several instruments for measuring caregiver burden in advanced kidney disease, including the Zarit Burden Interview (ZBI), Short Form 36, Centre for Epidemiological Studies Depression Scale, Beck Depression Inventory, Depression Anxiety and Stress Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, Caregiver Burden Scale, Brief Symptom Inventory, Psychological Adjustment to Illness Scale, Jalowiec Coping Scale, Caregiver Burden Inventory, Caregiver Strain Index and so on.3–6 8 These instruments account for the differences in various aspects of caregiving, population and cultural appropriateness of instruments, and an evolving understanding of the caregiving experience. A systematic review covering 61 studies, identified 70 different scales for assessment of caregiver burden and found significant heterogeneity in study design and outcome measures, which made comparisons between studies difficult.4
These instruments have been mainly validated in specific samples or cultures. However, it is important to ensure that these instruments are appropriate for the population in question and to consider the cultural nuances when interpreting the results. It would be clinically relevant to examine the measurement properties of these instruments in more diverse populations and to conduct longitudinal studies, to better understand the temporal dynamics of caregiver burden in the context of patients with advanced kidney disease. Furthermore, it would be useful to evaluate the responsiveness of these instruments, which refers to the ability of an instrument to detect changes in the outcome of interest over time.3 5
The objectives of our review are:
To identify all available instruments that have been developed to measure caregiver burden in patients with advanced kidney disease. To provide a systematic overview of the existing research on all available instruments.
To review the descriptive aspects of each instrument (eg, respondent requirements, administration type, response format and so on).
To evaluate the measurement properties of these instruments, including internal consistency, reliability, measurement error, content validity (including face validity), structural validity, hypothesis-testing, cross-cultural validity, responsiveness, interpretability, reproducibility agreement, floor and ceiling effects.
To identify the most appropriate instruments for measuring caregiver burden in patients with advanced kidney disease.
Methods and analysis
A well-defined research question is developed using the SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type) framework.28 The research question is focused on assessing the descriptive aspects and components pertaining to the measurement properties of tools deployed to evaluate caregiver burden in advanced kidney disease, which include internal consistency, reliability, measurement error, content validity (including face validity), structural validity, hypothesis-testing, cross-cultural validity, responsiveness, interpretability, reproducibility agreement and floor and ceiling effects.
A search for all relevant studies will be conducted on a set of relevant databases using appropriate search terms (online supplemental file appendix 1). A two-step systematic search will be conducted between September 2023 and June 2024. The first round of search is targeted to provide an inventory of all eligible caregiver burden assessment tools. The second round of search aims to locate the evaluation studies corresponding to all the instruments filtered in the first search (figure 1, figure 2). The search will be conducted in multiple databases to ensure a comprehensive search for all relevant studies. The search will be limited to studies that have been published in peer-reviewed journals and that have been written in English.
Supplemental material
Search strategy
Eligible articles will be screened through PubMed, CINAHL, Embase, MEDLINE, PsycINFO, Cochrane Library, SCOPUS and Web of Science databases, with search strategies devised in accordance to each database. The search will cover studies published in English from each database inception to 1 January 2024. A search strategy for all the databases is provided in online supplemental appendix I. The SPIDER framework will be adopted to perform a comprehensive search for relevant studies.28 The SPIDER framework is a systematic strategy for searching for qualitative and mixed-methods research studies, defining key elements of non-quantitative research questions.29
The sample to be examined is representative of the caregivers of patients with advanced kidney disease. This includes consideration of demographic factors such as age, gender, race and socioeconomic status. The sample size will be reviewed to ensure that the study is adequately powered for the analysis.
Phenomenon of interest
Assessment of caregiver burden is the phenomenon of interest to be studied. The instrument that measures caregiver burden should be appropriate for the population in question and one that measures the physical, psychological, emotional, social and financial aspects of caregiver burden. The instruments will include the ones that measure specific aspects of caregiver burden as well as those assessing multiple dimensions.
Types of study design (eg, quantitative method or mixed methods, experimental, quasi-experimental, pre-experimental and non-experimental studies including cross-sectional, cohort, non-randomised or randomised controlled trials (RCTs), case studies, narrative and scoping reviews), the methodology of data collection (eg, self-report, observation) and the statistical methods used to analyse the data. All studies will be assessed for appropriateness of study design, with reference to the phenomenon of interest.
Evaluation of the measurement properties of the instrument will include considerations such as reliability (eg, test–retest, internal consistency), validity (eg, construct, cross-cultural differences) and responsiveness. All instruments will be assessed for adequacy of its individual measurement properties, with reference to the study population.
Research type
Studies encompassing both the quantitative, qualitative and mixed-methods approaches will be considered.
All studies determined to be eligible in accordance with the inclusion selection questions (online supplemental appendix II) will be selected and included in the review. If required, studies' original development papers may be referenced from, with the authors of these papers further consulted for extraction of missing but pertinent information. The studies will be evaluated independently by two reviewers involved. The two reviewers will independently screen the articles in accordance to the inclusion criteria, extract relevant data and assess the studies for risk of bias. Any discrepancies will be resolved through consensus or with a third reviewer.

Finally, data will be extracted from the included studies (online supplemental appendix III), and the quality of the studies will be assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.30 The extracted data will include information such as the sample size, the instrument used to measure caregiver burden, the methodology used to evaluate the measurement properties, and the results of the study. By analysing the results of eligible studies, extracted data can be synthesised. From here, conclusions on the measurement properties of instruments used to assess caregiver burden in patients with advanced kidney disease can be made. A narrative synthesis will be conducted to summarise the findings of the included studies. The results will be reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
Assessment of measurement properties
Several parameters are used to assess the measurement properties of instruments designed to measure caregiver burden among patients with advanced kidney disease (table 1). These parameters, although interrelated, are mutually exclusive.
Since a gold standard for the assessment of caregiver burden in advanced kidney disease does not exist currently, the measurement property 'criterion validity' will not be considered for the purpose of this systematic review.
Risk of bias and assessment of study quality
In order to ensure that the studies included in the review are reliable, the COSMIN checklist will be used to evaluate the quality of the studies. COSMIN allows for a comprehensive assessment of the methodological quality of systematic reviews. This is achieved through evaluating the quality of each study based on domains such as the representativeness of eligible studies, measurement properties of reference instruments and the impact of missing data. In addition, the COSMIN checklist is used to assess the quality of studies that report on the measurement properties of an instrument, such as its reliability, validity and responsiveness.
The four main domains in evaluating the quality of studies are study design and conduct, measurement properties, sample characteristics and conclusions and reporting (figure 3). The COSMIN checklist is completed for each study by answering questions in each of these domains. Based on the answers provided for each domain, the quality of the studies is rated as either 'good', 'fair' or 'poor'. Table 2 presents the COSMIN definitions of quality levels using the modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, along with their corresponding definitions.
A detailed grading system for 'good', 'fair' and 'poor' quality classifications is provided below:
Good quality: strong and appropriate study design (eg, RCT, cohort study); adequate sample size; low overall risk of bias; directness of evidence for the target population; detailed reporting of measurement properties and results; appropriate statistical analysis methods; no issues identified that would lower confidence in the results.
Fair quality: moderate sample size; some concerns about applicability of study design or execution; some uncertainties or inconsistencies in results; lack of detail on certain measurement properties; outdated methods or suboptimal statistics; some concerns that may lower confidence in the results.
Poor quality: inadequate sample; high risk of bias due to study design or conduct limitations; indirectness of evidence for the target population; incomplete or selective reporting of measurement properties; inappropriate statistical methods; issues that severely lower confidence and reliability of results
These quality levels are used to assess the methodological quality and risk of bias in studies, which evaluate the measurement properties of instruments and tools. The quality level assigned to a study helps determine the strength of evidence provided by that study, subsequently influencing the overall assessment of the measurement properties.
The van der Vleuten utility index
The van der Vleuten utility index is a method for assessing the utility of a measurement instrument.31 The utility of a measurement instrument is dependent on its ability to accurately measure the specified intended outcome, and the practicality of its use in a specific setting. The utility index is calculated by multiplying the validity coefficient of an instrument by a practicality coefficient.
There are various empirical research and statistical analysis methods to estimate validity coefficients, including correlational analyses, factor analyses and expert judgement. The specific calculation depends on the nature of the instrument and the validation study design. The practicality coefficient takes into consideration factors such as time, cost, administration procedures, scoring and resources required to implement the instrument and is typically determined based on expert judgement, experience and considerations of the specific context in which the instrument will be used.
In the context of measuring caregiver burden in patients with advance kidney disease, the utility index can be used to evaluate the measurement properties of instruments used to measure caregiver burden. By calculating the utility index for different instruments, researchers can compare the overall utility of different instruments and select the instrument best suited for their specific study population.
Data synthesis
The data from the included studies will be synthesised by summarising the findings for each instrument and grouping the studies by their quality assessment. The results of the systematic review will be interpreted in the context of the quality of the studies, the consistency and heterogeneity of the results. No meta-analysis is planned due to the expected heterogeneity in the methodologies, instruments and populations studied across different research works. Rather, a narrative synthesis based on the data analysis will be provided.32
Descriptive statistics will be used to present the general characteristics of the studies included in the systematic review to contextualise the findings and identify any patterns or trends across the studies. The quality of methods and measurement property results will be tabulated. The quality of methods table will assess the rigour and validity of the studies, considering factors such as study design, sample representativeness and data collection procedures. This table will enable a comprehensive evaluation of the methodological quality of each study, ensuring the reliability of the findings. Furthermore, a table based on all of the quality criteria of the COSMIN will be used to present the psychometric properties of each systematic review and meta-analysis tool.
Patient and public involvement
Ethics and dissemination
This systematic review will synthesise data from published studies; therefore, ethics approval is not required. The findings will be disseminated through various channels, including publication in a peer-reviewed journal and presentation at relevant webinars and conferences. The review findings will be published in open-access journal to ensure accessibility. The importance of assessing and addressing caregiver burden will be highlighted through knowledge dissemination among healthcare providers, researchers, caregivers and kidney disease patient organisations. It may encourage uptake of suitable instruments in clinical research and practice.
This review will provide valuable insights into the measurement properties of the various instruments used to assess caregiver burden in advanced kidney disease. This may inform selection of appropriate instruments in future studies and ensure accurate assessment of caregiver burden. The results will also reveal any gaps in existing instruments and areas requiring further research, which may also inform development of new instruments, interventions and supports for caregivers of advanced kidney disease patients.
This systematic review aims to critically evaluate the methodological quality of existing research that centres on the measurement properties of tools that have been developed to assess caregiver burden in patients with advanced kidney disease. There is a need to standardise a validated clinical tool for assessment of caregiver burden in this area. Findings from this review could advance clinical research in the field of caregiver burden in patients with advanced kidney disease. Through identification of a validated clinical tool that could be applied uniformly across different clinical and research settings, the consistency and comparability of research findings in this area may be improved on.
The findings of this systematic review will be reported in accordance with the PRISMA guidelines. The PRISMA framework ensures transparent reporting of the review process, including study selection, data extraction and assessment of methodological quality. Adherence to these guidelines will enhance the transparency and reproducibility of results from this systematic review. Results from this review will guide the study team in planning future prospective and randomised studies in the field of caregiver burden in patient with advanced kidney disease.
There are some limitations associated with this review. First, the inclusion of studies that are published in English only introduces a form of language bias. Such a limitation is especially relevant given the cultural contexts and adaptation of instruments used in the assessment of caregiver burden. Second, the exclusion of certain types of study, such as unpublished data, may further limit the scope of the review. Despite efforts to conduct a comprehensive search, some relevant studies may still be omitted inadvertently. However, adherence to a rigorous methodology and deployment of a systematic search strategy should minimise the impact of such limitations.

Stress and your body, part 1.
Stress is a term commonly used everyday, it is usually considered a negative concept that has some impact on one's mental or physical wellbeing, but it can be either the cause or the effect.
In nature most processes strive to maintain equilibrium, a steady state of balance, this includes our body on a physical level (our bones and muscles) as well as a physiological level (our organ systems). Environmental factors, internal or external stimuli, continually disrupt this balance, and these factors can be interpreted as stress.
As a chiropractor I am constantly dealing with and correcting the effects of physical stress. These physical stresses include falls and bumps, lifting or carrying heavy loads, prolonged periods of time in poor chairs, unsupportive mattresses or bad shoes, sustained posture, repetitive work or changes in our body for which it must compensate such as pregnancy or a broken bone in the foot, or knee surgery. On a physical level it is often clear to see how these stresses impact us and our wellbeing.
What is not always easy to see is how Emotional stresses impact our body and our wellbeing. I estimate that close to 75% of problems I see in clinic are due either directly or indirectly to emotional stress, but when I say that, people often can't understand how emotional stress can affect us physically. It can be easier to understand when you consider situations of extreme stress, such as if your life were in danger.
In such a situation you would be feeling alot of emotions such as fear and panic, but your body would also be reacting, in a way that is known as a fight or flight reaction. This means that your body is getting prepared to fight or to flee. There are several things that happen but probably the most obvious sign would be that your heart would begin racing, this would result in you sweating, your body will produce adrenaline,which would make you feel buzzy or nervy. Your pupils will dilate, your blood will be directed to areas of your body that are important for fighting or fleeing (such as your muscles, your lungs and your brain) and away from areas that are not needed for the moment (such as your digestive organs). So you can see that emotions go hand in hand with physical changes.
Thankfully, it is not that common for us to be in a situation that is life threatening, but our modern lifestyles do entail alot of stress, and our bodies are constantly reacting to this stress in many ways, at a low level. These reactions will impact on our bodies in a physical way. Stress and your Body Part 2 will detail signs and symptoms your body may show in response to common low level daily stresses. |
Astragalus (Huang Qi) is a plant native to Asia. The Chinese name of the herb, huang qi, means "yellow leader", because the root is yellow and it is considered to be one of the most important herbs in traditional Chinese medicine. The part of the plant used medicinally is the root.
In traditional Chinese medicine, astragalus is usually made into a decoction - the roots are boiled in water then removed. It's often combined with other herbs, such as ginseng. Astragalus can also be found in supplement form at some health food stores.

The motor windings can be divided into concentrated windings and distributed windings. In the case of distributed windings, the windings are always wound on at least two stator teeth. On the other hand, in the case of concentrated windings, only one stator tooth is wound.
Both types of windings have different advantages and disadvantages, and when to use concentrated windings and when to use distributed windings depends on the size of the motor and its application.
The number of slots and the way the motor is manufactured also affects the choice of winding type. Features important to winding design are fractional slot windings and integer slot windings, as well as single-layer windings and double-layer windings.
This article aims to delve into the disparities between concentrated and distributed windings, elucidating their characteristics, applications, and technical variances.
Concentrated Windings
Concentrated windings involve winding the stator around a single tooth, simplifying the manufacturing process significantly. This approach results in minimal winding heads at the motor's top and bottom, leading to lower ohmic losses, particularly at lower speeds.
Advantages of Concentrated Windings
Simplified manufacturing process due to winding around a single tooth.
Reduced ohmic losses, especially at lower speeds.
Well-suited for short, large-diameter electric motors like hub motors in electric bicycles.
Disadvantages of Concentrated Windings
Concentrated windings are more localized and don't cover the entire core periphery which can lead to a less uniform magnetic field.
Higher harmonic losses, particularly at higher speeds.
Potential torque ripple issues, which can be addressed through rotor design modifications.
Distributed Windings
On the contrary, with distributed winding, at least two teeth of the stator are always wound, and the number of teeth wound is called the coil pitch or step size, although 3, 4, 5, or more teeth can also be wound. The coil span depends on the number of teeth on the stator and the number of pole pairs on the rotor.
In distributed winding, the windings overlap at the top and bottom of the motor. This area of the motor is also called the winding head. Due to the overlap, the winding heads in distributed windings are larger than those in concentrated windings.
Advantages of Distributed Windings
Smooth sinusoidal back electromotive force (EMF), reducing harmonics and losses.
Higher efficiency, making it suitable for applications such as electric vehicles.
Low torque ripple and noise, ideal for precision applications like machine tool spindles.
Disadvantages of Distributed Windings
Increased winding losses in very short electrical machines due to overlapping windings.
Technical Differences
The primary technical difference between concentrated and distributed windings lies in the nature of the back EMF. Concentrated windings generate a trapezoidal back EMF, resulting in higher torque but increased losses.
Conversely, distributed windings produce a smoother sinusoidal back EMF, leading to higher efficiency, particularly crucial in applications like electric vehicles.
The choice between concentrated and distributed windings depends on various factors, including motor size, application requirements, and efficiency considerations. While concentrated windings offer simplicity in manufacturing and higher torque capabilities, they come with increased losses.
Distribution windings, though more complex to manufacture, provide smoother operation, higher efficiency, and reduced torque ripple, making them indispensable for precision and energy-efficient applications. |
Python and Go (also known as Golang) are both popular open-source programming languages used for a variety of applications like web development, data analysis, artificial intelligence, and more. However, they have key differences in their design philosophy, syntax, performance, use cases and more.
This comprehensive guide examines the key similarities and differences between Python and Go to help developers select the right language for their needs. It provides a high-level comparison of Python and Go covering syntax, speed, scalability, use cases, community support and more. Concrete examples and code snippets in both languages illustrate the key concepts and differences. The guide also offers practical tips for deciding when to use Python vs Go based on factors like application requirements, developer experience level, project scope and team composition.
Python is a high-level, general-purpose programming language that emphasizes code readability and developer productivity. Created by Guido van Rossum in 1991, Python has a simple syntax similar to everyday English, with code blocks indicated by indentation rather than brackets. It supports multiple programming paradigms including object-oriented, imperative, functional and procedural styles.
Python is interpreted, dynamically typed and garbage-collected. It comes bundled with extensive standard libraries for tasks like web development, numerical computing, machine learning and more. Python powers many popular frameworks like Django (web), TensorFlow (machine learning) and PyTorch (deep learning).
# Simple Hello World program in Python
print("Hello World!")
Go (Golang)
Go is an open-source programming language launched by Google in 2009. Designed by Robert Griesemer, Rob Pike and Ken Thompson, Go aims to combine the ease of programming of interpreted languages with the performance and safety of compiled languages.
Go is statically typed, compiled and uses a C-style syntax with brackets instead of indentation. It provides built-in concurrency support through goroutines and channels. Go code can be compiled to standalone binary executables for multiple platforms.
// Hello World program in Go
package main
import "fmt"
func main() {
fmt.Println("Hello World!")
Key Differences
Programming Paradigms
Python supports imperative, object-oriented and functional programming styles. It has a simple, beginner-friendly syntax suitable for scripting.
Go is strongly typed and focuses on simplicity, pragmatism and concurrency support. It supports structured, imperative programming but not object-oriented or functional styles.
Static vs Dynamic Typing
Python is dynamically typed, allowing variables to be assigned values of any type without declaration. Types are checked during runtime which provides flexibility but can cause errors.
# No type declarations needed in Python
count = 5 # Integer
count = "5" # Changed to string
Go is statically typed like Java or C#, requiring explicit variable type declarations. This catches errors during compilation but can sometimes feel restrictive.
// Variables must be explicitly typed in Go
var count int = 5
count = "5" // Compile error - type mismatch
Compiled vs Interpreted
Python code is interpreted and executes line-by-line. The interpreter reads each line, compiles it to bytecode, and immediately executes it. This allows for rapid prototyping and development.
Go is a compiled language. The compiler converts the entire program into machine code before execution. Compiled code runs faster but initial compilation can be slower.
Speed and Performance
Go code runs much faster than Python. Benchmark tests typically show Go performing 2x-10x faster than Python. This speed advantage comes from static typing, compilation and built-in concurrency support.
Python's dynamic nature causes some runtime overhead during execution. It can be slower for CPU-bound applications but performance depends greatly on code optimization.
Concurrency Support
Go has built-in concurrency support through goroutines (lightweight threads) and channels (for communication). This makes it easy to write highly concurrent programs optimal for multi-core machines.
Python's concurrency support through threads and multiprocessing modules is more limited. Concurrent operations require more manual synchronization and shared memory management.
Syntax and Readability
Python uses significant whitespace for code blocks, while Go relies on C-style brackets {}
. Python's English-like syntax is often considered easier to read and understand for beginners.
Go's syntax is similar to C/C++ without much boilerplate. Fans argue Go's stricter rules promote consistency across codebases.
Developer Productivity
Python has extensive libraries and simple syntax that boosts developer productivity. Dynamically typed code takes less time to write.
Go limits some abstractions which can require more code. But static typing catches bugs earlier while compilation speeds make build/run cycles faster.
Go was designed by Google for high-performance networking and multiprocessing. Its lightweight threads make it easy to scale and optimize across cores.
Python can scale well but may require more infrastructure tuning. Some very large-scale web services use Python but performance bottlenecks can emerge under heavy workloads.
When to Use Python
Rapid Prototyping
Python's flexibility makes it ideal for creating quick prototypes and proofs-of-concept. Developers can focus on logic rather than boilerplate code.
Data Analysis and Machine Learning
Python has become the top choice for data analysis, machine learning and AI applications. Its extensive data science libraries like NumPy, Pandas, Matplotlib provide specialized tools.
System Automation and Scripting
Python is ubiquitous in Linux admin automated tasks, DevOps pipelines, testing suites. As a scripting language, it can quickly automate workflows.
import psutil
# Script to monitor CPU usage
cpu_pct = psutil.cpu_percent(interval=1)
print(f"CPU usage: {cpu_pct}%")
Web Development
Python powers many popular web frameworks like Django, Flask and FastAPI. It can be used to build sophisticated web backends, APIs and web applications.
When to Use Go
Native Compilation
Go creates standalone static binaries that can be deployed without dependencies. This makes Go well-suited for writing low-level system tools, containers, services with minimal footprint.
High Performance Computing
Go is a good choice for CPU intensive workloads like complex calculations, image processing, data compression/decompression requiring maximum speed and efficiency.
Networking and Concurrency
Go was designed for highly concurrent networking programs. Its goroutines and channels are perfect for building microservices, web servers, distributed systems.
// Concurrent web server in Go
package main
import (
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hi there!")
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
Cloud-Native Development
Go is widely used to build cloud-native, Kubernetes-ready applications. Its compilation to static binaries aids containerization and microservices architecture.
Code Comparison
Here are examples of some common programming tasks implemented in both Python and Go for a side-by-side comparison.
"Hello World"
This simple program prints out a greeting text.
# Python
print("Hello World!")
// Go
package main
import "fmt"
func main() {
fmt.Println("Hello World!")
Go needs a package declaration and import while Python just directly prints the text.
Web Server
This implements a simple HTTP web server:
# Python
from http.server import HTTPServer, BaseHTTPRequestHandler
class Handler(BaseHTTPRequestHandler):
def do_GET(self):
self.send_header('Content-type', 'text/plain')
self.wfile.write(b'Hello World!')
server = HTTPServer(('', 8000), Handler)
// Go
package main
import (
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello World!")
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8000", nil)
Go's built-in net/http
package makes the web server simpler compared to Python's more verbose implementation.
JSON Encoding
This encodes a Python dict as JSON:
# Python
import json
data = {
'name': 'John Doe',
'age': 25,
'address': {
'street': '123 Main St',
'city': 'Anytown'
json_data = json.dumps(data)
Same in Go:
// Go
package main
import "encoding/json"
type Person struct {
Name string
Age int
Address Address
type Address struct {
Street string
City string
func main() {
p := Person{
Name: "John Doe",
Age: 25,
Address: Address{
Street: "123 Main St",
City: "Anytown",
jsonData, _ := json.Marshal(p)
Go requires explicit structs to match the shape of the data while Python just encodes the nested dict directly.
Community and Ecosystem
Both Python and Go have thriving open source communities and ecosystems around them.
- Huge community of users across industries like science, finance, education, DevOps etc.
- Extensive set of mature libraries for data analysis, machine learning, web frameworks etc.
- Dominant in academia and research institutions. Significant collection of scientific computing libraries.
- Strong package management through PyPI and tools like pip, virtualenv.
- Downstream packages may have dependency issues and lack of standardization across libraries.
- Rapidly growing community of users in systems programming, cloud infrastructure, DevOps, and services development.
- Ecosystem more limited compared to Python but covers major areas including web, databases, containers, testing etc.
- Focus on producing simple, modular code encourages library reusability and consistency.
- Lack of generics support can complicate some library APIs.
- Standard dependency management through
go mod
built into language.
Python and Go offer two distinct approaches to programming. Python emphasizes developer productivity and rapid iteration through an expressive dynamic language and a large set of libraries. Go focuses on system-level performance, efficiency and scalability through its static typing, compilation and concurrency features.
For data analysis, machine learning and scripting tasks where developer speed and flexibility is vital, Python remains a solid choice. For high-performance networking, distributed systems and computationally intensive workloads, Go offers significant advantages.
Ultimately the decision depends on assessing the specific requirements of the application or system being developed and the strengths of each language. For some projects, it may be preferable to use Python for the application logic and Go for the performance-critical components.
By understanding the key differences in how Python and Go approach program construction, compilation, concurrency and more, developers can make an informed choice between the two languages and utilize their strengths based on project needs. |
"Sit a Spell"-- a friendly term tossed around, welcoming folks to have a neighborly chat on the front porch and maybe sip a little tea and visit. However, "Sit A Spell" is also the title of a podcast created by Tennessee ag extension agents, who use it to entertain and deliver information.
An open invitation to come "Sit a Spell", though technically we are on our feet-- you get the idea.
"Sit a Spell" is a podcast produced by UT Extension agents Meagan Brown, Justin Thomas, and Crystal Blankenship. During the pandemic, the agents wanted a way to deliver information about nutrition and food safety, so they started podcasting.
"We saw this renaissance of gardening, of canning, of people getting back to some old-time ways, and so we just started talking about how that was kind of our childhood and that we were interested in the heritage, and it just kind of evolved from there, talking about 'Sit a Spell,' so our first season was about food preservation," Brown explains.
Every show is on the road and here the road is Highway 411 in Madisonville, home to Benton's Smoky Mountain Country Hams.
Owner Allen Benton gave everybody a tour, sat a spell on the podcast, and generously gave away samples before departing.
Much like the old days, when sitting a spell meant some quality time in a front porch rocker, the agents wanted their show to be friendly and informative, and the response has been great.
"Anything we've done on Facebook Live in 2020 was massively popular. We've partnered with folks in Texas and we've partnered with state specialists," Thomas states. "We try to incorporate people and bring people in from all aspects so that we have a well-rounded perspective of it."
The ag campus likes to think of itself as Podcast U. The institute has about a dozen regular podcasters statewide and reaching more than 80,000 listeners every year. With many people stuck indoors these days, podcasts have an audience.
"I think that they have really had a spike in interest over the last year through the pandemic, and I think people really have an urgency to learn new things," Blankenship adds.
The agents will sit a spell at eight foodie locations, more tours, and talking this podcast season.
Podcasting is a relatively new technology, but here, capturing an age-old sentiment of good times and shared company.

Ex: How to buy $20,000 of GE Stock:
- Go to https://finance.yahoo.com/(Links to an external site.) and type GE in the search bar then select General Electric
- Make sure that the market is closed for the day (4 pm eastern time) and write down the stock price at closing. For example, GE's price at closing is $8.71.
- Then divide your $20k by $8.71 to find out how many shares you can buy. (20,000/8.71=2,296.21)
- As you can see, there are 21 cents left. Now, multiply your share price by the shares without the decimal point. (that's $19,998.16 so the group has some leftover money (in this case $1.84)). When stock prices are in the hundreds of dollars, you may have a lot more money to invest. What you can do now is to add the leftover amount for all five companies and buy extra shares on any of your five companies.
I hope that makes sense. Please reach out if you need clarifications!

Which Montana City Has The Best Street Art?
We always appreciate the dedication and creativity displayed by some street art pieces.
When people think of street art, they think about graffiti tags or derogatory words on the side of cars, buildings, or rail cars, but that's not always the case.
Street art can display beautiful murals of people, places, or otherworldly ideas and can be breathtaking. Some street art takes up a small wall, or some folks can turn an entire side of the building to make it more pronounced and a center point.
You mostly see fantastic street art pieces in major American cities and not in places like Montana, but you would be wrong.
A few Montana cities have street art pieces or locations, where artists can display their artwork or skills.
You won't see street art in places like Bozeman or Billings, but two towns in Montana seem to encourage unique street art.
One spot is Missoula. Missoula has places around the city where artists can display graffiti, murals, and other art exhibitions. You can find these spots in downtown parks and alleyways.
The other city that might surprise you with unique street art is Great Falls. Located in Northern Montana, Great Falls has been trying to make their downtown area more attractive and recently had an idea.
They invited world-class street artists to create fascinating and eye-catching murals on the side of buildings. Great Falls even has a walking tour to see every piece.
Remember, one of the best artists in the American West is from Montana and has a museum in Great Falls. Art and Montana have a deep history. It doesn't matter if you are a street artist or use a canvas because you can be successful or find a place to show off your skills.

Rep. Cartwright, Colleagues Introduce Time Off to Vote Act
Washington, D.C.,
April 11, 2022
Washington, D.C. – Today, U.S. Representative Matt Cartwright (D-PA-08) and U.S. Representatives Cheri Bustos (D-IL-17), Nikema Williams (D-GA-05) and Andy Levin (D-MI-09) introduced the Time Off to Vote Act, which would require employers to provide their employees at least two hours of paid leave to vote in a federal election. During each election, many wage earners choose not to go to the polls because they simply cannot afford to take time off from work. Despite this, in 2020, only 23 states and D.C. guaranteed workers some form of paid time off to head to the polls. "Voting should not be a luxury that only the well-off can afford," said Rep. Cartwright. "This bill, which ensures that American workers can cast their ballots without risking their paychecks, is an important addition to the critical voting rights legislation passed by the House earlier this year." "The freedom to vote is sacred, and the foundation of our nation's democracy," said Rep. Bustos. "I'm proud to join Congressman Cartwright today to introduce the Time Off to Vote Act, critical legislation to ensure that every American worker has the ability to exercise their constitutional right to vote. Especially as states move to restrict access to the ballot box, we must take action to protect our democracy and the voters who make it strong." "No one should be forced to choose between earning their full paycheck or participating in our democracy. As a working mom, I know how tough it is to carve out time to vote between the demands of work, family, and life. This November, Georgia will once again be the center of the political universe. In the last two elections, countless Georgians waited in line for hours to vote. Many waited all day. The Time off to Vote Act will make it easier for working people to exercise their sacred right to vote. Everyone deserves free and fair access to the ballot box, regardless of where they work or their flexibility while on the clock," said Rep. Williams, Co-Chair of the Congressional Voting Rights Caucus. "It's incredibly important that America's workers have an unbridled ability to vote in any local, state or federal election. By mandating paid leave on election days, this bill would ensure no worker has to sacrifice their wages or jeopardize their job security to exercise their sacred right to vote," said Rep. Levin. "We need to be doing all that we can to make it easy for American workers to exercise their civic duty, and I am proud to partner with my colleagues to do just that." This legislation has received the support of the American Federation of Government Employees (AFGE); Asian Americans Advancing Justice – AAJC; Brennan Center for Justice; Care in Action; Common Cause; End Citizens United/Let America Vote Action Fund; Georgia Association of Latino Elected Officials (GALEO)/GALEO Impact Fund; Lawyers' Committee for Civil Rights Under Law; The Leadership Conference on Civil and Human Rights; League of Conservation Voters (LCV); Mexican American Legal Defense and Educational Fund (MALDEF); NAACP Legal Defense and Educational Fund, Inc.; National Association of Social Workers (NASW); National Education Association (NEA); Service Employees International Union (SEIU); UNITE HERE; Vote.org; Voters of Tomorrow. "All Americans deserve to have their voices heard and votes counted. Especially as some states pass discriminatory voter suppression laws, the Time Off to Vote Act is needed more than ever," said Sylvia Albert, Director of Voting and Elections at Common Cause. "We commend Representative Cartwright for his leadership to protect and strengthen the freedom to vote so that 'We the People' can continue to have our voices heard." "As another important federal election fast approaches, Black and Brown Americans face the greatest assault on the freedom to vote since Jim Crow," said Adam Lioz, Senior Policy Counsel for the NAACP Legal Defense and Educational Fund, Inc. "The Time Off to Vote Act is a strong addition to critical voting rights legislation the House has already passed this year. Congress must stay laser focused on delivering essential protections voters need and deserve, and must pass the full package without delay." "Too many voters in this country have to work when the polls are open. This is a huge deterrent to participating in democracy," said Sean Morales-Doyle, Acting Director, Voting Rights & Elections Program at the Brennan Center. "These voters should not have to choose between casting a ballot and collecting a paycheck. The nation needs the Time Off to Vote Act." "No American should face the choice between earning a paycheck and exercising their right to vote. But because we do not guarantee Americans time off to vote, many face just this choice," said AFGE. "AFGE represents thousands of employees who work long hours, scores of frontline workers on shifts around the clock, and even more who work far from home and endure long commutes. The 'Time Off to Vote Act' will help to ensure these employees are not prevented from exercising their right to vote because their work schedules make it difficult to get to the polls on election day. We support the 'Time Off to Vote Act' and look forward to its passage so that federal employees may more fully participate in our democracy." "LCV applauds Congressman Cartwright's vital proposal to ensure that every eligible voter is able to get to the polls regardless of their work schedule, without fear of retaliation or lost wages," said Doug Lindner, Advocacy Director for Judiciary & Democracy, League of Conservation Voters. "Voting is a right, not a privilege, and the Time Off to Vote Act is a long-overdue step in protecting it." "The right to vote is sacred and nobody should be prevented from participating in our democracy because they can't get time off work to do it. We applaud Congressman Cartwright for his commitment to voting rights and fully support his Time Off to Vote Act," said Tiffany Muller, president, End Citizens United / Let America Vote Action Fund. "When working people are forced to choose between standing in a long line to vote or getting paid, our democracy suffers. As Republican lawmakers in states like Georgia, Arizona, Texas, and Wisconsin shamelessly attempt to further restrict the voting rights of Black, Latinx, Asian Pacific Islander, and indigenous people, it is imperative that Congress pass the Time Off to Vote Act," said SEIU. Working people turned out in record numbers in 2020, and we will do it again this fall. We know that when voting rights are under attack so is our ability to expand access to care, create good, union jobs, build a pathway to citizenship, address climate change and reimagine our justice system." "Vote.org, through its Electionday.org program, has worked with more than a thousand companies, representing an estimated 1.8 million workers, to ensure all workers, including full time, part time, and contract workers, get the paid time off they need to participate in democracy," said Andrea Hailey, Vote.Org CEO. "With rapidly changing rules and deadlines in all 50 states, it's high time that paid time off to vote became public policy. Nobody should have to choose between a paycheck and a vote." "For too long, women of color have faced barriers that threaten to shut us out of the electoral process. So many women of color workers, like domestic workers -- the nannies, house cleaners, and home care workers who work in their employers' homes -- face the challenge of working in jobs where they don't have paid time off, job security or flexible hours. The Time Off to Vote Act would ensure that this important segment of the electorate can fully take part in our democracy, have their voices heard and votes counted. No one should have to choose between a paycheck and their voting rights, and nothing should make it difficult for us to vote, including our jobs," said Ai-jen Poo, Senior Advisor to Care in Action. "Latino voters are much more likely to experience polling locations with long lines, extended waiting times, malfunctioning voting equipment, and unexpected closings. Legislation that requires employers to grant employees time off for voting is a step in the right direction to ensuring that Latino voters are not disenfranchised at the voting booth," said David Garcia, Director of Policy and Advocacy for Georgia Association of Latino Elected Officials (GALEO) & GALEO Impact Fund. This legislation is co-sponsored by U.S. Reps. Earl Blumenauer (D-OR-03), Brendan Boyle (D-PA-02), Cheri Bustos (D-IL-17), Andre Carson (D-IN-07), Matt Cartwright (D-PA-08), Sheila Cherfilus-McCormick (D-FL-20), Yvette Clarke (D-NY-09), Steve Cohen (D-TN-09), Diana DeGette (D-CO-01), Suzan DelBene (D-WA-01), Dwight Evans (D-PA-03), Ruben Gallego (D-AZ-07), Raúl Grijalva (D-AZ-03), Hank Johnson (D-GA-04), Mondaire Jones (D-NY-17), Ann Kirkpatrick (D-AZ-02), Barbara Lee (D-CA-13), Andy Levin (D-MI-09), Alan Lowenthal (D-CA-47), Jim McGovern (D-MA-02), Gwen Moore (D-WI-04), Eleanor Holmes Norton (D-DC-At Large), Ilhan Omar (D-MN-05), Katie Porter (D-CA-45), Lucille Roybal-Allard (D-CA-40), Michael San Nicolas (D-Guam-At Large), John Sarbanes (D-MD-03), Jan Schakowsky (D-IL-09), Adam Schiff (D-CA-28), Terri Sewell (D-AL-07), Dina Titus (D-NV-01), Rashida Tlaib (D-MI-13), Nydia Velazquez (D-NY-07), Debbie Wasserman Schultz (D-FL-23), Bonnie Watson Coleman (D-NJ-12), Nikema Williams (D-GA-05), Frederica Wilson (D-FL-24).

The faint smell of smoke lingers in the narrow path between shelters and stalls towards the site of the massive fire that destroyed nearly 900 homes at the start of the year. Rounding the corner, the source becomes evident. A break in the tree line reveals an expansive, blackened stretch of land. The hills that were once covered in greenery are now punctuated by the charred remains of trees.
Thousands of Rohingya refugees sheltered here have lost everything, yet again, on that fateful night of January 7. Their homes were simple tarpaulin and bamboo shelters, containing their few possessions collected over the years in the refugee camp -- all lost in the flames, as they scrambled up the hill to safety. Their return was rapid too. They now sit in makeshift shanties on their plots, eager to rebuild on the ground where their homes once stood. The emergency shelters and communal housing offered by humanitarian agencies may be warmer and sturdier, but many chose to stay in the same familiar space. As one affected resident put it, "We are tired of being displaced. For now, this is our home."
In this barren landscape, one can hear the clang and clamour of tools and shouts of workers with shelters materializing all around. It is evident that the Rohingya people have built and rebuilt again -- a testament to the sturdy resilience of this community.
What fills us with pride is the determination and professionalism demonstrated by the refugee volunteers and the community itself in the rapid response so crucial to mitigating such a calamity. Not a single human life was lost or seriously injured in this fire. When the first sirens blared just after 1am, hundreds of volunteer firefighters in the area sprang to action, evacuating the 5,000 people in the valley to safety — children, elderly and people with disabilities -- while simultaneously fighting the flames.
Other volunteers came across the hills from other camps, towards the fire that devoured as it sped. They knew well the speed at which such fires can spread across shelters in the dry season, aided by strong winds. Their homes could easily have been next. Three hours after it started, and thanks immensely to the Bangladeshi firefighters who arrived from the closest town, the odds turned in their favour and the flames retreated.
I am in awe of the bravery and swift action of the community. Rescue volunteers recall carrying out elderly neighbours unable to walk. Others were in charge of firebreaks, demolishing shelters to create open spaces to stop the fire from spreading. Each played a crucial role in the response.
They all agree that better access roads to the site would have saved precious time.
When the refugee camps in this valley materialized in late 2017, soon after the Rohingya's arrival, the green wetland was quickly transformed into congested clusters and neighbourhoods. In those first weeks and months, as the camps welcomed and accommodated growing numbers, Bangladeshi and international humanitarian actors worked towards the rapid establishment of a settlement that rivals San Francisco or Amsterdam in population size.
By the time the camp-wide road network was established in later years, shelters already occupied most of the hillsides. Connecting the area with a wider access road would have required demolishing homes and relocating families. So, the shelters stayed; the road was never built. This meant that, on the night of the January 7 fire, access to the valley was limited to a path and paved stairs. Narrow alleyways fortified with bamboo further reduced access to the firefighting vehicles.
There have been major upgrades to the camps since 2017: Hygiene, learning and medical facilities have improved the quality of life. Intense re-greening efforts have returned the brown expanse to lush and shaded greens. Skills development and resilience projects have established structure and belonging. And although almost everyone we speak with expresses a continued desire to return home to Myanmar when it is safe, they have nonetheless tried to incorporate a sense of normalcy and routine within their lives in asylum.
Together with Bangladeshi humanitarian actors, UN agencies and NGOs, UNHCR is rebuilding the destroyed camp with the goal of improving where we can. A better planned camp is less vulnerable to calamity. Though the temporary materials used to build the shelters remain the same, we are making critical improvements -- regarding site planning, width of the roads, hygiene facilities, street lighting and overall shelter layout.
Devastating fires in the camps are stark reminders that, while the resilience of the Rohingya may be strong, natural disasters affecting their camps expose weaknesses in camp life. It is essential that we make collective efforts to invest in key improvements to support these communities, such as better access roads and more resilient shelters that can withstand cyclones, monsoons, fires and landslides.
The hundreds of shelters, paths and facilities now being rebuilt are the hallmarks of a community being restored. Where people will welcome back their neighbours into newly built homes. And where, we hope, people will be able to sleep a bit more soundly knowing that help can reach them sooner if they need it.

The cycle of job creation doesn't stop after completion. A new development also drives indirect employment opportunities generated from industries attracted or related to the development.
Such is the case for Hudson Yards, New York City's 28-acre mixed-use development and considerably the United States' biggest megadevelopment in history. It had created thousands of construction jobs that resulted in transforming Manhattan's iconic skyline and becoming home to diverse shops, offices, cultural institutions, and hotels and residences. Ongoing operations and management of these facilities are expected to contribute to its large-scale economy, such as hosting over 55,752 workers daily and about $19 billion annually to the city's GDP.
Dubai and Songdo IBD: Creating economic opportunities afresh
Meanwhile, cities like Dubai and Songdo International Business District (IBD) generate jobs by creating economic opportunities from the ground up. They used land reclamation as an urban development strategy to address land scarcity and high population density challenges.

We all want to look and feel our best. Yet, there are times when we glance in the mirror and notice a few more lines and wrinkles than we remember. Wrinkles are a normal part of life, a sign that we've lived and laughed. But there are times when those wrinkles show up a bit earlier than we'd like.
Have you ever wondered if your daily habits could be playing a role in the appearance of wrinkles? The answer is a resounding yes! Let's dive into the culprits that can make wrinkles more noticeable and see what you can do about them.
1. The Sun: Your Skin's Adversary (and how to fight back)
Imagine you're out on a glorious summer day basking in that sunshine. While a little Vitamin D is always a good thing, spending too much time soaking in those rays can spell trouble for your skin. Those ultraviolet (UV) rays are a major enemy when it comes to wrinkles, as stated in this article from the Better Health Channel: "Sun exposure is the most common cause of skin damage and wrinkling."
Here's why: UV light breaks down the collagen and elastin in our skin. Those are the super important proteins that keep everything firm and youthful-looking.
So how do you win this battle?
- Sunscreen is the best offense: It's like putting on a shield of protection. Choose a broad-spectrum sunscreen with SPF 30 or higher and apply it every single day, even when it's gray and cloudy.
- Cover up in style: Hats, sunglasses, and lightweight, sun-protective clothing are your fashionable allies in the fight against wrinkles.
- Embrace the shade: When the sun is at its strongest midday hours, try to seek shade to give your skin a break.
2. Smoking: A One-Two Punch for Your Skin
Just when you needed another reason to give up smoking – it's terrible for your complexion! Smoking damages the delicate tissues within your skin and hampers blood flow. The result? Wrinkles show themselves much too early, and your skin loses its healthy glow.
Remember, quitting smoking is one of the best things you can do for your skin and your overall health. It won't be easy, but it'll be worth it! Here's where you can get help, guidance, and tons of support while you beat this habit for good.
3. Sleepless Nights: When Beauty Sleep Isn't Happening
I know how it feels when my toddler wakes me up, yet again, in the middle of the night. The result is not-so-pretty dark circles and an extra crease or two. It turns out that lack of quality sleep messes with your body's production of collagen – that magic protein we talked about earlier.
Getting enough snooze time helps your skin naturally rejuvenate itself. If poor sleep is the culprit, try these tips:
- Regular routine is key: Aim for a consistent bedtime and wake-up time, even on weekends.
- Dark and dreamy: Make your bedroom as dark, quiet, and cool as possible.
- Skip the late-night snacking: Heavy meals or alcohol before bed can disrupt your sleep.
4. Beware of the Wrinkle Pillow
Did you know you might be sleeping yourself into wrinkles? Dr. Erum Ilyas, a dermatologist, explains it well in the TODAY article, "[sleeping on your side or face down] can create a crushing effect on your skin for a prolonged period of time".
It's funny – some of the deepest wrinkles I have are on my left cheek from sleeping on that side. The good news is, once you realize the problem, it's fixable! Here's how:
- Back is best: Do your best to train yourself to sleep on your back. This minimizes pressure against your face.
- Silky smooth: If back sleeping is a struggle, swap your cotton pillowcase for a silk or satin one. The smoother surface helps prevent "crushing" wrinkles.
5. Stress: It Shows on Your Face
When you feel overwhelmed, chances are it shows on your face. Ever notice how stress lines can suddenly appear when you're going through a tough time? Stress releases hormones in your body which can break down collagen and accelerate the skin aging process.
Stress management might feel impossible at times, but there are little things that make a big difference:
- Movement magic: Regular exercise does wonders for both your body and mind.
- Breathe: Taking a few deep breaths in moments of stress can truly help center you.
- Mindfulness or meditation: Even a few minutes of mindful reflection a day can make a difference to how your body handles stress.
And remember…
A few more helpful tips to fight wrinkle formation:
- Hydration station: Staying well-hydrated helps your skin look plump and healthy.
- Fuel your body: A diet full of fruits, vegetables, and healthy fats nourishes your skin from within.
While some wrinkles are simply part of aging gracefully, taking care of your skin, body, and mind can have a major impact on how it reflects your journey through life. |

Understanding Combinatorics
Combinatorics is a fascinating mathematical discipline that plays a crucial role in understanding and manipulating data structures. By exploring the concepts of permutations, combinations, and binomial coefficients, we can gain a comprehensive understanding of combinatorics and its relation to data organization and optimization.
Permutations refer to the different ways in which a set of elements can be arranged. For example, if we have a set of three elements, A, B, and C, the permutations would include ABC, ACB, BAC, BCA, CAB, and CBA. The formula for calculating the number of permutations of n objects is n!. For larger sets, factorial notation becomes particularly useful.
Combinations involve selecting a subset of elements from a larger set without regard to their order. For instance, if we want to select two elements, A and B, from a set of three elements (A, B, C), the combinations would be AB, AC, and BC. The formula for calculating the number of combinations, often denoted as "n choose k," is n! / (k!(n-k)!), where n is the total number of elements and k is the number of elements to be selected.
Binomial coefficients are a special class of combinations that arise in the expansion of binomial expressions. They are commonly represented by the notation (n choose k) and are used to determine the coefficients of each term in a binomial expansion. Binomial coefficients have important applications in probability theory, algebraic equations, and data structures.
"Combinatorics is like the LEGO bricks of mathematics. It allows us to assemble and manipulate the building blocks of data structures, opening up infinite possibilities for efficient computation and problem-solving." – Dr. Mary Johnson

Understanding combinatorics provides invaluable insights into the structure and functionality of data structures. By harnessing the power of permutations, combinations, and binomial coefficients, we can optimize algorithms, improve searching and sorting techniques, and solve complex computational problems. Combinatorics truly uncovers the hidden patterns within data, opening up a world of possibilities for efficient data manipulation and analysis.
Combinatorics in Algorithms
Combinatorics, the branch of mathematics that deals with counting and arranging objects, plays a vital role in the world of algorithms. By leveraging combinatorial techniques, algorithm designers can solve complex computational problems and optimize the efficiency of their algorithms. Let's explore how combinatorics is integrated within various algorithms and learn how to harness its power.
When it comes to algorithm optimization, combinatorial analysis can provide valuable insights. By analyzing the combinatorial properties of the problem at hand, algorithm designers can identify patterns, symmetries, and other characteristics that lead to more efficient computational solutions. Combinatorial techniques allow algorithm designers to break down complex problems into smaller, more manageable subproblems, enabling the development of algorithms with improved efficiency.
One specific area where combinatorics shines in algorithms is in permutation and combination problems. Consider a scenario where the order or arrangement of a set of elements is of utmost importance. Combinatorial algorithms allow us to efficiently generate all possible permutations or combinations, enabling us to explore all potential solutions and make informed decisions. These algorithms leverage combinatorial techniques to eliminate redundant computations, improving the speed and efficiency of the overall solution.
Example: Traveling Salesman Problem
An illustrative example of the application of combinatorics in algorithms is the Traveling Salesman Problem (TSP). The TSP seeks to find the shortest possible route that a salesperson can take to visit a given set of cities and return to the starting city. This problem involves finding the optimal permutation of cities to minimize the total distance traveled.
Combinatorial algorithms, such as the Held-Karp algorithm and branch and bound algorithms, employ combinatorial techniques to explore all possible permutations of cities and determine the most efficient route. These algorithms intelligently prune the search space by leveraging combinatorial properties, significantly reducing the number of computations required.
Algorithm | Time Complexity | Space Complexity |
Held-Karp Algorithm | O(n^2 * 2^n) | O(n * 2^n) |
Branch and Bound Algorithm | O(n!) | O(n) |
In the table above, we compare the time and space complexities of the Held-Karp algorithm and the branch and bound algorithm for solving the Traveling Salesman Problem. These complexities highlight the impact of combinatorial techniques on algorithm performance. Despite the exponential time complexity, these algorithms offer efficient solutions to a notoriously challenging combinatorial problem.
As we can see, combinatorics is a powerful tool in algorithm design. By leveraging combinatorial techniques, algorithm designers can uncover efficient solutions to complex computational problems. Furthermore, combinatorial analysis allows programmers to optimize algorithms by understanding the underlying combinatorial properties of the problem. With combinatorics in algorithms, the possibilities for efficient computational solutions are endless.
Enumerative Combinatorics in Data Structures
Enumerative combinatorics is a branch of combinatorial mathematics that focuses on the counting and listing of distinct combinatorial objects. In the context of data structures, enumerative combinatorics plays a vital role in designing and implementing efficient systems for organizing and manipulating data.
By utilizing enumerative combinatorics, data structure designers can determine the exact number of possible combinations and permutations of elements within a structure. This knowledge is crucial for optimizing the storage and retrieval of information, ensuring that data is organized in the most effective and efficient way.
One of the key aspects of enumerative combinatorics is the concept of permutations. A permutation is an ordered arrangement of elements, and it allows for the creation of unique sequences within a data structure. This can be particularly useful in scenarios where the order of elements is significant, such as in queue or stack implementations.
Another important concept in enumerative combinatorics is combinations. Combinations are unordered subsets of elements, and they are often employed in data structures that require the selection of specific elements without regard to their order. For example, combination techniques are commonly used in hash tables and databases for efficient searching and retrieval.
To illustrate the significance of enumerative combinatorics in data structures, consider the following example:
Suppose we have a dataset containing 10 distinct elements, and we want to create a data structure that allows for the listing of all possible combinations of these elements. Without utilizing enumerative combinatorics, we would need to manually generate all possible combinations, which would quickly become infeasible for larger datasets. By leveraging enumerative combinatorics, however, we can precisely calculate that there are 1024 distinct combinations, saving us valuable time and effort in the design and implementation process.
Enumerative combinatorics empowers data structure designers with the ability to analyze and quantify the possible configurations of elements within a structure, enabling the creation of efficient and effective systems for handling data. By understanding and leveraging the principles of enumerative combinatorics, developers can optimize data organization and manipulation, ultimately improving the performance and scalability of data-driven applications.
Combinatorial Optimization in Data Structures
Combinatorial optimization is a powerful technique that applies combinatorial methods to solve complex problems within data structures. By leveraging the principles of combinatorics, this approach aims to find the best possible solutions for optimization challenges. In this section, we will explore the algorithms and techniques used in combinatorial optimization and how they contribute to efficient data structure-based problem-solving.
When dealing with large data sets and intricate structures, it is crucial to optimize operations to achieve desired outcomes. Combinatorial optimization provides a systematic way of approaching these challenges by using mathematical and algorithmic techniques to explore different combinations and permutations, ultimately identifying the most optimal arrangement.
One widely used algorithm in combinatorial optimization is the branch and bound method. This technique breaks down the problem into smaller subproblems and determines the most promising branches to pursue, effectively reducing the search space. By iteratively evaluating different combinations and pruning unpromising paths, the algorithm gradually converges on the optimal solution.
Another popular approach in combinatorial optimization is the genetic algorithm. Inspired by the principles of natural selection and evolution, this technique simulates the process of genetic variation, fitness evaluation, and reproduction within a population of potential solutions. Through successive generations, the algorithm refines the solutions and converges on the optimal combination, optimizing the data structure's performance.
"Combinatorial optimization combines the power of combinatorics with algorithmic techniques to solve complex, data structure-based problems efficiently."
Combinatorial optimization finds applications in various fields, such as logistics, resource allocation, scheduling, and network optimization. In each case, the goal is to find the optimal arrangement of elements within a data structure to maximize efficiency and minimize costs or constraints.
Here is an example of the application of combinatorial optimization in data structures:
Data Structure | Problem Statement | Optimization Technique | Results |
Traveling Salesman Problem | Find the shortest route to visit multiple cities | Branch and Bound | Optimal route with minimal distance |
Knapsack Problem | Select items to maximize the value within weight constraints | Genetic Algorithm | Optimal selection of items with maximum value |
Job Shop Scheduling Problem | Assign tasks to machines to minimize completion time | Branch and Bound | Optimal schedule with minimized completion time |
These examples illustrate how combinatorial optimization techniques can be applied to solve real-world problems within various data structures. By combining combinatorics and optimization algorithms, organizations can enhance the performance of their data-driven operations and achieve optimal results.
Graph Theory and Combinatorics
Graph theory and combinatorics have a strong relationship, with graph-based data structures benefiting from combinatorial analysis and algorithms. By understanding the interplay between these two fields, we can unlock powerful insights and solutions for various data manipulation challenges.
Graph theory involves the study of graphs, which are mathematical structures consisting of nodes (vertices) connected by edges. Combinatorics, on the other hand, focuses on counting, arranging, and selecting objects. When applied to graph-based data structures, combinatorial analysis techniques can help optimize their performance and efficiency.
One of the key concepts in graph theory is the representation of relationships and connections through graphs. Combinatorial analysis allows us to explore the possibilities and combinations within these relationships, providing valuable insights into data connectivity and patterns.
Combinatorial algorithms are particularly useful in solving problems related to graph traversal, pathfinding, and network optimization. By leveraging combinatorial techniques, we can efficiently explore and analyze large graphs, leading to more effective data structure designs and algorithms.
Furthermore, combinatorics enables us to examine graph properties such as connectivity, coloring, and Hamiltonian cycles. These properties have real-world applications, ranging from social network analysis to route planning and resource allocation.
"Combinatorial analysis allows us to unlock the hidden potential of graph-based data structures. By delving into the power of combinations and permutations, we can uncover efficient solutions for complex data manipulation challenges."
By combining graph theory and combinatorics, we can gain a deeper understanding of complex data structures and develop innovative algorithms to tackle intricate computational problems. Whether it's optimizing network connectivity or analyzing social relationships, the synergy between graph theory and combinatorics opens up a world of possibilities.
Combinatorics in Hashing and Searching
Hashing and searching operations are fundamental components of efficient data structures. By incorporating combinatorial techniques, the performance of these operations can be significantly enhanced. Combinatorics, a branch of mathematics that deals with counting, arranging, and selecting objects, provides valuable insights and methods for optimizing hashing and searching algorithms.
Combinatorics in Hashing
Hashing is a widely used technique for efficient data retrieval. It involves mapping data items to unique positions in a data structure called a hash table. Combinatorial analysis plays a crucial role in designing hash functions, which determine the mapping of data items to these positions. Through the use of combinatorial techniques, such as permutations and combinations, hash functions can be designed to minimize collisions, ensuring that data items are evenly distributed and easily accessible.
Hashing in data structures is like a well-organized library, where each book is assigned a unique shelf. Combinatorics helps in designing a cataloging system that allows for quick retrieval without overcrowding any particular shelf.
Combinatorics in Searching
Searching for specific data elements within a large dataset is a common task in many applications. Combinatorial techniques, such as binary search, can significantly improve the efficiency of search operations. By dividing the dataset into smaller subsets and applying combinatorial analysis, the search algorithm can quickly narrow down the search space, reducing the number of comparisons required to find the desired data element.
Searching without combinatorial techniques is like finding a needle in a haystack. Combinatorics allows us to divide the haystack into smaller portions and devise a systematic approach to locate the needle more efficiently.
Combinatorics also plays a crucial role in analyzing the performance of searching algorithms. Through combinatorial analysis, algorithm designers can estimate the average and worst-case time complexity of different search strategies, enabling them to make informed decisions about algorithm selection and optimization.
Examples of Combinatorics in Hashing and Searching
Let's take a look at some practical examples of combinatorial techniques in hashing and searching:
- Permutations to generate unique hash keys: By permuting the characters of a data item, unique hash keys can be generated, ensuring even distribution within the hash table.
- Combinations for efficient search space reduction: Combinations can be used to divide the dataset into smaller subsets, minimizing the search space and speeding up the search process.
- Binomial coefficients for collision resolution: Binomial coefficients can be utilized to resolve collisions in hashing by determining optimal positions for data items in case of collisions.
By harnessing the power of combinatorics, hashing and searching operations can be optimized to achieve faster data retrieval, reduced search complexity, and improved overall performance.
Probability and Combinatorics in Data Structures
When it comes to designing efficient data structures, understanding the connection between probability theory and combinatorics is essential. The utilization of probabilistic combinatorial techniques can greatly enhance the effectiveness of data manipulation, leading to improved performance and optimized algorithms.
"Probability is the very guide of life." – Cicero
By incorporating probability theory into combinatorial analysis, data structures can benefit from a deeper understanding of the likelihood of different outcomes and events. This knowledge allows for the development of intelligent algorithms and decision-making processes that can adapt based on probabilistic factors.
Combinatorics provides the foundation for analyzing and manipulating discrete structures, while probability theory enables us to quantify uncertainty and make informed choices based on likelihoods. Together, these disciplines offer powerful tools for data structure designers.
Applying Probability in Data Structures
One application of probability in data structures is the design of efficient hashing algorithms.

These pollutants enter the sea and can wreak great havoc - poisoning marine life, causing the water to become cloudy so that light cannot reach the algae. They stop producing oxygen and this makes the life very difficult for marine animals. |
Delivering medical imaging equipment to the top of the world is not for the faint of heart. Capital Enterprises, a Carestream distributor, transported and installed a Carestream Vita Flex CR system that provides imaging services to 8,000 local residents, as well as mountaineers, sherpas, and others who support those who dare to climb Mount Everest.
The Kunde hospital is located 24.6 kilometers (15.3 miles) from Mount Everest Base Camp. The imaging system was transported by plane to Lukla, Nepal, which is ranked as the world's deadliest airport due to its high elevation and unforgiving terrain. From there, porters carried the x-ray equipment on their backs for 30 kilometers (18.6 miles) to the hospital, which is staffed and operated by local physicians and nurses.
For centuries, Mount Everest has captured the human imagination. Mount Everest is 29,035 feet or 8,848 meters high and is estimated to be more than 60 million years old.
The Carestream Vita Flex CR system is used by medical staff to capture digital x-ray images of shoulders and extremities that have been broken or sprained; the head and neck area to diagnose sprains or concussions; as well as chest exams that may indicate a patient has pneumonia, altitude sickness, or evidence of a heart attack or other serious medical conditions.
"These imaging studies are essential to diagnosing diseases and injuries to climbers, sherpas and other workers at base camp," says Charlie Hicks, Carestream's general manager of global x-ray solutions. "The images are available in minutes, and physicians decide if a patient can be treated at the hospital or must be transported to Kathmandu by helicopter or airplane."
Kathmandu is 136 kilometers (85 miles) from Kunde hospital. The Kunde hospital is located at 3,840 meters (12,600 feet) above sea level and was founded by Sir Edmund Hillary in 1966. |

What are the benefits of using a Sauna?
Introduction - Even now, people still like using saunas, which have been around for thousands of years. People can relax and unwind in a sauna, and it might also be good for their health.
Therapy has always involved using sweating. Sweat rooms were utilized by the Mayans 3,000 years ago, claims Harvard Health Publications. 1 in 3 Finns still utilize saunas, which have been used for hundreds of years. It's estimated that there are more than a million saunas in the United States (U.S.).
Rejuvenation and cardiovascular health are the two key advantages of saunas.
You may well have heard that entering a steamy sauna after working out at the gym might help your body detoxify and unwind.
For hundreds of years, Scandinavians have been utilizing saunas for purification, leisure, and weight loss. Early childhood is when Scandinavian countries introduce sauna use
The results of recent studies on sauna advantages are conflicting. Make sure to assess your unique health requirements first if you're considering including the sauna in your health and fitness regimen, and Shop saunas online.
Saunas vs. Steam Rooms -
You might be asking what distinguishes a steam room from a sauna. Although they employ various forms of heat, both kinds of chambers are used to encourage perspiration.
Saunas employ dry heat from a fireplace or hot rocks to raise the room's temperature to 195°F (90.5°C) while maintaining a very low humidity level.
On the other hand, steam rooms generate heat through the application of moisture. They typically operate between 110 and 120 °F (43 and 49 °C) and 100 % relative humidity, which are lower temperatures.
The benefits of Saunas -
Your skin temperature increases, your heart rate jumps, and your blood vessels dilate more when you enter a sauna. As your heart starts pumping more blood, this occurs. Of course, you start to perspire as well. This experience has a few advantages.
- Relaxation - Since ancient times, people have relied on saunas to make them feel relaxed. When your heart rate elevates and your blood vessels dilate, more blood is able to reach the skin. Saunas might also promote better blood flow.
In order to keep your body's temperature balanced, your sympathetic nervous system becomes more active. Your endocrine glands start contributing to this reaction.
It's possible that your body's reaction to the heat will make you more attentive, less sensitive to pain, and even upbeat. The heat relaxes your muscles, particularly those in your neck and face. These muscles frequently become stiff at the end of the day.
One of the main advantages of using a sauna is its calming effect. While in the space, you can meditate to promote calmness further. When you take some time to relax your body, your mind and spirit often follow suit. The impact lasts for a while and might even improve your ability to sleep.
- Pain Relief - People who use dry saunas may have increased energy. In a sauna, blood circulation rises as the blood vessels calm and widen, which can alleviate tight muscles and decrease joint stress. People with arthritis and persistent pain may benefit from saunas.
An older 2008 study found that sauna sessions reduced pain, stiffness, and tiredness over the course of 4 weeks in individuals who had long-term musculoskeletal diseases, such as rheumatoid arthritis and ankylosing spondylitis.
The improvements were not determined to be statistically significant, despite the fact that all of the study's participants claimed some benefits. Before including sauna use as part of their treatment, the authors advise patients with these diseases to undergo a few trial sessions to determine whether it improves their symptoms.
- Improving cardiovascular health - A lower risk of cardiac disease may be associated with lower stress levels when using a sauna. In one Finnish study, 2,315 men between the ages of 42 and 60 were monitored for 20 years. According to research, using a sauna may reduce a person's risk of passing away from cardiovascular disease. Two to three sauna visits per week reduced the risk of sudden cardiac mortality in participants by 22% compared to one visit per week. Four to seven times per week, sauna users had a 63 percent lower risk of sudden cardiac death and a 50% lower risk of dying from heart disease than those who only used saunas occasionally.
- Alzheimer's Diseases - Two to three times per week, sauna users had a 22% lower risk of developing dementia and a 20% lower risk of developing Alzheimer's than non-users. When compared to people who used saunas only once a week, those who used them four to seven times per week had 66 percent lower odds of developing Alzheimer's disease and 65 percent lower odds of developing Alzheimer's.
- Skin Problems and Asthma - Using a dry sauna dries out your skin. While utilizing a sauna, some psoriasis sufferers may find that their symptoms lessen, and those with atopic dermatitis might discover that their condition worsens. By using a sauna, people with asthma may experience some symptom alleviation. A sauna may ease stress, release phlegm, and open airways.
Precautions -
- Avoid drinking since it raises the risk of hypotension, arrhythmia, dehydration, and sudden death. A year-long study of Finns who passed away suddenly revealed that 1.7% of those who had recently used a sauna had done so within the previous three hours, and 1.8% had done so within the previous day. Many of them had alcoholic beverages.
- Limit your time in the sauna to no longer than 20 minutes at a time. The recommended time for new users is 5 to 10 minutes. They can gradually extend the period to 20 minutes as they become accustomed to the heat.
- Whatever kind of sauna a person uses, it's necessary to replenish the fluids lost through perspiration by drinking plenty of water. After using a sauna, people should consume two to four bottles of water.
Conclusion - The effects on the body are consistent regardless of how the sauna is heated or the humidity level. A person's pulse rate rises, and their blood vessels widen while they relax in a sauna. This improves circulation in a manner comparable to light to moderate exercise, depending on how long you spend in the sauna. So, if you want to shop sauna online, you must go ahead! |
Safely dispose of corrugated metal roofing by finding recycling facilities through waste management services or roofing companies. Understand the environmental impact, prep metal sheets, consider professional removal services, and adhere to legal regulations.
Explore more options on how to dispose of corrugated metal roofing safely in our guide below.
Safe Disposal Methods for Corrugated Metal Roofing
Finding the right recycling facility for corrugated metal roofing begins with understanding the high recyclability of metal materials. Steel, for instance, boasts an impressive recycling rate that exceeds 70%.
Meanwhile, other metals like aluminum and copper are similarly sustainable, often reused with high efficiency in terms of energy and resource conservation.
To locate facilities capable of processing corrugated metal roofing, homeowners can start by using the comprehensive search tools provided by major waste management services. For example, websites like Waste Management (WM) offer user-friendly platforms where you can enter your address to find nearby drop-off locations that accept metal waste.
This search tool is invaluable for quickly identifying local recycling centers that handle metal roofing materials.
Other Resources to Look Into
Specific roofing companies often provide resources to help locate recycling centers or contractors that specialize in metal roofing. You may even find some that offer a locator tool on their website, which allows users to find both distributors and contractors who can manage the disposal and recycling of metal roofing materials.
Understanding the environmental impact of recycling metal roofing is crucial. Metal roof recycling contributes significantly to sustainability efforts by reducing the demand for raw materials.
This is not only beneficial for the environment but can also be economically advantageous due to the value recovered from scrap metal.
For those new to recycling large materials like roofing, it's important to contact multiple facilities to confirm which types of materials they accept and whether there are any preparation steps required (such as cleaning or dismantling the roofing) before recycling can take place.
Engaging with local recyclers also offers an opportunity to learn more about the recycling process and ensure that your materials are handled responsibly.
Preparing Metal Sheets for Recycling
Preparing corrugated metal sheets for recycling involves a few critical steps to ensure the material is processed efficiently and effectively.
First, it's important to remove any non-metal components attached to the metal sheets. This includes nails, screws, and any non-metallic fittings or insulation. Clearing these materials helps prevent contamination during the recycling process.
Once the metal is cleared of contaminants, it should be cut into manageable pieces if necessary. This step depends on the facility's requirements and who you're planning to send the metal to. Some facilities might accept full sheets, while others require the metal to be cut into smaller pieces to fit into recycling machinery.
Additionally, sorting the metal by type—separating steel from aluminum, for example—can be a crucial step. This is because different metals are processed in different ways and might even be sent to different recycling facilities. Sorting the metals ensures that each type can be recycled with the highest efficiency and into the highest-quality new products.
Contacting Professional Removal Services
When it comes to large quantities of metal roofing or particularly large sheets that are difficult to handle, professional junk removal services can be invaluable. These services not only help in transporting the heavy and cumbersome materials safely but also ensure that the metal is delivered to the right recycling facilities.
Professional services can be located through local business directories or by contacting local metal roofing suppliers, who often have partnerships with recycling companies and can provide recommendations.
Moreover, some removal services specialize in eco-friendly disposal and will handle the entire process, from dismantling to recycling. Just like us at EZ CleanUp, we ensure that junk disposal helps minimize its environmental impact.
Environmental Benefits of Recycling Corrugated Metal
Recycling corrugated metal significantly conserves natural resources. By reusing metals, we reduce the need for virgin materials such as iron ore, bauxite, and nickel.
Recycling metals prevents the environmentally intensive extraction of raw materials, which involves significant land disruption and energy use. For instance, producing aluminum from recycled materials uses only about 5% of the energy required to produce it from raw ore.
Reducing Landfill Waste
Corrugated metal recycling plays a critical role in reducing landfill waste. Metals have a high recycling rate, with steel and aluminum being among the most recycled materials in the world. In 2018, about 69 million tons of municipal solid waste were recycled in the U.S., with metals making up a significant portion of this.
By diverting metals from landfills, we not only conserve space but also minimize the leaching of metals into groundwater and reduce methane emissions from decomposition processes.
Lowering Energy Consumption
The process of recycling metal is far less energy-intensive than producing new metal from raw materials. Recycling steel, for example, saves 60% to 74% of the energy needed to produce it from raw materials.
For aluminum, the savings are even greater, reducing the energy needed by 90% compared to new production. These energy savings lead to lower carbon emissions. These help combat climate change.
In 2018, recycling and composting of waste saved over 193 million metric tons of carbon dioxide equivalent, which is a significant contribution to mitigating global warming.
Legal Considerations in the Disposal of Metal Roofing
The disposal of metal roofing involves various local regulations, which can significantly differ depending on the state and even the municipality. Most localities adhere to guidelines set forth by state regulations, which in turn align with broader federal mandates to ensure environmental safety and proper waste management.
It's crucial for contractors and homeowners to consult their local waste management statutes and building codes to understand specific requirements. These local laws might include specifics on how to handle the metal waste, where it can be transported, and what facilities are authorized to accept it.
Compliance with Environmental Regulations
Compliance with environmental regulations, particularly those pertaining to construction and demolition waste, is essential. The EPA and state environmental agencies have clear guidelines that regulate not just the disposal but also the recycling of materials like metal roofing.
For example, if metal roofing contains hazardous materials like asbestos, the Asbestos NESHAP regulations would dictate specific handling and disposal procedures to prevent environmental contamination and health hazards.
Penalties for Improper Disposal
Penalties for non-compliance can include substantial fines and even criminal charges in severe cases. These are imposed not just to punish but to encourage compliance with laws that protect environmental health and public safety.
The fines and the nature of any legal action can vary based on the amount and type of waste improperly disposed of and the environmental impact of the violation. Regular updates and training on current laws, such as those provided by the National Roofing Contractors Association and local environmental agencies, are essential for staying compliant and avoiding these penalties.
Step-by-Step Process for Safe Disposal
Here are the steps you need to take when disposing of corrugated metal roofing:
1. Assess the Condition of the Metal
When preparing to recycle metal roofing, the first step is to conduct a thorough inspection of the materials to check their current state and composition. This involves identifying the type of metal—such as aluminum, copper, steel, or galvanized iron—and examining the roofing for any signs of damage or contamination that could affect recyclability.
2. Identify Metal Types
It's essential to recognize the specific metals used in your roofing because different metals may require different recycling processes. Common metals used in roofing include galvanized steel and aluminum, which are highly valued in the recycling market due to their recyclability.
3. Check for Contaminants
Ensure that the metal roofing is free from non-metallic contaminants like asphalt, tar, wood, and plastic attachments. These materials must be separated from the metal, as they can interfere with the recycling process.
4. Understand Material Condition
Assess the physical condition of the metal sheets. Look for any severe corrosion or structural damage that might complicate recycling. While most metal roofing materials can be recycled regardless of their condition, knowing the extent of wear can help in determining the most efficient recycling pathway.
5. Learn about Logistics of Recycling
Consider the logistics of transporting the metal to a recycling facility. If the metal roofing is in large, unwieldy panels, it may need to be cut into smaller, manageable pieces for easier handling and transportation.
Sorting Metal Based on Type and Quality
The process starts by using a magnet to distinguish ferrous metals, which are magnetic, from non-ferrous metals, which are not. This simple test helps streamline the sorting process and ensures that each type of metal is processed appropriately for recycling.
Separate Ferrous from Non-Ferrous Metals
Utilize a magnet to identify and separate ferrous metals like steel and iron from non-ferrous metals such as aluminum and copper. Ferrous metals are typically recycled into construction materials, while non-ferrous metals can be used in a wide range of applications due to their resistance to corrosion.
Clean and Prepare the Metals
Remove any contaminants, such as paint, insulation, or fasteners. Clean metals are more valuable as they require less processing before being recycled. For aluminum roofing, ensure that the material is free from dirt and debris to facilitate the recycling process.
Sort by Alloy and Quality
Further categorize the metals by specific alloys and quality grades. Different alloys have different uses and recycling processes, so accurate sorting can maximize the value recovered from the scrap metal.
Alternatives to Disposal: Repurposing Metal Roofing
Repurposing or upcycling old metal roofing offers a sustainable way to enhance your home and garden with unique DIY projects. The durability and aesthetic appeal of metal roofing materials make them ideal for various creative uses:
- Wall Decor and Artistic Pieces: You can cut the metal into various shapes or use it as a canvas for paintings. Creatively painted or naturally weathered pieces can serve as focal points in any room or garden.

Uric acid crystals, known for their link with illnesses such as gout, can cause excruciating agony and misery in people who are affected. While conventional therapies provide relief, many people seek natural methods to manage uric acid buildup and symptoms rather than relying only on medicine. This article investigates a variety of natural methods for eliminating uric acid crystals from joints, giving information on dietary changes, lifestyle changes, and alternative therapies that may aid in the disintegration and elimination of these crystalline deposits. Individuals can empower themselves to take proactive actions toward joint health and symptom management by investigating the mechanisms underlying uric acid crystal production and examining evidence-based techniques to mitigate their impact.
Understanding Uric Acid and Gout
Gout is a kind of arthritis characterized by the accumulation of uric acid crystals in the joints. Uric acid is a waste product generally excreted by the kidneys. However, if the body creates too much uric acid or the kidneys are unable to clear it correctly, it can build up in the blood and form crystals that deposit in the joints, causing inflammation and pain.
The Role of Diet in Uric Acid Levels
Diet significantly influences uric acid levels and gout. Foods rich in purines, such as red meat, seafood, and organ meats, can raise uric acid levels in the body. Alcohol, particularly beer, can raise uric acid levels. Fructose and sugar-sweetened beverages have also been associated with elevated uric acid levels.
On the other side, a diet high in fruits and vegetables, whole grains, and low-fat dairy products may help lower uric acid levels and lessen the risk of gout.
Identifying Symptoms and Risk Factors
Gout symptoms include acute pain, edema, redness, and warmth in the afflicted joint. This is most commonly associated with the big toe, but it can also affect the ankle, knee, wrist, or fingers.
Gout risk factors include a family history of the ailment, being male, being overweight, having high blood pressure or diabetes, and eating a diet heavy in purines, alcohol, fructose, or sugar-sweetened beverages.
Finally, understanding how nutrition affects uric acid levels, as well as identifying symptoms and risk factors, can aid in the prevention and management of gout. A well-balanced diet and good lifestyle choices can significantly reduce the risk of gout while also improving overall health.
Natural Methods for Lowering Uric Acid Levels
Gout is a kind of arthritis characterized by the buildup of uric acid crystals in the joints. These crystals can cause significant discomfort and swelling, making it difficult to move the affected joint. While pharmaceuticals are available to treat gout, natural methods can also help lower uric acid levels and prevent gout flares.
Hydration and Dietary Adjustments
One of the most important things a gout sufferer can do is stay hydrated. Drinking enough water can help eliminate uric acid from the body, lowering the chance of crystal development in the joints. Additionally, making dietary changes can be useful. Eating a diet high in vegetables and fruits can help lower uric acid levels. Cherries and cherry juice are very good for gout sufferers. Coffee and vitamin C have been demonstrated to lower uric acid levels.
Incorporating Anti-Inflammatory Foods
In addition to dietary changes, including anti-inflammatory items in your diet can be beneficial. Anti-inflammatory foods include ginger, turmeric, and omega-3 fatty acids found in fish. These foods can help reduce inflammation in the body, hence reducing the intensity of gout attacks.
Herbal Supplements and Natural Substances
There are also a variety of herbal medicines and natural ingredients that can help lower uric acid levels. For example, lemon juice has been demonstrated to help neutralize uric acid in the body. Apple cider vinegar, which contains acetic acid, can also help lower uric acid levels. Celery seed extract and nettle tea are two other natural remedies that may help gout sufferers.
Overall, natural therapies can help reduce uric acid levels and avoid gout attacks. Staying hydrated and making dietary changes, including anti-inflammatory foods, as well as taking herbal supplements and natural substances, can help minimize your risk of gout and improve your overall health.
Lifestyle Modifications for Managing Uric Acid
Maintaining uric acid levels is critical for avoiding the production of uric acid crystals in the joints. While medication is often required, lifestyle changes can help lower uric acid levels and prevent gout attacks. Here are some lifestyle changes that can help control uric acid levels naturally.
Weight Management and Exercise
Keeping a healthy weight is essential for controlling uric acid levels. Excess weight can cause elevated levels of uric acid in the blood, increasing the risk of gout episodes. Regular exercise can also aid in uric acid management by encouraging weight loss and boosting insulin sensitivity.
A combination of aerobic and strength-training workouts can help manage uric acid levels. Aerobic exercises, such as brisk walking, jogging, or cycling, can help you burn calories and enhance cardiovascular health. Strength-training exercises like weightlifting and resistance training can help develop muscle, which boosts metabolism and promotes weight loss.
Stress Reduction and Adequate Rest
Stress can cause gout attacks by raising uric acid levels in the bloodstream. As a result, stress-reduction practices like meditation, deep breathing, and yoga can help control uric acid levels and avoid gout attacks.
Adequate rest is also required to manage uric acid levels. Getting adequate sleep can reduce stress and improve overall health. It is advisable to get 7-9 hours of sleep per night.
In conclusion, lifestyle changes such as weight loss, exercise, stress reduction, and proper rest can help control uric acid levels naturally. Individuals with gout who incorporate these changes into their daily routine can minimize their risk of gout attacks while also improving their overall health.
Medical Interventions and When to See a Doctor
While natural therapies can help remove uric acid crystals from joints, there are some cases where medical intervention is required. In these circumstances, it is critical to see a doctor for an accurate diagnosis and treatment.
Medications for Uric Acid Control
There are numerous drugs available to help regulate uric acid levels in the body. This includes:
- Allopurinol works by lowering the body's production of uric acid. It is usually recommended for those who suffer frequent gout bouts or tophi.
- Febuxostat: Like allopurinol, febuxostat reduces the synthesis of uric acid. It is frequently used for patients who cannot take allopurinol.
- Probenecid: This drug assists the kidneys in eliminating uric acid from the body. It is commonly recommended for those who have a history of kidney stones or who are unable to handle other drugs.
- Colchicine: This drug reduces inflammation and pain caused by gout attacks. It is frequently taken along with other drugs.
- Nonsteroidal anti-inflammatory medicines (NSAIDs) can help lessen the pain and inflammation caused by gout attacks. They are available over the counter or with a prescription.
- Corticosteroids: These drugs can help lessen the inflammation and pain caused by gout attacks. They are available as pills or can be injected directly into the afflicted joint.
Advanced Treatments and Surgery
In some circumstances, sophisticated therapies or surgery may be required to remove uric acid crystals from joints. This can include:
- Extracorporeal shock wave lithotripsy (ESWL): This treatment employs shock waves to dislodge uric acid crystals in the joints. It is frequently used for patients with big tophi that cannot be managed with medicines.
- Joint aspiration: This treatment uses a needle to extract fluid from the afflicted joint. It can help lessen the inflammation and agony caused by gout attacks.
- Surgery: In rare circumstances, surgery may be required to remove tophi or damaged tissue from an affected joint. This may be necessary if other therapies have proven ineffective.
If you have gout symptoms or a history of elevated uric acid levels, you should see your doctor. Based on your specific needs and medical history, your doctor can recommend the best course of therapy for you.
To summarize, while addressing uric acid crystals in joints is a multidimensional task, the study of natural methods offers potential options for people seeking relief from the pain and discomfort associated with illnesses such as gout. Individuals can encourage the breakdown and elimination of uric acid crystals by making dietary changes such as drinking more water, eating anti-inflammatory foods, and avoiding purine-rich foods.
Furthermore, lifestyle changes such as frequent exercise, maintaining a healthy weight, and controlling stress levels can all help to improve joint health and general well-being. Alternative therapies, such as herbal supplements and acupuncture, may support natural methods of relieving symptoms and removing uric acid crystals. While natural methods may not provide immediate relief for everyone, their potential benefits in lowering uric acid crystals deposition and increasing joint function highlight the necessity of a multifaceted approach to controlling uric acid accumulation. Individuals are encouraged to engage with healthcare specialists to create treatment regimens that are tailored to their specific requirements and preferences.

Background Initiation of antitumor immunity is reliant on the stimulation of dendritic cells (DCs) to present tumor antigens to naïve T cells and generate effector T cells that can kill cancer cells. Induction of immunogenic cell death after certain types of cytotoxic anticancer therapies can stimulate T cell-mediated immunity. However, cytotoxic therapies simultaneously activate multiple types of cellular stress and programmed cell death; hence, it remains unknown what types of cancer cell death confer superior antitumor immunity.
Methods Murine cancer cells were engineered to activate apoptotic or pyroptotic cell death after Dox-induced expression of procell death proteins. Cell-free supernatants were collected to measure secreted danger signals, cytokines, and chemokines. Tumors were formed by transplanting engineered tumor cells to specifically activate apoptosis or pyroptosis in established tumors and the magnitude of immune response measured by flow cytometry. Tumor growth was measured using calipers to estimate end point tumor volumes for Kaplan-Meier survival analysis.
Results We demonstrated that, unlike apoptosis, pyroptosis induces an immunostimulatory secretome signature. In established tumors pyroptosis preferentially activated CD103+ and XCR1+ type I conventional DCs (cDC1) along with a higher magnitude and functionality of tumor-specific CD8+ T cells and reduced number of regulatory T cells within the tumor. Depletion of cDC1 or CD4+ and CD8+ T cells ablated the antitumor response leaving mice susceptible to a tumor rechallenge.
Conclusion Our study highlights that distinct types of cell death yield varying immunotherapeutic effect and selective activation of pyroptosis can be used to potentiate multiple aspects of the anticancer immunity cycle.

Chemoradiotherapies activate the immune response, although the contribution of individual stress and cell death to anticancer immunity remains unknown.
This study shows that pyroptosis, unlike apoptosis, is an immunostimulatory type of cell death activating type I conventional dendritic cells to prime durable T cell-mediated antitumor immunity.
The implications are pyroptosis inducing agents should be further tested for development as anticancer therapies for patients with cancer.
Immunotherapy has demonstrated success in many types of human cancers.1 However, a few human cancers poorly respond to immunotherapy due to tumor intrinsic barriers of T cell priming and trafficking into the tumor or immunosuppressive microenvironment preventing cytotoxic CD8+ T cells to kill cancer cells.2 Therefore, there is a need for therapies that can subvert the intratumoral immunosuppression by reigniting the anticancer immunity cycle to elevate the magnitude and functionality of T cells within the tumor.3
Chemoradiotherapies render tumors to emit danger signals, cytokines, and chemokines thereby stimulating the anticancer immunity cycle.3 4 Collectively, these biomolecules regulate the activity of antigen presenting cells as well as the trafficking of cytotoxic T cells into the tumor.5 Indeed, chemoradiotherapies,6 photodynamic therapy,7 oncolytic viruses (OVs),8–16 and many other immunogenic cell death (ICD) inducers can modify the tumor microenvironment and often facilitate the eradication of established tumors. However, most cytotoxic anticancer treatments simultaneously activate a mixture of premortem stress and programmed cell death. Furthermore, chemotherapies directly impact the quantity and/or functionality of immune cells, complicating the interpretation of mechanisms contributing to clinical effects and outcomes driven by specific types of cancer cell stress and cell death.
Depending on the type of cytotoxic agent and cellular pathways engaged, during ICD, cancer cells can die by apoptosis,6 necroptosis,17 pyroptosis18 and ferroptosis.19 In most scenarios, cell death takes place in the background of premortem endoplasmic, oxidative, and mitochondrial stress.20 As a result, the individual contribution of premortem stress and cell death pathways to anticancer immunity is largely unknown.21 Anthracycline and oxaliplatin activate apoptosis along with autophagic stress response to emit immunostimulatory secretomes.22 Expressing procell death proteins to drive specific types of cell death is unraveling immunological outcomes.23 24 Activation of necroptosis by RIPK3 dimerization, but not apoptosis after caspase 8/9 expression, elicits potent antitumor immunity.23 24 In the same study, necroptosis driven by RIPK3 lacking RIPK1 interaction domain failed to activate NF-kb mediated inflammation and consequently failed to initiate protective anticancer immunity.23 In contrast, another study reported terminal cell lysis by expressing mixed lineage kinase domain like pseudokinase (MLKL) mRNA activated potent anticancer immunity.25 These studies highlight that so much remains unknown about how distinct types of cancer cell death can shape the overall intratumoral immune landscape and anticancer effect.
Pyroptosis is one of the immune-stimulatory cancer cell death modalities and it can be induced by chemotherapy, photodynamic therapy,18 26 and OVs,27 cytotoxic CD8+ T cells28–31 and NK cells.32 Irrespective of the type of pyroptosis-inducing stimuli and upstream signaling cascade, the cleavage of the gasdermin family of proteins by caspases and granzymes is a terminal event during pyroptosis.18 33–36
Enforced expression of full-length gasdermin E protein promotes granzyme mediated pyroptosis initiating T cell-mediated anticancer effect.28 However, detailed mechanisms by which pyroptosis modifies the tumor microenvironment and how it modulates antigen presentation to prime antitumor T cells remains unknown. Using two murine tumor models, we report that unlike apoptosis, driven by dimerizable (dd) C-terminal caspase-8 (dd-Cterm-Cas8), pyroptosis, activated by N-terminal gasdermin E (NtermGas) induced a higher amount of calreticulin on the cell surface, emitted danger signals ATP and HMGB1, as well as cytokines and chemokines. These biomolecules potently stimulated conventional dendritic cell (cDC1) and associated expansion and intratumoral recruitment of antigen-specific cytotoxic CD8+ T cells and lower amounts of regulatory T cells within the tumor thereby promoting anticancer effect and extension of the overall survival of tumor-bearing mice.
Pyroptosis emits danger signals and proinflammatory cytokines and chemokines
To define the immunological events and anticancer outcomes after induction of apoptosis and pyroptosis, we developed genetic models of rapid and synchronized cell death by inducibly expressing procell death proteins (figure 1A,D). Doxycycline (Dox) treatment activated the expression of dd-Cterm-Cas8 (figure 1B) and NtermGas (figure 1E) in mouse colon cancer (MC-38) and lung cancer cells derived from K-rasG12D p53loxP/loxP (KP) mice (KP1.9)37 (online supplemental file 2). Expression of dd-Cterm-Cas8 activated apoptosis, as evidenced by cleavage of caspase 3 (figure 1B). In addition, expression of procell death proteins, dd-Cterm-Cas8 and NtermGas showed reduced cellular metabolism used as a proxy to measure cell viability (figure 1C,F and online supplemental file 2). Pyroptotic but not apoptotic cells showed elevated surface expression of calreticulin (figure 1G) and higher amounts of danger signals HMGB1 (figure 1H), and ATP (figure 1I, online supplemental file 2) in cell-free supernatants. In addition, compared with untreated controls, pyroptotic cells emitted significantly increased amounts of proinflammatory cytokines and chemokines (IL-1β, IL-2, IL-16, IL-9, CXCL9, CX3CL1, and CCL3) and decreased of eotaxin (CCL11) and G-CSF (figure 1J and online supplemental file 3). On the other hand, apoptotic cells emitted higher amounts of cytokines and chemokines (IL-2, IL-9, IL-11, IL-20, IFN-γ, IFN-β, eotaxin, CCL10, CCL21, CCL22) (figure 1J and online supplemental file 4). Cytokines and chemokines downregulated during apoptosis include IL-1a, IL-16, LIF, G-CSF, GMCSF, CCL12, VEGF, CCL5, CCL2, CX3CL1, and KC (figure 1J and online supplemental file 4). In addition to the remarkable differences in the types of cytokine and chemokines emitted, there were notable differences in the kinetics of their secretion. Pyroptosis-induced cytokines and chemokines increased over time from 2 hours to 4 hours. In contrast, most of the cytokine and chemokines emitted during apoptosis showed transient increase at the 2 hour time point and declined by the 4 hour time point (figure 1J).

Established tumors of MC-38-dd-Cterm-Cas8 or MC-38-NtermGas expressed the procell death proteins after feeding of mice with a Dox-medicated diet (figure 2A,B). Analysis of 44-plex cytokines/chemokines in pyroptotic tumor homogenates showed significant increase in IL-1a, IL-6, IFN-β, IL-16, CXCL2, CCL21, and CCL22 (figure 2C and online supplemental file 5). Furthermore, pyroptotic tumors had decreased levels of cytokines and chemokines associated with protumor macrophages, and myeloid-derived suppressors cells (CCL2, CCL5, M-CSF) (figure 2C and online supplemental file 5). On the other hand, apoptotic tumors showed significantly higher levels of IL-9, IL-4 and CXCL2 and significant downregulation of IL-16, CCL5, IFN-b, LIF, IL-17, GMCSF (figure 2C and online supplemental file 6). Overall pyroptosis induces a profound immune-stimulating cytokine profile in vivo.

Pyroptosis preferentially activates type I cDCs
To evaluate the immune landscape after cell death, we established chimeric tumors by transplanting a mixture of parental MC-38 along with either MC-38-dd-Cterm-Cas8 or MC-38-NtermGas cells. Prior to establishing tumors, we confirmed that parental and NtermGas expressing cells have similar in vitro growth kinetics (online supplemental file 7), as a result, transplantation faithfully recapitulated chimeric tumors that activate apoptosis (online supplemental file 8) or pyroptosis after feeding of mice with Dox-medicated diet (online supplemental file 8).

To define the early processes influencing adaptive immunity after induction of cell death we quantified cDC within the tumor and draining lymph nodes (figure 3 and online supplemental file 9). Within the tumor, unlike apoptosis, pyroptosis preferentially induced a 24-hour time peak of cDC1 quantity with a higher phagocytic capacity as evidenced by uptake of ZsGreen expressed in tumors (figure 3A). Moreover, pyroptosis activated cDC1 had expressed SIINFEKL epitope in the context of MHC (figure 3A). Consistent with this, pyroptosis exposed tumors showed elevated cDC1 activation markers including CD40, CD80 and CD86 (figure 3B). Tumor draining lymph nodes showed a delayed but similar pattern of pyroptosis-specific increase in cDC1 quantity, phagocytic activity, antigen presentation and costimulatory molecule expression at the 48-hour time point (figure 3C,D). Both apoptosis and pyroptosis increased the total cDC2 count within the tumor, although pyroptosis had significantly higher number (figure 3E). Both types of cell death had intratumoral peak of cDC2 mediated phagocytic activity at the 24-hour time point (figure 3E). However, only pyroptosis exposed cDC2 showed elevated expression of SIINFEKL epitope (figure 3E). Both types of cell death stimulated CD40 expression in cDC2, although apoptosis induced CD80 and pyroptosis preferentially activated CD86 (figure 3F). In the tumor draining lymph node, apoptosis and pyroptosis exposed mice did not show significant difference in cDC2 quantity, phagocytic activity, antigen presentation and costimulatory molecules expression. However, both apoptosis and pyroptosis exposed mice had a higher cDC2 quantity and phagocytic activity (figure 3G,H).

Tumor-specific CD8+ T cells drive the antitumor response during pyroptosis
We next examined if the cDC1 response generated during pyroptosis translated into tumor specific CD8+ T cell response. For this, we established chimeric tumors expressing the LCMV glycoprotein gp33 epitope. Seven days after start of Dox-medicated diet, we quantified T cell responses in the blood or within the tumor. Pyroptosis generated higher number of tumor infiltrating CD8+ T cells compared with apoptosis that also showed a moderate T cell infiltrate compared with control tumors (figure 4A). Both apoptosis and pyroptosis showed equivalent increase in gp-33 specific CD8+ T cells in the circulation (figure 4B, online supplemental file 10); however, pyroptosis primed antigen experienced CD44+ CD8+ T cells displayed a higher activation pattern as defined by CD69 expression (figure 4C). Consistent with the proportion of activated T cells, pyroptosis primed cytotoxic T cells showed a higher killing capacity against cocultured gp33 expressing MC-38 cells (figure 4D). Restimulation of TILs with a cocktail of peptides (gp33, and MC-38 neoantigens, Adgpk, and Rpl18) followed by intracellular cytokine staining (ICS) revealed only pyroptosis exposed tumors had a higher IL-2+, TNF-α+ or concurrent IL-2+ and TNF-α+ CD8+ T cells suggestive of polyfunctionality (figure 4E–H, online supplemental file 11). Surprisingly, pyroptosis-induced antigen specific T cells did not secrete IFN-γ (figure 4G). Consistent with highly functional cytotoxic T cells, pyroptosis exposed tumors had a lower quantity of Treg within the tumor (figure 4I).

Pyroptosis extends survival of tumor-bearing mice in cDC1 and T cell-dependent manner
Given the higher magnitude of activated cDC1 and cytotoxic T cell response, we evaluated the antitumor benefits of pyroptosis in prophylactic and therapeutic settings. MC-38-NtermGas and MC-38-dd-CtermCas8 tumor-bearing mice were fed with Dox-medicated diet to eradicate primary tumors within 7 days (figure 5A). Rechallenge of pyroptosis and apoptosis exposed mice with parental MC-38 tumors on the contralateral flank conferred 40% and 85% long-term survival, respectively (figure 5B,C). All the naïve mice challenged with MC-38 tumor cells showed 100% tumor growth. Apoptosis, but not pyroptosis, exposed mice fully succumb to the second tumor rechallenge done at 100 days. In addition, 40% of the pyroptosis exposed mice remained refractory against subsequent rechallenges done at 200 days (figure 5C).
We next examined if the induction of pyroptosis results in therapeutic benefit. Induction of pyroptosis slowed the growth of chimeric tumors (figure 5D) and extended the median survival of mice (median survival of 29 days, 25% of the mice remained tumor-free) compared with apoptosis (median survival of 12 days, no tumor-free mice) (figure 5E). The treatment benefit was consistent in large chimeric MC-38 tumors where induction of pyroptosis displayed extension of median survival (online supplemental file 12, apoptosis having 12 days median survival vs pyroptosis conferring 20 days median survival). The anticancer effects of pyroptosis extends to a non-T cell inflamed KP1.9 tumor model since pyroptosis exposure prolonged the median survival of tumor-bearing mice (median survival of parental tumors—11 days, KP1.9+KP1.9-NtermGas chimeric tumor without Dox-medicated diet- 14 days, KP1.9+KP1.9-NtermGas chimeric tumor fed with Dox-medicated diet—19 days) (online supplemental file 13). Collectively, the findings suggest that in prophylactic and therapeutic settings pyroptosis provides better antitumor immunity than apoptosis.

To determine the antitumor contribution of cDC1, we assessed tumor growth and survival in wildtype versus Batf3−/− mice that lack cDC1. While pyroptosis protected 80% of the wildtype mice on tumor rechallenge, Batf3−/− mice lacking cDC1 were fully susceptible to tumor rechallenge (figure 6A) even after transfer of wildtype CD8+ T cells (figure 6B). Furthermore, the depletion of CD8+ T cells but not CD4+ (online supplemental file 14) completely ablated the antitumor immune response of pyroptosis rendering mice susceptible to the tumor rechallenge (figure 6C).
Supplemental material
In this study, we elucidated that synchronized and rapid cancer cell apoptosis and pyroptosis have remarkable differences in danger signal, cytokine, and chemokine emission as well as anticancer effect dependent on cDC1 and CD8 T+ cells.
Our findings that show pyroptosis stimulates anticancer immunity through the release of danger signals and proinflammatory cytokines is in line with results from previous reports.28 32 Consistent with the role of cDC1 in pyroptosis, we found higher level of chemokines CCL21 and CCL22 in pyroptotic tumor homogenates. It is tempting to speculate these chemokines to be associated with the cDC1-mediated anticancer immunity.38–40 A recent scRNA seq identified CCL22+ cDC1 population after CD40 agonist therapy in MC-38 tumors.41 In addition, CCL21 is a CCR7 ligand, and it is crucial for cDC1 trafficking into the draining lymph node. In our study, the contribution of cDC1 during pyroptosis-mediated antitumor immunity was best confirmed using Batf3−/− mice where loss of cDC1 completely ablated the antitumor response. Supporting this, pyroptosis exposed tumors and draining lymph nodes are endowed with a higher quantity of cDC1 displaying uptake of dying cancer cells, activation markers and presentation of the antigens in the context of MHC. Previous studies have elucidated that intratumorally injected necroptotic fibroblasts elicit cDC1 dependent antigen presentation and T cell activation.23 The types of cytokines and chemokines emitted during necroptosis23 and our tumor pyroptosis are remarkably different and it remains intriguing how distinct ICD-associated secretomes shape cDC1 heterogeneity and functionality. Hence, this model of pyroptosis can be exploited as a ligand-free system to understand numerous aspects of cDC1 biology including chemotaxis factors that facilitate cDC1 trafficking as well as transcriptome changes that dictate the role of cDC1 in antigen uptake and presentation.
Pyroptosis activated a high proportion of circulating and tumor infiltrating cytotoxic T cells (TILs). ICS analysis of TILs after restimulation with the neoantigen peptide cocktail showed secretion of IL-2 and TNF-α but not IFN-γ. In addition, pyroptosis primed cytotoxic T cells isolated from spleen of tumor-bearing mice had a higher proportion of rapidly reactivated antigen experienced CD44+CD69+ expressing T cells that exerted robust killing of cocultured tumor cells. Consistent with these qualities of pyroptosis primed T cells, we observed higher protection conferred to pyroptosis, unlike apoptosis, exposed mice at 100 days after the rechallenge. Future studies will investigate if the functionality of pyroptosis primed T cells is mediating the long-term protection against rechallenge. It also remains to be seen if pyroptosis primed T cells can infiltrate non-T cell inflamed tumors and function in highly suppressive tumor microenvironments. At the least, the finding of reduced Treg in pyroptosis exposed tumors is suggestive of its broader immunostimulatory effects in the tumor microenvironment.
Our findings highlight that pyroptosis provides superior systemic and long-lasting antitumor immunity compared with apoptosis. Hence, approaches to activate cancer cell pyroptosis via pharmacological or genetic methods can be translated into patients with cancer to reignite the anticancer immunity. In fact, some cancers evade immune attack by downregulating the pyroptosis effector gasdermin proteins. Hence, targeted delivery of gasdermin A3 provided potent anticancer effect.42 In addition, engineered OVs have successfully delivered cell death payloads such as MLKL to induce necroptosis.43 Lastly, engineered OVs expressing gasdermin or those OVs naturally activating pyroptosis27 should be rigorously evaluated in humanized mouse settings to evaluate their anticancer effect against patient derived xenografts.
Cell culture
Murine colon adenocarcinoma (MC-38) was maintained in Dulbecco's Modified Eagle's media supplemented with 10% fetal bovine serum (FBS) and 100 U/mL of penicillin/streptomycin (P/S). KP 1.9 is a cloned lung adenocarcinoma cell line that arose spontaneously in a K-rasLA1/p53R172HΔg mouse model. KP 1.9 cells were a generous gift from Prof. Alfred Zippelius (University Hospital Basel, Switzerland), who originally developed the cell line. KP 1.9 cells were maintained in Iscove Modified Dulbecco media with 10% FBS and 100 U/mL P/S.
Generation of stable N terminus gasdermin E and caspase 8 expressing cell lines
N-terminal gasdermin E (NtermGas) and dimerizable (dd) C-terminal Caspase 8 (dd-CtermCas8) DNA sequences were cloned into the piggyBac (pB) vector (pB-TET) downstream of a Dox inducible TRE-tight promoter as previously described.44 MC-38-gp33 and KP-1.9 were transfected using a lipofectamine 3000 (Invitrogen) and the three vector constructs PB-TET-NtermGas or PB-TET-dd-CtermCas8 (response plasmid with cell death protein of interest), PB-CAG-rtTA-Neo (expresses regulatory protein, rtTA), and pCyL43 (plasmid that encodes for transposase) in a ratio of 10:5:2, respectively. Transfected cells were selected using neomycin and clones were screened for inducible expression of procell death proteins. Cell death activating MC-38 cell lines were used to express ZsGreen-SIINFEKL, a fusion protein of the fluorescent protein ZsGreen and SIINFEKL epitope. The expression of ZsGreen-SIINFEKL was normalized between MC-38-dd-CtermCas8 and MC-38-NtermGas cell lines by selection of subclones with equivalent geometric mean fluorescent intensities (online supplemental file 15).

Animal experiments
Female C57/Bl6 mice aged 6–8 weeks old (Charles Rivers Laboratories) were subcutaneously implanted with 2 million tumor cells as described previously.13–15 For therapeutic settings, chimeric tumors were established by injecting 1×106 parental MC-38-gp33 or KP-1.9 cells together with 1×106 MC-38-gp33 or KP-1.9 cells with an inducible cell death cassette. 12–14 days after implantation, tumors achieved a treatable tumor volume (80–150 mm3). Prior to start of treatment mice were randomized among groups to ensure an equal tumor volume across treatments and controls. For all studies requiring inducible expression of procell death proteins mice were fed 625 mg/kg Dox-medicated diet (Envigo Teklad, Madison USA). In prophylactic experiments, mice were rechallenged with 2×106 MC-38-gp33 cells injected subcutaneously on the contralateral flank after eradication of the primary tumor. Batf3−/− mice were purchased from The Jackson Laboratory. For T cell depletion studies, mice were injected intraperitoneally on day 0, 3, and 7 with either isotype or 250 mg anti-CD4 (clone GK1.5, BioXcell) and anti-CD8 (Clone 2.43, BioXcell). For all experiment groups, tumors were measured every 3–4 days with tumor volumes of 1000 mm3 classified as endpoint.
Quantification of cell viability
Intracellular ATP was measured using the CellTiter-Glo kit (Promega) as a surrogate marker for cell viability. At stated time point, cells were lysed then following the manufacturer's instructions and luminescence reading measured using the Enspire multimode plate reader (PerkinElmer).
In vitro quantification of extracellular HMGB1, ATP, cytokines, and chemokines
Cell-free supernatant from dying and control cells were harvested after centrifugation of the media at 2000 rpm for 10 min. All samples were immediately frozen at −80°C. Extracellular HMGB1 was quantified using an ELISA kit developed by Shino Test (IBL International). The ELISA was conducted according to the manufacturer's instructions. For extracellular ATP analysis, supernatants were analyzed using an ENLITEN ATP assay kit (Promega) according to manufacturer's instructions. Cell-free supernatants were shipped to Eve Technologies for 44-Plex murine cytokine/chemokine analysis.
Quantification of surface calreticulin expression
Expression of surface calreticulin after apoptosis or pyroptosis was quantified using flow cytometry. Briefly, cells were seeded at a density of 150,000 cells/well in a 6-well plate and allowed to adhere for 16 hours before treatment with Dox for stated time points. Cells were then collected and washed with PBS before staining with Fixable Viability Stain 510 and anti-calreticulin-PE (EPR3924, 1:5000). Data were acquired on BD FACS Canto II and analyzed in FlowJo.
Quantification of cytokines, chemokines, and cell death proteins in tumor homogenates
Tumors were resected from mice and diced into small pieces before being homogenized in tissue extraction solution (50 mM Tris, pH 7.4, 250 mM NaCl, 5 mM EDTA, 2 mM Na3VO4, 1 mM NaF, 20 mM Na4P2O7, 1 mM b-glycerophosphate, 1% NP-40). Tumors were incubated for 30 min on ice and debris was clarified by three sequential steps of centrifugation at 14,000×rpm for 10 min at 4°C. Tumor homogenates with equal concentration of protein were shipped to Eve Technologies (Calgary, Canada) for 44-Plex murine cytokine/chemokine analysis.
Isolation of immune cells
Tumors were resected and weighed before being placed into RPMI containing Liberase TL Research Grade (250 µg/mL; Roche) and DNase I (1 mg/mL; Sigma-Aldrich). Tumors were minced with scissors and incubated at 37°C for 35 min for enzymatic digestion. Tumor pieces were subsequently crushed against a 70 µm filter to generate a single cell suspension. Cells were washed with PBS containing 2% FBS and 1 mM EDTA. Leucocytes were isolated from each respective single cell suspension using a EasySep Release Mouse Biotin Positive Selection Kit (Stem Cell Technologies) in conjunction with an anti-CD45.2-Biotin (Clone 104) according to the manufacturer's guidelines. Tumor draining lymph nodes were harvested and pressed against a 70 µm filter and rinsed with Hanks Balanced Salt Solution. Blood was collected from the retro-orbital sinus and red blood cells were lysed using ACK buffer (150 mM NH4Cl, 10 mM KHCO3, and 0.1 mM Na2EDTA, pH 7.3).
Surface and intracellular staining of immune cells
Leucocytes were incubated with Fc block (anti-CD16/anti-CD32) and stained with fluorescently labeled antibodies and Fixable Viability Stain 510 (BD Biosciences). The following antibodies were obtained from BD Biosciences: anti-CD11c-APC-Cy7 (HL3, 1:200), anti-Ly6C-RB545 (AL-21, 1:100), anti-CD40-BV711 (3/23, 1:100), anti-CD80-BV650 (16–10 A1,1:100), anti-CD86-PE-CF594 (GL1, 1:100), anti-I-Ab-PE (AF6-120, 1:100), anti-CD103-PE-Cy7 (M290, 1:100), anti-CD64-BV786 (X54-5/71, 1:100), anti-CD3-FITC (17A2,1:200), anti-CD8-APC-Cy7 (53–6.7, 1:100), anti-CD44-PE (SB/199, 1:100), anti-CD69-APC (H1.2F3, 1:100), anti-CD4-APC-Cy7 (RM4-5, 1:200), anti-IFN-γ-APC (XMG1.2, 1:100), anti-IL-2-PE (JES6-5H4, 1:100), and anti-TNF-α-BV421 (MP6-XT22, 1:100). The following antibodies were from eBioscience: anti-FOXP3-PE (FJK-16s, 1:100), anti-CD11b-Pacific Blue (M1/70, 1:100), and OVA257-264 (SIINFEKL) peptide bound to H-2Kb Monoclonal Antibody (eBio25-D1.16 (25-D1.16))- PE. Anti-XCR1-BV421 (ZET, 1:100) was purchased from Biolegend. For ICS analysis, leucocytes were stimulated with gp33 (KAVYNFATM), Rpl18 (KILTFDRL), and Adgpk (ASMTNMELM) peptides (Biomer Technologies) (1 µg/mL per peptide) for 4 hours at 37°C. GolgiPlug (BD Biosciences) was added for the last 3 hours of incubation. Cells were stained as above in addition fixation and permeabilization using Cytofix/Cytoperm solution (BD Biosciences). To obtain absolute counts of cells, CountBright Absolute Counting Beads (ThermoFisher Scientific) were added to samples following manufacturer's instructions. Other reagents included the Tetramer H-2D(b)-LCMV-gp33-41-PE from the National Institutes of Health Core facility. Data were acquired on a BD FACSCanto II and a Cytek Northern Lights with downstream analysis completed using FlowJo software.
In vitro cytotoxicity assay
MC-38-gp33 cells were labeled with 3 µM carboxyfluorescein succinimidyl ester (CFSE; BD Biosciences) and seeded in a 96-well plate at 10,000 cells per well and cocultured with CD8+ T cells from the spleen for 10 hours. CD8+ T cells were stained with fixable viability stain 510 (BD Biosciences) and evaluated by flow cytometry. Per cent specific lysis was defined previously as: % specific lysis=100×(%specific cell death−% basal cell death)/100−%basal cell death, where basal cell death is the viability of MC-38-gp33 cells without T cells and specific lysis is the viability of CSFE positive MC-38-gp33 cells.45
Cells were lysed using radioimmunoprecipitation buffer (10 mM phosphate, 137 mM NaCl, 1% NP-40m 0.5% sodium deoxycholate and 0.1% sodium dodecyl sulfate) supplemented with phosphatase inhibitor cocktail (1.2 mM AEBSF, 13.6 µM bestatin 12.3 µM E-64 112 µM leupeptin1.16 µM pepstatin) and protease inhibitor cocktail (Millipore Sigma, Massachusetts, USA). For measuring HMGB1 cell-free supernatants were used. Total protein extracted from cells or tumor homogenates and cell-free supernatants were resolved using 7.5%–15% sodium dodecyl sulfate polyacrylamide gel electrophoresis and transferred to nitrocellulose membranes. Membranes were blocked in InterceptR (TBS) Blocking Buffer (Li-Cor Biosciences) followed by incubation with primary antibodies. The following antibodies were purchased from Cell Signalling Technologies: anti-Gasdermin E (Cat#40618, 1:3000), anti-β-actin (Cat#4967, 1:6000), and anti-Cleaved-Caspase-3 (Cat#9661, 1:3000). The following antibodies were purchased from Abcam: anti-Caspase-8 (Cat#ab25901, 1:3000). Membranes were then probed with secondary antibody conjugated to an infrared dye (IRDye 800CW Donkey anti-Rabbit IgG, 1:6000) and analyzed using an Odyssey DLx scanner (Li-Cor Biosciences).
Treated and control tumors were excised from euthanized mice and fixed in 10% formalin for 48 hours and then transferred to 70% ethanol before being embedded into paraffin blocks. Five µm thick tumor sections were deparaffinized prior to incubation in citrate buffer at 95°C for 15 min. Tumor sections were blocked with InterceptR (TBS) Blocking buffer (Li-Cor Biosciences) before addition of primary antibody. Anti-Gasdermin E (Cell Signalling Technologies, 40618) was diluted in Intercept Blocking Buffer with 0.2% Tween-20 and used at a working dilution of 1:500. Primary antibody was incubated overnight in a humidified chamber at 4°C in the dark. Signal amplification was completed using an anti-rabbit secondary antibody conjugated to Alexa-488 (Abcam, ab150077, 1:10,000). Secondary antibody incubation was performed at room temperature in a humidified chamber in the dark for 2 hours. Sections were counterstained with diluted DAPI (Abcam) for 5 min at room temperature in the dark. Slides were rinsed with MiliQ water before imaging with the Leica DMLB fluorescent.
Statistics and reproducibility
For each statistical test used, normality of the distribution and equality of variance between groups was evaluated beforehand. For differences in means, one-way analysis of variance (ANOVA), two-way ANOVA, Student's two-tailed unpaired t-test, and non-parametric Kruskal-Wallis test were used. The Holm Šidák method was used to correct multiple comparisons. For analyzing differences between experimental groups in Kaplan-Meier survival, the log-rank (Mantel-Cox) test was used with 525 mm3 as endpoints. Bar graphs are shown as mean±SD. The null hypothesis was rejected for p<0.05. All statistical tests and analyses were carried out using GraphPad Prism V.9.

To achieve professional vocals with effects processors, it is important to first start with a high-quality microphone that captures the nuances of your voice accurately. Once you have a solid recording, you can use effects processors such as reverb, delay, compression, and equalization to enhance your vocals.
Reverb can add depth and space to your vocals, making them sound fuller and more atmospheric. Delay can create a sense of movement and dynamics in your vocals, adding interest and excitement. Compression can even out the levels of your vocals, making them sound more polished and professional. Equalization can help you sculpt the frequency response of your vocals, getting rid of any unwanted frequencies and enhancing the clarity and presence of your voice.
When using effects processors, it is important to use them in moderation and to always keep the focus on enhancing your vocals rather than covering them up. Experiment with different settings and combinations of effects to find the perfect sound for your vocals. And always trust your ears – if something doesn't sound right, make adjustments until you achieve the professional sound you are looking for.
What is a doubler and how can it create depth in vocals with an Effects Processor?
A doubler is an effect used in audio production to create the illusion of multiple voices or instruments playing or singing simultaneously. It achieves this by duplicating the original voice or instrument, slightly altering the pitch, timing, and/or amplitude of the duplicate, and blending it with the original sound.
When using a doubler with an effects processor on vocals, it can create depth in the vocals by adding a sense of space and dimension to the sound. By slightly detuning the duplicated voice and adjusting the timing and volume of the duplicates, the vocals appear fuller and more dynamic. This can create a rich, immersive sound that adds depth and texture to the overall mix. Additionally, the effect can help thicken up the vocals and make them stand out in the mix.
Overall, doubling vocals with an effects processor can help enhance the overall sound of a vocal performance and make it more engaging for listeners.
How to set up a noise gate on an Effects Processor to eliminate unwanted noise in vocals?
Setting up a noise gate on an effects processor is a simple process that can greatly improve the quality of your vocal recordings. Here are the steps to properly set up a noise gate:
- Connect your microphone to the effects processor using an XLR cable.
- Turn on the effects processor and select the channel that your microphone is connected to.
- Locate the noise gate function on the effects processor. This can usually be found in the dynamics or gate section of the processor's settings.
- Set the threshold level of the noise gate. This is the level at which the gate will engage to eliminate unwanted noise. Start by setting the threshold to a low level, and gradually increase it until the noise is no longer present during silent moments.
- Adjust the attack and release settings of the noise gate. The attack setting determines how quickly the gate engages once the threshold level is reached, while the release setting determines how quickly the gate disengages once the input level drops below the threshold. Fine-tune these settings to ensure the gate is smooth and natural sounding.
- Test the noise gate by speaking or singing into the microphone. Make sure that the gate is effectively eliminating unwanted noise without cutting off the beginning or end of your vocal passages.
- Save your settings on the effects processor for future use.
By following these steps, you can effectively set up a noise gate on an effects processor to eliminate unwanted noise in vocals and improve the overall quality of your recordings.
How to configure a multi-effects unit to achieve a desired vocal sound with Effects Processors?
To achieve a desired vocal sound with effects processors, follow these steps:
- Choose the right effects unit: Make sure the multi-effects unit you are using has the specific effects you need for your desired vocal sound. Some common effects for vocals include reverb, delay, compression, and pitch correction.
- Connect your microphone to the effects unit: Use an XLR cable to connect your microphone to the input of the effects unit. Make sure the input level is set correctly to avoid clipping.
- Choose the effects: Experiment with different effects to see how they affect your vocal sound. Start with basic effects like reverb and delay, and then add more effects as needed.
- Adjust the parameters: Each effect will have different parameters that can be adjusted to customize the sound. Experiment with parameters like decay time, feedback, and mix levels to achieve the desired effect.
- Save your settings: Once you have found a combination of effects that works well for your vocal sound, save the settings on the effects unit so you can recall them easily in future performances.
- Fine-tune the sound: Listen carefully to your vocal sound and make any necessary adjustments to the effects settings to achieve the desired sound. Pay attention to things like balance, clarity, and dynamics.
- Practice and experiment: The key to getting the perfect vocal sound with effects processors is to practice and experiment with different settings. Try different effects combinations and settings to see what works best for your voice and style.
By following these steps and experimenting with different effects and settings, you can achieve a desired vocal sound with effects processors.
What is the difference between chorus and flanger effects on an Effects Processor for vocals?
Chorus and flanger effects both modulate the original signal to create a swirling, moving sound, but they achieve this in slightly different ways.
Chorus effects add a delayed and pitch-modulated version of the original signal to create a thicker, richer sound with a sense of movement and depth. This creates the illusion of multiple voices singing or playing together in harmony.
Flanger effects, on the other hand, use a time-delayed signal that is constantly changing in frequency to create a jet-like sound. This produces a more pronounced and swirling effect with a metallic edge.
In summary, chorus effects create a more subtle and harmonious sound, while flanger effects produce a more pronounced and metallic-like sound with sharper movement. Ultimately, the choice between using chorus or flanger effects for vocals will depend on the desired sound and artistic vision for the music. |

The Nan ED Project – Electron Nanocrystallography, is an Innovative Training Network, Marie Skłodowska-Curie Actions, project funded by EU (grant agreement n. 956099) aimed to train a new generation of electron crystallographers thereby paving the way for future development and establishment of the method more broadly in the academic community and within the industry.
Electron crystallography is a way of looking into the structure of matter exploiting electron scattering in a transmission electron microscope. Its main strength relies on the strong character of electron matter interaction, which allows detectable diffraction signals on crystal having size of few nanometers. Collecting this signal in 3D and determining the atomic positions in nanocrystals of any kind, minerals, inorganic, hybrid, organic, pharmaceutical and macromolecular is the final goal of NanED.
Codex International will be involved throughout the project, contributing its expertise to help meet the program's technological challenges.
DécouvrirResearchers from the University of Rostock and Technion Haifa have created the first three-dimensional topological insulator for light. A judiciously placed screw dislocation allows optical signals to wind around the surface of a synthetic lattice while keeping it protected from scattering.
Their discovery has recently been published in the journal Nature (« Photonic topological insulator induced by a dislocation in three dimensions »).
In many respects, the human brain is still superior to modern computers. Although most people can't do math as fast as a computer, we can effortlessly process complex sensory information and learn from experiences, while a computer cannot – at least not yet. And, the brain does all this by consuming less than half as much energy as a laptop.

In the quest for energy independence and sustainability, more homeowners are turning to solar power as a viable solution. Solar panels offer a clean, renewable source of energy that can significantly reduce electricity bills and decrease reliance on fossil fuels. However, with the multitude of options available in the market, choosing the right solar panels for home can be a daunting task. Fear not, for in this comprehensive guide, we will walk you through everything you need to know to make an informed decision.
Understanding Solar Panels
Before delving into the selection process, it's essential to have a basic understanding of how solar panels work. Solar panels, also known as photovoltaic (PV) panels, harness sunlight and convert it into electricity through the photovoltaic effect. Each panel is made up of solar cells, typically composed of silicon, which generate direct current (DC) electricity when exposed to sunlight. An inverter then converts this DC electricity into alternating current (AC), which can power your home's electrical appliances.
Factors to Consider
When choosing solar panels for home, several key factors should influence your decision:
Energy Needs: Begin by assessing your household's energy consumption. Consider factors such as the size of your home, the number of occupants, and your typical electricity usage patterns. This evaluation will help determine the size and capacity of the solar panel system required to meet your needs.
Roof Space and Orientation: The amount of available roof space and its orientation relative to the sun are crucial considerations. Ideally, your roof should have sufficient unobstructed space to accommodate the solar panels and receive adequate sunlight throughout the day. South-facing roofs typically receive the most sunlight in the northern hemisphere, maximizing energy production.
Panel Efficiency: Solar panel efficiency refers to the amount of sunlight converted into electricity. Higher efficiency panels can generate more power in limited space, making them ideal for homes with limited roof space. While more efficient panels may come at a higher initial cost, they can offer greater long-term savings by maximizing energy production.
Quality and Durability: Investing in high-quality solar panels is essential to ensure reliable performance and longevity. Look for panels from reputable manufacturers with a proven track record of reliability and durability. Consider factors such as warranty coverage, product certifications, and customer reviews to assess the quality of the panels.
Cost and Financing Options: Cost is a significant consideration for most homeowners when purchasing solar panels. While upfront costs may seem daunting, it's essential to consider the long-term savings on electricity bills and potential incentives or rebates available for solar installations. Explore financing options such as solar loans, leases, or power purchase agreements (PPAs) to make solar more affordable.
Types of Solar Panels
Solar panels come in various types, each with its advantages and considerations:
Monocrystalline Solar Panels: Made from single-crystal silicon, monocrystalline panels are known for their high efficiency and sleek appearance. They perform well in low-light conditions and have a longer lifespan compared to other panel types.
Polycrystalline Solar Panels: Polycrystalline panels are made from multiple silicon crystals and are slightly less efficient than monocrystalline panels. However, they are more cost-effective and offer good performance in sunny climates.
Thin-Film Solar Panels: Thin-film panels are lightweight and flexible, making them suitable for unconventional installation surfaces such as curved roofs or building-integrated applications. While they tend to have lower efficiency, thin-film panels can be a practical solution for specific solar projects.
Choosing the Right Solar Provider
Once you've determined your solar panel requirements, selecting the right solar provider is crucial to ensure a successful installation and optimal performance. Here are some tips for choosing a reputable solar provider:
Experience and Expertise: Look for a solar provider with extensive experience in the industry and a proven track record of successful installations. Experienced providers are more likely to offer quality products and reliable service.
Customer Reviews and References: Research customer reviews and ask for references from past customers to gauge the provider's reputation and customer satisfaction levels. Positive reviews and testimonials are indicative of a trustworthy provider.
Licensing and Certification: Ensure that the solar provider is properly licensed and certified to install solar panels in your area. Licensing and certification demonstrate compliance with industry standards and regulations, as well as a commitment to quality and professionalism.
Warranty and Support: Inquire about the warranty coverage and after-sales support offered by the solar provider. A reputable provider should offer comprehensive warranty coverage for both the solar panels and the installation work, as well as ongoing support for maintenance and troubleshooting.

Do you know the feeling when you're excited because you're about to read a long-awaited book? Or when you're on your way to see a movie you like? When I was little, I remember being the kind of kid who could spend hours reading until the middle of the night to see what would happen in the story. That's how powerful a story can be!
Believe it or not, researchers have found a scientific explanation for this pleasant feeling. Listening to or reading a good story can make you release oxytocin, a hormone related to empathy and love. So, you may ask, what does a story have to do with narrative? Are they the same?
First, the narrative is the term we use to define events happening in a story, usually told by a narrator. In this, different characters make the decisions and actions that cause the events. In simpler words, the story needs the narrative.
Even though the narrator can describe the events in the narrative with written or spoken words, the use of both of those has changed over the years. In medieval times, oral storytelling was the most common way to express a narrative, and people from different cultures used stories to teach values and history. Similarly, people used storytelling as a way to socialize. The main characteristic of oral storytelling is the physical proximity of the narrator to the listeners, and teachers also recognize this type of storytelling as an easy way to introduce literature in childhood. However, with the introduction of devices that allow communication such as radio, television, or computers, these practices are less common than before. Today, we use electronic devices that make it easier to communicate from far distances but also diminish face-to-face communication and oral storytelling.
The way of storytelling has changed significantly. We see stories everywhere. Even if, at first, it doesn't seem like it, narratives are present not only in books, movies, or TV but also in songs, video games, or paintings. Consequently, if you want your story to work, it needs a structure, and today that's what I'll tell you about in this article.
What is the narrative?
It expresses the events in a story according to the eyes of a narrator. Some people use it as a synonym for story.
What are narrative structures?
It's how the narrator tells those events to the reader. In addition, it includes the manner and the order to do it and involves two main definitions: plot and setting.
What is the plot?
On the one hand, the plot it's one of the elements present in a story, and sometimes people use it as a synonym for the narrative. However, the plot as a device focuses more on the order of the events that create the story.
What is the setting?
On the other hand, the setting is where the narrative (and, therefore, the plot) takes place. Along with the plot and characters, it's one of the elements you must understand if you want to write a story.
What are the types of narratives?
If the narrative is how the narrator tells events that happened, the type of narrative is the way it explains them. The most common ones in books include linear narrative and nonlinear narrative.
Linear narrative
Probably the most used in books, it's where the narrator tells us everything that happens in the order it happened. In this type of narrative, one thing leads to another seamlessly, and it's easy for the reader to follow since figuring out how the events occur is not one of the readers' concerns.
There are lots of books with this narrative. A famous example includes Pride and Prejudice by Jane Austen, where we can see the main character's development, Elizabeth, and her relationship with Mr. Darcy.
Romantic stories benefit from this type of narrative, but it also works with fantasy, science fiction, and young adult. If you want to tell and don't want to stress yourself (and your reader), write a linear narrative!
One of the weaknesses of this type of narrative is that you cannot show events that happened in the past, only if a character in your story describes it, and sometimes this can be boresome.
Nonlinear narrative
On the contrary, a nonlinear narrative will not tell us the events as they happened. Instead, we will learn the events in the order the narrator wants to describe them. Making this work is tricky since you count on the ability of the reader to discover by themselves how things happened, and it's challenging to do it right. However, if you do it right, it will be memorable. It's a type of narrative that gives the story more depth and works wonders in thrillers and mysteries.
One example is Gone Girl by Gillian Flynn. In Gone Girl, Nick Dunne is the main suspect in his wife's disappearance, Amy. While part of the book is in the present, a section with Amy's diary tells us about events that happened years ago. In this case, Amy's diary helps the reader understand what could've happened between her and his husband. Most important, it helps us know if Nick genuinely killed her wife.
The main disadvantage of this type of narrative is that you can confuse your reader, and a confused reader is a reader who may stop reading your book. You can ask someone who doesn't know the plot of your book to read it for the first time and ask about their opinion: do you understand the chronological order, or is it too complicated?
Are there other types of narrative?
Way more common in video games, there is also interactive storytelling. It's the kind of narrative where you learn clues that lead you to another one, advancing the plot. One famous example includes Detroit Become Human, a video game where you explore a fictional Detroit in 2038 through the eyes of three different androids. Depending on your choices, your character may have different results, including death. It is different from linear and nonlinear narratives in that there is no single outcome, and each event after the other will depend on the decisions made by the user.
What are the narrative structures?
Narrative structures seek to explain how events occur under a specific pattern of steps or acts, which, although they change according to the plot of each book, usually occur in the same order. For that same reason, they are crucial in storytelling. We need them to organize and present information to the reader, and depending on which one you use, you can use them to create suspense and keep your readers hooked.
There are different narrative structures, and I will explain the three most common ones: The Hero's Journey, the Three Act Structures, and Dan Harmon's Story Cycle. To make it easier to understand, I will explain it with the plot of Harry Potter and the Sorcerer's Stone.
The Hero's Journey
Without realizing it, you may have heard of this one. The Hero's Journey is the most famous narrative structure in movies and books, and you don't have to be an expert storyteller to realize why: we all love to see a hero winning! It uses the concept of the monomyth, a term that anthropologist Joseph Campell used to describe different epic tales along different cultures in the world. This anthropologist was not only the creator of the concept but also wrote a work where he exemplifies this narrative structure named The Hero With a Thousand Faces. Still, some say the popularity of this story structure is thanks to George Lucas, director of the Star Wars series.
What's the Hero's Journey Structure?
Today, the most famous version of The Hero's Journey is the version popularized by Christopher Vogler, consisting of 12 steps.
- The Ordinary World. First, we see how the main character lives their ordinary lives. For example, Harry Potter lives with his family in England, who bully him and make him feel powerless.
- The Call of Adventure. Also called the inciting incident, in this case, Harry Potter learns he's a wizard, and from here, the plot begins to unfold.
- Refusal of the Call. The hero doesn't want to accept the call. Harry thinks there must be a mistake; there's no way he's a wizard.
- Meeting the Mentor. The hero encounters someone who will teach them how everything works in the magical world. In Harry Potter's first book, this mentor is Hagrid.
- Crossing the Threshold. Also known as stepping out of the comfort zone. In this step, Harry goes to Hogwarts.
- Tests, Allies, Enemies. Harry meets Ron and Draco, a friend and an enemy, respectively. Harry is also struggling to keep up with his school lessons.
- Approach to the Inmost Cave. Our hero almost gets what he wants. In this step, Harry Potter learns he can be good at Quidditch and get recognition for it. He will no longer feel powerless.
- The Ordeal. Our hero was having a good time in his new environment and getting used to it until The Ordeal arrived. We see the biggest challenge for our hero: a troll threatens Hermione's life. Harry and Ron save her.
- Reward (Seizing the Sword). Thankful to them, Hermione becomes their friend. She's smart, and she would become one of their best friends.
- The Road Back. Even if this isn't present in Harry Potter, it would be the moment when the hero realizes that overcoming the challenge in The Ordeal wasn't the end. Things might get worse.
- Resurrection. Also called climax, here is where the final challenge happens. For the first time, we see Voldemort as he tries to kill Harry.
- Return with the Elixir. The hero gets what he wants! Harry escapes from Voldemort, and people recognize Harry as a hero. Harry returns to his family.
The Hero's Journey has helped different authors across different media, who use it mostly in fantasy or science fiction.
Three-Act Structure
Have you heard that classic phrase that goes, every story has a beginning, a middle, and an end? Well, they were probably referring to the three-act structure. It's similar to The Hero's Journey but way more simplified.
What's the Three-Act Structure?
Act 1. Setup
We meet Harry Potter, an orphan who lives in England with his closest relatives. However, they bully him, and on top of that, Harry doesn't have any friends. Still, Harry's life changes when he learns he can make magic and will study at Hogwarts School of Witchcraft and Wizardry.
Act 2. Confrontation
When Harry starts attending Hogwarts, he makes friends and enemies. But most importantly, he learns about Voldemort, the most dangerous threat in the magical world.
Act 3. Resolution
In the final act, Harry fights Voldemort and manages to escape. All along the way, Harry has changed. He is now a wizard with friends who love him.
Dan Harmon's Story Cycle
This one is one of my favorites! Created by Dan Harmon, co-creator of Rick And Morty, it's a variation of the monomyth structure. However, the main difference is that the Story Cycle focuses more on the main character and their needs to move the plot forward. The Story Cycle wants the main character to have character development, giving them different arcs as the story progresses.
Harmon explains the narrative of his characters with the philosophy that human beings love stories that follow a cycle. The phrase to describe this narrative goes like this: when you have a need, you go somewhere, search for it, find it, take it, then return, and change things.
What's Dan Harmon's Story Cycle?
- You. Here, we learn how the main character is in their comfort zone. For example, Harry lives in England without friends, and his family bullies him.
- Need. The main character needs something. It could be something the character has wanted for a long time, but it could also be something recent after a specific incident. For example, Harry wants friends, and after he learns he is part of the magical world, the story allows him to change his situation.
- Go. To change, the protagonist has to get out of his comfort zone. In this step, the character goes into an unfamiliar situation. Harry Potter goes to Hogwarts.
- Search. The protagonist adapts to the new world they entered and begins their search. In this case, Harry started a new life in this new school.
- Find. The protagonist wins a small victory by getting what he wants, but why doesn't it feel like a victory? We call this a false win. Harry's success, in this case, is learning he can be good at Quidditch, but getting deeper and deeper into the magical world has consequences. The protagonist needs to pay for it.
- Take. It can be a moment to reflect that maybe what the character wanted wasn't worth it. Harry now has friends and popularity, but it doesn't stop there. Entering the magical world brings him closer and closer to his villain and main threat: Voldemort. The character doesn't have other options, so they pay the price. In Harry's case, he has to fight Voldemort.
- Return. After escaping Voldemort, we go back to the familiar situation. Harry goes back to his home.
- Change. The protagonist has changed. We see their character development, and whether it was for better or worse depends on the other seven steps and the final you want to achieve. Harry now believes in himself and his abilities. He has friends, and he is loved.
Narrative structures exist because they work, but today, nothing says you have to follow one of those to make a good book. On the contrary, your book may be following a narrative structure without you realizing it.
However, you can search for narrative structures when you think your writing is bland or the reader doesn't feel as immersed in the story as they should be. If you are not convinced, you can always practice! You may find one that suits you and your writing style.
Finally, these structures can help you if you're a beginner, but you could also use them if you consider yourself a writing expert.
Remember, the best way to practice writing is by writing, of course, but also by reading, so have a good read!

"A problem well stated is a problem half solved." – John Dewey
Growth, diversification, expansion, and modernization represent key themes that define the nature of contemporary organizations. These themes, when viewed through analysts' magnification lenses, present images that display a constant ongoing dynamic animated by adverse factors, challenges, problems, fluctuations, disruptions, and negation, among others. Therefore, it is incumbent on companies, conglomerates, organizations, and businesses to ideate, develop, create, implement, and refine problem solving processes that address said elements and allow the organizational dynamic to gain – and sustain – positive momentum.
Such processes must gain form and structure inside flowcharts since this stance allows organizations to conduct extensive analyses of problems, discover their origins, survey their effects, consider a range of alternatives, explore outlines of potential remedies, design prototypical solutions, and implement corrections and refinements at specific locations. In addition, flowchart-based illustrations allow organizational forces to analyze the nature of problems and disruptions, allowing the formulation of multi-tiered solutions that animate and implement the essence of problem solving processes.
Acts of ideation and detailed execution remain at the core of effective problem solving processes. In light of this assertion, designers of flowcharts could outline spaces and panels inside illustrations with a view to accommodate new ideas, revisionary stances, process interventions, additions, and instances of modulation. Such an illustration could take shape as sets of stages; each visually affiliated with panels and spaces. Such configurations allow experts and specialists to review the operation and execution of processes, locate instances of disruption and dissonance, and fashion long-term solutions as part of implementing corrections. The use of colors and tints remains instrumental in these undertakings; these elements can visually delineate the outlines of interventions and solutions, thus projecting a clear image of smooth operations and rapid execution of designed processes.
Quantifying the efficiency of segments inside (industrial, technological, and commercial) processes against a defined baseline serves as a precursor to the success of problem solving processes. Pursuant to this, process operators could draw on their experience to create a baseline, survey the actual operations of systems and processes, and calculate efficiency quotients registered by segments, stages, and sub-stages of processes under review. This technique allows operators to evaluate core efficiency levels, conduct benchmarking studies, and assess deficits (if any) in extant segments of processes. Such an illustration hinges on access to digital technology, whereby sets of operational data helps actuate such interventions. In addition, instances of successful intervention could undergo codification into models that find application across any industry or commercial domain. In effect, the insights gained from flowchart-based interventions could help define new methodology that validate and expand established troubleshooting practices.
Smart, insightful analyses of root causes forms a core component of problem solving processes designed and integrated inside the modern flowchart. Such analyses must gain impetus from a fact-based survey that seeks to uncover root causes of manifest problems inside processes. Proven methodology such as Six-Sigma and Fishbone diagrams can aid such an initiative; in addition, designers and analysts must work to trace the outlines of root causes, unearth any convergences, locate sequences of dissonance, and invest in extensive analyses. Flowcharts can assist in the visual narration of such activity; illustrate the outcomes of analyses, present findings to readers and reviewers – thus driving effective implementation of problem solving processes. Additionally – these diagrams could help cement the key impulses that provide impetus to said processes, thereby contributing to the body of expertise, experience, and knowledge in this domain.
Collaboration between departments of an organization (and consultants and external specialists) could help attain milestones in the execution of problem solving processes. Pursuant to this, business operators could design specific modules inside flowcharts to promote acts of co-execution and collaboration. This stance allows a pooling of expertise, insights, awareness, and knowledge, thereby defeating dangers posed by silo-based operations of processes. The spaces of collaboration could manifest a specific geometry, one defined by timelines, observation of outcomes, experimentation and exploration, and assessments of process results. These spaces could include mechanisms that can anticipate problems inside processes based on evaluation of operating metrics. Further, the scope of collaboration could widen to include greater resonance with the overarching objectives of an organization; such objectives could include the design of larger production processes, higher volumes of output, greater levels of process complexity, and complete overhauls undertaken in response to stimuli generated in the external environment.
Intelligently designed problem solving processes may output multiple solutions that could undergo assessments at different levels. When designed inside flowcharts, this technique enables creators to explore various levels of troubleshooting in different aspects of relevant context. For instance, operators of commercial logistics services could design flowcharts to reach optimal solutions that balance, inter alia, costs of fuel consumption, route mapping for delivery vehicles, expansion of operations into new territories, hiring new employees, the use of business analytics, catering to customers' demands, and driving innovation in marketing strategies. The visual shape of the resulting flowchart offers movement in every direction resulting from an expansive exploration and delineation of problem solving processes. Inter-connections could emerge as a defining motif in such diagrams, thereby creating visually dense representations of troubleshooting initiatives.
Operators of outsourcing businesses could elect to etch creative strategies as part of constructing problem solving processes inside flowcharts. These strategies could variously relate to management of human talent, technology-driven platforms, client relationships, new work contracts, conforming to government-issued regulations, balancing dispersed work groups, and more. A key aspect of such strategies resides in the efficient management of competing points of view, ideas, and perspectives. Therefore, flowcharts could feature spaces that accommodate multiple perspectives; the subsequent stages could select the best ideas from each perspective and incorporate these into business strategy. Such a tactic allows business operators to fashion competent stances that enable the enterprise to hone its competitive edge, offer winning propositions to clients, develop and retain human talent, and perform admirably in competitive markets.
Identifying the needs and requirements of clients and customers could provide critical impetus to the design, construction, and engineering underlying modern problem solving processes. This stance holds special meaning in service-oriented business processes. For instance, e-commerce operators could choose to re-design existing business systems and processes in a bid to preempt problems in processes such as doorstep delivery protocol, processing of invoices, managing shipping costs, quality of customer services, processing of in-app shopping carts, package return policies, and others. Flowcharts can assist in refining these processes and re-aligning these to uphold the interests of buyers and shoppers. Such re-alignment may trigger changes in the fundamental matrix of e-commerce enterprises, could require changes and alterations in the digital backend of the business, and may spark a revision of best practices endorsed by industry operators. The use of flowchart-based illustrations allows operators to obtain the best stance defined from customers' perspective.
This exposition allows readers to appreciate the agency of flowcharts in constructing balanced tactics and techniques that drive troubleshooting initiatives. The spaces and graded layers inherent in modern blueprints empower creators to locate problems, assess their impact on process performance, design damage assessment procedures, frame the outlines of solutions, and implement these inside systemic processes. Flowcharts also remain critical in evaluating the subsequent performance of processes, thereby adding momentum to problem resolution initiatives. |

Upon recognizing their specific antigen through the B cell receptor (BCR), B cells undergo a complex and tightly regulated process of activation. This activation is essential for initiating subsequent steps in antibody production, including clonal expansion and differentiation into various cell types. The activation process involves a cascade of intracellular signaling pathways triggered by the BCR complex. Following antigen binding, two primary signaling pathways are activated:
The B cell receptor (BCR) pathway: This pathway involves the activation of protein tyrosine kinases (PTKs) like Lyn and Syk. These PTKs, in turn, activate various downstream signaling molecules, including phospholipase C (PLCγ2). PLCγ2 hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) into inositol trisphosphate (IP3) and diacylglycerol (DAG). IP3 triggers the release of calcium ions (Ca2+) from the endoplasmic reticulum, while DAG activates protein kinase C (PKC). This intricate interplay of signaling molecules ultimately leads to the activation of transcription factors like NF-κB, AP-1, and IRF4.
The co-stimulatory pathway: This pathway is typically triggered by the interaction between CD40 ligand on T helper cells and CD40 on B cells. This interaction activates various signaling molecules, including protein kinase A (PKA) and NF-κB.1,2
These activated transcription factors then enter the nucleus and bind to specific DNA sequences, promoting the transcription of a multitude of genes involved in various processes:
Cell proliferation: Genes encoding proteins necessary for cell division, such as cyclin-dependent kinases (Cdks), are activated, leading to clonal expansion of the B cell population. This generates a large number of daughter cells, all specifically targeting the same antigen.
Differentiation: Genes directing the differentiation of B cells into various types are also activated. These types include:
Plasma cells: These specialized cells dedicate their entire machinery to producing large quantities of antibodies specifically targeted against the encountered antigen.
Memory B cells: These long-lived cells remain dormant but retain the memory of the specific antigen encountered. Upon future exposure to the same antigen, they can rapidly differentiate into plasma cells, providing long-term immunity.
Antibody production: Genes encoding the specific antibody heavy and light chains are also activated. These chains are assembled and undergo modifications to form functional antibodies tailored to neutralize the antigen.3
Following activation, B cells undergo clonal expansion, a rapid cell division process that generates a large number of daughter cells. This process is tightly regulated by various factors, including:
Transcription factors: Activated transcription factors, such as Myc and E2F, promote the expression of genes essential for cell cycle progression and DNA replication.
Growth factors: Cytokines like interleukin-2 (IL-2) and interleukin-4 (IL-4) released by T helper cells further stimulate B cell proliferation.

The Ardern Government's chickens came home to roost yesterday with the news that the country is short of natural gas.
In 2018, Labour banned offshore petroleum exploration, and industry executives say that the attendant loss of confidence by the industry impacted overall investment in onshore gas fields.
Energy Resources Minister Simeon Brown yesterday told Parliament that the gas now being produced was less than forecast.
Already this year, gas production was down 28 per cent compared to the forecasts produced by the Ministry of Business, Innovation and Employment.
Consequently, because we are likely to face a dry winter and thus will need more alternative generation to hydro dams, the Huntly thermal power station will have to import more coal.
Transpower said yesterday that national hydro storage had dropped to 99% of the historical average for this time of year.
Demand was 4.5% higher so there was an increase in hydro and thermal generation to supply increased loads.
"The renewable percentage of the generation mix dropped a further four points to 82% last week," their report said.
"Hydro generation increased and wind generation decreased (to 58% and 5% of the generation mix respectively, with thermal generation rising to supply the increased demand (to 15% from 11% the week prior)."
Huntly is the country's major thermal generator and Its operator, Genesis, confirmed in a statement yesterday that sector gas production across the country had been substantially declining, with major field production in April down 33.4% from a year ago.
"The decline has been faster than official forecasts predicted and is expected to continue.," the statement said.
"Huntly Power Station runs on gas and coal, so less gas creates the need to burn more coal."
The reason the gas came in below forecast is that the gas fields in the Taranaki are nearing the end of their life and require further investment to extract the dwindling supplies within them.
The CEO of Energy Resources Aotearoa, the petroleum lobby group, John Carnegie, told POLITIK last night that the Labour ban had a massive dampening effect on investment.
"The investment context, in general, was massively impacted," he said.
"And our risk profile went up, and it became harder to justify investment here."
But yesterday, Megan Woods, the Minister who implemented the ban without much consultation or extensive briefings from officials, was defending it.
"New Zealand has a finite supply of fossil gas," she said.
"In fact, the Gas Transition Plan—a plan released under our Government to address the challenges in front of us—noted even with ongoing investment, supply could decrease over time because our major gas-producing fields are in a natural production decline phase in their operational lives."
To help deal with the current emergency, the major industrial gas user, Methanex, is cutting gas input into its Waitara plant and lowering production and, therefore, exports.
The plant has an annual capacity of 2.2 million tonnes of methanol, which is currently sold on the Asian market at up to $US400 per tonne.
Transpower yesterday released a draft of its Security of Supply Assessment, which assumes that Methanex will continue to be able to reduce production to free up gas for use at Huntly.
"Unless there is sufficient development of the consented and unconsented pipeline to bring more (generation) supply to market, we are dependent on thermal generation (including sufficient fuel for its operation during dry years) to maintain the winter energy margin (NZ-WEM) above the lower security standard over the duration of the assessment horizon," the report said.
"The required contribution from the supply pipeline reflects an increase in the rate of renewable build compared to recent years."
But this best-case scenario, which is heavily dependent on a large-scale increase in construction activity, would still be heavily reliant on Methanex reducing its gas consumption.
"The reduced gas availability sensitivities highlight that the NZ-WEM could drop below the standards in the near term (2025) unless there is sufficient gas flex from industrial gas users to support increased gas-fired electricity generation during dry years," it said.
Genesis Chief Executive Malcolm said increasing levels of intermittent renewable generation from wind and solar farms cause a yo-yo effect on thermal generation, requiring it to swing in and out of operation in an unpredictable way, driven by fluctuating wind and sunshine.
He said Genesis would invest $1.1 billion in new renewable solar and wind generation, grid-scale batteries, and the establishment of a biomass supply chain to gradually move its solid fuel stockpile toward biomass at Huntly Power Station.
"The solid fuel transition toward lower carbon options like biomass will take some years, and during this transitionary period, to ensure energy security and stability, there will be a need to use some coal, with imported options currently being the most efficient for the quantity we need," said Johns.
Under its new strategy, Genesis has indicated that it intends to maintain an operating stockpile of solid fuel at Huntly Power Station of around 350,000 tonnes, or about 670 GWh of electricity. This will enable it to continue backing up increasing renewable generation from wind and solar farms during the energy transition.
"The solid fuel stockpile will fall below 350,000 tonnes by the end of winter. This will trigger a need to order more solid fuel deliveries to maintain the target operational stockpile ahead of the winters of 2025 and 2026. Imported options have a delivery time of around three months.," he said.
In 2022, New Zealand imported 726,838 tonnes of coal.
And that is the irony. In 2017, just before Woods implemented the exploration ban, New Zealand imported only 466,000 tonnes of coal, producing twice as much carbon dioxide per tonne as natural gas.
Carnegie is adamant the industry needs more exploration.
"What we need is an investment in new exploration to boost, shift or do two things: shift those contingent gas reserves into proven and probable reserves," he said.
"And so you're basically relying on your incumbents to do that.
"Because they're here, and they can do it.
"And then obviously you've got the medium to longer-term hope of new entrant investors coming in for new fields, new permits, new exploration, new discoveries."
Brown told Parliament yesterday that the government was open to that.
"The coalition Government is committed to returning investment confidence in the natural gas sector so we can continue to produce the energy that powers our industries and keeps the lights on when renewables cannot do it alone," he said.
"The Minister for Resources, Hon Shane Jones, and I are working on a set of legislative reforms to support the gas sector that we look forward to introducing to the House.
"This includes taking decisions on the removal of the ban on offshore oil and gas exploration." |
How Web Development Companies are Utilizing Full-Stack Approach to Offer Comprehensive Web Solutions
In the dynamic world of web development, versatility and comprehensive skill sets are paramount. Full-stack web development, an approach that encompasses both front-end and back-end development tasks, is becoming increasingly essential for web development companies.

Giardia and Cryptosporidium are important causes of diarrhoea in Bangladesh. The high prevalence of both parasites in humans and cattle in rural Bangladesh and the common use of water ponds by village inhabitants and their animals suggest a potential for zoonotic transmission. Direct transmission of Giardia and Cryptosporidium between cattle and their handlers and indirect transmission through water ponds was investigated. Faecal/stool samples were collected from 623 calves and 125 calf handlers in a cross-sectional survey. In two villages, water samples were collected monthly from water ponds and faecal/stool samples were collected monthly from inhabitants and their cattle. Giardia cysts and Cryptosporidium oocysts were detected in water samples and in faecal/stool samples and positive samples were genotyped, to determine their human or animal origin. The prevalence of Giardia and Cryptosporidium in calves was 22% and 5% respectively. In calf handlers, the prevalence of Giardia and Cryptosporidium was 11.2% and 3.2% respectively. Both in the cross-sectional survey and in the longitudinal study in the villages, G. duodenalis assemblage E was most prevalent in calves, while in humans assemblage AII, BIII and BIV were found. In cattle, Cryptosporidium parvum, C. bovis and C. andersoni were identified, but no Cryptosporidium sequences were obtained from humans. Giardia and Cryptosporidium were detected in 14/24 and 12/24 water samples respectively. G. duodenalis assemblage E and BIV (-like), as well as C. andersoni and C. hominis were identified. Although the presence of Giardia and Cryptosporidium in both water ponds suggests that water-borne transmission of Giardia and Cryptosporidium is possible, the genotyping results indicate that there is no significant direct or indirect (water-borne) transmission of Giardia between cattle and people in this area of rural Bangladesh. No conclusions could be drawn for Cryptosporidium, because of the low number of sequences that were obtained from human and water samples.

Diarrheal diseases are a serious public health problem, affecting mainly children in developing countries [1, 2]. Several bacterial, viral and parasitic agents are responsible for diarrheal disease, including Giardia and Cryptosporidium [3, 4]. Susceptible hosts are infected either through contact with an infected host or indirectly by oral intake of infective (oo)cysts through contaminated water or food. Among the eight assemblages (A-H) of Giardia duodenalis, assemblages A and B are found in both humans and animals. The occurrence of the same species/genotypes in human and non-human hosts (dogs, cats, livestock and wildlife) in the same geographical areas supports the potential for zoonotic transmission [5]. Most cases of human cryptosporidiosis are due to infections with the human specific C. hominis or the zoonotic C. parvum [6]. Other Cryptosporidium species have also been detected in humans, although less frequently [7–9]. Current evidence indicates that ruminants are a reservoir of zoonotic Cryptosporidium from where humans get infected by contaminated food and water or through direct contact with livestock, for example animal handlers [10, 11].
In Bangladesh, both Giardia and Cryptosporidium have been associated with diarrhea [12–15]. In cases of giardiosis, mainly G. duodenalis assemblage A was associated with diarrhea [14, 15]. Cryptosporidium hominis as well as C. parvum were identified in patients with diarrhea [15]. The studies mentioned above were all performed in Dhaka, one of the fastest growing megacities of the world. The presence of overpopulated slums and the pollution of neighbouring rivers with untreated wastewater [16, 17] could facilitate (water-borne) human-to-human transmission.
In rural Bangladesh, Giardia infections have also been associated with diarrhea in children [18]. In rural villages of Bangladesh, there are many smallholder cattle farms consisting of 1–5 animals for milk and draft purposes. A previous study found a high prevalence of Giardia and Cryptosporidium in cattle in Bangladesh [19]. Young calves are considered as a reservoir for these parasites, and transmission of Giardia and Cryptosporidium from cattle to cattle handlers has been suggested in Bangladesh and India [19, 20]. In addition, people living in rural villages have no or limited access to purified tap water and therefore rely on surface water from ponds or tube wells for their water supply. As water from tube wells is often contaminated with arsenic [21], surface water is often the only alternative. These small ponds are used for daily household purposes (e.g. swimming, washing of cloths, bathing cattle, cleaning vegetables, fish, utensils etc.). Faeces from cattle that are kept alongside of these ponds are often washed and drained into the ponds. Some households use latrines of which the outlets flow into the ponds. The above-mentioned scenarios indicate that there is a potential for water-borne transmission of Giardia and Cryptosporidium. However, no studies are available on transmission of Giardia and Cryptosporidium in these settings.
The aim of this study was to investigate potential direct transmission of Giardia and Cryptosporidium between cattle and their handlers and indirect water-borne transmission of Giardia and Cryptosporidium between the inhabitants and their animals in rural villages in Bangladesh.
Materials and Methods
Sampling design
Giardia and Cryptosporidium in calves and their handlers. A cross-sectional study was carried out to investigate the prevalence of Giardia and Cryptosporidium in calves (during March and April, 2009 and from March, 2012 to February, 2013) and their handlers (from July, 2012 to February, 2013) in Sadar Upazilla, Mymensingh District, a rural area in the Northeast of Bangladesh. Since there is no livestock database in Bangladesh, the first step of the sampling process was the digitisation of the map of Mymensingh district using ArcView Version 3.2 (Environmental Systems Research Institute, Inc. Redlands, California) which was previously carried out [22]. All 13 unions (sub Upazilla) namely Baera, Bhabkhali, Char Ishwardia, Char Nilaxmia, Khagdahar, Kustia, Sirta, Ashtadhar, Bobar Char, Dapunia, Ghagra, Paranganj and Sadar Upazilla, Mymensingh district were selected. One geographical coordinate was randomly selected from 10 previously selected coordinates in each union using the random number generation function in Microsoft Excel and located by a hand held GPS reader. Livestock farmers within a 0.5 km radius of the selected point were informed about this study [23]. To encourage livestock farmers to participate, free anthelmintics and vitamin-mineral premix were supplied to their animals when sampling took place. Rectal faecal samples from 30–40 calves aged between 5 days and 6 months were collected from each union. The specimens (n = 623) were labeled as par ear tag of individual calves and immediately transported to the laboratory of the Department of Medicine, Bangladesh Agricultural University, Mymensingh. The calf handlers (n = 125) were provided with sterile wide-mouthed plastic containers for collection of stool specimens. All specimens were kept at 4°C and processed within 24 hours of collection. All animals and individuals were healthy at the time of sampling.
Water-borne transmission of Giardia and Cryptosporidium in two rural villages. To investigate potential water-borne transmission of Giardia and Cryptosporidium, samples were collected from water ponds in two villages, as well as from inhabitants from households using these ponds and from their cattle. These two villages, Bhabkhali and Digarkandha, are situated in Mymensingh District (Fig. 1). Both villages have a population of about 4,000 persons in 800 households. Almost every household keeps 1–5 cattle for milk and draft purposes alongside the water ponds. These small ponds are used for household purposes and as main sources of water supply. Like in most of rural Bangladesh, the villages rely mainly on hand-pumped water for drinking and on surface water sources for other domestic and personal purposes. As hand-pumped tube wells are often contaminated with arsenic, villagers rely on surface water as an alternative. The ponds were selected on the basis of availability of water in all seasons and frequent use of the ponds by surrounding village people and their animals. A grab water sample (15L) was collected from one pond in each village every month at the same place from March, 2012 to February, 2013 and all samples (n = 24) taken immediately to the laboratory.

Rectal faecal samples from 10 cattle and 10 human stool samples were randomly collected without any age and sex restriction per month in each village from March, 2012 to February, 2013. In March 2012, exceptionally 20 cattle and 20 humans were sampled instead of 10, resulting in a total of 130 human and 130 cattle samples. All sampled individuals and animals were healthy at the time of sampling. The specimens were labelled as par ear tag of individual cattle and name of the person and immediately transported to the laboratory. All specimens were kept at 4°C and processed within 24 hours of collection.
Detection of Giardia cysts and Cryptosporidium oocysts in faecal/stool samples
Faecal samples were examined using a quantitative immunofluorescence assay (IFA; Merifluor Cryptosporidium/Giardia kit; Meridian Diagnostics Inc.) [24]. In short, 1g of faecal sample was suspended in distilled water and strained through a layer of surgical gauze to withhold large debris. After sedimentation for 1h and centrifugation at 3000g for 5 min, the sediment was resuspended in distilled water up to a volume of 1ml. After thorough vortexing, an aliquot of 20μl was pipetted onto a treated IFA-slide. After staining the slide, as instructed by the manufacturer, the entire smear was examined at a 400x magnification under a fluorescence microscope. The number of G. duodenalis cysts per gram faeces was obtained by multiplying the total number of cysts on the smear by 50. A sample was considered to be positive when at least one G. duodenalis cyst was found on the IFA slide.
Detection of Giardia cysts and Cryptosporidium oocysts in water samples
A protocol was optimised to detect Giardia and Cryptosporidium in water samples, based on the USEPA method 1623 [25]. To validate the protocol, spiking experiments were performed with water samples collected from Diagarkandha and Bhabkhali in March and November 2012. Water samples were spiked with 100 inactivated Giardia cysts and 100 inactivated Cryptosporidium oocysts, permanently labeled with red fluorescent dye (ColorSeed, BTF Pty Ltd., North Ryde, Australia). The ColorSeed (oo)cysts were added to each water sample prior to filtering to estimate the percent recovery of (oo)cysts according to the manufacturer's instructions.
Both spiked (15L) and non-spiked water samples (15L) were filtered through Filta-Max filters (IDEXX Laboratories, Inc., Westbrook, ME, USA) with the aid of a motorized peristaltic pump with recommended flow rates of 2L/min. The Filta-Max filters were washed with the Filta-Max manual wash station for elution of the filters following the manufacturer's instructions. The eluate was centrifuged and the sediment was used for immunomagnetic separation (IMS) of the (oo)cysts. Cysts and oocysts in the sediment were purified by IMS using Giardia and Cryptosporidium specific antibody-coated magnetic beads according to the manufacturer's protocol (Dynabeads GC-Combo, Invitrogen Dynal, A.S., Oslo, Norway). IMS-purified cysts and oocysts were stained on well slides by fluorescein isothiocyanate (FITC)-conjugated anti-Giardia and anti-Cryptosporidium MAbs FITC conjugated monoclonal antibodies (EasyStain, BTF Pty Ltd. Australia). Slides were examined using a Leica Leitz DMRB fluorescence microscope. The well surface was scanned at 200 or 400 times magnification for Giardia cysts and Cryptosporidium oocysts using a FITC/TRITC fluorescence filter (450–590 nm Chroma technology corp.) and Texas Red fluorescence filter (530–585 nm, FT600, LP615) to distinguish ColorSeed (oo)cysts (which fluoresce red with the Texas Red filter) from natural (oo)cysts (which fluoresce bright green with the FITC filter). Giardia cysts and Cryptosporidium oocysts were identified and counted based on their size, morphology and fluorescence. Results were expressed as recovery percentage for spiked (oo)cysts and as count per L for naturally occurring (oo)cysts. Slides containing (oo)cysts were kept at 4°C for DNA extraction.
DNA extraction and molecular analysis
DNA was extracted from non-spiked water samples and faecal samples from cattle and humans that were positive for Giardia and/or Cryptosporidium in immunofluorescence microscopy. Genomic DNA was extracted from water sediment and from faecal/stool samples using the QIAamp Stool Mini Kit (Qiagen GmbH, Hilden, Germany) and from (oo)cysts that were scraped from the microscope slides from water samples by the QIAamp DNA Mini Kit (Qiagen GmbH, Hilden, Germany) according to the manufacturer's instructions, incorporating an initial step of 3 freeze-thaw cycles (freezing in liquid nitrogen for 5 min and heating at 95°C for 5 min) in the protocol to maximize disruption of (oo)cysts.
For the identification of Giardia the β-giardin gene [26] was used in 2-step nested PCR. In addition, the triose phosphate isomerase (TPI) gene was used for assemblage-specific amplification of Giardia, [27,28,29]. Previously described PCR protocols were used to amplify the 18S rDNA gene [30,31] and the 70 kDa heat shock protein (HSP-70) gene [32] of Cryptosporidium. For subgenotyping of C. parvum and C. hominis positive samples, the 60kDa glycoprotein (GP60) was targeted [33]. For all PCR reactions, negative (PCR water) and positive controls (genomic DNA) were included. The PCR products were visualized in agarose gel (1.5%) stained with ethidium bromide under UV light. PCR products were fully sequenced by the BIG Dye Terminator V3.1 Cycle sequencing Kit (Applied Biosystems). Sequencing reactions were analysed on a 3100 genetic Analyzer (Applied Biosystems) and assembled with the program Seqman II (DNASTAR, Madison WI, USA). To determine the subgenotype the fragments were aligned with homologous sequences available in the GenBank database, using MegAlign (DNASTAR, Madison WI, USA).
Statistical analysis
The χ2-test was used to compare infection rates of Giardia and Cryptosporidium in calves and humans between the wet season (mid April-mid October, mean rainfall 278 mm, mean temperature 29°C) and the dry season (mid October-mid April, mean rainfall 42 mm, mean temperature 23°C). Mean (oo)cyst counts in water samples from both villages were compared between seasons using a related-samples Wilcoxon signed rank test. All analyses were done using the SPSS statistical programme. Values of p < 0.05 were considered statistically significant.

Giardia and Cryptosporidium in calves and calf handlers
A total of 623 faecal samples from calves were collected during the study period. The prevalence of Giardia was 21.7% (95% Confidence Interval (CI): 18–25%), with a mean cyst excretion of 55,038 cysts per gram (CPG) in infected animals (range 50–250,000 CPG). The prevalence of Cryptosporidium was 5.0% (95% CI: 3.7%-6.7%) with an average excretion of 1,534 oocysts per gram (OPG) (range 50–25,000 OPG). Giardia and Cryptosporidium infection rates were not significantly different between seasons. In the wet season, 21.1% of calves were positive for Giardia (83/393), compared to 22.6% (52/230) positive calves in the dry season (χ2 = 0.236, d.f. = 1, p > 0.05). Similarly, 4.8% (19/393) calves were positive for Cryptosporidium in the wet season, compared to 5.2% (12/230) Cryptosporidium positive calves in the dry season (χ2 = 0.004, d.f. = 1, p > 0.05). Giardia sequences were obtained from 60 out of 135 samples that were positive in IFA. The molecular characterization indicated a high prevalence of G. duodenalis assemblage E (47/60, NCBI accession numbers KJ188040-KJ188084, KJ363342-KJ363377) in calf samples. Other G. duodenalis assemblages found were AI (10/60, NCBI accession numbers KJ188032-KJ188039, KJ363378, KJ363379) and B (3/60, NCBI accession numbers KJ363380-KJ363382), often in mixed infections with assemblage E (5/60). Genotyping of Cryptosporidium positive samples (n = 5) revealed the presence of C. parvum (2/5, NCBI accession number KJ363386), C. bovis (1/5, NCBI accession number KJ363383) and C. andersoni (2/5, NCBI accession numbers KJ363384, KJ363385). Both C. parvum samples that were successfully amplified in the GP60 PCR belonged to sub type IIdA16G1 (NCBI accession numbers KJ363387, KJ363388).
Giardia cysts were detected in 14 out of 125 calf handler's stool samples (11.7%, 95% CI: 5.7–16.7%) with a mean cyst excretion of 33,168 CPG (range 50–250,000 CPG) and Cryptosporidium oocysts in 4 samples (3.3%, 95% CI: 1.1%-6.3%), with an average excretion of 275 OPG (range 50–450 OPG). Out of 14 positive samples, 6 samples were successfully sequenced for Giardia. Assemblages AII (2/6, NCBI accession numbers KJ188085, KJ188091), BIII (1/6, NCBI accession number KJ188086), BIV (2/6, NCBI accession numbers KJ188087, KJ188094) or a combination of AII, BIII and BIV (1/6, NCBI accession numbers KJ188088, KJ188089, KJ188092, KJ188093) were detected. None of the 4 Cryptosporidium samples could be amplified in the PCR reactions.
Giardia and Cryptosporidium in water ponds and faecal samples from village inhabitants and their cattle
Water samples. Slightly higher recovery rates were obtained for Giardia than for Cryptosporidium, which is in agreement with previous observations [25, 34]. Mean recovery percentages (with standard deviation) for Giardia and Cryptosporidium were 41±6% and 40±2%, respectively. Recovery rates for both parasites met the standards set by USEPA, 2005.
A total of 24 water samples (12 from Bhabkhali and 12 from Digarkandha) were collected over a period of 1 year. Giardia cysts were detected in 14/24 samples, whereas Cryptosporidium oocysts were detected in 12/24 water samples. Both ponds were contaminated with Giardia and Cryptosporidium. Giardia cyst counts in positive samples ranged from 0.1/L to 6.5/L in Bhabkhali and between 0.4/L and 11.3/L in Digarkandha. Cryptosporidium oocyst counts varied between 0.3/L and 0.7/L and between 0.2/L and 1.1/L in Bhabkhali and Digarkandha, respectively. Although (oo)cyst counts in Digarkandha appeared to be higher in the wet season, these differences were not statistically significant (p > 0.05) (results not shown).
Samples that contained at least one (oo)cyst detected by IMS-IFA were selected for genotyping. A total of 11 positive water samples for Giardia (6 from Bhabkhali and 5 from Digarkandha) and 9 samples for Cryptosporidium (4 from Bhabkhali and 5 from Digarkandha) were selected for PCR. Giardia sequences were obtained from 5 positive water samples. Most sequences belonged to assemblage E (n = 4; 2 from each village). One sample from Digarkandha could not be differentiated between assemblage BIV and BIV-like and was possibly a mixed infection. C. hominis (NCBI accession numbers KJ363330, KJ363331) and C. andersoni (NCBI accession number KJ363329) were identified in 2 and 1 samples from Digarkandha respectively. No successful sequence for Cryptosporidium was obtained from Bhabkhali water samples.
Cattle samples. The Giardia infection rate in cattle in Digarkandha was 13.3% (95% CI: 7.3%-19.4%), with a mean cyst excretion in positive animals of 22,075 CPG (range 50–125,000 CPG), compared to 5.0% (95% CI: 1.1%-8.9%) with a mean cyst excretion of 900 CPG (range 50–3750 CPG) in Bhabkhali. Cryptosporidium infection rates were 9.2% (95% CI: 4.0%-14.3%) with a mean excretion of 150 OPG (range 50–600 OPG) and 5.0% (95% CI: 1.1%-8.9%) with a mean excretion of 8417 OPG (range 50–35,000 OPG) in Bhabkhali and Digarkandha, respectively. No significant associations between season and infection rates were observed (p > 0.05) (Table 1).
A total of 22 positive samples for Giardia were selected for PCR (6 from Bhabkhali and 16 from Digarkandha). Most sequences belonged to assemblage E (n = 7; 1 from Bhabkhali and 6 from Digarkandha, NCBI accession numbers KJ363394-KJ363397 and KJ363338-KJ363341). In Digarkandha, one sample was identified as AI (NCBI accession number KJ363336) and one sample had mixed infections of assemblages AI and B (NCBI accession numbers KJ363393, KJ363337). Out of 17 samples that were positive for Cryptosporidium, C. andersoni was detected in one sample in each village (NCBI accession numbers KJ363327, KJ363328) and Cryptosporidium horse genotype in one sample from Bhabkhali (NCBI accession number KJ363326).
Human samples. Infection rates with Giardia and Cryptosporidium were similar in inhabitants of both villages. Giardia infection rates were 11.7% (95% CI: 9.3%-22.4%) with a mean excretion of 39,950 CPG (range 50–400,000 CPG) and 15.8% (95% CI: 9.3%-22.4%) with a mean excretion of 67,329 CPG (range 50–1,000,000 CPG) in Bhabkhali and Digarkandha, respectively. Cryptosporidium was detected in 6.7% (95% CI: 2.2%-11.1%) of human stool samples in Bhabkhali (mean 11,638 OPG, range 50–80,000 OPG) and 5.0% (95% CI: 1.1%-8.9%) of human samples in Digarkandha (mean 325 OPG, range 50–1000 OPG). Although Giardia and Cryptosporidium infection rates appeared to be higher in the rainy season in both villages (Table 2), differences between seasons were only statistically significant for Cryptosporidium in Bhabkhali (χ2 = 6.03, d.f. = 1, p < 0.05) and Giardia in Digarkandha (χ2 = 6.79, d.f. = 1, p < 0.01).
A total of 33 positive samples for Giardia were selected for PCR (14 from Bhabkhali and 19 from Digarkandha). Giardia sequences were obtained from 6 positive samples (2 from Bhabkhali and 4 from Digarkandha). All sequences belonged to assemblage BIII (n = 3; all from Digarkandha, NCBI accession numbers KJ363334, KJ363390, KJ363391), BIV (1 sample from Bhabkhali, NCBI accession number KJ363335) or a mixed infection of assemblage BIII and BIV (1 in each village, NCBI accession numbers KJ363332, KJ363333, KJ363389, KJ363392). No PCR products were obtained for Cryptosporidium.
The prevalence of Giardia in calves was higher compared to Cryptosporidium in the cross-sectional study. A possible reason was the age range of the calves, as Cryptosporidium infection rates are typically highest in calves younger than one month [35, 36] while a large proportion of the calf population in the present study was older than one month. It should be noted that the estimated prevalence in the cross-sectional study could have been affected by intermittent shedding of (oo)cysts, as all subjects were only sampled once.
Higher infection rates in calves were previously observed in the rainy season and in autumn in Bangladesh, India and Pakistan [19, 36–38]. The warm and humid conditions may favour survival of (oo)cysts, and heavy rainfall and flooding may facilitate transmission of the infections. Although in our study infection rates in cattle were not significantly different between the wet and the dry season, a seasonal pattern in Giardia and Cryptosporidium infections was observed in the village inhabitants. Similarly, higher Cryptosporidium infection rates in human patients during the rainy season have been reported previously in Bangladesh [12].
A significant association between the occurrence of Cryptosporidium and Giardia infections in calves and calf handlers has been documented in previous studies in Bangladesh and in West Bengal, India [19, 20]. However, in this study no evidence was found of direct zoonotic transmission between calves and their handlers. The cattle handlers were almost exclusively infected with G. duodenalis assemblage AII and BIII, while the calves were predominantly infected with the hoofed livestock-specific assemblage E, and to a lesser extent with assemblage AI. The other assemblages that were occasionally found in cattle (BIV, BIV-like) are also found predominantly in animals [39]. Furthermore, mainly bovine Cryptosporidium species were identified in the calves, although two samples belonged to a C. parvum subtype that has also been reported in human cases (IIdA16G1).
In both villages, water samples from the ponds were frequently contaminated with Cryptosporidium and Giardia. However, since no viability staining was performed on the detected (oo)cysts, it cannot be excluded that some of the detected (oo)cysts were dead.
No evidence for zoonotic transmission of Cryptosporidium and Giardia between cattle and humans could be found in these environments with high potential for zoonotic transmission. In both villages, cattle were carrying predominantly animal-specific parasite species (C. andersoni, G. duodenalis assemblage E). Although the zoonotic assemblage AI was also detected in a few bovine samples, this assemblage is mostly found in animals [39], and was not identified in any human sample in Bhabkhali or Digarkandha. Similarly, Laishram et al. [40] did not find assemblage AI in children and adults in neighboring India. Only assemblage BIII and BIV were identified in the human population in these villages. Although these assemblages can also infect animals [39], they were not detected in any of the cattle samples. Together with the presence of C. andersoni, C. hominis and G. duodenalis assemblage E and (less frequently) BIV (-like) in the water samples, these data suggest that water-borne transmission of Cryptosporidium and Giardia may occur in Bhabkhali and Digarkandha, but that (water-borne) transmission cycles are predominantly within host species.
The present study demonstrated the presence of Giardia and Cryptosporidium in cattle and people in a rural area of Mymensingh, Bangladesh. Water ponds in rural villages were also contaminated with Cryptosporidium and Giardia, and may facilitate water-borne transmission of these parasites. However, no evidence was found of zoonotic transmission of Giardia from cattle to humans, either directly (between cattle and their handlers) or indirectly through the water ponds, suggesting that (water-borne) transmission cycles of Giardia in this area are predominantly within host species. Because of the low success rate of Cryptosporidium genotyping in human and water samples, no conclusions can be made about transmission patterns for this parasite.

Lottery is a low-odds game of chance or process in which winners are selected by drawing lots. It is a popular form of gambling, encouraging people to pay a small amount of money for the chance to win a large jackpot, often administered by state or federal governments. People also use lottery systems in decision-making situations, such as sports team drafts and the allocation of scarce medical treatment.
Despite the fact that the odds of winning are very slim, many people enjoy playing the lottery and spend a lot of time trying to find a strategy that will lead them to success. Some even believe that there is a way to beat the odds by carefully selecting numbers and stores to buy tickets at. Although these tactics may be of some help, there is no such thing as a mathematically perfect lottery strategy. There are some, however, that have managed to beat the odds. Romanian-born mathematician Stefan Mandel, for example, won the lottery 14 times and has shared his formula with the world. He claims that the key to winning is buying tickets with all possible combinations, which he calls a "binary matrix." The idea is to cover as many options as possible while at the same time keeping the total number of tickets purchased below a certain threshold.
It is important to remember that the odds of winning the lottery are very slim, and it is generally not a good idea to spend more than you can afford to lose. In addition to being irrational and mathematically impossible, lottery playing can have serious consequences for your financial health. In some cases, the influx of money from winning the lottery can cause people to spend more than they have and even to file for bankruptcy.
One of the reasons for this is that people tend to over-estimate their own chances of winning, especially if they have been playing for a long time. According to a recent study by the University of Michigan, people who play the lottery for more than 10 years are about eight times as likely to have been in debt as those who don't play. The study also found that high-school educated, middle-aged men are more likely to be frequent lottery players than any other demographic group.
Another reason for over-estimating the odds of winning is that people are not adjusting their expectations accordingly when they buy tickets. The advertised prize amounts are usually based on annuities, or payments that will be made over a set period of time. When interest rates are low, the value of an annuity will be higher and so the jackpot prize will appear larger than it would be otherwise.
Whether to choose a lump sum or annuity payment is also an important decision that should be based on your personal goals and the applicable rules. A lump sum can be used to fund investments immediately, while an annuity provides a steady flow of income over the course of your life. |
MPC and Its Role
The Monetary Policy Committee (MPC) plays a crucial role in shaping a country's economic landscape by formulating monetary policies. Comprising experts from various fields, MPC advises the government on crucial financial matters. Recently, MPC has released its pre-budget recommendations, outlining strategies for sustainable economic growth and development.
Importance of Pre-Budget Recommendations
Pre-budget recommendations serve as a roadmap for the government to address prevailing economic challenges effectively. They provide insights into key areas requiring attention and offer solutions to enhance fiscal stability and economic prosperity.
Overview of Government Budgets
Government budgets are comprehensive financial plans outlining revenue sources, expenditure allocation, and economic priorities for a specified period. These budgets play a pivotal role in driving economic growth, social welfare, and infrastructural development.
Understanding the MPC's Recommendations
MPC's recommendations are meticulously crafted after thorough analysis of economic indicators, market trends, and societal needs. These suggestions aim to streamline fiscal policies, optimize resource allocation, and foster a conducive environment for sustainable development.
Economic Analysis Behind MPC's Suggestions
MPC's recommendations are grounded in rigorous economic analysis, encompassing factors such as inflation rates, GDP growth projections, unemployment figures, and global economic trends. This analytical approach ensures informed decision-making and effective policy implementation.
Addressing Key Socio-Economic Issues

As everyone knows, senioritis hits like crazy the second juniors come back as seniors in the fall. There isn't much that anyone can say to a senior who is just over it entirely. This debilitating disease can even make it hard for senior to listen! Don't worry; "Senioritis" is common, normal, and easily treatable. After so many years in school, eventually it hits that you made it so far and are almost done. So, you basically take a back seat to school (which is not a good thing). So, here are some good tips to try to stay motivated:
The first tip is to keep up with deadlines! Try to be done with all your easy assignments that you know you can do before its time for the hard ones. That way, you feel like you can get them done a little easier. If you have a week to do one assignment and two days for another, get the one that's due sooner done first. You could also stay organized with a planner or set dates on your calendar. Make it a habit to check your planner frequently so you don't miss anything. If you use your calendar on your phone, though, make sure to turn on those notifications!
The second tip is that if you choose to go to college, keep it at the front of your mind all the time. Colleges can and will revoke acceptance and scholarships if you are failing. Your grades have to stay up. Remember, even if everything goes right and you go to college to play sports, you still have to have a back up plan. Not all players go pro, and pros will eventually retire. A good, solid education is helpful to living the life you want!
The most important tip yet is to just go to school. It is so easy for all your days to run together, and it feels like school is never over - but you still have to go. Missing class time causes bad grades. You can't complete work you don't know about, and you can't pass it if you weren't there to learn it. It is so easy to build a habit for bad attendance, and if it continues into college, you could fail very expensive classes.
Everyone has things in school they just don't understand, like commas or exponents, but you still have to try. Ask yourself after every lesson if you truly understand it. It's never embarrassing to ask questions - it's more embarrassing to just not try. If you just can't focus, remember your goals. If you don't have goals, set some, but make them achievable. Then, celebrate it every time you complete one.
School is a part of everyone's life, and it will be a part your own personal story. You can make any decision you want, so make them good. Don't let graduation day scare you; be prepared for it. Don't let the days fly by either; enjoy every second of such a huge chapter of your life.
Don't let life get ahead of you - stay motivated! |

Auto body shops that take quality seriously create a great impression on customers and insurance adjusters. It helps them keep shop rates reasonable and avoid unnecessary customer charges. However, achieving this goal requires disciplined follow-through on all jobs to meet OEM standards. The best way to do this is with detailed scheduling.
Paint is a decorative and protective coating that consists of pigments suspended in a vehicle, often a resin dissolved in a solvent. The car dries to form a tough film, binding the pigment to the surface. Some additives provide specific paint qualities like mildew resistance. The best body shops ensure each step in the process is done correctly, using a checklist to verify quality. It prevents expensive re-dos.
An auto body shop Denver CO must inspect every vehicle before moving it to the next stage of the repair. For example, the RPM will check vehicles when the body department finishes them before moving to the paint booth. This courtesy check not only ensures that the job was done correctly but also that there are no problems that would delay the painting process or cause issues with the quality of the finish. It prevents re-dos and boosts the customer's trust in the shop.
Inspections are an essential part of any auto repair. They safeguard customer trust while enabling shops to upsell recommended services and drive revenue. For example, courtesy checks are key for auto body shops to reassure customers that their vehicles were thoroughly inspected before they left the shop. Often, inspections involve reviewing the work that various departments within the shop perform. It's done by a designated manager or quality control technician who examines the work for defects and signs off on the task before it is moved to the next department.
Detailed checklists can cover everything from cosmetic accuracy to safety features. Checking that all paint nozzles are working properly is necessary to avoid costly do-overs. Verifying that suspension or wheel alignment was completed correctly can prevent issues. Some inspections even include a test drive to check that creature comforts like power seats and seat adjustment are functioning as expected.
Ensure that every step in the repair process is completed with quality. Aim for seamless repairs, cosmetic precision, and all components to work together properly. It requires a system to ensure the entire repair is done according to OEM specifications. It is the responsibility of the shop manager or the person who writes estimates in your shop. Checks can include seeing the right parts used to ensure the paint was properly prepped. Even things like guaranteeing the service caps have been replaced on radiator overflow tanks, air conditioning fittings and windshield washer fluid reservoirs. Similarly, checking that the plastic liners and shields that close out many underbody areas have been reinstalled.
A multi-point inspection checklist is a great way to build quality into the repair and keep track of important details that may be overlooked in the rush to complete the job. It is also an excellent tool for communicating with customers about the progress of their repairs and what was done to their vehicles.
It's important to check for quality every time a vehicle moves from one department to another. For example, a body technician should inspect a car before it goes to paint and again after it comes out of the spray booth. It ensures that technicians follow proper procedures for each process step. A courtesy check is an excellent way to earn customers' trust and boost shop revenue. These inspections identify additional work that might be needed on a car. It allows shops to expand their workload and increase the average repair order. The best auto body shops combine traditional expertise with advanced technology. Using software to access OEM repair specifications leads to more skilled technicians, more satisfied customers and a healthier bottom line. |

A Fifth Grade Builds Solar Cells!
What are solar cells? What do you need them for? Ulrike Witte answered these questions with a short lecture. She explained this with pictures that became visible piece by piece and let the students guess. This way, the pupils could participate from the very beginning.
Then the practical part began: the children were allowed to build small solar cells themselves, so-called dye solar cells. For this, two small pieces of glass are needed. These must be coated with a thin layer of tin dioxide so that they conduct electricity. Otherwise, you could not harvest the electric current that is generated in a solar cell.
But back to the manufacture of the solar cells. Liquid titanium dioxide is spread on one of the glass plates. You could also use toothpaste here, because it contains a lot of titanium dioxide. On the other hand, there are many other things in toothpaste, like the taste or colored stripes, which you don't need.
To dry the titanium dioxide, the platelet is placed on a hot plate so that the liquid evaporates. When the whole thing has cooled down, the glass plate with the dried titanium dioxide needs to be put into red hibiscus tea.
After two minutes, the pieceis taken out again and dried with a hairdryer. Using a towel would have damaged the applied layers and reduced the efficiency of the solar cell. The second piece of glass is painted with a pencil to apply a layer of graphite. Then both pieces of glass are pressed together with the coated sides facing inwards and stuck together with adhesive tape.
A liquid, the so-called electrolyte, must now be inserted between the glass plates so that the electrical current can flow. This completes the Farbstoffsolarzelle.
Now the children could measure how much voltage and how much current their self-made cells produce. Afterwards, they all compared their readings. "So, how much do you have?" could be heard shouted around the room.
After a short break, we continued. The children were able to visit three different stations in small groups. At one station, all the solar cells in the group were connected together and they tried to use them to power a calculator. The children were very amazed that it worked and wanted to test the calculator right away. They were also able to test solar toys.
At the second station, the children could try out how much energy they generate by riding a bicycle. Many found this very strenuous. They also compared their results with each other. "So, what did you run, one, two, three or four light bulbs?"
The last station was about how a solar cell works. To do this, the children first put together the cross-section of a solar cell from puzzle pieces. Many found this quite simple. Then came the explanation: There are electrons in the hibiscus tea, which get energy from the light. They migrate into the titanium dioxide layer. Thus they are missing from the hibiscus tea, which steals the electrons from the electrolyte. From the titanium dioxide layer the electrons go into the coating of the glass. They travel through a cable to a load, perhaps a light bulb, and back again through a cable into the graphite layer. Then they move back into the electrolyte, where a few electrons are missing. In the hibiscus tea, other electrons get energy again from the incident light and migrate into the titanium dioxide layer. Then everything starts all over again.
The children and I enjoyed the day very much and we learned a lot. I can only recommend the day.
Anna Hauschild, student intern.
Anna did her high school internship in the Public Relations Department at Helmholtz-Zentrum Berlin. She was also able to take part in the solar energy project day in the school laboratory, which was designed for a 5th grade class. |
What happens if I haven't been to the dentist in years? If you haven't visited the dentist in a while, you're not alone. Many people avoid going due to fear or lack of time. But skipping regular check-ups can lead to serious dental problems such as cavities, gum disease, and even tooth loss. In this article, we'll explore the consequences of neglecting your dental health and why it's important to see a dentist regularly.
Why Neglecting Dental Care for Years Could Affect Your Candidacy for Dental Implants
Neglecting dental care for years can have a significant impact on your candidacy for dental implants. Over time, poor oral health can lead to bone loss or gum disease, which can affect the success of dental implant surgery. When considering dental implant candidacy, dentists will evaluate the state of your teeth and gums, as well as the density and quality of your jawbone. If you have experienced bone loss or gum disease due to neglecting your dental health, your dentist may recommend additional treatments, such as bone grafting or periodontal therapy, before proceeding with dental implant surgery. Therefore, it's essential to prioritize regular dental check-ups, cleanings, and good oral hygiene habits to maintain healthy teeth and gums that are necessary for a successful dental implant procedure in the future.
Is it detrimental if you haven't visited the dentist in years?
Yes, it can be detrimental if you haven't visited the dentist in years and you are considering getting dental implants. Regular dental checkups are important for maintaining good oral health and identifying any potential issues that may affect the success of the implant procedure. A thorough dental exam can identify any underlying periodontal disease or decay that may need to be addressed before the implants can be placed. Additionally, if you have missing teeth for a long time, the jawbone may have started to recede, making it more difficult to place implants. Regular dental visits can help catch these issues early and prevent further damage to your oral health.
What are the consequences of not visiting a dentist for 10 years?
Not visiting a dentist for 10 years can have severe consequences for your dental health, especially when it comes to the possibility of needing dental implants. During this time, oral health problems such as cavities, gum disease, and tooth decay can go undetected and worsen. This can lead to tooth loss, which may require dental implant surgery to fix.
In addition to worsening oral health, neglecting regular dental check-ups can also increase the risk of other health problems. Many systemic diseases have oral manifestations, such as diabetes or HIV. A dentist can recognize these signs and make an early diagnosis, which can help you start treatment earlier and improve the outcome.
Lastly, avoiding dental care can also make dental implant placement more challenging. If you have lost a significant amount of jawbone density due to periodontal disease or tooth loss, you may need a bone graft before receiving implants. This procedure can add time and expense to the overall treatment process.
In short, not seeing a dentist routinely can lead to worsening oral health, missed diagnoses, and more complicated dental implant surgeries if needed. It is essential to prioritize regular dental visits to maintain optimal oral and overall health.
How long can you go without seeing a dentist?
It is not recommended to go without seeing a dentist for an extended period of time, especially if you have dental implants. While dental implants are a long-lasting and reliable solution for missing teeth, they still require regular maintenance and check-ups to ensure they remain healthy and stable. Most dentists recommend visiting them at least twice a year for routine cleanings and examinations. If left untreated, problems such as implant failure, gum disease, and decay can occur. It's important to stay on top of your oral health to avoid more significant issues in the future.
Is it ever too late to visit the dentist?
It is never too late to visit the dentist for dental implants. While it is ideal to receive dental implants as soon as possible after losing a tooth, there is no age limit or deadline for receiving this treatment. In fact, dental implants have been successfully placed in patients of all ages, ranging from young adults to seniors.
However, it is important to note that the condition of a patient's oral health may affect their candidacy for dental implant surgery. For example, patients with advanced gum disease or significant bone loss may require additional treatment before being eligible for implants.
Ultimately, the best way to determine whether dental implants are right for you is to schedule a consultation with a qualified implant dentist. They can assess your oral health and recommend a treatment plan that meets your individual needs. So, don't hesitate to visit the dentist for dental implant treatment, regardless of your age or dental history.
Frequent Questions
Can I still get dental implants if I haven't been to the dentist in years?
Yes, you can still get dental implants even if you haven't been to the dentist in years. However, it's important to note that you should schedule a comprehensive dental exam first to determine the health of your teeth and gums. If any issues are found, they will need to be addressed before moving forward with the implant procedure. Additionally, if you have been missing teeth for a long time, you may need additional procedures such as bone grafting to ensure there is enough bone to support the implant. It's important to work closely with a qualified dental professional to determine your individual treatment plan.
What are the potential risks or complications of getting dental implants after a long absence from the dentist?
Getting dental implants after a long absence from the dentist can have potential risks and complications. One of the major concerns is the condition of the jawbone. If there has been bone loss due to a long absence from the dentist, the jaw may not be strong enough to support the implant. In such cases, bone grafting may be necessary to build up the jawbone before implant placement. Additionally, there may be an increased risk of infection or inflammation if there has been previous dental decay or gum disease that was left untreated for a long time. Other possible complications include nerve damage, implant failure, and sinus problems. It's important to consult with a qualified dental professional to evaluate your dental health before getting dental implants.
Will my lack of regular dental check-ups affect the success rate of my dental implant procedure?
Yes, lack of regular dental check-ups can affect the success rate of your dental implant procedure. Regular dental check-ups and cleanings are important to maintain good oral health and prevent periodontal disease. If you have existing gum disease or other oral health problems, it can increase the risk of implant failure. Additionally, neglecting regular check-ups can lead to undetected problems that may affect the success of the implant, such as decay or infection. It is important to maintain good oral hygiene habits and attend regular dental check-ups to ensure the success of your dental implant procedure.
In conclusion, if you haven't been to the dentist in years, it is important to take action and schedule an appointment as soon as possible.

Knowing the specifics of your auto insurance policy is key to knowing how much coverage you have in the event of an accident. Each policy has different terms and limits on what it covers and the amounts payable.
Knowing these details before an accident happens is important to ensuring your coverage meets your needs. Awareness of your policy helps prevent surprises during the claims process, as you'll already know what your insurance does and does not cover.
Your auto insurance policy comes with certain limits on how much it will pay for different types of claims. These limits are critical in determining how much financial aid you can get after an accident. You also have deductibles you pay out of pocket before your insurance kicks in.
Selecting a higher deductible can shrink your monthly premiums, but it means paying more upfront when you file a claim. Balancing these costs with what you can afford and your risk level is essential.
When you submit a car insurance claim, the insurer will send an adjuster to evaluate the damage. The adjuster's job is to assess how much the insurance company should pay for the repairs based on the policy's terms.
Dealing with adjusters can be tricky; they are trained to minimize the amount the insurance company has to pay. It's important to be well-prepared and to know your rights and what your insurance policy covers.
If your insurance claim gets denied, it doesn't mean it's the end of the road. You can challenge the decision. Review the reasons for denial that your insurance provider has provided first. This might involve checking if there was a misinterpretation of the policy or if all the facts were considered.
If you think the denial was wrong, you can submit an appeal with your insurer. This involves submitting additional documentation and evidence to support your claim. If this doesn't resolve the issue, legal action might be needed.

With a faculty of nearly 50 researchers who together cover an extensive range of areas of economics, the Graduate School facilitates in-depth exploration of the issue of income inequality.
Trends in Studies at our School :
Disparity in opportunity and disparity of outcome
As the term "society of widening disparity" is now frequently used by mass media, there is a need to define what this term exactly means. Some researchers point to the fact that family income directly affects children's access to higher education, thus causing disparity in educational opportunity. Others emphasize differences in the outcome created by income disparity, which is best represented by the group referred to as the "working poor." However, it is certain that there is a close linkage between disparity in opportunity and disparity of outcome, and the mechanism behind this linkage should be explored.
Policy Evaluation
Faced with an increased budget deficit, the Japanese government is now pressed to curtail expenditure without lowering the quality of administrative services. Policy evaluation is a very efficient tool for enhancing the kinds of administrative services that are truly necessary for the public as well as for identifying less needed services, and the national government and local administrative bodies are already applying this tool. The Graduate School of Economics has been working with a number of local administrative bodies to evaluate a wide range of governmental policies.
Trends in Studies at our School :
Cutting waste in the use of taxpayer money
One example of policy evaluation is an input-output analysis of the economic impact of urban redevelopment projects. Also, cost-benefit analyses are conducted in a variety of fields including the development of infrastructure such as international conference halls, public services such as nursery centers and library services, municipal mergers, natural environment conservation, international cultural exchange activities, and many others.
Cultural Economics
It has been said that culture and economy are as incompatible as oil and water, but is this really the case? On the contrary, cultural factors today take on such great importance that they even affect national economic power. Therefore, students who acquire economic analytical skills in conjunction with a wide range of cultural topics will be fully prepared to play a leading role in today's society as specialists in both culture and economics.
Located in Kyoto, the cultural center of Japan, the Graduate School offers curriculum designed to equip students with skills in policy evaluation and advanced econometric analysis in all fields of studies where culture and economics are closely related, including: historical and traditional culture such as festivals and traditional performing arts; media and content industries; relations between multimedia society and arts, films and music; support for cultural activities by business and industry (philanthropic activities); and culture and religion.
Trends in Studies at our School :
Specialists with the ability to "translate" between arts and brands
Our goal is to inspire the people of our society to recognize the value of human achievements, as distinguished from natural phenomena, both tangible and intangible as well as material and spiritual. In this connection, how should we assess value and evaluate policy? Clearly, general textbook knowledge can be of little help for this purpose. Applying the approach and analytical methods of economic and social sciences, however, we can "translate" arts, brands, images, and religions into something economic administrative and manageable. How well this "translation" works depends on the individual's ability to integrate. Specifically, we can assess the hypothetical market of aesthetics, evaluating the value of brands and amenities, and of course, conduct direct cost-benefit analysis of assets, both tangible and intangible.
Kyoto, a town of arts and brands characterized by sophisticated sense and sensibilities, is an ideal place to develop the ability to translate human emotions through the process of value assessment and policy evaluation, which is the most needed core quality in the 21st century's society and economy, both in Japan and the world.
Traditions and the Regional Economy
Studies of traditions and regions are important because they help us to rediscover their diversity and uniqueness. At the same time, we should be able to ascertain the factors contributing to their uniqueness and the essence of their claim to be the "only one" in the world by the comparative method based on theoretical, philosophical, and historical studies.
What makes the "merchants' road in Naniwa" economically unique? Why does today's cozy urban lifestyle date from the 19th century England and how has it been established as the world's standard mode of living? How were the traditional townhouses of Kyoto associated with local industries?
The Graduate School of Economics aims to train personnel, who, with the ability to appreciate both universal and indigenous values, can play leading roles as competent globalists and specialists at home and abroad.
Trends in Studies at our School :
The strategic value of being "the one and only "!
By adding a temporal axis (intertemporal view) and a spatial axis (international and regional comparison) to the stereotypes of society and research, we can depart from ambiguous ideas and develop our career capitalizing on the strategic value of being "the one and only " of our kind. Kumazawa Banzan, an economist active in the early Edo Period (17th century) said that what is marvelous about research is that it enables us to absorb three dimensions, namely, time, place and social perspective. Indeed, by using an economic approach to compare the value of being "the one and only" in qualitative and quantitative terms, students can develop strategic strengths that will be effective both at home and abroad. Students who have explored the meanings of time, place and social perspective during their study of economics at the Graduate School are active at all levels of society, both internationally and locally. |

In the complex landscape of human physiology, acute pain serves as an intricate language, signaling distress and demanding our attention. Understanding the nuances of these signals is crucial for maintaining optimal health. In this comprehensive guide, we delve into the 10 common causes of acute pain that every individual should be aware of.
1. Musculoskeletal Strain and Injury
Among the leading culprits for acute pain is musculoskeletal strain and injury. Whether it's a sudden twist, a heavy lift, or an unexpected fall, these incidents can lead to pain that ranges from mild discomfort to severe agony.
2. Inflammation: The Body's Alarm System
Inflammation, a natural response to injury or infection, can manifest as acute pain. Conditions such as arthritis, tendonitis, and bursitis are characterized by heightened inflammation, triggering pain signals as the body works to heal itself.
Aspadol 100mg is used to help relieve moderate to severe short-term pain (such as pain from an injury or after surgery). It belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain.
3. Nerve Compression: The Silent Agony
Nerves, the messengers of the body, can be susceptible to compression. Conditions like herniated discs or carpal tunnel syndrome exemplify instances where nerves are under pressure, causing sharp and shooting pain that demands attention.
4. Visceral Pain: Internal Distress Signals
Deep within our bodies, organs can emit signals of distress through visceral pain. Conditions such as appendicitis, kidney stones, or gallbladder issues can manifest as acute pain, requiring prompt medical attention.
5. Postoperative Pain: Navigating the Path to Recovery
Surgery, while often necessary for health improvement, leaves the body in a state of recovery. Postoperative pain is a common aspect, varying in intensity based on the nature and extent of the procedure.
Aspadol 200mg is an opioid painkiller that helps to ease moderate to serious pain. You need to know that pain is an unpleasant sensory and expressive experience caused by your potential tissue injury.
6. Dental Woes: A Painful Predicament
Dental issues, ranging from cavities to abscesses, can cause intense acute pain. The intricate network of nerves in the oral cavity amplifies the sensation, necessitating timely dental intervention.
7. Trauma: The Aftermath of Injury
Physical trauma, such as fractures or dislocations, can inflict acute pain that is immediate and intense. Understanding the extent of the trauma and seeking appropriate medical care is vital for managing and mitigating this type of pain.
8. Infections: Battling the Microscopic Invaders
Infections, whether localized or systemic, can be a source of acute pain. From urinary tract infections to respiratory infections, the body's immune response often translates into discomfort and pain.
9. Referred Pain: Tracing the Origins
Referred pain occurs when the sensation is felt in an area distant from the actual source. Understanding the complex web of nerve connections is crucial for accurately identifying and addressing the root cause of this type of pain.
10. Psychological Factors: Mind-Body Connection
The intricate relationship between the mind and body cannot be overlooked. Stress, anxiety, and depression can manifest as physical pain, creating a complex interplay between psychological well-being and physical health.
In conclusion, acute pain serves as a multifaceted communication tool, revealing underlying issues within the body. Recognizing these 10 common causes of acute pain empowers individuals to take proactive steps towards better health. |
Cyclone Kirrily hovered over the Coral Sea collecting water for days, so where is the rain?
It's the case of the missing rain.
Now ex-Tropical Cyclone Kirrily came with similarities in formation and strength to Tropical Cyclone Debbie, which battered the coast in 2017, but the system largely held off on the predicted rainfall.
It was described by the Bureau of Meteorology (BOM) on Friday as "a wind event rather than a rain event", despite it initially forecasting localised daily rain totals between 200-300 millimetres within 24 hours after its coastal crossing.

Despite several flood watches in place and severe weather warnings, gauges around the impact zones remained relatively low.
Townsville recorded just 31mm within a 24-hour period on Friday, which coincided with when the eye of the storm passed through the city.
Some areas received more than 100mm, including 163mm in the 12 hours to 6:12am at Mt Garnett, and 129mm to 7:08am at Upper Poison.
One area that saw rain-induced flooding was Charters Towers, where emergency services rescued 14 people after they became trapped overnight.
Water police and firefighters launched a search mission after reports 10 adults and four children had been stranded near the rural town, south-west of Townsville.
Loading...Authorities said the group had gone "recreational driving" to observe the aftermath of ex-Tropical Cyclone Kirrily when they got stuck.
Police said two locals had attempted an unauthorised rescue in their own small vessel, which capsized.
They were able to get to land safely and the group was rescued by a local mustering helicopter.
No-one was injured.
While the weather system did not produce the big wet BOM has expected, it is jobs like these that have authorities warning communities they are "not out of the woods yet".
So where has all the cyclone's water gone?
Well, it's still in the system.
The Bureau confirmed moisture remained with ex-Tropical Cyclone Kirrily and it's expected to fall over the next few days.
Senior forecaster Angus Hines said as Kirrily continued its path through the northern interior of Queensland, it was likely to bring extensive wet weather.
"The system is expected to stay on the map producing rainfall for the next several days — even producing rain in the Northern Territory and northern parts of WA," Mr Hines said.
But there's been one key difference between ex-Tropical Cyclone Kirrily and ex-Tropical Cyclone Jasper, which may be reducing rainfall totals.
"Jasper was just stuck in the mud," the forecaster said.
"The system was stationary and stagnant across north Queensland and that's where we saw day after day of rainfall, with some places receiving over a metre of rain."
In comparison, ex-Tropical Cyclone Kirrily has been swift moving — maintaining a pace of 15-20kph — which has been evenly distributing totals.
"Because Kirrily has movement, it's not raining in one place for too long," Mr Hines said.
How are flood watches calculated?
Flood watches are based on how much rain is predicted to fall on an entire catchment, which feeds into a river.
"It's only if it looks like there's enough rain on the forecast to cause a river to respond or rise, that's when the bureau issues a flood watch," Mr Hines said.
"Then when it's actually raining, we use the gauges to see if rivers are rising above their usual flows and that's how we begin issuing minor, moderate and major flood warnings."
When a flood warning is issued, that means a river has already begun responding to rainfall, and it's intended to warn residents downstream of potential impacts.
While all eyes remain on ex-Tropical Cyclone Kirrily, the BOM said there could still be more cyclones to come this wet season.
"There's nothing in the short-term over the next seven days, but given we're only in January, it's likely we'll see further tropical development around the northern states of Australia," Mr Hines said.
"History does suggest there will probably be more cyclones in the next few months as we're still early in the season". |

What Cat Breeds Originated From Egypt?
Egypt is not only known for its ancient pyramids and rich history, but also for its unique cat breeds. One such breed is the Chausie cat, which made its first appearance in 1995. This newer Egyptian breed has gained popularity for its striking appearance and friendly nature.
The Chausie cat comes in three colors: black, brown tabby, and grizzled tabby. With their sleek and muscular bodies, these cats exude elegance and grace. They have a social and friendly disposition, making them comfortable around strangers and a great addition to any household.
One of the distinguishing features of the Chausie cat is its high energy level. These cats have an abundance of energy and love to play. Whether it's chasing balls or engaging in interactive toys, they are always ready for a fun-filled adventure.
Another Egyptian cat breed with a wildcat DNA is the African Wildcat. These cats have a remarkable physique, characterized by a strong torso, long tail, and large ears. Their appearance reflects their wild ancestry, giving them a unique and captivating allure.
African Wildcats are known for their exceptional agility and intelligence. They are extremely active and clever, always finding ways to keep themselves entertained. These cats have a natural instinct for climbing and can reach impressive heights. Their hunting skills are also highly developed, making them excellent predators.
Contrary to popular belief, the Sphynx cat breed does not have any direct connection to ancient Egyptian cats. Despite their name, these unique felines actually originated in Canada in the 1960s through selective breeding. The first Sphynx cat, named Prune, was born in 1966.
The Sphynx's hairlessness is a result of a natural genetic mutation. While they may appear completely bald, they actually have a fine layer of downy hair on their bodies, giving them a distinct texture. Due to their lack of fur, Sphynx cats require regular bathing to remove excess oils from their skin.
One of the most notable characteristics of Sphynx cats is their friendly and affectionate nature. They are highly social creatures and enjoy being around people and other pets. Their sociability makes them a popular choice for households with multiple animals or children.
In terms of health, Sphynx cats are generally robust. However, they may be prone to certain conditions such as hypertrophic cardiomyopathy and respiratory problems. Regular veterinary check-ups are essential to ensure their well-being.
Sphynx cats are an active breed and require mental and physical stimulation to prevent boredom. Engaging them in play and providing them with interactive toys can help keep them entertained. It's important to note that Sphynx cats have a higher body temperature compared to other breeds, which helps them stay warm.
Despite their lack of fur, Sphynx cats are not hypoallergenic. Allergies are typically caused by cat dander, not fur, so individuals with allergies may still experience symptoms around Sphynx cats.
Over the years, the Sphynx breed has gained popularity and is now recognized by major cat registries worldwide. Their unique appearance and affectionate nature have made them a favorite among cat lovers. So, while they may not have any connection to ancient Egyptian cats, Sphynx cats have certainly made a name for themselves in the world of feline breeds.

Egyptian Cat Goddess Bastet
In ancient Egypt, cats held a special place in society, and their significance was intertwined with the worship of the goddess Bastet. As we explore the connection between cats and the Egyptian pantheon, it is fascinating to delve into the various cat breeds that originated in Egypt.
One of the most well-known cat breeds from Egypt is the Egyptian Mau.

In ancient Egyptian mythology, Bastet was often depicted as a lioness or a woman with the head of a lioness. However, over time, her image evolved to that of a domesticated cat. This transformation reflects the reverence and adoration that the ancient Egyptians had for cats, as they saw them as the embodiment of Bastet's divine presence.
Today, the legacy of Bastet and the reverence for cats continue to thrive. Many people still worship Bastet and consider her the patron goddess of cats. Additionally, the Egyptian Mau, Abyssinian, and Baladi breeds are cherished by cat lovers around the world, serving as a living testament to the enduring influence of ancient Egyptian culture.
Is the Sphynx Cat Egyptian?
The Sphynx cat is often associated with Egypt due to its unique appearance resembling ancient Egyptian depictions of cats. However, it is important to note that the Sphynx cat breed did not actually originate in Egypt. Contrary to popular belief, the breed was developed in Canada in the 1960s through selective breeding.
The Sphynx cat's lack of fur is a result of a natural genetic mutation, rather than any direct historical connection to ancient Egypt. While the breed's appearance may resemble that of ancient Egyptian cats, it is purely coincidental.
It is fascinating to see how the Sphynx cat's appearance has led to the misconception that it is an Egyptian breed. This is a prime example of how visual cues can influence our perceptions and assumptions. The Sphynx cat's hairless appearance, almond-shaped eyes, and large ears may evoke images of ancient Egyptian cats, but it is important to separate fact from fiction.
Abyssinian cats, a breed of domestic cat, have long been associated with ancient Egypt. Their striking resemblance to the sacred cats depicted in ancient Egyptian art has led to speculation about their origins. While the exact history of Abyssinian cats remains debated, some theories suggest that they may have originated in ancient Egypt or Ethiopia.
The connection between Abyssinian cats and ancient Egypt is intriguing. These cats bear a striking resemblance to the feline companions depicted in ancient Egyptian art. Their slender bodies, almond-shaped eyes, and distinctive ticked coat patterns evoke images of the revered cats that were worshipped in ancient Egypt.
The origins of Abyssinian cats are shrouded in mystery. One theory suggests that British soldiers brought them back from Abyssinia (now Ethiopia) during the 19th century. However, there is no concrete evidence to support this claim. Another theory proposes that Abyssinians are descendants of cats from ancient Egypt, brought to Europe by traders or explorers. This theory aligns with the physical similarities between Abyssinians and the cats depicted in ancient Egyptian art.
It is worth noting that Abyssinians were not officially recorded until the 1800s. The breed gained recognition and popularity in the late 19th century, particularly in Britain. Abyssinians were exhibited at cat shows and quickly became a favorite among cat enthusiasts.
The allure of Abyssinian cats lies not only in their potential connection to ancient Egypt but also in their unique characteristics. They are known for their playful and active nature, as well as their affectionate and social personalities. Their short, ticked coats come in various colors, including ruddy, red, blue, and fawn. These cats have a regal appearance and a graceful presence that captivates cat lovers around the world.
Modern Egyptian Cat Breeds
In the world of cat breeds, Egypt has given us some fascinating and unique feline companions. One such breed is the Chausie cat, which made its first appearance in 1995. With its striking appearance and playful nature, the Chausie has quickly gained popularity among cat enthusiasts.
The Chausie cat comes in three distinct colors: black, brown tabby, and grizzled tabby. These colors add to the allure of this breed, making them stand out in any room. But it's not just their appearance that sets them apart; Chausie cats are known for their social and friendly nature. They are quick to warm up to strangers and enjoy being in the company of others.
When it comes to energy levels, Chausie cats have plenty to spare. They are always ready for a game of chase or to pounce on a toy. Their high energy levels make them a perfect companion for those who enjoy an active lifestyle and want a cat that can keep up with them.

Most Common Saxophone Bad Habits
I can pretty much guarantee that everyone watching this is guilty of at least a couple of these bad saxophone habits.
We all have bad habits that are holding us back from being better versions of ourselves. A lot of our practice time should be devoted to eliminating those bad habits and building good ones.
Here's a list of the 7 most common bad habits I see in saxophone players, myself included, and how to fix them.
Let me know in the comments which ones you're guilty of, and together, let's aim to fix them this year.
1. Biting Too Hard
This is almost universal. Even very experienced players will end up biting too hard in certain situations.
When we bite too hard on the reed, the sound gets pinched. The pitch goes very sharp, and we are prone to squeaking. Low notes and high notes also become much more difficult to produce clearly.
Here's the thing, we don't need to put a ton of pressure on the reed. Think of your lower lip as a stabilizing cushion that ideally allows the reed to vibrate as freely as possible while maintaining a solid tone that's in tune.
We want to aim for the least amount of pressure necessary to get that sound. As you relax your embouchure, the pitch will go down and get rounder and less pinched. You will likely need to push your mouthpiece further in as you correct the biting habit.
Why do we bite so hard?
There are a few reasons.
- Tired embouchure. Maintaining the correct amount of pressure on the reed does require a certain amount of strength in our face muscles. These get developed through time spent practicing, long tones can be very helpful for this. If our muscles are weak, they get tired quickly and we respond by biting down harder so the whole thing ends up spiraling out of control.
- We are playing on too hard a setup. The harder your reed, the more pressure you're going to have to maintain on it. This will tire you out faster. An easy to play setup with relatively soft reeds will help you break the biting habit.
- Stress and tension. When we play with physical tension because we are nervous or just tense, it usually results in biting. This brings us to the 2nd bad habit.
2. Tension
Removing tension from your body when playing the saxophone, or any instrument is a constant battle. It's something we all need to work on. That tension can result in biting down too hard on our reed which will produce a poor sound, but it also can cause all sorts of other issues not least of which is physical injury.
It is so important to learn to play with very relaxed hands, wrists, shoulders neck and everything else. Too much tension in your body while playing can result in repetitive strain injury, tendinitis, carpal tunnel syndrome and more.
Again, I use long tone practice to focus my attention on releasing any tension I might have in my body. Just playing one note at a time, allows me to become more aware of what areas need to be relaxed.
This is a great way to develop a good habit and then carry it over to other things you play. Besides messing with your sound and physical health, that tension can really mess with your rhythm which brings us to bad habit number 3.
3. Rushing
As you can see, a lot of these bad habits are connected, and if we're not careful we can end up with a chain reaction of problems.
Rushing is when you play your rhythms faster than the pulse of the music. It's when you get ahead of the beat.
This is also extremely common. The first step to correcting any of these bad habits is becoming aware that you are doing them. Everybody rushes the rhythm sometimes, listen carefully and focus on making your rhythms sync up with the underlying pulse.
Be aware that the natural tendency is to rush and that you will likely need to pull back a bit. The slower the tempo, the more we need to look out. At fast tempos, the tendency will often be to drag or play your rhythms slower than the underlying pulse so, that's another bad habit to be aware of and work on correcting in your practice sessions.
4. Poor Finger Position
When we play relaxed, our fingers will rest gently on the the key pearls in a naturally curved position. Problem is, once the music starts and we have to play all these different notes and rhythms, and we're worried about messing up, the first thing to go out the window is that finger position.
Again, I find playing long tones to be extremely helpful in building a habit of relaxed fingers that stay in contact with the keys. While playing a note like middle C for example, I only have one finger down, I'm practicing keeping all the other fingers relaxed and in their ideal position while playing that note.
The trick is to carry that feeling over to everything else you practice. And the even harder trick is to maintain that good habit when the music gets difficult and while under the stress of performances.
These first 4 bad habits are all related to tension. You can work on building good habits for all of these things at the same time. The key is to constantly remind yourself to stay relaxed. Practicing in front of a mirror is extremely helpful for all of these. Tension is always trying to creep back in to our playing so be vigilant.
5. Thinking Your Gear is the Problem
Everyone can relate to this on some level and we've all been guilty of blaming our equipment when things don't go well.
Now if you watch this channel you know that I'm into gear, and it is important that your gear is working for you. But, once you have a decent saxophone, mouthpiece and reed, the rest is up to you.
Yes, you can get little boosts from upgrading stuff, but great sound and technique come from putting the time in on the horn, end of story.
If you find yourself thinking that you can't sound good until you have that holy grail, Mark VI, 5 digit-serial number, original lacquer, American engraved saxophone with the original Vintage New York Meyer or Otto Link Slant Signature mouthpiece and reeds that were hidden away since the 1970s. Then you need to spend more time in the shed with whatever setup you have.
Unless of course you find that vintage 3 band Brilhart ligature, then of course you don't need to practice. Those things play themselves.
6. Not Taking Care of Your Instrument
When was the last time you had your horn looked at by a good repair technician? For most of you watching, it's been too long. All saxophones go out of adjustment slowly, over time. There are tons of moving mechanical parts, and materials that wear out.
Most saxophone players don't visit a repair shop until their instrument stops working.
For most people an annual check up will keep things working smoothly. When your horn is functioning correctly, it is so much more fun to play, and you get stuff done in the practice room. You can also count on it to work during those concerts.
Those of you who play a lot, should see your technician every 6 months.
7. Not Listening to Enough Music
As our world has become so full of distractions, it seems to me that we collectively spend less time just listening to music. In the old days before the internet, just listening to music was a very common activity. We used to say things like,
hey do you want to come over and listen to the new record I just got? And we would do that for fun.
In the days before Netflix, going out to hear live music at night was also something we would do for fun on a regular basis. These days it is harder and harder to break through all the distractions and just enjoy the experience of hearing music.
I am definitely guilty of this one but here's how I try to build better habits.
Carve out a time each day that you listen to music, which might mean less internet surfing or streaming tv. Check local listings for concerts and live music performances. Get tickets, mark your calendar and go to the shows. You'll be glad you did.
Now when it comes to correcting bad habits on the saxophone, so much of the process is in our head. Believe it or not, just repeatedly thinking positive thoughts about how you practice and perform goes a very long way towards developing the good habits we want.
