https://en.wikipedia.org/wiki/Arly-Singou | Arly-Singou is a large ecosystem in Burkina Faso. It encompasses the Arli National Park and the Singou Reserve. It is considered to comprise part of the most significant and important savanna woodland wildlife areas still existing in West Africa.
Fauna and history
In 1980, aerial counts revealed that the largest antelope population in the entire region inhabited the Arly-Singou complex. More recent studies indicate that the antelope population has been sustained by the end of the 20th century.
In 2003, herds of African elephant, buffalo, roan antelope, western hartebeest, oribi, Grimm's duiker, Buffon's kob, bushbuck, waterbuck, bohor reedbuck and groups of warthog, anubis baboon and Patas monkey were recorded in Arly-Singou during an aerial survey. In 2002, it was estimated that between 364 and 444 lions reside in Arly-Singou, based on information by local people. But census data were not available. In 2004, census data were still not available. Based on information by wildlife researchers, it was estimated that 50 to 150 lions reside in Arly-Singou.
Previously the endangered painted hunting dog, Lycaon pictus, occurred in Burkina Faso within the Arly-Singou ecosystem, but, although last sightings were made in Arli National Park, the species is considered extirpated throughout Burkina Faso.
The Arly-Singou project is considered to have taken a somewhat new initiative in structure, in regard to wildlife management undertakings funded by the government in the area. Howev |
https://en.wikipedia.org/wiki/Moreau%27s%20theorem | In mathematics, Moreau's theorem is a result in convex analysis named after French mathematician Jean-Jacques Moreau. It shows that sufficiently well-behaved convex functionals on Hilbert spaces are differentiable and the derivative is well-approximated by the so-called Yosida approximation, which is defined in terms of the resolvent operator.
Statement of the theorem
Let H be a Hilbert space and let φ : H → R ∪ {+∞} be a proper, convex and lower semi-continuous extended real-valued functional on H. Let A stand for ∂φ, the subderivative of φ; for α > 0 let Jα denote the resolvent:
and let Aα denote the Yosida approximation to A:
For each α > 0 and x ∈ H, let
Then
and φα is convex and Fréchet differentiable with derivative dφα = Aα. Also, for each x ∈ H (pointwise), φα(x) converges upwards to φ(x) as α → 0.

https://en.wikipedia.org/wiki/Tikker | A tikker, alternately spelled ticker, was a vibrating interrupter used in early wireless telegraphy radio receivers such as crystal radio receivers in order to receive continuous wave (CW) radiotelegraphy signals.
In the early years of the 20th century, before modern AM or FM radio transmission was developed, radio transmitters communicated information by radiotelegraphy; the transmitter was switched off and on by the operator with a telegraph key, producing pulses of radio waves, to spell out text messages in Morse code. Around 1905 the first continuous wave radio transmitters began to replace the earlier spark transmitters. The Morse code signal of the spark transmitter consisted of pulses of radio waves called damped waves which repeated at an audio rate, so they were audible as a buzz or tone in a receiver's earphones. In contrast the new continuous wave transmitters produced a signal consisting of pulses of continuous waves, unmodulated sinusoidal carrier waves, which were inaudible in the earphones. So to receive this new modulation method, the receiver had to produce a tone during the pulses of carrier.
The "tikker", invented in 1908 by Valdemar Poulsen, was the first primitive device that did this. It consisted of a vibrating switch contact between the receiver's detector and earphone, which was repeatedly opened by an electromagnet. It functioned as a crude modulator; it interrupted the signal from the detector at an audio rate, producing a buzz in the |
https://en.wikipedia.org/wiki/Zaurategrast | Zaurategrast (CDP323) is a small-molecule prodrug antagonist of the vascular cell adhesion molecule 1 (VCAM-1) binding to α4-integrins. It was originally developed by the British biopharmaceutical company Celltech plc. (now UCB S.A.) and was a putative new drug for oral treatment of multiple sclerosis.
In October 2006, UCB and Biogen Idec announced a collaboration to jointly develop and commercialize zaurategrast for the treatment of multiple sclerosis and other potential indications. In June 2009, development of zaurategrast was discontinued due to discouraging results of a Phase II clinical trial.
Mechanism of action
The mechanism of action of zaurategrast were believed to rely on preventing immune cells to migrate from blood vessels through the vessel walls to reach various inflamed tissues, including the brain. This mechanism is thought to prevent overshooting immune reactions and subsequent tissue damage as seen during uncontrolled immune cell migration as in multiple sclerosis. Zaurategrast has the same mechanism of action as the monoclonal antibody natalizumab.
Results in animal models
Zaurategrast was investigated in chronic experimental autoimmune encephalomyelitis (EAE) in mice. The drug was effective when given prophylactically (i.e., before the disease was induced in mice) and when given therapeutically (i.e., after outbreak of the disease) and reduced the disease severity significantly.

https://en.wikipedia.org/wiki/ADP-ribosylation | ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis.
Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, diphtheria toxin, and others.
History
The first suggestion of ADP-ribosylation surfaced during the early 1960s. At this time, Pierre Chambon and coworkers observed the incorporation of ATP into hen liver nuclei extract. After extensive studies on the acid insoluble fraction, several different research laboratories were able to identify ADP-ribose, derived from NAD+, as the incorporated group. Several years later, the enzymes responsible for this incorporation were identified and given the name poly(ADP-ribose)polymerase. Originally, this group was thought to be a linear sequence of ADP-ribose units covalently bonded through a ribose glycosidic bond. It was later reported that branching can occur every 20 to 30 ADP residues.
The first appearance of mono(ADP-ribosyl)ation occurred a year later during a study of toxins: the diphtheria toxin of Corynebacterium diphtheriae was shown to be dependent on NAD+ in order for it to be completely effective, leading to the discovery of enzymatic conjugation of a single ADP-ribose group by mono(ADP-ribosyl)transferase.

https://en.wikipedia.org/wiki/Phenyl-C61-butyric%20acid%20methyl%20ester | PCBM is the common abbreviation for the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester. It is being investigated in organic solar cells.
PCBM is a fullerene derivative of the C60 buckyball that was first synthesized in the 1990s. It is an electron acceptor material and is often used in organic solar cells (plastic solar cells) or flexible electronics in conjunction with electron donor materials such as P3HT or other conductive polymers. It is a more practical choice for an electron acceptor when compared with fullerenes because of its solubility in chlorobenzene. This allows for solution processable donor/acceptor mixes, a necessary property for "printable" solar cells. However, considering the cost of fabricating fullerenes, it is not certain that this derivative can be synthesized on a large scale for commercial applications.

https://en.wikipedia.org/wiki/Ecological%20resilience | In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil, and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. When such thresholds are associated with a critical or bifurcation point, these regime shifts may also be referred to as critical transitions.
Human activities that adversely affect ecological resilience such as reduction of biodiversity, exploitation of natural resources, pollution, land use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Interdisciplinary discourse on resilience now includes consideration of the interactions of humans and ecosystems via socio-ecological systems, and the need for shift from the maximum sustainable yield paradigm to environmental resource management and ecosystem management, which aim to build ecological resilience through "resilience analysis, adaptive resource management, and adaptive governance".

https://en.wikipedia.org/wiki/Sodium%20phenoxide | Sodium phenoxide (sodium phenolate) is an organic compound with the formula NaOC6H5. It is a white crystalline solid. Its anion, phenoxide, also known as phenolate, is the conjugate base of phenol. It is used as a precursor to many other organic compounds, such as aryl ethers.
Synthesis and structure
Most commonly, solutions of sodium phenoxide are produced by treating phenol with sodium hydroxide. Anhydrous derivatives can be prepared by combining phenol and sodium. A related, updated procedure uses sodium methoxide instead of sodium hydroxide:
NaOCH3 + HOC6H5 → NaOC6H5 + HOCH3
Sodium phenoxide can also be produced by the "alkaline fusion" of benzenesulfonic acid, whereby the sulfonate groups are displaced by hydroxide:
C6H5SO3Na + 2 NaOH → C6H5OH + Na2SO3
This route once was the principal industrial route to phenol.
Structure
Like other sodium alkoxides, solid sodium phenoxide adopts a complex structure involving multiple Na-O bonds. Solvent-free material is polymeric, each Na center being bound to three oxygen ligands as well as the phenyl ring. Adducts of sodium phenoxide are molecular, such as the cubane-type cluster [NaOPh]4(HMPA)4.
Reactions
Sodium phenoxide is a moderately strong base. Acidification gives phenol:
PhOH ⇌ PhO− + H+ (K = 10−10)
The acid-base behavior is complicated by homoassociation, reflecting the association of phenol and phenoxide.
Sodium phenoxide reacts with alkylating agents to afford alkyl phenyl ethers:

https://en.wikipedia.org/wiki/Calcium-sensing%20receptor | The calcium-sensing receptor (CaSR) is a Class C G-protein coupled receptor which senses extracellular levels of calcium ions. It is primarily expressed in the parathyroid gland, the renal tubules of the kidney and the brain. In the parathyroid gland, it controls calcium homeostasis by regulating the release of parathyroid hormone (PTH). In the kidney it has an inhibitory effect on the reabsorption of calcium, potassium, sodium, and water depending on which segment of the tubule is being activated.
Since the initial review of CaSR, there has been in-depth analysis of its role related to parathyroid disease and other roles related to tissues and organs in the body. 1993, Brown et al. isolated a clone named BoPCaR (bovine parathyroid calcium receptor) which replicated the effect when introduced to polyvalent cations. Because of this, the ability to clone full-length CaSRs from mammals were performed.
Structure
Each protomer of the receptor has a large, N-terminal extracellular domain that linked to create VFT (Venus flytrap) domain. The receptor has a CR (cysteine-rich) domain that links the VFT to the 7 transmembrane domains of the receptor. The 7 transmembrane domain is followed by a long cytoplasmatic tail. The tail has no structure, but still, it has an important role in trafficking and phosphorylation.
The CaSR is a homodimer receptor. The signal transmission occurs only when the agonist binds to the homodimer of the CaSR. Binding of a single protomer will not lead to |

Biography
Born in Pennsylvania, Pearl wrote hits for Crystal Gayle, Kenny Rogers, Johnny Mathis and Dr. Hook, as well as writing the lyrics and music for the Karen Carpenter song "My Body Keeps Changing My Mind". Her songs were also recorded by Aretha Franklin, Randy Travis and Rascal Flatts.
In 1977, Pearl recorded her first album, Pearl, with her sister Deborah Pearl, on London Records. In 1982, she recorded a second album, Words & Music, this time for RCA Records. It yielded the Top 40 hit "If the Love Fits Wear It", which spent sixteen weeks on the Billboard Hot 100, peaking at number 28 in August 1982. It also peaked at number 7 on the Adult Contemporary chart and at number 25 on the Cashbox music chart. The song also charted on the Canadian Adult Contemporary chart, reaching number 16, and in Ireland, where it peaked at number 23.
Pearl also wrote a hit for Dr. Hook ("Girls Can Get It") and one for Crystal Gayle ("You Never Gave Up on Me"). She wrote and produced jingles for Pepsi, Folgers Coffee, Ford, Gillette and others. Composed in 1984, Pearl's Folgers coffee jingle was transformed into country, gospel, jazz, R&B, folk, Celtic and a cappella versions, and Folgers runs an annual contest to find the best new interpretation.

https://en.wikipedia.org/wiki/Zwiesel%20Kristallglas | Zwiesel Kristallglas AG is a manufacturer of crystal glass located in Zwiesel, Germany.
History
Founding
On 25 November 1872 sheet glass was manufactured for the first time in a new glassworks, whose designer was the Zwiesel carter, Anton Mueller. In 1878 a storage hall, a house and stables were added for the factory manager; in 1883 the factory pub was opened.
Sale
On 7 November 1884, Mueller sold the factory with the buildings and a surface area of altogether 3.045 hectares for 36,000 Goldmarks to the brothers Theodor and Gustav Tasche of Cologne. The Zwieseler Farbenglashütte Gebrüder Tasche, generally only called Tasche Glassworks, was converted into a corporation on 21 June 1898. The share capital of the Zwieseler Farbenglashütten, vorm. Gebrüder Tasche, Aktiengesellschaft amounted to 525,000 marks.
Renaming and expansion
On 1 September 1899, a glass plant in Pirna was acquired for 675,000 marks and the company was renamed the Vereinigte Zwieseler und Pirnaer Farbenglaswerke AG. The share capital was increased to 1,200,000 marks. The Zwieseler plant supplied antique glass, so-called "Pirna Kathedralglas".
The enterprise was constantly extended and equipped with new technical equipment. The years 1914 to 1918 during World War I, as well as the postwar years, brought significant difficulties. In 1924 the production range was extended, as container glass was produced for the first time for drinking glasses.

In 1938 he put forward a method for the classification of chemical reactions based on bond breakage and formation during the reaction. The preparative part of his book, Organisch-Chemische Experimentierkunst, was translated into English and published as Organic Preparations by Interscience Publishers, Inc. in 1946.
His book about German chemistry introduces similar thoughts like there were presented by Philipp Lenard in his Deutsche Physik movement.
Enlisting as a commander of a Volkssturm unit, Conrad Weygand was killed in action on 18 April 1945 in Leipzig against US ground forces during the final battle for the city.

https://en.wikipedia.org/wiki/USS%20Jamestown%20%28PG-55%29 | USS Jamestown (PG-55) was a patrol gunboat and after 13 January 1943 a Jamestown-class motor torpedo boat tender acquired by the U.S. Navy during World War II. Her task in her final classification was to provide a "home base" for torpedo boats in remote parts of the ocean during the war, and to provide them with necessary services, such as fuel, food, and repairs.
Construction
Jamestown was built as Savarona in 1928, by Pusey & Jones Corp., Wilmington, Delaware, for Mrs. Thomas S. Cadwallader of Philadelphia, Pennsylvania. While Mrs. Cadwallader operated her, Savarona was said to be the largest and most luxurious yacht in the world. Colonel William Boyce Thompson purchased the palatial vessel in 1929, and renamed her Alder prior to his daughter donating the vessel to the U.S. Navy.
Yacht acquired by the Navy
Alder was donated to the U.S. Navy at New York on 6 December 1940; converted into a gunboat in the Fletcher Division Shipyard of Bethlehem Shipbuilding Co., Hoboken, New Jersey; renamed Jamestown and designated PG-55; and commissioned at New York Navy Yard 26 May 1941.
World War II operations
Jamestown's first summer in the Navy was devoted to training U.S. Naval Academy midshipmen. She sailed to Annapolis, Maryland, 1 June to embark her first detachment of 100 third-class men and 3 instructors for a 2-week training cruise to Norfolk, Virginia.

https://en.wikipedia.org/wiki/Advanced%20Extremely%20High%20Frequency | Advanced Extremely High Frequency (AEHF) is a constellation of communications satellites operated by the United States Space Force. They are used to relay secure communications for the United States Armed Forces, the British Armed Forces, the Canadian Armed Forces, the Netherlands Armed Forces and the Australian Defence Force. The system consists of six satellites in geostationary orbits. The final satellite was launched on 26 March 2020. AEHF is backward compatible with, and replaces, the older Milstar system and will operate at 44 GHz uplink (extremely high frequency (EHF) band) and 20 GHz downlink (super high frequency (SHF) band). The AEHF system is a joint service communications system that provides survivable, global, secure, protected, and jam-resistant communications for high-priority military ground, sea and air assets.
Overview
AEHF satellites use many narrow spot beams directed towards the Earth to relay communications to and from users. Crosslinks between the satellites allow them to relay communications directly rather than via a ground station. The satellites are designed to provide jam-resistant communications with a low probability of interception. They incorporate frequency-hopping radio technology, as well as phased array antennas that can adapt their radiation patterns in order to block out potential sources of jamming.
AEHF incorporates the existing Milstar low data-rate and medium data-rate signals, providing 75–2400 bit/s and 4.8 kbit/s–1.544 Mbit/s r |
https://en.wikipedia.org/wiki/SWIFT%20J1756.9%E2%88%922508 | SWIFT J1756.9−2508 is a millisecond pulsar with a rotation frequency of 182 Hz (period of 5.5 ms). It was discovered in 2007 by the Swift Gamma-Ray Burst Explorer and found to have a companion with a mass between 0.0067 and 0.030 solar masses. It is thought that the companion is the remnant of a former companion star, now stripped down to a planetary-mass core. The pulsar is accreting mass from this companion, resulting in occasional violent outbursts from the accumulated material on the neutron star.
Planetary system
SWIFT J1756.9-2508's only known planet is notable for its orbital period of less than an hour, about 54 minutes and 43 seconds.

https://en.wikipedia.org/wiki/MUMPS%20%28software%29 | MUMPS (MUltifrontal Massively Parallel sparse direct Solver) is a software application for the solution of large sparse systems of linear algebraic equations on distributed memory parallel computers. It was developed in European project PARASOL (1996–1999) by CERFACS, IRIT-ENSEEIHT and RAL. The software implements the multifrontal method, which is a version of Gaussian elimination for large sparse systems of equations, especially those arising from the finite element method. It is written in Fortran 90 with parallelism by MPI and it uses BLAS and ScaLAPACK kernels for dense matrix computations.
Since 1999, MUMPS has been supported by CERFACS, IRIT-ENSEEIHT, and INRIA.
The importance of MUMPS lies in the fact that it is a supported free implementation of the multifrontal method.

https://en.wikipedia.org/wiki/Bubble%20point | In thermodynamics, the bubble point is the temperature (at a given pressure) where the first bubble of vapor is formed when heating a liquid consisting of two or more components. Given that vapor will probably have a different composition than the liquid, the bubble point (along with the dew point) at different compositions are useful data when designing distillation systems.
For a single component the bubble point and the dew point are the same and are referred to as the boiling point.
Calculating the bubble point

https://en.wikipedia.org/wiki/Gilbert%20cell | In electronics, the Gilbert cell is a type of frequency mixer. It produces output signals proportional to the product of two input signals. Such circuits are widely used for frequency conversion in radio systems. The advantage of this circuit is the output current is an accurate multiplication of the (differential) base currents of both inputs. As a mixer, its balanced operation cancels out many unwanted mixing products, resulting in a "cleaner" output.
It is a generalized case of an early circuit first used by Howard Jones in 1963, invented independently and greatly augmented by Barrie Gilbert in 1967. It is a specific example of "translinear" design, a current-mode approach to analog circuit design. The specific property of this cell is that the differential output current is a precise algebraic product of its two differential analog current inputs.
Function
There is little difference between the Jones cell and the translinear multiplier in this topology. In both forms, two differential amplifier stages are formed by emitter-coupled transistor pairs (Q1/Q4, Q3/Q5) whose outputs are connected (currents summed) with opposite phases. The emitter junctions of these amplifier stages are fed by the collectors of a third differential pair (Q2/Q6). The output currents of Q2/Q6 become emitter currents for the differential amplifiers. Simplified, the output current of an individual transistor is given by ic = gm vbe. Its transconductance gm is (at ) about . Combining these equati |
https://en.wikipedia.org/wiki/Colombian%20Sign%20Language | Colombian Sign Language (, ) is the deaf sign language of Colombia.
Classification
Clark notes that Peruvian, Bolivian, Ecuadorian and Colombian sign languages "have significant lexical similarities to each other" and "contain a certain degree of lexical influence from ASL" as well, at least going by the forms in national dictionaries. Chilean and Argentine share these traits, though to a lesser extent.
Description
The development of the signs have influences of Spanish sign language and American Sign Language. It is reported to have signs in common with Salvadoran Sign Language.
Teaching
There are two sign language schools in Bogotá (the first started in 1929), two in Medellín and one in Cali. Countrywide, three different institutions of support for deaf promotes the learning of the language. The national Committee for the sign language promotes the research in the area, distributes the manual alphabet for spelling and the Grammar Dictionary and supports the organization for sign language teachers. The now defunct national central of telecommunications TELECOM distributed a CD-ROM software for self-learning.
Relevancy
There is a growing interest for learning the sign language between the hearing people. Some schools use sign language in the classroom. Interpreters are provided at important public events, and for college students.

https://en.wikipedia.org/wiki/Vack%C3%A1%C5%99%20oscillator | A Vackář oscillator is a wide range variable frequency oscillator (VFO) which has a near constant output amplitude over its frequency range. It is similar to a Colpitts oscillator or a Clapp oscillator, but those designs do not have a constant output amplitude when tuned.
Invention
In 1949, the Czech engineer Jiří Vackář published a paper on the design of stable variable-frequency oscillators (VFO). The paper discussed many stability issues such as variations with temperature, atmospheric pressure, component aging, and microphonics. For example, Vackář describes making inductors by first heating the wire and then winding the wire on a stable ceramic coil form. The resulting inductor has a temperature coefficient of 6 to 8 parts per million per degree Celsius. Vackář points out that common air variable capacitors have a stability of 2 parts per thousand; to build a VFO with a stability of 50 parts per million requires that the variable capacitor is only 1/40 of the tuning capacity (.002/40 = 50ppm). The stability requirement also implies the variable capacitor may only tune a limited range of 1:1.025. Larger tuning ranges require switching stable fixed capacitors or inductors.
Vackář was interested in high stability designs, so he wanted the highest for his circuits. It is possible to make wide range VFOs with stable output amplitude by heavily damping (loading) the tuned circuit, but that tactic substantially reduces the and the frequency stability.

https://en.wikipedia.org/wiki/Composition%20of%20the%20human%20body | Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water, protein, fats (or lipids), hydroxylapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal human gastrointestinal tract.
Elements
About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life. The remaining elements are trace elements, of which more than a dozen are thought on the basis of good evidence to be necessary for life. All of the mass of the trace elements put together (less than 10 grams for a human body) do not add up to the body mass of magnesium, the least common of the 11 non-trace elements.
Other elements
Not all elements which are found in the human body in trace quantities play a role in life. Some of these elements are thought to be simple common contaminants without function (examples: caesium, titanium), while many others are thought to be active t |
https://en.wikipedia.org/wiki/Protein%20mass%20spectrometry | Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins. Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses. Its applications include the identification of proteins and their post-translational modifications, the elucidation of protein complexes, their subunits and functional interactions, as well as the global measurement of proteins in proteomics. It can also be used to localize proteins to the various organelles, and determine the interactions between different proteins as well as with membrane lipids.
The two primary methods used for the ionization of protein in mass spectrometry are electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI). These ionization techniques are used in conjunction with mass analyzers such as tandem mass spectrometry. In general, the proteins are analyzed either in a "top-down" approach in which proteins are analyzed intact, or a "bottom-up" approach in which protein are first digested into fragments. An intermediate "middle-down" approach in which larger peptide fragments are analyzed may also sometimes be used.
History
The application of mass spectrometry to study proteins became popularized in the 1980s after the development of MALDI and ESI. These ionization techniques have played a significant role in the characterization of p |
https://en.wikipedia.org/wiki/Tutte%E2%80%93Berge%20formula | In the mathematical discipline of graph theory the Tutte–Berge formula is a characterization of the size of a maximum matching in a graph. It is a generalization of Tutte theorem on perfect matchings, and is named after W. T. Tutte (who proved Tutte's theorem) and Claude Berge (who proved its generalization).
Statement
The theorem states that the size of a maximum matching of a graph equals
where counts how many of the connected components of the graph have an odd number of vertices.
Equivalently, the number of unmatched vertices in a maximum matching equals.
Explanation
Intuitively, for any subset of the vertices, the only way to completely cover an odd component of by a matching is for one of the matched edges covering the component to be incident to . If, instead, some odd component had no matched edge connecting it to , then the part of the matching that covered the component would cover its vertices in pairs, but since the component has an odd number of vertices it would necessarily include at least one leftover and unmatched vertex. Therefore, if some choice of has few vertices but its removal creates a large number of odd components, then there will be many unmatched vertices, implying that the matching itself will be small. This reasoning can be made precise by stating that the size of a maximum matching is at most equal to the value given by the Tutte–Berge formula.

https://en.wikipedia.org/wiki/Ion%20cyclotron%20resonance | Ion cyclotron resonance is a phenomenon related to the movement of ions in a magnetic field. It is used for accelerating ions in a cyclotron, and for measuring the masses of an ionized analyte in mass spectrometry, particularly with Fourier transform ion cyclotron resonance mass spectrometers. It can also be used to follow the kinetics of chemical reactions in a dilute gas mixture, provided these involve charged species.
Definition of the resonant frequency
An ion in a static and uniform magnetic field will move in a circle due to the Lorentz force. The angular frequency of this cyclotron motion for a given magnetic field strength B is given by
where z is the number of positive or negative charges of the ion, e is the elementary charge and m is the mass of the ion. An electric excitation signal having a frequency f will therefore resonate with ions having a mass-to-charge ratio m/z given by
The circular motion may be superimposed with a uniform axial motion, resulting in a helix, or with a uniform motion perpendicular to the field (e.g., in the presence of an electrical or gravitational field) resulting in a cycloid.

https://en.wikipedia.org/wiki/Giacinto%20Morera | Giacinto Morera (18 July 1856 – 8 February 1909), was an Italian engineer and mathematician. He is known for Morera's theorem in the theory of functions of a complex variable and for his work in the theory of linear elasticity.
Biography
Life
He was born in Novara on 18 July 1856, the son of Giacomo Morera and Vittoria Unico. According to , his family was a wealthy one, his father being a rich merchant. This occurrence eased him in his studies after the laurea: however, he was an extraordinarily hard worker and he widely used this ability in his researches. After studying in Turin he went to Pavia, Pisa and Leipzig: then he went back to Pavia for a brief period in 1885, and finally he went to Genova in 1886, living here for the next 15 years. While being in Genova he married his fellow-citizen Cesira Faà. From 1901 on to his death he worked in Turin: he died of pneumonia on 8 February 1909.
Education and academic career
He earned in 1878 the laurea in engineering and then, in 1879, the laurea in mathematics, both awarded him from the Politecnico di Torino: According to , the title of his thesis in the mathematical sciences was: "Sul moto di un punto attratto da due centri fissi colla legge di Newton". In Turin he attended the courses held by Enrico d'Ovidio, Angelo Genocchi and particularly the ones held by Francesco Siacci: later in his life, Morera acknowledged Siacci as his mentor in scientific research and life. After graduating, he followed several advanced courses: |

This was their eleventh of fourteen films appearing together. The supporting cast include Gail Patrick, Jack Carson and Sig Ruman.
Plot
Architect Steve Ireland and his wife Susan eagerly look forward to their fourth wedding anniversary, but her mother Mrs. Cooper shows up and puts a damper on their eccentric and jokey plans for the evening; their personal recreation of a Baffin Island Inuit ritual, this year done backwards. She sends Steve to mail her insurance premium, having sprained her foot.
Downstairs he runs into his old girlfriend Isobel Kimble Grayson and learns that she has just moved into the apartment building, one floor below. On the way up, the elevator gets stuck. While they are getting out, Steve is half-strangled and struck several times in the head becoming woozy. Isobel takes him to her apartment to recover where she plies him with numerous strong drinks. Though she is now also married, she makes it clear that she would not mind renewing their relationship, but Steve is hopelessly in love with his wife.
When he returns to his apartment in a disheveled state, he neglects to mention his encounter with Isobel. It becomes very evident however when her shoes are found in his jacket pockets, taken when he helped her up ou |
https://en.wikipedia.org/wiki/Plane%20wave%20expansion%20method | Plane wave expansion method (PWE) refers to a computational technique in electromagnetics to solve the Maxwell's equations by formulating an eigenvalue problem out of the equation. This method is popular among the photonic crystal community as a method of solving for the band structure (dispersion relation) of specific photonic crystal geometries. PWE is traceable to the analytical formulations, and is useful in calculating modal solutions of Maxwell's equations over an inhomogeneous or periodic geometry. It is specifically tuned to solve problems in a time-harmonic forms, with non-dispersive media (a reformulation of the method named Inverse dispersion allows frequency-dependent refractive indices).
Principles
Plane waves are solutions to the homogeneous Helmholtz equation, and form a basis to represent fields in the periodic media. PWE as applied to photonic crystals as described is primarily sourced from Dr. Danner's tutorial.
The electric or magnetic fields are expanded for each field component in terms of the Fourier series components along the reciprocal lattice vector. Similarly, the dielectric permittivity (which is periodic along reciprocal lattice vector for photonic crystals) is also expanded through Fourier series components.

https://en.wikipedia.org/wiki/Functional%20classification | The functional classification of a road is the class or group of roads to which the road belongs. There are three main functional classes as defined by the United States Federal Highway Administration: arterial, collector, and local.
Arterial roads
Arterial roads generally provide the fastest method of travel and typically have low accessibility from neighboring roads. They are usually designed with long-distance travel in mind and are not as common as the other two functional classes of roads. Examples include interstates and highways.
Collector roads
Collector roads are the second most common and are used as a connection between local roads and arterial roads. They provide a balance between access and mobility.
Local roads
Local roads are the most common roads by far, but are also the slowest for travel. They are designed specifically to have high accessibility and to connect to collector and arterial roads, and are typically not used for through traffic. The main function of local roads are to allow for people who live in low density residential to connect to other residential areas or to collector roads.

https://en.wikipedia.org/wiki/6-MeO-THH | 6-MeO-THH, or 6-methoxy-1,2,3,4-tetrahydroharman, is a β-carboline (or more specifically a pinoline) derivative and a structural isomer of tetrahydroharmine (7-MeO-THH). 6-MeO-THH is mentioned in Alexander Shulgin's book TiHKAL (Tryptamines I Have Known and Loved), stating that 6-MeO-THH is very similar to the other carbolines. Limited testing suggests that it possesses mild psychoactive effects at 1.5 mg/kg and is said to be about one-third as potent as 6-methoxyharmalan. It has been isolated from certain plants of the Virola family.
Pharmacology
Very little is known about the psychoactivity of 6-MeO-THH in humans. Studies in rats have shown it to bind to a number of serotonin 5-HT1 receptors and 5-HT2 receptors, dopamine D2 receptors, benzodiazepine receptors, and imidazoline receptors.

https://en.wikipedia.org/wiki/Barnes%20%28name%29 | Barnes is an English surname and rare given name. At the time of the British Census of 1881, the relative frequency of the surname Barnes was highest in Dorset (2.9 times the British average), followed by Wiltshire, Cumberland, Hampshire, Norfolk, Cambridgeshire, Buckinghamshire, Huntingdonshire, Lancashire and Sussex.
There are multiple theories of the origin of the surname; it is variously suggested to be of Anglo-Saxon, Norse, or Irish provenance. According to one etymology, the name is derived from Old English beorn (warrior), which is in turn of Old Norse origin. In another account, it was simply an occupational name for a person who works in a barn, or a topographic name for a person who lives near a barn.

https://en.wikipedia.org/wiki/Trioxsalen | Trioxsalen (trimethylpsoralen (TMP), trioxysalen (INN) or Trisoralen) is a furanocoumarin and a psoralen derivative. It is obtained from several plants, mainly Psoralea corylifolia. Like other psoralens it causes photosensitization of the skin. It is administered either topically or orally in conjunction with UV-A (the least damaging form of ultraviolet light) for phototherapy treatment of vitiligo and hand eczema. After photoactivation it creates interstrand cross-links in DNA, which can cause programmed cell death unless repaired by cellular mechanisms. In research it can be conjugated to dyes for confocal microscopy and used to visualize sites of DNA damage. The compound is also being explored for development of antisense oligonucleotides that can be cross-linked specifically to a mutant mRNA sequence without affecting normal transcripts differing at even a single base pair.
Trioxsalen (abbreviated as TMP) activated by UV-A exposure is commonly used in genetics research as an experimental mutagen. UV/TMP generates small deletions (~1-3 Kbp), but all base transitions and transversions can also be obtained.

"The Problem of Cell 13" is a short story by Jacques Futrelle. It was first published in 1905 and later collected in The Thinking Machine (1907), which was featured in crime writer H. R. F. Keating's list of the 100 best crime and mystery books ever published. Science fiction and mystery author Harlan Ellison recalled that this story was his selection for "Lawrence Block's Best Mysteries of the Century".
Plot summary
Like Futrelle's other short stories, "The Problem of Cell 13" features Augustus S. F. X. Van Dusen as the main character, although most of the story is seen through the perspective of a prison warden. While in a scientific debate with two men, Dr. Charles Ransome and Alfred Fielding, Augustus, "The Thinking Machine", insists that nothing is impossible when the human mind is properly applied. To prove this, he agrees that he will take part in an experiment in which he will be incarcerated in a prison for one week and given the challenge of escaping.
Adaptations
The story was adapted for television by Arthur A. Ross in 1962 as part of the U.S. series Kraft Mystery Theater. The episode starred Claude Dauphin as Van Dusen, and was awarded the 1963 Edgar Award for Best Episode in a TV Series.
"Cell 13", a 1973 adaptation for the British series The Rivals of Sherlock Holmes, featured Douglas Wilmer, famous for his portrayal of Holmes in BBC productions of the sixties, as the Professor.

https://en.wikipedia.org/wiki/NAD%2B%20kinase | {{DISPLAYTITLE:NAD+ kinase}}
NAD+ kinase (EC 2.7.1.23, NADK) is an enzyme that converts nicotinamide adenine dinucleotide (NAD+) into NADP+ through phosphorylating the NAD+ coenzyme. NADP+ is an essential coenzyme that is reduced to NADPH primarily by the pentose phosphate pathway to provide reducing power in biosynthetic processes such as fatty acid biosynthesis and nucleotide synthesis. The structure of the NADK from the archaean Archaeoglobus fulgidus has been determined.
In humans, the genes NADK and MNADK encode NAD+ kinases localized in cytosol and mitochondria, respectively. Similarly, yeast have both cytosolic and mitochondrial isoforms, and the yeast mitochondrial isoform accepts both NAD+ and NADH as substrates for phosphorylation.
Reaction
ATP + NAD+ ADP + NADP+
Mechanism
NADK phosphorylates NAD+ at the 2’ position of the ribose ring that carries the adenine moiety. It is highly selective for its substrates, NAD and ATP, and does not tolerate modifications either to the phosphoryl acceptor, NAD, or the pyridine moiety of the phosphoryl donor, ATP. NADK also uses metal ions to coordinate the ATP in the active site. In vitro studies with various divalent metal ions have shown that zinc and manganese are preferred over magnesium, while copper and nickel are not accepted by the enzyme at all. A proposed mechanism involves the 2' alcohol oxygen acting as a nucleophile to attack the gamma-phosphoryl of ATP, releasing ADP.
Regulation
NADK is highly regulated b |

https://en.wikipedia.org/wiki/Article%20spinning | Article spinning is a writing technique used in search engine optimization (SEO), and other applications, which creates what deceitfully appears to be new content from what already exists. Content spinning works by replacing specific words, phrases, sentences, or even entire paragraphs with any number of alternate versions, in order to provide a slightly different variation with each spin — also known as Rogeting. This process can be completely automated or written manually as many times as needed. Early content produced through automated methods often resulted in articles which were hard or even impossible to read. However, as article-spinning techniques were refined they became more sophisticated, and can now result in readable articles which, upon cursory review, can appear original.
The practice is sometimes considered to fall under the category of spamdexing, a black hat SEO practice, given that no genuinely new content is created. Website authors use article spinning to reduce the similarity ratio of rather redundant pages or pages with minimal or meaningless or uninformative content, and to avoid penalties in the search engine results pages (SERPs) for using duplicate content.
Article spinning is also used in other types of applications, such as message personalization and chatbots.
Regardless of the application, the end result is a proliferation of documents that are all similar but are superficially disguised as being different. The spin-generated documen |
https://en.wikipedia.org/wiki/Articulated%20body%20pose%20estimation | Articulated body pose estimation in computer vision is the study of algorithms and systems that recover the pose of an articulated body, which consists of joints and rigid parts using image-based observations. It is one of the longest-lasting problems in computer vision because of the complexity of the models that relate observation with pose, and because of the variety of situations in which it would be useful.
Description
Perception of human beings in their neighboring environment is an important capability that robots must possess. If a person uses gestures to point to a particular object, then the interacting machine should be able to understand the situation in real world context. Thus pose estimation is an important and challenging problem in computer vision, and many algorithms have been deployed in solving this problem over the last two decades. Many solutions involve training complex models with large data sets.
Pose estimation is a difficult problem and an active subject of research because the human body has 244 degrees of freedom with 230 joints. Although not all movements between joints are evident, the human body is composed of 10 large parts with 20 degrees of freedom. Algorithms must account for large variability introduced by differences in appearance due to clothing, body shape, size, and hairstyles. Additionally, the results may be ambiguous due to partial occlusions from self-articulation, such as a person's hand covering their face, or occlusions from |
https://en.wikipedia.org/wiki/Other%20White | The term Other White, or White Other, is a classification of ethnicity in the United Kingdom used in documents, such as the 2011 UK Census, to describe people who self-identify as white (chiefly European) persons who are not of the English, Welsh, Scottish, Romani or Irish ethnic groupings.
The category does not comprise a single ethnic group but is instead a method of identification for white people who are not represented by other white census categories. This means that the Other White group contains a diverse collection of people not of British, Irish or Romani descent, or with different countries of birth.
In 2011, the Scottish Government introduced the category White Polish to differentiate Polish Britons, and Polish residents, living in Scotland from this broad grouping.
The categorisation was primarily intended to cover people with that have descended or migrated from Continental Europe, with the largest represented ethnic groups being Poles (except in Scotland since 2011), Germans, Romanians, Italians and the French. However, white people from outside of the continent, are also represented in the White Other category.
Along with White British and White Irish, the category does not appear in Northern Ireland, where only one single "White" classification was presented to respondents.
According to the 2021 United Kingdom census, those identifying as Other White in England & Wales enumerated 3,667,997, or 6.2% of the population.

https://en.wikipedia.org/wiki/Classical%20Chinese%20writers | Classical Chinese writers were trained as compilers rather than as originators composing information. These writers in Classical Chinese were trained by memorizing extensive tracts in the classics and histories. Their method of constructing their own work was to extensively cut and paste passages and fragments from these sources. Today this would be called plagiarism. However, these early Chinese writers considered themselves not as creators, but as preservers of the record. The continuing controversy over the meaning of Chinese text is best understood by examining the classical scholar's way of writing. Zhu Xi was a great editor and commentator but his prime aim was moral learning, considered far more important than art or literature. Zhu Xi cemented Confucian moral righteousness into the Chinese methods of evaluation. Joseph Needham has said, Chinese writers made careful note of observable concrete phenomena but they made little use of categorical analysis or the building of logical systems.

https://en.wikipedia.org/wiki/Molecular%20propeller | Molecular propeller is a molecule that can propel fluids when rotated, due to its special shape that is designed in analogy to macroscopic propellers: it has several molecular-scale blades attached at a certain pitch angle around the circumference of a shaft, aligned along the rotational axis.
The molecular propellers designed in the group of Prof. Petr Král from the University of Illinois at Chicago have their blades formed by planar aromatic molecules and the shaft is a carbon nanotube. Molecular dynamics simulations show that these propellers can serve as efficient pumps in the bulk and at the surfaces of liquids. Their pumping efficiency depends on the chemistry of the interface between the blades and the liquid. For example, if the blades are hydrophobic, water molecules do not bind to them, and the propellers can pump them well. If the blades are hydrophilic, water molecules form hydrogen bonds with the atoms in the polar blades. This can largely block the flow of other water molecules around the blades and significantly slow down their pumping.
Driving
Molecular propellers can be rotated by molecular motors that can be driven by chemical, biological, optical and electrical means, or various ratchet-like mechanisms. Nature realizes most biological activities with a large number of highly sophisticated molecular motors, such as myosin, kinesin, and ATP synthase. For example, rotary molecular motors attached to protein-based tails called flagella can propel bacteria. |

https://en.wikipedia.org/wiki/SRD5A2 | The human gene SRD5A2 encodes the 3-oxo-5α-steroid 4-dehydrogenase 2 enzyme, also known as 5α-reductase type 2 (5αR2), one of three isozymes of 5α-reductase.
5αR2 catalyzes the conversion of the male sex hormone testosterone into the more potent androgen, dihydrotestosterone.
5αR2 is a microsomal protein expressed at high levels in androgen-sensitive tissues such as the prostate. The enzyme is active at acidic pH and is sensitive to the 4-azasteroid inhibitor finasteride. Deficiencies in 5αR2 activity of the can lead to a condition known as 5α-reductase 2 deficiency, which is a cause of 46,XY DSD that presents as atypical male genitalia.

https://en.wikipedia.org/wiki/Wu%27s%20method%20of%20characteristic%20set | Wenjun Wu's method is an algorithm for solving multivariate polynomial equations introduced in the late 1970s by the Chinese mathematician Wen-Tsun Wu. This method is based on the mathematical concept of characteristic set introduced in the late 1940s by J.F. Ritt. It is fully independent of the Gröbner basis method, introduced by Bruno Buchberger (1965), even if Gröbner bases may be used to compute characteristic sets.
Wu's method is powerful for mechanical theorem proving in elementary geometry, and provides a complete decision process for certain classes of problem. It has been used in research in his laboratory (KLMM, Key Laboratory of Mathematics Mechanization in Chinese Academy of Science) and around the world. The main trends of research on Wu's method concern systems of polynomial equations of positive dimension and differential algebra where Ritt's results have been made effective. Wu's method has been applied in various scientific fields, like biology, computer vision, robot kinematics and especially automatic proofs in geometry.
Informal description
Wu's method uses polynomial division to solve problems of the form:
where f is a polynomial equation and I is a conjunction of polynomial equations. The algorithm is complete for such problems over the complex domain.
The core idea of the algorithm is that you can divide one polynomial by another to give a remainder. Repeated division results in either the remainder vanishing (in which case the I implies f state |
https://en.wikipedia.org/wiki/Lule%C3%A5%20algorithm | The Luleå algorithm of computer science, designed by , is a technique for storing and searching internet routing tables efficiently. It is named after the Luleå University of Technology, the home institute/university of the technique's authors. The name of the algorithm does not appear in the original paper describing it, but was used in a message from Craig Partridge to the Internet Engineering Task Force describing that paper prior to its publication.
The key task to be performed in internet routing is to match a given IPv4 address (viewed as a sequence of 32 bits) to the longest prefix of the address for which routing information is available. This prefix matching problem may be solved by a trie, but trie structures use a significant amount of space (a node for each bit of each address) and searching them requires traversing a sequence of nodes with length proportional to the number of bits in the address. The Luleå algorithm shortcuts this process by storing only the nodes at three levels of the trie structure, rather than storing the entire trie.
Before building the Luleå trie, the routing table entries need to be preprocessed. Any bigger prefix that overlaps a smaller prefix must be repeatedly split into smaller prefixes, and only the split prefixes which does not overlap the smaller prefix is kept. It is also required that the prefix tree is complete. If there is no routing table entries for the entire address space, it must be completed by adding dummy entries, whi |

It is a research study on the available ancient manuscripts in the Mithila region, called as Panjis, which are genealogical charts of Maithil Brahmin and Kayasthas castes. This study deals with the manuscripts available in respect of Karna Kayasthas.
Overview
The work is based on several manuscripts of Panjis obtained from various panjikars of Darbhanga, Bihar. The Panjis concerned deals with the genealogy of the Karna Kayasthas. The manuscript is written in Tirhuta script (Maithili script) on palm leaves and old paper called as 'Basaha' made out of indigenous material. The work deals with Mulgrams (original village homes) and the transmigration of the Karna Kayasthas to subsequent places of living. The book is important for the geographical and social study of North Bihar of the concerned period. The work also deals with personalities of eminence among the Karna Kayasthas since 12th century. Dr (Prof) Surendra Lal Das along with Panjikars and other eminent Karna kayastha members formed "Akhil Bhartiya Karn kayastha Mahasabha" to protect the original and traditional values of Panji .

https://en.wikipedia.org/wiki/Souders%E2%80%93Brown%20equation | The Souders–Brown equation (named after Mott Souders and George Granger Brown) has been a tool for obtaining the maximum allowable vapor velocity in vapor–liquid separation vessels (variously called flash drums, knockout drums, knockout pots, compressor suction drums and compressor inlet drums). It has also been used for the same purpose in designing trayed fractionating columns, trayed absorption columns and other vapor–liquid-contacting columns.
A vapor–liquid separator drum is a vertical vessel into which a liquid and vapor mixture (or a flashing liquid) is fed and wherein the liquid is separated by gravity, falls to the bottom of the vessel, and is withdrawn. The vapor travels upward at a design velocity which minimizes the entrainment of any liquid droplets in the vapor as it exits the top of the vessel.
Use
The diameter of a vapor–liquid separator drum is dictated by the expected volumetric flow rate of vapor and liquid from the drum. The following sizing methodology is based on the assumption that those flow rates are known.
Use a vertical pressure vessel with a length–diameter ratio of about 3 to 4, and size the vessel to provide about 5 minutes of liquid inventory between the normal liquid level and the bottom of the vessel (with the normal liquid level being somewhat below the feed inlet).
Calculate the maximum allowable vapor velocity in the vessel by using the Souders–Brown equation:
Then the cross-sectional area of the drum can be found from:

https://en.wikipedia.org/wiki/Nandana%20Fort | Nandana Fort or Nandna Fort () was a fort built at strategic location on a hilly range on the eastern flanks of the Salt Range in Punjab. Its ruins, including those of a town and a temple, are present.
History
It was ruled by the Hindu Shahi kings until, in the early 11th century, Mahmud of Ghazni expelled them from Nandana. Al-Biruni carried out his measurements of the circumference of the Earth here.
The Tourism Development Corporation of Punjab (TDCP) was tasked by the Prime Ministers Office to rehabilitate the site with the aim of making it an international tourist destination. Prime Minister Imran Khan had been informed of the decrepit state of the site by his wife's nephew, Shahroze Khan, who had previously heard about the state of the fort from Paul Salopek, a New York Times contributor. In February 2021, the PM and several aides and cabinet members attended an official event celebrating the restoration of the site.
Anandapala, the son of Jayapala of the Hindu Shahi dynasty, had erected the Shiva temple in Nandana.

It was established as a legal entity of public law according to the December 11, 2009 law of Georgia, succeeding the Department of Statistics of the Ministry of Economy and Sustainable Development of Georgia. The head office is located in Tbilisi.
History
The earliest references to the collection of statistics in Georgia date from the 13th century. Materials from population censuses made in the seventeenth and eighteenth centuries in various regions of the country have survived to the present day.
On November 15, 1918 a temporary Statistical Bureau was formed within the Ministry of Agriculture of the Democratic Republic of Georgia. The bureau's functions included development of materials for agricultural census, accounting of the available land and determining of norms for its distribution. On the basis of law enacted by the Constituent Assembly on July 25, 1919, a Republican Statistical Committee was formed within the same ministry. The committee was assigned to manage all types of statistical works of national importance.

https://en.wikipedia.org/wiki/Myristoleic%20acid | Myristoleic acid, or 9-tetradecenoic acid, is an omega-5 fatty acid. It is biosynthesized from myristic acid by the enzyme Stearoyl-CoA desaturase-1, but it is uncommon in nature. One of the major sources of this fatty acid is the seed oil from plants of the family Myristicaceae, comprising up to 30 per cent of the oil in some species. It is a constituent of Serenoa or Saw palmetto, and appears to have activity against LNCaP prostate-cancer cells.

https://en.wikipedia.org/wiki/Patch%20test%20%28finite%20elements%29 | The patch test in the finite element method is a simple indicator of the quality of a finite element, developed by Bruce Irons.
The patch test uses a partial differential equation on a domain consisting from several elements set up so that the exact solution is known and can be reproduced, in principle, with zero error. Typically, in mechanics, the prescribed exact solution consists of displacements that vary as piecewise linear functions in space (called a constant strain solution). The elements pass the patch test if the finite element solution is the same as the exact solution.
It was long conjectured by engineers that passing the patch test is sufficient for the convergence of the finite element, that is, to ensure that the solutions from the finite element method converge to the exact solution of the partial differential equation as the finite element mesh is refined. However, this is not the case, and the patch test is neither sufficient nor necessary for convergence.
A broader definition of patch test (applicable to any numerical method, including and beyond finite elements) is any test problem having an exact solution that can, in principle, be exactly reproduced by the numerical approximation. Therefore, a finite-element simulation that uses linear shape functions has patch tests for which the exact solution must be piecewise linear, while higher-order finite elements have correspondingly higher-order patch tests.

https://en.wikipedia.org/wiki/Diffusion-controlled%20reaction | Diffusion-controlled (or diffusion-limited) reactions are reactions in which the reaction rate is equal to the rate of transport of the reactants through the reaction medium (usually a solution). The process of chemical reaction can be considered as involving the diffusion of reactants until they encounter each other in the right stoichiometry and form an activated complex which can form the product species. The observed rate of chemical reactions is, generally speaking, the rate of the slowest or "rate determining" step. In diffusion controlled reactions the formation of products from the activated complex is much faster than the diffusion of reactants and thus the rate is governed by collision frequency.
Diffusion control is rare in the gas phase, where rates of diffusion of molecules are generally very high. Diffusion control is more likely in solution where diffusion of reactants is slower due to the greater number of collisions with solvent molecules. Reactions where the activated complex forms easily and the products form rapidly are most likely to be limited by diffusion control. Examples are those involving catalysis and enzymatic reactions. Heterogeneous reactions where reactants are in different phases are also candidates for diffusion control.
One classical test for diffusion control of a heterogeneous reaction is to observe whether the rate of reaction is affected by stirring or agitation; if so then the reaction is almost certainly diffusion controlled under th |
https://en.wikipedia.org/wiki/Postmodern%20social%20construction%20of%20nature | The postmodern social construction of nature is a theorem or speculation of postmodernist continental philosophy that poses an alternative critique of previous mainstream, Promethean discourse about environmental sustainability and ecopolitics.
Position
Whereas traditional criticisms of environmentalism come from the more conservative "right" of politics, leftist critiques of nature pioneered by postmodernist constructionism highlight the need to recognise "the other". The implicit assumption made by theorists like Wapner refer to it as a new "response to ecocriticism [which] would require critics to acknowledge the ways in which they themselves silence nature and then to respect the sheer otherness of the non-human world."
Criticism
Critics argue that, by capturing the nonhuman world within its own conceptual domain, postmodern exerts precisely the urge toward mastery that it criticizes in modernity. Thus, postmodern cultural criticism deepens the modernist urge toward mastery by eliminating the ontological weight of the nonhuman world. "What else could it mean to assert that there is no such thing as nature?". The issue becomes an existentialist query about whether nature can exist in a humanist critique, and whether we can discern the "others'" views in relation to our actions on their behalf. This is referred to as the Wapner Paradox.

https://en.wikipedia.org/wiki/LU%20reduction | LU reduction is an algorithm related to LU decomposition. This term is usually used in the context of super computing and highly parallel computing. In this context it is used as a benchmarking algorithm, i.e. to provide a comparative measurement of speed for different computers. LU reduction is a special parallelized version of an LU decomposition algorithm, an example can be found in (Guitart 2001). The parallelized version usually distributes the work for a matrix row to a single processor and synchronizes the result with the whole matrix (Escribano 2000).

https://en.wikipedia.org/wiki/Triple%20M%20Sydney | Triple M Sydney (callsign 2MMM) is a radio station broadcasting in Sydney, Australia. Triple M Sydney is part of Southern Cross Austereo's Triple M network and broadcasts on the 104.9 MHz frequency.
History
The Early Days
Triple M commenced broadcasting on 2 August 1980. Together with then rival station 2Day FM, it was one of the first two commercial FM radio stations in Sydney. The Government-owned Triple J began broadcasting on the FM band just one day earlier.
The station has always been primarily a rock music station. In the 80's, Triple M was one of the highest-rating radio stations in Sydney, spearheaded by its breakfast show presented by Doug Mulray and featuring the writing of and occasional appearances by Andrew Denton. From 1988 until the early nineties, Club Veg with Mal Lees and Vic Davies hosted the Night show before moving to Perth to host the breakfast show at 96FM/Triple M.
For all of this period and into the 1990s, Triple M's promotional campaign featured the character "Dr Dan", a guitar-playing satyr with wings, and a theme song that was an extended reworking of the Mike Batt track "Introduction (The Journey of a Fool)", from his 1979 album Tarot Suite.
1990s to Early 2000s
After the Departure of Doug Mulray at breakfast, 2MMM tried a variety of breakfast show hosts, including Rob Duckworth and Sammy Power, and the Richard Stubbs Breakfast Show (broadcast from 3MMM in Melbourne). It was not until the late 1990s when Andrew Denton, a previous contribut |
https://en.wikipedia.org/wiki/Resistive%20ballooning%20mode | The resistive ballooning mode (RBM) is an instability occurring in magnetized plasmas, particularly in magnetic confinement devices such as tokamaks, when the pressure gradient is opposite to the effective gravity created by a magnetic field.
Linear growth rate
The linear growth rate of the RBM instability is given as
where is the pressure gradient is the effective gravity produced by a non-homogeneous magnetic field, R0 is the major radius of the device, Lp is a characteristic length of the pressure gradient, and cs is the plasma sound speed.
Similarity with the Rayleigh–Taylor instability
The RBM instability is similar to the Rayleigh–Taylor instability (RT), with Earth gravity replaced by the effective gravity , except that for the RT instability, acts on the mass density of the fluid, whereas for the RBM instability, acts on the pressure of the plasma.

https://en.wikipedia.org/wiki/Yizhi%20Jane%20Tao | Yizhi Jane Tao is a Chinese biochemist, structural biologist, and professor of biochemistry and cell biology at Rice University in Houston, Texas. Professor Tao led a team of researchers to be the first to map the structure of the influenza A virus nucleoprotein to an atomic level, a feat which circulated widely in the popular press. She was named among the top ten most influential Chinese of 2006 by a consortium of China's leading media outlets including Phoenix Satellite Television, China News Service, Asia Newsweek, and World Journal.
All negative-sense RNA viruses encode a nucleoprotein that surrounds the virus and allows for replication. Tao discovered that the nucleoprotein for influenza A has a distinctive loop that is necessary for the viral genome to be organized into its double-helix hairpin structure. Tao then compared the amino acid sequences of different influenza viruses and found that the nucleoprotein loop she identified is conserved among influenza viruses. Since then, Tao has also solved the structure of a capsid protein coat for a double-stranded fungal RNA virus.
Education
Born in China, Yizhi Jane Tao received a B.Sc. degree in biology from Peking University in Beijing, China in 1992. She later received her Ph.D. in biological sciences from Purdue University while studying bacteriophages under the German-American biophysicist Michael Rossmann, whose lab uncovered a 3D viral structure. She completed a postdoctoral fellowship under Stephen C. Harrison a |
https://en.wikipedia.org/wiki/Architectural%20design%20optimization | Architectural design optimization (ADO) is a subfield of engineering that uses optimization methods to study, aid, and solve architectural design problems, such as optimal floorplan layout design, optimal circulation paths between rooms, sustainability and the like. ADO can be achieved through retrofitting, or it can be incorporated within the initial construction a building. Methods of ADO might include the use of metaheuristic, direct search or model-based optimisation. It could also be a more rudimentary process involving identification of a perceived or existing problem with a buildings design in the concept design phase.
Evolution of digital ADO
The origins of digital based methods of ADO can be attributed to the early days of Computer-Aided Design (CAD), a type of software which enabled architects to create, modify and optimise their drafts freely within a digital environment. Although CAD was invented in the early 1960s, with Ivan Sutherland's Sketchpad, its applications predominated the aerospace and automotive industries. It was only until the 1970s that it became of novel use to architects, and only in the 90s did it become widespread within the industry. Programs such as AutoCAD, Rhinoceros and Revit have since assisted architects in the creation of more accurate, more extensively optimised designs by relying on computational power to determine efficient variables in areas of daylighting, energy consumption, circulation and the like.
