New CCD photometry of NGC 6366 has lead to the discovery of some variable stars. Two possible Anomalous Cepheids (or Pop II Cepheids), three long period variables, one SX Phe and one eclipsing binary have been found. Also a list of 10 candidate variables is reported. The light curve of the RRab star, V1, has been decomposed into its Fourier harmonics, and the Fourier parameters were used to estimate the star's metallicity and distance; [Fe/H] = -0.87 +- 0.14 and d = 3.2 +- 0.1 kpc. It is argued that V1 may not be a member of the cluster but rather a more distant object. If this is so, an upper limit for the distance to the cluster of 2.8 +- 0.1 kpc can be estimated. The P-L relationship for SX Phe stars and the identified modes in the newly discovered SX Phe variable, V6, allow yet another independent determination of the distance to the cluster of d = 2.7 \+- 0.1 kpc. The M_V - {\rm [Fe/H]} relationship for RR Lyrae stars is addressed and the case of V1 is discussed.
Generating a digital twin of any complex system requires modeling and computational approaches that are efficient, accurate, and modular. Traditional reduced order modeling techniques are targeted at only the first two but the novel non-intrusive approach presented in this study is an attempt at taking all three into account effectively compared to their traditional counterparts. Based on dimensionality reduction using proper orthogonal decomposition (POD), we introduce a long short-term memory (LSTM) neural network architecture together with a principal interval decomposition (PID) framework as an enabler to account for localized modal deformation, which is a key element in accurate reduced order modeling of convective flows. Our applications for convection dominated systems governed by Burgers, Navier-Stokes, and Boussinesq equations demonstrate that the proposed approach yields significantly more accurate predictions than the POD-Galerkin method, and could be a key enabler towards near real-time predictions of unsteady flows.
This is obviously an attempt to misdirect satire targeting the status quo and waste our creativity giving "trolls" more attention than they deserve. Worse, it's a way of dividing comm enters against other comm enters. The humorous antics of Yippies back in the 60's and 70's was one of the most effective techniques in exposing the corruption of government, stopping the Vietnam War, revolutionizing the social system, and liberating people everywhere from repressive elitists. A government sanctioned humor program sounds like an oxymoron. The first thing fascists and authoritarians want to get rid of is humor and satire. Moreover, some folks might have noticed since 9/11 newspapers have cancelled their regular humor columns, stopped publishing satire pieces, cancelled their comments pages, and discouraged humorous posts.
If someone has had surgery to alter their gender, then I think its fine that they use the washroom of their new gender. But a person with a 5 o'clock shadow sporting a twig and berries walking in a woman's washroom or pool locker room because they feel like a woman is patently ridiculous.
but I really like the quality of the small doors I've ordered and installed two of these doors. I can't speak for the large sizes, as I've gotten the small doors for my cats, but I really like the quality of the small doors. The installation isn't too difficult if you're good with tools. You will need a jigsaw and drill with 3/8" drill bit to cut a hole in your door. The directions that come with the door are very clear and helpful. I would advise using caulk around the perimeter of the pet door if you're concerned about air leakage. Be careful with the plastic screws that hold the frame pieces together as they are pretty flimsy and can strip out easily. They provide a couple extra screws in case you mess one or two up.
We propose a mixture-of-experts approach for unsupervised domain adaptation from multiple sources. The key idea is to explicitly capture the relationship between a target example and different source domains. This relationship, expressed by a point-to-set metric, determines how to combine predictors trained on various domains. The metric is learned in an unsupervised fashion using meta-training. Experimental results on sentiment analysis and part-of-speech tagging demonstrate that our approach consistently outperforms multiple baselines and can robustly handle negative transfer.
Interest in the research areas related to meme propagation and generation has been increasing rapidly in the last couple of years. Meme datasets available online are either specific to a context or contain no class information. Here, we prepare a large-scale dataset of memes with captions and class labels. The dataset consists of 1.1 million meme captions from 128 classes. We also provide reasoning for the existence of broad categories, called "themes" across the meme dataset; each theme consists of multiple meme classes. Our generation system uses a trained state-of-the-art transformer-based model for caption generation by employing an encoder-decoder architecture. We develop a web interface, called Memeify for users to generate memes of their choice, and explain in detail, the working of individual components of the system. We also perform a qualitative evaluation of the generated memes by conducting a user study. A link to the demonstration of the Memeify system is https://youtu.be/P_Tfs0X-czs.
Harvey Schacter is slipping a bit. Over 5 hours after this latest piece hit the on-line, and I'm posting the first comment. Maybe the ONLY comment. Some unsolicited advice: Harvey! Listen up! You may not get another chance at G&M! You have to think about instant hooks in the headline. Anything that features the word "think" won't qualify. (In fact, that goes for the subject matter, too.) Last headline was a real winner: "The six types of mean men you meet at work." Hot-button material for sure. To prove it: over 80 posts within a day (even acknowledging the usually multiple posts from "Victimitis.") Write something that posters can poke fun at--or each other. Lots of reactions to "Mean" were "funny." Not too many laughs here. But do try again. Remember, gender sells.
Backs come off too easy. The back of these come off so easy. The back with the battery are constantly falling off. I’m going to have to stop using them because I have a toddler and a dog and I can’t risk them finding a loose battery all over the house.
Let me say from the outset I'm not a particular fan of this kind of film, but Nightbreed holds a certain fascination for me with a message about perspective.<br /><br />Back in the old days, the folks who inhabit Midian would have been called Zombies, the undead. And according to what Clive Barker has given us certain members of human kind, in this Craig Sheffer are born with the potential to become part of that world.<br /><br />Psychiatrist David Cronenberg at first looking like the mild mannered professional has taken unto himself a fanatical mission to rid the world of the Nightbreed. He tricks the police into killing Sheffer, but Sheffer goes to a graveyard named Midian cemetery where the Nightbreed congregate and live underground. <br /><br />Sheffer has also left a girl friend, Anne Bobby, who still has feelings for him even after he's been killed and is now one of the undead. She tries in her own small way to be a bridge to humankind. <br /><br />Clive Barker's creatures are a pretty gruesome looking lot and are not particularly fond of humans. But it's plain to see that if humans left them alone, the Nightbreed in turn not bother with them.<br /><br />Your sympathies are definitely with the Nightbreed especially after seeing a fanatic like Cronenberg and redneck police chief Charles Haid in action.<br /><br />Clive Barker's been an out gay man for some time now and some have suggested to me that the Nightbreed is a metaphor for gay people. I can see where that would come in, especially since there are a whole lot of people who don't even think of gays as anything human because they're taught that way.<br /><br />Granted Nightbreed is pretty bloody with a lot of gratuitous violence, but it also does make you think and I do like the way Clive Barker does turn traditional theology on its head and makes Craig Sheffer a kind of messiah for the Nightbreed creatures.
In this work, we show that a class of metric-affine gravities can be reduced to a Riemann-Cartan one. The reduction is based on the cancelation of the nonmetricity against the symmetric components of the spin connection. A heuristic proof, in the Einstein-Cartan formalism, is performed in the special case of diagonal unitary tangent metric tensor. The result is that the nonmetric degrees of freedom decouple from the geometry. Thus, from the point of view of isometries on the tangent manifold, the equivalence might be viewed as an isometry transition from the affine group to the Lorentz group, $A(d,\mathbb{R})\longmapsto SO(d)$. Furthermore, in this transition, depending on the form of the starting action, the nonmetricity degrees might present a dynamical matter field character, with no geometric interpretation in the Riemann-Cartan geometry.
We review some facts about the representation theory of the Hecke algebra. We adapt for the Hecke algebra case the approach of Okounkov and Vershik which was developed for the representation theory of symmetric groups. We justify an explicit construction of the idempotents in the Hecke algebra in terms of Jucys-Murphy elements. Ocneanu's traces for these idempotents (which can be interpreted as q-dimensions of corresponding irreducible representations of quantum linear groups) are presented.
The light CP even Higgs boson mass, Mh, is calculated to three-loop accuracy within the Minimal Supersymmetric Standard Model (MSSM). The result is expressed in terms of DRbar parameters and implemented in the computer program H3m. The calculation is based on the proper approximations and their combination in various regions of the parameter space. The three-loop effects to Mh are typically of the order of a few hundred MeV and opposite in sign to the two-loop corrections. The remaining theory uncertainty due to higher order perturbative corrections is estimated to be less than 1 GeV.
We prove the locally differentiable rigidity of generic partially hyperbolic abelian algebraic high-rank actions on compact homogeneous spaces obtained from split symplectic Lie groups. We also gave a non-generic action rigidity example on compact homogeneous spaces obtained from SL(2n,R) or SL(2n,C). The conclusions are based on geometric Katok-Damjanovic way and progress towards computations of the generating relations in these groups.
And again, I find myself in the minority.<br /><br />I didn't like this one. This is the ONLY Varney work I haven't embraced, including Knowhutimean. Slam Dunk Ernest rates the credit for being the worst of the line, but this is a clear competitor for that dubious title.<br /><br />This work is too rough, and too base to be lovable. Lovability was one of Ernest's key components, and this element was completely lost herein. Unfortunately, most think this is the best of the line, but if you loved the essence of what made Ernest, Ernest, you will realize to what I refer about fifteen minutes into this work. It was too blatantly base to be fun.<br /><br />It rates a 3.5/10 from...<br /><br />the Fiend :.
Disk galaxies can exchange angular momentum and baryons with their host dark matter (DM) halos. These halos possess internal spin, `lambda', which is insignificant rotationally but does affect interactions between the baryonic and DM components. While statistics of prograde and retrograde spinning halos in galaxies is not available at present, the existence of such halos is important for galaxy evolution. In the previous works, we analyzed dynamical and secular evolution of stellar bars in prograde spinning halos and the DM response to the bar perturbation, and found that it is modified by the resonant interactions between the bar and the DM halo orbits. In the present work, we follow the evolution of stellar bars in retrograde halos. We find, that this evolution differs substantially from evolution in rigid unresponsive halos, discussed in the literature. First, we confirm that the bar instability is delayed progressively along the retrograde `lambda' sequence. Second, the bar evolution in the retrograde halos differs also from that in the prograde halos, in that the bars continue to grow substantially over the simulation time of 10 Gyr. The DM response is also substantially weaker compared to this response in the prograde halos. Third, using orbital spectral analysis of the DM orbital structure, we find a phenomenon we call the orbit reversal --- when retrograde DM orbits interact with the stellar bar, reverse their streaming and precession, and become prograde. This process dominates the inner halo region adjacent to the bar and allows these orbits to be trapped by the bar, thus increasing efficiency of angular momentum transfer by the Inner Lindblad Resonance. We demonstrate this reversal process explicitly in a number of examples.
We address the problem of graph classification based only on structural information. Inspired by natural language processing techniques (NLP), our model sequentially embeds information to estimate class membership probabilities. Besides, we experiment with NLP-like variational regularization techniques, making the model predict the next node in the sequence as it reads it. We experimentally show that our model achieves state-of-the-art classification results on several standard molecular datasets. Finally, we perform a qualitative analysis and give some insights on whether the node prediction helps the model better classify graphs.
When the members of the USCCB suddenly jolted their awareness into our current unpleasant Trump reality, my first thought was how similar their 'dismay' and 'disappointment' etc. was to Captain Renault in Casablanca: I'm shocked, shocked to find that gambling is going on in here! Trump is now what he has always been. Some voted for him in spite of it... and some voted for him because of it.... It appears that our prelates are not just trying to climb out of bed with their messy friend... they are hoping to sneak out and then claim to be on the side of justice and human dignity. Here is a long list of what their candidate has done and undone... They own it. https://www.washingtonpost.com/news/politics/wp/2017/08/24/what-trump-has-undone/
The adult sex ratio (ASR) is defined as the number of fertile males divided by the number of fertile females in a population. We build an ODE model with minimal age structure, in which males compete for paternities using either a multiple-mating or searching-then-guarding strategy, to investigate the value of ASR as an index for predicting which strategy males will adopt, with a focus in our investigation on the differences of strategy choice between chimpanzees Pan troglodytes and human hunter-gatherers Homo sapiens. Parameters in the model characterise aspects of life history and behaviour, and determine both dominant strategy and the ASR when the population is at or near equilibrium. Sensitivity analysis on the model parameters informs us that ASR is strongly influenced by parameters characterising life history, while dominant strategy is affected most strongly by the effectiveness of guarding (average length of time a guarded pair persists, and resistance to paternity theft) and moderately by some life history traits. For fixed effectiveness of guarding and other parameters, dominant strategy tends to change from multiple mating to guarding along a curve that aligns well with a contour of constant ASR, under variation of parameters such as longevity and age female fertility ends. This confirms the hypothesis that ASR may be a useful index for predicting the optimal male mating strategy, provided we have some limited information about ecology and behaviour.
A numerical algorithm for explicitly computing the spectrum of the Laplace-Beltrami operator on Calabi-Yau threefolds is presented. The requisite Ricci-flat metrics are calculated using a method introduced in previous papers. To illustrate our algorithm, the eigenvalues and eigenfunctions of the Laplacian are computed numerically on two different quintic hypersurfaces, some Z_5 x Z_5 quotients of quintics, and the Calabi-Yau threefold with Z_3 x Z_3 fundamental group of the heterotic standard model. The multiplicities of the eigenvalues are explained in detail in terms of the irreducible representations of the finite isometry groups of the threefolds.
We show that a perfect obstruction theory for a $\mathbb{G}_\text{m}$-gerbe determines a semi-perfect obstruction theory for its base, which is perfect if the gerbe is quasi-compact and affine-pointed. These results streamline the construction of a semi-perfect obstruction theory for the base, and allow us to relate virtual classes of the gerbe and its base.
We establish a 1:1 correspondence between Poisson-Lie group actions on integrable Poisson manifolds and twisted multiplicative hamiltonian actions on source 1-connected symplectic groupoids. For an action of a Poisson-Lie group $G$ on a Poisson manifold $M$, we find an explicit description of the lifted hamiltonian action on the symplectic groupoid $\Sigma(M)$. We give applications of these results to the integration of Poisson quotients $M/G$, Lu-Weinstein quotients $\mu^{-1}(e)/G$ and Poisson homogeneous spaces $G/H$.
We report on the HST detection of the Lyman-continuum (LyC) radiation emitted by a galaxy at redshift z=3.794, dubbed Ion1 (Vanzella et al. 2012). The LyC from Ion1 is detected at rest-frame wavelength 820$\sim$890 \AA with HST WFC3/UVIS in the F410M band ($m_{410}=27.60\pm0.36$ magnitude (AB), peak SNR = 4.17 in a circular aperture with radius r = 0.12'') and at 700$\sim$830 \AA with the VLT/VIMOS in the U-band ($m_U = 27.84\pm0.19$ magnitude (AB), peak SNR = 6.7 with a r = 0.6'' aperture). A 20-hr VLT/VIMOS spectrum shows low- and high-ionization interstellar metal absorption lines, the P-Cygni profile of CIV and Ly$\alpha$ in absorption. The latter spectral feature differs from what observed in known LyC emitters, which show strong Ly$\alpha$ emission. An HST far-UV color map reveals that the LyC emission escapes from a region of the galaxy that is bluer than the rest, presumably because of lower dust obscuration. The F410M image shows that the centroid of the LyC emission is offset from the centroid of the non-ionizing UV emission by 0.12''$\pm$0.03'', corresponding to 0.85$\pm$0.21 kpc (physical), and that its morphology is likely moderately resolved. These morphological characteristics favor a scenario where the LyC photons produced by massive stars escape from low HI column-density "cavities" in the ISM, possibly carved by stellar winds and/or supernova. We also collect the VIMOS U-band images of a sample of 107 Lyman-break galaxies with spectroscopic redshifts at $3.40<z<3.95$, i.e. sampling the LyC, and stack them with inverse-variance weights. No LyC emission is detected in the stacked image, resulting in a 32.5 magnitude (AB) flux limit (1$\sigma$) and an upper limit of absolute LyC escape fraction $f_{esc}^{abs} < 0.63\%$. LyC emitters like Ion1 are very likely at the bright-end of the LyC luminosity function.
Displacement and velocity memory effects in the exact, vacuum, plane gravitational wave line element have been studied recently by looking at the behaviour of pairs of geodesics or via geodesic deviation. Instead, one may investigate the evolution of geodesic congruences. In our work here, we obtain the evolution of the kinematic variables which characterise timelike geodesic congruences, using chosen pulse profiles (square and sech-squared) in the exact, plane gravitational wave line element. We also analyse the behaviour of geodesic congruences in possible physical scenarios describable using derivatives (first, second and third) of one of the chosen pulses. Beginning with a discussion on the generic behaviour of such congruences and consequences thereof, we find exact analytical expressions for shear and expansion with the two chosen pulse profiles. Qualitatively similar numerical results are noted when various derivatives of the sech-squared pulse are used. We conclude that for geodesic congruences, a growth (or decay) of shear causes focusing of an initially parallel congruence, after the departure of the pulse. A correlation between the `focusing time (or $u$ value, $u$ being the affine parameter)' and the amplitude of the pulse (or its derivatives) is found. Such features distinctly suggest a memory effect, named in recent literature as ${\cal B}$ memory.
Breast cancer mortality remains unacceptably high, indicating a need for safer and more effective therapeutic agents. Disulfide bond Disrupting Agents (DDAs) were previously identified as a novel class of anticancer compounds that selectively kill cancers that overexpress the Epidermal Growth Factor Receptor (EGFR) or its family member HER2. DDAs kill EGFR+ and HER2+ cancer cells via the parallel downregulation of EGFR, HER2, and HER3 and activation/oligomerization of Death Receptors 4 and 5 (DR4/5). However, the mechanisms by which DDAs mediate these effects are unknown. Affinity purification analyses employing biotinylated-DDAs reveal that the Protein Disulfide Isomerase (PDI) family members AGR2, PDIA1, and ERp44 are DDA target proteins. Further analyses demonstrate that shRNA-mediated knockdown of AGR2 and ERp44, or expression of ERp44 mutants, enhance basal and DDA-induced DR5 oligomerization. DDA treatment of breast cancer cells disrupts PDIA1 and ERp44 mixed disulfide bonds with their client proteins. Together, the results herein reveal DDAs as the first small molecule, active site inhibitors of AGR2 and ERp44, and demonstrate roles for AGR2 and ERp44 in regulating the activity, stability, and localization of DR4 and DR5, and activation of Caspase 8.
We do not know much of what going on there. There is untold history that must be learned in that region. WW11 started because of the history of war in the previous wars, claim and counter claim. If you look at the history book this part of the world have not really seen peace for too long. Human being carry with them the past and its a bloody past. You can go back to the Roman Empire, to the division of the east and west. There is so much bloody history. We ought not to take side in this war again till we understand what up this time. It is a European affair and Canada have involved itself twice already. If its another one of those Juggling of empires, a game of thrones by Europeans, Russian, England and American then we ought to keep out of it but lets be honest...we have to be prepared this time...for the worst case scenario.
Carton arrived on time but with several parts discrepancies. Carton visibly crushed & damaged but still secured contents. Comparing parts w/ packing list revealed missing assembly screw and protective plastic plug and an excess of washers & nuts. E-mailed JB Tools with problem & complete details. Response was that they didn't recognize manufacturer's name and wanted a photo of the carton which had been discarded??? Resolved assembly by obtaining screws at hardware store which needed slight modification. Still missing plastic protective plug....but at least support can be used. No help from JB !
Activity recognition and, more generally, behavior inference tasks are gaining a lot of interest. Much of it is work in the context of human behavior. New available tracking technologies for wild animals are generating datasets that indirectly may provide information about animal behavior. In this work, we propose a method for classifying these data into behavioral annotation, particularly collective behavior of a social group. Our method is based on sequence analysis with a direct encoding of the interactions of a group of wild animals. We evaluate our approach on a real world dataset, showing significant accuracy improvements over baseline methods.
Gosh, the race bots are out in full force today. This comment is worth repeating. Please stop being reflexively defensive when someone points out white privilege/racism; same suggestion goes for men who reflexively deny the existence of sexism. Please stop reflexively adding ‘all’ in front of ‘men’ or ‘white people’ in these contexts; sensible people know that not all white people are racist, and not all men are sexist. Nonetheless, you are either part of the problem or part of the solution. What do you do to make (systemic) racism uncool..or do you just practice racial colour-blindness?
Sparky Well I’ll give it 2 star it did work for awhile. Had my inverter for about 9 months. Went to charge up some battery in my company truck for my battery powered tools well lucky I had just started pulling off when the inverter started shooting sparks out of the fan. It did work great before that so I don’t know. Maybe I had to much of a load on it.
Recent studies show that a maximally entangled Schwinger pair creates a nontraversable Einstein-Rosen~(ER) bridge (wormhole) in the gravitational theory, which bridges causally not connected parts of the AdS spacetime~[PRL 111, 211603 and 211602]. Same authors raise the possibility of a general correspondence between a weaker entanglement and curvature. Here, we provide some clues for such a generalized relation. First, we show that (i) entanglement and (ii) violation of Kramers-Kronig~(KK) relations appear at the same critical parameters for a standard two-mode (squeezing) entanglement interaction. We also include the dampings. Second, we bring a study into attention: Presence of a spacetime-curvature in vacuum polarization, electron-positron Schwinger pairs, makes QED also violate the KK relations without violating the causality. Then, we discuss that these findings are possible to provide new clues for a generalized relation between entanglement and spacetime-curvature. Such an interpretation may also save violation of KK relations from implying the violation of the causality.
In the geometric version of the Langlands correspondence, irregular singular point connections play the role of Galois representations with wild ramification. In this paper, we develop a geometric theory of fundamental strata to study irregular singular connections on the projective line. Fundamental strata were originally used to classify cuspidal representations of the general linear group over a local field. In the geometric setting, fundamental strata play the role of the leading term of a connection. We introduce the concept of a regular stratum, which allows us to generalize the condition that a connection has regular semisimple leading term to connections with non-integer slope. Finally, we construct a symplectic moduli space of meromorphic connections on the projective line that contain a regular stratum at each singular point.
This work utilizes data-driven methods to morph a series of time-resolved experimental OH-PLIF images into corresponding three-component planar PIV fields in the closed domain of a premixed swirl combustor. The task is carried out with a fully convolutional network, which is a type of convolutional neural network (CNN) used in many applications in machine learning, alongside an existing experimental dataset which consists of simultaneous OH-PLIF and PIV measurements in both attached and detached flame regimes. Two types of models are compared: 1) a global CNN which is trained using images from the entire domain, and 2) a set of local CNNs, which are trained only on individual sections of the domain. The locally trained models show improvement in creating mappings in the detached regime over the global models. A comparison between model performance in attached and detached regimes shows that the CNNs are much more accurate across the board in creating velocity fields for attached flames. Inclusion of time history in the PLIF input resulted in small noticeable improvement on average, which could imply a greater physical role of instantaneous spatial correlations in the decoding process over temporal dependencies from the perspective of the CNN. Additionally, the performance of local models trained to produce mappings in one section of the domain is tested on other, unexplored sections of the domain. Interestingly, local CNN performance on unseen domain regions revealed the models' ability to utilize symmetry and antisymmetry in the velocity field. Ultimately, this work shows the powerful ability of the CNN to decode the three-dimensional PIV fields from input OH-PLIF images, providing a potential groundwork for a very useful tool for experimental configurations in which accessibility of forms of simultaneous measurements are limited.
Not what I expected. The product was no where near what I was expecting. First of all it was used not new. That back plastic side had a bunch of lint and small dirt spots in. You can see shades of brown in the front cover. Moreover the leather smelled like BO.
Operator-valued frame ($G$-frame), as a generalization of frame is introduced by Kaftal, Larson, and Zhang in \textit{Trans. Amer. Math. Soc.}, 361(12):6349-6385, 2009 and by Sun in \textit{J. Math. Anal. Appl.}, 322(1):437-452, 2006. It has been further extended in the paper arXiv:1810.01629 [math.OA] 3 October 2018, so as to have a rich theory on operator-valued frames for Hilbert spaces as well as for Banach spaces. The continuous version has been studied in this paper when the indexing set is a measure space. We study duality, similarity, orthogonality and stability of this extension. Several characterizations are given including a notable characterization when the measure space is a locally compact group. Variation formula, dimension formula and trace formula are derived when the Hilbert space is finite dimensional.
The other viewpoint illustrated by the rapporteur' s initial statement and shared by a number of members is to promote regulations and codes of conduct which are needed in order to establish among insurers ways of organising costs on a mutual basis providing everybody with guaranteed access to high-quality care and to counter the risk of discriminatory practices developing together with risk and client selection.
Wait. Lemme get this right, Justin. Thanks to you, I can face sanctions and fines if I inadvertently or willfully reject someone's request to use their choice of personal pronoun. If I demonstrate a dislike for anything Islam or Muslim, I face repercussions under M-103. and yet it isn't the government's job to tell what women should wear, yet it is apparently their job to tell us what and what not to say or think. Makes sense....
"Random Color" means mostly drab colors. One pair was an adult size. ??? Two browns, two grays, one navy blue, one orange, and one pink in a gigantic size. My girls wear little kid size 13 shoes, and even the smaller size pictured here was too big, but we probably would have kept anyway because the quality felt nice, and the grippy spots are really grippy. But the colors were disappointing and the one giant pair wasn't useful.
Let $\mathscr T$ be a $2$-Calabi--Yau triangulated category, $T$ a cluster tilting object with endomorphism algebra $\Gamma$. Consider the functor $\mathscr T( T,- ) : \mathscr T \rightarrow \mod \Gamma$. It induces a bijection from the isomorphism classes of cluster tilting objects to the isomorphism classes of support $\tau$-tilting pairs. This is due to Adachi, Iyama, and Reiten. The notion of $( d+2 )$-angulated categories is a higher analogue of triangulated categories. We show a higher analogue of the above result, based on the notion of maximal $\tau_d$-rigid pairs.
We present a complete calculation of the electroweak O(alpha^3 alpha_s) corrections to three-jet production and related event-shape observables at electron--positron colliders. The Z-boson resonance is described within the complex-mass scheme, rendering the calculation valid both in the resonance and off-shell regions. Higher-order initial-state radiation is included in the leading-logarithmic approximation. We properly account for the corrections to the total hadronic cross section and for the experimental photon isolation criteria. To this end we implement contributions of the quark-to-photon fragmentation function both in the slicing and subtraction formalism. The effects of the electroweak corrections on various event-shape distributions and on the three-jet rate are studied. They are typically at the few-per-cent level, and remnants of the radiative return are found even after inclusion of appropriate cuts.
In this paper we study the dynamic versions of two basic graph problems: Minimum Dominating Set and its variant Minimum Connected Dominating Set. For those two problems, we present algorithms that maintain a solution under edge insertions and edge deletions in time $O(\Delta\cdot \text{polylog}~n)$ per update, where $\Delta$ is the maximum vertex degree in the graph. In both cases, we achieve an approximation ratio of $O(\log n)$, which is optimal up to a constant factor (under the assumption that $P \ne NP$). Although those two problems have been widely studied in the static and in the distributed settings, to the best of our knowledge we are the first to present efficient algorithms in the dynamic setting. As a further application of our approach, we also present an algorithm that maintains a Minimal Dominating Set in $O(min(\Delta, \sqrt{m}))$ per update.
All the more reason to own a gun. But while you're ate that computer search, also check for violent crime because murder is not the only problem in this world. After violent crime look into how much time someone does after committing a gun crime and who was let off or out after committing a violent crime. James T. Hodgkinson shot House Rep. Steve Scalise had a long history of violence but a short history of incarceration.
Met police recorded 149 homicides in 2019 to 30 December, up from 135 in 2018 The number of homicides in London has hit a 10-year high and there has been a surge in knife and gang-related killings since 2014, figures show. The Metropolitan police recorded 149 homicides in 2019 up to 30 December. In five years the homicide rate has increased by more than 50%, from 94 cases in 2014. Despite the introduction of a raft of measures to tackle the problem, the 2019 total was up 10% on the 135 homicides recorded in 2018, and the rise was concentrated in the poorest areas. Figures for the rest of the country are not yet available but the second biggest force, West Midlands police, reported a fall from 51 murders in 2018 to 39 in 2019. Of those 39, 19 were stabbings and three were shootings. Greater Manchester police, the third biggest force in England and Wales, said it could not provide homicide statistics. Figures from the Mayor of London’s Office for Policing and Crime (MOPAC) reveal longer-term trends in the capital. Shooting deaths in London totalled four in 2014, rose to 15 in 2018 and fell back to 12 in 2019. Fatal stabbings numbered 55 in 2014 and have gone steadily up, reaching 90 in 2019, according to Met figures. Thirty-nine people aged under 25 were killed in 2014, 66 in 2017 and 46 last year. Killings linked to gang violence have more than doubled in the last five years, from 17 in 2014 to 44 in 2018 and 42 in 2019. The youngest victim of gang-related drug violence this year was Jaden Moodie, 14, stabbed nine times by a member of a rival drug gang in east London in January. Ben Bradford, a professor of global city policing at University College London, who is working with the Met and MOPAC, said drugs, austerity and a rise in violence in youth cultures were key factors. “The top two or three explanations have something to do with [firstly] trends in the drugs market – there has been an increase in competition. There is definitely something going on around 10 years of austerity. It can’t be a coincidence that the generation of boys who were eight, nine or 10 in 2010 is coming to fruition after cuts. “There is a group of young people who are just more ready to use knives then they would’ve been in the past. There is anecdotal evidence of people carrying to protect themselves. We need to look at the demographic of the individuals and the areas they come from. It is telling that certain parts of London, certain neighbourhoods, have been more prone to violence. They are poor, neglected and left behind.” London disproportionately shapes the national debate about crime. As violent crime increased, law and order increased in importance for voters, with the Conservatives promising to halt and then reverse the big cuts they inflicted on police numbers and budgets. Furthermore, as youth services were cut, school exclusions increased. Bradford also pointed to the increasing number of young males – the group most likely to offend – in London. “The population of London is very young. There is a bulge, an increase, in the young population.” Bradford added: “The problems we are talking about do not have a policing solution. Policing is quite good at keeping the lid on problems, but it can’t provide long-term solutions. That lies with health, education and social services and they have to provide the long-term solutions.” Numbers from MOPAC shows a peak of 216 homicides in 2003. Since 2008 the figure has not risen above 155 in a calendar year. New York City, which has a similarly sized population to London and a larger police force, has double the number of homicides, reaching more than 300 in 2019 by late December. Violent crime in London is likely to be a big issue in the mayoral election in 2020, and the Conservatives will try to attack the record of the Labour incumbent, Sadiq Khan, who is seeking a second term. Susan Hall, the leader of the Conservatives in the London assembly, said: “London deserves a mayor who will act to keep our city safe and prioritise Londoners’ safety above all else.” The Met said more officers coming on stream would help, and it planned further initiatives to tackle violence. “The Met is growing and we are on track to reach 32,000 officers by late summer 2020. As these new officers join our ranks, we will be able to have more impact and begin to reverse some of the challenges the service has experienced,” a spokesperson said. “We know that drug-dealing is inextricably linked with a high proportion of the violence seen on our streets. Therefore, we will continue to target those who exploit children and target the most vulnerable within our communities.” Homicides from domestic violence reached 23 in 2019, up from 18 in 2014 but below the peak of 31 deaths in 2015. Street homicides numbered 89, up from 72 the previous year. Those in people’s homes were down to 41, from 58 in 2018.
We argue that topological compactons (solitons with compact support) may be quite common objects if $k$-fields, i.e., fields with nonstandard kinetic term, are considered, by showing that even for models with well-behaved potentials the unusual kinetic part may lead to a power-like approach to the vacuum, which is a typical signal for the existence of compactons. The related approximate scaling symmetry as well as the existence of self-similar solutions are also discussed. As an example, we discuss domain walls in a potential Skyrme model with an additional quartic term, which is just the standard quadratic term to the power two. We show that in the critical case, when the quadratic term is neglected, we get the so-called quartic $\phi^4$ model, and the corresponding topological defect becomes a compacton. Similarly, the quartic sine-Gordon compacton is also derived. Finally, we establish the existence of topological half-compactons and study their properties.
Why are "analogue spacetimes'' interesting? For the purposes of this workshop the answer is simple: Analogue spacetimes provide one with physically well-defined and physically well-understood concrete models of many of the phenomena that seem to be part of the yet incomplete theory of "quantum gravity'', or more accessibly, "quantum gravity phenomenology''. Indeed "analogue spacetimes'' provide one with concrete models of "emergence'' (whereby the effective low-energy theory can be radically different from the high-energy microphysics). They also provide many concrete and controlled models of "Lorentz symmetry breaking'', and extensions of the usual notions of pseudo-Riemannian geometry such as "rainbow spacetimes'', and pseudo-Finsler geometries, and more. I will provide an overview of the key items of "unusual physics'' that arise in analogue spacetimes, and argue that they provide us with hints of what we should be looking for in any putative theory of "quantum gravity''. For example: The dispersion relations that naturally arise in the known emergent/analogue spacetimes typically violate analogue Lorentz invariance at high energy, but do not do so in completely arbitrary manner. This suggests that a search for arbitrary violations of Lorentz invariance is possibly overkill: There are a number of natural and physically well-motivated restrictions one can put on emergent/ analogue dispersion relations, considerably reducing the plausible parameter space.
Based on the well-known cardinal characteristics $\mathfrak{s}$, $\mathfrak{r}$ and $\mathfrak{i}$, we introduce nine related cardinal characteristics by using the notion of asymptotic density to characterise different intersection properties of infinite sets. We prove several bounds and consistency results, e. g. the consistency of $\mathfrak{s} < \mathfrak{s}_{1/2}$ and $\mathfrak{s}_{1/2} < \mathrm{non}(\mathcal{N})$, as well as several results about possible values of $\mathfrak{i}_{1/2}$.
Block maxima methods constitute a fundamental part of the statistical toolbox in extreme value analysis. However, most of the corresponding theory is derived under the simplifying assumption that block maxima are independent observations from a genuine extreme value distribution. In practice however, block sizes are finite and observations from different blocks are dependent. Theory respecting the latter complications is not well developed, and, in the multivariate case, has only recently been established for disjoint blocks of a single block size. We show that using overlapping blocks instead of disjoint blocks leads to a uniform improvement in the asymptotic variance of the multivariate empirical distribution function of rescaled block maxima and any smooth functionals thereof (such as the empirical copula), without any sacrifice in the asymptotic bias. We further derive functional central limit theorems for multivariate empirical distribution functions and empirical copulas that are uniform in the block size parameter, which seems to be the first result of this kind for estimators based on block maxima in general. The theory allows for various aggregation schemes over multiple block sizes, leading to substantial improvements over the single block length case and opens the door to further methodology developments. In particular, we consider bias correction procedures that can improve the convergence rates of extreme-value estimators and shed some new light on estimation of the second-order parameter when the main purpose is bias correction.
The premise is amazing and the some of the acting, notably Sally Kellerman and Anthony Rapp, is charming... but this film is near unwatchable. The music sounds as if it comes from some sort of the royalty free online site and the lyrics as if they were written with a rhyming dictionary open on the lap. Most of the singing is off-key. I think they may have filmed with the singing accapella and put in the music under it... The dialogue is really stupid and trite. The movie works best when it is actually talking about the real estate but unfortunately it strays to often into stupid farcical sub-plots. I found myself checking my watch after ther first twenty minutes and after 40 wondering 'when is it ever going to end.'
We investigate the theory of observers in the quantum mechanical world by using a novel model of the human brain which incorporates the glial network into the Hopfield model of the neural network. Our model is based on a microscopic construction of a quantum Hamiltonian of the synaptic junctions. Using the Eguchi-Kawai large N reduction, we show that, when the number of neurons and astrocytes is exponentially large, the degrees of freedom of the dynamics of the neural and glial networks can be completely removed and, consequently, that the retention time of the superposition of the wave functions in the brain is as long as that of the microscopic quantum system of pre-synaptics sites. Based on this model, the classical information entropy of the neural-glial network is introduced. Using this quantity, we propose a criterion for the brain to be a quantum mechanical observer.
Noni Hazlehurst's tour-de-force performance (which won her an AFI award) is at least on par with her effort in FRAN three years later. Colin Friels is also good, and, for those who are interested, Alice Garner appears as Noni's child, and Michael Caton (best known for THE CASTLE) is a bearded painter. (Also interestingly, Hazlehurst is currently the host of lifestyle program BETTER HOMES AND GARDENS, and Caton is the host of property-type programs including HOT PROPERTY, HOT AUCTION, etc...) This film reaffirms the popularly-held belief that Noni was arguably Australia's top female actor during the early-to-mid 1980s. Rating: 79/100.

We report the serendipitous detection of a Wide-Angle-Tail (WAT) radio galaxy at 240 and 610 MHz, using the Giant Metrewave Radio Telescope (GMRT). This WAT is hosted by a cD galaxy PGC 1519010 whose photometric redshift given in the SDSS DR6 catalog is close to the spectroscopic redshifts (0.105, 0.106 and 0.107) of three galaxies found within 4' of the cD. Using the SDSS DR6 we have identified a total of 37 galaxies within 15' of the cD, whose photometric redshifts are between 0.08 and 0.14. This strongly suggests that the cD is associated with a group of galaxies whose conspicuous feature is a north-south chain of galaxies (filament) extending to at least 2.6 Mpc. The $ROSAT$ All-Sky Survey shows a faint, diffuse X-ray source in this direction, which probably marks the hot intra-cluster gas in the potential well of this group. We combine the radio structural information for this WAT with the galaxy clustering in that region to check its overall consistency with the models of WAT formation. The bending of the jet before and after its disruption forming the radio plume, are found to be correlated in this WAT, as seen from the contrasting morphological patterns on the two sides of the core. Probable constraints imposed by this on the models of WAT formation are pointed out. We also briefly report on the other interesting radio sources found in the proximity of the WAT. These include a highly asymmetric double radio source and an ultra-steep spectrum radio source for which no optical counterpart is detected in the SDSS.
There is no need for me to repeat the synopsis rendered by Glenn. The black and white rendition is even more powerful in portraying the bleakness of country village life at that time. The deep measure of friendship shown by Babette toward the two elderly sisters touches the heart strings. The supporting cast is excellent and their performances superb, it would not be fair to single out any one character since the entire story depends on the cast as a whole. I cannot put my finger exactly on why I rate this movie so highly since I am not a professional critic; individual viewers may or may not agree with my rating since enjoyment of this type of movie is always in the eye of the beholder.
Recent work has studied the reasons for the remarkable performance of deep neural networks in image classification. We examine batch normalization on the one hand and the dynamical systems view of residual networks on the other hand. Our goal is in understanding the notions of stability and smoothness of the inter-layer propagation of ResNets so as to explain when they contribute to significantly enhanced performance. We postulate that such stability is of importance for the trained ResNet to transfer.
Can you explain that? There are reports everywhere of green card holders being denied entry to the US today. US citizens cannot be turned back at the border, but green card holders are still in the citizenship process and don't have any kind of constitutional guarantee. I've seen an argument that it might not be legal to discriminate against green card holders on the basis of nationality, but there is nothing in the text of Trump's executive order that exempts them.
The massive interacting binary RY Scuti is an important representative of an active mass-transferring system that is changing before our eyes and which may be an example of the formation of a Wolf-Rayet star through tidal stripping. Utilizing new and previously published spectra, we present examples of how a number of illustrative absorption and emission features vary during the binary orbit. We identify spectral features associated with each component, calculate a new, double-lined spectroscopic binary orbit, and find masses of 7.1 +/- 1.2 M_sun for the bright supergiant and 30.0 +/- 2.1 M_sun for the hidden massive companion. Through tomographic reconstruction of the component spectra from the composite spectra, we confirm the O9.7 Ibpe spectral class of the bright supergiant and discover a B0.5 I spectrum associated with the hidden massive companion; however, we suggest that the latter is actually the spectrum of the photosphere of the accretion torus immediately surrounding the massive companion. We describe the complex nature of the mass loss flows from the system in the context of recent hydrodynamical models for beta Lyr, leading us to conclude RY Scuti has matter leaving the system in two ways: 1) a bipolar outflow from winds generated by the hidden massive companion, and 2) mass from the bright O9.7 Ibpe supergiant flowing from the region near the L2 point to fill out a large, dense circumbinary disk. This circumbinary disk (radius ~ 1 AU) may feed the surrounding double-toroidal nebula (radius ~ 2000 AU).
By employing the perturbative QCD (PQCD) factorization approach, we studied the sixteen $B/B_s \to \eta_c (\pi, K, \eta^{(\prime)},\rho,K^*,\omega,\phi)$ decays with the inclusion of the currently known next-to-leading order (NLO) contributions. We found the following main points: (a) for the five measured $B \to \eta_c (K,K^*)$ and $B_s\to \eta_c\phi$ decays, the NLO contributions can provide $ (80-180)\%$ enhancements to the leading order (LO) PQCD predictions of their branching ratios, which play an important role to help us to interpret the data; (b) for the seven ratios $R_{1,\cdots,7}$ of the branching ratios defined among the properly selected pair of the considered decay modes, the PQCD predictions for the values of $R_{3,4,5}$ agree well with those currently available measurements from BaBar and Belle Collaboration; (c) for $B^0 \to \eta_c K_S^0$ decay, the PQCD predictions for both the direct and mixing induced CP asymmetries do agree very well with the measured values within errors; and (d) the PQCD predictions for ratios $R_{1,2}$ and $R_{6,7}$ also agree with the general expectations and will be tested by the future experiments.
My wife and I saw this when we were 17. The only good thing my father ever did (get us in). This is "our movie" and the music is "our songs". Michelle's song is "our" song. Yeah, nowadays, it's a crime to show naked children on the screen, but we were screwing at 16, why not these kids? The movie is- rich boy impregnates poor girl, then rich dad steals him away from her at the end, after she gives birth under impoverished conditions. She is left alone with child. It is a love story and a "growing up" story. The music is fantastic, and the story is one any person could relate to. May be someday this will be released on DVD.
The absorption cross section of highly luminescent individual single-walled carbon nanotubes is determined using time-resolved and cw luminescence spectroscopy. A mean value of 1x10-17 cm2 per carbon atom is obtained for (6,5) tubes excited at their second optical transition, and corroborated by single tube photothermal absorption measurements. Biexponential luminescence decays are systematically observed, with short and long lifetimes around 45 and 250 ps. This behavior is attributed to the band edge exciton fine structure with a dark level lying a few meV below a bright one.
In this letter, we present the first 3D force-free general relativity simulations of the magnetosphere dynamics related to the magnetar outburst/flare phenomenology. Starting from an initial dipole configuration, we adiabatically increase the helicity by twisting the footprints of a spot on the stellar surface and follow the succession of quasi-equilibrium states until a critical twist is reached. Twisting beyond that point triggers instabilities that results in the rapid expansion of magnetic field lines, followed by reconnection, as observed in previous axi-symmetric simulations. If the injection of magnetic helicity goes on, the process is recurrent, periodically releasing a similar amount of energy, of the order of a few % of the total magnetic energy. From our current distribution, we estimate the local temperature assuming that dissipation occurs mainly in the highly resistive outermost layer of the neutron star. We find that the temperature smoothly increases with injected twist, being larger for spots located in the tropical regions than in polar regions, and rather independent of their sizes. After the injection of helicity ceases, the magnetosphere relaxes to a new stable state, in which the persistent currents maintain the footprints area slightly hotter than before the onset of the instability.
We propose an algorithm to find a solution to an integro-differential equation of the DGLAP type for all the orders in the running coupling $\alpha$ with splitting functions given at a fixed order in $\alpha.$ Complex analysis is significantly used in the construction of the algorithm, we found a simpler way to calculate the involved integrals over contours in the complex planes than by any of the methods known at present.
It's initial premise is based on the American Civil War but it's ultimately a love story. We start at the beginning of the war where the main characters (Kidman & Law) are obviously aware of each other and there's an obvious attraction, they have a passionate kiss on the day he leaves for the war. The main thrust of this film is for Law's character to return to Kidman's and his struggles to achieve that and her struggles to survive until he returns. The reason it fails to convince is that we don't see enough of this relationship before Law's character leaves for battle - it's difficult to believe the premise that 2 people yearn for each other so much given they've had so little contact. Everything else is just about fine, Renee Zellweger and her incumbent father and his entourage are lovely additions as is the threat from the gang chasing deserters. Sure it's a long film but it does hold the interest and the cinematography is great. An honourable attempt that doesn't quite make it but worth a watch nonetheless.
We perform a calculation of inclusive $Z$ boson production in proton-lead collisions at the LHC taking into account the transverse momenta of the initial partons. We use the framework of $k_T$-factorization combining transverse momentum dependent parton distributions (TMDs) with off-shell matrix elements. In order to do it we need to construct appropriate TMDs for lead nuclei which is done using the parton branching method. Our computations are compared with data from CMS taken at $\sqrt{s}=5.02$ TeV. The results are in good agreement with the measurements especially the transverse momentum distribution of the $Z$ boson.
Given a positive definite covariance matrix $\widehat \Sigma$, we strive to construct an optimal \emph{approximate} factor analysis model $HH^\top +D$, with $H$ having a prescribed number of columns and $D>0$ diagonal. The optimality criterion we minimize is the I-divergence between the corresponding normal laws. Lifting the problem into a properly chosen larger space enables us to derive an alternating minimization algorithm \`a la Csisz\'ar-Tusn\'ady for the construction of the best approximation. The convergence properties of the algorithm are studied, with special attention given to the case where $D$ is singular.
This was one of the best shows ever made for TV. Full of mystery and intrigue and twists and turns. Compulsive viewing. I was lucky I saw this in the UK. They might have got the episode order wrong, I can't remember, but it at least was on at a regular time every week. My girlfriend and I got hooked from the trailer in, and neither of us is a big fan of American series normally.<br /><br />After the pilot, we knew this was something special. We missed a couple of episodes, and it made you sad and mad for a week missing those ones lol.<br /><br />Great casting, superb acting. Gary Cole was absolutely brilliant, better even than his role as Custer. Lucas Black turned in an amazing performance for a kid, and Paige Turco was at her best too since Party of Five. And Nick Searcy of course, as the Sheriff's long suffering sidekick.<br /><br />Yes, there were some confusing and perplexing bits, which I presume would have been explained later, and no doubt would have been in a later series. That made the ending weak, and you could tell they'd killed it. Made us go WHAT? Why did they do that with one of the best shows ever? Shoot the exec.
This paper introduced NgViz, a tool that examines DNS traffic and shows anomalies in n-gram frequencies. This is accomplished by comparing input files against a fingerprint of legitimate traffic. Both quantitative analysis and visual aids are provided that allow the user to make determinations about the legitimacy of the DNS traffic.
Do not purchase, not happy at all. Not as advertised at all. This screen protector has almost a matte feel and look to it, this protector makes the screen have a slight blur to it as well. When using the cleaning wipes, they left a residue and I had to get a different cloth and cleaner to clear it up before installing. The instructions on the package are not for the screen protectors sent with it. I will be attempting a return.
Usually it is supposed that Majorana neutrino produced in the superposition state $\chi_L = \nu_L + (\nu_L)^c$ and then follows the neutrinoless double beta decay. But since weak interactions are chiral invariant then the neutrino at production has definite helicity (i.e., $\nu_L$ and $(\nu_L)^c$ neutrinos are separately produced and then neutrino is not in the superposition state). This helicity cannot change after production without any external interactions. Thus we see that for unsuitable helicity the neutrinoless double $\beta$ decay is not possible even if neutrino is a Majorana particle. Also transition of Majorana neutrino into antineutrino at their oscillations is forbidden since helicity in vacuum holds. Then only possibility to prove that neutrino is a Dirac but not Majorana particle is detection transition of $\nu_L$ neutrino into (sterile) antineutrino $\bar\nu_R$ (i.e., $\nu_L \to \bar\nu_R$) at neutrino oscillations. Transition Majora neutrino $\nu_L$ into $(\nu_R)^c$ (i.e., $\nu_L \to (\nu_R)^c$) at oscillations is unobserved since it is supposed that mass of $(\nu_R)^c$ is very big.
Actually works! As a recreational griller at best, I did a lot of research on pellet grills. Depending on what you want, size wise, I will vouch for the brand that everything works. Steady temp, easy Wi-fi connections, great customer service. I would suggest if you are cooking for more than 4, you should look at their bigger units.
Understanding the retention and recycling of hydrogen isotopes in liquid metal plasma-facing materials such as liquid Li, Sn, and Li-Sn are of fundamental importance in designing magnetically confined fusion reactors. We perform first-principles molecules dynamics simulations of liquid Li-Sn slab with inserted D atoms to provide microscopic insights into the interactions of D with Li-Sn liquid metal. We observe evaporation of D$_2$ and LiD molecules out of the Li-Sn slabs. With detailed analysis, we unveil a cooperative process of forming D$_2$ molecules in liquid Li-Sn, where Li atoms act as catalytic centers to trap a D atom before another D comes nearby to form a molecule, and the surplus charges are transferred from D$_2$ to nearby Sn atoms. Furthermore, we predict a temperature window in which D$_2$ molecules can escape to vacuum, while LiD molecules cannot. The above findings deepen our understanding of interactions between hydrogen isotopes and Li-Sn liquid metal.
In this paper, a class of relay networks is considered. We assume that, at a node, outgoing channels to its neighbors are orthogonal, while incoming signals from neighbors can interfere with each other. We are interested in the multicast capacity of these networks. As a subclass, we first focus on Gaussian relay networks with interference and find an achievable rate using a lattice coding scheme. It is shown that there is a constant gap between our achievable rate and the information theoretic cut-set bound. This is similar to the recent result by Avestimehr, Diggavi, and Tse, who showed such an approximate characterization of the capacity of general Gaussian relay networks. However, our achievability uses a structured code instead of a random one. Using the same idea used in the Gaussian case, we also consider linear finite-field symmetric networks with interference and characterize the capacity using a linear coding scheme.
We consider a Min-Power Bounded-Hops Symmetric Connectivity problem that consists in the construction of communication spanning tree on a given graph, where the total energy consumption spent for the data transmission is minimized and the maximum number of hops between two nodes is bounded by some predefined constant. We focus on the planar Euclidian case of this problem where the nodes are placed at the random uniformly spread points on a square and the power cost necessary for the communication between two network elements is proportional to the squared distance between them. Since this is an NP-hard problem, we propose different polynomial heuristic algorithms for the approximation solution to this problem. We perform a posteriori comparative analysis of the proposed algorithms and present the obtained results in this paper.
Experimental demonstration of the quantum advantage over classical simulations with Boson Sampling is currently under intensive investigation. There seems to be a scalability issue to the necessary number of bosons on the linear optical platforms and the experiments, such as the recent Boson Sampling with $20$ photons on $60$-port interferometer by H.~Wang~\textit{et al}, \textit{Phys. Rev. Lett.} \textbf{123,} 250503 (2019), are usually carried out on a small interferometer, much smaller than the size necessary for the no-collision regime. Before demonstration of quantum advantage, it is urgent to estimate exactly how the classical computations necessary for sampling from the output distribution of Boson Sampling are reduced when a smaller-size interferometer is used. The present work supplies such a result, valid with arbitrarily close to $1$ probability, which reduces in the no-collision regime to the previous estimate by P.~Clifford and R.~Clifford. One of the results with immediate application to current experiments with Boson Sampling is that classically sampling from the interference of $N$ single bosons on an $M$-port interferometer is at least as hard as that with $\mathcal{N}= \frac{N}{1+N/M}$ single bosons in the no-collision regime, i.e., on a much larger interferometer with at least $\mathcal{M}\gg N^2$ ports.
Besides a git-based version control system, GitHub integrates several social coding features. Particularly, GitHub users can star a repository, presumably to manifest interest or satisfaction with an open source project. However, the real and practical meaning of starring a project was never the subject of an in-depth and well-founded empirical investigation. Therefore, we provide in this paper a throughout study on the meaning, characteristics, and dynamic growth of GitHub stars. First, by surveying 791 developers, we report that three out of four developers consider the number of stars before using or contributing to a GitHub project. Then, we report a quantitative analysis on the characteristics of the top-5,000 most starred GitHub repositories. We propose four patterns to describe stars growth, which are derived after clustering the time series representing the number of stars of the studied repositories; we also reveal the perception of 115 developers about these growth patterns. To conclude, we provide a list of recommendations to open source project managers (e.g., on the importance of social media promotion) and to GitHub users and Software Engineering researchers (e.g., on the risks faced when selecting projects by GitHub stars).
The effect of confinement in the segmental relaxation of polymers is considered. On the basis of a thermodynamic model we discuss the emerging relevance of the fast degrees of freedom in stimulating the much slower segmental relaxation, as an effect of the constraints at the walls of the amorphous regions. In the case that confinement is due to the presence of crystalline domains, a quasi-poissonian distribution of local constraining conditions is derived as a result of thermodynamic equilibrium. This implies that the average free energy barrier $\Delta F$ for conformational rearrangement is of the same order of the dispersion of the barrier heights, $\delta (\Delta F)$, around $\Delta F$. As an example, we apply the results to the analysis of the $\alpha$-relaxation as observed by dielectric broad band spectroscopy in semicrystalline poly(ethylene terephthalate) cold-crystallized from either an isotropic or an oriented glass. It is found that in the latter case the regions of cooperative rearrangement are significantly larger than in the former.
Motivated by slow-roll inflationary cosmology we study a scalar unparticle weakly coupled to a Higgs field in the broken symmetry phase. The mixing between the unparticle and the Higgs field results in a seesaw type matrix and the mixing angles feature a Mikheyev-Smirnov-Wolfenstein (MSW) effect as a consequence of the unparticle field being noncanonical. We find two (MSW) resonances for small and large spacelike momenta. The unparticlelike mode features a nearly flat potential with spinodal instabilities and a large expectation value. An effective potential for the unparticlelike field is generated from the Higgs potential, but with couplings suppressed by a large power of the small seesaw ratio. The dispersion relation for the Higgs-like mode features an imaginary part even at "tree level" as a consequence of the fact that the unparticle field describes a multiparticle continuum. Mixed unparticle-Higgs propagators reveal the possibility of oscillations, albeit with short coherence lengths. The results are generalized to the case in which the unparticle features a mass gap, in which case a low energy MSW resonance may occur for lightlike momenta depending on the scales. Unparticle-Higgs mixing leads to an effective unparticle potential of the new-inflation form. Slow-roll variables are suppressed by seesaw ratios and the anomalous dimensions and favor a red spectrum of scalar perturbations consistent with cosmic microwave background data.
And believe me that's a pretty stunning accomplishment. Take "Jolly Roger: Massacre at Cutter's Cove," change the killer from a pirate to a prospector, change his obsession from buried treasure to old gold, and his color from puke green to deep blue. You now have "Miner's Massacre." The problem is, at least "Jolly Roger" was entertaining enough -- albeit in a so-bad-it's-good way -- to keep you watching it for the whole two hours. There's no strip-joint-murder scene or any bizarre killings. I can't tell you how many times I lost interest in "Miner's Massacre" and started doing dishes or cleaning around the condo. And, the ending is absolutely silly. The 49er dude just randomly re-appears out of nowhere to kill the local sheriff, while the lead actor and actress are sitting in the sheriff's cruiser, screaming. A truly horrible movie.

I watched the MST3K version of the movie, and this review includes minor spoilers.<br /><br />When I started watching this movie, it looked like it might have promise as a cheesy sci-fi flick, but the more I watched it, the more disappointing it got. The first reason is pretty idiosyncratic - I liked the mousy shy girl with glasses a lot more than the model Wanda became by the end of the movie. More deeply, it was the fact that the loss of glasses and change in clothing replaced any actual character growth. Instead of growing into a character that could take care of herself, Wanda was just as dependent on males to do everything for her as she was at the start of the movie. The acting could have been better (though I got tired of cracks about Ireland's voice - they were even in the movie itself! It's not that bad.) The background was okay, but it was a little hokey (aliens = humans with facepaint), and could have used more explanation.<br /><br />Maybe it was just that I was interested in the movie itself, but Joel and the bots did little for me. The movie might have been better without them at all.<br /><br />Overall (for the movie itself, not the MST3K), a 3 out of 10. It was an okay flick, for what it was.
Elf Light Rose I ordered this in Elf Light Rose and it is a lot more orange than pictured. It also smells/tastes strongly of dish soap, which does not fade after you put it on. The color also clings to any dry spots on your lips and emphasizes lines. Disappointing, since I own this product in other colors and I have had much better experiences.
Random field excursions is an increasingly vital topic within data analysis in medicine, cosmology, materials science, etc. This work is the first detailed study of their Betti numbers in the so-called `sparse' regime. Specifically, we consider a piecewise constant Gaussian field whose covariance function is positive and satisfies some local, boundedness, and decay rate conditions. We model its excursion set via a Cech complex. For Betti numbers of this complex, we then prove various limit theorems as the window size and the excursion level together grow to infinity. Our results include asymptotic mean and variance estimates, a vanishing to non-vanishing phase transition with a precise estimate of the transition threshold, and a weak law in the non-vanishing regime. We further obtain a Poisson approximation and a central limit theorem close to the transition threshold. Our proofs combine extreme value theory and combinatorial topology tools.
"But more intense storms are what scientists expect to see as the planet’s climate changes because warmer ocean water is fuel for hurricanes". However how does this play if climate change is melting the poles. Think ice in warm water. Is it possible these more intense storms are because there isn't global warming. It's also interesting that hurricane season, is from late spring to early fall. Over the summer when the sun is in the Northern Hemisphere, and when the water in the Atlantic is the warmest.
We conjecture that the p-adic L-function of a non-trivial irreducible even Artin character over a totally real field is non-zero at all non-zero integers. This implies that a conjecture formulated by Coates and Lichtenbaum at negative integers extends in a suitable way to all positive integers. We also state a conjecture that for certain characters the Iwasawa series underlying the p-adic L-series have no multiple roots except for those corresponding to the zero at s=0 of the p-adic L-function. We provide some theoretical evidence for our first conjecture, and prove both conjectures by means of computer calculations for a large set of characters (and integers where appropriate) over the rationals and over real quadratic fields, thus proving many instances of conjectures by Coates and Lichtenbaum and by Schneider. The calculations and the theoretical evidence also prove that certain p-adic regulators corresponding to 1-dimensional characters for the rational numbers are units in many cases. We also verify Gross' conjecture for the order of the zero of the p-adic L-function at s=0 in many cases. We gather substantial statistical data on the constant term of the underlying Iwasawa series, and propose a model for its behaviour for certain characters.
We study the dynamics of a particle moving in one-dimensional Lorentz lattice-gas where particle performs mainly three different kinds of motion {\it viz} ballistic motion, diffusion and confinement. There are two different types of scatterers, {\it viz} reflector and transmitters, randomly placed in the lattice. Reflectors are such that they reverse the particle's velocity direction and transmitters let it pass through. Scatterers also change their character with flipping probability $1-\alpha$, once the particle interacts with a scatterer. Hence the system is defined by two sets of parameters, $r$, which is the initial density of reflector/transmitter and $\alpha$. For $\alpha=0$ and $\alpha=1$ dynamics of the particle is purely deterministic else it is probabilistic. In the pure deterministic case dynamics of the particle is either propagation in one direction or confined between two near-by reflectors present. For the probabilistic case $\alpha \ne 1$ and $\ne 0$, although the dynamics of particle shows anomalous diffusion where dynamics is faster, slower and comparable to normal diffusion on the variation of system parameters $(\alpha, r)$, but the asymptotic behaviour of the particle is normal diffusion. We plot the phase diagram for the asymptotic behaviour, in the plane of $\alpha$ and $r$.
Among the most important graph parameters is the Diameter, the largest distance between any two vertices. There are no known very efficient algorithms for computing the Diameter exactly. Thus, much research has been devoted to how fast this parameter can be approximated. Chechik et al. showed that the diameter can be approximated within a multiplicative factor of $3/2$ in $\tilde{O}(m^{3/2})$ time. Furthermore, Roditty and Vassilevska W. showed that unless the Strong Exponential Time Hypothesis (SETH) fails, no $O(n^{2-\epsilon})$ time algorithm can achieve an approximation factor better than $3/2$ in sparse graphs. Thus the above algorithm is essentially optimal for sparse graphs for approximation factors less than $3/2$. It was, however, completely plausible that a $3/2$-approximation is possible in linear time. In this work we conditionally rule out such a possibility by showing that unless SETH fails no $O(m^{3/2-\epsilon})$ time algorithm can achieve an approximation factor better than $5/3$. Another fundamental set of graph parameters are the Eccentricities. The Eccentricity of a vertex $v$ is the distance between $v$ and the farthest vertex from $v$. Chechik et al. showed that the Eccentricities of all vertices can be approximated within a factor of $5/3$ in $\tilde{O}(m^{3/2})$ time and Abboud et al. showed that no $O(n^{2-\epsilon})$ algorithm can achieve better than $5/3$ approximation in sparse graphs. We show that the runtime of the $5/3$ approximation algorithm is also optimal under SETH. We also show that no near-linear time algorithm can achieve a better than $2$ approximation for the Eccentricities and that this is essentially tight: we give an algorithm that approximates Eccentricities within a $2+\delta$ factor in $\tilde{O}(m/\delta)$ time for any $0<\delta<1$. This beats all Eccentricity algorithms in Cairo et al.
Opioid overdose is a growing public health crisis in the United States. This crisis, recognized as "opioid epidemic," has widespread societal consequences including the degradation of health, and the increase in crime rates and family problems. To improve the overdose surveillance and to identify the areas in need of prevention effort, in this work, we focus on forecasting opioid overdose using real-time crime dynamics. Previous work identified various types of links between opioid use and criminal activities, such as financial motives and common causes. Motivated by these observations, we propose a novel spatio-temporal predictive model for opioid overdose forecasting by leveraging the spatio-temporal patterns of crime incidents. Our proposed model incorporates multi-head attentional networks to learn different representation subspaces of features. Such deep learning architecture, called "community-attentive" networks, allows the prediction of a given location to be optimized by a mixture of groups (i.e., communities) of regions. In addition, our proposed model allows for interpreting what features, from what communities, have more contributions to predicting local incidents as well as how these communities are captured through forecasting. Our results on two real-world overdose datasets indicate that our model achieves superior forecasting performance and provides meaningful interpretations in terms of spatio-temporal relationships between the dynamics of crime and that of opioid overdose.
We investigate cross-correlations in the tunneling currents through two parallel quantum dots coupled to independent electrodes and gates and interacting via an inter-dot Coulomb interaction. The correlations reveal additional information, beyond what can be learned from the current or conductance, about the dynamics of transport processes of the system. We find qualitatively different scenarios for the dependence of the cross-correlations on the two gate voltages. Reducing the temperature below the inter-dot Coulomb interaction, regions of a given sign change from spherical shapes to angular L-shapes or stripes. Similar shapes have been observed in recent experiments.
In the framework of Generalised Parton Distributions, we study the helicity-dependent and independent cross sections measured in Hall A and the beam spin asymmetries measured in Hall B at Jefferson Laboratory. We perform a global fit of these data and fits on each kinematical bin. We extract the real and imaginary parts of the Compton Form Factor $\mathcal{H}$ under the main hypothesis of dominance of the Generalised Parton Distribution $H$ and twist 2 accuracy. We discuss our results and compare to previous extractions as well as to the VGG model. We pay extra attention to the estimation of errors on the extraction of $\mathcal{H}$.
Let $M$ be a compact Riemannian manifold with boundary $\pp M$ and $L= \DD+Z$ for a $C^1$-vector field $Z$ on $M$. Several equivalent statements, including the gradient and Poincar\'e/log-Sobolev type inequalities of the Neumann semigroup generated by $L$, are presented for lower bound conditions on the curvature of $L$ and the second fundamental form of $\pp M$. The main result not only generalizes the corresponding known ones on manifolds without boundary, but also clarifies the role of the second fundamental form in the analysis of the Neumann semigroup. Moreover, the L\'evy-Gromov isoperimetric inequality is also studied on manifolds with boundary.
Christmas isn't over just yet. Eight people have been named to Order of Newfoundland and Labrador, including Santa's longtime stand-in, Bruce Templeton. Templeton, of Outer Cove, has been invested into the order for his decades of volunteer work, community leadership and humanitarianism — including more than 40 years of playing Santa — as well as published books and charity work. An investiture ceremony will be held on Jan. 29 at Government House in St. John's, where Templeton's name will be joining the 118 recipients in the 13 ceremonies since the order began in 2004. "As Chancellor of the Order of Newfoundland and Labrador, it will be an honour to invest eight fellow Newfoundlanders and Labradorians, who have made outstanding contributions to our province and people, into the Order of Newfoundland and Labrador, the province's highest level of recognition," said Lt.-Gov. Judy Foote in a news release on Tuesday. "I look forward to thanking each of them personally at the investiture ceremony on Jan. 29 for the many efforts they have made, and continue to make, to ensure our province is the best it can be." With new appointees set to receive their honours, 118 people will have been invested into the Order of Newfoundland and Labrador. (Jeremy Eaton/CBC) Joining Templeton will be Jim Burton of Portugal Cove-St. Phillip's, Elaine Dobbin of Portugal Cove-St. Phillip's, Robert Lyall of Happy Valley-Goose Bay, Helen Murphy of St. John's, Myles Murphy of St. John's, Susan Rose of Broad Cove and Gordon Slade of Mount Pearl. The Order of Newfoundland and Labrador recognizes individuals who have demonstrated excellence and achievement in an exemplary manner for the province and its residents, according to government. Appointments to the Order are made by the chancellor on the recommendation of its advisory council. "These eight individuals are determined to make a difference where and when they can for which I thank them on behalf of all the people of Newfoundland and Labrador," Foote said.

Button for fly failed the 1st time I put them on. The main button literally fell off in my hand the 1st time I put them on. This is just poor quality control/manufacturing. I immediately took them off and dropped them off w/ my seamstress with instructions to double-stitch all of the buttons. For this his added cost, I could have just purchased a more expensive product that may have better quality checks before shipping. Aside from this issue, I suspect the pants will be just fine.
This paper presents three fully convolutional neural network architectures which perform change detection using a pair of coregistered images. Most notably, we propose two Siamese extensions of fully convolutional networks which use heuristics about the current problem to achieve the best results in our tests on two open change detection datasets, using both RGB and multispectral images. We show that our system is able to learn from scratch using annotated change detection images. Our architectures achieve better performance than previously proposed methods, while being at least 500 times faster than related systems. This work is a step towards efficient processing of data from large scale Earth observation systems such as Copernicus or Landsat.
An unusual mystery series. I recommend it for anyone looking for so different. I love this series. Lucy and the vampires once again investigate a murder. I like how Lucy struggles with learning how to knit and her magical powers. I liked learning more about the lives of the vampires when they were human. Those backgrounds helped with the invest. I love the humor, and Lucy's interest in a handsome police officer. This is a good read and mystery.
8 Simple Rules is a funny show but it also has some life lessons especially one mature lesson about moving on after a lose which was the episode where Paul died which was the first episode I have ever watched of the show that comes on ABC. The Hennessy clan -- mother Cate (Katey Sagal), daughters Bridget (Kaley Cuoco) and Kerry (Amy Davidson), and son Rory (Martin Spanjers) -- look to one another for guidance and support after the death of Paul (John Ritter), the family patriarch. Cate's parents (James Garner and Suzanne Pleshette) lend a hand. I am glad later in the 2nd season of this show they decided to put David Spade in this show since he was done with the NBC series, Just Shoot Me! But all and all this show is pretty good. This show reminds me a lot of the classic family sitcoms from the 80's and 90's that used to be on ABC.
The problem with TV today is that people have been spoiled by "lite" TV viewing. This type of television show is the equivalent of elevator music or "easy listening" jazz. The typical viewers idea of "continuity" is remembering who got voted off the island last week and wondering who will be the next to go. Show them a program like surface, Firefly, Dr. Who, or anything with a plot arc of more than three episodes and...well, they'll just flip back to Survivor.<br /><br />95% of the sheep watching TV don't want to rack their brains. They want excuses to not think. They want to make sure the "boob tube" lives up to its name...and they don't want shows that try and go any other route. Because of this, Surface and many other high-quality shows that should have lasted far longer have gotten the axe.<br /><br />TV viewers don't want stories, or morals, or philosophy, or anything over a third grade vocabulary level. They want people eating earthworms, or over-dramatized "real life" series (no such thing! You cannot observe something without changing the very nature of what you observe) or hormonal shows involving groups of people having trysts and then bragging about it to their friends.<br /><br />Today's television is nothing but a wasteland, and the few diamonds you can pick out of the dust are just tossed out because no one even knows what a diamond is anymore. Surface was one of those diamonds.
Magnetic resonance imaging (MRI) reconstruction is an active inverse problem which can be addressed by conventional compressed sensing (CS) MRI algorithms that exploit the sparse nature of MRI in an iterative optimization-based manner. However, two main drawbacks of iterative optimization-based CSMRI methods are time-consuming and are limited in model capacity. Meanwhile, one main challenge for recent deep learning-based CSMRI is the trade-off between model performance and network size. To address the above issues, we develop a new multi-scale dilated network for MRI reconstruction with high speed and outstanding performance. Comparing to convolutional kernels with same receptive fields, dilated convolutions reduce network parameters with smaller kernels and expand receptive fields of kernels to obtain almost same information. To maintain the abundance of features, we present global and local residual learnings to extract more image edges and details. Then we utilize concatenation layers to fuse multi-scale features and residual learnings for better reconstruction. Compared with several non-deep and deep learning CSMRI algorithms, the proposed method yields better reconstruction accuracy and noticeable visual improvements. In addition, we perform the noisy setting to verify the model stability, and then extend the proposed model on a MRI super-resolution task.
Although the 2P3/2-2P1/2 transition of [CII] at 158um is known to be an excellent tracer of active star formation, we still do not have a complete understanding of where within star formation regions the emission originates. Here, we use SOFIA upGREAT observations of [CII] emission toward the HII region complex Sh2-235 (S235) to better understand in detail the origin of [CII] emission. We complement these data with a fully-sampled Green Bank Telescope radio recombination line map tracing the ionized hydrogen gas. About half of the total [CII] emission associated with S235 is spatially coincident with ionized hydrogen gas, although spectroscopic analysis shows little evidence that this emission is coming from the ionized hydrogen volume. Velocity-integrated [CII] intensity is strongly correlated with WISE 12um intensity across the entire complex, indicating that both trace ultra-violet radiation fields. The 22um and radio continuum intensities are only correlated with [CII] intensity in the ionized hydrogen portion of the S235 region and the correlations between the [CII] and molecular gas tracers are poor across the region. We find similar results for emission averaged over a sample of external galaxies, although the strength of the correlations is weaker. Therefore, although many tracers are correlated with the strength of [CII] emission, only WISE 12um emission is correlated on small-scales of the individual HII region S235 and also has a decent correlation at the scale of entire galaxies. Future studies of a larger sample of Galactic HII regions would help to determine whether these results are truly representative.
I saw this when it first came out and have seen it several times since. I have the DVD. It's one of Drew Barrymore's best works and one that is worth seeing more than once. <br /><br />Not being popular in high school was one f the things in the film I could relate to. I wasn't quite as tortured as Josie was (during her real high school days) or like Aldys, but I was never the go- to-the-major-party type either. The prom scene were the three popular girls fall victim to their own prank as Josie pushes way Aldys (the intended victim) is my favorite scene and I clapped when I first saw it. <br /><br />I can still watch this movie today. it is excellent.
It seems we are in agreement about both personal forgiveness AND civil punishment. I have long since come to realize that a lot of what consumed my anger towards others was really self inflicted punishment. This included my relationship with a brother who left me holding the bag too many times. I was furious about stuff like his wrecking my car with just a oops to take its place. I should have forgiven him years ago. Imagine my surprise when he called me to tell me he had just found out he had a very virulent form of cancer and that I was the first person he wanted to talk with, before even calling his own kids. Over the next 4 months we had many great conversations that his wife told me helped him out a lot. Sadly, during what was to be our last conversation he started to have some bad coughing and we needed to stop the call. Before calling I had decided to tell him that I totally forgave him, but held back because of how weak he sounded. Lost my chance he died.
We present a numerical study of the flow of an assembly of frictionless soft discs at zero temperature, in the vicinity of and slightly above the jamming density. We find that some of the flow properties, such as the fluctuations in the number of contacts or the shear modulus, display a critical like behaviour that is governed by the proximity to the jamming point. Dynamical correlations during a quasistatic deformation, however, are non critical and dominated by system size. At finite strain rates, these dynamical correlations acquire a finite, strain-rate dependent amplitude, that decreases when approaching the jamming point from above.
