We introduce GQA, a new dataset for real-world visual reasoning and
compositional question answering, seeking to address key shortcomings of
previous VQA datasets. We have developed a strong and robust question engine
that leverages scene graph structures to create 22M diverse reasoning
questions, all come with functional programs that represent their semantics. We
use the programs to gain tight control over the answer distribution and present
a new tunable smoothing technique to mitigate question biases. Accompanying the
dataset is a suite of new metrics that evaluate essential qualities such as
consistency, grounding and plausibility. An extensive analysis is performed for
baselines as well as state-of-the-art models, providing fine-grained results
for different question types and topologies. Whereas a blind LSTM obtains mere
42.1%, and strong VQA models achieve 54.1%, human performance tops at 89.3%,
offering ample opportunity for new research to explore. We strongly hope GQA
will provide an enabling resource for the next generation of models with
enhanced robustness, improved consistency, and deeper semantic understanding
for images and language.

Classic long-john for regular use
Husband loves classic long-johns, not the new expensive thin ones, and these are just that. Cotton blend, not tights. Fit as expected. He wears 33" waist Lee jeans and Medium fits perfect. He said the ankles are a little tight to pull on but once on they are fine.

Multi-socket machines with 1-100 TBs of physical memory are becoming
prevalent. Applications running on multi-socket machines suffer non-uniform
bandwidth and latency when accessing physical memory. Decades of research have
focused on data allocation and placement policies in NUMA settings, but there
have been no studies on the question of how to place page-tables amongst
sockets. We make the case for explicit page-table allocation policies and show
that page-table placement is becoming crucial to overall performance. We
propose Mitosis to mitigate NUMA effects on page-table walks by transparently
replicating and migrating page-tables across sockets without application
changes. This reduces the frequency of accesses to remote NUMA nodes when
performing page-table walks. Mitosis uses two components: (i) a mechanism to
enable efficient page-table replication and migration; and (ii) policies for
processes to efficiently manage and control page-table replication and
migration. We implement Mitosis in Linux and evaluate its benefits on real
hardware. Mitosis improves performance for large-scale multi-socket workloads
by up to 1.34x by replicating page-tables across sockets. Moreover, it improves
performance by up to 3.24x in cases when the OS migrates a process across
sockets by enabling cross-socket page-table migration.

Watching this PPV, I had high expectations for it, since Smackdown is the best show in WWE, this is a very good PPV as it is the last one before Wrestlemania.<br /><br />FIRST MATCH-HARDY BOYS & CHRIS BENOIT VS. MVP & MNM W/ MELINA IN A 6 MAN TAG TEAM MATCH Good way to start the match. It started a bit slow at the start, but later the pace quickened & the match got more exciting & entertaining. Benoit rolls through & makes Joey Mercury tap out to get a victory for the Hardy Boys & himself. 6/10<br /><br />SECOND MATCH- GREGORY HELMS {CHAMPION} VS. SHANNON MOORE VS. FUNAKI VS. CHAVO GUERRERO VS. DAIVAIRI VS. SCOTTY 2 HOTTY VS. JAMIE NOBLE VS. JIMMY WANG YANG IN AN OPEN CRUISERWEIGHT INVITATIONAL MATCH FOR THE WWE CRUISERWEIGHT CHAMPIONSHIP I'm a very big fan of Cruiserweights, & I never get disappointed watching them, especially in this match here. Chavo Guerrero nails the Frog Splash on Jimmy Wang Yang to get the win & become the new WWE Cruiserweight Champion. 5/10<br /><br />THIRD MATCH- FINLAY & LITTLE BASTARD VS. BOOGEYMAN & LITTLE BOOGEYMAN This was not really a wrestling match, it was more like a comedy match, despite not being a clear wrestling contest, it still entertained me with the funny antics. Finlay nails the Little Boogeyman with the Shillaegh to get the win. Boogeyman does not deserve to be on a PPV, & does not deserve to be in WWE. 4/10<br /><br />FOURTH MATCH- KANE VS. KING BOOKER W/ SHARMELL This was a surprisingly good match, I thought it would be mediocre, but it turned out into a real competitive wrestling contest. Hats off to both men, pulling a very entertaining match. Kane wins after a Chokeslam on King Booker. 6/10<br /><br />FIFTH MATCH- PAUL London & BRIAN KENDRICK {CHAMPIONS} VS. DEUCE & DOMINO W/ CHERRY FOR THE WWE TAG TEAM CHAMPIONSHIPS Not really that much of a good match, Deuce & Domino need more training to wrestle, & London & Kendrick are the only ones keeping this match fast paced. London & Kendrick retain their titles, after Kendrick gets a roll-up on one of the guys for the win. 4/10<br /><br />SIXTH MATCH- BOBBY LASHLEY {CHAMPION} VS. MR. KENNEDY FOR THE ECW CHAMPIONSHIP Mr. Kennedy attacks Lashley from behind, before the match starts. It was an okay match, but not really good. Lashley & Kennedy have a bit of chemistry, but not enough to pull a great match. Kennedy wins by DQ, after Lashley nails him with a chair, then assaults him with the chair all the way to the entrance area. Lashley still retains his title. 4/10<br /><br />SEVENTH MATCH- JOHN CENA & SHAWN MICHAELS VS. BATISTA & UNDERTAKER This is probably the greatest tag team match that I have ever seen. Hats off to all of these men {yes even Batista} for pulling off as close as a 5 star main event classic. All 4 of these men played their parts in the match very well, as this was a very great & entertaining tag team match. Batista turns his back on Undertaker spine-busting him, then leaving the ring, which prompts Michaels to nail Sweet Chin Music, then Cena to nail an F-U for the hard fought victory. 7/10<br /><br />I don't know why everyone says that this PPV is not good enough, or it is boring, I just don't get it. It is a great PPV which Smackdown always delivers. A great PPV indeed.<br /><br />Overall I'll give it 8/10 & a B+

Really? Obama kept the birther junk going for a long time before biting the bullet and providing his full birth certificate. That was bizarre. The Russian angle is incredible. Well the crux of the matter is that we see the world through different glasses. I think you are fact-free and you think I am fact-free. Round and round the mulberry bush, the monkey chased the weasel,

Using the light-front holographic model, we study the transverse momentum
dependent parton distributions (TMDs) for the case of pion. At leading twist,
the unpolarized parton distribution function $ f_{1\pi}(x,\bfk^{2}) $ and the
Boer-Mulders function $ h_{1\pi}^{\bot}(x,\bfk^{2}) $ are obtained for pion. We
calculate both the functions using the light-front holographic model with spin
improved wave function and compare the predicted results with available results
of other models. In order to provide inputs in predicting future experimental
data, a LO evolution is performed from model scale to experimental scale for
the case of unpolarized parton distribution function $ f_{1\pi}(x,\bfk^{2}) $.

We discuss the problem of finding the most favorable conditions for closing
the detection loophole in a test of local realism with a Bell inequality. For a
generic non-maximally entangled two-qubit state and two alternative measurement
bases we apply Hardy's proof of non-locality without inequality and derive an
Eberhard-like inequality. For an infinity of non-maximally entangled states we
find that it is possible to refute local realism by requiring perfect detection
efficiency for only one of the two measurements: the test is free from the
detection loophole for any value of the detection efficiency corresponding to
the other measurement. The maximum tolerable noise in a loophole-free test is
also evaluated.

In this paper, we obtain Groebner-Shirshov (non-commutative Gr\"obner) bases
for the braid groups in the Birman-Ko-Lee generators enriched by new ``Garside
word" $\delta$. It gives a new algorithm for getting the Birman-Ko-Lee Normal
Form in the braid groups, and thus a new algorithm for solving the word problem
in these groups.

We study the stability of a special form of D brane embedding which is
regarded as a bound state of D$_n$ and anti-D$_n$-brane embedded in a 10D
supergravity background which is dual to a confining gauge theory. For D5
branes with $U(1)$ flux, their bound state configuration can be regarded as the
baryonium vertex. For D branes of $n=6$ and 8 without the $U(1)$ flux, their
bound states have been used to introduce flavor quarks in the dual
supersymmetric Yang-Mills theory. In any case, it would be important to assure
that they are free from tachyon instability. For all these cases, we could show
their stability with respect to this point.

Very space savvy!!! Super to fit more than just soccer items.
The backpack is awesome!! Fits books and soccer stuff for our 6th grader who is on the soccer team. Big minus is that the zipper for the section where the ball is supposed to be gets stuck to the point that you cannot open it.

In this paper, we present LaSOT, a high-quality benchmark for Large-scale
Single Object Tracking. LaSOT consists of 1,400 sequences with more than 3.5M
frames in total. Each frame in these sequences is carefully and manually
annotated with a bounding box, making LaSOT the largest, to the best of our
knowledge, densely annotated tracking benchmark. The average video length of
LaSOT is more than 2,500 frames, and each sequence comprises various challenges
deriving from the wild where target objects may disappear and re-appear again
in the view. By releasing LaSOT, we expect to provide the community with a
large-scale dedicated benchmark with high quality for both the training of deep
trackers and the veritable evaluation of tracking algorithms. Moreover,
considering the close connections of visual appearance and natural language, we
enrich LaSOT by providing additional language specification, aiming at
encouraging the exploration of natural linguistic feature for tracking. A
thorough experimental evaluation of 35 tracking algorithms on LaSOT is
presented with detailed analysis, and the results demonstrate that there is
still a big room for improvements.

Don't buy the 2 GB Version
I've been told the 4 GB version runs a lot better and I wish I listened. I got the 2 GB with normal Windows 10 and once I booted up starting experienced problems upon startup. The issue is it constantly runs slow and when I even opened a web browser the RAM just capped immediately. I tried using YouTube and it barely ran at 480p and that was a chore for the little stick. The processor seemed to run ok and the computer to it's credit booted quickly. But once it got in it just seemed to lose that speed very fast. It even had trouble signing in, giving me time out errors or saying it couldn't pull up my pin to log in. The only positive is for a stick PC, the 32 GB eMMC was nice plus it could be expanded via SD card. The actual build is nice it's just too bad that the 2 GB version can't keep up. If you do get this I strongly recommend having the 4 GB version. I've heard it's much better.

We explore the rich and unique magnetic quantization of Si-doped graphene
defect systems with various concentrations and configurations using the
generalized tight-binding model. This model takes into account simultaneously
the non-uniform bond lengths, site energies and hopping integrals, and a
uniform perpendicular magnetic field (${B_z\hat z}$). The magnetic quantized
Landau levels (LLs) are classified into four different kinds based on the
probability distributions and oscillation modes. The main characteristics of
LLs are clearly reflected in the magneto-optical selection rules which cover
the dominating ${\Delta\,n=|n^v-n^c|=0}$, the coexistent ${\Delta\,n=0}$ $\&$
${\Delta\,n=1}$, and the specific ${\Delta\,n=1}$. These rules for inter-LLs
excitations come from the non-equivalence or equivalence of the A$_i$ and B$_i$
sublattices in a supercell.

In this paper, a round-table group optimization (RTGO) algorithm is
presented. RTGO is a simple metaheuristic framework using the insights of
research on group creativity. In a cooperative group, the agents work in
iterative sessions to search innovative ideas in a common problem landscape.
Each agent has one base idea stored in its individual memory, and one social
idea fed by a round-table group support mechanism in each session. The idea
combination and improvement processes are respectively realized by using a
recombination search (XS) strategy and a local search (LS) strategy, to build
on the base and social ideas. RTGO is then implemented for solving two
difficult sequencing problems, i.e., the flowshop scheduling problem and the
quadratic assignment problem. The domain-specific LS strategies are adopted
from existing algorithms, whereas a general XS class, called socially biased
combination (SBX), is realized in a modular form. The performance of RTGO is
then evaluated on commonly-used benchmark datasets. Good performance on
different problems can be achieved by RTGO using appropriate SBX operators.
Furthermore, RTGO is able to outperform some existing methods, including
methods using the same LS strategies.

We present a simple analysis of the force noise associated with the
mechanical damping of the motion of a test body surrounded by a large volume of
rarefied gas. The calculation is performed considering the momentum imparted by
inelastic collisions against the sides of a cubic test mass, and for other
geometries for which the force noise could be an experimental limitation. In
addition to arriving at an accurated estimate, by two alternative methods, we
discuss the limits of the applicability of this analysis to realistic
experimental configurations in which a test body is surrounded by residual gas
inside an enclosure that is only slightly larger than the test body itself.

Between 1937 and 1939, Twentieth Century-Fox made a ton of Mr. Moto films. However, towards the end of the series, it was obvious that the studio had "jumped the shark", so to speak. This phrase indicates that a TV show has passed its prime and the executives in charge decided to invigorate the show by fundamentally changing the formula. For example, with "The Brady Bunch" they introduced the annoying 'Cousin Oliver' and with "Family Ties" they introduced a freak baby who grew up six years in only one season! With the Moto films, they'd jumped the shark by introducing comic relief because they thought that these intelligent films needed to be re-tooled. In the previous film, Warren Hymer played an annoying wrestler. And, in this film the character Archibald Featherstone appears. Featherstone might just be one of the most annoying examples of comic relief ever, as you kept hoping someone (preferably Moto) would kill him just to shut him up!! Although he's supposed to work for the famed Scotland Yard, he shows all the intelligence and acumen of a brain damaged turnip. Again and again, his scenes were boorish and unnecessary and Peter Lorre just looks pained as he stands there and watches this buffoon "act". It's so bad that it truly destroys what COULD have been one of the better Moto films due to its clever plot.<br /><br />As for the plot, the crown of the Queen of Sheba is discovered in the opening scene. Moto, now more of an international policeman than the amoral character he originally was, is on hand to protect the precious item from being stolen. In a great twist, several thieves all try to steal the crown independently of each other.<br /><br />Overall, the film is watchable but is also ample evidence that the Moto series should have ended here. With WWII approaching, the films couldn't have survived much longer anyway, as having a sympathetic Japanese leading character simply wouldn't have been accepted in the US or in allied countries.

Pre-trained language representation models, such as BERT, capture a general
language representation from large-scale corpora, but lack domain-specific
knowledge. When reading a domain text, experts make inferences with relevant
knowledge. For machines to achieve this capability, we propose a
knowledge-enabled language representation model (K-BERT) with knowledge graphs
(KGs), in which triples are injected into the sentences as domain knowledge.
However, too much knowledge incorporation may divert the sentence from its
correct meaning, which is called knowledge noise (KN) issue. To overcome KN,
K-BERT introduces soft-position and visible matrix to limit the impact of
knowledge. K-BERT can easily inject domain knowledge into the models by
equipped with a KG without pre-training by-self because it is capable of
loading model parameters from the pre-trained BERT. Our investigation reveals
promising results in twelve NLP tasks. Especially in domain-specific tasks
(including finance, law, and medicine), K-BERT significantly outperforms BERT,
which demonstrates that K-BERT is an excellent choice for solving the
knowledge-driven problems that require experts.

ObjectiveTranscranial magnetic stimulation (TMS) can modulate brain function via an electric field (E-field) induced in a region of interest (ROI) in the brain. The ROI E-field can be computationally maximized and set to match a specific reference using individualized head models to find the optimal coil placement and stimulus intensity. However, the available software lacks many practical features for prospective planning of TMS interventions and retrospective evaluation of the experimental targeting accuracy.
ApproachThe TMS targeting and analysis pipeline (TAP) software uses an MRI/fMRI-derived brain target to optimize coil placement considering experimental parameters such as the subjects hair thickness and coil placement restrictions. The coil placement optimization is implemented in SimNIBS 3.2, for which an additional graphical user interface (TargetingNavigator) is provided to visualize and adjust procedural parameters. The coil optimization process also computes the E-field at the target, allowing the selection of the TMS device intensity setting to achieve a specific E-field strength. The optimized coil placement information is prepared for neuronavigation software, which supports targeting during the TMS procedure. The neuronavigation system can record the coil placement during the experiment, and these data can be processed in TAP to quantify the accuracy of the experimental TMS coil placement and induced E-field.
Main resultsTAP was demonstrated in a study consisting of three repetitive TMS sessions in five subjects. TMS was delivered by an experienced operator under neuronavigation with the computationally optimized coil placement. Analysis of the experimental accuracy from the recorded neuronavigation data indicated coil location and orientation deviations up to about 2 mm and 2{degrees}, respectively, resulting in an 8% median decrease in the target E-field magnitude compared to the optimal placement.
SignificanceTAP supports navigated TMS with a variety of features for rigorous and reproducible stimulation delivery, including planning and evaluation of coil placement and intensity selection for E-field-based dosing.

beautiful love story
I really loved this story. I didn't even realize until I was finished that it was loosely based on real events and real people. This was a true love story during a time that saw too many obstacles. I loved the characters and the sense of place. Well done!

What people fail to understand about this movie is that it isn't a beginning, middle, and end, it is just the conclusion of a 26 episode long TV series. So remember that when you all talk about how the world wasn't explored enough. That was all done in the TV show.<br /><br />As great and stunning as the visuals are, I think the ***SPOILERS*** argument between Lian-Chu and Gwizdo near the end of the film was what really made me love this movie. Seeing characters I had followed through 26 episodes fight like that was agonizing, and seeing Gwizdo walking sadly off by himself amidst the floating ruins while Lian-Chu sharpened his blade was almost tear-jerking. <br /><br />Then we got a total contrast with Lian-Chu fighting these insanely awesome dragons (Which had been featured before in the series) while Gwizdo is babbling insanely and indirectly threatening to kill Zoe. *Shudder* I'm surprised that this particular scene hasn't been mentioned more in the warnings. Any kid that has a lick of sense will be able to see that Gwizdo wasn't himself and was fully intent on strangling that little girl. It was enough to bother me, and I'm 15.<br /><br />The world is amazing, the plot is a lot better than most multi-million blockbusters, and it was a nice way to see some of my favorite characters go. Check it out. :)

Not as shown! But still pretty awesome!!
The actual hair of this model isn’t the hair you’ll receive but it is still cool! I wore it for 3 months and deep conditioned it regularly. I have now retired it until I choose to use it again and it’s thinner but the hair is wavy and beautiful so I really don’t have to blow dry it! Overall I’d buy it again!!!!

In this article, we introduce a conditional marginal model for longitudinal
data, in which the residuals form a martingale difference sequence. This model
allows us to consider a rich class of estimating equations, which contains
several estimating equations proposed in the literature. A particular sequence
of estimating equations in this class contains a random matrix
$\mathcal{R}_{i-1}^*(\beta)$, as a replacement for the ``true'' conditional
correlation matrix of the $i$-th individual. Using the approach of [12], we
identify some sufficient conditions under which this particular sequence of
equations is asymptotically optimal (in our class). In the second part of the
article, we identify a second set of conditions, under which we prove the
existence and strong consistency of a sequence of estimators of $\beta$,
defined as roots of estimation equations which are martingale transforms (in
particular, roots of the sequence of asymptotically optimal equations).

Think of it as an extreme form of detention without trial. Without commenting and taking a side on the US Foreign Policy, the process of Extraordinary Rendition involves taking persons suspected of terrorist activities to a foreign country, an opposite to an extradition if you wish, to a place where torture is not a crime but a means to illicit information. Instead of staining your soil with blood of potentially innocent parties, you do so on foreign land where such tactics are accepted interrogation techniques.<br /><br />Naturally, given the severity of the tactics and attempts at breaking down a person, sometimes you would get what you want once you pass the resistance, or get nothing, or worst of all, get a confession just because the mind has been broken to the point that the subject will agree to whatever you say. It's an ugly process, and what better way to do it when you're the champion human rights, giving the nod to use whatever means necessary in the name of protecting more lives, in an age where information is key to the battle against terror, and doing so in a country where probably the rights record is questionable.<br /><br />Rendition is this year's Syriana, though in the run up to the new year we do have a number of political thriller contenders to take that crown, with Rendition first of all, followed by the Robert Redford movie Lions for Lambs, starring Tom Cruise and Meryl Streep (again, though now on the other side of the fence), and The Kingdom with Jamie Foxx and Jennifer Garner, though this one would probably turn out to be more action driven. Directed by Gavin Hood, who did Tsotsi and will be helming the new Wolverine spin off, Rendition is a decent thriller with a top notch cast, in a narrative that has been proved quite popular these days - the split, which provides for some ample differential perspectives to be presented through an ensemble cast.<br /><br />Anwar El-Ibrahimi (Omar Metwally), a chemical engineer, gets renditioned en route to going home under the orders of CIA top brass Corrine Whitman (Meryl Streep). At a detention facility outside the US, Jake Gyllenhaal's CIA analyst Douglas Freeman (oh so prophetic) embarks on his very first interrogation session, no doubt being thrust into a position that he didn't sign up for. Back home, a very pregnant Reese Whitherspoon searches frantically for answers to her husband's disappearance, and sought after an ex-flame Alan Smith's (Peter Sarsgaard) assistance, since he's working for Senator Hawkins (Alan Arkin). Throw in J.K. Sinmmons, a terrorist plot investigation and a budding forbidden love story between Fatima (Zineb Oukach) and Khalid (Moa Khouas), you have quite a bit going on in a busy picture.<br /><br />Given a number of casts, locations, timelines and the likes, Rendition wasn't confusing at all, and it plays out with deft handling of the material, never quick to judge, presenting ideas and thoughts from both sides of the equation. Every character has their own agenda, and the unveiling of this agenda engages enough not to bore nor to confuse you. And the best part of it all is how, very truly, they bow down to self-preservation in different forms, and ultimately, in various lose-lose situations unfortunately. It kept you guessing as well - did he or didn't he, and constantly played with your mind as to whether Anwar deserved what he's getting. It utilized one extremely smart sleight of hand which I didn't see coming until it's too late (so there goes the credit), though it did succumb to the usual stereotyping of terrorist militants, and without spending much time in depth to explore their motivations. <br /><br />Perhaps it didn't find a need to, given so many movies out there already touching base on this issue (Paradise Now, Day Night Day Night, Syriana even). While it turned out to be rather one-dimensional (personal tragedy to strapping of bombs to become a suicide bomber), I felt Rendition did right in not providing any saccharine sweet ending, that this fight against negative, destructive ideology, isn't something that can be addressed in a two hour movie, and I'm glad it steered clear such fairy tale implausibilities. <br /><br />What we have instead is a well crafted tale that sets its gun sights on the issue of Rendition, and probably capable enough to spark discussion once the lights come on, on which camp you belong to - do you support inflicting severe pain in interrogation? Yes or No? This is the quintessential question of our time. Yes or No? (OK, I'm already geared for Lions for Lambs)!

In this paper, we exploit the benefits of the deep learning approach to
design an efficient system of Amazigh handwritten recognition. Indeed, this
approach has proved a greater efficiency in the various domains, especially
recognition tasks. However, to take full advantage of this approach it's
necessary to construct an adequate dataset of training and testing that
represent faithfully the concerned problem. To this end, we have prepared our
dataset of 102 writers each one contains 33 characters of IRCAM-Tifinagh.
Inspired by the MNIST database, the set of characters is size-normalized and
centered in a fixed-size image. The resulting is a grey level image of size
28x28, where the black color is the non-color of the character. The number of
images produced after this preprocessing step is 3,366.

We study the combined effect of delayed Raman response and bit pattern
randomness on pulse propagation in massive multichannel optical fiber
communication systems. The propagation is described by a perturbed stochastic
nonlinear Schr\"odinger equation, which takes into account changes in pulse
amplitude and frequency as well as emission of continuous radiation. We perform
extensive numerical simulations with the model, and analyze the dynamics of the
frequency moments, the bit-error-rate, and the mutual distribution of amplitude
and position. The results of our numerical simulations are in good agreement
with theoretical predictions based on the adiabatic perturbation approach.

Understanding the dynamics of international politics is important yet
challenging for civilians. In this work, we explore unsupervised neural models
to infer relations between nations from news articles. We extend existing
models by incorporating shallow linguistics information and propose a new
automatic evaluation metric that aligns relationship dynamics with manually
annotated key events. As understanding international relations requires
carefully analyzing complex relationships, we conduct in-person human
evaluations with three groups of participants. Overall, humans prefer the
outputs of our model and give insightful feedback that suggests future
directions for human-centered models. Furthermore, our model reveals
interesting regional differences in news coverage. For instance, with respect
to US-China relations, Singaporean media focus more on "strengthening" and
"purchasing", while US media focus more on "criticizing" and "denouncing".

I must confess that I don't remember this film very well. But, certainly I liked it. I think it was the best adaptation from Burroughs novel, really. And of course it's one of the best movie from Christopher Lambert.<br /><br />A good movie about Tarzan, as cult as the ones with Weissmuller.

At Christmas time, in spite of my misgivings, I took the tree out and added another string of lights (it comes with a very nice clear colored miniature light string already on the tree), a golden garland, some tinsel, and a couple dozen ornaments, and I was really surprised at how beautiful this little tree is.

Hunting is for men who a lacking in any number of areas. The planet is in massive decline and animal and plant populations are being decimated. Humans truly are viruses that consume without consideration and it will be our undoing. As a small but huge example, the honey bees are in decline due to chemical/pesticides and if the bees where to go extinct, the fruit and vegetable industry would collapse leading to mass starvation. The root cause of all the world's ills is overpopulation. Stop having children indiscriminately.

Although infinite cylinders are not astrophysical entities, it is possible to
learn a great deal about the basic qualitative features of generation of
gravitational waves and the behavior of the matter conforming such shells in
the limits of very small radius. We describe the analytical model using kinetic
theory for the matter and the junction conditions through the shell to obtain
its equation of motion. The nature of the static solutions are analyzed, both
for a single shell as well as for two concentric shells. In this second case,
for a time dependent external shell, we integrate numerically the equation of
motion for several values of the constants of the system. Also, a brief
description in terms of the Komar mass is given to account for the
gravitational wave energy emitted by the system.

We review current understanding of star formation, outlining an overall
theoretical framework and the observations that motivate it. A conception of
star formation has emerged in which turbulence plays a dual role, both creating
overdensities to initiate gravitational contraction or collapse, and countering
the effects of gravity in these overdense regions. The key dynamical processes
involved in star formation -- turbulence, magnetic fields, and self-gravity --
are highly nonlinear and multidimensional. Physical arguments are used to
identify and explain the features and scalings involved in star formation, and
results from numerical simulations are used to quantify these effects. We
divide star formation into large-scale and small-scale regimes and review each
in turn. Large scales range from galaxies to giant molecular clouds (GMCs) and
their substructures. Important problems include how GMCs form and evolve, what
determines the star formation rate (SFR), and what determines the initial mass
function (IMF). Small scales range from dense cores to the protostellar systems
they beget. We discuss formation of both low- and high-mass stars, including
ongoing accretion. The development of winds and outflows is increasingly well
understood, as are the mechanisms governing angular momentum transport in
disks. Although outstanding questions remain, the framework is now in place to
build a comprehensive theory of star formation that will be tested by the next
generation of telescopes.

Given a positive function $F$ on $S^n$ which satisfies a convexity condition,
we define the $r$-th anisotropic mean curvature function $H^F_r$ for
hypersurfaces in $\mathbb{R}^{n+1}$ which is a generalization of the usual
$r$-th mean curvature function. Let $X:M\to \mathbb{R}^{n+1}$ be an
$n$-dimensional closed hypersurface with $H^F_{r+1}=$constant, for some $r$
with $0\leq r\leq n-1$, which is a critical point for a variational problem. We
show that $X(M)$ is stable if and only if $X(M)$ is the Wulff shape.

We show that the convergence behavior of the many-body numerical
diagonalization scheme for strongly interacting bosons in a trap can be
significantly improved by the Lee-Suzuki method adapted from nuclear physics:
One can construct an effective interaction that acts in a space much smaller
than the original Hilbert space. In particular for short-ranged forces and
strong correlations, the method offers a good estimate of the energy and the
excitation spectrum, at a computational cost several orders of magnitude
smaller than that required by the standard method.

We study the evolution of networks when the creation and decay of links are
based on the position of nodes in the network measured by their centrality. We
show that the same network dynamics arises under various centrality measures,
and solve analytically the network evolution. During the complete evolution,
the network is characterized by nestedness: the neighbourhood of a node is
contained in the neighbourhood of the nodes with larger degree. We find a
discontinuous transition in the network density between hierarchical and
homogeneous networks, depending on the rate of link decay. We also show that
this evolution mechanism leads to double power-law degree distributions, with
interrelated exponents.

*Contains spoilers due to me having to describe some film techniques, so read at your own risk!*<br /><br />I loved this film. The use of tinting in some of the scenes makes it seem like an old photograph come to life. I also enjoyed the projection of people on a back screen. For instance, in one scene, Leopold calls his wife and she is projected behind him rather than in a typical split screen. Her face is huge in the back and Leo's is in the foreground.<br /><br />One of the best uses of this is when the young boys kill the Ravensteins on the train, a scene shot in an almost political poster style, with facial close ups. It reminded me of Battleship Potemkin, that intense constant style coupled with the spray of red to convey tons of horror without much gore. Same with the scene when Katharina finds her father dead in the bathtub...you can only see the red water on the side. It is one of the things I love about Von Trier, his understatement of horror, which ends up making it all the more creepy.<br /><br />The use of text in the film was unique, like when Leo's character is pushed by the word, "Werewolf." I have never seen anything like that in a film.<br /><br />The use of black comedy in this film was well done. Ernst-Hugo Järegård is great as Leo's uncle. It brings up the snickers I got from his role in the Kingdom (Riget.) This humor makes the plotline of absurd anal retentiveness of train conductors against the terrible backdrop of WW2 and all the chaos, easier to take. It reminds me of Riget in the way the hospital administrator is trying to maintain a normalcy at the end of part one when everything is going crazy. It shows that some people are truly oblivious to the awful things happening around them. Yet some people, like Leo, are tuned in, but do nothing positive about it.<br /><br />The voice over, done expertly well by Max von Sydow, is amusing too. It draws you into the story and makes you jump into Leo's head, which at times is a scary place to be.<br /><br />The movie brings up the point that one is a coward if they don't choose a side. I see the same idea used in Dancer in the Dark, where Bjork's character doesn't speak up for herself and ends up being her own destruction. Actually, at one time, Von Trier seemed anti-woman to me, by making Breaking the Waves and Dancer, but now I know his male characters don't fare well either! I found myself at the same place during the end of Dancer, when you seriously want the main character to rethink their actions, but of course, they never do!

I think you missed the part where Canada's high tech CEOs think Trump will be good for foreign recruitment here in Canada. A better destination for the best and the brightest, whether they wear a Niquab or not.
That might mean more competition in the short run for Canadian High Tech Grads, though if we become a major hub of activity that won't be an issue.

Spatio-temporal optical vortices (STOVs) are a new type of optical orbital
angular momentum (OAM) with optical phase circulation in space-time. In prior
work [N. Jhajj et al., Phys. Rev X 6, 031037 (2016)], we demonstrated that a
STOV is a universal structure emerging from the arrest of self-focusing
collapse leading to nonlinear self-guiding in material media. Here, we
demonstrate linear generation and propagation in free space of STOV-carrying
pulses. Our measurements and simulations demonstrate STOV mediation of
space-time energy flow within the pulse and conservation of OAM in space-time.
Single-shot amplitude and phase images of STOVs are taken using a new
diagnostic, transient grating single-shot supercontinuum spectral
interferometry (TG-SSSI).

Conducting a manual evaluation is considered an essential part of summary
evaluation methodology. Traditionally, the Pyramid protocol, which exhaustively
compares system summaries to references, has been perceived as very reliable,
providing objective scores. Yet, due to the high cost of the Pyramid method and
the required expertise, researchers resorted to cheaper and less thorough
manual evaluation methods, such as Responsiveness and pairwise comparison,
attainable via crowdsourcing. We revisit the Pyramid approach, proposing a
lightweight sampling-based version that is crowdsourcable. We analyze the
performance of our method in comparison to original expert-based Pyramid
evaluations, showing higher correlation relative to the common Responsiveness
method. We release our crowdsourced Summary-Content-Units, along with all
crowdsourcing scripts, for future evaluations.

A poor quality product.
Very disappointed with product. The overall car quality was cheap, but the worst was that Minnie did not really fit into the car as a rider. She is a hard plastic figure that stands up and falls down if the car moves. Do not recommend. This is not the Fisher-Price quality that one expects.

We discuss the physics of large impact parameter interactions at the LHC:
ultraperipheral collisions (UPCs). The dominant processes in UPCs are
photon-nucleon (nucleus) interactions. The current LHC detector configurations
can explore small $x$ hard phenomena with nuclei and nucleons at photon-nucleon
center-of-mass energies above 1 TeV, extending the $x$ range of HERA by a
factor of ten. In particular, it will be possible to probe diffractive and
inclusive parton densities in nuclei using several processes. The interaction
of small dipoles with protons and nuclei can be investigated in elastic and
quasi-elastic $J/\psi$ and $\Upsilon$ production as well as in high $t$
$\rho^0$ production accompanied by a rapidity gap. Several of these phenomena
provide clean signatures of the onset of the new high gluon density QCD regime.
The LHC is in the kinematic range where nonlinear effects are several times
larger than at HERA. Two-photon processes in UPCs are also studied. In
addition, while UPCs play a role in limiting the maximum beam luminosity, they
can also be used a luminosity monitor by measuring mutual electromagnetic
dissociation of the beam nuclei. We also review similar studies at HERA and
RHIC as well as describe the potential use of the LHC detectors for UPC
measurements.

Great for what it's supposed to do
Great for what it's supposed to do, however, the sleep/wake button is extremely hard to press down and the removal process of the case of rather annoying and difficult. In addition, DO NOT buy this case if you're looking to use a phone skin on your device. This product will ruin the skin because of how hard it is to put on the case. Would only recommend to those who don't care about a hard clicking sleep button and who don't run a skin. Otherwise, just wait for the new Dbrand grip case.

The Alaska LNG pipeline was already dead long before this, despite Gov Talker's best intentions, because neither the producers nor the market have any interest in it. As for the oil pipeline, its problem is a lack of product flowing through it and not the pipe itself. Hopefully that will be corrected soon thanks to recent discoveries and an Alaskan oil friendly president in the white house.

I would have to say that in general Barbie Movies have impressed me. I have a 5 year old Barbie fanatic niece and she watches them all the time so needless to say I have seen quite a lot of Barbie these holidays, but I am not sick of them.<br /><br />This film, visually, has a lot to offer, especially the backgrounds, and the animation of the characters has improved with each new movie. One thing I noticed in particular was a vast improvement in the animation of Barbie's hair in this film. It has a lovely range of excerpts from classical music and I think that this is great, as it exposes a new generation to the classics. This film is well worth ago, especially if you have young relievers. They will be entertained for hours!

We report a new multicanonical Monte Carlo algorithm to obtain the density of
states for physical systems with continuous state variables in statistical
mechanics. Our algorithm is able to obtain a closed-form expression for the
density of states expressed in a chosen basis set, instead of a numerical array
of finite resolution as in previous variants of this class of MC methods such
as the multicanonical sampling and Wang-Landau sampling. This is enabled by
storing the visited states directly and avoiding the explicit collection of a
histogram. This practice also has the advantage of avoiding undesirable
artificial errors caused by the discretization and binning of continuous state
variables. Our results show that this scheme is capable of obtaining converged
results with a much reduced number of Monte Carlo steps, leading to a
significant speedup over existing algorithms.

The current paper is devoted to the study of existence and non-existence of
transition fronts for two species competition lattice system in random media,
and explore the influence of randomness of the media on the wave profiles and
wave speeds of such transition fronts. We first establish comparison principle
for sub-solutions and super-solutions of the related cooperative system. Next,
under some proper assumptions, we construct appropriate sub-solutions and
super-solutions for the cooperative system. Finally, we show that random
transition fronts exist if their least mean speed is greater than an explicit
threshold and there is no random transition front with least mean speed less
than the threshold.

In this paper, we consider flow simulation in highly heterogeneous media that
has many practical applications in industry. To enhance mass conservation, we
write the elliptic problem in a mixed formulation and introduce a robust
two-grid preconditioner to seek the solution. We first need to transform the
indefinite saddle problem to a positive definite problem by preprocessing
steps. The preconditioner consists of a local smoother and a coarse
preconditioner. For the coarse preconditioner, we design an adaptive spectral
coarse space motivated by the GMsFEM (Generalized Multiscale Finite Element
Method). We test our preconditioner for both Darcy flow and two phase flow and
transport simulation in highly heterogeneous porous media. Numerical results
show that the proposed preconditioner is highly robust and efficient.
|
We analyze the geometry of rational p-division points in degenerating
families of elliptic curves in characteristic p. We classify the possible
Kodaira symbols and determine for the Igusa moduli problem the reduction type
of the universal curve. Special attention is paid to characteristic 2 and 3
where wild ramification and stacky phenomena show up.

We present an analysis of the small-to-intermediate scale clustering of
samples of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey and
the 2dF-SDSS LRG and QSO (2SLAQ) survey carefully matched to have the same
rest-frame colours and luminosity. We study the spatial two-point
auto-correlation function in both redshift-space and real-space of a combined
sample of over 10,000 LRGs, which represent the most massive galaxies in the
universe with stellar masses > 10^11 h^-1 M_sun and space densities 10^-4 h^-3
Mpc^-3. We find no significant evolution in the amplitude r_0 of the
correlation function with redshift, but do see a slight decrease in the slope
with increasing redshift over 0.19 < z < 0.55 and scales of 0.32 < r < 32 h^-1
Mpc. We compare our measurements with the predicted evolution of dark matter
clustering and use the halo model to interpret our results. We find that our
clustering measurements are inconsistent (>99.9% significance) with a passive
model whereby the LRGs do not merge with one another; a model with a merger
rate of 7.5 +/- 2.3% from z = 0.55 to z = 0.19 (i.e. an average rate of 2.4%
Gyr^-1) provides a better fit to our observations. Our clustering and number
density measurements are consistent with the hypothesis that the merged LRGs
were originally central galaxies in different haloes which, following the
merger of these haloes, merged to create a single Brightest Cluster Galaxy. In
addition, we show that the small-scale clustering signal constrains the scatter
in halo merger histories. When combined with measurements of the luminosity
function, our results suggest that this scatter is sub-Poisson. While this is a
generic prediction of hierarchical models, it has not been tested before.

We present an approach for reconfiguration of dynamic visual sensor networks
with deep reinforcement learning (RL). Our RL agent uses a modified
asynchronous advantage actor-critic framework and the recently proposed
Relational Network module at the foundation of its network architecture. To
address the issue of sample inefficiency in current approaches to model-free
reinforcement learning, we train our system in an abstract simulation
environment that represents inputs from a dynamic scene. Our system is
validated using inputs from a real-world scenario and preexisting object
detection and tracking algorithms.

Web search engines retrieve a vast amount of information for a given search
query. But the user needs only trustworthy and high-quality information from
this vast retrieved data. The response time of the search engine must be a
minimum value in order to satisfy the user. An optimum level of response time
should be maintained even when the system is overloaded. This paper proposes an
optimal Load Shedding algorithm which is used to handle overload conditions in
real-time data stream applications and is adapted to the Information Retrieval
System of a web search engine. Experiment results show that the proposed
algorithm enables a web search engine to provide trustworthy search results to
the user within an optimum response time, even during overload conditions.

Should have listened to other reviews about quality
Beautiful artwork, but should have listened to other reviewers about the quality. Out of the box, my cards were peeling and scuffed. Bent cards and flaky borders. A ruined opportunity for a beautiful deck. Returned as damaged. Will not reorder. Absolutely hate the Hermit card! So tiny... can't hardly see him.

I totally agree with the review by a reviewer of Variety that the film is never quite as funny, lively or insightful about the creative process as its premise would seem to warrant. Narratively it is messy and the lighting is really problematic. If the film is supposed to be character-driven the poor lighting doesn't enhance the acting and it is sometimes difficult to observe the facial expressions of the actors. Many non-South Africans will have difficulty in following the spoken English in the film and some of the local humor will be lost in the process. I watched the film at the Cape Town World Cinema festival last year. Comments and reactions to the film ranged from unwatchable and sloppy to a welcome departure from the films about our painful past. Unfortunately Bunny Chow won't be remembered as one of the bright lights of the South African New Wave, but some of the remarkable films about our apartheid history will indeed be rated among our best in our 110 year old film history. Not surprisingly the film disappeared from cinemas in Cape Town only two weeks after its release and from most of the cinemas in Durban and Gauteng. It has clearly limited appeal among South African audiences.

In this note cosmological models coming out of the String Field Theory (SFT)
in application to the Dark Energy are reviewed. A way of constructing solutions
in the case of linear models is outlined, cosmological perturbations and
observational evidences of such models are explored. We explicitly demonstrate
the stability of the system at the linear order in the most typical
configuration.

Label manipulation attacks are a subclass of data poisoning attacks in
adversarial machine learning used against different applications, such as
malware detection. These types of attacks represent a serious threat to
detection systems in environments having high noise rate or uncertainty, such
as complex networks and Internet of Thing (IoT). Recent work in the literature
has suggested using the $K$-Nearest Neighboring (KNN) algorithm to defend
against such attacks. However, such an approach can suffer from low to wrong
detection accuracy. In this paper, we design an architecture to tackle the
Android malware detection problem in IoT systems. We develop an attack
mechanism based on Silhouette clustering method, modified for mobile Android
platforms. We proposed two Convolutional Neural Network (CNN)-type deep
learning algorithms against this \emph{Silhouette Clustering-based Label
Flipping Attack (SCLFA)}. We show the effectiveness of these two defense
algorithms - \emph{Label-based Semi-supervised Defense (LSD)} and
\emph{clustering-based Semi-supervised Defense (CSD)} - in correcting labels
being attacked. We evaluate the performance of the proposed algorithms by
varying the various machine learning parameters on three Android datasets:
Drebin, Contagio, and Genome and three types of features: API, intent, and
permission. Our evaluation shows that using random forest feature selection and
varying ratios of features can result in an improvement of up to 19\% accuracy
when compared with the state-of-the-art method in the literature.

We construct a cosmological toy model based on a Finslerian structure of
space-time. In particular, we are interested in a specific Finslerian Lorentz
violating theory based on a curved version of Cohen and Glashow's Very Special
Relativity. The osculation of a Finslerian manifold to a Riemannian leads to
the limit of Relativistic Cosmology, for a specified observer. A modified flat
FRW cosmology is produced. The analogue of a zero energy particle unfolds some
special properties of the dynamics. The kinematical equations of motion are
affected by local anisotropies. Seeds of Lorentz Violations may trigger density
inhomogeneities to the cosmological fluid.

We have run two completely independent weak lensing analysis pipelines on a
set of realistic simulated images of a massive galaxy cluster with a singular
isothermal sphere profile (galaxy velocity dispersion sigma_v=1250 km/ sec).
The suite of images was constructed using the simulation tools developed by the
Dark Energy Survey. We find that both weak lensing pipelines can accurately
recover the velocity dispersion of our simulated clusters, suggesting that
current weak lensing tools are accurate enough for measuring the shear profile
of massive clusters in upcoming large photometric surveys. We also demonstrate
how choices of some cuts influence the final shear profile and sigma_v
measurement. Analogously to the STEP program, we make all of these cluster
simulation images publically available for other groups to analyze through
their own weak lensing pipelines.

The Dirac theory in the Euclidean Taub-NUT space gives rise to a large
collection of conserved operators associated to genuine or hidden symmetries.
They are involved in interesting algebraic structures as dynamical algebras or
even infinite-dimensional algebras or superalgebras. One presents here the
infinite-dimensional superalgebra specific to the Dirac theory in manifolds
carrying the Gross-Perry-Sorkin monopole. It is shown that there exists an
infinite-dimensional superalgebra that can be seen as a twisted loop
superalgebra.

The transition to turbulence in Taylor-Couette flow often occurs via a
sequence of supercritical bifurcations to progressively more complex, yet
stable, flows. We describe a subcritical laminar-turbulent transition in the
counter-rotating regime mediated by an unstable intermediate state in a system
with an axial aspect ratio of $\Gamma=5.26$ and a radius ratio of $\eta=0.905$.
In this regime, flow visualization experiments and numerical simulations
indicate the intermediate state corresponds to an aperiodic flow featuring
interpenetrating spirals. Furthermore, the reverse transition out of turbulence
leads first to the same intermediate state, which is now stable, before
returning to an azimuthally-symmetric laminar flow. Time-resolved tomographic
particle image velocimetry is used to characterize the experimental flows;
these measurements compare favorably to direct numerical simulations with axial
boundary conditions matching those of the experiments.

In 1936, Stanislaw Ja\'skowski gave a construction of an interesting sequence
of what he called "matrices", which we would today call "finite Heyting
Algebras". He then gave a very brief sketch of a proof that if a propositional
formula holds in each of these algebras then it is provable in intuitionistic
propositional logic (IPL). The sketch just describes a certain normal form for
propositional formulas and gives a very terse outline of an inductive argument
showing that an unprovable formula in the normal form can be refuted in one of
the algebras. Unfortunately, it is far from clear how to recover a complete
proof from this sketch. In the early 1950s, Gene F. Rose gave a detailed proof
of Ja\'skowski's result, still using the notion of matrix rather than Heyting
algebra, based on a normal form that is more restrictive than the one that
Ja\'skowski proposed. However, Rose's paper refers to his thesis for additional
details, particularly concerning the normal form.
This note gives a proof of Ja\'skowski's result using modern terminology and
a normal form more like Ja\'skowski's. We also prove a semantic property of the
normal form enabling us to give an alternative proof of completeness of IPL for
the Heyting algebra semantics. We outline a decision procedure for IPL based on
our proofs and illustrate it in action on some simple examples.

Estimation is the computational task of recovering a hidden parameter $x$
associated with a distribution $D_x$, given a measurement $y$ sampled from the
distribution. High dimensional estimation problems arise naturally in
statistics, machine learning, and complexity theory.
Many high dimensional estimation problems can be formulated as systems of
polynomial equations and inequalities, and thus give rise to natural
probability distributions over polynomial systems. Sum-of-squares proofs
provide a powerful framework to reason about polynomial systems, and further
there exist efficient algorithms to search for low-degree sum-of-squares
proofs.
Understanding and characterizing the power of sum-of-squares proofs for
estimation problems has been a subject of intense study in recent years. On one
hand, there is a growing body of work utilizing sum-of-squares proofs for
recovering solutions to polynomial systems when the system is feasible. On the
other hand, a general technique referred to as pseudocalibration has been
developed towards showing lower bounds on the degree of sum-of-squares proofs.
Finally, the existence of sum-of-squares refutations of a polynomial system has
been shown to be intimately connected to the existence of spectral algorithms.
In this article we survey these developments.

We associate with every Renner monoid $R$ a \emph{generic Hecke algebra}
$\H(R)$ over $\mathbb{Z}[q]$ which is a deformation of the monoid
$\mathbb{Z}$-algebra of $R$. If $M$ is a finite reductive monoid with Borel
subgroup $B$ and associated Renner monoid $R$, then we obtain the associated
Iwahori-Hecke algebra $\H(M,B)$ by specialising $q$ in $\H(R)$ and tensoring by
$\mathbb{C}$ over $\mathbb{Z}$, as in the classical case of finite algebraic
groups. This answers positively to a long-standing question of L. Solomon.

Blank Check is a movie that I saw on TV one day and like most movies they air on TV Blank Check wasn't that good. First of all no one I have ever met has seen Blank Check and that includes people that grew up in the 90s. Also Blank Check won't be remembered in the 00s either simply due to the fact that it will be overshadowed by pixar's films. I wouldn't call Blank Check a bad film but its not really entertaining either. (Or at least it isn't to anyone over the age of 6) Blank Check isn't a entertaining film because nothing about it is original. Everything just makes you go "what haven't I seen this before?" Blank Check rips off and tries to cash in on everything from Richie Rich to Home Alone (Which strangely enough both have Macaulay Culkin in it) Blank Check isn't a bad movie, but it deserves to fade into obscurity.

We study the stability and the modes of non -- isothermal coronal loop models
with different intensity values of the equilibrium twisted magnetic field.We
use an energy principle obtained via non -- equilibrium thermodynamic
arguments. The principle is expressed in terms of Hermitian operators and
allows to consider together the coupled system of equations: the balance of
energy equation and the equation of motion, to obtain modes and eigenmodes in a
spectrum ranging from short to long--wavelength disturbances without having to
use weak varying approximations of the equilibrium parameters. Long--wavelength
perturbations introduce additional difficulties because the inhomogeneous
nature of the medium determines disturbances leading to continuous intervals of
eigenfrequencies which cannot be considered as purely sinusoidal.We analyze the
modification of periods, modes structure and stability when the helicity, the
magnetic field strength and the radius of the fluxtube are varied. The
efficiency of the damping due to the resonant absorption mechanism is analyzed
in a context of modes that can either impulsively release or storage magnetic
energy.We find that the onset of the instability is associated to a critical
value of the helicity and that the magnetic energy content has a determinant
role on the instability of the system with respect to the stabilizing effect of
the resonant absorption mechanism.

Just as Ted Kramer (Dustin Hoffman) is about to get a break in his professional life his frustrated wife Joanna (Meryl Streep) finally gets up the courage to leave him, leaving Ted to care for their five year old son (Justin Henry). Being a single parent proves to be quite the chore for Ted, and he suffers professionally but also learns there's much more to life than a career as he continues to bond with, and really get to know, his own son. But then Joanna returns and intends to get her son back, which leads to a cruel custody trial.<br /><br />Kramer vs. Kramer is a superbly well written and magnificently acted human drama that will only leave the most cold-hearted a viewer untouched. Hoffman's growing relationship with his son is so well portrayed and the film never takes an easy way out. It always feels very real and thanks to the film's low-key approach it makes even more of an impact and can easily work upon multiple viewings, the film's dramatic impact does not lessen.<br /><br />Easily recommended; 10 out of 10.

In this work we study global well-posedness and large time behaviour for a
typical reaction--diffusion system, which include degenerate diffusion, and
whose non-linearities arise from chemical reactions. We show that there is an
{\it indirect diffusion effect}, i.e. an effective diffusion for the
non-diffusive species which is incurred by a combination of diffusion from
diffusive species and reversible reactions between the species. Deriving new
estimates for such degenerate reaction-diffusion system, we show, by applying
the entropy method, that the solution converges exponentially to equilibrium,
and provide explicit convergence rates and associated constants.

Interest in larger-context neural machine translation, including
document-level and multi-modal translation, has been growing. Multiple works
have proposed new network architectures or evaluation schemes, but potentially
helpful context is still sometimes ignored by larger-context translation
models. In this paper, we propose a novel learning algorithm that explicitly
encourages a neural translation model to take into account additional context
using a multilevel pair-wise ranking loss. We evaluate the proposed learning
algorithm with a transformer-based larger-context translation system on
document-level translation. By comparing performance using actual and random
contexts, we show that a model trained with the proposed algorithm is more
sensitive to the additional context.

We consider a branching particle model in which particles move inside a
Euclidean domain according to the following rules. The particles move as
independent Brownian motions until one of them hits the boundary. This particle
is killed but another randomly chosen particle branches into two particles, to
keep the population size constant. We prove that the particle population does
not approach the boundary simultaneously in a finite time in some Lipschitz
domains. This is used to prove a limit theorem for the empirical distribution
of the particle family.

BackgroundDespite recommendations regarding prompt treatment of cases and enhanced hygiene measures, scarlet fever outbreaks increased in England between 2014-2018. We aimed to assess the impact of standard interventions on transmission of Streptococcus pyogenes to classroom contacts, households, and classroom environments.
MethodsWe undertook a prospective, contact tracing study in schools with 2 consecutive scarlet fever cases that were reported to local Health Protection teams in London between March 1st and May 31st in 2018 and 2019. We cultured throat swabs from cases, household contacts, and classroom contacts at four time points. We also cultured hand swabs and cough plates from all cases, and from classroom contacts in 2019. Surface swabs from toys and other fomites in classrooms were cultured in 2018, and settle plates from classrooms were collected in 2019. Any sample with S. pyogenes detected was recorded as positive and underwent emm genotyping and genome sequencing to compare with the outbreak strain.
FindingsSix classes, comprising 12 scarlet fever cases, 17 household contacts, and 278 classroom contacts were recruited from March 1st to May 31st in 2018 and the same period in 2019. Prevalence of the outbreak S. pyogenes strain in throat swabs from asymptomatic classroom contacts was high, increasing from 9.6% (11/115) in week 1, to 26.9% (34/126) in week 2, to 24.1% (26/108) in week 3, then 14.3% (5/35) in week 4. Colonisation with non-outbreak and non-genotyped S. pyogenes strains was 1.7% (2/115); 3.9% (5/126); 5.6% (6/108); and 0/35 in the same weeks. Genome sequencing showed clonality of isolates within each of six classes, confirming recent transmission accounted for high carriage. When transmissibility was tested, children who were asymptomatic carriers of emm4 and emm3.93 had positive cough plates on 1/14 (7.1%) and 7/21 (33.3%) occasions respectively. Only 1/60 surface swabs taken in 3 classrooms yielded the outbreak S. pyogenes strain. In contrast, 2/12 and 6/12 settle plates placed in elevated locations yielded the outbreak S. pyogenes strain in the two classrooms tested.
InterpretationS. pyogenes transmission in schools is intense and may occur prior to, or inspite of reported treatment of cases, underlining a need for rapid case management. Despite guideline adherence, heavy shedding of S. pyogenes by small numbers of classroom contacts may perpetuate outbreaks, and airborne transmission has a plausible role in spread. The findings highlight the need for research to improve understanding and assess effectiveness of interventions to reduce S. pyogenes airborne transmission.

We construct the spin foam model for N=2 supergravity in three dimensions.
Classically, it is a BF theory with gauge algebra osp(2|2). This algebra has
representations which are not completely reducible. This complicates the
procedure when building a state sum. Fortunately, one can and should excise
these representations. We show that the restricted subset of representations
form a subcategory closed under tensor product. The resulting state-sum is once
again a topological invariant. Furthermore, within this framework one can
identify positively and negatively charged fermions propagating on the spin
foam. These results on osp(2|2) representations and intertwiners apply more
generally to spin network states for N=2 loop quantum supergravity (in 3+1
dimensions) where it allows to define a notion of BPS states.

As the left and the media ramp up their Manafort-ian mania against Trump, it appears the trail of destruction from special counsel Mueller's probe has spread to Democratic power-lobbyist Tony Podesta.
As we explained in Aug 2016, Paul Manafort - now under indictment on 12 charges - and his deputy Rick gates previously worked with the Podesta Group, run by Tony Podesta, the brother of Hillary Clinton campaign chairman John Podesta."
Told ya so.

We extend a model of positive feedback and contagion in large mean-field
systems, by introducing a common source of noise driven by Brownian motion.
Although the driving dynamics are continuous, the positive feedback effect can
lead to `blow-up' phenomena whereby solutions develop jump-discontinuities. Our
main results are twofold and concern the conditional McKean--Vlasov formulation
of the model. First and foremost, we show that there are global solutions to
this McKean--Vlasov problem, which can be realised as limit points of a
motivating particle system with common noise. Furthermore, we derive results on
the occurrence of blow-ups, thereby showing how these events can be triggered
or prevented by the pathwise realisations of the common noise.

This paper introduces NSGA-Net -- an evolutionary approach for neural
architecture search (NAS). NSGA-Net is designed with three goals in mind: (1) a
procedure considering multiple and conflicting objectives, (2) an efficient
procedure balancing exploration and exploitation of the space of potential
neural network architectures, and (3) a procedure finding a diverse set of
trade-off network architectures achieved in a single run. NSGA-Net is a
population-based search algorithm that explores a space of potential neural
network architectures in three steps, namely, a population initialization step
that is based on prior-knowledge from hand-crafted architectures, an
exploration step comprising crossover and mutation of architectures, and
finally an exploitation step that utilizes the hidden useful knowledge stored
in the entire history of evaluated neural architectures in the form of a
Bayesian Network. Experimental results suggest that combining the dual
objectives of minimizing an error metric and computational complexity, as
measured by FLOPs, allows NSGA-Net to find competitive neural architectures.
Moreover, NSGA-Net achieves error rate on the CIFAR-10 dataset on par with
other state-of-the-art NAS methods while using orders of magnitude less
computational resources. These results are encouraging and shows the promise to
further use of EC methods in various deep-learning paradigms.

We present a new Milky Way microlensing simulation code, dubbed PopSyCLE
(Population Synthesis for Compact object Lensing Events). PopSyCLE is the first
resolved microlensing simulation to include a compact object distribution
derived from numerical supernovae explosion models and both astrometric and
photometric microlensing effects. We demonstrate the capabilities of PopSyCLE
by investigating the optimal way to find black holes (BHs) with microlensing.
Candidate BHs have typically been selected from wide-field photometric
microlensing surveys, such as OGLE, by selecting events with long Einstein
crossing times ($t_E>120$ days). These events can be selected at closest
approach and monitored astrometrically in order to constrain the mass of each
lens; PopSyCLE predicts a BH detection rate of ~40% for such a program. We find
that the detection rate can be enhanced to ~85% by selecting events with both
$t_E>120$ days and a microlensing parallax of $\pi_E<0.08$. Unfortunately, such
a selection criterion cannot be applied during the event as $\pi_E$ requires
both pre- and post-peak photometry. However, historical microlensing events
from photometric surveys can be revisited using this new selection criteria in
order to statistically constrain the abundance of BHs in the Milky Way. The
future WFIRST microlensing survey provides both precise photometry and
astrometry and will yield individual masses of $\mathcal{O}(100-1000) black
holes, which is at least an order of magnitude more than is possible with
individual candidate follow-up with current facilities. The resulting sample of
BH masses from WFIRST will begin to constrain the shape of the black hole
present-day mass function, BH multiplicity, and BH kick velocity distributions.

Sloppy design. Must remove/replace keyboard every use.
What I didn't see or pick up from any other reviews is that each time you open the case and want to use the iPad, you need to remove the keyboard and reposition it lower so that the ipad can be tilted in viewing position. Then when you are finished, you must again remove and reposition the keyboard so that you can close the case. The keyboard is held in only with a magnet and there are no guides to key the keyboard aligned with the case, so moving and repositioning it becomes very awkward. The magnet is strong, however the keyboard still fell out once. The keyboard is plastic in a plastic casing. A features list included in the packaging says the keyboard is aluminum. Not sure if there aren't any aluminum parts inside the keyboard, but all visible parts are plastic. I REALLY wanted to like this case, but it is simply too awkward to open, use, and close.

Supernova remnants (SNRs) are among the strongest candidates to explain the
flux of cosmic rays below the knee around 10^15 eV. Pulsar wind nebulae (PWNe),
synchrotron nebulae powered by the spin-down of energetic young pulsars,
comprise one of the most populous VHE gamma-ray source classes. Gamma-ray
studies in the GeV and TeV bands probe the nature (ions vs. electrons),
production, and diffusion of high-energy particles in SNRs and PWNe. For
sources that are visible across both the GeV and TeV bands, such as IC 443, the
spatial and spectral distribution of gamma rays can be studied over an
unprecedented energy range. This presentation will review recent VERITAS
results, including studies of Cassiopeia A, IC 443, PSR J1930+1852, and the SNR
G106.3+2.7/Boomerang region, and discuss prospects for complementary studies of
SNRs and PWNe in the Fermi and VHE gamma-ray bands.

It has been demonstrated that the switching of perpendicular magnetization
can be achieved with spin orbit torque (SOT) at an ultrafast speed and low
energy consumption. However, to make the switching deterministic, an
undesirable magnetic field or unconventional device geometry is required to
break the structure inverse symmetry. Here we propose a novel scheme for
SOT-induced field-free deterministic switching of perpendicular magnetization.
The proposed scheme can be implemented in a simple magnetic tunnel junction
(MTJ) /heavy-metal system, without the need of complicated device structure.
The perpendicular-anisotropy MTJ is patterned into elliptical shape and
misaligned with the axis of the heavy metal, so that the uniaxial shape
anisotropy aids the magnetization switching. Furthermore, unlike the
conventional switching scheme where the switched final magnetization state is
dependent on the direction of the applied current, in our scheme the bipolar
switching is implemented by choosing different current paths, which offers a
new freedom for developing novel spintronics memories or logic devices. Through
the macrospin simulation, we show that a wide operation window of the applied
current pulse can be obtained in the proposed scheme. The precise control of
pulse amplitude or pulse duration is not required. The influences of key
parameters such as damping constant and field-like torque strength are
discussed as well.

Only in Canada would people complain that things are going well. What if housing was crashing? Canada is a safe place for investment, with Toronto specifically getting 120,000 new residents each year. Until they build more houses (which will not happen), prices will go up.
People were always calling that Vancouver housing would go down, every year since 1986. Well, they finally got it right in 2017. Congrats that your prediction only took 31 years.

The current accessibility to large medical datasets for training
convolutional neural networks is tremendously high. The associated dataset
labels are always considered to be the real "ground truth". However, the
labeling procedures often seem to be inaccurate and many wrong labels are
integrated. This may have fatal consequences on the performance of both
training and evaluation. In this paper, we show the impact of label noise in
the training set on a specific medical problem based on chest X-ray images.
With a simple one-class problem, the classification of tuberculosis, we measure
the performance on a clean evaluation set when training with label-corrupt
data. We develop a method to compete with incorrectly labeled data during
training by randomly attacking labels on individual epochs. The network tends
to be robust when flipping correct labels for a single epoch and initiates a
good step to the optimal minimum on the error surface when flipping noisy
labels. On a baseline with an AUC (Area under Curve) score of 0.924, the
performance drops to 0.809 when 30% of our training data is misclassified. With
our approach the baseline performance could almost be maintained, the
performance raised to 0.918.

This tired old queue jumping red herring. Basic rule refugees are not immigrants.
There are different queues (and selection criteria) for temporary and permanent immigrants and for refugee claimants. Note the name of our legislation... the Immigration AND Refugee Protection Act .
And there are even different queues for different types of refugee claimants as set out in our international agreements that we have passed into our domestic law in the IRPA.
Refugees who flee their country may apply overseas - usually from refugee camps where they are pre-selected by the UNHCR and then evaluated by Canadian officers abroad or privately sponsored. Refugee claimants may also appear at a Port of Entry and seek protection but if coming from the USA will be sent back per the Safe Third Country Agreement. Refugee claimants may also make claims to an inland immigration officer whether legally or illegally in Canada per the IRPA and are entitled to have the claim processed.
Not queue jumping.

The influence of nonmagnetic central node defect on dynamical properties of
regular square-shaped 5 x 5 segment of magnetic dot array under the thermal
activation is investigated via computer simulations. Using stochastic
Landau-Lifshitz-Gilbert equation we simulate hysteresis and relaxation
processes. The remarkable quantitative and qualitative differences between
magnetic dot arrays with nonmagnetic central node defect and magnetic dot
arrays without defects have been found.

Crumbling mess
To be very honest, I have not so far been impressed. I’ve been using for a week with no change from any other antiperspirant. Also, within a few days, the whole stick crumbled. I was picking up pieces to try to salvage since I paid so much for this. The rest got vacuumed. I would not purchase again.

We investigate models in minimal supergravity parameter space which contain
metastable sleptons. We find the luminosity required to determine the slepton
spin in these scenarios, and apply our analysis to two benchmark models. We
show that the spin of the slepton in one of the benchmark models can be
determined with less than 30 fb$^{-1}$ of data, while the slepton spin in the
other model can be determined with roughly 40 fb$^{-1}$ of data. We show how
our analysis can be applied to other models, and give an estimate of the
luminosity needed for a spin determination as a function of slepton mass. This
analysis can be used to distinguish supersymmetry and extra dimensions.

Let $ X: M \hook S^5$ be a compact Legendrian surface in pseudoconformal(CR)
5-sphere. We introduce a pseudoconformally invariant Willmore type second order
functional $ \W(X)$, and study its critical points called Willmore Legendrian
surfaces. The fifth order structure equations show that Willmore dual can be
defined for a class of Willmore Legendrian surfaces. Moreover when this dual is
constant, Willmore Legendrian surface admits a Weierstra\ss type representation
in terms of immersed meromorphic curve in $ \C^2$ satisfying an appropriate
real period condition via pseudoconformal stereographic projection. We show
that every compact Riemann surface admits a generally one to one, conformal,
Willmore Legendrian immersion in $ S^5$ with constant Willmore dual. As a
corollary, every compact Riemann surface can be conformally immersed in $ \C^2$
as an exact, algebraic Lagrangian surface.

'The government says this is an "unintended" tax advantage that is primarily used by higher-income individuals who have savings that go beyond the annual contribution limits to Registered Retirement Savings Plans and Tax-Free Savings Accounts.'
Yet Trudeau has slashed the TFSA limit as well. And for a small business owner to pay himself a salary (vs. dividends or retained earnings) he/she will soon need to pony up 12% payroll tax as CPP is 'enhanced'.
The only 'unintended' aspect of this reform is opportunity cost of government revenue, in the form of reduced hours, early retirements, relocations, and even foregone small business formation.

Great "documentary" of how scientist's believed dinosaurs behaved, captured with some of the most spectacular CGI since "Jurassic Park". Done completely seriously, like a prehistoric episode of "Nation Geographic". Grabs your attention from the first frame and never lets go. My favorite part was when the Diplodocus fights off the Allosauros.<br /><br />10 stars. This is what science is all about.

We present detailed morphological properties of Lyman alpha emitters (LAEs)
at z~ 5.7 in the COSMOS field, based on {\it Hubble Space Telescope} Advanced
Camera for Surveys (ACS) data. The ACS imaging in the F814W filter covered 85
LAEs of the 119 LAEs identified in the full two square degree field, and 47
LAEs of them are detected in the ACS images. Nearly half of them are spatially
extended with a size larger than 0.15 arcsec (~0.88 kpc at z=5.7) up to 0.4
arcsec (~2.5 kpc at z=5.7). The others are nearly unresolved compact objects.
Two LAEs show double-component structures, indicating interaction or merging of
building components to form more massive galaxies. By stacking the ACS images
of all the detected sources, we obtain a Sersic parameter of n~0.7 with a
half-light radius of 0.13 arcsec (0.76 kpc), suggesting that the majority of
ACS detected LAEs have not spheroidal-like but disk-like or irregular light
profiles. Comparing ACS F814W magnitudes (I_814) with Subaru/Suprime-Cam
magnitudes in the NB816, i', and z' bands, we find that the ACS imaging in the
F814W band mainly probes UV continuum rather than Lyman alpha line emission. UV
continuum sizes tend to be larger for LAEs with larger Ly\alpha emission
regions as traced by the NB816 imaging. The non-detection of 38 LAEs in the ACS
images is likely due to the fact that their surface brightness is even too low
both in the UV continuum and Lyalpha emission. Estimating I_814 for the LAEs
with ACS non-detection from the z' and NB816 magnitudes, we find that 16 of
these are probably LAEs with a size larger than 0.15 arcsec in UV continuum.
All these results suggest that our LAE sample contains systematically larger
LAEs in UV continuum size than those previously studied at z~6.

This is a review of applications of the Color Glass Condensate to the
phenomenology of relativistic heavy ion collisions. The initial stages of the
collision can be understood in terms of the nonperturbatively strong nonlinear
glasma color fields. We discuss how the CGC framework can and has been used to
compute properties of the initial conditions of AA collisions. In particular
this has led to recent progress in understanding multiparticle correlations,
which can provide a directly observable signal of the properties of the initial
stage of the collision process.

There just isn't enough here. There a few funny spots, but not really enough. I was very disappointed because I love stupid movies. I was expecting this to be a hidden gem. IT WAS NOT. It was a hidden turd.<br /><br />The whole time I was watching it I was thinking, "Geez, I could do better than that and I'm a moron". Don't believe the few good reviews. I was suckered in by them. At no point did I laugh at loud. Maybe this was funny or cutting edge in 1987 but man, it fell flat today. This movie had promise, it just didn't deliver on it. Maybe if they rewrote it a few more times. I cant fault the actors. They weren't the best, but they just didn't have much with which to work. This movie failed because of threadbare writing. SORELY disappointed.

It is shown that the strong Atiyah conjecture and the L\"uck approximation
conjecture in the space of marked groups hold for locally indicable groups. In
particular, this implies that one-relator groups satisfy both conjectures. We
also show that the center conjecture, the independence conjecture and the
strong eigenvalue conjecture hold for these groups.
As a byproduct we prove that the group algebra of a locally indicable group
over a field of characteristic zero has a Hughes-free epic division algebra
and, in particular, it is embedded in a division algebra.

I just accidentally stumbled over this film on TV one day. It was aired in the middle of the day on a channel not exactly famous for airing good movies. This one, however, was nothing less then good.<br /><br />October Sky tells the true story of Homer Hickam, a boy inspired by the Sputnick launch to become a rocket scientist. He and his friends begin to build rockets. His father is not to happy about his sons new found hobby and would rather see him become a coal-miner as himself or go to college on a football-scholarship like his brother.<br /><br />The story is well written. A bit too predictable maybe, but that's OK cause it doesn't focus too much on those parts of the story. It's important part, but where this is obvious the inner action, the action between the characters is focused on. The story is good. It has some clichés, but that's OK. It's based on actual event's so you kind of can't just drop out these clichés. The characters are really good. Where the story is on a downhill the characters are brought out and manage to keep the action and the quality of the movie high. You get to know these characters and you get sympathy for them. They are well written and believable.<br /><br />This is a good looking movie. The sets and the 50's style is thorough and the pictures are well composed and well lit. This all sets the mood of the film very good.<br /><br />The acting is really good. Jake Gyllenhaal delivers a great performance as Homer Hickam and Chris Cooper is good as John Hickam. As for the rest of the cast they are good too. All together this makes out a pretty strong cast.<br /><br />All in all I'm glad I caught this movie. It was first after seeing it I learned that it was based on actual events. If I had known that when seeing it, it would probably just be even more interesting. October Sky is a good and interesting movie. It's a movie I believe everyone can enjoy. It's kind of a feel-good movie. Not bad at all!

These posts are so unsupportive of our PM. We are dealing with a reckless, thoughtless, greedy and intrinsically mean American president. Our country is dependent on the decisions coming out of this meeting and future ones. For god's sake, at least pretend to be supportive. Most of you sound like your rooting for Trudeau's failure. It's discouraging and does not reflect well on you.

We study UV properties of the two-dimensional supersymmetric CP^{N-1} model
on non(anti)commutative superspace. We show that the deformed model has the
same UV property as the ordinary model in the leading order of 1/N and the
deformation give rise to UV divergence which cannot be dealt with in the
next-to-leading order.

The speed of an intensity pattern of polarization currents on a circle,
induced within a star by its rotating, magnetized core, will exceed the speed
of light for a sufficiently large star, and/or rapid rotation, and will, in
turn, generate focused electromagnetic beams which disrupt them. Upon core
collapse within such a star, the emergence of these beams will concentrate near
the two rotational poles, driving jets of matter into material previously
ejected via the same excitation mechanism acting through the pre-core-collapse
rotation of its magnetized stellar core(s). This interpenetration of material,
light-days in extent from the progenitor, produces a significant fraction of
the total supernova luminosity, and the magnitude and time of maximum of this
contribution both vary with the progenitor's rotational orientation. The net
effect is to render supernovae unusable as standard candles without further
detailed understanding, leaving no firm basis, at this time, to favor any
cosmology, including those involving "Dark Energy." Thus we are not now, nor
have we ever been, in an era of precision cosmology, nor are we likely to be
anytime soon. Mass loss induced through the same mechanism also keeps
aggregates of gas and plasma in the early Universe, or at any other epoch, from
forming the ~billion solar mass stars which have been suggested to produce
~billion solar mass black holes via "direct collapse," but can also provide a
signature to predict core collapse some months in advance.

Many people will try to sway the opinions of others by telling a story in a way that minimizes one's own responsibility. The author (not a reporter as this is dripping with bias), wants the reader to believe that she could not be both telling the truth AND spinning her role to minimize it. That doesn't mean that what she has said about the events that took place is false. To the author - it you don't believe it go do real journalism and prove that her representation is somehow false. Nothing said by Brazile is either hard to believe or out of character for the people involved. So what exactly is false about the Donna Brazile story?

The Large Synoptic Survey Telescope (LSST) will be a large, wide-field
ground-based system designed to obtain, starting in 2015, multiple images of
the sky that is visible from Cerro Pachon in Northern Chile. About 90% of the
observing time will be devoted to a deep-wide-fast survey mode which will
observe a 20,000 deg$^2$ region about 1000 times during the anticipated 10
years of operations (distributed over six bands, $ugrizy$). Each 30-second long
visit will deliver 5$\sigma$ depth for point sources of $r\sim24.5$ on average.
The co-added map will be about 3 magnitudes deeper, and will include 10 billion
galaxies and a similar number of stars. We discuss various measurements that
will be automatically performed for these 20 billion sources, and how they can
be used for classification and determination of source physical and other
properties. We provide a few classification examples based on SDSS data, such
as color classification of stars, color-spatial proximity search for wide-angle
binary stars, orbital-color classification of asteroid families, and the
recognition of main Galaxy components based on the distribution of stars in the
position-metallicity-kinematics space. Guided by these examples, we anticipate
that two grand classification challenges for LSST will be 1) rapid and robust
classification of sources detected in difference images, and 2) {\it
simultaneous} treatment of diverse astrometric and photometric time series
measurements for an unprecedentedly large number of objects.
