This movie is supposed to take place in Milford NJ. I know the house that it is based on as well as the person. As you see at the end of themovie, she was killed in the world trade center incident. I know that, because I was one of the police officers that helped with the identification of her remains. (She was the only one in our area lost). The nudity in the movie went a bit far. I am not a prude but the actors could have filmed the scene with the two woman without actually showing the whole thing. This movie is in poor taste and I cannot see how her family would give there blessing to it. This is an insult to the person whom it is based on.

We study the minimal SUGRA phenomenology in the case of an alternative seesaw
mechanism for generating neutrino masses. Changes in the neutrino sector lead
to a modification of the supersymmetric particle spectrum and the sneutrino
naturally arises as the lightest supersymmetric particle. The obtained
sneutrino has a relic density within the WMAP range and is compatible with
present nuclear recoil bounds.

Works fine, but not the fanciest laptop bag
The main reason I marked a 3 is because the front pocket is a fake pocket. I was planning on putting my phone in the pocket as a quick on-the-go spot, but it is only half an inch deep (about enough room to put a pen in it LOL). The leather straps are a bit cheap but have not broken yet since I bought this two months ago (although I fear they will start to fray). The inside organization (two sections and one zippered pocket and one open pocket) is great. I use the removable zippered pouch for my battery.

Recently the two-loop next-to-leading logarithmic (NLL) virtual corrections
to arbitrary processes with massless external fermions have been calculated.
Within the spontaneously broken electroweak theory the one- and two-loop mass
singularities have been derived to NLL accuracy and expressed as universal
correction factors depending only on the quantum numbers of the external
particles. This talk summarizes the results for massless fermionic processes
and presents new aspects arising in the extension of the corresponding loop
calculations to massive external fermions. As a preliminary result, the Abelian
form factor for massive fermions is given.

In many fields of science, high-dimensional integration is required.
Numerical methods have been developed to evaluate these complex integrals. We
introduce the code i-flow, a python package that performs high-dimensional
numerical integration utilizing normalizing flows. Normalizing flows are
machine-learned, bijective mappings between two distributions. i-flow can also
be used to sample random points according to complicated distributions in high
dimensions. We compare i-flow to other algorithms for high-dimensional
numerical integration and show that i-flow outperforms them for high
dimensional correlated integrals. The i-flow code is publicly available on
gitlab at https://gitlab.com/i-flow/i-flow.

I disliked this film intensely and left during the scene where the loyalist gang are shot up by the British. The film effectively blames the people of NI as being the cause of their own troubles. It suggests that the 25 year war was a question of intransigence and nothing to do with Britain's partition of Ireland and domination of its history i.e. NI was created by Britain in 1921 irrespective of the wishes of the rest of Ireland.<br /><br />The characters are portrayed as hapless fools, even though I despise loyalist paramilitaries they were fighting for a cause - maintaining their artificial privileges over the Catholic community. It is a known fact that British Intelligence collaborated with loyalists during the war, no doubt to keep the Catholics at bay and demoralise republicanism.<br /><br />Nineties' values about 'machismo', masculinity etc are transposed on to 1970s Belfast and are portrayed as part of the supposedly unique Irish 'psyche' which leads to violence. The stupid song from the woman in the club - old Ireland of green fields ..blah..blah.. - is given a symbolic stature, i.e. poor young fools fighting for an impossible cause. Tedious, ahistorical, cheap and nasty trash. O'Sullivan has made a personal statement on a conflict which requires serious political analysis.

My experience: good headphones. 2 pack is worth the low price.
Great value since you get two pairs. Seams where cord meets jack and ear piece are good, not the kind that short out when bent lightly. I like the flat cord, metal ear pieces, and volume controls in middle. Volume control slider is medium resistant so no unintended changes. I will be purchasing these again soon!

We discuss the physical interpretation of a dynamical and inhomogeneous
spherically symmetric solution obtained by Fonarev for a scalar field with an
exponential potential. There is a single parameter $w$ in the solution which
can be set to $\pm1$ if it is non-zero, in addition to the steepness parameter
$\lambda$ in the potential. The spacetime is conformally static and
asymptotically flat Friedmann-Robertson-Walker spacetime. The solution reduces
to the Friedmann-Robertson-Walker solution for $w=0$. There are two curvature
singularities, of which one is a timelike central singularity and the other is
a big-bang or big-crunch type singularity. Depending on the parameters, the
spacetime can possess a future outer trapping horizon in the collapsing case.
Then the solution represents a dynamical black hole in the sense of Hayward
although there is a locally naked singularity at the center and no black-hole
event horizon. This demonstrates a weak point of the local definition of a
black hole in terms of a trapping horizon.

In the local Universe, globular clusters (GCs) with metallicities $[{\rm
Fe}/{\rm H}]<-2.5$ are extremely rare. In this Letter, the close connection
between GC formation and galaxy evolution is used to show that this GC
metallicity `floor' results from the galaxy mass-metallicity relation of ultra
low-luminosity galaxies (ULLGs) at high redshift, where the most metal-poor GCs
must have formed. Galaxies with metallicities $[{\rm Fe}/{\rm H}]\lesssim-2.5$
have too low masses to form GCs with initial masses $M_{\rm i}\gtrsim10^5~{\rm
M}_\odot$, needed to survive for a Hubble time. This translates the galaxy
mass-metallicity relation into a maximum initial cluster mass-metallicity
relation for $[{\rm Fe}/{\rm H}]\lesssim-1.8$, which naturally leads to the
observed colour-magnitude relation of metal-poor GCs at $z=0$ (the `blue
tilt'). Its strength traces the slope of the gas phase mass-metallicity
relation of ULLGs. Based on the observed blue tilt of GCs in the Virgo and
Fornax Clusters, the galaxy mass-metallicity relation is predicted to have a
slope of $\alpha=0.4\pm0.1$ for $10^5\lesssim M_\star/{\rm
M}_\odot\lesssim10^7$ at $z\gtrsim2$. The GC metallicity floor implies a
minimum host galaxy mass and a maximum redshift for GC formation. Any proto-GCs
that may be detected at $z>9$ are most likely to end up in galaxies presently
more massive than the Milky Way, whereas GCs in low-mass galaxies such as the
Fornax dSph ($M_\star\approx4\times10^7~{\rm M}_\odot$) formed at $z\lesssim3$.

Internet of Things is revolutionizing the current era with its vast usage in
number of fields such as medicine, automation, home security, smart cities,
etc. As these IoT devices' uses are increasing, the threat to its security and
to its application protocols are also increasing. Traffic passing over these
protocol if intercepted, could reveal sensitive information and result in
taking control of the entire IoT network. Scope of this paper is limited to
MQTT protocol. MQTT (MQ Telemetry Transport) is a light weight protocol used
for communication between IoT devices. There are multiple brokers as well as
clients available for publishing and subscribing to services. For security
purpose, it is essential to secure the traffic, broker and end client
application. This paper demonstrates extraction of sensitive data from the
devices which are running broker and client application.

Great for nut free schools
My son is in a nut free class and is required to bring foods that haven't been processed in a facility with nuts. It's hard to find a lot of options for him as he also has a gluten intolerance. I appreciate that these are safe for allergies, taste good and are individually packaged which makes them easy for school snack time and lunches. They are VERY small though, which is typical for any type of allergy friendly food, but it is still a deterrent for me.

Terrible!!! I don't want to be too negative but this film has an IQ of stupid monkey.What a disaster.I just couldn't believe how bad this movie is.The dialogs are just very strange and off topic,the camera work at times just horrible,the music at times like a soundtrack for Lawrence of Arabia,I just watched this film to see how much worse it can get.Some of the side kick "actors" are total disaster.Sorry but all my thumbs and toes and anything that can hang downwards on my body is falling to the ground. Harvey Keitle is a great actor but who knows maybe he is in financial crunch to take a part in such a fiasco film. . . . . this movie should have been presented to all the students in all the film schools just to teach them a lesson of how not to make a film

I have not seen this movie! At least not in its entirety. I have seen a few haunting clips which have left me gagging to see it all. One sequence remains in my memory to this day. A (very convincing looking) spacecraft is orbiting the dark side of the moon. The pilot releases a flash device in order to photograph the hidden surface below him. The moon flashes into visability . . . . and for a few seconds there it is. Parallel lines, squares, Could it be .. then the light fades and the brief glimse of ...what... has gone and it is time for the spacecraft to return to Earth. Wonderful. I have seen some other clips too but would LOVE to obtain the full movie.

I've heard a few comments, particularly from prisoners of war, that CHANGI is not historically accurate, and that it is disappointing. Perhaps it is for those who actually had to live through this stuff, and much worse. But for the rest of us, who really have no idea of how prisoners were treated by the Japanese during World War II, CHANGI is a remarkable introduction. But CHANGI isn't a war documentary - if it had have been, then the historical accuracy aspect would have been paramount. It is a miniseries drama, with fictional characters and fictional situations (though based loosely on actual events I've heard and read about) - and at the centre of the story is the ideal of mateship. This group of young Australian soldiers, taken prisoner by the Japanese and held in appalling conditions for years, became mates through adversity and the strength of their friendships continued throughout their lives after the war. It is also a cultural study of the differences between the Japanese of the time and the western world, with its music, games and entertainment: in part 5, when it is becoming clear that Japan will lose the war after Germany has surrendered in Europe, the Japanese prison camp colonel insists that his country must study the culture of their prisoners - in order to defeat a people, one must defeat their culture - and to do this, one must understand it. All in all, Australia continues its rich tradition of producing exceptional television miniseries, and is an unrivalled world leader in this regard: vyeing for the AFI Award with CHANGI is MY BROTHER JACK, the adaptation of George Johnston's novel, and also a worthy winner. Miniseries in recent years include DAY OF THE ROSES (the story of the investigation into the Glanville train crash), KINGS IN GRASS CASTLES (the adaptation of Mary Durack's historical account of her pioneering ancestors), KANGAROO PALACE (about a group of friends from a country town in Australia who travel to London and change and grow apart), and the (somewhat disappointing) adaptation of Bryce Courtenay's powerful novel, THE POTATO FACTORY. Less recently: Nancy Cato's sweeping saga of life on the Murray - ALL THE RIVERS RUN; Cusack & James' brilliant novel about postwar life in Sydney - COME IN SPINNER; Colleen McCullough's outstanding pioneering saga - THE THORN BIRDS; THE RIVER KINGS; Ruth Park's novel THE HARP IN THE SOUTH; BODYLINE; EUREKA STOCKADE; ANZACS; etc..., etc... (Of course, there have been some not-so-good productions - for instance, MOBY DICK, DO OR DIE, ON THE BEACH, THORN BIRDS: THE MISSING YEARS; etc...) Generally, though, if an Australian miniseries comes your way, make sure you see it - and this goes double for CHANGI, a superbly directed masterpiece. Rating: 9/10.

We study some notions of negative dependence of a sampling scheme that can be
used to derive variance bounds for the corresponding estimator or discrepancy
bounds for the underlying random point set that are at least as good as the
corresponding bounds for plain Monte Carlo sampling.
We provide new pre-asymptotic bounds with explicit constants for the star
discrepancy and the weighted star discrepancy of sampling schemes that satisfy
suitable negative dependence properties. Furthermore, we compare the different
notions of negative dependence and give several examples of negatively
dependent sampling schemes.

M. Levin defined a real number $x$ that satisfies that the sequence of the
fractional parts of $(2^n x)_{n\geq 1}$ are such that the first $N$ terms have
discrepancy $O((\log N)^2/ N)$, which is the smallest discrepancy known for
this kind of parametric sequences. In this work we show that the fractional
parts of the sequence $(2^n x)_{n\geq 1}$ fail to have Poissonian pair
correlations. Moreover, we show that all the real numbers $x$ that are variants
of Levin's number using Pascal triangle matrices are such that the fractional
parts of the sequence $(2^n x)_{n\geq 1}$ fail to have Poissonian pair
correlations.

Disney? What happened? I really wish the movie had been set in the 60's ;like the book was. And I really could have dealt with cheap special effects in order to save the budget for a more accurate adaption..... I'm glad that, maybe, someone might be influenced to read the books..... but, The Man With Red Eyes interchangeable as IT? And what's up with the volcanic upheaval? Where was THAT in the book? Peter Jackson! Save us!!!! A long time ago (1978) I heard that there was European version of this film. I sure wish I could id it. I can only imagine it might be closer to the real story than this poor adaption. This movie needs to be X'd.

Word embeddings carry stereotypical connotations from the text they are
trained on, which can lead to invalid inferences in downstream models that rely
on them. We use this observation to design a mechanism for measuring
stereotypes using the task of natural language inference. We demonstrate a
reduction in invalid inferences via bias mitigation strategies on static word
embeddings (GloVe). Further, we show that for gender bias, these techniques
extend to contextualized embeddings when applied selectively only to the static
components of contextualized embeddings (ELMo, BERT).

The reversible Markov chains that drive the data augmentation (DA) and
sandwich algorithms define self-adjoint operators whose spectra encode the
convergence properties of the algorithms. When the target distribution has
uncountable support, as is nearly always the case in practice, it is generally
quite difficult to get a handle on these spectra. We show that, if the
augmentation space is finite, then (under regularity conditions) the operators
defined by the DA and sandwich chains are compact, and the spectra are finite
subsets of $[0,1)$. Moreover, we prove that the spectrum of the sandwich
operator dominates the spectrum of the DA operator in the sense that the
ordered elements of the former are all less than or equal to the corresponding
elements of the latter. As a concrete example, we study a widely used DA
algorithm for the exploration of posterior densities associated with Bayesian
mixture models [J. Roy. Statist. Soc. Ser. B 56 (1994) 363--375]. In
particular, we compare this mixture DA algorithm with an alternative algorithm
proposed by Fr\"{u}hwirth-Schnatter [J. Amer. Statist. Assoc. 96 (2001)
194--209] that is based on random label switching.

We show that all permutations in $S_n$ can be generated by affine unicritical
polynomials. We use the $\operatorname{PGL}$ group structure to compute the
cycle structure of permutations with low Carlitz rank. The tree structure of
the group generated by shift and inversion maps is used to study the randomness
properties of permutation polynomials.

The Global Network of Optical Magnetometers to search for Exotic physics
(GNOME) is a network of geographically separated, time-synchronized, optically
pumped atomic magnetometers that is being used to search for correlated
transient signals heralding exotic physics. The GNOME is sensitive to nuclear-
and electron-spin couplings to exotic fields from astrophysical sources such as
compact dark-matter objects (for example, axion stars and domain walls).
Properties of the GNOME sensors such as sensitivity, bandwidth, and noise
characteristics are studied in the present work, and features of the network's
operation (e.g., data acquisition, format, storage, and diagnostics) are
described. Characterization of the GNOME is a key prerequisite to searches for
and identification of exotic physics signatures.

Quantizing large Neural Networks (NN) while maintaining the performance is
highly desirable for resource-limited devices due to reduced memory and time
complexity. It is usually formulated as a constrained optimization problem and
optimized via a modified version of gradient descent. In this work, by
interpreting the continuous parameters (unconstrained) as the dual of the
quantized ones, we introduce a Mirror Descent (MD) framework for NN
quantization. Specifically, we provide conditions on the projections (i.e.,
mapping from continuous to quantized ones) which would enable us to derive
valid mirror maps and in turn the respective MD updates. Furthermore, we
present a numerically stable implementation of MD that requires storing an
additional set of auxiliary variables (unconstrained), and show that it is
strikingly analogous to the Straight Through Estimator (STE) based method which
is typically viewed as a "trick" to avoid vanishing gradients issue. Our
experiments on CIFAR-10/100, TinyImageNet, and ImageNet classification datasets
with VGG-16, ResNet-18, and MobileNetV2 architectures show that our MD variants
obtain quantized networks with state-of-the-art performance. Code is available
at https://github.com/kartikgupta-at-anu/md-bnn.

We present a new method for extracting numerically exact imaginary-time Green
functions from standard Hirsch-Fye quantum Monte Carlo (HF-QMC) simulations
within dynamical mean-field theory. By analytic continuation, angular resolved
spectra are obtained without the discretization bias previously associated with
HF-QMC results. The method is shown to be accurate even at very low
temperatures (T=W/800 for bandwidth W) in the strongly correlated regime.

Talk about your classics! Ernie Fossilus (the Foss from here on out) came up with a cute and creative trailer totally spoofing Star Wars. This gem is so jammed packed with tributes and gags I laugh every time! Not only that, when Star Wars did a re-issue with new special effects, Hardware Wars did the same! Talk about a spoof that just won't die! There's a reason George Lucas calls this his favorite parody. He was so impressed, he even hired the Foss to work on "Return of the Jedi" (Don't believe me, check his entry in IMDb!)<br /><br />This has to be the first, and in my opinion, the best parody ever done. I think the Special Edition was a bit overdone, but on reflection, I think it's PERFECT for the modern day re-release of Star Wars, and goes to prove that sometimes, it's wrong to mess with perfection.<br /><br />Yes, it's only 10 minutes, but it's well worth your time.<br /><br />You'll laugh, you'll cry, you'll kiss $3 goodbye! Well, maybe 15 for the DVD, but you'll be real happy you did.

The relativistic five-quark equations are found in the framework of the
dispersion relation technique. The five-quark amplitude for the N(1688)
resonance including u-, d- quarks is calculated. The pole of this amplitude
determines the mass of non-strange pentaquark M=1686 MeV and the width about
7MeV. The results are in good agreement with the evidence for a narrow N(1688)
resonance.

We find that dipolar interactions favor ferromagnetic ordering of elongated
crystals of Mn12 Acetate below 0.8 K. Ordered crystals must possess domain
walls. Motion of the wall corresponds to a moving front of Landau-Zener
transitions between quantum spin levels. Structure and mobility of the wall are
computed. The effect is robust with respect to inhomogeneous broadening and
decoherence.

Standard arguments state that Bose Einstein condensation (BEC) cannot occur
in dimensions lower than three in the thermodynamic limit as the expressions
for the number of bosons in the excited states are unbounded. These arguments
imply that the number density is infinite, which is an extraordinary condition.
As an alternative to this pedagogy, we explore the use of regularization
techniques to show that the number density of bosons in the excited state is
finite in two and one dimensions at low temperatures, making it possible to
have a BEC transition in the thermodynamic limit. We suggest creating a
two-dimensional optical traps of increasing sizes to test this hypothesis as
the thermodynamic limit is approached.

We study the dynamics of an electron weakly coupled to a phonon gas. The
initial state of the electron is the superposition of two spatially localized
distant bumps moving towards each other, and the phonons are in a thermal
state. We investigate the dynamics of the system in the kinetic regime and show
that the time evolution makes the non-diagonal terms of the density matrix of
the electron decay, destroying the interference between the two bumps. We show
that such a damping effect is exponential in time, and the related decay rate
is proportional to the total scattering cross section of the electron-phonon
interaction.

Large transformer-based language models (LMs) trained on huge text corpora
have shown unparalleled generation capabilities. However, controlling
attributes of the generated language (e.g. switching topic or sentiment) is
difficult without modifying the model architecture or fine-tuning on
attribute-specific data and entailing the significant cost of retraining. We
propose a simple alternative: the Plug and Play Language Model (PPLM) for
controllable language generation, which combines a pretrained LM with one or
more simple attribute classifiers that guide text generation without any
further training of the LM. In the canonical scenario we present, the attribute
models are simple classifiers consisting of a user-specified bag of words or a
single learned layer with 100,000 times fewer parameters than the LM. Sampling
entails a forward and backward pass in which gradients from the attribute model
push the LM's hidden activations and thus guide the generation. Model samples
demonstrate control over a range of topics and sentiment styles, and extensive
automated and human annotated evaluations show attribute alignment and fluency.
PPLMs are flexible in that any combination of differentiable attribute models
may be used to steer text generation, which will allow for diverse and creative
applications beyond the examples given in this paper.

Experimental and theoretical studies are made of Brownian particles trapped
in a periodic potential, which is very slightly tilted due to gravity. In the
presence of fluctuations, these will trigger a measurable average drift along
the direction of the tilt. The magnitude of the drift varies with the ratio
between the bias force and the trapping potential. This can be closely compared
to a theoretical model system, based on a Fokker-Planck-equation formalism. We
show that the level of control and measurement precision we have in our system,
which is based on cold atoms trapped in a 3D dissipative optical lattice, makes
the experimental setup suitable as a testbed for fundamental statistical
physics. We simulate the system with a very simplified and general classical
model, as well as with an elaborate semi-classical Monte-Carlo simulation. In
both cases, we achieve good qualitative agreement with experimental data.

The structure of the CMS inner tracking system has been studied using nuclear
interactions of hadrons striking its material. Data from proton-proton
collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are
used to reconstruct millions of secondary vertices from these nuclear
interactions. Precise positions of the beam pipe and the inner tracking system
elements, such as the pixel detector support tube, and barrel pixel detector
inner shield and support rails, are determined using these vertices. These
measurements are important for detector simulations, detector upgrades, and to
identify any changes in the positions of inactive elements.

Western thinking underwent a turning point between 1885 and 1925. Einstein in
1905 symbolizes the emblematic hinge of this change of direction. To find an
equivalent phenomenon in the past we need to go back to the period from the XV
century to the XVII century. It was not a mere reform of codes but a new code.
In 1905 the perception of reality changed through the introduction of
relativism in three levels of the reference systems: the ego-other relation,
the world perceived by the senses, and the 'ideal' universe of the concepts. We
will try to identify how this change was expressed and developed in the cited
levels, both in the physic and nature based sciences, in the social sciences,
and in literature and fine arts. Today, 100 years after, the 1905's generation
still proposes us two options: to live sheltered by the dogma that reassures us
with its only and exclusive viewpoint claimed objective, or to dare to live
with the multiple, the transient, the relative. The first way led to the worst
regimes and intolerant ideas of the XX century, the second option throws us
into the uncertainty of the creative adventure, but also leads us to the
possibility of a fairer society in the XXI century.

Not good quality - order from a different seller
Fits okay - not at all what I expected though. The pom poms are not as pictured, they are just in a layer of tulle and pooling at the bottom. After one wear they are just in a big clump. Not good. I'm not happy but she's worn it so I won't return.

Fast linear transforms are ubiquitous in machine learning, including the
discrete Fourier transform, discrete cosine transform, and other structured
transformations such as convolutions. All of these transforms can be
represented by dense matrix-vector multiplication, yet each has a specialized
and highly efficient (subquadratic) algorithm. We ask to what extent
hand-crafting these algorithms and implementations is necessary, what
structural priors they encode, and how much knowledge is required to
automatically learn a fast algorithm for a provided structured transform.
Motivated by a characterization of fast matrix-vector multiplication as
products of sparse matrices, we introduce a parameterization of
divide-and-conquer methods that is capable of representing a large class of
transforms. This generic formulation can automatically learn an efficient
algorithm for many important transforms; for example, it recovers the $O(N \log
N)$ Cooley-Tukey FFT algorithm to machine precision, for dimensions $N$ up to
$1024$. Furthermore, our method can be incorporated as a lightweight
replacement of generic matrices in machine learning pipelines to learn
efficient and compressible transformations. On a standard task of compressing a
single hidden-layer network, our method exceeds the classification accuracy of
unconstrained matrices on CIFAR-10 by 3.9 points -- the first time a structured
approach has done so -- with 4X faster inference speed and 40X fewer
parameters.

For $25 it’s worth it.
For $25 it’s worth the money. Up to 100 yards it does just about as well as could be expected. The eye piece is unnecessarily small in my opinion, and forces you to basically press your eye against the front lens. The bipod is absolutely garbage.

The dualistic structure of statistical manifolds in information geometry
yields eight types of geodesic triangles passing through three given points,
the triangle vertices. The interior angles of geodesic triangles can sum up to
$\pi$ like in Euclidean/Mahalanobis flat geometry, or exhibit otherwise angle
excesses or angle defects. In this paper, we initiate the study of geodesic
triangles in dually flat spaces, termed Bregman manifolds, where a generalized
Pythagorean theorem holds. We consider non-self dual Bregman manifolds since
Mahalanobis self-dual manifolds amount to Euclidean geometry. First, we show
how to construct geodesic triangles with either one, two, or three interior
right angles, whenever it is possible. Second, we report a construction of
triples of points for which the dual Pythagorean theorems hold simultaneously
at a point, yielding two dual pairs of dual-type geodesics with right angles at
that point.

Most approaches to extraction multiple relations from a paragraph require
multiple passes over the paragraph. In practice, multiple passes are
computationally expensive and this makes difficult to scale to longer
paragraphs and larger text corpora. In this work, we focus on the task of
multiple relation extraction by encoding the paragraph only once (one-pass). We
build our solution on the pre-trained self-attentive (Transformer) models,
where we first add a structured prediction layer to handle extraction between
multiple entity pairs, then enhance the paragraph embedding to capture multiple
relational information associated with each entity with an entity-aware
attention technique. We show that our approach is not only scalable but can
also perform state-of-the-art on the standard benchmark ACE 2005.

The problem of fair division of indivisible goods is a fundamental problem of
social choice. Recently, the problem was extended to the case when goods form a
graph and the goal is to allocate goods to agents so that each agent's bundle
forms a connected subgraph. For the maximin share fairness criterion
researchers proved that if goods form a tree, allocations offering each agent a
bundle of at least her maximin share value always exist. Moreover, they can be
found in polynomial time. We consider here the problem of maximin share
allocations of goods on a cycle. Despite the simplicity of the graph, the
problem turns out to be significantly harder than its tree version. We present
cases when maximin share allocations of goods on cycles exist and provide
results on allocations guaranteeing each agent a certain portion of her maximin
share. We also study algorithms for computing maximin share allocations of
goods on cycles.

Business leaders in Japan on Wednesday underlined their determination to further boost digital innovation this year as part of efforts for the country to lead the global economy.
In a New Year message, Hiroaki Nakanishi, chairman of the Japan Business Federation, said the country's most influential business lobby known as Keidanren hopes to further develop digital technologies to make people's lives happier and solve social problems.
He said the business lobby will be committed to rule-making for digital transformation and economic structural reforms to address the graying and decreasing population in the country.
Nakanishi also said Keidanren welcomes the entry into force Wednesday of a Japan-U.S. trade deal, which lowers tariffs on farm and industrial goods, agreed on by Prime Minister Shinzo Abe and President Donald Trump in September.
"We will promote private-sector diplomacy to maintain and strengthen free and open international economic order in the hope of contributing to stability and growth of the global economy," Nakanishi said.
Kengo Sakurada, chairman of the Japan Association of Corporate Executives, called on Japan to take initiative in rule-making on use of digital data and taxation of information technology giants.
"Japan needs to compile its own regulations and rules on digital data ahead of overseas countries," Sakurada said. He especially sought deregulation in the fields of online medical services and autonomous driving.
Sakurada also urged Japan to express its determination to reduce greenhouse gas emissions with its cutting-edge technologies.
Akio Mimura, chairman of the Japan Chamber of Commerce and Industry, said it is urgently needed to introduce digital technologies to small and midsize firms across the country to increase their productivity.
To boost the regional economy, Mimura said the chamber aims to make the most of indigenous resources and external demand including inbound travelers to promote local tourism and the tie-up among agricultural, commercial and manufacturing sectors.

We set up a general framework for Calder\'on projectors (and their
generalization to non-compact manifolds), associated with complex Laplacians
e.g. obtained by Wick rotation of a Lorentzian metric. In the analytic case, we
use this to show that the Laplacian's Green's functions have analytic
continuations whose boundary values are two-point functions of analytic
Hadamard states. The result does not require the metric to be stationary. As an
aside, we describe how thermal states are obtained as a special case of this
construction if the coefficients are time-independent.

Unusable - Item came damaged and unable to return
Purchased this item shortly after moving into a new home. Took a few weeks to get to a point where I could install. When I opened the package, I found the item to be damaged. The internal pins are bent. I can lock/unlock the door with a key but the keyless portion - which is the WHOLE POINT OF THIS PRODUCT - is unusable. Shame on me I guess for opening the package outside the Amazon return window as now it appears I have zero recourse to replace. Spent $73 on a pile of junk and I am NOT happy.

Genre: Cartoon short with no dialogue, African girl and lion.<br /><br />Main characters: Inki, the lion and the minah bird. <br /><br />What happens: A lion wants to eat an African girl called Inki. There is also a rather confusing Minah bird. Is he on Inki's, or the lion's side..?<br /><br />Message: Erm
<br /><br />My thoughts: I agree with Lee Eisenberg, this is rather mean on poor African people!! :-( I like how the main character, Inki (who is an African girl) is quite a nice main character, but they still portray her rudely and make a younger audience not like her very much just because she's HUNTING!! GRRR CHARLES M. JONES!! I don't like the lion very much and I think the minah bird is ALL RIGHT (I suppose). Personally I prefer Charles M. Jones's Looney Tunes cartoons in the future.<br /><br />If you want to watch this anyway, then I recommend the website YouTube. Just type in "Inki" on the space in the main page and you're there. <br /><br />I wish Charles M. Jones had been nicer to Inki in this short. So there. <br /><br />Recommended to: People who are interested in old cartoons and/or people who are just messing around on You Tube.

The aim of this paper is to study the global existence of solutions to a
coupled wave-Klein-Gordon system in space dimension two when initial data are
small, smooth and mildly decaying at infinity. Some physical models strictly
related to general relativity have shown the importance of studying such
systems, but very few results are know at present in low space dimension. We
study here a model two-dimensional system, in which the non-linearity writes in
terms of 'null forms', and show the global existence of small solutions. Our
goal is to prove some energy estimates on the solution when a certain number of
Klainerman vector fields is acting on it, and some optimal uniform estimates.
The former ones are obtained using systematically quasi-linear normal forms, in
their para-differential version; the latter ones are recovered by deducing a
new coupled system of a transport equation and an ordinary differential
equation from the starting PDE system, by means of a semi-classical micro-local
analysis of the problem. We expect the strategy developed here to be robust
enough to enable us, in the future, to treat the case of the most general
non-linearities.

We investigate general properties of Kerr-Schild (KS) metrics in n>4
spacetime dimensions. First, we show that the Weyl tensor is of type II or more
special if the null KS vector k is geodetic (or, equivalently, if
T_{ab}k^ak^b=0). We subsequently specialize to vacuum KS solutions, which
naturally split into two families of non-expanding and expanding metrics. After
demonstrating that non-expanding solutions are equivalent to the known class of
vacuum Kundt solutions of type N, we analyze expanding solutions in detail. We
show that they can only be of the type II or D, and we characterize optical
properties of the multiple Weyl aligned null direction (WAND) k. In general, k
has caustics corresponding to curvature singularities. In addition, it is
generically shearing. Nevertheless, we arrive at a possible "weak" n>4
extension of the Goldberg-Sachs theorem, limited to the KS class, which matches
previous conclusions for general type III/N solutions. In passing, properties
of Myers-Perry black holes and black rings related to our results are also
briefly discussed.

This paper provides an introduction to the Text Encoding Initia-tive (TEI),
focused at bringing in newcomers who have to deal with a digital document
project and are looking at the capacity that the TEI environment may have to
fulfil his needs. To this end, we avoid a strictly technical presentation of
the TEI and concentrate on the actual issues that such projects face, with
parallel made on the situation within two institutions. While a quick
walkthrough the TEI technical framework is provided, the papers ends up by
showing the essential role of the community in the actual technical
contributions that are being brought to the TEI.

Don't eat animal protein
Main premises of the book could be condensed into approximately 20 to thirty pages. Animal protein bad , WFPB protein good. The rest of the book drones on and on about how the dairy, pharmaceutical and processed food industries have corrupted the university and medical professionals to chase money not good food and patient care/health.

Poor packaging and presentation
They arrived in packaging with absolutely no bubble wrap or anything to protect the earings. The earings were not attached to the earing holder card but the backs were on them which shows they just threw them in the package seperately. One of the earing backs arrived broken, it looks like it may have been broken before they even sent them. Poor quality and very bad presentation. I attached photos for reference on how they arrived exactly when i pulled everything out of the small packaging. Will definitely not repurchase from this seller again. Very disappointed.

Static analysis is one of the most widely adopted techniques to find software
bugs before code is put in production. Designing and implementing effective and
efficient static analyses is difficult and requires high expertise, which
results in only a few experts able to write such analyses. This paper explores
the opportunities and challenges of an alternative way of creating static bug
detectors: neural bug finding. The basic idea is to formulate bug detection as
a classification problem, and to address this problem with neural networks
trained on examples of buggy and non-buggy code. We systematically study the
effectiveness of this approach based on code examples labeled by a
state-of-the-art, static bug detector. Our results show that neural bug finding
is surprisingly effective for some bug patterns, sometimes reaching a precision
and recall of over 80%, but also that it struggles to understand some program
properties obvious to a traditional analysis. A qualitative analysis of the
results provides insights into why neural bug finders sometimes work and
sometimes do not work. We also identify pitfalls in selecting the code examples
used to train and validate neural bug finders, and propose an algorithm for
selecting effective training data.

We investigate reaction mechanisms occurring in heavy ion collisions at low
energy (around 20 MeV/u). In particular, we focus on the competition between
fusion and break-up processes (Deep-Inelastic and fragmentation) in
semi-peripheral collisions, where the formation of excited systems in various
conditions of shape and angular momentum is observed. Adopting a Langevin
treatment for the dynamical evolution of the system configuration, described in
terms of shape observables such as quadrupole and octupole moments, we derive
fusion/fission probabilities, from which one can finally evaluate the
corresponding fusion and break-up cross sections. The dependence of the results
on shape, angular momentum and excitation energy is discussed.

We present optical, IR and millimeter observations of the solar-type star
13-277, also known as GM Cep, in the 4 Myr-old cluster Tr 37. GM Cep
experiences rapid magnitude variations of more than 2 mag at optical
wavelengths. We explore the causes of the variability, which seem to be
dominated by strong increases in the accretion, being similar to EX-or
episodes. The star shows high, variable accretion rates (up to ~10$^{-6}$
Msun/yr), signs of powerful winds, and it is a very fast rotator (Vsini~43
km/s). Its strong mid-IR excesses reveal a very flared disk and/or a remnant
envelope, most likely out of hydrostatic equilibrium. The 1.3 millimeter fluxes
suggest a relatively massive disk (Mdisk~0.1 Msun). Nevertheless, the
millimeter mass is not enough to sustain increased accretion episodes over
large timescales, unless the mass is underestimated due to significant grain
growth. We finally explore the possibility of GM Cep having a binary companion,
which could trigger disk instabilities producing the enhanced accretion
episodes.

The aim of this work is to provide a possible philosophical motivation to the
variational principles of physics in general and a possible way to unify the
axiomatizations of mechanics theories. The leitmotif of this work is a
dialectical view of the world: any smooth motion in nature is the consequence
of the interplay and dynamical balance between pairs of opposite elements of
the motion. We stress that the opposite property here differs from the common
sense of opposing elements (of conflicting appearance but of same nature) such
action/reaction forces between two bodies. The opposite elements here are
incompatible and mutual exclusive in nature, with contrasting and complementary
characteristics such as active/passive, disorder/order, curvature/flatness,
etc. The dynamical balance is defined by an invariant variational relationship
between all the pairs of opposite elements active in the considered motion.
From this idea, an axiomatization of quantum mechanics is proposed in addition
to the derivation of several existing variational principles of mechanics.

Theories suggest that filament fragmentation should occur on a characteristic
fragmentation length-scale. This fragmentation length-scale can be related to
filament properties, such as the width and the dynamical state of the filament.
Here we present a study of a number of fragmentation analysis techniques
applied to filaments, and their sensitivity to characteristic fragmentation
length-scales. We test the sensitivity to both single-tier and two-tier
fragmentation, i.e. when the fragmentation can be characterised with one or two
fragmentation length-scales respectively. The nearest neighbour separation,
minimum spanning tree separation and two-point correlation function are all
able to robustly detect characteristic fragmentation length-scales. The Fourier
power spectrum and the Nth nearest neighbour technique are both poor
techniques, and require very little scatter in the core spacings for the
characteristic length-scale to be successfully determined. We develop a null
hypothesis test to compare the results of the nearest neighbour and minimum
spanning tree separation distribution with randomly placed cores. We show that
a larger number of cores is necessary to successfully reject the null
hypothesis if the underlying fragmentation is two-tier, N>20. Once the null is
rejected we show how one may decide if the observed fragmentation is best
described by single-tier or two-tier fragmentation, using either Akaike's
information criterion or the Bayes factor. The analysis techniques, null
hypothesis tests, and model selection approaches are all included in a new
open-source Python/C library called FragMent.

Threw it Away 3min After Installation.
It seems to be almost impossible to find a decent S8 screen protector, and this item is no exception. They send it in nice packaging, but there is no way they don't know that they are selling garbage. The screen protector has a thin layer of adhesive solely around the edges, and you have to aggressively click on apps to open them.

Let $({\cal X},\|\:.\:\|)$ be a Banach space. In general, for a
$C_0$-semigroup \semi on $({\cal X},\|\:.\:\|)$, its adjoint semigroup \semia
is no longer strongly continuous on the dual space $({\cal
X}^{*},\|\:.\:\|^{*})$. Consider on ${\cal X}^{*}$ the topology of uniform
convergence on compact subsets of $({\cal X},\|\:.\:\|)$ denoted by ${\cal
C}({\cal X}^{*},{\cal X})$, for which the usual semigroups in literature
becomes $C_0$-semigroups. The main purpose of this paper is to prove that only
a core can be the domain of uniqueness for a $C_0$-semigroup on $({\cal
X}^{*},{\cal C}({\cal X}^{*},{\cal X}))$. As application, we show that the
generalized Schr\"odinger operator ${\cal A}^Vf={1/2}\Delta f+b\cdot\nabla
f-Vf$, $f\in C_0^\infty(\R^d)$, is $L^\infty(\R^d,dx)$-unique. Moreover, we
prove the $L^1(\R^d,dx)$-uniqueness of weak solution for the Fokker-Planck
equation associated with ${\cal A}^V$.

Not a nintendo controller but good enough
While this controller does not have the same button feel as the ones from Nintendo, it works just the same. The buttons are harder to push when compared but as long as you play with a heavier finger they work just fine. The longer cable is great and much appreciated.

Mass measurements on radionuclides along the potassium isotope chain have
been performed with the ISOLTRAP Penning trap mass spectrometer. For 35K
T1/2=178ms) to 46K (T1/2=105s) relative mass uncertainties of 2x10-8 and better
have been achieved. The accurate mass determination of 35K (dm=0.54keV) has
been exploited to test the Isobaric Multiplet Mass Equation (IMME) for the
A=35, T=3/2 isospinquartet. The experimental results indicate a deviation from
the generally adopted quadratic form.

Text classification is one of the most critical areas in machine learning and
artificial intelligence research. It has been actively adopted in many business
applications such as conversational intelligence systems, news articles
categorizations, sentiment analysis, emotion detection systems, and many other
recommendation systems in our daily life. One of the problems in supervised
text classification models is that the models' performance depends heavily on
the quality of data labeling that is typically done by humans. In this study,
we propose a new network community detection-based approach to automatically
label and classify text data into multiclass value spaces. Specifically, we
build networks with sentences as the network nodes and pairwise cosine
similarities between the Term Frequency-Inversed Document Frequency (TFIDF)
vector representations of the sentences as the network link weights. We use the
Louvain method to detect the communities in the sentence networks. We train and
test the Support Vector Machine and the Random Forest models on both the
human-labeled data and network community detection labeled data. Results showed
that models with the data labeled by the network community detection
outperformed the models with the human-labeled data by 2.68-3.75% of
classification accuracy. Our method may help developments of more accurate
conversational intelligence and other text classification systems.

We obtain high-velocity estimates with error bounds for the scattering
operator of the Schr\"odinger equation in three dimensions with electromagnetic
potentials in the exterior of bounded obstacles that are handlebodies. A
particular case is a finite number of tori. We prove our results with
time-dependent methods. We consider high-velocity estimates where the direction
of the velocity of the incoming electrons is kept fixed as its absolute value
goes to infinity. In the case of one torus our results give a rigorous proof
that quantum mechanics predicts the interference patterns observed in the
fundamental experiments of Tonomura et al. that gave a conclusive evidence of
the existence of the Aharonov-Bohm effect using a toroidal magnet. We give a
method for the reconstruction of the flux of the magnetic field over a
cross-section of the torus modulo $2\pi$. Equivalently, we determine modulo
$2\pi$ the difference in phase for two electrons that travel to infinity, when
one goes inside the hole and the other outside it. For this purpose we only
need the high-velocity limit of the scattering operator for one direction of
the velocity of the incoming electrons. When there are several tori -or more
generally handlebodies- the information that we obtain in the fluxes, and on
the difference of phases, depends on the relative position of the tori and on
the direction of the velocities when we take the high-velocity limit of the
incoming electrons. For some locations of the tori we can determine all the
fluxes modulo 2$\pi$ by taking the high-velocity limit in only one direction.
We also give a method for the unique reconstruction of the electric potential
and the magnetic field outside the handlebodies from the high-velocity limit of
the scattering operator.

PM Harper is a respected world statesman among the western liberal democracies and nowhere more highly than in Israel where he was the only Canadian PM and one of the only foreign leaders ever to be asked to address the Knesset and why he has received other high honours from the state of Israel.
He has founded a consulting form that aims to provide strategic and other advice to governments and major corporations that share the former PM`s values and goals.
So it makes sense that the former PM may very well have lined up a series of high level meetings to discuss possible consulting engagements with Israeli government and business leaders.
This, if it is the case, would require PM Harper to make his own travel arrangements according to his own schedule of meetings.
And travelling alone would provide the added and not inconsiderable benefit of not having to politely listen to hours of tedious and simplistic twaddle from the chap who replaced him as PM.
A real win-win situation!

Don’t expect to get the design or color selected!
I’ve ordered 4 different sets and styles. First style I ordered blue and got pink, the next never came and I got a refund. The third was suppose to be the designer blue ones and again came pink including the replacement I requested from amazon and the final set again suppose to be blue got lost, have not arrived, and working with amazon again to resolve. I understands colors/style may vary but when the title says boys I don’t expect pink with roses. While the cups themselves are amazing ordering from here is not. Super frustrating.

We show that for any convex differentiable loss, a deep linear network has no
spurious local minima as long as it is true for the two layer case. This
reduction greatly simplifies the study on the existence of spurious local
minima in deep linear networks. When applied to the quadratic loss, our result
immediately implies the powerful result in [Kawaguchi 2016]. Further, with the
work in [Zhou and Liang 2018], we can remove all the assumptions in [Kawaguchi
2016]. This property holds for more general "multi-tower" linear networks too.
Our proof builds on [Laurent and von Brecht 2018] and develops a new
perturbation argument to show that any spurious local minimum must have full
rank, a structural property which can be useful more generally.

Anisotropic cloud string cosmological model with Bianchi type I space time is
investigated in the context of general relativity. The exact solutions of
Einstein field equations are obtained with when the source for energy momentum
tensor is generated by a cloud of strings with particles attached to them. The
dynamical and physical properties of the model universe are discussed by
comparing with the present observational findings. The interesting feature
obtained here is that our model universe starts with a big bang and as time
passes both particle density and string tension density decreases with
expansion of our Universe so that in the late time string vanishes and thus
leaving only the particles.

I dig it!
I'm a bit late, but I think that might make a better review. I've had this holster for about five months, I carry a Sig Sauer P238 on the norm. It has held up quite nicely. The holster is comfortable, and sometimes I forget I'm wearing it. I would highly recommend this holster for anyone who owns a P238 or it's equivalent.

I am happy with these!
Exactly what I wanted! I am making ornaments for a memorial tree army wedding. I bought this pack and have enough of the smaller ornaments for what a needed and will use the extra bigger ones for other decor. They are good quality for the price. I am happy with them. They are sturdy, good colors and I love that they came with twine.

We consider a class of sequential network interdiction problem settings where
the interdictor has incomplete initial information about the network while the
evader has complete knowledge of the network including its structure and arc
costs. In each decision epoch, the interdictor can block (for the duration of
the epoch) at most $k$ arcs known to him/her. By observing the evader's
actions, the interdictor learns about the network structure and costs and thus,
can adjust his/her actions in subsequent decision epochs. It is known from the
literature that if the evader is greedy (i.e., the shortest available path is
used in each decision epoch), then under some assumptions the greedy
interdiction policies that block $k$-most vital arcs in each epoch are
efficient and have a finite regret. In this paper, we consider the evader's
perspective and explore deterministic "strategic" evasion policies under the
assumption that the interdictor is greedy. We first study the theoretical
computational complexity of the evader's problem. Then we derive basic
constructive properties of optimal evasion policies for two decision epochs
when the interdictor has no initial information about the network structure.
These properties are then exploited for the design of a heuristic algorithm for
a strategic evader in a general setting with an arbitrary time horizon and any
initial information available to the interdictor. Our computational experiments
demonstrate that the proposed heuristic outperforms the greedy evasion policy
on several classes of synthetic network instances under either perfect or noisy
information feedback. Finally, some interesting insights from our theoretical
and computational results conclude the paper.

Mapping the full Russian propaganda effort is important.
Yet investigators in the House, Senate, and special counsel Robert Mueller’s office are equally focused on a more explosive question: did any Americans help target the memes and fake news to crucial swing districts and wavering voter demographics?
“By Americans, you mean, like, the Trump campaign?” a source close to one of the investigations said with a dark laugh.

We study field theoretical models for cosmic (p,q)-superstrings in a curved
space-time. We discuss both string solutions, i.e. solutions with a conical
deficit, but also so-called Melvin solutions, which have a completely different
asymptotic behaviour. We show that globally regular gravitating (p,q)-strings
exist only in a finite domain of the parameter space and study the dependence
of the domain of existence on the parameters in the model. We find that due to
the interaction between strings, the parameter range where string solution
exist is wider than for non-interacting strings.

We study positive Liouville theorems and the asymptotic behavior of positive
solutions of p-Laplacian type elliptic equations of the form Q'(u):= -
pLaplace(u) + V |u|^{p-2} u = 0 in X, where X is a domain in R^d, d > 1, and
1<p<infty. We assume that the potential V has a Fuchsian type singularity at a
point zeta, where either zeta=infty and X is a truncated C^2-cone, or zeta=0
and zeta is either an isolated point of a boundary of X or belongs to a
C^2-portion of the boundary of X.

In inverse problems, the use of an $\ell_{12}$ analysis regularizer induces a
bias in the estimated solution. We propose a general refitting framework for
removing this artifact while keeping information of interest contained in the
biased solution. This is done through the use of refitting block penalties that
only act on the co-support of the estimation. Based on an analysis of related
works in the literature, we propose a new penalty that is well suited for
refitting purposes. We also present an efficient algorithmic method to obtain
the refitted solution along with the original (biased) solution for any convex
refitting block penalty. Experiments illustrate the good behavior of the
proposed block penalty for refitting.

Measurements of CMB temperature fluctuations by the Wilkinson Microwave
Anisotropy Probe (WMAP) indicate that the fluctuation amplitude in one half of
the sky differs from the amplitude in the other half. We show that such an
asymmetry cannot be generated during single-field slow-roll inflation without
violating constraints to the homogeneity of the Universe. In contrast, a
multi-field inflationary theory, the curvaton model, can produce this power
asymmetry without violating the homogeneity constraint. The mechanism requires
the introduction of a large-amplitude superhorizon perturbation to the curvaton
field, possibly a pre-inflationary remnant or a superhorizon curvaton-web
structure. The model makes several predictions, including non-Gaussianity and
modifications to the inflationary consistency relation, that will be tested
with forthcoming CMB experiments.

We consider a quark-lepton symmetry model of unification of the strong and
electromagnetic interactions. The model has the gauge group $SU(4)\times
U(1)_{Y}$ and the minimal Higgs structure consisting of one complex quartet of
scalar particles. The spontaneous breakdown of the gauge group to
$SU(3)_{c}\times U(1)_{em}$ due to nonzero vacuum expectation value of the
Higgs quartet provides the simplest realization of the Higgs mechanism which
generates masses for gauge bosons, and masses to quarks and leptons. Using the
embedding of the gauge group to SU(5), we study the evolution of coupling
constants and find a connection of the couplings with the gauge couplings of
the standard model.

Generative Adversarial Networks (GANs) are known to be difficult to train,
despite considerable research effort. Several regularization techniques for
stabilizing training have been proposed, but they introduce non-trivial
computational overheads and interact poorly with existing techniques like
spectral normalization. In this work, we propose a simple, effective training
stabilizer based on the notion of consistency regularization---a popular
technique in the semi-supervised learning literature. In particular, we augment
data passing into the GAN discriminator and penalize the sensitivity of the
discriminator to these augmentations. We conduct a series of experiments to
demonstrate that consistency regularization works effectively with spectral
normalization and various GAN architectures, loss functions and optimizer
settings. Our method achieves the best FID scores for unconditional image
generation compared to other regularization methods on CIFAR-10 and CelebA.
Moreover, Our consistency regularized GAN (CR-GAN) improves state-of-the-art
FID scores for conditional generation from 14.73 to 11.48 on CIFAR-10 and from
8.73 to 6.66 on ImageNet-2012.

A new 7-beam 6-7 GHz receiver has been built to survey the Galaxy and the
Magellanic Clouds for newly forming high-mass stars that are pinpointed by
strong methanol maser emission at 6668 MHz. The receiver was jointly
constructed by Jodrell Bank Observatory (JBO) and the Australia Telescope
National Facility (ATNF) and allows simultaneous coverage at 6668 and 6035 MHz.
It was successfully commissioned at Parkes in January 2006 and is now being
used to conduct the Parkes-Jodrell multibeam maser survey of the Milky Way.
This will be the first systematic survey of the entire Galactic plane for
masers of not only 6668-MHz methanol, but also 6035-MHz excited-state hydroxyl.
The survey is two orders of magnitude faster than most previous systematic
surveys and has an rms noise level of ~0.17 Jy.This paper describes the
observational strategy, techniques and reduction procedures of the Galactic and
Magellanic Cloud surveys, together with deeper, pointed, follow-up observations
and complementary observations with other instruments. It also includes an
estimate of the survey detection efficiency. The 111 days of observations with
the Parkes telescope have so far yielded >800 methanol sources, of which ~350
are new discoveries. The whole project will provide the first comprehensive
Galaxy-wide catalogue of 6668-MHz and 6035-MHz masers.

For every space $X$ let $\mathcal K(X)$ be the set of all compact subsets of
$X$. Christensen \cite{c:74} proved that if $X, Y$ are separable metrizable
spaces and $F\colon\mathcal{K}(X)\to\mathcal{K}(Y)$ is a monotone map such that
any $L\in\mathcal{K}(Y)$ is covered by $F(K)$ for some $K\in\mathcal{K}(X)$,
then $Y$ is complete provided $X$ is complete. It is well known \cite{bgp} that
this result is not true for non-separable spaces. In this paper we discuss some
additional properties of $F$ which guarantee the validity of Christensen's
result for more general spaces.

Physical keyboards are common peripherals for personal computers and are
efficient standard text entry devices. Recent research has investigated how
physical keyboards can be used in immersive head-mounted display-based Virtual
Reality (VR). So far, the physical layout of keyboards has typically been
transplanted into VR for replicating typing experiences in a standard desktop
environment.
In this paper, we explore how to fully leverage the immersiveness of VR to
change the input and output characteristics of physical keyboard interaction
within a VR environment. This allows individual physical keys to be
reconfigured to the same or different actions and visual output to be
distributed in various ways across the VR representation of the keyboard.
We explore a set of input and output mappings for reconfiguring the virtual
presentation of physical keyboards and probe the resulting design space by
specifically designing, implementing and evaluating nine VR-relevant
applications: emojis, languages and special characters, application shortcuts,
virtual text processing macros, a window manager, a photo browser, a
whack-a-mole game, secure password entry and a virtual touch bar. We
investigate the feasibility of the applications in a user study with 20
participants and find that, among other things, they are usable in VR. We
discuss the limitations and possibilities of remapping the input and output
characteristics of physical keyboards in VR based on empirical findings and
analysis and suggest future research directions in this area.

A product like this would be perfect to keep the heavy winds ...
I thought this would be a bit more practical or fashionable. There was a point in time where I walked to work every morning at 3AM in the dead of winter to open a coffee shop. A product like this would be perfect to keep the heavy winds off the face, however any other conditions this head covering is a bit much. Also, the head cover came WAY too large. The part meant to cover the mouth/chin would sag downward to my throat.

This program is a favorite of our family, and we feel it MUST be released on DVD by seasons!!! The title of "Promised Land" is very apt, as it is a positive statement about all the good that is left in this great country and the people who live in her! It's a "God Bless America" type of program with inspiring stories, old-fashioned values, down-to-earth characters, truthful and encouraging messages, beautiful scenery, and well-written humor and drama. It's a show the entire family is able to enjoy and benefit from--without worrying about bad language, "adult" themes, crudeness, violence, etc. We always felt blessed when we were done viewing an episode and can't wait to see each one all over again when they're finally released on DVD!

The emergence of new SARS-CoV-2 variants with enhanced transmissibility or decreased susceptibility to immune responses is a major threat to global efforts to end the coronavirus disease 2019 (COVID-19) pandemic. Disparities in viral genomic surveillance capabilities and efforts have resulted in gaps in our understanding of the viral population dynamics across the globe. Nigeria, despite having the largest population of any nation in Africa, has had relatively little SARS-CoV-2 sequence data made publicly available. Here we report the whole-genome sequences of 74 SARS-CoV-2 isolates collected from individuals in Oyo State, Nigeria in January 2021. Most isolates belonged to either the B.1.1.7 Alpha "variant of concern" or the B.1.525 Eta lineage, which is currently considered a "variant of interest" containing multiple spike protein mutations previously associated with enhanced transmissibility and possible immune escape. Nigeria has the highest reported frequency of the B.1.525 lineage globally with phylogenetic characteristics consistent with a recent monophyletic origin and rapid expansion. Spike protein from the B.1.525 lineage displayed both increased infectivity and decreased neutralization by convalescent sera compared to Spike proteins from other clades. These results, along with indications that the virus is outpacing the B.1.1.7 lineage in Nigeria, suggest that the B.1.525 lineage represents another "variant of concern" and further underline the importance of genomic surveillance in undersampled regions across the globe.

D\'ail \'Eireann is the principal chamber of the Irish parliament. The 31st
D\'ail \'Eireann is the principal chamber of the Irish parliament. The 31st
D\'ail was in session from March 11th, 2011 to February 6th, 2016. Many of the
members of the D\'ail were active on social media and many were Twitter users
who followed other members of the D\'ail. The pattern of following amongst
these politicians provides insights into political alignment within the D\'ail.
We propose a new model, called the generalized latent space stochastic
blockmodel, which extends and generalizes both the latent space model and the
stochastic blockmodel to study social media connections between members of the
D\'ail. The probability of an edge between two nodes in a network depends on
their respective class labels as well as latent positions in an unobserved
latent space. The proposed model is capable of representing transitivity,
clustering, as well as disassortative mixing. A Bayesian method with Markov
chain Monte Carlo sampling is proposed for estimation of model parameters.
Model selection is performed using the WAIC criterion and models of different
number of classes or dimensions of latent space are compared. We use the model
to study Twitter following relationships of members of the D\'ail and interpret
structure found in these relationships. We find that the following
relationships amongst politicians is mainly driven by past and present
political party membership. We also find that the modeling outputs are
informative when studying voting within the D\'ail.

I love these little lunchboxes and the product itself is excellent, however the company that ships these is RIDICULOUS and awful. I ordered two, clicked on a picture of a blue lunchbox. Noted in the notes in ordering I needed blue/ green type colors. Was delivered pink. Returned it and specified again blue/ green type colors. Received purple. The time I spent returning these items I could have bought one locally. DON'T BUY FROM THIS COMPANY unless you don't care what color you get.. and frankly for me I wouldn't buy from them based solely on such poor customer service.

Investigating the environment of the massive black hole SgrA* at the center
of the Galaxy requires the highest angular resolution available to avoid source
confusion and to study the physical properties of the individual objects.
GCIRS7 has been used as wavefront and astrometric reference. Our studies
investigate, for the first time, its properties at 2&10um using VLTI/AMBER and
MIDI. We aim at analyzing the suitability of IRS7 as an IF-phase-reference for
the upcoming generation of dual-field facilities at optical interferometers. We
observed with (R~30) and 50m (proj.) baseline, resulting in 9 and 45mas
resolution for NIR and MIR, resp. The first K-band fringe detection of a GC
star suggests that IRS7 could be marginally resolved at 2um, which would imply
that the photosphere of the supergiant is enshrouded by a molecular and dusty
envelope. At 10um, IRS7 is strongly resolved with a visibility of approximately
0.2. The MIR is dominated by moderately warm (200 K), extended dust, mostly
distributed outside of a radius of about 120 AU (15 mas) around the star. A
deep 9.8-silicate absorption in excess of the usual extinction law with respect
to the NIR extinction has been found. This confirms recent findings of a
relatively enhanced, interstellar 9.8-silicate absorption with respect to the
NIR extinction towards another star in the central arcsec, suggesting an
unusual dust composition in that region. Our VLTI observations show that
interferometric NIR phase-referencing experiments with mas resolution using
IRS7 as phase-reference appear to be feasible, but more such studies are
required to definitely characterize the close environment around this star. We
demonstrate that interferometry is required to resolve the innermost
environment of stars at the Galactic center.

THESE FRAMES DEFINE CHEAP/TRASH!!!!
DO NOT BUY this product. The frames horrible all around. Just go to the gas station and buy a pair, you'll probably get better quality. I'm glad I only wasted $14. Don't believe me.....buy the glasses and see for yourself. ANYONE who says these frames are good is full of shit! These frames SUCK!!!!!!

Pure exploration (aka active testing) is the fundamental task of sequentially
gathering information to answer a query about a stochastic environment. Good
algorithms make few mistakes and take few samples. Lower bounds (for
multi-armed bandit models with arms in an exponential family) reveal that the
sample complexity is determined by the solution to an optimisation problem. The
existing state of the art algorithms achieve asymptotic optimality by solving a
plug-in estimate of that optimisation problem at each step. We interpret the
optimisation problem as an unknown game, and propose sampling rules based on
iterative strategies to estimate and converge to its saddle point. We apply
no-regret learners to obtain the first finite confidence guarantees that are
adapted to the exponential family and which apply to any pure exploration query
and bandit structure. Moreover, our algorithms only use a best response oracle
instead of fully solving the optimisation problem.

The principle of optimizing inequalities, or their equivalent operator
theoretic formulation, is well established in analysis. For an operator, this
corresponds to extending its action to larger domains, hopefully to the largest
possible such domain (i.e, its \textit{optimal domain}). Some classical
operators are already optimally defined (e.g., the Hilbert transform in
$L^p(\mathbb{R})$, $1<p<\infty$) and others are not (e.g., the Hausdorff-Young
inequality in $L^p(\mathbb{T})$, $1<p<2$, or Sobolev's inequality in various
spaces). In this paper a detailed investigation is undertaken of the finite
Hilbert transform $T$ acting on rearrangement invariant spaces $X$ on $(-1,1)$,
an operator whose singular kernel is neither positive nor does it possess any
monotonicity properties. For a large class of such spaces $X$ it is shown that
$T$ is already optimally defined on $X$ (this is known for $L^p(-1,1)$ for all
$1<p<\infty$, except $p=2$). The case $p=2$ is significantly different because
the range of $T$ is a proper dense subspace of $L^2(-1,1)$. Nevertheless, by a
completely different approach, it is established that $T$ is also optimally
defined on $L^2(-1,1)$. Our methods are also used to show that the solution of
the airfoil equation, which is well known for the spaces $L^p(-1,1)$ whenever
$p\not=2$ (due to certain properties of $T$), can also be extended to the class
of r.i.\ spaces $X$ considered in this paper.

In this paper we present an efficient and robust approach to compute a
normalized B-spline-like basis for spline spaces with pieces drawn from
extended Tchebycheff spaces. The extended Tchebycheff spaces and their
dimensions are allowed to change from interval to interval. The approach works
by constructing a matrix that maps a generalized Bernstein-like basis to the
B-spline-like basis of interest. The B-spline-like basis shares many
characterizing properties with classical univariate B-splines and may easily be
incorporated in existing spline codes. This may contribute to the full
exploitation of Tchebycheffian splines in applications, freeing them from the
restricted role of an elegant theoretical extension of polynomial splines.
Numerical examples are provided that illustrate the procedure described.

In this paper we discuss optimal dispatching of fire trucks, based on a
particular dispatching problem that arises at the Amsterdam Fire Department,
where two fire trucks are send to the same incident location for a quick
response. We formulate the dispatching problem as a Markov Decision Process,
and numerically obtain the optimal dispatching decisions using policy
iteration. We show that the fraction of late arrivals can be significantly
reduced by deviating from current practice of dispatching the closest available
trucks, with a relative improvement of on average about $20\%$, and over $50\%$
for certain instances. We also show that driving-time correlation has a
non-negligible impact on decision making, and if ignored may lead to
performance decrease of over $20\%$ in certain cases. As the optimal policy
cannot be computed for problems of realistic size due to the computational
complexity of the policy iteration algorithm, we propose a dispatching
heuristic based on a queueing approximation for the state of the network. We
show that the performance of this heuristic is close to the optimal policy, and
requires significantly less computational effort.

$\DeclareMathOperator{\Aut}{Aut}$Let $p, q$ be distinct primes, with $p > 2$.
We classify the Hopf-Galois structures on Galois extensions of degree $p^{2}
q$, such that the Sylow $p$-subgroups of the Galois group are cyclic. This we
do, according to Greither and Pareigis, and Byott, by classifying the regular
subgroups of the holomorphs of the groups $(G, \cdot)$ of order $p^{2} q$, in
the case when the Sylow $p$-subgroups of $G$ are cyclic. This is equivalent to
classifying the skew braces $(G, \cdot, \circ)$.
Furthermore, we prove that if $G$ and $\Gamma$ are groups of order $p^{2} q$
with non-isomorphic Sylow $p$-subgroups, then there are no regular subgroups of
the holomorph of $G$ which are isomorphic to $\Gamma$. Equivalently, a Galois
extension with Galois group $\Gamma$ has no Hopf-Galois structures of type $G$.
Our method relies on the alternate brace operation $\circ$ on $G$, which we
use mainly indirectly, that is, in terms of the functions $\gamma : G \to
\Aut(G)$ defined by $g \mapsto (x \mapsto (x \circ g) \cdot g^{-1})$. These
functions are in one-to-one correspondence with the regular subgroups of the
holomorph of $G$, and are characterised by the functional equation
$\gamma(g^{\gamma(h)} \cdot h) = \gamma(g) \gamma(h)$, for $g, h \in G$. We
develop methods to deal with these functions, with the aim of making their
enumeration easier, and more conceptual.

This work generalizes the results of an earlier paper by the second author,
from Randers metrics to $(\alpha,\beta)$-metrics. Let $F$ be an
$(\alpha,\beta)$-metric which is defined by a left invariant vector field and a
left invariant Riemannian metric on a simply connected real Lie group $G$. We
consider the automorphism and isometry groups of the Finsler manifold $(G,F)$
and their intersection. We prove that for an arbitrary left invariant vector
field $X$ and any compact subgroup $K$ of automorphisms which $X$ is invariant
under them, there exists an $(\alpha,\beta)$-metric such that $K$ is a subgroup
of its isometry group.

The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a
hardware simulator for wavefront sensing and control designed to produce
JWST-like images. A model of the JWST three mirror anas- tigmat is realized
with three lenses in the form of a Cooke triplet, which provides JWST-like
optical quality over a field equivalent to a NIRCam module. An Iris AO
hexagonally segmented mirror stands in for the JWST primary. This setup
successfully produces images extremely similar to expected JWST in-flight point
spread functions (PSFs), and NIRCam images from cryotesting, in terms of the
PSF morphology and sampling relative to the diffraction limit. The segmentation
of the primary mirror into subapertures introduces complexity into wavefront
sensing and control (WFS&C) of large space based telescopes like JWST. JOST
provides a platform for independent analysis of WFS&C scenarios for both
commissioning and maintenance activities on such ob- servatories. We present an
update of the current status of the testbed including both single field and
wide-field alignment results. We assess the optical quality of JOST over a wide
field of view to inform the future imple- mentation of different wavefront
sensing algorithms including the currently implemented Linearized Algorithm for
Phase Diversity (LAPD). JOST complements other work at the Makidon Laboratory
at the Space Telescope Science Institute, including the High-contrast imager
for Complex Aperture Telescopes (HiCAT) testbed, that investigates coronagraphy
for segmented aperture telescopes. Beyond JWST we intend to use JOST for WFS&C
studies for future large segmented space telescopes such as LUVOIR.

The $T\bar T$ deformation of a conformal field theory has a dual description
as a cutoff $AdS_3$ spacetime, at least at the level of pure 3d gravity. We
generalize this deformation in such a way that it builds up a patch of bulk
$dS_3$ spacetime instead. At each step along the trajectory in the space of
$2d$ theories, the theory is deformed by a specific combination of $T\bar T$
and the two-dimensional cosmological constant. This provides a concrete
holographic dual for the warped throat on the gravity side of the dS/dS
duality, at leading order in large central charge. We also analyze a sequence
of excitations of this throat on both sides of the duality, as well as the
entanglement entropy. Our results point toward a mechanism for obtaining de
Sitter solutions starting from seed conformal field theories with AdS duals.

We present a new approach for pretraining a bi-directional transformer model
that provides significant performance gains across a variety of language
understanding problems. Our model solves a cloze-style word reconstruction
task, where each word is ablated and must be predicted given the rest of the
text. Experiments demonstrate large performance gains on GLUE and new state of
the art results on NER as well as constituency parsing benchmarks, consistent
with the concurrently introduced BERT model. We also present a detailed
analysis of a number of factors that contribute to effective pretraining,
including data domain and size, model capacity, and variations on the cloze
objective.

Using the quasi-Maxwell formalism, we derive the necessary and sufficient
conditions for the matching of two stationary spacetimes along a stationary
timelike hypersurface, expressed in terms of the gravitational and
gravitomagnetic fields and the 2-dimensional matching surface on the space
manifold. We prove existence and uniqueness results to the matching problem for
stationary perfect fluid spacetimes with spherical, planar, hyperbolic and
cylindrical symmetry. Finally, we find an explicit interior for the cylindrical
analogue of the NUT spacetime.

N. Katz introduced the notion of the middle convolution on local systems.
This can be seen as a generalization of the Euler transform of Fuchsian
differential equations. In this paper, we consider the generalization of the
Euler transform, the twisted Euler transform, and apply this to differential
equations with irregular singular points. In particular, for differential
equations with an irregular singular point of irregular rank 2 at $x=\infty$,
we describe explicitly changes of local datum caused by twisted Euler
transforms. Also we attach these differential equations to Kac-Moody Lie
algebras and show that twisted Euler transforms correspond to the action of
Weyl groups of these Lie algebras.

What a shocker. For starters, I couldn't stand the constant screaming and noisy panicking all the time. It didn't make me scared, horrified, or make me sympathetic towards the characters; it was simply annoying. The jerky camera movements were also annoying. The plot was the same as pretty much every other cheap horror. There was a few pathetic attempts to give the characters some depth, but it didn't really work into the rest of the plot. And then there's the ending. I'm still not really sure what to make of it. I guess it was supposed to be clever twist, then shed some light on the situation, but it was just stupid.<br /><br />The case had a couple of those little award winner/nominations symbols on it, so I figured it couldn't be too bad. I was wrong. If you see it, you should probably just leave it on the shelf.

Multimodal interfaces, combining the use of speech, graphics, gestures, and
facial expressions in input and output, promise to provide new possibilities to
deal with information in more effective and efficient ways, supporting for
instance: - the understanding of possibly imprecise, partial or ambiguous
multimodal input; - the generation of coordinated, cohesive, and coherent
multimodal presentations; - the management of multimodal interaction (e.g.,
task completion, adapting the interface, error prevention) by representing and
exploiting models of the user, the domain, the task, the interactive context,
and the media (e.g. text, audio, video). The present document is intended to
support the discussion on multimodal content representation, its possible
objectives and basic constraints, and how the definition of a generic
representation framework for multimodal content representation may be
approached. It takes into account the results of the Dagstuhl workshop, in
particular those of the informal working group on multimodal meaning
representation that was active during the workshop (see
http://www.dfki.de/~wahlster/Dagstuhl_Multi_Modality, Working Group 4).

We compute the macroscopic entropy of the supersymmetric rotating dyonic
strings carrying linear momentum in 6D (1,0) supergravity with curvature
squared corrections. Our calculation is based on Sen's entropy function
formalism applied to the near-horizon geometry of the string solution taking
the form of an extremal BTZ$\times S^3$. The final entropy formula states that
the two independent supersymmetric completions of Riemann tensor squared
contribute equally to the entropy. A further $S^3$ compactification of the 6D
theory results in a matter coupled 3D supergravity model in which the
quantization condition of the SU(2)$_R$ Chern-Simons level implies the horizon
value of the dilaton is not modified by higher derivative interactions beyond
supersymmetric curvature squared terms.
