Some people have made a point of dissing this movie because they question the plausibility of black people in the Old West, Asian people in the Old West or women with guns in the Old West period. Get a grip and read a book. There were quite a few Asians (Chinese), there were quite a few blacks (freedmen) and everybody outside of the gentile class had ready access to guns; it is the second amendment you know. And as far as the use of modern language goes, none of those Westerns people have waxed nostalgic about actually used language that was consistent with the era depicted. Americans had different accents, used different inflections, spoke at a very different pace and used plenty of words and phrases that would be unrecognizable today. Don't blame historical inaccuracy for the fact that you just didn't dig it. Be honest. Maybe you're just uncomfortable with what you're seeing.

Using simulations we identify three dynamic regimes in supersaturated
isotropic fluid states of short hard rods: (i) for moderate supersaturations we
observe nucleation of multi-layered crystalline clusters; (ii) at higher
supersaturation, we find nucleation of small crystallites which arrange into
long-lived locally favored structures that get kinetically arrested, while
(iii) at even higher supersaturation the dynamic arrest is due to the
conventional cage-trapping glass transition. For longer rods we find that the
formation of the (stable) smectic phase out of a supersaturated isotropic state
is strongly suppressed by an isotropic-nematic spinodal instability that causes
huge spinodal-like orientation fluctuations with nematic clusters diverging in
size. Our results show that glassy dynamics and spinodal instabilities set
kinetic limits to nucleation in a highly supersaturated hard-rod fluids.

The performance of millimeter wave (mmWave) multiple-input multiple-output
(MIMO) systems is limited by the sparse nature of propagation channels and the
restricted number of radio frequency (RF) chains at transceivers. The
introduction of reconfigurable antennas offers an additional degree of freedom
on designing mmWave MIMO systems. This paper provides a theoretical framework
for studying the mmWave MIMO with reconfigurable antennas. Based on the virtual
channel model, we present an architecture of reconfigurable mmWave MIMO with
beamspace hybrid analog-digital beamformers and reconfigurable antennas at both
the transmitter and the receiver. We show that employing reconfigurable
antennas can provide throughput gain for the mmWave MIMO. We derive the
expression for the average throughput gain of using reconfigurable antennas in
the system, and further derive the expression for the outage throughput gain
for the scenarios where the channels are (quasi) static. Moreover, we propose a
low-complexity algorithm for reconfiguration state selection and beam
selection. Our numerical results verify the derived expressions for the
throughput gains and demonstrate the near-optimal throughput performance of the
proposed low-complexity algorithm.

The electronic structure of In$_{2-x}$V$_x$O$_3$ ($x=0.08$) has been
investigated using photoemission spectroscopy (PES) and x-ray absorption
spectroscopy (XAS). The V $2p$ core-level PES and XAS spectra revealed
trivalent electronic state of the V ion, consistent with the substitution of
the V ion for the In site. The V 3d partial density of states obtained by the
resonant PES technique showed a sharp peak above the O $2p$ band. While the O
$1s$ XAS spectrum of In$_{2-x}$V$_x$O$_3$ was similar to that of In$_2$O$_3$,
there were differences in the In $3p$ and 3d XAS spectra between V-doped and
pure In$_2$O$_3$. The observations give clear evidence for hybridization
between the In conduction band and the V 3d orbitals in In$_{2-x}$V$_x$O$_3$.

Expert human drivers perform actions relying on traffic laws and their
previous experience. While traffic laws are easily embedded into an artificial
brain, modeling human complex behaviors which come from past experience is a
more challenging task. One of these behaviors is the capability of
communicating intentions and negotiating the right of way through driving
actions, as when a driver is entering a crowded roundabout and observes other
cars movements to guess the best time to merge in. In addition, each driver has
its own unique driving style, which is conditioned by both its personal
characteristics, such as age and quality of sight, and external factors, such
as being late or in a bad mood. For these reasons, the interaction between
different drivers is not trivial to simulate in a realistic manner. In this
paper, this problem is addressed by developing a microscopic simulator using a
Deep Reinforcement Learning Algorithm based on a combination of visual frames,
representing the perception around the vehicle, and a vector of numerical
parameters. In particular, the algorithm called Asynchronous Advantage
Actor-Critic has been extended to a multi-agent scenario in which every agent
needs to learn to interact with other similar agents. Moreover, the model
includes a novel architecture such that the driving style of each vehicle is
adjustable by tuning some of its input parameters, permitting to simulate
drivers with different levels of aggressiveness and desired cruising speeds.

When his elderly mother Emily (Jeanne Bates) is attacked by her lodger Nestor Duvalier (Brion James) and turns into a cannibalistic monster, TV news reporter Clay Dwyer (Mark Thomas Miller) struggles to keep dear old mom from satisfying her hunger.<br /><br />Although the above plot summary conjures up images of trashy, over-the-top, 80s horror titles such as Flesheating Mothers and Rabid Grannies, Mom actually turns out to be a refreshingly original take on the werewolf/vampire/zombie mythos (exactly what Emily becomes is never really clear, but it ain't nice!), as well as a touching study of the close bond between mother and son: Clay's devotion to his mother leads him to abandon all of his other responsibilities, including his job and his relationship with pregnant girlfriend Alice (Mary Beth McDonough), whilst Emily's love for Clay ultimately drives her to self-destruction.<br /><br />Technically, the film could be sharper, with more stylish direction and better effects (the shots of the creature are kept very brief, so as not to disappoint), and certain more experienced members of the cast frustrate with terribly cheesy performances (Yes, Brion James and Stella Stevens, I AM referring to you); fortunately, however, the strong emotional undercurrent in the well constructed story is enough on its own to ensure that Mom is an effective, compelling, and occasionally shocking taleone which I have no hesitation in recommending to those looking for something a little different.

We investigate the relation between mobility and diffusivity for Brownian
particles under steady shear near the glass transition, using mode coupling
approximations. For the two directions perpendicular to the shear direction,
the particle motion is diffusive at long times and the mobility reaches a
finite constant. Nevertheless, the Einstein relation holds only for the
short-time in-cage motion and is violated for long times. In order to get the
relation between diffusivity and mobility, we perform the limit of small
wavevector for the relations derived previously [Phys. Rev. Lett. 102 (2009),
135701], without further approximation. We find good agreement to simulation
results. Furthermore, we split the extra term in the mobility in an exact way
into three terms. Two of them are expressed in terms of mean squared
displacements. The third is given in terms of the (less handy) force-force
correlation function.

We show how to combine the light-cone and matrix product algorithms to
simulate quantum systems far from equilibrium for long times. For the case of
the XXZ spin chain at $\Delta=0.5$, we simulate to a time of $\approx 22.5$.
While part of the long simulation time is due to the use of the light-cone
method, we also describe a modification of the iTEBD algorithm with improved
numerical stability, and we describe how to incorporate symmetry into this
algorithm. While statistical sampling error means that we are not yet able to
make a definite statement, the behavior of the simulation at long times
indicates the appearance of either "revivals" in the order parameter as
predicted previously or of a distinct shoulder in the decay of the order
parameter.

"loose talk"????
I'll have you know, NP5491, that I chose those words very, very carefully.
I watched, I thought about it, and I came to the conclusion that Trump is an idiot.
Just because well foundationed, rational and justifiable description doesn't fit into your fantasies of a world actually ruled by Trump, doesn't mean they aren't well foundationed, rational and justifiable.
One defintion of idiot in the Merriam-Webster Dictionary is:
"a foolish or stupid person"
So, relative to firing Comey, Trump was both stupid and foolish. Evidence? Mueller, Bannon and general ongoing controversy.
Relative to new smear campaign against Comey? Stupid and foolish. The talkiing points miss the pint, but more importantly, they re-raise how stupid and foolish he was to fire Comey in the first place. Lester Holt's interview gets more views on Youtube.
Plus, just overall, he's stupid and foolish. So, idiot. And, also idiotic. For his idiotness (A word? You can criticize if not).

In this article, a practical procedure for absolute intensity calibration for
SAXS studies on liquid microjets is established, using a gold nanoparticle
suspension as standard so that the intercept at $Q=0$ of the SAXS scattering
curve would provide a scaling reference. In order to get the most precise
extrapolation at $Q=0$, we used an extension to the Guinier approximation, with
a second-order term in the fit that adapts to a larger $Q$-range.

A central issue in molecular orbital theory is to compute the HOMO-LUMO gap
of a molecule, which measures the excitability of the molecule. Thus it would
be of interest to learn how to construct a molecule with the prescribed
HOMO-LUMO gap. In this paper, we classify all possible structures of fullerene
Cayley graphs and compute their spectrum. For any natural number $n$ not
divisible by three, we show there exists an infinite family of fullerene graphs
with the same HOMO-LUMO gap of size $\frac{2\pi}{\sqrt{3}n}+O(n^{-2})$.
Finally, we discuss how to realize those families in three dimensional space.

CHENNAI: Upset after his wife left for her mother’s home following a quarrel, a man cut his genitals at his house in New Washermenpet on Tuesday night.
Police said Babu, 40, of Tsunami Quarters was married to Devi, 35. The couple were childless and would often pick fights over it. The woman also did not like her husband getting sloshed.
Police said Devi sought a divorce from Babu and left for her mother’s home on Monday. However, she returned to celebrate the New Year on Tuesday when a quarrel broke out over Babu consuming liquor. Devi left for her mother’s house again.
Upset, Babu went to the kitchen and cut his genitals with a knife. Hearing his cries, neighbours rushed him to Government Stanley Medical College and Hospital. Police said his condition is critical.

Deformation-induced lateral migration of a bubble slowly rising near a
vertical plane wall in a stagnant liquid is numerically and theoretically
investigated. In particular, our focus is set on a situation with a small
clearance $c$ between the bubble interface and the wall. Motivated by the fact
that experimentally measured migration velocity (Takemura et al. (2002, J.
Fluid Mech. {\bf 461}, 277)) is higher than the velocity estimated by the
available analytical solution (Magnaudet et al. (2003, J. Fluid Mech. {\bf
476}, 115)) using the Fax\'{e}n mirror image technique for $\kappa(=a/(a+c))\ll
1$ (here $a$ is the bubble radius), when the clearance parameter
$\epsilon(=c/a)$ is comparable to or smaller than unit, the numerical analysis
based on the boundary-fitted finite-difference approach by solving the Stokes
equation is performed to complement the experiment. To improve the
understandings of a role of the squeezing flow within the bubble-wall gap, the
theoretical analysis based on a soft-lubrication approach (Skotheim & Mahadevan
(2004, Phys. Rev. Lett. {\bf 92}, 245509)) is also performed. The present
analyses demonstrate the migration velocity scales $\propto{\rm Ca}\
\epsilon^{-1}V_{B1}$ (here, $V_{B1}$ and ${\rm Ca}$ denote the rising velocity
and the capillary number, respectively) in the limit of $\epsilon\to 0$.

This paper reports the result of our evaluation of the tenth-order QED
correction to the lepton g-2 from Feynman diagrams which have sixth-order
light-by-light-scattering subdiagrams, none of whose vertices couple to the
external magnetic field. The gauge-invariant set of these diagrams, called Set
II(e), consists of 180 vertex diagrams. In the case of the electron g-2 (a_e),
where the light-by-light subdiagram consists of the electron loop, the
contribution to a_e is found to be - 1.344 9 (10) (\alpha /\pi)^5. The
contribution of the muon loop to a_e is - 0.000 465 (4) (\alpha /\pi)^5. The
contribution of the tau-lepton loop is about two orders of magnitudes smaller
than that of the muon loop and hence negligible. The sum of all of these
contributions to a_e is - 1.345 (1) (\alpha /\pi)^5. We have also evaluated the
contribution of Set II(e) to the muon g-2 (a_\mu). The contribution to a_\mu
from the electron loop is 3.265 (12) (\alpha /\pi)^5, while the contribution of
the tau-lepton loop is -0.038 06 (13) (\alpha /\pi)^5. The total contribution
to a_\mu, which is the sum of these two contributions and the mass-independent
part of a_e, is 1.882 (13) (\alpha /\pi)^5.

We discuss chiral perturbation theory for two and three quark flavors in the
epsilon expansion at next-to-next-to-leading order (NNLO) including a small
imaginary chemical potential. We calculate finite-volume corrections to the
low-energy constants $\Sigma$ and $F$ and determine the non-universal
modifications of the theory, i.e., modifications that cannot be mapped to
random matrix theory (RMT). In the special case of two quark flavors in an
asymmetric box we discuss how to minimize the finite-volume corrections and
non-universal modifications by an optimal choice of the lattice geometry.
Furthermore we provide a detailed calculation of a special version of the
massless sunset diagram at finite volume.

In this article we obtain a fundamental measure functional for the model of
aligned hard hexagons in the plane. Our aim is not just to provide a functional
for a new, admittedly academic, model, but to investigate the structure of
fundamental measure theory. A model of aligned hard hexagons has similarities
with the hard disk model. Both share "lost cases", i.e. admit configurations of
three particles in which there is pairwise overlap but not triple overlap.
These configurations are known to be problematic for fundamental measure
functionals, which are not able to capture their contribution correctly. This
failure lies in the inability of these functionals to yield a correct low
density limit of the third order direct correlation function. Here we derive
the functional by projecting aligned hard cubes on the plane x+y+z=0. The
correct dimensional crossover behavior of these functionals permits us to
follow this strategy. The functional of aligned hard cubes, however, does not
have lost cases, so neither had the resulting functional for aligned hard
hexagons. The latter exhibits, in fact, a peculiar structure as compared to the
one for hard disks. It depends on a uniparametric family of weighted densities
through a new term not appearing in the functional for hard disks. Apart from
studying the freezing of this system, we discuss the implications of the
functional structure for new developments of fundamental measure theory.

Given a stream $S = (s_1, s_2, ..., s_N)$, a $\phi$-heavy hitter is an item
$s_i$ that occurs at least $\phi N$ times in $S$. The problem of finding
heavy-hitters has been extensively studied in the database literature. In this
paper, we study a related problem. We say that there is a $\phi$-event at time
$t$ if $s_t$ occurs exactly $\phi N$ times in $(s_1, s_2, ..., s_t)$. Thus, for
each $\phi$-heavy hitter there is a single $\phi$-event which occurs when its
count reaches the reporting threshold $\phi N$. We define the online
event-detection problem (OEDP) as: given $\phi$ and a stream $S$, report all
$\phi$-events as soon as they occur.
Many real-world monitoring systems demand event detection where all events
must be reported (no false negatives), in a timely manner, with no non-events
reported (no false positives), and a low reporting threshold. As a result, the
OEDP requires a large amount of space (Omega(N) words) and is not solvable in
the streaming model or via standard sampling-based approaches.
Since OEDP requires large space, we focus on cache-efficient algorithms in
the external-memory model.
We provide algorithms for the OEDP that are within a log factor of optimal.
Our algorithms are tunable: its parameters can be set to allow for a bounded
false-positives and a bounded delay in reporting. None of our relaxations allow
false negatives since reporting all events is a strict requirement of our
applications. Finally, we show improved results when the count of items in the
input stream follows a power-law distribution.

Works for a car, annoying for an outlet.
Well, it does what it’s supposed to do. It recharges my phone in the car and from my home outlets. But, when I plug it into a wall outlet the prongs keep falling back flat. I need to hold them up and try to insert them at the same time. Very awkward and annoying. Also, it’s not an ideal design. Because of its shape it always covers the second portion of the outlet. You can’t turn it upside down because of the shaped prongs.

Rare events attract more attention and interests in many scenarios of big
data such as anomaly detection and security systems. To characterize the rare
events importance from probabilistic perspective, the message importance
measure (MIM) is proposed as a kind of semantics analysis tool. Similar to
Shannon entropy, the MIM has its special functional on information processing,
in which the parameter $\varpi$ of MIM plays a vital role. Actually, the
parameter $\varpi$ dominates the properties of MIM, based on which the MIM has
three work regions where the corresponding parameters satisfy $ 0 \le \varpi
\le 2/\max\{p(x_i)\}$, $\varpi > 2/\max\{p(x_i)\}$ and $\varpi < 0$
respectively. Furthermore, in the case $ 0 \le \varpi \le 2/\max\{p(x_i)\}$,
there are some similarity between the MIM and Shannon entropy in the
information compression and transmission, which provide a new viewpoint for
information theory. This paper first constructs a system model with message
importance measure and proposes the message importance loss to enrich the
information processing strategies. Moreover, we propose the message importance
loss capacity to measure the information importance harvest in a transmission.
Furthermore, the message importance distortion function is presented to give an
upper bound of information compression based on message importance measure.
Additionally, the bitrate transmission constrained by the message importance
loss is investigated to broaden the scope for Shannon information theory.

Matrix models of Yang-Mills type lead to an emergent gravity theory, which
may not require fine-tuning of a cosmological constant. We find cosmological
solutions of Friedmann-Robertson-Walker type. They generically have a big
bounce, and an early inflation-like phase with graceful exit. The mechanism is
purely geometrical, no ad-hoc scalar fields are introduced. The solutions are
stabilized through vacuum fluctuations and are thus compatible with quantum
mechanics. This leads to a Milne-like universe after inflation, which appears
to be in remarkably good agreement with observation and may provide an
alternative to standard cosmology.

In this paper we completely describe the order isomorphisms between cones of
atomic JBW-algebras. Moreover, we can write an atomic JBW-algebra as an
algebraic direct summand of the so-called engaged and disengaged part. On the
cone of the engaged part every order isomorphism is linear and the disengaged
part consists only of copies of $\mathbb{R}$. Furthermore, in the setting of
general JB-algebras we prove the following. If either algebra does not contain
an ideal of codimension one, then every order isomorphism between their cones
is linear if and only if it extends to a homeomorphism, between the cones of
the atomic part of their biduals, for a suitable weak topology.

Before I comment above. You Joni...are wrong. President Trump respects the military. What a hard call to make. You have plenty to say about what is wrong with Trump...but how about Wilson "Now I'm a Rock Star". How about that...get her fame and fortune off the backs of a soldier who died for his country so she (Wilson) COULD OPEN HER BIG FAT YAP. Read it again...I don't see anything inarticulate about what he said. Further...It was a Gold Star Father, i.e., General Kelly that was the most hurt by Wilson's insensitive remarks.

We study a flavor model that the quark sector has the $S_3$ modular
symmetry,while the lepton sector has the $A_4$ modular symmetry. Our model
leads to characteristic quark mass matrices which are consistent with
experimental data of quark masses, mixing angles and the CP violating phase.
The lepton sector is also consistent with the experimental data of neutrino
oscillations. We also study baryon and lepton number violations in our flavor
model.

We derive analytic formulas for the radiation power output when electrons are
accelerated by a relativistic comoving kinetic Poynting flux, and validate
these analytic results with Particle-In-Cell simulations. We also derive
analytically the critical frequency of the radiation spectrum. Potential
astrophysical applications of these results are discussed. A quantitative model
of gamma-ray bursts based on the breakout of kinetic Poynting flux is
presented.

Mr. Bean has always been my favorite. No matte how many times you watch the same thing, the show never gets monotonous or repetitive. Mr. Bean is one of the greatest comedians in the world who doesn't need to even speak to make people laugh. His gestures, his facial expressions and his face itself is so funny to watch. The situations which he faces on the show is simply hilarious and the way he handles them is even greater. There is simply no reason why this show shouldn't receive a 10 because it is fabulous. Its something that would even make the most serious or sad person in the universe laugh. Some of my all time favorites episodes from the show are: 1) When Mr. Bean lodges at a hotel 2) The one where he watches the scary film 3) Mind the baby ( The diaper scene especially). In fact, all the episodes are so good that it is really difficult to criticize the show. Mr.Bean can go to any heights to prove that he is funny, including completely stripping himself in one of the episodes. the way he handled that situation was simply mind blowing. 10 out of 10.

Human crowd motion is mainly driven by self-organized processes based on
local interactions among pedestrians. While most studies of crowd behavior
consider only interactions among isolated individuals, it turns out that up to
70% of people in a crowd are actually moving in groups, such as friends,
couples, or families walking together. These groups constitute medium-scale
aggregated structures and their impact on crowd dynamics is still largely
unknown. In this work, we analyze the motion of approximately 1500 pedestrian
groups under natural condition, and show that social interactions among group
members generate typical group walking patterns that influence crowd dynamics.
At low density, group members tend to walk side by side, forming a line
perpendicular to the walking direction. As the density increases, however, the
linear walking formation is bent forward, turning it into a V-like pattern.
These spatial patterns can be well described by a model based on social
communication between group members. We show that the V-like walking pattern
facilitates social interactions within the group, but reduces the flow because
of its "non-aerodynamic" shape. Therefore, when crowd density increases, the
group organization results from a trade-off between walking faster and
facilitating social exchange. These insights demonstrate that crowd dynamics is
not only determined by physical constraints induced by other pedestrians and
the environment, but also significantly by communicative, social interactions
among individuals.

The subject is banal, even in 1942. It is war propaganda. The fascists are among us and they are doing all they can to sabotage the war effort and to prepare their victory and their seizure of power then and their establishing an effective totalitarian state. But Hitchcock has to make it a real thriller. So he invents a first sabotage that succeeds but one of the victims, the friend of the one who dies in it, becomes the prime suspect and run-away for the sabotage. That enables him to so-to-say visit the country and discover the tricky organization of the local Nazis who have acquaintances and support in the top benevolent society and use the small little dissatisfied whites to do the dirty work. The chase after the real saboteur takes our young false suspect from Los Angeles to New York and to the top of the organization. He meets a blind pianist who believes his senses to know the chap is not guilty, his niece who is a star of the advertising billboard but also a frenetic and fanatic patriot who only thinks of going to the police. Then the rich rancher and his nest of plotters. Then, on the road some sympathetic and friendly truck driver, and the long caravan of a circus going around and their dwarf, bearded woman, Siamese sisters, and a few other grotesques of that type. And he discovers the target in a Soda City, an electric dam that provides Los Angeles and its war industry with the energy they need. He takes part as a gravel in the organization in the sabotage of a USS Alaska military ship when it is launched. And finally with some inventiveness, creativity and elbow grease he and the pianist's niece manage to get the whole lot cleaned up, most of them arrested and the first saboteur, a certain Fry, falls down from the torch of the Statue of Liberty. That one won't fry on the old electric sparking chair. But Hitchcock is not yet in his habit of having a personal cameo appearance in his own films, so don't look for him. It's well built and well performed, but it is only a propaganda film with an extra style.<br /><br />Dr Jacques COULARDEAU, University Paris Dauphine, University Paris 1 Pantheon Sorbonne & University Versailles Saint Quentin en Yvelines

significant enhancement of the detection efficiency with respect to a bulk
organic scintillator detector with the same thickness is observed.

The problem of private information "leakage" (inadvertently or by malicious
design) from the myriad large centralized searchable data repositories drives
the need for an analytical framework that quantifies unequivocally how safe
private data can be (privacy) while still providing useful benefit (utility) to
multiple legitimate information consumers. Rate distortion theory is shown to
be a natural choice to develop such a framework which includes the following:
modeling of data sources, developing application independent utility and
privacy metrics, quantifying utility-privacy tradeoffs irrespective of the type
of data sources or the methods of providing privacy, developing a
side-information model for dealing with questions of external knowledge, and
studying a successive disclosure problem for multiple query data sources.

Perhaps Mbalula should read his Amilcar Cabral notes, again...
"We are fighting so that insults may no longer rule our countries, martyred and scorned for centuries, so that our peoples may never more be exploited by imperialists not only by people with white skin, because we do not confuse exploitation or exploiters with the colour of men's skins; we do not want any exploitation in our countries, not even by black people".

Who were they kidding with this? There was just too much in this film that was hard to digest. Right from when Arjun (Ajay Devgan) unknowingly wishes death on his father to when he arrives in London with his uncle(played by Om Puri) only to abandon him minutes later. The only problem with that theory is that anybody who has ever passed through London Heathrow knows that such a fête would be impossible to pull off and especially not by an Indian. But the film problems do not end there, there's the issue of the two main leads (Salman Khan and Ajay Devgan) passing as rock-stars on the verge of achieving their dreams. I mean yeah we saw success come to Susan Boyle (a woman in the UK achieving her dreams after age 50) but that was a rare case. It was really hard for me to suspend my disbelief because I felt that the casting of Salman and Ajay was just ill-conceived. They would never cast Madhuri Dixit and Sridevi to play the same roles so why should we be forced to watch Ajay Devgan and Salman Khan (men well into their 40s) prance around desperately trying to hang on to their 20s? Let's not even talk about the most self-conscious actress on screen today, Asin. This is her second film (that I have seen) and she is just hopeless as an actress, so conscious of her looks that she only concerns herself with looking good and voguing for the camera rather than giving in a good acting performance. It's just hard to believe that she turned down all those other movie roles to star in this fluff and then be so fluffy as an actress, nothing to write home about at all. And to top all of that, the film just boringly dragged on. There's nothing special about it at all, trust me you will predict every clichéd thing that is going to happen in it.

Not true. Union workers are not getting any cost of living increases for the duration of this contract. Plus being forced to give up two days pay by taking furlough days. Plus employee share of medical coverage has increased. These things have effectively reduced the take home pay of state works. I would not categorize that as "won't touch you" if you are union.

The movie has only one flaw, unfortunately this flaw damages all credibility of the piece.<br /><br />It starts with the condemnation of the Israeli occupation of disputed territories. It fails to address the reason Israelis are there. Egypt, Syria, Iraq and Jordan attacked Israel. This is why Israel "occupys" their land, because those countries lost it in a war they started.<br /><br />The film also claims that Israel has defied the U N by not complying with Resolution 242. Problem is, 242 was rejected immediately upon it's inception by.....the palestinians, making it void.<br /><br />Many films are put together well, and can really show footage that changes minds, but remember, when watching anything, believe none of what you hear, and only half of what you see.<br /><br />All participants in this film are known critics of Israel, and some have made many antisemitic public comments, removing any possible credibility to their words.<br /><br />All participants are in dire need of a actual history lesson taught objectively, not by some palestinian sympathizer.

The number of binaries containing black holes or neutron stars depends
critically on the fraction of binaries that survive supernova explosions. We
searched for surviving star plus remnant binaries in a sample of 49 supernova
remnants (SNR) containing 23 previously identified compact remnants and three
high mass X-ray binaries (HMXB), finding no new interacting or non-interacting
binaries. The upper limits on any main sequence stellar companion are typically
<0.2Msun and are at worst <3Msun. This implies that f<0.1 of core collapse SNRs
contain a non-interacting binary, and f=0.083 (0.032<f<0.17) contain an
interacting binary at 90% confidence. We also find that the transverse
velocities of HMXBs are low, with a median of only 12~km/s for field HMXBs, so
surviving binaries will generally be found very close to the explosion center.
We compare the results to a "standard" StarTrack binary population synthesis
(BPS) model, finding reasonable agreement with the observations. In particular,
the BPS models predict that 5% of SNe should leave a star plus remnant binary.

We investigate the impact of bursts in star formation on the predictions of
one-zone chemical evolution models, adopting oxygen (O), iron (Fe), and
strontium (Sr), as representative $\alpha$, iron-peak, and s-process elements,
respectively. To this end, we develop the Versatile Integrator for Chemical
Evolution (VICE), a python package. Starbursts driven by a temporary boost of
gas accretion rate create loops in [O/Fe]-[Fe/H] evolutionary tracks and a peak
in the stellar [O/Fe] distribution at intermediate values. Bursts driven by a
temporary boost of star formation efficiency have a similar effect, and they
also produce a population of $\alpha$-deficient stars during the depressed star
formation phase that follows the burst. This $\alpha$-deficient population is
more prominent if the outflow rate is tied to a time-averaged star formation
rate (SFR) instead of the instantaneous SFR. Theoretical models of Sr
production predict a strong metallicity dependence of supernova and asymptotic
giant branch (AGB) star yields, though comparison to data suggests an
additional source that is nearly metallicity-independent. Evolution of [Sr/Fe]
and [Sr/O] during a starburst is complex because of the yield metallicity
dependence and the multiple timescales in play. Moderate amplitude (10-20\%)
sinusoidal oscillations in SFR produce loops in [O/Fe]-[Fe/H] tracks and
multiple peaks in [O/Fe] distributions, which could be one source of intrinsic
scatter in observed sequences. We investigate models that have a factor of ~2
enhancement of SFR at t = 12 Gyr, as suggest by some recent Milky Way
observations. A late episode of enhanced star formation could help explain the
existence of young stars with moderate $\alpha$-enhancements and the
surprisingly young median age found for solar metallicity stars in the solar
neighborhood, while also raising the possibility that this starburst has not
fully decayed.

We give explicit bounds on sums of $d(n)^2$ and $d_4(n)$, where $d(n)$ is the
number of divisors of $n$ and $d_4(n)$ is the number of ways of writing $n$ as
a product of four numbers. In doing so we make a slight improvement on the
upper bound for class numbers of quartic number fields.

The outflowing magnetized wind from a host star shapes planetary and
exoplanetary magnetospheres dictating the extent of its impact. We carry out
three-dimensional (3D) compressible magnetohydrodynamic (MHD) simulations of
the interactions between magnetized stellar winds and planetary magnetospheres
corresponding to a far-out star-planet system, with and without planetary
dipole obliquity. We identify the pathways that lead to the formation of a
dynamical steady-state magnetosphere and find that magnetic reconnection plays
a fundamental role in the process. The magnetic energy density is found to be
greater on the night-side than that on the day-side and the magnetotail is
comparatively more dynamic. Magnetotail reconnection events are seen to
associated with stellar wind plasma injection into the inner magnetosphere. We
further study magnetospheres with extreme tilt angles keeping in perspective
the examples of Uranus and Neptune. High dipole obliquities may also manifest
due to polarity excursions during planetary field reversals. We find that
global magnetospheric reconnection sites change for large planetary dipole
obliquity and more complex current sheet structures are generated. We discuss
the implications of these findings for injection of interplanetary species and
energetic particles into the inner magnetosphere, auroral activity and
magnetospheric radio emission. This study is relevant for exploring star planet
interactions in the solar and extra-solar systems.

We propose a flexible approach for computing the resolvent of the sum of
weakly monotone operators in real Hilbert spaces. This relies on splitting
methods where strong convergence is guaranteed. We also prove linear
convergence under Lipschitz continuity assumption. The approach is then applied
to computing the proximity operator of the sum of weakly convex functions, and
particularly to finding the best approximation to the intersection of convex
sets.

We quantify the correlation between earthquakes and use the same to
distinguish between relevant causally connected earthquakes. Our correlation
metric is a variation on the one introduced by Baiesi and Paczuski (2004). A
network of earthquakes is constructed, which is time ordered and with links
between the more correlated ones. Recurrences to earthquakes are identified
employing correlation thresholds to demarcate the most meaningful ones in each
cluster. Data pertaining to three different seismic regions, viz. California,
Japan and Himalayas, are comparatively analyzed using such a network model. The
distribution of recurrence lengths and recurrence times are two of the key
features analyzed to draw conclusions about the universal aspects of such a
network model. We find that the unimodal feature of recurrence length
distribution, which helps to associate typical rupture lengths with different
magnitude earthquakes, is robust across the different seismic regions. The
out-degree of the networks shows a hub structure rooted on the large magnitude
earthquakes. In-degree distribution is seen to be dependent on the density of
events in the neighborhood. Power laws, with two regimes having different
exponents, are obtained with recurrence time distribution. This is in agreement
with the Omori law for aftershocks and extends it to spatial recurrences. The
crossover to the second power law regime can be taken to be signalling the end
of aftershock regime in an objective fashion.

We use active microrheology to determine the frequency dependent moduli of a
linear viscoelastic fluid in terms of the polymer time constant ($\lambda$),
and the polymer ($\mu_p$) and solvent viscosity ($\mu_s$), respectively. We
measure these parameters from the response function of an optically trapped
Brownian probe in the fluid under an external perturbation, and at different
dilutions of the viscoelastic component in the fluid. This is an improvement
over bulk microrheology measurements in viscoelastic Stokes-Oldroyd B fluids
which determine the complex elastic modulus $G(\omega)$ of the fluid, but do
not, however, reveal the characteristics of the polymer chains and the
Newtonian solvent of the complex fluid individually. In a recent work [Paul
\textit{et al}., 2018 J. Phys. Condens. Matter \textbf{30} 345101], we
linearized the Stokes-Oldroyd B fluid model and thereby explicitly formulated
the frequency dependent moduli in terms of ($\mu_p$) and ($\mu_s$), which we
now extend to account for an external sinusoidal force applied to the probe
particle. We measure $\lambda$, $\mu_p$, and $\mu_s$ experimentally, and
compare with existing the $\lambda$ values in the literature for the same fluid
at some of the dilution levels, and obtain good agreement. Further, we use
these parameters to calculate the complex elastic modulus of the fluid again at
certain dilutions and verify successfully with existing data. This establishes
our method as an alternate approach in the active microrheology of complex
fluids which should reveal information about the composition of such fluids in
significantly greater detail and high signal to noise.

We consider how local and global decision policies interact in stopping time
problems such as quickest time change detection. Individual agents make myopic
local decisions via social learning, that is, each agent records a private
observation of a noisy underlying state process, selfishly optimizes its local
utility and then broadcasts its local decision. Given these local decisions,
how can a global decision maker achieve quickest time change detection when the
underlying state changes according to a phase-type distribution? The paper
presents four results. First, using Blackwell dominance of measures, it is
shown that the optimal cost incurred in social learning based quickest
detection is always larger than that of classical quickest detection. Second,
it is shown that in general the optimal decision policy for social learning
based quickest detection is characterized by multiple thresholds within the
space of Bayesian distributions. Third, using lattice programming and
stochastic dominance, sufficient conditions are given for the optimal decision
policy to consist of a single linear hyperplane, or, more generally, a
threshold curve. Estimation of the optimal linear approximation to this
threshold curve is formulated as a simulation-based stochastic optimization
problem. Finally, the paper shows that in multi-agent sensor management with
quickest detection, where each agent views the world according to its prior,
the optimal policy has a similar structure to social learning.

Too much work if you like being lazy!
Sometimes it’s 11pm and you just want to get in the car, go to Safeway and get your ice cream. It’s hard to do that when the car cover is a part of the picture. I found myself not driving my car for over a week because I didn’t want to remove the thing and potentially deal with a spider crawling out from Under it.. and onto me... and then having to put it back on. Who has time and energy for that? Nevertheless, it does the job. I don’t use the little lock strap that comes with it, but it kept my car clean and didn’t scratch it. It’s also too big for the bag it comes in, so I have to keep it in a ball in the back of my car which I do not enjoy. This is mainly a personal preference thing.

We provide an asymptotic expansion of the value function of a
multidimensional utility maximization problem from consumption with small
non-linear price impact. In our model cross-impacts between assets are allowed.
In the limit for small price impact, we determine the asymptotic expansion of
the value function around its frictionless version. The leading order
correction is characterized by a nonlinear second order PDE related to an
ergodic control problem and a linear parabolic PDE. We illustrate our result on
a multivariate geometric Brownian motion price model.

We have calculated surface energies and surface magnetic order of various
low-indexed surfaces of monoatomic Fe, Co, and Pt, and binary, ordered FePt,
CoPt, and MnPt using density functional theory. Our results for the binary
systems indicate that elemental, Pt-covered surfaces are preferred over Fe- and
Co-covered and mixed surfaces of the same orientation. The lowest energy
orientation for mixed surfaces is the highly coordinated (111) surface. We find
Pt-covered (111) surfaces, which can be realized in the L11 structure only, to
be lower in energy by about 400 meV/atom compared to the mixed L10 (111)
surface. We conclude that this low surface energy stabilizes the L11 structure
in small nanoparticles, which is suppressed in bulk alloys, but has been
recently synthesized as thin film for CoPt. From the interplay of surface and
bulk energies, equilibrium shapes of single-crystalline ordered nanoparticles
and crossover sizes between the different orderings can be estimated.

We present a study of the connection between star-forming galaxies, AGN host
galaxies, and normal early-type galaxies in the Sloan Digital Sky Survey
(SDSS). Using the SDSS DR5 and DR4plus data, we select our early-type galaxy
sample in the color versus color-gradient space, and we classify the spectral
types of the selected early-type galaxies into normal, star-forming, Seyfert,
and LINER classes, using several spectral line flux ratios. We investigate the
slope in the fundamental space for each class of early-type galaxies and find
that there are obvious differences in the slopes of the fundamental planes
(FPs) among the different classes of early-type galaxies, in the sense that the
slopes for Seyferts and star-forming galaxies are flatter than those for normal
galaxies and LINERs. This may be the first identification of the systematic
variation of the FP slope among the subclasses of early-type galaxies. The
difference in the FP slope might be caused by the difference in the degree of
nonhomology among different classes or by the difference of gas contents in
their merging progenitors. One possible scenario is that the AGN host galaxies
and star-forming galaxies are formed by gas-rich merging and that they may
evolve into normal early-type galaxies after finishing their star formation or
AGN activities.

The funniest movie from Britain I have ever seen, "The Supergrass" is a tale of sex, drugs, cream teas, and murder by the seaside. Dennis Carter (Adrian Edmonson), average moron, is out to impress his so-called girlfriend, Andrea (Dawn French), because she thinks he is too law-abiding. So, to get her to come along with him on a romantic getaway, he comes up with a scheme that perhaps will impress her and entice her to spend some time with him. Trouble is, Dennis' lie is that he's somehow gotten involved in an international drugs ring, and while telling her, a couple of policemen overhear his boasting and nick him. And so begins this witty movie, full of slick comedy and crude jokes. Dennis is banged up in the local nick, and, much to the arresting officers' delight, there seems to be no way out (Andrea's earlier attempts to explain it was all a lie were dismissed by a hilarious melody of "Stand by Your Man" by the two officers'). Then comes along Commander Robertson (Ronald Allen), Chief Intelligence, Scotland Yard. He makes a deal with Dennis, that if he helps him catch the drug smugglers, then he will be set free and allowed whatever he pleases. Dennis agrees, and is teamed up with Harvey Duncan (Peter Richardson), and Lesley Reynolds (Jennifer Saunders). The rest is an unforgettable rib-tickling experience, with Robbie Coltrane as Sergeant Troy adding humourous colour to the film. His walk along the dry-dock against "Frankie Goes To Hollywood's Two Tribes" is superb, and probably the best scene in motion picture history. The two officers' who nick Dennis are wonderfully played by Michael Elphick and Patrick Durkin, and Alexei Sayle as the motorcycle cop is a laugh! If you want something good to watch on a Saturday night, then I suggest you rent this. You won't forget it!

The COSY-11 collaboration measured the pp -> ppeta and pp -> ppeta' reactions
in order to perform comparative studies of the interactions within the
proton-proton-meson system. This thesis presents in detail the analysis of the
pp -> ppeta' reaction which was measured at the proton beam momentum of 3.260
GeV/c. The elaboration results in differential distributions of squared
invariant proton-proton (s_pp) and proton-eta' (s_peta') masses, as well as in
angular distributions and the total cross section at an excess energy of 16.4
MeV. The differential distributions s_pp and s_peta' are compared to
theoretical predictions and to the analogous spectra determined for the pp ->
ppeta reaction. The comparison of the results for the eta and eta' meson
production rather excludes the hypothesis that the enhancement observed in the
invariant mass distributions is due to the meson-proton interaction. Further,
the shapes of the distributions do not favour any of the postulated theoretical
models.

The Tooth Fairy is about the ghost of an old deformed witch that lures children to her house to get a prize for their loose tooth and then takes their lives. The first few minutes introduce you to the 1949 beginning of the legend of the tooth fairy and then switches to present day. The worn out horror plot is pretty much saved by the solid acting. They could have done without the Hammond brothers and a few other scenes, but overall the gore scenes were bloody but quick which had a minimizing effect. The eye candy is pretty good for both genders. Camera work is good. Dialog is fair but cheesy. I expected the film to be a bare bones, low budget, slasher with very few redeeming factors. I was surprised by the quality of the film.

The colors aren't very bright or different from each other.
For the price, it's ok. There's only 4 trains inside and some of the colors of the dots are so similar that you have to pay close attention. Other sets I've played with the colors are all bright and different. The rules aren't very thorough for Mexican train but luckily we already know how to play.

Gauge mediation of supersymmetry breakdown has many attractive features and
can be realized in phenomenologically interesting string-motivated models. We
point out that in models with the Polonyi-like field stabilized at a low
expectation value by quantum corrections, gravity seems to limit from above the
admixture of gravity mediation to the dominant gauge mediation channel.
However, we also point out that in a class of such models the low energy
metastable supersymmetry breaking vaccum appears to be cosmologically
disfavoured. These features should hold also in the case of typical stabilized
models with anomalous U(1) groups.

Medical image synthesis has gained a great focus recently, especially after
the introduction of Generative Adversarial Networks (GANs). GANs have been used
widely to provide anatomically-plausible and diverse samples for augmentation
and other applications, including segmentation and super resolution. In our
previous work, Deep Convolutional GANs were used to generate synthetic
mammogram lesions, masses mainly, that could enhance the classification
performance in imbalanced datasets. In this new work, a deeper investigation
was carried out to explore other aspects of the generated images evaluation,
i.e., realism, feature space distribution, and observers studies. t-Stochastic
Neighbor Embedding (t-SNE) was used to reduce the dimensionality of real and
fake images to enable 2D visualisations. Additionally, two expert radiologists
performed a realism-evaluation study. Visualisations showed that the generated
images have a similar feature distribution of the real ones, avoiding outliers.
Moreover, Receiver Operating Characteristic (ROC) curve showed that the
radiologists could not, in many cases, distinguish between synthetic and real
lesions, giving 48% and 61% accuracies in a balanced sample set.

I've read a lot of comments about this story. Most make a good example of community safety and dog owner laws. The one comment about "Real Alaskans Don't Shoot Dogs" is a hoot. And the part where the dog owner put up a "Dog Killer" sign with a memorial lawn decoration is bad-face and reflects immature attitudes with the owner and anyone who contributed to the memorial. Heated debates on both parties, but the neighborhood should of involved the "Accused Dog Killer" in the meeting. Looks to me that neighborhood is singling the family out and would rather have them isolated along with the children, who shouldn't need that kind of welcome, especially when they just moved into a new city and would like to have make new friends. They're all immature and bullies for trying to have a meeting to not let their kids play with Mellerstig's kids. GOOD PARENTING. Show your kids how to be snobs and now they will be making fun of the children because he shot the neighborhood dog, who everyone loved.

House of Dracula works from the same basic premise as House of Frankenstein from the year before; namely that Universal's three most famous monsters; Dracula, Frankenstein's Monster and The Wolf Man are appearing in the movie together. Naturally, the film is rather messy therefore, but the fact that all three monsters are there is usually enough to ensure that the film's sixty seven minutes don't become boring. It's obvious that the idea of making another monster mash came into the writer's head before an actual plot did, as the yarn we're given isn't exactly without holes. The plot sees Count Dracula arrive at Dr. Edelman's home asking for a cure for his vampirism. Then, what can only be described as a coincidence, sees Lawrence Talbot, a.k.a. The Wolf Man turn up asking for a cure for his affliction! It turns out that Dracula is on the prowl for Edelman's daughter, but Talbot really is serious. When it turns out that he can't be stopped from turning into a wolf, The Wolf Man throws himself into the sea...where he ends up finding Frankenstein's Monster.<br /><br />Overall, this film isn't as good as the earlier House of Frankenstein. The 1944 film put its plot together better than this entry in the series does, as the plot here doesn't give equal time to each Universal monster. Dracula's plot is the biggest at first, but soon fizzles out only to resurface at the end. The Wolf Man is the star of the show, but his story never really develops, and is essentially just another version of the plot he always finds himself in. Frankenstein's Monster is given the coldest hand, as he appears in the movie merely as an afterthought, and an obvious excuse to ensure that all three monsters appear in the movie. The story of the doctor who binds all three together is the most interesting, but this is a little disappointing as he isn't the reason why people will see this film. The acting is good enough, with John Carradine showing his sinister side and Lon Chaney Jr once again making sure that his character is bathed in tragedy. Glenn Strange is given nothing to do, and Onslow Stevens proves the real highlight as Dr Edelman. Overall, this film won't do much for anyone that isn't a fan of Universal horror; but as silly monster movies go, House of Dracula is worth seeing.

A preliminary overview of measurement-based quantum computation in the
setting of symmetry and topological phases of quantum matter is given. The
underlying mechanism for universal quantum computation by teleportation or
symmetry are analyzed, with the emphasis on the relation with tensor-network
states in the presence of various symmetries. Perspectives are also given for
the role of symmetry and phases of quantum matter in measurement-based quantum
computation and fault tolerance.

The mouse is tiny!
Overall it is a decent setup for the price. The keyboard feels good as do the buttons on the mouse and everything works well. The mouse however is VERY small, significantly smaller than my previous 2 button logitech. I have pretty small hands and it still feels tiny, I would definitely look for other options if you have big (or even normal sized) hands.

By God, it's been a long time since I saw this. Probably about 18 years ago?<br /><br />The movie tells us (kids) all about human blood and the circulatory system. Very professionally put together--Disney-style animation, plus human actors--it was directed by Frank Capra, for pete's sake!<br /><br />Kind of an overkill. I wonder if the very high production value is worth what amounts to a film-strip's worth of information on the human body? But boy will those kids watching it learn: even now I can clearly remember Dr. Baxter being challenged by Hemo himself to name what common material most resembles human blood, to which the Doctor immediately answers "sea water."

Man, do you not realise that it's a PRIVATE corporation that's being sold, and you are asking the GOVERNMENT to step in and meddle with the sale? And to use some arbitrary "national security" provision to do so?
Just as governments should get out of people's bedrooms, governments should get out of private business deals.

Amitabh and Jiah Khan, raised great expectations, by their press conferences, though it was quite easy for the critics, and the fans too, that after all, this much hyped, Ram Gopal Verma Factory product, is going to fall flat on it's face, in all the probabilities ! Why, because Jiah was so immature and childish, and Bacchan, mixed up guilty, and unsure . they themselves didn't know, what the hell they were talking about, to the press, keeping up with the tag line, that some love stories are not to be understood, or some such rubbish ! Why the title is Nishabd ? Ramu needs to refresh his knowledge of Sanskrit, as Vidhu Vinod needs to study Mahabharata, tagging in line, another glorious flop of the year, Eklavya ! Comparison with the Sweet hearts, and Lolit's is inevitable, as the so-called plot line is supposed to have inspired by them. but sadly, Ramu has hardly made any serious effort, to delve deeply into the psyche of the aging, and the young ones. is lolly pop sucking the ultimate indicator of the innocence ? and contrary to that streak of childishness, the leg show at the dining table, with a Vijay, that is Bacchan in that role, bursting into squeals of shameless laughter incessantly after wards ? this girl, is in fact at her seductive game, luring poor Vijay to think, she is in love with him. the legs,too are skinny enough, and that act of putting the water hose through the legs, is down right obscene. it's beyond any one's understanding, how can a girl , coming as a guest to some body's house, can be so brazen, brash, and over powering ? and why the hell that stupid wife, played by Revathi, remarkably well, though scripted poorly, and characterized unrealistically, encourages her own husband, to dance with a sexily saying young girl ? that part of Vijay, trying to gain some refreshers to his humdrum life is absolute bullshit. because, apparently it seems that he is happy as he is, with a well settled life, and a hobby to recreate. This reminds of Blame it on Rio, the older daddy, and his young love, superbly played by Michael Caine. Bacchan looks terrible in close ups, and over all, where as kevin spacey and Jeremy Irons looked debonair and handsome, which is why the young chicks some times get attracted to older men, for their charming persona, compared to the vulnerability of young boys of their age. only good thing about this movie is those green , sprawling land scapes , winding roads, and pleasant cinematography. no substance, or even any sparkling show of emotions, drama , or even intriguing, stormy sex like in Lolita, this shallow movie has no wonder, fallen flat on it's face, and had to be wound up from the screens during first weeks ! next time round, before mindlessly copying any such theme from Hollywood, Ramu should do his home work, and Bacchan should think twice ! you can not fool all the people at all the times, Mr. Bacchan!

We present two methods for proving confluence of left-linear term rewrite
systems. One is hot-decreasingness, combining the parallel/development
closedness theorems with rule labelling based on a terminating subsystem. The
other is critical-pair-closing system, allowing to boil down the confluence
problem to confluence of a special subsystem whose duplicating rules are
relatively terminating.

Differential cross sections of $t \overline{t}$ production have been measured
by the ATLAS experiment at the LHC. Monte Carlo calculations provide an overall
good modeling of all measured distributions, except for the transverse momentum
of the top quark, for which all the generators at the next-to-leading order
produce harder spectra. These measurements have been also included in the PDF
fits, contributing to a sensible reduction of the gluon PDF uncertainty at
large $x$.

Did the other reviewers watch the same movie I did? This was poorly written, poorly acted, and just overall boring. I made it well past the halfway point in the movie and then just gave up. I can't possibly imagine an ending that would have made the rest of the movie worthwhile. Don't waste your time with this dog. Seriously.

Humans make decisions and act alongside other humans to pursue both
short-term and long-term goals. As a result of ongoing progress in areas such
as computing science and automation, humans now also interact with non-human
agents of varying complexity as part of their day-to-day activities;
substantial work is being done to integrate increasingly intelligent machine
agents into human work and play. With increases in the cognitive, sensory, and
motor capacity of these agents, intelligent machinery for human assistance can
now reasonably be considered to engage in joint action with humans---i.e., two
or more agents adapting their behaviour and their understanding of each other
so as to progress in shared objectives or goals. The mechanisms, conditions,
and opportunities for skillful joint action in human-machine partnerships is of
great interest to multiple communities. Despite this, human-machine joint
action is as yet under-explored, especially in cases where a human and an
intelligent machine interact in a persistent way during the course of
real-time, daily-life experience. In this work, we contribute a virtual reality
environment wherein a human and an agent can adapt their predictions, their
actions, and their communication so as to pursue a simple foraging task. In a
case study with a single participant, we provide an example of human-agent
coordination and decision-making involving prediction learning on the part of
the human and the machine agent, and control learning on the part of the
machine agent wherein audio communication signals are used to cue its human
partner in service of acquiring shared reward. These comparisons suggest the
utility of studying human-machine coordination in a virtual reality
environment, and identify further research that will expand our understanding
of persistent human-machine joint action.

Quite the arena here for a xenophobia festival.

Immigrants bring wealth with them and/or create new wealth.
They commit crimes at a lower rate than the non-immigrant population, and they use less social services than the non-immigrant population.

An increasing number of experiments at the Belle, BNL, CERN, DA{\Phi}NE and
SLAC accelerators are confirming the violation of time reversal invariance (T).
The violation signifies a fundamental asymmetry between the past and future and
calls for a major shift in the way we think about time. Here we show that
processes which violate T symmetry induce destructive interference between
different paths that the universe can take through time. The interference
eliminates all paths except for two that represent continuously forwards and
continuously backwards time evolution. Evidence from the accelerator
experiments indicates which path the universe is effectively following. This
work may provide fresh insight into the long-standing problem of modeling the
dynamics of T violation processes. It suggests that T violation has previously
unknown, large-scale physical effects and that these effects underlie the
origin of the unidirectionality of time. It may have implications for the
Wheeler-DeWitt equation of canonical quantum gravity. Finally it provides a
view of the quantum nature of time itself.

Visual reasoning is a special visual question answering problem that is
multi-step and compositional by nature, and also requires intensive text-vision
interactions. We propose CMM: Cascaded Mutual Modulation as a novel end-to-end
visual reasoning model. CMM includes a multi-step comprehension process for
both question and image. In each step, we use a Feature-wise Linear Modulation
(FiLM) technique to enable textual/visual pipeline to mutually control each
other. Experiments show that CMM significantly outperforms most related models,
and reach state-of-the-arts on two visual reasoning benchmarks: CLEVR and NLVR,
collected from both synthetic and natural languages. Ablation studies confirm
that both our multistep framework and our visual-guided language modulation are
critical to the task. Our code is available at
https://github.com/FlamingHorizon/CMM-VR.

The efficiency of top-K item recommendation based on implicit feedback are
vital to recommender systems in real world, but it is very challenging due to
the lack of negative samples and the large number of candidate items. To
address the challenges, we firstly introduce an improved Graph Convolutional
Network~(GCN) model with high-order feature interaction considered. Then we
distill the ranking information derived from GCN into binarized collaborative
filtering, which makes use of binary representation to improve the efficiency
of online recommendation. However, binary codes are not only hard to be
optimized but also likely to incur the loss of information during the training
processing. Therefore, we propose a novel framework to convert the binary
constrained optimization problem into an equivalent continuous optimization
problem with a stochastic penalty. The binarized collaborative filtering model
is then easily optimized by many popular solvers like SGD and Adam. The
proposed algorithm is finally evaluated on three real-world datasets and shown
the superiority to the competing baselines.

Missing parts
I bought this as a gift for my husband. It was well packaged and nothing broke. I only opened it when I received it to Make sure it was whole. It is solid and nice looking but it is missing the round glass cork pictured in all the photos. I logged on to see if I could contact the seller but it did not give me an option. I'd be happy to change my star review if we can resolve the missing part. Overall it is a nice display set, we haven't used it yet, but it seems like it'll work as described, just missing the top cork.

An attempt at crossover to appeal to those who don't appreciate opera, exploiting the fame of one of the greatest opera singers of all time, it fails badly. All that is desirable in this movie is the opera, and one can best find a recording of Pavarotti doing what he does best. The plot revolves around a romance with a doctor who heals his throat which has suddenly become troublesome. <br /><br />Only because it came out so long ago is it largely forgotten. Like most opera stars, Pavarotti is a decent actor and has stage presence aside from his singing talent, and nothing that he does in this movie negates that opinion. His culpability lies in not rejecting the horrid script. Perhaps because great operas can have silly stories he tolerated this one.<br /><br />Who knows, except those involved? Do we need to know? <br /><br />The plot is weak and trite. This movie is like trudging through cold mud to pick off a few juicy tidbits (the opera music) hanging above the mud. We have other ways in which to appreciate the great Pavarotti, and this one isn't one of them. Just get one of his many superb opera or vocal-concert recordings and recognize the master tenor where he is most suited.<br /><br />It would be one of IMDb's 100 Worst Films if more people remembered it and gave it some votes; it would fit neatly in a list including several efforts of singers, actors, models, and athletes to exploit their popularity through film. Very often it all goes badly wrong due to incompetent acting or a horrible script. Pavarotti would have been a decent actor had he not shown such a superb voice. However effective he is as an actor (opera requires it), not even Jimmy Stewart could have rescued this turkey of a script.<br /><br />I give it a polite 3 of 10 because someone may have become a fan of Pavarotti's singing and of opera because of this movie.

Oxygen vacancies at the SnO2(110) and (101) surface and subsurface sites have
been studied in the framework of density functional theory by using both
all-electron Gaussian and pseudopotential plane-wave methods. The all-electron
calculations have been performed using the B3LYP exchange-correlation
functional with accurate estimations of energy gaps and density of states. We
show that bulk oxygen vacancies are responsible for the appearance of a fully
occupied flat energy level lying at about 1 eV above the top valence band, and
an empty level resonant with the conduction band. Surface oxygen vacancies
strongly modify the surface band structures with the appearance of intragap
states covering most of the forbidden energy window, or only a small part of
it, depending on the vacancy depth from the surface. Oxygen vacancies can
account for electron affinity variations with respect to the stoichiometric
surfaces as well. A significant support to the present results is found by
comparing them to the available experimental data.

We describe the design and operation of a system for xenon liquefaction in
which the condenser is separated from the liquid storage vessel. The condenser
is cooled by a pulse tube cryocooler, while the vessel is cooled only by the
liquid xenon itself. This arrangement facilitates liquid particle detector
research by allowing easy access to the upper and lower flanges of the vessel.
We find that an external xenon gas pump is useful for increasing the rate at
which cooling power is delivered to the vessel, and we present measurements of
the power and efficiency of the apparatus.

We present a variant of the quantum relational Hoare logic from (Unruh, POPL
2019) that allows us to use "expectations" in pre- and postconditions. That is,
when reasoning about pairs of programs, our logic allows us to quantitatively
reason about how much certain pre-/postconditions are satisfied that refer to
the relationship between the programs inputs/outputs.

We present an investigation of the relationships between the radio properties
of a giant radio galaxy MRC B0319-454 and the surrounding galaxy distribution
with the aim of examining the influence of intergalactic gas and gravity
associated with the large-scale structure on the evolution in the radio
morphology. Our new radio continuum observations of the radio source, with high
surface brightness sensitivity, images the asymmetries in the megaparsec-scale
radio structure in total intensity and polarization. We compare these with the
3-D galaxy distribution derived from galaxy redshift surveys. Galaxy density
gradients are observed along and perpendicular to the radio axis: the
large-scale structure is consistent with a model wherein the galaxies trace the
ambient intergalactic gas and the evolution of the radio structures are
ram-pressure limited by this associated gas. Additionally, we have modeled the
off-axis evolution of the south-west radio lobe as deflection of a buoyant jet
backflow by a transverse gravitational field: the model is plausible if
entrainment is small. The case study presented here is a demonstration that
giant radio galaxies may be useful probes of the warm-hot intergalactic medium
believed to be associated with moderately over dense galaxy distributions.

We propose a dimensional regularization scheme to deal with the divergences
caused by colliding supercurrents inserted at the interaction points, in the
light-cone gauge NSR superstring field theory. We formulate the theory in $d$
dimensions and define the amplitudes as analytic functions of $d$. With an
appropriately chosen three-string interaction term and large negative $d$, the
tree level amplitudes for the (NS,NS) closed strings can be recast into a BRST
invariant form, using the superconformal field theory proposed in
Ref.[arXiv:0911.3704]. We show that in the limit $d \to 10$ they coincide with
the results of the first quantized theory. Therefore we obtain the desired
results without adding any contact interaction terms to the action.

Works with a slim case, but the macro lens is non-functional
The macro lens works only about 10% of the time, which is a big disappointment (without a case on the phone... it just isn't a functioning lens). The rest, after a couple of months of trying, were very disappointing as well, even with a very slim case on my iPhone 7. A couple of them get black edges/corners effect quite often that can't be removed no matter how carefully you place the camera (even without the case). Mostly, they're just fuzzy, even when attached without a case. Really, really not worth the purchase.

We construct a consistency test of General Relativity (GR) on cosmological
scales. This test enables us to distinguish between the two alternatives to
explain the late-time accelerated expansion of the universe, that is, dark
energy models based on GR and modified gravity models without dark energy. We
derive the consistency relation in GR which is written only in terms of
observables - the Hubble parameter, the density perturbations, the peculiar
velocities and the lensing potential. The breakdown of this consistency
relation implies that the Newton constant which governs large-scale structure
is different from that in the background cosmology, which is a typical feature
in modified gravity models. We propose a method to perform this test by
reconstructing the weak lensing spectrum from measured density perturbations
and peculiar velocities. This reconstruction relies on Poisson's equation in GR
to convert the density perturbations to the lensing potential. Hence any
inconsistency between the reconstructed lensing spectrum and the measured
lensing spectrum indicates the failure of GR on cosmological scales. The
difficulties in performing this test using actual observations are discussed.

In this article, we consider a nabla fractional boundary value problem with
general boundary conditions. Brackins \& Peterson \cite{Br} gave an explicit
expression for the corresponding Green's function. Here, we show that this
Green's function is nonnegative and obtain an upper bound for its maximum
value. Since the expression for the Green's function is complicated, derivation
of its properties may not be straightforward. For this purpose, we use a few
properties of fractional nabla Taylor monomials. Using the Green's function, we
will then develop a Lyapunov-type inequality for the nabla fractional boundary
value problem.

Femtocells are assuming an increasingly important role in the coverage and
capacity of cellular networks. In contrast to existing cellular systems,
femtocells are end-user deployed and controlled, randomly located, and rely on
third party backhaul (e.g. DSL or cable modem). Femtocells can be configured to
be either open access or closed access. Open access allows an arbitrary nearby
cellular user to use the femtocell, whereas closed access restricts the use of
the femtocell to users explicitly approved by the owner. Seemingly, the network
operator would prefer an open access deployment since this provides an
inexpensive way to expand their network capabilities, whereas the femtocell
owner would prefer closed access, in order to keep the femtocell's capacity and
backhaul to himself. We show mathematically and through simulations that the
reality is more complicated for both parties, and that the best approach
depends heavily on whether the multiple access scheme is orthogonal (TDMA or
OFDMA, per subband) or non-orthogonal (CDMA). In a TDMA/OFDMA network,
closed-access is typically preferable at high user densities, whereas in CDMA,
open access can provide gains of more than 200% for the home user by reducing
the near-far problem experienced by the femtocell. The results of this paper
suggest that the interests of the femtocell owner and the network operator are
more compatible than typically believed, and that CDMA femtocells should be
configured for open access whereas OFDMA or TDMA femtocells should adapt to the
cellular user density.

We consider groups of orientation-preserving real analytic diffeomorphisms of
the circle which have a finite image under the rotation number function. We
show that if such a group is nondiscrete with respect to the $C^1$-topology
then it has a finite orbit. As a corollary, we show that if such a group has no
finite orbit then each of its subgroups contains either a cyclic group of
finite index or a nonabelian free subgroup.

The first linear code supporting a $4$-design was the $[11, 6, 5]$ ternary
Golay code discovered in 1949 by Golay. In the past 71 years, sporadic linear
codes holding $4$-designs or $5$-designs were discovered and many infinite
families of linear codes supporting $3$-designs were constructed. However, the
question as to whether there is an infinite family of linear codes holding an
infinite family of $t$-designs for $t\geq 4$ remains open for 71 years. This
paper settles this long-standing problem by presenting an infinite family of
BCH codes of length $2^{2m+1}+1$ over $\mathrm{GF}(2^{2m+1})$ holding an
infinite family of $4$-$(2^{2m+1}+1, 6, 2^{2m}-4)$ designs. Moreover, an
infinite family of linear codes holding the spherical design $S(3, 5, 4^m+1)$
is presented.

The brain perfusion ROI detection being a preliminary step, designed to
exclude non-brain tissues from analyzed DSC perfusion MR images. Its accuracy
is considered as the key factor for delivering correct results of perfusion
data analysis. Despite the large variety of algorithms developed on brain
tissues segmentation, there is no one that works reliably and robustly on
2T-waited MR images of a human head with abnormal brain anatomy. Therefore,
thresholding method is still the state-of-the-art technique that is widely used
as a way of managing pixels involved in brain perfusion ROI. This paper
presents the analysis of effectiveness of thresholding techniques in brain
perfusion ROI detection on 2T-waited MR images of a human head with abnormal
brain anatomy. Four threshold-based algorithms implementation are considered:
according to Otsu method as global thresholding, according to Niblack method as
local thresholding, thresholding in approximate anatomical brain location, and
brute force thresholding. The analysis is done using comparison of qualitative
maps produced from thresholded images and from the reference ones. Pearson
correlation analysis showed strong positive (r was ranged from 0.7123 to
0.8518, p<0.01) and weak positive (r<0.35, p<0.01) relationship in case of
conducted experiments with CBF, CBV, MTT and Tmax maps, respectively. Linear
regression analysis showed at level of 95% confidence interval that maps
produced from thresholded images were subject to scale and offset errors in all
conducted experiments. The experimental results showed that widely used
thresholding methods are an ineffective way of managing pixels involved in
brain perfusion ROI. Thresholding as brain segmentation tool can lead to poor
placement of perfusion ROI and, as a result, produced maps will be subject to
artifacts and can cause falsely high or falsely low perfusion parameters
assessment.

To identify the main mechanisms underlying complex opinion formation
processes in social systems, researchers have long been exploring simple
mechanistic mathematical models. Most existing opinion dynamics models are
built on a common micro-foundation, i.e., the weighted-averaging opinion
update. However, we argue that this universally-adopted mechanism features a
non-negligible unrealistic feature, which brings unnecessary difficulties in
seeking a proper balance between model complexity and predictive power. In this
paper, we propose the weighted-median mechanism as a new micro-foundation of
opinion dynamics, which, with minimal assumptions, fundamentally resolves the
inherent unrealistic feature of the weighted-averaging mechanism. Derived from
the cognitive dissonance theory in psychology, the weighted-median mechanism is
supported by online experiment data and broadens the applicability of opinion
dynamics models to multiple-choice issues with ordered discrete options.
Moreover, the weighted-median mechanism, despite being the simplest in form,
captures various non-trivial real-world features of opinion evolution, while
some widely-studied averaging-based models fail to.

Nor are there any "good guys" in this, gray---at least, not on the national stage. It's interesting that Obama didn't immediately act to scale back the largely unchecked executive powers built up by his predecessors, but he didn't. The War on an emotion continues, and the casualties include American privacy, many of our freedoms, and the right to confront one's accusers, to name just a few.
In that light people like Assange are providing a public service, part of which was in revealing that, under Clinton, the State Department used its diplomats as spies and intelligence gatherers---As if they weren't compromised already!
If what Assange reveals somehow throws the election to the circus freaks, well, that's the price you pay for deceiving the American people.

Comfortable shirt but not well tailored
This is an inexpensive alternative to the name brands. I like the color of both of these shirts and the fabric, and I'm sure it would be great for someone who's got tighter abs, but for a large, it fits a little tight around the middle and doesn't hide my tummy the way I like. If it were a bit baggier, I'd be happier! I wear it when I'm exercising or hanging around the house, but I wouldn't wear it out.

We report a new approach to integrating high-\k{appa} dielectrics in both
bottom- and top-gated MoS2 field-effect transistors (FETs) through thermal
oxidation and mechanical assembly of layered twodimensional (2D) TaS2. Combined
X-ray photoelectron spectroscopy (XPS), optical microscopy, atomic force
microscopy (AFM), and capacitance-voltage (C-V) measurements confirm that
multilayer TaS2 flakes can be uniformly transformed to Ta2O5 with a high
dielectric constant of ~ 15.5 via thermal oxidation, while preserving the
geometry and ultra-smooth surfaces of 2D TMDs. Top-gated MoS2 FETs fabricated
using the thermally oxidized Ta2O5 as gate dielectric demonstrate a high
current on/off ratio approaching 106, a subthreshold swing (SS) down to 61
mV/dec, and a field-effect mobility exceeding 60 cm2V-1 s-1 at room
temperature, indicating high dielectric quality and low interface trap density.

Again, you are proving my point, ie, that the SCC bowed to social media pressure.
It should not matter what you or I think should be the correct number of intervenors; what matters is the judgement of a SCC justice. That is why they are there.. to make these decisions for us.
The SC justices are supposed to be the pre eminent of Canadian jurists, so allow them to do their job independently, or just scrap them altogether.

The Mathematica toolkit AMBRE derives Mellin-Barnes (MB) representations for
Feynman integrals in d=4-2eps dimensions. It may be applied for tadpoles as
well as for multi-leg multi-loop scalar and tensor integrals. AMBRE uses a
loop-by-loop approach and aims at lowest dimensions of the final MB
representations. The present version of AMBRE works fine for planar Feynman
diagrams. The output may be further processed by the package MB for the
determination of its singularity structure in eps. The AMBRE package contains
various sample applications for Feynman integrals with up to six external
particles and up to four loops.

Tournament solutions are frequently used to select winners from a set of
alternatives based on pairwise comparisons between alternatives. Prior work has
shown that several common tournament solutions tend to select large winner sets
and therefore have low discriminative power. In this paper, we propose a
general framework for refining tournament solutions. In order to distinguish
between winning alternatives, and also between non-winning ones, we introduce
the notion of margin of victory (MoV) for tournament solutions. MoV is a
robustness measure for individual alternatives: For winners, the MoV captures
the distance from dropping out of the winner set, and for non-winners, the
distance from entering the set. In each case, distance is measured in terms of
which pairwise comparisons would have to be reversed in order to achieve the
desired outcome. For common tournament solutions, including the top cycle, the
uncovered set, and the Banks set, we determine the complexity of computing the
MoV and provide worst-case bounds on the MoV for both winners and non-winners.
Our results can also be viewed from the perspective of bribery and
manipulation.

Keeps You Turning the Page
I found Vow of Retribution overall a really good book. At times it was a little more graphic than I would have liked but having said that it also made the storyline much more real to life. How someone can endure that abuse and come out the other side is amazing. I would certainly recommend this book to others.

Driving volatility captures the extent of speed variations when a vehicle is
being driven. Extreme longitudinal variations signify hard acceleration or
braking. Warnings and alerts given to drivers can reduce such volatility
potentially improving safety, energy use, and emissions. This study develops a
fundamental understanding of instantaneous driving decisions, needed for hazard
anticipation and notification systems, and distinguishes normal from anomalous
driving. In this study, driving task is divided into distinct yet unobserved
regimes. The research issue is to characterize and quantify these regimes in
typical driving cycles and the associated volatility of each regime, explore
when the regimes change and the key correlates associated with each regime.
Using Basic Safety Message (BSM) data from the Safety Pilot Model Deployment in
Ann Arbor, Michigan, two- and three-regime Dynamic Markov switching models are
estimated for several trips undertaken on various roadway types. While
thousands of instrumented vehicles with V2V and V2I communication systems are
being tested, nearly 1.4 million records of BSMs, from 184 trips undertaken by
71 instrumented vehicles are analyzed in this study. Then even more detailed
analysis of 43 randomly chosen trips (N = 714,340 BSM records) that were
undertaken on various roadway types is conducted. The results indicate that
acceleration and deceleration are two distinct regimes, and as compared to
acceleration, drivers decelerate at higher rates, and braking is significantly
more volatile than acceleration. Different correlations of the two regimes with
instantaneous driving contexts are explored. With a more generic three-regime
model specification, the results reveal high-rate acceleration, high-rate
deceleration, and cruise/constant as the three distinct regimes that
characterize a typical driving cycle. (Continued)

Voice communication over internet not be possible without a reliable data
network, this was first available when distributed network topologies were used
in conjunction with data packets. Early network used single centre node network
in which a single workstation (Server) is responsible for the communication.
This posed problems as if there was a fault with the centre node, (workstation)
nothing would work. This problem was solved by the distributed system in which
reliability increases by spreading the load between many nodes. The idea of
packet switching & distributed network were combined, this combination were
increased reliability, speed & responsible for voice communication over
internet, Voice-over-IP (VoIP)These data packets travel through a
packet-switched network such as the Internet and arrive at their destination
where they are decompressed using a compatible Codec (audio coder/decoder) and
converted back to analogue audio. This paper deals with the Simulink
architecture for VoIP network.

A popular approach for predicting the future of dynamical systems involves
mapping them into a lower-dimensional "latent space" where prediction is
easier. We show that the information-theoretically optimal approach uses
different mappings for present and future, in contrast to state-of-the-art
machine-learning approaches where both mappings are the same. We illustrate
this dichotomy by predicting the time-evolution of coupled harmonic oscillators
with dissipation and thermal noise, showing how the optimal 2-mapping method
significantly outperforms principal component analysis and all other approaches
that use a single latent representation, and discuss the intuitive reason why
two representations are better than one. We conjecture that a single latent
representation is optimal only for time-reversible processes, not for e.g.
text, speech, music or out-of-equilibrium physical systems.

The nature of dark matter is one of the outstanding questions of
astrophysics. The internal motions of member stars reveal that the lowest
luminosity galaxies in the Local Group are the most dark-matter dominated. New
large datasets allow one to go further, and determine systematic properties of
their dark matter haloes. We summarise recent results, emphasising the critical
role of the dwarf spheroidal galaxies in understanding both dark matter and
baryonic processes that shape galaxy evolution.
