The NA48/2 collaboration has shown clear experimental evidence for a cusp in
the data for K -> pi pi^0 pi^0. This effect can be used to extract information
on the pi-pi scattering lengths. We address this issue using a two-loop
dispersive construction of pi pi -> pi pi and K -> pi pi pi amplitudes in the
presence of isospin breaking.

Demosaicking and denoising are the first steps of any camera image processing
pipeline and are key for obtaining high quality RGB images. A promising current
research trend aims at solving these two problems jointly using convolutional
neural networks. Due to the unavailability of ground truth data these networks
cannot be currently trained using real RAW images. Instead, they resort to
simulated data. In this paper we present a method to learn demosaicking
directly from mosaicked images, without requiring ground truth RGB data. We
apply this to learn joint demosaicking and denoising only from RAW images, thus
enabling the use of real data. In addition we show that for this application
fine-tuning a network to a specific burst improves the quality of restoration
for both demosaicking and denoising.

We establish the existence of optimal scheduling strategies for time-bounded
reachability in continuous-time Markov decision processes, and of co-optimal
strategies for continuous-time Markov games. Furthermore, we show that optimal
control does not only exist, but has a surprisingly simple structure: The
optimal schedulers from our proofs are deterministic and timed-positional, and
the bounded time can be divided into a finite number of intervals, in which the
optimal strategies are positional. That is, we demonstrate the existence of
finite optimal control. Finally, we show that these pleasant properties of
Markov decision processes extend to the more general class of continuous-time
Markov games, and that both early and late schedulers show this behaviour.

We tend to think somewhat dismissively of cultures that ascribe absolute truth in all matters to supreme leaders, and of the zealots who believe every word, not matter how absurd.
And we think even less of people who would trade the truth for grub.
So you can come to your own conclusion about what we think of you. ;-)

We present analysis of the three-dimensional shape of intracluster gas in
clusters formed in cosmological simulations of the Lambda-CDM cosmology and
compare it to the shape of dark matter distribution and the shape of the
overall isopotential surfaces. We find that in simulations with radiative
cooling, star formation and stellar feedback (CSF), intracluster gas outside
the cluster core is more spherical compared to non-radiative (NR) simulations,
while in the core the gas in the CSF runs is more triaxial and has a distinctly
oblate shape. The latter reflects the ongoing cooling of gas, which settles
into a thick oblate ellipsoid as it loses thermal energy. The shape of the gas
in the inner regions of clusters can therefore be a useful diagnostic of gas
cooling. We find that gas traces the shape of the underlying potential rather
well outside the core, as expected in hydrostatic equilibrium. At smaller
radii, however, the gas and potential shapes differ significantly. In the CSF
runs, the difference reflects the fact that gas is partly rotationally
supported. Interestingly, we find that in NR simulations the difference between
gas and potential shape at small radii is due to random gas motions, which make
the gas distribution more spherical than the equipotential surfaces. Finally,
we use mock Chandra X-ray maps to show that the differences in shapes observed
in three-dimensional distribution of gas are discernible in the ellipticity of
X-ray isophotes. Contrasting the ellipticities measured in simulated clusters
against observations can therefore constrain the amount of cooling of the
intracluster medium and the presence of random gas motions in cluster cores.

We shall investigate the possibility of formulation of varying speed of light
(VSL) in the framework of Palatini non-linear Ricci scalar and Ricci squared
theories. Different speeds of light including the causal structure constant,
electromagnetic, and gravitational wave speeds are discussed. We shall see that
two local frames are distinguishable and discuss about the velocity of light in
these two frames. We shall investigate which one of these local frames is
inertial.

We briefly discuss recent research on the spin-averaged parton densities of
the proton, focusing on some aspects relevant to hard processes at the LHC.
Specifically, after recalling the basic framework and the need for higher-order
calculations, we address the evolution equations governing the scale dependence
of the parton distributions and their solution, schemes for initial conditions
and the inclusion of heavy quarks, recent progress on fits to data, and future
high-precision constraints from LHC measurements.

Nanometer-sized particular structures are generated on the surfaces of FeSe
epitaxial films directly after exposure to air; this phenomenon was studied in
the current work because these structures are an obstacle to field-induced
superconductivity in electric double-layer transistors using FeSe channel
layers. Chemical analyses using field-effect scanning Auger electron
spectroscopy revealed no clear difference in the chemical composition between
the particular structures and the other flat surface region. This observation
limits the possible origins of the particulate formation to light elements in
air such as O, C, H, and N.

Within the context of the twisted Poincar\'e algebra, there exists no
noncommutative analogue of the Minkowski space interpreted as the homogeneous
space of the Poincar\'e group quotiented by the Lorentz group. The usual
definition of commutative classical fields as sections of associated vector
bundles on the homogeneous space does not generalise to the noncommutative
setting, and the twisted Poincar\'e algebra does not act on noncommutative
fields in a canonical way. We make a tentative proposal for the definition of
noncommutative classical fields of any spin over the Moyal space, which has the
desired representation theoretical properties. We also suggest a way to search
for noncommutative Minkowski spaces suitable for studying noncommutative field
theory with deformed Poincar\'e symmetries.

Recent work by Sromovsky et al. (2017, Icarus 291, 232-244) suggested that
all red colour in Jupiter's atmosphere could be explained by a single
colour-carrying compound, a so-called 'universal chromophore'. We tested this
hypothesis on ground-based spectroscopic observations in the visible and
near-infrared (480-930 nm) from the VLT/MUSE instrument between 2014 and 2018,
retrieving a chromophore absorption spectrum directly from the North Equatorial
Belt, and applying it to model spatial variations in colour, tropospheric cloud
and haze structure on Jupiter. We found that we could model both the belts and
the Great Red Spot of Jupiter using the same chromophore compound, but that
this chromophore must exhibit a steeper blue-absorption gradient than the
proposed chromophore of Carlson et al. (2016, Icarus 274, 106-115). We
retrieved this chromophore to be located no deeper than 0.2+/-0.1 bars in the
Great Red Spot and 0.7+/-0.1 bars elsewhere on Jupiter. However, we also
identified some spectral variability between 510 nm and 540 nm that could not
be accounted for by a universal chromophore. In addition, we retrieved a thick,
global cloud layer at 1.4+/-0.3 bars that was relatively spatially invariant in
altitude across Jupiter. We found that this cloud layer was best characterised
by a real refractive index close to that of ammonia ice in the belts and the
Great Red Spot, and poorly characterised by a real refractive index of 1.6 or
greater. This may be the result of ammonia cloud at higher altitude obscuring a
deeper cloud layer of unknown composition.

This was just awful
Drill bits failed after a 1/2 hole in concrete. I saved the bit which basically bent after a couple of seconds of drilling to show to my friends. I've never seen such junk..On the positive side, the drill bit could have broken and gotten stuck in the hole but instead, it just bent and I was able to pull it out. The anchors are ok.

Works as described, but not recommended for high-risk scenarios
If you are looking to shoot a selfie off the top of your car, or something relatively flat, this works like a charm, and is light enough to fit into your backpack. However, if you are looking to use it to stick you phone to the side of a fence railing, overlooking a cliff, buy a better quality one. This is not strong enough for you to have peace of mind. A strong gust of wind might dislodge it and you will lose your phone!

The ocean wave distribution in a specific region of space and time is
described by its sea state. Knowledge about the sea states a ship encounters on
a journey can be used to assess various parameters of risk and wear associated
with the journey.
Two important characteristics of the sea state are the significant wave
height and mean wave period. We propose a joint spatial model of these two
quantities on the north Atlantic ocean. The model describes the distribution of
the logarithm of the two quantities as a bivariate Gaussian random field. This
random field is modeled as a solution to a system of coupled stochastic partial
differential equations. The bivariate random field can model a wide variety of
non-stationary anisotropy and allows for arbitrary, and different,
differentiability for the two marginal fields.
The parameters of the model are estimated on data of the north Atlantic using
a stepwise maximum likelihood method. The fitted model is used to derive the
distribution of accumulated fatigue damage for a ship sailing a transatlantic
route. Also, a method for estimating the risk of capsizing due to broaching-to,
based on the joint distribution of the two sea state characteristics, is
investigated. The risks are calculated for a transatlantic route between
America and Europe using both data and the fitted model.
The results show that the model compares well with observed data. Also, it
shows that the bivariate model is needed and cannot simply be approximated by a
model of significant wave height alone.

The Curie-Weiss Potts model is a mean field version of the well-known Potts
model. In this model, the critical line $\beta = \beta_c (h)$ is explicitly
known and corresponds to a first order transition when $q > 2$. In the present
paper we describe the fluctuations of the density vector in the whole domain
$\beta \geqslant 0$ and $h \geqslant 0$, including the conditional fluctuations
on the critical line and the non-Gaussian fluctuations at the extremity of the
critical line. The probabilities of each of the two thermodynamically stable
states on the critical line are also computed. Similar results are inferred for
the Random-Cluster model on the complete graph.

We study a new approach to determine the asymptotic behaviour of quantum
many-particle systems near coalescence points of particles which interact via
singular Coulomb potentials. This problem is of fundamental interest in
electronic structure theory in order to establish accurate and efficient models
for numerical simulations. Within our approach, coalescence points of particles
are treated as embedded geometric singularities in the configuration space of
electrons. Based on a general singular pseudo-differential calculus, we provide
a recursive scheme for the calculation of the parametrix and corresponding
Green operator of a nonrelativistic Hamiltonian. In our singular calculus, the
Green operator encodes all the asymptotic information of the eigenfunctions.
Explicit calculations and an asymptotic representation for the Green operator
of the hydrogen atom and isoelectronic ions are presented.

It wasn't a problem to spend federal dollars in New Orleans after Katrina. In fact, President Bush was lambasted by the press and liberals for not doing more and sooner. The problem appears to be a matter of scale; New Orleans was big, the Matanuska River inhabitants are politically small. It is not a problem to pour welfare money into native villages that have no economic foundation, but it's a problem to help the few hapless homeowners along the Matanuska River. Indeed, the Matanuska River homeowners could have made a better decision about where to erect a home, but to some extent that includes all of us. Let's see what happens the next time the ground shakes in Anchorage. How many of the sanctimonious commentators will eschew federal money to rebuild their homes? If federal relief money is good for some because of politics then it is good for all. It's a slippery slope!

This film was bad. I believe Elton (or is it Mike) Wong starred in it. Anyway it was the Wong that didn't have that goofy grin and looks meaner. He plays a man who is hit over the head and suffers brain damage. He recovers and gets revenge. Gordon Liu is the only one worth seeing in this film, but he doesn't get to do much. But what little he does seems to make the<br /><br />others pale in comparison. Also, the film has some cheesy rubber hawk that the Wong guy controls. This film is not worth renting or buying.

Student: Buildings and vehicles are well heated and people wear a lot of warm clothing when they go outdoor in the cold part of the winter. But there is no escaping the fact that the weather can be bitter at times, particularly if you are not used to the cold. It is a big expanse of country and the weather can be harsh. A couple of days ago I was walking around in a jacket. Today I have my down-filled parka and other extra garments. I will stay in most of today until the bitter wind abates. It is very comfie indoors. I hope this is helpful.
Saskatchewan is a beautiful province (like the other ones).

By withdrawing our resolution, I am nonetheless convinced that our Parliament would have done better in devoting its voice to the Nice European Council, a specific resolution and separate issues so important and so difficult to the Intergovernmental Conference, rather than to deal with them in the context of a single resolution including also all the other items on the agenda of the Council.

Deep, narrow-band \Ha\ and 6584 \AA\ [\Nii ] CCD images of the peculiar,
infrared excess B[e] star MWC~922 reveal a collimated, bipolar jet orthogonal
to the previously detected extended nebula. The jet consists of a pair of
$\sim$0.15 pc segments on either side of MWC~922 separated by gaps. The most
distant jet segments disappear $\sim$0.6 pc from the star. The northwest beam
points to a faint emission-line feature 1.65 pc from MWC~922 that may be a
terminal bow shock where the jet rams the ambient medium. The narrow
opening-angle of the jet combined with an estimated internal sound speed of
$\sim$10 \kms\ implies a jet speed $\sim$500 \kms . The previously detected
nebula extends up to 0.6~pc to the southwest of MWC~922 at right angles to the
jet and appears to be an extension of the compact, edge-on disk surrounding the
star. It points toward the HII region Messier 16 located $\sim$1\degr\
($\sim$30 pc in projection) to the southwest. This nebula and jet appear to be
externally ionized by the ambient Lyman continuum radiation field and have
electron densities of n$_e \sim$ 50 to 100 cm$^{-3}$. The southwest nebula and
jet have similar surface brightness in \Ha\ and [\Nii ]. Faint 70 $\mu$m
emission traces the southwest ejecta that likely originates from $\sim$50 K
dust embedded in the photo-ionized plasma which may shadow the dimmer ejecta
northeast of MWC~922. MWC~922 may be a massive member of the Serpens OB1 or OB2
associations surrounding Messier 16 and Sh2-54.

Learning semantic segmentation models under image-level supervision is far
more challenging than under fully supervised setting. Without knowing the exact
pixel-label correspondence, most weakly-supervised methods rely on external
models to infer pseudo pixel-level labels for training semantic segmentation
models. In this paper, we aim to develop a single neural network without
resorting to any external models. We propose a novel self-guided strategy to
fully utilize features learned across multiple levels to progressively generate
the dense pseudo labels. First, we use high-level features as class-specific
localization maps to roughly locate the classes. Next, we propose an
affinity-guided method to encourage each localization map to be consistent with
their intermediate level features. Third, we adopt the training image itself as
guidance and propose a self-guided refinement to further transfer the image's
inherent structure into the maps. Finally, we derive pseudo pixel-level labels
from these localization maps and use the pseudo labels as ground truth to train
the semantic segmentation model. Our proposed self-guided strategy is a unified
framework, which is built on a single network and alternatively updates the
feature representation and refines localization maps during the training
procedure. Experimental results on PASCAL VOC 2012 segmentation benchmark
demonstrate that our method outperforms other weakly-supervised methods under
the same setting.

The observed light curves and other properties of the two extragalactic fast
x-ray transients, CDF-S XT1 and CDF-S XT2, which were discovered recently in
archival data of the Chandra Deep Field-South (CDF-S) observations, indicate
that they belong to two different populations of X-ray transients. XT1 seems to
be an x-ray flash (XRF), i.e., a narrowly beamed long duration gamma ray burst
viewed from far off-axis while XT2 seems to be a nebular emission powered by a
newly born millisecond pulsar in a neutron stars binary merger.

Justin lied to get to office and has broken alllll his key campaign pledges.
Perhaps he should apologize to Canadians for deliberately misleading them !!!
Yes who could forger :

Truly how foolish does this PM think we are ??
Words have consequences and he is going to need more than selfies and life size cut outs in 2019.

We have fit the far-ultraviolet (FUV) to sub-millimeter (850 micron) spectral
energy distributions (SEDs) of the 61 galaxies from the "Key Insights on Nearby
Galaxies: A Far-Infrared Survey with Herschel" (KINGFISH). The fitting has been
performed using three models: the Code for Investigating GALaxy Evolution
(CIGALE), the GRAphite-SILicate approach (GRASIL), and the Multi-wavelength
Analysis of Galaxy PHYSical properties (MAGPHYS). We have analyzed the results
of the three codes in terms of the SED shapes, and by comparing the derived
quantities with simple "recipes" for stellar mass (Mstar), star-formation rate
(SFR), dust mass (Mdust), and monochromatic luminosities. Although the
algorithms rely on different assumptions for star-formation history, dust
attenuation and dust reprocessing, they all well approximate the observed SEDs
and are in generally good agreement for the associated quantities. However, the
three codes show very different behavior in the mid-infrared regime, in
particular between 25 and 70 micron where there are no observational
constraints for the KINGFISH sample. We find that different algorithms give
discordant SFR estimates for galaxies with low specific SFR, and that the
standard "recipes" for calculating FUV absorption overestimate the extinction
compared to the SED-fitting results. Results also suggest that assuming a
"standard" constant stellar mass-to-light ratio overestimates Mstar relative to
the SED fitting, and we provide new SED-based formulations for estimating Mstar
from WISE W1 (3.4 micron) luminosities and colors. From a Principal Component
Analysis of Mstar, SFR, Mdust, and O/H, we reproduce previous scaling relations
among Mstar, SFR, and O/H, and find that Mdust can be predicted to within
roughly 0.3 dex using only Mstar and SFR.

A bit of damage, here and there.
The game came in two days, as promised, however there were marks on a few of the game pieces that take away from the beauty of this game. A few of the player boards, for example have crushed or peeling corners, which will no doubt result in further damage with use. The back of a couple of the player boards are also scratched. I was not thrilled upon discovering these flaws when I first opened the box.

Not great
This is one of those books I got for free that was worth every penny. I kept waiting for the story to start. I didn't like this book very much. I felt the characters were one dimensional, the plot was obvious and there was no life or character development I'd skip this.

It fits, but pretty bulky
The ruger security 9 with light & laser fits in the holster ok... only thing make sure you know this is not conceal & carry holster, it's pretty bulky, and like it states on diagram, made only to fit outside pants, not inside... I changed the clip and strap where I made it too fit inside pants, but it's awkward, and hard to get in and out of holster... when wearing it outside of pants on belt it's pretty bulky and heavy when you have the gun, laser, and extra magazine.

Ollie: as a transplanted Torontonian some time ago, I can identify with your concern, however the Big Smoke and the GTA, good and bad, despite all the ongoing nonsense, (including sports teams), is actually a great place. I share your angst about many of our dysfunctional institutions however, it still remains the Greatest City in our wonderful country. The Buds, nor the Globe and not even The Star constitute the city's magnificent status.

This article is devoted to the extension of the theory of rough paths in the
context of Volterra equations with possibly singular kernels. We begin to
describe a class of two parameter functions defined on the simplex called
Volterra paths. These paths are used to construct a so-called
Volterra-signature, analogously to the signature used in Lyon's theory of rough
paths. We provide a detailed algebraic and analytic description of this object.
Interestingly, the Volterra signature does not have a multiplicative property
similar to the classical signature, and we introduce an integral product
behaving like a convolution extending the classical tensor product. We show
that this convolution product is well defined for a large class of Volterra
paths, and we provide an analogue of the extension theorem from the theory of
rough paths (which guarantees in particular the existence of a Volterra
signature). Moreover the concept of convolution product is essential in the
construction of Volterra controlled paths, which is the natural class of
processes to be integrated with respect to the driving noise in our situation.
This leads to a rough integral given as a functional of the Volterra signature
and the Volterra controlled paths, combined through the convolution product.
The rough integral is then used in the construction of solutions to Volterra
equations driven by H\"older noises with singular kernels. An example
concerning Brownian noises and a singular kernel is treated

We consider the supernova shock effects, the Mikheyev-Smirnov-Wolfenstein
(MSW) effects, the collective effects, and the Earth matter effects in the
detection of type II supernova neutrinos on the Earth. It is found that the
event number of supernova neutrinos depends on the neutrino mass hierarchy, the
neutrino mixing angle $\theta_{13}$, and neutrino masses. Therefore, we propose
possible methods to identify the mass hierarchy and acquire information about
$\theta_{13}$ and neutrino masses by detecting supernova neutrinos. We apply
these methods to some current neutrino experiments.

We study the adiabatic quantum dynamics of an anisotropic spin-1 XY chain
across a second order quantum phase transition. The system is driven out of
equilibrium by performing a quench on the uniaxial single-spin anisotropy, that
is supposed to vary linearly in time. We show that, for sufficiently large
system sizes, the excess energy after the quench admits a non trivial scaling
behavior that is not predictable by standard Kibble-Zurek arguments for
isolated critical points or extended critical regions. This emerges from a
competing effect of many accessible low-lying excited states, inside the whole
continuous line of critical points.
|
We establish an extension of Liouville's classical representation theorem for
solutions of the partial differential equation $\Delta u=4 e^{2u}$ and combine
this result with methods from nonlinear elliptic PDE to construct holomorphic
maps with prescribed critical points and specified boundary behaviour. For
instance, we show that for every Blaschke sequence $\{z_j\}$ in the unit disk
there is always a Blaschke product with $\{z_j\}$ as its set of critical
points. Our work is closely related to the Berger-Nirenberg problem in
differential geometry.

We consider CP-violating effects in tau->K pi pi nu_tau, assuming that a
charged Higgs boson provides a new amplitude that can interfere with the usual
Standard Model amplitude. We consider four CP-odd observables -- the regular
rate asymmetry, two modified rate asymmetries and a triple-product asymmetry.
The regular rate asymmetry is expected to be small because it requires the
interference of the new physics amplitude with the standard model amplitude
containing the hadronic scalar form factor. The other CP asymmetries may be
more promising in terms of their new physics reach. Numerical estimates
indicate that the maximum obtainable values for the modified and triple-product
asymmetries are on the order of a percent.

We find for g at most 5 a stratification of depth g-2 of the moduli space of
curves M_g with the property that its strata are affine and the classes of
their closures provide a Q-basis for the Chow ring of M_g. The first property
confirms a conjecture of one of us. The way we establish the second property
yields new (and simpler) proofs of theorems of Faber and Izadi which, taken
together, amount to the statement that in this range the Chow ring is generated
by the lambda-class.

Recently there have been significant interests in the spin hydrodynamic
generation phenomenon from multiple disciplines of physics. Such phenomenon
arises from global polarization effect of microscopic spin by macroscopic fluid
rotation and is expected to occur in the hot quark-gluon fluid (the ``subatomic
swirl'') created in relativistic nuclear collisions. This was indeed discovered
in experiments which however revealed an intriguing puzzle: a polarization
difference between particles and anti-particles. We suggest a novel application
of a general connection between rotation and magnetic field: a magnetic field
naturally arises along the fluid vorticity in the charged subatomic swirl. We
establish this mechanism as a new way for generating long-lived in-medium
magnetic field in heavy ion collisions. Due to its novel feature, this new
magnetic field provides a nontrivial explanation to the puzzling observation of
a difference in spin hydrodynamic generation for particles and anti-particles
in heavy ion collisions.

We consider a class of doubly weighted rank-based estimating methods for the
transformation (or accelerated failure time) model with missing data as arise,
for example, in case-cohort studies. The weights considered may not be
predictable as required in a martingale stochastic process formulation. We
treat the general problem as a semiparametric estimating equation problem and
provide proofs of asymptotic properties for the weighted estimators, with
either true weights or estimated weights, by using empirical process theory
where martingale theory may fail. Simulations show that the outcome-dependent
weighted method works well for finite samples in case-cohort studies and
improves efficiency compared to methods based on predictable weights. Further,
it is seen that the method is even more efficient when estimated weights are
used, as is commonly the case in the missing data literature. The Gehan
censored data Wilcoxon weights are found to be surprisingly efficient in a wide
class of problems.

Pretty good for low frequency
I just got these and used them this weekend to block out the Karaoke noise coming from a Bar on my block. I am used to City noise, but this is a whole other nuisance. I have a white noise machine that blocks out the (very bad) singing but I couldn't block out the bass. I put these on and in combo with the white noise, I could barely hear it. It was enough to allow me to go to sleep. Of course, these are not meant to be cozy for sleeping and you can only sleep on your back, but hey, you gotta do what you gotta do. When you are desperate to sleep, you will literally try anything. I'm sure they look stupid, but I don't care because I was asleep. They fit my head tightly, so I'm sure if I wore them for a long time I would get a headache but the bar closes at 1am. I just woke up in the middle of the night and removed them. Works for me.

Bad product and bad information in Amazon Page
I bought this product in July 24 2019, and work for a couple of week, right now the coffee out cold or a few hot. The Amazon support are very friendly but the product no working. The manual said the product not working over 4000 feet, but this information are no showing in Amazon web page.

We present a study of star forming regions and its demographics in the nearby
dwarf irregular galaxy WLM using the Ultra-Violet Imaging Telescope (UVIT)
multi band observations in three filters F148W, N245M and N263M. We find that
the UV emission is extended at least up to 1.7 kpc, with the NUV emission more
extended than the FUV. We create UV color maps ((F148W$-$N245M) and
(F148W$-$N263M)) to study the temperature morphology of young stellar complexes
with the help of theoretical models. We identify several complexes with
temperature T $>$ 17500 K which are likely to be the OB associations present in
the galaxy. These complexes show good spatial correlation with the H$\alpha$
emitting regions, H$~$I distribution and HST detected hot stars. The hot star
forming regions are found to be clumpy in nature and show a hierarchical
structure, with sizes in the range of 4 - 50 pc, with a large number with sizes
$<$ 10 pc. The south western part of the galaxy shows many hot star forming
regions, high level of H$\alpha$ emission and low column density of H$~$I which
altogether denote a vigorous recent star formation. WLM is likely to have a
large fraction of low mass compact star forming regions with mass M $< 10^3
M_{\odot}$, in agreement with the size and mass of the CO clouds. We estimate
the star formation rate of WLM to be $\sim$ 0.008 $M_{\odot}/yr$, which is
similar to the average value measured for nearby dwarf irregular galaxies.

If blue fire is hotter than red fire because blue light has a higher frequency and therefore more energy, then why is the hottest fire white? It seems like it should it should be violet. Or is the white the absence of visible light because the particles are excited above the visible spectrum?

We give a technique to reduce the error probability of quantum algorithms
that determine whether its input has a specified property of interest. The
standard process of reducing this error is statistical processing of the
results of multiple independent executions of an algorithm. Denoting by $\rho$
an upper bound of this probability (wlog., assume $\rho \le \frac{1}{2}$),
classical techniques require $O(\frac{\rho}{[(1-\rho) - \rho]^2})$ executions
to reduce the error to a negligible constant. We investigated when and how
quantum algorithmic techniques like amplitude amplification and estimation may
reduce the number of executions. On one hand, the former idea does not directly
benefit algorithms that can err on both yes and no answers and the number of
executions in the latter approach is $O(\frac{1}{(1-\rho) - \rho})$. We propose
a novel approach named as {\em Amplitude Separation} that combines both these
approaches and achieves $O(\frac{1}{\sqrt{1-\rho} - \sqrt{\rho}})$ executions
that betters existing approaches when the errors are high.
In the Multiple-Weight Decision Problem, the input is an $n$-bit Boolean
function $f()$ given as a black-box and the objective is to determine the
number of $x$ for which $f(x)=1$, denoted as $wt(f)$, given some possible
values $\{w_1, \ldots, w_k\}$ for $wt(f)$. When our technique is applied to
this problem, we obtain the correct answer, maybe with a negligible error,
using $O(\log_2 k \sqrt{2^n})$ calls to $f()$ that shows a quadratic speedup
over classical approaches and currently known quantum algorithms.

JUNK
This is a piece of junk; do not buy. For starters, the "instructions" are largely incomprehensible and obviously written by someone who barely commands the English language. The Bluetooth function is spotty at best- several attempts were required before a connection could be achieved- and quit connecting to my headphones altogether after 3 weeks of use. The touchscreen requires at least a half dozen swipes before it will respond to any function. The wristband attachment is an absolute joke in that the button clasp is difficult to secure and then easily pops loose- meaning you lose your device. Spend your money elsewhere.

The present paper provides a general overview of the asteroseismic potential
of delta Scuti stars in clusters, in particular focusing on convection
diagnostics. We give a summarise of the last results obtained by the authors
for the Praesepe cluster of which five delta Scuti stars are analysed. In that
work, linear analysis is confronted with observations, using refined
descriptions for the effects of rotation on the determination of the global
stellar parameters and on the adiabatic oscillation frequency computations. A
single, complete, and coherent solution for all the selected stars is found,
which lead the authors to find important restrictions to the convection
description for a certain range of effective temperatures. Furthermore, the
method used allowed to give an estimate of the global parameters of the
selected stars and constrain the cluster.

We establish the existence of Nevanlinna domains with large boundaries. In
particular, these domains can have boundaries of positive planar measure. The
sets of accessible points can be of any Hausdorff dimension between $1$ and
$2$. As a quantitative counterpart of these results, we construct rational
functions univalent in the unit disc with extremely long boundaries for a given
amount of poles.

We consider generic derivative corrections to the Einstein gravity and find
new classes of theories without ghost around the Minkowski background by means
of an extension of the spacetime geometry. We assume the Riemann-Cartan
geometry, i.e. a geometry with a non-vanishing torsion, and consider all
possible terms in the Lagrangian up to scaling dimension four. We first clarify
the number, spins, and parities of all particle species around the Minkowski
background and find that some of those particle species are ghosts for generic
choices of parameters. For special choices of the parameters, on the other
hand, those would-be ghosts become infinitely heavy and thus can be removed
from the physical content of particle species. Imposing the conditions on the
coupling constants to eliminate the ghosts, we find new quadratic curvature
theories which are ghost-free around the Minkowski background for a range of
parameters. A key feature of these theories is that there exist a non-ghost
massive spin-2 particle and a non-ghost massive spin-0 particle in the graviton
propagator, as well as the massless spin-2 graviton. In the limit of the
infinite mass of the torsion, the Riemann-Cartan geometry reduces to the
Riemannian geometry and thus the physical content of particle species coincides
with that of the well-known quadratic curvature theory in the metric formalism,
i.e. a massive spin-2 ghost, a massive spin-0 particle and the massless spin-2
graviton. Ghost-freedom therefore sets, besides other constraints, an upper
bound on the mass of the torsion. In addition to the above mentioned particle
species, the ghost-free theory contains either the set of a massive spin-1 and
a massive spin-0 (Class I) or a couple of spin-1 (Class II). These additional
particle species mediate gravity sourced by the spin of matter fields.

We investigate the multiplicity fluctuations observed in high-energy nuclear
collisions attributing them to intrinsic fluctuations of temperature of the
hadronizing system formed in such processes. To account for these fluctuations
we replace the usual Boltzmann-Gibbs (BG) statistics by the non-extensive
Tsallis statistics characterized by the nonextensivity parameter q, with |q-1|
being a direct measure of fluctuations. In the limit of vanishing fluctuations,
q --> 1 and Tsallis statistics converges to the usual BG. We evaluate the
nonextensivity parameter q and its dependence on the hadronizing system size
from the experimentally observed collision centrality dependence of the mean
multiplicity, <N>, and its variance, Var(N). We attribute the observed system
size dependence of q to the finiteness of the hadronizing source with q = 1
corresponding to an infinite, thermalized source with a fixed temperature, and
with q > 1 (which is observed) corresponding to a finite source in which both
the temperature and energy fluctuate.

At the heart of recent progress in AdS/CFT is the question of subregion
duality, or entanglement wedge reconstruction: which part(s) of the boundary
CFT are dual to a given subregion of the bulk? This question can be answered by
appealing to the quantum error correcting properties of holography, and it was
recently shown that robust bulk (entanglement wedge) reconstruction can be
achieved using a universal recovery channel known as the twirled Petz map. In
short, one can use the twirled Petz map to recover bulk data from a subset of
the boundary. However, this map involves an averaging procedure over bulk and
boundary modular time, and hence it can be somewhat intractable to evaluate in
practice. We show that a much simpler channel, the Petz map, is sufficient for
entanglement wedge reconstruction for any code space of fixed finite dimension
- no twirling is required. Moreover, the error in the reconstruction will
always be non-perturbatively small. From a quantum information perspective, we
prove a general theorem extending the use of the Petz map as a general-purpose
recovery channel to subsystem and operator algebra quantum error correction.

Things happen, I suppose I just got a bad one.
It simply did not work. I turned on the water. By the time I went back into the motorhome the floor was flooded and the carpet was soaked because the valve does not shut off. Amazon took care of the cost of the valve but I have the cost of the clean up.

Reinforcement Learning (RL) has demonstrated a huge potential in learning
optimal policies without any prior knowledge of the process to be controlled.
Model Predictive Control (MPC) is a popular control technique which is able to
deal with nonlinear dynamics and state and input constraints. The main drawback
of MPC is the need of identifying an accurate model, which in many cases cannot
be easily obtained. Because of model inaccuracy, MPC can fail at delivering
satisfactory closed-loop performance. Using RL to tune the MPC formulation or,
conversely, using MPC as a function approximator in RL allows one to combine
the advantages of the two techniques. This approach has important advantages,
but it requires an adaptation of the existing algorithms. We therefore propose
an improved RL algorithm for MPC and test it in simulations on a rather
challenging example.

Drug trials should be sequestered and not conducted by those who stand to profit.
Our government should insist that in order to gain approval at least some trials must be conducted in Canada paid for by the sponsor but arranged through a disinterested third party perhaps a crown corporation or non-profit established for this purpose.

We demonstrate the implications of Efimov physics in the recently measured
recombination rate of Cesium-133 atoms. By employing previously calculated
results for the energy dependence of the recombination rate of Helium-4 atoms,
we obtain three independent scaling functions that are capable of describing
the recombination rates over a large energy range for identical bosons with
large scattering length. We benchmark these and previously obtained scaling
functions by successfully comparing their predictions with full atom-dimer
phase shift calculations with artificial Helium-4 potentials yielding large
scattering lengths. Exploiting universality, we finally use these functions to
determine the 3-body recombination rate of Cesium-133 atoms with large positive
scattering length, compare our results to experimental data obtained by the
Innsbruck group and find excellent agreement.

This is not a good yoga towel
This is not a good yoga towel. I didn't like the fabric. It says it has a good grip, but it wasn't the case. My hands and feet were a bit dry and they got stuck to the towel and it's very uncomfortable to do yoga on..

Recent advances in contextual bandit optimization and reinforcement learning
have garnered interest in applying these methods to real-world sequential
decision making problems. Real-world applications frequently have constraints
with respect to a currently deployed policy. Many of the existing
constraint-aware algorithms consider problems with a single objective (the
reward) and a constraint on the reward with respect to a baseline policy.
However, many important applications involve multiple competing objectives and
auxiliary constraints. In this paper, we propose a novel Thompson sampling
algorithm for multi-outcome contextual bandit problems with auxiliary
constraints. We empirically evaluate our algorithm on a synthetic problem.
Lastly, we apply our method to a real world video transcoding problem and
provide a practical way for navigating the trade-off between safety and
performance using Bayesian optimization.

Saved my rear....Literally!!
Started working from home in a call center type of work. Unfortunately it requires sitting at the computer for more hours than I'm used to so my rump/tail bone would start hurting. Since getting this I can comfortably sit thru linger shifts and even elevate my feet without getting tailbone pain.

An effective characterization of chaotic conservative Hamiltonian systems in
terms of the curvature associated with a Riemannian metric tensor derived from
the structure of the Hamiltonian has been extended to a wide class of potential
models of standard form through definition of a conformal metric. The geodesic
equations reproduce the Hamilton equations of the original potential model
through an inverse map in the tangent space. The second covariant derivative of
the geodesic deviation in this space generates a dynamical curvature, resulting
in (energy dependent) criteria for unstable behavior different from the usual
Lyapunov criteria. We show here that this criterion can be constructively used
to modify locally the potential of a chaotic Hamiltonian model in such a way
that stable motion is achieved. Since our criterion for instability is local in
coordinate space, these results provide a new and minimal method for achieving
control of a chaotic system.

Because LSC attorneys must withdraw whenever a question of a welfare statute's validity arises, an individual could not obtain joint representation so that the constitutional challenge would be presented by a non-LSC attorney, and other, a504(a)(16) is necessary to define the scope and contours of the federal program, a condition that ensures funds can be spent for those cases most immediate to congressional concern.

Curriculum learning in reinforcement learning is used to shape exploration by
presenting the agent with increasingly complex tasks. The idea of curriculum
learning has been largely applied in both animal training and pedagogy. In
reinforcement learning, all previous task sequencing methods have shaped
exploration with the objective of reducing the time to reach a given
performance level. We propose novel uses of curriculum learning, which arise
from choosing different objective functions. Furthermore, we define a general
optimization framework for task sequencing and evaluate the performance of
popular metaheuristic search methods on several tasks. We show that curriculum
learning can be successfully used to: improve the initial performance, take
fewer suboptimal actions during exploration, and discover better policies.

In this work, a path integral Car-Parrinello molecular dynamics simulation of
liquid water is performed. It is found that the inclusion of nuclear quantum
effects systematically improves the agreement of first principles simulations
of liquid water with experiment. In addition, the proton momentum distribution
is computed utilizing a recently developed open path integral molecular
dynamics methodology. It is shown that these results are in good agreement with
neutron Compton scattering data for liquid water and ice.

Based on the statistical theory of light nucleus reactions (STLN), the
description of the complicated emission processes of proton and light composite
charged particles are further improved through considering the effects of
Coulomb barriers both in incident and different outgoing reaction channels. And
the analysis of the reaction channels including the sequential and simultaneous
emission processes for $p + ^7$Li reaction is performed in detail. So the
partial spectra of all of outgoing particles are also obtained for different
reaction processes. The calculated double differential cross sections of total
outgoing proton, deuteron and triton at $E_p = 14$ MeV agree well with the
available experimental data for different outgoing angles. The ENDF-6 formatted
data, which includes all of the reaction cross sections, elastic angular
distributions, double differential cross sections of nucleon and light
composite charged particles for $p + ^7$Li reaction, are also obtained by PUNF
code.

Adsorbed molecular films provide two-dimensional systems that show various
emergent phenomena that are not observed in bulk counterparts. We have measured
the elasticity of thin neon films adsorbed on porous glass down to 1 K by the
torsional oscillator technique. The shear modulus of a neon film anomalously
increases at low temperatures with excess dissipation. This behavior indicates
a crossover from a soft (fluidlike) state at high temperatures to a stiff
(solidlike) state at low temperatures. The temperature dependence of the
anomaly is qualitatively similar to that of the elastic anomaly of helium films
found in our recent study. The dissipation peak temperature, however, becomes
constant at about 5 K, contrary to the case of helium, in which it decreases to
0 K at a critical coverage of a quantum phase transition between a gapped
localized phase and a mobile (superfluid) phase. It is concluded that neon
films behave as a classical system that does not show a quantum phase
transition or superfluidity, although the films may be strongly supercooled to
temperatures much lower than the bulk triple point, 24.6 K. Our results suggest
that the elastic anomaly is a universal phenomenon of atomic or molecular films
adsorbed on disordered substrates.

We adapt the time-evolving block decimation (TEBD) algorithm, originally
devised to simulate the dynamics of 1D quantum systems, to simulate the
time-evolution of non-equilibrium stochastic systems. We describe this method
in detail; a system's probability distribution is represented by a matrix
product state (MPS) of finite dimension and then its time-evolution is
efficiently simulated by repeatedly updating and approximately re-factorizing
this representation. We examine the use of MPS as an approximation method,
looking at parallels between the interpretations of applying it to quantum
state vectors and probability distributions. In the context of stochastic
systems we consider two types of factorization for use in the TEBD algorithm:
non-negative matrix factorization (NMF), which ensures that the approximate
probability distribution is manifestly non-negative, and the singular value
decomposition (SVD). Comparing these factorizations we find the accuracy of the
SVD to be substantially greater than current NMF algorithms. We then apply TEBD
to simulate the totally asymmetric simple exclusion process (TASEP) for systems
of up to hundreds of lattice sites in size. Using exact analytic results for
the TASEP steady state, we find that TEBD reproduces this state such that the
error in calculating expectation values can be made negligible, even when
severely compressing the description of the system by restricting the dimension
of the MPS to be very small. Out of the steady state we show for specific
observables that expectation values converge as the dimension of the MPS is
increased to a moderate size.

In this report, I discuss the current state of the problem of the axial
anomaly in quantum electrodynamics (QED) and quantum chromodynamics (QCD) and
how the axial anomaly is related to the structure of the vacuum in QCD. In QCD,
the vacuum average of the axial anomaly is proportional to a new quantum number
n, the winding number. The axial anomaly condition implies that there are zero
modes of the Dirac equation for a massless quark and that there is spontaneous
breaking of chiral symmetry in QCD, which leads to the formation of a quark
condensate. The axial anomaly can be represented in the form of a sum rule the
structure function in the dispersion representation of the axial -- vector --
vector (AVV) vertex. On the basis of this sum rule, it is calculated the width
of the \pi^0\to 2\gamma decay with an accuracy of 1.5%. It is demonstrated,
that 't Hooft conjecture -- the singularities of the amplitudes calculated in
perturbative QCD on quark-gluon basis should reproduce themselves in
calculations on the hadrons basis -- is not fulfilled generally.

You win some you loose some
It was very easy to put on, no problems there. It definitely adds some bulk to the pen itself which takes away from the sleek design and the comfort of holding it. I have found the pen is not as sensitive to the double tap feature with the case on nor does it charge as fast. The other reviews did state that the magnet isn’t as strong and it’s true so I wasn’t surprised. Over all I purchased this to try and preserve and protect my pencil and this does the trick but it does dull it down some.

Although logarithmic conformal field theories (LCFTs) are known not to
factorise many previous findings have only been formulated on their chiral
halves. Making only mild and rather general assumptions on the structure of an
chiral LCFT we deduce statements about its local non-chiral equivalent. Two
methods are presented how to construct local representations as
subrepresentations of the tensor product of chiral and anti-chiral Jordan
cells. Furthermore we explore the assembly of generic non-chiral correlation
functions from generic chiral and anti-chiral correlators. The constraint of
locality is studied and the generality of our method is discussed.

Nice story, just too short for my tastes
I got this book to read along with my book club. And in reading it I realized that I just don't care for novella length stories. They feel too fast paced to me. That's really just to explain why I only gave three stars. I would say, I liked the concept of fairy tales with more dragons. I also enjoyed the added touch of Snow LITTERALY having skin like snow, hair like a raven and lips like a rose. That was clever.

The 12th animated Disney classic is a reasonable movie told through a simple story. Even though a little dated, it deserves a place in the list of Disney classics.<br /><br />It's not among Disney's top works, but is satisfying. One of Disney's most "simple" works, yes, but keeps a certain magic and enchantment (which old Disney is well known for). This was an important movie because it saved Disney from a delicate situation. If this was a failure, there wouldn't be any more Disney animated classics.<br /><br />"Cinderella" is somehow like a return to Disney's 1st animated classic ("Snow White and the Seven Dwarfs") because it brings back the fairy tale genre. It's not clear where the story takes place, but I suppose it's somewhere in France because this is based in a tale by Charles Perrault.<br /><br />There are plenty of likable characters, such as Cinderella, the Prince, Bruno (the dog), Jaques and Gus (the two main mice), the Fairy Godmother (for a fairy she sure is funny), the birds, the King and the Grand Duke.<br /><br />Jaques is very smart and amusing. I love his voice. Really has that mouse-like quality. Gus might not be that smart, but he's humorous.<br /><br />The King is hilarious, but I think that what makes him so funny is his short temper. The Grand Duke is a very cool chap and funny too. They're two of my favorite characters in this film and responsible for many of the most amusing moments.<br /><br />The Prince is certainly one of the most charming in Disney. No doubt that Prince Philip from "Sleeping Beauty" was inspired on this prince, because they are very similar-looking.<br /><br />On the other hand, Lady Tremaine (the stepmother) isn't supposed to be likable because she's cold, jealous, bitter and cruel. Her daughters (Anastacia and Drizella) aren't much better than her. However, the stepmother isn't as annoying as her ugly and selfish daughters. Cinderella, the main character, has nothing to do with them. Cinderella is gentle, kind, pretty and lovable. By the way, I think her beautiful pink dress is much nicer than the one given by the Fairy Godmother.<br /><br />Lucifer (the cat) is hilariously malicious. The way he walks, sticking up his nose in the air and those arrogant and snobbish facial expressions make him funny. Ironically he's very much like the stepmother when it comes to personality. He always agrees with the stepmother's attitudes towards Cinderella. Lucifer has the right name for him because he's such a devilish and mean cat. Yet, there's nothing annoying about him.<br /><br />The soundtrack is simple but pleasant, although not among Disney's best. The best song in this movie is "Bibiddi Bobiddi Boo".<br /><br />There are plenty of well known talented voice actors in this, such as James MacDonald, Marion Darlington, Eleanor Audley, Verna Felton and Luis Van Rooten.<br /><br />Despite being simple-looking, the movie has good artwork, as well as its nice details, although never something "out-of-this-world". However, the King's palace is a spectacular masterpiece, being truly majestic and colossal.

We study self-interacting dark matter signatures at the Large Hadron
Collider. A light dark photon, mediating dark matter self-interactions, can
bind dark matter particles to form a bound state when they are produced via a
heavy pseduoscalar in $pp$ collisions. The bound state can further annihilate
into a pair of boosted dark photons, which subsequently decay into charged
leptons through a kinetic mixing portal, resulting in striking displaced lepton
jet signals. After adapting the analysis used in the ATLAS experiment, we
explore the reach of the model parameters at the $13~{\rm TeV}$ run with an
integrated luminosity of $300~{\rm fb^{-1}}$. For heavy dark matter, the
displaced lepton jet searches can surpass traditional monojet signals in
setting the lower bound on the pseduoscalar mass. If a positive signal is
detected, we can probe the dark matter mass and the dark coupling constant
after combining both the displaced lepton jet and monojet searches. We further
show the CMS dimuon search can be sensitive to the final state radiation of the
dark photon. Our results demonstrate terrestrial collider experiments
complement astronomical observations of galaxies in the search of the
self-interacting nature of dark matter.

A Terrible Experience
In the bottle, several of the capsules had come apart and the content distributed across the remainder. I realized this the hard way. As I placed a capsule in my mouth, and prior to swallowing, I breathed inward. Thus, I sucked cinnamon and cayenne dust into my lungs. I thought I was going to die. Coughing, burning lungs, eyes watering, etc for about a half hour. I have no idea whether the product is otherwise any good, as I tossed the remainder into the trash.

We examine the faint-end slope of the rest-frame V-band luminosity function
(LF), with respect to galaxy spectral type, of field galaxies with redshift
z<0.5, using a sample of 80,820 galaxies with photometric redshifts in the
Cosmic Evolution Survey (COSMOS) field. For all galaxy spectral types combined,
the LF slope, alpha, ranges from -1.24 to -1.12, from the lowest redshift bin
to the highest. In the lowest redshift bin (0.02<z<0.1), where the magnitude
limit is M(V) ~ -13, the slope ranges from ~ -1.1 for galaxies with early-type
spectral energy distributions (SEDs), to ~ -1.9 for galaxies with
low-extinction starburst SEDs. In each galaxy SED category (Ell, Sbc, Scd/Irr,
and starburst), the faint-end slopes grow shallower with increasing redshift;
in the highest redshift bin (0.4<z<0.5), the slope is ~ -0.5 and ~ -1.3 for
early-types and starbursts respectively. The steepness of alpha at lower
redshift could be qualitatively explained by large numbers of faint dwarf
galaxies, perhaps of low surface brightness, which are not detected at higher
redshifts.

The focus of this paper is on the asymptotics of large-time numbers of
customers in time-periodic Markovian many-server queues with customer
abandonment in heavy traffic. Limit theorems are obtained for the periodic
number-of-customers processes under the fluid and diffusion scalings. Other
results concern limits for general time-dependent queues and for
time-homogeneous queues in steady state.

Well done, but not quite
Great story. Well developed. Even a little bit of the occult. Exciting. But I wish I had not read the last 15 pages. A stretch to tie up all loose ends. Almost like the author had a deadline. I don't need all things tied up, thank you.

In this study, we propose a novel graph neural network called
propagate-selector (PS), which propagates information over sentences to
understand information that cannot be inferred when considering sentences in
isolation. First, we design a graph structure in which each node represents an
individual sentence, and some pairs of nodes are selectively connected based on
the text structure. Then, we develop an iterative attentive aggregation and a
skip-combine method in which a node interacts with its neighborhood nodes to
accumulate the necessary information. To evaluate the performance of the
proposed approaches, we conduct experiments with the standard HotpotQA dataset.
The empirical results demonstrate the superiority of our proposed approach,
which obtains the best performances, compared to the widely used
answer-selection models that do not consider the intersentential relationship.

I have never really been interested in cannibal movies before and up until a couple of months ago i had avoided this genre of movie.<br /><br />I recently had to undergo knee surgery and found i had a lot of time on my hands as i was unable to work, so i decided after seeing almost every horror movie our local video shop had to offer i would take a chance on this.<br /><br />Christ was it a mistake! I have never seen a movie this bad in all my years of being a movie addict. This is just a pile of s**t pasted to a D.V.D disc and sold as a horror movie.<br /><br />I have a lot of respect to other horror fans who can switch their brains off long enough to enjoy this crap, They are more brain dead than i ever will be and that is some achievement! 0/10 and thats generous.

We examine the five-region holographic entropy cone inequalities for the
special case of the AdS$_3$-Vaidya metric for a variety of boundary
configurations. This is done by numerically solving the geodesic equation in
the bulk for various boundary configurations. In all the cases we examine, we
find that all the inequalities are satisfied when the bulk satisfies the null
energy condition, while the inequalities are all violated when the bulk
spacetime violates the null energy condition. A proof of the five-region
holographic entropy cone inequalities for the dynamical bulk case remains an
open problem--our results provide evidence that these inequalities hold for
dynamical bulk spacetimes.

One can only imagine the film Mr. Welles might have finished without the interference of the studio! This film is a flawed Welles, but worth every minute of it because one can see the greatness of perhaps America's best motion picture director of all times!<br /><br />We can see the toll it took on Orson Welles the filming of this movie. The story has a lot of holes in it, perhaps because of the demands of the studio executives that didn't trust the director. <br /><br />It is curious by reading some of the opinions submitted to IMDB that compare Orson Welles with the Coen brothers, Roman Polanski, even Woody Allen, when it should be all of those directors that must be regarded as followers of the great master himself. No one was more original and creative in the history of American cinema than Mr. Welles. Lucky are we to still have his legacy either in retrospective looks such as the one the Film Forum in New York just ended, or his films either on tape or DVD form.<br /><br />Rita Hayworth was never more lovingly photographed than here. If she was a beauty with her red hair, as a blonde, she is just too stunning for words. Everett Sloan and Glenn Anders made an excellent contribution to the movie.<br /><br />The only thing that might have made this film another masterpiece to be added to Orson Welles body of work, was his own appearance in it. Had he concentrated in the directing and had another actor interpret Michael O'Hara, a different film might have been achieved altogether. Orson Welles has to be credited for being perhaps a pioneer in taking the camera away from the studio lot into the street. The visuals in this film are so amazing that we leave the theater after seeing this movie truly impressed for the work, the vision and the talent he gave us.

We present a framework for translating unlabeled images from one domain into
analog images in another domain. We employ a progressively growing
skip-connected encoder-generator structure and train it with a GAN loss for
realistic output, a cycle consistency loss for maintaining same-domain
translation identity, and a semantic consistency loss that encourages the
network to keep the input semantic features in the output. We apply our
framework on the task of translating face images, and show that it is capable
of learning semantic mappings for face images with no supervised one-to-one
image mapping.

Loved the first 3 books
The first 3 books were excellent; well written, characters well developed and credible, story believable. The 4th book was a disappointment; unrealistic, predictable, annoying to read. I was so turned off by the way the 4th story was written that I stopped reading it on more than one occasion. I actually forced myself to complete the book in the hope that it would improve as the story progressed.... no such luck.

Using UBVRI Halpha CCD photometric observations and the archival NIR and
X-ray data, we have carried out a multi-wavelength study of a young star
cluster NGC 7419. An age of 22.5+/-3.0 Myr and a distance of 3230^{+330}_{-430}
pc are derived for the cluster with a higher value of color excess ratio
E(U-B)/E(B-V) than the normal one. There is an evidence for mass segregation in
this dynamically relaxed cluster with mass function slope is in agreement with
the Salpeter value. NIR and Halpha excess support the existence of a young (< 2
Myr) stellar population of Herbig Ae/Be stars (> 3.0 M_sun) indicating a second
episode of star formation in the cluster region. Using XMM-Newton observations,
we found several X-ray sources in the cluster region but none of the Herbig
Ae/Be stars is detected in X-rays. We compare the distribution of upper limits
for Herbig Ae/Be stars with the X-ray distribution functions of the T-Tauri and
the Herbig Ae/Be stars from previous studies, and found that the X-ray emission
level of these Herbig Ae/Be stars is not more than L_X ~5.2 x 10^{30} erg/s,
which is not significantly higher than for the T-Tauri stars. Therefore, X-ray
emission from Herbig Ae/Be stars could be the result of either unresolved
companion stars or a process similar to T-Tauri stars. We report an extended
X-ray emission from the cluster region NGC 7419, with a total L_X estimate of ~
1.8 x 10^31 erg/s/arcmin^2. Investigation of dust and CO map of 1 degree region
around the cluster indicates the presence of a foreground dust cloud which is
most likely associated with star forming region Sh2-154. This cloud harbors
uniformly distributed pre main sequence stars (0.1-2.0M_sun) and the star
formation in this cloud depend mostly upon the primordial fragmentation.

The primary physics goals of a high luminosity e+e- flavor factory are
discussed, including the possibilities to perform detailed studies of the CKM
mechanism of quark mixing, and constrain virtual Higgs and non-standard model
particle contributions to the dynamics of rare B_{u,d,s} decays. The large
samples of D mesons and tau leptons produced at a flavor factory will result in
improved sensitivities to rare D processes - mixing, CP violation and rare
decays - and lepton flavor violation searches, respectively. Recent
developments in accelerator physics have demonstrated the feasibility to build
an accelerator that can achieve luminosities of ~10^36 cm-2 s^-1 at sqrt{s}=10
GeV. The capablity to run at sqrt{s}=3.770 GeV with luminosity of ~10^35 cm^-2
s^-1 is included in the initial design. This report emphasizes the charm
physics that can be probed at a Super Flavor Factory.

In this paper, we prove that a binary definite quadratic form over F_q[t],
where q is odd, is completely determined up to equivalence by the polynomials
it represents up to degree 3m-2, where m is the degree of its discriminant. We
also characterize, when q>13, all the definite binary forms over F_q[t] that
have class number one.

Orientifolds of type II string theory admit a certain set of generalized
NS-NS fluxes, including not only the three-form field strength H, but also
metric and non-geometric fluxes, which are related to H by T-duality. We
describe in general how these fluxes appear as parameters of an effective N=1
supergravity theory in four dimensions, and in particular how certain
generalized NS-NS fluxes can act as charges for R-R axions, leading to D-term
contributions to the effective scalar potential. We illustrate these phenomena
in type IIB with the example of a certain orientifold of T^6/Z_4.

Relief based algorithms have often been claimed to uncover feature
interactions. However, it is still unclear whether and how interaction terms
will be differentiated from marginal effects. In this paper, we propose
IMMIGRATE algorithm by including and training weights for interaction terms.
Besides applying the large margin principle, we focus on the robustness of the
contributors of margin and consider local and global information
simultaneously. Moreover, IMMIGRATE has been shown to enjoy attractive
properties, such as robustness and combination with Boosting. We evaluate our
proposed method on several tasks, which achieves state-of-the-art results
significantly.

Okay, I was bored and decided to see this movie. But I think the main thing that brought this movie down was that there would be a hour of footage, then basically that same hour repeated 4 times. It consists of 1. Gathering the troops and discussing the attack plan, 2. Flashbacks to the men's wives 3. The approach of the troops marching in a long line 4. Men running up hill and shooting, usually the first getting shot in the head then 3 other men rescuing him. 5. Defeat of the enemy and calling to base to tell of success 6. Men flashing back to wives and singing 10 minute songs. That was the basic movie, and that same order of events happened about 4 or 5 times. and every time it did a flashback to the wives, it would show the man, then his wife and him. There were about 10 men or more who would have a flashback so this took up tons of time. Other than that, the men couldn't kill their enemy except with either bayonets or grenades. I liked the music and there was a lot of action, though the action was repetitive. Overall, I probably wouldn't see it again, but it wasn't too horrible.

It was AMAZING. As a librarian and an attendee at the New York Library Association's Vitality Fund Event on Thursday night, October 18, I was privileged to see a pre-release screening of the new movie, The Kite Runner. The release of the movie has been delayed because of concerns about the welfare of the child actors involved. I am grateful that the NYLA event was allowed to go on as planned.<br /><br />Regarding the movie, I feel it was masterfully done. It had as much impact on me, I think, as Stanley Kubrik's A Clockwork Orange, even though it is much less graphic - MUCH less. There is no comparison between the horrendous, shocking violence and rape shown in A Clockwork Orange and the small amount of violence actually shown in Kite Runner; only the subject matter and the implications for the human psyche are comparable. (I have written more details about the violence and child rape and how it was handled on my MySpace blog.) My overall impression was that this film was fantastic; one of the best-made films I have seen. The depiction of the Afghani boys flying their kites captured some of the beauty and grace of an art form unknown to most of the world. The subject matter is intensely serious, and the movie carries the emotions of the audience into that subject matter without many jarring "Hollywood touches" which have ruined other movies. Although the overturned cart of pomegranates was an obvious bit of symbolism (to me).<br /><br />Finally, I must mention the excellence of the sound track. The recitation by the boy of poetry by Rumi as two main characters are fleeing the country during the Russian invasion - under terrifying circumstances - truly showed the power of those poems. I urge anyone watching to disregard the subtitles in that scene to the extent that you can, and just listen to the beauty of the language. I don't even know what language Amir is quoting, whether his normal Dari Persian dialect is the same as Rumi's original Persian dialect. Also, please note the sound heard every time a kite line is cut. I found it a profound, distinctive sound, though the librarians who were with me did not notice it at all. I can't help but wonder if kites actually make a sound like that when they are "cut", or if it gives a sense of the vibration/sound experienced by the kite flyer during competition.

Renee Zellweger is Betty, a Kansas waitress who wants to be a nurse, who is infatuated with a soap opera actor (Greg Kinnear), and who is married to Del, a cheating, stupid male chauvinist who's trying to sell some stolen drugs. Unfortunately for him, he gets brutally, bloodily murdered instead, while Betty secretly watches. It leaves her unhinged, believing that Kinnear is really the character he plays, Dr. David Ravell, and that she is his RN ex-fiancée. She heads for LA to find her lost love, not knowing the stolen drugs are in her trunk. Pursuing her are Charlie and Wesley (Morgan Freeman and Chris Rock respectively), the hit men who inadvertently killed Del before they found out where the drugs were hidden. They pursue her across the country, while Charlie gradually falls in love with his image of her.<br /><br />And in LA, things get totally bizarre, as no one realizes that Betty is delusional. Alternately funny and touching, this movie is almost perfect. Stop reading commentaries and go see it.

We present new X-ray timing and spectral observations of PSR J1930+1852, the
young energetic pulsar at the center of the non-thermal supernova remnant
G54.1+0.3. Using data obtained with the Rossi X-ray Timing Explorer and Chandra
X-ray observatories we have derived an updated timing ephemeris of the 136 ms
pulsar spanning 6 years. During this interval, however, the period evolution
shows significant variability from the best fit constant spin-down rate of
$\dot P = 7.5112(6) \times 10^{-13}$ s s$^{-1}$, suggesting strong timing noise
and/or glitch activity. The X-ray emission is highly pulsed ($71\pm5%$
modulation) and is characterized by an asymmetric, broad profile ($\sim 70%$
duty cycle) which is nearly twice the radio width. The spectrum of the pulsed
emission is well fitted with an absorbed power law of photon index $\Gamma =
1.2\pm0.2$; this is marginally harder than that of the unpulsed component. The
total 2-10 keV flux of the pulsar is $1.7 \times 10^{-12}$ erg cm$^{-2}$
s$^{-1}$. These results confirm PSR J1930+1852 as a typical Crab-like pulsar.

Socially exchanged fluids, like seminal fluid and milk, allow individuals to molecularly influence conspecifics. Many social insects have a social circulatory system, where food and endogenously produced molecules are transferred mouth-to-mouth (stomodeal trophallaxis), connecting all the individuals in the society. To understand how these endogenous molecules relate to colony life, we used quantitative proteomics to investigate the trophallactic fluid within colonies of the carpenter ant Camponotus floridanus. We show that different stages of the colony life cycle circulate different types of proteins: young colonies prioritize direct carbohydrate processing; mature colonies prioritize accumulation and transmission of stored resources. Further, colonies circulate proteins implicated in oxidative stress, ageing, and social insect caste determination, potentially acting as superorganismal hormones. Brood-caring individuals that are also closer to the queen in the social network (nurses) showed higher abundance of oxidative stress-related proteins. Thus, trophallaxis behavior provides a mechanism for distributed metabolism in social insect societies.

Observational data from the Fermi Gamma-ray Space Telescope are analyzed with
a goal in mind to look for variations in gamma-ray flux from young shell-like
supernova remnants. Uniform methodological approach is adopted for all SNRs
considered. G1.9+0.3 and Kepler SNRs are not detected. The light curves of
Cas~A and Tycho SNRs are compatible with the steady GeV flux during the recent
ten years, as also X-ray and radio fluxes. Less confident results on SN1006 and
SN1987A are discussed.

We consider single-source single-sink (ss-ss) multi-hop networks, with
slow-fading links and single-antenna half-duplex relays. We identify two
families of networks that are multi-hop generalizations of the well-studied
two-hop network: K-Parallel-Path (KPP) networks and layered networks. KPP
networks can be viewed as the union of K node-disjoint parallel relaying paths,
each of length greater than one. KPP networks are then generalized to KPP(I)
networks, which permit interference between paths and to KPP(D) networks, which
possess a direct link from source to sink. We characterize the DMT of these
families of networks completely for K > 3. Layered networks are networks
comprising of relaying layers with edges existing only within the same layer or
between adjacent layers. We prove that a linear DMT between the maximum
diversity d_{max} and the maximum multiplexing gain of 1 is achievable for
fully-connected layered networks. This is shown to be equal to the optimal DMT
if the number of layers is less than 4. For multi-antenna KPP and layered
networks, we provide an achievable DMT region.
For arbitrary ss-ss single-antenna directed-acyclic full-duplex networks, we
prove that a linear tradeoff between maximum diversity and maximum multiplexing
gain is achievable. All protocols in this paper are explicit and use only
amplify and forward (AF) relaying. We also construct codes with short
block-lengths based on cyclic division algebras that achieve the optimal DMT
for all the proposed schemes. Two key implications of the results in the paper
are that the half-duplex constraint does not entail any rate loss for a large
class of networks and that simple AF protocols are often sufficient to attain
the optimal DMT.

If the majority of Polynesians apposed Annexation Mary, it begs the question: Why would they continued to elect Polynesian candidates that were?
"Be it resolved, by the Senate and House of Representatives of the Territory of Hawaii, that the Congress of the United States...is hereby respectfully requested to pass an Act enabling the people of this Territory to meet in convention and frame and adopt a State Constitution where under this Territory may be admitted as a State into the Union". This was the first action of the 1903 Hawaii Legislature, adopted unanimously by the Senate and Polynesian- Hawaiian dominated House, and delivered to the U.S. Congress by our elected delegate to the U.S. Congress by Polynesian Prince Kuhio Kalaniana'ole.
Again, if the Polynesians of the time in Hawaii were against being part of the U.S. they had a funny way of showing it! Only a couple years after annexation they wanted full statehood.

Much work has been devoted to analysing thermodynamic models for solid
dispersions with a view to identifying regions in the phase diagram where
amorphous phase separation or drug recrystallization can occur. However,
detailed partial differential equation non-equilibrium models that track the
evolution of solid dispersions in time and space are lacking. Hence theoretical
predictions for the timescale over which phase separation occurs in a solid
dispersion are not available. In this paper, we address some of these
deficiencies by (i) constructing a general multicomponent diffusion model for a
dissolving solid dispersion; (ii) specializing the model to a binary
drug/polymer system in storage; (iii) deriving an effective concentration
dependent drug diffusion coefficient for the binary system, thereby obtaining a
theoretical prediction for the timescale over which phase separation occurs;
and (iv) presenting a detailed numerical investigation of the HPMCAS/Felodipine
system assuming a Flory-Huggins activity coefficient. The numerical simulations
exhibit numerous interesting phenomena, such as the formation of polymer
droplets and strings, Ostwald ripening/coarsening, phase inversion, and
droplet-to-string transitions.

This is a nice little horror flick that fans of indie films will really appreciate. It has good acting, lots of gore, and a decent plot. One will be reminded of movies like The Hills Have Eyes and Pumpkinhead. It's obvious that the budget was not all that big, but the film really makes up for it with atmosphere and solid performances by the actors, which seems to be lacking in a lot of today's big budget special effects-filled films. The film really moves along and there is excellent direction and good camera work. There are no wasted scenes, so the film's length is a bit short. In addition, it looks like the ending leaves an opening for a sequel, which would be very interesting as well. So grab some popcorn, turn down the lights and enjoy this one.

Eh. Its ok
Although the functions are great, they do not go off the way they should. My dog will get a good 3-4 barks out before the collar even gives the warning beeps. The collar will also beep/vibrate when my dog just shakes his head and not bark. The main reason my dog doesnt bark as much when wearing it is because he knows what it does.

In this paper, we introduce a method of imposing asymmetric conditions on the
velocity vector with respect to independent variables and a method of moving
frame for solving the three dimensional Navier-Stokes equations. Seven families
of non-steady rotating asymmetric solutions with various parameters are
obtained. In particular, one family of solutions blow up at any point on a
moving plane with a line deleted, which may be used to study turbulence. Using
Fourier expansion and two families of our solutions, one can obtain
discontinuous solutions that may be useful in study of shock waves. Another
family of solutions are partially cylindrical invariant, contain two parameter
functions of $t$ and structurally depend on two arbitrary polynomials, which
may be used to describe incompressible fluid in a nozzle. Most of our solutions
are globally analytic with respect to spacial variables.

For linear time-invariant systems having a state matrix with uncertain sign,
we formulate a minimax adaptive control problem as a zero sum dynamic game.
Explicit expressions for the optimal value function and the optimal control law
are given in terms of a Riccati equation. The optimal control law is adaptive
in the sense the past data is used to estimate the uncertain sign for
prediction of future dynamics. Once the sign has been estimated, the controller
behaves like standard H-infinity optimal state feedback.

Removing the hair is a struggle
Does it brush well? Yes. Does the job of brushing my cat and dog. Can you actually get the hair out of the brush? Not really, I ended up using a fork to try and scrape off the hair or risk poking my fingers, trying to get the hair out.

For any countable group with infinite conjugacy classes we construct a family
of forests on the group. For each of them there is a random walk on the group
with the property that its sample paths almost surely converge to the geometric
boundary of the forest in a way that resembles the simple random walks on
trees. It allows us to identify the Poisson boundary of the random walk with
the boundary of the forest and to show that the group action on the Poisson
boundary is free (which, in particular, implies non-triviality of the Poisson
boundary). As a consequence we obtain that any countable group carries a random
walk such that the stabilizer of almost every point of the Poisson boundary
coincides with the hyper-FC-centre of the group, and, more generally, we
characterize all normal subgroups which can serve as the pointwise stabilizer
of the Poisson boundary of a random walk on a given countable group. Our work
is a development of a recent result of Frisch - Hartman - Tamuz - Vahidi
Ferdowsi who proved that any group which is not hyper-FC-central admits a
measure with a non-trivial Poisson boundary.

"they don't have to recuse themselves when voting on tax bills that affect thier company"
That's not entirely accurate, Mucky. They do have to recuse themselves, and IIRC they did, but there is little accountability to who disputes a recusal _and_ the current system requires unanimous consent for a recusal so that it never has a chance to last. With two employees in either chamber all it takes is for one to anonymously dispute a recusal of the other for it fail. That's one of the reasons why I hope to see Grenn's bill to change the procedure gain some traction this session.

Next year they will use the pfd and taxes to buy the building on 4th. Taking the pfd and adding taxes is the lazy budget fix, its time to go line by line dime by dime and ask how would the constituents feel about this spending. Its easier to pit rich v poor against each other when you call for taxes than to actually represent the people. Rich and poor will agree buying a bank building is wasted state money, we should not give tax credits for oil companies losses out of state, the super projects need to end and we should not be cutting the legislative budgets their travel budgets and end the perdiem. That's just the start. Call them tell them override the pfd veto take taxes off the table and hire a group of forensic account's to publish every dime and yes every oil tax credit or they are fired. Its time to actually represent the people
