I just watched this film, and I have to say it surprised me. It was very well done, with good acting and a deep look at high school students from Japan, in adolescent love.<br /><br />The look and feel is a lot different from many movies, and you can easily get into the film. Much of the emphasis seems to be in the story itself, which is extremely subtle. The main theme and relations with other characters are a bit complex. But the the overall sense of realism and dimensions still pulls you in.<br /><br />A main draw back is of course, those who like something simple. Which is not here. You have to be open to many things, including a new culture, to get more into the film.<br /><br />I did enjoy this film though. It is worth watching.

Well made, super comfy
I really love this sleep sack for my (tall) 11 month old -- it's perfect now that it's getting colder and very well made. We are in Northern California so our house drops a good 10 degrees between bedtime and morning and on colder nights she's warm and snuggly wearing this and a long sleeved onsie. It has tons of room to grow into, too. The only reason for knocking off a star is the fabric on the top to fold over the zipper isn't quite big enough so the zipper winds up creeping out and she sometimes plays with it, increasing the chance that, as she gets older, she may figure out how to unzip it. A simple change to make the flap bigger or add a snap tab over the zipper would solve it. Regardless, I'm buying a second one! Can't beat the price as well.

AIMS: The properties of the very high energy (VHE; E>100 GeV) gamma-ray
emission from the high-frequency peaked BL Lac PG 1553+113 are investigated. An
attempt is made to measure the currently unknown redshift of this object.
METHODS: VHE Observations of PG 1553+113 were made with the High Energy
Stereoscopic System (HESS) in 2005 and 2006. H+K (1.45-2.45 micron)
spectroscopy of PG 1553+113 was performed in March 2006 with SINFONI, an
integral field spectrometer of the ESO Very Large Telescope (VLT) in Chile.
RESULTS: A VHE signal, ~10 standard deviations, is detected by HESS during
the 2 years of observations (24.8 hours live time). The integral flux above 300
GeV is (4.6 +- 0.6{stat} +- 0.9{syst}) x 10^{-12} cm^{-2} s^{-1}, corresponding
to ~3.4% of the flux from the Crab Nebula above the same threshold. The
time-averaged energy spectrum is measured from 225 GeV to ~1.3 TeV, and is
characterized by a very soft power law (photon index of Gamma = 4.5 +-
0.3{stat} +- 0.1{syst}). No evidence for any flux or spectral variations is
found on any sampled time scale within the VHE data. The redshift of PG
1553+113 could not be determined. Indeed, even though the measured SINFONI
spectrum is the most sensitive ever reported for this object at near infrared
wavelengths, and the sensitivity is comparable to the best spectroscopy at
other wavelengths, no absorption or emission lines were found in the H+K
spectrum presented here.

Sad thing is there's not even a reason for the Republicans to push so hard - they control both houses and have Trump in the White House. And they seem to have a lock on the stupid vote - so, let some decent people speak. Republicans will still get their "christian" way.

We consider the interaction of two weak probe fields of light with an atomic
ensemble coherently driven by two pairs of standing wave laser fields in a
tripod-type linkage scheme. The system is shown to exhibit a Dirac-like
spectrum for light-matter quasi-particles with multiple dark-states, termed
spinor slow-light polaritons (SSP). They posses an "effective speed of light"
given by the group-velocity of slow-light, and can be made massive by inducing
a small two-photon detuning. Control of the two-photon detuning can be used to
locally vary the mass including a sign flip. This allows e.g. the
implementation of the random-mass Dirac model for which localized zero-energy
(mid-gap) states exist with unsual long-range correlations.

We study the gravity dual of a thermal gauge theory whose behavior parallels
that of thermal QCD in the far IR. The UV of our theory has infinite degrees of
freedom. We holographically renormalize the supergravity action to compute the
stress tensor of the dual gauge theory with fundamental flavors incorporating
the logarithmic running of the gauge coupling. From the stress tensor we obtain
the shear viscosity and the entropy of the medium at a temperature T, and
investigate the violation of the bound for the viscosity to the entropy ratio.
This is a shortened and simplified companion paper to arXiv:0902.1540, and is
based on the talks given by M. Mia at the "Strong and Electroweak Matter 2008"
workshop and the McGill workshop on "AdS/CFT, Condensed Matter and QCD" in the
fall of 2008.

Loop Quantum Gravity is a formalism for describing the quantum mechanics of
the gravitational field based on the canonical quantization of General
Relativity. The most important result of LQG is that geometric quantities such
as area and volume are not arbitrary but are quantized in terms of a minimum
length. In this paper we investigate the effect of a minimum length in wave
propagation. We find that the minimum length, combined with the constancy of
the speed of light, induces a quantization of the energy of a gravitational
wave.

The internal dynamics of a dark matter structure may have the remarkable
property that the local temperature in the structure depends on direction. This
is parametrized by the velocity anisotropy beta which must be zero for relaxed
collisional structures, but has been shown to be non-zero in numerical
simulations of dark matter structures. Here we present a method to infer the
radial profile of the velocity anisotropy of the dark matter halo in a galaxy
cluster from X-ray observables of the intracluster gas. This non-parametric
method is based on a universal relation between the dark matter temperature and
the gas temperature which is confirmed through numerical simulations. We apply
this method to observational data and we find that beta is significantly
different from zero at intermediate radii. Thus we find a strong indication
that dark matter is effectively collisionless on the dynamical time-scale of
clusters, which implies an upper limit on the self-interaction cross-section
per unit mass sigma/m < 1 cm2/g. Our results may provide an independent way to
determine the stellar mass density in the central regions of a relaxed cluster,
as well as a test of whether a cluster is in fact relaxed.

A documentary well worth watching!
Great documentary about regional politics in the Middle East. Interviewing actual Iranians along with various foreign ministers & intelligence chiefs from US, France, UK lends more color to the complexity of the challenges here spanning religion and the influence of western concepts such as freedom, liberty, and nationalism... and the heart of it all - who will wrest control of oil production and profit participation. A fascinating watch - i highly recommend this documentary along with Blood & Oil - The Middle East in World War I documentary to get the full spectrum of issues and context behind the conflict-prone region as we know it today.

The purpose of this paper is to study finiteness conditions on injective
hulls of simple modules over Noetherian Down-Up algebras. We will show that the
Noetherian Down-Up algebras A(\alpha,\beta,\gamma) which are fully bounded are
precisely those which are module-finite over a central subalgebra. We show that
injective hulls of simple A(\alpha,\beta,\gamma)-modules are locally Artinian
provided the roots of X^2-\alpha X-\beta are distinct roots of unity or both
equal to one.

His social worker, who has borne witness to extremes of challenging environmental situations in her many years of caring for cancer patients, looked grim. “His father’s in jail. His mother is addicted to drugs and in the past has stolen his money and medications. His sister is developmentally delayed. He doesn’t have any caregivers and has been living independently for years.” She paused, giving me space to absorb this. “It’s going to be tricky for him to get through all of his therapy.”
Adolescents and young adults, which in medicine we define as ages 15 to 39, are a special population of patients with respect to the types of cancers they commonly get and the biology of those cancers. They also have distinct concerns from older or younger cancer patients, including unique issues surrounding their emerging identities, body image and autonomy. They are caught in the no-man’s land between being treated by adult oncologists, who may not be sensitive to these concerns, or by pediatric oncologists, where they may feel out of place sitting in an infusion chair receiving treatment next to a child.
I walked into my patient’s room, where he lay in his hospital bed, looking almost too fragile to be able to handle this huge mass lesion, never mind the chemotherapy I was about to propose. Slight, at five-and-a-half feet and 125 pounds, his face appeared even smaller, with a thick, black beard, oxygen tubing beneath his nose, and a snapback trucker baseball cap over his head. Tattoos covered both of his arms — a style element that my teenage children tell me is now considered normative. Another young man sat in the chair by his bed.
I discussed his diagnosis and its treatment. “The first course of chemotherapy we’ll give you in the hospital. After that, over the next few months, we’ll provide most of your care as an outpatient, meaning you’ll need to come back and forth to clinic a bunch of times.” I paused, giving him space to absorb this. “Is that something you can do?”
He nodded and gestured with his thumb toward his buddy, sitting in the chair beside him. “These guys will help me out.” He sounded confident.

Laderman discovered a scheme for computing the product of two 3x3 matrices
using only 23 multiplications in 1976. Since then, some more such schemes were
proposed, but it remains open how many there are and whether there exist
schemes with fewer than 23 multiplications. In this paper we present two
independent SAT-based methods for finding new schemes. Both methods allow
computing a few hundred new schemes individually, and many thousands when
combined. Local search SAT solvers outperform CDCL solvers consistently in this
application.

We have measured the resistivity of PrFeAsO$_{1-x}$F$_y$ samples over a wide
range of temperature in order to elucidate the role of electron-phonon
interaction on normal- and superconducting-state properties. The linear T
dependence of $\rho$ above 170 K followed by a saturationlike behavior at
higher temperature is a clear signature of strong electron-phonon coupling.
From the analysis of T dependence of $\rho$, we have estimated several
normal-state parameters useful for understanding the origin of
superconductivity in this system. Our results suggest that Fe-based
oxypnictides are phonon mediated BCS superconductors like Chevrel phases and
A15 compounds.

3D multi-object detection and tracking are crucial for traffic scene
understanding. However, the community pays less attention to these areas due to
the lack of a standardized benchmark dataset to advance the field. Moreover,
existing datasets (e.g., KITTI) do not provide sufficient data and labels to
tackle challenging scenes where highly interactive and occluded traffic
participants are present. To address the issues, we present the Honda Research
Institute 3D Dataset (H3D), a large-scale full-surround 3D multi-object
detection and tracking dataset collected using a 3D LiDAR scanner. H3D
comprises of 160 crowded and highly interactive traffic scenes with a total of
1 million labeled instances in 27,721 frames. With unique dataset size, rich
annotations, and complex scenes, H3D is gathered to stimulate research on
full-surround 3D multi-object detection and tracking. To effectively and
efficiently annotate a large-scale 3D point cloud dataset, we propose a
labeling methodology to speed up the overall annotation cycle. A standardized
benchmark is created to evaluate full-surround 3D multi-object detection and
tracking algorithms. 3D object detection and tracking algorithms are trained
and tested on H3D. Finally, sources of errors are discussed for the development
of future algorithms.

I actually worked in HR in Denali for several years and can definitely attest to the fact that locals/US nationals are given priority for seasonal jobs. Unfortunately, most of the American youth, as the article mentioned, failed to show up for work at all or did not have even close to the work ethic of the international students and were often the ones who's employment had to be terminated (drinking on the job, bad attitude, etc).

Warm, waterproof, good buy.
These are good quality pants and I can tell they are warm and definitely waterproof. My biggest concern was sizing. I ordered a large (5’6” 140lbs) and they fit just fine... I have plenty of room to wear another layer under for my trip since it’s going to be very cold. They don’t look very flattering though! But good enough for snow pants.

The purpose of this paper is to estimate the intensity of a Poisson process
$N$ by using thresholding rules. In this paper, the intensity, defined as the
derivative of the mean measure of $N$ with respect to $ndx$ where $n$ is a
fixed parameter, is assumed to be non-compactly supported. The estimator
$\tilde{f}_{n,\gamma}$ based on random thresholds is proved to achieve the same
performance as the oracle estimator up to a possible logarithmic term. Then,
minimax properties of $\tilde{f}_{n,\gamma}$ on Besov spaces ${\cal
B}^{\ensuremath \alpha}_{p,q}$ are established. Under mild assumptions, we
prove that $$\sup_{f\in B^{\ensuremath \alpha}_{p,q}\cap \ensuremath \mathbb
{L}_{\infty}} \ensuremath \mathbb {E}(\ensuremath | | \tilde{f}_{n,\gamma}-f|
|_2^2)\leq C(\frac{\log n}{n})^{\frac{\ensuremath \alpha}{\ensuremath
\alpha+{1/2}+({1/2}-\frac{1}{p})_+}}$$ and the lower bound of the minimax risk
for ${\cal B}^{\ensuremath \alpha}_{p,q}\cap \ensuremath \mathbb {L}_{\infty}$
coincides with the previous upper bound up to the logarithmic term. This new
result has two consequences. First, it establishes that the minimax rate of
Besov spaces ${\cal B}^{\ensuremath \alpha}_{p,q}$ with $p\leq 2$ when non
compactly supported functions are considered is the same as for compactly
supported functions up to a logarithmic term. When $p>2$, the rate exponent,
which depends on $p$, deteriorates when $p$ increases, which means that the
support plays a harmful role in this case. Furthermore, $\tilde{f}_{n,\gamma}$
is adaptive minimax up to a logarithmic term.

We identify and characterize low-mass stars in the ~3 Myr old Trumpler 16
(Tr16) region by means of a deep Chandra X-ray observation, and study their
optical and near-IR properties. We compare X-ray activity of Tr16 stars with
known characteristics of Orion and Cygnus OB2 stars. We analyzed a 88.4 ksec
Chandra ACIS-I observation pointed at the center of Tr16. Because of diffuse
X-ray emission, source detection was performed using the PWDetect code for two
different energy ranges: 0.5-8.0 keV and 0.9-8.0 keV. Results were merged into
a single final list. We positionally correlate X-ray sources with optical and
2MASS catalogues. Source events were extracted with the IDL-based routine
ACIS-Extract. X-ray variability was characterized using the Kolmogorov-Smirnov
test and spectra were fitted by using XSPEC. X-ray spectra of early-type,
massive stars were analyzed individually. Our list of X-ray sources consists of
1035 entries, 660 of which have near-IR counterparts and are probably
associated with Tr16 members. From near-IR color-color and color-magnitudes
diagrams we compute individual masses of stars and their Av values. About 15%
of the near-IR counterparts show disk-induced excesses. X-ray variability is
found in 77 sources. X-ray emission from OB stars appear softer than the
low-mass stars. The Tr16 region has a very rich population of low-mass X-ray
emitting stars. An important fraction of its circumstellar disks survive the
intense radiation field of its massive stars. Stars with masses 1.5-2.5 Mo
display X-ray activity similar to that of stars in Cyg OB2 but much less
intense than observed for Orion Nebula Cluster members.

I found this to be the most enjoyable Muppets movie, because I felt it was the most light-hearted and had the best comic delivery on most of its lines. The Muppets try to go on Broadway to sell an original musical they've written, but along the way, they run into the usual problems, including Kermit's memory loss here. While there aren't as many great cameos here as in the original "Muppets Movie," there are some including Joan Rivers and Dabney Coleman. Simply the timing and delivery of so many of the lines is great, and the situations the Muppets find themselves in are hilarious. The original songs are also good here, and the ending is satisfying. There is not much else to say about the film, but Muppet fans should see it for sure. It is the funniest Muppet movie and is sure to be enjoyed by all.<br /><br />***1/2 out of ****

Many theories beyond the Standard Model predict new phenomena which decay to
well isolated, high-$p_{\text{T}}$ leptons. Searches for new physics with these
signatures are performed using the ATLAS experiment at the LHC. The results
reported here use the pp collision data sample collected by the ATLAS detector
at the LHC with a center-of-mass energy of 13 TeV.

We study how to incorporate CP violation in the Froggatt--Nielsen (FN)
mechanism. To this end, we introduce non-renormalizable interactions with a
flavor democratic structure to the fermion mass generation sector. It is found
that at least two iso-singlet scalar fields with imposed a discrete symmetry
are necessary to generate CP violation due to the appearance of the relative
phase between their vacuum expectation values.
In the simplest model, ratios of quark masses and the
Cabibbo-Kobayashi-Maskawa (CKM) matrix including the CP violating phase are
determined by the CKM element |V_{us}| and the ratio of two vacuum expectation
values R=|R|e^{i*alpha} (a magnitude and a phase). It is demonstrated how the
angles phi_i (i=1--3) of the unitarity triangle and the CKM off-diagonal
elements |V_{ub}| and |V_{cb}| are predicted as a function of |V_{us}|, |R| and
\alpha. Although the predicted value of the CP violating phase does not agree
with the experimental data within the simplest model, the basic idea of our
scenario would be promising to construct a more realistic model of flavor and
CP violation.

We argue that the unscreened Coulomb interaction in graphene provides a
positive, universal, and logarithmic correction to scaling of zero-temperature
conductivity with frequency. The combined effect of the disorder due to
wrinkling of the graphene sheet and the long range electron-electron
interactions is a finite positive contribution to the dc conductivity. This
contribution is disorder strength dependent and thus non-universal. The
low-energy behavior of such a system is governed by the line of fixed points at
which both the interaction and disorder are finite, and the density of states
is exactly linear. An estimate of the typical random vector potential
representing ripples in graphene brings the theoretical value of the minimal
conductivity into the vicinity of 4e^2/h.

This paper presents an effective method for fingerprint verification based on
a data mining technique called minutiae clustering and a graph-theoretic
approach to analyze the process of fingerprint comparison to give a feature
space representation of minutiae and to produce a lower bound on the number of
detectably distinct fingerprints. The method also proving the invariance of
each individual fingerprint by using both the topological behavior of the
minutiae graph and also using a distance measure called Hausdorff distance.The
method provides a graph based index generation mechanism of fingerprint
biometric data. The self-organizing map neural network is also used for
classifying the fingerprints.

For many segmentation tasks, especially for the biomedical image, the
topological prior is vital information which is useful to exploit. The
containment/nesting is a typical inter-class geometric relationship. In the
MICCAI Brain tumor segmentation challenge, with its three hierarchically nested
classes 'whole tumor', 'tumor core', 'active tumor', the nested classes
relationship is introduced into the 3D-residual-Unet architecture. The network
comprises a context aggregation pathway and a localization pathway, which
encodes increasingly abstract representation of the input as going deeper into
the network, and then recombines these representations with shallower features
to precisely localize the interest domain via a localization path. The
nested-class-prior is combined by proposing the multi-class activation function
and its corresponding loss function. The model is trained on the training
dataset of Brats2018, and 20% of the dataset is regarded as the validation
dataset to determine parameters. When the parameters are fixed, we retrain the
model on the whole training dataset. The performance achieved on the validation
leaderboard is 86%, 77% and 72% Dice scores for the whole tumor, enhancing
tumor and tumor core classes without relying on ensembles or complicated
post-processing steps. Based on the same start-of-the-art network architecture,
the accuracy of nested-class (enhancing tumor) is reasonably improved from 69%
to 72% compared with the traditional Softmax-based method which blind to
topological prior.

High-Pitched Tone in Background
For this price, they're definitely fine. The biggest issue is that when they're connected to anything there's a small high-pitched tone that comes on and off every so often. It's a little annoying at times, but music is usually loud enough to cover it up. When the headphones are connecting/being turned on they also kind of scream "CONNECTED" or "POWER ON" in your ear a little bit.

If you want to waste a small portion of your life sit in front of this predictable zombie film. It fails at the first post by not being scary OR funny. It is a dull grey movie that I guess went straight to video. Hammy and tongue in cheek acting leave a sour taste in the mouth. If you want to watch a poor but still watchable recent zombie film watch Diary of the Dead. Poor special effects, school level script. Zombie films work if they have a moral point or even a political point . This movie has nothing, there is no worthy point that zombification underscores. This is as thrilling and convincing as a Republican Convention, no sorry watching the Republican Convention would be a better example of a Zombie movie.

We prove the homogenization to the Brinkman equations for the incompressible
Stokes equations in a bounded domain which is perforated by a random collection
of small spherical holes. The fluid satisfies a no-slip boundary condition at
the holes. The balls generating the holes have centres distributed according to
a Poisson point process and i.i.d. unbounded radii satisfying a suitable moment
condition. We stress that our assumption on the distribution of the radii does
not exclude that, with overwhelming probability, the holes contain clusters
made by many overlapping balls. We show that the formation of these clusters
has no effect on the limit Brinkman equations. Due to the incompressiblility
condition and the lack of a maximum principle for the Stokes equations, our
proof requires a very careful study of the geometry of the random holes
generated by the class of probability measures considered.

We prove an analogue of Selberg's trace formula for a delta potential on a
hyperbolic surface of finite volume. For simplicity we restrict ourselves to
surfaces with at most one cusp, but our methods can easily be extended to any
number of cusps. In the case of a noncompact surface we derive perturbative
analogues of Maass cusp forms, residual Maass forms and nonholomorphic
Eisenstein series. The latter satisfy a functional equation as in the classical
case. We also introduce a perturbative analogue of Selberg's zeta function and
apply the trace formula to prove its meromorphic continuation to the complex
plane as well as a functional equation.

BackgroundArtificial intelligence (AI) analytics have not been applied to global burden of disease (GBD) risk factor data to study population health. The comparative risk assessment (CRA) systematic literature review-based methodology for population attributable fractions (PAFs in percents) calculations has not been utilised for quantifying dietary and other risk factors for body mass index kg/M2 (BMI).
MethodsInstitute of Health Metrics and Evaluation (IHME) staff and volunteer collaborators analysed over 12,000 GBD risk factor surveys of people from 195 countries and synthesized the data into representative mean cohort BMI and risk factor values. We formatted IHME GBD data relevant to BMI and associated risk factors. We empirically explored the univariate and multiple regression correlations of BMI risk factors with worldwide BMI to derive a BMI multiple regression formula (BMI formula). Main outcome measures included the performances of the BMI formula when tested with all nine Bradford Hill causality criteria each scored on a 0-5 scale: 0=negative to 5=very strong support.
FindingsThe BMI formula derived, with all foods in kilocalories/day (kcal/day), BMI formula risk factor coefficients were adjusted to equate with their PAFs. BMI increasing foods had "+" signs and BMI decreasing foods "-" signs. Total BMI formula PAF=80.96%. BMI formula=(0.37%*processed meat + 4.23%*red meat + 0.02%*fish + 2.24%*milk + 5.67%*poultry + 1.77%*eggs + 0.34%*alcohol + 0.99%*sugary beverages + 0.04%*corn + 0.72%*potatoes + 8.48%*saturated fatty acids + 3.89%*polyunsaturated fatty acids + 0.27%*trans fatty acids - 2.99%*fruit - 4.07%*vegetables - 0.37%*nuts and seeds - 0.45%*whole grains - 1.49%*legumes - 8.62%*rice - 0.10%*sweet potatoes - 7.45% physical activity (METs/week) - 20.38%*child underweight + 6.02%*sex (male=1, female=2))*0.05012 + 21.77. BMI formula versus BMI: r=0.907, 95% CI: 0.903 to 0.911, p<0.0001. Bradford Hill causality criteria test scores (0-5): (1) strength=5, (2) experimentation=5, (3) consistency=5, (4) dose-response=5, (5) temporality=5, (6) analogy=4, (7), plausibility=5, (8) specificity=5, and (9) coherence=5. Total score=44/45.
InterpretationNine Bradford Hill causality criteria strongly supported a causal relationship between the BMI formula derived and mean BMIs of worldwide cohorts. The artificial intelligence methodology introduced could inform individual, clinical, and public health strategies regarding overweight/obesity prevention/treatment and other health outcomes.

Research in contextO_ST_ABSEvidence before this studyC_ST_ABSComparative risk assessment (CRA) systematic literature review-based methodology has been used in worldwide global burden of disease (GBD) analysis to determine population attributable fraction(s) (PAF(s)) for one or more risk factors for various health outcomes. So far, CRA has not been applied to derive PAFs for dietary and other risk factors for worldwide BMI. Artificial intelligence (AI) analytics has not yet been applied to worldwide GBD data as an alternative to the CRA methodology for determining risk factor PAFs for health outcomes.
Added value of this study{square}A multiple regression derived BMI formula (BMI formula) including PAFs of 20 dietary risk factors, physical activity, childhood severe underweight, and sex satisfied all nine Bradford Hill causality criteria. The BMI formula also plausibly predicted the long-term BMI outcomes related to various dietary and physical activity scenarios. All the BMI formulas 24 risk factor PAFs were consistent in sign (+ or -) with the preponderance of previously published studies on those risk factors related to BMI.
Implications of all the available evidenceThe AI analytics methodology of GBD data modeling of BMI and associated risk factors infers causality of the BMI formula estimates with BMI worldwide and BMIs of subsets. This methodology may enable multiple regression formulas for risk factors of health outcomes for a range of non-communicable diseases--testable by Bradford Hill causality criteria.

The state is down to three commercial refineries after Flint Hills’ North Pole refinery ceased operations in 2014: Petro Star’s refineries in Fairbanks and Valdez and Tesoro’s refinery in Nikiski. Petro Star mostly produces jet fuel while the Tesoro refinery mostly produces gasoline and exports the remaining heavy oil to other markets.

New very precise KLOE data on $\m{e}^+\m{e}^-\to\pi^+\pi^-$ obtained by
radiative return method in Frascati are unified with corrected CMD-2 and SND
Novosibirsk $\m{e}^+\m{e}^-\to\pi^+\pi^-$ data and supplemented below and
beyond by older data in order to be described by the unitary and analytic pion
electromagnetic form factor model, which provides the most precise neutral
$\rho$-meson family parameters.
Then the recently appeared accurate Belle (KEK) data of the weak pion form
factor are described by the same unitary and analytic model, as it follows from
the CVC hypothesis, providing the charged $\rho$-meson family parameters. As a
result the most reliable parameter differences of the $\rho$-meson family are
determined.

I get the feeling that Lisa Krueger is easy to overlook. I personally found her first film, 1996's Manny and Lo, to be a wonderfully detailed character study and the performances were uniformly wonderful(with special credit to Mary Kay Place). The film played for a week or two in major urban centers and vanished. One or two critics really liked it, but many viewed it as slight. Krueger's second film, Committed, was released this year (2000) (after nearly two years of delays) and it similarly vanished. And once again critics dismissed the film as slight and pushed the film aside, at most praising Heather Graham's screen presence, but rarely her acting ability. And once again, for me, Committed is a solid success. I feel as if Krueger has a genuine voice and a personal visual style and these are traits that shouldn't be so easily ignored, simply because she works on a very restrained canvass.<br /><br />The title has several meanings, but mostly it refers to Joline (Graham)'s refusal to let her husband Carl (Luke Wilson) flake out and leave her. She follows him from New York to El Paso and becomes one of the most appealing stalkers in recent cinematic history. Her respect for her marriage vows leads her to Mexican mysticism and self-discovery. And yep, the plot is just that simple and thus, just that easy to ignore.<br /><br />Joline, of course, is the crying voice of a generation whose parents divorced at a rate nearing fifty percent. And for me, her personal revolution against broken promises and a legacy of deceit is fairly intelligent and powerful. Confident in the belief that people just don't have enough faith in each other, Joline inevitably has to discover that her beliefs aren't in synche with those of society at large. Several comments her have referred to her character as one-dimensional and I'm afraid that that's a simplistic reading of the film. Or perhaps even a misreading. If Joline were just an innocent, she wouldn't be interesting at all. It's the fact that she understands the world and refuses to play by the rules of the "normals" that makes her so interesting. Sociologically, she's a complete deviant.<br /><br />Krueger sometimes falls into moments of cutesy dialogue and her direction of this film has a rather odd over-reliance on shots of clouds moving across the El Paso skyline. However, her mistakes are fairly rare and in this film, as in Manny and Lo, it's the performances that carry the day. Graham has never been better because she's never had a character as perfectly tailored to her as Joline. For the first time in her career, Graham seems comfortable playing an adult, even one in slightly arrested development. She carries the film perfectly. Luke Wilson and Casey Affleck (as Joline's brother) both have a number of fine moments, as do Alfonso Arau, as a Mexican Mystic and Mark Ruffalo and T-Bo, the slightly psychotic truck driver. As in Manny and Lo, the characters are part of their environments, well detailed totally organic creations. These characters may sometimes seem pointlessly quirky, but they make sense in their context. Even Goran Visnjic, as an artist turned on by Joline's devotion, fits in in some strange way, even though his character's foreigness is never discussed.<br /><br />For me, this is a movie that gains depth looking back. Another commenter here spoke of the stereotypical Mexican portrayals. And again I'm tempted to call that a misreading. Joline is looking for self-justification. She knows that her commitment is out of control, but she's looking for any spiritual avenue that can help her make sense of herself. Arau's character understands that most people don't believe in him and he plays up his own faith when he sees a woman who respects him. <br /><br />I guess I can understand how this movie could be viewed as underwhelming, I'd simply disagree. It's consistently funny, frequently hilarious, and all of the characters exude a warmth which is quite wonderful.<br /><br />I'm giving this one a 7.5/10 and when I log in the vote here, that'll go up to an 8.

Artificial neural network has achieved unprecedented success in the medical
domain. This success depends on the availability of massive and representative
datasets. However, data collection is often prevented by privacy concerns and
people want to take control over their sensitive information during both
training and using processes. To address this problem, we propose a
privacy-preserving method for the distributed system, Stochastic Channel-Based
Federated Learning (SCBF), which enables the participants to train a
high-performance model cooperatively without sharing their inputs.
Specifically, we design, implement and evaluate a channel-based update
algorithm for the central server in a distributed system, which selects the
channels with regard to the most active features in a training loop and uploads
them as learned information from local datasets. A pruning process is applied
to the algorithm based on the validation set, which serves as a model
accelerator. In the experiment, our model presents better performances and
higher saturating speed than the Federated Averaging method which reveals all
the parameters of local models to the server when updating. We also demonstrate
that the saturating rate of performance could be promoted by introducing a
pruning process. And further improvement could be achieved by tuning the
pruning rate. Our experiment shows that 57% of the time is saved by the pruning
process with only a reduction of 0.0047 in AUCROC performance and a reduction
of 0.0068 in AUCPR.

In cellular systems using frequency division duplex, growing Internet
services cause unbalance of uplink and downlink traffic, resulting in poor
uplink spectrum utilization. Addressing this issue, this paper considers
overlaying an ad hoc network onto a cellular uplink network for improving
spectrum utilization and spatial reuse efficiency. Transmission capacities of
the overlaid networks are analyzed, which are defined as the maximum densities
of the ad hoc nodes and mobile users under an outage constraint. Using tools
from stochastic geometry, the capacity tradeoff curves for the overlaid
networks are shown to be linear. Deploying overlaid networks based on frequency
separation is proved to achieve higher network capacities than that based on
spatial separation. Furthermore, spatial diversity is shown to enhance network
capacities.

Worked great after spay!
I was looking for an alternative to the e-collar to use after my 2 girls were spayed and these worked great! The fabric did not stick to their wounds or snag on their stitches and they seemed to be very comfortable wearing them. We loved the easy access for potty time. I would not recommend leaving your pet alone after surgery wearing just this suit; however, if you plan to be with your pet during their recovery period - this suit makes everyone happier!

I have to agree with MR. Caruso Jr Lanza,s was the finest voice god had to offer if only he could have found the courage to go for broke leave Hollywood and head for the opera he could have been the American Caruso everyone says he could have been but in any case he is a fantastic introduction to the art form no bones about it and if thats the way its gonna be so be it. see the film you'll see why Mr Lanza still come up in discussion even in my house. Someone says Pavarotti i say MARIO LANZA.As for the film itself when will it be on DVD they must have it restored and VHS isn't good enough but this should also be the only Lanza film put on DVD the others are down right bad and boring .

In the density distribution of a deformed target-nucleus, the spherical
$\lambda = 0$ and the deformed $\lambda = 2$ parts were considered. On this
basis, the corresponding potential parts $U_0$ and $U^{(2)}_{int}$ of a double
-folding microscopic nucleus-nucleus optical potential are obtained. Then, for
these potentials and by using the coupled-channel technique (ECIS), the elastic
and inelastic amplitudes are calculated for $^{17}O$ heavy ion scattering on
$2^{+}$ collective excited state of various target nuclei. Besides, the same
cross-sections are calculated in the frame of an adiabatic approach of the
eikonal approximation, where the inelastic amplitude is the linear function of
$U^{(2)}_{int}$. Both the obtained results are compared with the experimental
data, and also discuss their efficiency in predicting the deformation
parameters of nuclei.

We study the system \begin{align*} \label{prob:star} \tag{$\star$}
\begin{cases}
u_t = \Delta u - \nabla \cdot (u \nabla v) - u - f(u) w + \kappa, \\
v_t = \Delta v - v + f(u) w, \\
w_t = \Delta w - w + v,
\end{cases} \end{align*} which models the virus dynamics in an early stage of
an HIV infection, in a smooth, bounded domain $\Omega \subset \mathbb R^n, n
\in \mathbb N,$ for a parameter $\kappa \ge 0$ and a given function $f \in
C^1([0, \infty))$ satisfying $f \ge 0$, $f(0) = 0$ and $f(s) \le K_f s^\alpha$
for all $s \ge 1$, some $K_f \gt 0$ and $\alpha \in \mathbb R$.
We prove that whenever \begin{align*}
\alpha \lt \frac2n, \end{align*} solutions to \eqref{prob:star} exist
globally and are bounded. The proof mainly relies on smoothing estimates for
the Neumann heat semigroup and (in the case $\alpha \gt 1$) on a functional
inequality.
Furthermore, we provide some indication why the exponent $\frac2n$ could be
essentially optimal.

We investigate the infinite-dimensional two-orbital Hubbard model at
arbitrary band fillings. By means of the self-energy functional approach, we
discuss the stability of the metallic state in the systems with same and
different bandwidths. It is found that the Mott insulating phases are realized
at commensurate band fillings. Furthermore, it is clarified that the orbital
selective Mott phase with one orbital localized and the other itinerant is
stabilized even at fractional band fillings in the system with different
bandwidths.

Under natural hypotheses we give an upper bound on the dimension of families
of singular curves with hyperelliptic normalizations on a surface S with p_g(S)
>0 via the study of the associated families of rational curves in Hilb^2(S).
We use this result to prove the existence of nodal curves of geometric genus
3 with hyperelliptic normalizations, on a general K3 surface, thus obtaining
specific 2-dimensional families of rational curves in its Hilbert square. We
describe two infinite series of examples of general, primitively polarized K3's
such that their Hilbert squares contain a IP^2 or a threefold birational to a
IP^1-bundle over a K3.
We discuss some consequences on the Mori cone of the Hilbert square of a
general K3.

Posted By TheNewsCommenter: From Techhive.com: “Kleverness Smart Lighting review: This hub-based lighting system is unfinished and expensive”. Below is an excerpt from the article.
Kleverness proudly bills its products as “the best, easiest and smartest solution for your home’s lighting.” I can categorically tell you that none of those claims are accurate, and that today Kleverness is not worth serious consideration if you want to outfit your home with smart lights.
The hockey puck-sized Klever Hub requires just the ethernet hookup and a power connection, and then you’re ready to connect via the Kleverness app to get things going. Or so I thought. After registering your name, email address, and a password with the app, you must wait for a confirmation code to be delivered via email before you can proceed. I registered and waited… and waited… and it wasn’t until nearly an hour later that my confirmation code finally arrived, after which time I had already created a new account with a different email address. This time the code landed in a spam folder, another aggravation.
The next step in setup is to scan a QR code on the underside of the Hub to register it to the app. I scanned, and the connection failed. I tried twice again, same result. After unplugging the Hub and plugging it back in, I tried a fourth time. The app crashed. The fifth try turned out to be the charm.
After a lengthy firmware update, I was finally ready to get started adding Kleverness components. Marketed as a smart lighting solution, Kleverness does not sell light bulbs. Instead, it sells an in-wall switch, an in-wall dimmer, and a plug-in outlet. The system’s goal is not to give you tunable lighting options but rather a way to control the lights you already have. Note that all this gear requires the Klever Hub to work.
It may come as no surprise to hear that the Kleverness app crashed over and over again when I was setting up these devices (more QR codes to be scanned), requiring multiple force-quits of the app and power cycling the Hub before I finally got anything to work. All told, I spent 2.5 hours working with the Kleverness system to get just one plug-in outlet working.

Witten's conjecture suggests that the polynomial invariants of Donaldson are
expressible in terms of the Seiberg-Witten invariants if the underlying
four-manifold is of simple type. A higher rank version of the Donaldson
invariants was introduced by Kronheimer. Before even having been defined, the
physicists Mari\~no and Moore had already suggested that there should be a
generalisation of Witten's conjecture to this type of invariants. We study a
generalisation of the classical cobordism program to the higher rank situation
and obtain vanishing results which gives evidence that the generalisation of
Witten's conjecture should hold.

Geographic space is better understood through the topological relationship of
the underlying streets (note: entire streets rather than street segments),
which enables us to see scaling or fractal or living structure of far more
less-connected streets than well-connected ones. It is this underlying scaling
structure that makes human activities predictable, albeit in the sense of
collective rather than individual human moving behavior. This topological
analysis has not yet received its deserved attention in the literature, as many
researchers continue to rely on segment analysis for predicting human
activities. The segment-analysis-based methods are essentially geometric, with
a focus on geometric details of locations, lengths, and directions, and are
unable to reveal the scaling property, which means they cannot be used for
human activities prediction. We conducted a series of case studies using London
streets and tweet location data, based on related concepts such as natural
streets, and natural street segments (or street segments for short), axial
lines, and axial line segments (or line segments for short). We found that
natural streets are the best representation in terms of human activities or
traffic prediction, followed by axial lines, and that neither street segments
nor line segments bear a good correlation between network parameters and tweet
locations. These findings point to the fact that the reason why axial
lines-based space syntax, or the kind of topological analysis in general, works
has little to do with individual human travel behavior or ways that human
conceptualize distances or spaces. Instead, it is the underlying scaling
hierarchy of streets - numerous least-connected, a very few most-connected, and
some in between the least- and most-connected - that makes human activities
predictable.

Color Bleed
Overall, nice fabric. Beautiful color. I am 5'9 with a 34" inseam and it was perfect with a pair of flats. I wear a medium and I ordered a large (unsure of sizing) and I could have went with the normal medium, no need for sizing up. It felt great and soft. Now to the reason for the 2 rating...I always check for color fastness prior to including new clothing into the laundry; and it is a good thing I did, I washed and washed by hand (which seemed like forever) - and the color was constantly bleeding, after about the 5th application of soap my husband said, "Through it in the trash", it is not worth it, and reluctantly so I did. Although, I was going to wash this in the machine, it would have been a HUGE mistake. I am very displeased with the product for this reason only. I ordered the "Wine Red", so I can not speak about color bleed in other colors; however, I would caution you to conduct a test for color bleeding prior to potentially damaging an entire load of clothes.

Surprisingly happy
Had a glitch in shipping but thats just FedEx for ya. After reading reviews AFTER i bought it i was concerned but once it arrived we put it together and i must say im pretty happy with it. Its the PERFECT size and quality for an inside hutch for our daughters bunny. Some reviews say the wholes arent pre drilled, i easily took a screw driver through the areas i needed to by hand. The only thing i am sorta concerned about is the bottom pull out part i feel it could be made with better material considering thats the part that will grt "soiled" the most. Other than that for $50 i dig it 😄

The concept of operator residuation for bounded posets with unary operation
was introduced by the first two authors. It turns out that in some cases when
these operators are transformed into lattice terms and the poset ${\mathbf P}$
is completed into a Dedekind-MacNeille completion $\BDM(\mathbf P)$ then the
complete lattice $\BDM(\mathbf P)$ becomes a residuated lattice with respect to
these transformed terms. It is shown that this holds in particular for Boolean
posets and for relatively pseudocomplemented posets.
More complicated situation is with orthomodular and pseudo-orthomodular
posets. We show which operators $M$ (multiplication) and $R$ (residuation)
yield operator left-residuation in a pseudo-orthomodular poset ${\mathbf P}$
and if $\BDM(\mathbf P)$ is an orthomodular lattice then the transformed
lattice terms $\odot$ and $\to$ form a left residuation in $\BDM(\mathbf P)$.
However, it is a problem to determine when $\BDM(\mathbf P)$ is an orthomodular
lattice. We get some classes of pseudo-orthomodular posets for which their
Dedekind-MacNeille completion is an orthomodular lattice and we introduce the
so called strongly $D$-continuous pseudo-orthomodular posets. Finally we prove
that,for a pseudo-orthomodular poset ${\mathbf P}$, the Dedekind-MacNeille
completion $\BDM(\mathbf P)$ is an orthomodular lattice if and only if
${\mathbf P}$ is strongly $D$-continuous.

Amazon stuck it to me on Rental
I rented this to teach a world history class with it. It was a used copy, heavily highlighted and the binding was broken when I received it. I used it for a semester and the binding broke some more. They are charging me an additional $61 (the balance of the price for a new book???) and sending it back to me. I WILL NEVER USE AMAZON RENTAL AGAIN OR RECOMMEND IT TO STUDENTS. Am also considering never doing any more business with Amazon.

matrices, for the suspension in the triangulated category of non-commutative
motives. As a consequence, this simple model holds in all the classical
invariants such as Hochschild homology, cyclic homology and its variants
(periodic, negative, ...), algebraic K-theory, topological Hochschild homology,

All dogs go to Heaven is one of the best movies I've ever seen. I first saw it when I was like 3. Now I'm 12 and I rented it, it makes me think of things and it brings back so many memories, those were "the days". I love the music, I love when Charlie is arriving in Heaven, I love the song "Let me be surprised". I love how Charlie looks and his voice, Bert Reynolds could only play Charlie's voice this great. I love this movie, the 1st one is the best one because it's so original and great. It really does bring back memories that no one can describe, not even me. If only I could go back to those days. I love the characters. If this is the way the memories come back when I'm 12 imagine how I'll feel when I'm like 19, I hope I'll be able to watch this when I'm older. When I first seen this I never knew that I would really look back on it and feel this way , I hope it will be available to watch. I'm so happy that this movie was made and the amazing idea came to mind and heart. On a scale from 1-10 I'd give it a perfect 10. It's an amazing movie. It's so hard to explain the feeling, when I get older and if I have kids, I hope they can experience this feeling.

Because the choice and tuning of the optimizer affects the speed, and
ultimately the performance of deep learning, there is significant past and
recent research in this area. Yet, perhaps surprisingly, there is no generally
agreed-upon protocol for the quantitative and reproducible evaluation of
optimization strategies for deep learning. We suggest routines and benchmarks
for stochastic optimization, with special focus on the unique aspects of deep
learning, such as stochasticity, tunability and generalization. As the primary
contribution, we present DeepOBS, a Python package of deep learning
optimization benchmarks. The package addresses key challenges in the
quantitative assessment of stochastic optimizers, and automates most steps of
benchmarking. The library includes a wide and extensible set of ready-to-use
realistic optimization problems, such as training Residual Networks for image
classification on ImageNet or character-level language prediction models, as
well as popular classics like MNIST and CIFAR-10. The package also provides
realistic baseline results for the most popular optimizers on these test
problems, ensuring a fair comparison to the competition when benchmarking new
optimizers, and without having to run costly experiments. It comes with output
back-ends that directly produce LaTeX code for inclusion in academic
publications. It supports TensorFlow and is available open source.

We first present a warped product manifold with boundary to show the
non-uniqueness of the positive constant scalar curvature and positive constant
boundary mean curvature equation. Next, we construct a smooth counterexample to
show that the compactness of the set of "lower energy" solutions to the above
equation fails when the dimension of the manifold is not less than $62$.

After reading the book, I loved the story. Watching the movie I was disappointed that so many changes were made. It is understandable that books and movies differ but it was two different stories, only the names and some of the book's story remained. Read the book and you'll have a better understanding of the movie. The book gives you a better development of the characters. These characters are extremely interesting and make you care about them. The locations were indeed in line with the book's descriptions. Some characters not included. Television has microwaved so many great books and stories, this is a perfect example of that. Input from the author doesn't always insure a good movie but it can help sometimes.

Parasites and pathogens vary strikingly in their virulence and the resulting selection they impose on their hosts. While the evolution of different virulence levels is well studied, the evolution of host resistance in response to different virulence levels is less understood and as of now mainly based on observations and theoretical predictions with few experimental tests. Increased virulence can increase selection for host resistance evolution if resistance costs are outweighed by the benefits of avoiding infection. To test this, we experimentally evolved the bacterium Vibrio alginolyticus in the presence of two variants of the filamentous phage, VALG{Phi}8, that differ in their virulence. The bacterial host exhibited two alternative defence strategies against future phage infection: (1) super infection exclusion (SIE) whereby phage-infected cells were immune to subsequent infection at a cost of reduced growth, and (2) surface receptor mutations (SRM) in genes encoding the MSHA type-IV pilus providing resistance to infection by preventing phage attachment. While SIE emerged rapidly against both phages, SRM evolved faster against the high virulence compared to the low virulence phage. Using a mathematical model of our system we show that increasing virulence strengthens selection for SRM due to the higher costs of infection suffered by SIE immune hosts. In both the experiments and the model, higher levels of SRM in the host population drove more rapid phage extinction. Thus, by accelerating the evolution of host resistance, more virulent phages caused shorter epidemics.

The cross section of the $\mu^+\mu^-$ pair production in $pp$-collisions at
the LHC is calculated with acount of the $Z'$ boson induced by the minimal four
color quark-lepton symmetry($MQLS$). The $\mu^+\mu^-$ invariant mass spectrum
with account of the $MQLS$ $Z'$ boson is analysed in dependence on the $Z'$
mass. The mass region for the $MQLS$ $Z'$ boson observable at the LHC is found
in dependence on the significance and on the integrated luminosity.

A 17-year-old high school football star was struck and killed by a train early Monday in Deerfield Beach.
A freight train struck a pedestrian at around 4:06 a.m. in the area of Southeast Fourth Avenue and Southeast 10th Street, according to the Broward Sheriff's Office.
The pedestrian was taken to Broward Health North, where he died, BSO said. He was later identified as Bryce Gowdy.
Gowdy was a wide receiver and a defensive back at Deerfield Beach High School. He had just signed with Georgia Tech two weeks ago.
"We are heartbroken," Georgia Tech's head coach Goeff Collins tweeted Monday afternoon along with a statement on Gowdy's death. "Bryce will always be a part of our Georgia Tech football family. We will be praying for him and all those who love him. #BelieveIn7 #RIPSimba"

That is a rough description of what Kevin Phillips later called the emerging Republican the crowd whose voting habits were molded by the act of detesting the likes of Bobby Kennedy--politicians who never worked a day in their lives, who were eager (so the perception went) to oppress the plain folk with burdensome taxes in order to fatten the undeserving poor, eager to sell out America's military supremacy out of some guilt-ridden moralism.

In this work, a fast Bilateral Solver for Quality Estimation Based
multi-focus Image Fusion method (BS-QEBIF) is proposed. The all-in-focus image
is generated by pixel-wise summing up the multi-focus source images with their
focus-levels maps as weights. Since the visual quality of an image patch is
highly correlated with its focus level, the focus-level maps are preliminarily
obtained based on visual quality scores, as pre-estimations. However, the
pre-estimations are not ideal. Thus the fast bilateral solver is then adopted
to smooth the pre-estimations, and edges in the multi-focus source images can
be preserved simultaneously. The edge-preserving smoothed results are utilized
as final focus-level maps. Moreover, this work provides a confidence-map
solution for the unstable fusion in the focus-level-changed boundary regions.
Experiments were conducted on $25$ pairs of source images. The proposed
BS-QEBIF outperforms the other $13$ fusion methods objectively and
subjectively. The all-in-focus image produced by the proposed method can well
maintain the details in the multi-focus source images and does not suffer from
any residual errors. Experimental results show that BS-QEBIF can handle the
focus-level-changed boundary regions without any blocking, ringing and blurring
artifacts.

Longitudinal phase space analyses as introduced by van Hove provided a
simplified method of separating different reaction production mechanisms. Cuts
in the longitudinal phase space can help to select specific reaction kinematics
but also induce nonflat acceptance effects in angular distributions. We show
that in photoproduction reactions dominated by t-channel exchanges, selection
of meson or baryon production over a large mass range can be optimized through
calculating mass-dependent cut limits compared to cuts on a van Hove plot
sector alone. A cut is presented that improves this selection of one type of
hadron production by rejecting another. In addition we demonstrate that using
cuts in longitudinal phase space preserves sufficient information to reliably
extract observables from the angular distribution of the final state particles.

Given a graph $G$, we consider the model where $G$ is given a random
orientation by giving each edge a random direction. It is proven that for
$a,b,s\in V(G)$, the events $\{s\to a\}$ and $\{s\to b\}$ are positively
correlated. This correlation persists, perhaps unexpectedly, also if we first
condition on $\{s\nto t\}$ for any vertex $t\neq s$. With this conditioning it
is also true that $\{s\to b\}$ and $\{a\to t\}$ are negatively correlated.
A concept of increasing events in random orientations is defined and a
general inequality corresponding to Harris inequality is given.
The results are obtained by combining a very useful lemma by Colin McDiarmid
which relates random orientations with edge percolation, with results by van
den Berg, H\"aggstr\"om, Kahn on correlation inequalities for edge percolation.
The results are true also for another model of randomly directed graphs.

Observation by the CANGAROO-III stereoscopic system of the Imaging Cherenkov
Telescope has detected extended emission of TeV gamma rays in the vicinity of
the pulsar PSR B1706$-$44. The strength of the signal observed as
gamma-ray-like events varies when we apply different ways of emulating
background events. The reason for such uncertainties is argued in relevance to
gamma-rays embedded in the "off-source data", that is, unknown sources and
diffuse emission in the Galactic plane, namely, the existence of a complex
structure of TeV gamma-ray emission around PSR B1706$-$44.

Hadron correlations in jets, ridges and opposite dijets at all $p_T$ above 2
GeV/c are discussed. Since abundant data are available from RHIC at
intermediate $p_T$, a reliable hadronization scheme at that $p_T$ range is
necessary in order to relate the semihard partonic processes to the
observables. The recombination model is therefore first reviewed for that
purpose. Final-state interaction is shown to be important for the Cronin
effect, large B/M ratio and forward production. The effect of semihard partons
on the medium is then discussed with particular emphasis on the formation of
ridge with or without trigger. Azimuthal anisotropy can result from ridges
without early thermalization. Dynamical path length distribution is derived for
any centrality. Dihadron correlations in jets on the same or opposite side are
shown to reveal detail properties of trigger and antitrigger biases with the
inference that tangential jets dominate the dijets accessible to observation.

Toward the understanding of incommensurate $\Gamma_3$ quadrupole ordering in
PrPb$_3$, we develop a microscopic theory of multipole ordering in
$f^2$-electron systems from an itinerant picture on the basis of a $j$-$j$
coupling scheme. For this purpose, we introduce the $\Gamma_7$-$\Gamma_8$
Hubbard model on a simple cubic lattice with the effective interactions that
induce local $\Gamma_3$ states. By evaluating multipole susceptibility in a
random phase approximation, we find that the hybridization between $\Gamma_7$
and $\Gamma_8$ orbitals plays a key role in the emergence of $\Gamma_3$
quadrupole ordering. We also emphasize that $\Gamma_3$ quadrupole ordering can
be understood from the concept of {\it multipole nesting}, in which the Fermi
surface region with large $\Gamma_8$ orbital density should be nested on the
area with a significant $\Gamma_7$ component when the positions of the Fermi
surfaces are shifted by the ordering vector. This concept cab be intuitively
understood from the fact that local $\Gamma_3$ doublets are mainly composed of
two singlets between $\Gamma_8$ and $\Gamma_7$ orbitals. Finally, we discuss
the possible relevance of the present theory to the experimental results of
PrPb$_3$ and point out some future problems in this direction of research.

Ever once in a while I run into a movie that is so embarrassingly bad I wonder why movies exist. This is one of them. This is a terrible attempt to parody The Godfather with annoying cartoon sounds, and bad dialogue. Eddie Deezen is just plain annoying as Tony, an annoying twit who upon his father, Don (William Hickey)'s request, takes over the family business. Tony, as I said, is an annoying little twit. This makes the whole movie a complete mess. The movie is terribly daffy. It's too cartoonish. The main point I'm trying to make is that you can't make a parody of an acclaimed drama like The Godfather with so much cartoonishness. It doesn't work that way. Believe it or not, you have to take a parody of a dramatic movie seriously. If you don't take it seriously, it will feel too much like a parody. The thing about doing a parody is that you can't seem too much like you're doing a parody. You have to make it seem like you're taking the movie at least a little bit seriously. It also feels like they're just mocking Woody Allen, and that's what makes this movie absolutely terrible.

We produce the first astrophysically-relevant numerical binary black hole
gravitational waveform in a higher-curvature theory of gravity beyond general
relativity. We simulate a system with parameters consistent with GW150914, the
first LIGO detection, in order-reduced dynamical Chern-Simons gravity, a theory
with motivations in string theory and loop quantum gravity. We present results
for the leading-order corrections to the merger and ringdown waveforms, as well
as the ringdown quasi-normal mode spectrum. We estimate that such corrections
may be discriminated in detections with signal to noise ratio $\gtrsim
180-240$, with the precise value depending on the dimension of the GR waveform
family used in data analysis.

The study of how diseases spread has greatly benefited from advances in
network modeling. Recently, a class of networks known as multilayer graphs has
been shown to describe more accurately many real systems, making it possible to
address more complex scenarios in epidemiology such as the interaction between
different pathogens or multiple strains of the same disease. In this work, we
study in depth a class of networks that have gone unnoticed up to now, despite
of its relevance for spreading dynamics. Specifically, we focus on directed
multilayer networks, characterized by the existence of directed links, either
within the layers or across layers. Using the generating function approach and
numerical simulations of a stochastic susceptible-infected-susceptible (SIS)
model, we calculate the epidemic threshold for these networks for different
degree distributions of the networks. Our results show that the main feature
that determines the value of the epidemic threshold is the directionality of
the links connecting different layers, regardless of the degree distribution
chosen. Our findings are of utmost interest given the ubiquitous presence of
directed multilayer networks and the widespread use of disease-like spreading
processes in a broad range of phenomena such as diffusion processes in social
and transportation systems.

You get what you pay for
I give this an 3 out of five stars because the overall design and weight of the hand piece is very nice and it’s great for traveling but as a Professional Nail tech for 10 years I think this drill is for beginners not doing a lot of acrylics per day. The knob came of second day of use and continues to come off when applying any pressure (minimal) at low speed bit tend to catch in acrylics!! Not good! I found that when you use speeds above 7 it does not do this. Also found that it tends to loose a little power at times don’t know if my cord to the hand piece is faulty? I do like that it stays charged for at least two to three days before needing another charge.Would I buy this again no I wouldn’t.

We present the generic Dijkstra shortest path algorithm: an efficient
algorithm for finding a shortest path in an optical network, both in a
wavelength-division multiplexed network, and an elastic optical network (EON).
The proposed algorithm is an enabler of real-time softwarized control of
large-scale networks, and is not limited to optical networks. The Dijkstra
algorithm is a generalization of the breadth-first search, and we generalize
the Dijkstra algorithm further to resolve the continuity and contiguity
constraints of the frequency slot units required in EONs. Specifically, we
generalize the notion of a label, change what we iterate with, and reformulate
the edge relaxation so that vertices are revisited, loops avoided, and worse
labels discarded. We also used the typical constriction during edge relaxation
to take care of the signal modulation constraints. The algorithm can be used
with various spectrum allocation policies. We motivate and discuss the
algorithm design, and provide our free, reliable, and generic implementation
using the Boost Graph Library. We carried out 85000 simulation runs for
realistic and random networks (Gabriel graphs) of 75 vertices with about a
billion shortest-path searches, and found that the proposed algorithm
outperforms considerably three other competing optimal algorithms that are
frequently used.

Concurrent synchronization is a regime where diverse groups of fully
synchronized dynamic systems stably coexist. We study global exponential
synchronization and concurrent synchronization in the context of Lagrangian
systems control. In a network constructed by adding diffusive couplings to
robot manipulators or mobile robots, a decentralized tracking control law
globally exponentially synchronizes an arbitrary number of robots, and
represents a generalization of the average consensus problem. Exact nonlinear
stability guarantees and synchronization conditions are derived by contraction
analysis. The proposed decentralized strategy is further extended to adaptive
synchronization and partial-state coupling.

An unusual object, G2, had its pericenter passage around Sgr A*, the
$4\times10^6$ M$_\odot$ supermassive black hole in the Galactic Centre, in
Summer 2014. Several research teams have reported evidence that following G2's
pericenter encounter the rate of Sgr A*'s bright X-ray flares increased
significantly. Our analysis carefully treats varying flux contamination from a
nearby magnetic neutron star and is free from complications induced by using
data from multiple X-ray observatories with different spatial resolutions. We
test the scenario of an increased bright X-ray flaring rate using a massive
dataset from the \textit{Chandra X-ray Observatory}, the only X-ray instrument
that can spatially distinguish between Sgr A* and the nearby Galactic Centre
magnetar throughout the full extended period encompassing G2's encounter with
Sgr A*. We use X-ray data from the 3 Ms observations of the \textit{Chandra}
\textit{X-ray Visionary Program} (XVP) in 2012 as well as an additional 1.5 Ms
of observations up to 2018. We use detected flares to make distributions of
flare properties. Using simulations of X-ray flares accounting for important
factors such as the different $Chandra$ instrument modes, we test the null
hypothesis on Sgr A*'s bright (or any flare category) X-ray flaring rate around
different potential change points. In contrast to previous studies, our results
are consistent with the null hypothesis; the same model parameters produce
distributions consistent with the observed ones around any plausible change
point.

The tetrablock is a domain in 3-dimensional complex space that meets
3-dimensional Euclidean space in a regular tetrahedron. It is shown to be
inhomogeneous and its automorphism group is determined. A type of Schwarz lemma
for the tetrablock is proved. The action of the automorphism group is described
in terms of a certain natural foliation of the tetrablock by complex geodesic
discs.

The dynamics of two penetrating superfluids exhibit an intriguing variety of
nonlinear effects. Using two distinguishable components of a Bose-Einstein
condensate, we investigate the counterflow of two superfluids in a narrow
channel. We present the first experimental observation of trains of dark-bright
solitons generated by the counterflow. Our observations are theoretically
interpreted by three-dimensional numerical simulations for the coupled
Gross-Pitaevskii (GP) equations and the analysis of a jump in the two
relatively flowing components' densities. Counterflow induced modulational
instability for this miscible system is identified as the central process in
the dynamics.

Fractional mechanics describes both conservative and non-conservative
systems. The fractional variational principles gained importance in studying
the fractional mechanics and several versions are proposed. In classical
mechanics the equivalent Lagrangians play an important role because they admit
the same Euler-Lagrange equations. By adding a total time derivative of a
suitable function to a given classical Lagrangian or by multiplying with a
constant the Lagrangian we obtain the same equations of motion.
In this study, the fractional discrete Lagrangians which differs by a
fractional derivative are analyzed within Riemann-Liouville fractional
derivatives.
As a consequence of applying this procedure the classical results are
reobtained as a special case. The fractional generalization of $Fa\grave{a}$ di
Bruno formula is used in order to obtain the concrete expression of the
fractional Lagrangians which differs from a given fractional Lagrangian by
adding a fractional derivative. The fractional Euler-Lagrange and Hamilton
equations corresponding to the obtained fractional Lagrangians are investigated
and two examples are analyzed in details.

Fluoroscopic imaging that captures X-ray images at video framerates is
advantageous for guiding catheter insertions by vascular surgeons and
interventional radiologists. Visualizing the dynamical movements non-invasively
allows complex surgical procedures to be performed with less trauma to the
patient. To improve surgical precision, endovascular procedures can benefit
from more accurate fluoroscopy data via calibration. This paper presents a
robust self-calibration algorithm suitable for single-plane and dual-plane
fluoroscopy. A three-dimensional (3D) target field was imaged by the
fluoroscope in a strong geometric network configuration. The unknown 3D
positions of targets and the fluoroscope pose were estimated simultaneously by
maximizing the likelihood of the Student-t probability distribution function. A
smoothed k-nearest neighbour (kNN) regression is then used to model the
deterministic component of the image reprojection error of the robust bundle
adjustment. The Maximum Likelihood Estimation step and the kNN regression step
are then repeated iteratively until convergence. Four different error modeling
schemes were compared while varying the quantity of training images. It was
found that using a smoothed kNN regression can automatically model the
systematic errors in fluoroscopy with similar accuracy as a human expert using
a small training dataset. When all training images were used, the 3D mapping
error was reduced from 0.61-0.83 mm to 0.04 mm post-calibration (94.2-95.7%
improvement), and the 2D reprojection error was reduced from 1.17-1.31 to
0.20-0.21 pixels (83.2-83.8% improvement). When using biplanar fluoroscopy, the
3D measurement accuracy of the system improved from 0.60 mm to 0.32 mm (47.2%
improvement).

Motivated by recent progresses in the holographic descriptions of the Kerr
and Reissner-Nordstr{\o}m (RN) black holes, we explore the hidden conformal
symmetry of nonextremal uplifted 5D RN black hole by studying the near horizon
wave equation of a massless scalar field propagating in this background.
Similar to the Kerr black hole case, this hidden symmetry is broken by the
periodicity of the associated angle coordinate in the background geometry, but
the results somehow testify the dual CFT description of the nonextremal RN
black holes. The duality is further supported by matching of the entropies and
absorption cross sections calculated from both CFT and gravity sides.

Recent studies have theoretically investigated the atomic excitation and
ionization induced by the dark matter (DM)-nucleus scattering, and it is found
that the suddenly recoiled atom is much more likely to excite or lose its
electrons than expected. Such phenomenon is called the "Migdal effect". In this
paper, we extend the established strategy to describe the Migdal effect in
isolated atoms to the case in semiconductors under the framework of
tight-binding (TB) approximation. Since the localized aspects of electrons are
respected in form of the Wannier functions (WFs), the extension of the existing
Migdal approach for isolated atoms is much more natural, while the extensive
nature of electrons in solids is reflected in the hopping integrals. We take
diamond target as a concrete proof of principle for the methodology, and
calculate relevant energy spectra and projected sensitivity of such diamond
detector. It turns out that our method as a preliminary attempt is practically
effective.

I watched this movie, or part of it, in hope that it would be fun to laugh at how bad it was, but it soon became clear that this was just plain silly. For one you have the worst acting EVER! The lead "actress" Birgitte Nielsen is terrible, uninspired and hardly even attractive. And she certainly do not look like the female warrior who could easily kick some veteran warrior kings butt, but she does. And whats with the feminist attitude, it's plain hypocrisy. For one her family was killed by a women, then she joins some warrior school or something so she can learn how to fight men. She then joins up with a fat servant and his child king, whose city was destroyed by Gedren. Those two characters are just plain stupid and destroys the little of atmosphere that the movie managed to create. After this i could not take any more of Nielsen painful acting, and the stupid clichés and lack of some real action.<br /><br />Schwarzenegger as Kalidor was the only part of this movie which actually made it remotely watchable. <br /><br />I liked the Conan movie, but this is pure crap!

In this work we present a simple, approximate method for analysis of the
basic dynamical and thermodynamical characteristics of Kerr-Newman black hole.
Instead of the complete dynamics of the black hole self-interaction we consider
only such stable (stationary) dynamical situations determined by condition that
black hole (outer) horizon circumference holds the integer number of the
reduced Compton wave lengths corresponding to mass spectrum of a small quantum
system (representing quant of the black hole self-interaction). Then, we show
that Kerr-Newman black hole entropy represents simply the quotient of the sum
of static part and rotation part of mass of black hole on the one hand and
ground mass of small quantum system on the other hand. Also we show that
Kerr-Newman black hole temperature represents the negative value of the
classical potential energy of gravitational interaction between a part of black
hole with reduced mass and small quantum system in the ground mass quantum
state. Finally, we suggest a bosonic great canonical distribution of the
statistical ensemble of given small quantum systems in the thermodynamical
equilibrium with (macroscopic) black hole as thermal reservoir. We suggest
that, practically, only ground mass quantum state is significantly degenerate
while all other, excited mass quantum states are non-degenerate. Kerr-Newman
black hole entropy is practically equivalent to the ground mass quantum state
degeneration. Given statistical distribution admits a rough (qualitative) but
simple modeling of Hawking radiation of the black hole too.

It has been a long-held belief that judicious resource allocation is critical
to mitigating interference, improving network efficiency, and ultimately
optimizing wireless communication performance. The traditional wisdom is to
explicitly formulate resource allocation as an optimization problem and then
exploit mathematical programming to solve the problem to a certain level of
optimality. Nonetheless, as wireless networks become increasingly diverse and
complex, e.g., in the high-mobility vehicular networks, the current design
methodologies face significant challenges and thus call for rethinking of the
traditional design philosophy. Meanwhile, deep learning, with many success
stories in various disciplines, represents a promising alternative due to its
remarkable power to leverage data for problem solving. In this paper, we
discuss the key motivations and roadblocks of using deep learning for wireless
resource allocation with application to vehicular networks. We review major
recent studies that mobilize the deep learning philosophy in wireless resource
allocation and achieve impressive results. We first discuss deep learning
assisted optimization for resource allocation. We then highlight the deep
reinforcement learning approach to address resource allocation problems that
are difficult to handle in the traditional optimization framework. We also
identify some research directions that deserve further investigation.

We report a 3D MHD simulation study of the interactions between radio
galaxies and galaxy-cluster-media shocks in which the incident shock normals
are orthogonal to the bipolar AGN jets. Before shock impact, light, supersonic
jets inflate lobes (cavities) in a static, uniform ICM. We examine three AGN
activity scenarios: 1) continued, steady jet activity; 2) jet source cycled off
coincident with shock/radio lobe impact; 3) jet activity ceased well before
shock arrival (a "radio phoenix" scenario). The simulations follow relativistic
electrons (CRe) introduced by the jets, enabling synthetic radio synchrotron
images and spectra. Such encounters can be decomposed into an abrupt shock
transition and a subsequent long term post shock wind. Shock impact disrupts
the pre-formed, low density RG cavities into two ring vortices embedded in the
post shock wind. Dynamical processes cause the vortex pair to merge as they
propagate downwind somewhat faster than the wind itself. When the AGN jets
remain active ram pressure bends the jets downwind, generating a narrow angle
tail morphology aligned with the axis of the vortex ring. The deflected jets do
not significantly alter dynamical evolution of the vortex ring. However, active
jets and their associated tails do dominate the synchrotron emission,
compromising the observability of the vortex structures. Downwind-directed
momentum concentrated by the jets impacts and alters the post-encounter shock.
In the "radio phoenix" scenario, no DSA of the fossil electron population is
required to account for the observed brightening and flattening of the spectra,
adiabatic compression effects are sufficient.

We use Young tableaux to compute the dimension of $V^r$, the
Prym-Brill-Noether locus of a folded chain of loops of any gonality. This
tropical result yields a new upper bound on the dimensions of algebraic
Prym-Brill-Noether loci. Moreover, we prove that $V^r$ is pure-dimensional and
connected in codimension $1$ when $\dim V^r \geq 1$. We then compute the first
Betti number of this locus for even gonality when the dimension is exactly $1$,
and compute the cardinality when the locus is finite and the edge lengths are
generic.

Early dark energy (EDE) that behaves like a cosmological constant at early
times (redshifts $z\gtrsim3000$) and then dilutes away like radiation or faster
at later times can solve the Hubble tension. In these models, the sound horizon
at decoupling is reduced resulting in a larger value of the Hubble parameter
$H_0$ inferred from the cosmic microwave background (CMB). We consider two
physical models for this EDE, one involving an oscillating scalar field and
another a slowly-rolling field. We perform a detailed calculation of the
evolution of perturbations in these models. A Markov Chain Monte Carlo search
of the parameter space for the EDE parameters, in conjunction with the standard
cosmological parameters, identifies regions in which $H_0$ inferred from {\it
Planck} CMB data agrees with the SH0ES local measurement. In these cosmologies,
current baryon acoustic oscillation and supernova data are described as
successfully as in \LCDM, while the fit to {\it Planck} data is slightly
improved. Future CMB and large-scale-structure surveys will further probe this
scenario.

Lattice Boltzmann Method(LBM) has achieved considerable success on simulating
complex flows. However, how to impose correct boundary conditions on the
fluid-solid interface with complex geometries is still an open question. Here
we proposed a velocity interpolation based bounce-back scheme where the ideas
of interpolated bounce-back and non-equilibrium extrapolation are combined. The
proposed scheme is validated by several well-defined benchmark cases. It is
shown that the proposed scheme offers a better accuracy at high Reynolds number
and less dependency on solids positions which may crucial in many engineering
and science applications.

One of the legacies of the {\rm Chandra} era is the discovery of AGN-inflated
X-ray cavities in virtually all cool-core clusters, with mechanical
luminosities comparable to or larger than the cluster cooling rate, suggesting
that AGN might be responsible for heating clusters. This discovery poses a new
set of questions that cannot be addressed by X-ray imaging or modeling alone:
Are AGN actually responsible for halting cooling flows? How is the AGN energy
transferred to heat? How tight is the observed balance between heating and
cooling? Using numerical simulations and a new virtual X-ray observatory tool,
we demonstrate that high-resolution, high-throughput X-ray spectroscopy can
address these questions and that the International X-ray Observatory \ixo will
have the necessary capabilities to deliver these measurements.

Reducing energy dissipation while increasing speed in computation and memory
is a long-standing challenge for spintronics research. In the last 20 years,
femtosecond lasers have emerged as a tool to control the magnetization in
specific magnetic materials at the picosecond timescale. However, the use of
ultrafast optics in integrated circuits and memories would require a major
paradigm shift. An ultrafast electrical control of the magnetization is far
preferable for integrated systems. Here we demonstrate reliable and
deterministic control of the out-of-plane magnetization of a 1 nm-thick Co
layer with single 6 ps-wide electrical pulses that induce spin-orbit torques on
the magnetization. We can monitor the ultrafast magnetization dynamics due to
the spin-orbit torques on sub-picosecond timescales, thus far accessible only
by numerical simulations. Due to the short duration of our pulses, we enter a
counter-intuitive regime of switching where heat dissipation assists the
reversal. Moreover, we estimate a low energy cost to switch the magnetization,
projecting to below 1fJ for a (20 nm)^3 cell. These experiments prove that
spintronic phenomena can be exploited on picosecond time-scales for full
magnetic control and should launch a new regime of ultrafast spin torque
studies and applications.

In this paper histograms of user ratings for movies (1,...,10) are analysed.
The evolving stabilised shapes of histograms follow the rule that all are
either double- or triple-peaked. Moreover, at most one peak can be on the
central bins 2,...,9 and the distribution in these bins looks smooth
`Gaussian-like' while changes at the extremes (1 and 10) often look abrupt. It
is shown that this is well approximated under the assumption that histograms
are confined and discretised probability density functions of L\'evy skew
alpha-stable distributions. These distributions are the only stable
distributions which could emerge due to a generalized central limit theorem
from averaging of various independent random avriables as which one can see the
initial opinions of users. Averaging is also an appropriate assumption about
the social process which underlies the process of continuous opinion formation.
Surprisingly, not the normal distribution achieves the best fit over histograms
obseved on the web, but distributions with fat tails which decay as power-laws
with exponent -(1+alpha) (alpha=4/3). The scale and skewness parameters of the
Levy skew alpha-stable distributions seem to depend on the deviation from an
average movie (with mean about 7.6). The histogram of such an average movie has
no skewness and is the most narrow one. If a movie deviates from average the
distribution gets broader and skew. The skewness pronounces the deviation. This
is used to construct a one parameter fit which gives some evidence of
universality in processes of continuous opinion dynamics about taste.

We solve the Combustion adiabat (CA) or the Chapman-Jouget adiabat equation
to study the phase transition (PT) of a neutron star (NS) to a quark star (QS).
The hadronic matter and quark matter equation of states are used to calculate
the matter velocities on either side of the shock front. The CA with the
hadronic matter as an input is solved to obtain the corresponding quark matter
values. The maximum of the quark pressure is reflected in the retracing of the
path in the CA curve. The downstream quark pressure maximum implies towards a
maximum mass limit of a phase transformed QS which is different from the
regular mass limit of an ordinary QS. Further, the characterization of
velocities suggest that the PT from NS to QS is not always feasible from the
center of the star. The possible mode of combustion in NSs is likely to be a
slow deflagration in most of the low and intermediate density range. The result
is crucial and emphasizes on the fact that PT in NSs does not always starts
from the center and sometimes a NS does not suffers a PT at all.

We study a two-parameter family of exactly solvable inflation models with
variable sound speed, and derive a corresponding exact expression for the
spectrum of curvature perturbations. We generalize this expression to the slow
roll case, and derive an approximate expression for the scalar spectral index
valid to second order in slow roll. We apply the result to the case of DBI
inflation, and show that for certain choices of slow roll parameters, the
Bunch-Davies limit (a) does not exist, or (b) is sensitive to stringy physics
in the bulk, which in principle can have observable signatures in the
primordial power spectrum.

For any module over the affine Weyl group we construct a representation of
the associated trigonometric Cherednik algebra $A(k)$ at critical level in
terms of Dunkl type operators. Under this representation the center of $A(k)$
produces quantum conserved integrals for root system generalizations of quantum
spin-particle systems on the circle with delta function interactions. This
enables us to translate the spectral problem of such a quantum spin-particle
system to questions in the representation theory of $A(k)$. We use this
approach to derive the associated Bethe ansatz equations. They are expressed in
terms of the normalized intertwiners of $A(k)$.

We study the most general triangle diagram through the Symmetries of Feynman
Integrals (SFI) approach. The SFI equation system is obtained and presented in
a simple basis. The system is solved providing a novel derivation of an
essentially known expression. We stress a description of the underlying
geometry in terms of the Distance Geometry of a tetrahedron discussed by
Davydychev-Delbourgo [1], a tetrahedron which is the dual on-shell diagram. In
addition, the singular locus is identified and the diagram's value on the
locus's two components is expressed as a linear combination of descendant
bubble diagrams. The massless triangle and the associated magic connection are
revisited.

Due to the rapid growth of the World Wide Web, resource discovery becomes an
increasing problem. As an answer to the demand for information management, a
third generation of World-Wide Web tools will evolve: information gathering and
processing agents. This paper describes WAVE (Web Analysis and Visualization
Environment), a 3D interface for World-Wide Web information visualization and
browsing. It uses the mathematical theory of concept analysis to conceptually
cluster objects, and to create a three-dimensional layout of information nodes.
So-called "conceptual scales" for attributes, such as location, title,
keywords, topic, size, or modification time, provide a formal mechanism that
automatically classifies and categorizes documents, creating a conceptual
information space. A visualization shell serves as an ergonomically sound user
interface for exploring this information space.

One of the possible mechanisms of high Tc superconductivity is Cooper pairing
with the help of bosons, which change the slope of the electronic dispersion as
observed by photoemission. Giustino et al. calculated that in the high
temperature superconductor La1.85Sr0.15CuO4 crystal lattice vibrations
(phonons) should have a negligible effect on photoemission spectra and
concluded that phonons do not play an important role. We show that the
calculations employed by Giustino et al. fail to reproduce huge influence of
electron-phonon coupling on important phonons observed in experiments. Thus one
would expect these calculations to similarly fail in explaining the role of
electron-phonon coupling for the electronic dispersion.
