this show is one of the worst shows of ALL TIME! absolutely no original jokes and they're always a year late. like in 2009 they will finally say something about Michael Vick's dogfights. all of the cast members are people who wanted to be on S.N.L but had to go to the lowest of the low, mad TV.its an hour of mad magazine jokes witch aren't funny to begin with, told by terrible John Stewart wanna bees. so if you have any problem tell me id love to hear the opinion of the 3 people who watch this show. family guy put it well "Osama bin Ladin was hiding in the one place no one would look, the cast of mad TV. There is a reason why no one watches the show.

Automating the extraction of meaningful temporal information from sequences of microscopy images represents a major challenge to characterize dynamical biological processes. So far, strong limitations in the ability to quantitatively analyze single-cell trajectories have prevented large-scale investigations to assess the dynamics of entry into replicative senescence in yeast. Here, we have developed DetecDiv, a microfluidic-based image acquisition platform combined with deep learning-based software for high-throughput single-cell division tracking. We show that DetecDiv can automatically reconstruct cellular replicative lifespans with high accuracy and performs similarly with various imaging platforms and geometries of microfluidic traps. In addition, this methodology provides comprehensive temporal cellular metrics using time-series classification and image semantic segmentation. Last, we show that this method can be further applied to automatically quantify the dynamics of cellular adaptation and the real-time cell survival upon exposure to environmental stress. Hence, this methodology provides an all-in-one toolbox for high-throughput phenotyping for cell cycle, stress response, and replicative lifespan assays.

Has some issues, but comfy
I like the chair, but here are my knocks on it. - I'm 6' 205lb (ding!) and my 2nd time to pull the leg-rest out it snapped the hard plastic housing holding the bars in on one side. - The armrest cover are not very sturdy it appears. After just a few days of scooting near my desk, the left arm rest casing tore and just kept tearing until the foam underneath began falling out in chunks and now 1/8th of my left armrest is gone. - After exiting the chair about 50% of the time when I come back to sit down, the gas cylinder will slowly decline all the way to bottom and I have to readjust the chair.

The stopping of baryons in heavy ion collisions at beam momenta of $p_{\rm
lab} = 20-160A$ GeV is lacking a quantitative description within theoretical
calculations. Heavy ion reactions at these energies are experimentally explored
at the Super Proton Synchrotron (SPS) and the Relativistic Heavy Ion Collider
(RHIC) and will be studied at future facilities such as FAIR and NICA. Since
the net baryon density is determined by the amount of stopping, this is the
pre-requisiste for any investigation of other observables related to structures
in the QCD phase diagram such as a first-order phase transition or a critical
endpoint. In this work we employ a string model for treating hadron-hadron
interactions within a hadronic transport approach (SMASH, Simulating Many
Accelerated Strongly-interacting Hadrons). Free parameters of the string
excitation and decay are tuned to match experimental measurements in elementary
proton-proton collisions, where some mismatch in the $x_F$ distribution of
protons is still present. Afterwards, the model is applied to heavy ion
collisions, where the experimentally observed change of the shape of the proton
rapidity spectrum from a single peak structure to a double peak structure with
increasing beam energy is reproduced. Heavy ion collisions provide the
opportunity to study the formation process of string fragments in terms of
formation times and reduced interaction cross-sections for pre-formed hadrons.
A good agreement with the measured rapidity spectra of protons and pions is
achieved while insights on the fragmentation process are obtained. In the
future, the presented approach can be used to create event-by-event initial
conditions for hybrid calculations.

Probably this is the best film of Clint Eastwood. Here action is minimal, but with plenty of good acting. A Yankee soldier Eastwood is wounded and taken by the female pupils and teachers of a school in the South, where he is hidden and taken care. Shortly after his recovery all ladies wanted to have fun with him, and some of them succeeded including the director of the school(Geraldine Page). Erotic scenes are coming until the ladies discovered that their "macho" was shared by several of them, so they became angry and poisoned him in a farewell dinner. Geraldine Page, although somewhat old, was able to play a very suggestive role as the director of the school, a woman with more failures than happiness in her life.

In this paper we study static spherically symmetric Einstein-Vlasov shells,
made up of equal mass particles, where the angular momentum L of particles
takes values only on a discrete finite set. We consider first the case where
there is only one value of L, and prove their existence by constructing
explicit examples. Shells with either hollow or black hole interiors have
finite thickness. Of particular interest is the thin shell limit of these
systems and we study its properties using both numerical and analytic arguments
to compare with known results. The general case of a set of values of L is also
considered and the particular case where L takes only two values is analyzed,
and compared with the corresponding thin shell limit already given in the
literature, finding good agreement in all cases.

{\it Ellsberg thought experiments} and empirical confirmation of Ellsberg
preferences pose serious challenges to {\it subjective expected utility theory}
(SEUT). We have recently elaborated a quantum-theoretic framework for human
decisions under uncertainty which satisfactorily copes with the Ellsberg
paradox and other puzzles of SEUT. We apply here the quantum-theoretic
framework to the {\it Ellsberg two-urn example}, showing that the paradox can
be explained by assuming a state change of the conceptual entity that is the
object of the decision ({\it decision-making}, or {\it DM}, {\it entity}) and
representing subjective probabilities by quantum probabilities. We also model
the empirical data we collected in a DM test on human participants within the
theoretic framework above. The obtained results are relevant, as they provide a
line to model real life, e.g., financial and medical, decisions that show the
same empirical patterns as the two-urn experiment.

Perfect for updos and braids!
I'm in cosmetology school, so I use this to practice sometimes. It is perfect for practicing braids, styles, cuts, or updos! I have not tried any blow drying, washing, or heat on it as I don't want to ruin it. It is good for certain things, however, the hair falls out very easily- BUT- there is a lot of it, so I would buy again.

Text summarization can be classified into two approaches: extraction and
abstraction. This paper focuses on extraction approach. The goal of text
summarization based on extraction approach is sentence selection. One of the
methods to obtain the suitable sentences is to assign some numerical measure of
a sentence for the summary called sentence weighting and then select the best
ones. The first step in summarization by extraction is the identification of
important features. In our experiment, we used 125 test documents in DUC2002
data set. Each document is prepared by preprocessing process: sentence
segmentation, tokenization, removing stop word, and word stemming. Then, we use
8 important features and calculate their score for each sentence. We propose
text summarization based on fuzzy logic to improve the quality of the summary
created by the general statistic method. We compare our results with the
baseline summarizer and Microsoft Word 2007 summarizers. The results show that
the best average precision, recall, and f-measure for the summaries were
obtained by fuzzy method.

Current flicker mitigation (or DC-balance) solutions based on run-length
limited (RLL) decoding algorithms are high in complexity, suffer from reduced
code rates, or are limited in application to hard-decoding forward error
correction (FEC) decoders. Fortunately, non-RLL DC-balance solutions can
overcome the drawbacks of RLL-based algorithms, but they meet some difficulties
in system latency, low code rate or inferior error-correction performance.
Recently, non-RLL flicker mitigation solution based on Polar code has proved to
be a most optimal approach due to its natural equal probabilities of short runs
of 1's and 0's with high error-correction performance. However, we found that
this solution can only maintain DC balance only when the data frame length is
sufficiently long. Therefore, these solutions are not suitable for using in
beacon-based visible light communication (VLC) systems, which usually transmit
ID information in small-size data frames. In this paper, we introduce a flicker
mitigation solution designed for beacon-based VLC systems that combines a
simple pre-scrambler with a (256;158) non-systematic polar encoder.

Well that's kind of the point of the designation of sainthood. And the point of the Catholic Church as a whole. It sounds absurd, St. Paul told us as much himself. But I believe it anyhow.

The alternating direction method of multipliers (ADMM) were extensively
investigated in the past decades for solving separable convex optimization
problems. Fewer researchers focused on exploring its convergence properties for
the nonconvex case although it performed surprisingly efficient. In this paper,
we propose a symmetric ADMM based on different acceleration techniques for a
family of potentially nonsmooth nonconvex programing problems with equality
constraints, where the dual variables are updated twice with different
stepsizes. Under proper assumptions instead of using the so-called
Kurdyka-Lojasiewicz inequality, convergence of the proposed algorithm as well
as its pointwise iteration-complexity are analyzed in terms of the
corresponding augmented Lagrangian function and the primal-dual residuals,
respectively. Performance of our algorithm is verified by some preliminary
numerical examples on applications in sparse nonconvex/convex regularized
minimization signal processing problems.

The recent advancement in lithium niobate on insulator (LNOI) technology is
revolutionizing the optoelectronic industry as devices of higher performance,
lower power consumption, and smaller footprint can be realized due to the high
optical confinement in the structures. The LNOI platform offers both large
\c{hi}(2) and \c{hi}(3) nonlinearities along with the power of dispersion
engineering, enabling brand new nonlinear photonic devices and applications
towards the next generation of integrated photonic circuits. However, the Raman
scattering, one of the most important nonlinear phenomena, have not been
extensively studied, neither was its influences in dispersion-engineered LNOI
nano-devices. In this work, we characterize the Raman radiation spectra in a
monolithic lithium niobate (LN) microresonator via selective excitation of
Raman-active phonon modes. Remarkably, the dominant mode for Raman oscillation
is observed in the backward direction for a continuous-wave pump threshold
power of 20 mW with a reportedly highest differential quantum efficiency of 46
%. In addition, we explore the effects of Raman scattering on Kerr optical
frequency combs generation. We achieve, for the first time, soliton modelocking
on a X-cut LNOI chip through sufficient suppression of the Raman effect via
cavity geometry control. Our analysis of the Raman effect provides guidance for
the development of future chip-based photonic devices on the LNOI platform.

The adsorption of iron phthalocyanine (FePc) on the passivated H/Si(111)
surface is explored from first principles. We find that the organic molecule is
predominantly physisorbed with a distance to the surface of $2.6 \pm 0.1$
Angstrom, but also exhibits sizable resonance with the underlying substrate.
This establishes the present system as interesting mixed
covalent-van-der-Waals-bound test case, which we use to compare the impact of
different approaches to van-der-Waals interactions. (Spin-polarized) scanning
tunneling microscopy (SP STM) images are simulated, selectively accessing
different molecular orbitals via the applied bias voltage in the spirit of
scanning tunneling spectroscopy. Comparison with experimental STM images
reveals very good agreement. We find a significant magnetic contrast exceeding
$\pm 1$ Angstrom in the SP STM images for $-2$ and $+1.5$ V. Binding energies
of different (transition metal) atoms in the center of the Pc ring are
presented, which particularly show that Fe is strongly bound in the molecule
(about $9.6$ eV). Finally, we discuss different reactions for subsurface doping
by room-temperature FePc deposition and point out two feasible reactions.

The local spectroscopic signatures of metamagnetic criticality in Sr3Ru2O7
were explored using scanning tunneling microscopy (STM). Singular features in
the tunneling spectrum were found close to the Fermi level, as would be
expected in a Stoner picture of itinerant electron metamagnetism. These
features showed a pronounced magnetic field dependence across the metamagnetic
critical point, which cannot be understood in terms of a naive Stoner theory.
In addition, a pseudo-gap structure was observed over several tens of meV,
accompanied by a c(2x2) superstructure in STM images. This result represents a
new electronic ordering at the surface in the absence of any measurable surface
reconstruction.

The shift to electronic medical records (EMRs) has engendered research into
machine learning and natural language technologies to analyze patient records,
and to predict from these clinical outcomes of interest. Two observations
motivate our aims here. First, unstructured notes contained within EMR often
contain key information, and hence should be exploited by models. Second, while
strong predictive performance is important, interpretability of models is
perhaps equally so for applications in this domain. Together, these points
suggest that neural models for EMR may benefit from incorporation of attention
over notes, which one may hope will both yield performance gains and afford
transparency in predictions. In this work we perform experiments to explore
this question using two EMR corpora and four different predictive tasks, that:
(i) inclusion of attention mechanisms is critical for neural encoder modules
that operate over notes fields in order to yield competitive performance, but,
(ii) unfortunately, while these boost predictive performance, it is decidedly
less clear whether they provide meaningful support for predictions.

A radiative transport model is used to study kinetic equilibration during the
early stage of a relativistic heavy ion collision. The parton system is found
to be able to overcome expansion and move toward thermalization via parton
collisions. Scaling behaviors show up in both the pressure anisotropy and the
energy density evolutions. In particular, the pressure anisotropy evolution
shows an approximate alpha_s scaling when radiative processes are included. It
approaches an asymptotic time evolution on a time scale of 1 to 2 fm/c. The
energy density evolution shows an asymptotic time evolution that decreases
slower than the ideal hydro evolution. These observations indicate that partial
thermalization can be achieved and viscosity is important for the evolution
during the early longitudinal expansion stage of a relativistic heavy ion
collision.

Exploring quantum phenomena in a curved spacetime is an emerging
interdisciplinary area relating many fields in physics such as general
relativity, thermodynamics, and quantum information. One famous prediction is
the Hawking-Unruh thermal radiation, the manifestation of Minkowski vacuum in
an accelerating reference frame. We simulate the radiation by evolving a
parametrically driven Bose-Einstein condensate of $\approx 10^5$ atoms, which
radiates coherent pairs of atoms with opposite momenta. We observe a matterwave
field which follows a Boltzmann distribution for a local observer. The
extracted temperature and entropy from the atomic distribution are in agreement
with Unruh's predictions. We further observe the long-distance phase coherence
and temporal reversibility of emitted matter-waves, hallmarks that distinguish
Unruh radiations from classical counterparts. Our results may lead to further
insights regarding the nature of the Hawking and Unruh effects and behaviors of
quantum physics in a curved spacetime.

In this work we use a low order dynamo model and study under which conditions
can it reproduce solar grand minima. We begin by building the phase space of a
proxy for the toroidal component of the solar magnetic field and we develop a
model, derived from mean field dynamo theory, that gives the time evolution of
the toroidal field. This model is characterized by a non-linear oscillator
whose coefficients retain most of the physics behind dynamo theory. In the
derivation of the model we also include stochastic oscillations in the $\alpha$
effect. We found no evidences that stochastic fluctuations in a linear $\alpha$
effect can trigger grand minima episodes in this model. In contrast, the model
used points out that possible mechanism that can trigger grand minima should
involve the meridional circulation, magnetic diffusivity or field
intensification by buoyancy driven instabilities.

The study of connectivity patterns in networks has brought novel insights
across diverse fields ranging from neurosciences to epidemic spreading or
climate. In this context, betweenness centrality has demonstrated to be a very
effective measure to identify nodes that act as focus of congestion, or
bottlenecks, in the network. However, there is not a way to define betweenness
outside the network framework. By analytically linking dynamical systems and
network theory, we provide a trajectory-based formulation of betweenness,
called Lagrangian betweenness, as a function of Lyapunov exponents. This
extends the concept of betweenness beyond the context of network theory
relating hyperbolic points and heteroclinic connections in any dynamical system
to the structural bottlenecks of the network associated with it. Using modeled
and observational velocity fields, we show that such bottlenecks are present
and surprisingly persistent in the oceanic circulation across different
spatio-temporal scales and we illustrate the role of these areas in driving
fluid transport over vast oceanic regions. Analyzing plankton abundance data
from the Kuroshio region of the Pacific Ocean, we find significant spatial
correlations between measures of diversity and betweenness, suggesting promise
for ecological applications.

7 month life span!
Great mattress.... but has a VERY SHORT life!!! We’ve only had ours for 7 months and it already sags In the middle and is so uncomfortable to sleep on now!!! Would have been better off buying a more expensive mattress so I didn’t have to turn around and by a brand new one every 7 months.

Driving Lessons From the writer of the critically acclaimed films, Mrs. Brown and Charlotte Gray, Jeremy Brock brings a touching heartfelt dramedy starring Academy Award Nominees Julie Walters and Laura Linney and from the Harry Potter series, Rupert Grint. The beautiful portrait tells the story of Ben Marshall, (Rupert Grint) a seventeen year old boy being held captive in the heart of his religiously neurotic mother Laura (Laura Linney). After his school year ends he decides to take a job with a clever, free-spirited, and "heavy on the bottle" retired actress, Evie Walton (Julie Walters). The pair embarks upon wonderful adventures from camping to walks around the block to the simple conversations about life. Challenging the domineering mother, as well as each other along the way, the two develop a beautiful bond that revolutionizes both their lives.<br /><br />The comedic elements are flawless and precise especially coming from the British veteran, Julie Walters. Brock uses his unique style to create an infamous and loving nature that first time directors could only dream. Directing comes naturally to Brock as he builds up stunning imagery that breaks the surfaces and plunges the viewer down into an overabundance of adoration and creation. Even the subtle score by unknown composers Clive Carroll and John Renbourn accentuate the tone and manner Brock had no trouble in generating.<br /><br />Laura Linney is always making her mark in films as she does as "Laura." The bossy and overbearing mother is at times unbearable and with Linney at the helm of it we are engulfed into that persona. The complexity of her character couldn't have been more flawlessly portrayed by anyone else. Rupert Grint breaks away from "Ron Weasley" and tries on someone new. His performance is more responsive than loquacious but Grint gives us someone brand new to a child performance and the viewer gets to enjoy it. But the standout is coming from Oscar nominated actress Julie Walters who gives "Evie" a life of her own. Despite the role being clearly a leading one, Walters fairs better in the supporting category where I believe she can simply take home the prize. "Evie" is a mix of "Clementine Kruczynski" and "Mrs. Laura Henderson" with her free spirit and lovable persona. Hopefully her role will not go unnoticed this awards season.<br /><br />Driving Lessons isn't an "out of this world" experience but a fine, enjoyable one that any viewer could just kick back and learn a little something about life, love, and friendship coming in the forms of the most beautiful colors and sizes.<br /><br />Grade: ***/****

As a long-time fan of Superman from the comics, through the 1950s series, the first two of the Chris Reeves films and Lois & Clark, and finally Smallville, I was *really* hoping for something clever with "Superman Returns".<br /><br />Instead we got Lex Luthor making *another* attempt at real-estate conversion, another Superman-beaten-up-while-wearing-kryptonite sequence, and internal inconsistencies: he couldn't stop himself falling into the ocean when stuck with 6" of kryptonite, but when Lois breaks off 3" of it, *leaving the rest embedded in him*, he can lift *a continent* into space?? Really, the only hero in the story was Lois' partner - I can't remember his name off-hand. He did all kinds of life-saving, heroic things with nothing but guts and skill - no superpowers, no invulnerability...just a normal human.<br /><br />They keep making Superman so small. Why can't we have Superman battling Brainiac or fighting to save the universe from General Zod instead of Lex's petty schemes. Oh, I forgot...they're doing that in Smallville.<br /><br />Yeah...I think I'll stick to Smallville...<br /><br />You probably should, too...

We notice signatures of extreme events-like behavior in a laser based Ikeda
map. The trajectory of the system occasionally travels a large distance away
from the bounded chaotic region, which appears as intermittent spiking events
in the temporal dynamics. The large spiking events satisfy the conditions of
extreme events as usually observed in dynamical systems. The probability
density function of the large spiking events shows a long-tail distribution
consistent with the characteristics of rare events. The inter-event intervals
obey a Poisson-like distribution. We locate the parameter regions of extreme
events in phase diagrams. Furthermore, we study two Ikeda maps to explore how
and when extreme events terminates via mutual interaction. A pure diffusion of
information exchange is unable to terminate extreme events where synchronous
occurrence of extreme events is only possible even for large interaction. On
the other hand, a threshold-activated coupling can terminate extreme events
above a critical value of mutual interaction.

It's amazing that from a good, though not wonderful, film made back in the early Nineties, a whole franchise can grow. 'Stargate; SG1' is, without a doubt, a worthy addition to the science fiction genre and has the right to stand shoulder-to-shoulder with 'Star Trek' as the kings of sci-fi.<br /><br />Following on from the 1994 feature film 'Stargate', this series sees Stargate command (a military/science organisation) figuring out that the stargate system can be used to travel to various planets across the galaxy and beyond and the military sets up a number of teams to explore. SG1 is one such team, headed by military veteran Colonel Jack O'Neill, and includes archaeologist Doctor Daniel Jackson, military scientist Captain Samantha Carter and alien Teal'c, who has betrayed his overlord leaders in the hopes of one day freeing his people. Earth quickly makes an enemy of the Goa'uld, a parasitic race who use humans as hosts and think themselves equal to gods.<br /><br />The top-notch cast have much to be congratulated for in bringing this show to life. Richard Dean Anderson is perfect as the cynical and sarcastic O'Neill, who can shift from boyish to deadly in the blink of an eye. Michael Shanks, as Daniel, brings heart and an will of steel to the character, who has grown from wide-eyed innocence to darker and more hard-bitten as the show has progressed. Amanda Tapping, as Carter, has perfected the balance between depicting her character's femininity without comprising the fact she is a strong, intelligent military scientist. Christopher Judge is excellent as the aloof Teal'c, who is able to depict the character's emotions with subtlety. And Don S Davis is perfect as the esteemed General Hammond who leads with a good balance of fairness and firmness.<br /><br />Almost all the episodes are are involving and portrayed with intelligence, reflecting on moral dilemmas as well as the friction between military interests and civilian beliefs (often shown through arguments between O'Neill and Jackson). Guest characters are solidly depicted and story arcs are handled in a manner that doesn't bore viewers. SG1 also excels in humour, from O'Neill's wisecracks to episodes that are just wacky and odd! SG1 has everything from action to drama to romance to suspense to the heartbreaking scenes of death. It isn't just an excellent sci-fi show but is an excellent show, overall.

Another example of both the desperation and incompetence over at the Pepsi Center. The Nuggets offered themselves up as a sacrificial lamb to enable the Cavs to strength their bloated payroll and to help Indiana avoid losing George for nothing. In return they would get a player who has started to physically break down, whose shooting percentage has fallen to 42% and is owed $73 million over the next three seasons. As the NBA Finals this year demonstrated when an opponent chooses to defend Love he can be reduced to irrelevant to the game. The Nuggets already have that guy in Gallinari.
It is going to be the crowning achievement of the Connelly era when he hands that stiff Plumlee a $70 million contract - and Nurkic makes the All-Star team. Given the obvious lack of interest by other players in coming to Denver and of other teams in Gallinari I won't be shocked when Connelly signs Gallo to a $100 million plus extension. Regardless - 32 and 50.

In two-dimensional layered quantum materials, the stacking order of the
layers determines both the crystalline symmetry and electronic properties such
as the Berry curvature, topology and electron correlation. Electrical stimuli
can influence quasiparticle interactions and the free-energy landscape, making
it possible to dynamically modify the stacking order and reveal hidden
structures that host different quantum properties. Here we demonstrate
electrically driven stacking transitions that can be applied to design
nonvolatile memory based on Berry curvature in few-layer WTe$_2$. The interplay
of out-of-plane electric fields and electrostatic doping controls in-plane
interlayer sliding and creates multiple polar and centrosymmetric stacking
orders. In situ nonlinear Hall transport reveals such stacking rearrangements
result in a layer-parity-selective Berry curvature memory in momentum space,
where the sign reversal of the Berry curvature and its dipole only occurs in
odd-layer crystals. Our findings open an avenue towards exploring coupling
between topology, electron correlations, and ferroelectricity in hidden
stacking orders and demonstrate a new low-energy-cost, electrically controlled
topological memory in the atomically thin limit.

Nothing can prepare you for another lousy bimbo outing! This time, it's being brought to you by the never-inevitable Fred Olen Ray! As far as exploitation movies go, this one doesn't click! As science fiction, it's plain unoriginal! All that we see is an an ugly feminine android wearing a bikini out to destroy the Earth, and showing off all that's nearly bare to resist! Give me a f---ing break!!! If this kind of entertainment is your thing, then why not dust off those old SI swimsuit mags from the attic for a change?! This would have been much better if it didn't set the sleaze factor on very high, but that still wouldn't make this one great. I'd like to point out another film called THE ASSAULT (1996) by Jim Wynorski, which resembles the identity of ALIENATOR. It illustrates why top-notch 1st-person "femme fatale" action movies don't translate well in America. Sorry, fellas!

Despite progress in understanding radio relics, there are still open
questions regarding the underlying particle acceleration mechanisms. In this
paper we present deep 1--4 GHz VLA observations of CIZA\,J2242.8+5301
($z=0.1921$), a double radio relic cluster characterized by small projection on
the plane of the sky. Our VLA observations reveal, for the first time, the
complex morphology of the diffuse sources and the filamentary structure of the
northern relic. We discover new faint diffuse radio emission extending north of
the main northern relic. Our Mach number estimates for the northern and
southern relics, based on the radio spectral index map obtained using the VLA
observations and existing LOFAR and GMRT data, are consistent with previous
radio and X-ray studies ($\mathcal{M}_{\rm RN}=2.58\pm0.17$ and
$\mathcal{M}_{\rm RS}=2.10\pm0.08$). However, color-color diagrams and
modelings suggest a flatter injection spectral index than the one obtained from
the spectral index map, indicating that projection effects might be not
entirely negligible. The southern relic consists of five "arms". Embedded in
it, we find a tailed radio galaxy which seems to be connected to the relic. A
spectral index flattening, where the radio tail connects to the relic, is also
measured. We propose that the southern relic may trace AGN fossil electrons
that are re-accelerated at a shock, with an estimated strength of
$\mathcal{M}=2.4$. High-resolution mapping of other tailed radio galaxies also
supports a scenario where AGN fossil electrons are revived by the merger event
and could be related to the formation of some diffuse cluster radio emission.

Not remotely soft
Soft tiles was not the name they should have gone with. I will say was very easy to install and the pattern matched exactly what we have bought from another company while decorating my son's Room. I would like an increase on quality moving forward. I guess it is a cool feature that you can pull the animals out suffer yet it just causes a non even Plane at all times

and then the last Civil War battle was fought at Val Verde you know over there on the Texas border you had a lot of of groups heading for Mexico and they were cut off at the pass more or less at Eagle Pass and they didn't get across the river there so they're the last and that was actually after the war was over but it was the last

I just purchased An Zhan (Running out of time) on DVD and it was an excellent film I must say. Not really action-packed, in terms of gun play, but definitely exciting and witty. I do not think I have seen Andy Lau in better form. And the editing on this film was very well executed. Go watch this now if you are a fan of Lau or HK thiller/action film!

We propose a machine learning approach to address a key challenge in
materials science: predicting how fractures propagate in brittle materials
under stress, and how these materials ultimately fail. Our methods use deep
learning and train on simulation data from high-fidelity models, emulating the
results of these models while avoiding the overwhelming computational demands
associated with running a statistically significant sample of simulations. We
employ a graph convolutional network that recognizes features of the fracturing
material and a recurrent neural network that models the evolution of these
features, along with a novel form of data augmentation that compensates for the
modest size of our training data. We simultaneously generate predictions for
qualitatively distinct material properties. Results on fracture damage and
length are within 3% of their simulated values, and results on time to material
failure, which is notoriously difficult to predict even with high-fidelity
models, are within approximately 15% of simulated values. Once trained, our
neural networks generate predictions within seconds, rather than the hours
needed to run a single simulation.

We construct certain $\theta$-series associated to number fields and prove
that for number fields of degree less than equal to 4, these $\theta$-series
are number field invariants. We also investigate whether or not the collection
of $\theta$-series associated to number fields of the same degree and
discriminant are linearly independent. This is known to be true if the degree
of the number field is less than or equal to 3. We do not prove in this paper
that they are linearly independent in general but we do give computational and
heuristic evidence that we would expect them to be.

We propose a device model that elucidates the role of domain walls in the
photovoltaic effect in multi-domain ferroelectric perovskites. The model
accounts for the intricate interplay between ferroelectric polarization, space
charges, photo-generation and electronic transport. When applied to bismuth
ferrite, results show a significant electric potential step across both
71-degree and 109-degree domain walls, which in turn contributes to the
photovoltaic (PV) effect. We also find a strong correlation between
polarization and oxygen octahedra tilts, which indicates the nontrivial role of
the latter in the PV effect. The domain wall-based PV effect is further shown
to be additive in nature, allowing for the possibility of generating
above-bandgap voltage

In this paper, we study the back-end of simultaneous localization and mapping
(SLAM) problem in deforming environment, where robot localizes itself and
tracks multiple non-rigid soft surface using its onboard sensor measurements.
An elaborate analysis is conducted on conventional deformation modelling
method, Embedded Deformation (ED) graph. We demonstrate and prove that the ED
graph widely used in such scenarios is unobservable and leads to multiple
solutions unless suitable priors are provided. Example as well as theoretical
prove are provided to show the ambiguity of ED graph and camera pose. In
modelling non-rigid scenario with ED graph, motion priors of the deforming
environment is essential to separate robot pose and deforming environment. The
conclusion can be extrapolated to any free form deformation formulation. In
solving the observability, this research proposes a preliminary deformable SLAM
approach to estimate robot pose in complex environments that exhibits regular
motion. A strategy that approximates deformed shape using a linear combination
of several previous shapes is proposed to avoid the ambiguity in robot movement
and rigid and non-rigid motions of the environment. Fisher information matrix
rank analysis with a base case is discussed to prove the effectiveness.
Moreover, the proposed algorithm is validated extensively on Monte Carlo
simulations and real experiments. It is demonstrated that the new algorithm
significantly outperforms conventional rigid SLAM and ED based SLAM especially
in scenarios where there is large deformation.

With the exception of the sound none of the above are really criticisms for this type of no budget, (truly) independent horror film. Make up effects and gore are very good and the lead actor was effective, the lead actress although attractive needs some coaching as she was particularly poor.<br /><br />The major problem with Frightworld is it's length, at 108 minutes its half an hour too long to be effective as a slasher movie, plot wise only about ten minute of the first fifty are relevant.<br /><br />In places it is visually engaging and sometimes the lack of lighting works in the films favour. However when this is combined with the poor sound as is the case with most of the film large sections are difficult to watch.<br /><br />This could certainly be an entertaining if unoriginal "serial killer back from the dead" movie with some judicious and ruthless editing, in its current form it plays like an unfinished rough cut.

The only reason for me for watching this little known Irish film was the question could Mike Myers have played a normal, dramatic character. Well, he could and his acting was pretty good but unfortunately that was probably the only good thing that I can say about this film. In the beginning film follows life of twelve years old orphan Mickey who lives with his brother and sister with their somewhat eccentric grandma. Despite some strong language it looks like a family film but after a while it becomes clearly that Pete's Meteor is a hardly suitable for young audience drama. And the worst is that it is a drama with so much ridiculous and even totally implausible plot. One preposterous story line turns into another and all the time there is no much sense in the events on screen. I suppose when a life drama needs a meteor or what is more something that looks like even more ridiculous spiritual content that's a really bad sign. The characters are not much better than a story. Despite all his troubles young Mickey by no means is not a likable character but it's clearly was somehow we were supposed to care about him and even feel strong sympathy to him. It doesn't work. The same thing with other characters. They are mostly as ridiculous as the story itself with the title character (although he wasn't the main character) as the only bright spot. Towards the end of the movie I still had a strong hope that there is something behind of all that improbability and absurdity. Unfortunately even if the writer of the story had such intentions (and I'm sure he had) in the film they are hidden and practically imperceptible under such a weird script. <br /><br />Grade: 3 out of 10. Those of you who are interested in seeing Mike Myers as a drama actor can watch Pete's Meteor for that reason but the rest of viewers most likely will be bitterly disappointed.

Let X be a real Banach space. We prove that the existence of an injective,
positive, symmetric and not strictly singular operator from X into its dual
implies that either X admits an equivalent Hilbertian norm or it contains a
nontrivially complemented subspace which is isomorphic to a Hilbert space. We
also treat the non-symmetric case.

We present results from a study of Type I critical phenomena in the dynamics
of general relativistic boson stars in spherical symmetry. The boson stars are
modelled with a minimally coupled, massive complex field (with no explicit
self-interaction), and are driven to the threshold of black hole formation via
their gravitational interaction with an initially imploding pulse of massless
scalar field. Using a distinct coordinate system, we reproduce previous results
[1,2], including the scaling of the lifetime of near-critical configurations,
as well as the fact that such configurations are well described as perturbed,
one-mode-unstable boson stars. In addition, we make a detailed study of the
long-time evolution of marginally subcritical configurations. Contrary to
previous claims [1,2], we find that the end state in such cases does not
involve dispersal of the bulk of the boson star field to large radial
distances, but instead can be generically described by a stable boson star
executing large amplitude oscillations. Furthermore we show that these
oscillations can be largely identified as excitations of the fundamental mode
associated with the final boson star, as computed in perturbation theory.

We investigate the evolution of transverse spin in tightly focused circularly
polarized beams of light, where spin-orbit coupling causes a local rotation of
the polarization ellipses upon propagation through the focal volume. The effect
can be explained as a relative Gouy-phase shift between the circularly
polarized transverse field and the longitudinal field carrying orbital angular
momentum. The corresponding rotation of the electric transverse spin density is
observed experimentally by utilizing a recently developed reconstruction
scheme, which relies on transverse-spin-dependent directional scattering of a
nano-probe.

Several properties of a hyepergeometric series related to Gromov-Witten
theory of some Calabi-Yau geometries was studied in [8]. These properties play
basic role in the study of higher genus Gromov-Witten theories. We extend the
results of [8] to equivariant setting for the study of higher genus equivariant
Gromov-Witten theories of some Calabi-Yau geometries.

Polar codes are designed for parallel binary-input additive white Gaussian
noise (BiAWGN) channels with an average power constraint. The two main design
choices are: the mapping between codeword bits and channels of different
quality, and the power allocation under the average power constraint.
Information theory suggests to allocate power such that the sum of mutual
information (MI) terms is maximized. However, a power allocation specific to
polar codes shows significant gains.

Event cameras are bio-inspired vision sensors that mimic retinas to
asynchronously report per-pixel intensity changes rather than outputting an
actual intensity image at regular intervals. This new paradigm of image sensor
offers significant potential advantages; namely, sparse and non-redundant data
representation. Unfortunately, however, most of the existing artificial neural
network architectures, such as a CNN, require dense synchronous input data, and
therefore, cannot make use of the sparseness of the data. We propose EventNet,
a neural network designed for real-time processing of asynchronous event
streams in a recursive and event-wise manner. EventNet models dependence of the
output on tens of thousands of causal events recursively using a novel temporal
coding scheme. As a result, at inference time, our network operates in an
event-wise manner that is realized with very few sum-of-the-product
operations---look-up table and temporal feature aggregation---which enables
processing of 1 mega or more events per second on standard CPU. In experiments
using real data, we demonstrated the real-time performance and robustness of
our framework.

I like my Ronald Colman dashing and debonair, the fellow you see in such films as If I Were King and Kismet. I like him as the epitome of civilization as in The Lost Horrizon and Random Harvest. A brooding Colman isn't a favorite of mine.<br /><br />But in A Double Life precisely because his part as actor Anthony John is so offbeat for him, Colman was recognized with a Best Actor Oscar for 1947. It became his best known part.<br /><br />Colman is an actor who really does take the Method quite seriously. He's just finished a successful run in a comedy of manners and he's quite the jovial fellow. For a change of pace now that that play has concluded its Broadway run, Colman is bringing a revival of Othello to New York. About as opposite a part as you can get.<br /><br />His leading lady in both is his former wife Signe Hasso who loves him dearly, but can't take his change of moods when he's at work. Colman loves her dearly as well and wants her back. But he's heading for a mental breakdown when he starts confusing himself with the jealous Moor Othello and Hasso with her role as Desdemona.<br /><br />Unfortunately Shelley Winters as a poor waitress who a depressed Colman picks up gets in the way of his madness and she winds up like poor Desdemona in the play. Killed in the same manner and now it's a matter for homicide cop Joe Sawyer.<br /><br />Colman's performance is so good that one does kind of wonder is this an occupational hazard with actors? I'd shudder to think so, were there any unsolved homicides in or around Laurence Olivier and Orson Welles then they essayed Othello. <br /><br />I could never quite buy the story for that reason, but I certainly do applaud Ronald Colman and what he did with the part. I'm sure there was a tinge of regret in him winning the Oscar though because one of the other nominees was his good friend William Powell for Life With Father. Others in the running that year were Gregory Peck for Gentlemen's Agreement, John Garfield for Body and Soul, and Michael Redgrave for Mourning Becomes Electra.<br /><br />Colman gets able support from the rest of the cast including Edmond O'Brien who finds himself in the unwanted part of Cassio in Colman's jealous fantasy. Still you will find no Iago equivalent in A Double Life, no one prodding the jealousy, it's all in his own mind.<br /><br />And that from one of the most cultivated and civilized minds of the last century.

I would have left the movie halfway through if I hadn't been with people who liked it. The movie is based on real incidents, but it's so over the top it didn't feel real at all. I have some psychological background, hang out with a lot of psychotherapists, and have known seriously crazy people, so it's not that I think people like this don't exist. But in the film, the only characters who seemed consistently human were Augusten's father (Alec Baldwin) and the young Augusten (Jack Kaedin). (Although Evan Rachel Wood was an intriguing diversion - very sexy with a wicked sense of fun). There were a few amusing moments, but the overall tone of the movie was grim, bizarre, and nasty. What a waste of an outstanding cast! As I watched them go through their turns, I just felt like I was watching an acting class. This was brought home during the credits, when a couple of people were shown just sitting there, not acting, not talking. Those few moments were more entertaining than the previous 2 hours.

The Japanese have probably the most sadistic movies around the world,and this is one of the strongest examples.With a running time at about an hour,it contains enough sexual violence and gore to disgust every single sane person on earth(even those who are hunting this type of movies).Three men and a woman are making a porn film.After some normally shots(which are pixelated),the girl is tied up,and the madmen cut her food,arm and tong.After that,they make a hole in her abdomen and a man has sexual intercourse with her intestines.He is knocked unconscious too and has his penis cut off.The special effects are good for an obviously low budget production(only the tong cut scene looks fake),and we can't talk about acting,direction or screenplay.After hearing a lot about this film,I was very happy when I finally found it.The first part is pretty boring,but the second one totally f***k up my mind,the torture and killing scenes being some of the most extreme and disturbing I have ever seen.The gore hounds will be satisfied by "Tumbling Doll of Flesh",but an unknowing viewer shouldn't even read the synopsis.

We study the $\Gamma$-limit of Ambrosio-Tortorelli-type functionals
$D_\varepsilon(u,v)$, whose dependence on the symmetrised gradient $e(u)$ is
different in $\mathbb{A} u$ and in $e(u)-\mathbb{A} u$, for a
$\mathbb{C}$-elliptic symmetric operator $\mathbb{A}$, in terms of the
prefactor depending on the phase-field variable $v$. This is intermediate
between an approximation for the Griffith brittle fracture energy and the one
for a cohesive energy by Focardi and Iurlano. In particular we prove that
$G(S)BD$ functions with bounded $\mathbb{A}$-variation are $(S)BD$.

It is increasingly suspected that the rare R Coronae Borealis (RCB) stars -
hydrogen-deficient and carbon-rich supergiant stars - are the products of
mergers of CO/He white-dwarf binary systems in the intermediate mass regime
($0.6<M_{Tot}<1.2 M_{\odot}$). Only 77 RCB stars are currently known in our
Galaxy while up to 1000 were expected. It is necessary to find more of these
peculiar and diverse stars to understand their origin and evolutionary path. We
are undertaking such a dedicated search. We plan to follow up spectroscopically
2356 targets of interest that were carefully selected using the all sky 2MASS
and WISE surveys. We have observed nearly 500 of these targets using optical
low-resolution spectrographs. These spectra were compared to synthetic spectra
from a new grid of MARCs hydrogen-deficient atmospheric models. Classical RCB
stars' photospheric temperatures range mostly from 4000 K to about 8500 K, and
therefore their spectra look very different showing the presence of carbon
molecules C$_2$ and CN up to $\sim$6800 K and solely atomic absorption lines
above that. We have put in place a series of criteria to distinguish RCB stars
from other AGB carbon-rich stars. We found 45 new RCB stars, including 30 Cold
($4000<T_{eff}<6800$ K), 14 Warm ($6800<T_{eff}<8500$ K) and one hot RCB
($T_{eff}>15000$ K). Forty of these belong to the Milky Way and five are
located in the Magellanic Clouds. We also confirmed that the long lasting
candidate KDM 5651 is indeed a new Magellanic RCB star, increasing the total
number of Magellanic Cloud RCB stars to 30. We have increased by $\sim$50\% the
total number of RCB stars known, now reaching 147. We also include a list of 14
strong RCB candidates, most certainly observed during a dust obscuration phase.
From the detection efficiency and success rate so far, we estimate that there
should be no more than 500 RCB stars/HdC stars in the Milky Way.

We have studied the long-term evolution of star clusters of the solar
neighborhood, starting from their birth in gaseous clumps until their complete
dissolution in the Galactic tidal field. We have combined the
"local-density-driven cluster formation model" of Parmentier & Pfalzner (2013)
with direct N-body simulations of clusters following instantaneous gas
expulsion.
We have studied the relation between cluster dissolution time, $t_{dis}$, and
cluster "initial" mass, $M_{init}$, defined as the cluster {mass at the end of
the dynamical response to gas expulsion (i.e. violent relaxation), when the
cluster age is 20-30 Myr}. We consider the "initial" mass to be consistent with
other works which neglect violent relaxation. The model clusters formed with a
high star formation efficiency (SFE -- i.e. gas mass fraction converted into
stars) follow a tight mass-dependent relation, in agreement with previous
theoretical studies. However, the low-SFE models present a large scatter in
both the "initial" mass and the dissolution time, and a shallower
mass-dependent relation than high-SFE clusters. Both groups differ in their
structural properties on the average. Combining two populations of clusters,
high- and low-SFE ones, with domination of the latter, yields a cluster
dissolution time for the solar neighborhood in agreement with that inferred
from observations, without any additional destructive processes such as giant
molecular cloud encounters.
An apparent mass-independent relation may emerge for our low-SFE clusters
when we neglect low-mass clusters (as expected for extra-galactic
observations), although more simulations are needed to investigate this aspect.

Great device, but doesn't do as well on grout as expected.
Chemicals stink... literally. But they do a better job for a fraction of the price when compared to this thing. I bought this to clean the grout on a house I'm selling. I cleaned an entire bathroom using acid wash but hated the smell and dangers of the fumes so I decided to invest in something that should have done the same. When I got this item in, I cleaned another bathroom and laundry room with it before the brass brushes wore down to the rim. I went through three brushes before I was done with the entire house (bedrooms were carpet). And when everything finally dried, there was blotches if dirt stains scattered around the grout still. The bathroom that was done using acid wash on the hand, was immaculate. But, I'm sure this will come in handy for other projects. It is easy to use and so far has held up mechanically.

We present a proof of the almost sure existence, uniqueness and coalescence
of directed semi-infinite geodesics in planar growth models that is based on
properties of an increment-stationary version of the growth process. The
argument is developed in the context of the exponential corner growth model. It
uses coupling, planar monotonicity, and properties of the stationary growth
process to derive the existence of Busemann functions, which in turn control
geodesics. This soft approach is in some situations an alternative to the
much-applied 20-year-old arguments of C. Newman and co-authors. Along the way
we derive some related results such as the distributional equality of the
directed geodesic tree and its dual, originally due to L. Pimentel.

The Arnoux-Rauzy systems are defined in \cite{ar}, both as symbolic systems
on three letters and exchanges of six intervals on the circle. In connection
with a conjecture of S.P. Novikov, we investigate the dynamical properties of
the interval exchanges, and precise their relation with the symbolic systems,
which was known only to be a semi-conjugacy; in order to do this, we define a
new system which is an exchange of nine intervals on the line (it was described
in \cite{abb} for a particular case). Our main result is that the
semi-conjugacy determines a measure-theoretic isomorphism (between the three
systems) under a diophantine (sufficient) condition, which is satisfied by
almost all Arnoux-Rauzy systems for a suitable measure; but, under another
condition, the interval exchanges are not uniquely ergodic and the isomorphism
does not hold for all invariant measures; finally, we give conditions for these
interval exchanges to be weakly mixing.

The crucial role of ambient correlations in determining thermodynamic
behavior is established. A class of entangled states of two macroscopic systems
is constructed such that each component is in a state of thermal equilibrium at
a given temperature, and when the two are allowed to interact heat can flow
from the colder to the hotter system. A dilute gas model exhibiting this
behavior is presented. This reversal of the thermodynamic arrow is a
consequence of the entanglement between the two systems, a condition that is
opposite to molecular chaos and shown to be unlikely in a low-entropy
environment. By contrast, the second law is established by proving Clausius'
inequality in a low-entropy environment. These general results strongly support
the expectation, first expressed by Boltzmann and subsequently elaborated by
others, that the second law is an emergent phenomenon that requires a
low-entropy cosmological environment, one that can effectively function as an
ideal information sink.

It's time we stopped funding these things and did something to make our existing cycling infrastructure function. One cannot go anywhere by bike in this city without being harassed by aggressive, drug-addled homeless people. They take over every critical underpass and won't let people through their stolen carts, unleashed pit bulls and passed-out bodies. No wonder we have lost 30% of our cyclists since 2009.

Driven by machine-learning tasks neural networks have demonstrated useful
capabilities as nonlinear hypothesis classifiers. The underlying technologies
performing the dot product multiplication, the summation, and the nonlinear
thresholding on the input data in electronics, however, are limited by the same
capacitive challenges known from electronic integrated circuits. The optical
domain, in contrast, provides low delay interconnectivity suitable for such
node distributed non Von Neumann architectures relying on dense node to node
communication. Thus, once the neural network's weights are set, the delay of
the network is just given by the time of flight of the photon, which is in the
picosecond range for photonic integrated circuits. However, the functionality
of memory for storing the trained weights does not exists in optics, thus
demanding a fresh look to explore synergies between photonics and electronics
in neural networks. Here we provide a roadmap to pave the way for emerging
hybridized photonic electronic neural networks by taking a detailed look into a
single node's perceptron, discussing how it can be realized in hybrid photonic
electronic heterogeneous technologies. We show that a set of materials exist
that exploit synergies with respect to a number of constrains including
electronic contacts, memory functionality, electrooptic modulation, optical
nonlinearity, and device packaging. We find that the material ITO, in
particular, could provide a viable path for both the perceptron weights and the
nonlinear activation function, while simultaneously being a foundry process
near material. We finally identify a number of challenges that, if solved,
could accelerate the adoption of such heterogeneous integration strategies of
emerging memory materials into integrated photonics platforms for real time
responsive neural networks.

A completely new approach to the Ising model in 1 to 5 dimensions is
developed. We employ $p,q$-binomial coefficients, a generalisation of the
binomial coefficients, to describe the magnetisation distributions of the Ising
model. For the complete graph this distribution corresponds exactly to the
limit case $p=q$. We take our investigation to the simple $d$-dimensional
lattices for $d=1,2,3,4,5$ and fit $p,q$-binomial distributions to our data,
some of which are exact but most are sampled. For $d=1$ and $d=5$ the
magnetisation distributions are remarkably well-fitted by $p,q$-binomial
distributions. For $d=4$ we are only slightly less successful, while for
$d=2,3$ we see some deviations (with exceptions!) between the $p,q$-binomial
and the Ising distribution. We begin the paper by giving results on the
behaviour of the $p,q$-distribution and its moment growth exponents given a
certain parameterization of $p,q$. Since the moment exponents are known for the
Ising model (or at least approximately for $d=3$) we can predict how $p,q$
should behave and compare this to our measured $p,q$. The results speak in
favour of the $p,q$-binomial distribution's correctness regarding their general
behaviour in comparison to the Ising model. The full extent to which they
correctly model the Ising distribution is not settled though.

We apply a data-based, linear dynamic estimator to reconstruct the velocity
field from measurements at a single sensor point in the wake of an aerofoil. In
particular, we consider a NACA0012 airfoil at $Re=600$ and $16^{\deg}$ angle of
attack. Under these conditions, the flow exhibits a vortex shedding limit
cycle. A reduced order model (ROM) of the flow field is extracted using proper
orthogonal decomposition (POD). Subsequently, a subspace system identification
algorithm (N4SID) is applied to extract directly the estimator matrices from
the reduced output of the system (the POD coefficients). We explore
systematically the effect of the number of states of the estimator, the sensor
location, the type of sensor measurements (one or both velocity components),
and the number of POD modes to be recovered. When the signal of a single
velocity component (in the stream wise or cross stream directions) is measured,
the reconstruction of the first two dominant POD modes strongly depends on the
sensor location. We explore this behaviour and provide a physical explanation
based on the non-linear mode interaction and the spatial distribution of the
modes. When however, both components are measured, the performance is very
robust, and is almost independent of the sensor location when the optimal
number of estimator states is used. Reconstruction of the less energetic modes
is more difficult, but still possible.

Stay away unless you want to look black and blue

I've seen this movie twice with my teenagers who love it. This one ought to be a cult fave! The best line, "Your dress is deeply cool!" says the Prince to Cinderella. Kathleen Turner shines as the stepmother. I also like the 1950's era cars and motorcycles. The melancholy prince is a great departure from the typical swashbuckler. He tries to stay cool, but fails to hide his love for the fairy-tale princess-to-be. Her slipper is not glass (truer to the original story), but Cinderella loses is nonetheless but gets it back from the heir to the throne. My only complaint is that it is not shown more and seems to be almost impossible to get. Hopefully Blockbuster or Amazon will start stocking this one sometime soon.

We consider an isolated system made of two pointlike bodies interacting at a
distance in the nonradiative approximation. Our framework is the covariant and
a priori Hamiltonian formalism of "predictive relativistic mechanics", founded
on the equal-time condition. The center of mass is rather a center of energy.
Individual energies are separately conserved and the meaning of their
positivity is discussed in terms of world-lines. Several results derived
decades ago under restrictive assumptions are extended to the general case.
Relative motion has a structure similar to that of a nonrelativistic one-body
motion in a stationnary external potential, but its evolution parameter is
generally not a linear function of the center-of-mass time, unless the relative
motion is circular (in this latter case the motion is periodic in the
center-of-mass time). Finally the case of an extreme mass ratio is
investigated. When this ratio tends to zero the heavy body coincides with the
center of mass provided that a certain first integral, related to the binding
energy is not too large.

OpenNRE is an open-source and extensible toolkit that provides a unified
framework to implement neural models for relation extraction (RE).
Specifically, by implementing typical RE methods, OpenNRE not only allows
developers to train custom models to extract structured relational facts from
the plain text but also supports quick model validation for researchers.
Besides, OpenNRE provides various functional RE modules based on both
TensorFlow and PyTorch to maintain sufficient modularity and extensibility,
making it becomes easy to incorporate new models into the framework. Besides
the toolkit, we also release an online system to meet real-time extraction
without any training and deploying. Meanwhile, the online system can extract
facts in various scenarios as well as aligning the extracted facts to Wikidata,
which may benefit various downstream knowledge-driven applications (e.g.,
information retrieval and question answering). More details of the toolkit and
online system can be obtained from http://github.com/thunlp/OpenNRE.

In this paper, we analyze content sharing between news sources in the
alternative and mainstream media using a dataset of 713K articles and 194
sources. We find that content sharing happens in tightly formed communities,
and these communities represent relatively homogeneous portions of the media
landscape. Through a mix-method analysis, we find several primary content
sharing behaviors. First, we find that the vast majority of shared articles are
only shared with similar news sources (i.e. same community). Second, we find
that despite these echo-chambers of sharing, specific sources, such as The
Drudge Report, mix content from both mainstream and conspiracy communities.
Third, we show that while these differing communities do not always share news
articles, they do report on the same events, but often with competing and
counter-narratives. Overall, we find that the news is homogeneous within
communities and diverse in between, creating different spirals of sameness.

We consider unital simple inductive limits of generalized dimension drop
C*-algebras They are so-called ASH-algebras and include all unital simple
AH-algebras and all dimension drop $C^*$-algebras. Suppose that $A$ is one of
these C*-algebras. We show that $A\otimes Q$ has tracial rank no more than one,
where $Q$ is the rational UHF-algebra. As a consequence, we obtain the
following classification result: Let $A$ and $B$ be two unital simple inductive
limits of generalized dimension drop algebras with no dimension growth. Then
$A\cong B$ if and only if they have the same Elliott invariant.

Under the assumption of thermal wind balance and effective entropy mixing in
constant rotation surfaces, the isorotational contours of the solar convective
zone may be reproduced with great fidelity. Even at this early stage of
development, this helioseismology fit may be used to put a lower bound on the
midlatitude {\em radial} solar entropy gradient, which in good accord with
standard mixing length theory. In this paper, we generalize this solar
calculation to fully convective stars (and potentially planets), retaining the
assumptions of thermal wind balance and effective entropy mixing in
isorotational surfaces. It is found that each isorotation contour is of the
form $R^2 = A+B\Phi(r)$, where $R$ is the radius from the rotation axis,
$\Phi(r)$ is the (assumed spherical) gravitational potential, and $A$ and $B$
are constant along the contour. This result is applied to simple models of
fully convective stars. Both solar-like surface rotation profiles (angular
velocity decreasing toward the poles) as well as "antisolar" profiles (angular
velocity increasing toward the poles) are modeled; the latter bear some
suggestive resemblance to numerical simulations. We also perform exploratory
studies of zonal surface flows similar to those seen in Jupiter and Saturn. In
addition to providing a practical framework for understanding the results of
large scale numerical simulations, our findings may also prove useful in
dynamical calculations for which a simple but viable model for the background
rotation profile in a convecting fluid is needed. Finally, our work bears
directly on an important goal of the CoRoT program: to elucidate the internal
structure of rotating, convecting stars.

Investigating the power density spectrum of fluctuations in Rayleigh-Taylor
(RT) interfacial mixing is a means of studying characteristic length- and
time-scales, anisotropies and anomalous processes. Guided by group theory,
analysing the invariance-based properties of the fluctuations, our work
examines raw time series from hot-wire anemometry measurements in the
experiment by Akula et al., JFM 816, 619-660 (2017). The results suggest that
the power density spectrum can be modelled as a compound function presented as
the product of a power law and an exponential. The data analysis is based on
Whittle's approximation of the power density spectrum for independent zero-mean
near-Gaussian signals to construct a Maximum likelihood Estimator (MLE) of the
parameters. Those that maximise the log-likelihood are computed numerically
through Newton-Raphson iteration. The Hessian of the log-likelihood is used to
evaluate the Fisher information matrix and provide an estimate of the
statistical error on the obtained parameters. The Kolmogorov-Smirnov test is
applied to analyse the goodness-of-fit, by verifying the hypothesis that the
ratio between the observed periodogram and the estimated power density spectrum
follows a chi-squared probability distribution. The dependence of the
parameters of the compound function is investigated on the range of mode
numbers over which the fit is performed. In the domain where the relative
errors of the power law exponent and the exponential decay rate are small and
the goodness-of-fit is excellent, the parameters of the compound function are
clearly defined, in agreement with the theory. The study of the power-law
spectra in RT mixing data suggests that rigorous physics-based statistical
methods can help researchers to see beyond visual inspection.

What is the deal with all these ethnic crime groups copying Italian mafia related movies ? We all know the Godfather as in Don Vito Corleone, now we have this Mexican one which is just a strait out Copy. I cant see why other ethnic groups have to Mimic and imitate Italian mobsters, but it sure makes them look silly. They sure seem to be wanabee Italians. I would much prefer to see Mexicans perform there own ideas and like to see there own culture, and the way they do it, instead of copying ideas from The Godfather trilogy. Apart from that the movie was disappointing, seeing mexicans acting and trying to be Italians is not my thing. After watching this, I'm now going to Watch the "Real" Godfather so this movie can be erased from my memory.

In the first transformation scene, what is the music? I've heard it was "The Greeks Don't Get No Freeks". Is that right? I really liked that sound. I also liked the "Hyde's Got Nothing to Hide" in the final scenes. Truly a doper movie, but with many laughs and puns, sight gags, and slapstick. Madam Woo-Woo's place was reminiscent of some places I have visited myself. Ivy Venus has appeared in some other stuff that is truly amazing. She looks much different in the movie we're talking about, but her maturity didn't hurt her a bit. Mark Blankfield reminds one of Gene Wilder in some ways. Bess Armstrong was beautiful and maintained her beauty for a long time.

BackgroundRepetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation tool potentially modulating pathological brain activity. Its clinical effectiveness is hampered by varying results and characterized by inter-individual variability in treatment responses. RTMS individualization might constitute a useful strategy to overcome this variability. A precondition for this approach would be that repeatedly applied protocols result in reliable effects. The condition tinnitus provides the advantage of immediate behavioral consequences (tinnitus loudness changes) after interventions and thus offers an excellent model to exemplify TMS personalization.
ObjectiveThe aim was to investigate the test-retest reliability of short rTMS stimulations in modifying tinnitus loudness and oscillatory brain activity as well as to examine the feasibility of rTMS individualization in tinnitus.
MethodsThree short verum (1Hz, 10Hz, 20Hz; 200 pulses) and one sham (0.1Hz; 20 pulses) rTMS protocol were administered on two different days in 22 tinnitus patients. Before and after each protocol, oscillatory brain activity was recorded with electroencephalography (EEG) together with behavioral tinnitus loudness ratings. RTMS individualization was executed by dint of behavioral and electrophysiological responses. Stimulation responders were identified via consistent sham-superior increases in tinnitus loudness (behavioral responders) and alpha power increases or gamma power decreases (alpha responders/ gamma responders) in accordance to the prevalent neurophysiological models for tinnitus.
ResultsIt was feasible to identify individualized rTMS protocols featuring reliable tinnitus loudness changes (55% behavioral responder), alpha increases (91% alpha responder) and gamma decreases (100% gamma responder) respectively. Alpha responses primary occurred over parieto-occipital areas, whereas gamma responses mainly appeared over frontal regions. Contrary, test-retest correlation analyses per protocol on a group-level were not significant neither for behavioral nor for electrophysiological effects. No associations between behavioral and EEG responses were given.
ConclusionRTMS individualization via behavioral and electrophysiological data in tinnitus can be considered as a feasible approach to overcome low reliability on group-level. The present results open the discussion favoring personalization utilizing neurophysiological markers rather than behavioral responses. These insights are not only useful for the rTMS treatment of tinnitus but also for neuromodulation interventions in other pathologies as our results suggest that the individualization of stimulation protocols is feasible despite absent group-level reliability.

This paper presents the second data release of the Hyper Suprime-Cam Subaru
Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru
Telescope. The release includes data from 174 nights of observation through
January 2018. The Wide layer data cover about 300 deg^2 in all five broadband
filters (grizy) to the nominal survey exposure (10min in gr and 20min in izy).
Partially observed areas are also included in the release; about 1100 deg^2 is
observed in at least one filter and one exposure. The median seeing in the
i-band is 0.6 arcsec, demonstrating the superb image quality of the survey. The
Deep (26 deg^2) and UltraDeep (4 deg^2) data are jointly processed and the
UltraDeep-COSMOS field reaches an unprecedented depth of i~28 at 5 sigma for
point sources. In addition to the broad-bands, narrow-band data are also
available in the Deep and UltraDeep fields. This release includes a major
update to the processing pipeline, including improved sky subtraction, PSF
modeling, object detection, and artifact rejection. The overall data quality
has been improved, but this release is not without problems; there is a
persistent deblender problem as well as new issues with masks around bright
stars. The user is encouraged to review the issue list before utilizing the
data for scientific explorations. All the image products as well as catalog
products are available for download. The catalogs are also loaded to a
database, which provides an easy interface for users to retrieve data for
objects of interest. In addition to these main data products, detailed galaxy
shape measurements withheld from the Public Data Release 1 (PDR1) are now
available to the community. The shape catalog is drawn from the S16A internal
release, which has a larger area than PDR1 (160 deg^2). All products are
available at the data release site, https://hsc-release.mtk.nao.ac.jp/.

This paper presents our latest investigation on end-to-end automatic speech
recognition (ASR) for overlapped speech. We propose to train an end-to-end
system conditioned on speaker embeddings and further improved by transfer
learning from clean speech. This proposed framework does not require any
parallel non-overlapped speech materials and is independent of the number of
speakers. Our experimental results on overlapped speech datasets show that
joint conditioning on speaker embeddings and transfer learning significantly
improves the ASR performance.

......... and you get Chori Chori Chupke Chupke. Don't get me wrong, this movie is much less explicit (or not even) than Pretty Woman, but it (was) a new topic for Bollywood. The topic was accepted but it is far from Jism, Murder, and Julie. To tell you the truth, the topic is presented in a very clean manner. But the plot has it's number of clichés. The beginning of the movie is presented in a very "filmi" way. There are some very little plot holes. The movie picks up once Rani has her miscarriage where you feel that you are watching something other than a typical movie. Otherwise the whole family sequence felt overdone in the beginning. The acting couldn't have been any better. Salman Khan sometimes impresses, and sometimes lets you down. Over here he gave one of the best performances. On top of that his role is written so well, that you applaud every time he solves a problem. Rani Mukherjee was adequate. Throughout the movie, you feel for her character the most, but she is overshadowed by Preity Zinta. Preity Zinta is picture perfect. Out of the three, she gives everyone a run for their money. Its surprising how she can be just as convincing when she is innocent. And trust me, Madhubala is far from your girl next door. This role is one of the reasons why I rate her high. The supporting cast are like the family you see in HAHK, where they have no significance to the plot yet I found them tolerable here. The songs are pretty nice. The title song is my favorite of them all along with Dil Tera Mera Dil (Hearts). Mehndi Mehndi (Henna) and Dekhne Walon Ne (Look at the World's Sight) are two song that fit the film perfectly. Preity's cabaret number, Diwani Diwani (Crazy), could've been shortened while No. 1 Punjabi came across boring though it had good dancing. Otherwise the movie is definitely worth a watch.

Soft and cozy!
Almost the perfect bathrobe - doesn't stay wet after a shower, hood is big enough to cover my whole head, very soft and I like the 2 colors. Technically it fits, but I almost want to get a size up so that it will be more snuggie-like. It just makes me cringe a little to order a size XL! But when this one wears out I may order the XL for maximum coziness.

We present the construction of a gravitational action including an infinite
series of higher derivative terms. The outcome is a classically consistent
completion of a well-studied quadratic curvature theory. The closed form for
the full action is ghost-free bimetric theory, describing the interactions of a
massive and a massless spin-2 field. At energies much smaller than the spin-2
mass scale, the theory reduces to general relativity. For energies comparable
to the spin-2 mass, the higher derivative terms completing the Einstein-Hilbert
action capture the effects of the additional massive spin-2 field. The theory
is only ghost-free when the full series of higher derivatives is kept.

The study of spectral behavior of networks has gained enthusiasm over the
last few years. In particular, Random Matrix Theory (RMT) concepts have proven
to be useful. In discussing transition from regular behavior to fully chaotic
behavior it has been found that an extrapolation formula of the Brody type can
be used. In the present paper we analyze the regular to chaotic behavior of
Small World (SW) networks using an extension of the Gaussian Orthogonal
Ensemble. This RMT ensemble, coined the Deformed Gaussian Orthogonal Ensemble
(DGOE), supplies a natural foundation of the Brody formula. SW networks follow
GOE statistics till certain range of eigenvalues correlations depending upon
the strength of random connections. We show that for these regimes of SW
networks where spectral correlations do not follow GOE beyond certain range,
DGOE statistics models the correlations very well. The analysis performed in
this paper proves the utility of the DGOE in network physics, as much as it has
been useful in other physical systems.

At present it is generally believed that ``new physics'' effects contribute
to leptonic anomalous magnetic moment, a_l, via quantum loops only and they are
proportional to the squared lepton mass, (m_l)^2. An alternative mechanism for
a contribution by new physics is proposed. It occurs at the tree level and
exhibits a linear rather than quadratic dependence on m_l. This leads to a much
larger sensitivity of a_e to the new physics than was expected so far.

I propose a scheme for reconstructing the weak value of an observable without
the need for weak measurements. The post-selection in weak measurements is
replaced by an initial projector measurement. The observable can be measured
using any form of interaction, including projective measurements. The
reconstruction is effected by measuring the change in the expectation value of
the observable due to the projector measurement. The weak value may take
nonclassical values if the projector measurement disturbs the expectation value
of the observable.

This model will not last for a full year
I purchased this model in Feb of 2018. Today is Jan 17, 2019 and it is having to be replaced. The clean indicator light continually flashes no matter how often you run the clean cycle. Please do not tell me this is because of "minerals", or "hard water". I have a whole house filtration and softening system in which my filters are changed regularly. This is not the issue. Today began a new issue. The coffee pot begins to brew a pot, gets 1/3 of the water out of the reservoir, then beeps as if it is done. I'm having to repeatedly turn the unit back on 3 and 4 times (on my second pot today) to get a full pot to brew. I bought Cuisinart based on the fact that it used to be a trusted name. I had a model like this several years ago and it lasted me for over 5 years. However it seems that Cuisinart, like other manufacturers are content with cranking out cheap products for full retail price in the hope that when it breaks in a year, we'll come back and buy another one. Well, sorry but no. You've lost your chance. I will not buy Cuisinart again. It has become an unreliable brand.

We address the inverse problem that arises in compressed sensing of a
low-rank matrix. Our approach is to pose the inverse problem as an
approximation problem with a specified target rank of the solution. A simple
search over the target rank then provides the minimum rank solution satisfying
a prescribed data approximation bound. We propose an atomic decomposition that
provides an analogy between parsimonious representations of a sparse vector and
a low-rank matrix. Efficient greedy algorithms to solve the inverse problem for
the vector case are extended to the matrix case through this atomic
decomposition. In particular, we propose an efficient and guaranteed algorithm
named ADMiRA that extends CoSaMP, its analogue for the vector case. The
performance guarantee is given in terms of the rank-restricted isometry
property and bounds both the number of iterations and the error in the
approximate solution for the general case where the solution is approximately
low-rank and the measurements are noisy. With a sparse measurement operator
such as the one arising in the matrix completion problem, the computation in
ADMiRA is linear in the number of measurements. The numerical experiments for
the matrix completion problem show that, although the measurement operator in
this case does not satisfy the rank-restricted isometry property, ADMiRA is a
competitive algorithm for matrix completion.

We are concerned with the existence and asymptotic properties of solutions to
the following fourth-order Schr\"{o}dinger equation \begin{equation}\label{1}
{\Delta}^{2}u+\mu \Delta u-{\lambda}u={|u|}^{p-2}u, ~~~~x \in \R^{N}\\
\end{equation} under the normalized constraint
$$\int_{{\mathbb{R}^N}} {{u}^2}=a^2,$$ where $N\!\geq\!2$, $a,\mu\!>\!0$,
$2+\frac{8}{N}\!<\!p\!<\! 4^{*}\!=\!\frac{2N}{(N-4)^{+}}$ and $\lambda\in\R$
appears as a Lagrange multiplier. Since the second-order dispersion term
affects the structure of the corresponding energy functional $$
E_{\mu}(u)=\frac{1}{2}{||\Delta u||}_2^2-\frac{\mu}{2}{||\nabla
u||}_2^2-\frac{1}{p}{||u||}_p^p $$ we could find at least two normalized
solutions to (\ref{1}) if $2\!+\!\frac{8}{N}\!<\! p\!<\!{ 4^{*} }$ and
$\mu^{p\gamma_p-2}a^{p-2}\!<\!C$ for some explicit constant
$C\!=\!C(N,p)\!>\!0$ and $\gamma_p\!=\!\frac{N(p\!-\!2)}{4p}$. Furthermore, we
give some asymptotic properties of the normalized solutions to (\ref{1}) as
$\mu\to0^+$ and $a\to0^+$, respectively. In conclusion, we mainly extend the
results in \cite{DBon,dbJB}, which deal with (\ref{1}), from $\mu\leq0$ to the
case of $\mu>0$, and also extend the results in \cite{TJLu,Nbal}, which deal
with (\ref{1}), from $L^2$-subcritical and $L^2$-critical setting to
$L^2$-supercritical setting.

Spins in silicon quantum devices are promising candidates for large-scale
quantum computing. Gate-based sensing of spin qubits offers compact and
scalable readout with high fidelity, however further improvements in
sensitivity are required to meet the fidelity thresholds and measurement
timescales needed for the implementation of fast-feedback in error correction
protocols. Here, we combine radio-frequency gate-based sensing at 622 MHz with
a Josephson parametric amplifier (JPA), that operates in the 500-800 MHz band,
to reduce the integration time required to read the state of a silicon double
quantum dot formed in a nanowire transistor. Based on our achieved
signal-to-noise ratio (SNR), we estimate that singlet-triplet single-shot
readout with an average fidelity of 99.7% could be performed in 1 $\mu$s,
well-below the requirements for fault-tolerant readout and 30 times faster than
without the JPA. Additionally, the JPA allows operation at a lower RF power
while maintaining identical SNR. We determine a noise temperature of 200 mK
with a contribution from the JPA (25%), cryogenic amplifier (25%) and the
resonator (50%), showing routes to further increase the read-out speed.

The ultra-compact Low Mass X-ray Binary (LMXB) X1916-053, composed of a
neutron star and a semi-degenerated white dwarf, exhibits periodic X-ray dips
with variable width and depth. We have developed new methods to parameterize
the dip to systematically study its variations. This helps to further
understand binary and accretion disk behaviors. The RXTE 1998 observations
clearly show a 4.87d periodic variation of the dip width. This is probably due
to the nodal precession of the accretion disk, although there are no
significant sidebands in the spectrum from the epoch folding search. From the
negative superhump model (Larwood et. al. 1996), the mass ratio can be
estimated as q = 0.045. Combined with more than 24 years of historical data, we
found an orbital period derivative of $\dot{P}_{orb}/P_{orb}=(1.62 \pm
0.48)\times 10^{-7} yr^{-1}$ and established a quadratic ephemeris for the
X-ray dips. The period derivative seems inconsistent with the prediction of the
standard model of binary orbital evolution proposed by Rappaport et. al.
(1987). On the other hand, the radiation-driven model (Tavani et. al. 1991) may
properly interpret the period derivative even though the large mass outflow
predicted by this model has never been observed in this system. With the best
ephemeris, we obtained that the standard deviation of primary dips are smaller
than that of secondary dips. This means that the primary dips are more stable
than the secondary dips. Thus, we conclude that the primary dips of X1916-053
occur from the bulge at the rim instead of the ring of the disk proposed by
Frank et. al. (1987).

There are plenty of potential interim superintendents while the search for a competent Superintendent is made. The idea that a superintendent, who has thus far shown such incompetent communication skills and has betrayed the trust of parents, teachers and students, is to have such a heavy hand in her replacement shows just how tone deaf Tom Koehler, Pam Knowles and Amy Kohnstamm are.
I cannot imagine how they think they are going to sell this bond to the public when it has been PROVEN that they lack the skills to manage our public buildings effectively. Carole and the PPS Board have failed by firing the entirety of custodial staff, hiring ineffective and corrupt contractors, failing to inspect and maintain facilities, keeping accurate maintenance logs or communicating effectively with parents. How can this board guarantee that they understand our concern? Step one: fire this superintendent. Step two: reprioritize the budget and put Health and Safety first.

Implementation of an editing process for Content MathML formulas in common
visual style is a real challenge for a software developer who does not really
want the user to have to understand the structure of Content MathML in order to
edit an expression, since it is expected that users are often not that
technically minded. In this paper, we demonstrate how this aim is achieved in
the context of the Formulator project and discuss features of this MathML
editor, which provides a user with a WYSIWYG editing style while authoring
MathML documents with Content or mixed markup. We also present the approach
taken to enhance availability of the MathML editor to end-users, demonstrating
an online version of the editor that runs inside a Web browser.

Will Work but not Durable
Cord is longer than expected which is good, but to have a Samsung Galaxy 7 phone and the connection is not as secure as I would like on the cable. All was working well until my phone fell while charging the connection from the cable bent and the cable no longer works. I can use the charger with another cable I happen to have. So for the price you get what you pay for.

For a digraph $D$, the niche hypergraph $NH(D)$ of $D$ is the hypergraph
having the same set of vertices as $D$ and the set of hyperedges is
\begin{align} E(NH(D)) &= \{e \subseteq V(D) : |e| \geq 2~and~there~exists~v
\in V(D)~such~that~e = N_{D}^{-}(v)\notag
&~~~~~~~or~e = N_{D}^{+}(v)\}.\notag \end{align} A digraph is said to be
acyclic if it has no directed cycle as a subdigraph. For a given hypergraph
$H$, the niche number $\hat{n}(H)$ is the smallest integer such that $H$
together with $\hat{n}(H)$ isolated vertices is the niche hypergraph of an
acyclic digraph. In this paper, we study the niche number of linear hypertrees
with maximum degree two. By our result, we can conclude for a special case that
if $H$ is a linear hypertree with $\Delta(H) = 2$ and anti-rank three, then
$\hat{n}(H) = 0$. We also prove that the maximum degree condition is best
possible. Moreover, it was proved that if $H$ is a hypergraph of rank $r$ whose
niche number is not infinity, then $\Delta(H) \leq 2r$. In this paper, we give
a construction of hypertrees whose niche number is $0$ of prescribed maximum
degree from $3$ to $2r$.

For a locally compact, totally disconnected group $G$, a subgroup $H$ and a
character $\chi:H \to \mathbb{C}^{\times}$ we define a Hecke algebra
$\mathcal{H}_\chi$ and explore the connection between commutativity of
$\mathcal{H}_\chi$ and the $\chi$-Gelfand property of $(G,H)$, i.e. the
property $\mathrm{dim}_\mathbb{C}(\rho^*)^{(H,\chi^{-1})} \leq 1$ for every
$\rho \in \mathrm{Irr}(G)$, the irreducible representations of $G$.
We show that the conditions of the Gelfand-Kazhdan criterion imply
commutativity of $\mathcal{H}_\chi$, and verify in several simple cases that
commutativity of $\mathcal{H}_\chi$ is equivalent to the $\chi$-Gelfand
property of $(G,H)$.
We then show that if $G$ is a connected reductive group over a $p$-adic field
$F$, and $G/H$ is $F$-spherical, then the cuspidal part of $\mathcal{H}_\chi$
is commutative if and only if $(G,H)$ satisfies the $\chi$-Gelfand property
with respect to all cuspidal representations ${\rho \in \mathrm{Irr}(G)}$.
We conclude by showing that if $(G,H)$ satisfies the $\chi$-Gelfand property
with respect to all irreducible $(H,\chi^{-1})$-tempered representations of $G$
then $\mathcal{H}_\chi$ is commutative.

We consider the stochastic heat equation with multiplicative noise
$u_t={1/2}\Delta u+ u \diamond \dot{W}$ in $\bR_{+} \times \bR^d$, where
$\diamond$ denotes the Wick product, and the solution is interpreted in the
mild sense. The noise $\dot W$ is fractional in time (with Hurst index $H \geq
1/2$), and colored in space (with spatial covariance kernel $f$). We prove that
if $f$ is the Riesz kernel of order $\alpha$, or the Bessel kernel of order
$\alpha<d$, then the sufficient condition for the existence of the solution is
$d \leq 2+\alpha$ (if $H>1/2$), respectively $d<2+\alpha$ (if $H=1/2$), whereas
if $f$ is the heat kernel or the Poisson kernel, then the equation has a
solution for any $d$. We give a representation of the $k$-th order moment of
the solution, in terms of an exponential moment of the "convoluted weighted"
intersection local time of $k$ independent $d$-dimensional Brownian motions.

We provide a quantitative picture of non-conserved interface growth from a
diffusive field making special emphasis on two main issues, the range of
validity of the effective small-slopes (interfacial) theories and the interplay
between the emergence of morphologically instabilities in the aggregate
dynamics, and its kinetic roughening properties. Taking for definiteness
electrochemical deposition as our experimental field of reference, our
theoretical approach makes use of two complementary approaches: interfacial
effective equations and a phase-field formulation of the electrodeposition
process. Both descriptions allow us to establish a close quantitative
connection between theory and experiments. Moreover, we are able to correlate
the anomalous scaling properties seen in some experiments with the failure of
the small slope approximation, and to assess the effective re-emergence of
standard kinetic roughening properties at very long times under appropriate
experimental conditions.

Misguided, miscast, murky, interminable lunacy given the high-gloss MGM A-budget treatment. Kate Hepburn plays a bride who comes to suspect her rich, handsome husband (Robert Taylor)is not the dreamboat she married but a psychotic killer. MGM's attempt at a Hitchcockian thriller is doomed from the start by a turgid, muddled, ludicrous script, and the idiotic casting of Hepburn as a jeopardized woman fearing for her life (who could ever imagine Hepburn afraid of anything?) Louis B. Mayer forgot to tell Vincent Minnelli he was directing a thriller, not a musical. Taylor is embarrassing. Only Robert Mitchum, also cast-against-type as a good guy, retains his dignity in a quiet, low-keyed performance. Karl Freund's ravishing cinematography creates images of eerie beauty--and was wasted on the wrong film. End result: Metro's "Parnell" of the 1940s.

The general context of this work is the feedback control of an
infinite-dimensional system so that the closed-loop system satisfies a
fading-memory property and achieves the setpoint tracking of a given reference
signal. More specifically, this paper is concerned with the Proportional
Integral (PI) regulation control of the left Neumann trace of a one-dimensional
reaction-diffusion equation with a delayed right Dirichlet boundary control. In
this setting, the studied reaction-diffusion equation might be either open-loop
stable or unstable. The proposed control strategy goes as follows. First, a
finite-dimensional truncated model that captures the unstable dynamics of the
original infinite-dimensional system is obtained via spectral decomposition.
The truncated model is then augmented by an integral component on the tracking
error of the left Neumann trace. After resorting to the Artstein transformation
to handle the control input delay, the PI controller is designed by pole
shifting. Stability of the resulting closed-loop infinite-dimensional system,
consisting of the original reaction-diffusion equation with the PI controller,
is then established thanks to an adequate Lyapunov function. In the case of a
time-varying reference input and a time-varying distributed disturbance, our
stability result takes the form of an exponential Input-to-State Stability
(ISS) estimate with fading memory. Finally, another exponential ISS estimate
with fading memory is established for the tracking performance of the reference
signal by the system output. In particular, these results assess the setpoint
regulation of the left Neumann trace in the presence of distributed
perturbations that converge to a steady-state value and with a time-derivative
that converges to zero. Numerical simulations are carried out to illustrate the
efficiency of our control strategy.

We study self-assembly in suspensions of supracolloidal polymer-like
structures made of crosslinked magnetic particles. Inspired by self-assembly
motifs observed for dipolar hard spheres, we focus on four different topologies
of the polymer-like structures: linear chains, rings, Y-shaped and X-shaped
polymers. We show how the presence of the crosslinkers, the number of beads in
the polymer and the magnetic interparticle interaction affect the structure of
the suspension. It turns out that for the same set of parameters, the rings are
the least active in assembling larger structures, whereas the system of Y- and
especially X-like magnetic polymers tend to form very large loose aggregates.

We study non-BPS black hole solutions to ungauged supergravity with 8
supercharges coupled to vector multiplets in four and five dimensions. We
identify a large class of five dimensional non-BPS solutions, which we call
"almost BPS", that are supersymmetric on local patches and satisfy a first
order flow governed by harmonic functions. By dimensional reduction, they give
rise to new non-BPS solutions in four dimensions. These solutions allow for
some nontrivial asymptotic moduli and multiple centres, similar to their
globally supersymmetric cousins. We explicitly discuss a single centre and a
two centre example.

This letter presents results on the precision measurement of the top quark
mass and a combination of the best CDF top mass measurements. A combination by
the TevEWWG (Tevatron electroweak working group) of the best top mass results
from CDF and D0 in Run 1 and Run 2 of the Tevatron is also presented. This
result is the current world average, and offers an uncertainty less than 1%.
The new mass value has been included in traditional LEP EWWG fits to precision
electroweak data, and implications for the Standard Model Higgs have been
derived.

We reconsider the fine-tuning problem of scalar-driven inflation arising from
the need to couple the inflaton to ordinary matter in order to make reheating
efficient. Quantum fluctuations of this matter induce Coleman-Weinberg
corrections to the inflaton potential, depending (for de Sitter background) in
a complex way on the ratio of the inflaton to the Hubble parameter. These
corrections are not Planck-suppressed and cannot be completely subtracted
because they are not even local for a general geometry. A previous study showed
that it is not satisfactory to subtract a local function of just the inflaton
and the {\it initial} Hubble parameter. This paper examines the other allowed
possibility of subtracting a local function of the inflaton and the Ricci
scalar. The problem in this case is that the new, scalar degree of freedom
induced by the subtraction causes inflation to end almost instantly.
