Depth estimation from a single image represents a fascinating, yet
challenging problem with countless applications. Recent works proved that this
task could be learned without direct supervision from ground truth labels
leveraging image synthesis on sequences or stereo pairs. Focusing on this
second case, in this paper we leverage stereo matching in order to improve
monocular depth estimation. To this aim we propose monoResMatch, a novel deep
architecture designed to infer depth from a single input image by synthesizing
features from a different point of view, horizontally aligned with the input
image, performing stereo matching between the two cues. In contrast to previous
works sharing this rationale, our network is the first trained end-to-end from
scratch. Moreover, we show how obtaining proxy ground truth annotation through
traditional stereo algorithms, such as Semi-Global Matching, enables more
accurate monocular depth estimation still countering the need for expensive
depth labels by keeping a self-supervised approach. Exhaustive experimental
results prove how the synergy between i) the proposed monoResMatch architecture
and ii) proxy-supervision attains state-of-the-art for self-supervised
monocular depth estimation. The code is publicly available at
https://github.com/fabiotosi92/monoResMatch-Tensorflow.

The article describes the new approach for quality improvement of automated
dialogue systems for customer support service. Analysis produced in the paper
demonstrates the dependency of the quality of the retrieval-based dialogue
system quality on the choice of negative responses. The proposed approach
implies choosing the negative samples according to the distribution of
responses in the train set. In this implementation the negative samples are
randomly chosen from the original response distribution and from the
"artificial" distribution of negative responses, such as uniform distribution
or the distribution obtained by transformation of the original one. The results
obtained for the implemented systems and reported in this paper confirm the
significant improvement of automated dialogue systems quality in case of using
the negative responses from transformed distribution.

We report on interferometric imaging of the CO J=1--0 and J=3--2 line
emission from the controversial QSO/galaxy pair HE 0450--2958. {\it The
detected CO J=1--0 line emission is found associated with the disturbed
companion galaxy not the luminous QSO,} and implies $\rm M_{gal}(H_2)\sim
(1-2)\times 10^{10} M_{\odot}$, which is $\ga 30% $ of the dynamical mass in
its CO-luminous region. Fueled by this large gas reservoir this galaxy is the
site of an intense starburst with $\rm SFR\sim 370 M_{\odot} yr^{-1}$, placing
it firmly on the upper gas-rich/star-forming end of Ultra Luminous Infrared
Galaxies (ULIRGs, $\rm L_{IR}>10^{12} L_{\odot}$). This makes HE 0450--2958 the
first case of extreme starburst and powerful QSO activity, intimately linked
(triggered by a strong interaction) but not coincident. The lack of CO emission
towards the QSO itself renews the controversy regarding its host galaxy by
making a gas-rich spiral (the typical host of Narrow Line Seyfert~1 AGNs) less
likely. Finally, given that HE 0450--2958 and similar IR-warm QSOs are
considered typical ULIRG$\to $(optically bright QSO) transition candidates, our
results raise the possibility that some may simply be {\it gas-rich/gas-poor
(e.g. spiral/elliptical) galaxy interactions} which ``activate'' an optically
bright unobscured QSO in the gas-poor galaxy, and a starburst in the gas-rich
one. We argue that such interactions may have gone largely unnoticed even in
the local Universe because the combination of tools necessary to disentagle the
progenitors (high resolution and S/N optical {\it and} CO imaging) became
available only recently.

Denote by g the Gauss measure on R^n and by L the Ornstein-Uhlenbeck
operator. In this paper we introduce a local Hardy space h^1(g) of Goldberg
type and we compare it with the Hardy space H^1(g) introduced in a previous
paper by Mauceri and Meda. We show that for each each positive r the imaginary
powers of the operator rI+L are unbounded from h^1(g) to L^1(g). This result is
in sharp contrast both with the fact that the imaginary powers are bounded from
$H^1(g}$ to L^1(g), and with the fact that for the Euclidean laplacian \Delta
and the Lebesgue measure \lambda) the imaginary powers of rI-\Delta are bounded
from the Goldberg space h^1(\lambda) to L^1(\lambda). We consider also the case
of Riemannian manifolds M with Riemannian measure m. We prove that, under
certain geometric assumptions on M, an operator T, bounded on L^2(m), and with
a kernel satisfying certain analytic assumptions, is bounded from H^1(m) to
L^1(m) if and only if it is bounded from h^1(m) to L^1(m). Here H^1(m) denotes
the Hardy space on locally doubling metric measure spaces introduced by the
authors in arXiv:0808.0146, and h^1(m) is a Goldberg type Hardy space on M,
equivalent to a space recently introduced by M. Taylor. The case of translation
invariant operators on homogeneous trees is also considered.

The place is a cesspool of neglect, poverty, criminality and desperation. Its population is a volatile mix of locals, immigrants (many of whom are illegal), workers, unemployed and criminals. To top it all, it resides on a steep slope.
I have no idea how the authorities think they can make this place liveable, without spending hundreds of millions on terracing and installing sewerage, water and power. It is also probably one of the most dangerous spots in the city.
Blocking will require some form of census, and many if it's residents don't want that, for obvious reasons.
The only way to get it right is for the community itself to identify the criminal elements that live among them, isolate them, and then participate in the "blocking" as temporary city employees. The city will have to break its own laws to expedite this process.

We have carried out a comparative theoretical study of the electronic
structure of the novel one-dimensional Ca$_3$CoRhO$_6$ and Ca$_3$FeRhO$_6$
systems. The insulating antiferromagnetic state for the Ca$_3$FeRhO$_6$ can be
well explained by band structure calculations with the closed shell high-spin
$d^5$ (Fe$^{3+}$) and low-spin $t_{2g}^{6}$ (Rh$^{3+}$) configurations. We
found for the Ca$_3$CoRhO$_6$ that the Co has a strong tendency to be $d^7$
(Co$^{2+}$) rather than $d^6$ (Co$^{3+}$), and that there is an orbital
degeneracy in the local Co electronic structure. We argue that it is the
spin-orbit coupling which will lift this degeneracy thereby enabling local spin
density approximation + Hubbard U (LSDA+U) band structure calculations to
generate the band gap. We predict that the orbital contribution to the magnetic
moment in Ca$_3$CoRhO$_6$ is substantial, i.e. significantly larger than 1
$\mu_B$ per formula unit. Moreover, we propose a model for the contrasting
intra-chain magnetism in both materials.

The module of Valabrega-Valla of the Jacobian ideal of a reduced projective
variety $V$ is the torsion of the Aluffi algebra. One considers the problem of
its vanishing in the case of where $V$ is a reduced set of points in the
projective plane. It is shown that the module is nonzero for several cases of a
special configuration class therein -- called $(s-r)$-{fold collinear
configuration}. A complete classification of types is given for $5$ and $6$
points in regard to this problem.

Hematopoietic stem cell (HSC) aging is a multifactorial event that leads to changes in HSC properties and function. These changes are intrinsically coordinated and affect the early hematopoiesis, involving hematopoietic stem and progenitor cells (HSPCs). The objective of this work is to better understand the mechanisms and factors controlling these changes. We have therefore developed an original strategy to construct a Boolean network of genes explaining the priming and homeostasis of HSCs (graphical abstract). Based on our previous scRNA-seq data, we performed an exhaustive analysis of the transcriptional network and identified active transcription modules or regulons along the differentiation trajectory of selected HSPC states. This global view of transcriptional regulation led us to focus on 15 components, 13 selected TFs (Tal1, Fli1, Gata2, Gata1, Zfpm1, Egr1, Junb, Ikzf1, Myc, Cebpa, Bclaf1, Klf1, Spi1) and 2 complexes regulating the ability of HSC to cycle (CDK4/6 - Cyclin D and CIP/KIP). We then defined the connections controlling the differentiation dynamics of HSC states and constructed an influence graph between the TFs involved in the dynamics by mixing observations from our scRNA-seq data and knowledge from the literature. Then, using answer set programming (ASP) and in silico perturbation analysis, we obtained a Boolean model which is the solution of a Boolean satisfiability problem. Finally, perturbation of the model based on age-related changes revealed important regulations, such as the overactivation of Egr1 and Junb or the loss of Cebpa activation by Gata2, which were found to be relevant for the myeloid bias of aged HSC. Our work shows the efficiency of the combination of manual and systematic methods to elaborate a Boolean model. The developed strategy led to the proposal of new regulatory mechanisms underlying the differentiation bias of aged HSCs, explaining the decreased transcriptional priming of HSCs to all mature cell types except megakaryocytes.

We carry out a series of high resolution ($1024\times 1024$) hydrodynamical
simulations to investigate the orbital evolution of Jupiter and Saturn embedded
in a gaseous protostellar disk. Our work extends the results in the classical
papers of Masset & Snellgrove (2001) and Morbidelli & Crida (2007) by exploring
various surface density profiles ($\sigma$), where $\sigma \propto
r^{-\alpha}$. The stability of the mean motion resonances(MMRs) caused by the
convergent migration of the two planets is studied as well. Our results show
that:(1) The gap formation process of Saturn is greatly delayed by the tidal
perturbation of Jupiter. These perturbations cause inward or outward runaway
migration of Saturn, depending on the density profiles on the disk. (2) The
convergent migration rate increases as $\alpha$ increases and the type of MMRs
depends on $\alpha$ as well. When $0<\alpha<1$, the convergent migration speed
of Jupiter and Saturn is relatively slow, thus they are trapped into 2:1 MMR.
When $\alpha>4/3$, Saturn passes through the $2:1$ MMR with Jupiter and is
captured into the $3:2$ MMR. (3) The $3:2$ MMR turns out to be unstable when
the eccentricity of Saturn ($e_s$) increases too high. The critical value above
which instability will set in is $e_s \sim 0.15$. We also observe that the two
planets are trapped into $2:1$ MMR after the break of $3:2$ MMR. This process
may provide useful information for the formation of orbital configuration
between Jupiter and Saturn in the Solar System.

We generalize the approach of Liu and Lawrence (1999) for multiple
changepoint problems where the number of changepoints is unknown. The approach
is based on dynamic programming recursion for efficient calculation of the
marginal probability of the data with the hidden parameters integrated out. For
the estimation of the hyperparameters, we propose to use Monte Carlo EM when
training data are available. We argue that there is some advantages of using
samples from the posterior which takes into account the uncertainty of the
changepoints, compared to the traditional MAP estimator, which is also more
expensive to compute in this context. The samples from the posterior obtained
by our algorithm are independent, getting rid of the convergence issue
associated with the MCMC approach. We illustrate our approach on limited
simulations and some real data set.

We present preliminary numerical evidence that the physical conditions in
high-mass star forming regions can arise from global gravitational infall, with
the velocity dispersions being caused primarily by infall motions rather than
random turbulence. To this end, we study the clumps and cores appearing in the
region of central collapse in a numerical simulation of the formation,
evolution, and subsequent collapse of a dense cloud out of a transonic
compression in the diffuse atomic ISM. The clumps have sizes $\sim 1$ pc,
masses of several hundred $M_\odot$, and three-dimensional velocity dispersions
$\sim 3$ km s$^{-1}$, in agreement with typical observed values for such
structures. The clumps break down into massive cores of sizes $\sim 0.1$ pc,
densities $\sim 10^5$, masses 2-300 $M_\odot$, with distributions of these
quantities that peak at the same values as the massive core sample in a recent
survey of the Cygnus X molecular cloud complex. Although preliminary, these
results suggest that high-mass star forming clumps may be in a state of global
gravitational collapse rather than in equilibrium supported by strong
turbulence.

We report low-temperature measurements of the electrical resistivity of
Yb(Rh1-xCox)2Si2 single crystals with 0 <= x <= 0.12. The isoelectronic
substitution of Co on the Rh site leads to a decrease of the unit cell volume
which stabilizes the antiferromagnetism. Consequently, the antiferromagnetic
transition temperature increases upon Co substitution. For x = 0.07 Co content
a subsequent low-temperature transition is observed in agreement with
susceptibility measurements and results on YbRh2Si2 under hydrostatic pressure.
Above the Neel transition the resistivity follows a non-Fermi liquid behavior
similar to that of YbRh2Si2.

Near extremal Kerr black holes are subject to the Thorne limit $a<a^*_{\rm
lim}=0.998$ in the case of thin disc accretion, or some generalized version of
this in other disc geometries. However any limit that differs from the
thermodynamics limit $a^* < 1$ can in principle be evaded in other
astrophysical configurations, and in particular if the near extremal black
holes are primordial and subject to evaporation by Hawking radiation only. We
derive the lower mass limit above which Hawking radiation is slow enough so
that a primordial black hole with a spin initially above some generalized
Thorne limit can still be above this limit today. Thus, we point out that the
observation of Kerr black holes with extremely high spin should be a hint of
either exotic astrophysical mechanisms or primordial origin.

We consider the Dirichlet form given by
\sE(f,f)&=&{1/2}\int_{\bR^d}\sum_{i,j=1}^d a_{ij}(x)\frac{\partial
f(x)}{\partial x_i} \frac{\partial f(x)}{\partial x_j} dx &+&\int_{\bR^d\times
\bR^d} (f(y)-f(x))^2J(x,y)dxdy. Under the assumption that the $\{a_{ij}\}$ are
symmetric and uniformly elliptic and with suitable conditions on $J$, the
nonlocal part, we obtain upper and lower bounds on the heat kernel of the
Dirichlet form. We also prove a Harnack inequality and a regularity theorem for
functions that are harmonic with respect to $\sE$.

We consider the generic problem of performing a global fit to many
independent data sets each with a different overall multiplicative
normalization uncertainty. We show that the methods in common use to treat
multiplicative uncertainties lead to systematic biases. We develop a method
which is unbiased, based on a self--consistent iterative procedure. We
demonstrate the use of this method by applying it to the determination of
parton distribution functions with the NNPDF methodology, which uses a Monte
Carlo method for uncertainty estimation.

This is beyond a shadow of a doubt the absolute worst movie I have ever seen. It's been a long time since I've seen it, but the jokes are NOT funny, the plot is painfully forseeable, calling the main characters stupid is to vastly upgrade their intelligence...uggh! I just wanted to punch Tom Arnold and make him cry because he wasted two hours of my life when I was done watching this piece of cinematic filth. I don't even know why I ever wanted to watch it, but remember if you see this movie: DON'T SAY I DIDN'T WARN YOU.<br /><br />PS Tom Arnold's character sings a song in this movie called "I'm My Own Grandfather." Nuff said.

In analogy with conventional quantum mechanics, non-commutative quantum
mechanics is formulated as a quantum system on the Hilbert space of
Hilbert-Schmidt operators acting on non-commutative configuration space. It is
argued that the standard quantum mechanical interpretation based on Positive
Operator Valued Measures, provides a sufficient framework for the consistent
interpretation of this quantum system. The implications of this formalism for
rotational and time reversal symmetry are discussed. The formalism is applied
to the free particle and harmonic oscillator in two dimensions and the physical
signatures of non commutativity are identified.

Security vulnerability analysis of Integrated Circuits using conventional
design-time validation and verification techniques (like simulations,
emulations, etc.) is generally a computationally intensive task and incomplete
by nature, especially under limited resources and time constraints. To overcome
this limitation, we propose a novel methodology based on model checking to
formally analyze security vulnerabilities in sequential circuits while
considering side-channel parameters like propagation delay, switching power,
and leakage power. In particular, we present a novel algorithm to efficiently
partition the state-space into corresponding smaller state-spaces to enable
distributed security analysis of complex sequential circuits and thereby
mitigating the associated state-space explosion due to their feedback loops. We
analyze multiple ISCAS89 and trust-hub benchmarks to demonstrate the efficacy
of our framework in identifying security vulnerabilities. The experimental
results show that ForASec successfully performs the complete analysis of the
given complex and large sequential circuits, and provides approximately 11x to
16x speedup in analysis time compared to state-of-the-art model checking-based
techniques. Moreover, it also identifies the number of gates required by an HT
that can go undetected for a given design and variability conditions.

Must have for those who cant reach their feet.
Overall rating is a 5. Having said that, the suction pads are small and wont hold on my textured shower floor. I wear a womens size 9W shoe and I can fit both feet on the pad at the same time. And by standing on it with one foot I can scrub the other foot. Love the longer bits in front that get between the toes. A quick rinse with the shower and its clean. I hang it up after every usr to make sure it dries. For those with tender or sensitive feet it might be a little stiff. But I love it. After a long day of being in work shoes my feet are smoother and more relaxed.

This movie lacked credibility for two reasons. One, no mayor of a major city, and New York is certainly as major as it gets. Would allow a borough in his city to degenerate into such a violent place to live; especially for voters who could have much to say about his or her future job security. All of the victims in the movie were mostly elderly, Jewish or defenseless. At 62-years of age, I have never seen a movie that depicted such utter lack of respect for authority as this movie did. Even "Escape from New York," which was fictional, up front, i.e. they told you that this was science fiction, didn't resort to such deep-seated violence. In this movie, most of the elderly victims were victimized and yet had guns but were unwilling to use them. Also, in this movie and I have not seen the prior two, is more lawless than the "Escape" movie. Secondly, gangs as far as my research shows have never been as cooperative as this movie makes them out to be. On the one hand they catch a gang member from another gang working in their area and he's killed. Yet when the heroes start shooting at the local gang bangers, the next gang over is welcomed with open arms. Outside gang members are always viewed as outsiders and are stopped. We are supposed to believe that when automatic weapons are used against our gang, the other gangs want to be all into it. Why did the outside gangs come to help? I believe that more than one gang from outside came to help. What did they come for? Another question, why was the gang leader in jail and why do fellow jail inmates ask his permission to attack Bronson's character? This was not a great movie and I could go on, but I won't.

We have obtained [Mg/Fe] for around 77% of the stars of the MILES library of
stellar spectra in order to include this important information into simple
stellar population (SSP) models. The abundance ratios, which were carefully
calibrated to a single uniform scale, were obtained through a compilation from
high spectral resolution works plus robust spectroscopic analysis at medium
resolution. The high resolution data provided an extensive control sample.
Average uncertainties (0.06 and 0.12 dex for the high and medium resolution
samples respectively) and the good coverage of the stars with [Mg/Fe] over the
MILES's parameter space will permit us to semi-empirically build up new SSP
models with accurate alpha-enhancements for ages older than 1 Gyr. This will
open new prospects for evolutionary stellar population synthesis.

We present a model of inflation in which the inflaton field is charged under
a triplet of $U(1)$ gauge fields. The model enjoys an internal $O(3)$ symmetry
supporting the isotropic FRW solution. With an appropriate coupling between the
gauge fields and the inflaton field, the system reaches an attractor regime in
which the gauge fields furnish a small constant fraction of the total energy
density. We decompose the scalar perturbations into the adiabatic and entropy
modes and calculate the contributions of the gauge fields into the curvature
perturbations power spectrum. We also calculate the entropy power spectrum and
the adiabatic-entropy cross correlation. In addition to the metric tensor
perturbations, there are tensor perturbations associated with the gauge field
perturbations which are coupled to metric tensor perturbations. We show that
the correction in primordial gravitational tensor power spectrum induced from
the matter tensor perturbation is a sensitive function of the gauge coupling.

In this paper we present a simple novel approach to tackle the challenges of
scaling and rotation of face images in face recognition. The proposed approach
registers the training and testing visual face images by log-polar
transformation, which is capable to handle complicacies introduced by scaling
and rotation. Log-polar images are projected into eigenspace and finally
classified using an improved multi-layer perceptron. In the experiments we have
used ORL face database and Object Tracking and Classification Beyond Visible
Spectrum (OTCBVS) database for visual face images. Experimental results show
that the proposed approach significantly improves the recognition performances
from visual to log-polar-visual face images. In case of ORL face database,
recognition rate for visual face images is 89.5% and that is increased to 97.5%
for log-polar-visual face images whereas for OTCBVS face database recognition
rate for visual images is 87.84% and 96.36% for log-polar-visual face images.

This paper reviews the current status of graphene transistors as potential
supplement to silicon CMOS technology. A short overview of graphene
manufacturing and metrology methods is followed by an introduction of
macroscopic graphene field effect transistors (FETs). The absence of an energy
band gap is shown to result in severe shortcomings for logic applications.
Possibilities to engineer a band gap in graphene FETs including quantum
confinement in graphene Nanoribbons (GNRs) and electrically or substrate
induced asymmetry in double and multi layer graphene are discussed. Graphene
FETs are shown to be of interest for analog radio frequency applications.
Finally, novel switching mechanisms in graphene transistors are briefly
introduced that could lead to future memory devices.

The net is an excellent movie! It's about Angela Bennett(in a great performance of Sandra Bullock) who is a computer expert who works for the Cathedral Company, cleaning virus and testing games for the clients. Angela is a typical nerd who doesn't have friends outside of the cyberspace,almost doesn't take vacations and go out, and stays almost all the time connected. One day her friend Dale Hessman(Ray McKinnon) asks her to help him,sending Angela a disk with a strange program that has many confidential informations. At the same night, when Dale was going to meet her, he is suddenly killed in a plane crash.Going to Mexico in her vacation,Angela meets a beautiful guy called Jack Devlin (Jeremy Northam)who shows to be a cold blood killer bastard and one of the guys behind all the secret of the Diskette.<br /><br />Her life then turns into a nightmare: All her records are erased and she is given the new identity of Ruth Marx, a woman with serious problems with the police.<br /><br />This movie is great because it shows how we, humans,depend a lot of the computers and machines(sometimes more that we should) and how vulnerable we are if someday ,someone decides to control and change our personal records,without letting us the chance to prove the error.

The Love Letter is one of my all-time favorite books, so naturally I was skeptical when I heard it was to become a movie. But, I liked it. I found myself grinning through the entire movie. I admit that it isn't a great movie but definitely a pleasant hour and a half. I thought that Capshaw and Scott were perfect as Helen and Johnny. Just as I pictured them. And the town and scenery were just right as well. I recommend this film, but don't expect too much, just enjoy it.

I am speechless, honestly I cannot understand how anyone could have conceded to a script like this, cast anyone in the film let alone direct it. The fact that I am writing this review feels like an insult to my fingers, this film should be thrown in to the dustbin rather than be reviewed. I am disappointed in Flex Alexander for even thinking about accepting such a POOR EXCUSE FOR A SCRIPT let alone essay the role. OMG! I think I just insulted the word "essay"...uh yeah I did. Y'know what, the less said about this mindless drivel, the better. You have been warned, nobody warned me I had to experience the horror myself. WATCH AT YOUR OWN RISK.

The people in this State rail against Children's Services. As such, parents are free to do pretty much whatever they want with their kids. They can say that the kids are home schooled, and that's that. This is what Alaskans and especially Tea Party Republicans have been after for years and years. This is an obvious outcome, and, of course, it is only a misdemeanor.

We investigate the vortex excitations induced by a spin-polarized current in
a magnetic nanopillar by means of micromagnetic simulations and analytical
calculations. Damped motion, stationary vortex rotation and the switching of
the vortex core are successively observed for increasing values of the current.
We demonstrate that even for small amplitude of the vortex motion, the
analytical description based the classical Thiele approach can yield
quantitatively and qualitatively unsound results. We suggest and validate a new
analytical technique based on the calculation of the energy dissipation.

Price and quality is good. It's just that it took me three hours to punch the hole and get the sizing correct on myself. I'd probably want to pay more money and get the sizing right than do the work myself at that point.

Inversion codes allow reconstructing a model atmosphere from observations.
With the inclusion of optically thick lines that form in the solar
chromosphere, such modelling is computationally very expensive because a
non-LTE evaluation of the radiation field is required. In this study, we
combine the results provided by these traditional methods with machine and deep
learning techniques to obtain similar-quality results in an easy-touse, much
faster way. We have applied these new methods to Mg II h&k lines observed by
IRIS. As a result, we are able to reconstruct the thermodynamic state
(temperature, line-of-sight velocity, non-thermal velocities, electron density,
etc.) in the chromosphere and upper photosphere of an area equivalent to an
active region in a few CPU minutes, speeding up the process by a factor of
$10^5$-$10^6$. The open-source code accompanying this paper will allow the
community to use IRIS observations to open a new window to a host of solar
phenomena.

This paper is concerned with a novel regularisation technique for solving
linear ill-posed operator equations in Hilbert spaces from data that is
corrupted by white noise. We combine convex penalty functionals with
extreme-value statistics of projections of the residuals on a given set of
sub-spaces in the image-space of the operator. We prove general consistency and
convergence rate results in the framework of Bregman-divergences which allows
for a vast range of penalty functionals. Various examples that indicate the
applicability of our approach will be discussed. We will illustrate in the
context of signal and image processing that the presented method constitutes a
locally adaptive reconstruction method.

Within two years, they plan to get married and go on a honeymoon: cost $25,000. In two or three years, they hope to have their first child, followed by a second one later. “We would like for one of us to be able to raise the kids, with one of us possibly taking time off,” Ken writes. “Do you have any financial suggestions on how to manage this?”
-------
I love how they write it as if it's so easy to have a child. In 2-3 years, the wife will be 35. That is the age where things start to go wrong and it starts to become harder to have kids. They might need to budget in IVF if they can't have children. They need to see whether they have any maternity/paternity benefits from their place of employment. No FA will tell you that.

nothing special
My husband liked them and the safety they would provide since he works on machinery and always had to remove his ring. Unfortunately the first time he wore it the center black part came off somewhere without his knowledge and he was left with just the red band with no center black piece. They are 2 separate pieces so im guessing the center broke because I don't see how the center could separate and just slide off his finger without him knowing. As far as im concerned I just threw away this money because he went back to his platinum ring. What a waste of money.

Sample-efficient exploration is crucial not only for discovering rewarding
experiences but also for adapting to environment changes in a task-agnostic
fashion. A principled treatment of the problem of optimal input synthesis for
system identification is provided within the framework of sequential Bayesian
experimental design. In this paper, we present an effective
trajectory-optimization-based approximate solution of this otherwise
intractable problem that models optimal exploration in an unknown Markov
decision process (MDP). By interleaving episodic exploration with Bayesian
nonlinear system identification, our algorithm takes advantage of the inductive
bias to explore in a directed manner, without assuming prior knowledge of the
MDP. Empirical evaluations indicate a clear advantage of the proposed algorithm
in terms of the rate of convergence and the final model fidelity when compared
to intrinsic-motivation-based algorithms employing exploration bonuses such as
prediction error and information gain. Moreover, our method maintains a
computational advantage over a recent model-based active exploration (MAX)
algorithm, by focusing on the information gain along trajectories instead of
seeking a global exploration policy. A reference implementation of our
algorithm and the conducted experiments is publicly available.

In transition metal perovskites (ABO3) most physical properties are tunable
by structural parameters such as the rotation of the BO6 octahedra. Examples
include the N\'eel temperature of orthoferrites, the conductivity of
mixed-valence manganites, or the band gap of rare-earth scandates. Since oxides
often host large internal electric dipoles and can accommodate heavy elements,
they also emerge as prime candidates to display Rashba spin-orbit coupling,
through which charge and spin currents may be efficiently interconverted.
However, despite a few experimental reports in SrTiO3-based interface systems,
the Rashba interaction has been little studied in these materials, and its
interplay with structural distortions remain unknown. In this Letter, we
identify a bismuth-based perovskite with a giant, electrically-switchable
Rashba interaction whose amplitude can be controlled by both the ferroelectric
polarization and the breathing mode of oxygen octahedra. This particular
structural parameter arises from the strongly covalent nature of the Bi-O
bonds, reminiscent of the situation in perovskite nickelates. Our results not
only provide novel strategies to craft agile spin-charge converters but also
highlight the relevance of covalence as a powerful handle to design emerging
properties in complex oxides.

In 1973 V.L.Popov classified affine SL(2)-embeddings. He proved that a
locally transitive SL(2)-action on a normal affine three-dimensional variety X
is uniquely determined by a pair (p/q, r), where 0<p/q<=1 is an uncancelled
fraction and r is a positive integer. Here r is the order of the stabilizer of
a generic point. In this paper we show that the variety X is toric, i.e. admits
a locally transitive action of an algebraic torus, if and only if r is
divisible by q-p. To do this we prove the following necessary and sufficient
condition for an affine G/H-embedding to be toric. Suppose X is a normal affine
variety, G is a simply connected semisimple algebraic group acting regularly on
X, H is a closed subgroup of G such that the character group $\mathfrak{X}(H)$
is finite and G/H -> X is a dense open equivariant embedding. Then X is toric
if and only if there exist a quasitorus T and a $(G\times T)$-module V such
that $X\stackrel{G}{\cong} V//T$. The key role in the proof plays D. Cox's
construction.

Most of the deployed IEEE 802.11e Wireless Local Area Networks (WLANs) use
infrastructure Basic Service Set (BSS) in which an Access Point (AP) serves as
a gateway between wired and wireless domains. We present the unfairness problem
between the uplink and the downlink flows of any Access Category (AC) in the
802.11e Enhanced Distributed Channel Access (EDCA) when the default settings of
the EDCA parameters are used. We propose a simple analytical model to calculate
the EDCA parameter settings that achieve weighted fair resource allocation for
all uplink and downlink flows. We also propose a simple model-assisted
measurement-based dynamic EDCA parameter adaptation algorithm. Moreover, our
dynamic solution addresses the differences in the transport layer and the
Medium Access Control (MAC) layer interactions of User Datagram Protocol (UDP)
and Transmission Control Protocol (TCP). We show that proposed Contention
Window (CW) and Transmit Opportunity (TXOP) limit adaptation at the AP provides
fair UDP and TCP access between uplink and downlink flows of the same AC while
preserving prioritization among ACs.

My Take: The silliest of the AIRPORT movies, and probably one of the worst of the 70's disaster movies.<br /><br />As if to milk the franchise with all its got, the producers of this third sequel to AIRPORT throws in more action, silly subplots, gratuitous star appearances and goofier elements. In its attempt to be the biggest AIRPORT yet, CONCORDE: AIRPORT '79 is the worst one yet, and probably one of the worst of the disaster movies of the 1970's. With its bad box-office results, it is no wonder that the genre has overstayed its welcome.<br /><br />The film opens with a rather catchy score by Lalo Schifrin backed-up by some impressive shots of the titular aircraft in its former glory (the same plane used in this film would be involved in a crash in July 2000). But then the credits appear, and we get a glimpse of the "all-star" cast, which is composed nothing more of faded Hollywood stars, TV actors and none-too-popular B actors. The plot is sillier than ever: George Kennedy is back in the role of Joe Patroni, now the pilot of the Concorde (co piloted by co-pilot Alain Delon) en route to France after the Summer Olympics. On board is reporter Maggie Whelan (Susan Blakely), who has just discovered that his boyfriend, renowned weapons manufacturer Kevin Harrison (Robert Wagner), is selling their weapons to terrorist. To prevent her from revealing the news to the world, Harrison sends his most advance missiles and best saboteurs to prevent the Concorde from landing.<br /><br />The cast/subplots are dumber than ever, even sillier than an alcoholic Myrna Loy or a singing nun. We have Cicely Tyson transporting a live human heart in a cooler (!), Martha Raye as a woman with a bladder condition (and the character doesn't go deeper than that), J.J. Walker a a pot-smoking saxophonist (arguably the most annoying character in the film), Eddie Albert married to "old" wife Sybil Danning, Avery Schreiber as Russian coach with a deaf daughter and finally, a love story between reporter Jon Davidson and gymnast Andrea Marcovici (much to the sour watching-eye of coach Mercedes McCambidge). Plus the movie gets much closer to LOVE BOAT episode than ever with the silliest cameos of Charo (and her pet Chihuahua) and Bibi Anderson. Camp buffs will no doubt get a real kick-in-the-balls in this silly entry in a long strain of 70's disaster movies. This one is, in more than the sense of the word, a true disaster.<br /><br />Rating: *1/2 out of 5.

Relighting is an essential step in realistically transferring objects from a
captured image into another environment. For example, authentic telepresence in
Augmented Reality requires faces to be displayed and relit consistent with the
observer's scene lighting. We investigate end-to-end deep learning
architectures that both de-light and relight an image of a human face. Our
model decomposes the input image into intrinsic components according to a
diffuse physics-based image formation model. We enable non-diffuse effects
including cast shadows and specular highlights by predicting a residual
correction to the diffuse render. To train and evaluate our model, we collected
a portrait database of 21 subjects with various expressions and poses. Each
sample is captured in a controlled light stage setup with 32 individual light
sources. Our method creates precise and believable relighting results and
generalizes to complex illumination conditions and challenging poses, including
when the subject is not looking straight at the camera.

The term "settler", as used in this context, certainly comes across as pejorative. If it's descriptive, it is often inaccurate; in what manner is someone who was born here, with mixed aboriginal and European ancestry, a settler? Where did such a person come from in order to settle here? No, in this context, the term is used to deny the legitimacy of occupancy to some but not others.

We consider the stochastic heat equation $\partial_{s}u =\frac{1}{2}\Delta u
+(\beta V(s,y)-\lambda)u$, with a smooth space-time stationary Gaussian random
field $V(s,y)$, in dimensions $d\geq 3$, with an initial condition
$u(0,x)=u_0(\varepsilon x)$ and a suitably chosen $\lambda\in{\mathbb R}$. It
is known that, for $\beta$ small enough, the diffusively rescaled solution
$u^{\varepsilon}(t,x)=u(\varepsilon^{-2}t,\varepsilon^{-1}x)$ converges weakly
to a scalar multiple of the solution $\bar u(t,x)$ of the heat equation with an
effective diffusivity $a$, and that fluctuations converge, also in a weak
sense, to the solution of the Edwards-Wilkinson equation with an effective
noise strength $\nu$ and the same effective diffusivity. In this paper, we
derive a pointwise approximation $w^\varepsilon(t,x)=\bar
u(t,x)\Psi^\varepsilon(t,x)+\varepsilon u_1^\varepsilon(t,x)$, where
$\Psi^\varepsilon(t,x)=\Psi(t/\varepsilon^2,x/\varepsilon)$, $\Psi$ is a
solution of the SHE with constant initial conditions, and $u^\varepsilon_1$ is
an explicit corrector. We show that $\Psi(t,x)$ converges to a stationary
process $\tilde \Psi(t,x)$ as $t\to\infty$, that
$\mathbf{E}|u^\varepsilon(t,x)-w^\varepsilon(t, x)|^2$ converges pointwise to
$0$ as $\varepsilon\to 0$, and that
$\varepsilon^{-d/2+1}(u^\varepsilon-w^\varepsilon)$ converges weakly to $0$ for
fixed $t$. As a consequence, we derive new representations of the diffusivity
$a$ and effective noise strength $\nu$. Our approach uses a Markov chain in the
space of trajectories introduced in Gu, Ryzhik, and Zeitouni, "The
Edwards-Wilkinson limit of the random heat equation in dimensions three and
higher," as well as tools from homogenization theory. The corrector
$u_1^\varepsilon(t,x)$ is constructed using a seemingly new approximation
scheme on a mesoscopic time scale.

Slow read
This is a good mystery, but it moves slowly; to the point of being boring at times. There is way too much discussing the evidence they have, what they think, what they are missing, what they don't know, etc. It is repeated over and over. However, I was totally surprised as to the identity of the killer. I totally missed what clued Dusty into the evidence. I guess after hearing the same thing more than once, I just kind of skipped over the info. The mystery is good, just too much filler.

Problems involving approximation from scattered data where data is arranged
quasi-uniformly have been treated by RBF methods for decades. Treating data
with spatially varying density has not been investigated with the same
intensity, and is far less well understood. In this article we consider the
stability of surface spline interpolation (a popular type of RBF interpolation)
for data with nonuniform arrangements. Using techniques similar to those
recently employed by Hangelbroek, Narcowich and Ward to demonstrate the
stability of interpolation from quasi-uniform data on manifolds, we show that
surface spline interpolation on R^d is stable, but in a stronger, local sense.
We also obtain pointwise estimates showing that the Lagrange function decays
very rapidly, and at a rate determined by the local spacing of datasites. These
results, in conjunction with a Lebesgue lemma, show that surface spline
interpolation enjoys the same rates of convergence as those of the local
approximation schemes recently developed by DeVore and Ron.

We demonstrate an enhancement of the spin-orbit coupling in silicon (Si) thin
films by doping with bismuth (Bi), a heavy metal, using ion implantation.
Quantum corrections to conductance at low temperature in phosphorous-doped Si
before and after Bi implantation is measured to probe the increase of the
spin-orbit coupling, and a clear modification of magnetoconductance signals is
observed: Bi doping changes magnetoconductance from weak localization to the
crossover between weak localization and weak antilocalization. The elastic
diffusion length, phase coherence length and spin-orbit coupling length in Si
with and without Bi implantation are estimated, and the spin-orbit coupling
length after the Bi doping becomes the same order of magnitude (Lso = 54 nm)
with the phase coherence length (L{\phi} = 35 nm) at 2 K. This is an
experimental proof that the spin-orbit coupling strength in Si thin film is
tunable by doping with heavy metals.

This paper pursues the study carried out by the authors in "Stability and
Hopf bifurcation in a hexagonal governor system", focusing on the codimension
one Hopf bifurcations in the hexagonal Watt governor differential system. Here
are studied the codimension two, three and four Hopf bifurcations and the
pertinent Lyapunov stability coefficients and bifurcation diagrams, ilustrating
the number, types and positions of bifurcating small amplitude periodic orbits,
are determined. As a consequence it is found an open region in the parameter
space where two attracting periodic orbits coexist with an attracting
equilibrium point.

This report presents the results of a proposed multi-scale fusion-based
single image de-hazing algorithm, which can also be used for underwater image
enhancement. Furthermore, the algorithm was designed for very fast operation
and minimal run-time. The proposed scheme is the faster than existing
algorithms for both de-hazing and underwater image enhancement and amenable to
digital hardware implementation. Results indicate mostly consistent and good
results for both categories of images when compared with other algorithms from
the literature.

Given a subgraph $H$ of a graph $G$, the induced graph of $H$ is the largest
subgraph of $G$ whose vertex set is the same as that of $H$. Our paper concerns
the induced graphs of the components of $\operatorname{WSF}(G)$, the wired
spanning forest on $G$, and, to a lesser extent, $\operatorname{FSF}(G)$, the
free uniform spanning forest. We show that the induced graph of each component
of $\operatorname{WSF}(\mathbb Z^d$) is almost surely recurrent when $d\ge 8$.
Moreover, the effective resistance between two points on the ray of the tree to
infinity within a component grows linearly when $d\ge9$. For any
vertex-transitive graph $G$, we establish the following resampling property:
Given a vertex $o$ in $G$, let $\mathcal T_o$ be the component of
$\operatorname{WSF}(G)$ containing $o$ and $\overline{\mathcal{T}_o}$ be its
induced graph. Conditioned on $\overline{\mathcal{T}_o}$, the tree $\mathcal
T_o$ is distributed as $\operatorname{WSF}(\overline{\mathcal{T}_o})$. For any
graph $G$, we also show that if $\mathcal T_o$ is the component of
$\operatorname{FSF}(G)$ containing $o$ and $\overline{\mathcal{T}_o}$ is its
induced graph, then conditioned on $\overline{\mathcal{T}_o}$, the tree
$\mathcal T_o$ is distributed as
$\operatorname{FSF}(\overline{\mathcal{T}_o})$.

Using Monte Carlo simulation, we studied the electrical conductivity of
two-dimensional films. The films consisted of a poorly conductive host matrix
and highly conductive rod-like fillers (rods). The rods were of various lengths
fitting a log-normal distribution. They could be aligned along a direction.
Special attention was paid to films having completely aligned rods. The impact
of length dispersity and the extent of rod alignment on the
insulator-to-conductor phase transition was studied. The greater the length
dispersity the smaller the critical concentration. The anisotropy of the
electrical conductivity was more pronounced in the vicinity of the phase
transition. A finite size effect was found to be significant only in the
vicinity of the phase transition.

Lunar laser ranging analysis, as regularly performed in the solar system
barycentric frame, requires the presence of the gravitomagnetic term in the
equation of motion at the strength predicted by general relativity. The same
term is responsible for the Lense Thirring effect. Any attempt to modify the
strength of the gravitomagnetic interaction would have to do so in a way that
does not destroy the fit to lunar ranging data and other observations.

We study agitated frictional disks in two dimensions with the aim of
developing a scaling theory for their diffusion over time. As a function of the
area fraction $\phi$ and mean-square velocity fluctuations $\langle v^2\rangle$
the mean-square displacement of the disks $\langle d^2\rangle$ spans 4-5 orders
of magnitude. The motion evolves from a subdiffusive form to a complex
diffusive behabvior at long times. The statistics of $\langle d^n\rangle$ at
all times are multiscaling, since the probability distribution function (pdf)
of displacements has very broad wings. Even where a diffusion constant can be
identified it is a complex function of $\phi$ and $\langle v^2\rangle$. By
identifying the relevant length and time scales and their interdependence one
can rescale the data for the mean square displacement and the pdf of
displacements into collapsed scaling functions for all $\phi$ and $\langle
v^2\rangle$. These scaling functions provide a predictive tool, allowing to
infer from one set of measurements (at a given $\phi$ and $\langle v^2\rangle$)
what are the expected results at any value of $\phi$ and $\langle v^2\rangle$.

The resonant elements that grant metamaterials their unique properties have
the fundamental limitation of restricting their useable frequency bandwidth.
The development of frequency-agile metamaterials has helped to alleviate these
bandwidth restrictions by allowing real-time tuning of the metamaterial
frequency response. We demonstrate electrically-controlled persistent frequency
tuning of a metamaterial, allowing lasting modification of its response using a
transient stimulus. This work demonstrates a form of memory capacitance which
interfaces metamaterials with a class of devices known collectively as memory
devices.

Cheap switches - Several are either sticking or responding differently after only 5 months
It's only been 5 months with this keyboard with low to moderate use during that time. There are already two keys/switches that are starting to stick. It doesn't make it impossible to type, but it is very frustrating. In addition, my first impression of the keyboard was meh. The overall build quality seemed good - I liked the metal top of the keyboard. However, the feeling of the keys has just always been cheap. It is also very easy for the keys to come off of the switches and can sometimes be problematic during gaming or typing. For what it's worth, I bought a Code TKL mechanical keyboard for work at roughly the same time as this Corsair. The Code keyboard gets used at least 10x more than this keyboard has and is standing up just fine and feels way more solid.

We constrain the rest-frame FUV (1546\AA), NUV (2345\AA) and U-band (3690\AA)
luminosity functions (LFs) and luminosity densities (LDs) with unprecedented
precision from $z\sim0.2$ to $z\sim3$ (FUV, NUV) and $z\sim2$ (U-band). Our
sample of over 4.3 million galaxies, selected from the CFHT Large Area $U$-band
Deep Survey (CLAUDS) and HyperSuprime-Cam Subaru Strategic Program (HSC-SSP)
data lets us probe the very faint regime (down to
$M_\mathrm{FUV},M_\mathrm{NUV},M_\mathrm{U} \simeq -15$ at low redshift) while
simultaneously detecting very rare galaxies at the bright end down to comoving
densities $<10^{-5}$ Mpc$^{-3}$. Our FUV and NUV LFs are well fitted by single
Schechter functions, with faint-end slopes that are very stable up to $z\sim2$.
We confirm, but self-consistently and with much better precision than previous
studies, that the LDs at all three wavelengths increase rapidly with lookback
time to $z\sim1$, and then much more slowly at $1<z<2$--$3$. Evolution of the
FUV and NUV LFs and LDs at $z<1$ is driven almost entirely by the fading of the
characteristic magnitude, $M^\star_{UV}$, while at $z>1$ it is due to the
evolution of both $M^\star_{UV}$ and the characteristic number density
$\phi^\star_{UV}$. In contrast, the U-band LF has an excess of faint galaxies
and is fitted with a double-Schechter form; $M^\star_\mathrm{U}$, both
$\phi^\star_\mathrm{U}$ components, and the bright-end slope evolve throughout
$0.2<z<2$, while the faint-end slope is constant over at least the measurable
$0.05<z<0.6$. We present tables of our Schechter parameters and LD measurements
that can be used for testing theoretical galaxy evolution models and
forecasting future observations.

Several observational pieces of evidence indicate that specific evolutionary
channels which involve Roche lobe overflow are not correctly accounted for by
the classical Roche model. We generalize the concept of Roche lobe in the
presence of extra forces (caused by radiation pressure or pulsations). By
computing the distortion of the equipotential surfaces, we are able to evaluate
the impact of these perturbing forces on the stability of Roche-lobe overflow
(RLOF). Radiative forces are parametrized through the constant reduction factor
that they impose on the gravitational force from the radiating star (neglecting
any shielding in case of large optical thickness). Forces imparted by
pulsations are derived from the velocity profile of the wind that they trigger.
We provide analytical expressions to compute the generalized Roche radius.
Depending on the extra force, the Roche-lobe radius may either stay unchanged,
become smaller, or even become meaningless (in the presence of a radiatively-
or pulsation-driven wind). There is little impact on the RLOF stability.

To a torus T over a local field F and a subset of its character module
subject to certain properties, we associate a canonical double cover of the
topological group T(F). We further associate an L-group to this double cover
and establish a natural bijection between L-parameters valued in this L-group
and genuine characters of the double cover. When T is a maximal torus of a
connected reductive group G, we show that there is a canonical L-embedding from
the L-group of the double cover of T to the L-group of G. This leads to a
canonical factorization of Langlands parameters. We associate to a genuine
character of the double cover subject to certain conditions a Harish-Chandra
character formula and use it to give a conjectural characterization of the
supercuspidal local Langlands correspondence for G, subject to a certain
condition on p. This generalizes previous work of Adams and Vogan F=R, and
reinterprets computations of Langlands and Shelstad.

Weak magnetic monopoles with a continuum of charges less than the minimum
implied by Dirac's quantization condition may be possible in non-associative
quantum mechanics. If a weakly magnetically charged proton in a hydrogen atom
perturbs the standard energy spectrum only slightly, magnetic charges could
have escaped detection. Testing this hypothesis requires entirely new methods
to compute energy spectra in non-associative quantum mechanics. Such methods
are presented here, and evaluated for upper bounds on the magnetic charge of
elementary particles.

When Marlene Dietrich was labeled box office poison in 1938 one of a handful of actresses so named by the trades papers, it was films like The Garden Of Allah. How a film could be so breathtakingly beautiful to behold and be so insipidly dull is beyond me. Also how Marlene if she was trying to expand her range and not play a sexpot got stuck with such an old fashioned story is beyond me.<br /><br />The Garden Of Allah, one of the very first films in modern technicolor was a novel set at the turn of the last century by Robert Hitchens who then collaborated on a play adaption with Mary Anderson that ran for 241 performances in 1911-12. It then got two silent screen adaptions. The story is about a monk who runs away from the monastery out in French Tunisia to see some of what he's missed in the world. He runs into a similarly sheltered woman who was unmarried and spent her prime years caring for a sick parent. She's traveling now in the desert and the two meet on a train.<br /><br />The woman is of course Marlene and the runaway monk is Charles Boyer. I'm not sure what was in David O. Selznick's mind in filming this story. Someone like Ingrid Bergman might have made it palatable for the audience. But you can bet that the movie-going public of 1936 when they plunked their money down for a ticket they expected to see Marlene as a modern day Salome rather than a saint with that title. The public still remembered Rudolph Valentino and you can bet that it was some desert romance and seduction that they were expecting.<br /><br />As for the monks you have to remember that they are self supporting in their monasteries and this particular one bottles a special wine of which Boyer happens to be the one with the secret. The monastery will have to rethink it's economics if Boyer leaves. The monks are a sincerely pious group, but from the head man Charles Waldron on down they've a right to be a little concerned with some self interest.<br /><br />Anyway a whole lot of religious platitudes get said here by a pair of leads that really are not suited for the parts. Most especially Marlene Dietrich. I would watch this film with an eye for the special color desert cinematography and forget the plot.

Mr Tamura, I invite you to consult the books the professor lists at the end of his column. Your isolated examples do not refute his overall thesis. What we call the "settlement" of the American West depended on government assistance to a far greater degree than is acknowledged by present-day westerners (and Alaskans) who cling to a myth of individualism. This myopic view of history serves us poorly when we pretend we don't need the guv'ment in our lives because we never did before.

This was one of the lamest movies we watched in the last few months with a predictable plot line and pretty bad acting (mainly from the supporting characters). The interview with Hugh Laurie on the DVD was actually more rewarding than the film itself...<br /><br />Hugh Laurie obviously put a lot of effort into learning how to dance the Samba but the scope of his character only required that he immerse himself at the kiddie end of the pool. The movie is based on the appearance of a lovely girl and great music but these are not sufficient to make good entertainment.<br /><br />If you have never seen Rio, or the inside of a British bank, this film is for you. 2 out of 10.

In this paper, multiwavelength observations of remote coronal dimmings
related to an M1.1 circular-ribbon flare (CRF) in active region (AR) 12434 are
reported. The confined flare without a CME was observed by AIA and HMI on board
SDO on 2015 October 16. Global three-dimensional (3D) magnetic fields before
flare were obtained using the potential field source surface modeling. A few
minutes before the flare hard X-ray peak time (06:13:48 UT), small-scale, weak
dimming appeared $\sim$240$\arcsec$ away from the flare site, which can be
observed by AIA only in 131 and 171 {\AA}. Afterwards, long and narrow dimmings
became evident in all AIA EUV passbands except 304 {\AA}, while localized core
dimming was not clearly observed near the flare site. The large-area dimmings
extended southeastward and the areas increased gradually. The total area of
dimmings reaches (1.2$\pm0.4$)$\times$10$^4$ Mm$^2$ in 193 {\AA}. The maximal
relative intensity decreases in 171 and 193 {\AA} reach 90\% and 80\%,
respectively. Subsequently, the dimmings began to replenish and the area
decreased slowly, lasting for $\geq$3 hr. The remote dimmings and AR 12434 were
connected by large-scale coronal loops. The remote dimmings were associated
with the southwest footpoints of coronal loops with weak negative polarities.
Possible origins of remote dimmings are discussed.

We measure higher partial wave Feshbach resonances in an ultracold mixture of
fermionic $^6$Li and bosonic $^{133}$Cs by magnetic field dependent atom-loss
spectroscopy. For the $p$-wave Feshbach resonances we observe triplet
structures corresponding to different projections of the pair rotation angular
momentum onto the external magnetic field axis.
We attribute the splittings to the spin-spin and spin-rotation couplings by
modelling the observation using a full coupled-channel calculation. Comparison
with an oversimplified model, estimating the spin-rotation coupling by
describing the weakly bound close-channel molecular state with the perturbative
multipole expansion, reveals the significant contribution of the molecular
wavefunction at short internuclear distances. Our findings highlight the
potential of Feshbach resonances in providing precise information on short- and
intermediate-range molecular couplings and wavefunctions. The observed $d$-wave
Feshbach resonances allow us to refine the LiCs singlet and triplet
ground-state molecular potential curves at large internuclear separations.

"Gespenster" Question of to be cool in the German cinema<br /><br />There are not many German films in the last ten years, who have made me so interest. Yes, the problem of the most German films are in this film "Gespenster" too. He is on some places to uncooked to be good to see. Special the figure of Toni (Sabine Timento) is too cool. But thats is in German films always so. Everybody must to learns this coolneß - is the realism in this films. Thats difficult to understand. But in this case it makes some sense, because she steals and she lies - she is the kind of girl is better you never love it, because you lose it. Thats not clear for the other girl Nina in this film. She love her - and she would lose her. But Nina lost everything. She will play with soft emotion and a sad feeling. There is no way - but you must take it said Herbert Achterbusch for twenty years. Thats so often the way it goes in German films. Why? Nina (Julia Hummer) is not inside of the laws of society - the is outside - and there she have no chance. This films tries not on every place to gave her a part inside. Thats one of the problems - the stupid break with conventions - the criminal fascination. Throw it all away - and go nowhere! But the actress plays this difficult part very interesting. On the other side - there the parents - who are the pendant to the two girls. The have a car - a hotel suite - the have money and live in world with music of the opera. But the film stand always in some distance to seem. There is no much explaining of them.<br /><br />In the center of this film, there is one scene you will never forget. The two girls got to a casting. And there they should say how they find together. In this scene Toni will lying on. She said a fantastic story-has nothing to do with her. And then Nina will say the truth. She said it in an introversion way. There is no exhibition in it. She looks to the bottom and said what will happened for here. Thats a great moment. In the next scene on the party with pictures in red this feeling is going on- than Toni goes away...<br /><br />Okay, The film will end - in the German way of coolneß - rubbish - here the circle of sadness is closing. But there was a moment - where is happening something else - and this moment was important. He is more than German coolneß - and this moments are rare in the German cinema in this time!

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

Was fun while it lasted, but had to return it.
Had to return it after the second week since the front propellers didn't work properly, but they will give you a full refund if that happens so long as your return it in a timely manner. Otherwise, the camera on it is about what you'd expect for a $35 drone, and it lasts for about 10 minutes or so (for realistic use, not in sustained flight).

*Update* Decent for a little extra oomph!
Fit my needs well. Decent sound from a very thin form factor. I went a bit overkill on purchasing a separate wiring kit, but no issues on the setup. *Update* Don't bother with leaving a review for a free t-shirt (per decal instructions on box). After giving me the runaround, they said it was only for purchases made through their website. If that's customer service, I don't want it.

We examine the relationship between superoutburst duration $t_{\rm
dur}$ and orbital period $P_{\rm orb}$ in AM CVn ultra-compact binary
systems. We show that the previously determined steep relation derived by
Levitan et al (2015) was strongly influenced by the inclusion of upper limits
for systems with a relatively long orbital period in their fit. Excluding the
upper limit values and including $t_{\rm dur}$ values for three systems at long
$P_{\rm orb}$ which were not considered previously, then $d \log (t_{\rm dur})/
d \log (P_{\rm orb})$ is flat as predicted by Cannizzo & Nelemans(2015)

Higgs algebras are used to construct rotational Hamiltonians. The
correspondence between the spectrum of a triaxial rotor and the spectrum of a
cubic Higgs algebra is demonstrated. It is shown that a suitable choice of the
parameters of the polynomial algebra allows for a precise identification of
rotational properties. The harmonic limit is obtained by a contraction of the
algebra, leading to a linear symmetry.

Some fractional quantum Hall states observed in experiments may be described
by first-quantized wavefunctions with special clustering properties like the
Moore-Read Pfaffian for filling factor nu = 5/2. This wavefunction has been
constructed by constructing correlation functions of a two-dimensional
conformal field theory (CFT) involving a free boson and a Majorana fermion. By
considering other CFTs many other clustered states have been proposed as
candidate FQH states under appropriate circumstances. It is believed that the
underlying CFT should be unitary if one wants to describe an incompressible
i.e. gapped liquid state. We show that by changing the way one derives the
wavefunction from its parent CFT it is possible to obtain an incompressible
candidate state when starting from a non-unitary parent. The construction
mimics a global change of parameters in the phase space of the electron system.
We explicit our construction in the case of the so-called Gaffnian state (a
state for filling factor 2/5) and also for the Haldane-Rezayi state (a
spin-singlet state at filling 1/2).

We show that the Glauber dynamics on proper 9-colourings of the triangular
lattice is rapidly mixing, which allows for efficient sampling. Consequently,
there is a fully polynomial randomised approximation scheme (FPRAS) for
counting proper 9-colourings of the triangular lattice. Proper colourings
correspond to configurations in the zero-temperature anti-ferromagnetic Potts
model. We show that the spin system consisting of proper 9-colourings of the
triangular lattice has strong spatial mixing. This implies that there is a
unique infinite-volume Gibbs distribution, which is an important property
studied in statistical physics. Our results build on previous work by Goldberg,
Martin and Paterson, who showed similar results for 10 colours on the
triangular lattice. Their work was preceded by Salas and Sokal's 11-colour
result. Both proofs rely on computational assistance, and so does our 9-colour
proof. We have used a randomised heuristic to guide us towards rigourous
results.

Various aspects of the connection between cloud cover (CC) and cosmic rays
(CR) are analysed. We argue that the anticorrelation between the temporal
behaviour of low (LCC) and middle (MCC) clouds evidences against causal
connection between them and CR. Nevertheless, if a part of low clouds (LCC) is
connected and varies with CR, then its most likely value averaged over the
Globe should not exceed 20% at the two standard deviation level.

We use isoperimetric inequalities combined with a new technique to prove
upper bounds for the site percolation threshold of plane graphs with given
minimum degree conditions. In the process we prove tight new isoperimetric
bounds for certain classes of hyperbolic graphs. This establishes the vertex
isoperimetric constant for all triangular and square hyperbolic lattices,
answering a question of Lyons and Peres.
We prove that plane graphs of minimum degree at least $7$ have site
percolation threshold bounded away from $1/2$, which was conjectured by
Benjamini and Schramm, and make progress on a conjecture of Angel, Benjamini
and Horesh that the critical probability is at most $1/2$ for plane
triangulations of minimum degree $6$. We prove additional bounds for stronger
minimum degree conditions, and for graphs without triangular faces.

In this paper we define and study generalized Atiyah classes for quasi
coherent sheaves relative to arbitrary morphisms of schemes. We use derivations
and quasi coherent sheaves of left and right O-modules to define a generalized
first order jet bundle J(E) and a generalized Atiyah sequence for E. The
generalized jet bundle J(E) is a left and right module over a sheaf J of
associative rings on X. The sheaf J is an extension of O with a sheaf I of two
sided ideals of square zero. The Atiyah sequence gives rise to a generalized
Atiyah class c(E) with the property that c(E)=0 if and only if the left
structure on J(E) is O-isomorphic to the right structure on J(E). We give
examples where c(E)=0 and c(E)\neq 0 hence the class c(E) is a non trivial
characteristic class.

We summarize recent developments in the use of spectral methods for analyzing
large numbers of orbits in N-body simulations to obtain insights into the
global phase space structure of dark matter halos. The fundamental frequencies
of oscillation of orbits can be used to understand the physical mechanism by
which the shapes of dark matter halos evolve in response to the growth of
central baryonic components. Halos change shape primarily because individual
orbits change their shapes adiabatically in response to the growth of a
baryonic component, with those at small radii become preferentially rounder.
Chaotic scattering of orbits occurs only when the central point mass is very
compact and is equally effective for centrophobic long-axis tube orbits as it
is for centrophilic box orbits.

The rapid development of autonomous driving in recent years presents lots of
challenges for scene understanding. As an essential step towards scene
understanding, semantic segmentation thus received lots of attention in past
few years. Although deep learning based state-of-the-arts have achieved great
success in improving the segmentation accuracy, most of them suffer from an
inefficiency problem and can hardly applied to practical applications. In this
paper, we systematically analyze the computation cost of Convolutional Neural
Network(CNN) and found that the inefficiency of CNN is mainly caused by its
wide structure rather than the deep structure. In addition, the success of
pruning based model compression methods proved that there are many redundant
channels in CNN. Thus, we designed a very narrow while deep backbone network to
improve the efficiency of semantic segmentation. By casting our network to
FCN32 segmentation architecture, the basic structure of most segmentation
methods, we achieved 60.6\% mIoU on Cityscape val dataset with 54 frame per
seconds(FPS) on $1024\times2048$ inputs, which already outperforms one of the
earliest real time deep learning based segmentation methods: ENet.

Easy to use
This made it easy to install an aftermarket radio. I was able to solder up all the connections on my workbench and professionally shrink tube all the connections. Once this was all done it was as simple as mating the connectors together. Wiring color codes on the back made it very easy to map all the wires to new stereo.

President Donald Trump and North Korean leader Kim Jong-un stand on the South Korean side of the Demilitarized Zone between North and South Korea on June 30, 2019. (Erin Schaff/The New York Times)
SEOUL, South Korea — North Korea’s leader, Kim Jong Un, has long threatened to “find a new way” if the United States persists with sanctions. And when North Korea announced his “revolutionary” new way Wednesday, the strategy revealed both a defiance and a deep caution in confronting President Donald Trump.
Kim vowed, in a lengthy policy statement, to expand his country’s nuclear force, making vague threats to show off a “new strategic weapon” in the near future and “shift to a shocking actual action.” He warned that North Korea would not be bound by a self-imposed moratorium on nuclear and long-range ballistic missile tests.
But he also moderated those threats by leaving out the specifics. Kim did not explicitly say that he was formally lifting the test moratorium or that he was terminating diplomacy. Instead, he said his efforts to expand his nuclear weapons capabilities could be adjusted “depending on the U.S. future attitude.”
It’s a wait-and-see approach that leaves room for more negotiations.
Analysts say that Kim is making a calculation against the backdrop of the political uncertainty in the United States, where Trump faces both a Senate impeachment trial and an election. The North Korean leader, they said, does not necessarily want to rush to strike a deal that could be overturned if Trump does not win a second term.
“Kim Jong Un continues to hedge his bets,” said Jean H. Lee, a North Korea expert at the Woodrow Wilson International Center for Scholars in Washington. “I think we’ll see Kim continue to find ways to provoke Washington as a way to gain the upper hand in future nuclear negotiations without directly challenging President Trump.”
As he waits, Kim can continue to play the role of tough guy, increasing the stakes in his nuclear brinkmanship. North Korea can expand its nuclear arsenal, produce more bomb fuel, build more nuclear warheads and improve its missile capabilities.
Less predictable is whether or when Kim might deliver an infuriating message to Trump by testing a nuclear weapon or intercontinental ballistic missile.
Such a test could precipitate another “fire and fury” response from Trump. When Kim last conducted such tests, in 2017, Trump threatened to “totally destroy North Korea,” inciting fears of possible war.
Tensions eased after North Korea declared a test moratorium in April 2018. And after Trump met with Kim in Singapore later that year, the president said the two “fell in love.”
That moratorium remains the best outcome Trump can cite from his on-and-off diplomacy with Kim — one that the North Korean leader may be wary of yanking away too soon.
By treading carefully, Pyongyang also avoids more economic pain. Launching a long-range missile would set off another round of United Nations sanctions, and such tests could also provoke China and Russia at a time when Kim strongly needs their help to blunt the pain of current internationals measures.
Those sanctions required China, Russia and other countries to send North Korean workers home by late last month, depriving Kim’s government of a key source of hard currency. North Korea also increasingly depends on Chinese tourists as an alternative source of income, and Kim has recently built a number of tourist zones to attract them.
In his policy report this week, Kim acknowledged that his country’s efforts at economic reform faced “grave problems” and were “not making visible progress,” according to the state news media. He also reported “evil practices and stagnation” in key industries and criticized his economic officials for “merely shouting the slogan of self-reliance” while lacking leadership and “responsibility” to revamp the economy.
Kim also indicated that he was preparing for a “protracted” standoff with Washington, exhorting North Koreans to accept it as “a fait accompli that we have to live under the sanctions.” After 18 months of faltering diplomacy, he said he was convinced that his country should stick to “self-reliance” rather than embracing the “brilliant transformation” of its economy that Trump promised if Pyongyang abandoned its nuclear weapons.
Kim also called on his people “never to barter the security and dignity” that the North’s nuclear deterrent provided, “even though we tighten our belts.”

This paper extends the Spatial-Temporal Graph Convolutional Network (ST-GCN)
for skeleton-based action recognition by introducing two novel modules, namely,
the Graph Vertex Feature Encoder (GVFE) and the Dilated Hierarchical Temporal
Convolutional Network (DH-TCN). On the one hand, the GVFE module learns
appropriate vertex features for action recognition by encoding raw skeleton
data into a new feature space. On the other hand, the DH-TCN module is capable
of capturing both short-term and long-term temporal dependencies using a
hierarchical dilated convolutional network. Experiments have been conducted on
the challenging NTU RGB-D-60 and NTU RGB-D 120 datasets. The obtained results
show that our method competes with state-of-the-art approaches while using a
smaller number of layers and parameters; thus reducing the required training
time and memory.

Observations of circumstellar disks provide a powerful tool for our
understanding of planetary systems dynamics. Analogs to the Solar System
asteroid belts, debris disks result from the collision of the remaining solid
material of the planet formation process. Even if the presence of disk is now
reported for hundreds of stars, its detection around stars similar to the Sun
is still very sparse. We report the results of a search for debris disks around
Kepler stars with surface physical parameters close to solar values, including
rotation period, using observations by the Wide-field infrared Survey Explorer
(WISE). From the entire sample of Kepler stars, 881 targets were identified
with these parameters and only six of them (KIC 1868785, 7267949, 7435796,
10533222, 11352643, and KIC 11666436) show unambiguous infrared excess, for
which we determined debris disk physical parameters. Interestingly, the present
study reveals traces of debris disks much more massive and brighter than the
Solar System zodiacal dust, probably resulting from recent violent collisional
events, orbiting stars with ages around the solar values.

Recommender Systems have not been explored to a great extent for improving
health and subjective wellbeing. Recent advances in mobile technologies and
user modelling present the opportunity for delivering such systems, however the
key issue is understanding the drivers of subjective wellbeing at an individual
level. In this paper we propose a novel approach for deriving personalized
activity recommendations to improve subjective wellbeing by maximizing the
congruence between activities and personality traits. To evaluate the model, we
leveraged a rich dataset collected in a smartphone study, which contains three
weeks of daily activity probes, the Big-Five personality questionnaire and
subjective wellbeing surveys. We show that the model correctly infers a range
of activities that are 'good' or 'bad' (i.e. that are positively or negatively
related to subjective wellbeing) for a given user and that the derived
recommendations greatly match outcomes in the real-world.

... why watch a TV drama (billed as a comedy) in which none of the characters are likable or even interesting people ? I can sort of see what the writer David Renwick was trying to achieve: the misdirections and bad-taste surprises that he put into "One foot in the grave", etc. I admit that the script made a bit more of an effort than most on British TV at the moment. But really ... who cares about these people ? They are cold bores.<br /><br />Another poster mentioned the scene in which the woman sits down to watch a video of herself and her deceased ex-boyfriend shagging. That was the moment when I switched OFF this programme, never to return.<br /><br />P.S. It's interesting to note that the posters who didn't like this series are all British, whereas those who praise it are mostly in other countries. This reflects the fact that when the BBC broadcast this series it was ignored by viewers and sank like a stone.<br /><br />P.P.S. Good news for those who liked it ! There will be a second series in Autumn 2007 - though without the male lead. It sounds like the BBC have decided to turn it into a more conventional 30 minute sitcom.

We study the orbitally frustrated singlet-triplet models that emerge in the
context of spin-orbit coupled Mott insulators with $t_{2g}^4$ electronic
configuration. In these compounds, low-energy magnetic degrees of freedom can
be cast in terms of three-flavor "triplon" operators describing the transitions
between spin-orbit entangled $J=0$ ionic ground state and excited $J=1$ levels.
In contrast to a conventional, flavor-isotropic O(3) singlet-triplet models,
spin-orbit entangled triplon interactions are flavor-and-bond selective and
thus highly frustrated. In a honeycomb lattice, we find close analogies with
the Kitaev spin model -- an infinite number of conserved quantities, no
magnetic condensation, and spin correlations being strictly short-ranged.
However, due to the bosonic nature of triplons, there are no emergent gapless
excitations within the spin gap, and ground state is a strongly correlated
paramagnet of dense triplon pairs with no long-range entanglement. Using exact
diagonalization, we study the bosonic Kitaev model and its various extensions,
which break exact symmetries of the model and allow magnetic condensation of
triplons. Possible implications for magnetism of ruthenium oxides are
discussed.

You see Brian, you are making assumptions about me and decided to paint me into something you can compute. You know nothing about me, so it's interesting that you can group me. The thing is, I've agreed with some Wente columns and I've agreed with some Renzetti columns. Can you say the same thing?

1 hour and 40 minutes of talking--boring talking, and more talking and then some. It is hard for me to grasp how an actress like Anne Parillaud, who shone superbly in Femme Fatale, would sign up for such a piece of crap! Unbelievable. If you need a nightcap, this movie might help, although I would prefer some nice classical music. unfortunately, i just found out that i have to write 10 lines for my comment to appear--that's almost as unbelievable! so, short and succinct one or two sentence commentaries expressing one's core take on a movie is not enough. geez, people. i made my point and don't to waste your time with more, unnecessary words--as this movie does.

I saw this at a screening last night too. I was totally blown away at how much better this movie was than what I expected. Not many movies can combine dark comedy and current event drama and not have it fall apart in the conclusion.<br /><br />I won't bother rehashing the plot too much because I think the less you know about this movie going into it makes it that much better. But I will say that Adam Sandler's performance was really refreshing and real. He was funny, and much funnier than most of his most recent comedies. Don Cheadle was believable as always.<br /><br />This movie isn't funny like Borat or Billy Madison but it has a good pace about it. I'd say 90% of the audience laughed for most of the film. Midway through the movie slows down to address the drama end of things and does a really nice job of tying it all together.<br /><br />I also thought it was really cool how instead of playing up the whole black friend/white friend thing they chose to just ignore it and focus on the relationships themselves.

We study the origin of the supersymmetry breaking induced by the mediation of
gravity and the radion multiplet from the hidden to the visible brane in the
context of the N=2, D=5 supergravity compactified on S_1/Z_2 orbifolds. The
soft supersymmetry breaking terms for scalar masses, trilinear scalar couplings
and gaugino masses are calculated to leading order in the five dimensional
Newton's constant k_5^2 and the gravitino mass m_{3/2}. These are finite and
non-vanishing, with the scalar soft masses be non-tachyonic, and are all
expressed in terms of the gravitino mass and the length scale R of the fifth
dimension. The soft supersymmetry breaking parameters are thus correlated and
the phenomenological implications are discussed.

We study an extension of quasi-single field model of inflation containing
multiple semi-heavy isocurvaton fields using the Schwinger-Keldysh mechanism.
We calculate the amplitudes and the shapes of the bispectrum and the
trispectrum. We show that the diagrammatic approach associated with the
Schwinger-Keldysh mechanism simplifies the analysis considerably compared to
standard in-in formalism. This method is helpful to study the spectroscopy of
masses and couplings of light and semi-heavy fields during inflation.

We prove an inequality relating the trace of the extrinsic curvature, the
total angular momentum, the centre of mass, and the Trautman-Bondi mass for a
class of gravitational initial data sets with constant mean curvature extending
to null infinity. As an application we obtain non-existence results for the
asymptotic Dirichlet problem for CMC hypersurfaces in stationary space-times.

The issue of fairness in machine learning models has recently attracted a lot
of attention as ensuring it will ensure continued confidence of the general
public in the deployment of machine learning systems. We focus on mitigating
the harm incurred by a biased machine learning system that offers better
outputs (e.g. loans, job interviews) for certain groups than for others. We
show that bias in the output can naturally be controlled in probabilistic
models by introducing a latent target output. This formulation has several
advantages: first, it is a unified framework for several notions of group
fairness such as Demographic Parity and Equality of Opportunity; second, it is
expressed as a marginalisation instead of a constrained problem; and third, it
allows the encoding of our knowledge of what unbiased outputs should be.
Practically, the second allows us to avoid unstable constrained optimisation
procedures and to reuse off-the-shelf toolboxes. The latter translates to the
ability to control the level of fairness by directly varying fairness target
rates. In contrast, existing approaches rely on intermediate, arguably
unintuitive, control parameters such as covariance thresholds.

The treatment effect in a specific subgroup is often of interest in
randomized clinical trials. When the subgroup is characterized by the absence
of certain post-randomization events, a naive analysis on the subset of
patients without these events may be misleading. The principal stratification
framework allows one to define an appropriate causal estimand in such settings.
Statistical inference for the principal stratum estimand hinges on
scientifically justified assumptions, which can be included with Bayesian
methods through prior distributions. Our motivating example is a large
randomized placebo-controlled trial of siponimod in patients with secondary
progressive multiple sclerosis. The primary objective of this trial was to
demonstrate the efficacy of siponimod relative to placebo in delaying
disability progression for the whole study population. However, the treatment
effect in the subgroup of patients who would not relapse during the trial is
relevant from both a scientific and regulatory perspective. Assessing this
subgroup treatment effect is challenging as there is strong evidence that
siponimod reduces relapses. Aligned with the draft regulatory guidance ICH
E9(R1), we describe in detail the scientific question of interest, the
principal stratum estimand, the corresponding analysis method for binary
endpoints and sensitivity analyses.

Having a nightmare that you've gone to work with no trousers on is a common anxiety dream, but it turned into reality for one unfortunate man whose father promptly shared his embarrassing wardrobe malfunction on Twitter.
The dad, who doesn't disclose his identity on social media, going by 'Hold My Beer,' shared a text conversation he had with his son, Zach, from Florida, who admitted to ripping his pants at work in front of a coworker.
The incident was made worse because Zach, who works as a waiter, wasn't wearing any underwear due to it being 'laundry day,' and his female manager Kelly happened to walk past him when the pants ripped and witnessed the whole thing.
Instead of keeping the hilarious but unfortunate event to himself, the father decided to publish their hilarious exchange on Twitter, leading the embarrassing story to go viral.
Zach, a waiter from Florida, told his dad his pants ripped while he was at work. The incident was made worse by the fact he wasn't wearing any underwear
Zach told his father that his manager, Kelly, was putting some bowls away and saw all of his anatomy when the pants ripped
Zach told his father that the incident was the 'most embarrassing thing of his f****** life' before getting into the detail of the story.
In brutally honest terms, the son explained to his dad that he thought the trousers were 'a little tight' but fitted him nicely, and still decided to wear them to work.
But tragedy struck as the young waiter squatted down to pick up some bowls, his pants completely ripping apart in front of his manager who was putting soup bowls away.
In candid terms, Zach added that Kelly had seen a very intimate part of his anatomy and 'looked inside of [him]. and that the incident has left him with 'a**less chaps' for pants.
In the hilarious exchange, Zach went on to say he had to go home and change, because his pants looked like 'a**less chaps'
The waiter had to rush home to change and went back into work like a true professional, after his pants 'exploded off' him.
Zach's father shared the conversation on Twitter shortly after his revelations, and after asking permission.
He said Zach 'f****** slays' him and that he had to get him on Twitter.
Zach's father shared their exchange on Twitter with his son's permission, and said he had to get him on Twitter
People loved the hilarious story, saying Zach was their 'hero,' also joking about Kelly, who had seen the whole thing
The exchange quickly went viral, gathering more than 6,600 likes and 900 retweets as people could not get enough of poor Zach's misadventure. .
'Your son just became my hero,' one wrote.
'I think this means he and Kelly are now legally wed,' joked another.
'This is the best thing I've seen today. Zack is MVP of the day,' said one.
'It hurts to laugh this hard,' added another.

"site" the law? or do you mean "cite" the law? For all the readers here, this reeks of suspicion, because of witness accounts and refusal of the pilot to cooperate with FAA/Troopers. I'm thinking there may have been some kind of substance abuse that was a factor in this crash "on-board" the pilot.

In this work, a two dimensional system of polymer grafted nanoparticles is
analyzed using large-scale Langevin Dymanics simulations. Effective
core-softened potentials were obtained for two cases: one where the polymers
are free to rotate around the nanoparticle core and a second where the polymers
are fixed, with a $45^\circ$ angle between them. The use of effective
core-softened potentials allow us to explore the complete system phase space.
In this way, the $PT$, $T\rho$ and $P\rho$ phase diagrams for each potential
were obtained, with all fluid and solid phases. The phase boundaries were
defined analyzing the specific heat at constant pressure, the system mean
square displacement, the radial distribution function and the discontinuities
in the density-pressure phase diagram. Also, due the competition in the system
we have observed the presence of waterlike anomalies, such as the temperature
of maximum density - in addition with a tendency of the TMD to move to lower
temperatures (negative slope)- and the diffusion anomaly. It was observed
different morphologies (stripes, honeycomb, amorphous) for each nanoparticle.
We observed that for the fixed polymers case the waterlike anomalies are
originated by the competition between the potential characteristic length
scales, while for the free to rotate case the anomalies arises due a smaller
region of stability in the phase diagram and no competition between the scales
was observed.

Too LARGE and too SMALL
Crocs Men's Santa Cruz 2 Luxe Loafer: How can it be too large AND too small? The product is poorly designed. It is very difficult to put the shoe on because there is no stretch. (The small elastic band is useless because it is too small and placed badly.) One it is on, it is too large. In part, that could be due to the insole being very thick and collapsing. Overall it was a big disappointment.
