Great set of bathroom rugs!
The rugs are great and the lid cover fits my elongated bowl. The rug for in front of the toilet has an odd shape cutout that doesn’t match my toilet, otherwise I would give this 5 stars. It could just be my situation. I’d buy them again anyway.

Hey mtf:
Did it ever occur to you that the Feds already have your social security number, metadata via the NSA on most of your cell phone calls, have your medical records, your tax returns, work records, driving records,mortgage and financial information and on and on.
So why are you worrying about them checking on your voting records?
Answer: You and your Dem buddies are hiding massive voting fraud.

Most proposed dark matter candidates are stable and are produced thermally in
the early Universe. However, there is also the possibility of unstable (but
long-lived) dark matter, produced thermally or otherwise. We propose a strategy
to distinguish between dark matter annihilation and/or decay in the case that a
clear signal is detected in gamma-ray observations of Milky Way dwarf
spheroidal galaxies with gamma-ray experiments. The sole measurement of the
energy spectrum of an indirect signal would render the discrimination between
these cases impossible. We show that by examining the dependence of the
intensity and energy spectrum on the angular distribution of the emission, the
origin could be identified as decay, annihilation, or both. In addition, once
the type of signal is established, we show how these measurements could help to
extract information about the dark matter properties, including mass,
annihilation cross section, lifetime, dominant annihilation and decay channels,
and the presence of substructure. Although an application of the approach
presented here would likely be feasible with current experiments only for very
optimistic dark matter scenarios, the improved sensitivity of upcoming
experiments could enable this technique to be used to study a wider range of
dark matter models.

In this paper we consider the restriction of a unitary irreducible
representation of type $A_{\mathfrak q}(\lambda)$ of $GL(4,{\mathbb R})$ to
reductive subgroups $H$ which are the fixpoint sets of an involution. We obtain
a formula for the restriction to the symplectic group and to $GL(2,{\mathbb
C})$, and as an application we construct in the last section some
representations in the cuspidal spectrum of the symplectic and the complex
general linear group. In addition to working directly with the cohmologically
induced module to obtain the branching law, we also introduce the useful
concept of pseudo dual pairs of subgroups in a reductive Lie group.

Got the job done on a 2012 Honda Pilot
Worked but barely. I’m not sure why there isn’t a specific cap for the Honda’s but this is supposed to be the universal cure. I just used it with pressure no fluid and it did ok. Just watch the level of the master cylinder closely and add fluid often. Toss the chains, they are useless. I used a c clamp to hold it on.

Automatic image caption generation aims to produce an accurate description of
an image in natural language automatically. However, Bangla, the fifth most
widely spoken language in the world, is lagging considerably in the research
and development of such domain. Besides, while there are many established data
sets to related to image annotation in English, no such resource exists for
Bangla yet. Hence, this paper outlines the development of "Chittron", an
automatic image captioning system in Bangla. Moreover, to address the data set
availability issue, a collection of 16,000 Bangladeshi contextual images has
been accumulated and manually annotated in Bangla. This data set is then used
to train a model which integrates a pre-trained VGG16 image embedding model
with stacked LSTM layers. The model is trained to predict the caption when the
input is an image, one word at a time. The results show that the model has
successfully been able to learn a working language model and to generate
captions of images quite accurately in many cases. The results are evaluated
mainly qualitatively. However, BLEU scores are also reported. It is expected
that a better result can be obtained with a bigger and more varied data set.

Starting from a divergence-free rank-4 tensor of which the trace is the
cosmological Einstein tensor, we give a construction of conserved charges in
Einstein's gravity and its higher derivative extensions for asymptotically
anti-de Sitter spacetimes. The current yielding the charge is explicitly
gauge-invariant, and the charge expression involves the linearized Riemann
tensor at the boundary. Hence, to compute the mass and angular momenta in these
spacetimes, one just needs to compute the linearized Riemann tensor. We give
two examples.

The Mike and Merry Fix are neighbors of ours, living a couple of miles "down the road." They're the very kind of folks you want for friends and neighbors and in your community. Mike recounts their experiences over the last few months and rejects the "fear and loathing" campaign message from Mr. Trump. He shares a positive, uplifting view of the world.
Mr. Trump and his supporters present a very different world: dark, foreboding, and very dangerous. They are promoting a fearful view. Once you believe that promotion, have they ever "got a deal for you." His name is Donald Trump and he's here to save the day.
I hope we can see the sunshine and light of Mr. Fix's comments and reject the dark, cynical world view Mr. Trump presents. Mr. Fix offers us hope and faith in our fellow Americans. Mr. Trump and his followers offer hate, division, mistrust and fear. For me, it's not a difficujlt choice....... regards, Gary

Imitation learning seeks to learn an expert policy from sampled
demonstrations. However, in the real world, it is often difficult to find a
perfect expert and avoiding dangerous behaviors becomes relevant for safety
reasons. We present the idea of \textit{learning to avoid}, an objective
opposite to imitation learning in some sense, where an agent learns to avoid a
demonstrator policy given an environment. We define avoidance learning as the
process of optimizing the agent's reward while avoiding dangerous behaviors
given by a demonstrator. In this work we develop a framework of avoidance
learning by defining a suitable objective function for these problems which
involves the \emph{distance} of state occupancy distributions of the expert and
demonstrator policies. We use density estimates for state occupancy measures
and use the aforementioned distance as the reward bonus for avoiding the
demonstrator. We validate our theory with experiments using a wide range of
partially observable environments. Experimental results show that we are able
to improve sample efficiency during training compared to state of the art
policy optimization and safety methods.

PDS 70 is a $\sim$5 Myr old star with a gas and dust disc in which several
proto-planets have been discovered. We present the first UV detection of the
system along with X-ray observations taken with the \textit{Neil Gehrels Swift
Observatory} satellite. PDS 70 has an X-ray flux of 3.4$\times 10^{-13}$ erg
cm$^{-2}$ s$^{-1}$ in the 0.3-10.0 keV range, and UV flux (U band) of
3.5$\times 10^{-13}$ erg cm$^{-2}$ s$^{-1}$ . At the distance of 113.4 pc
determined from Gaia DR2 this gives luminosities of 5.2$\times 10^{29}$ erg
s$^{-1}$ and 5.4$\times 10^{29}$ erg s$^{-1}$ respectively. The X-ray
luminosity is consistent with coronal emission from a rapidly rotating star
close to the log $\frac{L_{\mathrm{X}}}{L_{\mathrm{bol}}} \sim -3$ saturation
limit. We find the UV luminosity is much lower than would be expected if the
star were still accreting disc material and suggest that the observed UV
emission is coronal in origin.

In this article, the structure of semiclassical measures for solutions to the
linear Schr\"{o}dinger equation on the torus is analysed. We show that the
disintegration of such a measure on every invariant lagrangian torus is
absolutely continuous with respect to the Lebesgue measure. We obtain an
expression of the Radon-Nikodym derivative in terms of the sequence of initial
data and show that it satisfies an explicit propagation law. As a consequence,
we also prove an observability inequality, saying that the $L^2$-norm of a
solution on any open subset of the torus controls the full $L^2$-norm.

We present a detailed study of oscillating modes in a slab waveguide with air
core and anisotropic metamaterial cladding. It is shown that, under specific
dielectric configurations, slow and even stopped electromagnetic wave can be
supported by such an air waveguide. We propose a linearly tapped waveguide
structure that could lead the propagating light to a complete standstill. Both
the theoretical analysis and the proposed waveguide have been validated by
full-wave simulation based on finite-difference time-domain method.

We prove the existence of a solution to a singular anisotropic elliptic
equation in a bounded open subset $\Omega$ of $\mathbb R^N$ with $N\ge 2$,
subject to a homogeneous boundary condition: \begin{equation} \label{eq0}
\left\{ \begin{array}{ll} \mathcal A u+ \Phi(u,\nabla u)=\Psi(u,\nabla u)+
\mathfrak{B} u \quad& \mbox{in } \Omega,\\ u=0 & \mbox{on } \partial\Omega.
\end{array} \right. \end{equation} Here $ \mathcal A u=-\sum_{j=1}^N
|\partial_j u|^{p_j-2}\partial_j u$ is the anisotropic
$\overrightarrow{p}$-Laplace operator, while $\mathfrak B$ is an operator from
$W_0^{1,\overrightarrow{p}}(\Omega)$ into $W^{-1,\overrightarrow{p}'}(\Omega)$
satisfying suitable, but general, structural assumptions. $\Phi$ and $\Psi$ are
gradient-dependent nonlinearities whose models are the following:
\begin{equation*} \label{phi}\Phi(u,\nabla u):=\left(\sum_{j=1}^N
\mathfrak{a}_j |\partial_j u|^{p_j}+1\right)|u|^{m-2}u, \quad \Psi(u,\nabla
u):=\frac{1}{u}\sum_{j=1}^N |u|^{\theta_j} |\partial_j u|^{q_j}.
\end{equation*} We suppose throughout that, for every $1\leq j\leq N$,
\begin{equation*}\label{ass} \mathfrak{a}_j\geq 0, \quad \theta_j>0, \quad
0\leq q_j<p_j, \quad 1<p_j,m\quad \mbox{and}\quad p<N, \end{equation*} and we
distinguish two cases: 1) for every $1\leq j\leq N$, we have $\theta_j\geq 1$;
2) there exists $1\leq j\leq N$ such that $\theta_j<1$. In this last situation,
we look for non-negative solutions of \eqref{eq0}.

We propose a model of starburst--driven galactic outflows whose dynamics
depends on both radiation and thermal pressure. Standard models of thermal
pressure--driven winds fail to explain some key observations of outflows at low
and high redshift galaxies. We discuss a scenario in which radiation pressure
from massive stars in a stellar population drive a shell of gas and dust.
Subsequent supernova (SN) explosions from the most massive stars in this
population then drive stellar ejecta outward in a rarefied medium, making it
collide with the radiation pressure driven shell. The collision imparts renewed
momentum to the shell, and the resulting re-acceleration makes the shell
Rayleigh-Taylor unstable, fragmenting the shell. We show that the speed of
these ballistic fragments can explain some recently observed correlations in
Lyman break galaxies between wind speed, reddening and star formation rate.

It is well known that the mere location of a Beat Cepheid model in a Period
Ratio \vs Period diagram (Petersen diagram) puts constraints on its metallicity
Z. But these bounds are sensitive to the mixture of elements that are lumped
into the parameter $Z$. In this short paper we update the previous results that
were based on the Grevesse-Noels solar mixture to the recent, revised Asplund,
Grevesse & Sauval (2005) (AGS) solar mixture.
We also examine the effect of the envelope depth on the accuracy of the
computed pulsation periods. We find that for low period Cepheids with high Z
the customary approximation of envelope pulsation breaks down. It is necessary
to compute stellar models that extend to the center and to include burning and
composition inhomogeneities in the modeling. Fortunately, however, most Beat
Cepheids that have been observed so far seem to avoid that regime.

We reformulate several basic notions of notions in finite group theory in
terms of iterations of the lifting property (orthogonality) with respect to
particular morphisms. Our examples include the notions being nilpotent,
solvable, perfect, torsion-free; p-groups and prime-to-p-groups; Fitting
subgroup, perfect core, p-core, and prime-to-p core. We also reformulate as in
similar terms the conjecture that a localisation of a (transfinitely) nilpotent
group is (transfinitely) nilpotent.

Viewing DE VIERDE MAN (aka THE FOURTH MAN) is a slightly unsettling and rather fascinating experience. It's a very tight and intense psychological mystery/thriller from Netherlands's Paul Verhoeven. He directed this film just before he got big with his "free-ticket to Hollywood"-movie FLESH + BLOOD. In a lot of user-comments on this site I noticed the mentioning of Alfred Hitchcock. Indeed, this movie might very well be Hitchcockian, but I also noticed touches of early Cronenberg (the visceral), flavors of David Lynch (surreal story-linked visuals) and even Roman Polanski (plot-wise set-up). Funny thing is that the movies by those directors I was thinking of while watching DE VIERDE MAN weren't made until after 1983, the year of release of THE FOURTH MAN. So go figure.<br /><br />Very much credit indeed must be given to the story of the original novel by Gerard Reve this movie is based on. Gerard Reve is also the fictional name of the main character (a tormented writer, played by Jeroen Krabbé, balancing on the dangerous line of a severe psychosis). Now, has anybody stopped and thought about the fact that the word "rêve" is French for "dream"? And the film does feature a lot of dream-like/nightmarish sequences, often to that extend that you don't always know for sure if Gerard is awake or dreaming himself. Could this be coincidence...? Maybe it's just me, but I don't think so. Renée Soutendijk is pretty amazing as the leading lady (in a rather demanding role). She sometimes seems to be guilty of over-acting (in a subtle way). But that aspect was clearly intentional to portray the character she plays, since as this movie progresses, you become unsure about what to actually think of this lady and her intentions. Proves again what an excellent actress she is. I might add that the movie contains also several scenes portraying full frontal male & female nudity, as well as some rather explicit sex-scenes (and you will even notice that some scenes and aspects clearly were the blueprints of scenes later to be shot for Verhoeven's BASIC INSTINCT).<br /><br />Another aspect this movie has is a lot of symbolism and biblical references/images, which supposedly made the film thoroughly hated by some conservative/catholic movements at the time of its European release. Either way, it makes the movie worthy of a second viewing. Now, someone recently told me he had grave misgivings about DE VIERDE MAN. One of them being that the film supposedly manoeuvers itself into a position where it needs the divine intervention of the Virgin Mary to resolve itself. I myself have big issues with the way Catholicism has been, and still is sometimes, portrayed in many movies in any genre (so not only when it comes to religiously themed horror movies). But surprisingly, I had no misgivings whatsoever when it comes to THE FOURTH MAN. Although the Virgin Mary-aspect in the plot did make me scratch my head at one point, I also had fun with it, in a way. I think the keyword as to why it didn't bother me at all is 'duality'. Because, this movie works on two levels. Although 'divine intervention' might have resolved the plot-line from the protagonist's point of view... on the other hand: the movie implies that all this might have been the delirious ramblings of a raving madman. And that's the fun part: You never know for sure. And then there's the question: Could it be that Gerard Reve was somehow receiving distorted visions of things to come... like receiving omens? At one point in the movie, Gerard even tries to fool Christine into believing he is clairvoyant. The way he is playing Christine in that particular scene is exquisite to behold.<br /><br />So with its compelling story, convincing acting performances and adequate direction, DE VIERDE MAN is a very much recommended viewing indeed (especially if you enjoy a solid European psychological horror film). But make sure you see the original Dutch version (not the dubbed one).

Integrated ferroelectric plasmonic modulators featuring large bandwidths,
broad optical operation range, resilience to high temperature and ultracompact
footprint are introduced. Measurements show a modulation bandwidth of 70 GHz
and a temperature stability up to 250{\deg}C. Mach-Zehnder interferometer
modulators with 10-$\mu$m-long phase shifters were operated at 116 Gbit/s PAM-4
and 72 Gbit/s NRZ. Wide and open eye diagrams with extinction ratios beyond 15
dB were found. The fast and robust devices are apt to an employment in
industrial environments.

Good Bedroom charger
Bought one for my roommate to use since he has so many devices. Works well and it’s nice to have one home for everything. Even if you don’t have the watch, it looks good for just the phone and headphones. Looks nice on the shelf since there’s no clutter.

In this paper we construct a family of steady symmetric vortex patches for
the incompressible Euler equations in an open disk. The result is obtained by
studying a variational problem in which the kinetic energy of the fluid is
maximized subject to some appropriate constraints for the vorticity. Moreover,
we show that these vortex patches shrink to a given minimum point of the
corresponding Kirchhoff-Routh function as the vorticity strength parameter goes
to infinity.

These tips were perfectly fine at first, and look very nice on the Apple Pencil, but wore out very quickly. I would honestly just recommend buying the apple specific tips because they last much longer than these ones. In 3 weeks I have gone through both tips, just with normal usage of the pencil.

Information theory has been very successful in obtaining performance limits
for various problems such as communication, compression and hypothesis testing.
Likewise, stochastic control theory provides a characterization of optimal
policies for Partially Observable Markov Decision Processes (POMDPs) using
dynamic programming. However, finding optimal policies for these problems is
computationally hard in general and thus, heuristic solutions are employed in
practice. Deep learning can be used as a tool for designing better heuristics
in such problems. In this paper, the problem of active sequential hypothesis
testing is considered. The goal is to design a policy that can reliably infer
the true hypothesis using as few samples as possible by adaptively selecting
appropriate queries. This problem can be modeled as a POMDP and bounds on its
value function exist in literature. However, optimal policies have not been
identified and various heuristics are used. In this paper, two new heuristics
are proposed: one based on deep reinforcement learning and another based on a
KL-divergence zero-sum game. These heuristics are compared with
state-of-the-art solutions and it is demonstrated using numerical experiments
that the proposed heuristics can achieve significantly better performance than
existing methods in some scenarios.

Before 2004, nearly all GRB afterglow data could be understood in the context
of the external shocks model. This situation has changed in the past two years,
when it became clear that some afterglow components should be attributed to the
activity of the central engine; i.e., the {\it central engine afterglow}. We
review here the afterglow emission that is directly related to the GRB central
engine. Such an interpretation proposed by Katz, Piran & Sari, peculiar in
pre-{\it Swift} era, has become generally accepted now.

We discuss possible signatures of the tree level FCNC, which results from the
non-unitarity of CKM matrix. We first define the unitaity step-by-step, and
possible test of the non-unitaity through the 4-value-KM parametrization. We,
then, show how the phase angle of the unitary triangle would change in case of
the vector-like down quark model. As another example of tree FCNC, we
investigate the leptophobic $Z'$ model and its application to the recent $B_s$
mixing measurements.

The first simultaneous operation of the AURIGA detector and the LIGO
observatory was an opportunity to explore real data, joint analysis methods
between two very different types of gravitational wave detectors: resonant bars
and interferometers. This paper describes a coincident gravitational wave burst
search, where data from the LIGO interferometers are cross-correlated at the
time of AURIGA candidate events to identify coherent transients. The analysis
pipeline is tuned with two thresholds, on the signal-to-noise ratio of AURIGA
candidate events and on the significance of the cross-correlation test in LIGO.
The false alarm rate is estimated by introducing time shifts between data sets
and the network detection efficiency is measured with simulated signals with
power in the narrower AURIGA band. In the absence of a detection, we discuss
how to set an upper limit on the rate of gravitational waves and to interpret
it according to different source models. Due to the short amount of analyzed
data and to the high rate of non-Gaussian transients in the detectors noise at
the time, the relevance of this study is methodological: this was the first
joint search for gravitational wave bursts among detectors with such different
spectral sensitivity and the first opportunity for the resonant and
interferometric communities to unify languages and techniques in the pursuit of
their common goal.

A Brody curve, a.k.a. normal curve, is a holomorphic map from the complex
line to the complex projective space of dimension n, such that the family of
its translations is normal. We prove that Brody curves omitting n hyperplanes
in general position have growth order at most one, normal type. This
generalizes a result of Clunie and Hayman who proved it for n=1.

Given an ideal $I$ and a polynomial $f$ the Ideal Membership Problem is to
test if $f\in I$. This problem is a fundamental algorithmic problem with
important applications and notoriously intractable. We study the complexity of
the Ideal Membership Problem for combinatorial ideals that arise from
constrained problems over the Boolean domain. As our main result, we identify
the borderline of tractability. By using Gr\"{o}bner bases techniques, we
extend Schaefer's dichotomy theorem [STOC, 1978] which classifies all
Constraint Satisfaction Problems over the Boolean domain to be either in P or
NP-hard. Moreover, our result implies necessary and sufficient conditions for
the efficient computation of Theta Body SDP relaxations, identifying therefore
the borderline of tractability for constraint language problems. This paper is
motivated by the pursuit of understanding the recently raised issue of bit
complexity of Sum-of-Squares proofs [O'Donnell, ITCS, 2017]. Raghavendra and
Weitz [ICALP, 2017] show how the Ideal Membership Problem tractability for
combinatorial ideals implies bounded coefficients in Sum-of-Squares proofs.

This film, which is based on a true story, comes from first time director and long time actor, Denzel Washington. Denzel Washington has given us some of the best performances of the last decade, as a black soldier in the Civil War in Glory, and a lawyer in the acclaimed Philadelphia. And of course, he made special notoriety last year when he won the Academy Award for Best Actor in Training Day, in which Denzel Washington became the first African American to receive the award for Best Actor. I guess Denzel wanted a change of pace, so he chose to direct Antwone Fisher, in which he also stars. Fisher is played by Derek Luke, who is new to the silver screen, but has made some guest appearances on such television shows as King of Queens, and he will be appearing in the upcoming film release of Biker Boyz.<br /><br /> This is a truly well done film from Denzel Washington, considering it was his first time directing. Undoubtedly, Denzel felt some kind of commitment and believed in the real life story of Antwone Fisher. Antwone Fisher is about a young African American man in the Navy who constantly gets into fights, and after one particular brawl he is sent to see a Navy psychiatrist named Jerome Davenport, played by Denzel Washington. Davenport helps Antwone to deal with his troubled past and learn to move on with his life, by finding his birth mother who had to give him up at birth because she was in prison. What makes this film good is the fact that it's not overly melodramatic. I was expecting something a little more like Good Will Hunting, with a lot of swearing, fighting and vulgarity. Not that I didn't like Good Will Hunting, or the swearing, fighting and vulgarity of the film were out of place. Quite the contrary! However, Antwone Fisher is a true story, and I don't think that Washington wanted to sensationalize the story for dramatic affect in the film. Don't get me wrong, there are moments when we see Antwone fighting, carrying on and having moments when it seems like the world is closing in on him. After all, in his first session with his psychiatrist, the character played by Washington, Devenport asks Fisher where he was born, and Fisher's response is, `from under a rock,' an obvious jab at the pressures waning on Antwone Fisher's soul. But I had to appreciate the fact that this film wasn't sensationalized for dramatic affect. I think it shows real character on the part of Denzel Washington to deliver a more realistic story and to avoid the typical clichés that are common in Hollywood films, even those based on true stories. One other point that I would like to bring up about Antwone Fisher is the acting. Over all, performances were good in the film, but not great. At times, I think it was a bit obvious that the main characters were actors, but overall, to complain about performances in this film would be ludicrous. One actress that I would like to point out in this film is Viola Davis. She plays Antwone's mother, but she says barely two sentences in the movie at all, but not so much because she appears at the end of the film, but more because she in shock that her long lost son, Antwone has found her. What I would like to point out about her as an actress in the lack of use of her. She in basically a character actress, and I haven't seen her play any really elaborate roles. She made appearances in Traffic, Out Of Sight, Kate & Leopold, and two recent films: Far From Heaven and Solaris. In Steven Soderberg's remake of Solaris, she played a scientist on a doomed space craft orbiting a planet. In that film, she is confronted by George Clooney's character and she drawn to tears by what Clooney tells her in a particular scene. When I first saw Solaris, I remember seeing her tear up in the scene and thinking, wow, this woman can act. It was as if you could feel the character's grief. In that brief shot of her face, she gave so much expression and I honestly felt very sorry for her character's sadness and trouble in the film. I think she has definite potential as an actress and should be used more often perhaps in leading roles, rather than just as a character driven actress. Nonetheless, Antwone Fisher is a very good movie. Denzel Washington, as always, pulls off a great performance and he gives us a great directorial debut. Also, Derek Luke is a very talented actor. I think that Antwone Fisher will bring his immense critical fame for his portrayal of the troubled man, but I think that his public popularity will increase with the release of Biker Boyz, which also stars Lawrence Fishburn. Antwone Fisher is based on the book `Finding Fish: A Memoir,' by Antwone Quenton Fisher. ***

Steady-state access to intraband transitions in colloidal quantum dots
(CQDs), via heavy doping, allows exploiting the electromagnetic spectrum at
energies below the band gap. CQD intraband optoelectronics opens up a new path
to cheap mid- and long-wavelength infrared photodetectors and light-emitting
devices, which today employ mostly epitaxial materials. As a recent field of
experimental research, thorough studies of the basic properties of intraband
transitions in CQDs are still lacking. In this work, we investigate the size
and temperature dependence of the intraband transition in heavily n-doped PbS
quantum dot (QD) films. We measure the absorption coefficient of the intraband
transition to be in the order of $10^4$ cm$^{-1}$, which is comparable to the
value of the interband absorption coefficient. Additionally, we determine the
size-dependence of the oscillator strength of the intraband transition. We
demonstrate a negative dependence of the intraband energy with temperature, in
contrast to the positive dependence of the interband transition.

The singular value and spectral distribution of Toeplitz matrix sequences
with Lebesgue integrable generating functions is well studied. Early results
were provided in the classical Szeg{\H{o}} theorem and the Avram-Parter
theorem, in which the singular value symbol coincides with the generating
function. More general versions of the theorem were later proved by Zamarashkin
and Tyrtyshnikov, and Tilli. Considering (real) nonsymmetric Toeplitz matrix
sequences, we first symmetrize them via a simple permutation matrix and then we
show that the singular value and spectral distribution of the symmetrized
matrix sequence can be obtained analytically, by using the notion of
approximating class of sequences. In particular, under the assumption that the
symbol is sparsely vanishing, we show that roughly half of the eigenvalues of
the symmetrized Toeplitz matrix (i.e. a Hankel matrix) are negative/positive
for sufficiently large dimension, i.e. the matrix sequence is symmetric
(asymptotically) indefinite.

A motion planning algorithm computes the motion of a robot by computing a
path through its configuration space. To improve the runtime of motion planning
algorithms, we propose to nest robots in each other, creating a nested
quotient-space decomposition of the configuration space. Based on this
decomposition we define a new roadmap-based motion planning algorithm called
the Quotient-space roadMap Planner (QMP). The algorithm starts growing a graph
on the lowest dimensional quotient space, switches to the next quotient space
once a valid path has been found, and keeps updating the graphs on each
quotient space simultaneously until a valid path in the configuration space has
been found. We show that this algorithm is probabilistically complete and
outperforms a set of state-of-the-art algorithms implemented in the open motion
planning library (OMPL).

One of the key questions in understanding the formation and evolution of
galaxies is how starbursts affect the assembly of stellar populations in
galaxies over time. We define a burst indicator ($\eta$), which compares a
galaxy's star formation rates on short ($\sim10$ Myr) and long ($\sim100$ Myr)
timescales. To estimate $\eta$, we apply the detailed time-luminosity
relationship for H$\alpha$ and near-ultraviolet emission to simulated star
formation histories (SFHs) from semi-analytic models and the Mufasa
hydrodynamical cosmological simulations. The average of $\eta$ is not a good
indicator of star formation stochasticity (burstiness); indeed, we show that
this average should be close to zero unless the population has an average SFH
which is rising or falling rapidly. Instead, the width of the $\eta$
distribution characterizes the burstiness of a galaxy population's recent star
formation. We find this width to be robust to variations in stellar initial
mass function and metallicity. We apply realistic noise and selection effects
to the models to generate mock HST and JWST galaxy catalogs and compare these
catalogs with 3D-HST observations of 956 galaxies at $0.65<z<1.5$ detected in
H$\alpha$. Measurements of $\eta$ are unaffected by dust measurement errors
under the assumption that $E(B-V)_\mathrm{stars}=0.44\,E(B-V)_\mathrm{gas}$
(i.e., $Q_\mathrm{sg}=0.44$). However, setting
$Q_\mathrm{sg}=0.8^{+0.1}_{-0.2}$ removes an unexpected dependence of the
average value of $\eta$ upon dust attenuation and stellar mass in the 3D-HST
sample while also resolving disagreements in the distribution of star formation
rates. However, even varying the dust law cannot resolve all discrepancies
between the simulated and the observed galaxies.

In this thesis the data analysis designed by author for the "Pi of the Sky"
experiment is presented. The data analysis consists of data reduction and
specific algorithms for identification of short time scale astrophysical
processes. The algorithms have been tested and their efficiency has been
determined and described. The "Pi of the Sky" prototype is collecting data
since June 2004 and algorithms could be intensively studied and improved during
over 700 nights. A few events of confirmed astrophysical origin and above 100
events in 10s time scale of unknown nature have been discovered. During the
data collection period 3 Gamma Ray Bursts (out of 231) occurred in the field of
view of the telescope, but no optical counterpart has been found. The upper
limits for brightness of the optical counterpart have been determined. The
continuous monitoring of the sky and own trigger for optical flashes allowed to
determine limits on the number of GRBs without corresponding gamma-ray
detection. This allowed determining limits on the ratio of emission collimation
in optical and gamma bands, which is R >= 4.4. The perspectives of the full "Pi
of the Sky" system has been studied and number of positive detections has been
estimated on the level of ~ 2.5 events per year.

Starfucker (which reads Starstruck on my box) was the most amazing movie I have ever seen. I thought that it was one of the best movies I have ever seen. So why not a 10? Nothing is perfect. Jamie Kennedy proves why he is one of my favorite actors in this very interesting look at a darker side of Hollywood. I have forced a few others to watch the movie and they all agreed that it was an outstanding flick.

We develop methods for resummation of instanton lattice series. Using these
tools, we investigate the consequences of the Weak Gravity Conjecture for
large-field axion inflation. We find that the Sublattice Weak Gravity
Conjecture implies a constraint on the volume of the axion fundamental domain.
However, we also identify conditions under which alignment and clockwork
constructions, and a new variant of N-flation that we devise, can evade this
constraint. We conclude that some classes of low-energy effective theories of
large-field axion inflation are consistent with the strongest proposed form of
the Weak Gravity Conjecture, while others are not.

We provide a procedure for resolving, in characteristic 0, singularities of a
variety $X$ embedded in a smooth variety $Y$ by repeatedly blowing up the worst
singularities, in the sense of stack-theoretic weighted blowings up. No
history, no exceptional divisors, and no logarithmic structures are necessary
to carry this out; the steps are explicit geometric operations requiring no
choices; and the resulting algorithm is efficient. A similar result was
discovered independently by McQuillan in a manuscript posted on this archive
simultaneously.

The relationship between Jordan and Lie coalgebras is established. We prove
that from any Jordan coalgebra $\langle A, \Delta\rangle$, it is possible to
construct a Lie coalgebra $\langle L(A), \Delta_{L}\rangle$. Moreover, any dual
algebra of the coalgebra $\langle L(A), \Delta_{L}\rangle$ corresponds to a Lie
algebra that can be determined from the dual algebra for $\langle
A,\Delta\rangle$, following the Kantor--Koecher--Tits process. The structure of
subcoalgebras and coideals of the coalgebra $\langle L(A), \Delta_{L}\rangle$
is characterized.

This paper was motivated by the problem of how to make robots fuse and
transfer their experience so that they can effectively use prior knowledge and
quickly adapt to new environments. To address the problem, we present a
learning architecture for navigation in cloud robotic systems: Lifelong
Federated Reinforcement Learning (LFRL). In the work, We propose a knowledge
fusion algorithm for upgrading a shared model deployed on the cloud. Then,
effective transfer learning methods in LFRL are introduced. LFRL is consistent
with human cognitive science and fits well in cloud robotic systems.
Experiments show that LFRL greatly improves the efficiency of reinforcement
learning for robot navigation. The cloud robotic system deployment also shows
that LFRL is capable of fusing prior knowledge. In addition, we release a cloud
robotic navigation-learning website based on LFRL.

In this article, we calculate the branching ratios of $B \to K_0^*(1430) K$
decays by employing the perturbative QCD (pQCD) approach at leading order. We
perform the evaluations in the two scenarios for the scalar meson spectrum. We
find that (a) the leading order pQCD predictions for the branching ratio
$Br(B^+ \to K^+ \bar{K_0^*}(1430)^0)$ which is in good agreement with the
experimental upper limit in both scenarios, while the pQCD predictions for
other considered $B \to K_0^*(1430) K$ decay modes are also presented and will
be tested by the LHC experiments; (b) the annihilation contributions play an
important role in these considered decays, for $B^0 \to {K_0^*}(1430)^\pm
{K}^\mp$ decays, for example, which are found to be $(1-4) \times 10^{-6}$.

We construct embedded ancient solutions to mean curvature flow related to
certain classes of unstable minimal hypersurfaces in $\mathbb{R}^{n+1}$ for $n
\geq 2$. These provide examples of mean convex yet nonconvex ancient solutions
that are not solitons, meaning that they do not evolve by rigid motions or
homotheties. Moreover, we construct embedded eternal solutions to mean
curvature flow in $\mathbb{R}^{n+1}$ for $n \geq 2$. These eternal solutions
are not solitons, are $O(n)\times O(1)$-invariant, and are mean convex yet
nonconvex. They flow out of the catenoid and are the rotation of a profile
curve which becomes infinitely far from the axis of rotation. As $t \to
\infty$, the profile curves converge to a grim reaper for $n \geq 3$ and become
flat for $n=2$. Concerning these eternal solutions, we also show they are
asymptotically unique up to scale among the embedded $O(n)\times
O(1)$-invariant, eternal solutions with uniformly bounded curvature and a sign
on mean curvature.

Pretty good tape
I knocked this tape down 2 stars because it doesn't stick to my skin very well. I have to wrap my thumbs a few times to get it to stick and then during my workout it rolls over itself or loosens more. I really like how flexible the tape is but wish it would stick better.

Size is perfect for me.
I bought this to replace a different RFID wallet I had that was smaller and busting at the seams because of how much I had crammed into it. I really like the size of this and how many card slots there are and the two zippered pockets. The double snap closures are awesome too. The only thing I don’t care for is when you open it, all of your cards are visible as you take one out and you must hold it vertical versus horizontal. Other than that, it’s a great value and looks amazing.

I love Sabrina! Its one of my fave shows!! My favourite episodes are; the one where she turns Libby into a geek, the first episode, the true love episode and most of the rest from the first series. I do think the college episodes were not as good as the high school ones but they were better than the last series which was awful. Valerie was a good character as she was more rounded than Jenny, but Jenny was in some brilliant episodes. Hilda and Zelda were amazing, and there seemed to be no explanation for where they went! Libby was a good character too. I never liked Morgan or Roxy, they just weren't as good as her other friends.

Peels off easily without taking part of the cake with it.
I didn't know parchment liners were available until I read it on a baking website. Since I use parchment in all my baking I was glad to find these. They are a good basic liner and I will be reordering as needed.

RF-induced micromotion in trapped ion systems is typically minimised or
circumvented to avoid off-resonant couplings for adiabatic processes such as
multi-ion gate operations. Non-adiabatic entangling gates (so-called `fast
gates') do not require resolution of specific motional sidebands, and are
therefore not limited to timescales longer than the trapping period. We find
that fast gates designed for micromotion-free environments have significantly
reduced fidelity in the presence of micromotion. We show that when fast gates
are designed to account for the RF-induced micromotion, they can, in fact,
out-perform fast gates in the absence of micromotion. The state-dependent force
due to the laser induces energy shifts that are amplified by the
state-independent forces producing the micromotion. This enhancement is present
for all trapping parameters and is robust to realistic sources of experimental
error. This result paves the way for fast two-qubit entangling gates on
scalable 2D architectures, where micromotion is necessarily present on at least
one inter-ion axis.

We present an analysis of the X-ray data of a magnetic cataclysmic variable,
BG CMi, obtained with ROSAT in March 1992 and with ASCA in April 1996. We show
that four peaks clearly exist in the X-ray pulse profile, unlike a single peak
found in the optical profile. The fluxes of two major pulses are $\sim 2 - 5$
times larger than those of two minor pulses. The fraction of the total pulsed
flux increases from 51% to 85% with increasing energy in 0.1 $-$ 2.0 keV,
whereas it decreases from 96% to 22% in 0.8 $-$ 10 keV. We discuss the
implications of our findings for the origin of the pulse profile and its energy
dependence.

Love this game, but do we really need to play it again?
Other than improved frame rate and resolution, this is the same game you played back in 2011. While the frame rate is almost enough to warrant the upgrade, there are some details that could've been ironed out (like the paper trees near the Undead Parish) to make this a complete remaster. In short, new comers welcome and good luck there's a lot to love here. For the veterans, however, just realize you're paying for a slightly glossier 'Souls 1.

The general linear model (GLM) is a well established tool for analyzing
functional magnetic resonance imaging (fMRI) data. Most fMRI analyses via GLM
proceed in a massively univariate fashion where the same design matrix is used
for analyzing data from each voxel. A major limitation of this approach is the
locally varying nature of signals of interest as well as associated confounds.
This local variability results in a potentially large bias and uncontrolled
increase in variance for the contrast of interest. The main contributions of
this paper are two fold (1) We develop a statistical framework called SMART
that enables estimation of an optimal design matrix while explicitly
controlling the bias variance decomposition over a set of potential design
matrices and (2) We develop and validate a numerical algorithm for computing
optimal design matrices for general fMRI data sets. The implications of this
framework include the ability to match optimally the magnitude of underlying
signals to their true magnitudes while also matching the "null" signals to zero
size thereby optimizing both the sensitivity and specificity of signal
detection. By enabling the capture of multiple profiles of interest using a
single contrast (as opposed to an F-test) in a way that optimizes for both bias
and variance enables the passing of first level parameter estimates and their
variances to the higher level for group analysis which is not possible using
F-tests. We demonstrate the application of this approach to in vivo
pharmacological fMRI data capturing the acute response to a drug infusion, to
task-evoked, block design fMRI and to the estimation of a haemodynamic response
function (HRF) response in event-related fMRI. Our framework is quite general
and has potentially wide applicability to a variety of disciplines.

This paper describes a new but state-of-the-art approach to provide
authenticity in mqtt sessions using the means of zero-knowledge-proofs. This
approach completely voids session hijacking for the mqtt protocol and provides
authenticity without the need for any network-security nor channel-security nor
broker-based predefined ACLs. The presented approach does not require the
broker to keep any secrets for session handling, what so ever. Moreover, it
allows the clientID, which represents the identification for a session, to be
publicly known. The presented approach allows completely anonymous but
authentic sessions, hence the broker does not need any a priori knowledge of
the client-party. As it is especially targeted for applications within the
world of IoT, the presented approach is tuned to require only the minimum in
extra power in terms of energy and space. The approach does not introduce any
new concept, but simply fusions a state-of-the-art cryptographic zero knowledge
proof of identity with the existing MQTT-5 specification. Thus no protocol
extension is required in order to provide the targeted security properties. The
described approach is completely agnostic to the application layer at the
client side and is only required during mqtt-session establishment.

Satellite DNA spans megabases of eukaryotic sequence and evolves rapidly. Paradoxically, satellite-rich genomic regions mediate strictly conserved, essential processes like chromosome segregation and nuclear structure. A leading resolution to this paradox posits that satellite DNA and satellite-associated chromosomal proteins coevolve to preserve these essential functions. We experimentally test this model of intra-genomic coevolution by conducting the first evolution-guided manipulation of both chromosomal protein and DNA satellite. The 359bp satellite spans an 11Mb array in D. melanogaster that is absent from its sister species, D. simulans. This species-specific DNA satellite colocalizes with the adaptively evolving, ovary-enriched protein, Maternal Haploid (MH)-the Drosophila homolog of Spartan. To determine if MH and 359 coevolve, we swapped the D. simulans version of MH ("MH[sim]") into D. melanogaster. MH[sim] triggers ovarian cell death, reduced ovary size, and loss of mature eggs. Surprisingly, the D. melanogaster mh null mutant has no such ovary phenotypes, suggesting that MH[sim] is toxic in a D. melanogaster background. Using both cell biology and genetics, we discovered that MH[sim] poisons oogenesis through a DNA damage pathway. Remarkably, deleting the D. melanogaster-specific 359 satellite array completely restores mh[sim] germline genome integrity and fertility, consistent with a history of coevolution between these two fast-evolving loci. Germline genome integrity and fertility are also restored by overexpressing Topoisomerase II (Top2), suggesting that MH[sim] interferes with Top2-mediated processing of 359. The observed 359-MH[sim] cross-species incompatibility supports a model under which ostensibly inert repetitive DNA and essential chromosomal proteins must coevolve to preserve germline genome integrity.

Use with caution. Inconsistent stream.
This product is alright. For the size, it's ideal for one person. I bought it to get myself to drink more water and shoot for about 1.5-2 refills of these per day. Something about the taste of the water is a little off. I'm not sure why as I have been drinking water from a PUR pitcher in the past and through my Hydroflask. Whenever I drink through that, water usually tastes amazing. With this pitcher it's just ehh. On top of that, the stream of this pitcher is unpredictable!! A lot of people mentioned that it was slow, but for me it'll go from a small stream to freaking Niagara Falls. Sadly I didn't know this, and upon pouring water into my bottle right next to my Dell Inspiron, the water suddenly gushed out all over my table and keyboard. Several keys ended up shorting out and I had to buy another laptop, so that was pretty scarring. I guess it's my fault for doing it next to my technology, but I don't get what is up with that damn stream.... This usually happens when it's nearly full or almost empty. Be careful with this thing. I'd return it but threw out the packaging. Hopefully you'll have a better experience.

Although teenage boys remain the most avid video game players in the U.S., they're being joined at the console by another group — their grandparents.
More than 10 million Americans age 50 and older became active video gamers over the past three years, according to an AARP survey. In 2016, there were 40 million senior gamers, a number that's mushroomed to about 51 million in 2019, the survey found.
To be sure, people in their mid-30s still make up a majority of the gaming industry's customers, but the rise in gray-haired gamers has big implications for how companies like Electronic Arts and Nintendo market and create new products, industry observers say.
The rise in older gamers is fueled in part by people who use gaming to spend quality time with grandchildren, but many are also drawn to video games for enjoyment and intellectual challenge.
"It's stress release, connecting socially and staying mentally sharp," said Alison Bryant, AARP's senior vice president of research. "This is wonderfully bite-sized bits of entertainment for them."
The nostalgia effect
The AARP survey, which draws from more than 3,700 online responses, found that women accounted for the largest increase in older gamers in recent years.
Take Pennsylvania resident Barbara Evans, 79, who loves playing Nintendo Wii bowling with three of her friends in her retirement community in Jenkintown. Evans and friends gather twice a week and bowl three digital rounds, a year-long tradition that "has become a very social thing," she said.
"It's a lot of fun when there's other people coming and going and they'll stop and watch and they'll cheer on this one or that one," Evans said.
Evans once bowled a 268 on the game, a score that has become "my claim to fame here."
The game helps Evans think back to her days as a single 20-something working as a nurse. She would finish an eight-hour shift then leave at 11 p.m. to bowl in a competitive league. When Evans got married, she and her husband bowled in a league for several years. She has played Wii bowling for the past seven years.
Forza Horizon 4, a car racing game on Xbox, is the game of choice for Kansas City resident Michelle Kelley. The retired clinical psychologist plays for about two hours daily.
"It's got cars that I currently own and cars that I owned as a teen," Kelley, 73, said, mentioning the 1997 BMW E36 he likes to use in the game. "The one in the game is a coupe and mine is a convertible, so I can drive my own car in the game."
Finding community
Video games that offer a sense of online community and interaction are popular with older gamers because of the isolation many seniors feel, said Greg Portell, head of global consumer industries and retail price at consulting firm AT Kearney.
The AARP data further shows that golden-year gamers are a growing consumer base and "a sizable market that deserves development attention," he added. "All the indicators show it'll be financially lucrative to do that."
Americans over 50 spent $3.5 billion on video games and accessories between in first half of the year, up sharply from $523 million during the same period in 2016, according to AARP. They spent an average of $70 when purchasing video games.
About 164 million people — a figure that includes seniors— played video games in 2018, which helped the industry grab a record $43.4 billion in sales.
Portell expects major video game developers to target seniors over the next decade. For instance, savvy companies could integrate voice controls and sensors, enabling older people to continue playing even if they're not as nimble as they once were.
"And the more they can build trust into the product, the better," he said. "Financial security and safety – really creating something where the [senior gaming] community can let their guard down without having to worry about being scammed."
Bryant agrees that older gamers represent a growth market for gaming companies. "One of the reasons we put out this study is to remind the gaming industry that 'Hey, these are the people who are playing your games'," she said.

After extensive quasi-static shearing, dense dry granular flows attain a
steady-state condition of porosity and deviatoric stress, even as particles are
continually rearranged. The paper considers two-dimensional flow and derives
the probability distributions of two topological measures of particle
arrangement---coordination number and void valence---that maximize topological
entropy. By only considering topological dispersion, the method closely
predicts the distribution of void valences, as measured in discrete element
(DEM) simulations. Distributions of coordination number are also derived by
considering packings that are geometrically and kinetically consistent with the
particle sizes and friction coefficient. A cross-entropy principle results in a
distribution of coordination numbers that closely fits DEM simulations.

Horrible customer service
One of 3 batteries came broken. The company wants us to mail it back that in it's broken condition. Guess what, FedEx or UPS won't ship a broken battery as it's forbidden cargo. This company tanks high on the worst customer service. Stear clear of first web sales. You've been warned.

Proving super-polynomial size lower bounds for syntactic multilinear
Algebraic Branching Programs(smABPs) computing an explicit polynomial is a
challenging problem in Algebraic Complexity Theory. The order in which
variables in $\{x_1,\ldots,x_n\}$ appear along source to sink paths in any
smABP can be viewed as a permutation in $S_n$. In this article, we consider the
following special classes of smABPs where the order of occurrence of variables
along a source to sink path is restricted:
Strict circular-interval ABPs: For every subprogram the index set of
variables occurring in it is contained in some circular interval of
$\{1,\ldots,n\}$.
L-ordered ABPs: There is a set of L permutations of variables such that every
source to sink path in the ABP reads variables in one of the L orders.
We prove exponential lower bound for the size of a strict circular-interval
ABP computing an explicit n-variate multilinear polynomial in VP. For the same
polynomial, we show that any sum of L-ordered ABPs of small size will require
exponential ($2^{n^{\Omega(1)}}$) many summands, when $L \leq
2^{n^{1/2-\epsilon}}, \epsilon>0$. At the heart of above lower bound arguments
is a new decomposition theorem for smABPs: We show that any polynomial
computable by an smABP of size S can be written as a sum of O(S) many
multilinear polynomials where each summand is a product of two polynomials in
at most 2n/3 variables computable by smABPs. As a corollary, we obtain a low
bottom fan-in version of the depth reduction by Tavenas [MFCS 2013] in the case
of smABPs. In particular, we show that a polynomial having size S smABPs can be
expressed as a sum of products of multilinear polynomials on $O(\sqrt{n})$
variables, where the total number of summands is bounded by $2^{O(\sqrt{n}\log
n \log S)}$. Additionally, we show that L-ordered ABPs can be transformed into
L-pass smABPs with a polynomial blowup in size.

Large scale cloud networks consist of distributed networking and computing
elements that process critical information and thus security is a key
requirement for any environment. Unfortunately, assessing the security state of
such networks is a challenging task and the tools used in the past by security
experts such as packet filtering, firewall, Intrusion Detection Systems (IDS)
etc., provide a reactive security mechanism. In this paper, we introduce a
Moving Target Defense (MTD) based proactive security framework for monitoring
attacks which lets us identify and reason about multi-stage attacks that target
software vulnerabilities present in a cloud network. We formulate the
multi-stage attack scenario as a two-player zero-sum Markov Game (between the
attacker and the network administrator) on attack graphs. The rewards and
transition probabilities are obtained by leveraging the expert knowledge
present in the Common Vulnerability Scoring System (CVSS). Our framework
identifies an attacker's optimal policy and places countermeasures to ensure
that this attack policy is always detected, thus forcing the attacker to use a
sub-optimal policy with higher cost.

In a universe with a cosmological constant, the large-scale gravitational
potential varies in time and this is, in principle, observable. Using an N-body
simulation of a $\Lambda$CDM universe, we show that linear theory is not
sufficiently accurate to predict the power spectrum of the time derivative,
$\dot{\Phi}$, needed to compute the imprint of large-scale structure on the
cosmic microwave background (CMB). The linear part of the $\dot{\Phi}$ power
spectrum (the integrated Sachs-Wolfe effect or ISW) drops quickly as the
relative importance of $\Omega_{\Lambda}$ diminishes at high redshift, while
the non-linear part (the Rees-Sciama effect or RS) evolves more slowly with
redshift. Therefore, the deviation of the total power spectrum from linear
theory occurs at larger scales at higher redshifts. The deviation occurs at
$k\sim 0.1 $ $h$ Mpc$^{-1}$ at $z=0$. The cross-correlation power spectrum of
the density $\delta$ with $\dot{\Phi}$ behaves differently to the power
spectrum of $\dot{\Phi}$. Firstly, the deviation from linear theory occurs at
smaller scales ($k\sim 1 $ $h$ Mpc$^{-1}$ at $z=0$). Secondly, the correlation
becomes negative when the non-linear effect dominates. For the
cross-correlation power spectrum of galaxy samples with the CMB, the non-linear
effect becomes significant at $l\sim 500$ and rapidly makes the cross power
spectrum negative. For high redshift samples, the cross-correlation is expected
to be suppressed by $5-10%$ on arcminute scales. The RS effect makes a
negligible contribution to the large-scale ISW cross-correlation measurement.
However, on arc-minute scales it will contaminate the expected
cross-correlation signal induced by the Sunyaev-Zel'dovich effect.

Decent for the price, but doesn't provide blackout privacy
Just received today. For the price, it's a decent screen protector, but d not rely on it too heavily to provide the privacy it advertises. The side view of the screen is dimmed rather than black. I have seen people's phone's where it looks like the screen is black even with me standing right next to them. I might ask which privacy screen protector they are using because I know this one isn't it. Might return and use the money towards a better quality screen protector.

Syntactic theory has traditionally adopted a constructivist approach, in
which a set of atomic elements are manipulated by combinatory operations to
yield derived, complex elements. Syntactic structure is thus seen as the result
or discrete recursive combinatorics over lexical items which get assembled into
phrases, which are themselves combined to form sentences. This view is common
to European and American structuralism (e.g., Benveniste, 1971; Hockett, 1958)
and different incarnations of generative grammar, transformational and
non-transformational (Chomsky, 1956, 1995; and Kaplan & Bresnan, 1982; Gazdar,
1982). Since at least Uriagereka (2002), there has been some attention paid to
the fact that syntactic operations must apply somewhere, particularly when
copying and movement operations are considered. Contemporary syntactic theory
has thus somewhat acknowledged the importance of formalizing aspects of the
spaces in which elements are manipulated, but it is still a vastly
underexplored area. In this paper we explore the consequences of
conceptualizing syntax as a set of topological operations applying over spaces
rather than over discrete elements. We argue that there are empirical
advantages in such a view for the treatment of long-distance dependencies and
cross-derivational dependencies: constraints on possible configurations emerge
from the dynamics of the system.

The individualization-refinement paradigm for computing a canonical labeling
and the automorphism group of a graph is investigated. A new algorithmic design
aimed at reducing the size of the associated search space is introduced, and a
new tool, named "Traces", is presented, together with experimental results and
comparisons with existing software, such as McKay's "nauty". It is shown that
the approach presented here leads to a huge reduction in the search space,
thereby making computation feasible for several classes of graphs which are
hard for all the main canonical labeling tools in the literature.

This paper develops a bias correction scheme for a multivariate
heteroskedastic errors-in-variables model. The applicability of this model is
justified in areas such as astrophysics, epidemiology and analytical chemistry,
where the variables are subject to measurement errors and the variances vary
with the observations. We conduct Monte Carlo simulations to investigate the
performance of the corrected estimators. The numerical results show that the
bias correction scheme yields nearly unbiased estimates. We also give an
application to a real data set.

great product. I use these to secure my expensive ...
great product. I use these to secure my expensive glassware (I'm a collector) to my table top/ display stands in my living room. I have tested this to be true; if you use 4 pieces of Velcro on a 5 lb glass sculpture, with it securely velcroed to my 3' , 3" display stand and you shove the table over the glass sculpture stays in place on the table. however my four foot stand didn't go so hot.... R.I.P.. BUT however there has never been a product like this that came even close to satisfying my strange NEED to secure my glass ware to my table.

A serial killer dies in a snowstorm and gets mutated into Frosty the Snowman's evil twin. Then goes on a killing spree. Interesting plot. Sounds scary. And it is scary. If you're five years old. Otherwise, it's kind of cheesy. I saw it on cable and I'm glad I didn't pay money to see it. It has all the charm and style of a low-budget movie which may become a cult film. I'm sure it has a loyal fan base somewhere. I'm just not in it. Even though I didn't like the movie as a whole, there were some scenes I found amusing. Such as the bathtub scene and the post-explosion scene with the Picasso reference. It was also enjoyable to watch the many ways the heroes try to kill Jack and he just doesn't seem to want to die. In short, "Jack Frost" is a good low-budget B-movie comedy, but a bad low-budget B-movie horror.

An algorithmic method using conservation law multipliers is introduced that
yields necessary and sufficient conditions to find invertible mappings of a
given nonlinear PDE to some linear PDE and to construct such a mapping when it
exists. Previous methods yielded such conditions from admitted point or contact
symmetries of the nonlinear PDE. Through examples, these two linearization
approaches are contrasted.

As access to banking services through digital channels continues to grow, so does the need to protect consumers against the prevalence of online banking fraud.
Due to the prevalence of banking scams, we urge consumers to be more vigilant and familiarise themselves with the different types of online banking fraud.
The following are the latest online banking scams consumers should be wary of:
Flight purchase debit scams
You will receive an SMS informing you of a flight purchase debited to your account.
Fraudsters will ask you to select a link in the SMS to revise the transaction.
When you select the link, you will be redirected to a fake bank website.
You are then redirected to an ‘Update and Confirm Details’ screen requesting more information to be verified.
The fraudsters will now be in a position to access your banking profile.
Social media scams
Beware of fraudsters pretending to represent the bank you use on social media channels such as Facebook, Twitter, LinkedIn, WhatsApp or any other social media platform.
The bank will never ask for your credit or cheque card, account number, online banking login details or password or One Time Pin (OTP) on social media platforms.
The official accounts also display a blue tick indicating they are verified.
Change of banking details scam
You will receive an email that allegedly comes from one of your suppliers asking you to update your banking details.
Beware of this, even if it is on the supplier’s letterhead.
Contact your supplier on the number you already have for them and not the one on the fraudulent letter.
Speak to someone you know at the supplier to confirm the change in banking details.
Copy of payment notification scam
You will receive an email requesting you to open a copy of your payment notification.
Fraudsters will prompt you to login via the email attachment.
When you open the attachment in the email, you will be redirected to a fake bank website.
In an attempt to steal your banking details you will be requested to login.
As soon as you enter your login details on the screen, you are redirected to a successfully logged out screen.
The fraudsters will now be in a position to access your banking profile.
419 scams
This is communication by email to a recipient making an offer that would result in a large payoff for the recipient.
The details vary and large amounts of money are usually involved.
The victims’ banking details as well as sums of money are said to be required in advance in order to facilitate the payment of the funds.
Essentially, the promised money transfer never happens and the fraudsters may use the victims’ banking details to withdraw money for themselves.
Phishing
Communication seemingly from the bank or other companies that gets you to disclose personal information such as your ID number, address, account number, username, login details, password and PIN.
This information can also be used to gain unauthorised access to your banking account online.
OTP email fraud
Using various methods of phishing, criminals also try to get access to your email accounts, commonly Gmail, Yahoo, etc.
They produce fake login sites that look like Gmail or Yahoo.
Once they have your email username and password, they have access to your emails (statements, personal communications) and this helps a criminal build a social profile of you.
Criminals can also intercept OTPs that are sent to emails once they have access to your email account.
OTP Sim swap fraud
Once criminals are in possession of your username and password, they can easily access your accounts on online banking.

We introduce and analyse two algorithms for exploration-exploitation in
discrete and continuous Markov Decision Processes (MDPs) based on exploration
bonuses. SCAL$^+$ is a variant of SCAL (Fruit et al., 2018) that performs
efficient exploration-exploitation in any unknown weakly-communicating MDP for
which an upper bound C on the span of the optimal bias function is known. For
an MDP with $S$ states, $A$ actions and $\Gamma \leq S$ possible next states,
we prove that SCAL$^+$ achieves the same theoretical guarantees as SCAL (i.e.,
a high probability regret bound of $\widetilde{O}(C\sqrt{\Gamma SAT})$), with a
much smaller computational complexity. Similarly, C-SCAL$^+$ exploits an
exploration bonus to achieve sublinear regret in any undiscounted MDP with
continuous state space. We show that C-SCAL$^+$ achieves the same regret bound
as UCCRL (Ortner and Ryabko, 2012) while being the first implementable
algorithm with regret guarantees in this setting. While optimistic algorithms
such as UCRL, SCAL or UCCRL maintain a high-confidence set of plausible MDPs
around the true unknown MDP, SCAL$^+$ and C-SCAL$^+$ leverage on an exploration
bonus to directly plan on the empirically estimated MDP, thus being more
computationally efficient.

We construct a non-equilibrium steady state and calculate the corresponding
current for a mesoscopic Fermi system in the partition-free setting. To this
end we study a small sample coupled to a finite number of semi-infinite leads.
Initially, the whole system of quasi-free fermions is in a grand canonical
equilibrium state. At t = 0 we turn on a potential bias on the leads and let
the system evolve. We study how the charge current behaves in time and how it
stabilizes itself around a steady state value, which is given by a
Landauer-type formula.

The CCAT-prime telescope is a 6-meter aperture, crossed-Dragone telescope,
designed for millimeter and sub-millimeter wavelength observations. It will be
located at an altitude of 5600 meters, just below the summit of Cerro
Chajnantor in the high Atacama region of Chile. The telescope's unobscured
optics deliver a field of view of almost 8 degrees over a large, flat focal
plane, enabling it to accommodate current and future instrumentation fielding
>100k diffraction-limited beams for wavelengths less than a millimeter. The
mount is a novel design with the aluminum-tiled mirrors nested inside the
telescope structure. The elevation housing has an integrated shutter that can
enclose the mirrors, protecting them from inclement weather. The telescope is
designed to co-host multiple instruments over its nominal 15 year lifetime. It
will be operated remotely, requiring minimum maintenance and on-site activities
due to the harsh working conditions on the mountain. The design utilizes
nickel-iron alloy (Invar) and carbon-fiber-reinforced polymer (CFRP) materials
in the mirror support structure, achieving a relatively temperature-insensitive
mount. We discuss requirements, specifications, critical design elements, and
the expected performance of the CCAT-prime telescope. The telescope is being
built by CCAT Observatory, Inc., a corporation formed by an international
partnership of universities. More information about CCAT and the CCAT-prime
telescope can be found at www.ccatobservatory.org.

A unified theory is outlined for the cuprates, Fe-based, and related
superconductors. Their low-energy excitations are approached in terms of
auxiliary particles representing combinations of atomic-like electron
configurations, and the introduction of a Lagrange Bose field enables their
treatment as bosons or fermions. This theory correctly describes the observed
phase diagram of the cuprates, including the non-Fermi-liquid to FL crossover
in the normal state, the existence of Fermi arcs below T^* and of "marginal-FL"
behavior above it. The anomalous behavior of numerous physical quantities is
accounted for, including kink- and waterfall-like spectral features, the drop
in the scattering rates below T^* and more radically below T_c, and an
effective increase in the density of carriers with T and \omega, reflected in
transport, optical and other properties. Also is explained the correspondence
between T_c, the resonance-mode energy, and the increase in the gap below T_c.

<br /><br />I saw once No Man's Land (1987) - IMDB link http://us.imdb.com/Title?0093638 - and found it ok. The film is about a guy who steals only Porsches. Gone in Sixty Seconds comes 13 years after and adds nothing to it. In fact, it has a lot of scenes that are worthless. And the ending is very, very bad.<br /><br />The Sphinx has a magnetic screen presence that should have been better used...

For many analytical problems the challenge is to handle huge amounts of
available data. However, there are data science application areas where
collecting information is difficult and costly, e.g., in the study of
geological phenomena, rare diseases, faults in complex systems, insurance
frauds, etc. In many such cases, generators of synthetic data with the same
statistical and predictive properties as the actual data allow efficient
simulations and development of tools and applications. In this work, we propose
the incorporation of Monte Carlo Dropout method within Autoencoder (MCD-AE) and
Variational Autoencoder (MCD-VAE) as efficient generators of synthetic data
sets. As the Variational Autoencoder (VAE) is one of the most popular generator
techniques, we explore its similarities and differences to the proposed
methods. We compare the generated data sets with the original data based on
statistical properties, structural similarity, and predictive similarity. The
results obtained show a strong similarity between the results of VAE, MCD-VAE
and MCD-AE; however, the proposed methods are faster and can generate values
similar to specific selected initial instances.

We study the nontrivial dispersion relation of mesons resulting from the
splitting of the transversal and longitudinal mesonic wave function
renormalizations, and its influences on the QCD phase transition, equation of
state, and the fluctuations of baryon number. The calculations are performed in
a two-flavor low energy effective model within the functional renormalization
group approach. We find that influences of the splitting mesonic wave function
renormalizations on the equilibrium thermodynamical bulk properties are mild.
Furthermore, we have compare the fixed and running expansion for the effective
potential in detail, through which the role of the field-dependent meson and
quark wave function renormalizations could be inferred.

The squeezing spectrum of the fluorescence field emitted from a four-level
atom in $J=1/2$ to $J=1/2$ configuration driven by two coherent fields is
studied. We find that the squeezing properties of the fluorescence radiation
are significantly influenced by the presence of vacuum-induced coherence in the
atomic system. It is shown that such coherence induces spectral squeezing in
phase quadratures of the fluorescence light for both weak and strong driving
fields. The dependence of the squeezing spectrum on the relative phase of the
driving fields is also investigated. Effects such as enhancement or suppression
of the squeezing peaks are shown in the spectrum as the relative phase is
varied. An analytical explanation of the numerical findings is presented using
dressed-states of the atom-field system.

We present the first fully relativistic study of gravitational radiation from
bodies in circular equatorial orbits around the massive black hole at the
Galactic Center, Sgr A* and we assess the detectability of various kinds of
objects by the gravitational wave detector LISA. Our computations are based on
the theory of perturbations of the Kerr spacetime and take into account the
Roche limit induced by tidal forces in the Kerr metric. The signal-to-noise
ratio in the LISA detector, as well as the time spent in LISA band, are
evaluated. We have implemented all the computational tools in an open-source
SageMath package, within the Black Hole Perturbation Toolkit framework. We find
that white dwarfs, neutrons stars, stellar black holes, primordial black holes
of mass larger than $10^{-4} M_\odot$, main-sequence stars of mass lower than
$\sim 2.5\, M_\odot$ and brown dwarfs orbiting Sgr A* are all detectable in one
year of LISA data with a signal-to-noise ratio above 10 during at least $10^5$
years in the slow inspiral towards either the innermost stable circular orbit
(compact objects) or the Roche limit (main-sequence stars and brown dwarfs).
The longest times in-band, of the order of $10^6$ years, are achieved for
primordial black holes of mass $\sim 10^{-3} M_\odot$ down to $10^{-5}
M_\odot$, depending on the spin of Sgr A*, as well as for brown dwarfs, just
followed by white dwarfs and low mass main-sequence stars. The long time
in-band of these objects makes Sgr A* a valuable target for LISA. We also
consider bodies on close circular orbits around the massive black hole in the
nucleus of the nearby galaxy M32 and find that, among them, compact objects and
brown dwarfs stay for $10^3$ to $10^4$ years in LISA band with a 1-year
signal-to-noise ratio above 10.

The security of cyber-physical systems, from self-driving cars to medical
devices, depends on their underlying multi-hop wireless networks. Yet, the lack
of trusted central infrastructures and limited nodes' resources make securing
these networks challenging. Recent works on key pre-distribution schemes, where
nodes communicate over encrypted overlay paths, provide an appealing solution
because of their distributed, computationally light-weight nature. Alas, these
schemes share a glaring security vulnerability: the two ends of every overlay
link can decrypt---and potentially modify and alter---the message. Plus, the
longer overlay paths impose traffic overhead and increase latency.
We present a novel routing mechanism, KPsec, to address these issues. KPsec
deploys multiple disjoint paths and an initial key-exchange phase to secure
end-to-end communications. After the initial key-exchange phase, traffic in
KPsec follows the shortest paths and, in contrast to key pre-distribution
schemes, intermediate nodes cannot decrypt it. We measure the security and
performance of KPsec as well as three state-of-the-art key pre-distribution
schemes using a real 10-node testbed and large-scale simulations. Our
experiments show that, in addition to its security benefits, KPsec results in
$5-15\%$ improvement in network throughput, up to $75\%$ reduction in latency,
and an order of magnitude reduction in energy consumption.

We propose an algorithm for finding overlapping community structure in very
large networks. The algorithm is based on the label propagation technique of
Raghavan, Albert, and Kumara, but is able to detect communities that overlap.
Like the original algorithm, vertices have labels that propagate between
neighbouring vertices so that members of a community reach a consensus on their
community membership. Our main contribution is to extend the label and
propagation step to include information about more than one community: each
vertex can now belong to up to v communities, where v is the parameter of the
algorithm. Our algorithm can also handle weighted and bipartite networks. Tests
on an independently designed set of benchmarks, and on real networks, show the
algorithm to be highly effective in recovering overlapping communities. It is
also very fast and can process very large and dense networks in a short time.

Sirencall, I don't think you are paying attention.
The indictments of Manafort (and the other guy; can't think of his name) are surely crimes, but nothing in the indictment indicates it has anything to do with the so-called "Russian Probe."
Bloomberg news did a story on the indictments this morning and reporter covering it said, allegations of crime, yes, allegations or Russian interference with the election, no.
The Mueller probe will find something - some crime. But it will not find anything with the Russians and the 2016 election, because there is nothing.
Just more fake news. (Sorry G&M - as I know you will delete my comment because I refer to what you report as Fake News.)

A unified chiral mean field approach is presented for QCD thermodynamics in a
wide range of temperatures and densities. The model simultaneously gives a
satisfactory description of lattice QCD thermodynamics and fulfills nuclear
matter and astrophysical constraints. The resulting equation of state can be
incorporated in relativistic fluid-dynamical simulations of heavy-ion
collisions and neutron stars mergers. Access to different regions of the QCD
phase diagram can be obtained in simulations of heavy-ion data and observations
of neutron star mergers.

We present the results on excimer laser modification and patterning of
amorphous vanadium pentoxide films. Wet positive resist-type and Ar ion-beam
negative resist-type etching techniques were employed to develop UV-modified
films. V2O5 films were found to possess sufficient resistivity compared to
standard electronic materials thus to be promising masks for sub-micron
lithog-raphy

We consider the problem of secure identification: user U proves to server S
that he knows an agreed (possibly low-entropy) password w, while giving away as
little information on w as possible, namely the adversary can exclude at most
one possible password for each execution of the scheme. We propose a solution
in the bounded-quantum-storage model, where U and S may exchange qubits, and a
dishonest party is assumed to have limited quantum memory. No other restriction
is posed upon the adversary.
An improved version of the proposed identification scheme is also secure
against a man-in-the-middle attack, but requires U and S to additionally share
a high-entropy key k. However, security is still guaranteed if one party loses
k to the attacker but notices the loss. In both versions of the scheme, the
honest participants need no quantum memory, and noise and imperfect quantum
sources can be tolerated. The schemes compose sequentially, and w and k can
securely be re-used.
A small modification to the identification scheme results in a
quantum-key-distribution (QKD) scheme, secure in the bounded-quantum-storage
model, with the same re-usability properties of the keys, and without assuming
authenticated channels. This is in sharp contrast to known QKD schemes (with
unbounded adversary) without authenticated channels, where authentication keys
must be updated, and unsuccessful executions can cause the parties to run out
of keys.

In this paper, we study the learning of safe policies in the setting of
reinforcement learning problems. This is, we aim to control a Markov Decision
Process (MDP) of which we do not know the transition probabilities, but we have
access to sample trajectories through experience. We define safety as the agent
remaining in a desired safe set with high probability during the operation
time. We therefore consider a constrained MDP where the constraints are
probabilistic. Since there is no straightforward way to optimize the policy
with respect to the probabilistic constraint in a reinforcement learning
framework, we propose an ergodic relaxation of the problem. The advantages of
the proposed relaxation are threefold. (i) The safety guarantees are maintained
in the case of episodic tasks and they are kept up to a given time horizon for
continuing tasks. (ii) The constrained optimization problem despite its
non-convexity has arbitrarily small duality gap if the parametrization of the
policy is rich enough. (iii) The gradients of the Lagrangian associated with
the safe-learning problem can be easily computed using standard policy gradient
results and stochastic approximation tools. Leveraging these advantages, we
establish that primal-dual algorithms are able to find policies that are safe
and optimal. We test the proposed approach in a navigation task in a continuous
domain. The numerical results show that our algorithm is capable of dynamically
adapting the policy to the environment and the required safety levels.

Context: Rapid rotation modifies the structure of the frequency spectrum of
pulsating stars, thus making mode identification difficult.
Aims: We look for new forms of organisation for the frequency spectrum that
can provide a basis for mode identification at high rotation rates.
Methods: Acoustic modes in uniformly rotating polytropic models of stars are
computed using a numerical code that fully takes the effects of rotation
(centrifugal distortion and Coriolis acceleration) into account. All low-degree
modes, l=0 to 3, with radial orders n=1-10 and 21-25 for N=3 polytropic models
and n=1-10 for N=1.5 polytropic models are followed from a zero rotation rate
up to 59 % of the break-up velocity.
Results: We find an empirical formula that gives a good description of the
high-frequency range of the computed acoustic spectrum for high rotation rates.
Differences between this formula and complete eigenmode calculations are shown
to be substantially smaller than those obtained with a third order perturbative
method valid at low rotation rates.

We classify different classes of entangled states arise in a two-qubit
system. Some of these classes are of Bell's state types, while others are of
the Werner's state types. The degree of entanglement is quantified for
different values of the atomic and the cavity parameters. We show that it is
possible to generate entangled state with high degree of entanglement by
controlling the detuning and the number of photon inside the cavity.

Early detection of person-to-person transmission of emerging infectious
diseases such as avian influenza is crucial for containing pandemics. We
developed a simple permutation test and its refined version for this purpose. A
simulation study shows that the refined permutation test is as powerful as or
outcompetes the conventional test built on asymptotic theory, especially when
the sample size is small. In addition, our resampling methods can be applied to
a broad range of problems where an asymptotic test is not available or fails.
We also found that decent statistical power could be attained with just a small
number of cases, if the disease is moderately transmissible between humans.

Existing solar energy application systems use small fraction of full spectrum
of solar energy. So attempts are made to show how full spectrum solar energy
can be used for diffused and beamed form of incident solar energy. Luminescent
Solar Concentrator (LSC) principle with optical fibre in diffused sun light and
dielectric mirror separation technique with optical fibre in beamed form are
discussed. Comparison of both the cases are done.
Keywords: full spectrum, solar photonics, diffused solar energy, beamed solar
energy, LSC, dielectric mirror, optical fibre, Photo-Voltaic

From analysis of the in-plane resistivity $\rho_{ab}(T)$ of
La$_{2-x}$Sr$_x$CuO$_4$, we show that normal state transport in overdoped
cuprates can be delineated into two regimes in which the electrical resistivity
varies approximately linearly with temperature. In the low temperature limit,
the $T$-linear resistivity extends over a very wide doping range, in marked
contrast to expectations from conventional quantum critical scenarios. The
coefficient of this $T$-linear resistivity scales with the superconducting
transition temperature $T_c$, implying that the interaction causing this
anomalous scattering is also associated with the superconducting pairing
mechanism. At high temperatures, the coefficient of the $T$-linear resistivity
is essentially doping independent beyond a critical doping $p_{\rm crit}$ =
0.19 at which the ratio of the two coefficients is maximal. Taking our cue from
earlier thermodynamic and photoemission measurements, we conclude that the
opening of the normal state pseudogap at $p_{\rm crit}$ is driven by the loss
of coherence of anti-nodal quasiparticles at low temperatures.

There exists a dichotomy between classical probabilistic graphical models,
such as Bayesian networks (BNs), and modern tractable models, such as
sum-product networks (SPNs). The former generally have intractable inference,
but provide a high level of interpretability, while the latter admits a wide
range of tractable inference routines, but are typically harder to interpret.
Due to this dichotomy, tools to convert between BNs and SPNs are desirable.
While one direction -- compiling BNs into SPNs -- is well discussed in
Darwiche's seminal work on arithmetic circuit compilation, the converse
direction -- decompiling SPNs into BNs -- has received surprisingly little
attention.
In this paper, we fill this gap by proposing SPN2BN, an algorithm that
decompiles an SPN into a BN. SPN2BN has several salient features when compared
to the only other two works decompiling SPNs. Most significantly, the BNs
returned by SPN2BN are minimal independence-maps that are more parsimonious
with respect to the introduction of latent variables. Secondly, the output BN
produced by SPN2BN can be precisely characterized with respect to a compiled
BN. More specifically, a certain set of directed edges will be added to the
input BN, giving what we will call the moral-closure. Lastly, it is established
that our compilation-decompilation process is idempotent. This has practical
significance as it limits the size of the decompiled SPN.

Market research is generally performed by surveying a representative sample
of customers with questions that includes contexts such as psycho-graphics,
demographics, attitude and product preferences. Survey responses are used to
segment the customers into various groups that are useful for targeted
marketing and communication. Reducing the number of questions asked to the
customer has utility for businesses to scale the market research to a large
number of customers. In this work, we model this task using Bayesian networks.
We demonstrate the effectiveness of our approach using an example market
segmentation of broadband customers.

Frustrated and disappointed
I'm giving this book three stars because it had some good points but in the end it was a depressing story and left me frustrated. The back and forth, bad decisions made repeatedly, and amount of time that the two main characters longed for each other was too much and then the ending was rushed. I've loved this author in the past so I didn't even question purchasing this book on the first day of it's release but was disappointed in the end.

Color fades
Love these sunglasses! Love the lenses and the comfort of them... The only reason these are getting 3 stars is because of how badly the front of the frames faded. They started as this beautiful teal color, and now they are a pale yellow/brown color. I miss how pretty they used to be.

Didn't work for my Light setup
I'm not going to give this Item a bad review because I could have just received a bad pair. I followed the directions provided to a T and I could not get these bulbs to work. After returning them I went to Batteries + bulbs and bought a set and the worked perfect right off the shelf. These bulbs require you to remove the ballast and run hot to one end of the bulb and Neutral to the other. They didn't work for me. Good luck

We study the problem of searching for and tracking a collection of moving
targets using a robot with a limited Field-Of-View (FOV) sensor. The actual
number of targets present in the environment is not known a priori. We propose
a search and tracking framework based on the concept of Bayesian Random Finite
Sets (RFSs). Specifically, we generalize the Gaussian Mixture Probability
Hypothesis Density (GM-PHD) filter which was previously applied for tracking
problems to allow for simultaneous search and tracking with a limited FOV
sensor. The proposed framework can extract individual target tracks as well as
estimate the number and the spatial density of targets. We also show how to use
the Gaussian Process (GP) regression to extract and predict non-linear target
trajectories in this framework. We demonstrate the efficacy of our techniques
through representative simulations and a real data collected from an aerial
robot.

Helps me stay regular
I do have rheumatoid arthritis and I heard it's good for that, but I honestly can't tell anything other than fish oil supplements working for my joints. This does, however, keep me regular in conjunction with vitamin C. I take a heaping tablespoon of this mixed with a glass of water every morning about 30 minutes before I eat, and the vitamin C, I take at night. If the powdery taste bothers you, I recommend using a straw. It goes down pretty easy that way. One thing that does bother me is the packaging. The powder clogs the part of the bag that zips close, and I can't seal it, so I have to use a clip to keep it shut. The product itself is great.

This study seeks to improve the running time of the Local Directional Pattern
(LDP) during feature extraction using a newly proposed acceleration scheme to
LDP. LDP is considered to be computationally expensive. To confirm this, the
running time of the LDP to gray level co-occurrence matrix (GLCM) were it was
established that the running time for LDP was two orders of magnitude higher
than that of the GLCM. In this study, the performance of the newly proposed
acceleration scheme was evaluated against LDP and Local Binary patter (LBP)
using images from the publicly available extended Cohn-Kanade (CK+) dataset.
Based on our findings, the proposed acceleration scheme significantly improves
the running time of the LDP by almost 3 times during feature extraction
