We present ALMA and MUSE observations of the Brightest Cluster Galaxy in
Abell 2597, a nearby (z=0.0821) cool core cluster of galaxies. The data map the
kinematics of a three billion solar mass filamentary nebula that spans the
innermost 30 kpc of the galaxy's core. Its warm ionized and cold molecular
components are both cospatial and comoving, consistent with the hypothesis that
the optical nebula traces the warm envelopes of many cold molecular clouds that
drift in the velocity field of the hot X-ray atmosphere. The clouds are not in
dynamical equilibrium, and instead show evidence for inflow toward the central
supermassive black hole, outflow along the jets it launches, and uplift by the
buoyant hot bubbles those jets inflate. The entire scenario is therefore
consistent with a galaxy-spanning "fountain", wherein cold gas clouds drain
into the black hole accretion reservoir, powering jets and bubbles that uplift
a cooling plume of low-entropy multiphase gas, which may stimulate additional
cooling and accretion as part of a self-regulating feedback loop. All
velocities are below the escape speed from the galaxy, and so these clouds
should rain back toward the galaxy center from which they came, keeping the
fountain long-lived. The data are consistent with major predictions of chaotic
cold accretion, precipitation, and stimulated feedback models, and may trace
processes fundamental to galaxy evolution at effectively all mass scales.

We consider two-dimensional non-centrosymmetric superconductors, where the
order parameter is a mixture of s-wave and p-wave parts, in the presence of an
externally induced Zeeman splitting. We derive the conditions under which the
system is in a non-Abelian phase. By considering the non-degenerate zero-energy
Majorana solutions of the Bogoliubov-de Gennes (BdG) equations for a vortex and
by constructing a topological invariant, we show that the condition for the
non-Abelian phase to exist is completely independent of the triplet pairing
amplitude. The existence condition for the non-Abelian phase derived from the
real space solutions of the BdG equations involves the Pfaffian of the BdG
Hamiltonian at k = 0, which is completely insensitive to the magnitude of the
p-wave component of the order parameter. We arrive at the same conclusion by
using the appropriate topological invariant for this case. This is in striking
contrast to the analogous condition for the time-reversal invariant topological
phases, in which the amplitude of the p-wave component must be larger than the
amplitude of the s-wave piece of the order parameter. As a by-product, we
establish the intrinsic connection between the Pfaffian of the BdG Hamiltonian
at k = 0 (which arises at the BdG approach) and the relevant Z topological
invariant.

A family $\F$ of sets is said to be intersecting if any two sets in $\F$ have
nonempty intersection. The celebrated Erd{\H o}s-Ko-Rado theorem determines the
size and structure of the largest intersecting family of $k$-sets on an $n$-set
$X$. An $(s,t)$-union intersecting family is a family of $k$-sets on an $n$-set
$X$ such that for any $A_1,\ldots,A_{s+t}$ in this family,
$\left(\cup_{i=1}^sA_i\right)\cap\left(\cup_{i=1}^t A_{i+s}\right)\neq
\varnothing.$ Let $\ell(\F)$ be the minimum number of sets in $\F$ such that by
removing them the resulting subfamily is intersecting. In this paper, for
sufficiently large $n$, we characterize the size and structure of $(s,t)$-union
intersecting families with maximum possible size and $\ell(\F)\geq s+\beta$.
This allows us to find out the size and structure of some large and maximal
$(s,t)$-union intersecting families.
Our results are nontrivial extensions of some recent generalizations of the
Erd{\H o}s-Ko-Rado theorem such as the Han and Kohayakawa theorem 2017 which
finds the structure of the third largest intersecting family, the Kostochka and
Mubayi theorem 2017, and the more recent Kupavskii's theorem 2018 whose both
results determine the size and structure of the $i$th largest intersecting
family of $k$-sets for $i\leq k+1$. In particular, we prove that a
Hilton-Milner-type stability theorem holds for $(1,t)$-union intersecting
families, that indeed, confirms a conjecture of Alishahi and Taherkhani 2018.
We extend our results to $K_{s_1,\ldots,s_{r+1}}$-free subgraphs of Kneser
graphs. In fact, when $n$ is sufficiently large, we characterize the size and
structure of large and maximal $K_{s_1,\ldots,s_{r+1}}$-free subgraphs of
Kneser graphs. In particular, when $s_1=\cdots=s_{r+1}=1$ our result provides
some stability results related to the famous Erd{\H o}s matching conjecture.

The show is about two sisters living together. Holly being the younger one has some teenage problems on the other hand her sister Val has job,boy friend,fiancé problems like most of the women on the planet. They try to support each other they make mistakes sometimes but they don't give up and continue. And the show is also about friendship. The priorities in life. I loved this show so much. It is funny and the actors are so good. I am really sad that the show is over. I still watch the reruns time to time:) Amanda Bynes is very talented. Jenny Garth may be new to comedy but she plays really well. She is one of the actresses i like watching. I like Vince and Holly's relationship they are very natural. Gary is a natural talent and makes you laugh each time he shows up. With Tina Holly found a real friend and i really like them hanging out. Lauren character is so funny and she is a natural talent. I would like to see her more. This show really takes you in and makes you laugh. I wish the show hasn't been over.

Acoustic cloaking for the suppression of backscattering inside ducts is
proposed in the audible range where plane waves are curved around the object
using the surface modes of the liner. It is numerically shown that a slowly
varying resonant liner (e. g. based on an array of tubes) creates a zone of
silence in which an object of arbitrary shape can be acoustically hidden for a
wide range of frequencies. And then, a resonant liner has deflecting properties
without reflection of the wavefront, which are close to an ideal invisibility
cloak. This kind of cloaking is effective in a wide frequency band and the
cloaking band is a function of the impedance and height of the obstacle
relative to the conduit. For smooth shaped obstacles, there is an ability of
the object to help hide itself, which increases the cloaking frequency band
(self-cloaking). Dispersion effects lead to slow sounds and distortion of the
wave phase.

Judge Trader is going to order that Oki pay restitution however on release from prison, it is likely
he will end up paying back just a very small fraction of what he stole. In the event he elects to serve out his
entire 10 year sentence, he will not have to pay any of the restitution. Sweet yeah.
Unfortunately, unless his former partners initiate civil action to seize all of his assets, they are going to
get bumpkus. Our laws regarding paying restitution in criminal cases are a joke and totally favor the
offender. The victims get the shaft big time.

Scant back-head coverage
Looking at the photos posted (making the mask look almost like a pseudo motorcycle helmet, I assumed this covered nearly the entire back of the head. It doesn't. Nearly the entirety of the back of the wearer's head is exposed. One another matter...the size. I don't know who has a head the size of this mask. Maybe a jacked-up professional wrestler. It's loose; the sides don't adhere to the sides of my face...and there's no way of tightening it. I bought the mask for a video shoot...so perhaps it will fit the model better than me. But my first impression...due to the lack of back of head coverage is massive disappointment.

Generic visual tracking is difficult due to many challenge factors (e.g.,
occlusion, blur, etc.). Each of these factors may cause serious problems for a
tracking algorithm, and when they work together can make things even more
complicated. Despite a great amount of efforts devoted to understanding the
behavior of tracking algorithms, reliable and quantifiable ways for studying
the per factor tracking behavior remain barely available. Addressing this
issue, in this paper we contribute to the community a tracking diagnosis
toolkit, TracKlinic, for diagnosis of challenge factors of tracking algorithms.
TracKlinic consists of two novel components focusing on the data and analysis
aspects, respectively. For the data component, we carefully prepare a set of
2,390 annotated videos, each involving one and only one major challenge factor.
When analyzing an algorithm for a specific challenge factor, such
one-factor-per-sequence rule greatly inhibits the disturbance from other
factors and consequently leads to more faithful analysis. For the analysis
component, given the tracking results on all sequences, it investigates the
behavior of the tracker under each individual factor and generates the report
automatically. With TracKlinic, a thorough study is conducted on ten
state-of-the-art trackers on nine challenge factors (including two compound
ones). The results suggest that, heavy shape variation and occlusion are the
two most challenging factors faced by most trackers. Besides, out-of-view,
though does not happen frequently, is often fatal. By sharing TracKlinic, we
expect to make it much easier for diagnosing tracking algorithms, and to thus
facilitate developing better ones.

Distributed machine learning (ML) systems today use an unsophisticated threat
model: data sources must trust a central ML process. We propose a brokered
learning abstraction that allows data sources to contribute towards a
globally-shared model with provable privacy guarantees in an untrusted setting.
We realize this abstraction by building on federated learning, the state of the
art in multi-party ML, to construct TorMentor: an anonymous hidden service that
supports private multi-party ML.
We define a new threat model by characterizing, developing and evaluating new
attacks in the brokered learning setting, along with new defenses for these
attacks. We show that TorMentor effectively protects data providers against
known ML attacks while providing them with a tunable trade-off between model
accuracy and privacy. We evaluate TorMentor with local and geo-distributed
deployments on Azure/Tor. In an experiment with 200 clients and 14 MB of data
per client, our prototype trained a logistic regression model using stochastic
gradient descent in 65s.

Given an isoparametric function $f$ on the $n$-dimensional sphere, we
consider the space of functions $w\circ f$ to reduce the Yamabe equation on the
round sphere into a singular ODE on $w$ in the interval $[0,\pi]$, of the form
$w" + (h(r)/\sin r)w'+\lambda(\vert w\vert^{4/n-2}w - w)=0$, where $h$ is a
monotone function with exactly one zero on $[0,\pi]$ and $\lambda>0$ is a
constant. The natural boundary conditions in order to obtain smooth solutions
are $w'(0)=0$ and $w'(\pi )=0$. We show that for any positive integer $k$ there
exists a solution with exactly $k$-zeroes yielding solutions to the Yamabe
equation with exactly $k$ connected isoparametric hypersurfaces as nodal set.
The idea of the proof is to consider the initial value problems on both
singularities $0$ and $\pi$, and then to solve the corresponding double
shooting problem, matching the values of $w$ and $w'$ at the unique zero of
$h$. In particular we obtain solutions with exactly one zero, providing
solutions of the Yamabe equation with low energy, which can be computed easily
by numerical methods.

The paper is mainly devoted to the irreducibility of the polynomial
representation of the double affine Hecke algebra for an arbitrary reduced root
systems and generic "central charge" q. The technique of intertwiners in the
non-semisimple variant is the main tool. We introduce Macdonald's
non-semisimple polynomials and use them to analyze the reducibility of the
polynomial representation in terms of the affine exponents, counterparts of the
classical Coxeter exponents. The focus is on the principal aspects of the
technique of intertwiners, including related problems in the theory of reduced
decompositions on affine Weyl groups.

New observations of GD 99 are analysed. The unusual pulsation behaviour,
showing both long and short periods, has been confirmed. All the available
periods show a grouping of short and long period modes with roughly regular
spacing. If we interpret the groups separately, a binary nature can be a
possible explanation as in the similar cases of WD 2350-0054 and G29-38.

Are geometrical summaries of the CMB and LSS sufficient for estimating
cosmological parameters? And how does our choice of a dark energy model impact
the current constraints on standard cosmological parameters?
We address these questions in the context of the widely used CPL
parametrization of a time varying equation of state w in a cosmology allowing
spatial curvature. We study examples of different behavior allowed in a CPL
parametrization in a phase diagram, and relate these to effects on the
observables. We examine parameter constraints in such a cosmology by combining
WMAP5, SDSS, SNe, HST data sets by comparing the power spectra. We carefully
quantify the differences of these constraints to those obtained by using
geometrical summaries for the same data sets.
We find that (a) using summary parameters instead of the full data sets give
parameter constraints that are similar, but with discernible differences, (b)
due to degeneracies, the constraints on the standard parameters broaden
significantly for the same data sets. In particular, we find that in the
context of CPL dark energy, (i) a Harrison-Zeldovich spectrum cannot be ruled
out at $2\sigma$ levels with our current data sets. and (ii) the SNe IA, HST,
and WMAP 5 data are not sufficient to constrain spatial curvature; we
additionally require the SDSS DR4 data to achieve this.

I report recent results on the kinematics of the inner few hundred parsecs
(pc) around nearby active galactic nuclei (AGN) at a sampling of a few pc to a
few tens of pc, using optical and near-infrared (near-IR) integral field
spectroscopy obtained with the Gemini telescopes. The stellar kinematics of the
hosts - comprised mostly of spiral galaxies - are dominated by circular
rotation in the plane of the galaxy. Inflows with velocities of ~ 50 km/s have
been observed along nuclear spiral arms in (optical) ionized gas emission for
low-luminosity AGN and in (near-IR) molecular gas emission for
higher-luminosity AGN. We have also observed gas rotating in the galaxy plane,
sometimes in compact (few tens of pc) disks which may be fuelling the AGN.
Outflows have been observed mostly in ionized gas emission from the narrow-line
region, whose flux distributions and kinematics frequently correlate with radio
flux distributions. Channel maps along the emission-line profiles reveal
velocities as high as ~ 600 km/s. Mass outflow rates in ionized gas range from
0.01 to 0.001 solar masses per year and are 10-100 times larger than the mass
accretion rates to the AGN, supporting an origin for the bulk of the outflow in
gas from the galaxy plane entrained by a nuclear jet or accretion disk wind.

A doubly CKM-suppressed amplitude in $B^0\to J/\psi K_S$ leads to corrections
in CP asymmetries $S = \sin 2\beta, C=0$, which may be enhanced by
long-distance rescattering. It has been suggested that this enhancement may
lead to several percent corrections. We calculate an upper bound of order
$10^{-3}$ on rescattering corrections using measured branching ratios for
charmless $|\Delta S|=1$ $B^0$ decays.

Let G be a torsion--free abelian group of finite rank. The automorphism group
Aut(G) acts on the set of maximal independent subsets of G. The orbits of this
action are the isomorphism classes of indecomposable decompositions of G. G
contains a direct sum of strongly indecomposable groups as a characteristic
subgroup of finite index, giving rise to a classification of finite rank
strongly indecomposable torsion--free abelian groups.

Many clinical datasets are intrinsically imbalanced, dominated by overwhelming majority groups. Off-the-shelf machine learning models that optimize the prognosis of majority patient types (e.g., healthy class) may cause substantial errors on the minority prediction class (e.g., disease class) and demographic subgroups (e.g., Black or young patients). For example, our work found that missed death cases are 3.14 times higher than missed survival cases in a mortality prediction model. In the typical one-machine-learning-model-fits-all paradigm, racial and age disparities are likely to exist, but unreported. What makes it worse is the deceptive nature of widely used whole-population metrics, such as AUC-ROC. We show that some metrics fail to reflect serious prediction deficiencies. To mitigate representational biases, we design a double prioritized (DP) bias correction technique. Our method trains customized models for specific ethnicity or age groups, a substantial departure from the one-model-predicts-all convention. We report our findings on four prognosis tasks over two imbalanced clinical datasets. DP reduces relative disparities among race and age groups, 5.6% to 86.8% better than the 8 existing sampling solutions being compared, in terms of the minority class' recall.

We report on a scheme for the creation of time-bin entangled states out of
two subsequent single photons. Both photons arrive on the same input port of a
beamsplitter and the situation in which the photons leave the beamsplitter on
different output ports is post-selected. We derive a full quantum mechanical
analysis of such time-bin entanglement for emitters subject to uncorrelated
dephasing processes and apply this model to sequential single photons emerging
from a single semiconductor quantum dot. Our results indicate that the
visibility of entanglement is degraded by decoherence effects in the quantum
dot, but can be restored by use of CQED effects, namely the Purcell effect.

This is my second replacement box. I purchased my 1st box at the local big box retailer in Jan 2018. It started to crack in the back within 2 months. Later, while loading it in my service van. The handle came off. The lid is cracking in the corners now. I e-mailed Dewalt customer service and I have to ship that box to Mississippi for evaluation. So now I ordered a 2nd tool box and, I have to have it because I repair refrigerators in customers homes. The tool box is great because it keeps everything together and saves trips to the service van. But this box is fragile. I worried a bit when I received the 2nd box. The shipping was pretty fast but no packing materials in a oversized box. Luckily it didn’t get damaged.

The human-machine interface is of critical importance for master-slave
control of the robotic system for surgery, in which current systems offer the
control or two robotic arms teleoperated by the surgeon's hands. To relax the
need for surgical assistants and augment dexterity in surgery, it has been
recently proposed to use a robot like a third arm that can be controlled
seamlessly, independently from the natural arms, and work together with them.
This report will develop and investigate this concept by implementing foot
control of a robotic surgical arm. A novel passive haptic foot-machine
interface system and analysis of its performances were introduced in this
report. This interface using a parallel-serial hybrid structure with springs
and force sensors, which allows intuitive control of a slave robotic arm with
four degrees of freedom (dof). The elastic isometric design enables a user to
control the interface system accurately and adaptively, with an enlarged
sensing range breaking the physical restriction of the pedal size. A subject
specific (independent component analysis, ICA) model is identified to map the
surgeon's foot movements into kinematic parameters of the slave robotic arm. To
validate the system and assess the performance it allows, 10 subjects carried
out experiments to manipulate the foot-machine interface system in various
movements. With these experimental data, the mapping models were built and
verified. A comparison between different mapping models was made and analyzed
proving the ICA algorithm is obviously dominant over other methods.

We prove that second-order hyperbolic Monge-Ampere equations for one function
of two variables are connected to the wave equation by a Backlund
transformation if and only if they are integrable by the method of Darboux at
second order. One direction of proof, proving Darboux integrability, follows
the implications of the wave equation for the invariants of the G-structure
associated to the Backlund transformation. The other direction constructs
Backlund transformations for Darboux integrable equations as solutions of an
involutive exterior differential system. Explicit transformations are given for
several equations on the Goursat-Vessiot list of Darboux-integrable equations.

The transformation from angle-action variables to Cartesian coordinates is a
crucial step of the (semi) classical description of bimolecular collisions and
photo-fragmentations. The basic reason is that dynamical conditions
corresponding to experiments are ideally generated in angle-action variables
whereas the classical equations of motion are ideally solved in Cartesian
coordinates by standard numerical approaches. To our knowledge, the previous
transformation is available in the literature only for triatomic systems. The
goal of the present work is to derive it for polyatomic ones.

Whether it be in normal form games, or in fair allocations, or in voter
preferences in voting systems, a certain pattern of reasoning is common. From a
particular profile, an agent or a group of agents may have an incentive to
shift to a new one. This induces a natural graph structure that we call the
improvement graph on the strategy space of these systems. We suggest that the
monadic fixed-point logic with counting, an extension of monadic first-order
logic on graphs with fixed-point and counting quantifiers, is a natural
specification language on improvement graphs, and thus for a class of
properties that can be interpreted across these domains. The logic has an
efficient model checking algorithm (in the size of the improvement graph).

Cannot use this compost bucket without a bag
We were excited when this product arrived as it is certainly made of durable plastic but the "bucket" that holds the compost material is not solid (it has venting holes all along the bottom rim) and therefore, this product cannot be used without a plastic bag inserted. Since the supplied compost-able bags are NOT recommended for home composting, this renders this product unusable for home composting as there is no way to store your materials before dumping them into your garden/outdoor compost bin where plastic "compost-able" bags are NOT acceptable. Very disappointed in the design of this product.

The set A of nonnegative integers is called a basis of order h if every
nonnegative integer can be represented as the sum of exactly h not necessarily
distinct elements of A. An additive basis A of order h is called thin if there
exists c > 0 such that the number of elements of A not exceeding x is less than
cx^{1/h} for all x > 0. This paper describes a construction of Shatrovskii of
thin bases of order h.

In recent years, hyper-complex deep networks (such as complex-valued and
quaternion-valued neural networks) have received a renewed interest in the
literature. They find applications in multiple fields, ranging from image
reconstruction to 3D audio processing. Similar to their real-valued
counterparts, quaternion neural networks (QVNNs) require custom regularization
strategies to avoid overfitting. In addition, for many real-world applications
and embedded implementations, there is the need of designing sufficiently
compact networks, with few weights and neurons. However, the problem of
regularizing and/or sparsifying QVNNs has not been properly addressed in the
literature as of now. In this paper, we show how to address both problems by
designing targeted regularization strategies, which are able to minimize the
number of connections and neurons of the network during training. To this end,
we investigate two extensions of l1 and structured regularization to the
quaternion domain. In our experimental evaluation, we show that these tailored
strategies significantly outperform classical (real-valued) regularization
approaches, resulting in small networks especially suitable for low-power and
real-time applications.

No Bender, too many crappy logos.
Didn't get many of the stickers in the product picture. Stickers are matte, not shiny/slick. Unhappy with Obama fascism sticker and I'm not sure why there are so many product logos. Pringles, YouTube, Coca-Cola, The Discovery Channel??? If you're looking to just fill up as much space as possible and don't really care about what it's with then this sticker pack is for you. I guess I'm cool enough for it though, I don't know what most of the designs mean.

Electromagnetic observations over the last 15 years have yielded a growing
appreciation for the importance of supermassive black holes (SMBH) to the
evolution of galaxies, and for the intricacies of dynamical interactions in our
own Galactic center. Here we show that future low-frequency gravitational wave
observations, alone or in combination with electromagnetic data, will open up
unique windows to these processes. In particular, gravitational wave detections
in the 10^{-5}-10^{-1} Hz range will yield SMBH masses and spins to
unprecedented precision and will provide clues to the properties of the
otherwise undetectable stellar remnants expected to populate the centers of
galaxies. Such observations are therefore keys to understanding the interplay
between SMBHs and their environments.

Zero-shot text classification (0Shot-TC) is a challenging NLU problem to
which little attention has been paid by the research community. 0Shot-TC aims
to associate an appropriate label with a piece of text, irrespective of the
text domain and the aspect (e.g., topic, emotion, event, etc.) described by the
label. And there are only a few articles studying 0Shot-TC, all focusing only
on topical categorization which, we argue, is just the tip of the iceberg in
0Shot-TC. In addition, the chaotic experiments in literature make no uniform
comparison, which blurs the progress.
This work benchmarks the 0Shot-TC problem by providing unified datasets,
standardized evaluations, and state-of-the-art baselines. Our contributions
include: i) The datasets we provide facilitate studying 0Shot-TC relative to
conceptually different and diverse aspects: the ``topic'' aspect includes
``sports'' and ``politics'' as labels; the ``emotion'' aspect includes ``joy''
and ``anger''; the ``situation'' aspect includes ``medical assistance'' and
``water shortage''. ii) We extend the existing evaluation setup
(label-partially-unseen) -- given a dataset, train on some labels, test on all
labels -- to include a more challenging yet realistic evaluation
label-fully-unseen 0Shot-TC (Chang et al., 2008), aiming at classifying text
snippets without seeing task specific training data at all. iii) We unify the
0Shot-TC of diverse aspects within a textual entailment formulation and study
it this way.

In this paper, we study the parameter synthesis problem for a class of
parametric timed automata. The problem asks to construct the set of valuations
of the parameters in the parametric timed automa- ton, referred to as the
feasible region, under which the resulting timed automaton satisfies certain
properties. We show that the parameter syn- thesis problem of parametric timed
automata with only one parametric clock (unlimited concretely constrained
clock) and arbitrarily many pa- rameters is solvable when all the expressions
are linear expressions. And it is moreover the synthesis problem is solvable
when the form of con- straints are parameter polynomial inequality not just
simple constraint and parameter domain is nonnegative real number.

We solve the discrete Hirota equations (Kirillov-Reshetikhin Q-systems) for
$A_r$, and their analogue for $D_r$, for the cases where the second variable
ranges over either a finite set or over all integers. Until now only special
solutions were known. We find all solutions for which no component vanishes, as
required in the known applications. As an introduction we present the known
solution where the second variable ranges over the natural numbers.

My toddlers love this!
My twin two year olds love detailed toys where they have to put things together and this was perfect! It entertains them and they can work on their coordination with smaller objects. Very easy to use. They try to stack them all in a straight line and have a blast seeing how high they can get

It's funny. I've seen a bunch of Fassbinder films and I have found some to be extremely creative and interesting, while others are repellent and self-indulgent messes--like this film. For me, it ranges from great to crap--without much in the middle. I know he has a lot of fans among the "sophisticated", but I can't help but think that a lot of his appeal is pure hype. From my point of view (and I know I will get a lot of negative ratings for this), he made too many movies too quickly and was too self-indulgent. His gay or gender-bending films (like this one) tend to be really bad--sloppily done, sometimes quite boring (such as QUERELLE and THE BITTER TEARS OF PETRA VON KANT) and sometimes just gross (like this film). Couldn't his message about acceptance of a person's gender-confusion be handled better than showing him get slapped around or watching cows being gruesomely slaughtered? Show some sensitivity for the subject matter and make your characters more human and sympathetic--then, maybe, I'd care about the films. <br /><br />I'm honestly at the point after watching this film that I might not bother with any more Fassbinder films--the bad seems to be out-weighing the good.

We algebraically compute all possible sectional curvature values for
canonical algebraic curvature tensors, and use this result to give a method for
constructing general sectional curvature bounds. We use a well-known method to
geometrically realize these results to produce a hypersurface with prescribed
sectional curvatures at a point. By extending our methods, we give a relatively
short proof of the Spectral Theorem for self-adjoint operators on a finite
dimensional real vector space.

It has been suggested that, considering channeling effect, the order of a few
GeV dark matters which are elastically scattered from detector nuclei might be
plausible candidates reconciling the DAMA annual modulation signal with the
results of other null experiments. We show that Singlet Fermionic Dark Matter
can be such a dark matter candidate, simultaneously providing the correct
thermal relic density which is consistent with the WMAP data.

Well... University of Alabama, who (apparently) has a mildly successful football team is the fastest growing state flagship university in the country.
They saw a 58% increase in enrollment between 2006 and 2016. The students choosing to attend also got better: Their average GPA was 3.66 vs. 3.4. The top quarter scored a 31 or better on the ACT, up from 27. Only 43% of students are from in state.
Also, the football team was pretty good during that decade.
No, most athletic programs are not self-supporting, but Oregon's is. And, like Alabama, Oregon's athletes draw students to the school.

The coded caching scheme proposed by Maddah-Ali and Niesen (MAN) transmits
coded multicast messages to users equipped with caches and it is known to be
optimal within a constant factor. This work extends this caching scheme to
two-hop relay networks with one main server with access to a library of $N$
files, and $H$ relays communicating with $K$ users with cache, each of which is
connected to a random subset of relays. This topology can be considered as a
generalized version of a celebrated family of networks, referred to as
combination networks. Our approach is simply based on routing MAN packets
through the network. The optimization of the routing can be formulated as a
Linear Program (LP). In addition, to reduce the computation complexity, a
dynamic algorithm is proposed to approach the LP solution. Numerical
simulations show that the proposed scheme outperforms the existing caching
schemes for this class of networks.

Received Soiled Curtains
Have tried to leave seller feedback twice & it is not registering, so a review will have to do. Ordered 4 panels. Three of them were soiled-not just in one spot, but throughout & one had a small hole. These had to be ironed & my old curtains taken down so it was not worth the hassle of returning them. Someone commented, "You get what you pay for." Yes, these were inexpensive. I accepted that the stitching was irregular on some of the seams, & even accepted the hole. What is not acceptable is receiving soiled items at any price.

This is the second in a series of papers intended to provide a basic overview
of some of the major ideas in particle physics. Part I [arXiv:0810.3328] was
primarily an algebraic exposition of gauge theories. We developed the group
theoretic tools needed to understand the basic construction of gauge theory, as
well as the physical concepts and tools to understand the structure of the
Standard Model of Particle Physics as a gauge theory.
In this paper (and the paper to follow), we continue our emphasis on gauge
theories, but we do so with a more geometrical approach. We will conclude this
paper with a brief discussion of general relativity, and save more advanced
topics (including fibre bundles, characteristic classes, etc.) for the next
paper in the series.
We wish to reiterate that these notes are not intended to be a comprehensive
introduction to any of the ideas contained in them. Their purpose is to
introduce the "forest" rather than the "trees". The primary emphasis is on the
algebraic/geometric/mathematical underpinnings rather than the
calculational/phenomenological details. The topics were chosen according to the
authors' preferences and agenda.
These notes are intended for a student who has completed the standard
undergraduate physics and mathematics courses, as well as the material
contained in the first paper in this series. Having studied the material in the
"Further Reading" sections of would be ideal, but the material in this series
of papers is intended to be self-contained, and familiarity with the first
paper will suffice.

Quantum key distribution provides secure keys resistant to code-breaking
quantum computers. The continuous-variable version of quantum key distribution
offers the advantages of higher secret key rates in metropolitan areas, as well
as the use of standard telecom components that can operate at room temperature.
However, the transmission distance of these systems (compared with
discrete-variable systems) are currently limited and considered unsuitable for
long-distance distribution. Herein, we report the experimental results of long
distance continuous-variable quantum key distribution over 202.81 km of
ultralow-loss optical fiber by suitably controlling the excess noise and
employing highly efficient reconciliation procedures. This record-breaking
implementation of the continuous-variable quantum key distribution doubles the
previous distance record and shows the road for long-distance and large-scale
secure quantum key distribution using room-temperature standard telecom
components.

The super sexy B movie actress has another bit part as future "Goodfellas" star Ray Liotta's girlfriend in this box office bomb. She plays Marion, has only one line of dialog, well, one WORD of dialog actually. She shouts out "Joe!" as Ray's character is violating poor Pia Zadora with a plastic garden hose sprinkler. This movie is so bad though it becomes funny, hilarious at times. The guys at Mystery Science Theater 3000 would love this! Check out the hysterical scene at the end where Pia has a nervous breakdown and all the cheesy editing and effects they do to try and show how badly Pia's character is freaking out. Pia plays an aspiring Hollywood screenwriter in this. Pia Zadora as a screenwriter? Yeah, right. Pia can barely talk, let alone write! Pia is utterly and absolutely miscast in this dumb role. But who cares? The real star is the hot and fresh Glory Annen in her bit part in this cat's opinion! Rock on Glory!

Many learning algorithms have invariances: when their training data is
transformed in certain ways, the function they learn transforms in a
predictable manner. Here we formalize this notion using concepts from the
mathematical field of category theory. The invariances that a supervised
learning algorithm possesses are formalized by categories of predictor and
target spaces, whose morphisms represent the algorithm's invariances, and an
index category whose morphisms represent permutations of the training examples.
An invariant learning algorithm is a natural transformation between two
functors from the product of these categories to the category of sets,
representing training datasets and learned functions respectively. We
illustrate the framework by characterizing and contrasting the invariances of
linear regression and ridge regression.

Over the past few years significant progress has been made in the field of
presentation attack detection (PAD) for automatic speaker recognition (ASV).
This includes the development of new speech corpora, standard evaluation
protocols and advancements in front-end feature extraction and back-end
classifiers. The use of standard databases and evaluation protocols has enabled
for the first time the meaningful benchmarking of different PAD solutions. This
chapter summarises the progress, with a focus on studies completed in the last
three years. The article presents a summary of findings and lessons learned
from two ASVspoof challenges, the first community-led benchmarking efforts.
These show that ASV PAD remains an unsolved problem and that further attention
is required to develop generalised PAD solutions which have potential to detect
diverse and previously unseen spoofing attacks.

Wow and I thought that any Steven Segal movie was bad. Every time I thought that the movie couldn't get worse it proved me wrong. The story was good but the actors couldn't carry it off. Also, they made a lot of mistakes on how proper archiological digs are done. For instance you don't handle artifacts untill they are catologed and accounted for. The biggest crime in casting was the archiologist girl. She is a weak actress and I felt that her acting really made the movie less realistic then it already was. The whole concept of the knights templar being underground all these years seemed pretty stupid to me. I like the idea of how they disappeared and stuff, so that almost seemed depressing. I thought that the characters wern't explained well enough. You didn't find out much background and that made it harder to relate to them.

Love this!!
This shipment came fast! These are NOT knockoffs. They are manufactured under license that allows use of the PARKER brand & logo, according to Parker specs. They write great and feel great while hand writing. I usually only use CROSS Classic, but I plan to give them a rest and go with these for every day carry in my shirt pocket. If the cartridges leak, I'll let you know. Can't beat the price!!!

Planning has achieved significant progress in recent years. Among the various
approaches to scale up plan synthesis, the use of macro-actions has been widely
explored. As a first stage towards the development of a solution to learn
on-line macro-actions, we propose an algorithm to identify useful macro-actions
based on data mining techniques. The integration in the planning search of
these learned macro-actions shows significant improvements over six classical
planning benchmarks.

The analysis of correlation energy of the simplest first approximation of a
variational method for the intrashell states of two-electron atoms is the
purpose of the present work. This method allows to divide energy of atom on
Coulomb and additional not - Coulomb correlation parts with very high accuracy.
Thus all the Coulomb interaction completely is taken into account in
calculation and not-Coulomb terms enter only in additional correlation energy.
The general formula for energy of additional correlation interaction is
obtained and the constant of this interaction is determined. The algorithm of
calculation of total energy of two-electron atoms is offered. The outcomes of
calculations for intra-shell states are adduced and compared to the
experimental data . The arguments for the capability of existence of the
analytical solution for a three-body problem in atomic physics are presented.
Some reasons about probable practical consequences are presented. Most
interesting of them is the discovery that under certain conditions additional
electron-electron attraction can exceed classical electron-electron repulsion.

The first time I watched this show it was OK. There were some funny moments and I laughed a couple of times but this show is getting worse and worse. Carly and Sam's web show is NOT the least bit funny. They play a stupid video from the internet, scream at the camera and make some very bad jokes. And then the laugh track goes off?! One problem with the show is that none of the main characters are funny. Carly is not funny. Miranda Cosgrove's acting is lackluster at best. Her acting in this show is nothing like her acting from Drake And Josh. Her friend Sam is very rude and crude and the show is written in a way that makes her look like some kind of hillbilly. I mean they make jokes about her mom driving a rusty old truck, her mom smashing an old TV with a bat, and then there's the jokes about Sam failing in school, getting detention all the time and running from cops. None of that is funny at all. Then there's Freddy who is a computer geek. He isn't too funny unless his Mom is treating him like a baby. The show's only somewhat funny full time character is Carly's brother Spencer. He makes some funny jokes and does some pretty funny things like pretending to drive a space ship while making spaceship noises, knocking over a girl scouts' cookie table for revenge as they did the same thing to him. His material is the only thing worth laughing at. Aside from the characters other things make the show bad too. Like the fact that a couple of kids doing a local web show from a Seattle apartment is a worldwide hit and got them a free trip to Tokyo? Another thing is that how can a 26 year old single guy with no real job can pay for a 2 level apartment in downtown Seattle and raise his 13 year old sister and pay for a room full of camera and sound equipment including a remote controlled projector and a green screen and an HD camera? This sounds like it was written by a 10 year old. The worst thing is that the show contains some pretty questionable content. There are a couple of times when Carly(remember a 13 year old girl) appears on her internet web show in a bikini top. WTF? Then I saw an episode where Freddy tells Carly and Sam that he "slept in JUST his socks the night before." I mean WTF? Then there's an episode where Carly's rival Nevel blackmails her by taking her website rights and agrees to give her the website back in exchange for a kiss. Creepy! And I just saw an episode where Carly meets a boy who just moved into their apartment building and he has some kind of back injury and he takes off his shirt and Carly stands there drooling over him. I can't believe Nick even lets them show that kind off stuff and I can't believe that this was created by the same guy responsible for Drake and Josh. This show is not appropriate for kids under the age of 12 and that's even questionable. iCarly is just another addition to the long list of awful Nick programming.

Only 2 of 4 still working after limited use
I would recommend a different brand. One of the 4 did not work upon delivery. I ignored it at the time since it was cheap to buy. But recently another chord stopped working after only 5 months of sporadic use. Next time, I will go with a different brand.

The effect of a magnetic field on the dipole echo amplitude in glasses (at
temperatures of about 10 mK) induced by the dipole-dipole interaction of
nuclear spins has been theoretically studied. It has been shown that a change
in the positions of nuclear spins as a result of tunneling and their
interaction with the external magnetic field E_H lead to a nonmonotonic
magnetic field dependence of the dipole echo amplitude. The approximation that
the nuclear dipole-dipole interaction energy E_d is much smaller than the
Zeeman energy E_H has been found to be valid in the experimentally important
cases. It has been shown that the dipole echo amplitude in this approximation
may be described by a simple universal analytic function independent of the
microscopic structure of the two-level systems. An excellent agreement of the
theory with the experimental data has been obtained without fitting parameters
(except for the unknown echo amplitude)

8 Simple Rules for Dating My Teenage Daughter had an auspicious start. The supremely-talented Tom Shadyac was involved in the project. This meant that the comedy would be nothing less of spectacular, and that's exactly what happened: the show remains one of the freshest, funniest, wittiest shows made in a very long time. Every line, facial expression, casting choice, scene, all wreaked of perfection. There was not one episode after which I thought, "Man that wasn't as good as the rest". Each one was a standout. Again, this is the kind of perfectionism that we've come to expect from Tom. For those who don't know, Tom Shadyac is the director of Ace Ventura (first movie), The Nutty Professor (first one) and Liar Liar. Quite a résumé. He's a producer here not a director, but his magic touch is felt in every episode.The family consists of:<br /><br />The Father: Paul Hennessy (John Ritter): nice, slightly neurotic, can be a pushover from time to time, works as a sports writer. John unfortunately passed away in 2003 leaving a fond memory and near-sure cancellation contemplations by the suits.<br /><br />The Mother: Cate (Katey Sagal): come on, who didn't fall in love with Katey when she played Peg on Married With Children? Al Bundy was our hero. We viewers gave him the respect and love he never had. But without Peg's nonchalant, parasitic, lazy lifestyle, Al would've probably been just another Chicago dad instead of the mess that Peg (life, actually) caused him to be. Katey was a MILF back then and still is: a brune now (instead of a redhead) and just as buxom as ever. Cate is the conservative mom and loving wife. I know it sounds boring, but comedically, she fits perfectly. <br /><br />The Ditzy Blonde Daughter: Bridget (played to perfection by Kaley Cuoco): almost never has an idiot been played so well. Aside of Gob on Arrested Development, Bridget may well be a shoe-in for any awards given to this archetype. Bridget is shallow, self-centered, not very bright and a tad slutty in his look. She plays the dumb blonde role better than absolutely anyone IMO. Perfection. One of the high-points of the show.<br /><br />The Overlooked Geeky Daughter: Kerry (Amy Davidson): a brune and a geek, she gets no love from life or circumstances. Feels overlooked, under-appreciated and neglected most of the time. She's Bridget's younger sister (in reality she's older than her) and the two's extremely opposite personalities and brains cause endless clashes, to much of our amusement.<br /><br />The Son: Rory (Martin Spanjers): was the second funniest character IMO before the passing of Ritter, then John passes, new characters come and Rory is not the wise-cracking verbal-trouble-maker that he used to: that went mostly to David Spade's character. <br /><br />Those characters were the main ones at the time of John Ritter. Unfortunately enough, the insanely hilarious Larry Miller (one of my favorites) did not get lots of screen time. He played Paul's co-worker/competitor. After an aortic dissection cost Ritter his life in 2003 (September 11th), the show was on hiatus for a while. No one thought it could come back, but it did later on, with a couple of new additions. This began the second phase of the show, and the new characters were:<br /><br />The strict, confident school principal: Ed (Adam Arkin): I saw Adam here and there on talk shows. This was the first time that I saw him do anything. Impressed, is the word I use. His performance was very impressive. Sad he wasn't brought in earlier. He also plays Cate's potential love interest after Paul passes. The gradual progress towards this point (which would've sounded crazy at the beginning) earns the creators lots of praise. It was done slowly, carefully and excellently, with constant respect paid to the Paul (Ritter).<br /><br />The Attitude Grandpa: Jim Egan (James Garner): a surprisingly welcome addition to the series, he was cannon fodder for endless 'old' jokes, mainly by...<br /><br />The 35-year-old unemployed wise-cracking half-brother of the mom: CJ (played to insanely funny heights by David Spade): I knew Spade was funny, I just didn't know he was THIS funny. Somehow, Spade's very familiar presence is sensed inside his character (as opposed to a separable character), which is understandable, since he's a comic and he's on a comedy show. This eerie feeling is kinda like seeing someone borrow lots of material from David Spade's appearances in movies, talk shows and functions (award shows, etc.) and delivering a superb impersonation of Spade's voice and comedy style, except, that it IS Spade. By that I mean you realize he's not trying to play someone else, or a whole new character: he's being the goofy, funny Spade we've come to know, and he takes this pleasantly humorous formula to the absolute top. Every line he uttered, every sarcasm he begot, all classics, literally. Spade was CRAZY-funny; so, SO funny.<br /><br />The show's humor and drama were both upped after the show was back, but audiences thought, "John passed, it ain't gonna be the same anymore". This is understandable, considering we are talking about a group of people (American viewers) who gave 'Yes Dear' a free ride but caused Andy Richter Controls the Universe to be cancelled in no time. As the show's quality increased, its ratings declined. Soon it was no more, sadly. <br /><br />And I saved the best for last: fans of Married With Children are in for a treat. And boy, what a treat it was. I still shiver just remembering it. It's a surprise so good that it would be crazy for me to spoil it, even if I legitimately do it under the "spoiler..." pretext. Suffice it to say that it's something you'll NEVER forget. I know I won't :-)

We consider mixed Monge-Amp\`ere products of quasiplurisubharmonic functions
with analytic singularities, and show that such products may be regularized as
explicit one parameter limits of mixed Monge-Amp\`ere products of smooth
functions, generalizing results of Andersson, B{\l}ocki and the last author in
the case of non-mixed Monge-Amp\`ere products. Connections to the theory of
residue currents, going back to Coleff-Herrera, Passare and others, play an
important role in the proof. As a consequence we get an approximation of Chern
and Segre currents of certain singular hermitian metrics on vector bundles by
smooth forms in the corresponding Chern and Segre classes.

Begetting children is not a requirement for a canon law marriage. Willingness is, but it is impotence, not sterility, that is the bar. The term cry to heaven for vengeance is sloganeering, not doctrine and it applies to pederasty, not consensual sodomy. Cry all you want, at some point natural law rears its head and says that gays were born that way due to epigenesis in the womb and that they have every right to sexual expression that any human has. Ratzinger's opinion on the made up natural order notwithstanding.

We revisit the standard representation of the (inverse) Radon transform which
is well-known in the mathematical literature. We extend this representation to
the case involving the parton distributions. We have found the new additional
contribution which is essentially related to the generalized
transverse-momentum dependent parton distribution and double-distribution
functions. We discuss the possible relationship of this term with the Sivers
function.

Still this terrorist killed few compared to Nevada. And why do you think it is only Nevada's problem? You don't think it could spread?
Fact is it appears he was radicalized after he entered the country. You should be asking why and what can be done to prevent others from becoming radicalized. I suspect the answer lies in probably cutting out the discrimination and hatred directed against them.

Deep Learning is a state-of-the-art technique to make inference on extensive
or complex data. As a black box model due to their multilayer nonlinear
structure, Deep Neural Networks are often criticized to be non-transparent and
their predictions not traceable by humans. Furthermore, the models learn from
artificial datasets, often with bias or contaminated discriminating content.
Through their increased distribution, decision-making algorithms can contribute
promoting prejudge and unfairness which is not easy to notice due to lack of
transparency. Hence, scientists developed several so-called explanators or
explainers which try to point out the connection between input and output to
represent in a simplified way the inner structure of machine learning black
boxes. In this survey we differ the mechanisms and properties of explaining
systems for Deep Neural Networks for Computer Vision tasks. We give a
comprehensive overview about taxonomy of related studies and compare several
survey papers that deal with explainability in general. We work out the
drawbacks and gaps and summarize further research ideas.

We present new U-band photometry of the magnetic Helium-strong star Sigma Ori
E, obtained over 2004-2009 using the SMARTS 0.9-m telescope at Cerro Tololo
Inter-American Observatory. When combined with historical measurements, these
data constrain the evolution of the star's 1.19 d rotation period over the past
three decades. We are able to rule out a constant period at the p_null = 0.05%
level, and instead find that the data are well described (p_null = 99.3%) by a
period increasing linearly at a rate of 77 ms per year. This corresponds to a
characteristic spin-down time of 1.34 Myr, in good agreement with theoretical
predictions based on magnetohydrodynamical simulations of angular momentum loss
from magnetic massive stars. We therefore conclude that the observations are
consistent with Sigma Ori E undergoing rotational braking due to its magnetized
line-driven wind.

We apply a method of Davenport to improve several estimates for slim
exceptional sets associated with the asymptotic formula in Waring's problem. In
particular, we show that the anticipated asymptotic formula in Waring's problem
for sums of seven cubes holds for all but $O(N^{1/3+\epsilon})$ of the natural
numbers not exceeding $N$.

Having lost most of their support in Canada, Conservatives are leaning on their friends south of the border. There is no depth some people won't stoop to in search of power.

We propose a new method to tackle the mapping challenge from time-series data
to spatial image in the field of seismic exploration, i.e., reconstructing the
velocity model directly from seismic data by deep neural networks (DNNs). The
conventional way of addressing this ill-posed inversion problem is through
iterative algorithms, which suffer from poor nonlinear mapping and strong
nonuniqueness. Other attempts may either import human intervention errors or
underuse seismic data. The challenge for DNNs mainly lies in the weak spatial
correspondence, the uncertain reflection-reception relationship between seismic
data and velocity model, as well as the time-varying property of seismic data.
To tackle these challenges, we propose end-to-end seismic inversion networks
(SeisInvNets) with novel components to make the best use of all seismic data.
Specifically, we start with every seismic trace and enhance it with its
neighborhood information, its observation setup, and the global context of its
corresponding seismic profile. From the enhanced seismic traces, the spatially
aligned feature maps can be learned and further concatenated to reconstruct a
velocity model. In general, we let every seismic trace contribute to the
reconstruction of the whole velocity model by finding spatial correspondence.
The proposed SeisInvNet consistently produces improvements over the baselines
and achieves promising performance on our synthesized and proposed SeisInv data
set according to various evaluation metrics. The inversion results are more
consistent with the target from the aspects of velocity values, subsurface
structures, and geological interfaces. Moreover, the mechanism and the
generalization of the proposed method are discussed and verified. Nevertheless,
the generalization of deep-learning-based inversion methods on real data is
still challenging and considering physics may be one potential solution.

We propose a GAN design which models multiple distributions effectively and
discovers their commonalities and particularities. Each data distribution is
modeled with a mixture of $K$ generator distributions. As the generators are
partially shared between the modeling of different true data distributions,
shared ones captures the commonality of the distributions, while non-shared
ones capture unique aspects of them. We show the effectiveness of our method on
various datasets (MNIST, Fashion MNIST, CIFAR-10, Omniglot, CelebA) with
compelling results.

Good evening Eric. Just so you know, and since you brought it up, my IQ has been measured in the above average range. I do not have a collage degree however. I am one of those people who grew up in the ghetto, I have spent a lifetime educating myself. I am also in the above average income bracket due to my own hard work. I read a verity of sources, I look beyond words and judge actions. I refuse to be used by the politically elitist. I will go beyond what you just said about the RNC and say it is our entire political system that has stopped doing the peoples business and instead preach hatred for everyone who dares to question them. I do find it despicable that HRC well be rewarded for her past corruption with votes from loyal dem. voters. Face it Eric, if there was even a hint of the amount of corruption around a repub. you, (and other dems.) would find no problem condemning them. Trump is a result of the dem. party, of the hate filled, insulting labels thrown at all who disagree.

Acoustic emission (AE) measurements performed during the compressive loading
of concrete samples with three different microstructures (aggregate sizes and
porosity) and four sample sizes revealed that failure is preceded by an
acceleration of the rate of fracturing events, power law distributions of AE
energies and durations near failure, and a divergence of the fracturing
correlation length and time towards failure. This argues for an interpretation
of compressive failure of disordered materials as a critical transition between
an intact and a failed state. The associated critical exponents were found to
be independent of sample size and microstructural disorder and close to
mean-field depinning values. Although compressive failure differs from
classical depinning in several respects, including the nature of the elastic
redistribution kernel, an analogy between the two processes allows deriving
(finite)-sizing effects on strength that match our extensive dataset. This
critical interpretation of failure may have also important consequences in
terms of natural hazards forecasting, such as volcanic eruptions, landslides,
or cliff collapses.

Quantum entanglement is an enigmatic and powerful property that has attracted
much attention due to its usefulness in new ways of communications, like
quantum teleportation and quantum key distribution. Much effort has been done
to quantify entanglement. Indeed, there exist some well-established
separability criterion and analytical formulas for the entanglement of
bipartite systems. In some of these, the crucial elements are the eigenvalues
of the partial transpose of the density matrix. In this paper, we show that one
can also have information about the entanglement of bipartite state, in C2xC2,
looking at the minimal principals of the partial transpose.

Penalization of the likelihood by Jeffreys' invariant prior, or by a positive
power thereof, is shown to produce finite-valued maximum penalized likelihood
estimates in a broad class of binomial generalized linear models. The class of
models includes logistic regression, where the Jeffreys-prior penalty is known
additionally to reduce the asymptotic bias of the maximum likelihood estimator;
and also models with other commonly used link functions such as probit and
log-log. Shrinkage towards equiprobability across observations, relative to the
maximum likelihood estimator, is established theoretically and is studied
through illustrative examples. Some implications of finiteness and shrinkage
for inference are discussed, particularly when inference is based on Wald-type
procedures. A widely applicable procedure is developed for computation of
maximum penalized likelihood estimates, by using repeated maximum likelihood
fits with iteratively adjusted binomial responses and totals. These theoretical
results and methods underpin the increasingly widespread use of reduced-bias
and similarly penalized binomial regression models in many applied fields.

The columnist pretends that the massive changes in Canada had NOTHING to do with government policies.
Wow.
I mean WOW.
Does he have a twin over in Japan or India, by chance? I mean, are there columnists in Japan and India saying to readers: "Oh, well, the reason in 2017 we have a citizenry that is 99 percent ethnic Japanese in Japan and following Japanese cultural traditions, well, that has NOTHING to do with government policies related to immigration and culture", and, oh, "well, the reason in 2017 we have a citizenry that is 99 percent ethnic Indian in India and following Indian cultural traditions, well, that has NOTHING to do with government policies related to immigration and culture".
I mean, it is every bit as RIDICULOUS to pretend that the Japanese and Indian populations are what they are in those countries for reasons that have NOTHING to do with government policy, as it is to ridiculously pretend that Canada's trajectory also has nothing to do with government policies.

Works great.
This is my second because my dog out grew the first. Well made. My dog has a real thin coat so needs a little help in the winter and she likes this vest and has not wiggled her way out of it. just wish it had reflective strips for at night. It has a plastic snap near the neck to help hold the vest in place while zipping, this snap is the hardest part to put it on her. To help keep hair from getting in zipper, hold finger ahead of zipper to help push hair out of the way.

This paper describes our approach in DSTC 8 Track 4: Schema-Guided Dialogue
State Tracking. The goal of this task is to predict the intents and slots in
each user turn to complete the dialogue state tracking (DST) based on the
information provided by the task's schema. Different from traditional
stage-wise DST, we propose an end-to-end DST system to avoid error accumulation
between the dialogue turns. The DST system consists of a machine reading
comprehension (MRC) model for non-categorical slots and a Wide & Deep model for
categorical slots. As far as we know, this is the first time that MRC and Wide
& Deep model are applied to DST problem in a fully end-to-end way. Experimental
results show that our framework achieves an excellent performance on the test
dataset including 50% zero-shot services with a joint goal accuracy of 0.8652
and a slot tagging F1-Score of 0.9835.

The ground-state Hartree-Fock (HF) wavefunction of the Hooke's atom is not
known in closed form, contrary to the exact solution. The single HF orbital
involved has thus far been studied using expansion techniques only, leading to
slightly disparate energies. Therefore, the present letter aims at proposing
alternative definitions of the HF wavefunction. First, the HF limit is
ascertained using a simple expansion, which makes it possible to formulate
explicit expressions of HF properties. The resulting energy, 2.038 438 871 8
Eh, is found stable at the tenth digit. Second and more instructive, an
analysis of the Hartree equation makes it possible to infer a remarkably simple
and accurate HF orbital, leading to an energy exceeding by 5.76 10-7 Eh only
the above HF limit. This orbital makes it possible to obtain (near)
Hartree-Fock properties in closed-form, which in turn enables handy comparisons
with exact quantities.

We give a lower bound for the numerical index of the real space $L_p(\mu)$
showing, in particular, that it is non-zero for $p\neq 2$. In other words, it
is shown that for every bounded linear operator $T$ on the real space
$L_p(\mu)$, one has $$ \sup{\Bigl|\int |x|^{p-1}\sign(x) T x d\mu \Bigr| : x\in
L_p(\mu), \|x\|=1} \geq \frac{M_p}{12\e}\|T\| $$ where
$M_p=\max_{t\in[0,1]}\frac{|t^{p-1}-t|}{1+t^p}>0$ for every $p\neq 2$. It is
also shown that for every bounded linear operator $T$ on the real space
$L_p(\mu)$, one has $$ \sup{\int |x|^{p-1}|Tx| d\mu : x\in L_p(\mu), \|x\|=1}
\geq \frac{1}{2\e}\|T\|. $$

Controlling a high degrees of freedom humanoid robot is acknowledged as one
of the hardest problems in Robotics. Due to the lack of mathematical models, an
approach frequently employed is to rely on human intuition to design keyframe
movements by hand, usually aided by graphical tools. In this paper, we propose
a learning framework based on neural networks in order to mimic humanoid robot
movements. The developed technique does not make any assumption about the
underlying implementation of the movement, therefore both keyframe and
model-based motions may be learned. The framework was applied in the RoboCup 3D
Soccer Simulation domain and promising results were obtained using the same
network architecture for several motions, even when copying motions from
another teams.

Sorry, convict--between you and I, only one of us is frantically filling up these pages with comments under a plethora of silly pseudonyms in a childish bid for attention. That would be you.
It appears you operate according to the concept that negative attention is preferable to none at all. Perhaps consider feeding your cats more if you're feeling lonely.

Updated Review
UPDATE - To be very fair to this seller, they refunded my purchase in full. The product I received may have been sub par, but their customer service was excellent, so please do not be put off from purchasing from them. Original Review First of all, they took nearly a month to arrive. When they did arrive, there was a small amount of damage to the plastic arms, just scuff marks and scrapes, but I thought, they are meant for outside, so I can live with that. However, on the very first usage, the chairs collapsed ripping out the securing mounts for the mechanism that keeps the chair legs in place. The build quality and the metal is of really poor quality, as is the design which puts all the stress on the weakest part of the chair. I cannot in all good conscience recommend them to anyone.

Approaching the 1.5329-dB shaping (granular) gain limit in mean-squared error
(MSE) quantization of R^n is important in a number of problems, notably
dirty-paper coding. For this purpose, we start with a binary low-density
generator-matrix (LDGM) code, and construct the quantization codebook by
periodically repeating its set of binary codewords, or them mapped to m-ary
ones with Gray mapping. The quantization algorithm is based on belief
propagation, and it uses a decimation procedure to do the guessing necessary
for convergence. Using the results of a true typical decimator (TTD) as
reference, it is shown that the asymptotic performance of the proposed
quantizer can be characterized by certain monotonicity conditions on the code's
fixed point properties, which can be analyzed with density evolution, and
degree distribution optimization can be carried out accordingly. When the
number of iterations is finite, the resulting loss is made amenable to analysis
through the introduction of a recovery algorithm from ``bad'' guesses, and the
results of such analysis enable further optimization of the pace of decimation
and the degree distribution. Simulation results show that the proposed
LDGM-based quantizer can achieve a shaping gain of 1.4906 dB, or 0.0423 dB from
the limit, and significantly outperforms trellis-coded quantization (TCQ) at a
similar computational complexity.

It is hard to stabilize the p-wave superfluid state of cold atomic gas in
free space due to inelastic collisional losses. We consider the p-wave Feshbach
resonance in an optical lattice, and show that it is possible to have a stable
p-wave superfluid state where the multi-atom collisional loss is suppressed
through the quantum Zeno effect. We derive the effective Hamiltonian for this
system, and calculate its phase diagram in a one-dimensional optical lattice.
The results show rich phase transitions between the p-wave superfluid state and
different types of insulator states induced either by interaction or by
dissipation.

I broke my own rule buying this movie from the $5.88 bin at Walmart. Basically, if a movie has a big star in it, and you've never heard of it before, it's usually for a reason. Well in the case of this movie, the reason is because it SUCKED! They plaster Sandra Bullock's photo and name all over the cover of the DVD as bait, and it reeled this little fishie right on in. I was thinking of donating the disc to charity, or giving it to the library, but I don't think I would want to subject anyone else in the world to this movie. Worst lines: "What do you mean army buddies?" "What do you mean your dad?"

In this work, we review two methods used to approach singular Hamiltonians in
(2+1) dimensions. Both methods are based on the self-adjoint extension
approach. It is very common to find singular Hamiltonians in quantum mechanics,
especially in quantum systems in the presence of topological defects, which are
usually modelled by point interactions. In general, it is possible to apply
some kind of regularization procedure, as the vanishing of the wave function at
the location of the singularity, ensuring that the wave function is
square-integrable and then can be associated with a physical state. However, a
study based on the self-adjoint extension approach can lead to more general
boundary conditions that still gives acceptable physical states. We exemplify
the methods by exploring the bound and scattering scenarios of a spin 1/2
charged particle with an anomalous magnetic moment in the Aharonov-Bohm
potential in the conical space.

Agreed, we are discussing issues prior to original sin. I am using Last Common Ancestor in the sense used by geneticists in developing trees of life. That perspective sees no discontinuity at any point in evolution, and most certainly does not entertain our specific religious problem of ensoulment, a necessary and irreducible discontinuity from our perspective.
In imagining, in speculating, about a solution, I accept direct creation by Yahweh in the sense of ensoulment as inescapable, but see no reason to imagine the direct creation of the bodies of our earliest ancestors (which you seem to see as required?). Indeed, Yahweh directly creates everyone of us in the womb by a similar act of direct creation, of ensoulment of sexually reproduced biological matter. I suggest that once one ponders the equivalence of that first ensoulment and all subsequent ensoulments, each an instance of direct creation, then the starting point disappears as a problem.

A Brownian Motor is a nanoscale or molecular device that combines the effects
of thermal noise, spatial or temporal asymmetry, and directionless input energy
to drive directed motion. Because of the input energy, Brownian motors function
away from thermodynamic equilibrium and concepts such as linear response
theory, fluctuation dissipation relations, and detailed balance do not apply.
The {\em generalized} fluctuation-dissipation relation, however, states that
even under strongly thermodynamically non-equilibrium conditions the ratio of
the probability of a transition to the probability of the time-reverse of that
transition is the exponent of the change in the internal energy of the system
due to the transition. Here, we derive an extension of the generalized
fluctuation dissipation theorem for a Brownian motor for the ratio between the
probability for the motor to take a forward step and the probability to take a
backward step.

Smart home devices are vulnerable to passive inference attacks based on
network traffic, even in the presence of encryption. In this paper, we present
PINGPONG, a tool that can automatically extract packet-level signatures for
device events (e.g., light bulb turning ON/OFF) from network traffic. We
evaluated PINGPONG on popular smart home devices ranging from smart plugs and
thermostats to cameras, voice-activated devices, and smart TVs. We were able
to: (1) automatically extract previously unknown signatures that consist of
simple sequences of packet lengths and directions; (2) use those signatures to
detect the devices or specific events with an average recall of more than 97%;
(3) show that the signatures are unique among hundreds of millions of packets
of real world network traffic; (4) show that our methodology is also applicable
to publicly available datasets; and (5) demonstrate its robustness in different
settings: events triggered by local and remote smartphones, as well as by
homeautomation systems.

Following two dictums roadmap of Einstein (one, for incorporation of maximum
of empirical facts, and the other, on long continued experimental verifications
for perfecting a scientific theory) for future generations to make his General
Relativity Theory (GRT) evolve to perfection, it is necessary to experimentally
confirm his concept on General relativistic nature of speed of light, c, which
relates to the variation of c under the influence of gravitational field, and
whose experimental confirmation is long overdue.
This paper gives the Execution and some Additional Details for the Space
Experiment Proposed for GRT, so that any of the Space research organizations
(viz., NASA, ESA, ASI, ISRO, etc.) would conduct this low cost experiment,
during Space missions to Mercury, Venus, or the sun, or may choose to conduct
it as an independent space mission as the cost may be brought down by sending
micro satellites using the launch sharing facility of any other lending
country. Even an advanced country may conduct this experiment at low cost by
sending a micro satellite (called a co-passenger satellite) by arranging with
the Space research organization of any lending country, which is sending a
primary satellite for a space mission to any of the desired locations.
At present, even a small country interested in making a historic contribution
for making GRT of Einstein evolve, but not having a Space research
organization, may contract with an experienced organization, or hire the
services of an experienced project director who
* can organize the planning, procurement, and launching of a micro satellite
carrying the laser device, from launch pad of another country (adopting the
piggy back launching method), and
* can guide (else, can hire the services of a Principal Investigator, from
some renowned institute) remote operation of the laser device for a few days.

Not sure how they can claim fade resistant
I bought the red and did a lot of research to find one with good reviews and fade resistant. I’ve had mine up for only 2 months and it is horribly faded and we haven’t even had our summer yet. Really disappointed in that otherwise seems to be a good quality umbrella.

This work considers the way that quantum loop effects modify the propagation
of light in curved space. The calculation of the refractive index for scalar
QED is reviewed and then extended for the first time to QED with spinor
particles in the loop. It is shown how, in both cases, the low frequency phase
velocity can be greater than c, as found originally by Drummond and Hathrell,
but causality is respected in the sense that retarded Green functions vanish
outside the lightcone. A "phenomenology" of the refractive index is then
presented for black holes, FRW universes and gravitational waves. In some
cases, some of the polarization states propagate with a refractive index having
a negative imaginary part indicating a potential breakdown of the optical
theorem in curved space and possible instabilities.

Le $X$ be a $C^\infty$-manifold and $\g$ be a finite dimensional Lie algebra
acting freely on $X$. Let $r \in \ve^2(\g)$ be such that $Z=[r,r] \in
\ve^3(\g)^\g$. In this paper we prove that every quasi-Poisson
$(\g,Z)$-manifold can be quantized. This is a generalization of the existence
of a twist quantization of coboundary Lie bialgebras (\cite{EH}) in the case
$X=G$ (where $G$ is the simply connected Lie group corresponding to $\g$). We
deduce our result from a generalized formality theorem. In the case Z=0, we get
a new proof of the existence of (equivariant) formality theorem and so
(equivariant) quantization of Poisson manifold ({\it cf.} \cite{Ko,Do}). As a
consequence of our results, we get quantization of modified classical dynamical
$r$-matrices over abelian bases in the reductive case

Let $T:A\to X$ be a bounded linear operator, where $A$ is a C$^*$-algebra,
and $X$ denotes an essential Banach $A$-bimodule. We prove that the following
statements are equivalent:
$(a)$ $T$ is anti-derivable at zero (i.e. $ab =0$ in $A$ implies $T(b) a + b
T(a)=0$);
$(b)$ There exist an anti-derivation $d:A\to X^{**}$ and an element $\xi \in
X^{**}$ satisfying $\xi a = a \xi,$ $\xi [a,b]=0,$ $T(a b) = b T(a) + T(b) a -
b \xi a,$ and $T(a) = d(a) + \xi a,$ for all $a,b\in A$.
We also prove a similar equivalence when $X$ is replaced with $A^{**}$. This
provides a complete characterization of those bounded linear maps from $A$ into
$X$ or into $A^{**}$ which are anti-derivable at zero. We also present a
complete characterization of those continuous linear operators which are
$^*$-anti-derivable at zero.

An almost disjoint family $\mathcal A$ of subsets of $\mathbb N$ is said to
be $\mathbb R$-embeddable if there is a function $f:\mathbb N\rightarrow
\mathbb R$ such that the sets $f[A]$ are ranges of real sequences converging to
distinct reals for distinct $A\in \mathcal A$. It is well known that almost
disjoint families which have few separations, such as Luzin families, are not
$\mathbb R$-embeddable. We study extraction principles related to $\mathbb
R$-embeddability and separation properties of almost disjoint families of
$\mathbb N$ as well as their limitations. An extraction principle whose
consistency is our main result is: every almost disjoint family of size
continuum contains an $\mathbb R$-embeddable subfamily of size continuum. It is
true in the Sacks model. The Cohen model serves to show that the above
principle does not follow from the fact that every almost disjoint family of
size continuum has two separated subfamilies of size continuum. We also
construct in ZFC an almost disjoint family, where no two uncountable
subfamilies can be separated but always a countable subfamily can be separated
from any disjoint subfamily.
Using a refinement of the $\mathbb R$-embeddability property called a
controlled $\mathbb R$-embedding property we obtain the following results
concerning Akemann-Doner C*-algebras which are induced by uncountable almost
disjoint families: a) In ZFC there are Akemann-Doner C*-algebras of density
$\mathfrak c$ with no commutative subalgebras of density $\mathfrak c$, b) It
is independent from ZFC whether there is an Akemann-Doner algebra of density
$\mathfrak c$ with no nonseparable commutative subalgebra. This completes an
earlier result that there is in ZFC an Akemann-Doner algebra of density
$\omega_1$ with no nonseparable commutative subalgebra.
