We report the observation of imaging beyond the diffraction limit due to
bound surface states in negative refraction photonic crystals. We achieve an
effective negative index figure-of-merit [-Re(n)/Im(n)] of at least 380, ~125x
improvement over recent efforts in the near-infrared, with a 0.4 THz bandwidth.
Supported by numerical and theoretical analyses, the observed near-field
resolution is 0.47 lambda, clearly smaller than the diffraction limit of 0.61
lambda. Importantly, we show this sub-diffraction imaging is due to the
resonant excitation of surface slab modes, allowing refocusing of
non-propagating evanescent waves.

Exactly what I was looking for
I bought this because it had a 5-star rating on every link that had this product. I was really hoping that a product this inexpensive worked as well as I thought it would. This sealer is amazing! It works just as well as my $200 sealer that I had for 15 years. I was absolutely not disappointed! Worth every penny! Thank you to everyone who wrote a review! You helped me make up my mind.

This movie is a remake of two movies that were a lot better. The last one, Heaven Can Wait, was great, I suggest you see that one. This one is not so great. The last third of the movie is not so bad and Chris Rock starts to show some of the comic fun that got him to where he is today. However, I don't know what happened to the first two parts of this movie. It plays like some really bad "B" movie where people sound like they are in some bad TV sit-com. The situations are forced and it is like they are just trying to get the story over so they can start the real movie. It all seems real fake and the editing is just bad. I don't know how they could release this movie like that. Anyway, the last part isn't to bad, so wait for the video and see it then.

In this paper we study the equilibrium energy fluctuation field of a
one-dimensional reversible non gradient model. We prove that the limit
fluctuation process is governed by a generalized Ornstein- Uhlenbeck process,
which covariances are given in terms of the diffusion coefficient. Adapting the
non gradient method introduced by Varadhan, we are able to derive the diffusion
coefficient. The fact that the conserved quantity (energy) is not a linear
functional of the coordinates of the system, introduces new difficulties of
geometric nature when applying the nongradient method.

The shape gradient is a local sensitivity function that provides the change
in a figure of merit associated with a perturbation to the shape of the object.
The shape gradient can be used for gradient-based optimization, sensitivity
analysis, and tolerance calculations. However, it is generally expensive to
compute from finite-difference derivatives for shapes which are described by
many parameters, as is the case for stellarator geometry. In an accompanying
work (Antonsen et al. 2019), generalized self-adjointness relations are
obtained for MHD equilibria. These describe the relation between perturbed
equilibria due to changes in the rotational transform or toroidal current
profiles, displacements of the plasma boundary, modifications of currents in
the vacuum region, or the addition of bulk forces. These are applied to
efficiently compute the shape gradient of functions of magnetohydrodynamic
(MHD) equilibria with an adjoint approach. In this way, the shape derivative
with respect to any perturbation applied to the plasma boundary or coil shapes
can be computed with only one additional MHD equilibrium solution. We
demonstrate that this approach is applicable for several figures of merit of
interest for stellarator configuration optimization: the magnetic well, the
magnetic ripple on axis, the departure from quasisymmetry, the effective ripple
in the low-collisionality $1/\nu$ regime ($\epsilon_{\text{eff}}^{3/2})$ (Nemov
et al. 1999), and several finite collisionality neoclassical quantities.
Numerical verification is demonstrated for the magnetic well figure of merit
with the VMEC code (Hirshman & Whitson 1983) and for the magnetic ripple with
modification of the ANIMEC code (Cooper et al. 1992). Comparisons with the
direct approach demonstrate that to obtain agreement within several percent,
the adjoint approach provides a factor of $\mathcal{O}(10^3)$ in computational
savings.

We study Stanley's long-standing conjecture that the h-vectors of matroid
simplicial complexes are pure O-sequences. Our method consists of a new and
more abstract approach, which shifts the focus from working on constructing
suitable artinian level monomial ideals, as often done in the past, to the
study of properties of pure O-sequences. We propose a conjecture on pure
O-sequences and settle it in small socle degrees. This allows us to prove
Stanley's conjecture for all matroids of rank 3. At the end of the paper, using
our method, we discuss a first possible approach to Stanley's conjecture in
full generality. Our technical work on pure O-sequences also uses very recent
results of the third author and collaborators.

(Abridged) The formation of massive spheroidal galaxies is studied on a
visually classified sample of 910 galaxies extracted from the ACS/HST images of
the GOODS North and South fields (0.4<z<.5). Three key observables are
considered: comoving number density, internal colour distribution; and the
Kormendy relation. The comoving number density of the most massive galaxies is
found not to change significantly with redshift. One quarter of the whole
sample of early-types are photometrically classified as blue galaxies. On a
volume-limited subset out to z<0.7, the average stellar mass of the blue
ellipticals is 5E9Msun compared to 4E10Msun for red ellipticals. On a
volume-limited subsample of bright galaxies (Mv<-21) out to z=1.4 we find only
4% are blue early-types, in contrast with 26% for the full sample. The
intrinsic colour distribution correlates overall bluer colours with **blue
cores** (positive radial gradients of colour), suggesting an inside-out process
of formation. The redshift evolution of the observed colour gradients is
incompatible with a significant variaton in stellar age within each galaxy. The
slope of the Kormendy relation in the subsample of massive galaxies does not
change between z=0 and z=1.4.

In this work we study interacting electrons on square lattice in the presence
of strong Rashba spin-orbit interaction. The spin-orbit term forces the
time-reversal electron states to be paired in even Cooper channels. For
concreteness, we only consider the repulsive onsite Hubbard and
nearest-neighbor coulomb interactions, the so called extended Hubbard model. To
examine the superconducting instability we obtain the effective interaction
between electrons within the random phase approximation and treat the pairing
instabilities driven by charge and spin fluctuations and their combined
effects. We mapped out the phase diagram of the model in terms of interactions
and electron fillings, and found that while the $d_{xy}$ and $d_{x^2-y^2}$
symmetries are the most likely pairing symmetries driven by charge and spin
fluctuations, respectively, the strong effect of both fluctuations yields
higher angular momentum Cooper instability. The possibility of topological
superconductivity and triplet pairing is also discussed.

This paper studies how to verify the conformity of a program with its
specification and proposes a novel constraint-programming framework for bounded
program verification (CPBPV). The CPBPV framework uses constraint stores to
represent the specification and the program and explores execution paths
nondeterministically. The input program is partially correct if each constraint
store so produced implies the post-condition. CPBPV does not explore spurious
execution paths as it incrementally prunes execution paths early by detecting
that the constraint store is not consistent. CPBPV uses the rich language of
constraint programming to express the constraint store. Finally, CPBPV is
parametrized with a list of solvers which are tried in sequence, starting with
the least expensive and less general. Experimental results often produce orders
of magnitude improvements over earlier approaches, running times being often
independent of the variable domains. Moreover, CPBPV was able to detect subtle
errors in some programs while other frameworks based on model checking have
failed.

Using tropical geometry we propose a mirror construction for monomial
degenerations of Calabi-Yau varieties in toric Fano varieties. The construction
reproduces the mirror constructions by Batyrev for Calabi-Yau hypersurfaces and
by Batyrev and Borisov for Calabi-Yau complete intersections. We apply the
construction to Pfaffian examples and recover the mirror given by Rodland for
the degree 14 Calabi-Yau threefold in PP^6 defined by the Pfaffians of a
general linear 7x7 skew-symmetric matrix.
We provide the necessary background knowledge entering into the tropical
mirror construction such as toric geometry, Groebner bases, tropical geometry,
Hilbert schemes and deformations. The tropical approach yields an algorithm
which we illustrate in a series of explicit examples.

We give an explicit formula for all tree amplitudes in N=4 SYM, derived by
solving the recently presented supersymmetric tree-level recursion relations.
The result is given in a compact, manifestly supersymmetric form and we show
how to extract from it all possible component amplitudes for an arbitrary
number of external particles and any arrangement of external particles and
helicities. We focus particularly on extracting gluon amplitudes which are
valid for any gauge theory. The formula for all tree-level amplitudes is given
in terms of nested sums of dual superconformal invariants and it therefore
manifestly respects both conventional and dual superconformal symmetry.

Variational autoencoders (VAEs), as well as other generative models, have
been shown to be efficient and accurate for capturing the latent structure of
vast amounts of complex high-dimensional data. However, existing VAEs can still
not directly handle data that are heterogenous (mixed continuous and discrete)
or incomplete (with missing data at random), which is indeed common in
real-world applications. In this paper, we propose a general framework to
design VAEs suitable for fitting incomplete heterogenous data. The proposed
HI-VAE includes likelihood models for real-valued, positive real valued,
interval, categorical, ordinal and count data, and allows accurate estimation
(and potentially imputation) of missing data. Furthermore, HI-VAE presents
competitive predictive performance in supervised tasks, outperforming
supervised models when trained on incomplete data.

We study the effects of T-odd interactions of top-quark via the pair
production of top-quark in the semileptonic detection modes at the Large Hadron
Collider by means of the T-odd observables constructed through the momenta of
the observed decay products of the top (and anti-top)-quark for a wide range of
CP-violating scale $\Lambda$. Estimates on the sensitivities of the coupling
strength of such interactions for 13 TeV LHC energy with $\int \mathcal L dt$ =
36.1 fb$^{-1}$, 140 fb$^{-1}$ and for HL-LHC with 14 TeV energy with integrated
luminosities of 0.3 ab$^{-1}$, 1 ab$^{-1}$, 2 ab$^{-1}$ and 3 ab$^{-1}$ are
also presented for $\Lambda$ ranging between $M_W$ and 2 TeV.

This is pretty ridiculous. You have the option to refuse care and die the slow and painful way, at much more public expense. My Kidney docs discuss the conservative care at least once a year. Translation, you can refuse dialysis and they will try to make you as comfortable as possible until you die from toxic levels of potassium, sodium, phosphate, urea ... and from fluid bloat.
When docs were trying convincing me to go along with 24x7 IVs in both arms, double digit multiple transfusions and exotic injection antibiotics to deal with the bacterial infection on my first dialysis perm catheter one tried the "what about spirituality and religion". I laughed at her, but perhaps she was serious, not just checking off an item on the list. Some docs may have personal reservations about AD.
People think of military, police, firefighting, prison guards as high stress occupations. Front line ambulance, ER, and other health care workers see people dying, maimed, and diseased more often.

When an experimentalist measures a time series of qubits, the outcomes
generate a classical stochastic process. We show that measurement induces high
complexity in these processes in two specific senses: they are inherently
unpredictable (positive Shannon entropy rate) and they require an infinite
number of features for optimal prediction (divergent statistical complexity).
We identify nonunifilarity as the mechanism underlying the resulting
complexities and examine the influence that measurement choice has on the
randomness and structure of measured qubit processes. We introduce new
quantitative measures of this complexity and provide efficient algorithms for
their estimation.

We give formulae for the cumulants of complex Wishart (LUE) and inverse
Wishart matrices (inverse LUE). Their large-$N$ expansions are generating
functions of double (strictly and weakly) monotone Hurwitz numbers which count
constrained factorisations in the symmetric group. The two expansions can be
compared and combined with a duality relation proved in [F. D. Cunden, F.
Mezzadri, N. O'Connell and N. J. Simm, arXiv:1805.08760] to obtain: i) a
combinatorial proof of the reflection formula between moments of LUE and
inverse LUE at genus zero and, ii) a new functional relation between the
generating functions of monotone and strictly monotone Hurwitz numbers. The
main result resolves the integrality conjecture formulated in [F. D. Cunden, F.
Mezzadri, N. J. Simm and P. Vivo, J. Phys. A 49 (2016)] on the time-delay
cumulants in quantum chaotic transport. The precise combinatorial description
of the cumulants given here may cast new light on the concordance between
random matrix and semiclassical theories.

Neural machine translation (NMT) models are usually trained with the
word-level loss using the teacher forcing algorithm, which not only evaluates
the translation improperly but also suffers from exposure bias. Sequence-level
training under the reinforcement framework can mitigate the problems of the
word-level loss, but its performance is unstable due to the high variance of
the gradient estimation. On these grounds, we present a method with a
differentiable sequence-level training objective based on probabilistic n-gram
matching which can avoid the reinforcement framework. In addition, this method
performs greedy search in the training which uses the predicted words as
context just as at inference to alleviate the problem of exposure bias.
Experiment results on the NIST Chinese-to-English translation tasks show that
our method significantly outperforms the reinforcement-based algorithms and
achieves an improvement of 1.5 BLEU points on average over a strong baseline
system.

Markov chain Monte Carlo (MCMC) sampling of posterior distributions arising
in Bayesian inverse problems is challenging when evaluations of the forward
model are computationally expensive. Replacing the forward model with a
low-cost, low-fidelity model often significantly reduces computational cost;
however, employing a low-fidelity model alone means that the stationary
distribution of the MCMC chain is the posterior distribution corresponding to
the low-fidelity model, rather than the original posterior distribution
corresponding to the high-fidelity model. We propose a multifidelity approach
that combines, rather than replaces, the high-fidelity model with a
low-fidelity model. First, the low-fidelity model is used to construct a
transport map that deterministically couples a reference Gaussian distribution
with an approximation of the low-fidelity posterior. Then, the high-fidelity
posterior distribution is explored using a non-Gaussian proposal distribution
derived from the transport map. This multifidelity "preconditioned" MCMC
approach seeks efficient sampling via a proposal that is explicitly tailored to
the posterior at hand and that is constructed efficiently with the low-fidelity
model. By relying on the low-fidelity model only to construct the proposal
distribution, our approach guarantees that the stationary distribution of the
MCMC chain is the high-fidelity posterior. In our numerical examples, our
multifidelity approach achieves significant speedups compared to
single-fidelity MCMC sampling methods.

We perform a multivariate analysis of Higgs-pair production in $HH \to b\bar
b \gamma\gamma$ channel at the HL-LHC to probe the trilinear Higgs
self--coupling $\lambda_{3H}$, which takes the value of 1 in the SM. We
consider all the known background processes. Also, for the signal we are the
first to adopt the most recent event generator of POWHEG-BOX-V2 to exploit the
NLO distributions for Toolkit for Multivariate Data Analysis (TMVA), taking
account of the full top--quark mass dependence. Through Boosted Decision Tree
(BDT) analysis trained for $\lambda_{3H}=1$, we find that the significance can
reach up to 1.95 with about $9$ signal and $18$ background events. In addition,
the Higgs boson self-coupling can be constrained to $1.00 < \lambda_{3H} <
6.22$ at 95\% confidence level (CL). We also perform a likelihood fitting of
$M_{\gamma\gamma bb}$ distribution and find the $1\sigma$ confidence interval
(CI) of $0.1 < \lambda_{3H} < 2.2\, \cup\,5.4 < \lambda_{3H} < 6.6$ for the
$\lambda_{3H}=1$ nominal set. On the other hand, using BDTs trained for each
value of $\lambda_{3H}$, we find a bulk region of $0.5 <\sim \lambda_{3H}
<\sim~ 4.5$, for which it is hard to pin down the trilinear coupling.

Two words to back up what Representative Wilson states and to really show this is an epidemic of legal kidnapping without the State following federal Laws but gladly accept federal funding to kidnap & place ASRC shareholders with nonshareholders: Anaktuvuk Pass. Judges, OCS workers, Guardian Ad Litems, Public Defenders, even the States Custody Investigators office joke that there are no more children in Anaktuvuk Pass because of OCS's legal kidnapping. I screamed at Danielle Butler as a kidnapper while she had her newborn kid in her office with her...plus her full-in closed 4-6 of her caseload while she was on maternity leave. People who are in denial about this should go through & experience how OCS operates first hand. Stupid sheep....

The Shapley Concentration ($z\approx0.048$) covers several degrees in the
Southern Hemisphere, and includes galaxy clusters in advanced evolutionary
stage, groups of clusters in the early stages of merger, fairly massive
clusters with ongoing accretion activity, and smaller groups located in
filaments in the regions between the main clusters. With the goal to
investigate the role of cluster mergers and accretion on the radio galaxy
population, we performed a multi-wavelength study of the BCGs and of the
galaxies showing extended radio emission in the cluster complexes of Abell 3528
and Abell 3558. Our study is based on a sample of 12 galaxies. We observed the
clusters with the GMRT at 235, 325 and 610 MHz, and with the VLA at 8.46 GHz.
We complemented our study with the TGSS at 150 MHz, the SUMSS at 843 MHz and
ATCA at 1380, 1400, 2380, and 4790 MHz data. Optical imaging with ESO-VST and
mid-IR coverage with WISE are also available for the host galaxies. We found
deep differences in the properties of the radio emission of the BCGs in the two
cluster complexes. The BCGs in the A3528 complex and in A3556, which are
relaxed cool-core objects, are powerful active radio galaxies. They also
present hints of restarted activity. On the contrary, the BCGs in A3558 and
A3562, which are well known merging systems, are very faint, or quiet, in the
radio band. The optical and IR properties of the galaxies are fairly similar in
the two complexes, showing all passive red galaxies. Our study shows remarkable
differences in the radio properties of the BGCs, which we relate to the
different dynamical state of the host cluster. On the contrary, the lack of
changes between such different environments in the optical band suggests that
the dynamical state of galaxy clusters does not affect the optical counterparts
of the radio galaxies, at least over the life-time of the radio emission.

We study the phase diagram of quark matter and nuclear properties based on
the strong coupling expansion of lattice QCD. Both of baryon and finite
coupling correction are found to have effects to extend the hadron phase to a
larger mu direction relative to Tc. In a chiral RMF model with logarithmic
sigma potential derived in the strong coupling limit of lattice QCD, we can
avoid the chiral collapse and normal and hypernuclei properties are well
described.

We study the basic quantum mechanics for a fully general set of Dirac
matrices in a curved spacetime by extending Pauli's method. We further extend
this study to three versions of the Dirac equation: the standard
(Dirac-Fock-Weyl or DFW) equation, and two alternative versions, both of which
are based on the recently proposed linear tensor representations of the Dirac
field (TRD). We begin with the current conservation: we show that the latter
applies to any solution of the Dirac equation, iff the field of Dirac matrices
$\gamma ^\mu $ satisfies a specific PDE. This equation is always satisfied for
DFW with its restricted choice for the $\gamma ^\mu $ matrices. It similarly
restricts the choice of the $\gamma ^\mu $ matrices for TRD. However, this
restriction can be achieved. The frame dependence of a general Hamiltonian
operator is studied. We show that in any given reference frame with minor
restrictions on the spacetime metric, the axioms of quantum mechanics impose a
unique form for the Hilbert space scalar product. Finally, the condition for
the general Dirac Hamiltonian operator to be Hermitian is derived in a general
curved spacetime. For DFW, the validity of this hermiticity condition depends
on the choice of the $\gamma ^\mu $ matrices.

We introduce the notion of balanced pair of additive subcategories in an
abelian category. We give sufficient conditions under which the balanced pair
of subcategories gives rise to equivalent homotopy categories of complexes. As
an application, we prove that for a left-Gorenstein ring, there exists a
triangle-equivalence between the homotopy category of its Gorenstein projective
modules and the homotopy category of its Gorenstein injective modules, which
restricts to a triangle-equivalence between the homotopy category of projective
modules and the homotopy category of injective modules. In the case of
commutative Gorenstein rings we prove that up to a natural isomorphism our
equivalence extends Iyengar-Krause's equivalence.

Globular cluster ages provide both an important test of models of globular
cluster formation and a powerful method to constrain the assembly history of
galaxies. Unfortunately, measuring the ages of unresolved old stellar
populations has proven challenging. Here, we present a novel technique that
combines optical photometry with metallicity constraints from near-infrared
spectroscopy in order to measure ages. After testing the method on globular
clusters in the Milky Way and its satellite galaxies, we apply our technique to
three massive early-type galaxies using data from the SLUGGS Survey. The three
SLUGGS galaxies and the Milky Way show dramatically different globular cluster
age and metallicity distributions, with NGC 1407 and the Milky Way showing
mostly old globular clusters while NGC 3115 and NGC 3377 show a range of
globular ages. This diversity implies different galaxy formation histories and
that the globular cluster optical colour-metallicity relation is not universal
as is commonly assumed in globular cluster studies. We find a correlation
between the median age of the metal rich globular cluster populations and the
age of the field star populations, in line with models where globular cluster
formation is a natural outcome of high intensity star formation.

$K\rightarrow \pi\nu \bar\nu$ is one of the theoretically cleanest meson
decay where to look for indirect effects of new physics complementary to LHC
searches. The NA62 experiment at CERN SPS is designed to measure the branching
ratio of the $K^+\rightarrow \pi^+\nu \bar\nu$ decay with 10\% precision. After
commissioning, in 2016 first data set good for physics has been collected. The
data taking is foreseen till the LS2 at the end of 2018. The analysis method
has been tested with 5\% of the full 2016 statistics. Results obtained with
this subsample will be shown. The status of the experiment will be reviewed,
and prospects will be presented, together with a mention to the broader NA62
physics program.

The poms - well OK, mainly the toffs and so-called aristocrats - still haven't worked out that they screwed my birth country back in 1914 when they went into a hopeless war started by one of Brenda's, sorry, the 'Queen's', relatives, Kaiser Wilhelm. They still haven't worked out there is no more Empire (even though they give out MBEs and OBEs with 'For God and Empire' on them!) and think they can just tell the Johnny Foreigners where to go. It'd be quite funny, actually, if it wasn't so stupid.

The results of the spectral, energetical and temporal characteristics of
radiation in the presence of the photonic flame effect are presented.
Artificial opal posed on Cu plate at the temperature of liquid nitrogen boiling
point (77 K) being irradiated by nanosecond ruby laser pulse produces long-
term luminiscence with a duration till ten seconds with a finely structured
spectrum in the the antistocks part of the spectrum. Analogous visible
luminescence manifesting time delay appeared in other samples of the artificial
opals posed on the same plate. In the case of the opal infiltrated with
different nonlinear liquids the threshold of the luminiscence is reduced and
the spatial disribution of the bright emmiting area on the opal surface is
being changed. In the case of the putting the frozen nonlinear liquids on the
Cu plate long-term blue bright luminiscence took place in the frozen species of
the liquids. Temporal characteristics of this luminiscence are nearly the same
as in opal matrixes.

Outage probabilities in wireless networks depend on various factors: the node
distribution, the MAC scheme, and the models for path loss, fading and
transmission success. In prior work on outage characterization for networks
with randomly placed nodes, most of the emphasis was put on networks whose
nodes are Poisson distributed and where ALOHA is used as the MAC protocol. In
this paper we provide a general framework for the analysis of outage
probabilities in the high-reliability regime. The outage probability
characterization is based on two parameters: the intrinsic spatial contention
$\gamma$ of the network, introduced in [1], and the coordination level achieved
by the MAC as measured by the interference scaling exponent $\kappa$ introduced
in this paper. We study outage probabilities under the signal-to-interference
ratio (SIR) model, Rayleigh fading, and power-law path loss, and explain how
the two parameters depend on the network model. The main result is that the
outage probability approaches $\gamma\eta^{\kappa}$ as the density of
interferers $\eta$ goes to zero, and that $\kappa$ assumes values in the range
$1\leq \kappa\leq \alpha/2$ for all practical MAC protocols, where $\alpha$ is
the path loss exponent. This asymptotic expression is valid for all
motion-invariant point processes. We suggest a novel and complete taxonomy of
MAC protocols based mainly on the value of $\kappa$. Finally, our findings
suggest a conjecture that tightly bounds the outage probability for all
interferer densities.

The Medium Earth Orbit (MEO) region hosts satellites for navigation,
communication, and geodetic/space environmental science, among which are the
Global Navigation Satellites Systems (GNSS). Safe and efficient removal of
debris from MEO is problematic due to the high cost for maneuvers needed to
directly reach the Earth (reentry orbits) and the relatively crowded GNSS
neighborhood (graveyard orbits). Recent studies have highlighted the
complicated secular dynamics in the MEO region, but also the possibility of
exploiting these dynamics, for designing removal strategies. In this paper, we
present our numerical exploration of the long-term dynamics in MEO, performed
with the purpose of unveiling the set of reentry and graveyard solutions that
could be reached with maneuvers of reasonable DV cost. We simulated the
dynamics over 120-200 years for an extended grid of millions of fictitious MEO
satellites that covered all inclinations from 0 to 90deg, using non-averaged
equations of motion and a suitable dynamical model that accounted for the
principal geopotential terms, 3rd-body perturbations and solar radiation
pressure (SRP). We found a sizeable set of usable solutions with reentry times
that exceed ~40years, mainly around three specific inclination values: 46deg,
56deg, and 68deg; a result compatible with our understanding of MEO secular
dynamics. For DV <= 300 m/s (i.e., achieved if you start from a typical GNSS
orbit and target a disposal orbit with e<0.3), reentry times from GNSS
altitudes exceed ~70 years, while low-cost (DV ~= 5-35 m/s) graveyard orbits,
stable for at lest 200 years, are found for eccentricities up to e~0.018. This
investigation was carried out in the framework of the EC-funded "ReDSHIFT"
project.

We study the sets of the infinite sentences constructible with a dictionary
over a finite alphabet, from the viewpoint of descriptive set theory. Among
other things, this gives some true co-analytic sets. The case where the
dictionary is finite is studied and gives a natural example of a set at the
level omega of the Wadge hierarchy.

We consider a classical source, moving on the 4-D boundary of a 5-D ADS
space, that is coupled to quantum fields residing in the bulk.
Bremsstrahlung-like radiation of the corresponding quanta is shown to occur and
the S-matrix is derived assuming that the source is sufficiently massive so
that recoil effects are negligible. As an illustrative example, using the ADS
hard-wall model, we consider vector mesons coupled to a heavy nucleus that is
moved around at high speed in an accelerator ring. The meson radiation rate is
found to be finite but small. Much higher accelerations, such as when a pair of
heavy ions suffer an ultra peripheral collision, cause substantial emission of
various excited vector mesons. Predictions are made for the spectrum of this
radiation. A comparison is made against existing photon-pomeron fusion
calculations for the transverse momentum spectra of rho mesons. These have the
same overall shape as the recently measured transverse momentum distributions
at RHIC.

This work is concerned with different aspects of spectrahedra and their
projections, sets that are important in semidefinite optimization. We prove
results on the limitations of so called Lasserre and theta body relaxation
methods for semialgebraic sets and varieties. As a special case we obtain the
main result of the paper "Exposed faces of semidefinite representable sets" of
Netzer, Plaumann and Schweighofer. We also solve the open problems from that
work. We further prove some helpful facts which can not be found in the
existing literature, for example that the closure of a projection of a
spectrahedron is again such a projection. We give a unified account of several
results on convex hulls of curves and images of polynomial maps. We finally
prove a Positivstellensatz for projections of spectrahedra, which exceeds the
known results that only work for basic closed semialgebraic sets.

We propose a video story question-answering (QA) architecture, Multimodal
Dual Attention Memory (MDAM). The key idea is to use a dual attention mechanism
with late fusion. MDAM uses self-attention to learn the latent concepts in
scene frames and captions. Given a question, MDAM uses the second attention
over these latent concepts. Multimodal fusion is performed after the dual
attention processes (late fusion). Using this processing pipeline, MDAM learns
to infer a high-level vision-language joint representation from an abstraction
of the full video content. We evaluate MDAM on PororoQA and MovieQA datasets
which have large-scale QA annotations on cartoon videos and movies,
respectively. For both datasets, MDAM achieves new state-of-the-art results
with significant margins compared to the runner-up models. We confirm the best
performance of the dual attention mechanism combined with late fusion by
ablation studies. We also perform qualitative analysis by visualizing the
inference mechanisms of MDAM.

structure at all, or the web server may internally rewrite parts of the URL.
This semantic disconnect between web browsers and web servers in interpreting
relative paths (path confusion) could be exploited by Relative Path Overwrite
(RPO). On the other hand, even tough extensions provide useful additional
functionality for web browsers, they are also an increasingly popular vector
for attacks. Due to the high degree of privilege extensions can hold,
extensions have been abused to inject advertisements into web pages that divert
revenue from content publishers and potentially expose users to malware.
In this thesis, I propose novel research into understanding and mitigating
the security risks of content inclusion in web browsers to protect website
publishers as well as their users.

The Wide-band All-sky Monitor (WAM) is a function of the large lateral BGO
shield of the Hard X-ray Detector (HXD) onboard Suzaku. Its large geometrical
area of 800 cm^2 per side, the large stopping power for the hard X-rays and the
wide-field of view make the WAM an ideal detector for gamma-ray bursts (GRBs)
observations in the energy range of 50-5000 keV. In fact, the WAM has observed
288 GRBs confirmed by other satellites, till the end of May 2007.

Current conditional functional dependencies (CFDs) discovery algorithms
always need a well-prepared training data set. This makes them difficult to be
applied on large datasets which are always in low-quality. To handle the volume
issue of big data, we develop the sampling algorithms to obtain a small
representative training set. For the low-quality issue of big data, we then
design the fault-tolerant rule discovery algorithm and the conflict resolution
algorithm. We also propose parameter selection strategy for CFD discovery
algorithm to ensure its effectiveness. Experimental results demonstrate that
our method could discover effective CFD rules on billion-tuple data within
reasonable time.

This is an investigation of "stacky" structures for Einstein gravity together
with an alternative reformulation in the language of formal moduli problems. In
the first part of the paper, we first revisit the aspects of (vacuum) Einstein
gravity on a Lorentzian 3-manifold $M$ with cosmological constant $\Lambda=0$.
Next, we shall provide a realization of the moduli space of Einstein's field
equations as a certain stack. We indeed construct the stack of (vacuum)
Einstein gravity in $n$-dimensional set-up with vanishing cosmological constant
by using the homotopy theoretical formulation of stacks. With this new
formulation, we also upgrade the equivalence of certain 2+1 quantum gravities
with gauge theory to the isomorphism between the corresponding moduli stacks.
The second part of the paper, on the other hand, is designed as a detailed
survey on formal moduli problems. It is in particular devoted to formalize
Einstein gravity in the language of formal moduli problems and to study the
algebraic structure of observables in terms of factorization algebras.

The reason that there are very different views in the Catholic Church (or in any institutional religion) is that each of us is at a different stage of spiritual growth. "Stages of Faith" by James Fowler and "Integral Spirituality" by Ken Wilbur are two books that speak extensively on this topic. Growing our souls and establishing a personal relationship with the ever present God/Yahweh/Allah/Mohammed/Buddha expands the inclusivity of our souls and widens our circle in regards to all of humankind and creation. Both of these books explain why some folks cling so tightly to 'their' religion and others are able to move forward.

Won't stay zipped.
This bag is as warm as advertised, but has a big issue. The zipper works very easy. Initially I thought this was a good thing, however it doesn't stay zipped and the velcro at the top of the zipper intended to keep is zipped is not strong enough to hold it in place. I have woke up on several cold nights freezing because the zipper had opened two feet or more.

The analysis method proposed in Ref. \cite{rotival07a} is applied to
characterize halo properties in finite many-fermion systems. First, the
versatility of the method is highlighted by applying it to light and
medium-mass nuclei as well as to atom-positron and ion-positronium complexes.
Second, the dependence of nuclear halo properties on the characteristics of the
energy density functional used in self-consistent Hartree-Fock-Bogoliubov
calculations is studied. It is found that (a) the low-density behavior of the
pairing functional and the regularization/renormalization scheme must be chosen
coherently and with care to provide meaningful predictions, (b) the impact of
pairing correlations on halo properties is significant and is the result of two
competing effects, (c) the detailed characteristics of the pairing functional
has however only little importance, (d) halo properties depend significantly on
any ingredient of the energy density functional that influences the location of
single-particle levels; i.e. the effective mass, the tensor terms and the
saturation density of nuclear matter. The latter dependencies give insights to
how experimental data on medium-mass drip-line nuclei can be used in the
distant future to constrain some characteristics of the nuclear energy density
functional. Last but not least, large scale predictions of halos among all
spherical even-even nuclei are performed using specific sets of particle-hole
and particle-particle energy functionals. It is shown that halos in the ground
state of medium-mass nuclei will only be found at the very limit of neutron
stability and for a limited number of elements.

Great observation.
I'm a slow typist.
I learned that if I send an e-mail to someone, I tend to be more reflective and more civil than if I call them up and leave a message, simply because it takes me more time to type than to speak, and thus a chance to slow down.

Stable and switchable polarization of ferroelectric materials opens a
possibility to electrically control their functional behavior. A particularly
promising approach is to employ ferroelectric tunnel junctions where the
polarization reversal in a ferroelectric barrier changes the tunneling current
across the junction. Here, we demonstrate the reproducible tunneling
electroresistance effect using a combination of Piezoresponse Force Microscopy
(PFM) and Conducting Atomic Force Microscopy (C-AFM) techniques on
nanometer-thick epitaxial BaTiO3 single crystal thin films on SrRuO3 bottom
electrodes. Correlation between ferroelectric and electronic transport
properties is established by the direct nanoscale visualization and control of
polarization and tunneling current in BaTiO3 films. The obtained results show a
change in resistance by about two orders of magnitude upon polarization
reversal on a lateral scale of 20 nm at room temperature. These results are
promising for employing ferroelectric tunnel junctions in non-volatile memory
and logic devices, not involving charge as a state variable.

A non-canonical scalar tachyon field is a viable candidate for dark energy
and has been found to be in good agreement with observational data. Background
data alone cannot completely rule out degeneracy between this model and others.
To further constrain the parameters, apart from the distance measurements, we
study perturbations in the tachyon scalar field and how they affect matter
clustering. We consider two tachyon potentials for this study, an inverse
square potential and an exponential potential. We study the evolution of the
gravitational potential, matter density contrast, and dark energy density
contrast, and compare them with the evolution in the $\Lambda CDM $ model.
Although perturbations in dark energy at sub-Hubble scales are negligible in
comparison with matter perturbations, they cannot be ignored at Hubble and
super-Hubble scales ($\lambda_p > 1000$ Mpc). We also study the evolution of
growth function and growth rate of matter, and find that the growth rate is
significantly suppressed in dark energy dominated era with respect to the
growth rate for $\Lambda CDM$ model. A comparison of these models with Redshift
Space Distortion growth rate data is presented by way of calculating
$f\sigma_8(z)$. There is a tension of $2.9\sigma$ ($2.26\sigma$ ) between
growth rate data and Planck-2015 (Planck-2018) Cosmic Microwave Background
Radiation data for $\Lambda CDM$ model. We present constraints on free
parameters of these models and show that perturbations in the tachyon scalar
field reduce this tension between different data sets.

Glashow and Cohen make the interesting observation that certain proper
subgroups of the Lorentz group like HOM(2) or SIM(2) can explain many results
of special relativity like time dilation, relativistic velocity addition and a
maximal isotropic speed of light. We show here that such SIM(2) and HOM(2)
based VSR theories predict an incorrect value for the Thomas precession and are
therefore ruled out by observations. In VSR theories the spin-orbital coupling
in atoms turn out to be too large by a factor of 2. The Thomas-BMT equation
derived from VSR predicts a precession of electrons and muons in storage rings
which is too large by a factor of $10^3$. VSR theories are therefore ruled out
by observations.

We prove that, for every function $f:\mathbb{N} \rightarrow \mathbb{N}$,
there is a graph $G$ with uncountable chromatic number such that, for every $k
\in \mathbb{N}$ with $k \geq 3$, every subgraph of $G$ with fewer than $f(k)$
vertices has chromatic number less than $k$. This answers a question of
Erd\H{o}s, Hajnal, and Szemeredi.

Discontinuities in elastic constants are detected at the superconducting
transition of layered organic conductors \kappa-(BEDT-TTF)_{2}X by longitudinal
and transverse ultrasonic velocity measurements. Symmetry arguments show that
discontinuities in shear elastic constants can be explained in the orthorhombic
compound only if the superconducting order parameter has a mixed character that
can be of two types, either A_{1g}+B_{1g} or B_{2g}+B_{3g} in the
classification of irreducible representations of the orthorhombic point group
D_{2h}. Consistency with other measurements suggests that the A_{1g}+B_{1g}
(d_{xy}+d_{z(x+y)}) possibility is realized. Such clear symmetry-imposed
signatures of mixed order parameters have not been observed in other
superconducting compounds.

Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot
treat phase off-diagonal effects, and thus not explain Bell inequality
violations. We describe another situation that is beyond a SSB treatment: an
experiment where particles from two (possibly macroscopic) condensate sources
are used for conjugate measurements of the relative phase and populations.
Off-diagonal phase effects are characterized by a "quantum angle" and observed
via "population oscillations", signaling quantum interference of
macroscopically distinct states (QIMDS).

Novel machine learning computational tools open new perspectives for quantum
information systems. Here we adopt the open-source programming library
TensorFlow to design multi-level quantum gates including a computing reservoir
represented by a random unitary matrix. In optics, the reservoir is a
disordered medium or a multi-modal fiber. We show that trainable operators at
the input and the readout enable one to realize multi-level gates. We study
various qudit gates, including the scaling properties of the algorithms with
the size of the reservoir. Despite an initial low slop learning stage,
TensorFlow turns out to be an extremely versatile resource for designing gates
with complex media, including different models that use spatial light
modulators with quantized modulation levels.

Best out there so far, with one issue
These switches work well for my home automation system that includes zwave capability. They have worked well with daily use over a year now and seem quite durable. I have these on 4 fans in my house. Relatively easy to install and no issues setting them up. The issue I have is that you cannot determine the fan speed visually at the switch. You can barely tell if its on or off and you just have to guess at the speed. Since it just has the 3 speed settings, much like many manual controls that easily show this, I just cannot understand how they missed some method to show current speed. I guess 3 more LEDs would have broke the budget.

We study a model for pair interaction $U$ of DNA molecules generated by the
discrete dipole moments of base-pairs and the charges of phosphate groups, and
find noncommutative group of eighth order ${\cal S}$ of symmetries that leave
$U$ invariant. We classify the minima using group ${\cal S}$ and employ
numerical methods for finding them. The minima may correspond to several
cholesteric phases, as well as phases formed by cross-like conformations of
molecules at an angle close to $\rm{90}^{o}$, "snowflake phase". The results
depend on the effective charge $Q$ of the phosphate group which can be modified
by the polycations or the ions of metals. The snowflake phase could exist for
$Q$ above the threshold $Q_C$. Below $Q_C$ there could be several cholesteric
phases. Close to $Q_C$ the snowflake phase could change into the cholesteric
one at constant distance between adjacent molecules.

I have a grandfather whom I never met nor have I ever seen in a photograph. That's because he died in prison for having put a shotgun blast through my grandmother in a jealous rage that was witnessed by my father and several of his young siblings. My grandparents' names were assiduously scrubbed from the family lore in an effort to spare my orphaned father the shame and horror he struggled with on a daily basis from that life-altering event. That revisionist history stood for a very long time.
So, yes, show me that framed photograph so I can learn from it and deal with it on my own terms. You're not entitled to deny me the truth. No one is.

The elliptical range theorem asserts that the field of values (or numerical
range) of a two-by-two matrix with complex entries is an elliptical disk, the
foci of which are the eigenvalues of the given matrix. Many proofs of this
result are available in the literature, but most, with one exception, are
computational and quite involved. In this note, it is shown that the elliptical
range theorem follows from the properties of plane algebraic curves and a
straightforward application of a well-known result due to Kippenhahn.

This chapter will first present a principal-agent game-theoretic model to
capture the interactions between one insurer and one user. The insurer is
deemed as the principal who does not have incomplete information about user's
security policies. The user, which refers to the infrastructure operator or the
customer, implements his local protection and pays a premium to the insurer.
The insurer designs an incentive compatible insurance mechanism that includes
the premium and the coverage policy, while the user determines whether to
participate in the insurance and his effort to defend against attacks. The
chapter will also focus on an attack-aware cyber insurance model by introducing
the adversarial behaviors into the framework. The behavior of an attacker
determines the type of cyber threats, e.g. denial of service (DoS) attacks,
data breaches, phishing and spoofing. The distinction of threat types plays a
role in determining the type of losses and the coverage policies. The data
breaches can lead to not only financial losses but also damage of the
reputations. The coverage may only cover certain agreed percentage of the
financial losses.

Before this little black-and-whiter, the touchy topic of criminal rape never made it onto the American screen.There were lots of these topics that Hollywood and the Production Code kept hidden until the rebellious 1960's. So it's not surprising that it would take a little independent company like Ida Lupino's Filmmakers to raise the subject. The result is well-meaning but somewhat compromised, which is not surprising since director Lupino had to work with Code demands to get the movie released.<br /><br />Interestingly, Ann Walton's (Mala Powers) main problem following the assault is not how others might see her, but how she sees herself. And it's a heavy load she's carrying. Will she ever be able to relate to men again? Will they look at her as "spoiled goods" (after all, this is 1950)? Small wonder she runs away rather than face these anxieties at home and at work, even though family and friends are generally supportive. Overall, this first part is earnest and well-done. The chase is hyped to inject some action into the plot, but then this is a movie-- notice how the incurious neighbor fails to respond to the honking horn near chase's end. Had those been screams of alarm from Powers instead, the neighbor's lack of response would have raised an interesting albeit complicating issue.<br /><br />The second half is pretty much given over to the Production Code in the sentimentalized person of Rev. Ferguson (Tod Andrews). It's he (to quote a phrase) who "gives her courage to face life again". There's some effort at humanizing him-- is it Ann or her dilemma that he's most interested in. Still, his gentle and understanding presence comes across as a little too miraculous and a little too Hollywood. Fortunately, the ending avoids the usual Hollywood cop-out by emphasizing only the hope of a happy resolution for Ann rather than its certainty. <br /><br />Give Lupino a ton of credit for dealing with the topic in the first place. Given the overall results, I expect she dealt as honestly with the topic as she was allowed to. I also expect today's audiences find the treatment mildly interesting mainly because of Powers' excellent performance that brings out the purely human drama. However, the film works best now as a document of its time, and what the cultural watchdogs of that day thought was appropriate for adult viewing.

Nice product, does what it sets out to do
This usbc adapter works well, you'll need to hook it up to a power supply when using it with a phone, but it charges your device and allows you to hook up other media to it/from it. Overall a good product with a nice feel from its metal exterior!

Modern neural sequence generation models are built to either generate tokens
step-by-step from scratch or (iteratively) modify a sequence of tokens bounded
by a fixed length. In this work, we develop Levenshtein Transformer, a new
partially autoregressive model devised for more flexible and amenable sequence
generation. Unlike previous approaches, the atomic operations of our model are
insertion and deletion. The combination of them facilitates not only generation
but also sequence refinement allowing dynamic length changes. We also propose a
set of new training techniques dedicated at them, effectively exploiting one as
the other's learning signal thanks to their complementary nature. Experiments
applying the proposed model achieve comparable performance but much-improved
efficiency on both generation (e.g. machine translation, text summarization)
and refinement tasks (e.g. automatic post-editing). We further confirm the
flexibility of our model by showing a Levenshtein Transformer trained by
machine translation can straightforwardly be used for automatic post-editing.

A waste of money.
I have ordered two of these remotes because the first one lasted only a few weeks. I hoped I had just received a lemon the first time; so, I tried it again and ordered a second one. It too was very poor quality. The buttons stick and fall off. The remote is completely unusable. Save your money and look elsewhere for a remote control.

The joint bidiagonalization(JBD) process is a useful algorithm for the
computation of the generalized singular value decomposition(GSVD) of a matrix
pair. However, it always suffers from rounding errors, which causes the Lanczos
vectors to loss their mutual orthogonality. In order to maintain some level of
orthongonality, we present a semiorthogonalization strategy. Our rounding error
analysis shows that the JBD process with the semiorthogonalization strategy can
ensure that the convergence of the computed quantities is not affected by
rounding errors and the final accuracy is high enough. Based on the
semiorthogonalization strategy, we develop the joint bidiagonalization process
with partial reorthogonalization(JBDPRO). In the JBDPRO algorithm,
reorthogonalizations occur only when necessary, which saves a big amount of
reorthogonalization work compared with the full reorthogonalization strategy.
Numerical experiments illustrate our theory and algorithm.

By Donald Gilpin
With overcrowding and increasing enrollments throughout the district, the Princeton Public Schools (PPS) have been looking for room to grow and paying attention to the changing plans of their neighbor just across Walnut Lane, the Westminster Choir College campus of Rider University.
When Rider University recently announced plans to close the Westminster site in Princeton and relocate the school to its Lawrenceville campus, protests ensued, and two pending lawsuit may prevent the University from moving the school.
At last month’s PPS Board of Education (BOE) meeting, Superintendent Steve Cochrane cited growth projections of several hundred students for the district over the next five years and emphasized the challenges of managing and finding space for that growth.
“We need to plan for that growth in ways that consider numerous factors, including facility and play area expansion, land use throughout the community, sustainability, potential redistricting, educational vision, and, of course, affordability
and diversity,” he said.
Speaking specifically about the possible availability of the property currently occupied by Westminster, Cochrane continued, “As stewards for the Princeton Public Schools, we have a responsibility to be prepared for that possibility and for the implications of having potentially 23 acres of land become available immediately next door to our middle school and high school. Consequently, we have been doing our homework.”
Cochrane stated that the PPS and Rider, with their lawyers, have had several “fact-finding” conversations over the past six months “to gain a better sense of the legal issues relating to the property as well as the proposed move of the Choir College to Lawrenceville.”
“The Choir College has been a great neighbor and partner to our schools for decades,” Cochrane continued. “We often share facilities, and for years students from the Choir College taught music at our middle school. If the Choir College were to remain in Princeton, we would be delighted to continue that partnership.”
Cochrane noted that Rider currently intends to keep a portion of the property and
buildings in Princeton for certain activities related to Westminster, including the Westminster Conservatory of Music, which educates more than 2,000 children and adults.
Cochrane went on to explain that PPS will be undergoing an extensive community-wide planning process over the next six months, considering multiple scenarios. “What those scenarios will be, when the Board will decide, and the timeline for implementation of any single scenario is yet to be determined. As we move into community conversations about the future of our schools and of our town, the Westminster property, or some portion of it, will likely be discussed.”
PPS Planning
Emphasizing that the planning process had no preconceived outcomes, would generate multiple possibilities, and would involve the whole community, Cochrane reviewed three stages to take place between now and June 2020 in collaboration with the planning firm Milone & MacBroom (M&M).
In the initial fact-finding stage, through January, M&M is reviewing enrollment projections, housing growth, the status of district facilities, building capacity, and educational programming.
From the end of January through March, M&M will be developing various scenarios in collaboration with the Board, the community, and district professionals “to generate a vision for our schools, to prioritize needs, and to review preliminary alternatives for achieving our goals,” Cochrane said.
From April to early June, the planners will narrow down the scenarios and provide a range of recommendations.
Cochrane pointed out that there are three elements involved in the critical process of ongoing community engagement and input.
A technical advisory committee, a kind of steering committee comprised of district professionals and community experts, will help the consultants navigate the complexities of the planning process. Their first meeting with M&M will be on Friday, January 10.
With a goal of ensuring that all voices are heard — and that people are informed and engaged — a group of community liaisons will also be formed, representing a variety of stakeholders throughout the community.
The third element of community engagement will be a series of interactive workshops, informational meetings, surveys, and focus groups.
The first public forum will be held on Saturday, January 25, from 9 to 10:30 a.m., in the Princeton High School cafeteria. During that workshop, the M&M consultants will present their findings and impressions so far and engage the attendees to work together to establish goals and priorities.

La Teta y la Luna is a symbolic spain film. Everything that in this film occurs has a symbolic meaning. It is totally different to the usual movie that one has access.<br /><br />This film is good but it will be good only for the people who want look for the meaning of everything in the film's tale. I must advice that this is not a sample film.<br /><br />Please enjoy!!!

Good value for what you get but could come defective.
Looked forward to giving this to my boyfriend for his birthday. He opened it today and we noticed there’s what appears to be some kind of burn marks on the knurling. $100 for a barbell is a great price especially considering how much weight this holds but I’m disappointed it came like that. Had it been some dings to the actual metal I’d just write it off but I’d like to be able to keep the knurling in tact for as long as possible, not damaged right out of the box. 2 stars.. I’ve reached out to them hopefully they make it right.

What is wrong with questions? You may think you have better ones. Everybody thinks their questions are the best."start asking better ones" Does this statement promote reconciliation and promote interaction? To me the statement makes the gap wider and attempts to tell people their opinions are not of value. Smacks of what happened in Residential Schools.

Although there are many neural network (NN) algorithms for prediction and for
control, and although methods for optimal estimation (including filtering and
prediction) and for optimal control in linear systems were provided by Kalman
in 1960 (with nonlinear extensions since then), there has been, to my
knowledge, no NN algorithm that learns either Kalman prediction or Kalman
control (apart from the special case of stationary control). Here we show how
optimal Kalman prediction and control (KPC), as well as system identification,
can be learned and executed by a recurrent neural network composed of
linear-response nodes, using as input only a stream of noisy measurement data.
The requirements of KPC appear to impose significant constraints on the
allowed NN circuitry and signal flows. The NN architecture implied by these
constraints bears certain resemblances to the local-circuit architecture of
mammalian cerebral cortex. We discuss these resemblances, as well as caveats
that limit our current ability to draw inferences for biological function. It
has been suggested that the local cortical circuit (LCC) architecture may
perform core functions (as yet unknown) that underlie sensory, motor,and other
cortical processing. It is reasonable to conjecture that such functions may
include prediction, the estimation or inference of missing or noisy sensory
data, and the goal-driven generation of control signals. The resemblances found
between the KPC NN architecture and that of the LCC are consistent with this
conjecture.

The main goal of our work is to formally prove the correctness of the key
commands of the SCHUR software, an interactive program for calculating with
characters of Lie groups and symmetric functions. The core of the computations
relies on enumeration and manipulation of combinatorial structures. As a first
"proof of concept", we present a formal proof of the conjugate function,
written in C. This function computes the conjugate of an integer partition. To
formally prove this program, we use the Frama-C software. It allows us to
annotate C functions and to generate proof obligations, which are proved using
several automated theorem provers. In this paper, we also draw on methodology,
discussing on how to formally prove this kind of program.

I used two of them and threw them in the washing machine. Was told I could. But when removing them after washing found the edges are unraveling. Now just threads from the edges. How do you avoid this? I only have one left that is any good. Sitting down and cutting off the threads from the edges was not something I was planning to do.

In recent work, we studied the problem of causally reconstructing time
sequences of spatially sparse signals, with unknown and slow time-varying
sparsity patterns, from a limited number of linear "incoherent" measurements.
We proposed a solution called Kalman Filtered Compressed Sensing (KF-CS). The
key idea is to run a reduced order KF only for the current signal's estimated
nonzero coefficients' set, while performing CS on the Kalman filtering error to
estimate new additions, if any, to the set. KF may be replaced by Least Squares
(LS) estimation and we call the resulting algorithm LS-CS. In this work, (a) we
bound the error in performing CS on the LS error and (b) we obtain the
conditions under which the KF-CS (or LS-CS) estimate converges to that of a
genie-aided KF (or LS), i.e. the KF (or LS) which knows the true nonzero sets.

The bond dissociation energies of a set of 44 3d transition metal-containing
diatomics are computed with phaseless auxiliary-field quantum Monte Carlo
(ph-AFQMC) utilizing a correlated sampling technique. We investigate molecules
with H, N, O, F, Cl, and S ligands, including those in the 3dMLBE20 database
first compiled by Truhlar and co-workers with calculated and experimental
values that have since been revised by various groups. In order to make a
direct comparison of the accuracy of our ph-AFQMC calculations with previously
published results from 10 DFT functionals, CCSD(T), and icMR-CCSD(T), we
establish an objective selection protocol which utilizes the most recent
experimental results except for a few cases with well-specified discrepancies.
With the remaining set of 41 molecules, we find that ph-AFQMC gives robust
agreement with experiment superior to that of all other methods, with a mean
absolute error (MAE) of 1.4(4) kcal/mol and maximum error of 3(3) kcal/mol
(parenthesis account for reported experimental uncertainties and the
statistical errors of our ph-AFQMC calculations). In comparison, CCSD(T) and
B97, the best performing DFT functional considered here, have MAEs of 2.8 and
3.7 kcal/mol, respectively, and maximum errors in excess of 17 kcal/mol for
both methods. While a larger and more diverse data set would be required to
demonstrate that ph-AFQMC is truly a benchmark method for transition metal
systems, our results indicate that the method has tremendous potential,
exhibiting unprecedented consistency and accuracy compared to other approximate
quantum chemical approaches.

Nuri Bilge Ceylan's 2002 film Distant (Uzak)- his third feature film (his first was 1997's black and white The Small Town- Kasaba), is a significant step up from his good but flawed 1999 film Clouds Of May (Mayis Sikintisi). The earlier film had potential, but reeked of a small budget and improvised quality in the worst ways- plot holes and wooden acting from amateurs. That Clouds Of May succeeded on any level was a testament to Ceylan's talent as a budding filmmaker. However, Distant is Ceylan's arrival on the international scene as a great artist, one who has many of the same qualities as other great filmmakers like Ingmar Bergman (although his screenplay is not as dialogue-heavy it is just as brooding, and he lacks Bergman's penchant for close-ups- his shots are usually long shots for exteriors and medium shots for interiors) and Yasujiro Ozu (whose penetrating scenes of contemplation Ceylan reconfigures). The bulk of the film takes place in snowy hibernal Istanbul (the fact that it snows in Turkey will likely surprise some), which lends the film a definite Bergmanian feel, as well as reminding one of some of the bleak snowy urban images from Krzysztof Kieslowski's The Decalogue. The natural images invoke the best of Werner Herzog- as they tend to go on a beat or two longer than standard film theory would dictate- which is what makes them even more memorable, while the urban landscapes range from the nearly Precisionist compositions of Michelangelo Antonioni to the cultural hagiography of Woody Allen- one shot of a bench overlooking water is a direct quotation (read steal) from Manhattan, save the lack of the Brooklyn Bridge in the background. In another scene, Ceylan similarly quotes a famous shot of a ship in the harbor from Ozu's Tokyo Story. Yet, like all great artists, Ceylan makes his appropriations his own art, by slightly altering them and keeping them apropos to his own film's needs
. Distant is a film whose title suffuses the characterization within the film and the feeling some viewers will have toward them, but it does not describe the film itself, for scenes stay with one long after the film ends. Perhaps the most memorable scene and image of the film comes when Mahmut stalks his ex-wife at the Istanbul airport, and watches her with her new husband as they head to board the plane that will remove her from his life forever. As he watches her, from a distance, we see her catch just a glance of him watching her. Will she leave her husband and return to Mahmut? Not in this film. He pulls back behind a column, and Nazan merely turns her head back to her future. Mahmut is her past, and she knows how to best move on- just keep moving. Mahmut will never get it. Most rarely get such moments of insight into themselves of life. That some viewers will get the film, and that Ceylan gets his own powers of creation, shows that ignorance can teach, as long as one moves about it. Distant does, albeit it at just the right length.

Loved it at first...
Got this to keep track of how much I practice. Worked very well and loved it at first. However, it appears to be broken now. I've tested it multiple times. It is suddenly twice as fast as a normal clock so if you set a minute on both, by the time the timer is done, my phone timer still has 30 seconds left. Loved using it but it is pretty much worthless if it can't properly keep track of time.

NNNNNNOOOOOOOOOOO!!!!!!!!!!!! The whole lesson of the US disaster is that when the government regulates the financial sector, and GUARANTEES that depositors will get paid, regardless of the idiotic loans made by said financial sector, depositors are not careful, and banks don't care about loan quality. Why would they? They get paid on volume, they bundle crap loans into MBSs and sell them to UBS, or they keep the loans on their books, but cover their butts with fed-backed mortgage insurance.
Just make it clear that unregulated means "not bailed out," and if investors then want to fund such firms to chase high returns, hey good luck to them!
Please google CountryWide, IndyMac, Washington Mutual, or 100 other dead lenders in the US...

In this paper we introduce a new approach to the study of the effects that an
impulsive wave, containing a mixture of material sources and gravitational
waves, has on a geodesic congruence that traverses it. We find that the effect
of the wave on the congruence is a discontinuity in the B-tensor of the
congruence. Our results thus provide a detector independent and covariant
characterization of gravitational memory.

Bad experience...
Do yourself a favor...go buy some real ginger root and use a grater!! I have used capsules from this company before with good results. But this bottle of capsules gave me pain in my intestinal tract and throat within a half hour of each dose...no matter how much water I drank to take them with. Recently I was having a particular bad digestive day after eating out. I took 1 pill 4 times within the day. That night I woke up with frightening gnawing pain (like before only way worse)...in my stomach and chest. I went out later and bought some real ginger root in the produce section of my grocery store...made some ginger tea and added some to my meals...and BINGO...best idea I ever had. The trouble with capsules is you never know what you are actually getting...but with real food it’s hard to deny!

Nuclear magnetic resonance and magnetization measurements were used to probe
the magnetic features of single-crystalline Bi(Cu(1-x)Znx)2PO6 with 0<x<0.05 at
temperatures between 2.6 K and 300 K. The simple lineshape of the 31P NMR
signals of the pristine compound changes considerably for x>0 and we present
clear evidence for a temperature dependent variation of the local magnetization
close to the Zn sites. The generic nature of this observation is indicated by
results of model calculations on appropriate spin systems of limited size
employing QMC methods.

We report a theoretical study of the electromagnetic waves (EWs) propagation
through an array of superconducting qubits, i.e. coherent two-level systems,
embedded in a low-dissipative transmission line. We focus on the near-resonant
case as the frequency of EWs $\omega \simeq \omega_q$, where $\omega_q$ is the
qubit frequency. In this limit we derive the effective dynamic nonlinear wave
equation allowing one to obtain the frequency dependent transmission
coefficient of EWs, $D(\omega)$. In the linear regime and a relatively wide
frequency region we obtain a strong resonant suppression of $D(\omega)$ in both
cases of a single qubit and chains composed of a large number of densely
arranged qubits. However, in narrow frequency regions a chain of qubits allows
the resonant transmission of EWs with greatly enhanced $D(\omega)$. In the
nonlinear regime realized for a moderate power of applied microwave radiation,
we predict and analyze various transitions between states characterized by high
and low values of $D(\omega)$. These transitions are manifestations of
nonequilibrium steady states of an array of qubits achieved in this regime.

Great for mixing and matching
I ordered these as a gift for my sister-in-law who only wears ankle socks and loves this particular brand. She seemed very pleased with them as she loves to mix and match; she never wears matching socks and loves all the bold and bright patterns. Thank you!!

You make accusations without any bases in truth, that is false witness, like when you accuse me of working for CI. Your soul is red with hatred, and risk your own soul friend.
The devil was never after those children, but those souls who burn with hatred afterwards.
Remember that the church can't send people to jail, it can't prosecute. Victims need to go to the police. You can't blame the church for not imprisoning offenders.
Again, remember Judas Iscariot, he was hand picked by Christ and ended up being a thief and a traitor. The devil didn't want Judas, he wants to embroil as many souls as possible with hatred. If the disciples ended up embittered with hatred towards Judas, then the spread of the message stops. Fortunately the Holy Spirit's power of love and forgiveness heals.
I pray you sole mission isn't to spread hatred of the church, it will not end for you. We know the church will have an apostasy when Christ returns, and he then takes the church into heaven.

In this paper we describe the notion of a weak lipschitzianity of a mapping
on a $C^{q}$ stratification. We also distinguish a class of regularity
conditions that are in some sense invariant under definable, locally Lipschitz
and weakly bi-Lipschitz homeomorphisms. This class includes the Whitney (B)
condition and the Verdier condition.

Given any closed Kaehler manifold we define, following an idea by Eugenio
Calabi, a Riemannian metric on the space of Kaehler metrics regarded as an
infinite dimensional manifold. We prove several geometrical features of the
resulting space, some of which we think were already known to Calabi. In
particular, the space is a portion of an infinite dimensional sphere and admits
explicit unique smooth solutions for the Cauchy and the Dirichlet problems for
the geodesic equation.

Similarly to the larger Galactic ridge, the Galactic center region presents a
hard diffuse emission whose origin has been strongly debated for the past two
decades: does this emission result from the contribution of numerous, yet
unresolved, discrete point sources ? Or does it originate in a truly diffuse,
hot plasma ?
The Galactic center region (GC) is however different on many respects from
the outer parts of the Galaxy, which makes the diffuse emission issue at the
Galactic center unique. Although recent observations seem to favour a point
sources origin in the far Galactic ridge, the situation is still unclear at the
GC and new observations are required.
Here we present results on the modeling of the truly diffuse plasma.
Interestingly, such a plasma would strongly affect the dynamics of orbiting
molecular clouds and thus the central engine activity. Discriminating between
the two hypothesis has thus become a crucial issue in the understanding of this
central region that makes the link between the inner small accretion disk and
the large scale Galactic dynamics. We investigate the new inputs we can expect
from Simbol-X on this matter.

Muscadinia rotundifolia cv. Trayshed is a valuable source of resistance to grape powdery mildew. It carries two powdery mildew resistance-associated genetic loci, Run1.2 on chromosome 12 and Run2.2 on chromosome 18. In this study, we identified, phased, and reconstructed the two haplotypes of each resistance-associated locus. Haplotype phasing allowed the identification of several structural variation events between haplotypes of both loci. Combined with manual refinement of the gene models, we found that the heterozygous structural variants affected the gene content, with some resulting in duplicated or hemizygous nucleotide-binding leucine-rich repeat (NLR) genes. Structural variations also impacted the domain composition of some NLRs. These findings emphasize the need of generating haplotype-resolved sequences instead of using consensus sequences for identifying haplotype-specific candidate genes. Comparison of the NLRs in the Run1.2 and Run2.2 loci indicated that the two loci are composed of a different number and classes of NLR genes. We provide a list of candidate NLR genes from the Run1.2b and Run2.2 loci, whose expression suggests a role in powdery mildew resistance in Trayshed. These first complete and haplotype-resolved resistance-associated loci, and their candidate NLR genes, represent new resources to develop powdery mildew-resistant grape cultivars.

A search for muon neutrinos from Kaluza-Klein dark matter annihilations in
the Sun has been performed with the 22-string configuration of the IceCube
neutrino detector using data collected in 104.3 days of live-time in 2007. No
excess over the expected atmospheric background has been observed. Upper limits
have been obtained on the annihilation rate of captured lightest Kaluza-Klein
particle (LKP) WIMPs in the Sun and converted to limits on the LKP-proton
cross-sections for LKP masses in the range 250 -- 3000 GeV. These results are
the most stringent limits to date on LKP annihilation in the Sun.

It is possible to learn about the orientation of a star's rotation axis by
combining measurements of the star's rotation velocity ($v$) and its projection
onto our line of sight ($v\sin i$). This idea has found many applications,
including the investigation of the obliquities of stars with transiting
planets. Here, we present a method for the probabilistic inference of the
inclination of the star's rotation axis based on independent data sets that
constrain $v$ and $v\sin i$. We also correct several errors and misconceptions
that appear in the literature.

% context We had detected J=1-0 HCO+ absorption in 12 directions lacking
detected CO emission in the outskirts of the Chamaeleon complex and on 1
sightline with integrated CO emission 2.4 K-\kms. 8 sightlines had a much
larger mean column density of dark neutral medium (DNM)-gas not represented in
H I or CO emission-and were found to have much higher mean molecular column
density. The 5 other sightlines had little or no DNM and were found to have
much smaller but still detectable N(HCO+). % aims To determine N(CO) along
previously-observed Chamaeleon sightlines and to determine why CO emission was
not detected in directions where molecular gas is present. % methods We took
\cotw\ J=1-0 absorption profiles on 5 sightlines having higher DNM and HCO+
column densities and 1 sightline with smaller N(DNM) and N(HCO+). We converted
the integrated HCO+ optical depths to N(H2) in the weak-excitation limit using
N(HCO+)/N(H2)$=3\times10^{-9}$ and converted the integrated CO optical depths
\ICO\ to CO column density N(CO) $= 1.861\times 10^{15}\pcc \ICO^{1.131}$ as
found along comparable lines of sight previously studied in J=1-0 and J=2-1 CO
absorption&emission. %results CO absorption was detected along the 5 sightlines
in the higher-DNM group, with CO column densities $4\times 10^{13} \pcc<$ N(CO)
$<10^{15}\pcc$ that are generally below the detectability limit of CO emission
surveys. %conclusions In the outskirts of the Chamaeleon complex, the presence
of molecular DNM resulted primarily from small CO column densities at the onset
of CO formation around the HI/\HH\ transition in diffuse molecular gas. CO
relative abundances N(CO)/N(H2) $< 2\times 10^{-6}$ in the outskirts of
Chamaeleon are comparable to those seen in UV absorption toward early-type
stars, including in Chamaeleon.

Comes close.
I tried to match my beige tiles given the beige and white, but all I could come up with close. I probably need some black to come closer. It seems to be essentially just tubes of paint. Anyway it was close enough that if I'm not looking for it, I won't spot it. I had two spots, a small ship and a deeper 1/2" gouge. The small chip covered OK, but the gouge kept sucking up the paint. I tried lining it with clear nail polish and then finally with glue when the gouge finally held the paint. There is still an indentation so I don't know whether the paint shrunk or whether it was still sucking up through all the layers of stuff I had previously put in there.

Need additional frame for tent to use !
Nice tent, but did I miss something with the fact the tent doesn’t come with everything you need for the tent to use . Must buy additional truss to hold tent up. Went out tonight for my 6 year old to camp in back yard and discovered there is no frame ! 😂😂😂

A GW approximation (GWA) method named U+GWA is proposed, where we can start
GWA with more localized wave functions obtained by the local spin-density
approximation (LSDA)+U method. Then GWA and U+GWA are applied to MnO, NiO, and
V$_2$O$_3$ in antiferromagnetic phase. The band gaps and energy spectra show an
excellent agreement with the experimentally observed results and are discussed
in details. The calculated width of d-bands of V$_2$O$_3$ is much narrower than
that of the observed one which may be a mixture of t$_{2g}^2$ multiplet and
single electron t$_{2g}$ level. GWA or U+GWA does not work also in the
paramagnetic phase of V$_2$O$_3$ and the reason for thois is clarified. The
method of the unique choice of on-site Coulomb interaction is discussed in
details. The criterion for whether we should adopt GWA or U+GWA is discussed
and is assessed with the help of the off-diagonal elements of the self-energy.

Yes, it's flawed - especially if you're into Hollywood films that demand a lot of effects, a purely entertaining or fantasy story or plot, and you can't actually think for yourself.<br /><br />Roeg's films are for the intelligent film-goer, and Insignificance is a perfect example.<br /><br />The characterizations are brilliant, the story is excellent, but, like all Nic Roeg's films - it has you thinking on every level about aspects of reality that would never have dawned on you before. His films always make you think, and personally, I like that in a film.<br /><br />So don't expect to come away from watching this film and feeling all happy-happy, because it's likely you'll be disappointed.<br /><br />But I think it's excellent.

We present an approach to numerical homogenization of the elastic response of
microstructures. Our work uses deep neural network representations trained on
data obtained from direct numerical simulation (DNS) of martensitic phase
transformations. The microscopic model leading to the microstructures is based
on non-convex free energy density functions that give rise to martensitic
variants, and must be extended to gradient theories of elasticity at finite
strain. These strain gradients introduce interfacial energies as well as
coercify the model, enabling the admission of a large number of solutions, each
having finely laminated microstructures. The numerical stiffness of these DNS
solutions and the fine scales of response make the data expensive to obtain,
while also motivating the search for homogenized representations of their
response for the purpose of engineering design. The high-dimensionality of the
problem is reduced by training deep neural networks (DNNs) on the effective
response by using the scalar free energy density data. The novelty in our
approach is that the trained DNNs also return high-fidelity representations of
derivative data, specifically the stresses. This allows the recapitulation of
the classic hyperelastic response of continuum elasticity via the DNN
representation. Also included are detailed optimization studies over
hyperparameters, and convergence with size of datasets.

Super-ASTROD (Super Astrodynamical Space Test of Relativity using Optical
Devices or ASTROD III) is a mission concept with 3-5 spacecraft in 5 AU orbits
together with an Earth-Sun L1/L2 spacecraft ranging optically with one another
to probe primordial gravitational-waves with frequencies 0.1 microHz - 1 mHz,
to test fundamental laws of spacetime and to map the outer solar system. In
this paper we address to its scientific goals, orbit and payload selection, and
sensitivity to gravitational waves.

Not badd but I had to make a change
I got this seeking it was the perfect fit in it should have been according to what I saw in the description of period what I ended up having to do was clip off the Velcro and double sided sticky tape it set a back farther so that I can fully close up and not blow off of the grill. Once I did that it works great and I love my blackhawks!

We prove a sharp degree bound for polynomials constant on a hyperplane with a
fixed number of distinct monomials for dimensions 2 and 3. We study the
connection with monomial CR maps of hyperquadrics and prove similar bounds in
this setup with emphasis on the case of spheres. The results support
generalizing a conjecture on the degree bounds to the more general case of
hyperquadrics.

Hmmm, started well, like a hybrid of X-Files & First Wave, unfortunately, if the mere notion of Da Vinci's lost time machine is preposterous to you, then the final 'battle' between one man with a pistol and 4 16th century monks armed to the teeth with automatic weapons will seem positively ridiculous equalled only by poor acting, poor script and screenplay, or, in other words, giggle factor 5 captain.
