Recent developments of the pump-probe thermoreflectance methods (such as the
beam-offset and elliptical-beam approaches of the time-domain and
frequency-domain thermoreflectance techniques) enabled measurements of the
thermal conductivities of in-plane anisotropic materials. Estimating the
temperature rise of anisotropic layered structures under surface heating is
critically important to make sure that the temperature rise is not too high to
alias the signals in these experiments. However, a simple formula to estimate
the temperature rise in three-dimensional (3D) anisotropic layered systems
heated by a non-circular laser beam is not available yet, which is the main
problem we aim to solve in this work. We first re-derived general formalisms of
the temperature rise of a multilayered structure based on the previous
literature work by solving the 3D anisotropic heat diffusion equation in the
frequency domain. These general formalisms normally require laborious numerical
evaluation; however, they could be reduced to explicit analytical expressions
for the case of semi-infinite solids. We then extend the analytical expressions
to multilayered systems, taking into account the effect of the top layers. This
work not only enhances our understanding of the physics of temperature rise due
to surface laser heating but also enables quick estimation of the peak
temperature rise of 3D anisotropic layered systems in pump-probe
thermoreflectance experiments and thus greatly benefits the thermoreflectance
experiments in choosing the appropriate heating power intensity for the
experiments.

The difference in Alaska's situation is that we have a Permanent Fund which can sustainably subsidize our State Government for about $2 Billion per year. Obviously I agree with you that taxes are unnecessary at this time. I would not object to a very low (1%) income tax along with the $100 school tax. That assumes the end of the Dividend with $3000 this year, the last year of the Dividend (as we know it).

Firstly, we consider Yang-Mills theory on ${\mathbb R}^{3,1}$ with an adjoint
Higgs field spontaneously breaking a compact gauge group $G$ to a subgroup $H$,
so that the Higgs vacuum manifold forms the coset $G/H$. It is shown that in
the low-energy limit, when the Higgs vacuum value is large, the 4d
Yang-Mills-Higgs theory reduces to the Faddeev sigma model on ${\mathbb
R}^{3,1}$ with $G/H$ as target. Its action contains the standard two-derivative
sigma-model term as well as the four-derivative Skyrme-type term, which
stabilizes solutions against scaling. Secondly, we put the Higgs field in the
bi-fundamental representation of $G=\textrm{U}_+(N)\times\textrm{U}_-(N)$,
realizing the simplest $A_2$-type quiver gauge theory. Breaking $G$ to
$H{=}\,\textrm{diag}(G)$, the vacuum manifold $G/H\cong\textrm{U}(N)$ is a
group. In this case, when the Higgs vacuum value is large, the 4d $A_2$-quiver
gauge theory reduces to the Skyrme sigma model on ${\mathbb R}^{3,1}$ with
U$(N)$ as target. Thus, both the Skyrme and the Faddeev model arise as
effective field theories in the infrared of Yang-Mills-Higgs models.

The strong dependence of the large-scale dark matter halo bias on the (local)
non-Gaussianity parameter, f_NL, offers a promising avenue towards constraining
primordial non-Gaussianity with large-scale structure surveys. In this paper,
we present the first detection of the dependence of the non-Gaussian halo bias
on halo formation history using N-body simulations. We also present an analytic
derivation of the expected signal based on the extended Press-Schechter
formalism. In excellent agreement with our analytic prediction, we find that
the halo formation history-dependent contribution to the non-Gaussian halo bias
(which we call non-Gaussian halo assembly bias) can be factorized in a form
approximately independent of redshift and halo mass. The correction to the
non-Gaussian halo bias due to the halo formation history can be as large as
100%, with a suppression of the signal for recently formed halos and
enhancement for old halos. This could in principle be a problem for realistic
galaxy surveys if observational selection effects were to pick galaxies
occupying only recently formed halos. Current semi-analytic galaxy formation
models, for example, imply an enhancement in the expected signal of ~23% and
~48% for galaxies at z=1 selected by stellar mass and star formation rate,
respectively.

Digital Watermarking is used for copyright protection and authentication. In
the proposed system, a Dual Watermarking Scheme based on DWT SVD with chaos
encryption algorithm, will be developed to improve the robustness and
protection along with security. DWT and SVD have been used as a mathematical
tool to embed watermark in the image. Two watermarks are embedded in the host
image. The secondary is embedded into primary watermark and the resultant
watermarked image is encrypted using chaos based logistic map. This provides an
efficient and secure way for image encryption and transmission. The watermarked
image is decrypted and a reliable watermark extraction scheme is developed for
the extraction of the primary as well as secondary watermark from the distorted
image.

In this paper, we study the asymptotic behavior of sums of functions of the
increments of a given semimartingale, taken along a regular grid whose mesh
goes to 0. The function of the $i$th increment may depend on the current time,
and also on the past of the semimartingale before this time. We study the
convergence in probability of two types of such sums, and we also give
associated central limit theorems. This extends known results when the summands
are a function depending only on the increments, and this is motivated mainly
by statistical applications.

Pairs of numerically computed trajectories of a chaotic system may coalesce
because of finite arithmetic precision. We analyse an example of this
phenomenon, showing that it occurs surprisingly frequently. We argue that our
model belongs to a universality class of chaotic systems where this numerical
coincidence effect can be described by mapping it to a first-passage process.
Our results are applicable to aggregation of small particles in random flows,
as well as to numerical investigation of chaotic systems.

After watching Awake,I led to a conclusion:director and screenwriter Joby Harold made Awake with the intention of laughing at the spectator,for the simple fact the movie is full of ridiculous elements.Awake has a lot of plot holes and it is full of absurd and ridiculous elements(for example,the hospital uniform the spirit of the main character uses...did the ghost of a doctor leave it in the floor ?).The concept behind this movie is slightly ingenious but all the plot holes and the absurd things make of this a stupid and crappy film.With the exception of the great Lena Olin,all the actors bring bad performances.Hayden Christensen has zero expressions and the same applies for Jessica Alba.The extraordinary actor Terrence Howard is enormously wasted on his role.Awake makes a laugh of the spectator.It's so ridiculous and full of absurd things that it's impossible to take it seriously.My recommendation is:skip this crappy movie.

We study space-time noncommutativity applied to the hydrogen atom and its
phenomenological effects. We find that it modifies the potential part of the
Hamiltonian in such a way we get the Kratzer potential instead of the Coulomb
one and this is similar to add a dipole potential or to consider the extended
charged nature of the proton in the nucleus. By calculating the energies from
the Schr\"odinger equation analytically and computing the fine structure
corrections using perturbation theory, we study the modifications of the
hydrogen spectrum. We find that it removes the degeneracy with respect to both
the orbital quantum number l and the total angular momentum quantum number j;
it acts here like a Lamb shift. Comparing the results with the experimental
values from spectroscopy, we get a new bound for the space-time non-commutative
parameter. We do the same perturbative calculation for the relativistic case
and compute the corrections of the Dirac energies; we find that in this case
too, the corrections are similar to a Lamb shift and they remove the degeneracy
with respect to j ; we get an other bound for the parameter of
non-commutativity.

Infallible logic: having not actually seen a child raped by a priest since your conversion, you correctly dismiss the many articles describing the abuse scandal. And because the chruch now publishes minimum standards for reporting abuse, one can safely conclude it has always had them, always followed them, and continues to do so. This is very much a bishop-sanctioned approach to defending the church's actual record of aiding and abetting child abuse.

The Deep Synoptic Array 10 dish prototype is an instrument designed to detect
and localise fast radio bursts with arcsecond accuracy in real time. Deployed
at Owens Valley Radio Observatory, it consists of ten 4.5m diameter dishes,
equipped with a 250MHz bandwidth dual polarisation receiver, centered at
1.4GHz. The 20 input signals are digitised and field programmable gate arrays
are used to transform the data to the frequency domain and transmit it over
ethernet. A series of computer servers buffer both raw data samples and perform
a real time search for fast radio bursts on the incoherent sum of all inputs.
If a pulse is detected, the raw data surrounding the pulse is written to disk
for coherent processing and imaging. The prototype system was operational from
June 2017 - February 2018 conducting a drift scan search. Giant pulses from the
Crab pulsar were used to test the detection and imaging pipelines. The 10-dish
prototype system was brought online again in March 2019, and will gradually be
replaced with the new DSA-110, a 110-dish system, over the next two years to
improve sensitivity and localisation accuracy.

We propose a minimal theoretical model for the description of a
two-dimensional (2D) strongly interacting Fermi gas confined transversely in a
tight harmonic potential, and present accurate predictions for its equation of
state and breathing mode frequency. We show that the minimal model Hamiltonian
needs at least two independent interaction parameters, the 2D scattering length
and effective range of interactions, in order to quantitatively explain recent
experimental measurements at nonzero filling factor $N/N_{2D}$, where $N$ is
the total number of atoms and $N_{2D}$ is the threshold number to reach the 2D
limit. We therefore resolve in a satisfactory way the puzzling experimental
observations of reduced equations of state and reduced quantum anomaly in
breathing mode frequency, due to small yet non-negligible $N/N_{2D}$. We argue
that a conclusive demonstration of the much-anticipated quantum anomaly is
possible at a filling factor of a few percent. Our establishment of the minimal
model for 2D ultracold atoms could be crucial to understanding the fermionic
Berezinskii-Kosterlitz-Thouless transition in the strongly correlated regime.

We study the inverse problem for the versal deformation rings $R(\Gamma,V)$
of finite dimensional representations $V$ of a finite group $\Gamma$ over a
field $k$ of positive characteristic $p$. This problem is to determine which
complete local commutative Noetherian rings with residue field $k$ can arise up
to isomorphism as such $R(\Gamma,V)$. We show that for all integers $n \ge 1$
and all complete local commutative Noetherian rings $\mathcal{W}$ with residue
field $k$, the ring $\mathcal{W}[[t]]/(p^n t,t^2)$ arises in this way. This
ring is not a local complete intersection if $p^n\mathcal{W}\neq\{0\}$, so we
obtain an answer to a question of M. Flach in all characteristics.

Doubly enhanced third harmonic generation (THG) is realized by the electric
dipole resonance (EDR) in silicon nanodisks placed onto a metallic film at
near-infrared. By introducing the metal substrate, the perfect electric
conductor (PEC) surface effect can be formed to not only enhance the electric
field in silicon, but also improve the near-field distribution. Meanwhile, in
consideration of the periodic nanostructure, the silicon nanodisk, acting as a
high-refractive-index dielectric grating, can generate a propagating surface
plasmon resonance (PSPR) on the metal surface. By flexibly manipulating the
array period, PSPR can effectively couple with EDR, which produces further
enhancement and novel properties for EDR. On account of the dual enhancements
from these two effects, it is demonstrated that the total THG conversion
efficiency of the proposed nanostructure is raised by more than eight orders of
magnitude as compared with that of the all-dielectric nanostructure. In
addition, the influence of silicon Kerr effect on the coupling and THG is
investigated as well, manifesting an unprecedent THG efficiency around 10^-2
with input internsity 2 GW/cm^2. This work will pave a new way for improving
the multipolar mode in metal-dielectric nanosturctures and facilitate its
engineered applications in nonlinear optics, e.g. frequency conversion,
spectroscopic and biochemical sensing.

A true story about a true revolution, 25 of April ; a revolution against a repressive regime of 41 years, that was imposing a colonial war on it's military's, for maintaining an empire (Angola, Mozambique, Guine-Bissau, Cabo Verde, S. Tomé e Principe; the first and the last of the great colonial empire's of Europe) of 600 years, since it's beginning in the conquest of Ceuta in 1415; a revolution by the army for the people, and for a democratic Portugal; the most's surprising fact in this revolution is that it were no people killed in it (except those that died in the hand's of PIDE, the political police of the State, during a brutal gunfire against an unarmed crowd protesting in front of it's headquarters in the day of the revolution, in 25 of April 1974, has it show's on the film).And has all revolutions it has it's heroes, one them of was Captain Salgueiro Maia, a returned soldier from the war, whose convictions along with the rest of the army, was that they were fighting (since 1961) a hopeless war, and that sometimes a soldier has to disobey it's country.

van Holten's algorithm is used to construct Runge-Lenz-type conserved
quantities, induced by Killing tensors, on curved manifolds. For the
generalized Taub-NUT metric, the most general external potential such that the
combined system admits a conserved Runge-Lenz-type vector is found. In the
multi-center case, the subclass of two-center metric exhibits a conserved
Runge-Lenz-type scalar.

Buy the real ones or sacrifice comfort
These installed easily and may work fine for the casual user. I probably wear my headphones 30 hours/week, and could tell immediately with one original and one replacement ear cushion on that these are more firm and don't conform to my head as well. If you don't plan on wearing these often or taking several flights/sleeping on planes in them MAYBE you want to roll the dice. Otherwise, heed this review and the others concerned with comfort, pony up $12 extra for the real ones and don't worry about regretting which ones you bought on your next hundred flights.

We establish that the set of pairs $(\alpha, \beta)$ of real numbers such
that $$ \liminf_{q \to + \infty} q \cdot (\log q)^2 \cdot \Vert q \alpha \Vert
\cdot \Vert q \beta \Vert > 0, $$ where $\Vert \cdot \Vert$ denotes the
distance to the nearest integer, has full Hausdorff dimension in $\R^2$. Our
proof rests on a method introduced by Peres and Schlag, that we further apply
to various Littlewood-type problems

If you are studying Welles and want to see just how far he fell after Citizen Kane, this film will prove it. The cheap excuse of making the protagonist a self-admitted dummy to explain how he might fall into such a half-baked scheme fails to explain the absurd courtroom theatrics and ridiculous plot twists that eventually ensue. Don't be taken in by the high rating of this film in the db as I was; all I can guess is that there are a lot of die hard old Welles and Hayworth fans out there.

Min, Veeravalli, and Barlas have recently proposed strategies to minimize the
overall execution time of one or several divisible loads on a heterogeneous
linear network, using one or more installments. We show on a very simple
example that their approach does not always produce a solution and that, when
it does, the solution is often suboptimal. We also show how to find an optimal
schedule for any instance, once the number of installments per load is given.
Then, we formally state that any optimal schedule has an infinite number of
installments under a linear cost model as the one assumed in the original
papers. Therefore, such a cost model cannot be used to design practical
multi-installment strategies. Finally, through extensive simulations we
confirmed that the best solution is always produced by the linear programming
approach, while solutions of the original papers can be far away from the
optimal.

We explore NOT gate response in a mesoscopic ring threaded by a magnetic flux
$\phi$. The ring is attached symmetrically to two semi-infinite one-dimensional
metallic electrodes and a gate voltage, viz, $V_a$, is applied in one arm of
the ring which is treated as the input of the NOT gate. The calculations are
based on the tight-binding model and the Green's function method, which
numerically compute the conductance-energy and current-voltage characteristics
as functions of the ring-to-electrodes coupling strength, magnetic flux and
gate voltage. Our theoretical study shows that, for $\phi=\phi_0/2$
($\phi_0=ch/e$, the elementary flux-quantum) a high output current (1) (in the
logical sense) appears if the input to the gate is low (0), while a low output
current (0) appears when the input to the gate is high (1). It clearly exhibits
the NOT gate behavior and this aspect may be utilized in designing an
electronic logic gate.

We consider liquid xenon dark matter detectors for searching a light scalar
particle produced in the solar core, specifically one that couples to
electrons. Through its interaction with the electrons, the scalar particle can
be produced in the Sun, mainly through Bremsstrahlung process, and subsequently
it is absorbed by liquid xenon atoms, leaving prompt scintillation light and
ionization events. Using the latest experimental results of XENON1T and Large
Underground Xenon, we place bounds on the coupling between electrons and a
light scalar as $g_{\phi ee} < 7 \times 10^{-15}$ from S1-only analysis, and as
$g_{\phi ee} < 2 \times 10^{-15}$ from S2-only analysis. These can be
interpreted as bounds on the mixing angle with the Higgs, $\sin \theta < 2
\times 10^{-9} \, \left(7 \times 10^{-10}\right)$, for the case of a relaxion
that couples to the electrons via this mixing. The bounds are a factor few
weaker than the strongest indirect bound inferred from stellar evolution
considerations.

The top-quark mass is one of the fundamental parameters of the Standard Model
of particle physics. The latest ATLAS measurements of the top-quark mass in top
quark pair final states are presented. Measurements use di-lepton, lepton+jets
and all-jets final states and their combination is performed. Measurements of
the top-quark pole mass based on precision theoretical QCD calculations for
lepton kinematic distribution and for top quark pair production with an
additional jet are also presented.

The Administrator will allocate to an opt-in unit an amount of allowances equal to fifty percent the lesser of the unit's baseline heat input or the unit's heat input for the year before the year for which the Administrator is determining the allocation; multiplied by the lesser of the unit's baseline emission rate, the unit's 2002 emissions rate, or the unit's most stringent State or federal emission limitation applicable to the year on which the unit's baseline heat input is based.

The axial form factor of the nucleon is studied in a two-component model
consisting of a three-quark intrinsic structure surrounded by a meson cloud.
The experimental data in the space-like region are well reproduced with a
minimal number of parameters. The results are similar to those obtained from a
dipole fit up to 1 GeV$^2$, but they surprisingly show a zero between 2 and 3
GeV$^2$. Such behavior, predicted by the present model completely disagrees
with the dipole parametrization. The theoretical expression for the form factor
is then analytically extrapolated to the time-like region, giving the first
predictions in this regime. This kinematical region is especially interesting
for present and future colliders.

In a class of beyond-standard-model theories, CP-odd observables, such as the
neutron electric dipole moment, receive significant contributions from
flavor-neutral P-odd and CP-odd four-quark operators. However, considerable
uncertainties exist in the hadronic matrix elements of these operators strongly
affecting the experimental constraints on CP-violating parameters in the
theories. Here we study their hadronic matrix elements in combined chiral
perturbation theory and nucleon models. We first classify the operators in
chiral representations and present the leading-order QCD evolutions. We then
match the four-quark operators to the corresponding ones in chiral hadronic
theory, finding symmetry relations among the matrix elements. Although this
makes lattice QCD calculations feasible, we choose to estimate the
non-perturbative matching coefficients in simple quark models. We finally
compare the results for the neutron electric dipole moment and P-odd and CP-odd
pion-nucleon couplings with the previous studies using naive factorization and
QCD sum rules. Our study shall provide valuable insights on the present
hadronic physics uncertainties in these observables.

The problem of simulating solid-state dewetting of thin films in three
dimensions (3D) by using a sharp-interface approach is considered in this
paper. Based on the thermodynamic variation, a speed method is used for
calculating the first variation to the total surface energy functional. The
speed method shares more advantages than the traditional use of parameterized
curves (or surfaces), e.g., it is more intrinsic and its variational structure
(related with Cahn-Hoffman $\boldsymbol{\xi}$-vector) is clearer and more
direct. By making use of the first variation, necessary conditions for the
equilibrium shape of the solid-state dewetting problem is given, and a kinetic
sharp-interface model which includes the surface energy anisotropy is also
proposed. This sharp-interface model describes the interface evolution in 3D
which occurs through surface diffusion and contact line migration. By solving
the proposed model, we perform lots of numerical simulations to investigate the
evolution of patterned films, e.g., the evolution of a short cuboid and
pinch-off of a long cuboid. Numerical simulations in 3D demonstrate the
accuracy and efficacy of the sharp-interface approach to capture many of the
complexities observed in solid-state dewetting experiments.

The aim of "A glance beyond the quantum model" [arXiv:0907.0372] to modernize
the Correspondence Principle is compromised by an assumption that a classical
model must start with the idea of particles, whereas in empirical terms
particles are secondary to events. The discussion also proposes,
contradictorily, that observers who wish to model the macroscopic world
classically should do so in terms of classical fields, whereas, if we are to
use fields, it would more appropriate to adopt the mathematics of random
fields. Finally, the formalism used for discussion of Bell inequalities
introduces two assumptions that are not necessary for a random field model,
locality of initial conditions and non-contextuality, even though these
assumptions are, in contrast, very natural for a classical particle model.
Whether we discuss physics in terms of particles or in terms of events and
(random) fields leads to differences that a glance would be well to notice.

We explore the initial conditions that lead to detached binary evolution of
massive pre-MS binaries and ask how large a fraction of the observed binary
systems may have been initially formed as low-mass protobinaries and later
undergone a significant accretion phase while remaining detached. We develop a
family of analytic models to describe the orbital separation, $a$, and mass
ratio, $q$, evolution. For a given mass accretion rate onto the binary system,
we define a recipe for distributing this mass between the two components. For
this we introduce a parameter $\eta$, such that
$\frac{\dot{M}_2}{\dot{M}_1}=q^\eta$ at any time, to determine the binary mass
ratio evolution. Depending on the choice of $\eta$, any type of mass ratio
evolution is possible. Furthermore, we use MESA, a detailed stellar structure
code, to calculate an extensive grid of binary sequences where a protobinary
undergoes accretion, and we identify the initial conditions that separates
detached from non-detached pre-MS binary evolution. A value of $\eta$ around 2
allows accretion growth in detached systems to form close massive binaries on
the Zero Age Main-Sequence with minimum orbital periods down to about 1.2 days
for $M_{\rm 1, ZAMS}=20-30M_{\odot}$ twin-binaries. $\eta=2$ can also reproduce
the observed population of binary systems with primary stars above
$6M_{\odot}$. The whole observed range of massive close binaries can form via
accretion growth in detached systems, making the binary formation channel of
accretion growth a strong contender to explain the formation of massive close
binaries, including progenitors of coalescing binary black holes.

The Sunyaev-Zel'dovich (SZ) effect has long been identified as one of the
most important secondary effects of the Cosmic Microwave Background (CMB). On
the one hand, it is a potentially very powerful cosmological probe providing us
with additional constraints and on the other hand it represents the major
source of secondary fluctuations at small angular scales (l > 1000). We
investigate the effects of the SZ modelling in the determination of the
cosmological parameters. We explore the consequences of the SZ power spectrum
computation by comparing three increasingly complex modelling, from a fixed
template with an amplitude factor to a calculation including the full
cosmological parameter dependency. We also examine the dependency of the
cosmological parameter estimation on the intra-cluster gas description used to
calculate the SZ spectrum. We show that methods assuming an SZ template bias
the cosmological parameters (by up to 2 sigmas on sigma_8) when the cosmology
used in the template deviates from the reference one. A joint CMB-SZ analysis
with a full cosmological dependency of the SZ spectrum does not suffer from
such biases and moreover improves the confidence intervals of sigma_8 and
Omega_{dm}h^2 (2.5 and 2 times respectively) with respect to a pure CMB
analysis. However, the latter method is quite sensitive to the intra-cluster
gas parameters and hence requires extra information on the clusters to
alleviate the induced biases.

We study the possibility of experimental verification of the spin=2 nature of
the Kaluza-Klein (KK) graviton which is predicted to exist in the
extra-dimensional Randal-Sundrum (RS) warped models. The couplings of these
gravitons to the particles located on or near the TeV brane is the strongest as
the overlap integral of their profiles in the extra-dimension is large. Among
them are unphysical Higgses ($W^{\pm}_L$ and $Z_L$) and KK excitations of the
Standard Model (SM) gauge bosons. We consider the possibility to confirm the
spin-2 nature of the first KK mode of the warped graviton ($G_1$) based on the
angular distribution of the Z bozon in the graviton rest frame in the gg$\to
G_1 \to W^{KK} (Z^{KK}) W (Z)\to WWZ$, gg$\to G_1\to ZZ$ and gg$\to G_1 \to
Z^{KK} Z\to ZZH$ decay channels. Using Wigner D-matrix properties, we derive
the relationship between the graviton spin, signal angular distribution peak
value, and other theoretically calculable quantities. We then study the LHC
signals for these decay modes and find that with 1000 fb$^{-1}$ of data, spin
of the RS graviton up to $\sim$ 2 TeV may be confirmed in the $pp \to W^{KK}
(Z^{KK}) W (Z) \to WWZ \to$ 3 leptons + jet + $\slashed{E}_T$ and $pp \to ZZ
\to$ 4 leptons decay modes.

Testing deviations from the $\Lambda$CDM model using the Cosmic Microwave
Background (CMB) power spectra requires a pristine understanding of
instrumental systematics. In this work we discuss the properties of a new
observable ${\cal R}^{TE}_{\ell}$, the correlation coefficient of temperature
and E modes. We find that this observable is mostly unaffected by systematics
introducing multiplicative biases such as errors in calibration, polarisation
efficiency, beam and transfer function measurements. We discuss the dependency
of this observable on the cosmological model and derive its statistical
properties. We then compute the T-E correlation coefficients of Planck legacy
data and compare them with expectations from the Planck best-fit $\Lambda$CDM
and foreground model.

Convolutional nets have been shown to achieve state-of-the-art accuracy in
many biomedical image analysis tasks. Many tasks within biomedical analysis
domain involve analyzing volumetric (3D) data acquired by CT, MRI and
Microscopy acquisition methods. To deploy convolutional nets in practical
working systems, it is important to solve the efficient inference problem.
Namely, one should be able to apply an already-trained convolutional network to
many large images using limited computational resources. In this paper we
present PZnet, a CPU-only engine that can be used to perform inference for a
variety of 3D convolutional net architectures. PZNet outperforms MKL-based CPU
implementations of PyTorch and Tensorflow by more than 3.5x for the popular
U-net architecture. Moreover, for 3D convolutions with low featuremap numbers,
cloud CPU inference with PZnet outperfroms cloud GPU inference in terms of cost
efficiency.

Configuration-Interaction (CI) models are approximations to the electronic
Schr\"odinger equation which are widely used for numerical electronic structure
calculations in quantum chemistry. Based on our recent closed-form asymptotic
results for the full atomic Schr\"odinger equation in the limit of fixed
electron number and large nuclear charge, we introduce a class of CI models for
atoms which reproduce, at fixed finite model dimension, the correct
Schr\"odinger eigenvalues and eigenstates in this limit.
We solve exactly the ensuing minimal model for the second period atoms, Li to
Ne. The energy levels and eigenstates are in remarkably good agreement with
experimental data (comparable to that of much larger scale numerical
simulations in the literature), and facilitate a mathematical understanding of
various spectral, chemical and physical properties of small atoms.

The cap doesn't stay closed!
I've used and loved NATHAN water bottles for years, I probably owned 5 or 6. I ordered this smaller size to use at the gym, but the cap seemed to pop off for no reason. I ordered a replacement, which seemed better at first, but the same happened after only 2 weeks of usage - resulting in water leaking into the seats of my car. Really upset the quality has become so terrible. Onto the next brand.

Quantum probes are atomic-sized devices mapping information of their
environment to quantum mechanical states. By improving measurements and at the
same time minimizing perturbation of the environment, they form a central asset
for quantum technologies. We realize spin-based quantum probes by immersing
individual Cs atoms into an ultracold Rb bath. Controlling inelastic
spin-exchange processes between probe and bath allows mapping motional and
thermal information onto quantum-spin states. We show that the steady-state
spin-population is well suited for absolute thermometry, reducing temperature
measurements to detection of quantum spin distributions. Moreover, we find that
the information gain per inelastic collision can be maximized by accessing the
nonequilibrium spin dynamic. The sensitivity of nonequilibrium quantum probing
effectively beats the steady-state Cram\'er Rao limit of quantum probing by
almost an order of magnitude, while reducing the perturbation of the bath to
only three quanta of angular momentum. Our work paves the way for local probing
of quantum systems at the Heisenberg limit, and moreover for optimizing

I think their work is excellent. Great stuff!
To the awful trolls on this site, do you not have anything better to do than to say negative things to some fellow Canadians who are brave enough to start their own business and do great work? Why don't you focus your energy on trying to be a better person. By the way, I'm a caucasian male and I'm happy as heck for these entrepreneurs. Don't listen to these folks ladies. Keep doing what you're doing!

We present maps of the ionized gas flux distributions, excitation,
star-formation rate SFR, surface mass density $\Sigma_{H+}$, and obtain total
values of SFR and ionized gas masses {\it M} for 62 Active Galactic Nuclei
(AGN) observed with SDSS-IV MaNGA and compare them with those of a control
sample of 112 non-active galaxies. The most luminous AGN -- with
$L(\rm{[OIII]}\lambda 5007) \ge 3.8\times 10^{40}\,\mbox{erg}\,\mbox{s}^{-1}$,
and those hosted by earlier-type galaxies are dominated by Seyfert excitation
within 0.2 effective radius $R_e$ from the nucleus, surrounded by LINER
excitation or transition regions, while the less luminous and hosted by
later-type galaxies show equally frequent LINER and Seyfert excitation within
$0.2\,R_e$. The extent $R$ of the region ionized by the AGN follows the
relation $R\propto\,L(\rm{[OIII]})^{0.5}$ -- as in the case of the Broad-Line
Region. The SFR distribution over the region ionized by hot stars is similar
for AGN and controls, while the integrated SFR -- in the range
$10^{-3}-10$\,M$_\odot$\,yr$^{-1}$ is also similar for the late-type
sub-sample, but higher in the AGN for 75\% of the early-type sub-sample. We
thus conclude that there is no signature of AGN quenching star formation in the
body of the galaxy in our sample. We also find that 66\% of the AGN have higher
ionized gas masses $M$ than the controls -- in the range
10$^5-3\times10^7$\,M$_\odot$ -- while 75\% of the AGN have higher
$\Sigma_{H+}$ within $0.2\,R_e$ than the control galaxies.

For the modern world where data is becoming one of the most valuable assets,
robust data privacy policies rooted in the fundamental infrastructure of
networks and applications are becoming an even bigger necessity to secure
sensitive user data. In due course with the ever-evolving nature of newer
statistical techniques infringing user privacy, machine learning models with
algorithms built with respect for user privacy can offer a dynamically adaptive
solution to preserve user privacy against the exponentially increasing
multidimensional relationships that datasets create. Using these privacy aware
ML Models at the core of a Federated Learning Ecosystem can enable the entire
network to learn from data in a decentralized manner. By harnessing the
ever-increasing computational power of mobile devices, increasing network
reliability and IoT devices revolutionizing the smart devices industry, and
combining it with a secure and scalable, global learning session backed by a
blockchain network with the ability to ensure on-device privacy, we allow any
Internet enabled device to participate and contribute data to a global privacy
preserving, data sharing network with blockchain technology even allowing the
network to reward quality work. This network architecture can also be built on
top of existing blockchain networks like Ethereum and Hyperledger, this lets
even small startups build enterprise ready decentralized solutions allowing
anyone to learn from data across different departments of a company, all the
way to thousands of devices participating in a global synchronized learning
network.

Time-frequency representations such as the spectrogram are commonly used to
analyze signals having a time-varying distribution of spectral energy, but the
spectrogram is constrained by an unfortunate tradeoff between resolution in
time and frequency. A method of achieving high-resolution spectral
representations has been independently introduced by several parties. The
technique has been variously named reassignment and remapping, but while the
implementations have differed in details, they are all based on the same
theoretical and mathematical foundation. In this work, we present a brief
history of work on the method we will call the method of time-frequency
reassignment, and present a unified mathematical description of the technique
and its derivation. We will focus on the development of time-frequency
reassignment in the context of the spectrogram, and conclude with a discussion
of some current applications of the reassigned spectrogram.

What is it about drug addiction that so draws first-time filmmakers to offer their own take on the subject? This subject has been done to death. Drug abuse is bad. We get it. Drug addiction is painful to watch. We get that too. But the bleak subject matter doesn't give the filmmaker license to make a sloppy film. Every film need not be Hitchcockian masterpiece of cinematic excellence, or use Orson Wellesian deep focus, but it's still a narrative movie. Verite does not mean pseudo-documentary. Even consumer mini-DV cameras are capable of producing white whites and black blacks, and this filmmaker is just being lazy by shooting no contrast scenes with existing lighting: the subject is bleak enough without artificially forcing it with sloppy cinematography. And even documentary films have a sound mix. Vera Farmiga is very talented, given the right material, but the director obviously over-directed her and sucked all the life out of her performance. Addicts may live in a fog, but they still have emotions, but none of these characters seem to exist off-screen. The supporting players merely delivered their lines without creating real people. Sorry to be so harsh, Debra, but some things are true whether want to believe them or not. I'm sure your next film will be better -- but please, not another drug movie. :)

I saw this movie on Thursdays night after having a really boring day. I had no expectations, those I had were rather negative. Being that the only movie I've ever watched Jimmy in is the American version of Taxi with Queen Latifah(?)...don't ask why! But seriously..this movie is so cute! Drew Barrymore is always sweet, but I almost fell in love with Fallon's character. Why can't I meet a cute nerd like that. :) Movies like that are excellent. Simple, sweet and necessary. Sunday on a Thursdays. I'm not even a sports fan, but it's something about American movies with baseball that fascinates me. Probably the fact that we don't have that sport here in Norway.<br /><br />(My first comment ever.) Haha

We present a fully relativistic calculation of the bremsstrahlung emitted by
twisted electrons propagating in the field of bare heavy nuclei. The
electron-nucleus interaction is accounted for to all orders in the nuclear
binding strength parameter $\alpha Z$, thus allowing us to investigate the
bremsstrahlung in a strong field, where the effects of the "twistedness" are
expected to be most pronounced. To explore these effects, we study the angular
and polarization properties of the photons emitted in course of the inelastic
twisted electrons scattering by the gold target. The influence of the kinematic
parameters of the incident electrons on the double-differential cross section
and the degree of the linear polarization is also discussed.

Be patient charging the battery-It takes time, and a lot of it.
Lots of features. I have used a Garmin GPS for many years of traveling. My old Garmin would charge in a couple hours connected to my computer via the USB port. When I got this one, I charged it for a couple hours and basically had no charge. Just enough to get the downloads from the Garmin website. Once unplugged, it would die within a minute. Contacted Amazon and was going to send it back, but decided to let it charge overnight. The next day I could see it had a 1/4 charge. Decided to just let it keep charging all day into the next day. BOTTOM LINE, THIS GARMIN WILL CHARGE, BUT VERY, VERY SLOWLY! GIVE IT UP TO TWO DAYS AND MAKE SURE YOUR COMPUTER STAYS ON OR PLUG IT INTO A CONSTANT POWER SOURCE AND IT SHOULD CHARGE. BE PATIENT OR BUY SOMETHING DIFFERENT. Hope this helps

Anomalous resistive peaks below the superconducting transition temperature in
heavily boron doped nanocrystalline diamond films could have potential
application in switching devices, however the exact origin is still under
study. We establish a temperature dependence of this resistive phase similar to
what has been reported for in Josephson junction arrays and other granular
superconductors where the charge duel of the Berezinskii-Kosterlitz-Thouless
(BKT) transition has been observed. Non-linear magnetoresistance with a
temperature dependent peak feature below the critical field are also presented.
Pronounced temperature dependent hysteresis in the current voltage sweeps at
temperatures below the determined BKT critical point are related to pinning of
charge defects. It is shown that these collective features allude to a
Charge-BKT transition between charge and anti-charge analogues.

Malfunctioning 3 beep increments
Purchased in January, now 2 months later it is beeping in increments of 3 which is a malfunction error. Tried turning it off to see if it resets (several times) but it ultimately reverts to 3 beep malfunction error. Returning for replacement. Din’t Know how many stars it deserves but for now 1 star due to defect.

Using archival {\it Chandra} observations with a total exposure of 510 ks, we
present an updated catalog of point sources for Globular Cluster 47 Tucanae.
Our study covers an area of $\sim 176.7$ arcmin$^{2}$ (i.e., with
$R\lesssim7.5\arcmin$) with 537 X-ray sources. We show that the surface density
distribution of X-ray sources in 47 Tuc is highly peaked in cluster center,
rapidly decreases at intermediate radii, and finally rises again at larger
radii, with two distribution dips at $R\sim 100\arcsec$ and $R\sim 170\arcsec$
for the faint ($L_{X}\lesssim 5.0\times 10^{30} {\rm\ erg\,s^{-1}}$) and bright
($L_{X}\gtrsim 5.0\times 10^{30} {\rm\ erg\,s^{-1}}$) groups of X-ray sources,
separately. These distribution features are similar to those of Blue Straggler
Stars (BSS), where the distribution dip is located at $R\sim 200\arcsec$
\citep{ferraro2004}. By fitting the radial distribution of each group of
sources with a "generalized King model", we estimated an average mass of
$1.51\pm0.17\ M_{\odot}$, $1.44\pm0.15\ M_{\odot}$ and $1.16\pm0.06\ M_{\odot}$
for the BSS, bright and faint X-ray sources, respectively. These results are
consistent with the mass segregation effect of heavy objects in GCs, where more
massive objects drop to the cluster center faster and their distribution dip
propagates outward further. Besides, the peculiar distribution profiles of
X-ray sources and BSS are also consistent with the mass segregation model of
binaries in GCs, which suggests that in addition to the dynamical formation
channel, primordial binaries are also a significant contributor to the X-ray
source population in GCs.

The spin-1/2 Heisenberg antiferromagnet on the distorted honeycomb (DHC)
lattice is studied by means of the tensor renormalization group method. It is
unveiled that the system has a quantum phase transition of second-order between
the gapped quantum dimer phase and a collinear Neel phase at the critical point
of coupling ratio \alpha_{c} = 0.54, where the quantum critical exponents \nu =
0.69(2) and \gamma = 1.363(8) are obtained. The quantum criticality is found to
fall into the O(3) universality class. A ground-state phase diagram in the
field-coupling ratio plane is proposed, where the phases such as the dimer,
semi-classical Neel, and polarized phases are identified. A link between the
present spin system to the boson Hubbard model on the DHC lattice is also
discussed.

The primordial gravitational waves (\textbf{PGW}) have been generated by
inflationary amplification of the primordial (quantum) fluctuations. It is true
that they have not been recorded directly so far, but their spectrum can help a
lot in solving the basic puzzles of the early universe as Inflation (high)
energy scale. In the present work, we give a straightforward method to
calculate the spectral energy density (\textbf{SED}) of the relic gravitons
different from that used in e.g. \cite{ mirza04,Latham 2005, Yuki 2006}. In our
approach, the evolution equations are in terms of the scale factor (instead of
conformal time) through the Lagrange formalism (instead of the transfer
function). The presence of the Hubble parameter allows to calculate the power
spectrum in the different dynamical regimes.

This paper investigates a new class of carrier-sense multiple access (CSMA)
protocols that employ deep reinforcement learning (DRL) techniques for
heterogeneous wireless networking, referred to as carrier-sense
deep-reinforcement learning multiple access (CS-DLMA). Existing CSMA protocols,
such as the medium access control (MAC) of WiFi, are designed for a homogeneous
network environment in which all nodes adopt the same protocol. Such protocols
suffer from severe performance degradation in a heterogeneous environment where
there are nodes adopting other MAC protocols. This paper shows that DRL
techniques can be used to design efficient MAC protocols for heterogeneous
networking. In particular, in a heterogeneous environment with nodes adopting
different MAC protocols (e.g., CS-DLMA, TDMA, and ALOHA), a CS-DLMA node can
learn to maximize the sum throughput of all nodes. Furthermore, compared with
WiFi's CSMA, CS-DLMA can achieve both higher sum throughput and individual
throughputs when coexisting with other MAC protocols. Last but not least, a
salient feature of CS-DLMA is that it does not need to know the operating
mechanisms of the co-existing MACs. Neither does it need to know the number of
nodes using these other MACs.

We introduce matrix coupled (local and nonlocal) dispersionless equations,
construct wide classes of explicit multipole solutions, give explicit
expressions for the corresponding Darboux and wave matrix valued functions and
consider their asymptotics in some interesting cases. We consider the scalar
cases of coupled, complex coupled and nonlocal dispersionless equations as
well.

We study invariant functions on the reductions mod p^n of p-divisible groups.
The proof of the main result, which applies to one-dimensional groups, combines
results of Tate with van der Put's solution of his p-adic Corona problem. For
higher dimensional groups a generalization of the p-adic Corona problem would
have to be solved.

Many types of cells can sense external ligand concentrations with
cell-surface receptors at extremely high accuracy. Interestingly, ligand-bound
receptors are often internalized, a process also known as receptor-mediated
endocytosis. While internalization is involved in a vast number of important
functions for the life of a cell, it was recently also suggested to increase
the accuracy of sensing ligand as the overcounting of the same ligand molecules
is reduced. Here we show, by extending simple ligand-receptor models to
out-of-equilibrium thermodynamics, that internalization increases the accuracy
with which cells can measure ligand concentrations in the external environment.
Comparison with experimental rates of real receptors demonstrates that our
model has indeed biological significance.

Bizarre horror movie filled with famous faces but stolen by Cristina Raines (later of TV's "Flamingo Road") as a pretty but somewhat unstable model with a gummy smile who is slated to pay for her attempted suicides by guarding the Gateway to Hell! The scenes with Raines modeling are very well captured, the mood music is perfect, Deborah Raffin is charming as Cristina's pal, but when Raines moves into a creepy Brooklyn Heights brownstone (inhabited by a blind priest on the top floor), things really start cooking. The neighbors, including a fantastically wicked Burgess Meredith and kinky couple Sylvia Miles & Beverly D'Angelo, are a diabolical lot, and Eli Wallach is great fun as a wily police detective. The movie is nearly a cross-pollination of "Rosemary's Baby" and "The Exorcist"--but what a combination! Based on the best-seller by Jeffrey Konvitz, "The Sentinel" is entertainingly spooky, full of shocks brought off well by director Michael Winner, who mounts a thoughtfully downbeat ending with skill. ***1/2 from ****

The bounded rationality plays a vital role in the collective behavior of the
evacuation process. Also investigating human behavior in such an extreme
situation is a continuing concern within social psychology. In this paper, we
construct a cellular automaton (CA) model for the escape dynamics, and the
bounded rational behavior induced by heterogeneous information is introduced.
The non-trivial behavior shows in the replicator dynamics method with mean
field approximation, where people's perception of the distribution of
population and velocity is reduced to an average value in a certain direction.
Analyzing the escape efficiency shows that under the premise of rationality,
the bounded rational strategy can get higher performance. Interestingly, a
quantifiable meta-stable state appears in the escape process, and the escape
time is power-law dependent on system size.

We present calculations of the thermal and electric linear response in
graphene, including disorder in the self-consistent t-matrix approximation. For
strong impurity scattering, near the unitary limit, the formation of a band of
impurity states near the Fermi level leads to that Mott's relation holds at low
temperature. For higher temperatures, there are strong deviations due to the
linear density of states. The low-temperature thermopower is proportional to
the inverse of the impurity potential and the inverse of the impurity density.
Information about impurity scattering in graphene can be extracted from the
thermopower, either measured directly, or extracted via Mott's relation from
the electron-density dependence of the electric conductivity.

As the size and complexity of models and datasets grow, so does the need for
communication-efficient variants of stochastic gradient descent that can be
deployed to perform parallel model training. One popular
communication-compression method for data-parallel SGD is QSGD (Alistarh et
al., 2017), which quantizes and encodes gradients to reduce communication
costs. The baseline variant of QSGD provides strong theoretical guarantees,
however, for practical purposes, the authors proposed a heuristic variant which
we call QSGDinf, which demonstrated impressive empirical gains for distributed
training of large neural networks. In this paper, we build on this work to
propose a new gradient quantization scheme, and show that it has both stronger
theoretical guarantees than QSGD, and matches and exceeds the empirical
performance of the QSGDinf heuristic and of other compression methods.

Solving general high-dimensional partial differential equations (PDE) is a
long-standing challenge in numerical mathematics. In this paper, we propose a
novel approach to solve high-dimensional linear and nonlinear PDEs defined on
arbitrary domains by leveraging their weak formulations. We convert the problem
of finding the weak solution of PDEs into an operator norm minimization problem
induced from the weak formulation. The weak solution and the test function in
the weak formulation are then parameterized as the primal and adversarial
networks respectively, which are alternately updated to approximate the optimal
network parameter setting. Our approach, termed as the weak adversarial network
(WAN), is fast, stable, and completely mesh-free, which is particularly
suitable for high-dimensional PDEs defined on irregular domains where the
classical numerical methods based on finite differences and finite elements
suffer the issues of slow computation, instability and the curse of
dimensionality. We apply our method to a variety of test problems with
high-dimensional PDEs to demonstrate its promising performance.

"FULL HOUSE," in my opinion, is an absolute ABC classic! I'm not sure if I've never seen every episode, but I still enjoyed it. One of my favorite episodes is where Jesse (John Stamos) and Rebecca (Lori Loughlin) get married. If you want to know how what made it so funny, you'd have to have seen it for yourself. It was a two-parter, so you'd have to have seen both parts. Another one of my favorite episodes is where Jesse, Stephanie (Jodie Sweetin), and Michelle (Mary Kate & Ashley Olsen) get locked in a gas station on Michelle's birthday. You'd also have to have seen it for yourself if you want to know how and why that happened. I have many other ones that I like, too. Everyone always gave a good performance, the production design was spectacular, the costumes were well-designed, and the writing was always very strong. In conclusion, even though it can be seen in syndication now, I strongly recommend you catch it just in case it goes off the air for good.

We derive analytically the full distribution of the ground-state energy of
$K$ non-interacting fermions in a disordered environment, modelled by a
Hamiltonian whose spectrum consists of $N$ i.i.d.~random energy levels with
distribution $p(\varepsilon)$ (with $\varepsilon \geq 0$), in the same spirit
as the `Random Energy Model'. We show that for each fixed $K$, the distribution
$P_{K,N}(E_0)$ of the ground-state energy $E_0$ has a universal scaling form in
the limit of large $N$. We compute this universal scaling function and show
that it depends only on $K$ and the exponent $\alpha$ characterizing the small
$\varepsilon$ behaviour of $p(\varepsilon) \sim \varepsilon^\alpha$. We
compared the analytical predictions with results from numerical simulations.
For this purpose we employed a sophisticated importance-sampling algorithm that
allowed us to obtain the distributions over a large range of the support down
to probabilities as small as $10^{-160}$. We found asymptotically a very good
agreement between analytical predictions and numerical results.

The dynamical stability of dark solitons in dipolar Bose-Einstein condensates
is studied. For standard short-range interacting condensates dark solitons are
unstable against transverse excitations in two and three dimensions. On the
contrary, due to its non local character, the dipolar interaction allows for
stable 3D stationary dark solitons, opening a qualitatively novel scenario in
nonlinear atom optics. We discuss in detail the conditions to achieve this
stability, which demand the use of an additional optical lattice, and the
stability regimes.

The synthetic biopolymeric gels demand a great interest as bio-materials to
mimic many biological scaffolding structures, which can contribute to a better
understanding of the cytoskeleton-like structural building blocks and soft
nanotechnology. In particular semiflexible F-actin and vimentin intermediate
filaments (IF) form complex networks, and are key regulators of cellular
stiffness. While the mechanics of F-actin networks or IF have already been
characterised, the interaction between this two networks is largely unknown.
Experimental studies using large deformations rheology show that
co-polymerisation of F-actin and IF can produce composite networks either
stronger or weaker than pure F-actin networks. We theoretically verify these
effects developing a model into the framework of nonlinear continuum mechanics,
in which we define a free energy functional considering the role of the
entropic-elastic for semiflexible networks with transient crosslinks and also
an energetic term to describe the interaction parameter which allows the
coupling among the two networks. We validate the theoretical model with
measurements performed performed by Jensen et al. on large deformations
rheological experiments with different concentrations of actin and vimentin

OK I went to this website before I watched this movie, read the comments, got pumped, - cause they where all pretty good for a B-flick - watched it and was completely disappointed. The main characters wannabe lone rebel straight out of the mid-west act was sickening to the stomach, and don't even get me started on the two cops, I mean there's a bloody door right there in plain view, check it out! The plot was completely predictable, the editing was rather limited, I swear the editor was even dozing off near the end when he was cutting this movie, and the direction was clouded by bad cinematography. Now please don't get me wrong, I love B-flicks, some are really good.<br /><br />Want to watch a good B rated flick???<br /><br />Dave recommends<br /><br />" High Tension "<br /><br />http://imdb.com/title/tt0338095/

This paper provides an outline of the algorithms submitted for the WSDM Cup
2019 Spotify Sequential Skip Prediction Challenge (team name: mimbres). In the
challenge, complete information including acoustic features and user
interaction logs for the first half of a listening session is provided. Our
goal is to predict whether the individual tracks in the second half of the
session will be skipped or not, only given acoustic features. We proposed two
different kinds of algorithms that were based on metric learning and sequence
learning. The experimental results showed that the sequence learning approach
performed significantly better than the metric learning approach. Moreover, we
conducted additional experiments to find that significant performance gain can
be achieved using complete user log information.

The compound, LaMn2Ge2, crystallizing in ThCr2Si2-type tetragonal crystal
structure, has been known to undergo ferromagnetic order below (T_C=) 326 K. In
this article, we report the magnetic behavior of nanocrystalline form of this
compound, obtained by high-energy ball-milling. T_C of this compound is reduced
maginally for the nanoform, whereas there is a significant reduction of the
magnitude of the saturation magnetic moment with increasing milling time. The
coercive field however increases with decreasing particle size. Thus, this work
provides a route to tune these parameters by reducing the particle size in this
ternary family.

I'd like to start by saying I would not go see this movie again if they were giving out popcorn made of solid gold and the ticket granted me eternal life. This movie was terrible. I can't give this it a truly honest rating because there are no negative stars. The acting is absolutely terrible. This movie is a travesty, based on the classic, "The Most Dangerous Game". If you really want to torture yourself for 90 minutes rent something like Gigli. At least J-Lo provides some better scenery, Ben should pacify the ladies viewing it. I'm not upset about the $7 I paid to see the move, I'd just like the 90 minutes of my life back.<br /><br />"Can you give me my time back!?!" Samuel L. Jackson, Changing Lanes

Spitzer IRAC observations of two fields in the XUV-disk of M83 have been
recently obtained,3R_{HII} away from the center of the galaxy (R_{HII)=6.6
kpc).GALEX UV images have shown the two fields to host in-situ recent star
formation.The IRAC images are used in conjunction with GALEX data and new HI
imaging from THINGS to constrain stellar masses and ages of the UV clumps in
the fields,and to relate the local recent star formation to the reservoir of
available gas. multi wavelength photometry in the UV and mid-IR bands of 136 UV
clumps(spatial resolution >220pc) identified in the two target fields, together
with model fitting of the stellar UV-MIR SED,suggest that the clumps cover a
range of ages between a few Myr and >1Gyr with a median value around
<100Myr,and have masses in the range 10^3-3*10^6M, with a peak ~10^4.7M.The
range of observed ages,for which only a small fraction of the mass in stars
appears to have formed in the past ~10Myr, agrees with the dearth of Ha
emission observed in these outer fiel ds. At the location of our IRAC fields,
the HI map shows localized enhancement and clumping of atomic gas. A comparison
of the observed star formation with the gas reservoir shows that the UV clumps
follow the Schmidt--Kennicutt scaling law of star formation,and that star
formation is occurring in regions with gas dens ities at approximately (within
a factor of a few) the critical density value de -rived according to the Toomre
Q gravitational stability criterion. The signifi cant 8 micron excess in
several of the clumps (16% of the total by number accou nting for ~67% of the 8
micron flux)) provides evidence for the existence of dust in these remote
fields, in agreement with results for other galaxies. Furt hermore, we observe
a relatively small excess of emission at 4.5 micron in the clumps...

In this paper we introduce a new approach to computing hidden features of
sampled vector fields. The basic idea is to convert the vector field data to a
graph structure and use tools designed for automatic, unsupervised analysis of
graphs. Using a few data sets we show that the collected features of the vector
fields are correlated with the dynamics known for analytic models which
generates the data. In particular the method may be useful in analysis of data
sets where the analytic model is poorly understood or not known.

Forecasting elections -- a challenging, high-stakes problem -- is the subject
of much uncertainty, subjectivity, and media scrutiny. To shed light on this
process, we develop a method for forecasting elections from the perspective of
dynamical systems. Our model borrows ideas from epidemiology, and we use
polling data from United States elections to determine its parameters.
Surprisingly, our general model performs as well as popular forecasters for the
2012 and 2016 U.S. races for president, senators, and governors. Although
contagion and voting dynamics differ, our work suggests a valuable approach to
elucidate how elections are related across states. It also illustrates the
effect of accounting for uncertainty in different ways, provides an example of
data-driven forecasting using dynamical systems, and suggests avenues for
future research on political elections. We conclude with our forecasts for the
senatorial and gubernatorial races on 6~November 2018, which we posted on 5
November 2018.

The origin of the radio emission in Radio Quiet (RQ) quasars is not
established yet. Important hints can be provided by the spectral slope, and its
relation to other emission properties. We compiled the highest resolution 5 and
8.4 GHz VLA observations available of the RQ optically selected PG quasars at
z<0.5. We derive the 5-8.4 GHz spectral slope, alpha_R, for 25 of the complete
and well studied sample of 71 RQ PG quasars. We find a highly significant
correlation of alpha_R with L/L_Edd, where high L/L_Edd (>0.3) quasars have a
steep slope (alpha_R<-0.5), indicative of an optically thin synchrotron source.
In contrast, lower L/L_Edd (<0.3) quasars generally have a flat slope
(alpha_R>-0.5), indicative of a compact optically thick synchrotron source.
Flat alpha_R quasars also have a low Fe II/Hbeta line ratio, and a flat soft
X-ray slope. The 16 Radio Loud (RL) PGs do not follow the RQ quasar set of
correlations, and their alpha_R is set by M_BH, suggesting that the radio
emission mechanisms in RL and RQ quasars are different. A possible
interpretation is that high L/L_Edd RQ quasars produce a strong outflow and an
associated optically thin synchrotron emission. In lower L/L_Edd RQ quasars,
the strong outflow is missing, and only a compact optically thick radio source
remains, possibly associated with the accretion disk coronal emission. A
systematic study of RQ quasars at higher frequencies, and higher resolution,
can test whether a compact flat source indeed resides in the cores of all RQ
quasars, and allow the exploration of its relation with the coronal X-ray
emission.

This derivative erotic thriller remains watchable most of the way, mainly because a viewer is casually curious about how it will turn out, and because the director, Peter Hall, manages to stage a pretty hot (and quite bold) sex scene. But the finale, though unexpected, is preposterous, and the whole plotting (complete with childhood traumas and multiple-personality disorders) reveals itself to be unbearably cliched, especially as far as motivation is concerned.

X-ray surveys facilitate investigations of the environment of AGNs. Deep
Chandra observations revealed that the AGNs source surface density rises near
clusters of galaxies. The natural extension of these works is the measurement
of spatial clustering of AGNs around clusters and the investigation of relative
biasing between active galactic nuclei and galaxies near clusters.The major
aims of this work are to obtain a measurement of the correlation length of AGNs
around clusters and a measure of the averaged clustering properties of a
complete sample of AGNs in dense environments. We present the first measurement
of the soft X-ray cluster-AGN cross-correlation function in redshift space
using the data of the ROSAT-NEP survey. The survey covers 9x9 deg^2 around the
North Ecliptic Pole where 442 X-ray sources were detected and almost completely
spectroscopically identified. We detected a >3sigma significant clustering
signal on scales s<50 h70^-1 Mpc. We performed a classical maximum-likelihood
power-law fit to the data and obtained a correlation length s_0=8.7+1.2-0.3
h_70-1 Mpc and a slope gamma=1.7$^+0.2_-0.7 (1sigma errors). This is a strong
evidence that AGNs are good tracers of the large scale structure of the
Universe. Our data were compared to the results obtained by cross-correlating
X-ray clusters and galaxies. We observe, with a large uncertainty, that the
bias factor of AGN is similar to that of galaxies.

A predictive distribution over a sequence of $N+1$ events is said to be
"frequency mimicking" whenever the probability for the final event conditioned
on the outcome of the first $N$ events equals the relative frequency of
successes among them. Infinitely extendible exchangeable distributions that
universally inhere this property are known to have several annoying concomitant
properties. We motivate frequency mimicking assertions over a limited subdomain
in practical problems of finite inference, and we identify their computable
coherent implications. We provide some computed examples using reference
distributions, and we introduce computational software to generate any
specification. The software derives from an inversion of the finite form of the
exchangeability representation theorem. Three new theorems delineate the extent
of the usefulness of such distributions, and we show why it may not be
appropriate to extend the frequency mimicking assertions for a specified value
of $N$ to any arbitrary larger size of $N$. The constructive results identify
the source and structure of "adherent masses" in the limit of a sequence of
finitely additive distributions. Appendices develop a novel geometrical
representation of conditional probabilities which illuminate the analysis.

Steel Toes and Teeth keeps you hooked till the end.
A very easy read. I started late on a Friday and had to finish on Saturday. Jerry gives you a good feel for the characters and you genuinely care what happens to them. I also found myself trying to pick out clues as I read thinking ok this has to be important. I highly recommend this book I seldom find one I just have to keep going till I’m done but this is one. It would be interesting to have a series featuring this character on different assignments. Can’t wait for the next book regardless the subject!

Good fit, denim wash looks dirty
I usually order 14 or 16 in jeans and I got the 16. They fit well and a 14 would have been too small. The fabric is thin and has a good amount of stretch.The wash is kind of dirty-looking otherwise I would have rated it higher. I don't mind some sanding and fading but these will only be good for casual looks, not with heels as pictured.

A couple times a year, some “new report” makes the rounds on social media alerting us all to the fact that—ick, yuck, shudder—something or other has “more germs than a toilet seat.” This is apparently primo would-be-viral content, to judge by how often those headlines come up.
Ew, gross, right? You shudder, cringe, comment about hygiene practices … and then move on because what are you actually going to do about the fact that [the thing you can’t avoid touching] has cooties? Here’s what becomes clear after a few rounds of this: Every damn thing has more germs than a toilet seat—and one surprising reason may be that toilet seats actually aren’t that dirty, perhaps because people think they’re so dirty that they get cleaned a lot.
The dirtier-than-a-toilet-seat list includes cell phones, steering wheels, shopping carts, restaurant menus, and restaurant high chairs. It includes just about everything in the kitchen, starting with your sponges and cleaning cloths and going on to your cutting board and faucet. All of which are positively teeming with germs. Your clean laundry? Maybe not so clean.
In public, add on money, ATMs, elevator buttons, door handles, and … you know what? If a lot of people touch it, it is extremely dirty.
In short, guys, maybe this is not something to get so worked up about. Wash your hands, keep your possessions clean, and don’t click through to find out the shocking truth about TV remotes.

Lighting good, but only one alarm sound
The sunrise simulation portion is good. I have to have mine set to Level 10 (highest level) in order for it actually wake me up. The alarm itself is only a buzzer. There is no option for other sounds. This is a good, basic sunrise alarm clock. If you want more variety, I'd recommend Phillips' more expensive version. I had that one prior to having to purchase this one when I moved overseas.

We examine whether the accretion of dark matter onto neutron stars could ever
have any visible external effects. Captured dark matter which subsequently
annihilates will heat the neutron stars, although it seems the effect will be
too small to heat close neutron stars at an observable rate whilst those at the
galactic centre are obscured by dust. Non-annihilating dark matter would
accumulate at the centre of the neutron star. In a very dense region of dark
matter such as that which may be found at the centre of the galaxy, a neutron
star might accrete enough to cause it to collapse within a period of time less
than the age of the Universe. We calculate what value of the stable dark
matter-nucleon cross section would cause this to occur for a large range of
masses.

Mahalo to Ms. Leed for sharing. Aloha and peace to aunty Didi. More Alzheimer's research and funds have to be poured into this disease. On its current course and without a foreseeable cure this disease will bankrupt our healthcare system. Early onset Alzheimer's especially weighs heavily on family members and the medicare/medicaid system. Foster care, home care costs skyrocket for families personal finances. Cancer and heart disease have millions of dollars in research funding. So should Alzheimers and dementia.

The anomalous Nernst effect (ANE) - the generation of a transverse electric
voltage by a longitudinal heat current in conducting ferromagnets or
antiferromagnets - is an appealing approach for thermoelectric power generation
in spin caloritronics. The ANE in antiferromagnets is particularly convenient
for the fabrication of highly efficient and densely integrated thermopiles as
lateral configurations of thermoelectric modules increase the coverage of heat
source without suffering from the stray fields that are intrinsic to
ferromagnets. In this work, using first-principles calculations together with a
group theory analysis, we systematically investigate the spin order-dependent
ANE in noncollinear antiferromagnetic Mn-based antiperovskite nitrides
Mn$_{3}X$N ($X$ = Ga, Zn, Ag, and Ni). The ANE in Mn$_{3}X$N is forbidden by
symmetry in the R1 phase but amounts to its maximum value in the R3 phase.
Among all Mn$_{3}X$N compounds, Mn$_{3}$NiN presents the most significant
anomalous Nernst conductivity of 1.80 AK$^{-1}$m$^{-1}$ at 200 K, which can be
further enhanced if strain, electric, or magnetic fields are applied. The ANE
in Mn$_{3}$NiN, being one order of magnitude larger than that in the famous
Mn$_{3}$Sn, is the largest one discovered in antiferromagnets so far. The giant
ANE in Mn$_{3}$NiN originates from the sharp slope of the anomalous Hall
conductivity at the Fermi energy, which can be understood well from the Mott
relation. Our findings provide a novel host material for realizing
antiferromagnetic spin caloritronics which promises exciting applications in
energy conversion and information processing.

Graph refinement, or the task of obtaining subgraphs of interest from
over-complete graphs, can have many varied applications. In this work, we
extract trees or collection of sub-trees from image data by, first deriving a
graph-based representation of the volumetric data and then, posing the tree
extraction as a graph refinement task. We present two methods to perform graph
refinement. First, we use mean-field approximation (MFA) to approximate the
posterior density over the subgraphs from which the optimal subgraph of
interest can be estimated. Mean field networks (MFNs) are used for inference
based on the interpretation that iterations of MFA can be seen as feed-forward
operations in a neural network. This allows us to learn the model parameters
using gradient descent. Second, we present a supervised learning approach using
graph neural networks (GNNs) which can be seen as generalisations of MFNs.
Subgraphs are obtained by training a GNN-based graph refinement model to
directly predict edge probabilities. We discuss connections between the two
classes of methods and compare them for the task of extracting airways from 3D,
low-dose, chest CT data. We show that both the MFN and GNN models show
significant improvement when compared to one baseline method, that is similar
to a top performing method in the EXACT'09 Challenge, and a 3D U-Net based
airway segmentation model, in detecting more branches with fewer false
positives.

We investigate the impact of modified-gravity models on the Lyman-$\alpha$
power spectrum. Building a simple analytical modeling, based on a truncated
Zeldovich approximation, we estimate the intergalactic medium power spectrum
and the Lyman-$\alpha$ flux decrement power spectrum along the line of sight.
We recover the results of numerical simulations for $f(R)$-gravity models and
present new results for K-mouflage scenarios. We find that the shape of the
distortion due to the modified gravity depends on the model, through the
scale-dependence or not of their growth rate. This is more clearly seen in the
three-dimensional power spectrum than in the one-dimensional power spectrum,
where the line-of-sight integration smoothes the deviation. Whilst the
Lyman-$\alpha$ power spectrum does not provide competitive bounds for $f(R)$
theories, it could provide useful constraints for the K-mouflage models. Thus,
the efficiency of the Lyman-$\alpha$ power spectrum as a probe of
modified-gravity scenarios depends on the type of screening mechanism and the
related scale dependence it induces. The prospect of a full recovery of the
three-dimensional Lyman-$\alpha$ power spectrum from data would also lead to
stronger constraints and a better understanding of screening mechanisms.

Not the proper screws for 2018 CR-V
These screws are the wrong type for the 2018 Honda CR-V. They are machine type that require a bolt to fasten to. The CR-V uses self threading type. The quality does look pretty good for the price but I won't know how they last cause I can't use them.

Parity violation in gravity, if existed, could have important implications,
and it is meaningful to search and test the possible observational effects.
Chern-Simons modified gravity serves as a natural model for gravitational
parity-violations. Especially, considering extensions to Einstein-Hilbert
action up to second order curvature terms, it is known that theories of
gravitational parity-violation will reduce to the dynamical Chern-Simons
gravity. In this letter, we outline the theoretical principles of testing the
dynamical Chern-Simons gravity with orbiting gravity gradiometers, which could
be naturally incorporated into future satellite gravity missions. The secular
gravity gradient signals, due to the Mashhoon-Theiss (anomaly) effect, in
dynamical Chern-Simons gravity are worked out, which can improve the constraint
of the corresponding Chern-Simons length scale $\xi^{\frac{1}{4}}_{cs}$
obtained from such measurement scheme. For orbiting superconducting
gradiometers or gradiometers with optical readout, a bound
$\xi^{\frac{1}{4}}_{cs}\leq 10^6 \ km$ (or even better) could in principle be
obtained, which will be at least 2 orders of magnitude stronger than the
current one based on the observations from the GP-B mission and the LAGEOS I,
II satellites.

Comfy but you lose sleep space...
Bought a twin for my young son. Very comfy and easy to set-up. My issue is that the edges of the mattress collapse with pressure. This is my first memory foam bed so maybe that is the case with all such mattresses. But with a twin, it means you lose a large percentage of the actual sleep space. When I lay down with my son I can't go anywhere near the edge because I start to slide off or at best I'm on a slope... Back it goes...

Very Pretty Case - But stains from normal use
When I first got this otter box I loved it!!!! The color is feminine and I was very happy with it. After only about a week of normal use I noticed that the case absorbs stains just from sitting in my pocketbook and just from very gentle use the case got dirty and I've tried absolutely everything to clean it but the stains absorb and the case does not come clean. I'm so disappointed :( I expect much better quality from Otter box.

A unified treatment is given of some results of H. Donnelly-P. Li and L.
Schwartz concerning the behaviour of heat semigroups on open manifolds with
given compactifications, on one hand, and the relationship with the behaviour
at infinity of solutions of related stochastic differential equations on the
other. A principal tool is the use of certain covers of the manifold: which
also gives a non-explosion test. As a corollary we obtain known results about
the behaviour of Brownian motions on a complete Riemannian manifold with Ricci
curvature decaying at most quadratically in the distance function.

Black phosphorus (BP), a two-dimensional (2D) van der Waals layered material
composed of phosphorus atoms, has been one of the most actively studied 2D
materials in recent years due to its tunable energy band gap (tunable even to a
negative value) and its highly anisotropic electronic structure. Depending on
the sign of the band gap tuning parameter, few-layer BP can be in a gapped
insulator phase, gapless Dirac semimetal phase, or gapless semi-Dirac
transition point between the two phases. Using the fully anisotropic multiband
Boltzmann transport theory, we systematically study the dc conductivity of
few-layer BP as a function of the carrier density and temperature by varying
the band gap tuning parameter, and determine the characteristic density and
temperature dependence corresponding to each phase.

The scale and complexity of modern data sets and the limitations associated
with testing large numbers of hypotheses underline the need for feature
selection methods. Spectral techniques rank features according to their degree
of consistency with an underlying metric structure, but their current
graph-based formulation restricts their applicability to point features. We
extend spectral methods for feature selection to abstract simplicial complexes
and present a general framework which can be applied to 2-point and
higher-order features. Combinatorial Laplacian scores take into account the
topology spanned by the data and reduce to the ordinary Laplacian score in the
case of point features. We demonstrate the utility of spectral simplicial
methods for feature selection with several examples of application to the
analysis of gene expression and multi-modal genomic data. Our results provide a
unifying perspective on topological data analysis and manifold learning
approaches.

Phase-change materials (PCMs) can switch between different crystalline states
as a function of an external bias, offering a pronounced change of their
dielectric function. In order to take full advantage of these features for
active photonics and information storage, stand-alone PCMs are not sufficient,
since the phase transition requires strong pump fields. Here, we explore hybrid
metal-semiconductor core-shell nanoantennas loaded with PCMs, enabling a
drastic switch in scattering features as the load changes its phase. Large
scattering, beyond the limits of small resonant particles, is achieved by
spectrally matching different Mie resonances, while scattering cancellation and
cloaking is achieved with out-of-phase electric dipole oscillations in the PCM
shell and Ag core. We show that tuning the PCM crystallinity we can largely
vary total (~15 times) and forward (~100 times) scattering. Remarkably, a
substantial reconfiguration of the scattering pattern from Kerker (zero
backward) to antiKerker (almost zero forward) regimes with little change (~5%)
in crystallinity is predicted, which makes this structure promising
low-intensity nonlinear photonics.

You are comparing a one or two day temperature anomaly over a tiny portion of the arctic to a historical mean temp for the month of January? Just like when the majority of sea level buoys have shown a sea level DECREASE over most areas around Alaska when you claimed the opposite. You are all about spreading FAKE science
