We present a model of adaptive regulatory networks consisting of a simple
biologically-motivated rewiring procedure coupled to an elementary stability
criterion. The resulting networks exhibit a characteristic stationary
heavy-tailed degree distribution, show complex structural microdynamics and
self-organize to a dynamically critical state. We show analytically that the
observed criticality results from the formation and breaking of transient
feedback loops during the adaptive process.

Honey has been collected and used by humankind as both a food and medicine
for thousands of years. However, in the modern economy, honey has become
subject to mislabelling and adulteration making it the third most faked food
product in the world. The international scale of fraudulent honey has had both
economic and environmental ramifications. In this paper, we propose a novel
method of identifying fraudulent honey using machine learning augmented
microscopy.

Art,
Please tell me that you really don't intend to say that the rise of incidents like that described in the article is Canada's fault because we haven't adopted sufficiently xenophobic immigration, border-entry and aggressive deportation policies and practices to match those assumed to apply in the US (I say assumed because there are many appeals to the courts in the US regarding the new, post-election measures in question).

A longtime fan of Bette Midler, I must say her recorded live concerts are my favorites. Bette thrills us with her jokes and brings us to tears with her ballads. A literal rainbow of emotion and talent, Bette shows us her best from her solid repertoire, as well as new songs from the "Bette of Roses" album. Spanning generations of people she offers something for everyone. The one and only Divine Diva proves here that she is the most intensely talented performer around.

It doesn’t work
Extremely unhappy with this product. Absolutely ineffective and a total waste of $30. Do not buy this. I used it 2 times a day for three weeks on two cats that I had to feed separately. I ended up spending $200 at the vet with one pill that was effective.

I have seen many - possibly too many straight-to-video, no budget slasher films and have developed a taste for the "good ones", or the ones that are less sucky, as ridiculous as that sounds, hahaha. DR. CHOPPER, is what I kindly like to refer to as... absolute crap. Nothing about it is enjoyable - the acting sucks, the characters suck, the killer sucks, the gore is minimal... and sucks. It is about a group of college friends who drive out to a newly discovered family cabin, owned by the parents of one of the kids. It is meant to be a relaxing retreat, but little do they know that a deathly ill former plastic surgeon-gone bad, along with his two female assistants, search for usable tissue to save the doctor. His name is Dr. Chopper since he rides around on a motorcycle and of course, chops. This is just a terrible movie, not worthy of anyone's time. Enough said.

The assumption that the Universe, on sufficiently large scales, is
homogeneous and isotropic is crucial to our current understanding of cosmology.
In this paper we test if the observed galaxy distribution is actually
homogeneous on large scales. We have carried out a multifractal analysis of the
galaxy distribution in a volume limited subsample from the SDSS DR6. This
considers the scaling properties of different moments of galaxy number counts
in spheres of varying radius $r$ centered on galaxies. This analysis gives the
spectrum of generalized dimension $D_q(r)$, where $q >0$ quantifies the scaling
properties in overdense regions and $q<0$ in underdense regions. We expect
$D_q(r)=3$ for a homogeneous, random point distribution.
In our analysis we have determined $D_q(r)$ in the range $-4 \le q \le 4$ and
$7 \le r \le 98 h^{-1} {\rm Mpc}$. In addition to the SDSS data we have
analysed several random samples which are homogeneous by construction.
Simulated galaxy samples generated from dark matter N-body simulations and the
Millennium Run were also analysed. The SDSS data is considered to be
homogeneous if the measured $D_q$ is consistent with that of the random
samples. We find that the galaxy distribution becomes homogeneous at a
length-scale between 60 and $70 h^{-1} {\rm Mpc}$. The galaxy distribution, we
find, is homogeneous at length-scales greater than $70 h^{-1} {\rm Mpc}$. This
is consistent with earlier works which find the transition to homogeneity at
around $70 h^{-1} {\rm Mpc}$.

A one-dimensional and stationary reactor model is presented to describe the
catalytic conversion of a gaseous hydrocarbon fuel with air and steam to
synthesis gas by autothermal reforming (ATR) and catalytic partial oxidation
(CPO). The model defines two subsequent sections in the reactor, namely an
upstream oxidation section, and a downstream reforming section. In the
oxidation section all of the oxygen is converted, with partial conversion of
the fuel. An empirical fuel utilization ratio is used to quantify which part of
the fuel is converted in the oxidation section as function of the relative
flows of air and steam. In the oxidation section, the gas temperature rapidly
increases toward the toptemperature at the intersection with the reforming
section. In this section the temperature decreases while the fuel is further
converted with water and CO2 as oxidant. For methane as fuel, simulation
results are presented and compared with experiments. For multicomponent fuels
such as natural gas and naphtha, it is described how the two-section model can
be applied.

In this paper we present results of our calculations of the non-collinear
spin density distribution in the systems with frustrated triangular magnetic
structure (Mn-based antiperovskite compounds, Mn_{3}AN (A=Ga, Zn)) in the
ground state and under external mechanical strain. We show that the spin
density in the (111)-plane of the unit cell forms a "domain" structure around
each atomic site but it has a more complex structure than the uniform
distribution of the rigid spin model, i.e. Mn atoms in the (111)-plane form
non-uniform "spin clouds", with the shape and size of these "domains" being
function of strain. We show that both magnitude and direction of the spin
density change under compressive and tensile strains, and the orientation of
"spin domains" correlates with the reversal of the strain, i.e. switching
compressive to tensile strain (and vice versa) results in "reversal" of the
domains. We present analysis for the intra-atomic spin-exchange interaction and
the way it affects the spin density distribution. In particular, we show that
the spin density inside the atomic sphere in the system under mechanical stress
depends on the degree of localization of electronic states.

The aim of this work is to understand some of the asymptotic properties of
sequences of lattices in a fixed locally compact group. In particular we will
study the asymptotic growth of the Betti numbers of the lattices renormalized
by the covolume and the rank gradient, the minimal number of generators also
renormalized by the covolume. For doing so we will consider the ultraproduct of
the sequence of actions of the locally compact group on the coset spaces and we
will show how the properties of one of its cross sections are related to the
asymptotic properties of the lattices.

Topological representations are rapidly becoming a popular way to capture and
encode higher-order interactions in complex systems. They have found
applications in disciplines as different as cancer genomics, brain function,
and computational social science, in representing both descriptive features of
data and inference models. While intense research has focused on the
connectivity and homological features of topological representations,
surprisingly scarce attention has been given to the investigation of the
community structures of simplicial complexes. To this end, we adopt recent
advances in symbolic embeddings to compute and visualize the community
structures of simplicial complexes. We first investigate the stability
properties of embedding obtained for synthetic simplicial complexes to the
presence of higher order interactions. We then focus on complexes arising from
social and brain functional data and show how higher order interactions can be
leveraged to improve clustering detection and assess the effect of higher order
interaction on individual nodes. We conclude delineating limitations and
directions for extension of this work.

We describe two algorithms for finding representatives of the nilpotent
orbits of a theta-group. The algorithms have been implemented in the computer
algebra system GAP (inside the package SLA). We comment on their performance.
We apply the algorithms to study the nilpotent orbits of theta-groups, where
theta is an N-regular automorphism of a simple Lie algebra of exceptional type.

This survey of topological cyclic homology is a chapter in the Handbook on
Homotopy Theory. We give a brief introduction to topological cyclic homology
and the cyclotomic trace map following Nikolaus-Scholze, followed by a proof of
B\"okstedt periodicity that closely resembles B\"okstedt's original unpublished
proof. We explain the extension of B\"{o}kstedt periodicity by
Bhatt-Morrow-Scholze from perfect fields to perfectoid rings and use this to
give a purely p-adic proof of Bott periodicity. Finally, we evaluate the
cofiber of the assembly map in p-adic topological cyclic homology for the
cyclic group of order p and a perfectoid ring of coefficients.

Precision infrared photometry from Spitzer has enabled the first direct
studies of light from extrasolar planets, via observations at secondary eclipse
in transiting systems. Current Spitzer results include the first longitudinal
temperature map of an extrasolar planet, and the first spectra of their
atmospheres. Spitzer has also measured a temperature and precise radius for the
first transiting Neptune-sized exoplanet, and is beginning to make precise
transit timing measurements to infer the existence of unseen low mass planets.
The lack of stellar limb darkening in the infrared facilitates precise radius
and transit timing measurements of transiting planets. Warm Spitzer will be
capable of a precise radius measurement for Earth-sized planets transiting
nearby M-dwarfs, thereby constraining their bulk composition. It will continue
to measure thermal emission at secondary eclipse for transiting hot Jupiters,
and be able to distinguish between planets having broad band emission versus
absorption spectra. It will also be able to measure the orbital phase variation
of thermal emission for close-in planets, even non-transiting planets, and
these measurements will be of special interest for planets in eccentric orbits.
Warm Spitzer will be a significant complement to Kepler, particularly as
regards transit timing in the Kepler field. In addition to studying close-in
planets, Warm Spitzer will have significant application in sensitive imaging
searches for young planets at relatively large angular separations from their
parent stars.

I just happened to stumble to this film and checked IMDb for more information: Score 6,7, well... not so bad. Genre: scifi...good I like scifi. So I got the movie and I was looking forward to have a relaxing Sunday evening watching it. But but...NO.<br /><br />As in summary, this isn't a movie at all. It is a religious advertisement, including: preatching about Jesus, god, devil, end of the world etc. Movie starts with a epic abduction story: Driving at night, car stops, bright light and so on... Well, actually that was the film. Last of this ..ummm... frankly I don't know what to call it...was dialogue about end of the world and last judgement. Quite a same stuff what these TV-preachers tell you, but they are "good" at it.<br /><br />Honestly, if you wan't to see a scifi movie or something with UFOs, please stay far away from this "thing". It has nothing to do with them. If you want to hear some cuckoo head's opinion what the bible has to say and what you should do. Then go ahead and watch this "thing", but I still prefer going to the church at Sunday.<br /><br />This is complete bull. (and evangelical Christian propaganda, as another users said= Well... I should have red another users comments before I got the movie. <br /><br />(27% of voters have rated this "thing" as 10. Yeah, right. Please, go somewhere else to do your propaganda)

Once again, Doctor Who delivers the goods by the bucket load. It has humour ("You're just making it up as you go along!" "Yup, but I do it brilliantly"), action, monsters (in this case still more kick-ass cybermen), tragedy and scare tactics. In short, just what the doctor ordered (pun intended). The way that the emotions move from one to the other is done so well that there is no feeling of "get on with it". So, chalk up 3 out of the last 4 episodes that have made you laugh, then made you cry, and made you go "eek".<br /><br />In terms of character development, this is clearly the clincher for Noel Clarke's Mickey (and Ricky). Being one of the Doctor's companions, you know that he will do the right thing, and may even suspect the manner that he does it. However, it is still an emotional wrench when he confirms his future path.<br /><br />While "The rise of the Cybermen" had more of the sinister build up to terror, "The Age of Steel" is an all out blast. Like "Alien" compared to "Aliens" - both true classics, but in different ways. Can the series keep it up at this level? Let's hope so.

Compound-tunable embedding potential (CTEP) method is proposed. A fragment of
some chemical compound, "main cluster" in the present paper, is limited by
boundary anions such that the nearest environmental atoms are cations. The CTEP
method is based on constructing the embedding potential as linear combination
of short-range "electron-free" spherical "tunable" pseudopotentials for cations
from nearest environment of the main cluster, whereas the long-range CTEP part
consists of Coulomb potentials from optimized fractional point charges centered
on both environmental cations and anions.
A pilot application of the CTEP method to the fersmite crystal,
CaNb$_2$O$_6$, is performed and a remarkable agreement of the electronic
density and interatomic distances within the fragment with those of the
original periodic crystal calculation is attained. Characteristics of
"atoms-in-compounds" which are of great importance for compound of $f$- and
$d$-elements (Nb in fersmite) are considered on examples of chemical shifts of
$K_{{\alpha}_{1,2}}\ $ and $K_{{\beta}_{1,2}}\ $ lines of X-ray emission
spectra in niobium. A very promising potential of this approach in studying
variety of properties of point defects containing $f$- and heavy $d$-elements
with relativistic effects, extended basis set and broken crystal symmetry
considered is discussed.

The corruption has grown quite brazen. There's supposed to be zero influence by Mammon's spiritless cash over democratic matters such as people's destinies. This thing is wrongful, its agents are depraved. They violate all cosmic and social decency. What I fear is that the townspeople are not prepared to fight off an attack like this, and this industry has been subverting towns in this manner all across the countryside. They have a three-ring binder with all the evil moves they need to make. Will nobody stand up as a democratic hero and stop this wicked thing before it kills lives and nature again? You won't get a "re-do" you know, this is as existential as it is final.

The simplistic model of the classical spacetime foam is considered, which
consists of static wormholes embedded in Minkowski spacetime. We explicitly
demonstrate that such a foam structure leads to a topological bias of
point-like sources which can equally be interpreted as the presence of a dark
halo around any point source. It is shown that a non-trivial halo appears on
scales where the topological structure possesses a local inhomogeneity, while
the homogeneous structure reduces to a constant renormalization of the
intensity of sources. We also show that in general dark halos possess both
(positive and negative) signs depending on scales and specific properties of
topological structure of space.

In Time-Sensitive Networking (TSN), it is important to formally prove per
flow latency and backlog bounds. To this end, recent works apply network
calculus and obtain latency bounds from service curves. The latency component
of such service curves is directly derived from upper bounds on the values of
the credit counters used by the Credit-Based Shaper (CBS), an essential
building-block of TSN. In this paper, we derive and formally prove credit upper
bounds for CBS, which improve on existing bounds.

Reasoning modulo equivalences is natural for everyone, including
mathematicians. Unfortunately, in proof assistants based on type theory,
equality is appallingly syntactic and, as a result, exploiting equivalences is
cumbersome at best. Parametricity and univalence are two major concepts that
have been explored to transport programs and proofs across type equivalences,
but they fall short of achieving seamless, automatic transport. This work first
clarifies the limitations of these two concepts in isolation, and then devises
a fruitful marriage between both. The resulting concept, univalent
parametricity, is an heterogeneous extension of parametricity strengthened with
univalence that fully realizes programming and proving modulo equivalences. In
addition to the theory of univalent parametricity, we present a lightweight
framework implemented in Coq that allows the user to transparently transfer
definitions and theorems for a type to an equivalent one, as if they were
equal. For instance, this makes it possible to conveniently switch between an
easy-to-reason-about representation and a computationally-efficient
representation, as soon as they are proven equivalent. The combination of
parametricity and univalence supports transport \`a la carte: basic univalent
transport, which stems from a type equivalence, can be complemented with
additional proofs of equivalences between functions over these types, in order
to be able to lift more programs and proofs, as well as to yield more efficient
terms. We illustrate the use of univalent parametricity on several examples,
including a recent integration of native integers in Coq.

We experimentally demonstrate the emergence of a purely azimuthally polarized
vectorial vortex beam with a phase singularity upon Brewster reflection of
focused circularly polarized light from a dielectric substrate. The effect
originates from the polarizing properties of the Fresnel reflection
coefficients described in Brewster's law. An astonishing consequence of this
effect is that the reflected field's Cartesian components acquire local phase
singularities at Brewster's angle. Our observations are crucial for
polarization microscopy and open new avenues for the generation of exotic
states of light based on spin-to-orbit coupling, without the need for
sophisticated optical elements.

Factory machinery is prone to failure or breakdown, resulting in significant
expenses for companies. Hence, there is a rising interest in machine monitoring
using different sensors including microphones. In the scientific community, the
emergence of public datasets has led to advancements in acoustic detection and
classification of scenes and events, but there are no public datasets that
focus on the sound of industrial machines under normal and anomalous operating
conditions in real factory environments. In this paper, we present a new
dataset of industrial machine sounds that we call a sound dataset for
malfunctioning industrial machine investigation and inspection (MIMII dataset).
Normal sounds were recorded for different types of industrial machines (i.e.,
valves, pumps, fans, and slide rails), and to resemble a real-life scenario,
various anomalous sounds were recorded (e.g., contamination, leakage, rotating
unbalance, and rail damage). The purpose of releasing the MIMII dataset is to
assist the machine-learning and signal-processing community with their
development of automated facility maintenance. The MIMII dataset is freely
available for download at: https://zenodo.org/record/3384388

What was this horrible thing that Trump said? What I have seen discussed as the biggest issue was him saying that both protesters and counter protesters are responsible for the violence. Why is that the most horrible thing ever uttered by a President? It's been difficult to get past all of the emotion and really understand what is so inaccurate/inappropriate. What did he say exactly that is giving people nightmares?

Inspired by a recent work about distribution frames, the definition of
multiplier operator is extended in the rigged Hilbert spaces setting and a
study of its main properties is carried on. In particular, conditions for the
density of domain and boundedness are given. The case of Riesz distribution
bases is examined in order to develop a symbolic calculus.

Multiphase titanium alloys are critical materials in high value engineering
components, for instance in aero engines. Microstructural complexity is
exploited through interface engineering during mechanical processing to realise
significant improvements in fatigue and fracture resistance and strength. In
this work, we explore the role of select interfaces using in-situ
micromechanical testing with concurrent observations from high angular
resolution electron backscatter diffraction (HR-EBSD). Our results are
supported with post mortem transmission electron microscopy (TEM). Using
micro-pillar compression, we performed in-depth analysis of the role of select
{\beta}-titanium (body centred cubic) ligaments which separate neighbouring
{\alpha}-titanium (hexagonal close packed) regions and inhibit the dislocation
motion and impact strength during mechanical deformation. These results shed
light on the strengthening mechanisms and those that can lead to strain
localisation during fatigue and failure.

Worked Great - Really Helped! For Three Days...
Love the design and found it very effective. BUT badly engineered in that the "closed loop" air bladder system is a bad idea. A small filler valve would greatly improve this product as it would allow it to work even after developing small leaks. Mine was very comfortable for a few days then I noticed it lost the bounce. Found the air bladder was no longer holding pressure.

Tomato yield and quality in Iraq have been threatened by a variable range of infections caused by tomato yellow leaf curl virus. In previous studies, the TYLCV isolates were partially characterized using molecular tests for small fragments not the entire length of the virus. Sample of TYLCV-infected tomato has applied in this study to diagnose complete sequence of TYLCV isolate. Three sets of primers that belong to three well-identified strains in Iraq were used in a PCR technique and interestingly the results were negative. A new Iraqi isolate has been characterized as a first novel Iraqi isolate detected ever using next generation (NGS) and bioinformatics techniques. The NGS platform has produced about 78,232,062 paired reads of the TYLCV-infected tomato var. Oula F1. The complete raw reads of the infected variety have been analyzed using RepeatExplorer pipeline and Map to reference. The full sequence of TYLCV was reconstructed and extracted to consist of 2770 nt and then deposited in Genbank under accession number MT583814. Copy numbers and genome proportion of this sequence have been calculated that were 3523 and 0,086% respectively. Phylogenetic analyses of full nucleotide sequences confirmed close relationship to Iranian isolate (TYLCV-Kahnooj) than other published viruses. Additionally, a and {beta} DNA satellites have not discovered in the TYLCV-infected sample.

We consider a dynamical system described by the differential equation
$\dot{Y}_t=-U'(Y_t)$ with a unique stable point at the origin. We perturb the
system by the L\'evy noise of intensity $\varepsilon$ to obtain the stochastic
differential equation $dX^{\varepsilon}_t=-U'(X^{\varepsilon}_{t-})
dt+\varepsilon dL_t.$ The process $L$ is a symmetric L\'evy process whose jump
measure $\nu$ has exponentially light tails,
$\nu([u,\infty))\sim\exp(-u^{\alpha})$, $\alpha>0$, $u\to \infty$. We study the
first exit problem for the trajectories of the solutions of the stochastic
differential equation from the interval $(-1,1)$. In the small noise limit
$\varepsilon\to0$, the law of the first exit time $\sigma_x$, $x\in(-1,1)$, has
exponential tail and the mean value exhibiting an intriguing phase transition
at the critical index $\alpha=1$, namely,
$\ln\mathbf{E}\sigma\sim\varepsilon^{-\alpha}$ for $0<\alpha<1$, whereas
$\ln\mathbf{E}\sigma\sim\varepsilon^{- 1}|\ln\varepsilon|^{1-{1}/{\alpha}}$ for
$\alpha>1$.

I've never actually seen this film but can tell you one thing about its production. While a comedy/oldies radio DJ in 1988, I got a call from the production company. They asked if I'd write and record a bit they'd drop into the soundtrack as sounds eminating from a TV (the television screen itself would never be shown). I said sure, wrote a parody of '50s sci-fi monster clichés, rounded up some sound effects and called in another DJ, Pam Landry, to play the female part. As she happened to be on the air at the time, she put on a long song, joined me at the mike in the production room and we cut the voicetrack in a single take. Giggling, she then went back to her show while I mixed in the goofy sound effects. We'd have never done it if we'd known that "Woodchipper Massacre" was going to be such a turkey -- but, then again, we never got paid for our efforts, either! -- Gary Theroux

Near the horizon of a black brane solution in Anti-de Sitter space, the
long-wavelength fluctuations of the metric exhibit hydrodynamic behaviour. For
Einstein's theory, the ratio of the shear viscosity of near-horizon metric
fluctuations eta to the entropy per unit of transverse volume s is eta/s=1/4
pi. We propose that, in generalized theories of gravity, this ratio is given by
the ratio of two effective gravitational couplings and can be different than
1/4 pi. Our proposal implies that eta/s is equal for any pair of gravity
theories that can be transformed into each other by a field redefinition. In
particular, the ratio is 1/4 pi for any theory that can be transformed into
Einstein's theory; such as F(R) gravity. Our proposal also implies that matter
interactions -- except those including explicit or implicit factors of the
Riemann tensor -- will not modify eta/s. The proposed formula reproduces, in a
very simple manner, some recently found results for Gauss-Bonnet gravity. We
also make a prediction for eta/s in Lovelock theories of any order or
dimensionality.

Orbital differentiation is a common theme in multiorbital systems, yet a
complete understanding of it is still missing. Here, we consider a minimal
model for orbital differentiation in Hund metals with a highly accurate method:
We use the numerical renormalization group as a real-frequency impurity solver
for a dynamical mean-field study of three-orbital Hubbard models, where a
crystal field shifts one orbital in energy. The individual phases are
characterized with dynamic correlation functions and their relation to diverse
Kondo temperatures. Upon approaching the orbital-selective Mott transition, we
find a strongly suppressed spin coherence scale and uncover the emergence of a
singular Fermi liquid and interband doublon-holon excitations. Our theory
describes the diverse polarization-driven phenomena in the $t_{2g}$ bands of
materials such as ruthenates and iron-based superconductors, and our
methodological advances pave the way towards real-frequency analyses of
strongly correlated materials.

Good to see that someone recognizes and acknowledges DeAngelo Henderson's journey from high school to the pros.
Hey, if Henderson continues to break on through to the other side and find his way to the end zone, so much the better.
Denver needs "The Juice" to put fear and plant the seed of doubt in the heart of heartless defenders.
You provided great insight for Denver fans. Thanks, David Southall.
As for DeAngelo, great job!
Way to tote the rock.
Maybe now we can start thinking of a scoring threat whenever a Denver running back goes overland.
We don't want field goals, we want touchdowns.

We investigate the impact of buoyancy on the solute mass transport in an
evaporating liquid mixture (non-volatile solute $+$ solvent) confined in a slit
perpendicular to the gravity. Solvent evaporation at one end of the slit
induces a solute concentration gradient which in turn drives free convection
due to the difference between the densities of the solutes and the solvent.
From the complete model coupling mass transport and hydrodynamics, we first use
a standard Taylor-like approach to derive a one dimensional non-linear
advection-dispersion equation describing the solute concentration process for a
dilute mixture. We then perform a complete analysis of the expected regimes
using both scaling analysis and asymptotic solutions of this equation. The
validity of this approach is confirmed using a thorough comparison with the
numerical resolution of both the complete model and the 1D advection-dispersion
equation. Our results show that buoyancy-driven free convection always impacts
solute mass transport at long time scales, dispersing solutes in a steadily
increasing length scale along the slit. Beyond this confined drying
configuration, our work also provides an easy way for evaluating the relevance
of buoyancy on mass transport in any other microfluidic configuration involving
concentration gradients.

The r-process in a low temperature environment is explored, in which the
neutron emission by photodisintegration does not play a role (cold r-process).
A semi-analytic neutrino-driven wind model is utilized for this purpose. The
temperature in a supersonically expanding outflow can quickly drop to a few
10^8 K, where the (n, gamma)-(gamma, n) equilibrium is never achieved during
the heavy r-nuclei synthesis. In addition, the neutron capture competes with
the beta-decay owing to the low matter density. Despite such non-standard
physical conditions for the cold r-process, a solar-like r-process abundance
curve can be reproduced. The cold r-process predicts, however, the low lead
production compared to that expected in the traditional r-process conditions,
which can be a possible explanation for the low lead abundances found in a
couple of r-process-rich Galactic halo stars.

In the framework of a nonrelativistic chiral quark model, we continue to
study the mass spectra of the fully-heavy $bb\bar{c}\bar{c}$ and
$bc\bar{b}\bar{c}$ tetraquarks. In the present calculations, two structures,
meson-meson [$\bar{Q}Q$][$\bar{Q}Q$] and diquark-antidiquark
[$QQ$][$\bar{Q}\bar{Q}$] ($Q$ = $c$ or $b$), and their mixing, along with all
possible color, spin configurations are considered. The calculations suggest
that no bound state can be formed for $bb\bar{c}\bar{c}$ and $bc\bar{b}\bar{c}$
systems. However, resonances are possible because of the color structure.
Several resonances are predicted and their stabilities are checked using the
real scaling method.

Nonparametric tests via kernel embedding of distributions have witnessed a
great deal of practical successes in recent years. However, statistical
properties of these tests are largely unknown beyond consistency against a
fixed alternative. To fill in this void, we study here the asymptotic
properties of goodness-of-fit, homogeneity and independence tests using
Gaussian kernels, arguably the most popular and successful among such tests.
Our results provide theoretical justifications for this common practice by
showing that tests using Gaussian kernel with an appropriately chosen scaling
parameter are minimax optimal against smooth alternatives in all three
settings. In addition, our analysis also pinpoints the importance of choosing a
diverging scaling parameter when using Gaussian kernels and suggests a
data-driven choice of the scaling parameter that yields tests optimal, up to an
iterated logarithmic factor, over a wide range of smooth alternatives.
Numerical experiments are also presented to further demonstrate the practical
merits of the methodology.

(Abridged) We present R~600, 10-37um spectra of 53 ULIRGs at z<0.32, taken
using the IRS on board Spitzer. All of the spectra show fine structure emission
lines of Ne, O, S, Si and Ar, as well as molecular Hydrogen lines. Some ULIRGs
also show emission lines of Cl, Fe, P, and atomic Hydrogen, and/or absorption
features from C_2H_2, HCN, and OH. We employ diagnostics based on the
fine-structure lines, as well as the EWs and luminosities of PAH features and
the strength of the 9.7um silicate absorption feature (S_sil), to explore the
power source behind the infrared emission in ULIRGs. We show that the IR
emission from the majority of ULIRGs is powered mostly by star formation, with
only ~20% of ULIRGs hosting an AGN with a comparable or greater IR luminosity
than the starburst. The detection of the 14.32um [NeV] line in just under half
the sample however implies that an AGN contributes significantly to the mid-IR
flux in ~42% of ULIRGs. The emission line ratios, luminosities and PAH EWs are
consistent with the starbursts and AGN in ULIRGs being more extincted, and for
the starbursts more compact, versions of those in lower luminosity systems. The
excitations and electron densities in the NLRs of ULIRGs appear comparable to
those of lower luminosity starbursts, though there is evidence that the NLR gas
in ULIRGs is more dense. We show that the combined luminosity of the 12.81um
[NeII] and 15.56um [NeIII] lines correlates with both IR luminosity and the
luminosity of the 6.2 micron and 11.2 micron PAH features in ULIRGs, and use
this to derive a calibration between PAH luminosity and star formation rate.
Finally, we show that ULIRGs with 0.8 < S_sil < 2.4 are likely to be powered
mainly by star formation, but that ULIRGs with S_sil < 0.8, and possibly those
with S_sil > 2.4, contain an IR-luminous AGN.

We perform population synthesis studies of different types of neutron stars
(thermally emitting isolated neutron stars, normal radio pulsars, magnetars)
taking into account the magnetic field decay and using results from the most
recent advances in neutron star cooling theory. For the first time, we confront
our results with observations using {\it simultaneously} the Log N -- Log S
distribution for nearby isolated neutron stars, the Log N -- Log L distribution
for magnetars, and the distribution of radio pulsars in the $P$ -- $\dot P$
diagram. For this purpose, we fix a baseline neutron star model (all
microphysics input), and other relevant parameters to standard values (velocity
distribution, mass spectrum, birth rates ...), allowing to vary the initial
magnetic field strength. We find that our theoretical model is consistent with
all sets of data if the initial magnetic field distribution function follows a
log-normal law with $<\log (B_0/[G])>\sim 13.25$ and $\sigma_{\log B_0}\sim
0.6$. The typical scenario includes about 10% of neutron stars born as
magnetars, significant magnetic field decay during the first million years of a
NS life (only about a factor of 2 for low field neutron stars but more than an
order of magnitude for magnetars), and a mass distribution function dominated
by low mass objects. This model explains satisfactorily all known populations.
Evolutionary links between different subclasses may exist, although robust
conclusions are not yet possible.

We study zero-temperature quantum spin chains which are characterized by a
non-vanishing current. For the XX model starting from the initial state |... +
+ + - - - ...> we derive an exact expression for the variance of the total spin
current. We show that asymptotically the variance exhibits an anomalously slow
logarithmic growth; we also extract the sub-leading constant term. We then
argue that the logarithmic growth remains valid for the XXZ model in the
critical region.

We address the problem of unsupervised domain adaptation (UDA) by learning a
cross-domain agnostic embedding space, where the distance between the
probability distributions of the two source and target visual domains is
minimized. We use the output space of a shared cross-domain deep encoder to
model the embedding space anduse the Sliced-Wasserstein Distance (SWD) to
measure and minimize the distance between the embedded distributions of two
source and target domains to enforce the embedding to be
domain-agnostic.Additionally, we use the source domain labeled data to train a
deep classifier from the embedding space to the label space to enforce the
embedding space to be discriminative.As a result of this training scheme, we
provide an effective solution to train the deep classification network on the
source domain such that it will generalize well on the target domain, where
only unlabeled training data is accessible. To mitigate the challenge of class
matching, we also align corresponding classes in the embedding space by using
high confidence pseudo-labels for the target domain, i.e. assigning the class
for which the source classifier has a high prediction probability. We provide
experimental results on UDA benchmark tasks to demonstrate that our method is
effective and leads to state-of-the-art performance.

We present a characterization of the asymptotics of all asymptotically flat
stationary vacuum solutions of Einstein's field equations. This
characterization is given in terms of two sequences of symmetric trace free
tensors (we call them the `null data'), which determine a formal expansion of
the solution, and which are in a one to one correspondence to Hansen's
multipoles. We obtain necessary and sufficient growth estimates on the null
data to define an absolutely convergent series in a neighbourhood of spatial
infinity. This provides a complete characterization of all asymptotically flat
stationary vacuum solutions to the field equations.

Core-excitation of water ice releases many different molecules and ions in
the gas phase. Studying these desorbed species and the underlying mechanisms
can provide useful information on the effects of X-ray irradiation in ice. We
report a detailed study of the X-ray induced desorption of a number of neutral,
cationic and anionic species from amorphous solid water. We discuss the
desorption mechanisms, and the relative contributions of Auger and secondary
electrons (X-ray induced Electron Stimulated Desorption) and initial excitation
(\rev{direct desorption}) as well as the role of photochemistry. Anions are
shown to desorb not just through processes linked with secondary electrons but
also through direct dissociation of the core-excited molecule. The desorption
spectra of oxygen ions (O$^+$, OH$^+$, H$_2$O$^+$, O$^-$, OH$^-$) give a new
perspective on their previously reported very low desorption yields for most
types of irradiation of water, showing that they mostly originate from the
dissociation of photoproducts such as H$_2$O$_2$.

It is argued that all notions associated with the origin of life should be
related with the participatory anthropic principle of Wheeler and must be
extended into the realm of the multiverse. Also discussed is the notion that
life can only be possible in a given universe during a finite period along
which such a universe expands in an accelerated fashion. We advance finally the
idea that life, cosmic accelerated expansion and quantum theory are nothing but
three distinct faces from a single, unique coin which describes the physical
reality.

We explore the kinetic magnetism of the infinite-$U$ repulsive Hubbard models
at low hole densities on various lattices with nearest-neighbor hopping
integrals modulated by a staggered magnetic flux $\pm\phi$. Tuning $\phi$ from
0 to $\pi$ makes the ground state (GS) change from a Nagaoka-type ferromagnetic
state to a Haerter-Shastry-type antiferromagnetic state at a critical $\phi_c$,
with both states being of kinetic origin. Intra-plaquette spin correlation, as
well as the GS energy, signals such a quantum criticality. This tunable kinetic
magnetism is generic, and appears in chains, ladders and two-dimensional
lattices with squares or triangles as elementary constituents.

This paper is devoted to derive integral representation formulae for the
solution of an inhomogeneous linear wave equation with time-dependent damping
and mass terms, that are scale-invariant with respect to the so-called
hyperbolic scaling. Yagdjian's integral transform approach is employed for this
purpose. The main step in our argument consists in determining the kernel
functions for the different integral terms, which are related to the source
term and to initial data. We will start with the one dimensional case (in
space). We point out that we may not apply in a straightforward way Duhamel's
principle to deal with the source term since the coefficients of lower order
terms make our model not invariant by time translation. On the contrary, we
shall begin with the representation formula for the inhomogeneous equation with
vanishing data by using a revised Duhamel's principle. Then, we will derive the
representation of the solution in the homogeneous case with nontrivial data.
After deriving the formula in the one dimensional case, the classical approach
by spherical means is used in order to deal with the odd dimensional case.
Finally, using the method of descent, the representation formula in the even
dimensional case is proved.

Hints of violation of lepton flavor universality in semileptonic $B$ decays
have prompted a renewed interest in leptoquarks at the low TeV scale. Among the
different scenarios suggested, some happen to violate also lepton number, yet
not much attention has been paid to the expected size of the associated lepton
number violating processes. In this note we examine this issue. We find that
there is a single leptoquark scenario compatible with the current size of the
anomalies which also violates lepton number. In this scenario (Majorana)
neutrino masses are radiatively generated. With the leptoquark parameters
extracted from fitting the flavor anomalies, one actually gets the right order
of magnitude for neutrino masses. We examine the associated effective field
theories both at the electroweak scale and at the hadronic scale and estimate
the size of the most relevant lepton number violating processes.

Visual counting, a task that predicts the number of objects from an
image/video, is an open-set problem by nature, i.e., the number of population
can vary in $[0,+\infty)$ in theory. However, the collected images and labeled
count values are limited in reality, which means only a small closed set is
observed. Existing methods typically model this task in a regression manner,
while they are likely to suffer from an unseen scene with counts out of the
scope of the closed set. In fact, counting is decomposable. A dense region can
always be divided until sub-region counts are within the previously observed
closed set. Inspired by this idea, we propose a simple but effective approach,
Spatial Divide-and- Conquer Network (S-DCNet). S-DCNet only learns from a
closed set but can generalize well to open-set scenarios via S-DC. S-DCNet is
also efficient. To avoid repeatedly computing sub-region convolutional
features, S-DC is executed on the feature map instead of on the input image.
S-DCNet achieves the state-of-the-art performance on three crowd counting
datasets (ShanghaiTech, UCF_CC_50 and UCF-QNRF), a vehicle counting dataset
(TRANCOS) and a plant counting dataset (MTC). Compared to the previous best
methods, S-DCNet brings a 20.2% relative improvement on the ShanghaiTech Part
B, 20.9% on the UCF-QNRF, 22.5% on the TRANCOS and 15.1% on the MTC. Code has
been made available at: https://github. com/xhp-hust-2018-2011/S-DCNet.

Briton killed after New Year's Eve firework explodes in his face in Thailand
Briton killed after New Year's Eve firework explodes in his face in Thailand
A British man has been killed in Thailand after a firework he was lighting exploded in his face.
Gary McLaren, 50, from Corby in Northamptonshire, was celebrating New Year's Eve with his fiancee and a group of friends in Pattaya.

The accident happened on a road full of bars and nightclubs shortly after midnight, according to local police.
Officers arrived around 12.30am and found Mr McLaren on the ground in front of a beer bar, with serious facial injuries.
He received CPR but died at the scene, according to the Bangkok Post.

Mr McLaren is understood to have arrived in Thailand just a few days before.
A witness told the paper she had seen him attempt to light the firework twice, before smoke began pouring out of one end and it exploded.
A large firework was also found nearby and has been taken as evidence.
His fiancee, Jasmine, was seen crying and hugging his body.

She posted a picture of the couple together in tribute: "This is [our] last picture honey, you will be in my heart for ever babe. RIP Gary McLaren."
Bar owner and friend Mike Cooperman shared a photo of Mr McLaren on his birthday, writing: "I will always remember how happy you were that night, RIP Gary, a good friend and brother, Jasmine please accept our deepest condolences and to his family."
The Foreign Office said officials were supporting the family.
Pattaya, around 100 miles from Bangkok, was formerly a small coastal village but has become better known for its nightlife and red light district.

Do not recommend as a gift
I mean sure they’re great towels, but they arrived three days late. “Three days, big deal,” sure sure, except it was a birthday present for my dad and while I built in a day just in case they were late, I did not account for three days late. So beware if you’re buying them as a gift. Thumbs down.

We derive bounds on couplings in the standard model effective field theory
(SMEFT) as a consequence of causality and the analytic structure of scattering
amplitudes. In the SMEFT, there are 64 independent operators at mass dimension
eight that are quartic in bosons (either Higgs or gauge fields) and that
contain four derivatives and/or field strengths, including both CP-conserving
and CP-violating operators. Using analytic dispersion relation arguments for
two-to-two bosonic scattering amplitudes, we derive 27 independent bounds on
the sign or magnitude of the couplings. We show that these bounds also follow
as a consequence of causality of signal propagation in nonvacuum SM
backgrounds. These bounds come in two qualitative forms: i) positivity of
(various linear combinations of) couplings of CP-even operators and ii) upper
bounds on the magnitude of CP-odd operators in terms of (products of) CP-even
couplings. We exhibit various classes of example completions, which all satisfy
our EFT bounds. These bounds have consequences for current and future particle
physics experiments, as part of the observable parameter space is inconsistent
with causality and analyticity. To demonstrate the impact of our bounds, we
consider applications both to SMEFT constraints derived at colliders and to
limits on the neutron electric dipole moment, highlighting the connection
between such searches suggested by infrared consistency.

Great idea if it had worked out for us
It looks easier than it is. I ran around trying to fill this thing with air and it took several tries. I looked ridiculous. Finally got enough air in it to make it work. I sat on it then fell right off. I really think I am missing something. My 12-year old had trouble staying on it as well. We left it next to the tent that night and must have gotten rain because in the morning the thing had water in it...actually inside the liner. Not able to get the water out...and worried about mold...it ended up in the trash. Pretty bummed. The idea is great if it had worked for us.

It's easy to think Long Island is no longer the land of manufacturing.
With the end of high-profile companies like Grumman Corp., and the growth of other key sectors like health care and finance, the Island is no longer as directly and publicly associated with the manufacturing industry as it once was.
Nonetheless, it's still a critical part of the Island's economy — and its future is intrinsically tied to the region's success.
Nassau and Suffolk counties play host to about 3,000 manufacturers and about 70,000 jobs, according to a recent study from the Workforce Development Institute commissioned by a regional manufacturing task force. Perhaps most important, the study found that industry has thousands of open jobs and boasts a relatively high average salary, at $83,358 — critical in a high-cost area like Long Island.
At the same time, however, the industry suffers from a perception problem. It lacks the advocacy that regional business groups bring to other areas of the economy, like real estate development and finance, and unlike the building trades it lacks the support system and educational pipeline to assure that young, skilled workers will be ready to fill the thousands of job openings that exist even now.
Those jobs aren't the widget-making jobs of decades ago. Today, local manufacturers are utilizing robotics and artificial intelligence. Today, they're innovators and engineers. One company on the Island makes and exports tortellini to foreign nations, another makes military-style aircraft seats for military and commercial customers. Going forward, the local manufacturing industry plans to expand its base to include support for offshore wind projects.
To fill the needs, Long Island's community colleges and BOCES facilities have to develop the right certification and professional development programs. They will need to connect with the region's manufacturers to make sure their students' skills meet the companies' requirements. There are models in other parts of the state where successful apprenticeship programs are bridging the gap between student and employee. Additional workforce training, internships and even high school field trips would help both young workers and the companies that hope to employ them, by exposing potential future employees to the opportunities Long Island's manufacturers offer.
But both educators and industry leaders need support. Some advocates have suggested Long Island needs its own region-wide manufacturing association or organization. That might be unnecessary in an area where there are already plenty of business groups, and smaller, more specific industrial organizations, especially if the existing organizations expand their reach to highlight and work with the manufacturing sector.

Forty years ago, nearly 20% of the Island's workers were employed in manufacturing. That number is now down to 5%, but with the right strategy and spotlight, Long Island has the chance to create more jobs in new industries that can represent the region's future, as much as its past.

I study fluid flow at the interface between elastic solids with randomly
rough surfaces. I use the contact mechanics model of Persson to take into
account the elastic interaction between the solid walls and the Bruggeman
effective medium theory to account for the influence of the disorder on the
fluid flow. I calculate the flow tensor which determines the pressure flow
factor and, e.g., the leak-rate of static seals. I show how the perturbation
treatment of Tripp can be extended to arbitrary order in the ratio between the
root-mean-square roughness amplitude and the average interfacial surface
separation. I introduce a matrix D(Zeta), determined by the surface roughness
power spectrum, which can be used to describe the anisotropy of the surface at
any magnification Zeta. I present results for the asymmetry factor Gamma(Zeta)
(generalized Peklenik number) for grinded steel and sandblasted PMMA surfaces.

The winter vacation of Aligarh Muslim University has been extended. The university was scheduled to open on January 6. No new date has been given.
On December 15, the winter vacation was advanced by a week and hostels were vacated after several students were injured in a clash with the police after a protest against the Citizenship (Amendment) Act allegedly turned violent.
An official statement from the public relations office of AMU said due to overall prevailing situation, winter vacation of Aligarh Muslim University for students as well as for the teaching staff, had been extended and the university would not be opening on January 6, 2020.
The decision was taken at a consultative meeting of the Deans of Faculties, Principals of Colleges and Polytechnics and other functionaries of the university under the chairmanship of AMU Vice-Chancellor Professor Tariq Mansoor on Wednesday.
“A detailed schedule for opening of the university in a phased manner, the conduct of remaining examinations which could not be held in December 2019, commencement of classes for the next semester and the duration of the summer vacation shall be notified by the university in due course of time so that there is no academic loss to the students,” said Mujib Ullah Zuberi, Controller of Examination.
He added that students are advised to regularly visit the university website.
Sources said the university administration was waiting for the situation to defuse. “There are 10 thousand non-resident students, many of whom are still carrying on peaceful protest. Many resident students didn’t leave the city and continued to stay with their friends,” said a source requesting anonymity.
Over 60 injured
Over 60 people, including 40 students, AMU security staff and policemen, were injured in the violence. At least four students who received serious injuries are still being treated.
A number of injured students had alleged that police and the Rapid Action Police indulged in excesses. Police have booked 56 persons, including a number of students, for holding a protest which later turned violent.

Once again the common denominator in all of this has been missed, Gordon Butts He has and did destroy Ontario, and now has his sights set on Canada. Junior, Whyne and Mcnutty do not have the brains to pull off this destruction. Mean while India and China are going to build 1000 more coal fired generators that do not even have scrubbers. So what w are doing amounts to nothing in the big scheme of things. One thing it does do is allow Trudeau to grab more taxes on a perceived moral high ground as Canada dies a slow death.

We obtain combinatorial model categories of parametrised spectra, together
with systems of base change Quillen adjunctions associated to maps of parameter
spaces. We work with simplicial objects and use Hovey's sequential and
symmetric stabilisation machines. By means of a Grothendieck construction for
model categories, we produce combinatorial model categories controlling the
totality of parametrised stable homotopy theory. The global model category of
parametrised symmetric spectra is equipped with a symmetric monoidal model
structure (the external smash product) inducing pairings in twisted cohomology
groups.
As an application of our results we prove a tangent prolongation of Simpson's
theorem, characterising tangent $\infty$-categories of presentable
$\infty$-categories as accessible localisations of $\infty$-categories of
presheaves of parametrised spectra. Applying these results to the homotopy
theory of smooth $\infty$-stacks produces well-behaved (symmetric monoidal)
model categories of smooth parametrised spectra. These models provide a
concrete foundation for studying twisted differential cohomology, incorporating
previous work of Bunke and Nikolaus.

... But it is also Minnie's and Pete's too! Yes, the grumpy captain may not look like Pete, but it is! Mickey and Minnie are the best characters, both of them are very sweet and likable. Interestingly, Minnie is more of a lady in this than what she usually is today and Mickey is less than considerate in this than he is now. Pete is still the same old meanie, but he looks a bit different. <br /><br />In this famous episode, on board a little steamboat, Mickey, Minnie and some side characters have a great deal of fun and a great deal of annoyances. Even in their first appearances, the three main characters are very developed. <br /><br />I quite like this episode, although overall I prefer the Mickey Mouse in the future. I like the animation, the steamboat and music theme, the clever gags - and of course, Mickey and Minnie! <br /><br />Like many early cartoons, this is very random, Walt came up with a very basic plot and just added gags to "gear" it along. There is also a parrot side character who is very annoying and rather unnecessary. These are the things I do not like about it. <br /><br />Another interesting thing about this episode, that a colour version has not been made for it (or if it has, I've never heard about it)! <br /><br />Anyone who just enjoys Mickey Mouse and Disney will enjoy this.

In this book we introduce a new procedure called \alpha-Discounting Method
for Multi-Criteria Decision Making (\alpha-D MCDM), which is as an alternative
and extension of Saaty Analytical Hierarchy Process (AHP). It works for any
number of preferences that can be transformed into a system of homogeneous
linear equations. A degree of consistency (and implicitly a degree of
inconsistency) of a decision-making problem are defined. \alpha-D MCDM is
afterwards generalized to a set of preferences that can be transformed into a
system of linear and or non-linear homogeneous and or non-homogeneous equations
and or inequalities. The general idea of \alpha-D MCDM is to assign non-null
positive parameters \alpha_1, \alpha_2, and so on \alpha_p to the coefficients
in the right-hand side of each preference that diminish or increase them in
order to transform the above linear homogeneous system of equations which has
only the null-solution, into a system having a particular non-null solution.
After finding the general solution of this system, the principles used to
assign particular values to all parameters \alpha is the second important part
of \alpha-D, yet to be deeper investigated in the future. In the current book
we propose the Fairness Principle, i.e. each coefficient should be discounted
with the same percentage (we think this is fair: not making any favoritism or
unfairness to any coefficient), but the reader can propose other principles.
For consistent decision-making problems with pairwise comparisons,
\alpha-Discounting Method together with the Fairness Principle give the same
result as AHP. But for weak inconsistent decision-making problem,
\alpha-Discounting together with the Fairness Principle give a different result
from AHP. Many consistent, weak inconsistent, and strong inconsistent examples
are given in this book.

I remember seeing this movie a long time ago, back then even though it didn't have any special effects, the acting was really good. And it still has the same message for today, even though the technology has changed, maybe they should make a remake of this movie, it would be interesting to see a remake. I also enjoyed the music from the movie as well, Larry Norman was a really good songwriter during that time period, although now most Christian music is now worship and praise music. I was always curious to know what ever happened to Patty after the series ended? Did she go on to make more movies, did she get eventually get married and raise a family? I would like to have an update.

We evaluate the mass of the $B_{s0}$ scalar meson and the coupling constant
in the $B_{s0} B K$ vertex in the framework of QCD sum rules. We consider the
$B_{s0}$ as a tetraquark state to evaluate its mass. We get $m_{B_s0}=(6.04\pm
0.08) \GeV$, which is bigger than predictions supposing it as a $b\bar{s}$
state or a $B\bar{K}$ bound state with $J^{P}=0^+$. To evaluate the $g_{B_{s0}B
K}$ coupling we use the three point correlation functions of the vertex,
considering $ B_{s0} $ as a normal $b\bar{s}$ state. The obtained coupling
constant is: $g_{B_{s0} B K} =(16.3 \pm 3.2) \GeV$. This number is in agreement
with light-cone QCD sum rules calculation. We have also compared the decay
width of the $\BS\to BK$ process considering the $\BS$ to be a $b\bar{s}$ state
and a $BK$ molecular state. The width obtained for the $BK$ molecular state is
twice as big as the width obtained for the $b\bar{s}$ state. Therefore, we
conclude that with the knowledge of the mass and the decay width of the $\BS$
meson, one can discriminate between the different theoretical proposals for its
structure.

The low luminosity, X-ray flaring activity, of the sub-class of high mass
X-ray binaries called Supergiant Fast X-ray Transients, has been investigated
using XMM-Newton public observations, taking advantage of the products made
publicly available by the EXTraS project. One of the goals of EXTraS was to
extract from the XMM-Newton public archive information on the aperiodic
variability of all sources observed in the soft X-ray range with EPIC (0.2-12
keV). Adopting a Bayesian block decomposition of the X-ray light curves of a
sample of SFXTs, we picked out 144 X-ray flares, covering a large range of soft
X-ray luminosities (1e32-1e36 erg/s). We measured temporal quantities, like the
rise time to and the decay time from the peak of the flares, their duration and
the time interval between adjacent flares. We also estimated the peak
luminosity, average accretion rate and energy release in the flares. The
observed soft X-ray properties of low-luminosity flaring activity from SFXTs is
in qualitative agreement with what is expected by the application of the
Rayleigh-Taylor instability model in accreting plasma near the neutron star
magnetosphere. In the case of rapidly rotating neutron stars, sporadic
accretion from temporary discs cannot be excluded.

A standard interval exchange map is a one-to-one map of the interval which is
locally a translation except at finitely many singularities. We define for such
maps, in terms of the Rauzy-Veech continuous fraction algorithm, a diophantine
arithmetical condition called restricted Roth type which is almost surely
satisfied in parameter space. Let $T_0$ be a standard interval exchange map of
restricted Roth type, and let $r$ be an integer $\geq 2$. We prove that,
amongst $C^{r+3}$ deformations of $T_0$ which are $C^{r+3}$ tangent to $T_0$ at
the singularities, those which are conjugated to $T_0$ by a $C^r$
diffeomorphism close to the identity form a $C^1$ submanifold of codimension
$(g-1)(2r+1) +s$. Here, $g$ is the genus and $s$ is the number of marked points
of the translation surface obtained by suspension of $T_0$. Both $g$ and $s$
can be computed from the combinatorics of $T_0$.

Animals with complex nervous systems demand sleep for memory consolidation and synaptic remodeling. Here we show that though the Caenorhabditis elegans nervous system has a limited number of neurons and connections, sleep is necessary for both processes. In addition, it is unclear in any system if sleep collaborates with experience to change synaptic connections between specific neurons and whether this ultimately affects behavior. C. elegans neurons have defined synaptic connections and well-described contributions to specific behaviors. We show that spaced odor-training induces long-term memory, and sleep after training is required for long-term memory. Memory consolidation, but not acquisition, requires a pair of interneurons, the AIYs, which play a role in odor-seeking behavior. In worms that have consolidated memory, both sleep and odor conditioning are required to diminish inhibitory synaptic connections between the AWC chemosensory neurons and the AIY interneurons. Thus, we demonstrate in a living organism that sleep is required for events immediately after training that drive memory consolidation and alter synaptic structures.

We present a general procedure to construct the first law of thermodynamics
on the apparent horizon and illustrate its validity by examining it in some
extended gravity theories. Applying this procedure, we can describe the
thermodynamics on the apparent horizon in Randall-Sundrum braneworld imbedded
in a nontrivial bulk. We discuss the mass-like function which was used to link
Friedmann equation to the first law of thermodynamics and obtain its special
case which gives the generalized Misner-Sharp mass in Lovelock gravity.

The dynamics of a quantum system can be simulated using a quantum computer by
breaking down the unitary into a quantum circuit of one and two qubit gates.
The most established methods are the Trotter-Suzuki decompositions, for which
rigorous bounds on the circuit size depend on the number of terms $L$ in the
system Hamiltonian and the size of the largest term in the Hamiltonian
$\Lambda$. Consequently, Trotter-Suzuki is only practical for sparse
Hamiltonians. Trotter-Suzuki is a deterministic compiler but it was recently
shown that randomised compiling offers lower overheads. Here we present and
analyse a randomised compiler for Hamiltonian simulation where gate
probabilities are proportional to the strength of a corresponding term in the
Hamiltonian. This approach requires a circuit size independent of $L$ and
$\Lambda$, but instead depending on $\lambda$ the absolute sum of Hamiltonian
strengths (the $\ell_1$ norm). Therefore, it is especially suited to electronic
structure Hamiltonians relevant to quantum chemistry. Considering propane,
carbon dioxide and ethane, we observe speed-ups compared to standard
Trotter-Suzuki of between $306\times$ and $1591\times$ for physically
significant simulation times at precision $10^{-3}$. Performing phase
estimation at chemical accuracy, we report that the savings are similar.

The transport of H adatoms across oxide supports plays an important role in
many catalytic reactions. We investigate the dynamics of H/Fe3O4(001) between
295 and 382 K. By scanning tunneling microscopy at frame rates of up to 19.6
fps, we observe the thermally activated switching of H between two O atoms on
neighboring Fe rows. This switching rate changes in proximity to a defect,
explained by density functional theory as a distortion in the Fe-O lattice
shortening the diffusion path. Quantitative analysis yields an apparent
activation barrier of 0.94 +/- 0.07 eV on a pristine surface. The present work
highlights the importance of local techniques in the study of atomic-scale
dynamics at defective surfaces such as oxide supports.

We study vertex colorings of the square $G^2$ of an outerplanar graph $G$. We
find the optimal bound of the inductiveness, chromatic number and the clique
number of $G^2$ as a function of the maximum degree $\Delta$ of $G$ for all
$\Delta\in \nats$. As a bonus, we obtain the optimal bound of the choosability
(or the list-chromatic number) of $G^2$ when $\Delta \geq 7$. In the case of
chordal outerplanar graphs, we classify exactly which graphs have parameters
exceeding the absolute minimum.

Wish it was more adjustable
I didn’t receive the one on the picture. I got Lightning and Mater in a Cars 2 scene. It’s a little blurry when projected on the wall or ceiling. It’s not adjustable enough, we can barely get the whole picture on the ceiling from any of our outlets. It’s cute, my kid likes it, but it’s not very high quality.

This movie was the second movie I saw on the cinema as a child. It scared the living crap out of me. So much so that I asked my father if we could leave halfway through.<br /><br />Nowadays, the only people leaving halfway through are the ones who have a good taste in movies.<br /><br />I, however, still have fond memories of this flawed masterpiece of awfulness. Doug McClure and Peter Cushing in the same movie! Great! Monsters made of polypropylene substitute. Scary stuff. A rubber monster is, when you think about it, is even scarier than a real monster.<br /><br />The astonishing thing about this movie is how good the score is. Truly rousing stuff.<br /><br />There's also plenty of prehistoric tit on show, too. Nice.

Was not impressed
I thought the case was going to be a good one, however it did not line up with the buttons on my phone correctly. Also, my charger did not fit into the hole that was made for the charging cord to go into. So, I could not charge my phone nor could I turn my phone on and off using the power button with this case on. It would let me work the volume buttons however, which I thought was strange. I have a Samsung Galaxy S8.

Well...I always thought being in the police force was service. Heck, even got my nose broken while handcuffing a guy fleeing from an armed robbery. But as for being "sweet fat temp. positions" Well, being a volunteer fireman is, as the job title implies, volunteer work, and it is unpaid. I was a reserve police officer during my college years as I could fit the shifts in between classes and on weekends to help pay for college...it didn't pay much at all, but I needed a flexible job! Sorry you're down on the police force, it's a tough job and the thanks are few and far between. Still have a lot of friends there, good folks doing a needed service.

WEBS is a pretty odd movie, albeit slightly watchable. Richard Grieco plays an electrician who gets suck into a parallel Earth overrun by mutant spiders, or something like that. The film itself was made with a modest budget, which explains the limited locales, and the somewhat tedious screenplay that manages to do very little with quite an interesting premise. Basically a 90 minute episode of the TV show "Sliders", and nothing more.<br /><br />4 out of 10<br /><br />(go to www.nixflix.com for a more detailed review and reviews of other films in the genre)

The spontaneous motion of liquid droplets on solid surfaces is the result of
an unbalanced surface tension force, which is sometimes called the "Marangoni
effect". This can be triggered by either a difference in surface temperature or
a heterogeneity in the topography or chemistry of the surface passively or
actively. The imbibition of liquid within capillary tubes, horizontal ice
wicking on either hydrophilic or hydrophobic substrates, and inkjet printing
for example are just some classic illustrations of where the Lucas-Washburn
equation can predict droplet behavior characteristics fairly well. In contrast,
this study reveals an example of droplet behavior not previously studied that
is not well-predicted by the Lucas-Washburn equation, namely the motion of
ferrofluid droplets in the presence of uniform magnetic field. When a
ferrofluid droplet is horizontally exposed to an external uniform magnetic
field on a biphilic surface tension gradient in the shape of a wedge, it
appears to violates the Lucas-Washburn equation which predicts that droplet
travel distance should scale with the square root of time (i.e. l~t^(1/2)).
Rather, our experimental results suggest that the movement of the ferrofluid
droplet is slower following the relationship, (l~t^(1/3)). Furthermore, due to
the relatively high viscosity of water-based ferrofluid droplets, we observed
that at the beginning of the motion, the visco-capillary effect dominates the
effects of the magnetism, and the droplets tend to follow the well-known
relationship, (l~t^(1/10)). This initial stage of droplet spreading is known as
"Tanner's Law".

We use a probabilistic approach to study the rate of convergence to
equilibrium for a collisionless (Knudsen) gas in dimension equal to or larger
than 2. The use of a coupling between two stochastic processes allows us to
extend and refine, in total variation distance, the polynomial rate of
convergence given in [AG11] and [KLT13]. This is, to our knowledge, the first
quantitative result in collisionless kinetic theory in dimension equal to or
larger than 2 that does not require any symmetry of the domain, nor a
monokinetic regime. Our study is also more general in terms of reflection at
the boundary: we allow for rather general diffusive reflections and for a
specular reflection component.

Every quasigroup $(S,\cdot)$ belongs to a set of 6 quasigroups, called
parastrophes denoted by $(S,\pi_i)$, $i\in \{1,2,3,4,5,6\}$. It is shown that
isotopy-isomorphy is a necessary and sufficient condition for any two distinct
quasigroups $(S,\pi_i)$ and $(S,\pi_j)$, $i,j\in \{1,2,3,4,5,6\}$ to be
parastrophic invariant relative to the associative law. In addition, a
necessary and sufficient condition for any two distinct quasigroups $(S,\pi_i)$
and $(S,\pi_j)$, $i,j\in \{1,2,3,4,5,6\}$ to be parastrophic invariance under
the associative law is either if the $\pi_i$-parastrophe of $H$ is equivalent
to the $\pi_i$-parastrophe of the holomorph of the $\pi_i$-parastrophe of $S$
or if the $\pi_i$-parastrophe of $H$ is equivalent to the $\pi_k$-parastrophe
of the $\pi_i$-parastrophe of the holomorph of the $\pi_i$-parastrophe of $S$,
for a particular $k\in \{1,2,3,4,5,6\}$.

Early implantable epilepsy therapy devices provided open-loop electrical stimulation without brain sensing, computing, or an interface for synchronized behavioral inputs from patients. Recent epilepsy stimulation devices provide brain sensing but have not yet developed analytics for accurately tracking and quantifying behavior and seizures. Here we describe a distributed brain co-processor providing an intuitive bi-directional interface between patient, implanted neural stimulation and sensing device, and local and distributed computing resources. Automated analysis of continuous streaming electrophysiology is synchronized with patient reports using a hand-held device and integrated with distributed cloud computing resources for quantifying seizures, interictal epileptiform spikes, and patient symptoms during therapeutic electrical brain stimulation. The classification algorithms for interictal epileptiform spikes and seizures were developed and parameterized using long-term ambulatory data from 9 humans and 8 canines with epilepsy, and then implemented prospectively in out-of-sample testing in 2 pet canines and 4 humans with drug resistant epilepsy living in their natural environments.

"I have looked into the eye of this island, and what I saw was beautiful," proclaims one of the main characters in ABC's award winning television show "Lost". The series could be summarized as a drama story about a group of plane crash survivors stranded on an unknown island, but that would be doing the show a disservice. "Lost" follows a large group of characters who come into conflict with the island, each other, and ultimately themselves as they struggle with their new way of life and their dependency on each other. The situation becomes more complicated when it becomes clear this isn't an ordinary island, either - and that they may not be alone.<br /><br />My initial fear after hearing the concept of this series was the lack of new stories they could tell us after a certain period, but this proved to be unfounded. The narrative flows naturally, the dialogue is witty, the characters are memorable and the execution is superb. The island is a character all on its own, and to understand this comment you'd have to see the series for yourself, which only goes to show its originality and greatness.<br /><br />At the time of writing this review, only the first two seasons have aired, and they're filled with strong episodes. My only mild criticism is that the second season seems to slow down a bit halfway, but then fortunately comes back in admirable shape for the final episodes.<br /><br />If I can recommend one television series you should be following right now, it would certainly be this one. If you like excitement, adventure, character driven stories, an extremely strong cast and crew, beautiful locations, and an island that seems more spiritual than natural, "Lost" is for you. Just be sure you start at the beginning.

This paper introduces new solvers for the computation of low-rank approximate
solutions to large-scale linear problems, with a particular focus on the
regularization of linear inverse problems. Although Krylov methods
incorporating explicit projections onto low-rank subspaces are already used for
well-posed systems that arise from discretizing stochastic or time-dependent
PDEs, we are mainly concerned with algorithms that solve the so-called nuclear
norm regularized problem, where a suitable nuclear norm penalization on the
solution is imposed alongside a fit-to-data term expressed in the 2-norm: this
has the effect of implicitly enforcing low-rank solutions. By adopting an
iteratively reweighted norm approach, the nuclear norm regularized problem is
reformulated as a sequence of quadratic problems, which can then be efficiently
solved using Krylov methods, giving rise to an inner-outer iteration scheme.
Our approach differs from the other solvers available in the literature in
that: (a) Kronecker product properties are exploited to define the reweighted
2-norm penalization terms; (b) efficient preconditioned Krylov methods replace
gradient (projection) methods; (c) the regularization parameter can be
efficiently and adaptively set along the iterations. Furthermore, we
reformulate within the framework of flexible Krylov methods both the new
inner-outer methods for nuclear norm regularization and some of the existing
Krylov methods incorporating low-rank projections. This results in an even more
computationally efficient (but heuristic) strategy, that does not rely on an
inner-outer iteration scheme. Numerical experiments show that our new solvers
are competitive with other state-of-the-art solvers for low-rank problems, and
deliver reconstructions of increased quality with respect to other classical
Krylov methods.

Malfunctioned within one month
I've bought two of these, a couple of weeks apart. Unfortunately, one malfunctioned within a month, after only 4 uses. Part of the coupling which attaches to the USB cable came apart. Luckily the drive was still intact, but I had to buy a new temporary housing, pay for repair service and will still need to buy another Hard drive.

Within a few-body formalism, we develop a general theory of surrogate nuclear
and atomic reactions with the excitation of a resonance in the intermediate
binary subsystem leading to three charged particles in the final state. The
Coulomb interactions between the spectator and the resonance in the
intermediate state and between the three particles in the final state are taken
into account. Final-state three-body Coulomb multiple-scattering effects are
accounted for using the formalism of the three-body Coulomb asymptotic states
based on the work published by one of us (A.M.M.) under the guidance of L. D.
Faddeev. An expression is derived for the triply differential cross section. It
can be used for investigation of the Coulomb effects on the resonance line
shape as well as the energy dependence of the cross section. We find that
simultaneous inclusion of the Coulomb effects in the intermediate and final
state decreases the effect of the final-state Coulomb interactions on the
triply differential cross section.

Assy McGee is a show that you really have to be a certain age to appreciate. Otherwise, it's likely you'll miss the references to 80's cop films and simply think it's a running gag about a walking rectum. Think it's brainless, infantile poop humor? Go watch the Stallone film 'Cobra' and you'll see what I mean. This show actually has very subtle humor, which says a lot, both for a show that aired on adult swim, and for a show about a walking ass.<br /><br />All the standard genre clichés are in place that made movies like Dirt Harry and Cobra so great and ripe for parody. Sanchez is Assy's partner, who is - as per the genre - level-headed and constantly apologizing for his partner's homicidal behavior. The police chief is, of course, a fire-breathing hard case who lives to scream "I want your badge on my desk first thing tomorrow morning!" The over-the-top, and sometimes completely nonsensical manner in which the 1980's 'Renegade Cop' film is parodied suits the subject matter well. For instance, while breaking up a bus robbery, one of the criminals stops to ask Assy, "Hey, where are you going, asshole!?" To which the title character snaps off the one-liner: "I'm going... to shoot you." <br /><br />Highly recommended for anybody who loves 80's action movies, and has actually viewed enough of them to understand the humor.

Broken pepper milk, made of plastic, not metal
These are PLASTIC! The pepper milk didn’t work. I probably would’ve kept them despite the plasticy feel if they both worked, but as it was, I returned them. They actually looked great, despite the material, but I at least need both to work!

Chain event graphs have been established as a practical Bayesian graphical
tool. While bespoke diagnostics have been developed for Bayesian Networks, they
have not yet been defined for the statistical class of Chain Event Graph
models. Mirroring the methodology of prequential diagnostics for Bayesian
Networks, in this paper we design a number of new Bayesian diagnostics for this
new class. These can be used to check whether a selected model--presumably the
best within the class--captures most of the salient features of the observed
process. These are designed to check the continued validity of a selected model
as data about a population is collected. A previous study of childhood illness
in New Zealand illustrates the efficacy of these diagnostics. A second example
on radicalisation is used as a more expressive example.

High field Q-slope (HFQS) seriously limits the high gradient performance of
the buffered chemically polished (BCP) superconducting radio frequency (SRF)
niobium cavities. The direct cause or mechanism is not yet fully understood. In
our recent extensive data analysis, we concluded that the potential root cause
could be nitrogen contamination on the surface. The nitric contamination could
be created by nitric acid during BCP which uses the mixture of hydrofluoric
acid, nitric acid, and phosphoric acid. Based on this thought, we started to
develop a new chemical polishing acid that replaces the nitric acid by hydrogen
peroxide. We have discovered that this new acid cannot provide smooth surface
finishing, however adding copper catalyst allows this acid to provide a smooth
surface similar to or even better than that from the conventional BCP. This
paper first shows the significance of resolving HFQS, then summarizes our
extensive data analysis results, and finally describes our discovery of the
copper catalyst.

Watch, O Lord, with those who wake, or watch, weep or sleep this day, and give Your angels and saints charge over all those who worry and are frightened.
Tend Your sick ones, O Lord Christ.
Rest Your weary ones.
Bless Your dying ones.
Soothe Your suffering ones.
Pity Your afflicted ones.
Shield Your joyous ones, and all for Your love's sake.
Make us instruments of your peace, and a sign of your love for us... Amen

Suddenly releases mid drive.
The car mount holds and charge my Xs max fine with case. Just one issue. It suddenly like to release every once in awhile during my drive which is a bit annoying. I wouldn’t purchase again because it fails to securely hold my phone during drive and don’t want to worry about it falling mid drive.

Rowan Atkinson's Mr. Bean ranks right up there with Laurel & Hardy, Buster Keaton, the Marx Brothers and other comedy greats. I have never seen people laugh out loud so heartily and literally fall out of their chairs as when I introduced them to Mr. Bean via my videos and now DVDs. I'll never forget the first time my brother saw him. He was over for a visit and I asked him if he'd ever seen Mr. Bean? "Who?" he said. So I got out my video and showed him the one where Mr. Bean is in church and starts to nod off. My brother laughed so hard he fell out of the chair and was holding his stomach from laughing so hard. He became an instant fan of Mr. Bean. We all know how hilarious these episodes are, but the fun is in sharing them with others. I have seen so many people laugh 'til it hurts! Favorite episodes are: the visit of the Queen, the Hotel room stay, late for the Dentist appointment, the Christmas episode (a classic...plus kids love it!) and the New Year Party. Rowan Atkinson is a comic genius!

In this work fluctuations in the electric field of surface plasmon polaritons
undergoing random scattering on a rough metallic surface are considered. A
rigorous closed form analytic expression is derived describing second order
correlations in the resulting plasmon speckle pattern assuming statistically
stationary and isotropic roughness. Partially coherent planar Schell-model
source fields can also be described within the developed framework. Behaviour
of the three-dimensional degree of cross polarisation and spectral degree of
coherence is also discussed. Expressions derived take full account of
dissipation in the metal with non-universal behaviour exhibited within the
correlation length of the surface and source fields.

The tensor force, as an important component of strong nuclear force,
generates a variety of intriguing effects ranging from few-body systems to
neutron stars. It is responsible for the nucleon-nucleon correlation beyond
mean-field approximation, and is accordingly proved to play no role in the
standard Skyrme energy density functionals in the present work. Therefore, the
Skyrme's original tensor interaction that is extensively-employed presently is
invalid. As an alternative strategy, we introduced a central interaction, i.e.,
the $\bm{\sigma }_{1}\cdot \bm{\sigma }_{2}$ term, to improve the description
of experimental single-particle structure, and to address its effect, we
established two Skyrme interactions IMP1 and IMP2 complemented by the
calibrated charge-violating interactions. The central $\bm{\sigma }_{1}\cdot
\bm{\sigma }_{2}$ interaction turns out to substantially improve the
description of shell evolution in Sn isotopes and $N=82$ isotones.

While current General Game Playing (GGP) systems facilitate useful research
in Artificial Intelligence (AI) for game-playing, they are often somewhat
specialised and computationally inefficient. In this paper, we describe the
"ludemic" general game system Ludii, which has the potential to provide an
efficient tool for AI researchers as well as game designers, historians,
educators and practitioners in related fields. Ludii defines games as
structures of ludemes -- high-level, easily understandable game concepts --
which allows for concise and human-understandable game descriptions. We
formally describe Ludii and outline its main benefits: generality,
extensibility, understandability and efficiency. Experimentally, Ludii
outperforms one of the most efficient Game Description Language (GDL)
reasoners, based on a propositional network, in all games available in the
Tiltyard GGP repository. Moreover, Ludii is also competitive in terms of
performance with the more recently proposed Regular Boardgames (RBG) system,
and has various advantages in qualitative aspects such as generality.

Here, we explore the prospects of carrying out the single qubit spectroscopy
of environmental noise when the resolution of the frequency filters produced by
the dynamical decoupling pulse sequences can be set high enough to reveal the
discrete structure of the noise spectral density. The standard form of
spectroscopy is applicable when the filter is unable to resolve the discrete
spectral lines and only coarse grained approximation of the spectrum is
recorded in the qubit's decoherence rate. When the discrete structure becomes
accessible, the qubit probe evolves in a qualitatively different manner, and
the procedure for recovering spectral density has to be redesigned.

The reasons for the anomalously high thermal stability of cubane C8H8 and the
mechanisms of its decomposition are studied by numerically simulating the
dynamics of this metastable cluster at T = 1050 - 2000 K using a tight-binding
potential. The decomposition activation energy is found from the temperature
dependence of the cubane lifetime obtained from the numerical experiment; this
energy is fairly high, Ea = 1.8 - 2.0 eV. The decomposition products are, as a
rule, either C6H6 and C2H2 molecules or the isomer C8H8 with a lower energy.

This year started with such promise, as NASA’s spacecraft New Horizons flew by the most distant world ever explored.
The unmanned mission, a scientific miracle, delivered a stirring January message about American ingenuity, humanity, and the mysteries of the universe. The rest of 2019 was less lofty.
It was a year of grinding politics. A rookie Democratic-controlled State Legislature went through a jam-packed and sometimes chaotic legislative session, from overdue voting changes to complicated criminal justice reforms. Local fraud and abuse continued as usual, with the convictions of former Nassau County Executive Edward Mangano and former Suffolk County District Attorney Thomas Spota.
All the while, Washington was a tempest, with special counsel Robert Mueller’s investigation into Russian interference in the 2016 election coming and going. White House scandals and travesties popped from the Mexican border to Ukraine.
Ultimately, 2019 saw just the third impeachment of an American president.
There were devastating storms over the Bahamas and fires in California as climate change created havoc around the globe. The world seemed to spiral, with protests in Hong Kong and authoritarian or populist movements gaining steam from India to Eastern Europe to Britain. American troops continued to fight and die in the Middle East, as the truth about the long war in Afghanistan only continued to come out.
There were bright spots. Yankee great Mariano Rivera was unanimously voted into baseball’s Hall of Fame, and the U.S. Women’s soccer team dominated the World Cup. Even Congress made the belated promise to care for 9/11 first responders permanent.
Those good moments can be hard to clock. With a presidential election coming, time will only speed up. But some things endure, like that New Horizons mission. The spacecraft is still transmitting data from the January flyby. And it’s still healthy, traveling 31,000 mph toward future discoveries, more and more distant from Earth.

We report spectroscopic confirmation and high-resolution infrared imaging of
a z=2.79 triply-imaged galaxy behind the Bullet Cluster. This source, a
Spitzer-selected luminous infrared galaxy (LIRG), is confirmed via polycyclic
aromatic hydrocarbon (PAH) features using the Spitzer Infrared Spectrograph
(IRS) and resolved with HST WFC3 imaging. In this galaxy, which with a stellar
mass of M*=4e9 Msun is one of the two least massive ones studied with IRS at
z>2, we also detect H_2 S(4) and H_2 S(5) pure rotational lines (at 3.1 sigma
and 2.1 sigma) - the first detection of these molecular hydrogen lines in a
high-redshift galaxy. From the molecular hydrogen lines we infer an excitation
temperature T=377+68-84 K. The detection of these lines indicates that the warm
molecular gas mass is 6(+36-4)% of the stellar mass and implies the likely
existence of a substantial reservoir of cold molecular gas in the galaxy.
Future spectral observations at longer wavelengths with facilities like the
Herschel Space Observatory, the Large Millimeter Telescope, and the Atacama
Pathfinder EXperiment (APEX) thus hold the promise of precisely determining the
total molecular gas mass. Given the redshift, and using refined astrometric
positions from the high resolution imaging, we also update the magnification
estimate and derived fundamental physical properties of this system. The
previously published values for total infrared luminosity, star formation rate,
and dust temperature are confirmed modulo the revised magnification; however we
find that PAH emission is roughly a factor of five stronger than would be
predicted by the relations between the total infrared and PAH luminosity
reported for SMGs and starbursts in Pope et al. (2008).
