"There are only 2 possibilities. Either 1) Trump is lying, or 2) his lawyer is lying by putting tons of makeup in Trump's admission that he was being investigated."
There is a third possibility, which is substantiated by the facts: Trump's lawyer has not been informed that Trump is being investigated for the Russia connection, but he is being investigated for obstruction of justice in trying to shut down that investigation.

Terry Benedict (Andy Garcia) catches up with Danny Ocean and his team and demands that they repay the money that they stole from him (in Oceans 11) plus interest. He holds back from violent action however as he is under the instruction of the world's greatest thief, the Night Fox. The team then have to pull off a series of heists to pay Benedict back whilst testing their abilities against the Night Fox who wishes to maintain his position as the greatest thief ever. Put simply, this film is a complete mess. The masses may argue that it is "cool" and that Clooney and Pitt put in great performances but these are the same people who have a subscription to "Hello" magazine and think that David Beckham has the potential to be a great actor. The story is convoluted, it is not complex or clever and it does not have intelligent twists and turns, it is just a complete mess that spills out in multiple directions with the hope that the audience will think it is cool and intelligent (Hello magazine readers). Any respectable movie watcher will however see the film for the farce that it is. Whilst Oceans 11 wasn't a great film it had a decent pace, was stylish and had some decent twists and turns. This movie loses its way very quickly and then basically gives up. It is as if the director and cast said to themselves, hey this isn't really working out, lets just have a laugh! Indeed the cast looks like they are enjoying themselves but I was not. I will not delve into the plot as its confused evolution does not warrant any examination. The addition of Catherine Zeta Jones is largely annoying. The scenes where Julia Roberts impersonates herself (with Bruce Willis undertaking a cameo role) whilst mildly amusing appear to be a desperate move to keep the audience interested. The movie is so full of plot holes that it as if Arnie has emptied an Uzi 9mm into the film studio. Credit can only be given to some scenes where the Night Fox uses Caopeira to undertake a heist against the back drop of some funky music but this is hardly justification to watch the movie. The final scene features the team in a nonsensical drunken stupor; this accurately sums up the movie. Stick with the original.

Hand segmentation and fingertip detection play an indispensable role in hand
gesture-based human-machine interaction systems. In this study, we propose a
method to discriminate hand components and to locate fingertips in RGB-D
images. The system consists of three main steps: hand detection using RGB
images providing regions which are considered as promising areas for further
processing, hand segmentation, and fingertip detection using depth image and
our modified SegNet, a single lightweight architecture that can process two
independent tasks at the same time. The experimental results show that our
system is a promising method for hand segmentation and fingertip detection
which achieves a comparable performance while model complexity is suitable for
real-time applications.

During the last decades, the problem of malicious and unwanted software
(malware) has surged in numbers and sophistication. Malware plays a key role in
most of today's cyber attacks and has consolidated as a commodity in the
underground economy. In this work, we analyze the evolution of malware from
1975 to date from a software engineering perspective. We analyze the source
code of 456 samples from 428 unique families and obtain measures of their size,
code quality, and estimates of the development costs (effort, time, and number
of people). Our results suggest an exponential increment of nearly one order of
magnitude per decade in aspects such as size and estimated effort, with code
quality metrics similar to those of benign software.We also study the extent to
which code reuse is present in our dataset. We detect a significant number of
code clones across malware families and report which features and
functionalities are more commonly shared. Overall, our results support claims
about the increasing complexity of malware and its production progressively
becoming an industry.

Recent high-pressure studies found that superconductivity can be achieved
under very low pressure in the parent iron arsenide compound CaFe2As2, although
details of the sharpness and temperature of transitions vary between liquid
medium and gas medium measurements. To better understand this issue, we
performed high-pressure susceptibility and transport studies on CaFe2As2, using
helium as the pressure medium. The signatures of the transitions to the
low-temperature orthorhombic and collapsed tetragonal phase remained
exceptionally sharp and no signature of bulk superconductivity was found under
our hydrostatic conditions. Our results suggest that phase separation and
superconductivity in CaFe2As2 are induced by non-hydrostatic conditions
associated with the frozen liquid media.

Very comfortable and stylish band, but will it last?
Received the band just four days ago and have really been impressed with the look and comfort. However, after just four days I noticed a split starting on one of the holes that the post inserts into. So far so good, but concerned about the possibility of losing my Fitbit.

We have performed a systematic search for X-ray cavities in the hot gas of 51
galaxy groups with Chandra archival data. The cavities are identified based on
two methods: subtracting an elliptical beta model fitted to the X-ray surface
brightness, and performing unsharp masking. 13 groups in the sample 25% are
identified as clearly containing cavities, with another 13 systems showing
tentative evidence for such structures. We find tight correlations between the
radial and tangential radii of the cavities, and between their size and
projected distance from the group center, in quantitative agreement with the
case for more massive clusters. This suggests that similar physical processes
are responsible for cavity evolution and disruption in systems covering a large
range in total mass. We see no clear association between the detection of
cavities and the current 1.4 GHz radio luminosity of the central brightest
group galaxy, but there is a clear tendency for systems with a cool core to be
more likely to harbor detectable cavities. To test the efficiency of the
adopted cavity detection procedures, we employ a set of mock images designed to
mimic typical Chandra data of our sample, and find that the model-fitting
approach is generally more reliable than unsharp masking for recovering cavity
properties. Finally, we find that the detectability of cavities is strongly
influenced by a few factors, particularly the signal-to-noise ratio of the
data, and that the real fraction of X-ray groups with prominent cavities could
be substantially larger than the 25--50% suggested by our analysis.

Variations of the optical continuum emission in the radio galaxy 3C 390.3 are
compared to the properties of radio emission from the compact, sub-parsec-scale
jet in this object. We showed that very long-term variations of optical
continuum emission (>10 years) is correlated with the radio emission from the
base of the jet located above the disk, while the optical long-term variations
(1-2 years) follows the radio flares from the stationary component in the jet
with time delay of about 1 year. This stationary feature is most likely to be a
standing shock formed in the continuous relativistic flow seen at a distance of
~0.4 parsecs from the base of the jet. To account for the correlations observed
we propose a model of the nuclear region of 3C 390.3 in which the beamed
continuum emission from the jet and counterjet ionizes material in a
subrelativistic outflow surrounding the jet. This results in the formation of
two conical regions with double-peaked broad emission lines (in addition to the
conventional broad line region around the central nucleus) at a distance ~0.6
parsecs from the central engine.

I HATE THIS MOVIE!!!!!! I have never seen such utter, complete trash in my life!!! I live in France so it turned out that I was in the front line to watch this awful movie. At first, it seemed cool, kind of like something about a cursed forest that chomps people. Unfortunately, it turned out it was something QUITE different: a good start with a girl that meets a guy and all that whatnot, then the girl gets threatening messages in the form of ravens shut up in her bathroom closet(ludicrous), from that bit and on, the movie starts to slide downhill very quickly with a lot of desperate thrashing in the process. The movie ends with sacrificial druids galore and ancient ugly, stinky creatures coming back from the past to kill a few people. Many questions were rushing around my head by then: why the heck did they bring back that scummy monster? Do druids look like maniacs dressed in bedsheets? Why did they even bother making this movie?? The "climax" of the movie was so goofy I laughed all the way through it: the "awful" stinky monster does battle with the two young women(who appear to be expert kung fu masters) and the professor gets sliced in two or something. What surprised me was that the monster was so slow and ungainly in battle, wasn't it supposed to be a god of war or something? Anyway, the movie in it's death throws was a pitiful sight. A brief condensation of the contents of this movie: Kung fu mayhem+druid stones+mysterious murders "à la thriller"+ancient prophecies+shabby ravens+old clumsy boneless war god+nutty professor=complete and utter, diseased, boneless, worm eaten, GODFORSAKEN, GODDAM, RECYCLED, FAKE, WANNABE, LUDICROUS SH*T!!!!!!!!! Things I learned from this movie: -Ancient war gods are lousy at kung fu. -All young women who study archeology at university in France are kung fu experts. -Professors are so resistant they can survive being sliced in two by a saw-mass-whatchamacallit without any injuries.

A thinly veiled attempt to push Hulkamania to the film going non-wrestling fan. What could be worse than Hogan in the movies? Bad actors in the wrestling ring, and this film produced both, as Tiny Lester made his way to the WWE that summer in the mother of all promotional blunders. See the dictionary under Oops. As a card carrying member of the stupid kids of the world paid to see this in theaters and when I came out I immediately checked into H.A. - Hulkamaniacs Annoynimous. I am proud to say I have been off the Hulk for 17 years now and have never had a craving since. Since this was made to bring in more fans to the juggernaut that was the WWE in Hogans hey day one has to wonder if there weren't more fans like me who turned to other past times that did not poison ones mind like this offense to celluloid did, such as huffing gas or Russian Roulette.

Optical absorption spectra of poly(thiophene vinylene) (PTV) conjugated
polymers have been studied at room temperature in the spectral range of 450 to
800 nm. A dominant peak located at 577 nm and a prominent shoulder at 619 nm
are observed. Another shoulder located at 685 nm is observed at high
concentration and after additional treatment (heat, sonification) only.
Equilibrium atomic geometries and optical absorption of PTV conjugated polymers
have also been studied by first principles density functional theory (DFT). For
PTV in solvent, the theoretical calculations predict two equilibrium geometries
with different interchain distances. By comparative analysis of the
experimental and theoretical data, it is demonstrated that the new measured
long-wavelength optical absorption shoulder is consistent with new optical
absorption peak predicted for most energetically favorable PTV phase in the
solvent. This shoulder is interpreted as a direct indication of increased
interchain interaction in the solvent which has caused additional electronic
energy structure transformations.

"The Luzhin Defence" is, in the foreground, a story of an idiosyncratic chess savant (Turturro) who becomes consumed by the game and, in the background via flashbacks, his boyhood life and the forces which created the man he has become. Factor in good and evil in the forms of his his love interest (Watson) and former "mentor" (Wilson) respectively and you have a plaintive drama laced with poignant and delicately humorous moments mingled with the rich scenic beauty of Italy's Lake Como and the intensity of high chess play. An excellent film for those into period dramas, the auteur's euphemistic chess play metaphor for orgasmic delight is an indication of the subtle wit behind the film.

We obtain asymptotic formulas for eigenvalues and eigenfunctions of the
operator generated by a system of ordinary differential equations with summable
coefficients and periodic or antiperiodic boundary conditions. Then using these
asymptotic formulas, we find necessary and sufficient conditions on the
coefficients for which the system of eigenfunctions and associated functions of
the operator under consideration forms a Riesz basis.

The UKIDSS Galactic Plane Survey (GPS) is one of the five near infrared
Public Legacy Surveys that are being undertaken by the UKIDSS consortium, using
the Wide Field Camera on the United Kingdom Infrared Telescope. It is surveying
1868 sq.deg. of the northern and equatorial Galactic plane at Galactic
latitudes -5<b<5 in the J, H and K filters and a ~200 sq.deg. area of the
Taurus-Auriga-Perseus molecular cloud complex in these three filters and the
2.12 um (1-0) H_2 filter. It will provide data on ~2 billion sources. Here we
describe the properties of the dataset and provide a user's guide for its
exploitation. We also present brief Demonstration Science results from DR2 and
from the Science Verification programme. These results illustrate how GPS data
will frequently be combined with data taken in other wavebands to produce
scientific results. The Demonstration Science includes studies of: (i) the star
formation region G28.983-0.603, cross matching with Spitzer-GLIMPSE data to
identify YSOs; (ii) the M17 nebula; (iii) H_2 emission in the rho Ophiuchi dark
cloud; (iv) X-ray sources in the Galactic Centre; (v) external galaxies in the
Zone of Avoidance; (vi) IPHAS-GPS optical-infrared spectrophotometric typing.

We offer a platform for database consultations and/or biomedical images
exchanges, adapted to the low rate wireless transmission, and intended for
general practitioners or specialists. The goal can be preventive, diagnostic
and therapeutic. it Concerns specialties such as radiology, ultrasound, the
anatomical pathology or endoscopy. The main features required in such a context
are to adjust the data compression of both the specific needs of telemedicine
and limited capabilities of wireless communication networks. We present our
approach in which we have set out criteria on Biomedical images quality,
compressed by the wavelet method to retain all the necessary information for an
accurate diagnosis, and determined the characteristics of a wireless network
with minimal performances for the transmission of these images within
constraints related to the modality and the data flow, in this case Wifi based
on the IEEE 802.11 standard. Our results will assess the capacity of this
standard in terms of speed, to transmit images at a rate of 10 frames per
second. It will be necessary to quantify the amount of information to add to
the image datas to enable a transmission in good conditions and the appropriate
modus operandi.

The two parts don’t fit
Surprisingly perfect size for two six month rabbits. But the top part does NOT fit with the bottom litter pan - there is a loose gap in between which is okay for rabbit litter which is paper-ish, but I can see why it’s not good for cat litter sand

A new mechanism of spin structure-driven anomalous Hall effect (AHE) in
tilted ferromagnetic metals is proposed by taking account of the d-orbital
degree of freedom. We find that a conduction electron acquires a Berry phase
due to the complex d-orbital wavefunction, in the presence of non-collinear
spin structure and the spin orbit interaction. The AHE driven by this
orbital-derived Berry phase is much larger than the AHE induced by spin
chirality, and it naturally explains the salient features of spin
structure-driven AHE in pyrochlore Nd$_2$Mo$_2$O$_7$. Since the proposed AHE
can occur even for coplanar spin orders ($M_z=0$), it is expected to emerge in
other interesting geometrically frustrated systems.

Countless Historical & cultural mistakes 0/10<br /><br />(1) A Jewish guy named OMAR!!! Hahahaha (2) Brilliant detective was taking out by the least intelligent guy in the movie! (3) Jewish suicide bombers!! That was funny. (4) Hitler and his top guns went to watch a movie downtown Paris!!! With two guards at the door. !! shoot me. (5) Brad Pitt overacted and it was painful to watch him. (6) Mr. QT is re-writing history, "Hitler was killed in a theatre
really!" the funny thing about this is that people "and I mean stupid people" will actually believe this plot. <br /><br />And finally can any one tell me, how this movie made it to the top 250 movies of all time!!! Shame shame shame, still wondering how can anyone like this movie.

Thermal imaging-based physiological and affective computing is an emerging
research area enabling technologies to monitor our bodily functions and
understand psychological and affective needs in a contactless manner. However,
up to recently, research has been mainly carried out in very controlled lab
settings. As small size and even low-cost versions of thermal video cameras
have started to appear on the market, mobile thermal imaging is opening its
door to ubiquitous and real-world applications. Here we review the literature
on the use of thermal imaging to track changes in physiological cues relevant
to affective computing and the technological requirements set so far. In doing
so, we aim to establish computational and methodological pipelines from thermal
images of the human skin to affective states and outline the research
opportunities and challenges to be tackled to make ubiquitous real-life thermal
imaging-based affect monitoring a possibility.

Nickelodeon has gone down the toilet. They have kids saying things like "Oh my God!" and "We're screwed"<br /><br />This show promotes hate for people who aren't good looking, or aren't in the in crowd. It say that sexual promiscuity is alright, by having girls slobbering over shirtless boys. Not to mention the overweight boy who takes off his shirt. The main characters basically shun anyone out of the ordinary. Carly's friend Sam, who may be a lesbian, beats the snot out of anybody that crosses her path, which says it's alright to be a b**ch. This show has so much negativity in it that nobody should watch it! I give it a 0 out of 10!!!

You don't understand how logic and burdens of proof work.
Just because something may *possibly, remotely* be true, does not establish that it is. More importantly, the burden of establishing a claim is on the proponent to prove it, not the other party to disprove it.
Is it *possible* Trump Tower was wiretapped? Sure. But it's also *possible* the Russians infiltrated the 2016 election to hand Vulgar Talking Yam the presidency.

Claudius Moore, a seasoned technology executive who joined American Family Care (AFC) earlier this year, has been named the healthcare network’s new Chief Information Officer. Over the last 15 years, Moore has mastered methods to leverage technology to drive revenue and reduce costs for healthcare systems, while also creating a high-quality, efficient experience for patients.
Moore leads AFC’s information technology division, providing support and maintenance of existing systems while developing new technology solutions for the entire healthcare network. American Family Care is headquartered in Birmingham, Alabama, with more than 200 clinics across the nation, in more than 25 states.
“We’re thrilled to promote Claudius to the Chief Information Officer position,” said D. Bruce Irwin, M.D., CEO and founder of American Family Care. “In a very short of amount time, he has applied his extensive knowledge of technology management and his background in healthcare to advance our daily operations. His work enables AFC medical providers to stay ahead of the competition by providing quality, affordable and accessible healthcare.”
Moore has a dual master’s degree in information technology management and business administration from the University of Maryland and a bachelor’s degree in public administration from the University of Sierra Leone. In addition, he holds a graduate certificate in computer information science from The Catholic University of America and he is a Microsoft certified system administrator (MCSA).
“I’m honored to receive this promotion. It is very exciting to guide AFC through the many twists and turns of technology,” said Claudius Moore, Chief Information Officer at AFC. “My passion for medicine goes back to my first hospital job as an orderly; when I escorted heart patients to surgery. They shared their fears about their operations with me, and I comforted them. I realized healthcare was my passion.”
Previously, Moore served as Chief Information Officer of South Bend Clinic, in South Bend, Indiana, a regional hospital system, Vice President of Information Services at Physicians Hospital System in Mishawaka, Indiana, and Director of Information and Revenue Systems at Howard University Hospital in Washington, DC.
“The role of information technology in healthcare is always evolving,” Moore says. “At AFC, we are constantly working to make it easy for patients to get access to care. Not only to make an appointment through our website; but also to log in and see results, medications and insight about their care. We are providing more than urgent care. We are engaging with the patient and sharing vital details. The goal is to help them maintain a healthy lifestyle.”
All AFC clinics are designed, equipped and staffed to provide accessible primary care, urgent care and minor emergency treatment. Each clinic features a high-tech approach, including digital x-rays, on-site lab testing, state-of-the-art diagnostics and electronic medical records.

Alaska's Fiscal Crisis will be staunchly maintained by the same Republican coterie that deliberately engineered it. Some realists saw it coming as the catastrophic economic policy it turned out to be -- violating all the commonsense rules of financial risk management, and ethical economic policy.
How else could revenues sufficient to fund civil society be expected to continue from a single source which is nonrenewable, unsustainable, and responsible for triggering the climate tipping point of return?

Somewhere, buried very deep inside this film is a half-way decent movie trying to get out. The only traces are a few early scenes in Los Angeles (in a bar and a graveyard) and thereafter a couple of pieces of production design. Like I say, buried very deep. One of the biggest challenges faced by movies involving the supernatural is how to have characters react believably in unbelievable situations. Annie Mcenroe's reaction to being told that her sister (presumably Dee Wallace from the first movie) is (was?) a werewolf is, if I recall, along the lines of; "Oh! Really?". Not one of the better responses to said challenge. The non sequitirs continue as the story moves to Trannsylvania in search of Stirba the (apparently self-appointed) "Queen of the Werewolves". As Stirba, Sybil Danning is the two best things in the movie. Yes, even better than the werewolf group-sex scene, Reb Brown's acting, and the oddly simian-looking werewolf suits. The end credits have assumed minor legend status and are available in all their glory (at least until the censor finds them) on Youtube. Check them out to see why and remember, the whole film makes about the same amount of sense. If you happen to catch this on US television the credits have been re-edited to replace the endlessly repeated shot of Danning ripping off her top with another endlessly repeated shot of her ripping open a cloak only this time she has some kind of top on underneath. It's a sort of absurdity, cherry-on-top moment which defies satire.

We consider the geodesic motion on the symmetric moduli spaces that arise
after timelike and spacelike reductions of supergravity theories. The geodesics
correspond to timelike respectively spacelike $p$-brane solutions when they are
lifted over a $p$-dimensional flat space. In particular, we consider the
problem of constructing \emph{the minimal generating solution}: A geodesic with
the minimal number of free parameters such that all other geodesics are
generated through isometries. We give an intrinsic characterization of this
solution in a wide class of orbits for various supergravities in different
dimensions. We apply our method to three cases: (i) Einstein vacuum solutions,
(ii) extreme and non-extreme D=4 black holes in N=8 supergravity and their
relation to N=2 STU black holes and (iii) Euclidean wormholes in $D\geq 3$. In
case (iii) we present an easy and general criterium for the existence of
regular wormholes for a given scalar coset.

This paper presents a recursive system identification method for
multi-degree-of-freedom (MDoF) structures with tuned mass dampers (TMDs)
considering abrupt stiffness changes in case of sudden events, such as
earthquakes. Due to supplementary non-classical damping of the TMDs, the system
identification of MDoF+TMD systems disposes a challenge, in particular, in case
of sudden events. This identification methods may be helpful for structural
health monitoring of MDoF structures controlled by TMDs. A new adaptation
formulation of the unscented Kalman filter allows the identification method to
track abrupt stiffness changes. The paper, firstly, describes the theoretical
background of the proposed system identification method and afterwards presents
three parametric studies regarding the performance of the method. The first
study shows the augmented state identification by the presented system
identification method applied on a MDoF+TMD system. In this study, the abrupt
stiffness changes of the system are successfully detected and localized under
earthquake, impulse and white noise excitations. The second study investigates
the effects of the state covariance and its relevance for the system
identification of MDoF+TMD systems. The results of this study show the
necessity of an adaptive definition of the state covariance as applied in the
proposed method. The third study investigates the effects of modeling on the
performance of the identification method. Mathematical models with
discretization of different orders of convergence and system noise levels are
studied. The results show that, in particular, MDoF+TMD systems require higher
order mathematical models for an accurate identification of abrupt changes.

How can you make a joke about Mafia? It is not the kind of subject to laugh at! A near movie cannot make me laugh, because I am comparing it to Jane Austen's Mafia!. Mafia! wasn't a good movie but Hoods is really worse! In Mafia!, there were some good jokes but in this one there are maybe two or three...that make you smile. Not too bad actors but very bad scenario!! We sure prefer something serious like The Godfather. I give it * out of *****.

Well, if he is win, win, win, then maybe that will be good - he will persist until he does get a win, because he does not accept failure.
What we have now has some very serious problems, and I think it is rotten at its core.
Maybe it should be returned to the states.
That is how Canada's system was successfully started (starting with the provence of Saskatchewan, and subsequently encouraged by the Conservative government)
It is still a system of provincial plans.
And without the individual mandate which I think is pure evil - basically a tax on being alive.

Dynamical electro-weak symmetry breaking is an appealing, strongly-coupled
alternative to the weakly-coupled models based on an elementary scalar field
developing a vacuum expectation value. In the first two sections of this set of
lectures, I summarize the arguments, based on low-energy phenomenology,
supporting walking technicolor as a realistic realization of this idea. This
pedagogical introduction to walking technicolor, and more generally to the
physics of extensions of the standard model, makes extensive use of effective
field theory arguments, symmetries and counting rules. The strongly-coupled
nature of the underlying interactions, and the peculiar quasi-conformal
behavior of the theory, require to use non-perturbative methods in order to
address many fundamental questions within this framework. The recent
development of gauge/gravity dualities provides an ideal set of such
non-perturbative instruments. The remaining two sections illustrate the
potential of these techniques with two technical examples, one within the
bottom-up phenomenological approach to holography in five-dimensions, the other
within a more systematic top-down construction derived from ten-dimensional
type-IIB supergravity.

Recent coding strategies for deterministic and noisy relay networks are
related to the pipelining of block Markov encoding. For deterministic networks,
it is shown that pipelined encoding improves encoding delay, as opposed to
end-to-end delay. For noisy networks, it is observed that decode-and-forward
exhibits good rate scaling when the signal-to-noise ratio (SNR) increases.

The purpose of this thesis is to give a formal definition of quantum
Kolmogorov complexity (QC), and rigorous mathematical proofs of its basic
properties. The definition used here is similar to that by Berthiaume, van Dam,
and Laplante. It defines the QC of some indeterminate-length qubit string \rho
as the minimum base length of any quantum input which makes a quantum Turing
machine (QTM) halt and output \rho, up to some error tolerance.
First, we prove that there is a QTM which is universal in the sense of input
base length. Furthermore, we show several general properties of QTMs, including
a result on mutually orthogonal ``halting spaces'', and a way to transform
every almost-halting input into a deterministically-halting input by adding at
most a constant number of qubits.
Afterwards, we apply these results to QC. In particular, we show that QC is
invariant, incompressible, agrees with classical Kolmogorov complexity for
classical strings, and is closely related to von Neumann entropy for ergodic
quantum information sources.

We demonstrate the ability to measure precise stellar barycentric radial
velocities with the dispersed fixed-delay interferometer technique using the
Exoplanet Tracker (ET), an instrument primarily designed for precision
differential Doppler velocity measurements using this technique. Our
barycentric radial velocities, derived from observations taken at the KPNO 2.1
meter telescope, differ from those of Nidever et al. by 0.047 km/s (rms) when
simultaneous iodine calibration is used, and by 0.120 km/s (rms) without
simultaneous iodine calibration. Our results effectively show that a Michelson
interferometer coupled to a spectrograph allows precise measurements of
barycentric radial velocities even at a modest spectral resolution of R ~ 5100.
A multi-object version of the ET instrument capable of observing ~500 stars per
night is being used at the Sloan 2.5 m telescope at Apache Point Observatory
for the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS),
a wide-field radial velocity survey for extrasolar planets around TYCHO-2 stars
in the magnitude range 7.6<V<12. In addition to precise differential
velocities, this survey will also yield precise barycentric radial velocities
for many thousands of stars using the data analysis techniques reported here.
Such a large kinematic survey at high velocity precision will be useful in
identifying the signature of accretion events in the Milky Way and
understanding local stellar kinematics in addition to discovering exoplanets,
brown dwarfs and spectroscopic binaries.

OK, I am not a professional movie critic but come on...a true story!!!!<br /><br />They are tunneling under another store to get underneath the bank and stumble across a tomb. At tomb with a passageway which goes directly under the bank.<br /><br />OK, I'll play along.<br /><br />But then they get into the bank and decide to go to sleep. Yeah!!! I am sure with all the adrenaline pumping through them they are going to just fall asleep. <br /><br />This blows the whole picture!!!! How lame!!!!!<br /><br />Glad I didn't have to pay to watch this one.

Preventing eutrophication of inland freshwater ecosystems requires quantifying the phosphorus (P) content of the streams and rivers that feed them. Typical methods for measuring P assess soluble reactive P (SRP) or total P (TP) and require expensive analytical techniques that produce hazardous waste. Here we present a novel method for measuring the more relevant bioavailable P (BAP); this assay utilizes the growth of familiar bakers yeast, avoids production of hazardous waste, and reduces cost relative to measurements of SRP and TP. The yeast BAP (yBAP) assay takes advantage of the observation that yeast density at saturating growth increases linearly with provided P. We show that this relationship can be used to measure P in freshwater in concentration ranges relevant to eutrophication. In addition, we measured yBAP in water containing known amounts of fertilizer and in samples from agricultural waterways. We observed that the majority of yBAP values were between those obtained from standard SRP and TP measurements, demonstrating that the assay is compatible with real-world settings. The cost-effective and nonhazardous nature of the yeast-based assay suggests that it could have utility in a range of settings, offering added insight to identify water systems at risk of eutrophication from excess phosphorus.

We calculate the linear response conductance of electrons in a Luttinger
liquid with arbitrary interaction g_2, and subject to a potential barrier of
arbitrary strength, as a function of temperature. We map the Hamiltonian in the
basis of scattering states into an effective low energy Hamiltonian in current
algebra form. First the renormalization group (RG) equation for weak
interaction is derived in the current operator language both using the operator
product expansion and the equation of motion method. To access the strong
coupling regime, two methods of deducing the RG equation from perturbation
theory, based on the scaling hypothesis and on the Callan-Symanzik formulation,
are discussed. The important role of scale independent terms is emphasized. The
latter depend on the regulaization scheme used (length versus temperature
cutoff). Analyzing the perturbation theory in the fermionic representation, the
diagrams contributing to the renormalization group beta-function are
identified. A universal part of the beta-function is given by a ladder series
and summed to all orders in g_2. First non-universal corrections beyond the
ladder series are discussed and are shown to differ from the exact solutions
obtained within conformal field theory which use a different regularization
scheme. The RG equation for the temperature dependent conductance is solved
analytically. Our result agrees with known limiting cases.

There is an axiomatic treatment of Morley rank in groups, due to Borovik and
Poizat. These axioms form the basis of the algebraic treatment of groups of
finite Morley rank which is common today. There are, however, ranked
structures, i.e. structures on which a Borovik-Poizat rank function is defined,
which are not $\aleph_0$-stable. Poizat raised the issue of the relationship
between this notion of rank and stability theory in the following terms: ``un
groupe de Borovik est une structure stable, alors qu'un univers rang\'e n'a
aucune raison de l'\^etre ...''. Nonetheless, we show that a ranked structure
is superstable.

Whoops, autospell error? I think the clown-beast meant to say "total indictment." And no, it isn't about Russia. It's about a criminal conspiracy to subvert democracy itself with the domestic deployment of PsyOps and other military techniques to secure dark and illegitimate ends, and of which Robert Mercer and Steve Bannon appear to also be integral parts.

We explore the use of the color-log(n) plane (where n is the global Sersic
index) as a tool for subdividing the high redshift galaxy population in a
physically-motivated manner. Using a series of volume-limited samples out to
z=1.5 in the Hubble Ultra Deep Field (UDF) we confirm the correlation between
color-log(n) plane position and visual morphology observed locally and in other
high redshift studies in the color and/or structure domain. Via comparison to a
low redshift sample from the Millennium Galaxy Catalogue we quantify evolution
by color-log(n) type, accounting separately for the specific selection and
measurement biases against each. Specifically, we measure decreases in B-band
surface brightness of 1.57 +/- 0.22 mag/sq.arcsec and 1.65 +/- 0.22
mag/sq.arcsec for `blue, diffuse' and `red, compact' galaxies respectively
between redshift unity and the present day.

We study the limit of quasilocal mass defined in [4] and [5] for a family of
spacelike 2-surfaces in spacetime. In particular, we show the limit coincides
with the ADM mass at spatial infinity. The limit for coordinate spheres of a
boosted slice of the Schwarzchild solution is computed explicitly and shown to
give the expected energy-momentum four vector.

Propositional Typicality Logic (PTL) is a recently proposed logic, obtained
by enriching classical propositional logic with a typicality operator capturing
the most typical (alias normal or conventional) situations in which a given
sentence holds. The semantics of PTL is in terms of ranked models as studied in
the well-known KLM approach to preferential reasoning and therefore KLM-style
rational consequence relations can be embedded in PTL. In spite of the
non-monotonic features introduced by the semantics adopted for the typicality
operator, the obvious Tarskian definition of entailment for PTL remains
monotonic and is therefore not appropriate in many contexts. Our first
important result is an impossibility theorem showing that a set of proposed
postulates that at first all seem appropriate for a notion of entailment with
regard to typicality cannot be satisfied simultaneously. Closer inspection
reveals that this result is best interpreted as an argument for advocating the
development of more than one type of PTL entailment. In the spirit of this
interpretation, we investigate three different (semantic) versions of
entailment for PTL, each one based on the definition of rational closure as
introduced by Lehmann and Magidor for KLM-style conditionals, and constructed
using different notions of minimality.

We present a study of deep levels in CdZnTeSe radiation-detection materials.
The approach relies on electrical methods that combine time and temperature
evolution of the electric field and electric current after switching on the
bias voltage. We also applied two optical methods to study the deep levels. The
first method utilizes the temperature and temporal analysis of the
electric-field evolution after switching off an additional light illuminating
the sample at a wavelength of 940 nm. The second method involved measuring of
the electric-field spectral dependence during near infrared illumination. We
compare the results with those obtained with high-quality CdZnTe detector-grade
material. We conclude that the introduction of Se into the lattice leads to a
shift of the second ionization level of the Cd vacancy towards the conduction
band, as predicted recently by first-principles calculations based on screened
hybrid functionals.

This paper presents a decentralized relay selection protocol for a dense
wireless network and describes channel feedback strategies that improve its
performance. The proposed selection protocol supports hybrid
automatic-repeat-request transmission where relays forward parity information
to the destination in the event of a decoding error. Channel feedback is
employed for refining the relay selection process and for selecting an
appropriate transmission mode in a proposed adaptive modulation transmission
framework. An approximation of the throughput of the proposed adaptive
modulation strategy is presented, and the dependence of the throughput on
system parameters such as the relay contention probability and the adaptive
modulation switching point is illustrated via maximization of this
approximation. Simulations show that the throughput of the proposed selection
strategy is comparable to that yielded by a centralized selection approach that
relies on geographic information.

A novel use of Majorana geometric representation brings out distinct
entanglement families of permutation symmetric states of qubits. The
paradigmatic W and GHZ (Greenberger-Horne-Zeilinger) states of three qubits
respectively contain two and three independent Majorana spinors. Another unique
state with three distinct Majorana spinors -- constructed through a permutation
symmetric superposition of two up qubits and one down qubit (W state) and its
obverse state Wbar) exhibits genuine three-party entanglement, which is robust
under loss of a qubit. While the GHZ state has irreducible correlations and
cannot be determined from its parts, we show here that the correlation
information of the W-superposition state is imprinted uniquely in its two party
reduced states. This striking example sheds light on the contrasting
irreducibility features of interconvertible states.

I admit to liking a lot of the so-called "frat-pack" movies. No matter how bad they are, I can find something to like about Ben Stiller or Owen Wilson or Vince Vaughn or Will Ferrell or Jack Black. But "Envy" just left me about as cold as the white horse that Ben disposed of. This time, it's Ben and Jack Black as a couple of nutty neighbors, one of whom (Black) discovers a aerosol spray to make animal poop disappear and becomes incredibly wealthy while the other (Stiller) writhes in envy. That's supposedly the plot, but then it veers off in other directions that don't really make much sense.<br /><br />I guess the 'Vapoorize' thing is sort of amusing at first. The problem is, they try to sustain the gag for the whole picture (Black has a license plate that reads 'Caca King') and it gets fairly tiresome. But even Ben and Jack are used poorly; the energy level for both of their performances seems significantly dialed down. The two best performances by far are Rachel Weisz and Chris Walken. Walken's neo-hippie-dippie guy is so offbeat and so well-modulated a performance that it really never suggests any of Walken's other familiar nutcase characters. It's completely unique, yet comes across as unmistakably Walken. And Weisz is about the best actress in the business that nobody knows about. Even with limited screen time, she still dominates every scene she's in.<br /><br />The whole crux of the so-called drama is that Ben, in a jealous drunken stupor, accidentally shoots Jack's prize white stallion, and then goes to ridiculous lengths to cover it up, fearing his best friend will find out and cut him dead. But the plot twist isn't believable because there's nothing about Jack's character to indicate that he would do such a thing. He plays such a sweet guy that it renders the whole excruciating horse chase null and void. You discount it completely. It's all filler. And what's the point of the out-of-control merry-go-round, except that Barry Levinson wants us to know that he's seen "Strangers on a Train"? The screenplay is painfully bad and the acting of the two leads poorly directed. Someone with Levinson's track record should know better. Maybe someone will invent something to make this film disappear. Oh, wait, they already have.

MOG is a fully relativistic modified theory of gravity based on an action
principle. The MOG field equations are exactly solvable numerically in two
important cases. In the spherically symmetric, static case of a gravitating
mass, the equations also admit an approximate solution that closely resembles
the Reissner-Nordstrom metric. Furthermore, for weak gravitational fields, a
Yukawa-type modification to the Newtonian acceleration law can be obtained,
which can be used to model a range of astronomical observations. Without
nonbaryonic dark matter, MOG provides good agreement with the data for galaxy
rotation curves, galaxy cluster masses, and gravitational lensing, while
predicting no appreciable deviation from Einstein's predictions on the scale of
the solar system. Another solution of the field equations is obtained for the
case of a a spatially homogeneous, isotropic cosmology. MOG predicts an
accelerating universe without introducing Einstein's cosmological constant; it
also predicts a CMB acoustic power spectrum and a mass power spectrum that are
consistent with observations without relying on non-baryonic dark matter.
Increased sensitivity in future observations or space-based experiments may be
sufficient to distinguish MOG from other theories, notably the LCDM "standard
model" of cosmology.

This paper studies a time-changed stochastic control problem, where the
underlying stochastic process is a L\'evy noise time-changed by an inverse
subordinator. We establish a maximum principle theory for the time-changed
stochastic control problem. We also prove the existence and uniqueness of the
corresponding time-changed backward stochastic differential equation involved
in the stochastic control problem. Some examples are provided for illustration.

Using a first-principles cluster expansion, we shed light on the solid-state
phase diagram and structure of the recently discovered high-performance
thermoelectrics, Pb-Ag-Sb-Te alloys. The observed nanoscale inhomogeneities are
shown to be coherent precipitates of ordered (Ag)m(Sb)n(Te)m+n phases, such as
AgSbTe2, all immiscible with rocksalt PbTe. The solubility is high for PbTe in
AgSbTe2 and low for (Ag,Sb)Te in PbTe (8% vs. 0.6% at 850 K). The differences
in the phonon spectra of PbTe and AgSbTe2 confirm that the inhomogeneities
enhance the thermoelectric performance.

The analysis of gravitational wave data involves many model selection
problems. The most important example is the detection problem of selecting
between the data being consistent with instrument noise alone, or instrument
noise and a gravitational wave signal. The analysis of data from ground based
gravitational wave detectors is mostly conducted using classical statistics,
and methods such as the Neyman-Pearson criteria are used for model selection.
Future space based detectors, such as the \emph{Laser Interferometer Space
Antenna} (LISA), are expected to produced rich data streams containing the
signals from many millions of sources. Determining the number of sources that
are resolvable, and the most appropriate description of each source poses a
challenging model selection problem that may best be addressed in a Bayesian
framework. An important class of LISA sources are the millions of low-mass
binary systems within our own galaxy, tens of thousands of which will be
detectable. Not only are the number of sources unknown, but so are the number
of parameters required to model the waveforms. For example, a significant
subset of the resolvable galactic binaries will exhibit orbital frequency
evolution, while a smaller number will have measurable eccentricity. In the
Bayesian approach to model selection one needs to compute the Bayes factor
between competing models. Here we explore various methods for computing Bayes
factors in the context of determining which galactic binaries have measurable
frequency evolution. The methods explored include a Reverse Jump Markov Chain
Monte Carlo (RJMCMC) algorithm, Savage-Dickie density ratios, the Schwarz-Bayes
Information Criterion (BIC), and the Laplace approximation to the model
evidence. We find good agreement between all of the approaches.

Measurements of inclusive hadron suppression and di-hadron azimuthal
correlations in ultra-relativistic nuclear collisions at RHIC have provided
important insights into jet quenching in hot QCD matter, but are limited in
their sensitivity due to well-known biases. Full jet reconstruction in
heavy-ion collisions would conceptually provide a direct measurement of the
energy of the scattered parton before energy loss, alleviating such biases and
allowing a measurement of the energy loss probability distribution in a
model-independent way from hard probes. In these proceedings we utilize recent
progress in the reconstruction of jets in the heavy ion environment and present
the first measurement of the fragmentation function from fully reconstructed
jets in heavy ion collisions. The fragmentation function measured in central
Au+Au collisions at $\sqrt{s_{_{\rm NN}}}=200$ GeV will be presented and
discussed with respect to p+p reference measurements.

The topological Hall effect (THE) and its thermoelectric counterpart, the
topological Nernst effect (TNE), are hallmarks of the skyrmion lattice phase
(SkL). We observed the giant TNE of the SkL in centrosymmetric Gd$_2$PdSi$_3$,
comparable in magnitude to the largest anomalous Nernst signals in
ferromagnets. Significant enhancement (suppression) of the THE occurs when
doping electrons (holes) to Gd$_2$PdSi$_3$. On the electron-doped side, the
topological Hall conductivity approaches the characteristic threshold $\sim
1000\,\left(\mathrm{\Omega cm}\right)^{-1}$ for the intrinsic regime. We use
the filling-controlled samples to confirm Mott's relation between TNE and THE
and discuss the importance of Gd-5d orbitals for transport in this compound.

Kramer vs. Kramer is the story of a marital breakup and the consequences of same. They can be devastating to the partners and even more so to a minor child which in this case is played by Justin Henry.<br /><br />What I really did like about Kramer vs. Kramer, it's greatest strength as a film is the way that parents Dustin Hoffman and Meryl Streep are presented to the audience as whole people with many sides to their nature. Though the film is slanted in Hoffman's direction and more about his relationship with his son, he's not presented as any kind of saint, nor is Streep a completely black villain. Hoffman's a career oriented man in the advertising game. He's pretty much ignored his wife's dreams and aspirations, still it's a big shock to him when Streep says the love's no longer there and she wants out. She also wants out of being a mother, at least for a while.<br /><br />Hoffman and Henry make do the best they can. The pressure of being both parents causes Hoffman to lose his job and he has to take a lower paying one in another agency. At that point after over a year, Streep decides she wants custody.<br /><br />Both parents make compelling witnesses and state their case beautifully, but in these situations, the tie is always broken in favor of the mother.<br /><br />Dustin Hoffman and Meryl Streep won their first of two Oscars respectively for this film, her in the Supporting Actress category. I'm not sure how these things are decided, Streep does get less screen time than Hoffman if that's the determining factor. The film does focus on Hoffman's relationship with his son and his evolving realization that he has his share of the blame for the marriage failure. As for Meryl it's a Hob's choice for her as it is for many women, to balance a career and motherhood. The conflict in her psyche registers for all to see on the screen.<br /><br />Dustin Hoffman may have won that Oscar partly for the same reason that Spencer Tracy picked up his first, by performing the impossible task of not letting a scene stealing child steal the film. Children with their lack of inhibitions are natural actors and Henry is great because he comes over as a real kid, not a Hollywood kid. I wonder if Hoffman saw Captains Courageous and saw how Spencer Tracy dealt with Freddie Bartholomew. Dustin could have done a lot worse than channel Spencer Tracy in his performance.<br /><br />Kramer vs. Kramer also won Oscars for Best Picture, Best Director for Robert Benton and Best Adapted Screenplay. It's an intelligent and compelling drama about adults falling out of love and trying to deal as best they can with it for themselves and their child. Don't miss it if ever broadcast.

Let a particle move in the flat space-time under the action of the electric
potential. If it decays to two fragments, the energy of debris can be larger
than the original energy and, moreover, the efficiency of such a process can be
unbounded. This effect can be considered as a limit of the Denardo-Ruffini
process near the Reissner-Nordstr\"{o}m black hole when the gravitational
constant and/or black hole mass tend to zero. There are scenarios in which the
energy of debris at infinity is much larger than the initial one. Comparison
with other close but distinct effects is discussed.

We introduce a new graph polynomial that encodes interesting properties of
graphs, for example, the number of matchings and the number of perfect
matchings. Most importantly, for bipartite graphs the polynomial encodes the
number of independent sets (#BIS).
We analyze the complexity of exact evaluation of the polynomial at rational
points and show that for most points exact evaluation is #P-hard (assuming the
generalized Riemann hypothesis) and for the rest of the points exact evaluation
is trivial.
We conjecture that a natural Markov chain can be used to approximately
evaluate the polynomial for a range of parameters. The conjecture, if true,
would imply an approximate counting algorithm for #BIS, a problem shown, by
[Dyer et al. 2004], to be complete (with respect to, so called, AP-reductions)
for a rich logically defined sub-class of #P. We give a mild support for our
conjecture by proving that the Markov chain is rapidly mixing on trees. As a
by-product we show that the "single bond flip" Markov chain for the random
cluster model is rapidly mixing on constant tree-width graphs.

Post-click conversion rate (CVR) estimation is a critical task in e-commerce
recommender systems. This task is deemed quite challenging under the industrial
setting with two major issues: 1) selection bias caused by user self-selection,
and 2) data sparsity due to the rare click events. A successful conversion
typically has the following sequential events: "exposure -> click ->
conversion". Conventional CVR estimators are trained in the click space, but
the inference is done in the entire exposure space. They fail to account for
the causes of the missing data and treat them as missing at random. Hence,
their estimations are highly likely to deviate from the real values by large.
In addition, the data sparsity issue can also handicap many industrial CVR
estimators which usually have large parameter spaces.
In this paper, we propose two principled, efficient and highly effective CVR
estimators for industrial CVR estimation, namely, Multi-IPW and Multi-DR. The
proposed models approach the CVR estimation from a causal perspective and
account for the causes of missing not at random. In addition, our methods are
based on the multi-task learning framework and mitigate the data sparsity
issue. Extensive experiments on industrial-level datasets show that our methods
outperform the state-of-the-art CVR models.

In the mid-1990s, Stanley and Stembridge conjectured that the chromatic
symmetric functions of claw-free co-comparability (also called incomparability)
graphs were e-positive. The quest for the proof of this conjecture has led to
an examination of other, related graph classes. In 2013 Guay-Paquet proved that
if unit interval graphs are e-positive, that implies claw-free incomparability
graphs are as well. Inspired by this approach, we consider a related case and
prove that unit interval graphs whose complement is also a unit interval graph
are e-positive. We introduce the concept of strongly $e$-positive to denote a
graph whose induced subgraphs are all e-positive, and conjecture that a graph
is strongly e-positive if and only if it is (claw, net)-free.

Semimartingale reflecting Brownian motions (SRBMs) living in the closures of
domains with piecewise smooth boundaries are of interest in applied probability
because of their role as heavy traffic approximations for some stochastic
networks. In this paper, assuming certain conditions on the domains and
directions of reflection, a perturbation result, or invariance principle, for
SRBMs is proved. This provides sufficient conditions for a process that
satisfies the definition of an SRBM, except for small random perturbations in
the defining conditions, to be close in distribution to an SRBM. A crucial
ingredient in the proof of this result is an oscillation inequality for
solutions of a perturbed Skorokhod problem. We use the invariance principle to
show weak existence of SRBMs under mild conditions. We also use the invariance
principle, in conjunction with known uniqueness results for SRBMs, to give some
sufficient conditions for validating approximations involving (i) SRBMs in
convex polyhedrons with a constant reflection vector field on each face of the
polyhedron, and (ii) SRBMs in bounded domains with piecewise smooth boundaries
and possibly nonconstant reflection vector fields on the boundary surfaces.

We study non Hermitian quantum systems in noncommutative space as well as a
\cal{PT}-symmetric deformation of this space. Specifically, a
\mathcal{PT}-symmetric harmonic oscillator together with iC(x_1+x_2)
interaction is discussed in this space and solutions are obtained. It is shown
that in the \cal{PT} deformed noncommutative space the Hamiltonian may or may
not possess real eigenvalues depending on the choice of the noncommutative
parameters. However, it is shown that in standard noncommutative space, the
iC(x_1+x_2) interaction generates only real eigenvalues despite the fact that
the Hamiltonian is not \mathcal{PT}-symmetric. A complex interacting
anisotropic oscillator system has also been discussed.

The alkali-trihalogeno-germanates AGeX$_3$ with A a large single positive ion
such as Rb, Cs, or organic radicals such as methyl ammonium (MA), and X a
halogen (I, Br, Cl, F) along with the corresponding stannates (ASnX$_3$) and
plumbates (APbX$_3$) exhibit a large variety of crystal structures, some of
which are of the perovskite type. These materials, better known as "halide
perovskites'' have recently gained worldwide attention as promising
photovoltaic and more broadly opto-electronic materials. But their stability
problems relative to the non-perovskite phases is a major issue. Here we show
that the phase relations in these materials can be understood in terms of the
relative orientation of the GeX$_3$ tetrahedral units, which is ferroelectric
in the perovskite phase but antiferroelectric in the competing phases. This
suggests that an applied electric field could be used to stabilize the desired
phases and trigger a phase transition between two phases of the material with
widely different optical and electronic properties.

Weak measurements offer new insights into the behavior of quantum systems.
Combined with post-selection, quantum mechanics predicts a range of new
experimentally testable phenomena. In this paper I consider weak measurements
performed on time-dependent pre- and post-selected ensembles, with emphasis on
the decay of excited states. The results show that the standard exponential
decay law is a limiting case of a more general law that depends on both the
time of post-selection and the choice of final state. The generalized law is
illustrated for two interesting choices of post-selection.

Accretion and star formation (SF) rates in low redshift SDSS type-II active
galactic nuclei (AGN) are critically evaluated. Comparison with photoionization
models indicates that bolometric luminosity (Lbol) estimates based on L(oiii
5007A) severely underestimate Lbol in low ionization sources such as LINERs. An
alternative method based on L(hb) is less sensitive to ionization level and a
novel method, based on a combination of L(oiii 5007A) and L(oi 6300A), is
erhaps the best. Using this method I show that low ionization AGN are accreting
faster than assumed until now. Significant related other findings are: 1. Any
type-II AGN property related to the black hole (BH) mass is more reliably
obtained by removing blue galaxies from the sample. 2. Seyfert 2s and LINER 2s
form a continuous sequence of L/Ledd with no indication for a change in
accretion mechanism, or mode of mass supply. There are very few, if any, LINERs
in all type-I samples which results in a much arrower L/Ledd distribution
compared with type-II samples. 3. There is a strong correlation between SF
luminosity, Lsf, and Lbol over more than five orders of magnitude in
luminosity. This leads to a simple relationship between bulge and BH growth
rates, g(bulge)/g(BH) propto Lbol^(-0.2), where g(bulge)/g(BH) = 115 for
Lbol=10^42 erg/sec. Seyfert 2s and LINER 2s follow the same Lsf-Lbol
correlation for all sources with a stellar age indicator, D4000, smaller than
1.8. This suggests that a similar fraction of SF gas finds its way to the
center in all AGN. 4. Lbol, Lsf, L/Ledd and the specific SF rate follow D4000
in a similar way.

Interpretable machine learning has gained much attention recently. Briefness
and comprehensiveness are necessary in order to provide a large amount of
information concisely when explaining a black-box decision system. However,
existing interpretable machine learning methods fail to consider briefness and
comprehensiveness simultaneously, leading to redundant explanations. We propose
the variational information bottleneck for interpretation, VIBI, a
system-agnostic interpretable method that provides a brief but comprehensive
explanation. VIBI adopts an information theoretic principle, information
bottleneck principle, as a criterion for finding such explanations. For each
instance, VIBI selects key features that are maximally compressed about an
input (briefness), and informative about a decision made by a black-box system
on that input (comprehensive). We evaluate VIBI on three datasets and compare
with state-of-the-art interpretable machine learning methods in terms of both
interpretability and fidelity evaluated by human and quantitative metrics

Latent Dirichlet Allocation (LDA) model is a famous model in the topic model
field, it has been studied for years due to its extensive application value in
industry and academia. However, the mathematical derivation of LDA model is
challenging and difficult, which makes it difficult for the beginners to learn.
To help the beginners in learning LDA, this book analyzes the mathematical
derivation of LDA in detail, and it also introduces all the knowledge
background to make it easy for beginners to understand. Thus, this book
contains the author's unique insights. It should be noted that this book is
written in Chinese.

The aim of this work was to investigate the perceptual relevance of the frequency following response to the syllable /da/ for speech intelligibility in noise based on age and hearing deficits. Recordings of the auditory evoked potential from young normal hearing (NH) and older individuals with both normal hearing and high-frequency (HF) hearing loss were analyzed. EFR metrics obtained in quiet and noise condition were calculated and correlated with speech reception. The envelope following responses were analyzed in terms of amplitude, latency and noise robustness. The response was first simulated to form predictions on the effect of cochlear synaptopathy and outer hair cell loss on the EFR. The experimental findings were in line with the computational predictions in the found observation that the EFR was reduced as a consequence of ageing and HF hearing loss. Both the audiogram and the speech EFR magnitude fell short in the individual prediction of SRT in stationary noise, but they accounted well for group performance. We also obtained within-group EFR latency with a cross covariance matrix. Validation of the method confirmed that speech EFR latency was predictive of click ABR Wave V peak latency. Moreover, statistical analysis not only showed that the robustness of the EFR obtained in the noise condition was dependent on the degree of high-frequency hearing loss in the older NH adults, but also dependent on the EFR magnitude in the NH younger adults. These findings provide evidence towards the important role of the EFR in speech-in-noise perception.

We analyse the feasibility of low-scale leptogenesis where the inverse seesaw
(ISS) and linear seesaw (LSS) terms are not simultaneously present. In order to
generate the necessary mass splittings, we adopt a Minimal Lepton Flavour
Violation (MLFV) hypothesis where a sterile neutrino mass degeneracy is broken
by flavour effects. We find that resonant leptogenesis is feasible in both
scenarios. However, because of a flavour alignment issue, MLFV-ISS leptogenesis
succeeds only with a highly tuned choice of Majorana masses. For MLFV-LSS, on
the other hand, a large portion of parameter space is able to generate
sufficient asymmetry. In both scenarios we find that the lightest neutrino mass
must be of order $10^{-2}\text{ eV}$ or below for successful leptogenesis. We
briefly explore implications for low-energy flavour violation experiments, in
particular $\mu \rightarrow e\,\gamma$. We find that the future MEG-II
experiment, while sensitive to MLFV in our setup, will not be sensitive to the
specific regions required for resonant leptogenesis.

I bought this for some new wrist/arm pain likely carpal tunnel related from my office job (undiagnosed but it runs in my family). The compression offers a bit of relief which is great while I’m working because the band itself allows me to move similarly to how I do when I’m not in any pain. The hand, however is so loose it doesn’t help much and my thumb is the same as before. Also, I highly recommend AGAINST sleeping with this sleeve on. I fell asleep around 11 and woke up miserable by 3 because it had rolled down my arm and cut of most of the circulation to my hand. My fingers couldn’t bend and were swollen to twice their usual size. If you need a sleeve/wrist band for pain relief at night, use one with a splint.

We report on the diffuse X-ray emissions from the Galactic center (GCDX)
observed with the X-ray Imaging Spectrometer (XIS) on board the Suzaku
satellite. The highly accurate energy calibrations and extremely low background
of the XIS provide many new facts on the GCDX. These are (1) the origin of the
6.7/7.0keV lines is collisional excitation in hot plasma, (2) new SNR and
super-bubble candidates are found, (3) most of the 6.4keV line is fluorescence
by X-rays, and (4) time variability of the 6.4keV line is found from the SgrB2
complex.

In this paper we show that by suitably tailoring the dispersion
characteristics of a Bragg reflection waveguide (BRW) mode, it is possible to
achieve efficient photon pair generation over a large pump bandwidth while
maintaining narrow signal bandwidth. The structure proposed consists of a high
index core BRW with a periodically poled GaN core and periodically stratified
cladding made up of alternate layers of $Al_{0.02}Ga_{0.98}N$ and
$Al_{0.45}Ga_{0.55}N$. Such photon-pair generators should find applications in
realizing compact and stable sources for quantum information processing.

We consider the quasi-static evolution of a brittle layer on a stiff
substrate; adhesion between layers is assumed to be elastic. Employing a
phase-field approach we obtain the quasi-static evolution as the limit of
time-discrete evolutions computed by an alternate minimization scheme. We study
the limit evolution, providing a qualitative discussion of its behaviour and a
rigorous characterization, in terms of parametrized balanced viscosity
evolutions. Further, we study the transition layer of the phase-field, in a
simplified setting, and show that it governs the spacing of cracks in the first
stages of the evolution. Numerical results show a good consistency with the
theoretical study and the local morphology of real life craquelure patterns.

Pretty
It's actually really pretty. I think for the quality though, it should be priced a little lower. The material is really cheap. Also the pants on me are a little too big (which I can understand because I am very short and thin) but the top is almost too small which is weird. I feel like I wear is without an undershirt my boob is gonna slip out the side. But again, it's really pretty. The blue is a bit darker than the picture but still gives off a great Princess Jasmine/Genderbent Genie vibe. Hope this helps!

The purpose of this paper is to describe certain CR-covariant differential
operators on a strictly pseudoconvex CR manifold $M$ as residues of the
scattering operator for the Laplacian on an ambient complex K\"{a}hler manifold
$X$ having $M$ as a `CR-infinity.' We also characterize the CR $Q$-curvature in
terms of the scattering operator. Our results parallel earlier results of
Graham and Zworski \cite{GZ:2003}, who showed that if $X$ is an asymptotically
hyperbolic manifold carrying a Poincar\'{e}-Einstein metric, the $Q$-curvature
and certain conformally covariant differential operators on the `conformal
infinity' $M$ of $X$ can be recovered from the scattering operator on $X$. The
results in this paper were announced in \cite{HPT:2006}.

Software that cannot change is condemned to atrophy: it cannot accommodate
the constant revision and re-negotiation of its business goals nor intercept
the potential of new technology. To accommodate change in such systems we have
defined an active software architecture to be: dynamic in that the structure
and cardinality of the components and interactions are not statically known;
updatable in that components can be replaced dynamically; and evolvable in that
it permits its executing specification to be changed. Here we describe the
facilities of the ArchWare architecture description language (ADL) for
specifying active architectures. The contribution of the work is the unique
combination of concepts including: a {\pi}-calculus based communication and
expression language for specifying executable architectures; hyper-code as an
underlying representation of system execution; a decomposition operator to
break up and introspect on executing systems; and structural reflection for
creating new components and binding them into running systems.

The magnetic properties of Co (<D>=15 nm, <L>=130nm) nanowires are reported.
In oxidized wires, we measure large exchange bias fields of the order of 0.1 T
below T ~ 100 K. The onset of the exchange bias, between the ferromagnetic core
and the anti-ferromagnetic CoO shell, is accompanied by a coercivity drop of
0.2 T which leads to a minimum in coercivity at $\sim100$ K. Magnetization
relaxation measurements show a temperature dependence of the magnetic viscosity
S which is consistent with a volume distribution of the CoO grains at the
surface. We propose that the superparamagnetic fluctuations of the
anti-ferromagnetic CoO shell play a key role in the flipping of the nanowire
magnetization and explain the coercivity drop. This is supported by
micromagnetic simulations. This behavior is specific to the geometry of a 1D
system which possesses a large shape anisotropy and was not previously observed
in 0D (spheres) or 2D (thin films) systems which have a high degree of symmetry
and low coercivities. This study underlines the importance of the AFM
super-paramagnetic fluctuations in the exchange bias mechanism.

Before Last Call w/ Carson Daly, my local NBC affiliate aired much more worthwhile programming after Late Night w/ Conan such as second city TV, 3rd Rock From the Sun & Carline in the City reruns, and some stand up comedy. These days there is nothing worthwhile to watch because all I get to see is Carson Daly and his awful show. He is not a comedian, he is not an actor, he does not deserve to be famous because he isn't a good speaker nor comedian.<br /><br />On his June 21st show, he tried to use an internet meme called the "Rickroll" on his show. He failed hard. That event confirms that Carson Daly is awful.

The One and the Only!<br /><br />The only really good description of the punk movement in the LA in the early 80's. Also, the definitive documentary about legendary bands like the Black Flag and the X. Mainstream Americans' repugnant views about this film are absolutely hilarious! How can music be SO diversive in a country of supposed liberty...even 20 years after...find out!<br /><br />

Alaska's marijuana system was broken from the get-go. Oregon did it right. No guarantee any of these "Growers" even know what they are doing, just that they know how to jump through bureaucratic hoops. Stepping through endless levels of government is ridiculous. Washington gave a ton of licenses to people who had no clue how to grow and saw part of their industry struggle to produce at the beginning. Lots of Washington growers were a joke. Alaska is shaping up like Washington. Oregon's industry is is thriving and behaving, and a grower can literally walk in to a store and sell their product. The licensing is easy! I want Oregon's system here.

We carry out direct numerical simulation of compressible square duct flow in
the range of bulk Mach numbers M_b = 0.2-3, and up to friction Reynolds number
Re_{\tau} = 500. The effects of flow compressibility on the secondary motions
are found to be negligible, as the typical Mach number associated with the
cross-stream flow is always less than 0.1. As in the incompressible case, we
find that the wall law for the mean streamwise velocity applies with good
approximation with respect to the nearest wall, upon suitable compressibility
transformation. The same conclusion also applies to a passive scalar field,
whereas the mean temperature does not exhibit inertial layers because of
nonuniformity of the aerodynamic heating. We further find that the same
temperature/velocity relation that holds for planar channels is applicable with
good approximation for square ducts, and develop a similar relation between
temperature and passive scalars.

Lets not forget how China took advantage of Obama with the Paris Climate Accord. China can build as many coal fired generation plants, add more cars, etc. as they want until 2030. At the same time China is selling solar panels to the USA after undercutting the American subsidized manufacturers causing many of them to go bankrupt.

In this brief note, we reconsider the problem of finding Euclidean wormhole
solutions to maximal supergravity in d dimensions. We find that such solutions
exists for all d less than or equal to 9. However, we argue that, in
toroidally-compactified string theories, these saddle points never contribute
to the path integral because of a tension with U-duality.

Measures of complex network analysis, such as vertex centrality, have the
potential to unveil existing network patterns and behaviors. They contribute to
the understanding of networks and their components by analyzing their
structural properties, which makes them useful in several computer science
domains and applications. Unfortunately, there is a large number of distinct
centrality measures and little is known about their common characteristics in
practice. By means of an empirical analysis, we aim at a clear understanding of
the main centrality measures available, unveiling their similarities and
differences in a large number of distinct social networks. Our experiments show
that the vertex centrality measures known as information, eigenvector,
subgraph, walk betweenness and betweenness can distinguish vertices in all
kinds of networks with a granularity performance at 95%, while other metrics
achieved a considerably lower result. In addition, we demonstrate that several
pairs of metrics evaluate the vertices in a very similar way, i.e. their
correlation coefficient values are above 0.7. This was unexpected, considering
that each metric presents a quite distinct theoretical and algorithmic
foundation. Our work thus contributes towards the development of a methodology
for principled network analysis and evaluation.

The Fallen Ones starts with archaeologist Matt Fletcher (Casper Van Dien) in the desert discovering the mummified remains of a 42 foot tall giant, now there's something you don't see everyday. Matt is working for property developer Morton (Robert Wagner) who wants to build a holiday resort on the land & he calls in fellow archaeologist Angela (Kristen Miller) for reasons I'm unsure of. Anyway they both try to figure out what they've got on they're hands when some of the team go missing, Morton calls in security guy Ammon (Navid Negahban) to handle the situation. Meanwhile ancient text translator the Rabbi Eli Schmidtt (Tom Bosley) translates some ancient text (as he would) & is shocked to learn of a evil prophecy in which these giants will rise up & take over the world for the Fallen One, or something like that. It's up to Matt to save the day & the whole planet...<br /><br />Written & directed by Kevin VanHook, who also has a small role in the film as the ancient warrior leader at the start, I personally thought The Fallen Ones was a terrible film & it's as simple & straight forward as that. There are so many things that are just plain bad about The Fallen Ones both on a technical & conceptual level, the script doesn't make a whole lot of sense & it doesn't really get going until the final 20 odd minutes by which time I had almost lost the will to live. The character's are awful & as clichéd as you like, the dialogue is bad as in very, very bad & the entire film is predictable, I mean it's not going to come as a surprise that Casper Van Dien is going to save the day is it? It's not a huge surprise that the mummified giant is going to come back to life either so why wait until over an hour into the film when most of the audience will be in some sort of comatose state. This is bad, very bad. You have been warned.<br /><br />Director VanHook doesn't impress, the fight scenes are absolutely awful & why dress your bad guys up in a horrible shade of purple? They look naff. To give it a bit of credit the special effects on the giant Mummy itself are actually good although there's not that many of them since he doesn't make an appearance for over an hour, there are also some normal sized Mummy's that look to have come straight from the set of The Mummy (1999), unfortunately these aren't used to any great effect & in fact are wasted as some comic relief. The mechanical Mummy was a pretty good idea but looked silly & there is no way on Earth that all those people inside could work in sync with each other to operate it, actually the more I think about the more ridiculous the idea is. Forget about any scares, tension or atmosphere & don't even think about any gore or violence because there isn't any.<br /><br />Technically The Fallen Ones isn't anything special & apart from the impressive giant Mummy effects there's little her to get excited about. The ghost CGI & water effects are terrible, it was made-for-TV & it's shows. The acting was poor, Wagner looks embarrassed & this is probably the only thing the likes of Dien & Bosley can get these days.<br /><br />The Fallen Ones is a bad film, there's no two ways about it as far as I'm concerned. Not recommended on any level or in any way, one to avoid.

Phase diagram of the Hubbard-Holstein model in the coexistence of
electron-electron and electron-phonon interactions has been theoretically
obtained with the density-matrix renormalization group method for
one-dimensional (1D) systems, where an improved warm-up (the recursive sweep)
procedure has enabled us to calculate various correlation functions. We have
examined the cases of (i) the systems half-filled by electrons for the full
parameter space spanned by the electron-electron and electron-phonon coupling
constants and the phonon frequency, (ii) non-half-filled system, and (iii)
trestle lattice. For (i), we have detected a region where both the charge and
on-site pairing correlations decay with power-laws in real space, which
suggests a metallic behavior. While pairing correlations are not dominant in
(i), we have found that they become dominant as the system is doped in (ii), or
as the electronic band structure is modified (with a broken electron-hole
symmetry) in (iii) in certain parameter regions.

Worked at first, but...
These batteries worked great for the price at first, but after a few months of use they started exploding and leaking battery acid. Maybe they got overused since I had to recharge them every night for my purposes; they might be alright if you don’t think you’ll need to use them a whole lot.

Unless the public sector is making a product and selling it; public sector employees are being paid by the money private sector workers pay in taxes from the money they earn from private sector companies that produce and sell a product. All the money starts in the private sector, unless our state government is printing it. Which I'm not aware of.

Does not work.
I could barely get a finger into the jar and had to use so much product. No comparison to the piece/sculpt that you discontinued. Why does Pureology keep discontinuing and replacing with inferior products. Time for me to find another line. This has happened too, too many times.

We investigated the opto-mechanical properties of a Fabry-Perot cavity with a
mirror mounted on a spring. Such a structure allows the cavity length to change
elastically under the effect of light induced forces. This opto-mechanical
coupling is exploited to control the amplitude of mechanical fluctuation of the
mirror. We present a model developed in the classical limit and discuss data
obtained in the particular case for which photo-thermal forces are dominant.
|
We report on the fabrication and characterization of a scannable Fabry-Perot
microcavity, consisting of a curved micromirror at the end of an optical fiber
and a planar distributed Bragg reflector. Furthermore, we demonstrate the
coupling of single organic molecules embedded in a thin film to well-defined
resonator modes. We discuss the choice of cavity parameters that will allow
sufficiently high Purcell factors for enhancing the zero-phonon transition
between the vibrational ground levels of the electronic excited and ground
states.

And to think Harper was raked over the coals by the media and Canadians who always suggested he was selling out Canada to China for even having to face this decision ...... and eventually not allowing the sale.
Now it's a good thing? Unbelievable!

Stellar mass black holes (BHs) are expected to segregate and form a steep
density cusp around supermassive black holes (SMBHs) in galactic nuclei. We
follow the evolution of a multi-mass system of BHs and stars by numerically
integrating the Fokker-Planck energy diffusion equations for a variety of BH
mass distributions. We find that the BHs "self-segregate'', and that the
rarest, most massive BHs dominate the scattering rate closest to the SMBH (<
0.1 pc). BH--BH binaries form out of gravitational wave emission during BH
encounters. We find that the expected rate of BH coalescence events detectable
by Advanced LIGO is ~1 - 100/yr, depending on the initial mass function of
stars in galactic nuclei and the mass of the most massive BHs. We find that the
actual merger rate is likely ~10 times larger than this due to the intrinsic
scatter of stellar densities in many different galaxies. The BH binaries that
form this way in galactic nuclei have significant eccentricities as they enter
the LIGO band (90% with e > 0.9), and are therefore distinguishable from other
binaries, which circularise before becoming detectable. We also show that
eccentric mergers can be detected to larger distances and greater BH masses
than circular mergers, up to ~ 700 solar masses. Future ground-based
gravitational wave observatories will be able to constrain both the mass
function of BHs and stars in galactic nuclei.

"To his credit, Wildrose Leader Brian Jean denounced the bigoted slurs and the people behind them."
Well, not really.
Mr. Jean for all intents and purposes spent the week hiding from the press/media, leaving through back-doors ad cancelling minor appearances. Anyway, the far right lunatic fringe within the Wildrose Party will not be satisfied until the Conservative "movement" in Alberta crashes completely at which point these specimens hope to pick up the pieces and make Alberta into a far-right living hell the United States has become.
One would hope Ms. Notley and the NDP will benefit from the lunatic fringe self-inflicted crash and burn policy. One would hope...........

In this paper, we establish sharp two-sided estimates for the transition
densities of relativistic stable processes [i.e., for the heat kernels of the
operators $m-(m^{2/\alpha}-\Delta)^{\alpha/2}$] in $C^{1,1}$ open sets. Here
$m>0$ and $\alpha\in(0,2)$. The estimates are uniform in $m\in(0,M]$ for each
fixed $M>0$. Letting $m\downarrow0$, we recover the Dirichlet heat kernel
estimates for $\Delta^{\alpha/2}:=-(-\Delta)^{\alpha/2}$ in $C^{1,1}$ open sets
obtained in [14]. Sharp two-sided estimates are also obtained for Green
functions of relativistic stable processes in bounded $C^{1,1}$ open sets.

Nonnegative measure-valued solutions of the continuity equation are uniquely
determined by their initial condition, if the characteristic ODE associated to
the velocity field has a unique solution. In this paper we give a partial
extension of this result to signed measure-valued solutions, under a
quantitative two-sided Osgood condition on the velocity field. Our results
extend those obtained for log-Lipschitz vector fields by Bahouri and Chemin.

Small-amplitude prominence oscillations are usually damped after a few
periods. We study the attenuation of non-adiabatic magnetoacoustic waves in a
slab prominence embedded in the coronal medium. We assume an equilibrium
configuration with a transverse magnetic field to the slab axis and investigate
wave damping by thermal conduction and radiative losses. The differential MHD
equations that govern linear slow and fast modes are numerically solved to
obtain the complex oscillatory frequency and the corresponding eigenfunctions.
We find that coronal thermal conduction and radiative losses from the
prominence plasma reveal as the most relevant damping mechanisms. Both
mechanisms govern together the attenuation of hybrid modes, whereas prominence
radiation is responsible for the damping of internal modes and coronal
conduction essentially dominates the attenuation of external modes. In
addition, the energy transfer between the prominence and the corona caused by
thermal conduction has a noticeable effect on the wave stability, radiative
losses from the prominence plasma being of paramount importance for the thermal
stability of fast modes. We conclude that slow modes are efficiently damped,
with damping times compatible with observations. On the contrary, fast modes
are less attenuated by non-adiabatic effects and their damping times are
several orders of magnitude larger than those observed. The presence of the
corona causes a decrease of the damping times with respect to those of an
isolated prominence slab, but its effect is still insufficient to obtain
damping times of the order of the period in the case of fast modes.

In this note we propose a method to classify homogeneous nilpotent elements
in a real $Z_m$-graded semisimple Lie algebra $g$. Using this we describe the
set of orbits of homogeneous elements in a real $Z_2$-graded semisimple Lie
algebra. A classification of 4-vectors (resp. 4-forms) on $R^8$ can be given
using this method.

Let C be a smooth projective curve with genus g>1 and Clifford index c(C) and
let L be a line bundle on C generated by its global sections. The morphism i:C
-->P(H^0(L))=P is well-defined and i*T is the restriction to C of the tangent
bundle T of the projective space P. Sharpening a theorem by Paranjape, we show
that if deg L>2g-c(C)-1 then i*T is semi-stable, specifying when it is also
stable. We then prove the existence on many curves of a line bundle L of degree
2g-c(C)-1 such that i*T is not semi-stable. Finally, we completely characterize
the (semi-)stability of i*T when C is hyperelliptic.

The bifurcation period in low-mass X-ray binaries is the initial orbital pe-
riod which separates the formation of converging systems (which evolve with
decreasing orbital periods until the donor becomes degenerate) from the
diverging systems (which evolve with increasing orbital periods until the donor
star loses its envelope and a wide detached binary is formed). We calculate
systematically the bifurcation periods of binary systems with a 1.4M_\sun
neutron star and a 0.5-2M_\sun donor star, taking into account different kinds
of magnetic braking and mass loss mechanisms. Our results show that the
saturated magnetic braking can considerably decrease the values of bifurcation
period compared to the traditional magnetic braking, while the influence of
mass loss mechanisms on bifurcation periods is quite weak. We also develop a
semi-analytical method to compute the bifurcation period, the result of which
agrees well with the numerical method in the leading order.

Knowledge graph embedding has recently become a popular way to model
relations and infer missing links. In this paper, we present a group
theoretical perspective of knowledge graph embedding, connecting previous
methods with different group actions. Furthermore, by utilizing Schur's lemma
from group representation theory, we show that the state of the art embedding
method RotatE can model relations from any finite Abelian group.
