Back when Alec Baldwin and Kim Basinger were a mercurial, hot-tempered, high-powered Hollywood couple they filmed this (nearly) scene-for-scene remake of the 1972 Steve McQueen-Ali MacGraw action-thriller about a fugitive twosome. It almost worked the first time because McQueen was such a vital presence on the screen--even stone silent and weary, you could sense his clock ticking, his cagey magnetism. Baldwin is not in Steve McQueen's league, but he has his charms and is probably a more versatile actor--if so, this is not a showcase for his attributes. Basinger does well and certainly looks good, but James Woods is artificially hammy in a silly mob-magnet role. A sub-plot involving another couple taken hostage by Baldwin's ex-partner was unbearable in the '72 film and plays even worse here. As for the action scenes, they're pretty old hat, which causes one to wonder: why even remake the original? ** from ****

Pulsar systems are very good experimental laboratories for the fundamental
physics in extreme environments which cannot be achieved on ground. For
example, the systems are under conditions of high magnetic field strength,
large gravitational potential, and fast rotation, containing highly-ionized hot
plasmas with particle acceleration etc. We can test phenomena related to these
extreme condition in the X-ray to sub-MeV bands. In future, we will get
fantastic capabilities of higher sensitivities, larger effective area, higher
energy resolutions, and X-ray imaging capabilities with wider energy band than
current missions, in addition to opening new eyes of polarization measurements,
and deep all sky monitoring capabilities, with future X-ray missions including
ASTRO-H, eRossita, NuSTAR, GEMS, International X-ray Observatory (IXO) and so
on. In this paper, we summarize current hot topics on pulsars and discuss
expected developments by these future missions, especially by ASTRO-H and IXO,
based on their current design parameters.

She loves it!
My cat is a very peculiar girl. She doesn't take well to new things. I thought she might like this heated cat bed, so I bought it for her. Within 20 minutes she was laying and napping HARD in it. She has yet to move out of it. I think she has a new favorite thing. I am so glad I bought this bed.

Deep learning has achieved remarkable successes in solving challenging
reinforcement learning (RL) problems when dense reward function is provided.
However, in sparse reward environment it still often suffers from the need to
carefully shape reward function to guide policy optimization. This limits the
applicability of RL in the real world since both reinforcement learning and
domain-specific knowledge are required. It is therefore of great practical
importance to develop algorithms which can learn from a binary signal
indicating successful task completion or other unshaped, sparse reward signals.
We propose a novel method called competitive experience replay, which
efficiently supplements a sparse reward by placing learning in the context of
an exploration competition between a pair of agents. Our method complements the
recently proposed hindsight experience replay (HER) by inducing an automatic
exploratory curriculum. We evaluate our approach on the tasks of reaching
various goal locations in an ant maze and manipulating objects with a robotic
arm. Each task provides only binary rewards indicating whether or not the goal
is achieved. Our method asymmetrically augments these sparse rewards for a pair
of agents each learning the same task, creating a competitive game designed to
drive exploration. Extensive experiments demonstrate that this method leads to
faster converge and improved task performance.

This paper reviews the fully complete hypergames model of system $F$,
presented a decade ago in the author's thesis. Instantiating type variables is
modelled by allowing ``games as moves''. The uniformity of a quantified type
variable $\forall X$ is modelled by copycat expansion: $X$ represents an
unknown game, a kind of black box, so all the player can do is copy moves
between a positive occurrence and a negative occurrence of $X$.
This presentation is based on slides for a talk entitled ``Hypergame
semantics: ten years later'' given at `Games for Logic and Programming
Languages', Seattle, August 2006.

Died after 2 months UPDATE -- Quick Replacement Sent
Loved these initially, bright, worked as advertised. But one of the two I bought has already gone out. Have only been using it for 2 months and it's already dead. UPDATE: The company responded immediately when they saw my review and send me a replacement bulb. So great customer service!

I do a lot of squats, lunges, deadlifts...all that good stuff, so I don't really have a problem with my booty, but I thought it would be fun to try this out.It does give it a nice extra lift but the material around my legs is too tight, otherwise it fits good and looks good.

Jebuz Lamont Cranston - it's nice you pay attention to my posts but that's almost stalker territory you're in.
I recall the issue on refugees crossing the border that some posters were frantic with rage that it was happening at all. I simply noted that short of shooting people, greeting, accepting and processing them as we/RCMP were doing was the only option.
Shame you don't like my take on Russia and Ukraine. Crimea River.
And for the umpteenth time; PLEASE stop having my posts deleted because you imagine they mean something they do not.

The data collected in the Shapley-Ames catalog of bright galaxies show that
lenticular (S0) galaxies are typically about a magnitude fainter than both
elliptical (E) and early spiral (Sa) galaxies. Hubble (1936) was therefore
wrong to regard S0 galaxies as being intermediate between morphological types E
and Sa. The observation that E5-E7 galaxies are significantly fainter than
objects of sub-types E0-E5 suggests that many of the flattest 'ellipticals' may
actually be misclassified lenticular galaxies. In particular it is tentatively
suggested all E7 galaxies might actually be misclassified S0_1 (7) galaxies.
The present results are consistent with the view that galaxies belonging to the
S0 class evolved in environments in which they typically lost more than half of
their original luminous material.

We consider the Markovian Master Equation over matrix algebra $\mathbb{M}_d$,
governed by periodic Lindbladian $L_t$ in standard
(Kossakowski-Lindblad-Gorini-Sudarshan) form. It is shown that under
simplifying assumption of commutativity, i.e. if $L_t L_{t'} = L_{t'}L_t$ for
any moments of time $t,t'\in\mathbb{R}_+$, the Floquet normal form of resulting
completely positive dynamical map is not guaranteed to be given by
simultaneously globally Markovian maps. In fact, the periodic part of the
solution is even shown to be necessarily non-Markovian. Two examples in algebra
$\mathbb{M}_2$ are explicitly calculated: a periodically modulated random qubit
dynamics, being a generalization of pure decoherence scheme, and a classically
perturbed two-level system, coupled to reservoir via standard ladder operators.

Are the stellar-mass merging binary black holes, recently detected by their
gravitational wave signal, of stellar or primordial origin? Answering this
question will have profound implications for our understanding of the Universe,
including the nature of dark matter, the early Universe and stellar evolution.
We build on the idea that the clustering properties of merging binary black
holes can provide information about binary formation mechanisms and origin. The
cross-correlation of galaxy with gravitational wave catalogues carries
information about whether black hole mergers trace more closely the
distribution of dark matter -- indicative of primordial origin -- or that of
stars harboured in luminous and massive galaxies -- indicative of a stellar
origin. We forecast the detectability of such signal for several forthcoming
and future gravitational wave interferometers and galaxy surveys, including,
for the first time in such analyses, an accurate modelling for the different
merger rates, lensing magnification and other general relativistic effects. Our
results show that forthcoming experiments could allow us to test most of the
parameter space of the still viable models investigated, and shed more light on
the issue of binary black hole origin and evolution.

For high data rate ultra wideband communication system, performance
comparison of Rake, MMSE and Rake-MMSE receivers is attempted in this paper.
Further a detail study on Rake-MMSE time domain equalizers is carried out
taking into account all the important parameters such as the effect of the
number of Rake fingers and equalizer taps on the error rate performance. This
receiver combats inter-symbol interference by taking advantages of both the
Rake and equalizer structure. The bit error rate performances are investigated
using MATLAB simulation on IEEE 802.15.3a defined UWB channel models.
Simulation results show that the bit error rate probability of Rake-MMSE
receiver is much better than Rake receiver and MMSE equalizer. Study on
non-line of sight indoor channel models illustrates that bit error rate
performance of Rake-MMSE (both LE and DFE) improves for CM3 model with smaller
spread compared to CM4 channel model. It is indicated that for a MMSE equalizer
operating at low to medium SNR values, the number of Rake fingers is the
dominant factor to improve system performance, while at high SNR values the
number of equalizer taps plays a more significant role in reducing the error
rate.

We show that the C*-algebras associated with synchronous games give rise to
certain quantum families of maps between the input and output sets of the game.
In particular situations (e.g. for graph endomorphism games) these quantum
families have a natural quantum semigroup structure and if the condition of
preservation of a natural state is added, they are in fact compact quantum
groups.

We consider the problem of finding an $\varepsilon$-approximate stationary
point of a smooth function on a compact domain of $\mathbb{R}^d$. In contrast
with dimension-free approaches such as gradient descent, we focus here on the
case where $d$ is finite, and potentially small. This viewpoint was explored in
1993 by Vavasis, who proposed an algorithm which, for any fixed finite
dimension $d$, improves upon the $O(1/\varepsilon^2)$ oracle complexity of
gradient descent. For example for $d=2$, Vavasis' approach obtains the
complexity $O(1/\varepsilon)$. Moreover for $d=2$ he also proved a lower bound
of $\Omega(1/\sqrt{\varepsilon})$ for deterministic algorithms (we extend this
result to randomized algorithms).
Our main contribution is an algorithm, which we call gradient flow trapping
(GFT), and the analysis of its oracle complexity. In dimension $d=2$, GFT
closes the gap with Vavasis' lower bound (up to a logarithmic factor), as we
show that it has complexity
$O\left(\sqrt{\frac{\log(1/\varepsilon)}{\varepsilon}}\right)$. In dimension
$d=3$, we show a complexity of
$O\left(\frac{\log(1/\varepsilon)}{\varepsilon}\right)$, improving upon
Vavasis' $O\left(1 / \varepsilon^{1.2} \right)$. In higher dimensions, GFT has
the remarkable property of being a logarithmic parallel depth strategy, in
stark contrast with the polynomial depth of gradient descent or Vavasis'
algorithm. In this higher dimensional regime, the total work of GFT improves
quadratically upon the only other known polylogarithmic depth strategy for this
problem, namely naive grid search. We augment this result with another
algorithm, named \emph{cut and flow} (CF), which improves upon Vavasis'
algorithm in any fixed dimension.

The character of the superconducting phase of Sr$_2$RuO$_4$, is topic of a
longstanding discussion. The classification of the symmetry allowed order
parameters has relied on the tetragonal symmetry of the lattice and on
cylindrical Fermi surfaces, usually taken to be featureless, not including the
non-trivial symmetry aspects related to their orbital content. Here we show how
the careful account of the orbital degree of freedom in Sr$_2$RuO$_4$, leads to
a much richer classification of order parameters. We analyse the stability and
degeneracy of these new order parameters from the perspective of the concept of
superconducting fitness and propose a new best order parameter candidate.

An electrohydrodynamic (EHD) flow in a point-to-ring corona configuration is
investigated experimentally, analytically and via a multiphysics numerical
model. The interaction between the accelerated ions and the neutral gas
molecules is modeled as an external body force in the Navier-Stokes equation
(NSE). The gas flow characteristics are solved from conservation principles
with spectral methods. The analytical and numerical simulation results are
compared against experimental measurements of the cathode voltage, ion
concentration, and velocity profiles. A nondimensional parameter, X, is
formulated as the ratio of the local electric force to the inertial term in the
NSE. In the region of X > 1, the electric force dominates the flow dynamics,
while in the X << 1 region, the balance of viscous and inertial terms yields
traditional pipe flow characteristics.

I normally don't comment on movies on IMDB, but in this case I feel like I should. I love movies, and I want to make them, and this movie is a perfect example of fine filmmaking.<br /><br />This is one of the few movies that I have seen on the small screen (originally seeing it air on AMC, I believe, and then on the DVD I just watched) that made me get that feeling in the pit of my stomach. That little gnawing sensation that the director would hope you feel while watching his thriller.<br /><br />Jack Lemmon's performance is a fine one, and Jane Fonda and Michael Douglas follow. I felt so much empathy of Lemmon, who's character Jack Godell, only wanted people to listen to his warning.<br /><br />But what impresses me most about this film is the lack of a score, and this is also what makes it beautiful to me. Apart from the opening titles there are no background music to increase the tension, because none is needed. And while the credits run, white on black, in silence it drives the point home.<br /><br />I use the movie as an example to anyone who says music makes the movie. I think the movie should make the movie and the music should only amplify that. But for The China Syndrome music is not necessary to get across the realism and the urgency depicted here. The characters portray all of this far better than the music ever could.<br /><br />I highly recommend this movie, it is one of my favorites. If you like movies, you won't be disappointed. If you like movie soundtracks more, you might not want to give this one a go.

Modifications of General Relativity leave their imprint both on the cosmic
expansion history through a non-trivial dark energy equation of state, and on
the evolution of cosmological perturbations in the scalar and in the tensor
sectors. In particular, the modification in the tensor sector gives rise to a
notion of gravitational-wave (GW) luminosity distance, different from the
standard electromagnetic luminosity distance, that can be studied with standard
sirens at GW detectors such as LISA or third-generation ground based
experiments. We discuss the predictions for modified GW propagation from some
of the best studied theories of modified gravity, such as Horndeski or the more
general degenerate higher order scalar-tensor (DHOST) theories, non-local
infrared modifications of gravity, bigravity theories and the corresponding
phenomenon of GW oscillation, as well as theories with extra or varying
dimensions. We show that modified GW propagation is a completely generic
phenomenon in modified gravity. We then use a simple parametrization of the
effect in terms of two parameters $(\Xi_0,n)$, that is shown to fit well the
results from a large class of models, to study the prospects of observing
modified GW propagation using supermassive black hole binaries as standard
sirens with LISA. We construct mock source catalogs and perform detailed Markov
Chain Monte Carlo studies of the likelihood obtained from LISA standard sirens
alone, as well as by combining them with CMB, BAO and SNe data to reduce the
degeneracies between cosmological parameters. We find that the combination of
LISA with the other cosmological datasets allows one to measure the parameter
$\Xi_0$ that characterizes modified GW propagation to the percent level
accuracy, sufficient to test several modified gravity theories. [Abridged]

A potential explanation for the spatiotemporal accumulation of pathological lesions in the brain of patients with neurodegenerative protein misfolding diseases (PMDs) is cell-to-cell transmission of aggregation-prone, misfolded proteins. Little is known about central to peripheral transmission and its contribution to pathology. We show that transmission of Huntingtons disease- (HD-) associated mutant HTT exon 1 (mHTTEx1) occurs across the neuromuscular junctions in human iPSC cultures and in vivo in wild-type mice. We found that transmission is an active and dynamic process, that happens prior to aggregate formation and is regulated by synaptic activity. Furthermore, we find that transmitted mHTTEx1 causes HD-relevant pathology at a molecular and functional level in human muscle cells, even in the presence of ubiquitous expression mHTTEx1. With this work we uncover a casual-link between mHTTEx1 synaptic transmission and pathology, highlighting the therapeutic potential in blocking toxic protein transmission in PMDs.

The atmospheric structure of chemically peculiar stars deviates from that of
normal stars with similar fundamental parameters due to unusual chemistry,
abundance inhomogeneities and the presence of strong magnetic field. These
effects are not considered in the standard model atmospheres, possibly leading
to large errors in the stellar parameter determination and abundance analysis.
To tackle this problem we used the state-of-the-art opacity sampling model
atmosphere code LLmodels to calculate comprehensive grid of new generation
model atmospheres for magnetic CP stars. This grid covers the whole parameter
space occupied by SrCrEu and Si-peculiar stars, taking into account
characteristic temperature dependence of the chemical abundances. Here we
present the first results of our model atmosphere calculations.

A Vehicular Ad-Hoc Network (VANET) is a form of Mobile ad-hoc network, to
provide communications among nearby vehicles and between vehicles and nearby
fixed roadside equipment. The key operation in VANETs is the broadcast of
messages. Consequently, the vehicles need to make sure that the information has
been sent by an authentic node in the network. VANETs present unique challenges
such as high node mobility, real-time constraints, scalability, gradual
deployment and privacy. No existent technique addresses all these requirements.
In particular, both inter-vehicle and vehicle-to-roadside wireless
communications present different characteristics that should be taken into
account when defining node authentication services. That is exactly what is
done in this paper, where the features of inter-vehicle and vehicle-to-roadside
communications are analyzed to propose differentiated services for node
authentication, according to privacy and efficiency needs.

Extremely thin
I've been looking at this shower curtain for over a year and finally bit the bullet and paid the $50 for it. I am so disappointed! As many have said, it's very thin. There is no texture to it at all, but it does look just like the picture. It's very pretty, but when looking closely at it, it's just a pattern printed on a sheet of thin cotton. I am really wanting to return it and pay $20 for a much thicker on at Wal Mart, but I am just so sad!!

Distributing entangled photon pairs over noisy channels is an important task
for various quantum information protocols. Encoding an entangled state in a
decoherence-free subspace (DFS) formed by multiple photons is a promising way
to circumvent the phase fluctuations and polarization rotations in optical
fibres. Recently, it has been shown that the use of a counter-propagating
coherent light as an ancillary photon enables us to faithfully distribute
entangled photon with success probability proportional to the transmittance of
the optical fibres. Several proof-of-principle experiments have been
demonstrated, in which entangled photon pairs from a sender side and the
ancillary photon from a receiver side originate from the same laser source. In
addition, bulk optics have been used to mimic the noises in optical fibres.
Here, we demonstrate a DFS-based entanglement distribution over 1km-optical
fibre using DFS formed by using fully independent light sources at the telecom
band. In the experiment, we utilize an interference between asynchronous
photons from cw-pumped spontaneous parametric down conversion (SPDC) and
mode-locked coherent light pulse. After performing spectral and temporal
filtering, the SPDC photons and light pulse are spectrally indistinguishable.
This property allows us to observe high-visibility interference without
performing active synchronization between fully independent sources.

Nice watch but no support as not all notifications work
Though I like the watch - it’s notification capabilities are not working in their entirety. Just sms. And not email or Instagram alerts which are on their app, but don’t work. The app says twitter, Facebook and other Chinese social media notifications but I don’t need all that. Tried emailing support but no response. Website is in Chinese. There is no phone number either. If they fix this I will happily edit my ratings but if not, this will be returned. Hope they read these reviews although that might be wishful thinking.

We introduce and study a class of models of free fermions hopping between
neighbouring sites with random Brownian amplitudes. These simple models
describe stochastic, diffusive, quantum, unitary dynamics. We focus on periodic
boundary conditions and derive the complete stationary distribution of the
system. It is proven that the generating function of the latter is provided by
the Harish-Chandra-Itzykson-Zuber integral which allows us to access all
fluctuations of the system state. The steady state is characterized by non
trivial correlations which have a topological nature. Diagrammatic tools
appropriate for the study of these correlations are presented. In the
thermodynamic large system size limit, the system approaches a non random
equilibrium state plus occupancy and coherence fluctuations of magnitude
scaling proportionally with the inverse of the square root of the volume. The
large deviation function for those fluctuations is determined. Although
decoherence is effective on the mean steady state, we observe that sub-leading
fluctuating coherences are dynamically produced from the inhomogeneities of the
initial occupancy profile.

First off, this is the worst movie I've ever seen. That may make you want to see it, but it is not bad in a good way. It's boring, implausible, poorly shot, ridiculously scripted, and lacking in cool disaster effects.<br /><br />Worse, it is intensely patriotic without a trace of irony or fun, wallowing in a sense of Japanese uniqueness and victimhood. Everyone abandons the Japanese in their hour of need. Particularly the Koreans. The most noble characters choose seppaku -- going down with their ship as their beloved island sinks. "Only Japanese would think this way," says the prime minister.<br /><br />If this movie in any way reflects the Japanese opinion of their place in world opinion, the first thing they should do to rectify the problem is stop making movies like this.

DP-coloring (also called correspondence coloring) is a generalization of list
coloring introduced by Dvo\v{r}\'{a}k and Postle in 2015. In 2019, Bernshteyn,
Kostochka, and Zhu introduced a fractional version of DP-coloring. They showed
that unlike the fractional list chromatic number, the fractional DP-chromatic
number of a graph $G$, denoted $\chi_{DP}^*(G)$, can be arbitrarily larger than
$\chi^*(G)$, the graph's fractional chromatic number. In this note we show that
for any $n \geq 2$ and $m \in \mathbb{N}$, there is a $t \in \mathbb{N}$ such
that $\chi_{DP}^*(K_{n,m}) \leq n + 1 - 1/t$, and we determine a lower bound on
$\chi_{DP}^*(K_{2,m})$ for any $m \geq 3$. We also generalize a result of Alon,
Tuza, and Voigt, and in the process, show that for each $k \in \mathbb{N}$,
$\chi_{DP}^*(C_{2k+1}) = \chi^*(C_{2k+1})$.

The Tayler instability (TI) is a non-axisymmetric linear instability of an
axisymmetric toroidal magnetic field in magneto-hydrostatic equilibrium (MHSE).
Spruit (1999, 2002) has proposed that in a differentially rotating radiative
region of a star, the TI drives a dynamo which generates magnetic fields that
can efficiently transport angular momentum; a parameterized version of this
dynamo has been implemented in stellar structure and evolution codes and shown
to be important for determining interior spin. Numerical simulations, however,
have yet to definitively demonstrate the operation of the dynamo. A criterion
for the MHSE to develop the TI was derived using fully-compressible
magneto-hydrodynamics, while numerical simulations of dynamical processes in
stars frequently use an anelastic approximation. This motivates us to derive a
new anelastic Tayler instability (anTI) criterion. We find that some MHSE
configurations unstable in the fully-compressible case, become stable in the
anelastic case. We find and characterize the unstable modes of a simple family
of cylindrical MHSE configurations using numerical calculations, and discuss
the implications for fully non-linear anelastic simulations.

Housing affordability: Two New Year’s resolutions for state
Image 1 of / 1 Caption Close Housing affordability: Two New Year’s resolutions for state 1 / 1 Back to Gallery
The lack of affordable housing in many Connecticut communities is more than a zoning or diversity issue, it is a human rights issue. A decent place to live in any of our 169 towns should not be a privilege of the wealthy — it should be a basic right of all residents of our state.
In many of our communities, teachers, law enforcement personnel and first responders cannot afford to live where they work and many young people cannot afford to stay where they grew up. Ensuring that the elderly can continue to live in the communities where they have lived their lives and that young people can stay in the towns where they were raised helps create the diversity that makes a town a true community.
Exclusionary zoning laws and the lack of affordable housing in some Connecticut towns conspire to keep many people out. We have serious problems, but they can be solved — if the General Assembly has the will to do so. Since we cannot create more land, the only solution is to make the best use of the finite land within our borders.
The authority to regulate the use of land is fundamentally a state power, the so-called “police power” to protect and promote the public’s health, safety, and general welfare. It arises from the Tenth Amendment to the Constitution, which gives states the rights and powers “not delegated to the United States.”
Some lawmakers forget or ignore that the state is the sole source of the power to regulate land, partially because the state has granted local governments broad powers through charters and enabling legislation. In the name of home rule, some lawmakers deny that the General Assembly has the primary responsibility as to land use. Casting housing affordability as a “local issue” has enabled them to kick the can down the road for decades.
In 2020, the General Assembly should resolve to exercise its exclusive authority to address two of Connecticut’s top land use issues:
1. Affordable Housing
The National Low-Income Housing Coalition ranks Connecticut 9th in the country in terms of wages required to afford a two-bedroom rental home without the household paying more than 30 percent of its income. Forty-one states are more affordable than Connecticut. That is shameful. Our state also has a half million renter households, many who need housing assistance.
The Affordable Housing Land Use Appeals law enacted 30 years ago allowed an override of local zoning for producing affordable housing but has so far produced just 5,000 units, a drop in the bucket. The appeals process can take over a decade and costs a small fortune. The law could be strengthened and should be kept, but we need additional solutions and we need them fast.
The General Assembly should do what Vermont, California, and Oregon have done at the state level and what Minneapolis and Seattle have done locally and mandate that anyone with a single-family home can add one or two additional units on their lot.
There are 1.4 million housing units in Connecticut and more than 800,000 are single-family detached homes. If the General Assembly would follow the lead of Vermont and the other states, Connecticut’s 800,000 homeowners could produce over 100,000 new units, mostly affordable, without a dime of government money, no court appeals and no big lawyer bills.
The land, utilities, and site improvements are free because they are already there. If a mere 5 percent of those single-family homeowners created just one new unit inside their home or over their garage or with an addition or freestanding cottage, we would have 40,000 new housing units.
If another 5 percent were to decide to do two units on their large suburban and rural lots, we would have a total of 120,000 new homes and it would happen almost overnight and be better suited to the smaller households of today. The immediate increase in housing units would soften the housing market across the board, increasing affordability.
If Vermont, California, and Oregon can do it, why can’t Connecticut?
2. State Land Use Regulations
The statues granting local governments the power to regulate land use are a mess, a hodgepodge of piecemeal legislation, often designed to promote narrow interests. Some statutory provisions have made Connecticut the laughingstock of the rest of the country including one law in the Connecticut General Statutes that protects a single landowner.
There is little integration of zoning and wetlands regulation, the procedural time limits are arcane, the process is exceedingly slow and requires heavy-duty lawyering at almost every turn. None of the stakeholders — developers, local governments, neighbors, advocacy groups — are well-served.
In 2020, lawmakers should resolve to create a Blue-Ribbon Commission, bring in experts from around the country to help us completely redo the statutes so Connecticut can emerge from the Stone Age. Fifteen years ago, the American Planning Association developed model state enabling legislation called the Growing Smart program and issued a report of over 1,000 pages for all to use for free. A decade and half later, we are still stuck with our utterly dysfunctional enabling statute. The solutions exist and Connecticut should take advantage of them.

We propose Generative Well-intentioned Networks (GWINs), a novel framework
for increasing the accuracy of certainty-based, closed-world classifiers. A
conditional generative network recovers the distribution of observations that
the classifier labels correctly with high certainty. We introduce a reject
option to the classifier during inference, allowing the classifier to reject an
observation instance rather than predict an uncertain label. These rejected
observations are translated by the generative network to high-certainty
representations, which are then relabeled by the classifier. This architecture
allows for any certainty-based classifier or rejection function and is not
limited to multilayer perceptrons. The capability of this framework is assessed
using benchmark classification datasets and shows that GWINs significantly
improve the accuracy of uncertain observations.

A review is presented of the development and current status of nuclear
shell-model calculations in which the two-body effective interaction is derived
from the free nucleon-nucleon potential. The significant progress made in this
field within the last decade is emphasized, in particular as regards the
so-called V-low-k approach to the renormalization of the bare nucleon-nucleon
interaction. In the last part of the review we first give a survey of realistic
shell-model calculations from early to present days. Then, we report recent
results for neutron-rich nuclei near doubly magic 132Sn and for the whole
even-mass N=82 isotonic chain. These illustrate how shell-model effective
interactions derived from modern nucleon-nucleon potentials are able to provide
an accurate description of nuclear structure properties.

In other words: Tsk, there is much friction between me and those who disagree with my political beliefs. The obvious solution is for these people to accept that I'm right, and they're wrong.
Keep on trying, but we just had an election and your side lost. Preaching to the defeated choir isn't helping anyone.

Permutation invariant Gaussian matrix models were recently developed for
applications in computational linguistics. A 5-parameter family of models was
solved. In this paper, we use a representation theoretic approach to solve the
general 13-parameter Gaussian model, which can be viewed as a zero-dimensional
quantum field theory. We express the two linear and eleven quadratic terms in
the action in terms of representation theoretic parameters. These parameters
are coefficients of simple quadratic expressions in terms of appropriate linear
combinations of the matrix variables transforming in specific irreducible
representations of the symmetric group $S_D$ where $D$ is the size of the
matrices. They allow the identification of constraints which ensure a
convergent Gaussian measure and well-defined expectation values for polynomial
functions of the random matrix at all orders. A graph-theoretic interpretation
is known to allow the enumeration of permutation invariants of matrices at
linear, quadratic and higher orders. We express the expectation values of all
the quadratic graph-basis invariants and a selection of cubic and quartic
invariants in terms of the representation theoretic parameters of the model.

The properties of pairing correlations in symmetric nuclear matter are
studied in the relativistic mean field (RMF) theory with the effective
interaction PK1. Considering well-known problem that the pairing gap at Fermi
surface calculated with RMF effective interactions are three times larger than
that with Gogny force, an effective factor in the particle-particle channel is
introduced. For the RMF calculation with PK1, an effective factor 0.76 give a
maximum pairing gap 3.2 MeV at Fermi momentum 0.9 fm$^{-1}$, which are
consistent with the result with Gogny force.

i prefer the TAT be used for rail because it forces the County to be more accountable for the Rail instead of asking for State handouts every time HART and Caldwell misdraft a budget or contract (every time). It's a naive hope that if the County is being forced to utilize a tax that relates to County spending like the TAT they'll be more careful about the rail.
I believe that some of those issues you mentioned, particularly homeless and environmental issues related to global warming have been addressed with bills that passed this session (not as much as I'd hope but they did soldier through).
Though, in relation to Airbnb, they were really adamant on not releasing names of their landlords. I saw a few clips of the hearing on Olelo and in the news but they cited legal issues and a Higher court ruling that said it was illegal to release the names. But, it's very relieving to hear about the SF registration system and hopefully it'll mean Hawaii will soon follow suit.

Deeply inside dense molecular clouds and protostellar disks, the interstellar
ices are protected from stellar energetic UV photons. However, X-rays and
energetic cosmic rays can penetrate inside these regions triggering chemical
reactions, molecular dissociation and evaporation processes. We present
experimental studies on the interaction of heavy, highly charged and energetic
ions (46 MeV Ni^13+) with ammonia-containing ices in an attempt to simulate the
physical chemistry induced by heavy ion cosmic rays inside dense astrophysical
environments. The measurements were performed inside a high vacuum chamber
coupled to the heavy ion accelerator GANIL (Grand Accelerateur National d'Ions
Lourds) in Caen, France.\textit{In-situ} analysis is performed by a Fourier
transform infrared spectrometer (FTIR) at different fluences. The averaged
values for the dissociation cross section of water, ammonia and carbon monoxide
due to heavy cosmic ray ion analogs are ~2x10^{-13}, 1.4x10^{-13} and
1.9x10^{-13} cm$^2$, respectively. In the presence of a typical heavy cosmic
ray field, the estimated half life for the studied species is 2-3x10^6 years.
The ice compaction (micropore collapse) due to heavy cosmic rays seems to be at
least 3 orders of magnitude higher than the one promoted by (0.8 MeV) protons .
In the case of the irradiated H2O:NH3:CO ice, the infrared spectrum at room
temperature reveals five bands that were tentatively assigned to vibration
modes of the zwitterionic glycine (+NH3CH2COO-).

We report the inverse Laplace transform (ILT) analysis of the $^{139}$La
nuclear spin-lattice relaxation rate $1/T_1$ in charge ordered
La$_{1.885}$Sr$_{0.115}$CuO$_4$ ($T_{charge} \sim 80$K, $T_{c} \simeq
T_{spin}^{neutron}=30$K), and shed new light on its magnetic inhomogeneity. We
deduce the probability density function $P(1/T_{1})$ of the distributed $1/T_1$
(i.e. the histogram of distributed $1/T_1$) by taking the inverse Laplace
transform of the experimentally observed nuclear magnetization recovery curve
$M(t)$. We demonstrate that spin freezing sets in in some domains precisely
below the onset of charge order at $T_{charge}$, but their volume fraction
grows only gradually toward $T_{c}$. Nearly a half of the sample volume
exhibits properties expected for canonical high $T_c$ cuprates without charge
order even near $T_c$. Our findings explain why charge order does not suppress
$T_c$ of La$_{1.885}$Sr$_{0.115}$CuO$_4$ as significantly as in
La$_{1.875}$Ba$_{0.125}$CuO$_4$.

Rep. Adam B. Schiff (Calif.), the ranking Democrat on the House Intelligence Committee, called Mueller’s impaneling of a D.C. grand jury “a significant development,” noting that it has been more than a year since former FBI director James B. Comey launched a counterintelligence investigation into Russia’s meddling in the 2016 election.
“That means one year later, rather than turning that investigation off, rather than concluding ‘We’ve looked at this for a year; there’s really nothing to see here,’ as the president would claim, instead . . . it’s moving into a new phase,” Schiff said during an appearance on CNN’s “State of the Union.” “That wouldn’t be taking place if there was really no evidence, no evidentiary basis to move forward.”…

One would think that since this issue has vexed the church for the better part of two millennia they would have come to better resolution, n'est pas?
What does it take our hierarchs to understand that the teaching is based on chiefly misunderstanding of human sexuality and the political hegemony of patriarchy?
If the church repeatedly clings to a teaching that is demonstrably against the very nature of even the men who constitute the priesthood [both historically and currently], that someone along the line would have gotten the idea that maybe this teaching is a form of idolatry? Dontcha' think?
Why would a hierarchy of a church that follows the teachings of the Beatitudes continually ask men to lie everyday about the fundamental truth of their being, their person?

We study the perturbations of a relatively close third star on a tidally
distorted eccentric eclipsing binary. We consider both the observational
consequences of the variations of the orbital elements and the interactions of
the stellar rotation with the orbital revolution in the presence of
dissipation. We concentrate mainly on the effect of a hypothetical third
companion on both the real, and the observed apsidal motion period. We
investigate how the observed period derived mainly from some variants of the
O-C relates to the real apsidal motion period. We carried out both analytical
and numerical investigations and give the time variations of the orbital
elements of the binary both in the dynamical and the observational reference
frames. We give the direct analytical form of an eclipsing O-C affected
simultaneously by the mutual tidal forces and the gravitational interactions
with a tertiary. We also integrated numerically simultaneously the orbital and
rotational equations for the possible hierarchical triple stellar system AS
Camelopardalis. We find that there is a significant domain of the possible
hierarchical triple system configurations, where both the dynamical and the
observational effects tend to measure longer apsidal advance rate than is
expected theoretically. This happens when the mutual inclination of the close
and the wide orbits is large, and the orbital plane of the tertiary almost
coincides with the plane of the sky. We also obtain new numerical results on
the interaction of the orbital evolution and stellar rotation in such triplets.
The most important fact is that resonances might occur as the stellar
rotational rate varies during the dissipation-driven synchronization process...

Simultaneous $\chi^{2}$ analyses previously made for elastic scattering and
fusion cross section data for the $^{6}$Li+$^{208}$Pb system is extended to the
$^{7}$Li+$^{208}$Pb system at near-Coulomb-barrier energies based on the
extended optical model approach, in which the polarization potential is
decomposed into direct reaction (DR) and fusion parts. Use is made of the
double folding potential as a bare potential. It is found that the experimental
elastic scattering and fusion data are well reproduced without introducing any
normalization factor for the double folding potential and that both the DR and
fusion parts of the polarization potential determined from the $\chi^{2}$
analyses satisfy separately the dispersion relation. Further, we find that the
real part of the fusion portion of the polarization potential is attractive
while that of the DR part is repulsive except at energies far below the Coulomb
barrier energy. A comparison is made of the present results with those obtained
from the Continuum Discretized Coupled Channel (CDCC) calculations and a
previous study based on the conventional optical model with a double folding
potential. We also compare the present results for the $^7$Li+$^{208}$Pb system
with the analysis previously made for the $^{6}$Li+$^{208}$Pb system.

cat does not like it
I bought this product for my cat. Unfortunately he does not like the taste so I have a bit more trouble getting him to take this than I did with the Salmon flavor which he loved. Since he is a cat, smell and flavor are important is getting a good response. It has a very strong smell that kind of sticks around after you use it. The product works, just not the flavor. Might be better for a dog..

While many viruses have a single natural host, host restriction can be incomplete, hereby leading to spillovers to other host species. However, such spillover risks are difficult to quantify. As climate change is rapidly transforming environments, it is becoming critical to quantify the potential for spillovers. To address this issue, we resorted to an unbiased metagenomics approach, and focused on two environments, soil and lake sediments from Lake Hazen, the largest High Arctic freshwater lake in the world. We used DNA and RNA sequencing to reconstruct the lakes virosphere and its range of eukaryotic hosts, and estimated the spillover risk by measuring the congruence between the viral and the eukaryotic host phylogenetic trees. We show that spillover risk is higher in lake sediments than in soil and increased with runoff from glacier melt, a proxy for climate change. Should climate change also shift species range of potential viral vectors and reservoirs northwards, the High Arctic could become fertile ground for emerging pandemics.

Vision, as an inexpensive yet information rich sensor, is commonly used for
perception on autonomous mobile robots. Unfortunately, accurate vision-based
perception requires a number of assumptions about the environment to hold --
some examples of such assumptions, depending on the perception algorithm at
hand, include purely lambertian surfaces, texture-rich scenes, absence of
aliasing features, and refractive surfaces. In this paper, we present an
approach for introspective vision for obstacle avoidance (IVOA) -- by
leveraging a supervisory sensor that is occasionally available, we detect
failures of stereo vision-based perception from divergence in plans generated
by vision and the supervisory sensor. By projecting the 3D coordinates where
the plans agree and disagree onto the images used for vision-based perception,
IVOA generates a training set of reliable and unreliable image patches for
perception. We then use this training dataset to learn a model of which image
patches are likely to cause failures of the vision-based perception algorithm.
Using this model, IVOA is then able to predict whether the relevant image
patches in the observed images are likely to cause failures due to vision (both
false positives and false negatives). We empirically demonstrate with extensive
real-world data from both indoor and outdoor environments, the ability of IVOA
to accurately predict the failures of two distinct vision algorithms.

Many complex discourse-level tasks can aid domain experts in their work but
require costly expert annotations for data creation. To speed up and ease
annotations, we investigate the viability of automatically generated annotation
suggestions for such tasks. As an example, we choose a task that is
particularly hard for both humans and machines: the segmentation and
classification of epistemic activities in diagnostic reasoning texts. We create
and publish a new dataset covering two domains and carefully analyse the
suggested annotations. We find that suggestions have positive effects on
annotation speed and performance, while not introducing noteworthy biases.
Envisioning suggestion models that improve with newly annotated texts, we
contrast methods for continuous model adjustment and suggest the most effective
setup for suggestions in future expert tasks.

We are constructing a program to estimate the redshifts for GRBs from the
original Swift light curves and spectra, aiming to get redshifts for the Swift
bursts \textit{without} spectroscopic or photometric redshifts. We derive the
luminosity indicators from the light curves and spectra of each burst,
including the lag time between low and high photon energy light curves, the
variability of the light curve, the peak energy of the spectrum, the number of
peaks in the light curve, and the minimum rise time of the peaks. These
luminosity indicators can each be related directly to the luminosity, and we
combine their independent luminosities into one weighted average. Then with our
combined luminosity value, the observed burst peak brightness, and the
concordance redshift-distance relation, we can derive the redshift for each
burst. In this paper, we test the accuracy of our method on 107 bursts with
known spectroscopic redshift. The reduced $\chi^2$ of our best redshifts
($z_{best}$) compared with known spectroscopic redshifts ($z_{spec}$) is 0.86,
and the average value of $log_{10}(z_{best}/z_{spec})$ is 0.01, with this
indicating that our error bars are good and our estimates are not biased. The
RMS scatter of $log_{10}(z_{best}/z_{spec})$ is 0.26. For Swift bursts measured
over a relatively narrow energy band, the uncertainty in determining the peak
energy is one of the main restrictions on our accuracy. Although the accuracy
of our $z_{best}$ values are not as good as that of spectroscopic redshifts, it
is very useful for demographic studies, as our sample is nearly complete and
the redshifts do not have the severe selection effects associated with optical
spectroscopy.

We argue that the spectral theory of non-reversible Markov chains may often
be more effectively cast within the framework of the naturally associated
weighted-$L_\infty$ space $L_\infty^V$, instead of the usual Hilbert space
$L_2=L_2(\pi)$, where $\pi$ is the invariant measure of the chain. This
observation is, in part, based on the following results. A discrete-time Markov
chain with values in a general state space is geometrically ergodic if and only
if its transition kernel admits a spectral gap in $L_\infty^V$. If the chain is
reversible, the same equivalence holds with $L_2$ in place of $L_\infty^V$, but
in the absence of reversibility it fails: There are (necessarily
non-reversible, geometrically ergodic) chains that admit a spectral gap in
$L_\infty^V$ but not in $L_2$. Moreover, if a chain admits a spectral gap in
$L_2$, then for any $h\in L_2$ there exists a Lyapunov function $V_h\in L_1$
such that $V_h$ dominates $h$ and the chain admits a spectral gap in
$L_\infty^{V_h}$. The relationship between the size of the spectral gap in
$L_\infty^V$ or $L_2$, and the rate at which the chain converges to equilibrium
is also briefly discussed.

Using a combined quantum mechanical/classical method, we study the collisions
of small Na clusters on large Ar clusters as a model for cluster deposit. We
work out basic mechanisms by systematic variation of collision energy, system
sizes, and orientations. The soft Ar material is found to serve as an extremely
efficient shock absorber. The collisional energy is quickly transfered at first
impact and the Na clusters are always captured by the Ar surface. The
distribution of the collision energy into the Ar system proceeds very fast with
velocity of sound. The relaxation of shapes goes at a slower pace using times
of several ps. It produces a substantial rearrangement of the Ar system while
the Na cluster remains rather robust.

The increasing number of transiting planets raises the possibility of finding
changes in their transit time, duration and depth that could be indicative of
further planets in the system. Experience from eclipsing binaries indeed shows
that such changes may be expected. A first obvious candidate to look for a
perturbing planet is GJ 436, which hosts a hot transiting Neptune-mass planet
in an eccentric orbit. Ribas et al. (2008) suggested that such eccentricity and
a possible change in the orbital inclination might be due to a perturbing small
planet in a close-in orbit. A radial velocity signal of a 5 M_earth planet
close to the 2:1 mean-motion resonance seemed to provide the perfect candidate.
Recent new radial velocities have deemed such signal spurious. Here we put all
the available information in context and we evaluate the possibility of a small
perturber to GJ 436 b to explain its eccentricity and possible inclination
change. In particular, we discuss the constraints provided by the transit time
variation data. We conclude that, given the current data, the close-in
perturber scenario still offers a plausible explanation to the observed orbital
and physical properties of GJ 436 b.

There's so many negative reviews about "Stay away, Joe" in here I just can't stay quiet any longer and let this injustice happen. Here's a side you haven't heard yet.<br /><br />Elvis Presley's movies are my guilty pleasure for a simple reason: they are perfect films for a pure relaxation because I don't have to think when I watch them. That means I don't have to worry about missing a complex plot because there never is a proper plot to start with. I can just kick off my shoes, grab a beer, sit back, switch off my brains and enjoy all the general wackiness and catchy easy-going rock n' roll tunes from the grooviest decade of them all.<br /><br />In my books "Stay away, Joe" definitely falls into the "so bad it's good"-category. Now if you're like me and appreciate "the trash value", this is the ultimate 1960's camp experience. It's so bad that it's almost surrealistic to watch and just when you think that it can't possibly get any worse it surprises you in the most imaginable ways. In the end you're so amazed by all the new levels of stupidity you just don't know whether to laugh or cry. In a nutshell: I love it because it's so damn amusing that there once was a generation that actually made films like this. I still give it 1 out of 10 though - once it hits the bottom 100 it will became an instant bad movie classic.

We introduce a new scheme for generating short-wavelength coherent broadband
radiation with well-controlled spectral characteristics. It is based on shaping
long-wavelength femtosecond pulse to coherently control atomic
resonance-mediated (2+1) three-photon excitation to a broad far-from-resonance
continuum. Here, the spectrum (central frequency and bandwidth) of
deep-ultraviolet coherent broadband radiation generated in Na vapor is
experimentally controlled by tuning the linear chirp we apply to the driving
phase-shaped near-infrared femtosecond pulse. This is a first step in
implementing the full scheme for producing shaped femtosecond pulses at
wavelengths down-to the vacuum-ultraviolet range.

In recent years argument has been made that a high fraction of early-type
galaxies in the local universe experience low levels (< 1 M_sun/yr) of star
formation (SF) that causes strong excess in UV flux, yet leaves the optical
colors red. Many of these studies were based on GALEX imaging of SDSS galaxies
(z~0.1), and were thus limited by its 5" FWHM. Poor UV resolution left other
possibilities for UV excess open, such as the old populations or an AGN. Here
we study high-resolution far-ultraviolet HST/ACS images of optically quiescent
early-type galaxies with strong UV excess. The new images show that
three-quarters of these moderately massive (~5x10^10 M_sun) early-type galaxies
shows clear evidence of extended SF, usually in form of wide or concentric UV
rings, and in some cases, striking spiral arms. SDSS spectra probably miss
these features due to small fiber size. UV-excess early-type galaxies have on
average less dust and larger UV sizes (D>40 kpc) than other green-valley
galaxies, which argues for an external origin for the gas that is driving the
SF. Thus, most of these galaxies appear `rejuvenated' (e.g., through minor
gas-rich mergers or IGM accretion). For a smaller subset of the sample, the
declining SF (from the original internal gas) cannot be ruled out. SF is rare
in very massive early-types (M_* > 10^11 M_sun), a possible consequence of AGN
feedback. In addition to extended UV emission, many galaxies show a compact
central source, which may be a weak, optically inconspicuous AGN.

We consider a time-slotted two-hop wireless system in which the sources
transmit to the relays in the even time slots (first hop) and the relays
forward the packets to the destinations in the odd time slots (second hop).
Each source may connect to multiple relays in the first hop. In the presence of
interference and without tight coordination of the relays, it is not clear
which relays should transmit the packet. We propose four decentralized methods
of relay selection, some based on location information and others based on the
received signal strength (RSS). We provide a complete analytical
characterization of these methods using tools from stochastic geometry. We use
simulation results to compare these methods in terms of end-to-end success
probability.

We analyze and completely describe the four cases when the Hitchin fibration
on a $2$-dimensional moduli space of irregular Higgs bundles over
$\mathbb{C}P^{1}$ has a single singular fiber. The case when the fiber at
infinity is of type $I_0^*$ is further analyzed, and we give constructions of
all the possible configurations of singular curves inelliptic fibrations having
this type of singular fiber at infinity.

We study a class of quantum channels arising from the representation theory
of compact quantum groups that we call Temperley-Lieb quantum channels. These
channels simultaneously extend those introduced in [BC18], [AN14], and [LS14].
(Quantum) Symmetries in quantum information theory arise naturally from many
points of view, providing an important source of new examples of quantum
phenomena, and also serve as useful tools to simplify or solve important
problems. This work provides new applications of quantum symmetries in quantum
information theory. Among others, we study entropies and capacitites of
Temperley-Lieb channels, their (anti-)degradability, PPT and entanglement
breaking properties, as well as the behaviour of their tensor products with
respect to entangled inpurs. Finally we compare the Tempereley-Lieb channels
with the (modified) TRO-channels recently introduced in [GJL16].

Quantum Information is a new area of research which has been growing rapidly
since the last decade. This topic is very close to potential applications to
the so called Quantum Computer. In our point of view it makes sense to develop
a more "dynamical point of view" of this theory. We want to consider the
concepts of entropy and pressure for "stationary systems" acting on density
matrices which generalize the usual ones in Ergodic Theory (in the sense of the
Thermodynamic Formalism of R. Bowen, Y. Sinai and D. Ruelle). We consider the
operator $\mathcal{L}$ acting on density matrices $\rho\in \mathcal{M}_N$ over
a finite $N$-dimensional complex Hilbert space $\mathcal{L}(\rho):=\sum_{i=1}^k
tr(W_i\rho W_i^*)V_i\rho V_i^*,$ where $W_i$ and $V_i$, $i=1,2,... k$ are
operators in this Hilbert space. $\mathcal{L}$ is not a linear operator. In
some sense this operator is a version of an Iterated Function System (IFS).
Namely, the $V_i (.) V_i^*=:F_i(.)$, $i=1,2,...,k$, play the role of the
inverse branches (acting on the configuration space of density matrices $\rho$)
and the $W_i$ play the role of the weights one can consider on the IFS. We also
analyze the discrete Wigner function.
We suppose that for all $\rho$ we have that $\sum_{i=1}^k tr(W_i\rho
W_i^*)=1$. A family $W:=\{W_i\}_{i=1,..., k}$ determines a Quantum Iterated
Function System (QIFS) $\mathcal{F}_{W}$,
$\mathcal{F}_W=\{\mathcal{M}_N,F_i,W_i\}_{i=1,..., k}.$

Historical linguists have identified regularities in the process of historic
sound change. The comparative method utilizes those regularities to reconstruct
proto-words based on observed forms in daughter languages. Can this process be
efficiently automated? We address the task of proto-word reconstruction, in
which the model is exposed to cognates in contemporary daughter languages, and
has to predict the proto word in the ancestor language. We provide a novel
dataset for this task, encompassing over 8,000 comparative entries, and show
that neural sequence models outperform conventional methods applied to this
task so far. Error analysis reveals variability in the ability of neural model
to capture different phonological changes, correlating with the complexity of
the changes. Analysis of learned embeddings reveals the models learn
phonologically meaningful generalizations, corresponding to well-attested
phonological shifts documented by historical linguistics.

Didn't have loops for duvet cover
Everything about this comforter is perfect except for the fact that the one I got doesn't have any loops for connecting it to a duvet cover, so it's bunching up in the cover pretty immediately. I don't know if I got a defect or what, but it would be perfect with loops.

It is shown in the work of one of the authors in 1979 (MKV) that the
contribution to the amplitude of this decay from diagrams with one baryon loop
is equal to zero and contributions from diagrams with meson loops appear very
small. However, pole diagrams with intermediate vector mesons were not
considered there. Here it is shown that contributions of these pole diagrams
dominate. The meson-baryon chiral model used here is compared with known quark
chiral models. The obtained results are in satisfactory agreement with recent
experimental data.

There are now many known exoplanets with Msin(i) within a factor of two of
Neptune's, including the transiting planets GJ436b and HAT-P-11b. Planets in
this mass-range are different from their more massive cousins in several ways
that are relevant to their radiative properties and thermal structures. By
analogy with Neptune and Uranus, they are likely to have metal abundances that
are an order of magnitude or more greater than those of larger, more massive
planets. This increases their opacity, decreases Rayleigh scattering, and
changes their equation of state. Furthermore, their smaller radii mean that
fluxes from these planets are roughly an order of magnitude lower than those of
otherwise identical gas giant planets. Here, we compute a range of plausible
radiative equilibrium models of GJ436b and HAT-P-11b. In addition, we explore
the dependence of generic Neptune-mass planets on a range of physical
properties, including their distance from their host stars, their metallicity,
the spectral type of their stars, the redistribution of heat in their
atmospheres, and the possible presence of additional optical opacity in their
upper atmospheres.

Thumbnails are widely used all over the world as a preview for digital
images. In this work we propose a deep neural framework to generate thumbnails
of any size and aspect ratio, even for unseen values during training, with high
accuracy and precision. We use Global Context Aggregation (GCA) and a modified
Region Proposal Network (RPN) with adaptive convolutions to generate thumbnails
in real time. GCA is used to selectively attend and aggregate the global
context information from the entire image while the RPN is used to predict
candidate bounding boxes for the thumbnail image. Adaptive convolution
eliminates the problem of generating thumbnails of various aspect ratios by
using filter weights dynamically generated from the aspect ratio information.
The experimental results indicate the superior performance of the proposed
model over existing state-of-the-art techniques.

Trump and his sycophants are lying, of course. Just the estate tax repeal - all by itself - will benefit only the very wealthy. Some on here are lying that small estates are taxed now, but they aren't, of course. The estate tax kicks in only after $11 million for couples and $5.5 million for individuals.
Trump and his worshipers use lying as their primary tool because they have nothing else to work with. Trump needs to be removed from office.

PAHs have been detected toward molecular clouds and some young stars with
disks, but have not yet been associated with embedded young stars. We present a
sensitive mid-IR spectroscopic survey of PAH features toward a sample of
low-mass embedded YSOs. The aim is to put constraints on the PAH abundance in
the embedded phase of star formation using radiative transfer modeling.
VLT-ISAAC L-band spectra for 39 sources and Spitzer IRS spectra for 53
sources are presented. Line intensities are compared to recent surveys of
Herbig Ae/Be and T Tauri stars. The radiative transfer codes RADMC and RADICAL
are used to model the PAH emission from embedded YSOs consisting of a PMS star
with a circumstellar disk embedded in an envelope. The dependence of the PAH
feature on PAH abundance, stellar radiation field, inclination and the
extinction by the surrounding envelope is studied.
The 3.3 micron PAH feature is undetected for the majority of the sample
(97%), with typical upper limits of 5E-16 W/m^2. Compact 11.2 micron PAH
emission is seen directly towards 1 out of the 53 Spitzer Short-High spectra,
for a source that is borderline embedded. For all 12 sources with both VLT and
Spitzer spectra, no PAH features are detected in either. In total, PAH features
are detected toward at most 1 out of 63 (candidate) embedded protostars (<~
2%), even lower than observed for class II T Tauri stars with disks (11-14%).
Assuming typical class I stellar and envelope parameters, the absence of PAHs
emission is most likely explained by the absence of emitting carriers through a
PAH abundance at least an order of magnitude lower than in molecular clouds but
similar to that found in disks. Thus, most PAHs likely enter the protoplanetary
disks frozen out in icy layers on dust grains and/or in coagulated form.

Ten minutes worth of story stretched out into the better part of two hours. When nothing of any significance had happened at the halfway point I should have left. But, ever hopeful, I stayed. And left with a feeling of guilt for having wasted the time. Acting was OK, but the story line is so transparent and weak. The script is about as lame as it could get, but again, stretching out the ten minute plot doesn't leave a whole lot of room for good dialogue.

The class of antiperovskite compounds $A_3B$O ($A$ = Ca, Sr, Ba; $B$ = Sn,
Pb) has attracted interest as a candidate 3D Dirac system with topological
surface states protected by crystal symmetry. A key factor underlying the rich
electronic structure of $A_3B$O is the unusual valence state of $B$, i.e., a
formal oxidation state of $-4$. Practically, it is not obvious whether anionic
$B$ can be stabilized in thin films, due to its unusual chemistry, as well as
the polar surface of $A_3B$O, which may render the growth-front surface
unstable. We report X-ray photoelectron spectroscopy (XPS) measurements of
single-crystalline films of Sr$_3$SnO and Sr$_3$PbO grown by molecular beam
epitaxy (MBE). We observe shifts in the core-level binding energies that
originate from anionic Sn and Pb, consistent with density functional theory
(DFT) calculations. Near the surface, we observe additional signatures of
neutral or cationic Sn and Pb, which may point to an electronic or atomic
reconstruction with possible impact on putative topological surface states.

Topologically, a compact Riemann surface $X$ of genus $g$ is a $g$-holed
torus (a sphere with $g$ handles). This paper is an introduction to the theory
of compact Riemann surfaces and algebraic curves. It presents the basic ideas
and properties as an expository essay, explores some of their numerous
consequences and gives a concise account of the elementary aspects of different
viewpoints in curve theory. We discuss and prove most intuitively some
geometric-topological aspects of the algebraic functions and the associated
Riemann surfaces. Abelian and normalized differentials, Riemann's bilinear
relations and the period matrix for $X$ are defined and some consequences
drawn. The space of holomorphic 1-forms on $X$ has dimension $g$ as a complex
vector space. Fundamental results on divisors on compact Riemann surfaces are
stated and proved. The Riemann-Roch theorem is of utmost importance in the
algebraic geometric theory of compact Riemann surfaces. It tells us how many
linearly independent meromorphic functions there are having certain
restrictions on their poles. We present a simple direct proof of this theorem
and explore some of its numerous consequences. We also give an analytic proof
of the Riemann-Hurwitz formula. As an application, we compute the genus of some
interesting algebraic curves. Abel's theorem classifies divisors by their
images in the jacobian. The Jacobi inversion problem askes whether we can find
a divisor that is the preimage for an arbitrary point in the jacobian. In the
first appendix, we introduced intuitively and explicitly elliptic and
hyperelliptic Riemann surfaces. In the second appendix, we study some results
of resultant and discriminant as needed in the paper.

I compare two holographic mechanisms giving to the graviton a
parametrically-small supersymmetric mass $m_g$ in Anti-de Sitter spacetime. In
the context of bi-metric gravity these mechanisms couple `weakly' two initially
decoupled superconformal theories by: (i) turning on a double-trace
deformation, or (ii) gauging a common global symmetry. Superconformal
invariance restricts the number of Poincar\'e supercharges to $N_Q\leq 4$ for
mechanism (i) and to $N_Q\leq 8$ for mechanism (ii), and the AdS dimension to
$D\leq 5$. The putative effective supergravities are expected to break down in
the $m_g\to 0$ limit at an intermediate scale between $ m_g$ and $m_{\rm
Planck}$. In a recently-proposed microscopic embedding of mechanism (ii) in
string theory I show that $m_g=0$ is at infinite distance in moduli space, and
I relate the breakdown of the effective theory to the condensation of
unprotected spin-2 excitations in the string-theoretic description of the
`holographic bridge'. The phenomenon is invisible in the weakly-coupled CFT
side. I conjecture that similar phenomena should be at work in all cases.

We have employed the GMRT and the VLA to map the Lockman Hole. At 610 and
1,400 MHz, we reach noise levels of 15 and 6 uJy/beam, respectively, with
well-matched resolutions (~5"). At this depth we obtained reliable detections
for about half of the known submm galaxies (SMGs) in the field. For
radio-identified SMGs, which are typically at z ~ 2, we measure a mean radio
spectral index of alpha = -0.75 +/- 0.06 and standard deviation of 0.29,
between rest-frame ~1.8 and ~4.2 GHz. The slope of their continuum emission is
indistinguishable from that of local star-forming galaxies and suggests that
extended optically-thin synchrotron emission dominates the radio output of
SMGs. Cooling effects by synchrotron emission and Inverse Compton scattering
off the CMB do not seem to affect their radio SEDs. For those SMGs judged by
Spitzer mid-IR colours and spectroscopy to host obscured AGN, we find a clear
deviation from the rest of the sample - they typically have steeper radio
spectral indices, alpha ~< -1.0. These findings suggest these
mid-IR-/AGN-selected SMGs may have an intrinsically different injection
mechanism for relativistic particles, or they might reside in denser
environments. This work provides a reliable spectral template for the
estimation of far-IR/radio photometric redshifts, and will enable accurate
statistical K-corrections for the large samples of SMGs expected with SCUBA-2
and Herschel.

Some might remember if having seen the film Juno a scene where Ellen Page has a moment of praise for Dario Argento's Suspiria, her favorite horror film. Jason Bateman's character then asks if she's ever seen a Herschel Gordon Lewis film, and to wit he has a copy of a movie (I forget which at the moment) and shows it to her. At the time I saw Juno I had seen Suspiria and a few Argento films but not Lewis. Now I can see that it's not just another one of Diablo Cody's pop-culture "in" references, but something that actually is an indicator on the tastes of the characters and, maybe more subjectively, how to judge them based on their tastes. In other words, Herschel Gordon Lewis's reputation is maintained some many years after he ended making his gore films - and it's that of a schlock-Meister, no more no less. Actually, less.<br /><br />It's interesting then to take Argento as a basis of comparison, because both filmmakers approach, at least in the case of The Gore Gore Girls and, well, any given Argento picture, similar material. Where Argento is extraordinarily conscious about his craft, getting an audience wrapped up in whatever little story there is by the power of the movement of camera and music and style, Lewis takes the easy route to get at an audience, which is with an immature script and (putting it lightly) lackluster direction. The Gore Gore Girls reveals a filmmaker who isn't interested in entertaining his audience in an actual compelling way as a horror film, but as a side-show or a brothel. He can't direct actors worth a damn, he lights like it's a porno movie, and for every one possibly clever or funny one-liner there's ten that either totally stink or are too clever by half or not clever nearly enough.<br /><br />That being said, perhaps as the best substantive thing to say about The Gore Gore Girls, a mystery movie about a detective (2nd rate Sherlock Holmes guy played by somewhat amusing Frank Kress) and a newspaper reporter (dummie Amy Farrell) investigating a series of murders of go-go dancers, is that it serves as the template for countless more Troma-style pictures. Perhaps this is faint praise, however, and really the best thing that can truly be said is that Henny Youngman- "Take my wife, please!"- has a few scenes and steals every one of them without having to try much. It's sad, since it could be the kind of picture that could entertain on an awesomely-bad level. But even on that score one may laugh more out of embarrassment for the production, some of the actors (i.e. that guy who plays the cop, my God) than out of some guilty pleasure enjoyment.<br /><br />Even the gore itself is somewhat of a letdown. At first one thinks that Lewis is at least delivering on this end, showing these women being murdered in crazy and vicious and exaggerated ways. But with the killings it all goes on longer than necessary; I don't mean this in terms of shock value, for that it's fine. But there needs to be something else to really make it "stick", that showing women's faces dissected and eyes gouged is fine if you're 12 and seeing this as one of you're first 'horror' films. It becomes, dare I say it, dull. Dangerously dull for such a "daring" so-called movie.<br /><br />This was Lewis's last film until 30 years later an apparently worthy swan song came with a sequel to a film he made earlier brought him out of his retirement from movies and job in writing books on how to make it in business. However, whatever experience he had coming up to this one doesn't show. It's not a failure, but it could have been, and it's just simply... schlock. Take it or leave it.

I still have static cling
I wanted to love these but my laundry is still coming out with static cling. I don't notice my clothes drying faster and some laundry comes out with lint from the balls. I still use them from time to time hoping my outcome will change but so far no luck with that.

Individual neurons in convolutional neural networks supervised for
image-level classification tasks have been shown to implicitly learn
semantically meaningful concepts ranging from simple textures and shapes to
whole or partial objects - forming a "dictionary" of concepts acquired through
the learning process. In this work we introduce a simple, efficient zero-shot
learning approach based on this observation. Our approach, which we call Neuron
Importance-AwareWeight Transfer (NIWT), learns to map domain knowledge about
novel "unseen" classes onto this dictionary of learned concepts and then
optimizes for network parameters that can effectively combine these concepts -
essentially learning classifiers by discovering and composing learned semantic
concepts in deep networks. Our approach shows improvements over previous
approaches on the CUBirds and AWA2 generalized zero-shot learning benchmarks.
We demonstrate our approach on a diverse set of semantic inputs as external
domain knowledge including attributes and natural language captions. Moreover
by learning inverse mappings, NIWT can provide visual and textual explanations
for the predictions made by the newly learned classifiers and provide neuron
names. Our code is available at
https://github.com/ramprs/neuron-importance-zsl.

This paper presents a hybrid real-time camera pose estimation framework with
a novel partitioning scheme and introduces motion averaging to monocular
Simultaneous Localization and Mapping (SLAM) systems. Breaking through the
limitations of fixed-size temporal partitioning in many conventional SLAM
pipelines, our approach significantly improves the accuracy of local bundle
adjustment by gathering spatially-strongly-connected cameras into each block.
With the dynamic initialization using intermediate computation values, \XL{we
improve the Levenberg-Marquardt solver to further enhance the efficiency of the
local optimization.} Moreover, the dense data association between blocks by our
co-visibility-based partitioning enables us to explore and implement motion
averaging to efficiently align the blocks globally, updating camera motion
estimations on-the-fly. Experiments on benchmarks convincingly demonstrate the
practicality and robustness of our proposed approach by significantly
outperforming conventional approaches.

In the present work, we investigate $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$
production from $\Lambda_b$ decay in a molecular scenario by using an effective
Lagrangian approach. We predict the ratio of the branching fraction of
$\Lambda_b \to P_c K$, which is weakly dependent on our model parameter. We
also find the ratios of the productions of the branching fractions of
$\Lambda_b \to P_c K$ and $P_c \to J/\psi p$ can be well interpreted in the
molecular scenario. Moreover, the estimated branching fractions of $\Lambda_b
\to P_c K$ are of order $10^{-6}$, which could be tested by further
measurements in LHCb Collaboration.

How about decommissioning the city and give it back to the aboriginals. I assume they lived their peacefully for generations before we moved in.
Lets just concentrate in southern Ontario and forget the barbaric and outdated economic model of forever growth. This is a abberation in mankind, working in places like TO is fine however in the north it is just is not feasible. Why delay the inevitable. Lets concentrate our human mass south of Barrie and leave the north to the loons, bears, and aboriginal people.

Very Nice But...........
I love the bar stools but after having them for less than 4 months silver balls started falling from one of them than it became wobbly so I sat it in a corner to avoid any further damage. Then about 3 months later the same thing started to happen with the other one very frustrating seeing that they are not used daily I use them maybe twice a week if that. They look really pretty but do not hold up well very disappointed seeing they didn't last anytime. I will give 5 stars on how they look but as stability I will have to give it a 1

Assuming regularity of the fixed subalgebra, any action of a finite group $G$
on a holomorphic VOA $V$ determines a gauge anomaly $\alpha \in \mathrm{H}^3(G;
\boldsymbol{\mu})$, where $\boldsymbol{\mu} \subset \mathbb{C}^\times$ is the
group of roots of unity. We show that under Galois conjugation $V \mapsto
{^\gamma V}$, the gauge anomaly transforms as $\alpha \mapsto
\gamma^2(\alpha)$. This provides an a priori upper bound of $24$ on the order
of anomalies of actions preserving a $\mathbb{Q}$-structure, for example the
Monster group $\mathbb{M}$ acting on its Moonshine VOA $V^\natural$. We
speculate that each field $\mathbb{K}$ should have a "vertex Brauer group"
isomorphic to $\mathrm{H}^3(\mathrm{Gal}(\bar{\mathbb{K}}/\mathbb{K});
\boldsymbol{\mu}^{\otimes 2})$. In order to motivate our constructions and
speculations, we warm up with a discussion of the ordinary Brauer group,
emphasizing the analogy between VOA gauging and quantum Hamiltonian reduction.

The problem of successfully simulating ionic fluids at low temperature and
low density states is well known in the simulation literature: using
conventional methods, the system is not able to equilibrate rapidly due to the
presence of strongly associated cation-anion pairs. In this manuscript we
present a numerical method for speeding up computer simulations of the
restricted primitive model (RPM) at low temperatures (around the critical
temperature) and at very low densities (down to $10^{-10}\sigma^{-3}$, where
$\sigma$ is the ion diameter). Experimentally, this regime corresponds to
typical concentrations of electrolytes in nonaqueous solvents. As far as we are
aware, this is the first time that the RPM has been equilibrated at such
extremely low concentrations. More generally, this method could be used to
equilibrate other systems that form aggregates at low concentrations.

Good Job Camera Pen
Spy pen arrived on time and was well packaged... While this pen is for a Christmas present for my son it does look brilliant and is very well made and packaged... All the accessories are present (including micro SD card) making this excellent value for money when compared to other similar products out there. I have been surprised by the quality of the images and videos, if you give it enough light the quality is easily on a par with my mobile phone. Even in relatively low light it performs well although (as in all photography) the image quality suffers. I tried it last night in a shopping center car park and in the High Street under street lighting, The image was quite clear enough to recognise faces as people walked past. Overall extremely happy with my purchase.

I don't like the protests either but I respect the freedom to do it. Folks that pay $300 of their good money for tickets aren't going to just walk out of a ball game. He has some strange things to affix himself to. He comes out of left field with rants about what makes him mad

This is a cartoon series where most of the action takes place in the human body where the actors are vitamins, viruses, blood cells etc. I will not try to explain it in more details, you will simply have to see it for yourself: You will not be disappointed.<br /><br />I remember watching this as a kid in the 80s (with Swedish voices). I have talked with a few people who were also children in the 80s and they loved it also! I must admit that the education-part of the episodes didn't get through to me at a conscious level but the whole idea of educating children while they have fun is wonderful. I have recently seen a few episodes; there is a humour and heart in it that is hard to find in other children programs nowadays.<br /><br />5/5

We use a point-matching approach to numerically compute the Casimir
interaction energy for a two perfect-conductor waveguide of arbitrary section.
We present the method and describe the procedure used to obtain the numerical
results. At first, our technique is tested for geometries with known solutions,
such as concentric and eccentric cylinders. Then, we apply the point-matching
technique to compute the Casimir interaction energy for new geometries such as
concentric corrugated cylinders and cylinders inside conductors with focal
lines.

We discuss quantum evolution of a decaying state in relation to a recent
experiment of Katz et al. Based on exact analytical and numerical solutions of
a simple model, we identify a regime where qubit retains coherence over a
finite time interval independently of the rates of three competing decoherence
processes. In this regime, the quantum decay process can be continuously
monitored via a ``weak'' measurement without affecting the qubit coherence.

I agree... Alberta is hurting right now but it has to be careful not to become the "deplorables" of Canada. Instead of turning on Notley they should be thinking over the last thirty years of spendthrift extravanganza when they could have been saving up some of that oil windfall like Norway... what do they have now...? $900 billion? Enough to employ everyone and keep improving the place. But.. are Albertans mature enough to self reflect on those years of Conservative rule?

Generalized quasi-topological gravities (GQTGs) are higher-curvature
extensions of Einstein gravity characterized by the existence of non-hairy
generalizations of the Schwarzschild black hole which satisfy
$g_{tt}g_{rr}=-1$, as well as for having second-order linearized equations
around maximally symmetric backgrounds. In this paper we provide strong
evidence that any gravitational effective action involving higher-curvature
corrections is equivalent, via metric redefinitions, to some GQTG. In the case
of theories involving invariants constructed from contractions of the Riemann
tensor and the metric, we show this claim to be true as long as (at least) one
non-trivial GQTG invariant exists at each order in curvature ---and extremely
conclusive evidence suggests this is the case in general dimensions. When
covariant derivatives of the Riemann tensor are included, the evidence provided
is not as definitive, but we still prove the claim explicitly for all theories
including up to eight derivatives of the metric as well as for terms involving
arbitrary contractions of two covariant derivatives of the Riemann tensor and
any number of Riemann tensors. Our results suggest that the physics of generic
higher-curvature gravity black holes is captured by their GQTG counterparts,
dramatically easier to characterize and universal. As an example, we map the
gravity sector of the Type-IIB string theory effective action in AdS$_5$ at
order $\mathcal{O}({\alpha^{\prime}}^3)$ to a GQTG and show that the
thermodynamic properties of black holes in both frames match.

The Rosen-Zener model for association of atoms in a Bose-Einstein condensate
is studied. Using a nonlinear Volterra integral equation, we obtain an analytic
formula for final probability of the transition to the molecular state for weak
interaction limit. Considering the strong coupling limit of high field
intensities, we show that the system reveals two different time-evolution
pictures depending on the detuning of the frequency of the associating field.
For both limit cases we derive highly accurate formulas for the molecular state
probability valid for the whole range of variation of time. Using these
formulas, we show that at large detuning regime the molecule formation process
occurs almost non-oscillatory in time and a Rosen-Zener pulse is not able to
associate more than one third of atoms at any time point. The system returns to
its initial all-atomic state at the end of the process and the maximal
transition probability is achieved when the field intensity reaches its peak.
In contrast, at small detuning the evolution of the system displays
large-amplitude oscillations between atomic and molecular populations. We find
that the shape of the oscillations in the first approximation is defined by the
field detuning only. Finally, a hidden singularity of the Rosen-Zener model due
to the specific time-variation of the field amplitude at the beginning of the
interaction is indicated. It is this singularity that stands for many of the
qualitative and quantitative properties of the model. The singularity may be
viewed as an effective resonance-touching.

We present the results of a mixed action approach, employing dynamical
twisted mass fermions in the sea sector and overlap valence fermions, with the
aim of testing the continuum limit scaling behaviour of physical quantities,
taking the pion decay constant as an example. To render the computations
practical, we impose for this purpose a fixed finite volume with lattice size
$L\approx1.3$ fm. We also briefly review the techniques we have used to deal
with overlap fermions.

When Bozievich first ran for his county commissioner position, he pointed proudly to helping to keep in operation the tiny Elmira post office. He used it as an example of being supportive of the mainly rural area he now represents. I have been wondering where that rural identity, and corresponding support for outlying refuse transfer stations, has evaporated. Perhaps the glitz and glamour of having an office in the urban core has made him myopic. He seems to have turned his fiscal focus toward overpaying pretty good manager Mokrohisky and figuring out a way, along with the lovable but bumbling Eugene city councilors, to finance a new government complex in downtown Eugene. Don't count your chickens before they hatch, Jay.

O_LIEmpirical studies predicting the effects of the climate crisis on biodiversity loss that take into account learning ability and sexual selection are currently lacking.
C_LIO_LIUsing the African butterfly Bicyclus anynana, which shows strong phenotypic plasticity (i.e., polyphenism) in response to temperature, we find that learning produces a maladaptive mate preference under climate warming.
C_LIO_LIWe first modelled climate warming scenarios and then showed experimentally that as temperature becomes an unreliable cue to the onset of the dry season, adult butterflies displayed the wet season rather than the dry season form.
C_LIO_LIFemale learning further suppressed their innate, adaptive sexual preference for dry season males. Instead, females learned to prefer a phenotype transiently present during the seasonal transition.
C_LIO_LIFemale fertility and longevity were also indirectly affected by learning, likely reducing female fitness following climate warming.
C_LIO_LIOur results emphasize the importance of sexual selection, learning, and their fitness consequences for understanding (mal)adaptation of natural populations to climate warming.

We construct an axion model for generating isocurvature fluctuations with
blue spectrum, n_{iso}=2-4, which is suggested by recent analyses of admixture
of adiabatic and isocurvature perturbations with independent spectral indices,
n_{ad} \ne n_{iso}. The distinctive feature of the model is that the spectrum
is blue at large scales while scale invariant at small scales. This is
naturally realized by the dynamics of the Peccei-Quinn scalar field.

Dark gray tells turn dark brown after first wash.
Towels made a huge mess in my washing machine. Savers came off everywhere and I'm going to have to deep clean to get it out. My lint trap was the same. And my dark grey towels came out dark brown! Washed as instructions directed. Really disappointed in the coloring on these towels.

The main theme of this work is a unifying algorithm,
\textbf{L}oop\textbf{L}ess \textbf{S}ARAH (L2S) for problems formulated as
summation of $n$ individual loss functions. L2S broadens a recently developed
variance reduction method known as SARAH. To find an $\epsilon$-accurate
solution, L2S enjoys a complexity of ${\cal O}\big( (n+\kappa) \ln
(1/\epsilon)\big)$ for strongly convex problems. For convex problems, when
adopting an $n$-dependent step size, the complexity of L2S is ${\cal O}(n+
\sqrt{n}/\epsilon)$; while for more frequently adopted $n$-independent step
size, the complexity is ${\cal O}(n+ n/\epsilon)$. Distinct from SARAH, our
theoretical findings support an $n$-independent step size in convex problems
without extra assumptions. For nonconvex problems, the complexity of L2S is
${\cal O}(n+ \sqrt{n}/\epsilon)$. Our numerical tests on neural networks
suggest that L2S can have better generalization properties than SARAH. Along
with L2S, our side results include the linear convergence of the last iteration
for SARAH in strongly convex problems.

We present results on the mass of the nucleon and the Delta using two
dynamical degenerate twisted mass quarks and the tree-level Symanzik improved
gauge action. The evaluation is performed at four quark masses corresponding to
a pion mass in the range of about 300-600 MeV on lattices of 2.1-2.7 fm. We
check for cut-off effects by evaluating these baryon masses on lattices of
spatial size 2.1 fm at beta=3.9 and beta=4.05 and on a lattice of 2.4 fm at
beta=3.8. The values we find are compatible within our statistical errors.
Lattice results are extrapolated to the physical limit using continuum chiral
perturbation theory. Performing a combined fit to our lattice data at beta=3.9
and beta=4.05 we find a nucleon mass of 964\pm 28 (stat.) \pm 8 (syst.) MeV.
The nucleon mass at the physical point provides an independent determination of
the lattice spacing. Using heavy baryon chiral perturbation theory at O(p^3) we
find a_{\beta=3.9}=0.0890\pm 0.0039(stat.) \pm 0.0014(syst.) fm, and
a_{\beta=4.05}= 0.0691\pm 0.0034(stat.) \pm 0.0010(syst.) fm, in good agreement
with the values determined from the pion decay constant. Isospin violating
lattice artifacts in the Delta-system are found to be compatible with zero for
the values of the lattice spacings used in this work. Performing a combined fit
to our lattice data at beta=3.9 and beta=4.05 we find for the masses of the
Delta^{++,-} and Delta^{+,0} 1316 \pm 60 (stat.) MeV and 1330 \pm 74 (stat.)
MeV respectively. We confirm that in the continuum limit they are also
degenerate.

We consider scheduling and resource allocation in long-term evolution (LTE)
networks across voice over LTE (VoLTE) and best-effort data users. The
difference between these two is that VoLTE users get scheduling priority to
receive their required quality of service. As we show, strict priority causes
data services to suffer. We propose new scheduling and resource allocation
algorithms to maximize the sum- or proportional fair (PF) throughout amongst
data users while meeting VoLTE demands. Essentially, we use VoLTE as an example
application with both a guaranteed bit-rate and strict application-specific
requirements. We first formulate and solve the frame-level optimization problem
for throughput maximization; however, this leads to an integer problem coupled
across the LTE transmission time intervals (TTIs). We then propose a TTI-level
problem to decouple scheduling across TTIs. Finally, we propose a heuristic,
with extremely low complexity. The formulations illustrate the detail required
to realize resource allocation in an implemented standard. Numerical results
show that the performance of the TTI-level scheme is very close to that of the
frame-level upper bound. Similarly, the heuristic scheme works well compared to
TTI-level optimization and a baseline scheduling algorithm. Finally, we show
that our PF optimization retains the high fairness index characterizing
PF-scheduling.

The heat capacity of low-dimensional spin systems is studied using
theoretical and numerical techniques. Keeping only two energy states, the
system is mapped onto the two -level-system (TLS) model. Using the low
temperature Lanczos method, it is confirmed that the behavior of $T_{M}$ and
the energy gap as functions of the control parameter is the same in the two
models studied; a conclusion that can probably be extrapolated to the general
case of any system that possesses an energy gap.
