The emission of FU Orionis objects in outburst has been identified as arising
in rapidly accreting protoplanetary disks, based on a number of observational
properties. A fundamental test of the accretion disk scenario is that the
differentially rotating disk spectrum should produce a variation of rotational
velocity with the wavelength of observation, as spectra taken at longer
wavelengths probe outer, more slowly rotating disk regions. Previous
observations of FU Ori have shown smaller rotation at near-infrared (~ 2.2
micron) wavelengths than observed at optical (~ 0.6 micron) wavelengths
consistent with the assumption of Keplerian rotation. Here we report a spectrum
from the Phoenix instrument on Gemini South which shows that differential
(slower) rotation continues to be observed out to ~ 5 micron. The observed
spectrum is well matched by the prediction of our accretion disk model
previously constructed to match the observed spectral energy distribution and
the differential rotation at wavelengths < 2.2 micron. This kinematic result
allows us to confirm our previous inference of a large outer radius (~ 1 AU)
for the rapidly accreting region of the FU Ori disk, which presents
difficulties for outburst models relying purely on thermal instability. While
some optical spectra have been interpreted to pose problems for the disk
interpretation of FU Ori, we show that the adjustment of the maximum effective
temperature of the disk model, proposed in a previous paper, greatly reduces
these difficulties.

We study how the charges of the black rings measured at the asymptotic
infinity are encoded in the near-horizon metric and gauge potentials,
independent of the detailed structure of the connecting region. Our analysis
clarifies how different sets of four-dimensional charges can be assigned to a
single five-dimensional object under the Kaluza-Klein reduction. Possible
choices are related by the Witten effect on dyons and by the large gauge
transformation in four and five dimensions, respectively.

Establishing semantic correspondence is a core problem in computer vision and
remains challenging due to large intra-class variations and lack of annotated
data. In this paper, we aim to incorporate global semantic context in a
flexible manner to overcome the limitations of prior work that relies on local
semantic representations. To this end, we first propose a context-aware
semantic representation that incorporates spatial layout for robust matching
against local ambiguities. We then develop a novel dynamic fusion strategy
based on attention mechanism to weave the advantages of both local and context
features by integrating semantic cues from multiple scales. We instantiate our
strategy by designing an end-to-end learnable deep network, named as Dynamic
Context Correspondence Network (DCCNet). To train the network, we adopt a
multi-auxiliary task loss to improve the efficiency of our weakly-supervised
learning procedure. Our approach achieves superior or competitive performance
over previous methods on several challenging datasets, including PF-Pascal,
PF-Willow, and TSS, demonstrating its effectiveness and generality.

We study the quantum transport through two specific atomtronic circuits: a
Y-junction and a ring-shaped condensate pierced by an effective magnetic flux.
We demonstrate that for bosons, the two circuits display Andreev-like
reflections. For the Y-junction, the transport depends on the coupling strength
of the Y-junction. For the ring-shaped condensate, the transport crucially
depends on the particle statistics. For interacting bosons we find that the
Aharonov-Bohm interference effect is absent. By breaking the translational
invariance of the ring, the flux dependence can be restored. A complementary
view of the problem is obtained through a specific non-equilibrium quench
protocol. We find that the steady-state is independent of the flux, however the
actual time-dynamics depends on the flux. The dynamics of the full closed
system can be fitted with an approximated open system approach. For all the
protocols we studied, we find striking differences in the dynamics of the
Bose-Hubbard model and the Gross-Pitaevskii equation.

This paper shows that Mustata-Nakamura's conjecture holds for pairs
consisting of a smooth surface and a multiideal with a real exponent over the
base field of positive characteristic. As corollaries, we obtain the ascending
chain condition of the minimal log discrepancies and of the log canonical
thresholds for those pairs. We also obtain finiteness of the set of the minimal
log discrepancies of those pairs for a fixed real exponent.

It’s called a “vote of no confidence” and it would be nothing new for a city plagued with corruption and malfeasance. Rene Mansho. Nestor Garcia. Rod Tam. Two of those three city council members resigned in disgrace. The other one was “promoted” to the Hawai‘i State Legislature. All three were involved in key decisions on rail transit. Just another day in the nei.

We study hyperbolic polyhedral surfaces with faces isometric to regular
hyperbolic polygons satisfying that the total angles at vertices are at least
$2\pi.$ The combinatorial information of these surfaces is shown to be
identified with that of Euclidean polyhedral surfaces with negative
combinatorial curvature everywhere. We prove that there is a gap between areas
of non-smooth hyperbolic polyhedral surfaces and the area of smooth hyperbolic
surfaces. The numerical result for the gap is obtained for hyperbolic
polyhedral surfaces, homeomorphic to the double torus, whose 1-skeletons are
cubic graphs.

We present a field-theoretic study of the critical Casimir force of the Ising
universality class in a $d$-dimensional ${L_\parallel^{d-1} \times L}$ slab
geometry with a finite aspect ratio $\rho = L/L_\parallel$ above, at, and below
$T_c$. The result of a perturbation approach at fixed dimension $d=3$ is
presented that describes the dependence on the aspect ratio in the range $\rho
\gtrsim 1/4$. Our analytic result for the Casimir force scaling function for
$\rho = 1/4$ agrees well with recent Monte Carlo data for the three-dimensional
Ising model in slab geometry with periodic boundary conditions above, at, and
below $T_c$.

Runner DOES NOT move
I have a runner in front of my sliding glass doors and I have tile floors and a pool. It's extremely important that when I come in from the pool, I don't go slipping on the tile. I've used the carpet/rug tape for this runner. It works great for a few weeks, but I also have 4 dogs that are also always on this runner. After they've run over it and twirled on it, the tape was coming up and no longer had any adhesive left on it. I bought this and the dogs still spin around on it and some of the sides will fold over from this, BUT the runner DOES NOT move. I simple fold the turned up sides back over and the rug stays put. Absolutely love this and don't know why I didn't get it sooner. Don't waste your money on carpet/rug tape when you have this option instead.

MASnI$_3$, an organometallic halide, has great potential in the field of
lead-free perovskite solar cells. Ultraviolet photons have been shown to
generate deep trapping electronic defects in mesoporous TiO$_2$-based
perovskite, affecting its performance and stability. In this study, the
structure, electronic properties, and optical properties of the cubic,
tetragonal, and hexagonal phases of MASnI$_3$ were studied using
first-principles calculations. The results indicate that the hexagonal phase of
MASnI$_3$ possesses a larger indirect band gap and larger carrier effective
mass along the \emph{c}-axis compared with the cubic and tetragonal phases.
These findings were attributed to the enhanced electronic coupling and
localization in the hexagonal phase. Moreover, the hexagonal phase exhibited
high absorption of ultraviolet photons and high transmission of visible
photons, particularly along the \emph{c}-axis. These characteristics
demonstrate the potential of hexagonal MASnI$_3$ for application in
multijunction perovskite tandem solar cells or as coatings in mesoporous
TiO$_2$-based perovskite solar cells to enhance ultraviolet stability and
photon utilization.

You do realize that when you sell high, you also end up buying high in the market.
Housing plays a critical part in the lives of every citizen who lives in this country. As property taxes are now based on market value assessments, you can expect it to go up as the value of your property goes up. Imagine how a senior on a fixed income is going to pay their property taxes just to stay in their homes. They'd be forced to move out of their house.
Young families will have to secure a large mortgage just so they can buy a place to live. Getting indebted for such a large amount of money and at a longer time is not a great way to start out.
Our governments need to be more cognizant of the tremendous effect that the cost of housing has on people's lives. Housing should not be open to foreign speculative investors. There are only downsides in the future.
It's already too late for the Vancouver market. People who bought high will not be willing to sell their house at a loss.

Using an approximation by a set-valued dynamical system, this paper studies a
class of non Markovian and non homogeneous stochastic processes on a finite
state space. It provides an unified approach to simulated annealing type
processes. It permits to study new models of vertex reinforced random walks and
new models of learning in games including Markovian fictitious play.

We describe a new data format for storing triangular, symmetric, and
Hermitian matrices called RFPF (Rectangular Full Packed Format). The standard
two dimensional arrays of Fortran and C (also known as full format) that are
used to represent triangular and symmetric matrices waste nearly half of the
storage space but provide high performance via the use of Level 3 BLAS.
Standard packed format arrays fully utilize storage (array space) but provide
low performance as there is no Level 3 packed BLAS. We combine the good
features of packed and full storage using RFPF to obtain high performance via
using Level 3 BLAS as RFPF is a standard full format representation. Also, RFPF
requires exactly the same minimal storage as packed format. Each LAPACK full
and/or packed triangular, symmetric, and Hermitian routine becomes a single new
RFPF routine based on eight possible data layouts of RFPF. This new RFPF
routine usually consists of two calls to the corresponding LAPACK full format
routine and two calls to Level 3 BLAS routines. This means {\it no} new
software is required. As examples, we present LAPACK routines for Cholesky
factorization, Cholesky solution and Cholesky inverse computation in RFPF to
illustrate this new work and to describe its performance on several commonly
used computer platforms. Performance of LAPACK full routines using RFPF versus
LAPACK full routines using standard format for both serial and SMP parallel
processing is about the same while using half the storage. Performance gains
are roughly one to a factor of 43 for serial and one to a factor of 97 for SMP
parallel times faster using vendor LAPACK full routines with RFPF than with
using vendor and/or reference packed routines.

Operation Inherent Resolve (OIR) is the U.S. military's operational name for the military intervention against the Islamic State of Iraq and Syria (ISIS, in the vernacular, Daesh), including both the campaign in Iraq and the campaign in Syria, which terminology is used to define the timeline of United States government military operations is based on the Committee on International Relations (now known as the U.S. House Committee on Foreign Affairs)?

I work under the assumption that my employer wants to pay me as little as possible and still retain my services. There's no "men who control the economy" who are setting wages based on the gender % of the workers. Truck drivers get paid more than early childhood educators because driving a truck is a lousy job that is vital to the survival any company that employs them- ECE, not so much. It's supply and demand. There's no conspiracy going on where a group of men are deciding which jobs are going to get paid more. It's not happening. And while there may have been cases where women were being paid less than a male counterpart for the same job that's just anecdotal and not reflective of our economy as a whole.

Core-collapse supernovae are powerful neutrino sources. The observation of a
future (extra-)galactic supernova explosion or of the relic supernova neutrinos
might provide important information on the supernova dynamics, on the supernova
formation rate and on neutrino properties. One might learn more about unknown
neutrino properties either from indirect effects in the supernova (e.g. on the
explosion or on in the r-process) or from modifications of the neutrino time or
energy distributions in a detector on Earth. Here we will discuss in particular
possible effects of CP violation in the lepton sector. We will also mention the
interest of future neutrino-nucleus interaction measurements for the precise
knowledge of supernova neutrino detector response to electron neutrinos.

In this paper, we deal with the containment control problem in presence of
antagonistic interactions. In particular, we focus on the cases in which it is
not possible to contain the entire network due to a constrained number of
control signals. In this scenario, we study the problem of selecting the nodes
where control signals have to be injected to maximize the number of contained
nodes. Leveraging graph condensations, we find a suboptimal and computationally
efficient solution to this problem, which can be implemented by solving an
integer linear problem. The effectiveness of the selection strategy is
illustrated through representative simulations.

In the present work we explain the hour-glass magnetic dispersion in
underdoped cuprates. The dispersion arises due to the Lifshitz-type magnetic
criticality. Superconductivity also plays a role, but the role is secondary. We
list six major experimental observations related to the hour-glass and explain
all of them. The theory provides a unified picture of the evolution of magnetic
excitations in various cuprate families, including "hour-glass" and
"wine-glass" dispersions and an emergent static incommensurate order. We
propose the Lifshitz spin liquid "fingerprint" sum rule, and show that the
latest data confirm the validity of the sum rule.

We give a formula for the modular operator and modular conjugation in terms
of matrix coefficients of corepresentations of a quantum group in the sense of
Kustermans and Vaes. As a consequence, the modular autmorphism group of a
unimodular quantum group can be expressed in terms of matrix coefficients. As
an application, we determine the Duflo-Moore operators for the quantum group
analogue of the normaliser of SU(1,1) in $SL(2,\mathbb{C}$).

Fermi transport of spinors can be precisely understood in terms of 2-spinor
geometry. By using a partly original, previously developed treatment of
2-spinors and classical fields, we describe the family of all transports, along
a given 1-dimensional timelike submanifold of spacetime, which yield the
standard Fermi transport of vectors. Moreover we show that this family has a
distinguished member, whose relation to the Fermi transport of vectors is
similar to the relation between the spinor connection and spacetime connection.
Various properties of the Fermi transport of spinors are discussed, and applied
to the construction of free electron states for a detector-dependent QED
formalism introduced in a previous paper.

We study the dc Josephson effect in a diffusive multilayered SF'FF'S
structure, where S is a superconductor and F,F' are different ferromagnets. We
assume that the exchange energies in the F' and F layers are different ($% h $
and $H$, respectively) and the middle F layer consists of two layers with
parallel or antiparallel magnetization vectors $M$. The $M$ vectors in the left
and right F' layers are generally not collinear to those in the F layer. In the
limit of a weak proximity effect we use a linearized Usadel equation. Solving
this equation, we calculate the Josephson critical current for arbitrary
temperatures, arbitrary thicknesses of the F' and F layers ($% L_{h}$ and
$L_{H}$) in the case of parallel and antiparallel $M$ orientations in the F
layer. The part of the critical current $I_{cSR}$ formed by the short-range
(SRC) singlet and S=0 triplet condensate components decays on a short length
$\xi_{H}=\sqrt{D/H}$, whereas the part $% I_{cLR}$ due to the long-range
triplet $|S|=1$ component (LRTC) decreases with increasing $L_{H}$ on the
length $\xi_{N}=\sqrt{D/\pi T}$. Our results are in agreement with the
experiment \cite{Birge}.

Given the centrality of regions in social movements, politics and public
administration we aim to quantitatively study inter- and intra-regional
communication for the first time. This work uses social media posts to first
identify contiguous geographical regions with a shared social identity and then
investigate patterns of communication within and between them. Our case study
uses over 150 days of located Twitter data from England and Wales. In contrast
to other approaches, (e.g. phone call data records or online friendship
networks) we have the message contents as well as the social connection. This
allows us to investigate not only the volume of communication but also the
sentiment and vocabulary. We find that the South-East and North-West regions
are the most talked about; regions tend to be more positive about themselves
than about others; people talk politics much more between regions than within.
This methodology gives researchers a powerful tool to study identity and
interaction within and between social-geographic regions.

Our universe may have formed via bubble nucleation in an eternally-inflating
background. Furthermore, the background may have a compact dimension--the
modulus of which tunnels out of a metastable minimum during bubble
nucleation--which subsequently grows to become one of our three large spatial
dimensions. Then the reduced symmetry of the background is equivalent to
anisotropic initial conditions in our bubble universe. We compute the
inflationary spectrum in such a scenario and, as a first step toward
understanding the effects of anisotropy, project it onto spherical harmonics.
The resulting spectrum exhibits anomalous multipole correlations, their
relative amplitude set by the present curvature parameter, which extend to
arbitrarily large multipole moments. This raises the possibility of future
detection, if slow-roll inflation does not last too long within our bubble. A
full understanding of the observational signal must account for the effects of
background anisotropy on photon free streaming, and is left to future work.

We study two reciprocal thermal effects in the ferromagnetic semiconductor
(Ga,Mn)As by scattering theory: domain wall motion induced by a temperature
gradient as well as heat currents pumped by a moving domain wall. The effective
out-of-plane thermal spin transfer torque parameter $P_Q \beta_{Q}$, which
governs the coupling between heat currents and a magnetic texture, is found to
be of the order of unity. Unpinned domain walls are predicted to move at speed
10 m/s in temperature gradients of the order 10 ${\rm K/ \mu m}$. The cooling
power of a moving domain wall only compensates the heating due to friction
losses at ultra-low domain wall velocities of about 0.07 m/s. The Seebeck
coefficient is found to be of the order 100-500 ${\rm \mu V / K}$ at T=10 K, in
good agreement with recent experiment.

$\textit{Magic: The Gathering}$ is a popular and famously complicated trading
card game about magical combat. In this paper we show that optimal play in
real-world $\textit{Magic}$ is at least as hard as the Halting Problem, solving
a problem that has been open for a decade. To do this, we present a methodology
for embedding an arbitrary Turing machine into a game of $\textit{Magic}$ such
that the first player is guaranteed to win the game if and only if the Turing
machine halts. Our result applies to how real $\textit{Magic}$ is played, can
be achieved using standard-size tournament-legal decks, and does not rely on
stochasticity or hidden information. Our result is also highly unusual in that
all moves of both players are forced in the construction. This shows that even
recognising who will win a game in which neither player has a non-trivial
decision to make for the rest of the game is undecidable. We conclude with a
discussion of the implications for a unified computational theory of games and
remarks about the playability of such a board in a tournament setting.

There are some good things about the movie. The music and cinematography is great. Alex Wilson is hot and gives a great performance. Ryan Bauer is also hot. The production was very lucky to have casted them because they really give production value to the movie. Jonny Vincent (Sean) and a lot of the boys in the movie that don't speak are cute too. Why isn't the actress who plays Amy listed in the credits? Brandon Alexander gives a great comedic performance as Clitarissa Pink.<br /><br />The worse thing about the movie is probably the star, James Townsend. He can't act. He's also very scrawny, not nice to look at at all. His arms are like spaghetti. It's disgusting. They have no muscle tone at all. It's no wonder he has to make his own movie and cast himself in it. No one else would cast him in anything.<br /><br />James Townsend is not believable as someone who would even have a girlfriend because he acts so gay. They should have casted someone else as the lead if they wanted what's best for the movie. Then again, maybe he just wants to use this movie as a vehicle to launch a career in soft-core porn, definitely not real acting because he would have taken some acting lessons. Plus, anyone who does porn is blacklisted in Hollywood.<br /><br />The most ridiculous thing about the movie is probably the casting of a tan-skinned Latina as Devon's mother. Sonja Fisher does not seem like an actress at all. All in all, this movie is soft-core porn and is no better than something you would see on Skinemax. I think even Alex Wilson, probably the best thing about this movie, is embarrassed by it and doesn't want to be associated with it. There is no photo on his IMDb page and nothing else listed, so Alex Wilson is probably a disposable stage name. Plus, I ran into him in West Hollywood one time recently and when I mentioned this movie, he just turned around and walked away. I understand. If I had worked on this movie, I would be embarrassed and wouldn't want to be associated with it either.

So far, without breaking-in the speakers by running them for many hours, they seem to do a nice job in home theater use but if you are looking for something to use strictly for 2.1/stereo use, it might be better to spend a little more money and purchase some Polk floorstanding speakers instead.

Total bans are always the easy road to take in complicated situations. But it is usually the wrong road. As the dangers of asbestos have become known over the last 30 years its use in construction and materials has plummeted. It now remains mainly "locked up" between the walls of old buildings as insulation. It is harmful if inhaled, but just as cigarettes are safe as long as they remain in the packet, so asbestos in old buildings is safe if sealed and left alone. Banning asbestos would inevitably lead to a surge in removal from old buildings that could increase, rather than decrease, exposure to workers. Better to keep tightening the regulations on new use and safely and slowly remove old asbestos in small quantities as necessary.

The problem of generalized function matching can be defined as follows: given
a pattern $p=p_1 \cdots p_m$ and a text $t=t_1 \cdots t_n$, find a mapping
$f:\Sigma_p\rightarrow\Sigma_t^{*}$ and all text locations $i$ such that
$f(p_1) f(p_2) \cdots f(p_m) = t_i \cdots t_j$, a substring of $t$.
By modifying the restrictions of the matching function $f$, one can obtain
different matching problems, many of which have important applications. When
$f:\Sigma_p\rightarrow\Sigma_t$ we are faced with problems found in the
well-established field of combinatorial pattern matching. If the single
character constraint is lifted and $f:\Sigma_p\rightarrow\Sigma_t^{*}$, we
obtain generalized function matching as introduced by Amir and Nor (JDA 2007).
If we further constrain $f$ to be injective, then we arrive at generalized
parametrized matching as defined by Clifford et al. (SPIRE 2009).
There are a number of important applications for pattern matching in
computational biology, text editors and data compression, to name a few.
Therefore, many efficient algorithms have been developed for a wide variety of
specific problems including finding tandem repeats in DNA sequences, optimizing
embedded systems by reusing code etc.
In this work we present a heuristic algorithm illustrating a practical
approach to tackling a variant of generalized function matching where
$f:\Sigma_p\rightarrow\Sigma_t^{+}$ and demonstrate its performance on
human-produced text as well as random strings.

The fully implicit method is the most commonly used approach to solve
black-oil problems in reservoir simulation. The method requires repeated
linearization of large nonlinear systems and produces ill-condi\-tioned linear
systems. We present a strategy to reduce computational time that relies on two
key ideas: (\textit{i}) a sequential formulation that decouples flow and
transport into separate subproblems, and (\textit{ii}) a highly efficient
Gauss--Seidel solver for the transport problems. This solver uses intercell
fluxes to reorder the grid cells according to their upstream neighbors, and
groups cells that are mutually dependent because of counter-current flow into
local clusters. The cells and local clusters can then be solved in sequence,
starting from the inflow and moving gradually downstream, since each new cell
or local cluster will only depend on upstream neighbors that have already been
computed. Altogether, this gives optimal localization and control of the
nonlinear solution process.
This method has been successfully applied to real-field problems using the
standard first-order finite volume discretization. Here, we extend the idea to
first-order dG methods on fully unstructured grids. We also demonstrate proof
of concept for the reordering idea by applying it to the full simulation model
of the Norne oil field, using a prototype variant of the open-source OPM Flow
simulator.

The relaxation dynamics of photoexcited quasiparticles of three-dimensional
(3D) Dirac semimetals are vital towards their application in high performance
electronic and optoelectronic devices. In this work, the relaxation dynamics of
photoexcited carriers of 3D Dirac semimetal Cd3As2 are investigated by
transient terahertz spectroscopy. The visible pump-THz probe spectroscopy
measurement shows clear biexponential decays with two characteristic time
constants. According to the pump-power and temperature dependence, these two
characteristic time constants are attributed to the electron phonon coupling
(1-4 ps) and anharmonic decay of hot coupled phonons to electronic uncoupled
phonons (2-9 ps), respectively. An anomalous electron-optical phonon coupling
reduction and a bottleneck slowing of hot optical phonons relaxation are
observed with higher excitation intensities similar to that in graphene. On the
other hand, the electron-optical phonon coupling can be enhanced due to the
phonon frequency broadening and softening at elevated lattice temperature.
Furthermore, the transient THz spectrum response is strongly modified by the
phonon assisted intraband absorption of hot carriers from a pure electronic
Drude model, which is evidenced by a characteristic THz absorption dip in the
transient THz absorption spectrum. This absorption dip is pinned by the
discrete optical phonon energy that assists the intraband transition enabled by
photoexcitation of hot carriers.

You would never know from reading this article, but the revenues generated by local private broadcasters have been falling, which is the main reason that Blais reduced their requirements to spend on Canadian content production. Meanwhile, the Trudeau government is giving the CBC an additional $675 million over five years. Note that the author has presented no suggestions as to how private broadcasters receiving less revenue can continue to spend the same amount of money on Canadian content and remain in business. They do not receive cheques from the federal government like the CBC does.

As was noted already by A. N. Kolmogorov, any random variable has a Bernoulli
component. This observation provides a tool for the extension of results which
are known for Bernoulli random variables to arbitrary distributions. Two
applications are provided here: i. an anti-concentration bound for a class of
functions of independent random variables, where probabilistic bounds are
extracted from combinatorial results, and ii. a proof, based on the Bernoulli
case, of spectral localization for random Schroedinger operators with arbitrary
probability distributions for the single site coupling constants. For a general
random variable, the Bernoulli component may be defined so that its conditional
variance is uniformly positive. The natural maximization problem is an optimal
transport question which is also addressed here.

Not sure if I'm referring to those who labeled this a video nasty or to the director..."Devil Hunter" sure is one bizarre 'horror' movie.<br /><br />The plot is a loosey goosey combo of superior films like "Cannibal Ferox" and "Cut and Run." Chick gets kidnapped in the 'jungle' by a 'tribe' of 'savages.' The jungle looks more like a park somewhere in Mexico. The tribe is like a group of hippies who walk around in Party City-style Halloween costume renditions of tribal garb. And the savages range in race from white to Asian to black to hispanic. I suppose Franco just grabbed anyone who looked even slightly ethnic for this romp.<br /><br />To make matters worse, this film has ultra-minimal gore, no real scares and a lot of unnecessary penis. Not fun. I can find something to like in just about any sleazy Italian or Euro-trash film; this one just fell WAY short.<br /><br />2 out of 10, kids.

In this paper we study the Hilbert scheme, Hilb(P), of equidimensional
locally Cohen-Macaulay codimension 2 subschemes, with a special look to
surfaces in P^4 and 3-folds in P^5, and the Hilbert scheme stratification H_{c}
of constant cohomology. For every (X) in Hilb(P) we define a number \delta_X in
terms of the graded Betti numbers of the homogeneous ideal of X and we prove
that 1 + \delta_X - \dim_{(X)} H_{c} and 1 + \delta_X - \dim T_{c} are
CI-biliaison invariants where T_{c} is the tangent space of H_{c} at (X). As a
corollary we get a formula for the dimension of any generically smooth
component of Hilb(P) in terms of \delta_X and the CI-biliaison invariant. Both
invariants are equal in this case.
Recall that, for space curves C, Martin-Deschamps and Perrin have proved the
smoothness of the ``morphism'', H_{c} -> E = isomorphism classes of graded
artinian modules, given by sending C onto its Rao-module. For surfaces X in P^4
we have two Rao-modules M_i and an induced extension b in Ext^2(M_2,M_1) and a
result of Horrocks and Rao saying that a triple D := (M_1,M_2,b) of modules M_i
of finite length and an extension b as above determine a surface X up to
biliaison. We prove that the corresponding ``morphism'', H_{c} -> V =
isomorphism classes of graded artinian modules M_i commuting with b, is smooth,
and we get a smoothness criterion for H_{c}. Moreover we get some smoothness
results for Hilb(P), valid also for 3-folds, and we give examples of obstructed
surfaces and 3-folds. The linkage result we prove in this paper turns out to be
useful in determining the structure and dimension of H_{c}, and for proving the
main biliaison theorem above.

If Spotify and Apple Music generate so little money for musicians, why do so many of them participate in it? Even with the loss from piracy, surely it would be better for Taylor Swift or Moby or AC/DC to just take in the money from regular sales as they did before.

I cannot for the life of me explain what the popularity of the children's television show, power rangers is all about.<br /><br />I never understood why unsuspecting children liked this show in the first place, since the characters seem so idiotic and not worth caring about whatsoever.<br /><br />The costumes look completely atrocious, like multi colored spandex that people wear to go to the gym.<br /><br />What exactly is the purpose of this show anyways, but for kids to learn how to fight to solve their problems? What is up with the awful hair cuts, and clothing on this show anyway? Not to mention this show is still playing on cable television, just to make money to teach kids how to fight each other when they disagree on a certain problem.<br /><br />There's far better entertainment for today's children, hopefully they aren't as gullible as kids of the 1990s who watched this show.<br /><br />Oh, and what is up with the homo erotic tension between the red and green rangers anyway?

The Rashba effect is fundamental to the physics of two-dimensional electron
systems and underlies a variety of spintronic phenomena. It has been proposed
that the formation of Rashba-type spin splittings originates microscopically
from the existence of orbital angular momentum (OAM) in the Bloch wave
functions. Here, we present detailed experimental evidence for this OAM-based
origin of the Rashba effect by angle-resolved photoemission (ARPES) and
two-photon photoemission (2PPE) experiments for a monolayer AgTe on Ag(111).
Using quantitative low-energy electron diffraction (LEED) analysis we determine
the structural parameters and the stacking of the honeycomb overlayer with
picometer precision. Based on an orbital-symmetry analysis in ARPES and
supported by first-principles calculations, we unequivocally relate the
presence and absence of Rashba-type spin splittings in different bands of AgTe
to the existence of OAM.

The rich structure of the Fourth Positive System (A-X) of carbon monoxide
accounts for many of the spectral features seen in long slit HST-STIS
observations of comets 153P/Ikeya-Zhang, C/2001 Q4 (NEAT), and C/2000 WM1
(LINEAR), as well as in the HST-GHRS spectrum of comet C/1996 B2 Hyakutake. A
detailed CO fluorescence model is developed to derive the CO abundances in
these comets by simultaneously fitting all of the observed A-X bands. The model
includes the latest values for the oscillator strengths and state parameters,
and accounts for optical depth effects due to line overlap and self-absorption.
The model fits yield radial profiles of CO column density that are consistent
with a predominantly native source for all the comets observed by STIS. The
derived CO abundances relative to water in these comets span a wide range, from
0.44% for C/2000 WM1 (LINEAR), 7.2% for 153P/Ikeya-Zhang, 8.8% for C/2001 Q4
(NEAT) to 20.9% for C/1996 B2 (Hyakutake). The subtraction of the CO spectral
features using this model leads to the first identification of a molecular
hydrogen line pumped by solar HI Lyman-beta longward of 1200A in the spectrum
of comet 153P/Ikeya-Zhang. (Abridged)

When it was announced the "King of Pop" was dead at age 50, a month before he was to start a series of live comeback shows at London's O2 Arena, it was a huge shock to millions of people around the world. He was, and will forever be one of the most talented voices and dancers in the music industry, and he will be missed terribly. I decided to remind myself how wonderful he was by watching what is considered by many to be not only Jackson's best video (and possibly song), but the greatest music video ever made, from director John Landis (An American Werewolf in London). The film opens with Michael and his Girl (Ola Ray) having their car breakdown, and after giving her a ring, the moon comes out and he turns into a werewolf. We then see Michael and his Girl watching this horror film in the cinema, she is scared and walks out, and Michael soon follows her, singing the iconic song. Soon enough the voice of Vincent Price comes on, and zombies start crawling out the earth and open coffins from the graveyard, and Michael and the Girl are obviously surrounded. She turns away, and Michael has become a zombie himself, and with all the other creatures they do the iconic dance, before he turns back into his normal self, at least for the chorus. The Girl runs into the near creepy house, blocks the doorway, but zombie Michael still manages to break through, and when he touches her she screams to see normal Michael say "what's the problem?" The film ends with him taking her home, and looking at us with evil eyes. Michael Jackson was number 14 on The 100 Greatest Pop Culture Icons, and he was number 6 on The Ultimate Pop Star, the Thriller album was number 4 on The 100 Greatest Albums, and this video was number 71 on The 100 Greatest Scary Moments, and it was number 1 on The 100 Greatest Pop Videos. Very good!

We present new constraints on the non-linear coupling parameter fnl with the
Wilkinson Microwave Anisotropy Probe (WMAP) data. We use an updated method
based on the spherical Mexican hat wavelet (SMHW) which provides improved
constraints on the fnl parameter. This paper is a continuation of a previous
work by Curto et al. where several third order statistics based on the SMHW
were considered. In this paper, we use all the possible third order statistics
computed from the wavelet coefficient maps evaluated at 12 angular scales. The
scales are logarithmically distributed from 6.9 arcmin to 500 arcmin. Our
analysis indicates that fnl is constrained to -18 < fnl < +80 at 95% confidence
level (CL) for the combined V+W WMAP map. This value has been corrected by the
presence of undetected point sources, which adds a positive contribution of
Delta_fnl = 6 +- 5. Our result excludes at ~99% CL the best-fitting value
fnl=87 reported by Yadav & Wandelt. We have also constrained fnl for the Q, V
and W frequency bands separately, finding compatibility with zero at 95 % CL
for the Q and V bands but not for the W band. We have performed some further
tests to understand the cause of this deviation which indicate that systematics
associated to the W radiometers could be responsible for this result. Finally
we have performed a Galactic North-South analysis for fnl. We have not found
any asymmetry, i.e. the best-fitting fnl for the northern pixels is compatible
with the best-fitting fnl for the southern pixels.

In this paper we propose an approach of obtaining of N-dimensional spherical
harmonics based exclusively on the methods of solutions of differential
equations and the use of the special functions properties. We deduce the
Laplace-Beltrami operator on the N-sphere, indicate some instructive relations
for the metric, and demonstrate the procedure of separation of the variables.
We show that the ordinary differential equations for every variable, except
one, can be reduced to the Schr\"odinger equation (SE) with the symmetric
P\"oschl-Teller (SPT) potential well by means of certain substitutions. We also
exhibit that the solutions of SE with SPT potential are expressed in terms of
the Gegenbauer polynomials. The eigenvalues of the Laplace-Beltrami operator
and the characteristic numbers of the spherical harmonics are obtained with the
use of the properties of the spectrum of SE with SPT potential. The spherical
harmonics are constructed as a product of the eigenfunctions of SE with SPT
potential multiplied by a easily computable factor function and expressed in
terms of the Gegenbauer polynomials. The work has a pedagogical character to
some extent.

As I have said before, I am NOT a fan of Tweety. He's just so aggravating I wish Sylvester would just eat him and get it over with.<br /><br />In this cartoon Sly is homeless once again and is back to feeding out of garbage cans. He spots a cruise ship leaving port nearby and decides to hop aboard when he spys Tweety is one of the passengers. <br /><br />The ship provides an adequate stage for the following hijinks and Sly desperately tries to catch the annoying bird and avoid seasickness. If only for once he's succeed by chewing and swallowing, thus finishing of the irritating Canary forever. But, as cartoons starring Tweety go, this one is quite good, but it's ALL thanks to that brilliant cat.

A methane line list for the HITEMP spectroscopic database, covering 0-13,400
cm$^{-1}$ ($>$746 nm), is presented. To create this compilation, ab initio line
lists of $^{12}$CH$_{4}$ from Rey et al. (2017) ApJ, 847, 105 (provided at
separate temperatures in the TheoReTS information system), are now combined
with HITRAN2016 methane data to produce a single line list suitable for
high-temperature line-by-line calculations up to 2000 K. An
effective-temperature interpolation model was created in order to represent
continuum-like features at any temperature of interest. This model is
advantageous to previously-used approaches that employ so-called
``super-lines'', which are suitable only at a given temperature and require
separate line lists for different temperatures. The resultant HITEMP line list
contains $\sim$32 million lines and is significantly more flexible than
alternative line lists of methane, while accuracy required for astrophysical or
combustion applications is retained. Comparisons against experimental
observations of methane absorption at high temperatures have been used to
demonstrate the accuracy of the new work. The line list includes both strong
lines and quasi-continuum features and is provided in the common user-friendly
HITRAN/HITEMP format, making it the most practical methane line list for
radiative transfer modeling at high-temperature conditions.

Lol, sorry "Tim," Phil Hutchinson is an engineer; I'm a lawyer. Your understanding of law is less-sophisticated than an LA Law view. As for "trolling," Mr. Hutchinson took public records and posted them. None of them were private. All of them reflected the truth. That's why what Mr. Hutchinson did is exactly what investigative reporters do. And since you actually appear to have no firsthand knowledge of these circumstances, and don't live here, perhaps it would be more productive for your to direct your attention to matters about which you have knowledge.

We study AdS-waves in the three-dimensional new theory of massive gravity
recently proposed by Bergshoeff, Hohm, and Townsend. The general configuration
of this type is derived and shown to exhibit different branches, with different
asymptotic behaviors. In particular, for the special fine tuning
$m^2=\pm1/(2l^2)$, solutions with logarithmic fall-off arise, while in the
range $m^2>-1/(2l^2)$, spacetimes with Schrodinger isometry group are admitted
as solutions. Solutions that are asymptotically AdS$_3$, both for
Brown-Henneaux and for the weakened boundary conditions, are also identified.
The metric function that characterizes the profile of the AdS-wave behaves as a
massive excitation on the spacetime, with an effective mass given by
$m_{eff}^2=m^2-1/(2l^2)$. For the critical value $m^2=-1/(2l^2)$, the value of
the effective mass precisely saturates the Breitenlohner-Freedman bound for the
AdS$_3$ space where the wave is propagating on. The analogies with the AdS-wave
solutions of topologically massive gravity are also discussed. Besides, we
consider the coupling of both massive deformations to Einstein gravity and find
the exact configurations for the complete theory, discussing all the different
branches exhaustively. One of the effects of introducing the Chern-Simons
gravitational term is that of breaking the degeneracy in the effective mass of
the generic modes of pure New Massive Gravity, producing a fine structure due
to parity violation. Another effect is that the zoo of exact logarithmic
specimens becomes considerably enlarged.

There was general agreement among the participants that the root causes of the accountability breakdowns are systemic in nature, complex, and will require leadership and alterations to the current models in each of the four interrelated areas to transition to an overall system that is more focused on protecting the public interest and, in that regard, accountability.

Urban sanitation infrastructure is inadequate in many low-income countries, leading to the presence of highly concentrated, uncontained fecal waste streams in densely populated areas. Combined with mechanisms of aerosolization, airborne transport of enteric microbes and their genetic material is possible in such settings but remains poorly characterized. We detected and quantified enteric pathogen-associated gene targets in aerosol samples near open wastewater canals (OWCs) or wastewater-impacted surface waters and control sites in La Paz, Bolivia; Kanpur, India; and Atlanta, USA via multiplex reverse-transcription qPCR (37 targets) and ddPCR (13 targets). We detected a wide range of enteric targets, some not previously reported in extramural urban aerosols, with more frequent detections of all enteric targets at higher densities in La Paz and Kanpur near OWCs. We report density estimates ranging up to 4.7 x 102 gc per m3air across all targets including heat stabile enterotoxigenic E. coli, C. jejuni, enteroinvasive E. coli/Shigella spp., Salmonella spp., norovirus, and Cryptosporidium spp. An estimated 25%, 76%, and 0% of samples containing positive pathogen detects were accompanied by culturable E. coli in La Paz, Kanpur, and Atlanta, respectively, suggesting potential for viability of enteric microbes at the point of sampling. Airborne transmission of enteric pathogens merits further investigation in cities with poor sanitation.
SYNOPSISWe detected and quantified molecular targets associated with important enteric pathogens in outdoor aerosols in cities with poor sanitation to assess the potential role of the aeromicrobiological pathway in enteric infection transmission in such settings.

We prove a continuation critereon for incompressible liquids with free
surface boundary. We combine the energy estimates of Christodoulou and Lindblad
with an analog of the estimate due to Beale, Kato, and Majda for the gradient
of the velocity in terms of the vorticity, and use this to show solution can be
continued so long as the second fundamental form and injectivity radius of the
free boundary, the vorticity, and one derivative of the velocity on the free
boundary remain bounded, assuming that the Taylor sign condition holds.

A method for solving cyclic block three-diagonal systems of equations is
generalized for solving a block cyclic penta-diagonal system of equations.
Introducing a special form of two new variables the original system is split
into three block pentagonal systems, which can be solved by the known methods.
As such method belongs to class of direct methods without pivoting.
Implementation of the algorithm is discussed in some details and the numerical
examples are present.

The Joint Milliarcsecond Pathfinder Survey (JMAPS) is a Department of Navy
bright star astrometric all-sky survey scheduled for launch in the 2012
timeframe. Mission objectives include a complete update of star positions for
the 2015 epoch to accuracy levels of 1 milliarcsecond (5 nano-radians) for
bright stars, as well as demonstration of 10 milliarcsecond attitude
determination capability and 50 milli-arcsecond attitude control on-orbit. In
the following paper, we describe the general instrument design and expected
performance. We also discuss the new mission capabilities enabled by the
unprecedented attitude determination accuracy of such an instrument, and focus
specifically on the application to long distance (50,000-100,00 km) formation
flying and solar system navigation.

Attracted squirrels
I only saw one hummingbird come to my feeder. But it was attractive, easy to use and held the liquid well. My problem was an insistent squirrel decided to climb on the feeder and drink the sugar water. His weight and movement caused the feeder to come crashing down on our deck. I am so disappointed, that I am considering buying another one.

As global greenhouse gas emissions continue to rise, the use of stratospheric
aerosol injection (SAI), a form of solar geoengineering, is increasingly
considered in order to artificially mitigate climate change effects. However,
initial research in simulation suggests that naive SAI can have catastrophic
regional consequences, which may induce serious geostrategic conflicts. Current
geo-engineering research treats SAI control in low-dimensional approximation
only. We suggest treating SAI as a high-dimensional control problem, with
policies trained according to a context-sensitive reward function within the
Deep Reinforcement Learning (DRL) paradigm. In order to facilitate training in
simulation, we suggest to emulate HadCM3, a widely used General Circulation
Model, using deep learning techniques. We believe this is the first application
of DRL to the climate sciences.

We investigate the homogeneous Dirichlet problem for the Fast Diffusion
Equation $u_t=\Delta u^m$, posed in a smooth bounded domain $\Omega\subset
\mathbb{R}^N$, in the exponent range $m_s=(N-2)_+/(N+2)<m<1$. It is known that
bounded positive solutions extinguish in a finite time $T>0$, and also that
they approach a separate variable solution $u(t,x)\sim (T-t)^{1/(1-m)}S(x)$, as
$t\to T^-$. It has been shown recently that $v(x,t)=u(t,x)\,(T-t)^{-1/(1-m)}$
tends to $S(x)$ as $t\to T^-$, uniformly in the relative error norm. Starting
from this result, we investigate the fine asymptotic behaviour and prove sharp
rates of convergence for the relative error. The proof is based on an entropy
method relying on a (improved) weighted Poincar\'e inequality, that we show to
be true on generic bounded domains. Another essential aspect of the method is
the new concept of "almost orthogonality", which can be thought as a nonlinear
analogous of the classical orthogonality condition needed to obtain improved
Poincar\'e inequalities and sharp convergence rates for linear flows.

The memory physics induced unknown offset of the channel is a critical and
difficult issue to be tackled for many non-volatile memories (NVMs). In this
paper, we first propose novel neural network (NN) detectors by using the
multilayer perceptron (MLP) network and the recurrent neural network (RNN),
which can effectively tackle the unknown offset of the channel. However,
compared with the conventional threshold detector, the NN detectors will incur
a significant delay of the read latency and more power consumption. Therefore,
we further propose a novel dynamic threshold detector (DTD), whose detection
threshold can be derived based on the outputs of the proposed NN detectors. In
this way, the NN-based detection only needs to be invoked when the error
correction code (ECC) decoder fails, or periodically when the system is in the
idle state. Thereafter, the threshold detector will still be adopted by using
the adjusted detection threshold derived base on the outputs of the NN
detector, until a further adjustment of the detection threshold is needed.
Simulation results demonstrate that the proposed DTD based on the RNN detection
can achieve the error performance of the optimum detector, without the prior
knowledge of the channel.

Oh lol! That read so funny! Listen. It isn't even your comment but if you're serious in your criticism of asking for a link well then this is how I feel about NOT linking and why.
Here's how it goes when writing a comment that you'd, kinda, want to be taken seriously. So like, ah, the way to do that is simply: link it. That gives us, your readers, an opportunity to read your research, give it even more consideration and then, maybe slowly, your status as always writing valued comments is gained.
If I'd see your name, w/that established credibility, I'd ALWAYS read your comment.

The people at ABC forgot to do their biographical research... so many scenes were just plain wrong! The actor playing JPII was very rigid, there was no personality there. It is very very obvious that this movie was on the bottom of the programming totem poll, the move is so low budget. The script is terrible. Conversations like: "You must follow the rules" "No, the people are starving." Lame. Plus, the movie was jumping like crazy from event to event in order to fit it into the two hours. Terrible! A better use of your time would be to watch a PBS documentary on JPII. Also, CBS put out a miniseries on JPII that is better than ABC by far. JPII was a wonderful man, and it bothers me to think that my grandkids might get a hold of this ABC movie and think that THAT is what he was really like!

Warning: I got Gillette Mach 3 razors in Gillette Mach 3 Turbo packaging :(
I just discovered that these razors are actually Gillette Mach3 that packaged in Gillette Mach 3 Turbo package.. When I first tried them i thought that the company has changed the design of the razor. I did not like it and it did not work well with me, however, I sucked it up & continued using it. When I was almost out of it & went to check the market for alternatives, I was shocked when I found out that I was deceived. This one that I bought from Amazon was a fraud. Gillette did not change the design. Amazon sold me Gillette Mach 3 instead of what I wanted Gillette Mach 3 Turbo!

The classical foundations of migration research date from the 1880s with
Ravenstein's Laws of migration, which represent the first comparative analyses
of internal migration. While his observations remain largely valid, the ensuing
century has seen considerable progress in data collection practices and methods
of analysis, which in turn has permitted theoretical advances in understanding
the role of migration in population redistribution. Coupling the extensive
range of migration data now available with these recent theoretical and
methodological advances, we endeavour to advance beyond Ravenstein's
understanding by examining the direction of population redistribution and
comparing the impact of internal migration on patterns of human settlement in
27 European countries. Results show that the overall redistributive impact of
internal migration is low in most European countries but the mechanisms differ
across the continent. In Southern and Eastern Europe migration effectiveness is
above average but is offset by low migration intensities, whereas in Northern
and Western Europe high intensities are absorbed in reciprocal flows resulting
in low migration effectiveness. About half the European countries are
experiencing a process of concentration toward urbanised regions, particularly
in Northern, Central and Eastern Europe, whereas countries in the West and
South are undergoing a process of population deconcentration. These results
suggest that population deconcentration is now more common than it was in the
1990s when counterurbanisation was limited to Western Europe. The results show
that 130 years on, Ravenstein's law of migration streams and counter-streams
remains a central facet of migration dynamics, while underlining the importance
of simple yet robust indices for the spatial analysis of migration.

"Paranormal State" is an interesting show for most paranormal believers. I enjoy watching what the "team" has to say and what they "find", however, I know that the entire show along with it's build ups and story lines are completely set up. They go to real haunted locations and I suspect that they speak with actual witnesses. I commonly feel as I watch it that I am not watching non-fiction but an actual movie that is contradictory to reality. I personally would not advise or recommend anyone to watch this show unless you are a basic scare seeker. <br /><br />Interesting show. Stick to "Ghost Hunters"

Pathetic... worse than a bad made-for-TV movie. I can't believe that Spacey and Freeman were in this flick. For some reason Morgan Freeman's character is constantly talking about and saying "pussy" when referring to NSync boy's girlfriend. Morgan Freeman calling women "pussy" is just awkward... What the hell were the people behind this film thinking? Too many plot holes to imagine combined with the horrid acting, confusing camera angles, a lame script and cheap background music made this movie absolutely unbearable.<br /><br />I rented this flop with low expectations.... but... well... it really sucked.

We present the first exact analytic result for all partonic channels
contributing to the total cross section for the production of a pair of heavy
flavors in hadronic collisions in NLO QCD. Our calculation is an essential step
in the derivation of the top quark pair production cross section at NNLO in
QCD, which is a cornerstone of the precision LHC program. Our results uncover
the analytical structures behind observables with heavy flavors at higher
orders. They also reveal surprising and non-trivial implications for kinematics
close to partonic threshold.

This paper is mainly concerned with the generalised principal eigenvalue for
time-periodic nonlocal dispersal operators. We first establish the equivalence
between two different characterisations of the generalised principal
eigenvalue. We further investigate the dependence of the generalised principal
eigenvalue on the frequency, the dispersal rate and the dispersal spread.
Finally, these qualitative results for time-periodic linear operators are
applied to time-periodic nonlinear KPP equations with nonlocal dispersal,
focusing on the effects of the frequency, the dispersal rate and the dispersal
spread on the existence and stability of positive time-periodic solutions to
nonlinear equations.

One of the best ways for developers to test and improve their skills in a fun
and challenging way are programming challenges, offered by a plethora of
websites. For the inexperienced ones, some of the problems might appear too
challenging, requiring some suggestions to implement a solution. On the other
hand, tagging problems can be a tedious task for problem creators. In this
paper, we focus on automating the task of tagging a programming challenge
description using machine and deep learning methods. We observe that the deep
learning methods implemented outperform well-known IR approaches such as
tf-idf, thus providing a starting point for further research on the task.

We report on a new x-ray imaging method, which combines the high spatial
resolution of coherent diffraction imaging with the ability of dark field
microscopy to map grains within thick polycrystalline specimens. An x-ray
objective serves to isolate a grain and avoid overlap of diffraction spots.
Iterative oversampling routines are used to reconstruct the shape and strain
field within the grain from the far field intensity pattern. The limitation on
resolution caused by the finite numerical aperture of the objective is overcome
by the Fourier synthesis of several diffraction patterns. We demonstrate the
method by an experimental study of a ~500 nm Pt grain for the two cases of a
real and a virtual image plane. In the latter case the spatial resolution is 13
nm rms. Our results confirm that no information on the pupil function of the
lens is required and that lens aberrations are not critical.

Uncomfortable shoes
These shoes look super cute but they are by far one of the most uncomfortable shoes I've ever owned.

We study the ground state properties of an anisotropic, quasi-2D version of
the quantum (S=1/2) pyrochlore antiferromagnet. In the presence of
Dzyaloshinsky-Moriya interactions, in addition to the Heisenberg exchanges, it
is shown that two types of ordered magnetic states are generally possible: non
coplanar "chiral," and coplanar antiferromagnetic order. The magnetic moments
in all cases are determined by the Dzyaloshinsky-Moriya interactions and in
this sense the antiferromagnetic order is "weak."

We consider the use of a pi-junction for flux qubits to realize degenerate
quantum levels without external magnetic field. On the basis of the
Caldeira-Leggett model, we derive an effective spin-Boson model, and study
decoherece of this type of qubits. We estimate the dephasing time by using
parameters from recent experiments of SIFS junctions, and show that high
critical current and large subgap resistance are required for the pi-junction
to realize a long coherent time.

Garbage
I tried to file a claim over the phone. I had already emailed the docs but but the representative told me to email in different documentation again. Afterwards, it was radio silence. The coverage was the same as if I'd paid for the replacement parts myself. They made it as difficult as possible to file a claim. I got an email this morning stating that these crooks lost a class action and I am eligible for a full refund when the case is concluded. Don't fall for this scam!

This is the first ever attempt of application in a country other than Italy
of a research efficiency indicator (FSS), to assess and compare the performance
of professors and universities, within and between countries. A special
attention has been devoted to the presentation of the methodology developed to
set up a common field classification scheme of professors, and to overcome the
limited availability of comparable input data. Results of the comparison
between countries, carried out in the 2011-2015 period, show similar average
performances of professors, but noticeable differences in the distributions,
whereby Norwegian professors are more concentrated in the tails. Norway shows
notable higher performance in Mathematics and Earth and Space Sciences, while
Italy in Biomedical Research and Engineering.

In the bibliography a certain confusion arises in what regards to the
classification of the gravitational theories into scalar-tensor theories and
general relativity with a scalar field either minimally or non-minimally
coupled to matter. Higher-derivatives Horndeski and beyond Horndeski theories
that at first sight do not look like scalar-tensor theories only add to the
confusion. To further complicate things, the discussion on the physical
equivalence of the different conformal frames in which a given scalar-tensor
theory may be formulated, makes even harder to achieve a correct
classification. In this paper we propose a specific criterion for an
unambiguous identification of scalar-tensor theories and discuss its impact on
the conformal transformations issue. The present discussion carries not only
pedagogical but also scientific interest since an incorrect classification of a
given theory as a scalar-tensor theory of gravity may lead to conceptual issues
and to the consequent misunderstanding of its physical implications.

The purpose of this paper is to study Hom-Lie superalgebras, that is a
superspace with a bracket for which the superJacobi identity is twisted by a
homomorphism. This class is a particular case of $\Gamma$-graded quasi-Lie
algebras introduced by Larsson and Silvestrov. In this paper, we characterize
Hom-Lie admissible superalgebras and provide a construction theorem from which
we derive a one parameter family of Hom-Lie superalgebras deforming the
orthosymplectic Lie superalgebra. Also, we prove a $\mathbb{Z}_2$-graded
version of a Hartwig-Larsson-Silvestrov Theorem which leads us to a
construction of a q-deformed Witt superalgebra.

Quantum ergodic restriction (QER) is the problem of finding conditions on a
hypersurface $H$ so that restrictions $\phi_j |_H$ to $H$ of
$\Delta$-eigenfunctions of Riemannian manifolds $(M, g)$ with ergodic geodesic
flow are quantum ergodic on $H$. We prove two kinds of results: First (i) for
any smooth hypersurface $H$, the Cauchy data $(\phi_j|H, \partial \phi_j|H)$ is
quantum ergodic if the Dirichlet and Neumann data are weighted appropriately.
Secondly (ii) we give conditions on $H$ so that the Dirichlet (or Neumann) data
is individually quantum ergodic. The condition involves the almost nowhere
equality of left and right Poincar\'e maps for $H$. The proof involves two
further novel results: (iii) a local Weyl law for boundary traces of
eigenfunctions, and (iv) an 'almost-orthogonality' result for Fourier integral
operators whose canonical relations almost nowhere commute with the geodesic
flow.

"It is why they express such deep and persistent reservations about establishing closer links with China, a country that does not respect the rule of law, or basic freedoms for artists, journalists, ethnic minorities and religious believers."
To be fair, disrespect for the rule of law, the media, and minorities were campaign pledges made by the president elect. We are going to have to get used to doing business with despotic regimes one way or another.

This paper proves the concept that it is feasible to accurately recognize
specific human mobility shared patterns, based solely on the connection logs
between portable devices and WiFi Access Points (APs), while preserving user's
privacy. We gathered data from the Eduroam WiFi network of Polytechnique
Montreal, making omission of device tracking or physical layer data. The
behaviors we chose to detect were the movements associated to the end of an
academic class, and the patterns related to the small break periods between
classes. Stringent conditions were self-imposed in our experiments. The data is
known to have errors noise, and be susceptible to information loss. No
countermeasures were adopted to mitigate any of these issues. Data
pre-processing consists of basic statistics that were used in aggregating the
data in time intervals. We obtained accuracy values of 93.7 % and 83.3 % (via
Bagged Trees) when recognizing behaviour patterns of breaks between classes and
end-of-classes, respectively.

The coronavirus disease 2019 (COVID-19) has been ravaging throughout the world for more than two years and has severely impaired both human health and the economy. The causative agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) employs the viral RNA-dependent RNA polymerase (RdRp) complex for genome replication and transcription, making RdRp an appealing target for antiviral drug development. Here, we reveal that RdRp can recognize and utilize nucleoside diphosphates (NDPs) as a substrate to synthesize RNAs with an efficiency of about two thirds of using nucleoside triphosphates (NTPs) as a substrate. NDPs incorporation is also template-specific and has high fidelity. Moreover, RdRp can incorporate {beta}-d-N4-hydroxycytidine (NHC) into RNA while using diphosphate form molnupiravir (MDP) as a substrate. We also observed that MDP is a better substrate for RdRp than the triphosphate form molnupiravir (MTP).

We discuss infrared Spitzer observations of early type galaxies in the SAURON
sample at 24, 60 and 170 microns. When compared with 2MASS Ks band
luminosities, lenticular (S0) galaxies exhibit a much wider range of mid to
far-infrared luminosities then elliptical (E) galaxies. Mid and far-infrared
emission from E galaxies is a combination of circumstellar or interstellar
emission from local mass-losing red giant stars, dust buoyantly transported
from the galactic cores into distant hot interstellar gas and dust accreted
from the environment. The source of mid and far-IR emission in S0 galaxies is
quite different and is consistent with low levels of star formation, 0.02 - 0.2
Msol/yr, in cold, dusty gaseous disks. The infrared 24micron-70micron color is
systematically lower for (mostly S0) galaxies with known molecular disks. Our
observations support the conjecture that cold dusty gas in some S0 galaxies is
created by stellar mass loss at approximately the same rate that it is consumed
by star formation, so the mass depletion of these disks by star formation will
be slow. Unlike E galaxies, the infrared luminosities of S0 galaxies correlate
with both the mass of molecular gas and the stellar Hbeta spectral index, and
all are related to the recent star formation rate. However, star formation
rates estimated from the Hbeta emission line luminosities L_{Hbeta} in SAURON
S0 galaxies are generally much smaller. Since L_{Hbeta} does not correlate with
24 microns emission from dust heated by young stars, optical emission lines
appear to be a poor indicator of star formation rates in SAURON S0 galaxies.
The absence of Hbeta emission may be due to a relative absence of OB stars in
the initial mass function or to dust absorption of Hbeta emission lines.

Topological superconductors have been theoretically predicted as a new class
of time-reversal-invariant superconductors which are fully gapped in the bulk
but have protected gapless surface Andreev bound states. In this work, we
provide a simple criterion that directly identifies this topological phase in
\textit{odd-parity} superconductors. We next propose a two-orbital $U-V$
pairing model for the newly discovered superconductor Cu$_x$Bi$_2$Se$_3$%. Due
to its peculiar three-dimensional Dirac band structure, we find that an
inter-orbital triplet pairing with odd-parity is favored in a significant part
of the phase diagram, and therefore gives rise to a topological superconductor
phase. Finally we propose sharp experimental tests of such a pairing symmetry.

The urgency of predictions in large-t region at LHC stimulated us to present
a unified model of small and high t scattering at high energies. Our model is
based upon a safe theoretical ground: analyticity, unitarity, Regge behavior,
gluon exchange and saturation of bounds established in axiomatic quantum field
theory. We make precise predictions for the behavior of the differential cross
sections at high t, the evolution of the dip-shoulder structure localized in
the region of -t between 0.5 and 0.8 GeV**2 and the radical violation of the
exponential behavior of the first diffraction cone at small t.

I was living in Barstow Ca. in 1968 when the movie The Killers Three arrived at the local theater. The trailer was enough to get me to pay my hard earned money to see this movie. I was really expecting a Bonnie And Clyde movie and I got Dick Clark playing a shy nerdy guy while Robert Walker and Diane Varsi played an poor attempt of reinacting Bonnie and Clyde. Needless to say it never went over well. Maybe this is why it never made it to video. Even as a kid I was left some what ripped off as I left the theater. After all the best parts where in the trailer of the movie. The movie was dull and pretty much pointless. By the way, Dick Clark gets killed so it wasn't a total let down.

Millimeter wave signals and large antenna arrays are considered enabling
technologies for future 5G networks. Despite their benefits for achieving high
data rate communications, their potential advantages for tracking of the
location of the user terminals are largely undiscovered. In this paper, we
propose a novel support detection-based channel training method for frequency
selective millimeter-wave (mm-wave) multiple-input-multiple-output system with
lens antenna arrays. We show that accurate position and orientation estimation
and tracking is possible using signals from a single transmitter with lens
antenna arrays. Particularly, the beamspace channel estimation is formulated as
two sparse signal recovery problems in the downlink and uplink for the
estimation of angle-of-arrival, angle-of-departure, and time-of-arrival. The
proposed method offers a higher sparse detection probability compared to the
compressed sensing based solutions. Finally, a joint heuristic beamformer
design and user position and orientation tracking approach are proposed based
on initial estimation of channel parameters obtained in the training phase.

The single stable isotope of beryllium is a pure product of cosmic-ray
spallation in the ISM. Assuming that the cosmic-rays are globally transported
across the Galaxy, the beryllium production should be a widespread process and
its abundance should be roughly homogeneous in the early-Galaxy at a given
time. Thus, it could be useful as a tracer of time. In an investigation of the
use of Be as a cosmochronometer and of its evolution in the Galaxy, we found
evidence that in a log(Be/H) vs. [alpha/Fe] diagram the halo stars separate
into two components. One is consistent with predictions of evolutionary models
while the other is chemically indistinguishable from the thick-disk stars. This
is interpreted as a difference in the star formation history of the two
components and suggests that the local halo is not a single uniform population
where a clear age-metallicity relation can be defined. We also found evidence
that the star formation rate was lower in the outer regions of the thick disk,
pointing towards an inside-out formation.

Great mechanical pencil
Gotta say, I love this pencil. I am a college student, and as someone would expect, I write a lot of notes. I've used this one pencil for a full year, every day, all day. And I'm nothing but impressed. The metal body helps a lot with the sturdiness of the pencil, as I can't tell you how many times I have accidentally broken my mechanical pencils by stepping on them, or them being crushed in my school backpack. Well, this has last a very long time compared to my other pencils I used. Someone reading this may be into other types of drawing and not like this review, but I understand. I'm praising this product for it's durability.

We propose and investigate new complementary methodologies for estimating
predictive variance networks in regression neural networks. We derive a locally
aware mini-batching scheme that result in sparse robust gradients, and show how
to make unbiased weight updates to a variance network. Further, we formulate a
heuristic for robustly fitting both the mean and variance networks post hoc.
Finally, we take inspiration from posterior Gaussian processes and propose a
network architecture with similar extrapolation properties to Gaussian
processes. The proposed methodologies are complementary, and improve upon
baseline methods individually. Experimentally, we investigate the impact on
predictive uncertainty on multiple datasets and tasks ranging from regression,
active learning and generative modeling. Experiments consistently show
significant improvements in predictive uncertainty estimation over
state-of-the-art methods across tasks and datasets.

Energy management, and in particular its optimization, is one of the hot
trends in the current days, both at the enterprise level (optimization of whole
corporate/government buildings) and single citizens' homes. The current trend
is to provide knowledge about the micro(scopic) energy consumption. This allows
to save energy, but also to optimize the dfferent energy sources (e.g., solar
vs. traditional one) in case of a mixed architecture. In this work, after
briefly introducing our specific platform for smart environments able to
micro-account energy consumption of devices, we present two case studies of its
utilization: energy saving in offices and smart switching among dfferent energy
sources.

I really wanted to like this, but I guess it’s just the luck ...
In the past I’ve had nothing but luck with Christmas cacti. This one seemed healthy when I received it, but after having it for a little over a week it already has died (I think) and all of its leaves and everything has fallen off. I really wanted to like this, but I guess it’s just the luck of the draw with plants. You never know how well they’re going to do

In this work I discuss the necessary steps for deriving photometric redshifts
for luminous red galaxies (LRGs) and galaxy clusters through simple empirical
methods. The data used is from the Sloan Digital Sky Survey (SDSS). I show that
with three bands only ({\it gri}) it is possible to achieve results as accurate
as the ones obtained by other techniques, generally based on more filters. In
particular, the use of the $(g-i)$ color helps improving the final redshifts
(especially for clusters), as this color monotonically increases up to $z \sim
0.8$. For the LRGs I generate a catalog of $\sim 1.5$ million objects at $z <
0.70$. The accuracy of this catalog is $\sigma = 0.027$ for $z \le 0.55$ and
$\sigma = 0.049$ for $0.55 < z \le 0.70$. The photometric redshift technique
employed for clusters is independent of a cluster selection algorithm. Thus, it
can be applied to systems selected by any method or wavelength, as long as the
proper optical photometry is available. When comparing the redshift listed in
literature to the photometric estimate, the accuracy achieved for clusters is
$\sigma = 0.024$ for $z \le 0.30$ and $\sigma = 0.037$ for $030 < z \le 0.55$.
However, when considering the spectroscopic redshift as the mean value of SDSS
galaxies on each cluster region, the accuracy is at the same level as found by
other authors: $\sigma = 0.011$ for $z \le 0.30$ and $\sigma = 0.016$ for $030
< z \le 0.55$. The photometric redshift relation derived here is applied to
thousands of cluster candidates selected elsewhere. I have also used galaxy
photometric redshifts available in SDSS to identify groups in redshift space
and then compare the redshift peak of the nearest group to each cluster
redshift (ABRIDGED).

Unmanned Aerial Vehicles (UAVs), equipped with camera sensors can facilitate
enhanced situational awareness for many emergency response and disaster
management applications since they are capable of operating in remote and
difficult to access areas. In addition, by utilizing an embedded platform and
deep learning UAVs can autonomously monitor a disaster stricken area, analyze
the image in real-time and alert in the presence of various calamities such as
collapsed buildings, flood, or fire in order to faster mitigate their effects
on the environment and on human population. To this end, this paper focuses on
the automated aerial scene classification of disaster events from on-board a
UAV. Specifically, a dedicated Aerial Image Database for Emergency Response
(AIDER) applications is introduced and a comparative analysis of existing
approaches is performed. Through this analysis a lightweight convolutional
neural network (CNN) architecture is developed, capable of running efficiently
on an embedded platform achieving ~3x higher performance compared to existing
models with minimal memory requirements with less than 2% accuracy drop
compared to the state-of-the-art. These preliminary results provide a solid
basis for further experimentation towards real-time aerial image classification
for emergency response applications using UAVs.

We extend Hardy's uncertainty principle for a square integrable function and
its Fourier transform to the multidimensional case using a symplectic
diagonalization. We use this extension to show that Hardy's uncertainty
principle is equivalent to a statement on the Wigner distribution of the
function. We give a geometric interpretation of our results in terms of the
notion of symplectic capacity of an ellipsoid. Furthermore, we show that
Hardy's uncertainty principle is valid for a general Lagrangian frame of the
phase space. Finally, we discuss an extension of Hardy's theorem for the Wigner
distribution for exponentials with convex exponents.

Yes, "peer review is a bad way to monitor the comment sections[,] Alaska Dispatch." Why I never reject any comments I'm supposed to "review." Don't read them...just check the boxes. Yes, I see where "The hate posts against the church are being put up on this comment section..." I'm sure you've included my previous comment in that category. However, I see no evidence that "the comment[s] taking up for the churches are being removed…" Your comment, Ms. Brown, and the comments of others making the complaint that "conservative" comments are being deleted or something...are actually posted rather routinely. I suspect that any comments "peer-reviewed" as "uncivil" are probably (I'm guessing here) reviewed by the rather chirpy representative from "Civil" for a final determination. My take is that Alaska Dispatch does not censor these online comments for content. I wouldn't like that. More "liberal" comments are being made. Or maybe the "conservative" comments are more "uncivil." I don't know.

We report the systematic analysis of the durations for Swift gamma-ray bursts
(GRBs) and compare the results with those of pre-Swift data. For 95 GRBs with
known redshift, we show that the observed durations have two lognormal
distributions that are clearly divided at $T_{90}\simeq2$ s. This is consistent
with the earlier BATSE results. The intrinsic durations also show a bimodal
distribution but shift systematically toward the smaller value and the
distribution exhibits a narrower width compared with the observed one. We find
that the intrinsic distributions of long GRBs between Swift and pre-Swift are
significantly different particularly in the width and the median value. In
addition, the Swift data exhibit a wider dynamic range of duration. Our present
study not only confirms the spectra of short GRBs are in general harder than
the long GRBs in the observer frame but also shows this trend becomes weaker in
the source frame.

Deep learning with convolutional neural networks (ConvNets) have dramatically
improved learning capabilities of computer vision applications just through
considering raw data without any prior feature extraction. Nowadays, there is
rising curiosity in interpreting and analyzing electroencephalography (EEG)
dynamics with ConvNets. Our study focused on ConvNets of different structures,
constructed for predicting imagined left and right movements on a
subject-independent basis through raw EEG data. Results showed that recently
advanced methods in machine learning field, i.e. adaptive moments and batch
normalization together with dropout strategy, improved ConvNets predicting
ability, outperforming that of conventional fully-connected neural networks
with widely-used spectral features.
