We present ALMA and MUSE observations of the Brightest Cluster Galaxy in
Abell 2597, a nearby (z=0.0821) cool core cluster of galaxies. The data map the
kinematics of a three billion solar mass filamentary nebula that spans the
innermost 30 kpc of the galaxy's core. Its warm ionized and cold molecular
components are ... |
We consider two-dimensional non-centrosymmetric superconductors, where the
order parameter is a mixture of s-wave and p-wave parts, in the presence of an
externally induced Zeeman splitting. We derive the conditions under which the
system is in a non-Abelian phase. By considering the non-degenerate zero-energy

A family $\F$ of sets is said to be intersecting if any two sets in $\F$ have
nonempty intersection. The celebrated Erd{\H o}s-Ko-Rado theorem determines the
size and structure of the largest intersecting family of $k$-sets on an $n$-set
$X$. An $(s,t)$-union intersecting family is a family of $k$-sets on an $n$-set

The show is about two sisters living together.

They try to support each other they make mistakes sometimes but they don't give up and continue. And the show is ... |
Acoustic cloaking for the suppression of backscattering inside ducts is
proposed in the audible range where plane waves are curved around the object
using the surface modes of the liner. It is numerically shown that a slowly

silence in which ... |

Judge Trader is going to order that Oki pay restitution however on release from prison, it is likely

Scant back-head coverage
Looking at the photos posted (making the mask look almost like a pseudo motorcycle helmet, I assumed this covered nearly the entire back of the head. It doesn't. Nearly the entirety of the back of the wearer's head is exposed. One another matter...the size. I don't know who has a head the size... |
Generic visual tracking is difficult due to many challenge factors (e.g.,
occlusion, blur, etc.). Each of these factors may cause serious problems for a
tracking algorithm, and when they work together can make things even more
complicated. Despite a great amount of efforts devoted to understanding the
behavior of tra... |
Distributed machine learning (ML) systems today use an unsophisticated threat
model: data sources must trust a central ML process. We propose a brokered

globally-shared model with provable privacy guarantees in an untrusted setting.
We realize this... |
Screening as part of a series of funny shorts at the Sydney Gay and Lesbian Mardi Gras film festival, this film was definitely a highlight. The script is great and the direction and acting was terrific. As another posting said, the actors' comedic timing really made this film. Lots of fun. |
Given an isoparametric function $f$ on the $n$-dimensional sphere, we
consider the space of functions $w\circ f$ to reduce the Yamabe equation on the
round sphere into a singular ODE on $w$ in the interval $[0,\pi]$, of the form
$w" + (h(r)/\sin r)w'+\lambda(\vert w\vert^{4/n-2}w - w)=0$, where $h$ is a
monotone func... |
The paper is mainly devoted to the irreducibility of the polynomial
representation of the double affine Hecke algebra for an arbitrary reduced root

non-semisimple variant is the main tool. We introduce Macdonald's
non-semisimple polynomials ... |
Seems Old - Birds Won't Eat
After buying the 10 pound bag time and time again, I bought the 20 pound bag and it does not seem fresh. The birds aren't eating it, it looks off, not dark black like normal and the bag doesn't have the nice easy open, easy close seal. I hope they get the 10 pound bags back. |
New observations of GD 99 are analysed. The unusual pulsation behaviour,
showing both long and short periods, has been confirmed. All the available
periods show a grouping of short and long period modes with roughly regular
spacing. If we interpret the groups separately, a binary nature can be a
possible explanation ... |
Are geometrical summaries of the CMB and LSS sufficient for estimating

A doubly CKM-suppressed amplitude in $B^0\to J/\psi K_S$ leads to corrections
in CP asymmetries $S = \sin 2\beta, C=0$, which may be enhanced by
long-distance rescattering. It has been suggested that this enhancement may
lead to several percent corrections. We calculate an upper bound of order
$10^{-3}$ on rescatteri... |

We report on a scheme for the creation of time-bin entangled states out of

We prove that second-order hyperbolic Monge-Ampere equations for one function

Zero-shot text classification (0Shot-TC) is a challenging NLU problem to

Deep Learning is a state-of-the-art technique to make inference on extensive

The ground-state Hartree-Fock (HF) wavefunction of the Hooke's atom is not

It is hard to stabilize the p-wave superfluid state of cold atomic gas in

In this work, we review two methods used to approach singular Hamiltonians in
