Eukaryotic centromeres contain the kinetochore, which connects chromosomes to the spindle allowing segregation. During meiosis, centromeres are suppressed for inter-homolog crossover, as recombination in these regions can cause...

This paper introduces and analyzes an original class of Krylov subspace methods that provide an efficient alternative to many well-known conjugate-gradient-like (CG-like) Krylov solvers for square nonsymmetric linear systems...

Plasma membrane tension regulates many key cellular processes. It is modulated by, and can modulate, membrane trafficking. However, the cellular pathway(s) involved in this interplay is poorly understood. Here we find that...

During the night of 01-02 September, 2009, seventeen distinct sprite events including 3 halos were observed above a storm in north-western Mediterranean Sea, with a video camera at Pic du Midi (42.93N; 0.14E; 2877 m). The...
Short-term diabetic hyperglycemia suppresses celiac ganglia neurotransmission, thereby impairing sympathetically mediated glucagon responses.
Short-term hyperglycemia suppresses superior cervical ganglia neurotransmission. If this ganglionic dysfunction also occurs in the islet sympathetic pathway, sympathetically mediated glucagon responses could be impaired. Our...

Quantum Zeno Effect in Open Quantum Systems
We prove the quantum Zeno effect in open quantum systems whose evolution,
governed by quantum dynamical semigroups, is repeatedly and frequently
interrupted by the action of a quantum operation. For the case of a...
An AI Using Construction Grammar to Understand Text
Denis Kiselev
Apr 01, 2021
This paper describes an AI that uses construction grammar (CG)—a means of knowledge representation for deep understanding of text. The proposed improvements aim at more versatility of the text form and meaning knowledge...

Feb 09, 2021
Neural networks enjoy widespread success in both research and industry and, with the advent of quantum technology, it is a crucial challenge to design quantum neural networks for fully quantum learning tasks. Here we propose a...
A Cloud-Edge Collaborative Gaming Framework Using AI-Powered Foveated Rendering and Super Resolution
Cloud gaming (CG) has gradually gained popularity. By leveling shared computing resources on the cloud, CG technology allows those without expensive hardware to enjoy AAA games using a low-end device. However, the bandwidth...

Apr 12, 2019
Leishmania donovani is the responsible agent for visceral leishmaniasis (VL) in the Indian subcontinent (ISC). The disease is lethal without treatment and causes 0.2 to 0.4 million cases each year. Recently, reports of VL in...
A method to challenge symmetries in data with self-supervised learning
Abstract Symmetries are key properties of physical models and of experimental designs, but any proposed symmetry may or may not be realized in nature. In this paper, we introduce a practical and...
Constrained invariant mass distributions in cascade decays. The shape of the "m(qll)-threshold" and similar distributions
CG Lester
Jan 12, 2010
Considering the cascade decay $D\to c C \to c b B \to c b a A$ in which
$D,C,B,A$ are massive particles and $c,b,a$ are massless particles, we
determine for the first time the shape of the distribution of the invariant
mass of...
Many-Body Coarse-Grained Interactions Using Gaussian Approximation Potentials.
We introduce a computational framework that is able to describe general many-body coarse-grained (CG) interactions of molecules and use it to model the free energy surface of molecular liquids as a cluster expansion in terms of...

Measuring the Higgs boson mass in dileptonic W-boson decays at hadron colliders
It is expected that hadron collider measurements of the Higgs boson mass
using the decay h -> W^+W^-, followed by the leptonic decay of each W-boson,
will be performed by fitting the shape of a distribution which is sensitive...
Weighing wimps with kinks at colliders
We consider the application of endpoint techniques to the problem of mass
determination for new particles produced at a hadron collider, where these
particles decay to an invisible particle of unknown mass and one or...
Standard model and supersymmetric flavor puzzles at the CERN large hadron collider
Can the Large Hadron Collider explain the masses and mixings of the known
fermions? A promising possibility is that these masses and mixings are
determined by flavor symmetries that also govern new particles that will appear
at...
A randomised controlled trial of the effectiveness of a breastfeeding training DVD on improving breastfeeding knowledge and confidence among healthcare professionals in China.
Background: Despite almost all babies being breastfed initially, the rates of exclusive breastfeeding rate at six months is only 30% in China. Improving professionals' knowledge and practical skill is a key government strategy...
