Kinetic simulations and theory demonstrate that whistler waves can excite
oblique, short-wavelength fluctuations through secondary drift instabilities if
a population of sufficiently cold plasma is present. The excited modes lead to
heating of the cold populations and damping of the primary whistler waves. The

Knowledge graph embedding has been an active research topic for knowledge
base completion (KGC), with progressive improvement from the initial TransE,
TransH, RotatE et al to the current state-of-the-art QuatE. However, QuatE

relation, only usin... |
One of the features of the unconventional $s_\pm$ state in iron-based
superconductors is possibility to transform to the $s_{++}$ state with the
increase of the nonmagnetic disorder. Detection of such a transition would

dependence of the London m... |

context. Amo... |
Deep Reinforcement Learning (RL) techniques can benefit greatly from

power spectrum ... |

Determining whether two particle systems are similar is a common problem in
particle simulations. When the comparison should be invariant under
permutations, orthogonal transformations, and translations of the systems,
special techniques are needed. We present an algorithm that can test particle

As observations of the Hubble parameter from both early and late sources have
improved, the tension between these has increased to be well above the
5$\sigma$ threshold. Given this, the need for an explanation of such a tension
has grown. In this paper, we explore a set of 7 assumptions, and show that, in
order to al... |
Humans express feelings or emotions via different channels. Take language as

these generat... |
Multiexcitons in monolayer WSe2 exhibit a suite of optoelectronic phenomena

attributed to the multiexc... |
The recently discovered non-Hermitian skin effect (NHSE) manifests the
breakdown of current classification of topological phases in

We use exponent pairs to establish the existence of many $x^a$-smooth numbers
in short intervals $[x-x^b,x]$, when $a>1/2$. In particular, $b=1-a-a(1-a)^3$

A graph $G$ is called a $2K_2$-free graph if it does not contain $2K_2$ as an
induced subgraph. In 2014, Broersma, Patel and Pyatkin showed that every

Shan improved this result by showing that 3-tough is sufficient instead of
25-tough. In... |

(\textit{SISNet}), which ... |
We prove that a system of equations introduced by Demailly (to attack a

potential, w... |
For a complex projective manifold, Walker has defined a regular homomorphism
lifting Griffiths' Abel-Jacobi map on algebraically trivial cycle classes to a

For every $p\in(0,\infty)$, a new metric invariant called umbel $p$-convexity
is introduced. The asymptotic notion of umbel convexity captures the geometry
of countably branching trees, much in the same way as Markov convexity, the

trees. Umbe... |
Distance metrics and their nonlinear variant play a crucial role in machine

to teach) ... |
The origin and composition of ultra-high energy cosmic rays (UHECRs) remain a
mystery. The common lore is that UHECRs are deflected from their primary

an extragalactic contribution to the deflection of UHECRs that does not depend
on the st... |
To understand the true nature of black holes, fundamental theoretical
developments should be linked all the way to observational features of black

corresponds to... |
Self-Admitted Technical Debt (SATD) is a metaphorical concept to describe the

problem th... |
Machine-learning force fields (MLFF) should be accurate, computationally and
