This article aims at clarifying the situation about astrophysical sources
that might be observed with haloscope experiments sensitive to gravitational
waves in the 1-10 GHz band. The GrAHal setup is taken as a benchmark. We follow
a very pe...

Recent photometric observations of massive stars have identified a
low-frequency power excess which appears as stochastic low-frequency
variability in light curve observations. We present the oscillation properties
of high resolution hydrod...
Stochastic evolution equations with Wick-analytic nonlinearities

Functional Analysis
We study nonlinear stochastic partial differential equations with
Wick-analytic type nonlinearities set in the framework of white noise analysis.
These equations include the stochastic Fisher--KPP equations, stochastic
Allen--Cahn, stochast...

Data Structures and Algorithms
We consider the problem of counting 4-cycles (C4) in an undirected graph
G of n vertices and m edges (in bipartite graphs, 4-cycles are also often
referred to as butterflies). There have been a number of previous
algorit...
Probing the CP nature of the top-Higgs Yukawa coupling in ttˉH
and tH events with H→bbˉ decays using the ATLAS detector at the
LHC

Physics
High Energy Physics - Experiment
The CP properties of the coupling between the Higgs boson and the top quark
are investigated with 139 fb−1 of proton-proton collision data recorded by
the ATLAS experiment at the LHC at a centre-of-mass energy of s=13
TeV. T...

In this work, we introduce a game-theoretic model that assesses the
cyber-security risk of cloud networks and informs security experts on the
optimal security strategies. Our approach combines game theory, combinatorial
optimization, and cy...

We use Boltzmann model to study the semi-classical dynamics of electrons in a
two-dimensional (2D) tilted Dirac material in which the tilt varies in space.
The spatial variation of the tilt parameter induces a non-trivial spacetime
geometry...

The primary objective of this paper is to generalize the results of
[arXiv:2111.03548] to the case of quasi-smooth Berkovich curves by establishing
a connection between the spectrum and the radii of convergence. To achieve
this, we investig...

Long-term temporal fusion is a crucial but often overlooked technique in
camera-based Bird's-Eye-View (BEV) 3D perception. Existing methods are mostly
in a parallel manner. While parallel fusion can benefit from long-term
information, it su...
