We present the results of Monte-Carlo studies of the non-equilibrium
properties of ferromagnetic Heisenberg films. Aging effects were observed in
non-equilibrium critical behavior. The calculations were carried out for both
high-temperature and low-temperature initial states. The characteristic
correlation time, which ... | http://arxiv.org/abs/2302.04746v1 |
There is no known reason that dark matter interactions with the Standard
Model should couple to neutrons and protons in the same way. This isospin
violation can have large consequences, modifying the sensitivity of existing
and future direct detection experimental constraints by orders of magnitude.

Brain tumors, particularly glioblastoma, continue to challenge medical
diagnostics and treatments globally. This paper explores the application of
deep learning to multi-modality magnetic resonance imaging (MRI) data for
enhanced brain tumor segmentation precision in the Sub-Saharan Africa patient
population. We introd... | http://arxiv.org/abs/2308.07214v1 |
We discuss the growth of the Lebesgue constants for polynomial interpolation
at Fekete points for fixed degree (one) and varying dimension, and underlying
set $K\subset \R^d$ a simplex, ball or cube. | http://arxiv.org/abs/2305.01699v1 |
The even light QCD axion called the $Z_{\mathcal N}$ axion can both solve the
strong CP problem and account for the dark matter (DM). We point out that the
single and double level crossings can naturally take place in the mass mixing
between the $Z_{\mathcal N}$ axion and axionlike particle (ALP). The first
level cross... | http://arxiv.org/abs/2310.02126v2 |
This paper deals with U-statistics of Poisson processes and multiple
Wiener-It\^o integrals on the Poisson space. Via sharp bounds on the cumulants
for both classes of random variables, moderate deviation principles,
concentration inequalities and normal approximation bounds with Cram\'er
correction are derived. It is ... | http://arxiv.org/abs/2304.00876v2 |
We simulate the evolution of the helicity of relic neutrinos as they
propagate to Earth through a realistic model of the Galactic magnetic field,
improving upon the rough estimates in the literature. For magnetic moments
consistent with experimental bounds and several orders of magnitude smaller, we
confirm that the he... | http://arxiv.org/abs/2303.15562v2 |
Interferometers (e.g. ALMA and NOEMA) allow us to obtain the detailed
brightness distribution of astronomical sources in 3 dimensions (R.A., Dec.,
frequency). However, the spatial correlation of the noise makes it difficult to
evaluate the statistical uncertainty of the measured quantities and the
statistical significa... | http://arxiv.org/abs/2301.03579v2 |
Bilingual Lexicon Induction (BLI) is a core task in multilingual NLP that
still, to a large extent, relies on calculating cross-lingual word
representations. Inspired by the global paradigm shift in NLP towards Large
Language Models (LLMs), we examine the potential of the latest generation of
LLMs for the development o... | http://arxiv.org/abs/2310.13995v2 |
Through experimentation, we have discovered that with the changing of driving
conditions, the Faraday waves undergo two abrupt transitions in spatiotemporal
order: onset and instability. The driving amplitudes and frequencies
corresponding to these two transition points exhibit power-law relationships.
The power-law ex... | http://arxiv.org/abs/2305.06690v2 |
In this paper, we study a fundamental problem in submodular optimization,
which is called sequential submodular maximization. Specifically, we aim to
select and rank a group of $k$ items from a ground set $V$ such that the
weighted summation of $k$ (possibly non-monotone) submodular functions $f_1,
\cdots ,f_k: 2^V \ri... | http://arxiv.org/abs/2308.08641v2 |
In this paper, the fractal calculus of fractal sets and fractal curves are
compared. The analogues of the Riemann-Liouville and the Caputo integrals and
derivatives are defined for the fractal curves which are non-local derivatives.
The analogous for the fractional Laplace concepts are defined to solve fractal
non-loca... | http://arxiv.org/abs/2302.12642v1 |
The theoretical prediction that magnetic reconnection spontaneously drives
turbulence has been supported by magnetohydrodynamic (MHD) and kinetic
simulations. While reconnection with externally driven turbulence is accepted
as an effective mechanism for particle acceleration, the acceleration during
the reconnection wi... | http://arxiv.org/abs/2308.07572v1 |
