Julian Sierra-Velez et al.
We present a machine learning approach based on symbolic regression to derive, from either numerically generated or experimentally measured spectral data, closed-form expressions that model the optical properties of biological materials. To...
Stabilization of macroscopic dynamics by fine-grained disorder in many-species ecosystems [0.03%]
细粒度无序在多物种生态系统中的宏观动力学稳定作用

Models for complex, heterogeneous systems such as ecological communities vary in the level of organization they describe. When the dynamics at the species level is unknown, one typically resorts to heuristic "macroscopic" models that captur...

We study a system of globally coupled FitzHugh-Nagumo oscillators with pairwise and second-order interactions, showing that the presence of higher-order interactions substantially affects the character of the transition between synchronous ...
Intensity landscapes in elliptic and oval billiards with a circular absorbing region [0.03%]

Billiard models of single particles moving freely in two-dimensional regions enclosed by hard walls have long provided ideal toy models for the investigation of dynamical systems and chaos. Recently, billiards with (semi)permeable walls and...

Lattice-gas algorithms (LGA) are a class of algorithms including, in chronological order, binary lattice-gas cellular automata, integer lattice-gas algorithms (ILGA), and lattice Boltzmann method (LBM). They are largely used for simulating ...
Cooperation, satisfaction, and decision uncertainty in social games on complex networks with aspiration-driven players [0.03%]
基于期望的驱动下合作、满意度和决策不确定性在复杂网络上的社会游戏中的研究
M Aguilar-Janita,N Khalil,I Leyva et al.
M Aguilar-Janita et al.
A network model based on players' aspirations is proposed and analyzed theoretically and numerically within the framework of evolutionary game theory. In this model, players decide whether to cooperate or defect by comparing their payoffs f...
Electron cumulative distribution function in a magnetron sputtering discharge [0.03%]

This study investigates electron kinetics in a direct current magnetron sputtering discharge, advocating for the use of the cumulative distribution function (CDF) as a superior alternative to conventional probability distribution functions ...
Self-organization and emergence of memory in a cyclically driven elastoplastic model of an amorphous solid [0.03%]
周期驱动下的弹性塑性非晶固体内记忆的自组织和涌现现象研究

Dheeraj Kumar et al.
The mechanical behavior of disordered materials, such as dense suspensions, glasses, and granular materials, depends on their thermal and mechanical history. Under periodic driving, these materials can evolve into states that encode a memor...
Integrable matrix probabilistic diffusions and the matrix stochastic heat equation [0.03%]
可积矩阵概率扩散及矩阵随机热方程
Alexandre Krajenbrink,Pierre Le Doussal
Alexandre Krajenbrink
We introduce a matrix version of the stochastic heat equation, the MSHE, and obtain its explicit invariant measure in spatial dimension D=1. We show that it is classically integrable in the weak-noise regime in terms of the matrix extension...
Electric conductivity in open quantum two-dimensional nonmagnetic systems: The role of the nondiagonal dissipative kernels and the non-Markovian effect [0.03%]

In two-dimensional nonmagnetic systems, the influence of strong correlations between random forces in the equations of motion for the components of the charge carrier momentum on electric conductivity is studied within the framework of the ...
