This study presents a specific symplectic map, derived from a Hamiltonian, as a model that exhibits time-reversal symmetry on a microscopic scale. Based on the analysis, any initial density function, defined almost everywhere, converges to ...
Detection of winding deformations in power transformers from inrush current characteristics using the Chen-Lee chaotic system and Gramian Angular Summation Field [0.03%]

A short-circuit fault in a transmission line unbalances the electromagnetic stress or ferromagnetic resonance, which deforms the internal windings of a power transformer. In addition, aged power transformers that have been operating for >25...
How more data can hurt: Instability and regularization in next-generation reservoir computing [0.03%]
更多的数据如何带来伤害：下一代水库计算中的不稳定性和正则化问题

It has been found recently that more data can, counter-intuitively, hurt the performance of deep neural networks. Here, we show that a more extreme version of the phenomenon occurs in data-driven models of dynamical systems. To elucidate th...

Resetting, as a protocol that restarts the evolution of a system, can significantly influence stochastic dynamics. One notable effect is the emergence of stationary states in unbounded potentials, where such states would otherwise be absent...
A universal route from avalanches in mean-field models with random fields to stochastic Poisson branching events [0.03%]
从含随机场平均场模型中的雪崩到随机泊松分支事件的普适途径

Avalanches in mean-field models can be mapped to memoryless branching processes defining a universality class. We present a reduced expression mapping a broad family of critical and subcritical avalanches in mean-field models at the thermod...
A three-dimensional memristor-based hyperchaotic map for pseudorandom number generation and multi-image encryption [0.03%]

The resistance state of a memristor can be influenced by external stimuli, and these variations can be converted into a pseudorandom sequence through appropriate circuitry and control mechanisms. By leveraging this property, a reliable and ...
Machine learning informed by micro- and mesoscopic statistical physics methods for community detection [0.03%]

Community detection plays a crucial role in understanding the structural organization of complex networks. Previous methods, particularly those from statistical physics, primarily focus on the analysis of mesoscopic network structures and o...
Liquid dynamics in a crowded environment: Bond percolation vs site percolation [0.03%]
液体在拥挤环境中的动力学：键渗流与位点渗流

The main problem studied is how the diffusion of liquid occurs in the presence of obstacles. In general, this question cannot be reduced to either bond or site percolation, because in real media, the diffusion problem is a complex combinati...

In cardiac tissue, the sinoatrial node (SAN) is responsible for initiating the periodic electrical pulses underlying heart beats. However, other heterogeneities (e.g., ischemic regions) can act as rogue pacemakers and produce oscillations i...
Comparative analysis of nonlocal interactions in a two-dimensional prey-predator model with Allee effect in predator growth, and Holling type II functional response [0.03%]
带Allee效应的捕食者增长和Holling II型功能反应的二维预捕食者模型中非局部相互作用的比较分析

This article presents a comprehensive investigation into a two-dimensional nonlocal spatiotemporal model, incorporating a generalist predator and addressing the Allee effect in predator growth. We study two types of nonlocality. First, by i...
