We use the recent theory of spectral submanifolds (SSMs) for model reduction of nonlinear mechanical systems subject to parametric excitations. Specifically, we develop expressions for higher-order nonautonomous terms in the parameterizatio...
Computational demonstrations of density wave of Cooper pairs and paired-electron liquid in the quarter-filled band-A brief review [0.03%]

There has been strong interest recently in the so-called Cooper pair density wave, subsequent to the proposition that such a state occurs in the hole-doped cuprate superconductors. As of now, there is no convincing demonstration of such a s...

Phase space reconstruction (PSR) methods allow for the analysis of low-dimensional data with methods from dynamical systems theory, but their application to prediction models, such as those from machine learning (ML), is limited. Therefore,...
Time-series-analysis-based detection of critical transitions in real-world non-autonomous systems [0.03%]
基于时间序列分析的现实世界非自治系统临界跃迁检测方法研究

Klaus Lehnertz
Real-world non-autonomous systems are open, out-of-equilibrium systems that evolve in and are driven by temporally varying environments. Such systems can show multiple timescale and transient dynamics together with transitions to very diffe...
Emergence of cooperation under punishment: A reinforcement learning perspective [0.03%]
惩罚下的合作行为：增強式学习的视角
Chenyang Zhao,Guozhong Zheng,Chun Zhang et al.
Chenyang Zhao et al.
Punishment is a common tactic to sustain cooperation and has been extensively studied for a long time. While most of previous game-theoretic work adopt the imitation learning framework where players imitate the strategies of those who are b...

In this paper, we study the dynamics of synchronous Boolean networks and extend previously obtained results for binary Boolean networks to networks with state variables in a general Boolean algebra of 2p elements, with p>1. The method to do...

In this paper, we investigate the time evolution of the rank correlation coefficients of the prestige indicators of the journals (such as Scimago Journal Rank) over 21 years, for 9856 journals in various disciplines. The observed dependenci...

We explore large populations of phase oscillators interacting via random coupling functions. Two types of coupling terms, the Kuramoto-Daido coupling and the Winfree coupling, are considered. Under the assumption of statistical independence...
Exploring the seasonality and optimal control strategy of HIV/AIDS epidemic in China: The impact of seasonal testing [0.03%]
中国HIV/AIDS流行季节性及其最优控制策略的探究：常规自愿咨询检测项目的影响分析
Kai Zhang,Ling Xue,Xuezhi Li et al.
Kai Zhang et al.
In this work, we investigate how the seasonal variation in the number of individuals who are tested for an HIV antibody in outpatient clinics affects the HIV transmission patterns in China, which has not been well studied. Based on the char...
Sigmoid function model of parallel-connected DC-DC converters and analysis of their dynamic characteristics [0.03%]
并联直流变换器的 sigmoid 函数模型及其动态特性分析
Jia Gu,Yimin Lu,Xianfeng Huang et al.
Jia Gu et al.
Because of the manufacturing variations of circuit elements and the effects of parasitic parameters, the switching elements of parallel-connected modules cannot be synchronously switched. Consequently, the characteristics of these converter...
