We study the occupation time statistics for non-Markovian random walkers based on the formalism of the generalized master equation for the continuous-time random walk. We also explore the case when the random walker additionally undergoes a...

We apply evolutionary reinforcement learning to a simulation model to identify efficient time-dependent erasure protocols for a physical realization of a 1-bit memory using an underdamped mechanical cantilever. We show that these protocols,...
Transient asymmetry during elastic snap-through: The interplay between imperfections and oscillations [0.03%]
弹性跳跃过程中瞬时不对称性：缺陷与振荡的相互作用

A symmetrically buckled arch whose boundaries are clamped at an angle has two stable equilibria: an inverted and a natural state. When the distance between the clamps is increased (i.e., the confinement is decreased), the system snaps from ...
Generalized correlations in disordered dynamical systems: Insights from the many-species Lotka-Volterra model [0.03%]
无序动力系统中的广义相关性：许多物种Lotka-Volterra模型的见解

In the study of disordered systems, one often chooses a matrix of independent identically distributed interaction coefficients to represent the quenched random couplings between components, perhaps with some symmetry constraint or correlati...
Driving of an open quantum system at finite temperature across first- and second-order quantum phase transitions [0.03%]
有限温度下穿越一阶和二阶量子相变的开放量子系统动力学

An open fully connected system of qubits at nonzero temperature is driven within a finite time interval along various paths in the space of its control parameters. The driving leads across finite-size precursors of first- and second-order q...
Hyperbolic embedding of brain networks detects regions disrupted by neurodegeneration in Alzheimer's disease [0.03%]

Graph-theoretical methods have proven valuable for investigating alterations in both anatomical and functional brain connectivity networks during Alzheimer's disease (AD). Recent studies suggest that representing brain networks in a suitabl...
Microbial populations hardly ever grow logistically and never sublinearly [0.03%]
微生物种群几乎从不呈逻辑斯谛方式增长也从不以次线性的方式增长

We investigate the growth dynamics of microbial populations, challenging the conventional logistic model. By analyzing empirical data from various biomes, we demonstrate that microbial growth is better described by a generalized logistic mo...
Migration feedback induces emergent ecotypes and abrupt transitions in evolving populations [0.03%]

We explore the connection between migration patterns and emergent behaviors of evolving populations in spatially heterogeneous environments. Despite extensive studies in systems of ecological and medical importance, a unifying framework tha...
Unveiling the hidden weak universality of the Ziff-Gulari-Barshad model [0.03%]

In this work, we revisited the Ziff-Gullari-Barshad (ZGB) model in order to investigate its critical behavior when carbon monoxide (CO) molecules are allowed to desorb from the catalytic surface. As shown by several authors, when this kind ...

We study the first-passage time (FPT) problem for widespread recurrent processes in confined though large systems and present a comprehensive framework for characterizing the FPT distribution over many timescales. We find that the FPT stati...
