In fluids under temperature gradients, long-range correlations (LRCs) emerge generically, leading to enhanced density fluctuations. This phenomenon, characterized by the q^{-4} divergence in the static structure factor (where q is the waven...
Pine Island Glacier Ice Shelf (West Antarctica) is more sensitive to climate conditions than to rheological parameters on multidecadal timescales [0.03%]

Quantum reservoir computing is an emergent field in which quantum dynamical systems are exploited for temporal information processing. Previous work found a feature that makes a quantum reservoir valuable: contractive dynamics of the quantu...

Using the Metropolis algorithm, we simulate the relaxation process of the three-dimensional kinetic Ising model. Starting from a random initial configuration, we first present the average equilibration time across the entire phase boundary....

Spatial metapopulation models are fundamental to theoretical ecology, enabling us to study how landscape structure influences global species dynamics. Traditional models, including recent generalizations, often rely on the deterministic lim...
Oscillatory sound pulses, with or without axial angular momentum, localized in space and time [0.03%]

Results are given for the exact energy and momentum of a family of oscillatory pulses. The pulses are characterized by a length a and a dominant wave number K. Pulses with angular momentum about the direction of propagation are also discuss...
Amplification of Laguerre-Gaussian laser pulses in plasma by copropagating Gaussian pulses [0.03%]

Two numerical methods are proposed to detect and analyze coupling in time series from deterministic nonlinear systems. The first identifies the presence of coupling or interdependence, while the second determines the directionality of coupl...
Mass correction approach to reduce the droplet spontaneous shrinkage in free-energy-based lattice Boltzmann method [0.03%]
基于自由能的格子玻尔兹曼方法中减少液滴自发收缩的质心校正方法

Cheng Peng et al.
The free-energy-based lattice Boltzmann method has emerged as a reliable tool for simulating multiphase flows, but its application to small droplet interactions with surrounding flows is hindered by the issue of spontaneous droplet shrinkag...
Differential migration in a finite-island model and the evolution of cooperation [0.03%]

In this paper, we investigate the evolution of cooperation in a haploid population subdivided into d demes, each composed of N≥2 individuals interacting according to a Prisoner's Dilemma. Using a discrete-time Moran process with migration ...
