Memory-dependent bistability and criticality in a stochastic Wilson-Cowan model [0.03%]
记忆依赖的双稳态和临界性在随机Wilson–Cowan模型中的研究

We introduce a new version of the stochastic Wilson-Cowan model to account for the memory created by multistep state transition processes. To solve this complex non-Markov model, we introduce effective transition rates, which explicitly dec...
Quasi-two-dimensional soliton in a self-repulsive spin-orbit-coupled dipolar binary condensate [0.03%]

We study the formation of solitons in a uniform quasi-two-dimensional (quasi-2D) spin-orbit (SO) coupled self-repulsive binary dipolar and nondipolar Bose-Einstein condensate (BEC) using the mean-field Gross-Pitaevskii equation. For a weak ...
Macroscopic dynamics of quadratic integrate-and-fire neurons subject to correlated noise [0.03%]

The presence of correlated noise, arising from a mixture of independent fluctuations and a common noisy input shared across the neural population, is a ubiquitous feature of neural circuits, yet its impact on collective network dynamics rem...

In many biological processes, the size of a population changes stochastically with time, and recent work in the context of cancer and bacterial growth have focused on the situation when the mean population size grows exponentially. Here, mo...
Modeling of contact angle hysteresis for rigid mobile particles: A phase-field lattice Boltzmann approach [0.03%]
刚性移动颗粒的接触角迟滞建模：一种相场格子boltzmann方法
Malyadeep Bhattacharya,Jovina Vaswani,Sachin S Velankar et al.
Malyadeep Bhattacharya et al.
We introduce a scheme for contact angle hysteresis in the presence of moving curved solid boundaries for a class of two-phase fluid models, where the interface between fluid phases is diffuse, while the ones involving solid phases are sharp...
Clogging-flowing transition of granular media in a two-dimensional vertical pipe [0.03%]
二维垂直管道中颗粒介质的堵塞-流动相变
Y Zhou,M Li,Y Guan et al.
Y Zhou et al.
We experimentally and numerically investigate the clogging behavior of granular materials in a two-dimensional vertical pipe. The nonmonotonicity of the clogging probability found in a cylindrical vertical pipe [López et al., Phys. Rev. E ...
Rayleigh-Taylor instability in size-bidisperse isodense granular flow down an incline [0.03%]
斜坡上双粒径等密度颗粒流的瑞利-泰勒不稳定性

Umberto D&#x;Ortona
Size-bidisperse granular material flowing down a rough incline, or chute, may develop a Rayleigh-Taylor instability even when the two particle species have the same density. Unlike fluid instability, which occurs under quiescent conditions,...

Vector-borne diseases arise from the coupled dynamics of human mobility and mosquito ecology, producing outbreaks shaped by both spatial distributions and temporal patterns of movement. Here we develop a coarse-grained hub-leaf reduction th...
Assessment of mixing in rotating microfluidic channels: A variational calculus approach [0.03%]
变分计算在旋转微流控通道中的混合评估

We present a theoretical investigation of the mixing dynamics of two constituent fluids within a soft rotating microfluidic channel. We solve a coupled system of transport equations, governing the mixing dynamics in this endeavor, with the ...

We develop a rotational gauge invariance for classical many-body ensembles with orientational degrees of freedom and, from it, derive a hierarchy of exact, closure-free Ward identities on the orientation sphere S^{2} and on SO(3). A master ...
