The addition of a small fraction of flexible fibers to a granular medium is known to enhance the bulk mechanical strength of the material. However, their effect on the free-surface flow of grains remains largely unexplored. To address this ...

We present a realizable entropic lattice Boltzmann method (RELBM) for scalar transport at high Péclet (Pe) number. The method combines an ADE-tailored entropic relaxation with a nonorthogonality correction to ghost-mode damping and a stric...
Mutual linearity in and out of stationarity for Markov jump processes: A trajectory-based approach [0.03%]

The ability to quantify the similarity of stochastic processes is important in a wide range of areas including communications, simulation, and operational research. Such processes are commonly modeled as Markov Chains and so a natural way t...
Alternating pattern formation in oscillatory media with spatially uniform and nonuniform global feedback [0.03%]

Alternating (temporally period-2) stripes, clusters, and labyrinths have been observed in chemical and biochemical reactions, in Min-protein dynamics in E. coli and in vitro systems, and in calcium alternans in cardiac myocytes. However, th...

We investigate equilibration dynamics in a lattice-gas model with spatially restricted coupling to a particle reservoir. Using kinetic Monte Carlo simulations, we isolate the role of reservoir-access geometry by comparing spatially uniform ...
Computer simulations of the Stark effect in the helium-β complex of krypton in inertial confinement fusion conditions [0.03%]

There is an ongoing interest in using spectroscopy in inertial confinement fusion (ICF) experiments, where dopants such as krypton can provide vital information about the temperature and density of the imploding plasma. While the most advan...
Intrinsic density of states and the origin of Gamma volume distributions in jammed granular matter [0.03%]
堆积颗粒材料的内在状态密度和Gamma体积分布的起源

Athermal systems such as granular materials exhibit reproducible volume fluctuations despite the absence of thermal equilibration, yet a quantitative statistical-mechanical description remains incomplete. Within the Edwards ensemble, volume...
Unified speed limits in classical and quantum dynamics via temporal Fisher information [0.03%]
经典和量子动力学中的统一速度极限通过时间费舍尔信息得出
Tomohiro Nishiyama,Yoshihiko Hasegawa
Tomohiro Nishiyama
The importance of Fisher information is increasing in nonequilibrium thermodynamics, as it has played a fundamental role in trade-off relations such as thermodynamic uncertainty relations and speed limits. In this work, we investigate tempo...
Dynamic effects of electric fields in a hybrid-coupled thermosensitive neuronal network [0.03%]
