    Machine learning configuration-dependent friction tensors in Langevin heatbaths by Matthias Sachs, Wojciech G Stark, Reinhard J Maurer, Christoph Ortner

    Published 2025-01-01
    “…Dynamics of coarse-grained particle systems derived via the Mori–Zwanzig projection formalism commonly take the form of a (generalized) Langevin equation with configuration-dependent friction tensor and diffusion coefficient matrix. In this article, we introduce a class of equivariant representations of tensor-valued functions based on the Atomic Cluster Expansion framework that allows for efficient learning of such configuration-dependent friction tensors from data. …”

    How does agricultural insurance influence grain production scale? An income-mediated perspective by Dainan Hou, Xin Wang, Xin Wang

    Published 2025-01-01
    “…This study applies the von Neumann-Morgenstern expected utility model, coupled with theories on economies of scale, technology diffusion, and rational choice, to examine the theoretical links between agricultural insurance, farmers’ income, and grain production scale.ResultsUsing panel data from 27 Chinese provinces between 2011 and 2021, analyzed through fixed-effects and mediation models, the study finds that agricultural insurance positively, albeit moderately, impacts the scale of grain production, with farmers’ income serving as a partial mediating factor.DiscussionBased on these findings, we recommend expanding agricultural insurance coverage, developing a multi-level insurance framework, and enhancing insurance protection levels to bolster sustainable agricultural development and food security in China.…”
