Reinforcement Learning for Jump‐Diffusions, With Financial Applications
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

A deep learning‐enabled toolkit for the 3D segmentation of ventricular cardiomyocytes
Abstract figure legend 3D cardiomyocyte segmentation enables comprehensive analyses of myocardial microstructure in health and disease; however, it is technically demanding. We present an open‐source toolkit for this task, which reduces challenges associated with sample preparation, image restoration, segmentation and proofreading.

Lithium Isotopic Analysis of Spodumene by Secondary Ion Mass Spectrometry
ABSTRACT Rationale Lithium (Li) stable isotopes can provide insight into fluid–rock interaction and magmatic differentiation. Therefore, it is essential to develop an accurate and precise method to determine the Li isotope signature in spodumene.
