Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
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.

Choosing to Study Abroad, Work Abroad, or Stay Home: Do Socioeconomic Status, International Posture, and Language Proficiency Make a Difference?

The Modern Language Journal, EarlyView.
ABSTRACT Embracing “the political economy turn,” applied linguistics has increasingly examined socioeconomic class as a central construct in language learning. Prior research highlights links between socioeconomic status (SES) and learning outcomes, often contributing to divides such as the English Divide in South Korea.

Provenance and environment jointly shape early regeneration in fir and beech: evidence from distributed participatory trials across Europe

New Phytologist, EarlyView.
Location of fir (Abies) and beech (Fagus) seed provenances and the experimental field sites called micro‐gardens. Summary Forest regeneration is shaped by strong demographic filters during germination and early establishment, yet the relative contributions of seed provenance and environment remain poorly understood under natural conditions. We combined

Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.
