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.

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

New Phytologist, EarlyView.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

How I Met Your Market: CEO'S Professional Experience and Reverse Innovation in Indian Pharmaceutical Firms

R&D Management, EarlyView.
ABSTRACT Reverse innovation refers to an innovation first developed or adopted in an emerging economy before being further developed and/or adopted in advanced ones. Despite the growing research on reverse innovation over the past decade, its firm‐level antecedents remain relatively unexplored.

Persistent and Emerging High‐Risk Clusters of Leprosy Detection in Brazil: A Nationwide Spatiotemporal Analysis, 2001–2023

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background Brazil accounts for a substantial share of the global leprosy burden, with persistent high‐risk areas and marked spatial inequalities in case detection. Identifying spatiotemporal clusters of transmission is crucial for targeting surveillance and control efforts.

Spatiotemporal Patterns and Socioeconomic Determinants of Pulmonary Tuberculosis in Piauí, Northeast Brazil, 2001–2024

Tropical Medicine &International Health, EarlyView.
ABSTRACT Background Pulmonary tuberculosis (PTB) remains a major public health problem, strongly associated with social and territorial inequalities. This study aimed to analyse temporal trends, spatiotemporal transmission patterns and socioeconomic determinants of PTB in the state of Piauí, Northeast Brazil, from 2001 to 2024.
