PR-OPD: Privileged Representation On-policy Self-Distillation for Agentic Reinforcement Learning

Language-model agents are usually trained by reinforcement learning from one reward per episode, and privileged self-distillation enriches it by letting the same policy, given a skill, teach its skill-free self through token probabilities. However, we identify two phenomena that question this channel. Invisible Advanta...

Spatiotemporally programmed core-shell multilayer hydrogel spheres dressing for scarless infected wound healing.

Bacterially infected wounds often exhibit dysregulated inflammatory responses and ineffective pathogen clearance, leading to a dysregulated healing cascade and pathological scarring. Here, we present a spatiotemporally programmed core-shell hydrogel sphere system engineered via a molecular-weight-gradient hyaluronic ac...

PaSTel: Anchoring Histology in Spatial Transcriptomics via Multi-Scale Hierarchical Bio-Prior Contrastive Pretraining

PaSTel is introduced, a hierarchical multimodal pretraining framework that integrates biological priors at three levels that consistently outperforms existing vision and vision-omics encoders, demonstrating that incorporating multiscale biological priors yields more informative and transferable representations for spat...
