MedGR: Breaking the Data Barrier for Medical Reasoning via Generative Reward Learning

Weihai Zhi, Jiayan Guo, Shangyang Li

The application of Vision-Language Models (VLMs) in medicine is critically hampered by the scarcity of high-quality, expert-annotated data. Supervised Fine-Tuning (SFT) on existing…

near new Dirac points in graphene superlattice

Jianli Luan, Shangyang Li, Tianxing Ma +1

New Dirac points appear when periodic potentials are applied to graphene, and there are many interesting effects near these new Dirac points. Here we investigate the $\textit{Zitte…
