Attribute Structuring Improves LLM-Based Evaluation of Clinical Text Summaries [PDF]

open access: yesarXiv
Summarizing clinical text is crucial in health decision-support and clinical research. Large language models (LLMs) have shown the potential to generate accurate clinical text summaries, but still struggle with issues regarding grounding and evaluation, especially in safety-critical domains such as health.

Enhancing Amplified Spontaneous Emission in Perovskite Thin Films by Thickness Regulation: Insights into Carrier Distribution and Optical Confinement

open access: yesAdvanced Optical Materials, EarlyView.
This study reveals the critical influence of film thickness and excitation wavelength on the ASE threshold in metal halide perovskites. By optimizing these factors, the ASE threshold is significantly reduced, providing key insights into optical confinement and carrier distribution for advancing electrically pumped perovskite lasers.
