Bursty Star Formation in Dwarfs is Sensitive to Numerical Choices in Supernova Feedback Models

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Eric Zhang, Laura V. Sales, Federico Marinacci, Paul Torrey, Mark Vogelsberger | Summary: Simulations of galaxy formation are mostly unable to resolve the energy-conserving phase of individual supernova events, having to resort to subgrid models to distribute the energy and momentum resulting from stellar feedback. However, the […]

In-situ aligned all-polarization-maintaining Er-doped fiber laser mode-locked by a nonlinear amplifying loop mirror

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Kangrui Chang, Haobin Zheng, Yongzhuang Zhou, Yong Shen | Summary: Despite the wide applications for high-repetition-rate mode-locked fiber lasers, challenges persist in shortening the cavity length and coupling the fiber collimators for most existing techniques. Here, we introduce a novel collimator alignment method and demonstrate […]

BLEnD: A Benchmark for LLMs on Everyday Knowledge in Diverse Cultures and Languages

Kavli Affiliate: Yi Zhou | First 5 Authors: Junho Myung, Nayeon Lee, Yi Zhou, Jiho Jin, Rifki Afina Putri | Summary: Large language models (LLMs) often lack culture-specific knowledge of daily life, especially across diverse regions and non-English languages. Existing benchmarks for evaluating LLMs’ cultural sensitivities are limited to a single language or collected from […]

The graphene squeeze-film microphone

Kavli Affiliate: P. G. Steeneken | First 5 Authors: M. P. Abrahams, J. Martinez, P. G. Steeneken, G. J. Verbiest, | Summary: Most microphones operate by detecting the sound-pressure induced motion of a membrane. In contrast, here we introduce a microphone that operates by monitoring the sound-pressure-induced modulation of the compressibility of air. By driving […]
