Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yang Zhang, Karteekeya Sastry, Iyla Rossi, Joshua Olick-Gibson, Jonathan J. Russin | Summary: Noninvasive imaging deep into the adult brain at submillimeter and millisecond scales remains a challenge in medical imaging. Here, we report a helmet based ultrasound brain imager built from a customized helmet, a […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Yiding Sun, Jiaxin Mao, Wei Xue, Danqing Xu | Summary: Large language models (LLMs) have demonstrated remarkable capabilities across various professional domains, with their performance typically evaluated through standardized benchmarks. However, the development of financial RAG benchmarks has been constrained by data confidentiality issues and […]

Wijethunga, Theresa Connors Stewart, Dennis J. Selkoe, Matthew P. Frosh, Derek H. Oakley, Bradley T. Hyman, August Yue Huang and Michael Miller | Summary: Tau deposition […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiaochen Wang, Zongyu Wu, Yuan Zhong, Xiang Zhang, Suhang Wang | Summary: Graph retrieval-augmented generation (GRAG) places high demands on graph-specific retrievers. However, existing retrievers often rely on language models pretrained on plain text, limiting their effectiveness due to domain misalignment and structure ignorance. To address these […]
Kavli Affiliate: James J. Bock | First 5 Authors: Brendan P. Crill, Yoonsoo P. Bach, Sean A. Bryan, Jean Choppin de Janvry, Ari J. Cukierman | Summary: We describe the SPHEREx Sky Simulator, a software tool designed to model science data for NASA’s SPHEREx mission that will carry out a series of all-sky spectrophotometric surveys […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Shuyao Xu, Cheng Peng, Jiangxuan Long, Weidi Xu, Wei Chu | Summary: Recent advances in model distillation demonstrate that data from advanced reasoning models (e.g., DeepSeek-R1, OpenAI’s o1) can effectively transfer complex reasoning abilities to smaller, efficient student models. However, standard practices employ rejection sampling, discarding incorrect […]
Kavli Affiliate: Jia Liu | First 5 Authors: Yang Bai, Ting-Kuo Chen, Jia Liu, Xiaolin Ma, | Summary: We present a complete Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three light-flavor quark framework. This formulation incorporates both the standard chiral Lagrangian and the full Wess-Zumino-Witten (WZW) term. By including instanton effects […]

Kavli Affiliate: Jia Liu | First 5 Authors: Junzhuo Li, Bo Wang, Xiuze Zhou, Peijie Jiang, Jia Liu | Summary: The interpretability of Mixture-of-Experts (MoE) models, especially those with heterogeneous designs, remains underexplored. Existing attribution methods for dense models fail to capture dynamic routing-expert interactions in sparse MoE architectures. To address this issue, we propose […]
