Kavli Affiliate: Zhuo Li | First 5 Authors: Xuying Li, Zhuo Li, Yuji Kosuga, Victor Bian, | Summary: Aligning large language models (LLMs) with human values and safety constraints is challenging, especially when objectives like helpfulness, truthfulness, and avoidance of harm conflict. Reinforcement Learning from Human Feedback (RLHF) has achieved notable success in steering models, […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Haiyang Liu, Zhan Xu, Fa-Ting Hong, Hsin-Ping Huang, Yi Zhou | Summary: We present Video Motion Graphs, a system designed to generate realistic human motion videos. Using a reference video and conditional signals such as music or motion tags, the system synthesizes new videos by first retrieving […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Allyson Bieryla, Jiayin Dong, George Zhou, Jason D. Eastman, L. C. Mayorga | Summary: We report the discovery and characterization of TOI-2005b, a warm Jupiter on an eccentric (e~0.59), 17.3-day orbit around a V_mag = 9.867 rapidly rotating F-star. The object was detected as a candidate by […]

Kavli Affiliate: David N. Spergel | First 5 Authors: Bernardita Ried Guachalla, Emmanuel Schaan, Boryana Hadzhiyska, Simone Ferraro, Jessica N. Aguilar | Summary: The gas density profile around galaxies, shaped by feedback and affecting the galaxy lensing signal, is imprinted on the cosmic microwave background (CMB) by the kinematic Sunyaev-Zel’dovich effect (kSZ). We precisely measure […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Tomohiro Fujita, Ryodai Kawaguchi, Misao Sasaki, Yuichiro Tada, | Summary: We consider models of inflation that contain a transient non-slow-roll stage and investigate the conditions under which a dip appears in the power spectrum of the curvature perturbation. Using the $delta N$ formalism, we derive a general […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Vicharit Yingcharoenrat, Ying-li Zhang, , | Summary: Recently, it was shown that in the absence of gravity there exist non-$O(4)$-symmetric instanton solutions with finite action beyond Coleman’s instantons. In this paper, focusing on the false-vacuum decay in a single scalar field in flat Euclidean space, […]
