Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Xinlei Zhou, Rihao Li, Meng Hu, Wenhui Wu | Summary: Despite the remarkable success of deep neural networks (DNNs), the security threat of adversarial attacks poses a significant challenge to the reliability of DNNs. By introducing randomness into different parts of DNNs, stochastic methods can […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Sunao Sugiyama, Toshiki Kurita, | Summary: Different cosmological probes, such as primary cosmic microwave background (CMB) anisotropies, CMB lensing, and cosmic shear, are sensitive to the primordial power spectrum (PPS) over different ranges of wavenumbers. In this paper, we combine the cosmic shear […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Chao Li, Taolei Wang, Jinyang Guo, Hanzhang Yang | Summary: The growing scale of data requires efficient memory subsystems with large memory capacity and high memory performance. Disaggregated architecture has become a promising solution for today’s cloud and edge computing for its scalability and elasticity. […]
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: Sara Seager | 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, […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yong Yang, Geraint F. Lewis, Denis Erkal, Ting S. Li, Andrew P. Li | Summary: The Ophiuchus stellar stream presents a puzzle due to its complicated morphology, with a substructure perpendicular to the main track (spur), a broadened tail (fanning), and a shorter than expected angular […]
