Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Takuro Fujino, Satoru Takakura, Shahed Shayan Arani, Darcy Barron, Carlo Baccigalupi | Summary: At millimeter wavelengths, the atmospheric emission is circularly polarized owing to the Zeeman splitting of molecular oxygen by the Earth’s magnetic field. We report a measurement of the signal in the 150 GHz band […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Antonio Herrera-Martin, Radu V. Craiu, Gwendolyn M. Eadie, David C. Stenning, Derek Bingham | Summary: An important task in the study of fast radio bursts (FRBs) remains the automatic classification of repeating and non-repeating sources based on their morphological properties. We propose a statistical model that […]
Kavli Affiliate: Ke Wang | First 5 Authors: Siju Zhang, Tie Liu, Ke Wang, Annie Zavagno, Guido Garay | Summary: Fragmentation and evolution for the molecular shells of the compact HII regions are less explored compared to their evolved counterparts. We map nine compact HII regions with a typical diameter of 0.4 pc that are […]
Kavli Affiliate: Menno Witter | Authors: Paola Alemán-Andrade, Menno P. Witter, Ken-Ichiro Tsutsui and Shinya Ohara | Summary: Direct projections from the ventral hippocampus (vHPC) to the medial frontal cortex (MFC) play crucial roles in memory and emotional regulation. Using anterograde transsynaptic tracing and in vitro electrophysiology in mice, we document a previously unexplored pathway […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Marbely Micolta, Nuria Calvet, Thanawuth Thanathibodee, Gladis Magris C., Carlo F. Manara | Summary: We present a study of the abundance of calcium in the innermost disk of 70 T Tauri stars in the star-forming regions of Chamaeleon I, Lupus and Orion OB1b. We use calcium […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Kaia R. Atzberger, Sam A. Usman, Alexander P. Ji, Lara R. Cullinane, Denis Erkal | Summary: Chemical abundances of stellar streams can be used to determine the nature of a stream’s progenitor. Here we study the progenitor of the recently discovered Leiptr stellar stream, which was […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Ellen G. Zweibel, Nickolay Y. Gnedin, , | Summary: We investigate the 1D plane-parallel front connecting the warm ($10^4$ K) and hot ($10^6$ K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CRs) in shaping these transition layers. We […]
Kavli Affiliate: Wei Gao | First 5 Authors: Zhiyi Pan, Guoqing Liu, Wei Gao, Thomas H. Li, | Summary: The acquisition of inductive bias through point-level contrastive learning holds paramount significance in point cloud pre-training. However, the square growth in computational requirements with the scale of the point cloud poses a substantial impediment to the […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Fine-tuning pre-trained models has become the standard approach to endow them with specialized knowledge, but it poses fundamental challenges. In particular, textit{(i)} fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Alessandro Favero, Guillermo Ortiz-Jimenez, Francois Fleuret | Summary: Large pre-trained models exhibit impressive zero-shot performance across diverse tasks, but fine-tuning often leads to catastrophic forgetting, where improvements on a target domain degrade generalization on other tasks. To address this challenge, we introduce LiNeS, […]
