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, […]
Kavli Affiliate: Felix Fischer | First 5 Authors: Felix Fischer, Moonkwang Jeong, Tian Qiu, , | Summary: Magneto-oscillatory devices have been recently developed as very potent wireless miniature position trackers and sensors with an exceptional accuracy and sensing distance for surgical and robotic applications. However, it is still unclear to which extend a mechanically resonating […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Danté M. Hewitt, Mohit Bhardwaj, Alexa C. Gordon, Aida Kirichenko, Kenzie Nimmo | Summary: We present the localization and host galaxy of FRB 20190208A, a repeating source of fast radio bursts (FRBs) discovered using CHIME/FRB. As part of the PRECISE repeater localization program on the EVN, […]
Kavli Affiliate: Felix Fischer | First 5 Authors: Felix Fischer, Christian Gletter, Moonkwang Jeong, Tian Qiu, | Summary: Magnetism is widely used for the wireless localization and actuation of robots and devices for medical procedures. However, current static magnetic localization methods suffer from large required magnets and are limited to only five degrees of freedom […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Zhengli Wang, Shunshun Cao, Jiguang Lu, Yulan Liu, Xun Shi | Summary: We report the detection of an extreme flux decrease accompanied by clear dispersion measure (DM) and rotation measure (RM) variations for pulsar B1929+10 during the 110-minute radio observation with the Five-hundred-meter Aperture Spherical radio Telescope […]
