Observed epochal variations in X-ray lines from the O Supergiant $ζ$ Puppis do not require substantial changes in the wind mass flux

Posted by dbos MIT

Kavli Affiliate: David P. Huenemoerder | First 5 Authors: Sean J. Gunderson, Kenneth G. Gayley, David P. Huenemoerder, Pragati Pradhan, Nathan A. Miller | Summary: We fit the high resolution textit{Chandra} X-ray spectra of the O supergiant $zeta$ Puppis using the variable boundary condition (VBC) line model to test the stability of its mass-loss rate […]

RhythmFormer: Extracting rPPG Signals Based on Hierarchical Temporal Periodic Transformer

Posted by dbos Peking

Kavli Affiliate: Jiansheng Chen | First 5 Authors: Bochao Zou, Zizheng Guo, Jiansheng Chen, Huimin Ma, | Summary: Remote photoplethysmography (rPPG) is a non-contact method for detecting physiological signals based on facial videos, holding high potential in various applications such as healthcare, affective computing, anti-spoofing, etc. Due to the periodicity nature of rPPG, the long-range […]

Numerical Challenges in Modeling Gravothermal Collapse in Self-Interacting Dark Matter Halos

Posted by dbos Peking

Igor Palubski, Oren Slone, Manoj Kaplinghat, Mariangela Lisanti, Fangzhou Jiang | Summary: [[{“value”:”When dark matter has a large cross section for self scattering, halos can undergo a process known as gravothermal core collapse, where the inner core rapidly increases in density and temperature. To date, several methods have been used to implement Self-Interacting Dark Matter~(SIDM) […]

Stick to your Role! Stability of Personal Values Expressed in Large Language Models

Posted by dbos MIT

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Rémy Portelas, Masataka Sawayama, Peter Ford Dominey, Pierre-Yves Oudeyer | Summary: The standard way to study Large Language Models (LLMs) through benchmarks or psychology questionnaires is to provide many different queries from similar minimal contexts (e.g. multiple choice questions). However, due to LLM’s highly context-dependent […]

Affleck-Dine leptogenesis scenario for resonant production of sterile neutrino dark matter

Posted by klaurent Tokyo

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, , | Summary: Sterile neutrino is a fascinating candidate for dark matter. In this paper, we examine the Affleck-Dine (AD) leptogenesis scenario generating a large lepton asymmetry, which can induce the resonant production of sterile neutrino dark matter via the Shi-Fuller […]
