Kavli Affiliate: Susan E. Clark | First 5 Authors: Benjamin Beringue, Benjamin Beringue, , , | Summary: We discuss the model of astrophysical emission at millimeter wavelengths used to characterize foregrounds in the multi-frequency power spectra of the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6), expanding on Louis et al. (2025). We detail several […]
Kavli Affiliate: Wei Gao | First 5 Authors: Weixun Wang, Shaopan Xiong, Gengru Chen, Wei Gao, Sheng Guo | Summary: We introduce ROLL, an efficient, scalable, and user-friendly library designed for Reinforcement Learning Optimization for Large-scale Learning. ROLL caters to three primary user groups: tech pioneers aiming for cost-effective, fault-tolerant large-scale training, developers requiring flexible […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Xing Hu, Siyuan Chen, Xuming Huang, Qianqian Duan, LingKun Luo | Summary: With the growing application of computer vision in agriculture, image analysis has become essential for tasks such as crop health monitoring and pest detection. However, significant domain shifts caused by environmental variations, different crop types, […]
Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Aline U. Fornear, Marco Z. Di Fraia, Robert Gagliano | Summary: The Transiting Exoplanet Survey Satellite (TESS) has surveyed nearly the entire sky in Full-Frame Image mode with a time resolution of 200 seconds to 30 minutes and a temporal […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Niccolò Di Lalla, Niccolò Di Lalla, , , | Summary: We present the X-ray polarization observation of G21.5-0.9, a young Galactic supernova remnant (SNR), conducted with the Imaging X-ray Polarimetry Explorer (IXPE) in October 2023, with a total livetime of approximately 837 ks. Using different analysis […]
Kavli Affiliate: Peidong Yang | First 5 Authors: Hugo Laurell, Jonah R. Adelman, Elizaveta Yakovleva, Carl Hägglund, Kostiantyn Sopiha | Summary: In this study, coherent phonon motion is observed in bandgap excited CuIn$_{x}$Ga$_{(1-x)}$Se$_2$ (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectroscopy across the Se M$_{4,5}$ absorption edge. Two frequencies of coherent phonon motion are […]
Kavli Affiliate: Patricia Janak | Authors: Eric Garr, Yifeng Cheng, Andy Dong and Patricia H. Janak | Summary: It is commonly thought that drug addiction involves a transition to habitual control of action, where the choice to consume drugs becomes automatized and reflects a failure to deliberate over possible negative outcomes. Determining whether the pursuit […]
Kavli Affiliate: Sara Seager | First 5 Authors: Isobel S. Lockley, David J. Armstrong, Jorge Fernández Fernández, Sarah Millholland, Henrik Knierim | Summary: We present the discovery of three sub-Neptune planets around TOI-1117, a Sun-like star with mass $0.97pm0.02M_{odot}$, radius $1.05pm0.03R_{odot}$, age $4.42pm1.50$ Gyr and effective temperature $5635pm62$ K. Light curves from TESS and LCOGT […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Joe Davighi, Serah Moldovsky, Hitoshi Murayama, Christiane Scherb, Nudzeim Selimovic | Summary: We point out that a QCD-like dark sector can be coupled to the Standard Model by gauging the topological Skyrme current, which measures the dark baryon number in the infrared, to give a technically natural […]
Kavli Affiliate: Johannes Lehmann | First 5 Authors: Christel Baier, Rio Klatt, Sascha Klüppelholz, Johannes Lehmann, | Summary: As the complexity of software systems rises, methods for explaining their behaviour are becoming ever-more important. When a system fails, it is critical to determine which of its components are responsible for this failure. Within the verification […]
