Kavli Affiliate: Sara Seager | First 5 Authors: Ana Glidden, Sara Seager, Jingcheng Huang, Janusz J. Petkowski, Sukrit Ranjan | Summary: The search for signs of life on other worlds has largely focused on terrestrial planets. Recent work, however, argues that life could exist in the atmospheres of temperate sub-Neptunes. Here, we evaluate the usefulness […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Chirag Falor, Paul L. Schechter, , , | Summary: The quadruple image configurations of gravitational lenses with vanishing ellipticity are examined. Even though such lenses asymptotically approach circularity, the configurations are stable if the position of the source relative to the vanishing diamond caustic is held […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Olivier Perdereau, Réza Ansari, Albert Stebbins, Peter T. Timbie, Xuelei Chen | Summary: We present the science case for surveys with the Tianlai dish array interferometer tuned to the $left[ 1300, 1400 right] mathrm{MHz}$ frequency range. Starting from a realistic generation of mock visibility data according to […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yuheng Jia, Sirui Tao, Ran Wang, Yongheng Wang, | Summary: Ensemble clustering integrates a set of base clustering results to generate a stronger one. Existing methods usually rely on a co-association (CA) matrix that measures how many times two samples are grouped into the same cluster according […]
Kavli Affiliate: Feng Wang | First 5 Authors: Jiaqi Lin, Feng Wang, Linhua Deng, Hui Deng, Ying Mei | Summary: The statistical study of the Coronal Mass Ejections (CMEs) is a hot topic in solar physics. To further reveal the temporal and spatial behaviors of the CMEs at different latitudes and heights, we analyzed the […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Steve Prabu, Paul J Hancock, Xiang Zhang, Steven J Tingay, Torrance Hodgson | Summary: Our previously reported survey of the Low Earth Orbit (LEO) environment using the Murchison Widefield Array (MWA) detected over 70 unique Resident Space Objects (RSOs) over multiple passes, from 20 hours of observations […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener, | Summary: This paper considers over-the-air federated learning (OTA-FL). OTA-FL exploits the superposition property of the wireless medium, and performs model aggregation over the air for free. Thus, it can greatly reduce the communication cost incurred in communicating model […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Yi Lin, Yang-hao Chan, Woojoo Lee, Li-Syuan Lu, Zhenglu Li | Summary: Optical excitation serves as a powerful approach to control the electronic structure of layered Van der Waals materials via many-body screening effects, induced by photoexcited free carriers, or via light-driven coherence, such as optical Stark […]
Kavli Affiliate: John Richardson | First 5 Authors: Nicholas Waytowich, James Hare, Vinicius G. Goecks, Mark Mittrick, John Richardson | Summary: Traditionally, learning from human demonstrations via direct behavior cloning can lead to high-performance policies given that the algorithm has access to large amounts of high-quality data covering the most likely scenarios to be encountered […]
