Kavli Affiliate: Ke Wang | First 5 Authors: Muhammad Khalil, Muhammad Khalil, , , | Summary: This paper presents a novel system architecture for hybrid satellite communications, integrating quantum key distribution (QKD) and classical radio frequency (RF) data transmission using a dual-band reconfigurable intelligent surface (RIS). The motivation is to address the growing need for […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Vance Wheeler, Vance Wheeler, , , | Summary: We use intergalactic medium (IGM) metallicity distributions from several state-of-the-art cosmological simulations of Milky Way analogs and a semi-analytic model of ultra-faint dwarf galaxy (UFD) formation to model the stellar metallicities of UFDs in MW-like environments. We study simulations […]
Kavli Affiliate: Seth Blackshaw | Authors: Haley Appel, Rogger Carmen-Orozco, Clayton Santiago, Thanh Hoang and Seth Blackshaw | Summary: The RNA-binding protein Ptbp1 has been proposed as a master regulator of neuronal fate, repressing neurogenesis through its effects on alternative splicing and miRNA maturation. While prior studies using RNA interference suggested that Ptbp1 loss promotes […]
Kavli Affiliate: Nathaniel Sawtell | Authors: Krista E Perks, Mariela D Petkova, Salomon Z Muller, Michael Genecin, Adishree Ghatare, Richard Schalek, Yuelong Wu, Michal Januszewski, Viren Jain, Jeff W Lichtman, LF Abbott and Nathaniel B Sawtell | Summary: Transitive inference (TI) is a cognitive process in which decisions are guided by internal representations of abstract […]
Kavli Affiliate: Lee McCuller | First 5 Authors: James W. Gardner, James W. Gardner, , , | Summary: Searching for a weak signal at an unknown frequency is a canonical task in experiments probing fundamental physics such as gravitational-wave observatories and ultra-light dark matter haloscopes. These state-of-the-art sensors are limited by quantum noise arising from […]
Kavli Affiliate: Leon Balents | First 5 Authors: Jens H. Nyhegn, Jens H. Nyhegn, , , | Summary: The complex interplay between charge and spin dynamics lies at the heart of strongly correlated quantum materials, and it is a fundamental topic in basic research with far reaching technological perspectives. We explore in this paper the […]
Kavli Affiliate: Kejia Lee | First 5 Authors: , , , , | Summary: In this study, we report multi-year polarization measurements of four repeating FRBs initially discovered by CHIME: FRBs~20190117A, 20190208A, 20190303A, and 20190417A. We observed the four repeating FRBs with FAST, detecting a total of 66 bursts. Two bursts from FRB~20190417A exhibit a […]
Kavli Affiliate: Lindsey Bleem | First 5 Authors: Ryan Walker, Ryan Walker, , , | Summary: A wide range of scientific imaging datasets benefit from human inspection for purposes ranging from prosaic-such as fault identification and quality inspection-to profound, enabling the discovery of new phenomena. As such, these datasets come in a wide variety of […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Keisuke Harigaya, Wayne Hu, Rayne Liu, Huangyu Xiao, | Summary: We show that enhancement of the axion relic abundance compared to the standard misalignment contribution generically leads to the production of nonzero momentum axion modes, resulting in warm dark matter behavior and enhanced isocurvature perturbations. It leads […]
Kavli Affiliate: Sara Seager | First 5 Authors: Samuel W. Yee, Samuel W. Yee, , , | Summary: We present the discovery of 30 transiting giant planets that were initially detected using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. These new planets orbit relatively bright ($G leq 12.5$) FGK host stars with orbital […]
