Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Kazuki Kannaka, Kazuki Kannaka, , , | Summary: Let $X=G/H$ be a homogeneous space of a Lie group $G$. When the isotropy subgroup $H$ is non-compact, a discrete subgroup $Gamma$ may fail to act properly discontinuously on $X$. In this article, we address the following question: in […]

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Zhuo Li, , , | Summary: Functional ultrasound (fUS) is a neuroimaging technique known for its high spatiotemporal resolution, enabling non-invasive observation of brain activity through neurovascular coupling. Despite its potential in clinical applications such as neonatal monitoring and intraoperative guidance, the development of fUS […]

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: 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 […]
