A giant glitch from the magnetar SGR J1935+2154 before FRB 200428

Kavli Affiliate: Kejia Lee | First 5 Authors: Mingyu Ge, Yuan-Pei Yang, Fangjun Lu, Shiqi Zhou, Long Ji | Summary: Fast radio bursts (FRBs) are short pulses observed in radio frequencies usually originating from cosmological distances. The discovery of FRB 200428 and its X-ray counterpart from the Galactic magnetar SGR J1935+2154 suggests that at least […]

Mirror Dark Sector Solution of the Hubble Tension with Time-varying Fine-structure Constant

Kavli Affiliate: Joshua Frieman | First 5 Authors: John Zhang, Joshua Frieman, , , | Summary: We explore a model introduced by Cyr-Racine, Ge, and Knox (arXiv:2107.13000(2)) that resolves the Hubble tension by invoking a “mirror world" dark sector with energy density a fixed fraction of the “ordinary" sector of Lambda-CDM. Although it reconciles cosmic […]

Cholinergic Interneurons Drive Motivation by Promoting Dopamine Release in the Nucleus Accumbens

Kavli Affiliate: Joshua Berke | Authors: Ali Mohebi, Val L Collins and Joshua D Berke | Summary: Abstract Motivation to work for potential rewards is critically dependent on dopamine (DA) in the nucleus accumbens (NAc). DA release from NAc axons can be controlled by at least two distinct mechanisms: 1) action potentials propagating from DA […]

EdgeVision: Towards Collaborative Video Analytics on Distributed Edges for Performance Maximization

Kavli Affiliate: Ran Wang | First 5 Authors: Guanyu Gao, Yuqi Dong, Ran Wang, Xin Zhou, | Summary: Deep Neural Network (DNN)-based video analytics significantly improves recognition accuracy in computer vision applications. Deploying DNN models at edge nodes, closer to end users, reduces inference delay and minimizes bandwidth costs. However, these resource-constrained edge nodes may […]

Can 1D radiative equilibrium models of faculae be used for calculating contamination of transmission spectra?

Kavli Affiliate: Robert Cameron | First 5 Authors: Veronika Witzke, Alexander I. Shapiro, Nadiia M. Kostogryz, Robert Cameron, Benjamin V. Rackham | Summary: The reliable characterization of planetary atmospheres with transmission spectroscopy requires realistic modeling of stellar magnetic features, since features that are attributable to an exoplanet atmosphere could instead stem from the host star’s […]

Ultralight and ultra-stiff nano-cardboard panels: mechanical analysis, characterization, and design principles

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Jong-hyoung Kim, Lishuai Jin, Benjamin C. Schafer, Quan Jiao, Katia Bertoldi | Summary: We introduce a class of ultra-light and ultra-stiff sandwich panels designed for use in photophoretic levitation applications and investigate their mechanical behavior using both computational analyses and micro-mechanical testing. The sandwich panels consist of […]
