Zero-shot Medical Image Translation via Frequency-Guided Diffusion Models

Kavli Affiliate: Jing Wang | First 5 Authors: Yunxiang Li, Hua-Chieh Shao, Xiao Liang, Liyuan Chen, Ruiqi Li | Summary: Recently, the diffusion model has emerged as a superior generative model that can produce high quality and realistic images. However, for medical image translation, the existing diffusion models are deficient in accurately retaining structural information […]

Proposed host galaxies of repeating fast radio burst sources detected by CHIME/FRB

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, B. M. Gaensler, Paul Scholz, Daniele Michilli | Summary: We present a search for host galaxy associations for the third set of repeating fast radio burst (FRB) sources discovered by the CHIME/FRB Collaboration. Using the $sim$ 1 arcmin CHIME/FRB baseband […]

Simulating Cosmological Evolution by Quantum Quench of an Atomic BEC

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Han Fu, K. Levin, , | Summary: In cosmological evolution, it is the homogeneous scalar field (inflaton) that drives the universe to expand isotropically and to generate standard model particles. However, to simulate cosmology, atomic gas research has focused on the dynamics of Bose-Einstein condensates […]

Fabrication of a Monolithic 5-Meter Aluminum Reflector for Millimeter-Wavelength Observations of the Cosmic Microwave Background

Kavli Affiliate: Bradford Benson | First 5 Authors: Tyler Natoli, Bradford Benson, John Carlstrom, Eric Chauvin, Bruno Clavel | Summary: We have demonstrated the fabrication of a monolithic, 5-meter diameter, aluminum reflector with 17.4 $mu$m RMS surface error. The reflector was designed to avoid the problem of pickup due to scattering from panel gaps in […]
