Measurement of electron beam transverse slice emittance using a focused beamline
High Power Laser Science and Engineering, 2023 A single-shot measurement of electron emittance was experimentally accomplished using a focused transfer line with a dipole. The betatron phase of electrons based on laser wakefield acceleration (LWFA) is energy dependent owing to the coupling of the ...

Ultra-high field neuroimaging in psychosis: A narrative review
Frontiers in Psychiatry, 2022 Schizophrenia and related psychoses are complex neuropsychiatric diseases representing dysconnectivity across multiple scales, through the micro (cellular), meso (brain network), manifest (behavioral), and social (interpersonal) levels. In vivo human neuroimaging, particularly at ultra-high field (UHF), offers unprecedented opportunity to examine ...
