New proton emitter 188At implies an interaction unprecedented in heavy nuclei

open access: yesNature Communications
We report the discovery of a new atomic nucleus 188At, which is the heaviest proton-emitting isotope known to date. The new activity was observed through the 107Ag(84Sr, 3n)188At fusion-evaporation reaction using the focal-plane spectrometer of the gas ...

Study of fusion-fission dynamics in 19F+238U reaction

open access: yesEPJ Web of Conferences, 2016
Mass angle distribution measurements for 19F+238U reaction were carried out around the sub barrier energies. Mass angle correlation has not been observed at above and below the fusion barrier in present reaction.

White Matter Microstructural Abnormalities in Neonatal Onset Genetic Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Recent evidence indicates that epilepsy is associated with abnormal white matter. If seizures alter white matter, then the impact upon network function, epileptogenesis, and cognition could be pronounced in neonates undergoing rapid developmental myelination. Neonates with epilepsy due to nonstructural genetic causes provide a unique

The design and fabrication of 81.25 MHz RFQ for Low Energy Accelerator Facility

open access: yesNuclear Engineering and Technology, 2019
To provide high shunt impendence with low power losses, an 81.25 MHz continuous wave (CW) radio frequency quadrupole (RFQ) accelerator has been designed and machined as parts of the Low Energy Accelerator Facility (LEAF).

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

A renewable double plasma mirror for Petawatt-class lasers

open access: yesScientific Reports
Exceptional pulse contrast can be critical for ultraintense laser experiments, particularly when using solid density targets, and their use is becoming widespread. However, current plasma mirror technology is becoming inadequate for the new generation of

Giant Dipole Resonance in A ~ 144 mass region

open access: yesEPJ Web of Conferences, 2013
Exclusive measurement of giant dipole resonance (GDR) γ rays has been performed in 144Sm nucleus which was populated at near barrier energy using the heavy ion reaction of 28Si beam on 116Cd target. GDR γ rays were detected in coincidence with low energy

Upper Cervical Cord Area as a Biomarker of Conversion to Secondary Progressive Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study assessed whether upper cervical cord area (UCCA) measured on routine brain MRI can serve as a biomarker of conversion to SPMS. Methods This is a single‐center retrospective cohort study of RRMS patients with cross‐sectional and longitudinal analyses of clinical and MRI data. Future SPMS converters were matched by age, sex,
