Develop monitors for MW-power proton beam at J-PARC extraction beamline for neutrino experiments [PDF]

arXiv
Intense and well-characterized neutrino sources, coupled with large and high-performance detectors, are essential for elucidating the unknowns in leptonic mixing through neutrino oscillation measurements. The J-PARC accelerator and neutrino extraction beamline have recently undergone upgrades, successfully delivering an 800-kW beam.

Multi-heterodyne differential absorption lidar based on dual-comb spectroscopy for simultaneous greenhouse gas and wind speed measurements [PDF]

arXiv
In a recent study [1], we demonstrated a multi-heterodyne differential absorption lidar (DIAL) for greenhouse gas monitoring utilizing solid targets. The multi-frequency absorption measurement was achieved using electro-optic dual-comb spectroscopy (DCS) with a minimal number of comb teeth to maximize the optical power per tooth.

Liraglutide for idiopathic intracranial hypertension: a real‐world propensity score‐matched study

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Idiopathic intracranial hypertension (IIH) is a neurological disorder predominantly affecting young women with obesity, characterized by elevated intracranial pressure. While current treatments include weight loss counseling, medical therapies, and surgical interventions, their limitations necessitate exploring novel therapeutic ...

Music Interventions in Hyperacute and Acute Stroke Patients: A Randomized Controlled Pilot Feasibility Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute

Cerebello‐Prefrontal Connectivity Underlying Cognitive Dysfunction in Spinocerebellar Ataxia Type 2

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Spinocerebellar ataxia type 2 (SCA2) is a hereditary cerebellar degenerative disorder, with motor and cognitive symptoms. The constellation of cognitive symptoms due to cerebellar degeneration is named cerebellar cognitive affective syndrome (CCAS), which has increasingly been recognized to profoundly impact patients' quality of life;
