Feshbach spectroscopy and analysis of the interaction potentials of ultracold sodium [PDF]

open access: yes, 2011
We have studied magnetic Feshbach resonances in an ultracold sample of Na prepared in the absolute hyperfine ground state. We report on the observation of three s-, eight d-, and three g-wave Feshbach resonances, including a more precise determination of

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Cardiac magnetic resonance spectroscopy

open access: yesCurrent Cardiology Reports, 2003
This review describes recent advances in cardiac magnetic resonance spectroscopy (MRS). MRS allows noninvasive characterization of the metabolic state of cardiac muscle, in both animal and human models. Recent experimental MRS studies have allowed new insights into the essential role of energetics in heart failure. Various new studies suggest a rapidly

Magnetotransport in a time-modulated double quantum point contact system

open access: yes, 2010
We report on a time-dependent Lippmann-Schwinger scattering theory that allows us to study the transport spectroscopy in a time-modulated double quantum point contact system in the presence of a perpendicular magnetic field.
