Measurement of the Ge(d,n)As cross section from 2.1 MeV to 10 MeV.

This work reports experimental Ge(d,n)As cross sections producing Arsenic-71 (t = 65.3 h, 28% β), a potentially useful diagnostic radionuclide. Target stacks containing two Ge foils, a Ni monitor foil, and an Al degrader were irradiated with 5.

Cerebrovascular stiffness and flow dynamics in the presence of amyloid and tau biomarkers.

Introduction: This work investigated the relationship between cerebrovascular disease (CVD) markers and Alzheimer's disease (AD) biomarkers of amyloid beta deposition, and neurofibrillary tau tangles in subjects spanning the AD clinical spectrum.

Methods: A total of 136 subjects participated in this study. Four groups were established based on AD biomarker positivity from positron emission tomography (amyloid [A] and tau [T]) and clinical diagnosis (cognitively normal [CN] and impaired [IM]).

A simple scheme for generating nearly uniform distribution of antipodally symmetric points on the unit sphere.

A variant of the Thomson problem, which is about placing a set of points uniformly on the surface of a sphere, is that of generating uniformly distributed points on the sphere that are endowed with antipodal symmetry, i.e., if x is an element of the point set then -x is also an element of that point set.
