Examining the brain scans in the context of other disease markers from spinal fluid
analyses and neuropsychiatric tests on the same participants showed that the rise and
spread of tau in the brain tracked more closely with declining mental
function than did amyloid.
Taking models of galaxies from the Hubble Space Telescope Ultra Deep Field (HUDF) and applying a correction for the HUDF point
spread function we generate lensed simulations of deep, opti... ▽ More We present a simulation
analysis of weak gravitational lensing flexion and shear measurement using shapelet decomposition, and identify differences between flexion and shear measurement noise in deep survey data.
