INTRODUCTION Genetic testing remains low among racial/ethnic minority populations in the United States. We aimed to determine the prevalence and correlates of awareness of direct-to-consumer (DTC) genetic tests and the prevalence of genetic test use in a population-based sample of adults in Puerto Rico. METHODS We analyzed data from adults aged 18 years… (More)
A recent publication [D.] describes the first controlled experiments measuring the growth of the magneto-Rayleigh–Taylor instability in fast ($100 ns) Z-pinch plasmas formed from initially solid aluminum tubes (liners). Sinusoidal perturbations on the surface of these liners with wavelengths of 25–400 lm were used to seed single-mode instabilities. The… (More)

The first controlled experiments measuring the growth of the magneto-Rayleigh-Taylor instability in fast (∼100 ns) Z-pinch plasmas are reported. Sinusoidal perturbations on the surface of an initially solid Al tube (liner) with wavelengths of 25-400 μm were used to seed the instability. Radiographs with 15 μm resolution captured the evolution of the… (More)
We investigated the high-carrier screening of macroscopic polarization fields in GaN quantum wells (QWs) using a variational wave function for electrons and holes. In particular, we studied of the influence of free-carrier screening on the photoluminescence (PL) energy emission and carrier lifetime in the QW. We show that the energy transition between… (More)
