Long period variables and mass loss in the globular clusters NGC 362 and NGC 2808 [PDF]
, 2011 The pulsation periods of long period variables (LPVs) depend on their mass and helium abundance as well as on their luminosity and metal abundance. Comparison of the observed periods of LPVs in globular clusters with models is capable of revealing the ...

Light dark matter in superfluid helium: Detection with multi-excitation production [PDF]
, 2016 © 2017 American Physical Society. We examine in depth a recent proposal to utilize superfluid helium for direct detection of sub-MeV mass dark matter. For sub-keV recoil energies, nuclear scattering events in liquid helium primarily deposit energy into ...

Advanced Functional Materials, EarlyView.This work addresses the challenge of current–voltage asymmetry in scalable laminated semitransparent organic photovoltaics (OPVs) for indoor applications. Vertical stratification of materials is shown to create an energy barrier, leading to performance differences under different illumination directions.
