Advances in High Energy Physics, 2016 Lebed has given an argument that when a hydrogen atom is transported slowly to a different gravitational potential, it has a certain probability of emitting a photon. He proposes a space-based experiment to detect this effect.

Astronomical observations with a network of detectors of gravitational waves – II. Solution to the four and three detector problem [PDF]
Monthly Notices of the Royal Astronomical Society, 1989 Summary: In the theory of gravitational wave detection an important problem is the so-called inverse problem. It consists of determining the wave parameters from the responses of a suitable network of detectors. In this paper we solve the inverse problem with a network of (a) four detectors, and (b) three detectors, all located in the same place when ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Advanced Functional Materials, EarlyView.The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.
