European Physical Journal C: Particles and Fields, 2019 The significance of the radial velocity effects on the leading-order gravitational frequency shift in some special cases was reported recently. This paper investigates the gravitational shift of frequency of light propagating in the equatorial plane of a

The Radial Velocities of Globular Clusters [PDF]
Proceedings of the National Academy of Sciences, 1930 The following discussion of the radial velocities of globular clusters originated in conversations which I had with Dr. Zwicky of the California Institute of Technology during my stay at the Mount Wilson Observatory. Since it depends essentially on the validity of Stromberg's solution for the motion of the sun relative to the system of the globular ...

CEPHEID PULSATIONS FROM RADIAL VELOCITY MEASUREMENTS
Odessa Astronomical Publications, 2017 We discuss the results of our many-year program of Cepheid radial velocities concerning the Hertzsprung sequence in radial-velocity curves, double-mode Cepheids, the period-radius relation, binary Cepheids.

The Death of Vulcan: NEID Reveals That the Planet Candidate Orbiting HD 26965 Is Stellar Activity
The Astronomical JournalWe revisit the long-studied radial velocity (RV) target HD 26965 using recent observations from the NASA-NSF “NEID” precision Doppler facility. Leveraging a suite of classical activity indicators, combined with line-by-line RV analyses, we demonstrate ...

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins
FEBS Open Bio, EarlyView.We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

The Diverse Neuromuscular Spectrum of VPS13A Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...
