Fibroblast Transcriptomics in Molecular Diagnostics of a Comprehensive Dystonia Cohort

open access: yesAnnals of Neurology, EarlyView.
Objective Genomic sequencing leaves >50% of dystonia‐affected individuals without a diagnosis. Where DNA‐oriented approaches remain insufficient, integrating multiomics is essential to advance genome interpretation. Herein, we incorporated RNA sequencing (RNA‐seq) data from 167 patients with dystonia across a range of ages and presentations. Methods We

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).
