DOI: 10.1109/tsp.2020.2973545
Abstract: In this article, the goal is to design deterministic sampling patterns on the sphere and the rotation group and, thereby, construct sensing matrices for sparse recovery of band-limited functions. It is first shown that random… read more here.

DOI: 10.1371/journal.pone.0230654
Abstract: The turnout of the lower extremities is the major component of the classical ballet positions (CPs) and correctly is initiated in the hips. The aim of this research was to determine the differences in the… read more here.
