A Feature Tracking velocimetry technique applied to inclined negatively buoyant jets [PDF]

, 2014
We have applied a Feature Tracking Velocimetry (FTV) technique to measure displacements of particles on inclined negatively buoyant jets (INBJs), issuing from a circular sharp-edged orifice, in order to investigate, among the others, the symmetry ...

Deep Learning‐Based Particle Tracking Velocimetry (PTV) for Spherical and Non‐Spherical Particles: Application to Sediment Transport

Water Resources Research, Volume 62, Issue 5, -Not available-.
Abstract Particle‐resolved measurements in physical experiments are crucial to the study of sediment transport. Conventional particle tracking velocimetry (PTV) relies on template matching of simple shapes via intensity thresholding and nearest‐neighbor linking.

Reversible Neurological Manifestations Preceding Biochemical Deterioration in Postpartum HELLP Syndrome—A Case Report and Literature Review

The Journal of Clinical Hypertension, Volume 28, Issue 5, May 2026.
ABSTRACT Posterior reversible encephalopathy syndrome (PRES) is a rare but severe neurological complication associated with hypertensive disorders of pregnancy and HELLP syndrome. We report a postpartum case in which neurological manifestations preceded the full biochemical expression of HELLP syndrome. A 22‐year‐old primigravida was admitted at 36 + 0
