Data-efficient semi-supervised learning for flow estimation using unlabelled probe data
arXiv:2605.28245v2 Announce Type: replace Abstract: Estimating time-resolved velocity and pressure fields from Particle Image Velocimetry (PIV) remains challenging due to its limited temporal resolution in many applications. Data-driven approaches that combine snapshot PIV with high-frequency probe data have shown great promise in reconstructing the flow dynamics for advection-dominated flows; however, they typically exploit only the probe measurements directly synchronized with the PIV...
The First Human-Based In Vitro Flow Loop and Quantification for Fetal Aortic Hemodynamics
arXiv:2606.06801v1 Announce Type: new Abstract: Coarctation of the aorta (CoA) is a common congenital defect that remains difficult to diagnose prenatally due to subtle and evolving anatomical features. In the fetus, the ductus arteriosus creates a dual-inflow configuration that generates complex three-dimensional flow patterns not captured by standard imaging. Improved characterization of fetal hemodynamics may enhance diagnostic accuracy beyond anatomy-based assessment.
