This paper develops the theory and computation of Lagrangian Coherent Structures (LCS),
which are defined as ridges of Finite-Time Lyapunov Exponent (FTLE) fields. These ridges …

The emergence of deep learning has considerably advanced the state-of-the-art in cardiac
magnetic resonance (CMR) segmentation. Many techniques have been proposed over the …

Patient-specific cardiovascular simulation has become a paradigm in cardiovascular research
and is emerging as a powerful tool in basic, translational and clinical research. In this …

Abdominal aortic aneurysms (AAAs) affect 5–7% of older Americans. We hypothesize that
exercise may slow AAA growth by decreasing inflammatory burden, peripheral resistance, and …

In this paper we apply dynamical systems analyses and computational tools to fluid transport
in empirically measured vortex ring flows. Measurements of quasisteadily propagating …

… Shadden, Jerrold E. Marsden, and Reza Olfati-Saber … c) Combination.: We would like to
combine the reorientation algorithm (2) and the collision avoidance algorithm (3) so that the …

OBJECTIVES: The objective of this work is to evaluate the hemodynamic performance of a
new Y-graft modification of the extracardiac conduit Fontan operation. The performance of the …

Numerical simulations and experimental observations reveal that unsteady fluid systems
can be divided into regions of qualitatively different dynamics. The key to understanding …

Recent advances in blood flow modeling have provided highly resolved, four-dimensional
data of fluid mechanics in large vessels. The motivation for such modeling is often to better …

Stimulated by a recent controversy regarding pressure drops predicted in a giant aneurysm
with a proximal stenosis, the present study sought to assess variability in the prediction of …
