Definition and properties of Lagrangian coherent structures from finite-time Lyapunov exponents in two-dimensional aperiodic flows
SC Shadden, F Lekien, JE Marsden - Physica D: Nonlinear Phenomena, 2005 - Elsevier
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 …

Quantification of hemodynamics in abdominal aortic aneurysms during rest and exercise using magnetic resonance imaging and computational fluid dynamics
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 …
