Chaos for cardiac arrhythmias through a one-dimensional modulation equation for alternans

Schaeffer, David (AMER INST PHYSICS, 2010)

Instabilities in cardiac dynamics have been widely investigated in recent years. One facet of this work has studied chaotic behavior, especially possible correlations with fatal arrhythmias. Previously chaotic behavior was ...
Natural constructal emergence of vascular design with turbulent flow

Cetkin, E.; Bejan, Adrian (AMER INST PHYSICS, 2010)

Here, we show that vascular design emerges naturally when a volume is bathed by a single stream in turbulent flow. The stream enters the volume, spreads itself to bathe the volume, and then reconstitutes itself as a single ...
Scale-wise evolution of rainfall probability density functions fingerprints the rainfall generation mechanism

Molini, Annalisa; Katul, Gaby; Porporato, Amilcare (AMER GEOPHYSICAL UNION, 2010)

The cross-scale probabilistic structure of rainfall intensity records collected over time scales ranging from hours to decades at sites dominated by both convective and frontal systems is investigated. Across these sites, ...
