From Chaos to Man

Hyperlabyrinth chaos: from chaotic walks to spatiotemporal chaos.

In this paper we examine a very simple and elegant example of high-dimensional chaos in a coupled array of flows in ring architecture that is cyclically symmetric and can also be viewed as an N-dimensional spatially infinite labyrinth (a "hyperlabyrinth"). The scaling laws of the largest Lyapunov exponent, the Kaplan-Yorke dimension, and the metric entropy are investigated in the high-dimension...

Extrapolation from mouse to man.

Despite the above caveat, the impressive new technology described by Gupta et al1 in this issue of Circulation: Cardiovascular Imaging should help to resolve a number of issues relative to the hypothesis that the failing heart is energy starved and that depressed high-energy phosphate flux through the creatine kinase (CK) system is a causative factor.2,3 It will allow longitudinal measurements ...

From Mummies to Modern Man

From Ötzi, the Tyrolean Iceman, to the royal mummies of pharaohs Akhenaten and Tutankhamun, genetic and genomic analyses of ancient deoxyribonucleic acid have shed light on the social and environmental influences on life and longevity, population dynamics, migratory patterns, dietary habits, putative and actual causes of death, and the susceptibility to congenital and acquired diseases during l...
