New approaches to risk stratification after myocardial infarction.

Journal of cardiovascular pharmacology

Breithardt G, Borggrefe M, Fetsch T, Budde T.
PMID: 1723125
J Cardiovasc Pharmacol. 1991;17:S82-6.

Parameters to assess the presence of electrical instability after myocardial infarction include spontaneous ventricular arrhythmias, late potentials, and programmed ventricular stimulation. The accuracy of the long-term electrocardiogram in correctly identifying high-risk patients has been questioned because spontaneous ventricular arrhythmias...

Here we report for the first time on a complete simulation assisted "material to module" development of a high performance thermoelectric generator (TEG) based on the combination of a phase change material and established thermoelectrics yielding the compositions (1...

MORPHOLOGICAL AND MOLECULAR VARIATION ACROSS A MIGRATORY DIVIDE IN WILLOW WARBLERS, PHYLLOSCOPUS TROCHILUS.

Evolution; international journal of organic evolution

A migratory divide is a narrow region in which two populations showing different migratory directions meet arid presumably also mate and hybridize. Banding of willow warblers, Phylloscopus trochilus, in Europe has demonstrated a migratory divide latitudinally across central Scandinavia....
