Further Observations of Terns' Eggs Enclosed by Hatched Eggshells

Further Observations

Initiation and termination of tachycardia was studied by electrical stimulation of the heart in 14 patients with ventricular tachycardia (VT) not related to acute myocardial infarction (group A) and in six patients in whom the tachycardia occurred within 24 hours after the onset of acute myocardial infarction (group B). Results favor re-entry as the mechanism of tachycardia in group A patients....

Vertex Cover: Further Observations and Further Improvements

Recently, there has been increasing interest and progress in lowering the worstcase time complexity for well-known NP-hard problems, particularly for the Vertex Cover problem. In this paper, new properties for the Vertex Cover problem are indicated, and several simple and new techniques are introduced, which lead to an improved algorithm of time O kn + 1 2852 for the problem. Our algorithm also...

Further Observations on Plague

Further observations on in vivo radioprotection of rats by selenourea.

Some chemical considerations have suggested that selenium-containing compounds should be good radioprotectors. Shimazu and Tappel reported that the selenoanalogues of cystine and methionine were effective in the radioprotection of proteins and amino acids in solution*. Earlier investigations in our labora­ tories have shown that selenourea has a radiopro­ tective effect in chemical systems 2, i...
