Some Problems concerning Reflexive Operator Algebras

We discuss below some problems concerning a certain class of algebras of operators on complex Banach space. Each algebra of the class arises from a lattice of subspaces of the underlying space (in a way that will soon be made precise) and most of the problems are of the fonn: find conditions, additional to those specified a priori, on the lattice of subspaces, which are both necessary and suffi...

New problems raised by increased pulse pressure.

There is now ample evidence that brachial artery pulse pressure (PP) is an independent predictor of cardiovascular (CV) outcomes, principally in subjects aged .59. This finding has been observed not only in European but also in American and Asiatic populations.
