Since then, random matrices have played a key role in von Neumann algebra theory (cf. [V8], [V9]). The main result of this paper is the following extension of... | [

For single stars, stellar winds are the only means of mass loss, and these are chiefly a function of the metallicity of the star. We discuss how metallicity, ... | [

Experimental measurements in Au+Au collisions at \sqrtsNN=130, 200 GeV establish the existence of strong medium effects on hadron production well into the perturbative regime. | [
