BACKGROUND We hypothesized that the American Heart Association's metric of ideal cardiovascular health (CVH) predicts improved long-term functional status after adjusting for incident stroke and myocardial infarction. METHODS AND RESULTS In the prospective, multiethnic Northern Manhattan Study, stroke-free individuals in northern Manhattan aged ≥40 years had annual assessments of the primary ...

We investigate the structure of ideals generated by binomials (polynomials with at most two terms) and the schemes and varieties associated to them. The class of binomial ideals contains many classical examples from algebraic geometry, and it has numerous applications within and beyond pure mathematics. The ideals defining toric varieties are precisely the binomial prime ideals. Our main result...

We discuss the spectral properties of a sample of type-2 Seyfert galaxies based upon the analysis of ASCA data. In this paper we consider the sources for which the X-ray spectra appear to be dominated by the nuclear continuum, transmitted through a large column of absorbing material. We find that both Seyfert-2 galaxies and NELGs show iron Kα line profiles indicative of reprocessing of nuclear ...

An absorbing substrate of complex refractive index n(2) - jk(2) at wavelength lambda can be coated by an absorbing thin film of complex refractive index n(1) - jk(1) and thickness d to achieve zero reflection at normal incidence. For given n(2),k(2) multiple solutions (n(1),k(1),d/lambda) are found that correspond to infinitely many distinct antireflection layers. This is demonstrated for a Si ...

The physical basis of Brownian motion in translationally invariant media are well understood, and models based on this type of transport have been applied to the interpretation of an enormous variety of physical phenomena. There is likewise a large literature on Brownian motion in the presence of absorbing boundaries. Perfectly absorbing boundaries are known to change the properties of Brownian...
