We simplify the Norris-Stroock[NS91] result for the tail asymptotics of the fundamental solution to the Cauchy problem for a parabolic equation with uniformly elliptic coefficients, when the operator is time-independent. Specifically, we show that we can replace their general Energy functional with 1 2 d(x, y), where d(., .) is the distance function on R associated with the Riemmanian metric a....

In sperm whales (Physeter catodon L. 1758) the nose is vastly hypertrophied, accounting for about one-third of the length or weight of an adult male. Norris and Harvey [in Animal Orientation and Navigation, NASA SP-262 (1972), pp. 397-417] ascribed a sound-generating function to this organ complex. A sound generator weighing upward of 10 tons and with a cross-section of 1 m is expected to gener...

I am pleased to have an opportunity to clarify my proposals for teaching Whole Science and assessing knowledge of the nature of science through seeking a well-informed analysis of case studies in the news (Allchin, 2011; assumed in page references below). In this, I echoed similar earlier proposals by Norris and Phillips (1994), Glynn and Muth (1994), Korpan, Bisanz, Bisanz and Henderson (1997)...

Adaptation of heart and lung weight to high altitudes has not been conclusively studied in bird populations of one species. Rensch (1931) concluded that the ratio of heart weight to body weight increases with altitude in certain tropical passerines. Moreau (1944), while agreeing that such a trend would be expected, maintained that Rensch’s data were unsatisfactory. Altitudinal differences in th...
