Viral complexes observed to be membrane associated rather than clumped by antibody were detected in a rotavirus-containing stool specimen by negative-stain electron microscopy. These "viral packets" were also observed in cell culture fluids after repeated passaging and contained up to 100 virions. Other stool specimens have been observed to contain similar packets of parvovirus-like particles. ...

In an effort to understand unusual power-law spectral slopes observed in some hypercompact HII regions, we consider the radio continuum energy distribution from an ensemble of spherical clumps. An analytic expression for the free-free emission from a single spherical clump is derived. The radio continuum slope (with Fν ∝ ν ) is governed by the population of clump optical depths N(τ), such that ...

The gravitational entropy of the Universe is large and subtle to calculate. A lower bound is well known from supermassive black holes at the centers of galaxies, but the remainder is harder to pin down. A parametric model of clumped matter entropy is provided. We suggest a new upper bound due to dark matter halos, that is far below the holographic bound, yet above that for the supermassive blac...

The gradient-flow dynamics of an arbitrary geometric quantity is derived using a generalization of Darcy’s Law. We consider flows in both Lagrangian and Eulerian formulations. The Lagrangian formulation includes a dissipative modification of fluid mechanics. Eulerian equations for self-organization of scalars, 1-forms and 2-forms are shown to reduce to nonlocal characteristic equations. We iden...

We report the MR findings in two patients with clinically and histologically proved Dejerine-Sottas disease. One patient had spinal involvement with multiple thickened and clumped nerve roots of the cauda equina; the second had multiple enlarged and enhancing cranial nerves. Although these findings are not specific for Dejerine-Sottas disease, they are suggestive of the diagnosis, which is furt...
