Suspensions of homology spheres
This article is one of three highly influential articles on the topology of manifolds written by Robert D. Edwards in the 1970’s but never published. This article “Suspensions of homology spheres” presents the initial solutions of the fabled Double Suspension Conjecture. The article “Approximating certain cell-like maps by homeomorphisms” presents the definitive theorem on the recognition of ma...
متن کاملLiquid crystal domains and thixotropy of filamentous actin suspensions.
The thixotropic properties of filamentous actin suspensions were examined by a step-function shearing protocol. Samples of purified filamentous actin were sheared at 0.2 sec-1 in a cone and plate rheometer. We noted a sharp stress overshoot upon the initiation of shear, indicative of a gel state, and a nearly instantaneous drop to zero stress upon cessation of shear. Stress-overshoot recovery w...
متن کاملEffective conductivity of suspensions of overlapping spheres
An accurate first-passage simulation technique formulated by the authors [J. Appl. Phys. 68, 3892 (1990)] is employed to compute the effective conductivity LT, of distributions of penetrable (or overlapping) spheres of conductivity a, in a matrix of conductivity (TV. Clustering of particles in this model results in a generally intricate topology for virtually the entire range of sphere volume f...

Emanuela Del Gado ETH Zürich Institut für Baustoffe (IfB), Schafmattstrasse 6 CH-8093 Zürich/Switzerland. [email protected] Gelation of Brownian and non-Brownian suspensions Modeling and numerical simulations gain significant insight into local processes and physical mechanisms underlying the interplay of gelation and flocculation in colloidal suspensions. We study local rearrangements, ...
متن کاملDiffusion of spheres in isotropic and nematic suspensions of rods.
Diffusion of a small tracer sphere (apoferritin) in isotropic and nematic networks [of fd virus] is discussed. For a tracer sphere that is smaller than the mesh size of the network, screened hydrodynamic interactions between the sphere and the network determine its diffusion coefficient. A theory is developed for such interactions as well as their relation to the long-time self-diffusion coeffi...
