The purpose of this study was to explore the complex flow structure a novel active-type micromixer that based on concept of Wankle-type rotor. The characteristics of this micromixer are two folds; a rapid mixing of reagents in a limited space due to the generation of multiple vortices and a graduate increment in dynamic pressure as the mixed reagents is delivered to the output ports. Present mi...

A rapid and simple technique for the detection of latent RNA tumor viruses has been described. It is based on phenotypic mixing between the latent agent (s) and a nondefective strain of RSV used as indicator virus. Most of the embryos from two different chicken lines tested so far contain such agents. According to their host range and serological properties they belong to subgroup E. The phenot...

Motivated by the ‘subgraphs world’ view of the ferromagnetic Ising model, we develop a general approach to studying mixing times of Glauber dynamics based on subset expansion expressions for a class of graph polynomials. With a canonical paths argument, we demonstrate that the chains defined within this framework mix rapidly upon graphs of bounded tree-width. This extends known results on rapid...
