We present an instability in vertically vibrated dilute wormlike micellar solutions. Above a critical driving acceleration the fluid forms elongated solitary domains of high amplitude waves. We model this instability using a Mathieu equation modified to account for the non-Newtonian character of the fluid. We find that our model successfully reproduces the observed transitions.

We investigate the possible character values of torsion units of thenormalized unit group of the integral group ring of Mathieu sporadic groupM22. We confirm the Kimmerle conjecture on prime graphs for this group andspecify the partial augmentations for possible counterexamples to the strongerZassenhaus conjecture.

Evolution is well underway in the area of teams. As Tannenbaum, Mathieu, Salas, and Cohen (2012) aptly convey, today’s teams are increasingly complex! Teams are no longer relatively straightforward extensions of individually-based jobs; rather, teams are increasingly capitalizing on technological advances joining together larger, more diverse, more highly specialized, and often distributed sets...
