We propose a simple experiment to study delocalization and extinction in inhomogeneous biological systems. The nonlinear steady state for, say, a bacteria colony living on and near a patch of nutrient or favorable illumination ("oasis") in the presence of a drift term ("wind") is computed. The bacteria, described by a simple generalization of the Fisher equation, diffuse, divide A --> A + A, di...

1 By: Team MOAB Gwyn Jones, Steve Neebe, Justin Owen, and Sam Snyder Introduction: For this study, we applied our game theory tools to evaluate the likely strategic moves by key players driving consolidation in the financial exchange sector. Recently, the Deutsche Borse, a major European exchange, signed a merger agreement with the flagship US exchange, the NYSE Euronext, with the goal that t...

—Studies of the whirling disease epizootic in the upper Colorado River drainage have suggested that Windy Gap Reservoir is a source of the fish-infective actinospore of Myxobolus cerebralis. We divided the reservoir into four quadrants (12 zones) and conducted a core-sampling study to determine the spatial dynamics of actinospore production within the reservoir from late June to early November ...
