William B. White,Elizabeth L. Whiteaxially symmetric equilibria suggest that modes with high . and ., including interchange modes, may be equally critical in the search for stable high pressure configurations . They can be assessed via the Mercier criterion, which is concerned with modes localized about some rational surface

William B. White highlight the influence of adverse space weather conditions by presenting the Halloween Sun-Earth events and their associated effects in the terrestrial space and point out the importance of 3D physics-based MHD models in space weather forecast. Then we summarize three well-known frameworks, includ

Kurt L. Helf,Rickard A. Olsonontribution the hypothesis that the magnetic field by the action of the Lorentz force supresses Lagrangian chaos is checked by direct numerical simulations of the MHD equations. As a measure of the level of chaos the Lyapunov exponent of a set of 128 × 128 trajectories of fluid particles is computed

An Orientation to Mammoth Cave and This Volume,ecades before the cave is fully mapped. This cave is famous also for prehistoric artifacts left by Indian cavers up to 5000 years ago and for its role in American history during the War of 1812. Mammoth Cave has diverse cave-adapted wildlife, so much so that it is considered a global biodiversity ho
