Dust devils as observed by Mars Pathfinder
[1] Dust devils are localized meteorological phenomena frequently observed in terrestrial dry lands and desert landscapes as well as on Mars. They are low-pressure, warm core vortices that form at the bottom of convective plumes and loft dust from the surface. They move with the speed of the ambient wind and are tilted by wind shears. The Mars Pathfinder detected dust devils as dust plumes in t...

متن کاملRole of dust devils and orbital precession in closing the Martian dust cycle
[1] We use a general circulation model to simulate the role of dust devils on the Martian dust cycle as a function of orbital precession. We focus specifically on the two most recent epochs of 22,500 and 72,500 years ago when perihelion occurred near northern summer solstice. We find that dust devils dominate the dust cycle at these times and that while orbital precession does modulate the exch...
متن کاملComplex population dynamics and complex causation: devils, details and demography.
Population dynamics result from the interplay of density-independent and density-dependent processes. Understanding this interplay is important, especially for being able to predict near-term population trajectories for management. In recent years, the study of model systems-experimental, observational and theoretical-has shed considerable light on the way that the both density-dependent and -i...
متن کاملAmong the devils in the details are protease sequence, susceptibility, and structure in CRF02_AG viruses.
Diverse and distinct subtypes of HIV-1, including complex circulating recombi-nant forms (CRFs), have been outstrip-ping the prototypic subtype B isolates in much of Africa, Latin America, and Asia. However, in the course of drug development , preclinical in vitro studies, pivotal clinical trials, and analyasis of long-term treatment have largely focused on subtype B virus infection. With " sca...
