Crashing waves of destruction: the cell cycle and APC(Cdh1) regulation of SCF(Skp2).
Coordination of events required for cell cycle progression is orchestrated in large part by the ubiquitin (Ub)-mediated destruction of key regulatory proteins such as cyclins and their inhibitors. Until now, the G1/S and mitotic phases of the cell cycle were thought to be controlled by discrete families of multisubunit Ub-ligases: SCF ligases controlled the G1 to S transition, whereas APC ligas...
متن کاملDestruction of spiral waves in chaotic media.
Spiral-wave breakup in strongly chaotic media with nonphase-coherent chaotic attractors is investigated. Spiral-wave dynamics is studied for the Rössler reaction diffusion equation as the local attractor changes from a phase-coherent to a funnel form. Stable spiral waves with an Archimedean structure are observed to persist even when the local chaotic attractor has a funnel form. The destructio...
متن کاملGrain Destruction in Interstellar Shock Waves
Interstellar shock waves can erode and destroy grains present in the shocked gas, primarily as the result of sputtering and grain-grain collisions. Uncertainties in current estimates of sputtering yields are reviewed. Results are presented for the simple case of sputtering of fast grains being stopped in cold gas. An upper limit is derived for sputtering of refractory grains in C-type MHD shock...
متن کاملDrug-Impaired Driving: Test Without Crashing
The use of driving simulators in clinical trials is an interesting new development for testing the effects of drugs on impairment. Medscape interviewed Gary G. Kay, PhD, Associate Professor, Department of Neurology, Georgetown University School of Medicine and President, Cognitive Research Corporation, concerning his company's simulator -the CRC MiniSimTM – and how it is being used in clinical ...
متن کاملBooming and Crashing Populations and Easter Island
The population of Easter Island grew steadily for some time and then suddenly decreased dramatically; humans almost disappeared from the island. This is not the sort of behavior predicted by the usual logistic differential equation model of an isolated population or by the predator-prey model for a population using resources. We present a mathematical model that predicts this type of behavior w...
