On the time schedule of Brownian Flights
In [GKL06] a connection is established between the statistics of the long flight lengths ans the geometry of the long molecules (more precisely their Minkowski dimension). This connection has been made rigorous in [BLZ09]. These two papers concern almost exclusively lengths. But the NMR relaxation allows only to measure time. Some heuristic link between time and length was used in [GKL06]. The ...
متن کاملBrownian flights over a fractal nest and first-passage statistics on irregular surfaces.
The diffusive motion of Brownian particles near irregular interfaces plays a crucial role in various transport phenomena in nature and industry. Most diffusion-reaction processes in confining interfacial systems involve a sequence of Brownian flights in the bulk, connecting successive hits with the interface (Brownian bridges). The statistics of times and displacements separating two interface ...
متن کاملAngle-closure glaucoma on long-haul flights.
IMPORTANCE Unlike other modes of long-distance travel, long-haul flights delay urgent, specialist medical treatment until the destination is reached or the plane is diverted. Angle-closure glaucoma (ACG) occurring during those flights results in considerable morbidity and may cause permanent visual loss. It is preventable in patients with risk factors but may be an underrecognized and underrepo...
متن کاملSpreading Depression Sends Microglia on Lévy Flights
Spreading depression (SD) is thought to cause migraine aura, and perhaps migraine, and includes a transient loss of synaptic activity preceded and followed by increased neuronal excitability. Activated microglia influence neuronal activity and play an important role in homeostatic synaptic scaling via release of cytokines. Furthermore, enhanced neuronal function activates microglia to not only ...
متن کاملForaging flights.
First, he tracked basking sharks—filterfeeding leviathans that look like supersized great whites—in the coastal waters near Great Britain, and then Atlantic cod, leatherback turtles, Magellanic penguins, and bigeye tuna. He’s wrangled and tagged ocean sunfish, blue sharks, and shortfin mako sharks (and claims success by the fact that he still has all his fingers). Only after David Sims had exha...
