Spatially hybrid computations for streamer discharges: II. Fully 3D simulations [PDF]

, 2011
We recently have presented first physical predictions of a spatially hybrid model that follows the evolution of a negative streamer discharge in full three spatial dimensions; our spatially hybrid model couples a particle model in the high field region ...

Meltwater Intrusions Reveal Mechanisms for Rapid Submarine Melt at a Tidewater Glacier [PDF]

, 2019
Submarine melting has been implicated as a driver of glacier retreat and sea level rise, but to date melting has been difficult to observe and quantify. As a result, melt rates have been estimated from parameterizations that are largely unconstrained by ...

Markov Properties of Electrical Discharge Current Fluctuations in Plasma

, 2011
Using the Markovian method, we study the stochastic nature of electrical discharge current fluctuations in the Helium plasma. Sinusoidal trends are extracted from the data set by the Fourier-Detrended Fluctuation analysis and consequently cleaned data is
