A higher-order numerical framework for stochastic simulation of chemical reaction systems

Background: In this paper, we present a framework for improving the accuracy of fixed-step methods for Monte Carlo simulation of discrete stochastic chemical kinetics. Stochasticity is ubiquitous in many areas of cell biology, for example in gene regulatio ...

EM SIMULATIONS IN BEAM COUPLING IMPEDANCE STUDIES: SOME EXAMPLES OF APPLICATION

Carlo Zannini, Giovanni Rumolo

In the frame of the SPS upgrade an accurate impedance model is needed in order to predict the instability threshold and if necessary to start a campaign of impedance reduction. Analytical models, 3-D simulations and bench measurements are used to estimate ...

Locality and universality in gyrokinetic turbulence

Laurent Villard, Stephan Brunner

The nature of nonlinear interactions in gyrokinetic (GK) turbulence, driven by the ion-temperature gradient instability, is investigated using direct numerical simulations in toroidal flux tube geometry. To account for the level of separation existing betw ...
