TL;DR: In this paper, a revised atomic deexcitation framework for the Geant4 general purpose Monte Carlo toolkit capable of simulating full Auger de-excitation cascades was implemented.
Journal ArticleDOI
Monte Carlo simulation of energy-deposit clustering for ions of the same LET in liquid water
Ziad Francis,Sebastien Incerti,Vladimir Ivanchenko,Christophe Champion,M. Karamitros,Mario A. Bernal,Z. El Bitar +6 more
TL;DR: A Monte Carlo study of energy depositions due to protons, alpha particles and carbon ions of the same linear-energy-transfer (LET) in liquid water using the Geant4-DNA toolkit and an adapted version of the DBSCAN clustering algorithm.
Journal ArticleDOI
Physical models implemented in the GEANT4-DNA extension of the GEANT-4 toolkit for calculating initial radiation damage at the molecular level.
TL;DR: The so-called Geant4-DNA extension is described, including a set of processes and models adapted in this study and permitting the simulation of electron, proton and alpha particle interactions in liquid water.
Journal ArticleDOI
A study on the physicochemical parameters for Penicillium expansum growth and patulin production: effect of temperature, pH, and water activity.

TL;DR: A mathematical model allowing the estimation of the P. expansum growth rate according to temperature, a W, and pH, was developed and tested successfully and could be exploited by apple growers and the industrialists of fruit juices in order to predict the development of P. expandum during storage and apple processing.
Journal ArticleDOI

TL;DR: This work has recently developed a fully integrated MC simulation that calculates early single strand breaks and double strand breaks in a fractal chromatin based human cell nucleus model that is almost equivalent to past MC simulations when considering direct/indirect strand break fraction, DSB yields and fragment distribution.
