[en] The case of multiple collisions in the discrete Boltzmann equation is considered. We establish sufficient conditions to be verified by the discrete models of the Boltzmann equation, so that the one-dimensional initial value problem possesses a global solution in time, under the constraint that the initial densities and initial mass are positive and bounded

[en] The papers in this section were presented at a joint session of symposium V on Applications of Multiple Scattering Theory and of Symposium P on Disordered Systems. They show that the ideas of scattering theory can help us to understand a very broad class of phenomena

[en] Exciton-mediated quantum state transfer between the periphery and the core of an extended dendrimer is investigated numerically. By mapping the dynamics onto that of a linear chain, it is shown that a localization-delocalization transition arises for a critical value of the generation number Gc ≈ 5. This transition originates in the quantum interferences experienced by the excitonic wave due to the multiple scatterings that arise each time the wave tunnels from one generation to another. These results suggest that only small-size dendrimers could be used for designing an efficient quantum communication protocol

[en] Electron scattering algorithms in Geant4 versions 9.4 and 9.5 were benchmarked by comparing scattered distributions against previously measured values at 13 and 20 MeV, for low, intermediate, and high atomic number materials. Several scattering models were used: Versions 93 and 95 of the Urban model, with different step size limits near boundaries; Goudsmit–Saunderson multiple scattering; and single scattering. The Urban93 and Urban95 models with a large step size limit (as in the Option 0 physics list) were found to give results most closely matching the experimental results. Scattered distributions using the Urban models were all narrower than measured by up to 6%, consistent with previous published simulations using EGSnrc. This is suggestive of a systematic difference between simulations and measurement. The magnitudes of the differences were similar to previously published results using Geant4, although there were differences in detail. In particular, the current results were typically 2% narrower than values. Results with the more restrictive step size limit in Option 3 were even more narrow, and close to those with single scattering. The Goudsmit–Saunderson multiple scattering model produced distributions up to 15% different from measured in Geant4 version 9.5 and up to 45% different in Geant4 version 9.4. (paper)
