Electro and gamma nuclear physics in Geant4

Adequate description of electro and gamma nuclear physics is of utmost importance in studies of electron beam-dumps and intense electron beam accelerators. I also is mandatory to describe neutron backgrounds and activation in linear colliders. This physics was elaborated in Geant4 over the last year, and now entered into the stage of practical application. In the Geant4 Photo-nuclear data base ...

A physics-based electro-thermal model for FS IGBT

Extracting information on CKM phases , electro - weak penguins and new physics from B →

We derive constraints for B → V V modes (V = vector meson) that allow a quantitative assessment of the contributions from electroweak penguins (EWP) and/or new physics. Interplay of direct CP with oscillation studies then leads to the extraction of the angles α and γ, using B → Kω(ρ) andB → ρω(φ) respectively, if by using our constraint equations it can be experimentally demonstrated that color...

Computational Challenges in Building Multi-Scale and Multi-Physics Models of Cardiac Electro-Mechanics.

Despite the evident multiphysics nature of the heart – it is an electrically controlled mechanical pump – most modeling studies considered electrophysiology and mechanics in isolation. In no small part, this is due to the formidable modeling challenges involved in building strongly coupled anatomically accurate and biophyically detailed multi-scale multi-physics models of cardiac electro-mechan...

Towards a physics-based modelling of the electro-mechanical coupling in EAPs

Due to the increasing number of industrial applications of electro-active polymers (EAPs), there is a growing need for electromechanical models which accurately capture their behavior. To this end, we compare the predicted behavior of EAPs undergoing homogenous deformations according to three electromechanical models. The first model is a continuum based model composed of the mechanical Gent mo...
