An hemodynamic work bench for in-vitro measurements in arterial bifurcations: experimental results and comparison with the output of a simplified CFD model.

To quantify fluid-structure interactions in arterial walls, from a biomechanical standpoint, a complete characterization of blood flow, shear stress in the interface between blood and endothelium, wall elasticity and wall stresses distribution are needed.

The excitation functional for magnetic stimulation of fibers.

Threshold problems in electric stimulation of nerve and muscle fibers have been studied from a theoretical standpoint using the excitation functional. Here the excitation functional is extended to magnetic stimulation of excitable nerve and muscle fibers. A unified derivation of the functional is done, for (non myelinated) nerve and muscle fibers, by means of the nonlinear cable equation with a Fitzhugh-Nagumo membrane model and a generalized Rattay's activating function. The identification problem of the excitation functional for magnetic stimulation, from strength-duration experimental data, is briefly considered.
