By investigating stem cell models, we showed that induction of oscillation in normal ventricular myocytes by connecting stem cells to them is not possible. Induction of oscillations by stem cells was never demonstrated yet in well controlled conditions. Reported results [5],[4] demonstrate only increase of oscillation frequency (in cell culture...

We performed a numerical study of multiple scattering on regular fractal aggregates. We used a recursive method to compute the backscattered intensity resulting from a multiple scattered coherent wave. The wavelength of the incident field was supposed to be in the optical domain. The resulting backscattered intensity is analyzed in the light of...

Artificial biological pacemakers were developed and tested in canine ventricles. Next steps will require obtaining oscillations sensitive to external regulations, and robust with respect to long term drifts of expression levels of pacemaker currents and gap junctions. We introduce mathematical models intended to be used in parallel with the...

Pinning of vortices by defects plays an important role in various physical (superconductivity, superfluidity, etc.) or biological (propagation in cardiac muscle) situations. Which defects act as pinning centers? We propose a way to study this general problem by using an advection field to quantify the attraction between an obstacle and a...
