A penalized algorithm for event-specific rate models for recurrent events
Olivier Bouaziz, Agathe Guilloux
We introduce a covariate-specific total variation penalty in two semiparametric models for the rate function of recurrent event process. The two models are a stratified Cox model,…
The convex class of realisable unit covariances
Raphael Lachieze-Rey
This paper concerns the characterisation of second order marginals for random sets in a discrete setting. Under the instance of unit covariances, this problem possesses a combinato…
Numerical simulation on a cell polarisation model: the polar case
Vincent Calvez, Nicolas Meunier, Nicolas Muller +1
When it is polarised, a cell develops an asymmetric distribution of specific molecular markers, cytoskeleton and cell membrane shape. Polarisation can occur spontaneously or be tri…
Numerical simulation of the dynamics of molecular markers involved in cell polarisation
Vincent Calvez, Nicolas Meunier, Nicolas Muller +1
A cell is polarised when it has developed a main axis of organisation through the reorganisation of its cytosqueleton and its intracellular organelles. Polarisation can occur spont…
Cell polarisation model : the 1D case
Thomas Lepoutre, Nicolas Meunier, Nicolas Muller
We study the dynamics of a one-dimensional non-linear and non-local drift-di usion equation set in the half-line, with the coupling involving the trace value on the boundary. The i…
