Jean - Sébastien Sereni ON FAIR EDGE DELETION PROBLEMS

In edge deletion problems, we are given a graph G and a graph property π and the task is to find a subset of edges the deletion of which results in a subgraph of G satisfying the property π. Typically the objective is to minimize the total number of deleted edges while in less common fair versions the objective is to minimize the maximum number of edges removed from a single vertex. We focus on...

We report on the case of a girl with type 1 Gaucher’s disease, treated from age 9 to 15 with highdose enzyme replacement therapy. This treatment did not avert the development of an extensive mutilating hepatic fibrosis warranting a liver transplantation, which was followed by death. In some cases of Gaucher’s disease, alternative strategies such as fractionated or further increased ERT, gene th...

XX IS SIFT SCALE INVARIANT ? Jean - Michel Morel

This note is devoted to a mathematical exploration of whether Lowe’s Scale-Invariant Feature Transform (SIFT) [21], a very successful image matching method, is similarity invariant as claimed. It is proved that the method is scale invariant only if the initial image blurs is exactly guessed. Yet, even a large error on the initial blur is quickly attenuated by this multiscale method, when the sc...

In the context of the π-calculus, open bisimulation is prominent and popular due to its congruence properties and its easy implementability. Motivated by the attempt to generalise it to the spi-calculus, we offer a new, more refined definition and show in how far it coincides with the original one.
