    Singular manifolds of proteomic drivers controlling the dynamic of inflammatory bowel disease status

    Résumé : The conditions of an immune disease can often be represented by interaction graphs, but how those complex graphs are susceptible to interventions is still of utmost importance in areas such as reprogramming therapeutics. In this sense, module identification is an essential step towards understanding the whole graph architecture. The consideration of a general class of node dissimilarity measures related to the notion of topological overlap enables detecting ``driver’’ genes with high specificity in these modules. These module regulators can affect other nodes, potentially causing the entire system to change behaviour or fail. We provide a geometric framework based on singular manifolds explaining such situations in inflammatory bowel disease (IBD). IBD are important chronic disorders of the gastrointestinal tract which incidence is dramatically increasing worldwide. Our approach models those scenarios by reinterpreting the nonlinear dynamics intrinsic to real systems captured as compensatory responses to perturbations of a graph on its manifold of definition. Thus, we are able to reconfiguring the immune system to a desired target state. We illustrate the effectiveness of the strategy through the identification of potential drivers controlling the dynamic of IBD gene co-expression networks resulting from two high throughput proteome screenings.

    Mori theory for foliations on threefolds

    Résumé : We will review some of the basic ideas of the Minimal Model Program and discuss some recent work on the MMP for codimension 1 foliations on threefolds. We will then see some applications to the study of canonical foliation singularities and, time permitting, to the study of foliations with numerically trivial canonical class.
    This is joint work with Paolo Cascini.
