1. Clusters of urban crime and safety in transport nodes
Abstract : The objective of the thesis is to provide a better understanding of the safety conditions inurban environments, particularly related to those found in transport nodes, in this case,underground stations, and surrounding areas1. First, the study starts with an analysis of theoverall city, identifying concentrations of crime in the urban fabric and then focusing on thecriminogenic conditions at and around underground stations.

2. Prognostic and epidemiological factors in childhood leukemia : studies of p53 and MDM2 expression and of space-time clustering
Abstract : Although cure rates in acute childhood leukaemias have improved it remains a challenge to understand how molecular aberrations influence the prognosis of leukaemia and thus the choice of optimal therapy. Some studies have suggested that dysfunction of the tumour suppressor gene p53 or the oncogene MDM2 could indicate disease progression in children with leukaemia. READ MORE

3. On the Einstein-Vlasov system: Stationary Solutions and Small Data Solutions with Charged and Massless Particles
Abstract : The Vlasov matter model describes an ensemble of collisionless particles moving through space-time. These particles interact via the gravitational field which they create collectively. In the framework of General Relativity this gravitational field is described by space-time curvature. READ MORE
