Estudi de l'evolució i el tractament del càncer des d'una perspectiva de la biologia de sistemes

Serra Musach, Jordi (Date of defense: 2016-01-29)

Cancer can be defined as a family of complex disease characterized by a cellular hyperproliferation and the capacity of the cell to invade surrounding tissue and metastasize to other organs in the body. The development and ...

The embedding problem for Markov matrices

Roca Lacostena, Jordi (Date of defense: 2021-05-18)

The goal of this thesis is to solve the embedding problem for Markov matrices, posed by Gustav Elfving in1937. A Markov matrix is non-negative square matrix whose rows sum to 1. We say that such a matrix M is embeddable ...

The variational approach to brittle fracture in materials with anisotropic surface energy and in thin sheets

Li, Bin (Date of defense: 2016-03-08)

Fracture mechanics of brittle materials has focused on bulk materials with isotropic surface energy. In this situation different physical principles for crack path selection are very similar or even equivalent. The situation ...
