• Irreversible electroporation for the treatment of cardiac arrhythmias

  Sugrue, Alan; Maor, Elad; Ivorra Cano, Antoni, 1974-; Vaidya, Vaibhav; Witt, Chance; Kapa, Suraj; Asirvatham, Samuel (Taylor & Francis, 2018)

  Cardiac ablation is an established treatment modality for the management of patients with cardiac arrhythmias. Current approaches to cardiac ablation employ thermal based energy to achieve lesions (damage) within the ...
• Stochastic transitions into silence cause noise correlations in cortical circuits

  Mochol, Gabriela; Hermoso Mendizabal, Ainhoa; Sakata, Shuzo; Harris, Kenneth D.; De la Rocha, Jaime (National Academy of Sciences, 2015)

  The spiking activity of cortical neurons is highly variable. This variability is generally correlated among nearby neurons, an effect commonly interpreted to reflect the coactivation of neurons due to anatomically shared ...
• A Parabolic quasilinear problem for linear growth functionals

  Andreu, Fuensanta; Caselles, Vicente; Mazón, José (European Mathematical Society (EMS), 2002)

  We prove existence and uniqueness of solutions for the Dirichlet problem for quasilinear parabolic equations in divergent form for which the energy functional has linear growth. A typical example of energy functional we ...
• The Total variation flow in RN

  Bellettini, Giovanni; Caselles, Vicente; Novaga, Matteo (Elsevier, 2002)

  In this paper, we study the minimizing total variation flow ut=div(Du/∣Du∣) in N for initial data u0 in Lloc1(N), proving an existence and uniqueness result. Then we characterize all bounded sets Ω of finite perimeter in ...
• Total variation and cheeger sets in Gauss space

  Caselles, Vicente; Miranda, Michele; Novaga, Matteo (Elsevier, 2010)

  The aim of this paper is to study the isoperimetric problem with fixed volume inside convex sets and other related geometric variational problems in the Gauss space, in both the finite and infinite dimensional case. We ...
• Uniqueness of the cheeger set of a convex body

  Alter, François; Caselles, Vicente (Springer, 2009)

  We prove that if C C RN is an open bounded convex set, then there is only one Cheeger set inside C and it is convex. A Cheeger set of C is a set which minimizes the ratio perimeter over volume among all subsets of C.
• Some remarks on uniqueness and regularity of cheeger sets

  Caselles, Vicente; Chambolle, Antonin; Novaga, Matteo (European Mathematical Society (EMS), 2010)

  We show that generically the subsets of RN with finite volume RN have a unique Cheeger set, in the sense that there always exists a nearby set which has a unique Cheeger set. We also prove that Cheeger sets are C1,1, when ...
• The Volume preserving crystalline mean curvature flow of convex sets in RN

  Bellettinia, Giovanni; Caselles, Vicente; Chambolle, Antonin; Novaga, Matteo (Elsevier, 2009)

  We prove the existence of a volume preserving crystalline mean curvature flat flow starting from a compact convex set and its convergence, modulo a time-dependent translation, to a Wulff shape with the corresponding volume. ...
• The Tree of shapes of an image

  Ballester, Coloma; Caselles, Vicente; Monasse, Pascal (EDP Sciences, 2003)

  In [CITE], Kronrod proves that the connected components of isolevel sets of a continuous function can be endowed with a tree structure. Obviously, the connected components of upper level sets are an inclusion tree, and the ...
• On the relativistic heat equation in one space dimension

  Carrillo, José; Caselles, Vicente; Moll, Salvador (2013)

  We study the relativistic heat equation in one space dimension. We prove a local regularity result when the initial datum is locally Lipschitz in its support. We propose a numerical scheme that captures the known features ...
