Martínez Carmona, Marina ; Izquierdo Barba, Isabel ; Colilla, Montserrat ; Vallet Regí, María | Elsevier | 2019-07-03The ability of bacteria to form biofilms hinders any conventional treatment for chronic infections and has serious socio-economic implications. For this purpose, a nanocarrier capable of overcoming the barrier of the mucopolysaccharide matrix of[...]![]()

In this article we examine the concentration and oscillation effects developed by high-frequency eigenfunctions of the Laplace operator in a compact Riemannian manifold. More precisely, we are interested in the structure of the possible invarian[...]![]()

Albert Albiol, Elvira ; Arenas Sánchez, Purificación ; Genaim, Samir ; Puebla, Germán ; Román Díez, Guillermo | Elsevier | 2014-10Static analysis which takes into account the values of data stored in the heap is considered complex and computationally intractable in practice. Thus, most static analyzers do not keep track of object fields nor of array contents, i.e., they ar[...]![]()

We present a model in which a hadron is represented as a bound state of several nonlinear Dirac fields which we identify with the quarks. These fields interact by a fourth order coupling term. We define a particle as any finite energy solitary w[...]![]()

The Invariant Subspace Problem for Hilbert spaces is a long-standing question and the use of universal operators in the sense of Rota has been one tool for studying the problem. The best known universal operators have been adjoints of analytic T[...]![]()
