Pure names are identifiers with no relation between them, except equality and inequality. In previous works we have extended P/T nets with the capability of creating and managing pure names, obtaining ?-PNs and proved that they are strictly well[...]texto impreso
Martínez de Toda Cabeza, Irene ; Miguélez, Lara ; Vida, Carmen ; Carro, Eva ; Fuente del Rey, Mónica de la | IOS Press | 2019-09-03Oxidative stress plays an essential and early role in the pathophysiology of Alzheimer’s disease (AD). Alterations in the redox state in AD and in mild cognitive impairment (MCI) patients appear in the brain and at peripheral level. Given that i[...]texto impreso
We give a generic framework to analyze the average-case running time for computing the so-called recurrent properties for pairs of binary search trees. Recurrent properties are algorithms that operate on pairs of trees testing some characteristi[...]texto impreso
The object of this paper is the study of blowing-up phenomena for the initial-boundary value problem (Pa): ut=uxx+?eu for (x,t)?(0,1)×(0,+?), u(0,t)=asin?t and u(1,t)=0 for t?[0,+?), u(x,0)=u0(x) for x?(0,1), where u0(x) is a continuous and boun[...]texto impreso

Clinical features include mild motor dysfunction with slow progression and cognitive impairment, frequent absence of fami[...]texto impreso
In this paper we study decidability of several extensions of P/T nets with name creation and/or replication. In particular, we study how to restrict the models of RN systems (P/T nets extended with replication, for which reachability is undecida[...]texto impreso
Gascueña, José M. ; Navarro, Elena ; Fernández Caballero, Antonio ; Fernández Sotos, Patricia ; Pavón Mestras, Juan | IOS Press | 2014-03An important issue in Ambient Intelligence (AmI) is the massive deployment of intelligent agents embedded in the environment which are adaptive to the users’ profiles, preferences and needs. This is why, the use of agent-oriented methodologies a[...]texto impreso
Fernández, Alberto ; Turrero, Agustín ; Zuluaga Arias, Pilar ; Gil Gregorio, Pedro ; Pozo, Francisco del ; Maestú, Fernando ; Moratti, Stephan | IOS Press | 2013New diagnostic criteria for Alzheimer's disease (AD) stress the role of in vivo biomarkers. Neurophysiological markers are usually not considered as such criteria, although theoretical and practical reasons would justify them. In order to assess[...]texto impreso
We study the relationship between name creation and replication in a setting of infinitestate communicating automata. By name creation we mean the capacity of dynamically producing pure names, with no relation between them other than equality or[...]texto impreso
Condor, Daniel F. ; Sanchez Alvarez, Katherine ; Bidman, Austin A. | IOS Press | 2018-11-30T22:50:34ZNursing informatics training has been progressively developing as a field in Latin America, each country with diverse approaches to its implementation. In Peru, this process has not yet taken place, so it is necessary to determine how universiti[...]texto impreso
We study the rigidification phenomenon for several thin slender bodies or shells, with a small curvature in the transversal direction to the main length, for which the propagation of singularities through the characteristics is of parabolic type[...]texto impreso

This paper is devoted to study the property of bservability for wave equations guaranteeing that the total energy of solutions may be estimated by means of the energy concentrated on a subset of the domain or of the boundary. We prove that this [...]texto impreso

Patients with 18p-/18q+ rearrangements share some clinical characteristics, while other ch[...]texto impreso
The aim of this study was to assess the changes of extracellular ATP levels during the progress of Alzheimer's disease by using a murine model of the disease. Retinal nucleotide release was measured from flattened whole-mounts stimulated with 59[...]
