Magnetoelectrochemical modulation of pre-organization processes in a 4,4′-dinitrobiphenyl azacrown macrocyclic lactam
2004
A magnetoelectrochemical effect consisting on the modulation of the reaction rate of pre-organization reactions in a 4,4′-dinitrobiphenyl azacrown lactam is described. The electrochemical response of that compound in DMSO solution at microelectrodes consists in two successive dinitrobiphenyl-centred one-electron transfer processes at −0.9 and −1.6 V vs. AgCl/Ag involving the transition from the dihedral geometry of the neutral starting compound to the planar geometry of the final dianion, resulting in an overall ECE mechanism. In the presence of moderate (0.05–0.2 T) static magnetic fields, the second electron transfer process decreases significantly, the apparent rate constant of the dihed…
La realidad virtual en las intervenciones psicológicas con pacientes oncológicos
2014
El objetivo de este trabajo es presentar las principales aportaciones de la Realidad Virtual (RV) en el tratamiento psicologico con pacientes oncologicos, y describir un programa de intervencion que utiliza esta tecnologia para promover bienestar emocional en pacientes hospitalizados. La RV se presenta como una prometedora herramienta de apoyo al paciente oncologico. Diversos estudios plantean su utilidad para hacer algunos tratamientos medicos mas tolerables, para reducir los niveles de distres y dolor, asi como promover mayores niveles de emociones positivas. Se ha empleado principalmente con pacientes ambulatorios, existiendo una menor proporcion de propuestas dirigidas al periodo de hos…

A chemical and electrochemical multivalent memory made from FeNi3-graphene nanocomposites
2014
FeNi3-graphene nanocomposites present in acetonitrile solutions a redox couple with an electrochemical hysteresis of 2.4 V between the oxidation and the reduction maxima. In view of the high energy required for the reverse transitions, they are here proposed as chemical multilevel memories: permanent, after drying, or erasable in electrolytes, respectively. Keywords: FeNi3-graphene nanocomposites, Voltammetry, Coulovoltammetry, Redox couple, Redox hysteresis
Evaluating the feasibility of the Italian version of the computerized interactive remediation of cognition training for schizophrenia (circuits)
2020
Background: Circuits is a computerized cognitive remediation program for individuals with schizophrenia. this study aimed to evaluate the feasibility of the italian version of circuits. MethODs: Feasibility was measured through ad-hoc questionnaires in a non-clinical sample (N.=30; target-score 70%; study 1); in patients with schizophrenia (N.=5; target-score 60%; study 2) and cr therapists (N.=3; target-score 60%; study 2). study 3 was a pilot study investigating: 1) enrolment, compliance, and retention rates; 2) satisfaction; 3) potential post-treatment and follow-up improvements in patients with schizophrenia (N.=20). these results were used to estimate sample size and feasibility for a …
Non-linear System Identification with Composite Relevance Vector Machines
2007
Nonlinear system identification based on relevance vector machines (RVMs) has been traditionally addressed by stacking the input and/or output regressors and then performing standard RVM regression. This letter introduces a full family of composite kernels in order to integrate the input and output information in the mapping function efficiently and hence generalize the standard approach. An improved trade-off between accuracy and sparsity is obtained in several benchmark problems. Also, the RVM yields confidence intervals for the predictions, and it is less sensitive to free parameter selection. Teoría de la Señal y Comunicaciones
Early rehabilitation of cancer patients - a randomized controlled intervention study.
2013
Published version of an article in the journal: BMC Cancer. Also available from the publisher at: http://dx.doi.org/10.1186/1471-2407-13-9 Open access Background: Faced with a life-threatening illness, such as cancer, many patients develop stress symptoms, i.e. avoidance behaviour, intrusive thoughts and worry. Stress management interventions have proven to be effective; however, they are mostly performed in group settings and it is commonly breast cancer patients who are studied. We hereby present the design of a randomized controlled trial (RCT) evaluating the effectiveness and cost-effectiveness of an individual stress-management intervention with a stepped-care approach in several cance…
Residence Time Distribution of Solid Particles in a High-Aspect Ratio Multiple-Impeller Stirred Vessel
2003
Despite its importance, experimental information on the Residence Time Distribution (RTD) of solid particles in continuous-flow stirred vessels is still scant. In this work, experimental data on particle RTD in a high-aspect-ratio vessel stirred by three equally-spaced Rushton turbines, was obtained by means of a special technique named Twin System Approach (TSA). Quite surprisingly, results indicate that, among the various possibilities that could have been devised (e.g. 6, or 3, or 1 ideal tanks in series), the flow model closest to reality for the particle phase, at least in the experimental range here investigated, is that of a single perfectly stirred vessel.
