2019
RESUMEN: Objetivo: Analizar el tipo de información aportada por las diferentes tecnologías de la información y comunicación (TIC) disponibles para el análisis, gestión o evaluación de heridas crónicas y lesiones de origen neoplásico, así como su impacto en los cuidados de las mismas, en términos de valoración y resolución de las lesiones. Metodología: Se realizó una revisión sistemática usando las recomendaciones de la Cochrane Collaboration. Se utilizaron las bases de datos MEDLINE (a través de PubMed), Web Of Science y SCOPUS. La estrategia de búsqueda para …

LASSO regression via smooth L1-norm approximation
2010
This paper discusses estimation of regression model with LASSO penalty when the L1-norm is replaced with its parametric smooth approximation. The resulting parameter estimators are more manageable than those from standard LASSO, standard errors are easy computed via a sandwich formula, and the model degrees of freedom may be computed straightforwardly. Moreover the resulting objective function may be minimized using usual optimization algorithms for regular models, for instance Newton-Raphson or iterative least squares.
Factors explaining the interest margin in the banking sectors of the European Union
2003
Abstract This study analyses the interest margin in the principal European banking sectors (Germany, France, the United Kingdom, Italy and Spain) in the period 1993–2000 using a panel of 15,888 observations, identifying the fundamental elements affecting this margin. Our starting point is the methodology developed in the original study by Ho and Saunders [Journal of Financial and Quantitative Analysis XVI (1981) 581–600] and later extensions, but widened to take banks' operating costs explicitly into account. Also, unlike the usual practice in the literature, a direct measure of the degree of competition (Lerner index) in the different markets is used. The results show that the fall of marg…
Logos’ Centrality and Expression in Martyria as a Superior Form of Dialogue
2021
This paper describes some motivations and outlines some limits regarding the possibility and necessity of interreligious, interconfessional, and interideological dialogue, in an attempt to improve our understanding of Orthodox Christianity’s role in these important aspects of domestic and foreign politics. This study aims to resolve the divergent opinions that exist in the Orthodox Church regarding the possibility of remaining in this kind of dialogue. The ancient philosophical mode of dialogue and the modern one are analyzed: dialogue as debate and negotiation. The study begins from the analysis of some technical terms describing the social and spiritual dimensions of dialogue
Chemical Ecology of Egg Parasitoids Associated with True Bugs
2012
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera. Several species of heteropteran egg parasitoids are or may be important for biological pest control. Successful parasitism of insect herbivores by insect parasitoids arises through several phases of host searching, which lead female wasps to the vicinity of, or in contact with, their hosts. During the host location process, females encounter and explore a variety of stimuli, among which chemical cues (i.e., semiochemicals or infochemicals) play a pivotal role. Female parasitoids are under selecti…
On the Rock Partridge in the painting “Saint Jerome in the study” by Antonello da Messina.
2012
Pictorial work of Antonello da Messina during the Sicilian period (1455-60) is considered less fruitful and less mature than during his stay in Venice (ca 1474-1476). While some art critics consider the painting “Saint Jerome in the study” a work of the first period, others believe that it was produced during the Venice period. The Authors analysed the plumage characters of the Rock Partridge, Alectoris graeca, depicted with symbolic significance in the painting, to try the identification of the population which the subject used as model could belong to. However, they conclude that the identification as a Sicilian as well as an Alpine Rock Partridge is doubtful and in this case the plumage …
Chronic aspartame intake causes deficient glutathione synthesis and induces cxcl1 up-regulation in mice liver
2018
Reduced glutathione (GSH) depletion and inflammation have been linked to chronic aspartame consumption. However, the cause of aspartame-induced GSH depletion and the role of pro- and anti-inflammatory cytokines in aspartame-triggered inflammation are still unknown. The aims of this research were to investigate if aspartame causes GSH depletion due to deficient synthesis and also which pro- and anti-inflammatory genes are involved in aspartame-related inflammation in mice liver. Mice were divided into three groups: control, aspartame (80 mg kg-1, v.o., 3 months), aspartame treated with N-acetylcysteine (NAC) (1 mmol kg-1, i.p., last month). Aspartame markedly reduced GSH, γ-glutamylcysteine …
