Multifractal images of the seismicity in the Ibero-Maghrebian region (westernmost boundary between the Eurasian and African plates)
(Tectonophysics, 2014-07)
The earthquake occurrence has a scale-invariant behavior that can be analyzed by means of a set of non-integer dimensions. The capacity dimension is related to the number of spatially distributed earthquakes, that is, to ...
Impact of psychiatric comorbidity on in the in-treatment outcomes of cocaine-dependent patients on therapeutic community
(Substance Abuse, 2014-04)
Background: This study aimed to explore the association between psychiatric comorbidity and treatment outcomes in therapeutic communities (TCs). Methods: A prospective longitudinal descriptive design was used. A baseline ...

Cocaine-induced psychotic symptoms in clinical setting
(Psychiatry Research, 2014-06)
Cocaine use is significantly associated with psychiatric co-morbidities of which psychotic symptoms are the most typical. The primary goal of this study is to estimate the life-time prevalence of cocaine-induced psychotic ...
H-Classics: characterizing the concept of citation classics through H-index
(Scientometrics, 2014-03)
Citation classics identify those highly cited papers which are an important reference point in a research field. To identify a paper as a citation classic we have to fix a citation threshold value. Usually, this threshold ...
¿Por qué vivimos más? Descomposición por causa de la esperanza de vida española de 1980 a 2009

Local convergence analysis of proximal Gauss-Newton method for penalized nonlinear least squares problems
(Applied Mathematics and Computation, 2014-08)
We present a local convergence analysis of the proximal Gauss-Newton method for solving penalized nonlinear least squares problems in a Hilbert space setting. Using more precise majorant conditions than in earlier studies ...
Local Convergence of the Gauss-Newton Method for Infective-Overdetermined Systems
(Journal of the Korean Mathematical Society, 2014-09)
We present, under a weak majorant condition, a local convergence analysis for the Gauss-Newton method for injective-overdetermined systems of equations in a Hilbert space setting. Our results provide under the same information ...
Calidad de vida relacionada con la salud en una muestra de médicos internos residentes que realizan guardias en un Servicio de Urgencias: una perspectiva de género
(Revista médica de Chile, 2014-02)
The high emotional burden of physicians working in emergency departments may affect their quality of life perception. Aim: To evaluate health related quality of life among resident physicians performing shifts at an emergency ...
Optimizing the applicability of a theorem by F. Potra for Newton-like methods
(Applied Mathematics and Computation, 2014-09)
We present a new sufficient semilocal convergence conditions for Newton-like methods in order to approximate a locally unique solution of an equation in a Banach space setting. This way, we expand the applicability of these ...
