ββ2ν decay in 48Ca
2001
[EN] A schematic study of the bb2n decay of 48Ca is made in a shell-model approach. The emphasis is especially put on the role of the spin-orbit potential in relation with the contribution of other terms in the strong interaction. This is discussed with a particular attention to the behavior of these ones under the SU(4) symmetry. Different methods in calculating the transition amplitude are also looked at with the aim to determine their reliability and, eventually, why they do not work. Further aspects relative to the failure of the operator expansion method to reproduce the results of more elaborate calculations are examined.
Cell-average WENO with progressive order of accuracy close to discontinuities with applications to signal processing
2020
In this paper we translate to the cell-average setting the algorithm for the point-value discretization presented in S. Amat, J. Ruiz, C.-W. Shu, D. F. Y\'a\~nez, A new WENO-2r algorithm with progressive order of accuracy close to discontinuities, submitted to SIAM J. Numer. Anal.. This new strategy tries to improve the results of WENO-($2r-1$) algorithm close to the singularities, resulting in an optimal order of accuracy at these zones. The main idea is to modify the optimal weights so that they have a nonlinear expression that depends on the position of the discontinuities. In this paper we study the application of the new algorithm to signal processing using Harten's multiresolution. Se…
Validation of the use of Actigraph GT3X accelerometers to estimate energy expenditure in full time manual wheelchair users with spinal cord injury.
2013
Study design: Cross-sectional validation study. Objectives: The goals of this study were to validate the use of accelerometers by means of multiple linear models (MLMs) to estimate the O2 consumption (VO2) in paraplegic persons and to determine the best placement for accelerometers on the human body. Setting: Non-hospitalized paraplegics’ community. Methods: Twenty participants (age=40.03 years, weight=75.8 kg and height=1.76 m) completed sedentary, propulsion and housework activities for 10 min each. A portable gas analyzer was used to record VO2. Additionally, four accelerometers (placed on the non-dominant chest, non-dominant waist and both wrists) were used to collect second-by-second a…
Objective evaluation of the width of source ensemble in virtual halls
2012
[EN] In this work, we study the effects of the width of the sound source in several acoustical virtual room models with different topologies, sizes and uses, calibrated with commercial software. To achieve this aim, a square distribution of sound sources with variable side length has been considered. We have auralized four channels of speech signal and musical signal in three different locations in each room. By using signal processing techniques, a comparison of multisource auralizations with the ones obtained from a single source in the middle of the stage is made. Also, the variations between the usual room parameters obtained from these simulations are analyzed, in order to show the eff…
El afrontamiento de los síntomas de burnout a través del significado de la tarea en profesionales que trabajan con personas con discapacidad intelect…
2021
This study examined an intervention that links task significance (one’s job has a positive impact on other people) to burnout symptoms of professionals working in organizations for individuals with intellectual disability. Professionals assigned to the experimental condition participated in teams designed to enhance the positive impact of their work on others (task significance). To do so, teams focused on a task to improve the quality of life of individuals with intellectual disability. Professionals assigned to the control condition did not participate in these teams, and they continued with their usual work. All the participating professionals answered a questionnaire about burnout…
Efficacy of a 12-Week Simeprevir Plus Peginterferon/Ribavirin (PR) Regimen in Treatment-Naïve Patients with Hepatitis C Virus (HCV) Genotype 4 (GT4) …
2017
Background HCV GT4 accounts for up to 20% of HCV infections worldwide. Simeprevir, given for 12 weeks as part of a 24- or 48-week combination regimen with PR is approved for the treatment of chronic HCV GT4 infection. Primary study objectives were assessment of efficacy and safety of simeprevir plus PR in treatment-naïve patients with HCV GT4 treated for 12 weeks. Primary efficacy outcome was sustained virologic response 12 weeks post-treatment (SVR12). Additional objectives included investigation of potential associations of rapid virologic response and baseline factors with SVR12. Methods This multicentre, open-label, single-arm study (NCT01846832) evaluated efficacy and safety of simepre…
La cronología de ἵνα con subjuntivo en expresión de mandato: la lengua de Sófocles, Eurípides y Jenofonte
2008
En este artículo el autor trata de señalar que la construcción de ἵνα más subjuntivo con valor de imperativo es anterior a la koiné. Asimismo trata de explicar su origen y sus fases a partir de un proceso de gramaticalización constatable, por ejemplo, en la lengua de Sófocles, Eurípides y Jenofonte. In this paper the author tries to point out that ἵνα with subjunctive as imperative is previous to koiné. Likewise he tries to explain its origin and phases starting from a grammaticalization process that is noticeable in the language of Sophocles, Euripides and Xenophon.
Characteristics of young offenders depending on the type of crime
2015
The aim of this study is to define a profile of juvenile offenders depending on the type of crime (against property or against persons), according to several socio-demographic variables, and a number of indicators of juvenile risk. Participants were 395 adolescents between the ages of 14 and 18 with a criminal record in the juvenile court over a two-year follow-up period. Results showed that in property-related offences the offender is more likely to be male, from an Eastern European country, and with inconsistent parenting. On the other hand, crimes against persons would be committed mostly by girls, Latin American or African juveniles, and with individual factors such as aggressive behavi…
Using random networks to study the dynamics of respiratory syncytial virus (RSV) in the Spanish region of Valencia
2011
[EN] Seasonal fluctuations in the incidence of several respiratory infections are a feature of epidemiological surveys all around the world. This phenomenon is characteristic of influenza and respiratory syncytial virus pandemics. However, the explanation of the seasonal outbreaks of these diseases remains poorly understood. Many statistical studies have been carried out in order to provide a correlation of the outbreaks with climatic or social factors without achieving a definitive conclusion. Here we show that, in a random social network, self-sustained seasonal epidemics emerge as a process modulated by the infection probability and the immunity period after recovering from the infection…
Application of the CIPP model in the study of factors that promote intercultural sensitivity
2012
The present study proposes a group of factors (related to self, context and process) favouring the development of intercultural sensitivity. A social diagnosis was performed in the Spanish province of Castellón in order to identify these factors by means of a correlational study. A non-probabilistic but representative sample consisting of 995 people from 37 different countries living in this province was used. Data were collected by means of an adaptation of the scale proposed by Chen and Starosta (2000) for the assessment of intercultural sensitivity. Results showed four profiles, and their main characteristics were studied. Variables such as country of origin, gender, academic background,…
