New stage-discharge relationship for cylindrical and semi-cylindrical edged sluice gates
2019
Abstract Gates are simple hydraulic structures which have been widely used for flow control and measurement in irrigation networks. In this paper new sluice gates with cylindrical and semi-cylindrical edges were introduced and the flow movement below these types of gates was experimentally investigated for both free- and submerged-flow conditions. The Buckingham theorem of dimensional analysis and the self-similarity theory were applied for developing the stage-discharge relationships for the two investigated flow conditions. For these cylindrical and semi-cylindrical edged gates and a free-flow condition, the proposed stage-discharge relationship was characterized by an estimate error less…
proTRAC - a software for probabilistic piRNA cluster detection, visualization and analysis
2012
Abstract Background Throughout the metazoan lineage, typically gonadal expressed Piwi proteins and their guiding piRNAs (~26-32nt in length) form a protective mechanism of RNA interference directed against the propagation of transposable elements (TEs). Most piRNAs are generated from genomic piRNA clusters. Annotation of experimentally obtained piRNAs from small RNA/cDNA-libraries and detection of genomic piRNA clusters are crucial for a thorough understanding of the still enigmatic piRNA pathway, especially in an evolutionary context. Currently, detection of piRNA clusters relies on bioinformatics rather than detection and sequencing of primary piRNA cluster transcripts and the stringency …
GSWABE: faster GPU-accelerated sequence alignment with optimal alignment retrieval for short DNA sequences
2014
In this paper, we present GSWABE, a graphics processing unit GPU-accelerated pairwise sequence alignment algorithm for a collection of short DNA sequences. This algorithm supports all-to-all pairwise global, semi-global and local alignment, and retrieves optimal alignments on Compute Unified Device Architecture CUDA-enabled GPUs. All of the three alignment types are based on dynamic programming and share almost the same computational pattern. Thus, we have investigated a general tile-based approach to facilitating fast alignment by deeply exploring the powerful compute capability of CUDA-enabled GPUs. The performance of GSWABE has been evaluated on a Kepler-based Tesla K40 GPU using a varie…
Virtual Reality as a Medium to Elicit Empathy: A Meta-Analysis.
2020
The current meta-analysis aims to investigate and clarify existing research on virtual reality (VR) as a medium to elicit empathy. An exhaustive literature search (updated to February 29, 2020) enabled us to locate seven published articles, yielding a total of nine independent samples. The results reveal statistically significant positive changes in perspective-taking outcomes after VR exposure (
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…
Social network loyalty: evaluating the role of attitude, perceived risk and satisfaction
2013
PurposeThe aim of this paper is to analyse the determinants of social networking site loyalty, paying special attention to the roles of user attitude, perceived risk and satisfaction.Design/methodology/approachThe impact of uses and gratifications of social networking sites, attitude, perceived risks and satisfaction on social networking site loyalty is tested through structural equation modelling techniques. The sample consisted of 811 Spanish social networking site users collected through a personal survey. Risk is measured as a formative construct.FindingsData analysis shows that attitude is a key variable in increasing satisfaction and loyalty towards social networking sites. Sociabilit…

La división digital en el proceso de integración de las NTIC en la educación. Diferencias de género entre alumnos de E.S.O. de la comunidad valenciana
2016
En este trabajo se analizan diferencias de género existentes en una muestra representativa de estudiantes de ESO de la Comunidad Valenciana en lo relativo a la integración de las TIC en el sistema educativo, desde una perspectiva univariada y multivariada. Estas diferencias se estudian en cuanto a disponibilidad y uso de Internet, formación, actitudes y valoración de sus repercusiones en la calidad de la educación. Los datos del estudio reflejan una cierta "brecha digital" favorable a los varones en lo concerniente a disponibilidad, uso y formación. Sin embargo, las actitudes de las chicas son aún más favorables a la integración de las TIC que las de los chicos, lo que induce a pensar que l…
Histoedu, social networks and history of education: pedagogical past from a present perspective
2016
This article presents some preliminary results and considerations about a R&D project about the use of ICTs and social media to do research on educational history. The progress achieved regarding the improvement of social and scientific communication, the significance of the learning process and the motivation shown by the academic community, make us point out the need to consolidate what we have been referring to as history of education 2.0. There are many chances available to learn and to build up knowledge in a shared way, and they challenge us to generate network knowledge and to cooperate in order to: spread our research, get to know other approaches to work, share resources and ex…
Italian and Spanish Students’ Perception on Use of Technology in Classrooms of Classics in Secondary School
2019
A society that is becoming increasingly digital must explore new ways of learning. In fact, digital technologies have an impact on the education through the development of more flexible learning environments adapted to the needs of a high-mobility society. To prepare future citizens to the needs of the digital labor market, recent educational reforms in Italy and Spain focused their attention on students’ Digital Competences. Therefore, we are interested in probing how students of classical studies in Italian and Spanish high schools perceive the use of new technologies in the classroom. It is important to investigate classics at school, because traditionally this program is perceived as le…
