Modified mode-coupling theory for the collective dynamics of simple liquids
2011
Recently it has been shown that mode-coupling theory, which accounts for the salient features of glassy relaxation near the liquid–glass transition, is also capable of describing the collective excitations of simple liquids away from the glass transition. In order to further improve the agreement between theory and computer simulations on Lennard-Jones argon we modify MCT by taking binary collisions into account. This, in fact, improves the agreement. We also show that multiplying the memory function of the original theory with a reduction factor leads to similar results.
Bone Fusion in Normal and Pathological Development is Constrained by the Network Architecture of the Human Skull
2016
The premature fusion of cranial bones, craniosynostosis, affects the correct development of the skull producing morphological malformations in newborns. To assess the susceptibility of each craniofacial articulation to close prematurely, we used a network model of the skull to quantify the link reliability (an index based on stochastic block modeling and Bayesian inference) of each articulation. We show that, of the 93 human skull articulations at birth, the few articulations that are associated with nonsyndromic craniosynostosis conditions have statistically significant lower reliability scores than the others. In a similar way, articulations that close during the normal postnatal developm…
CREDIBILIDAD CORPORATIVA EN CADENAS TELEVISIVAS: ANTECEDENTES Y EFECTOS
2013
RESUMENLa creciente competencia está facilitando la aplicación del brand management en muchas industrias de medios, cuyos participantes necesitan establecer una credibilidad de marca clara y memorable. En este contexto, se ha planteado la presente investigación con información procedente de 816 valoraciones, a fin de de analizar los antecedentes capaces de explicar el desarrollo de una óptima credibilidad corporativa, así como sus efectos posteriores desde la perspectiva del consumidor. Para tal fin, han sido consideradas las cadenas televisivas de primera generación que operan en abierto en el territorio nacional (TVE 1, Antena 3, Tele 5, Cuatro y Sexta).ABSTRACTIncreasing competition is f…
Proteomic analysis highlights the role of detoxification pathways in increased tolerance to Huanglongbing disease.
2016
Background Huanglongbing (HLB) disease is still the greatest threat to citriculture worldwide. Although there is not any resistance source in the Citrus germplasm, a certain level of moderated tolerance is present. A large-scale analysis of proteomic responses of Citrus may help: 1) clarifying physiological and molecular effects of disease progression, 2) validating previous data at transcriptomic level, and 3) identifying biomarkers for development of early diagnostics, short-term therapeutics and long-term genetic resistance. Results In this work we have conducted a proteomic analysis of mature leaves of two Citrus genotypes with well-known differing tolerances to HLB: Navel orange (highl…
Dynamic architecture and regulatory implications of the miRNA network underlying the response to stress in melon
2019
miRNAs are small RNAs that regulate mRNAs at both transcriptional and posttranscriptional level. In plants, miRNAs are involved in the regulation of different processes including development and stress-response. Elucidating how stress-responsive miRNAs are regulated is key to understand the global response to stress but also to develop efficient biotechnological tools that could help to cope with stress. Here, we describe a computational approach based on sRNA sequencing, transcript quantification and degradome data to analyse the accumulation, function and structural organization of melon miRNAs reactivated under seven biotic and abiotic stress conditions at two and four days post-treatmen…

Education for democratic citizenship in a digital culture
2011
Asumiendo la importancia de las nuevas tecnologías en las aulas, especialmente en las actuales sociedades de la información y la comunicación, y siguiendo las recomendaciones de la Unión Europea a favor de la alfabetización mediática, el presente trabajo reflexiona acerca de la necesidad de educar no solo en los usos técnicos y eficientes de las tecnologías comunicativas, sino también en el uso responsable y cívico de las mismas, favoreciendo así los procesos participativos y deliberativos que son el sustento de una democracia viva. El sueño griego de la «isegoría», del igual derecho de todos al uso de la palabra, puede hacerse realidad en la cultura digital, si bien es cierto que un uso hi…
Asociaciones de inmigrantes, Estados y desarrollo entre España y Colombia. ¿Un nuevo campo social transnacional?
2017
A pesar de la distancia geografica, las asociaciones de inmigrantes colombianos en Espana han tenido una creciente incidencia en los asuntos locales de su pais de origen, y sus acciones han ido adquiriendo una progresiva dimension transnacional. Entre otras practicas, las asociaciones han implementado numerosos proyectos de desarrollo en Colombia que han implicado la movilizacion de redes verticales y horizontales, tanto en el pais de origen como en el de destino, en paralelo con el renovado interes de los Estados colombiano y espanol por dar soporte a esas acciones. En este articulo nos preguntamos en que medida estas dinamicas, inducidas por la migracion, podrian haber contribuido a la co…
Towards an integrated approach to emergency management: interdisciplinary challenges for research and practice
2015
This article presents an interdisciplinary vision for large-scale integrated emergency management that has been inspired by the transition from platform centric to integrated operations in the oil and gas fields, which uses remote emergency control centres collaborating virtually with local responders. The article discusses some of the most salient research challenges for integrated emergency management, including the role of mobile technology, human-centred sensing, citizen participation and social media, and the socio-cultural determinants of disaster management. The purpose of this article is to frame an integrated emergency management approach that adopts a multi-disciplinary approach, …
Tracing the Cultural Background of Lone-Wolf Terrorism
2021
The end of the Cold War, as well as the collapse of the Soviet Union, posed new greater challenges and risks for the “Global North.” Terrorism—doubtless—seems to be one of them. Over the recent years, and particularly after 9/11, terrorists changed the focus of their attacks. While classic terrorism targeted important persons such as politicians, chief police officers, or celebrities, modern terrorism planned attacks on leisure-spots spaces, tourist destinations, and lay-persons. This is particularly troublesome for policymakers (who are in charge of orchestrating all-pervading models to preserve homeland security) and for field-workers who are seriously punished when they are in contact wi…
