Diffusion on aluminum-cluster surfaces and the cluster growth
1998
Diffusion of adatoms have been studied on fcc polyhedral aluminum-cluster surfaces by molecular-dynamics simulations using the effective-medium theory. Diffusion of adatoms has been shown to take place by hopping along ${111}$ facets at very low temperatures. Diffusion from one ${111}$ facet to other ${111}$ facets takes place at higher temperatures through a variety of mechanisms, and finally diffusion to and along ${100}$ facets takes place at high temperatures. Diffusion from ${100}$ to ${111}$ facets is possible only close to the melting temperature of the cluster. The appearance of different diffusion processes as a function of temperature is in good agreement with the calculated activ…
Faceted Search Over RDF-Based Knowledge Graphs
2016
Knowledge graphs such as Yago and Freebase have become a powerful asset for enhancing search, and are being intensively used in both academia and industry. Many existing knowledge graphs are either available as Linked Open Data, or they can be exported as RDF datasets enhanced with background knowledge in the form of an OWL 2 ontology. Faceted search is the de facto approach for exploratory search in many online applications, and has been recently proposed as a suitable paradigm for querying RDF repositories. In this paper, we provide rigorous theoretical underpinnings for faceted search in the context of RDFbased knowledge graphs enhanced with OWL 2 ontologies. We identify well-defined fra…
Expressions multiplicatives en textos catalans medievals
2015
Explicitació i aclariment de passatges amb expressions multiplicatives en textos medievals en català: (1) "Estar en quatre tants" (Facet); (2) "A cent doblàries" (Vita Christi d'Isabel de Villena); (3) "Doble és l'afany" (poema 1 d'Ausiàs March). An explicitation and clarification of three medieval Catalan texts' passages with multiplicative expressions: (1) "Estar en quatre tants" (Facet); (2) "A cent doblàries" (Vita Christi by Isabel de Villena); (3) "Doble és l'afany" (Ausiàs March, poem 1).
The Relationship Between Attachment and Psychopathy: A Study with a Sample of Violent Offenders
2014
This study used a mixed quantitative-qualitative methodology to investigate the relationship between attachment and psychopathy. The Psychopathy Checklist- Revised (PCL-R; Hare 2003) was administered to 139 Italian offenders who were convicted of violent crimes (murder, rape, child sexual abuse, armed robbery, assault causing bodily harm). First, we explored whether the two PCL-R items theoretically denoting devaluation of attachment bonds (promiscuous sexual behavior and many marital relationships) were able to predict PCL-R total, factor and facet scores. Subse- quently, we analyzed the transcripts of the 10 participants who obtained the highest PCL-R scores in the sample, assessing their…
Access to autobiographical memory as an emotion regulation strategy and its relation to dispositional mindfulness
2016
Mindfulness research has extensively focused on mechanisms that make it work. Emotional regulation (ER) has been proposed as one of the mechanisms to explain the effects of mindfulness on health. ER is composed of a broad set of strategies, such as the use of autobiographical memory (AM), which refers to the recollection of personally experienced past events to regulate the emotion (i.e., remembering a positive past event in order to calm anxiety). Authors suggest that mindfulness and AM are related. However, few studies exist to explore this relationship that could promote a more adaptive ER. The aim of this study is to explore the relationship between the mindfulness trait and the use of …
