COVID-19 Contact Tracing and Data Protection Can Go Together
2020
We discuss the implementation of app-based contact tracing to control the coronavirus disease (COVID-19) pandemic and discuss its data protection and user acceptability aspects.
Speech Perception: Phonological Neighborhood Effects on Word Recognition Persist Despite Semantic Sentence Context
2019
This study tested the hypothesis that two lexical properties, both phonological neighborhood density (ND) and neighborhood frequency (NF), influence the recognition of target words when preceded by either a semantically congruent or semantically neutral context. Our study is the first to test this hypothesis using a language other than English (i.e., Spanish). We used highly familiar bisyllabic nouns with medium-frequency occurrence as target words, and we expected recognition accuracy to increase as ND and NF decreased in both semanticallly congruent and semantically neutral sentences. We presented 48 undergraduate listeners with a set of 80 words, differing in ND and NF, within these two…
Fibroblast Growth Factor Receptor 1– 5-Hydroxytryptamine 1A Heteroreceptor Complexes and Their Enhancement of Hippocampal Plasticity
2011
Background The hippocampus and its 5-hydroxytryptamine transmission plays an important role in depression related to its involvement in limbic circuit plasticity. Methods The analysis was made with bioluminescence resonance energy transfer, co-immunoprecipitation, in situ proximity ligation assay, binding assay, in cell western and the forced swim test. Results Using bioluminescence resonance energy transfer analysis, fibroblast growth factor receptor 1 (FGFR1)-5-hydroxytryptamine 1A (5-HT1A) receptor complexes have been demonstrated and their specificity and agonist modulation characterized. Their presence based on co-immunoprecipitation and proximity ligation assay has also been indicated…
Tra spazi e funzioni. La crisi dello spazio urbano prima, durante e dopo il Covid-19
2022
Fin dagli albori dell'età urbana, i problemi e i valori dell'insediamento urbano sono variati notevolmente nel corso dei secoli, ma l'importanza della struttura spaziale urbana non è mai stata cancellata. Oggi la città è ancora al centro della nostra civiltà, ma le relazioni tra sistemi socio-ecologici nidificati sono più complesse perché le interazioni uomo-ambiente non sono bidirezionali. L'ascesa dell'Antropocene, una nuova era dirompente ed erosiva causata dall'Umanità, comporta una crisi economica, demografica e ambientale, come dimostrano le attuali pandemie. Il mese scorso le notizie ci hanno detto che il nuovo coronavirus non è stato il primo caso di virus che salta la specie, raggi…
Best approximation and variational inequality problems involving a simulation function
2016
We prove the existence of a g-best proximity point for a pair of mappings, by using suitable hypotheses on a metric space. Moreover, we establish some convergence results for a variational inequality problem, by using the variational characterization of metric projections in a real Hilbert space. Our results are applicable to classical problems of optimization theory.
Introduction. A nagging thought of a scholar
2019
This paper is – as introduction of volume “Proximity violence in migration times” – is the result of the nagging thought of a scholar and the support the European Commission decided to provide her with in order to favour the theoretical challenge the project envisaged and allowing her to conduct these two years of research supported by a network of partners comprising universities, research centres and non-profit organisations. It is the product of a combined, reasoned in-the-field research and desk analysis regarding recognition and reception of refugee-asylum seekers, victims of violence within their places of origin, during the journey to the European states bordering on the Mediterranea…
Organizational information and communication technologies and their influence on communication visibility and perceived proximity
2021
This study investigates the relationships between the use of various organizational ICTs, communication visibility, and perceived proximity to distant colleagues. In addition, this study examines the interplay between visibility and proximity, to determine whether visibility improves proximity, or vice versa. These relationships are tested in a global company using two waves of panel survey data. ESM use increases communication visibility and perceived proximity, while controlling for prior levels of visibility, proximity, and the use of other organizational ICTs. The influence of ESM on network translucence and perceived proximity is generally stronger than the impact of other technologie…
XPO1E571K Mutation Modifies Exportin 1 Localisation and Interactome in B-cell Lymphoma
2020
The XPO1 gene encodes exportin 1 (XPO1) that controls the nuclear export of cargo proteins and RNAs. Almost 25% of primary mediastinal B-cell lymphoma (PMBL) and classical Hodgkin lymphoma (cHL) cases harboured a recurrent XPO1 point mutation (NM_003400, chr2:g61718472C>

Association between residential proximity to environmental pollution sources and childhood renal tumors
2016
FI=3.835 (año 2016), Q1 Background: Few risk factors for childhood renal tumors are well established. While a small fraction of cases might be attributable to susceptibility genes and congenital anomalies, the role of environmental factors needs to be assessed. Objectives: To explore the possible association between residential proximity to environmental pollution sources (industrial and urban areas, and agricultural crops) and childhood renal cancer, taking into account industrial groups and toxic substances released. Methods: We conducted a population-based case-control study of childhood renal cancer in Spain, including 213 incident cases gathered from the Spanish Registry of Childhood T…
