Advanced Virgo Status
2015
Abstract The detection of a gravitational wave signal in September 2015 by LIGO interferometers, announced jointly by LIGO collaboration and Virgo collaboration in February 2016, opened a new era in Astrophysics and brought to the whole community a new way to look at - or “listen” to - the Universe. In this regard, the next big step was the joint observation with at least three detectors at the same time. This configuration provides a twofold benefit: it increases the signal-to-noise ratio of the events by means of triple coincidence and allows a narrower pinpointing of GW sources, and, in turn, the search for Electromagnetic counterparts to GW signals. Advanced Virgo (AdV) is the second ge…
Probing the electronic states of high-TMR off-stoichiometric Co2MnSi thin films by hard x-ray photoelectron spectroscopy
2014
The tunnel magnetoresistance ratio (TMR) of fully epitaxial magnetic tunnel junctions with an off-stoichiometric Co${}_{2}$MnSi Heusler alloy has been shown to exhibit a systematic dependence on Mn content, reaching 1135% at 4.2 K for Co${}_{2}$Mn${}_{1.29}$Si. In this paper, we explain the behavior of the observed TMR ratio using ab initio calculations and hard x-ray photoelectron spectroscopy (HAXPES). For the Mn-deficient samples, we show that the the drop of the TMR is caused by Co antisite atoms, which impose extra states into the minority-spin band gap. On the other hand, Mn-excess composition shows nearly half-metallic behavior. This result can be intuitively understood since both Co…
Una instantánea movida de la investigación en procesos de traducción
2014
This article offers an overview of some advances in cognitive and psycholinguistic approaches to translation and interpreting process research between 2006 and 2013, in order to provide context to the contributions to this volume. It provides some figures on publications and initiatives and then focuses on competence and expertise; writing; mental load and linguistic complexity; advances in research methods; revision and metacognition; cognition beyond conscious, rational thought; and recontextualized empirical research. The article closes with some notes on the overall tendencies in the area, in the sample of contributions, and in publishing.
Dynamics in the Magnetospheres of Compact Objects
2020
Esta tesis doctoral explora el modelado de la dinámica en las magnetosferas alrededor de objetos compactos (agujeros negros y estrellas de neutrones), y sus implicaciones en la formación de fenómenos de alta energía como las llamaradas en magnetares y la emisión de alta variabilidad en el rango de los teraelectronvoltios (TeV) de algunos núcleos galácticos activos, por medio de simulaciones numéricas. Las sorprendentes imágenes de las sombras de los agujeros negros (BH) del centro galáctico y la galaxia M87 proporcionan una primera visión directa de la física de los flujos de acreción en los entornos más extremos del universo. La extracción eficiente de energía en forma de flujos de plasma …

Trigger and aperture of the surface detector array of the Pierre Auger Observatory
2010
The surface detector array of the Pierre Auger Observatory consists of 1600 water-Cherenkov detectors, for the study of extensive airshowers (EAS) generated by ultra-high-energy cosmic rays. We describe the trigger hierarchy, from the identification of candidates howers at the level of a single detector, amongst a large background (mainly random single cosmic ray muons), up to the selection of real events and the rejection of random coincidences. Such trigger makes the surface detector array fully efficient for the detection of EAS with energy above 3 x 1018 eV, for all zenith angles between 03 and 603, independently of the position of the impact point and of the mass of the primary particl…
Le sfide della formazione urbanistica nell’era post-pandemia
2022
La diffusione dell’infezione da Sars-CoV2 e la crisi di sistema, che ne è conseguita, hanno generato una serie di impatti che vanno ben oltre il campo dell’epidemiologia investendo anche l’ambito della formazione accademica dei futuri pianificatori sotto il profilo sia dei contenuti che delle metodologie didattiche. L’articolo restituisce una riflessione critica sull’impatto della pandemia da Covid-19 sull’insegnamento del planning a partire dalle esperienze didattiche condotte dall’autore presso il Corso di laurea magistrale in Pianificazione territoriale urbanistica e ambientale dell’Università degli Studi di Palermo. Un’occasione per avviare un ragionamento più ampio non solo sulle compe…
Olive oil intake and cancer risk: A systematic review and meta-analysis
2022
Background Research evidence has established the beneficial effects of diet in cancer prevention; various epidemiological studies have suggested that olive oil component could play a role in decreasing cancer risk. This systematic review and meta-analysis aims to investigate the association between olive oil consumption, cancer risk and prognosis. Methods A systematic search was conducted in PubMed, EMBASE and Google Scholar databases (end-of-search: May 10, 2020). Pooled relative risk (RR) and 95% confidence intervals (95% CIs) were estimated with random-effects (DerSimonian-Laird) models. Subgroup analyses, sensitivity analyses and meta-regression analysis were also performed. Results 45…
Dilemmaer i skandinavisk korlederutdanning
2021
Within higher education, programmes in choral conducting are offered of varying kinds and at different levels, from dedicated programmes to single courses that are embedded in other music programmes. The choral practice field is varied; choral leadership is partly a generic music competence and partly a profession. The variety and social reach of the choral movement suggest that the educational offering in choral conducting should be manifold in type and quantity in order to supply the practice field with qualified conductors. n this chapter we take a renewed look at material from three previous studies: (1) a mapping of Scandinavian choral leader education, based on document analysis and i…
