Coronary artery calcium score on low-dose computed tomography for lung cancer screening
2013
Aim: To evaluate the feasibility of coronary artery calcium score (CACS) on low-dose non-gated chest CT (ngCCT). Methods: Sixty consecutive individuals (30 males; 73 ± 7 years) scheduled for risk stratification by means of unenhanced ECG-triggered cardiac computed tomography (gCCT) underwent additional unenhanced ngCCT. All CT scans were performed on a 64-slice CT scanner (Somatom Sensation 64 Cardiac, Siemens, Germany). CACS was calculated using conventional methods/scores (Volume, Mass, Agatston) as previously described in literature. The CACS value obtained were compared. The Mayo Clinic classification was used to stratify cardiovascular risk based on Agatston CACS. Differences and corre…
Validating Test Score Interpretations by Cross-National Comparison
2015
Cross-national assessment of students’ competences in higher education is becoming increasingly important in many disciplines including economics but there are few available instruments that meet psychological standards for assessing students’ economic competence in higher education (HE). One of them is the internationally valid Test of Understanding in College Economics (TUCE), which has been adapted and employed successfully in HE systems in various countries, but the test results have seldom been used for international comparisons of students’ Economic Content Knowledge (ECK). Here, we compare the German and the Japanese test adaptations of the TUCE with reference to the American origin…
Joan Roís de Corella, la seua vida i el seu entorn: noves dades per a la història de la cultura en la València del segle xv
2014
This article offers a full updating of the biographical records of the writer Joan Roís de Corella (1435-1497) and his family: his great-grandparents, grandparents, parents, siblings and children. All data are presented in a systematic way, generation by generation, and a new vision of the writer himself is offered. In its documentary section, 432 documents are transcribed or summarised, dating from 1373 to 1516. A broad range of new archival data is presented; other previously known data are corrected or improved. Some examples: Joan Roís de Corella had four children: Magdalena (born 1459), Maria, Joan and Estefania, the latter two by Isabel Martínez de Vera. Joan Roís de Corella was widel…
Quantitative methods in business history: An impossible equation?
2010
Abstract In this article we want to evaluate how often quantitative tools and methods were utilized in the two premier journals in business history in the 1990s. Thus we tap into an important methodological discussion among the post-Chandlerian business historians. We found that simpler quantitative tools were employed quite often, but not necessarily going much beyond that.Also, it became apparent that the most cited business history articles were often written by scholars coming from‘outside’ the fluid disciplinary core of business history field.The analyses performed in the article revealed that the level of quantification seemed to have either no discernible impact (Business History Rev…
Railroad integration and uneven development on the European periphery, 1870-1910
2021
This study explores the relationship between railroad integration and regional development on the European periphery between 1870 and 1910, based on a regional dataset including 291 spatial units. Railroad integration is proxied by railroad density, while per capita GDP is used as an indicator of economic development. The period under study is of particular relevance as it has been associated with the second wave of railroad construction in Europe and also coincides with the industrialization of most of the continent. Overall, we found that railroads had a significant and positive impact on the growth of per capita GDP across Europe. The magnitude of this relationship appears to be relative…
Supercontinuum generation in Ge-doped Y-shaped microstructured tapered fiber
2011
We have investigated the generation of supercontinuum in tapered Y-shaped fibers in the nanosecond pump regime. This fiber used to fabricate the tapers has, in addition, a Ge-doped core which enhances the nonlinearity of the material and the Raman gain. The fiber was pumped at 1064 nm in the ns pump regime (0.6 ns pulses and up to 3.2 kW peak power). The taper had a uniform waist of 0.9 μm diameter and 130 mm length, and the adiabatic transitions were 110 mm long. A flat spectrum spanning from 420 nm to 1870 nm was obtained using a single tapered fiber.
Millimeter wave absorption by confined acoustic modes in CdSe/CdTe core-shell quantum dots
2007
International audience; Taking advantage of the specific core-shell charge separation structure in the CdSe/CdTe core-shell Type-II quantum dots (QDs), we experimentally observed the resonant-enhanced dipolar interaction between millimeter-wave (MMW) photons and their corresponding (l = 1) confined acoustic phonons. With proper choice of size, the absorption band can be tuned to desired frequency of MMW imaging. Exploiting this characteristic absorption, in a fiber-scanned MMW imaging system, we demonstrated the feasibility of CdSe/CdTe QDs as the contrast agents of MMW imaging.
Joan Roís de Corella, Lamentació de Mirra, de Narciso, de Píramus i Tisbe: edizione critica
2016
Il contributo, che è un’anticipazione parziale dell’edizione critica integrale delle narrazioni mitologiche di Joan Roís de Corella (XV sec.) per Barcino (ENC), nasce dall’esigenza di rivedere la situazione testuale della faula in oggetto (Lamentació de Mirra, de Narciso, de Píramus i Tisbe) e di avanzare, dove necessario, nuove proposte di lettura. Esso consta di due parti, delle quali la prima contiene l’Introduzione, la seconda il Testo con note a piè di pagina, in cui si discutono questioni relative alla constitutio textus, l’Apparato e l’Apparato complementare. Nell’Introduzione si danno informazioni essenziali circa la tradizione manoscritta delle Lamentacions (altrimenti note come Lo…
La poesia en la prosa de Joan Roís de Corella : delimitació i transmissió del corpus
2019
Resum: L’obra en prosa de Joan Roís de Corella es caracteritza per incorporar-hi poesies. En aquest sentit, aquest treball té un doble objectiu, que es marca des del seu títol: d’una banda, delimita el corpus, que arriba a catalogar vint-i-un poemes, d’una extensió molt diversa, des d’un sol vers fins a vint-i-vuit; d’una altra banda, estudia la transmissió textual d’aquests poemes, amb especial atenció als trets que caracteritzen els diferents testimonis i a les particularitats de transmissió dels poemes.Paraules clau: Joan Roís de Corella, poesia, transmissió textual, corpus, codicologia.Abstract: The work in prose by Joan Roís de Corella is characterized by the incorporation of poetry.

Amores humanos, amores divinos. La Vita Christi de sor Isabel de Villena
2014
La Vita Christi de Sor Isabel de Villena es un texto de enorme relevancia escrito en la Edad Media. Basado en la Vita Christi de Ludolfo de Sajonia, el Cartujano, puede en realidad interpretarse como una Vita Mariae, pues en él se presta atención particular al papel de la Virgen en la vida de Cristo. Este artículo analiza los paralelos entre esta obra y las prosas mitológicas de Joan Roís de Corella. En los dos puede verse un interés en temas amorosos y en la descripción de los afectos y el mundo interior emocional de los personajes. The Vita Christi by Sor Isabel de Villena is a paramount text written in medieval Iberia. Based on the Vita Christi by Ludolf of Saxony (the Carthusian), the w…
