Computer-aided detection of cerebral microbleeds in susceptibility-weighted imaging.
2014
Susceptibility-weighted imaging (SWI) is recognized as the preferred MRI technique for visualizing cerebral vasculature and related pathologies such as cerebral microbleeds (CMBs). Manual identification of CMBs is time-consuming, has limited reliability and reproducibility, and is prone to misinterpretation. In this paper, a novel computer-aided microbleed detection technique based on machine learning is presented: First, spherical-like objects (potential CMB candidates) with their corresponding bounding boxes were detected using a novel multi-scale Laplacian of Gaussian technique. A set of robust 3-dimensional Radon- and Hessian-based shape descriptors within each bounding box were then ex…
Considerations Regarding the Analysis and Interpretation of Traumatic Lesional Mechanisms in Road Accidents
2021
According to statistics, road transportation is the most dangerous means of transportation and also the costliest in terms of human lives and material damage. The increase of road safety is a priority goal of the European Commission and an area of high interest for Romania, which is unfortunately placed very high in the hierarchy of countries with a high number of deaths resulting from road accidents. This study presents the mechanisms of the generation of traumatic injuries and also analyses the manner of interpreting these mechanisms in the case of road accidents, both from the perspective of law enforcement and from the perspective of specialists in road transportation, who analyse and i…
Fomento del Mobile Learning en educación alrededor de la última década. Un estudio de caso en españa través de una selección de aportaciones.
2020
En la actualidad educativa las TIC han propiciado de manera inevitable el uso de los dispositivos móviles en el aula y en concreto del teléfono móvil como herramienta educativa. Desde hace años se desarrolla literatura al respecto y se han llevado a cabo proyectos y actividades educativas que lo promocionan. Se trata de una de las metodologías educativas emergentes que ha ido en aumento paulatinamente, se va integrando en la escuela tímidamente y, en algunos casos, con ciertos prejuicios sobre su uso. El siguiente escrito aborda el desarrollo del Mobile Learningo Aprendizaje en Movilidad en la segunda década del siglo XXI en el Estado Español. Damos cuenta de la divulgación científica acont…
pruebas de acceso a enseñanzas superiores de música en España
2021
El profesorado del último ciclo de Enseñanzas Profesionales de Clarinete debe preparara al alumnado para superar la Prueba de Acceso a Enseñanza Superior, sin dejar por ello de cumplir con las exigencias específicas de la etapa correspondiente. Profesorado y alumnado se enfrentan a dificultades que pueden surgir por la complejidad del repertorio, por complicaciones técnicas derivadas del mismo o por cuestiones de índole psicológica ante la interpretación pública. Las opiniones al respecto de los agentes implicados son variadas y llevan, en muchos casos, a estigmatizar todavía más dichas pruebas. En este documento, se recogen las diferentes consideraciones sobre las Pruebas de Acceso por par…
Joan Crawford: creación de la working girl y continuidad de la “Fórmula Crawford”
2008
Afirmar que Joan Crawford interpretó durante toda su carrera cinematográfica un único papel, no sólo es altamente arriesgado, sino fácilmente discutible. Ahora bien, a comienzos de la década de 1930 y específicamente con su película Possessed (Amor en venta, 1931), de Clarence Brown, tuvo lugar la creación de un personaje fílmico que la actriz repetiría posteriormente de modo continuado a lo largo de los años sobrepasando Mildred Pierce (Alma en suplicio, 1945), de Michael Curtiz. Este personaje es el de la working girl (chica trabajadora). La creación resultó tan eficaz que se potenció y utilizó al máximo en muchos de los films que Joan Crawford realizó en la década de los 30, y cuando la …
The Bua Group noun class system: Looking for a historical interpretation
2020
International audience; The way Bua languages express number on nouns mostly consists ofalternating suffi xes that bear witness of a former classifi cation system. However,Kulaal is the only present-day language where these markers are not frozen butactually trigger agreement with free, optional determiners that follow the noun andmay show some formal affi nity with its suffi x. For several reasons, previous attemptsat reconstructing a historical noun morphology common to all Bua languagesconsidered the sole suffi xes and neglected the determiners present in Kulaal. But,as is argued in the present paper, more recent data show that, in some cases, presentdaysuffi xes may result from the asso…
A viagem, ou as ilusões da comunicação
2017
Na França, e para além dela, viajar se tornou atualmente objeto de tamanho interesse que a viagem já não se trata mais de um fenômeno da moda, mas constitui um dos elementos fundamentais do comportamento contemporâneo. As razões levantadas pelos incontáveis nômades ocasionais pertencem ao registro da comunicação: ir ao encontro do Outro, dizem eles, responde a uma grande preocupação com a cultura e a humanização. Esta visão reconfortante pode e deve nos satisfazer? Em uma célebre diatribe, o antropólogo Claude Levi-Strauss criticou esta grande obsessão com a transumância. O filósofo Jean Brun, por sua vez, desenvolveu uma interpretação particularmente redutora sobre os vagabundos do Ocident…
Die Embryologie im Spannungsfeld zwischen Tradition und Empirie.
1991
Already in classical antiquity people dealt with the principle of formation, developing different theories. Researchers in the renaissance, working in the conflict zone between tradition and experience, tried to prove one or the other of these theories by the means of new observations, especially of chicken development. Aldrovandi was the first to see the real principle of formation of the hen's egg, i. e. the blastodisc, but he didn't recognize the importance of his discovery due to his close adherence to Aristotle in the theoretical field. Fabricius even thought that traditional knowledge was of more importance than his own excellent observations. Parisano was the first to succeed in maki…
Rationalitäten der Wissenproduktion: Über Transformationen von Gegenständen, Technologien und Information in Biomedizin und Lebenswissenschaften
2009
Rationalities of Knowledge Production: On Transformations of Objects, Technologies and Information in Biomedicine and the Life Sciences. Since decades, scientific change has been interpreted in the light of of paradigm shifts and scientific revolutions. The Kuhnian interpretation of scientific change however is now more and more confronted with non-disciplinary thinking in both, science and studies on science. This paper explores how research in biomedicine and the life sciences can be characterized by different rationalities, sometimes converging, sometimes contradictory, all present at the same time with varying ways of influence, impact, and visibility. In general, the rationality of obj…
Interpretation of EXAFS in scheelite-type AWO4(A = Ca, Sr, Ba) compounds using molecular dynamics simulations
2013
In this work we successfully interpret the W L3-edge EXAFS spectra in scheelite-type AWO4 (A = Ca, Sr, Ba) compounds using a combination of classical NVT molecular dynamics (MD) and ab initio multiple-scattering (MS) theory. The configuration-averaged EXAFS spectra show good agreement with our room temperature experimental data supporting the reliability of the developed force-field models. The contributions from all coordination shells up to 6 A are elucidated. The contribution of the MS effects into the total EXAFS signal in AWO4 compounds is small, being around 10%.
