    Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Curs: 2023, Tutora: Aida Niñerola BaizanThis project aims to evaluate deep learning algorithms’ suitability to correctly delineate the regions of interest on computer tomography images for dosimetric computations, in the context of postoperative endometrial carcinoma treatment. To achieve this goal, the project includes the complete training and evaluation of two deep learning networks. Furthermore, a qualitative assessment of the predicted dosimetric computations and a post-processing of the predicted results have been conducte

    Role of k-point sampling in the supercell approach to inelastic electron tunneling spectroscopy simulations of molecular monolayers

    Under the terms of the Creative Commons Attribution License 3.0 (CC-BY).While the role of sampling of the electron momentum k in supercell calculations of the elastic electron transmission is well understood, its influence in the case of inelastic electron tunneling (IET) has not yet been systematically explored. Here we compare ab initio IET spectra of molecular monolayers in the commonly used Γ-point approximation to rigorously k-converged results. We study four idealized molecular junctions with either alkanedithiolates or benzenedithiolates, and explore variations due to varying molecular tilt angle, density, as well as chemical identity of the monolayer. We show that the Γ-point approximation is reasonable for a range of systems, but that a rigorous convergence is needed for accurate signal amplitudes. We also describe an approximative scheme which reduces the computational cost of the k-averaged calculation in our implementation.We acknowledge the support of the Basque Departamento de Educacion and the UPV/EHU (Grant No. IT-756-13), the Spanish Ministerio de Economía y Competitividad (MINECO Grants No. MAT2013-46593-C6-2-P and FIS2013-48286-C2-2-P), and the European Union Integrated Project PAMS (Contract No. 610446).Peer Reviewe

    El artículo describe y analiza tres acuarelas del arquitecto valenciano Manuel Cortina (1868-1950) tituladas Iglesia Parroquial, Casa de Recreo en una posesión de caza y Fuente Monumental. Anota, como antecedentes-consecuentes respectivos, los dibujos de E. E. Viollet-le-Duc, C. N. Ledoux y O. Wagner. Y discurre acerca de este procedimiento pictórico, transparente y distante, como emblema de un tiempo, la belle époque, y un estilo, la Sezession vienesa alrededor de 1900, con alusión a sus relaciones fotográficas, cinematográficas y oníricas.This paper describes and analyzes three watercolors by the Valencian architect Manuel Cortina (1868-1950) titled Iglesia Parroquial (Parish Church) Casa de Recreo en una posesión de caza. (Country house in a private hunting preserve) and Fuente Monumental. (Monumental Fountain), focusing on the influence of C. N. Ledoux, O. Wagner and E. E. Viollet-le-Duc¿s drawings on Cortina¿s paintings. The paper also describes this transparent and distant painting method as emblematic of a period, the Belle Époque, and a movement, the Vienna Sezession of the late 19th century, and its photographic, cinematographic and oneiric imagery.Arnau Amo, J.; Gutiérrez Mozo, E.; Martínez Medina, A.

    4 páginas, 3 figuras, 1 tabla.-- PACS numbers: 68.37.Ef, 72.10.-d, 72.25.-b, 79.20.RfDensity functional theory simulations of the vibrational inelastic electron tunneling spectroscopy (IETS) of O2 on Ag(110) permits us to solve its unexplained IETS data [ Hahn et al. Phys. Rev. Lett. 85 1914 (2000)]. When semilocal density functional theory is corrected by including static intra-atomic correlations, the IETS simulations are in excellent agreement with the experiment. The unforeseen consequence of our calculations is that when adsorbed along the [001] direction, molecular O2 on Ag(110) is a mixed-valent system. This analysis of IETS unambiguously reveals the paramagnetic nature of O2 on Ag(110).We acknowledge financial support from the Spanish MICINN (No. FIS2007-066711-CO2-00 and No. FIS2009-12721-C04-01), and the Basque Government—UPV/EHU (Grant No. IT-366-07).Peer reviewe

    Este artículo presenta parte de los resultados de una investigación más amplia llevada a cabo en el seno de una comunidad inmigrante marroquí en territorio español. El objetivo de la investigación es conocer aquellos procesos de aprendizaje que generan oportunidades para la integración de este colectivo en la sociedad de acogida, así como las relaciones de dominación que se manifiestan en el proceso desde el Estado hacia la comunidad. Las bases teóricas de las que parte la investigación son el concepto de dominación, a partir esencialmente de la obra de Pierre Bourdieu, y el de aprendizaje situado propuesto por Jane Lave y Étienne Wenger. La investigación se llevó a cabo desde un enfoque cualitativo basado en la pluralidad metodológica en la que se encontraban tanto los estudios de caso, como la etnografía y también la investigación biográfico-narrativa. Las herramientas para la producción de la información son entrevistas en profundidad de carácter biográfico-narrativo, grupos de discusión y diario de campo. El análisis de los datos partió de un proceso de codificación axial. Los resultados de la investigación se concretan en el relato del periplo que han seguido los miembros de esta comunidad desde su llegada a territorio español, destacando el tiempo que tuvieron que pasar en la clandestinidad, así como el proceso seguido para regularizar su situación en España. En estos procesos, se manifiesta como determinante la colaboración de la toda la comunidad. Por último, en la discusión y conclusiones, proponemos que nos encontramos ante un proceso de aprendizaje situado en el que los marroquíes empiezan siendo participantes periféricos legítimos, caracterizado por una relación de dominación dese el Estado que acaba generando transformaciones en la identidad de los marroquíes hacia la subalternidad y la extranjeridad.This paper presents a portion of the results of a broader investigation carried out within a Moroccan immigrant community in Spanish territory. The aim of the research is to discover which learning processes generate integration opportunities for this collective in the host society, as well as the relations of domination that appear in the process. The theoretical bases are the concepts of domination, based essentially on the work of Pierre Bourdieu, and situated learning, as proposed by Lave and Wenger. The research was conducted through a qualitative approach based on the methodological plurality using case studies, ethnography and biographical-narrative research. In-depth biographical-narrative interviews, discussion groups and field diaries were used to collect data. The results of the research are expressed in the story of the journey that the members of this community have followed since their arrival in Spanish territory, emphasising the time they had to spend in hiding, as well as the process followed to regularise their situation in Spain and continue to live in this country; in these processes, the collaboration of the whole community is decisive. Finally, in the discussion and conclusions, we propose a situated learning process in which Moroccan citizens begin as legitimate peripheral participants. It is a process characterised by a domination relationship by the state that ends up generating transformations in the identity of Moroccan nationals, resulting in a situation of subalternity and foreignness
