3D pointcloud processing using artificial intelligence and high performance computing techniques
No full textThis thesis studies 3D point cloud processing as a challenge for
computer science. High-performance computing techniques
and artificial intelligence models are explored as the main
strategies for efficiently processing 3D point clouds.
Some tasks approached in this thesis are terrain segmentation,
unsupervised clustering, analysis of crossing zones in urban
contexts, classification of curb points and their interpolation,
boundary segmentation, classical machine learning methods for
point-wise classification, deep-learning models for point-wise
classification and roughness estimation, and road bump
detection through surface fitting methods
Obtención, caracterización analítica y aplicación industrial de extractos bioactivos procedentes de los sectores agroalimentarios y acuícola
No full textEl agotamiento acelerado de los recursos naturales, unido al impacto generado en nuestro ecosistema por el uso de fuentes no renovables, genera reivindicaciones y reposicionamientos del sector industrial primario. El desarrollo sostenible de las actividades agroganaderas y acuícolas se muestra cómo alternativa de producción ética y responsable ante la abrasiva industria actual, y, en paralelo, las políticas en materia industrial imponen lógicos límites al malgasto de medios naturales. Este proyecto busca acercar soluciones a estos grandes desafíos sintetizados en la defensa de los recursos naturales mediante la valorización de los subproductos de actividades industriales específicas, como la implementación de fuentes alternativas de biomasa a partir de cultivos biotecnológicos.2025-06-2

mueve entre el branding city y el branding leadership, Vigo
aparece como un territorio especial para ver cómo estas
concepciones se encuentran. Los objetivos de la investigación
son analizar la formación y promoción de la imagen de la
ciudad y qué relación tiene esto con los enfoques del
marketing para su desarrollo. En otras palabras, vamos a
analizar los factores de desarrollo de la ciudad de Vigo, realizar
un estudio de la imagen interna y externa de Vigo entre los
residentes, aclarar el concepto de "marca de la ciudad" como
un componente del marketing territorial y desarrollar un

La colaboración entre los profesionales para el desarrollo educativo de niños y niñas con cáncer
No full textLa investigación consiste en un estudio exploratorio de carácter descriptivo para responder al objetivo de “Analizar la colaboración entre profesionales para proponer estrategias para una orientación educativa y profesional en niños con cáncer”. A través de la investigación indagamos en el sistema actual de coordinación que tienen los principales agentes en la atención educativa a niños enfermos de cáncer. Con los resultados obtenidos elaboramos una propuesta que permita mejorar la situación actual.
Para comprender la experiencia y la atención que reciben los menores con cáncer es necesario dar cuenta hoy en día de qué medidas se están desarrollando en la práctica. Para ello, nos hemos aproximado a esa realidad a través de un análisis documental sobre las políticas y los protocolos que se están aplicando desde las Administraciones Públicas como agente implicado, y a través del análisis de entrevistas a agentes que están en la realidad cotidiana en contacto con estos menores y que conocen las situaciones desde dentro
Enhancing patient outcomes: Integrating electronic cardiology consultation in primary care for cancer patients
Get PDFBackground: The prevalence of cancer patients with concomitant cardiovascular (CV) disease is on the rise due to improved cancer prognoses. The aim of this study is to evaluate the long-term outcomes of cancer patients referred to a cardiology department (CD) via primary care using e-consultation. Methods: We analysed data from cancer patients with prior referrals to a CD between 2010 and 2021 (n = 6889) and compared two care models: traditional in-person consultations and e-consultations. In e-consultation model, cardiologists reviewed electronic health records (e-consultation) to determine whether the demand could be addressed remotely or necessitated an in-person consultation. We used an interrupted time series regression model to assess outcomes during the two periods: (1) time to cardiology consultation, (2) rates of all-cause and CV related hospital admissions and (3) rates of all-cause and CV-related mortality within the first year after the initial consultation or e-consultation at the CD. Results: Introduction of e-consultation for cancer patients referred to cardiology care led to a 51.8% reduction (95%CI: 51.7%–51.9%) in waiting times. Furthermore, we observed decreased 1-year incidence rates, with incidence rate ratios (iRRs) [IC95%] of .75 [.73–.77] for CV-related hospitalizations, .43 [.42–.44] for all-cause hospitalizations, and .87 [.86–.88] for all-cause mortality. Conclusions: Compared to traditional in-person consultations, an outpatient care program incorporating e-consultation for cancer patients significantly reduced waiting times for cardiology care and demonstrated safety, associated with lower rates of hospital admissionsResearch grant from the Spanish Society of CardiologyS
Skeletal and Mechanistic Diversity in Ir‐Catalyzed Cycloisomerizations of Allene‐Tethered Pyrroles and Indoles
Get PDFPyrroles and indoles bearing N-allenyl tethers participate in a variety of iridium-catalyzed cycloisomerization processes initiated by a C−H activation step, to deliver a diversity of synthetically relevant azaheterocyclic products. By appropriate selection of the ancillary ligand and the substitution pattern of the allene, the reactions can diverge from simple intramolecular hydrocarbonations to tandem processes involving intriguing mechanistic issues. Accordingly, a wide range of heterocyclic structures ranging from dihydro-indolizines and pyridoindoles to tetrahydroindolizines, as well as cyclopropane-fused tetrahydroindolizines can be obtained. Moreover, by using chiral ligands, these cascade processes can be carried out in an enantioselective manner. DFT studies provide insights into the underlying mechanisms and justify the observed chemo- regio- and stereoselectivities.This work received financial support from Spanish grants (Grants PID2020-118579GB-I00 and PID2022-137318OB-I00 funded by MCIN/AEI, the ORFEO-CINQA network RED2022-134287-T and a predoctoral fellowship to A.

Evolution and characteristics of studies estimating attributable mortality to second-hand smoke: a systematic review
Get PDFBackground
Several studies have estimated the impact of second-hand smoke (SHS) exposure on mortality in the population of different countries. This study aimed to identify and describe studies that have estimated the attributable mortality (AM) associated with SHS exposure in the adult population.
Methods
A literature search was conducted in MEDLINE, EMBASE, Cochrane Library and CINAHL databases up to January 2023. Studies that estimated the AM associated with SHS exposure in the adult population and used a prevalence-dependent method were included. The main characteristics of the studies and their results were described.
Results
Fifty-three studies were included. Most of them were conducted in North America (n = 13), Europe (n = 14) and China (n = 6) and included lung cancer (n = 46) or ischaemic heart disease (n = 22) as causes of death. There was considerable variety in the population under study regarding the relationship with tobacco: non-smokers (n = 30); never-smokers (n = 9); both non and never-smokers (n = 2); the whole population (n = 1) and not known (n = 11). The age at which AM was estimated also varied between studies, ranging from 15 to 40 years and older.
Conclusions
Studies estimating AM associated with SHS exposure are heterogeneous in terms of the causes of death studied, the age at which mortality is attributed, or the population to which mortality referred: consensus should be reached. Despite their importance, studies assessing AM to SHS are infrequent in low- and middle-income countriesThis study has been funded by Instituto de Salud Carlos III (ISCIII) through the Project ‘PI22/00727’ and co-funded by the European Union and a SEPAR grant 2023 ‘Proposal 1426’S
