Estudio prospectivo para evaluar el papel de la valoración geriátrica en pacientes con carcinoma no microcítico de pulmón estadio III irresecable
No full textLa quimiorradioterapia concurrente es el tratamiento estándar para el cáncer de pulmón de células no pequeñas localmente avanzado irresecable. La valoración geriátrica permite seleccionar pacientes aptos para tratamiento activo y detectar aquellos vulnerables o frágiles que requieren cuidados paliativos o intervenciones específicas. Este estudio prospectivo exploratorio incluyó pacientes ≥ 70 años sometidos a valoración geriátrica. Los objetivos secundarios fueron describir la población, evaluar la valoración geriátrica como factor pronóstico, determinar el perfil de toxicidad y explorar un biomarcador de fragilidad. Se incluyeron 51 pacientes; el 35% fueron clasificados como frágiles, presentando menor supervivencia global y mayor toxicidad severa. Los resultados confirman que la valoración geriátrica puede identificar pacientes frágiles no aptos para tratamiento activo, con mayor riesgo de toxicidad. Los resultados de los análisis de sangre sugieren la posibilidad de nuevas hipótesis sobre biomarcadores de fragilidad.Concurrent chemoradiotherapy is the standard approach for locally advanced, unresectable non-small cell lung cancer (NSCLC). As the cancer population increasingly consists of older adults, the role of Geriatric Assessment (GA) in identifying patients suitable for intensive treatment becomes relevant. Although GA has demonstrated value in multiple tumor types, its application in advanced unresectable NSCLC remains limited. This prospective, non-interventional exploratory study evaluated the ability of GA to identify frail patients who may not benefit from active treatment. Patients aged ≥70 years with unresectable locally advanced NSCLC underwent GA. Secondary objectives included population characterization, assessment of the prognostic value of GA, toxicity evaluation, and exploration of potential frailty biomarkers. Between June 2017 and June 2020, 51 patients were enrolled; 35% were classified as frail. Frailty was associated with reduced overall survival and higher grade 3–4 toxicities. Findings suggest that GA effectively identifies older patients unsuitable for intensive treatment and highlights potential biological markers warranting further investigation.Programa de Doctorat en Ciències Biomèdiques i Salu

Depth Error and Noise Analysis in Multi-frequency Indirect Time-of-Flight Imaging
No full textCompendi d'articles, Doctorat industrialThis PhD thesis investigates the fundamental limitations and performance factors of indirect Time-of-Flight (iToF) camera systems, with a focus on improving phase estimation accuracy and depth reliability. The global objective is to enhance the understanding of error sources in iToF systems and to develop models and methodologies that improve their robustness and precision in both academic and industrial contexts. The research is structured around three main contributions. First, a multi-objective optimization framework is proposed for selecting modulation frequencies in multi-frequency iToF systems. This model simultaneously minimizes phase unwrapping errors and maximizes depth precision, while incorporating constraints such as maximum unambiguous range and frequency limits, adapting to specific application requirements. Thanks to this multi-objective formulation, the proposed optimization model improves the performance over existing methods. Second, the thesis presents a generalized shot noise model for traditional sampling architectures. This model accounts for key system parameters including modulation frequency, signal amplitude, background illumination, integration time and the number of points in the Discrete Fourier Transform. It provides a deeper understanding of noise behaviour. A second order-order error propagation is modelled to get a more accurate phase variance estimation. Third, the analysis is extended to the differential sampling architecture used in commercial sensors, such as those developed by Analog Devices Inc (ADI). This architecture simplifies the analog front-end and removes the DC component of the received light, optimizing the use of the dynamic range of the Analog to Digital Converter. A new shot noise model is derived, showing that phase error is inversely proportional to signal amplitude and directly proportional to background illumination, while remaining independent of the number of points in the Discrete Fourier Transform. Together, these contributions form a unified framework that links frequency design and noise modelling, offering practical tools for optimizing iToF systems. The proposed methodologies have been validated through extensive simulations and experimental data, and have been integrated into the development of next-generation iToF modules at ADI. This work lays the foundation for future research in adaptive frequency selection strategies and enhanced noise mitigation, particularly in environments affected by multipath interference and dynamic scene conditions.Programa de Doctorat en Informàtic
La comunicación del propósito corporativo en organizaciones con impacto positivo. Sinergias y comparaciones entre las prácticas de las B Corporations y de las ONG.
No full textSe analiza cómo el propósito corporativo transforma organizaciones con impacto positivo, especialmente B Corporations y ONG. Se demuestra que, a diferencia de la responsabilidad social tradicional, el propósito actúa como una brújula estratégica que guía decisiones, cultura y comunicación. A través de un enfoque comparativo, se evidencian diferencias: mientras las B Corporations integran el propósito desde su modelo de negocio, muchas ONG lo entienden como misión, aunque sin herramientas estratégicas o comunicativas suficientes para hacerlo visible. La coherencia entre lo que se dice y lo que se hace emerge como clave para la confianza pública. Se identifican oportunidades de colaboración entre ambos sectores, y se proponen recomendaciones para que las ONG fortalezcan su propósito, modernicen su comunicación y refuercen su singularidad. La tesis plantea que hablar de “propósito social” puede ayudar a las ONG a diferenciarse y conectar mejor con las nuevas generaciones, promoviendo un impacto más amplio y sostenibleThis doctoral thesis examines how corporate purpose is integrated and communicated within organizations with a positive impact, focusing on B Corporations and non-governmental organizations (NGOs). In a context where companies are called to act as agents of social change, corporate purpose emerges as an evolution of corporate social responsibility and as a strategic axis of corporate communication. Through a qualitative research design structured in four phases (content analysis, horizontal comparison, expert interviews, and triangulation) the study explores the differences and synergies between both organizational models. The findings reveal that while B Corporations are founded with an activated purpose, NGOs face challenges in updating their communication strategies. The research concludes that purpose only generates impact when it is activated, coherently communicated, and connected to action, proposing a framework to enhance the integration and communication of purpose in organizations operating with limited resources.Programa de Doctorat en Ciències de la Comunicaci

Literatura intercultural y traducción: expresiones fraseológicas y metafóricas en obras de Emine Sevgi Özdamar y Yoko Tawada traducidas al español
No full textLa creciente mezcla cultural y lingüística de nuestro mundo contemporáneo se manifiesta también en la llamada literatura intercultural. Este «género» destaca por un uso innovador de la lengua de escritura, en la que, además, resuenan ecos de la primera lengua de las autoras y autores. Este trabajo investiga hasta qué punto y de qué maneras se plasma la interculturalidad en la dimensión lingüística y estética de los textos cuando se traducen a una tercera lengua. El trabajo se centra en cuatro obras de dos autoras que escriben en alemán –Emine Sevgi Özdamar, de origen turco, y Yoko Tawada, de origen japonés– y sus traducciones al español, concretamente en tres elementos microtextuales portadores de interculturalidad: las metáforas, las expresiones fraseológicas modificadas y los compuestos creados ad hoc. El análisis muestra que, con matizaciones, se conserva el carácter innovador y la «extrañeza» de estos elementos en las traducciones.The growing cultural and linguistic fusion of our contemporary world also becomes evident in what is known as intercultural literature. Characteristic of this “genre” is the innovative use of the language in which it is written, as well as echoes from the authors' first language. This work investigates the extent to which and the ways in which interculturality is reflected in the linguistic and aesthetic dimensions of texts when they are translated into a third language. The study focuses on four works by two authors who write in German —Emine Sevgi Özdamar, of Turkish origin, and Yoko Tawada, of Japanese origin— and their translations into Spanish, specifically on three microtextual elements that convey interculturality: metaphors, modified idiomatic expressions, and ad hoc compounds. The analysis shows that, with some nuances, the innovative character and “strangeness” of these elements are preserved in the translations.Programa de Doctorat en Llengües Aplicades, Literatura i Traducci
Influence of vehicle–track–bridge–soil interaction on the dynamic behaviour of railway bridges for accurate prediction of their vibratory response
No full textCompendi d'articles, Doctorat internacionalRailway transport has experienced a sustained development in recent decades characterised by increases in the travelling speed and the operating capacity of many railway lines. As these conditions are also expected in the long-term, they pose a significant challenge for the infrastructure, as it will have to withstand more demanding conditions. Thus, a thorough understanding of the train-induced vibration problem in railway bridges is key to ensuring the required levels of quality, safety and reliability in these critical structures. However, their dynamic behaviour is complex and is affected by multiple factors, among which the vehicle–track–bridge–soil interaction is particularly important. For this reason, the main objective of this thesis is to investigate its influence on the dynamic response of railway bridges with the aim of providing deeper insight into the phenomena involved and to achieve more accurate predictions of the bridge performance under operating conditions.Programa de Doctorat en Tecnologies Industrials i Material
Cooperative Robots for Construction — Material Handling and Stigmergic Methods
No full textDoctorat internacionalAutonomous robotic systems are poised to transform the construction industry by enabling teams of mobile robots to collaborate on material handling and assembly tasks. This dissertation advances the state of the art in cooperative mobile robotics for construction through an integrated exploration of hardware development, control architecture, simulation, and experimental validation. We design and implement a novel omnidirectional robot platform with a modular design and a friction-based lifting mechanism, allowing multiple robots to jointly lift and transport building materials without the need for complex grippers. Using this platform, a distributed control architecture orchestrates multi-robot coordination, and we systematically evaluate how key parameters – including robot mass, movement speed, team size, and task allocation strategy – impact the efficiency of both individual and cooperative operations. In parallel, drawing inspiration from social insects, we investigate stigmergic construction methods as a decentralized approach to multi-robot assembly. Using a custom lightweight simulator and high-fidelity ARGoS simulations, we develop and assess rule-based strategies in which robots coordinate indirectly by modifying their environment. These experiments demonstrate that simple local interaction rules can give rise to complex emergent structures. We also introduce a gripper tool design for block manipulation to bridge the gap between simulation and physical implementation of stigmergic building. Overall, the results validate the feasibility of employing cooperative robots for both shared-load material handling and decentralized construction. This work provides new insights into the design of multi-robot platforms and control frameworks for the construction domain, and it outlines practical guidelines to inform future robotic construction systems.Programa de Doctorat en Informàtic
Improving heat-to-electricity energy conversion with thermoelectric materials by means of electrochemical strategies
No full textCompendi d'articlesApproximately 72% of global energy consumption is lost in the form of waste heat. Thermoelectric (TE) devices have gained significant attention owing to their potential to transform heat into electricity, thus contributing to mitigate the present energy crisis. The TE performance is evaluated by the figure of merit zT=S2σT/κ, where S denotes the Seebeck coefficient, σ is the electrical conductivity, T represents the absolute temperature, and κ refers the thermal conductivity. Therefore, obtaining a high zT requires a large power factor (PF=S2σ) together with low κ. This thesis explores the enhancement of the PF in PEDOT:PSS, Ag-ZnO composite, bismuth/antimony telluride alloys, and Sb-doped SnO2 through electrochemical strategies. Upon treatment with 4,4'-bipyridine or LiBF4, PEDOT:PSS exhibited over 3 times PF enhancements. Ag-ZnO combined with BMII ionic liquid resulted in a 1.5-fold increase in the PF. Sb-doped SnO2 functionalized with redox molecules produced 2.5-fold PF improvements.Programa de Doctorat en Tecnologies Industrials i Material
