Unravelling the role of transposable elements in the eukaryotic stress response
Environmental stress is a major aspect of life and a limiting factor for the survival and distribution of species. Understanding the organismal stress response and the developed coping mechanisms is indispensable in order ...
Unravelling the role of zinc in the resistance to necrotrophic fungi in arabidopsis thaliana and noccaea caerulescens
El zinc es un micronutriente esencial para las plantas, pero tóxico a concentraciones elevadas. La mayoría de las plantas adaptadas a suelos metalíferos excluyen el exceso de metales de sus tejidos. Sin embargo, algunas ...
Unravelling the roles of an alternatively spliced microexon in Daam1 in nervous system development and function
Microexons are an unusual form of alternative splicing with high evolutionary conservation, however, their functions are still far from being understood. In this thesis, we focused on a neuronal-specific microexon that ...
Unravelling the underlying mechanisms involved in the beneficial effects of DPP-4 inhibitors in early stages of diabetic retinopathy
La retinopatia diabètica (RD) és una dels complicacions més freqüents de la diabetis i és considerada la causa principal de ceguesa entre la població laboralment activa als països més desenvolupats. Malgrat això, els ...
Unstable motions in the three body problem
(English) The 3 Body Problem (3BP) models the motion of three bodies interacting via Newtonian gravitation. It is called restricted when one body has zero mass and the other two, the primaries, have strictly positive masses. ...
Unsteady laminar convection in cylindrical domains: numerical studies and application to solar water storage tanks
Los dispositivos de almacenamiento de energía térmica son ampliamente usados en diversos sistemas térmicos caracterizados por un desfase temporal entre la producción de energia y su consumo, como es el caso de los sistemas ...
Unstructured P2P social search query routing algorithms for agentified social networks
The village paradigm presents some benefits compared with the library paradigm; people can adapt the answer content as a function of who is requesting the information, or furthermore, people can perform clarifications of ...
Unsupervised and attention approaches for deep learning speaker recognition
(English) The thesis presents various contributions to the field of speaker recognition. In the first part of the thesis, the focus is on unsupervised methods for speaker recognition. This includes a method that uses Deep ...
Unsupervised Band Selection and Segmentation in Hyper/Multispectral Images
The title of the thesis focuses the attention on hyperspectral image segmentation, that is, we want to detect salient regions in a hyperspectral image and isolate them as accurate as possible. This purpose presents two ...
Unsupervised entity linking using graph-based semantic similarity
Nowadays, the human textual data constitutes a great proportion of the shared information resources such as World Wide Web (WWW). Social networks, news and learning resources as well as Knowledge Bases (KBs) are just the ...
Unsupervised Identification of the User’s Query Intent in Web Search
This doctoral work focuses on identifying and understanding the intents that motivate a user to perform a search on the Web. To this end, we apply machine learning models that do not require more information than the one ...
Unsupervised learning for expressive speech synthesis
Nowadays, especially with the upswing of neural networks, speech synthesis is almost totally data driven. The goal of this thesis is to provide methods for automatic and unsupervised learning from data for expressive speech ...
Unsupervised learning for parametric optimization in wireless networks
This thesis studies parametric optimization in cellular and cell-free networks, exploring data-based and expert-based paradigms. Power allocation and power control, which adjust the transmit power to meet different fairness ...
Unsupervised learning of relation detection patterns
L'extracció d'informació és l'àrea del processament de llenguatge natural l'objectiu de la qual és l'obtenir dades estructurades a partir de la informació rellevant continguda en fragments textuals. L'extracció d'informació ...
Untangling chromatin: investigating the role of transcription, supercoiling and topoisomerases in genome organization
La organización del genoma en células mamíferas sigue siendo en gran parte desconocida. Un nivel fundamental de organización se considera el bucle de cromatina, que consiste en una región de ADN atrapada en el interior ...
Unveiling Nanomedicine Using Correlative Super-Resolution and Electron Microscopy
Els tractaments actuals contra el càncer més enllà de la cirurgia inclouen teràpies que tenen un èxit limitat. Això és degut a efectes secundaris greus, que condueixen a una qualitat de vida reduïda i una baixa efectivitat. ...
Unveiling new molecular Opisthokonta diversity : A perspective from evolutionary genomics
Opisthokonta is an eukaryotic supergroup that contains Metazoa, Fungi and their unicellular relatives. Therefore, this group provides an ideal framework to study distinct unicellular-multicellular transitions, among them, ...
Unveiling novel components of the protein complex responsible for cGMP synthesis in retinal photoreceptors: role in cell physiology and disease
In photoreceptor cells of the retina, light triggers a protein G-mediated enzymatic cascade that leads to hydrolysis of cGMP. The drop in cGMP levels causes the closure of cGMP-channel at the plasma membrane, decreasing ...
Unveiling novel functions of the trascriptional repressor HDAC7 in B lymphocyte development
B lymphopoiesis is the result of several cell lineage choices and differentiation steps whose perturbation leads to B cell malignancies. Cellular transitions for B cell generation have been associated with gene activation ...
Unveiling Protein-Substrate Interactions and Conformations that Influence Catalysis in Carbohydrate-Active Enzymes
Enzymes have attracted the attention of chemists and biologists since long ago due to their molecular complexity and tremendous efficiency. They are highly specific catalysts that make chemical reactions possible at mild ...
