Quantitative nanoscale imaging of synaptic protein organization
The arrival of super-resolution techniques has driven researchers to explore biological areas that were unreachable before. Such techniques not only allowed the improvement of spatial resolution in images but also the ...
Quantitative proteomic approaches for the characterization of bacterial wilt resistance mechanisms in tomato. lnsights on the role of P69 subtilisin-like proteases in defense
The plant pathogen Ralstonia solanacearum is the causal agent of the devastating disease known as bacterial wilt. This disease affects more than 200 plant species in over 50 families, including economically important crops ...
Quantitative risk assessment, aggregation functions and capital allocation problems
This work is focused on the study of risk measures and solutions to capital allocation problems, their suitability to answer practical questions in the framework of insurance and financial institutions and their connection ...
Quantitative structure fate relationships for multimedia environmental analysis
Key physicochemical properties for a wide spectrum of chemical pollutants are unknown. This thesis analyses the prospect of assessing the environmental distribution of chemicals directly from supervised learning algorithms ...
Quantitative Systems Toxicology Modeling for Neuronal Adverse Outcome
Els humans estan exposats a múltiples químics ambientals, molts amb efectes sobre la salut deficientment caracteritzats. Avaluar el risc químic requereix conèixer el perill, la relació dosi-resposta i l'exposició per ...
Quantum Algorithms for Solving Hard Constrained Optimization Problems
En aquesta investigació, s'han examinat tècniques d'optimització per resoldre problemes de restriccions i s'ha fet un estudi de l'era quàntica i de les empreses líders del mercat, com ara IBM, D-Wave, Google, Xanadu, ...
Quantum Aspects of Space and Time
In this thesis, we explore different ways in which spacetime exhibits peculiar properties when subjected to the rules of quantum mechanics. These rules are naturally implemented at the level of semiclassical physics, where ...
Quantum Brownian motion in Bose-Einstein condensates
Quantum Brownian motion is one of the most prominent examples of an open quantum system, a system which cannot be treated in isolation from its environment. The simplest method to study the dynamics of a system undergoing ...
Quantum Brownian motion revisited : extensions and applications
Quantum Brownian motion represents a paradigmatic model of open quantum system, namely a system which cannot be treated as an isolated one, because of the unavoidable interaction with the surrounding environment. In this ...
Quantum chemistry and conformational sampling meet together : a powerful approach to study and design metalloprotein reactivity
Metalloprotein are proteins containing metal ion cofactors. Compared to chemical catalysts, metalloproteins have a well-defined configuration around the active site which ensures higher specificity, selectivity and reaction ...
Quantum chemistry computations of the adsorption, diffusion and reactivity of atoms and light radicals on the surfaces of interstellar grains
Aquesta tesi presenta un estudi exhaustiu de la química dels grans interestel·lars utilitzant tècniques computacionals de darrera generació. Comprendre la química dels grans interestel·lars és essencial per desentranyar ...
Quantum Confinement of Gaseous Molecules in Nanostructures: Effects on the Dynamics and Internal Structure
Quantum confinement effects, understood as the changes on the structure and dynamics of a molecule when it goes from a free environment to a cavity with some characteristic length of the order of the nanometer, represent ...
Quantum control of single spin excitations in cold atomic quantum memories
Optical quantum memories are important devices in quantum information science. In particular, they are building blocks of quantum repeater architectures that have been proposed to increase the range of quantum communication ...
Quantum detection in time. Change Point and Sequential Analysis
Aquesta tesi tracta sobre detectar propietats de conjunts d’estats quàntics ordenats en el temps. No obstant, no tracta sobre la mesura del temps, sinó sobre la detecció de un senyal fet d’estats quàntics. S’aborden ...
Quantum dynamics of physicochemical processes in superfluid (4)He nanodroplets
The present thesis presents several theoretical studies on the dynamical processes of physicochemical interest involving superfluid helium (4He) nanodroplets. It has been developed a theoretical approach and computationally ...
Quantum effects in brane world scenarios: moduli stabilization and the hierarchy problem
El problema de la jerarquía se puede resolver en ciertos modelos de branas debido a<br/>que, en estos modelos, la separación entre la escala electrodébil y la de Planck<br/>depende del tamaño de las dimensiones extra. Éste ...
Quantum Effects on some low and high energy processes beyond the standard model
Elementary particle physics has made remarkable progress in the past two decades, both experimentally and theoretically. The success of the Standard Model (SM) has been overwhelming since it was proposed as the unified ...
Quantum entanglement and quantum state estimation = Entrelazado cuántico y estimación de estados cuánticos
[spa] En esta Tesis se ha realizado en el marco de la Información Cuántica, una nueva disciplina de la Física Teórica en la que se funden la Mecánica Cuántica con la Teoría de la Información. El estudio se ha centrado en ...
Quantum frecuency conversion for hybrid quantum networks
The ability to control the optical frequency of quantum state carriers (i.e. photons) is an important functionality for future quantum networks. It allows all matter quantum systems - nodes of the network - to be compatible ...
Quantum gauge theory simulation with ultracold atoms
The study of ultracold atoms constitutes one of the hottest areas of atomic, molecular, and optical physics and quantum optics. The experimental and theoretical achievements in the last three decades in the control and ...
