AIMS: We develop a new theoretical framework to generate Besançon Galaxy Model Fast Approximate Simulations (BGM FASt) to address fundamental questions of the Galactic structure and evolution performing multi-parameter ...
In this thesis we have presented a new method to search for tidal streams generated by globular clusters in the Gaia catalogue. This statistical method is based on the maximum likelihood technique to distinguish stream ...
Most of the efforts on the search and characterization of Earth-like exoplanets are currently focused on low mass stars. Some important properties related to the structure and processes in this type of stars are still ...
This project presents the study of luminescent devices and materials based on silicon for its use in the fabrication of an optical system that integrates light emitter, waveguide, and light sensor in a single chip obtained ...
The term light pollution refers to different harmful effects produced by artificial light sources. This phenomena affects observational astronomy, the flora and fauna of the species adapted to the natural cycles of light ...
The main goal of this thesis is to study the radiative decays produced in one of the four big detectors of LHC, LHCb, which focuses on the study of matter-antimatter asymmetry through b and c quarks. In particular, the ...
Biomolecular simulations have been widely used in the study of protein-ligand interactions; comprehending the mechanisms involved in the prediction of binding affinities would have a significant repercussion in the ...
The Gaia mission and its extensive catalogue of stars has marked the beginning of the Golden Age of Galactic dynamics. We have now access to the kinematics of more than a billion stars with which we can start ...
Nowadays, Nanotechnology is having an impact on practically every aspect of human life. It is a transformative technology that has influenced and will continue on electronics, computers, medicine, catalysis, energy, and ...
The goal of the present investigation is to examine the processing-structure-property relationships of multilayer graphene nanowall materials. Various plasma enhanced chemical vapor deposition (PECVD) processing parameters ...
[eng] This thesis focuses in the analysis of radative b-decays and rare strange decays, using data recorded by the LHCb, at the LHC during the Run 2 period. Two analyses are presented in the thesis, both flavour changing ...
The first confirmed detection of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found by radial velocity measurements in a four-day orbit around the nearby star 51 Pegasi by Mayor and ...
Spatial embedding and inherited metric constraints are a fundamental trait of biological neuronal circuits. However their role in shaping connectivity and dynamics has been often disregarded, with models of neuronal networks ...
This thesis studies Dark Energy, a central topic of Modern Cosmology, from different points of view. It covers from models and parametrizations to likelihood approximations for the observations of the Large Scale Structure ...
[eng] This doctoral work investigates nucleic acids' thermodynamic and kinetic properties. The main objective is the characterization of the energetics and the folding mechanisms driving the hybridization of DNA and RNA ...
[eng] Atmospheric aerosol is an ensemble of atmospheric pollutants with a severe impact on human health and Earth climate. Particulate Matter (PM) effects vary depending on the composition and size. However, current air ...
This thesis focuses on the synthesis of different types of NCs, their application to energy conversion and storage technologies, particularly LIBs, KIBs and DEFCs, and their structural transformation during electrochemical ...
The aim of this Ph.D. thesis is the synthesis and characterization of nanoparticles to understand and optimize their macroscopic properties. The manuscript is divided into seven chapters. Chapter 1 is a general introduction ...
Electronic machines and computers have experienced a huge development during the last four decades, mainly thanks to the continuous scaling down of the hardware responsible of information processing and storage (i.e. ...
[eng] Atmospheric aerosol particles are key for regulating Earth’s atmosphere processes, and are estimated to present an overall cooling effect on the Earth’s climate. Given the current climate change crisis, and the need ...
