On the role of oscillatory dynamics in neural communication
In this Thesis we consider problems concerning brain oscillations generated across the interaction between excitatory (E) and inhibitory (I) cells. We explore how two neuronal groups with underlying oscillatory activity ...
On the role of performance interference in consolidated environments
With the advent of resource shared environments such as the Cloud, virtualization has become the de facto standard for server consolidation. While consolidation improves utilization, it causes performance-interference ...
On the scalability limits of communication networks to the nanoscale
Nanosystems, integrated systems with a total size of a few micrometers, are capable of interacting at the nanoscale, but their short operating range limits their usefulness in practical macro-scale scenarios. Nanonetworks, ...
On the scalability of LISP and advanced overlaid services
In just four decades the Internet has gone from a lab experiment to a worldwide, business critical infrastructure that caters to the communication needs of almost a half of the Earth's population. With these figures on its ...
On the Scale Invariance of certain Complex Systems
La Ciència de la Complexitat és un camp d'estudi interdisciplinari que aplica conceptes i mètodes de la física estadística i la teoria dels fenòmens crítics a altres camps, des de la Biologia a l'Economia, la Geologia o ...
On the service placement in community network micro-clouds
Community networks (CNs) have gained momentum in the last few years in response to the growing demand for network connectivity in rural and urban areas. These networks, owned and managed by volunteers, offer various services ...
On the Slope and Geography of Fibred Surfaces and Threefolds.
In this tesis we study numerical propieties of surfaces and threefolds, mainly fibred over curves, the so called "slope" of the fibration. We prove partially a conjecture of Fujita on the semiampleness of the direct image ...
On the Steps of Cell-to-Cell HIV Transmission
A diferència de la infecció per virus lliure, la transmissió del VIH de cèl·lula a cèl·lula és un mecanisme altament eficient i citopàtic degut a l'establiment de les sinapsis virològiques induïdes per l'embolcall del virus ...
On the stratification of smooth plane curves by automorphism groups
Curvas proyectivas no singulares sobre un cuerpo con grupo de automorfismo no trivial son de gran interés en Geometría Aritmética. En la tesis, estudiamos la estratificación de las curvas planas no singulares (de género ...
On the structure of graphs without short cycles
The objective of this thesis is to study cages, constructions and properties of such families of graphs. For this, the study of graphs without short cycles plays a fundamental role in order to develop some knowledge on ...
On the study of 3D structure of proteins for developing new algorithms to complete the interactome and cell signalling networks
Proteins are indispensable players in virtually all biological events. The functions of proteins are determined by their three dimensional (3D) structure and coordinated through intricate networks of protein-protein ...
On the Tamagawa number conjecture
En la tesis es resolt la conjectura del nombre de Tamagawa en dues situacions: per a corbes el.líptiques E+ definides sobre Q amb multiplicació complexa donada per un cos imaginari quadràtic K, i per a caràcters de Hecke Ak--K*.
On the theory of cell migration: durotaxis and chemotaxis
Cell migration is a fundamental element in a variety of physiological and pathological processes. Alteration of its regulatory mechanisms leads to loss of adhesion and increased motility, critical steps in the initial ...
On the track of cellular ecology. Methodological improvements and contributions of single-cell phosphatase activity on the ecology of phytoplankton in Pyrenean lakes
Comparative studies between different enzyme labelled fluorescence (ELF) protocols and fluorescence quantification methods were performed to improve the quantification of single-cell phosphatase activity (PA) measurements ...
On the upscaling of organic solar cells based on non-fullerene acceptors
En els últims anys, la tecnologia fotovoltaica orgànica (OPV, per les seves sigles en anglès) ha despertat l’atenció de tant la comunitat científica com la industrial, a causa de les seves altes eficiències de conversió ...
On the usage of lipophilic descriptors for molecular similarity evaluation
Three-dimensional ligand-based virtual screening methods have been used for many years in drug discovery, with a variable success depending on different factors, such as the complexity of the target system or the suitability ...
On the use of advanced pattern recognition techniques for the analysis of MRS and MRSI data in neuro-oncology
El cáncer es una de las principales causas de muerte en el mundo. Los tumores cerebrales tienen una incidencia relativamente baja en comparación con otras patologías cancerígenas más generalizadas, pero la prognosis de ...
On the use of decadal predictions for agricultural climate services: bridging the gap between service providers and users
(English) Unfavorable and extreme climate events such as drought and heat stress heavily impacts the agriculture sector and food security globally, and the impact of these climate hazards is expected to increase over the ...
On the use of energy decomposition analyses to unravel the origin of the relative stabilities of isomers
Structural isomers are molecules that have the same number and type of atoms but arranged in different manner. The isomerization energy is the energy difference between two isomers, i.e. the energy cost corresponding to ...
