Dynamics of metallic glasses explored by mechanical relaxation
Dynamic mechanical analysis (DMA) is often used to explore the relaxation dynamics of metallic glasses (MGs). Secondary relaxations in metallic glasses appear as an excess wing, as a shoulder of the primary relaxation peak ...
Dynamics of oligotrophic pelagic environments:North western Mediterranean sea and subtropical north Atlantic
The response of phytoplankton to various ecological forcings was examined in the upper waters of the NW Mediterranean (MED) and the subtropical North Atlantic (NA) from field observations, analysis of historical data sets ...
Dynamics of optically levitated nanoparticles in high vacuum
Nanotechnology was named one of the key enabling technologies by the European Commission and its tremendous impact was envisioned early by 20th century physicist R.Feynman in his now oft-quoted talk "Plenty of Room at the ...
Dynamics of posidonia oceanica meadows
[cat] Aquesta tesi conté l’estudi de la dinàmica de patrons de vegetació a les praderes de Posidonia oceanica. El primer capítol presenta diferents casos de formació de patrons de vegetació a diferents ecosistemes, les ...
Dynamics of progesterone receptor interactors in breast cancer cells upon hormone exposure
El receptor de la progesterona és un regulador clau per la proliferació de les cèl·lules de càncer de mama dependents d’hormona. El mecanisme d’acció del PR ha tingut un paper important en la resolució del mecanisme molecular ...
Dynamics of quantum mixtures
At sufficiently low temperatures, fluids of bosonic particles may undergo a phase transition, below which a Bose-Einstein condensate (BEC) forms. The BEC is one of the most fundamental concepts in many-body quantum physics ...
Dynamics of spinor fermions
Ultracold atomic gases have established themselves as quantum systems, which are clean and offer a high degree of control over crucial parameters. They are well isolated from their environment and thus offer the possibility ...
Dynamics of spontaneous activity in the cerebral cortex across brain states
Spontaneous activity in the cerebral cortex changes in different brain states. During desynchronized brain states (e.g. wakefulness, REM sleep), populations of neurons in the cerebral cortex fire action potentials in a ...
Dynamics of Streptococcus pneumoniae in patients with Chronic Obstructive Pulmonary Disease
It is estimated that within a few years chronic obstructive pulmonary disease (COPD) will be the third leading cause of death worldwide. The morbidity and mortality associated with COPD are due, in part to acute exacerbation ...
Dynamics of subduction systems with opposite polarity in adjacent segments: application to the Westernmost Mediterranean
The objective of this thesis is to study the first-order dynamics of subduction systems characterized by opposite dip polarity in adjacent plate segments. The absence of previous studies analyzing the geodynamic evolution ...
Dynamics of the deep-sea teleost black scabbardfish (Aphanopus carbo Lowe, 1839) in the Northeast Atlantic
[eng] Aphanopus carbo (Lowe, 1839), the black scabbardfish, is a benthopelagic teleost with high commercial value in the NE Atlantic, especially in Madeira Archipelago and mainland Portugal. Given its commercial interest ...
Dynamics of the late-winter ENSO teleconnection to the North Atlantic-European region
The El Niño-Southern Oscillation (ENSO) is a natural mode of climate variability in the tropical Pacific, which not only perturbs the local atmosphere, but whose impacts can also reach remote, extra-tropical regions through ...
Dynamics of the membrane potential: studies of the membrane potential of Jurkat cells using wavelet and wavelet bispectral analysis
Fluctuations are fundamental for living organisms. They arguably result from interactions with the complex, and unpredictable environment, and can often be manifested as temporal variability. The cell must continually ...
Dynamics of Two Neuron Cellular Neural Networks
Les xarxes neuronals cel·lulars altrament anomenades CNNs, són un tipus de sistema dinàmic que relaciona diferents elements que s'anomenen neurones via unes plantilles de paràmetres. Aquest sistema queda completament ...
Dynamics of ultrafine particles and tropospheric ozone episodes
Atmospheric aerosol particles, particularly ultrafine particles (UFPs; particles with less than 100 nm in diameter), and tropospheric ozone (O3) are atmospheric pollutants highly influenced by photochemical reactions, i.e., ...
Dynamics of well being among immigrants
The broad objective of this thesis is to study the patterns of objective and subjective well-being among the immigrants in Europe. The main part of the thesis consists of three single-authored empirical chapters. The first ...
Dynamics, evolution and information in nonlinear dynamical systems of replicators
En aquesta tesi he investigat diversos camps de la biologia que podrien englobar-se en la disciplina general dels sistemes no lineals de replicadors. Els treballs presentats en aquesta tesis investiguen diversos fenomens ...
DYRK1A in cancer: good or evil? : Defining properties of DYRK1A kinase as a novel tumor driver
DYRK (dual-specificity tyrosine-regulated kinases) is an evolutionary conserved family of protein kinases involved in the regulation of cellular processes, such as proliferation and survival, which play pivotal role in ...
Dyskinesia in first-episode schizophrenic patients treated with second generation antipsychotics. Abnormal movements and schizophrenia outcome
Molts trastorns del moviment observats en pacients esquizofrènics passen desapercebuts, especialment els de lleu o moderada intensitat o bé els associats amb anosognosia. El valor dels moviments extrapiramidals i específicament ...
DysWebxia : a text accessibility model for people with dyslexia
Worldwide, 10% of the population has dyslexia, a cognitive disability that reduces readability and comprehension of written information. The goal of this thesis is to make text more accessible for people with dyslexia by ...
