Statistical thermodynamics of long-range interacting systems and near-field thermal radiation
Two main topics are examined in this thesis: classical systems with long-range interactions and thermal radiation in the near-field regime. In the first part, we present a thermodynamic approach describing systems with ...
Spatio-temporal dynamics of intercellular Notch signaling: a modeling approach
Intercellular signalling is a mechanism by which cells communicate and mediate coordinated responses. In this Thesis we perform theoretical and computational analyses to evaluate spatio-temporal organizations that can arise ...
Anomalous transport and diffusion of Brownian particles on disordered landscapes
Brownian motion refers to the random movement that undergo mesosized particles suspended in a simple sol- vent. Einstein’s probabilistic approach to the Brownian motion is founded on the principal that it is on account of ...
Giant caloric effects in the vicinity of first-order phase transitions
Solid state materials are candidates to exhibit a large field-driven thermal response in the vicinity of first-order transitions. The strong sensitivity of the transition temperature with the applied field and the latent ...
Prospects of microwave spectrometry for vascular stent monitoring. Towards a non-invasive and non-ionizing follow-up alternative
Throughout this thesis we have assessed the prospects of microwave spectrometry (MWS) as a non-ionizing non-invasive monitoring alternative for stented patients in a very early proof-of-concept stage. In Chapter 1 we have ...
Linear and nonlinear approaches to unravel dynamics and connectivity in neuronal cultures
In the present thesis, we propose to explore neuronal circuits at the mesoscale, an approach in which one monitors small populations of few thousand neurons and concentrates in the emergence of collective behavior. In our ...
Forces and flows in cells and tissues. Blebs, active gels, and collective cell migration
In this thesis, we have studied mechanical aspects of some biological processes in cells and tissues, which we addressed by developing theoretical models based on the physics of soft active matter. The thesis contains three ...
Nanofabrication, simulation and optical characterization of plasmonic nanostructures
This thesis is devoted to the nanofabrication, simulation and optical characterization of different plasmonic nanostructures. When an electromagnetic wave reaches a metallic nanostructure, it can give rise to collective ...
Activity Mediated Interactions in Soft Matter. Structure, Interactions, and Phase Transitions
In this thesis we asses the phenomena of arising interactions in soft matter in coexistence with soft active matter. As a non-equilibrium bath we introduce ensembles of self-propelled particles, granular shaken beds, and ...
Free energy and information-content measurements in thermodynamic and molecular ensembles
Single-molecule experiments have emerged as a powerful tool that allow researchers to investigate the physical behavior of individual molecules with unprecedented resolution. The feasibility exerting forces at the piconewton ...
Revealing DNA dynamics from atomistic to genomic level by multiscale computational approaches
The study of DNA from atomistic to mesoscopic level and connecting different resolution levels constitutes a major challenge since the new millennium. In the early 2000s, experiments could resolve for the first time the ...
Dynamics and Effective Connectivity in Bi- and Three–dimensional Neuronal Cultures: from Self–organization to Engineering
This thesis was part of the European consortium MESOBRAIN, a team of 5 organizations that joined efforts in nanofabrication, cell culturing, imaging and data analysis to build tailored human 3D networks. The thesis timing ...
Out-of-equilibrium dynamics in driven and active magnetic colloids
In this thesis we investigate the structure formation and the out-of-equilibrium dynamics of driven and active magnetic colloids. The interactions in our system were tuned in situ by using external fields, with the aim of ...
Giant caloric and multicaloric effects in magnetic alloys
The urgent need to reduce our footprint on the earth environment is leading to ever more stringent commitments to decrease greenhouse gases emissions, which entails one of the greatest challenges that mankind has to tackle. ...
Nonlinear and spatial dynamics for multicellular organisms
The development of living systems, from their conception to their death, involves a very tight coordination between gene expression in time and space. The processes involved in such an unfolding do not solely depend on the ...
Modelling the dynamics of cellular membranes
Membranes are present in all cells, in some viruses, and are involved in all kinds of biological functions. The goal of this thesis is to expand our knowledge of this element, in hope that this -on top of all the other ...
Non-Equilibrium Dynamics of Driven and Confined Colloidal Systems
[eng] In this thesis, I study the behavior of confined colloidal particles in aqueous suspension driven through an optical potential. For this purpose, I use micro-meter polystyrene particles, which I confine in the optical ...
Functional connectivity at multiple scales: From neuronal cultures to human brain
[eng] One of the greatest challenges in the field of neuroscience is to obtain an accurate functional description of the brain that allows us to understand the functioning of higher complexity cognitive processes such ...
Colloidal dynamics in artificial particle ice systems
[eng] Geometrical frustration is a general phenomenon influencing the behavior of diverse natural systems across different length scales. Geometrical frustration arises when the symmetry of the interaction among building ...
