[eng] This doctoral thesis deals with the study of the collective behavior of active particles using computacional simulations of semi-dilute solutions of microswimmers. Results are obtained for the polar order parameter, ...
[eng] This thesis develops, validates, and explores applications of the Franzese-Stanley (FS) coarse-grained model for bulk water, ultimately intended to represent the solvent in large-scale simulations of biological ...
In the present thesis, single-molecule experiments have been carried out using optical tweezers with a temperature controller. Employing equilibrium and non-equilibrium experiments, the free energy, enthalpy, and entropy ...
Most systems in Nature manifest complex transport phenomena arising from the interplay of multiple time and length scales, be them intrinsic in the system’s dynamics or externally enforced. It is the case, for instance, ...
[eng] This thesis delves into the study of catalytic Janus particles (AP) that convert chemical energy into mechanical motion, resulting in energy dissipation. Understanding this dissipation is challenging due to the ...
[eng] This thesis will present a body of articles on the research topic of soft matter. Soft matter is a research subfield of condensed matter, where the energy required for deforming the media is comparable to that of ...
[eng] The word "emergence" refers to the formation of collective behaviors, actions not undertaken by the components of a system when isolated. On one hand, we have the components—particles or agents, ranging from water ...
Most of the real-world complex systems are best described as complex networks and can be mathematically described as oscillatory systems, coupled with the neighbours through the connections of the network. The flashing of ...
Complex networks are mathematical representations of the interaction patterns of complex systems. During the last 20 years of Network Science, it has been recognized that networks from utterly different domains exhibit ...
[eng] This thesis presents the recent results achieved during my Ph.D. This is a research project in the field of condensed matter physics, under the supervision of Dr. Michael Foerster of the ALBA Synchrotron and Dr. ...
Living organisms and systems are continually converting energy, either internally stored or transduced from their surroundings, into motion. This activity and the resulting self-propulsion constantly push these biological ...
The topics dealt with in this thesis are all part of the general problem of social consensus, namely how a convention flourish and decay and what motivates people to conform to it. Examples range from driving on the right ...
The goal of this thesis is studying hydrodynamic effects on active colloidal suspensions. Hydrodynamic interaction is propagated through the fluid in which the colloids displace due to the flow they create during their ...
In this thesis, we employ noise-correlation force spectroscopy measurements using LOT to extract valuable information about the passive and active fluctuations of DNA molecules and red blood cells. We have chosen the laser ...
[eng] A set of disordered interacting building blocks may form ordered structures via self-assembly. External intervention in the system through the addition of chemical species or the application of forces leads to different ...
[cat] Entre el 1924 i el 1927 a través de la mecànica quàntica va començar a entreveure’s la idea de que alguns sistemes estaven formats pel que avui dia anomenem “partícules indistingibles”. Aquesta nova percepció de la ...
[eng] Over the past few decades, the use of complex networks to describe the properties of systems of many interacting particles has become widespread in many fields of science. Surprisingly, networks from disparate ...
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 ...
[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 ...
