Phase Behavior of Active Swimmers in Depletants: Molecular Dynamics and Integral Equation Theory

2013

We study the structure and phase behavior of a binary mixture where one of the components is self-propelling in nature. The inter-particle interactions in the system were taken from the Asakura-Oosawa model, for colloid-polymer mixtures, for which the phase diagram is known. In the current model version the colloid particles were made active using the Vicsek model for self-propelling particles. The resultant active system was studied by molecular dynamics methods and integral equation theory. Both methods produce results consistent with each other and demonstrate that the Vicsek model based activity facilitates phase separation, thus broadening the coexistence region.

Implementación de un display 3D basado en imagen integral

2018

Desde hace varios años, el desarrollo y la evolución de tecnologías capaces de registrar y/o reconstruir información 3D está en auge, principalmente debido al gran interés que despierta este campo de estudio. Entre estas tecnologías, destaca la técnica de Imagen Integral, debido principalmente a su capacidad de generar un imagen 3D que proporciona al sistema visual una respuesta similar a la que obtendría percibiendo un objeto 3D real. Aunque esta técnica no está exenta de limitaciones, se están realizando prometedores avances para resolver sus principales inconvenientes. En esta Tesis se estudia la técnica de imagen integral con el objetivo de implementar un monitor 3D que sir…

Limits of Sobolev homeomorphisms

2017

Let X; Y subset of R-2 be topologically equivalent bounded Lipschitz domains. We prove that weak and strong limits of homeomorphisms h: X (onto)-> Y in the Sobolev space W-1,W-p (X, R-2), p >= 2; are the same. As an application, we establish the existence of 2D-traction free minimal deformations for fairly general energy integrals. Peer reviewed

On new efficient algorithms for PIMC and PIMD

2002

Abstract The properties of various algorithms, estimators, and high-temperature density matrix (HTDM) decompositions relevant for path integral simulations are discussed. It is shown that Fourier accelerated path integral molecular dynamics (PIMD) completely eliminates slowing down with increasing Trotter number P . A new primitive estimator of the kinetic energy for use in PIMD simulations is found to behave less pathologically than the original virial estimator. In particular, its variance does not increase significantly with P . Two non-primitive HTDM decompositions are compared as well: one decomposition used in the Takahashi Imada algorithm and another one based on an effective propaga…

Treatment of multiple traumatized anterior teeth associated with an alveolar bone fracture in a 20-year-old patient: A 3-year follow up

2014

Intrusive luxation is a type of recognizable luxation injury represented by a deeper axial displacement of the tooth toward the alveolar bone. Treatment strategies include waiting for the tooth to return to its position, immediate surgical repositioning, and repositioning through dental traction by orthodontic devices. The aim of this case report was to present the management of severe dental trauma and later restoration following IADT. A 20-year-old patient was presented after fainting at home four hours before, resulting in a dento-alveolar trauma. Clinical examinations revealed a traumatic intrusion, in 1.2, 1.1 and 2.1, uncomplicated crown fractures in 1.1 and 2.1 and a complicated crow…

Hard-sphere fluids in annular wedges: density distributions and depletion potentials.

2009

We analyze the density distribution and the adsorption of solvent hard spheres in an annular slit formed by two large solute spheres or a large solute and a wall at close distances by means of fundamental measure density functional theory, anisotropic integral equations and simulations. We find that the main features of the density distribution in the slit are described by an effective, two--dimensional system of disks in the vicinity of a central obstacle. For large solute--solvent size ratios, the resulting depletion force has a straightforward geometrical interpretation which gives a precise "colloidal" limit for the depletion interaction. For intermediate size ratios 5...10 and high sol…

La normativa en materia de violencia de género como garante de los derechos de las mujeres

2019

La violencia que se ejerce contra las mujeres es una violación de los derechos humanos muy extendida y en gran parte impune en todo el mundo. No podemos hablar de derechos humanos sin tener en cuenta los derechos de las mujeres que se ven conculcados, demasiadas veces, por la violencia machista. Para acabar con las violencias machistas habrá que hacer un abordaje integral en su tratamiento que afecte a todos los ámbitos de la vida (económico, político, religioso, cultural...), y también un esfuerzo en la equiparación de las diferentes legislaciones en cuanto al concepto de violencia de género The violence perpetrated against women is a violation of human rights that is widespread and largel…
