6 p, 3.0 MB Minimum action path theory reveals the details of stochastic transitions out of oscillatory states / Cruz Moreno, Roberto de la (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Perez-Carrasco, Ruben (University College London. Department of Mathematics (UK)) ; Guerrero, Pilar (University College London. Department of Mathematics (UK)) ; Alarcón Cor, Tomás (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Page, Karen M. (University College London. Department of Mathematics (UK)) ; Universitat Autònoma de Barcelona. Centre de Recerca Matemàtica
Cell state determination is the outcome of intrinsically stochastic biochemical reactions. Transitions between such states are studied as noise-driven escape problems in the chemical species space. Escape can occur via multiple possible multidimensional paths, with probabilities depending nonlocally on the noise. [...]

18 p, 918.2 KB Coarse-graining and hybrid methods for efficient simulation of stochastic multi-scale models of tumour growth / Cruz Moreno, Roberto de la, (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Guerrero, Pilar (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Calvo, Juan (Universidad de Granada. Departmento de Matemática Aplicada) ; Alarcón Cor, Tomás (Centre de Recerca Matemàtica)
The development of hybrid methodologies is of current interest in both multi-scale modelling and stochastic reaction-diffusion systems regarding their applications to biology. We formulate a hybrid method for stochastic multi-scale models of cells populations that extends the remit of existing hybrid methods for reaction-diffusion systems. [...]

23 p, 2.3 MB Stochastic multi-scale models of competition within heterogeneous cellular populations : Simulation methods and mean-field analysis / Cruz Moreno, Roberto de la (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Guerrero, Pilar (University College London. Department of Mathematics) ; Spill, Fabian (Boston University. Department of Biomedical Engineering) ; Alarcón Cor, Tomás (Centre de Recerca Matemàtica)
We propose a modelling framework to analyse the stochastic behaviour of heterogeneous, multi-scale cellular populations. We illustrate our methodology with a particular example in which we study a population with an oxygen-regulated proliferation rate. [...]

(University of Oxford. Wolfson Centre for Mathematical Biology) ; Byrne, Helen (University of Oxford. Wolfson Centre for Mathematical Biology)
Reaction-diffusion models are used to describe systems in fields as diverse as physics, chemistry, ecology and biology. The fundamental quantities in such models are individual entities such as atoms and molecules, bacteria, cells or animals, which move and/or react in a stochastic manner. [...]

El cáncer es una de las principales causas de muerte en el mundo. A pesar de todos los recursos invertidos en la investigación para el desarrollo de nuevas terapias, los tratamientos más usados en la lucha contra el cáncer siguen siendo terapias inespecíficas (cirugía, radioterapia y quimioterapia) que afectan tanto a las células cancerígenas como a las sanas. [...]
Cancer is one of the principal causes of death in the world . Despite all the resources invested in research for the development of new targeted therapies, the most used treatments to fight cancer continue to be non-specific therapies, such as surgery, radiotherapy and chemotherapy, that affect both healthy and cancer cells.

20 p, 248.7 KB On the analysis of travelling waves to a nonlinear flux limited reaction-diffusion equation / Campos, Juan ; Guerrero, Pilar ; Sánchez, Óscar ; Soler, Juan ; Universitat Autònoma de Barcelona. Centre de Recerca Matemàtica
In this paper we study the existence and qualitative properties of travelling waves associated to a nonlinear flux limited partial differential equation coupled to a Fisher-Kolmogorov-Petrovskii-Piskunov type reaction term. [...]

35 p, 487.6 KB Wellposedness of a nonlinear, logarithmic Schrödinger equation of Doebner-Goldin type modeling quantum dissipation / Guerrero, Pilar ; López, J. L. ; Montejo-Gámez, J. ; Nieto, J. ; Universitat Autònoma de Barcelona. Centre de Recerca Matemàtica
This paper is concerned with the modeling and analysis of quantum dissipation phenomena in the Schrödinger picture. More precisely, we do investigate in detail a dissipative, nonlinear Schrödinger equation somehow accounting for quantum Fokker-Planck effects, and how it is drastically reduced to a simpler logarithmic equation via a nonlinear gauge transformation in such a way that the physics underlying both problems keeps unaltered. [...]
