• #### Modeling dengue immune responses mediated by antibodies: A qualitative study ﻿

(2021-09-01)
Dengue fever is a viral mosquito-borne infection and a major international public health concern. With 2.5 billion people at risk of acquiring the infection around the world, disease severity is influenced by the immunological ...

• #### Modelling COVID 19 in the Basque Country from introduction to control measure response ﻿

(2020-10)
In March 2020, a multidisciplinary task force (so‐called Basque Modelling Task Force, BMTF) was created to assist the Basque health managers and Government during the COVID‐19 responses. BMTF is a modelling team, working ...
• #### A multiscale network-based model of contagion dynamics: heterogeneity, spatial distancing and vaccination ﻿

(2021)
Lockdown and vaccination policies have been the major concern in the last year in order to contain the SARS-CoV-2 infection during the COVID-19 pandemic. In this paper we present a model able to evaluate alternative lockdown ...
• #### Numerical approximations for fractional elliptic equations via the method of semigroups ﻿

(2020)
We provide a novel approach to the numerical solution of the family of nonlocal elliptic equations $(-\Delta)^su=f$ in $\Omega$, subject to some homogeneous boundary conditions $\mathcal{B}(u)=0$ on $\partial \Omega$, where ...
• #### Numerical simulation of a susceptible-exposed-infectious space-continuous model for the spread of rabies in raccoons across a realistic landscape ﻿

(2013-12-31)
We introduce a numerical model for the spread of a lethal infectious disease in wildlife. The reference model is a Susceptible-Exposed-Infectious system where the spatial component of the dynamics is modelled by a diffusion ...
• #### Optimized schwarz methods and model adaptivity in electrocardiology simulations ﻿

(2014-12-31)
[No abstract available]
• #### Optimized schwarz methods for the bidomain system in electrocardiology ﻿

(2013-12-31)
The propagation of the action potential in the heart chambers is accurately described by the Bidomain model, which is commonly accepted and used in the specialistic literature. However, its mathematical structure of a ...
• #### Optimized Schwarz Methods in the Stokes-Darcy Coupling ﻿

(2018-10-16)
This article studies optimized Schwarz methods for the Stokes–Darcy problem. Robin transmission conditions are introduced, and the coupled problem is reduced to a suitable interface system that can be solved using Krylov ...
• #### Parallelizing the Kolmogorov-Fokker-Planck Equation ﻿

(2015-12-31)
We design two parallel schemes, based on Schwarz Waveform Relaxation (SWR) procedures, for the numerical solution of the Kolmogorov equation. The latter is a simplified version of the Fokker-Planck equation describing the ...
• #### Patient-specific computational modeling of Cortical Spreading Depression via Diffusion Tensor Imaging ﻿

(2016-06-29)
Cortical Spreading Depression (CSD), a depolarization wave originat- ing in the visual cortex and traveling towards the frontal lobe, is com- monly accepted as a correlate of migraine visual aura. As of today, little is ...
• #### Patient-specific modelling of cortical spreading depression applied to migraine studies ﻿

(2019-06-17)
Migraine is a common neurological disorder and one-third of migraine patients suffer from migraine aura, a perceptual disturbance preceding the typically unilateral headache. Cortical spreading depression (CSD), a ...
• #### Qualitative analysis of kinetic-based models for tumor-immune system interaction ﻿

(2018-08)
A mathematical model, based on a mesoscopic approach, describing the competition between tumor cells and immune system in terms of kinetic integro-differential equations is presented. Four interacting populations are ...
• #### An RBF-FD closest point method for solving PDEs on surfaces ﻿

(2018)
Partial differential equations (PDEs) on surfaces appear in many applications throughout the natural and applied sciences. The classical closest point method (Ruuth and Merriman, J. Comput. Phys. 227(3):1943-1961, ...
• #### Reproduction ratio and growth rates: Measures for an unfolding pandemic ﻿

(2020-05)
The initial exponential growth rate of an epidemic is an important measure that follows directly from data at hand, commonly used to infer the basic reproduction number. As the growth rates λ(t) of tested positive COVID-19 ...
• #### SDE-driven modeling of phenotypically heterogeneous tumors: The influence of cancer cell stemness ﻿

(2019)
We deduce cell population models describing the evolution of a tumor (possibly interacting with its environment of healthy cells) with the aid of differential equations. Thereby, different subpopulations of cancer cells ...
• #### SHAR and effective SIR models: from dengue fever toy models to a COVID-19 fully parametrized SHARUCD framework ﻿

(2020)
We review basic models of severe/hospitalized and mild/asymptomatic infection spreading (with classes of susceptibles S, hopsitalized H, asymptomatic A and recovered R, hence SHAR-models) and develop the notion of comparing ...
• #### A space-fractional bidomain framework for cardiac electrophysiology: 1D alternans dynamics ﻿

(2021)
Cardiac electrophysiology modeling deals with a complex network of excitable cells forming an intricate syncytium: the heart. The electrical activity of the heart shows recurrent spatial patterns of activation, known as ...
• #### A space-fractional Monodomain model for cardiac electrophysiology combining anisotropy and heterogeneity on realistic geometries ﻿

(2017-10-04)
Classical models of electrophysiology do not typically account for the effects of high structural heterogeneity in the spatio-temporal description of excitation waves propagation. We consider a modification of the Monodomain ...
• #### Spectral analysis of a block-triangular preconditioner for the bidomain system in electrocardiology ﻿

(2012-12-31)
In this paper we analyze in detail the spectral properties of the block-triangular preconditioner introduced by Gerardo-Giorda et al. [J. Comput. Phys., 228 (2009), pp. 3625-3639] for the Bidomain system in non-symmetric ...
