• #### Modeling cardiac structural heterogeneity via space-fractional differential equations ﻿

(2017)
We discuss here the use of non-local models in space and fractional order operators in the characterisation of structural complexity and the modeling of propagation in heterogeneous biological tissues. In the specific, we ...
• #### Modeling COVID-19: Challenges and results ﻿

(2020-10)
Weird times we are living in. While lots of technological, medical and scientific advances are generated in a short period of time, we are now fighting a pandemic, trying to stop the spread of a new virus that has not only ...
• #### 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 ...
• #### Modeling Dengue Immune Responses Mediated by Antibodies: Insights on the Biological Parameters to Describe Dengue Infections ﻿

(2022-03-18)
Dengue fever is a viral mosquito-borne disease, a significant global health concern, with more than one third of the world population at risk of acquiring the disease. Caused by 4 antigenically distinct but related virus ...
• #### Modeling secondary infections with temporary immunity and disease enhancement factor: Mechanisms for complex dynamics in simple epidemiological models ﻿

(2022-10-04)
Modeling insights for epidemiological scenarios characterized by chaotic dynamics have been largely unexplored. A rigorous analysis of such systems are essential for a real predictive power and a more accurate disease ...
• #### Modeling the initial phase of COVID-19 epidemic: The role of age and disease severity in the Basque Country, Spain ﻿

(2022-07-13)
Declared a pandemic by the World Health Organization (WHO), COVID-19 has spread rapidly around the globe. With eventually substantial global underestimation of infection, by the end of March 2022, more than 470 million ...

• #### 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 ...
• #### Modelling Holling type II functional response in deterministic and stochastic food chain models with mass conservation ﻿

(2022-03-01)
The Rosenzweig-MacArthur predator-prey model is the building block in modeling food chain, food webs and ecosystems. There are a number of hidden assumptions involved in the derivation. For instance the prey population ...
• #### 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 ﻿
