Spectral analysis of a blocktriangular preconditioner for the bidomain system in electrocardiology
(20121231)In this paper we analyze in detail the spectral properties of the blocktriangular preconditioner introduced by GerardoGiorda et al. [J. Comput. Phys., 228 (2009), pp. 36253639] for the Bidomain system in nonsymmetric ... 
Numerical simulation of a susceptibleexposedinfectious spacecontinuous model for the spread of rabies in raccoons across a realistic landscape
(20131231)We introduce a numerical model for the spread of a lethal infectious disease in wildlife. The reference model is a SusceptibleExposedInfectious system where the spatial component of the dynamics is modelled by a diffusion ... 
Optimized schwarz methods for the bidomain system in electrocardiology
(20131231)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 ... 
Structuring targeted surveillance for monitoring disease emergence by mapping observational data onto ecological process
(20131231)An efficient surveillance system is a crucial factor in identifying, monitoring and tackling outbreaks of infectious diseases. Scarcity of data and limited amounts of economic resources require a targeted effort from public ...

(20141231)[No abstract available] 
Incorporating landscape heterogeneities in the spread of an epidemics in wildlife
(20141231)One of the main difficulties in the modeling and numerical simulation of the spread of an infectious disease in wildlife resides in properly taking into account the heterogeneities of the landscape. Forests, plains and ... 
Largescale simulations of synthetic markets
(20151008)Highfrequency trading has been experiencing an increase of interest both for practical purposes within nancial institutions and within academic research; recently, the UK Government O ce for Science reviewed the state ... 
Geometry shapes propagation: Assessing the presence and absence of cortical symmetries through a computational model of cortical spreading depression
(20151231)Cortical spreading depression (CSD), a depolarization wave which originates in the visual cortex and travels toward the frontal lobe, has been suggested to be one neural correlate of aura migraine. To the date, little is ... 
Lagged and instantaneous dynamical influences related to brain structural connectivity
(20151231)Contemporary neuroimaging methods can shed light on the basis of human neural and cognitive specializations, with important implications for neuroscience and medicine. Indeed, different MRI acquisitions provide different ... 
Information Flow between RestingState Networks
(20151231)The resting brain dynamics selforganize into a finite number of correlated patterns known as restingstate networks (RSNs). It is well known that techniques such as independent component analysis can separate the brain ... 
Functional connectivity of EEG signals under laser stimulation in migraine
(20151231)In previous studies, migraine patients showed abnormalities in painrelated evoked responses, as reduced habituation to repetitive stimulation. In this study, we aimed to apply a novel analysis of EEG bands synchronization ... 
Longitudinal variations of brain functional connectivity: A case report study based on a mouse model of epilepsy
(20151231)Brain Functional Connectivity (FC) quantifies statistical dependencies between areas of the brain. FC has been widely used to address altered function of brain circuits in control conditions compared to different pathological ... 
Extreme brain events: Higherorder statistics of brain resting activity and its relation with structural connectivity
(20151231)The brain exhibits a wide variety of spatiotemporal patterns of neuronal activity recorded using functional magnetic resonance imaging as the socalled bloodoxygenatedleveldependent (BOLD) signal. An active area of work ... 
Parallelizing the KolmogorovFokkerPlanck Equation
(20151231)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 FokkerPlanck equation describing the ... 
Computational modeling of openirrigated electrodes for radiofrequency cardiac ablation including blood motionsaline flow interaction
(2016)Radiofrequency catheter ablation (RFCA) is a routine treatment for cardiac arrhythmias. During RFCA, the electrodetissue interface temperature should be kept below 80°C to avoid thrombus formation. Openirrigated electrodes ... 
Computational Model for Prediction of the Occurrence of Steam Pops during Irrigated Radiofrequency Catheter Ablation
(2016)Radiofrequency catheter ablation (RFCA) is a curative treatment for cardiac arrhythmias. Although globally a pretty safe procedure, it may present some risk. Steam pop is a serious complication that can occur during RFCA ... 
An introduction to mathematical and numerical modeling in heart electrophysiology
(2016)The electrical activation of the heart is the biological process that regulates the contraction of the cardiac muscle, allowing it to pump blood to the whole body. In physiological conditions, the pacemaker cells of the ... 
Comparative analysis of different methods of modeling the thermal effect of circulating blood flow during RF cardiac ablation
(20160101)Our aim was to compare the different methods of modeling the effect of circulating blood flow on the thermal lesion dimensions created by radio frequency (RF) cardiac ablation and on the maximum blood temperature. Computational ... 
A computational model of openirrigated electrode for endocardial RF catheter ablation
(20160101)Radiofrequency catheter ablation (RFCA) is an important curative treatment for cardiac arrhythmias. However, during RFCA thrombus formation can occur when the electrodetissue interface temperature exceeds 80Â°C. Openirrigated ...
