• Incorporating landscape heterogeneities in the spread of an epidemics in wildlife ﻿

(Complex Systems; Control of Infectious Diseases, Extended Abstracts 2013. Ã lvaro Corral, Anna Deluca, Francesc Font-Clos, Pilar Guerrero, Andrei Korobeinikov, Francesco Massucci eds., Springer,.http://dx.doi.org/10.1007/978-3-319-08138-0_19", 2014-12-31)
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 ...
• Information Flow between Resting-State Networks ﻿

(Brain Connectivity, 2015-12-31)
The resting brain dynamics self-organize into a finite number of correlated patterns known as resting-state networks (RSNs). It is well known that techniques such as independent component analysis can separate the brain ...
• 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 ...
