The Remodeling of Fiber Distributions in Biological Tissues: Rotation without Rotation
Christian Cherubini, Marcello Vasta, Filippo Recrosi +1
Collagen remodeling in living tissues exhibits anisotropic orientation patterns commonly described by Von Mises distributions, yet the physical origin of such nonequilibrium organi…
Impact of Electric Spatially Discordant Alternans on Cardiac Magnetic Field
Martina Nicoletti, Anna Crispino, Alessandro Loppini +4
Spatially discordant alternans (SDA) play a crucial role in cardiac arrhythmogenesis by creating steep repolarization gradients facilitating conduction block and reentry. While tra…
Magnetic Signature of Thermo-Electric Cardiac Dynamics
Anna Crispino, Martina Nicoletti, Alessandro Loppini +4
Developing new methods for predicting electromagnetic instabilities in cardiac activity is of primary importance. However, we still need a comprehensive view of the heart's magneti…
Phase field modelling and simulation of damage occurring in human vertebra after screws fixation procedure
Deison Preve, Pietro Lenarda, Daniele Bianchi +1
The present endeavor numerically exploits the use of a phase-field model to simulate and investigate fracture patterns, deformation mechanisms, damage, and mechanical responses in…
A numerical model of the human cornea accounting for the fiber-distributed collagen microstructure
Maria Laura De Bellis, Marcello Vasta, Alessio Gizzi +1
We present a fiber-distributed model of the reinforcing collagen of the human cornea. The model describes the basic connections between the components of the tissue by defining an…
An orthotropic electro-viscoelastic model for the heart with stress-assisted diffusion
Adrienne Propp, Alessio Gizzi, Francesc Levrero-Florencio +1
We propose and analyse the properties of a new class of models for the electromechanics of cardiac tissue. The set of governing equations consists of nonlinear elasticity using a v…
Spatiotemporal correlation uncovers fractional scaling in cardiac tissue
Alessandro Loppini, Alessio Gizzi, Christian Cherubini +3
Complex spatiotemporal patterns of action potential duration have been shown to occur in many mammalian hearts due to a period-doubling bifurcation that develops with increasing fr…
Competing mechanisms of stress-assisted diffusivity and stretch-activated currents in cardiac electromechanics
A. Loppini, A. Gizzi, R. Ruiz Baier +3
We numerically investigate the role of mechanical stress in modifying the conductivity properties of the cardiac tissue and its impact in computational models for cardiac electrome…
Modelling thermo-electro-mechanical effects in orthotropic cardiac tissue
Ricardo Ruiz Baier, Alessio Gizzi, Alessandro Loppini +2
In this paper we introduce a new mathematical model for the active contraction of cardiac muscle, featuring different thermo-electric and nonlinear conductivity properties. The pas…
A modeling framework for contact, adhesion and mechano-transduction between excitable deformable cells
Pietro Lenarda, Alessio Gizzi, Marco Paggi
Cardiac myocytes are the fundamental cells composing the heart muscle. The propagation of electric signals and chemical quantities through them is responsible for their nonlinear c…
Nonlinear diffusion & thermo-electric coupling in a two-variable model of cardiac action potential
A. Gizzi, A. Loppini, R. Ruiz-Baier +8
This work reports the results of the theoretical investigation of nonlinear dynamics and spiral wave breakup in a generalized two-variable model of cardiac action potential account…
A note on stress-driven anisotropic diffusion and its role in active deformable media
Christian Cherubini, Simonetta Filippi, Alessio Gizzi +1
We propose a new model to describe diffusion processes within active deformable media. Our general theoretical framework is based on physical and mathematical considerations, and i…
On the coherent behavior of pancreatic beta cell clusters
Alessandro Loppini, Antonio Capolupo, Christian Cherubini +4
Beta cells in pancreas represent an example of coupled biological oscillators which via communication pathways, are able to synchronize their electrical activity, giving rise to pu…
