Different Impact of Heart Rate Variability in the Deep Cerebral and Central Hemodynamics at Rest: An in silico Investigation
Stefania Scarsoglio, Luca Ridolfi
Heart rate variability (HRV), defined as the variability between consecutive heartbeats, is a surrogate measure of cardiac vagal tone. It is widely accepted that a decreased HRV is…
Large-to-small scale frequency modulation analysis in wall-bounded turbulence via visibility networks
Giovanni Iacobello, Luca Ridolfi, Stefania Scarsoglio
Scale interaction is studied in wall-bounded turbulence by focusing on the frequency modulation (FM) mechanism of large scales on small scale velocity fluctuations. Differently fro…

Experimental investigation of vertical turbulent transport of a passive scalar in a boundary layer: statistics and visibility graph analysis
Giovanni Iacobello, Massimo Marro, Luca Ridolfi +2
The dynamics of a passive scalar plume in a turbulent boundary layer is experimentally investigated via vertical turbulent transport time-series. Data are acquired in a rough-wall…
Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events
Andrea Saglietto, Stefania Scarsoglio, Luca Ridolfi +2
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occ…
Lagrangian network analysis of turbulent mixing
Giovanni Iacobello, Stefania Scarsoglio, J. G. M. Kuerten +1
A temporal complex network-based approach is proposed as a novel formulation to investigate turbulent mixing from a Lagrangian viewpoint. By exploiting a spatial proximity criterio…
Effects of atrial fibrillation on the arterial fluid dynamics: a modelling perspective
Stefania Scarsoglio, Caterina Gallo, Luca Ridolfi
Atrial fibrillation (AF) is the most common form of arrhythmia with accelerated and irregular heart rate (HR), leading to both heart failure and stroke and being responsible for an…

Computational fluid dynamics modelling of left valvular heart diseases during atrial fibrillation
Stefania Scarsoglio, Andrea Saglietto, Fiorenzo Gaita +2
Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. Th…
Transient cerebral hypoperfusion and hypertensive events during atrial fibrillation: a plausible mechanism for cognitive impairment
Matteo Anselmino, Stefania Scarsoglio, Andrea Saglietto +2
Atrial fibrillation (AF) is associated with an increased risk of dementia and cognitive decline, independent of strokes. Several mechanisms have been proposed to explain this assoc…
Climate Dynamics: A Network-Based Approach for the Analysis of Global Precipitation
Stefania Scarsoglio, Francesco Laio, Luca Ridolfi
Precipitation is one of the most important meteorological variables for defining the climate dynamics, but the spatial patterns of precipitation have not been fully investigated ye…
Spatial pattern formation induced by Gaussian white noise
Stefania Scarsoglio, Francesco Laio, Paolo D'Odorico +1
The ability of Gaussian noise to induce ordered states in dynamical systems is here presented in an overview of the main stochastic mechanisms able to generate spatial patterns. Th…
Spatio-temporal stochastic resonance induces patterns in wetland vegetation dynamics
Stefania Scarsoglio, Paolo D'Odorico, Francesco Laio +1

New observations in transient hydrodynamic perturbations. Frequency jumps, intermediate term and spot formation
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
Sheared incompressible flows are usually considered non-dispersive media. As a consequence, the frequency evolution in transients has received much less attention than the wave ene…
Kolmogorov scaling bridges linear hydrodynamic stability and turbulence
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
The way in which kinetic energy is distributed over the multiplicity of inertial (intermediate) scales is a fundamental feature of turbulence. According to Kolmogorov's 1941 theory…
Pre-unstable set of multiple transient three-dimensional perturbation waves and the associated turbulent state in a shear flow
Stefania Scarsoglio, Daniela Tordella
In order to understand whether, and to what extent, spectral representation can effectively highlight the nonlinear interaction among different scales, it is necessary to consider…
