Stirring, mixing, growing: microscale processes change larger scale phytoplankton dynamics
Francesco Paparella, Marcello Vichi
The quantitative description of marine systems is constrained by a major issue of scale separation: most marine biochemical processes occur at sub-centimeter scales, while the cont…
Lagrangian Numerical Methods for Ocean Biogeochemical Simulations
Francesco Paparella, Marina Popolizio
We propose two closely--related Lagrangian numerical methods for the simulation of physical processes involving advection, reaction and diffusion. The methods are intended to be us…
Biological control of the chestnut gall wasp with \emph{T. sinensis}: a mathematical model
Francesco Paparella, Chiara Ferracini, Alessandro Portaluri +2
The Asian chestnut gall wasp \emph{Dryocosmus kuriphilus}, native of China, has become a pest when it appeared in Japan, Korea, and the United States. In Europe it was first found…
A Mathematical Model of Flavescence Dorée Epidemiology
Federico Lessio, Alessandro Portaluri, Francesco Paparella +1
Flavescence dorée (FD) is a disease of grapevine transmitted by an insect vector, Ball. At present, no prophylaxis exists, so mandatory control procedures (…
Global dynamics of stationary, dihedral, nearly-parallel vortex filaments
Francesco Paparella, Alessandro Portaluri
The goal of this paper is to give a detailed analytical description of the global dynamics of N points interacting through the singular logarithmic potential and subject to the fol…
Global dynamics under a weak potential on a sphere
Roberto Castelli, Francesco Paparella, Alessandro Portaluri
We give a detailed analytical description of the global dynamics of a point mass moving on a sphere under the action of a logarithmic potential. After performing a McGehee-type blo…
On the Allometric Scaling of Resource Intake Under Limiting Conditions
Alberto Basset, Francesco Paparella, Francesco Cozzoli
Individual resource intake rates are known to depend on both individual body size and resource availability. Here, we have developed a model to integrate these two drivers, account…
Non-Gaussian buoyancy statistics in fingering convection
Jost von Hardenberg, Francesco Paparella
We examine the statistics of active scalar fluctuations in high-Rayleigh number fingering convection with high-resolution three-dimensional numerical experiments. The one-point dis…
On the Stopping Time of a Bouncing Ball
Anna Maria Cherubini, Giorgio Metafune, Francesco Paparella
We study a simple model of a bouncing ball that takes explicitely into account the elastic deformability of the body and the energy dissipation due to internal friction. We show th…
Filling Gaps in Chaotic Time Series
Francesco Paparella
We propose a method for filling arbitrarily wide gaps in deterministic time series. Crucial to the method is the ability to apply Takens' theorem in order to reconstruct the dynami…
Shear and Mixing in Oscillatory Doubly Diffusive Convection
Francesco Paparella, Edward A. Spiegel, Suzanne Talon
To investigate the mechanism of mixing in oscillatory doubly diffusive (ODD) convection, we truncate the horizontal modal expansion of the Boussinesq equations to obtain a simplifi…
Slow and fast dynamics in coupled systems: A time series analysis view
G. Boffetta, A. Crisanti, F. Paparella +2
We study the dynamics of systems with different time scales, when access only to the slow variables is allowed. We use the concept of Finite Size Lyapunov Exponent (FSLE) and consi…
