DSMC-LBM mapping scheme for rarefied and non-rarefied gas flows
G. Di Staso, H. J. H Clercx, S. Succi +1
We present the formulation of a kinetic mapping scheme between the Direct Simulation Monte Carlo (DSMC) and the Lattice Boltzmann Method (LBM) which is at the basis of the hybrid m…
A discrete in continuous mathematical model of cardiac progenitor cells formation and growth as spheroid clusters (Cardiospheres)
Ezio Di Costanzo, Alessandro Giacomello, Elisa Messina +5
We propose a discrete in continuous mathematical model describing the in vitro growth process of biophsy-derived mammalian cardiac progenitor cells growing as clusters in the form…
On the long-time behavior of a continuous duopoly model with constant conjectural variation
Isabella Torcicollo
The paper concerns a continuous model governed by a ODE system originated by a discrete duopoly model with bounded rationality, based on constant conjectural variation. The ultimat…
Handling obstacles in pedestrian simulations: models and optimization
Emiliano Cristiani, Daniele Peri
In this paper we are concerned with the simulation of crowds in built environments, where obstacles play a role in the dynamics and in the interactions among pedestrians. First of…
Poiseuille flow in curved spaces
J. -D. Debus, M. Mendoza, S. Succi +1
We investigate Poiseuille channel flow through intrinsically curved media, equipped with localized metric perturbations. To this end, we study the flux of a fluid driven through th…
Confirming and improving post-Newtonian and effective-one-body results from self-force computations along eccentric orbits around a Schwarzschild black hole
Donato Bini, Thibault Damour, Andrea Geralico
We analytically compute, through the six-and-a-half post-Newtonian order, the second-order-in-eccentricity piece of the Detweiler-Barack-Sago gauge-invariant redshift function for…
Dynamic mesh refinement for discrete models of jet electro-hydrodynamics
Marco Lauricella, Giuseppe Pontrelli, Dario Pisignano +1
Nowadays, several models of unidimensional fluid jets exploit discrete element methods. In some cases, as for models aiming at describing the electrospinning nanofabrication proces…
Analysis of a heterogeneous kinetic model for traffic flow
Gabriella Puppo, Matteo Semplice, Andrea Tosin +1
In this work we extend a recent kinetic traffic model to the case of more than one class of vehicles, each of which is characterized by few different microscopic features. We consi…
Orbital effects due to gravitational induction
Donato Bini, Lorenzo Iorio, Domenico Giordano
We study the motion of test particles in the metric of a localized and slowly rotating astronomical source, within the framework of linear gravitoelectromagnetism, grounded on a Po…
Spin-dependent two-body interactions from gravitational self-force computations
Donato Bini, Thibault Damour, Andrea Geralico
We analytically compute, through the eight-and-a-half post-Newtonian order and the fourth-order in spin, the gravitational self-force correction to Detweiler's gauge invariant reds…
Massless Dirac particles in the vacuum C-metric
Donato Bini, Eduardo Bittencourt, Andrea Geralico
We study the behavior of massless Dirac particles in the vacuum C-metric spacetime, representing the nonlinear superposition of the Schwarzschild black hole solution and the Rindle…
Slicing black hole spacetimes
Donato Bini, Eduardo Bittencourt, Andrea Geralico +1
A general framework is developed to investigate the properties of useful choices of stationary spacelike slicings of stationary spacetimes whose congruences of timelike orthogonal…
Short-lived lattice quasiparticles for strongly interacting fluids
M. Mendoza, S. Succi
It is shown that lattice kinetic theory based on short-lived quasiparticles proves very effective in simulating the complex dynamics of strongly interacting fluids (SIF). In partic…
Extinction dynamics of a discrete population in an oasis
Stefano Berti, Massimo Cencini, Davide Vergni +1
Understanding the conditions ensuring the persistence of a population is an issue of primary importance in population biology. The first theoretical approach to the problem dates b…
JETSPIN: a specific-purpose open-source software for simulations of nanofiber electrospinning
Marco Lauricella, Giuseppe Pontrelli, Ivan Coluzza +2
We present the open-source computer program JETSPIN, specifically designed to simulate the electrospinning process of nanofibers. Its capabilities are shown with proper reference t…
Lattice Boltzmann model for resistive relativistic magnetohydrodynamics
F. Mohseni, M. Mendoza, S. Succi +1
In this paper, we develop a lattice Boltzmann model for relativistic magnetohydrodynamics (MHD). Even though the model is derived for resistive MHD, it is shown that it is numerica…
The importance of chemical potential in the determination of water slip in nanochannels
Marcello Sega, Mauro Sbragaglia, Luca Biferale +1
We investigate the slip properties of water confined in graphite-like nano-channels by non-equilibrium molecular dynamics simulations, with the aim of identifying and analyze separ…
Cooling Effect of the Richtmyer-Meshkov Instability
F. Mohseni, M. Mendoza, S. Succi +1
We provide numerical evidence that the Richtmyer-Meshkov (RM) instability contributes to the cooling of a relativistic fluid. Due to the presence of jet particles traveling through…

M. Mendoza, H. J. Herrmann, S. Succi
Recently, a new connection between density functional theory and kinetic theory has been proposed. In particular, it was shown that the Kohn-Sham (KS) equations can be reformulated…

A. Alberico, G. di Blasio, F. Feo
We obtain a comparison result for solutions to nonlinear fully anisotropic elliptic problems by means of anisotropic symmetrization. As consequence we deduce a priori estimates for…
Exploring the relationship between the magnitudes of seismic events
Ilaria Spassiani, Giovanni Sebastiani
The distribution of the magnitudes of seismic events is generally assumed to be independent on past seismicity. However, by considering events in causal relation, for example mothe…
