From individual behaviour to an evaluation of the collective evolution of crowds along footbridges
Luca Bruno, Alessandro Corbetta, Andrea Tosin
This paper proposes a crowd dynamic macroscopic model grounded on microscopic phenomenological observations which are upscaled by means of a formal mathematical procedure. The actu…
Reaction Spreading on Graphs
R. Burioni, S. Chibbaro, D. Vergni +1
We study reaction-diffusion processes on graphs through an extension of the standard reaction-diffusion equation starting from first principles. We focus on reaction spreading, i.e…
Semiflexible polymers under external fields confined to two dimensions
A. Lamura, R. G. Winkler
The non-equilibrium structural and dynamical properties of semiflexible polymers confined to two dimensions are investigated by molecular dynamics simulations. Three different scen…
Rare Mutations in Evolutionary Dynamics
Anna Lisa Amadori, Antonella Calzolari, Roberto Natalini +1
In this paper we study the effect of rare mutations, driven by a marked point process, on the evolutionary behavior of a population. We derive a Kolmogorov equation describing the…
A fully-discrete-state kinetic theory approach to modeling vehicular traffic
Luisa Fermo, Andrea Tosin
This paper presents a new mathematical model of vehicular traffic, based on the methods of the generalized kinetic theory, in which the space of microscopic states (position and ve…
Gravitational radiation reaction along general orbits in the effective one-body formalism
Donato Bini, Thibault Damour
We derive the gravitational radiation-reaction force modifying the Effective One Body (EOB) description of the conservative dynamics of binary systems. Our result is applicable to…
A generalized telegraph process with velocity driven by random trials
Irene Crimaldi, Antonio Di Crescenzo, Antonella Iuliano +1
We consider a random trial-based telegraph process, which describes a motion on the real line with two constant velocities along opposite directions. At each epoch of the underlyin…
Time Asymptotic High Order Schemes for Dissipative BGK Hyperbolic Systems
Denise Aregba-Driollet, Maya Briani, Roberto Natalini
We introduce a new class of finite differences schemes to approximate one dimensional dissipative semilinear hyperbolic systems with a BGK structure. Using precise analytical time-…
A hyperbolic model of chemotaxis on a network: a numerical study
Gabriella Bretti, Roberto Natalini, Magali Ribot
In this paper we deal with a semilinear hyperbolic chemotaxis model in one space dimension evolving on a network, with suitable transmission conditions at nodes. This framework is…
Kernel density estimation via diffusion and the complex exponentials approximation problem
Piero Barone
A kernel method is proposed to estimate the condensed density of the generalized eigenvalues of pencils of Hankel matrices whose elements have a joint noncentral Gaussian distribut…
Flow through randomly curved manifolds
M. Mendoza, S. Succi, H. J. Herrmann
We have found that the relation between the flow through campylotic (generically curved) media, consisting of randomly located curvature perturbations, and the average Ricci scalar…
Single to Double Hump Transition in the Equilibrium Distribution Function of Relativistic Particles
M. Mendoza, N. A. M. Araújo, S. Succi +1
We unveil a transition from single peaked to bimodal velocity distribution in a relativistic fluid under increasing temperature, in contrast with a non-relativistic gas, where only…
How can macroscopic models reveal self-organization in traffic flow?
Emiliano Cristiani, Benedetto Piccoli, Andrea Tosin
In this paper we propose a new modeling technique for vehicular traffic flow, designed for capturing at a macroscopic level some effects, due to the microscopic granularity of the…
Spacetime Splitting, Admissible Coordinates and Causality
D. Bini, C. Chicone, B. Mashhoon
To confront relativity theory with observation, it is necessary to split spacetime into its temporal and spatial components. The (1+3) timelike threading approach involves restrict…
Klein Tunneling in the presence of random impurities
S. Palpacelli, M. Mendoza, H. J. Herrmann +1
In this paper, we study Klein tunneling in random media. To this purpose, we simulate the propagation of a relativistic Gaussian wavepacket through a graphene sample with randomly…
Invasions in heterogeneous habitats in the presence of advection
Davide Vergni, Sandro Iannaccone, Stefano Berti +1
We investigate invasions from a biological reservoir to an initially empty, heterogeneous habitat in the presence of advection. The habitat consists of a periodic alternation of fa…
Isotropic discrete Laplacian operators from lattice hydrodynamics
Sumesh P. Thampi, Santosh Ansumali, Ronojoy Adhikari +1
We show that discrete schemes developed for lattice hydrodynamics provide an elegant and physically transparent way of deriving Laplacians with isotropic discretisation error. Isot…
Small, medium and large shock waves for non-equilibrium radiation hydrodynamic
Corrado Mascia
We examine the existence of shock profiles for a hyperbolic-elliptic system arising in radiation hydrodynamics. The algebraic-differential system for the wave profile is reduced to…
Effective action approach to higher-order relativistic tidal interactions in binary systems and their effective one body description
Donato Bini, Thibault Damour, Guillaume Faye
The gravitational-wave signal from inspiralling neutron-star--neutron-star (or black-hole--neutron-star) binaries will be influenced by tidal coupling in the system. An important s…
Pre-Turbulent Regimes in Graphene Flows
M. Mendoza, H. J. Herrmann, S. Succi
We provide numerical evidence that electronic pre-turbulent phenomena in graphene could be observed, under current experimental conditions, through detectable current fluctuations,…
On the condensed density of the zeros of the Cauchy transform of a complex atomic random measure with Gaussian moments
Piero Barone
An atomic random complex measure defined on the unit disk with Normally distributed moments is considered. An approximation to the distribution of the zeros of its Cauchy transform…
