High-order post-Newtonian contributions to the two-body gravitational interaction potential from analytical gravitational self-force calculations
Donato Bini, Thibault Damour
We extend the analytical determination of the main radial potential describing (within the effective one-body formalism) the gravitational interaction of two bodies beyond the 4th…
Deviation of quadrupolar bodies from geodesic motion in a Kerr spacetime
Donato Bini, Andrea Geralico
The deviation from geodesic motion of the world line of an extended body endowed with multipolar structure up to the mass quadrupole moment is studied in the Kerr background accord…
A hybrid mathematical model for self-organizing cell migration in the zebrafish lateral line
Ezio Di Costanzo, Roberto Natalini, Luigi Preziosi
In this paper we propose a "discrete in continuous" mathematical model for the morphogenesis of the posterior lateral line system in zebrafishes. Our model follows closely the resu…
Formal analogy between the Dirac equation in its Majorana form and the discrete-velocity version of the Boltzmann kinetic equation
F. Fillion-Gourdeau, H. J. Herrmann, M. Mendoza +2
We point out a formal analogy between the Dirac equation in Majorana form and the discrete-velocity version of the Boltzmann kinetic equation. By a systematic analysis based on the…
An easy-to-use algorithm for simulating traffic flow on networks: numerical experiments
Gabriella Bretti, Maya Briani, Emiliano Cristiani
In this paper we propose a Godunov-based discretization of a hyperbolic system of conservation laws with discontinuous flux, modeling vehicular flow on a network. Each equation des…
Relativistic effects on the Richtmyer-Meshkov instability
F. Mohseni, M. Mendoza, S. Succi +1
Theoretical and numerical analysis of the relativistic effects on the Richtmyer-Meshkov (RM) instability reveals new and potentially very useful effects. We find that, in contrast…
On an inverse problem for scalar conservation laws
Helge Holden, Fabio Simone Priuli, Nils Henrik Risebro
We study in what sense one can determine the function in the scalar hyperbolic conservation law by observing the solution $u(t,\dott)$ of the Cauchy p…
The Z-index: A geometric representation of productivity and impact which accounts for information in the entire rank-citation profile
Alexander M. Petersen, Sauro Succi
We present a simple generalization of Hirsch's h-index, Z = \sqrt{h^{2}+C}/\sqrt{5}, where C is the total number of citations. Z is aimed at correcting the potentially excessive pe…
Macroscopic modeling and simulations of room evacuation
Monika Twarogowska, Paola Goatin, Regis Duvigneau
We analyze numerically two macroscopic models of crowd dynamics: the classical Hughes model and the second order model being an extension to pedestrian motion of the Payne-Whitham…
GPU peer-to-peer techniques applied to a cluster interconnect
Roberto Ammendola, Massimo Bernaschi, Andrea Biagioni +11
Modern GPUs support special protocols to exchange data directly across the PCI Express bus. While these protocols could be used to reduce GPU data transmission times, basically by…
A hybrid approach for the implementation of the Heston model
Maya Briani, Lucia Caramellino, Antonino Zanette
We propose a hybrid tree-finite difference method in order to approximate the Heston model. We prove the convergence by embedding the procedure in a bivariate Markov chain and we s…
Spinodal decomposition in homogeneous and isotropic turbulence
Prasad Perlekar, Roberto Benzi, Herman J. H. Clercx +2
We study the competition between domain coarsening in a symmetric binary mixtures below the critical temperature and turbulent fluctuations. We find that the coarsening process is…
Solar System constraints to nonminimally coupled gravity
Orfeu Bertolami, Riccardo March, Jorge Páramos
We extend the analysis of Chiba, Smith and Erickcek \cite{CSE} of Solar System constraints on gravity to a class of nonminimally coupled (NMC) theories of gravity. These gen…
Comparing first order microscopic and macroscopic crowd models for an increasing number of massive agents
Alessandro Corbetta, Andrea Tosin
In this paper a comparison between first order microscopic and macroscopic differential models of crowd dynamics is established for an increasing number of pedestrians. The nov…
Analytical determination of the two-body gravitational interaction potential at the 4th post-Newtonian approximation
Donato Bini, Thibault Damour
We complete the analytical determination, at the 4th post-Newtonian approximation, of the main radial potential describing the gravitational interaction of two bodies within the ef…
Fundamental diagrams for kinetic equations of traffic flow
Luisa Fermo, Andrea Tosin
In this paper we investigate the ability of some recently introduced discrete kinetic models of vehicular traffic to catch, in their large time behavior, typical features of theore…
Kinetic Formulation of the Kohn-Sham Equations for ab initio Electronic Structure Calculations
M. Mendoza, S. Succi, H. J. Herrmann
We introduce a new approach to density functional theory based on kinetic theory, showing that the Kohn-Sham equations can be derived as a macroscopic limit of a suitable Boltzmann…
CUDA Leaks: Information Leakage in GPU Architectures
Roberto Di Pietro, Flavio Lombardi, Antonio Villani
Graphics Processing Units (GPUs) are deployed on most present server, desktop, and even mobile platforms. Nowadays, a growing number of applications leverage the high parallelism o…
Rheological properties of soft-glassy flows from hydro-kinetic simulations
R. Benzi, M. Bernaschi, M. Sbragaglia +1
Based on numerical simulations of a lattice kinetic model for soft-glassy materials, we characterize the global rheology of a dense emulsion-like system, under three representative…

Marcello Sega, Mauro Sbragaglia, Luca Biferale +1
We performed non-equilibrium Molecular Dynamics simulations of water flow in nano-channels with the aim of discriminating {\it static} from {\it dynamic} contributions of the solid…
