Lattice Boltzmann scheme for relativistic fluids
M. Mendoza, B. Boghosian, H. J. Herrmann +1
A Lattice Boltzmann formulation for relativistic fluids is presented and numerically verified through quantitative comparison with recent hydrodynamic simulations of relativistic s…
Initial/boundary-value problems of tumor growth within a host tissue
Andrea Tosin
This paper concerns multiphase models of tumor growth in interaction with a surrounding tissue, taking into account also the interplay with diffusible nutrients feeding the cells.…
Dixon's extended bodies and impulsive gravitational waves
Donato Bini, Pierluigi Fortini, Andrea Geralico +1
The "reaction" of an extended body to the passage of an exact plane gravitational wave is discussed following Dixon's model. The analysis performed shows several general features,…
Dixon's extended bodies and weak gravitational waves
Donato Bini, Christian Cherubini, Andrea Geralico +1
General relativity considers Dixon's theory as the standard theory to deal with the motion of extended bodies in a given gravitational background. We discuss here the features of t…
Quadrupole effects on the motion of extended bodies in Schwarzschild spacetime
Donato Bini, Pierluigi Fortini, Andrea Geralico +1
The motion of an extended body up to the quadrupolar structure is studied in the Schwarzschild background following Dixon's model and within certain restrictions (constant frame co…
Extended bodies with quadrupole moment interacting with gravitational monopoles: reciprocity relations
Donato Bini, Christian Cherubini, Simonetta Filippi +1
An exact solution of Einstein's equations representing the static gravitational field of a quasi-spherical source endowed with both mass and mass quadrupole moment is considered. I…
Decay of Positive Waves for Hyperbolic Systems of Balance Laws
Paola Goatin, Laurent Gosse
We prove Ole\u ınik-type decay estimates for entropy solutions of strictly hyperbolic systems of balance laws built out of a wave-front tracking procedure inside which…
Generalized Kerr spacetime with an arbitrary mass quadrupole moment: geometric properties vs particle motion
Donato Bini, Andrea Geralico, Orlando Luongo +1
An exact solution of Einstein's field equations in empty space first found in 1985 by Quevedo and Mashhoon is analyzed in detail. This solution generalizes Kerr spacetime to includ…
Mesoscopic lattice Boltzmann modeling of soft-glassy systems: theory and simulations
R. Benzi, M. Sbragaglia, S. Succi +2
A multi-component lattice Boltzmann model recently introduced (R. Benzi et al. Phys. Rev. Lett 102, 026002 (2009)) to describe some dynamical behaviors of soft-flowing materials is…
Gossip consensus algorithms via quantized communication
Ruggero Carli, Fabio Fagnani, Paolo Frasca +1
This paper considers the average consensus problem on a network of digital links, and proposes a set of algorithms based on pairwise ''gossip'' communications and updates. We study…
Nanoflows through disordered media: a joint Lattice Boltzmann and Molecular Dynamics investigation
J. Russo, J. Horbach, F. Sciortino +1
We investigate nanoflows through dilute disordered media by means of joint lattice Boltzmann (LB) and molecular dynamics (MD) simulations -- when the size of the obstacles is compa…
Noisy Independent Factor Analysis Model for Density Estimation and Classification
Umberto Amato, Anestis Antoniadis, Alexander Samarov +1
We consider the problem of multivariate density estimation when the unknown density is assumed to follow a particular form of dimensionality reduction, a noisy independent factor a…
A black box method for solving the complex exponentials approximation problem
Piero Barone
A common problem, arising in many different applied contexts, consists in estimating the number of exponentially damped sinusoids whose weighted sum best fits a finite set of noisy…
Turbulent pair dispersion of inertial particles
J. Bec, L. Biferale, A. S. Lanotte +2
The relative dispersion of pairs of inertial particles in incompressible, homogeneous, and isotropic turbulence is studied by means of direct numerical simulations at two values of…
Quantized biopolymer translocation through nanopores: departure from simple scaling
Simone Melchionna, Massimo Bernaschi, Maria Fyta +2
We discuss multiscale simulations of long biopolymer translocation through wide nanopores that can accommodate multiple polymer strands. The simulations provide clear evidence of f…
Detection of Gaussian signals via hexagonal sensor networks
Paolo Frasca, Paolo Mason, Benedetto Piccoli
This paper considers a special case of the problem of identifying a static scalar signal, depending on the location, using a planar network of sensors in a distributed fashion. Mot…
Continuum Free-Energy formulation for a class of Lattice Boltzmann multiphase models
M. Sbragaglia, H. Chen, X. Shan +1
It is shown that the Shan-Chen (SC) model for non-ideal lattice fluids can be made compliant with a pseudo free-energy principle by simple addition of a gradient force, whose expre…
Numerical simulation of conformational variability in biopolymer translocation through wide nanopores
Maria Fyta, Simone Melchionna, Massimo Bernaschi +2
Numerical results on the translocation of long biopolymers through mid-sized and wide pores are presented. The simulations are based on a novel methodology which couples molecular…
Lattice Boltzmann method with self-consistent thermo-hydrodynamic equilibria
M. Sbragaglia, R. Benzi, L. Biferale +3
Lattice kinetic equations incorporating the effects of external/internal force fields via a shift of the local fields in the local equilibria, are placed within the framework of co…
Hydrokinetic simulations of nanoscopic precursor films in rough channels
S. Chibbaro, L. Biferale, K. Binder +4
We report on simulations of capillary filling of high-wetting fluids in nano-channels with and without obstacles. We use atomistic (molecular dynamics) and hydrokinetic (lattice-Bo…
