Stationary axisymmetric spacetimes containing a pair of oppositely
rotating periodically intersecting circular geodesics allow us to study
the various so-called 'clock effects' by comparing either observer or
geodesic proper time periods of orbital circuits defined by the observer
or the… |

This paper investigates the model for pedestrian flow firstly proposed in [Cristiani, Priuli, and Tosin, SIAM J. Appl. Math., 75:605-629, 2015]. The model assumes that each individual in the crowd moves in a known domain, aiming at minimizing a given cost functional. Both the pedestrian dynamics… |

The aim of this paper is to describe how ground-based radar interferometry can provide displacement measurements of earth dam surfaces and of vibration frequencies of its main concrete infrastructures. In many cases, dams were built many decades ago and, at that time, were not equipped with in situ… |

We propose a mesoscopic model of binary fluid mixtures with tunable viscosity ratio based on a two-range pseudopotential lattice Boltzmann method, for the simulation of soft flowing systems. In addition to the short-range repulsive interaction between species in the classical single-range model, a… |

A pointwise stability result for the equation ut = ?F (u) in the exterior of a sphere is
obtained, in the class of perturbations which a-priori are allowed to grow at least polinomially at
large spatial distances. |

We derive an asymptotic equation that describes the propagation
of weakly nonlinear surface waves on a tangential discontinuity
in incompressible magnetohydrodynamics. The equation is similar
to, but simpler than, previously derived asymptotic
equations for weakly nonlinear Rayleigh waves in… |

We point out a formal analogy between lattice kinetic propagators and Haldane-Wu fractional statistics. The analogy could be used to compute the partition function of fractional quantum systems by solving a corresponding lattice kinetic equation for classical dissipative flowing syst erns.… |
