In this paper we propose a LWR-like model for traffic flow on
networks which allows to track several groups of drivers, each of them being
characterized only by their destination in the network. The path actually
followed to reach the destination is not assigned a priori, and can be chosen
by the… |

Agent-based models, an emerging paradigm of simulation of complex
systems, appear very suitable to parallel processing. However, during
the parallelization of a simulator of financial markets, we found that
some features of these codes highlight non-trivial issues of the
present hardware/software… |

The crack density within a fault's damage zone is thought to vary as seismic rupture is approached, as well as in the postseismic period. Moreover, external stress loads, seasonal or tidal, may also change the crack density in rocks, and all such processes can leave detectable signatures on seismic… |

Omics data and computational approaches are today providing a key to disentangle the complex architecture of living systems. The integration and analysis of data of different nature allows to extract meaningful representations of signaling pathways and protein interactions networks, helpful in… |

Continuing our analytic computation of the first-order self-force contribution to the "geodetic" spin precession frequency of a small spinning body orbiting a large (nonspinning) body, we provide the exact expressions of the 10 and 10.5 post-Newtonian terms. We also introduce a new approach to the… |

We present a numerical study of the micro-dynamical roots of dissipation in two colliding mesoscopic clouds of point-like fermions as a function of the scattering length and of temperature approaching full quantum degeneracy. This study, which is motivated by current experiments on ultracold… |

We present a new multistage method to study the N-Methyl-D-Aspartate (NMDA) neuroreceptor starting from the reconstruction of its crystallographic structure. Thanks to the combination of Homology Modelling, Molecular Dynamics and Lattice Boltzmann simulations, we analyse the allosteric transition… |

Lyapunov exponents of heavy particles and tracers advected by homogeneous and isotropic turbulent flows are investigated by means of direct numerical simulations. For large values of the Stokes number, the main effect of inertia is to reduce the chaoticity with respect to fluid tracers. Conversely… |

We evaluate a mathematical model of the predator-prey population dynamics in a fragmented habitat where both migration processes between habitat patches and prey control policies are taken into account. The considered system is examined by applying the aggregation method and different dynamical… |

The behavior of charged spinning test particles moving along circular orbits in the equatorial plane of the Reissner{Nordstrom space{time is studied in the framework of the Dixon Souriau model completed with standard choices of supplementary conditions.
The gravitomagnetic "clock effect," i.e. the… |
