SRv6 can provide hybrid cooperation between a centralized network controller and network nodes. IPv6 routers maintain
multi-hop ECMP-aware segments, whereas the controller establishes a source-routed path through the network. Since the
state of the flow is defined at the ingress to the network and… |

It is generally accepted that visual perception results from the activation of a feed-forward hierarchy of areas, leading to increasingly complex representations. Here we present evidence for a fundamental role of backward projections to the occipito-temporal region for understanding conceptual… |

In general relativity (GR), linearized gravitational waves propagating in empty Minkowski spacetime along a fixed spatial direction have the property that the wave front is the Euclidean plane. Beyond the linear regime, exact plane waves in GR have been studied theoretically for a long time and… |

We study the linear post-Newtonian approximation to general relativity
known as gravitoelectromagnetism (GEM); in particular, we examine the
similarities and differences between GEM and electrodynamics.
Notwithstanding some significant differences between them, we find that a special nonstationary… |

The problem of diurnal variation in surface emissivity over the Sahara Desert during non-raining days is studied and assessed with observations from the Infrared Atmospheric Sounding Interferometer (IASI). The analysis has been performed over a Sahara Desert dune target area during July 2010.… |

We propose a new iterative procedure to find the
best time for re-initialization of meta-heuristic algorithms to
solve combinatorial optimization problems. The sequence of
algorithm executions with different random inizializations evolves
at each iteration by either adding new independent… |

Many real life problems can be represented by an ordered sequence of digital images. At a given pixel a specific time course is observed which is morphologically related to the time courses at neighbor pixels. Useful information can be usually extracted from a set of such observations if we are… |

The equatorial motion of extended bodies in a Kerr spacetime is investigated in the framework of the Mathisson-Papapetrou-Dixon model, including the full set of effective components of the quadrupole tensor. The numerical integration of the associated equations shows the specific role of the mass… |

We show that the First-Passage-Time probability distribution of a Lévy time-changed Brownian motion with drift is solution of a time fractional advection-diffusion equation subject to initial and boundary conditions; the Caputo fractional derivative with respect to time is considered. We propose a… |
