In the application of Pad\'{e} methods to signal
processing a basic problem is to take into account the effect of
measurement noise on the computed approximants. Qualitative
deterministic noise models have been proposed which are consistent
with experimental results. In this paper the Pad\'{e}… |

Vitamin D has been proven to be a strong stimulator of mechanisms associated with the elimination of pathogens. Because of its recognized effectiveness against viral infections, during SARS-CoV-2 infection, the effects of Vitamin D supplementation have been the object of debate. This study aims to… |

We use high-resolution direct numerical simulations to study the anisotropic contents of a turbulent, statistically homogeneous flow with random transitions among multiple energy containing states. We decompose the velocity correlation functions on different sectors of the three-dimensional group… |

The complex differentiation process of the CD4+ T helper lymphocytes shapes the form and the range of the immune response to different antigenic challenges. Few mathematical and computational models have addressed this key phenomenon. We here present a multiscale approach in which two different… |

The Lagrangian description of turbulence is characterized by a unique con- ceptual simplicity and by an immediate connection with the physics of dis- persion and mixing. In this article, we report some motivations behind the Lagrangian description of turbulence and focus on the statistical… |

Networks are pervasive in computer science and in real world applications. It is often useful to leverage distinctive node features to regroup such data in clusters, by making use of a single representative node per cluster. Such contracted graphs can help identify features of the original networks… |

The (first-order) gravitational self-force correction to the spin-orbit precession of a spinning compact body along a slightly eccentric orbit around a Schwarzschild black hole is computed through the ninth postNewtonian order and to second order in the eccentricity, improving recent results by… |

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 according to the Mathisson-Papapetrou-Dixon model. The properties of the quadrupole tensor are clarified by identifying the… |

In this paper we propose a numerical method for the simulation of acousticfields, in presence of an obstacle in the physical domain, by finite difference solution of a two-dimensional differential model on boundary-fittedgrids. The computational process gathers the elliptic grid generation, the… |

During the last 20 years, three seismic sequences affected the Apenninic belt (central Italy):
Colfiorito (1997-98), L'Aquila (2009) and Amatrice Visso-Norcia Campotosto (2016-17).
They lasted for a long time, with a series of moderate-to-large earthquakes distributed over
40-60 km long Apenninic-… |
