Relativistic astrometry has recently become an active field of research owing to new observational technologies which allow for accuracies of a microarcsecond. To assure this accuracy in data analysis, one has to perform ray tracing in a general relativistic framework including terms of the order… |

Sparse solvers are one of the building blocks of any technology for reliable and high-performance scientific and engineering computing. In this paper we present a software package which implements an efficient multigrid sparse solver running on Graphics Processing Units. The package is a branch of… |

We introduce a differential model to study damage accumulation processes in
presence of chemical reactions. The influence of micro-structure
leads to a nonlinear parabolic system characterized by the presence of a characteristic length. Here, we first present an analytical description of the… |

We consider discrete versions of the de la Vallée-Poussin algebraic operator. We give a simple sufficient condition in order that such discrete operators interpolate, and in particular we study the case of the Bernstein-Szego weights. Furthermore we obtain good error estimates in the cases of the… |

This study describes a semi-empirical model developed to estimate volumetric soil moisture (<mml:semantics>theta v</mml:semantics>) in bare soils during the dry season (March-May) using C-band (5.42 GHz) synthetic aperture radar (SAR) imagery acquired from the Sentinel-1 European… |

We study the phase separation of a binary mixture in uniform shear flow in the framework of the continuum convection-diffusion equation based on a Ginzburg-Landau free energy. This equation is solved both numerically and in the context of large-N approximation. Our results show the existence of… |

Long-range NMR data, namely residual dipolar
couplings (RDCs) from external alignment and paramagnetic
data, are becoming increasingly popular for the
characterization of conformational heterogeneity of multidomain
biomacromolecules and protein complexes. The
question addressed here is how much… |
