The paper deals with a special filtered approximation method, which originates interpolation polynomials at Chebyshev zeros by using de la Vallée Poussin filters. In order to get an optimal approximation in spaces of locally continuous functions equipped with weighted uniform norms, the related… |

This paper provides a numerical approach for solving optimal control
problems governed by ordinary differential equations. Continuous
extension of an explicit, fixed step-size Runge-Kutta scheme is used in
order to approximate state variables; moreover, the objective function
is… |

We investigate front propagation in systems with diffusive and subdiffusive behavior. The scaling behavior of moments of the diffusive problem, both in the standard and in the anomalous cases, is not enough to determine the features of the reactive front. In fact, the shape of the bulk of the… |

We consider the Cauchy problem for $n\times n$ strictly hyperbolic
systems of
nonresonant balance laws
$$
\left\{\begin{array}{c}
u_t+f(u)_x=g(x,u), \qquad x \in \reali, t>0\\
u(0,.)=u_o \in \L1 \cap \BV(\reali; \reali^n), \\
| \la_i(u)| \geq c > 0 \mbox{ for all } i\in \{1,\ldots,n\}, \\

Online social networks are nowadays one of the most effective and widespread tools used to share information. In addition to being employed by individuals for communicating with friends and acquaintances, and by brands for marketing and customer service purposes, they constitute a primary source of… |

We present the first analytic computation of the Detweiler-Barack-Sago gauge-invariant redshift function for a small mass in eccentric equatorial orbit around a spinning black hole. Our results give the redshift contributions that mix eccentricity and spin effects, through second order in… |

Soil N2O emissions were monitored throughout a 3-year crop rotation including maize, fennel and a ryegrass-clover. sward, at Borgo Cioffi NitroEurope site. N2O emission rates were highly variable in time and space and controlled by soil nitrogen and soil water content. The N2O effluxes were low for… |

Primary biliary cholangitis (PBC) is a chronic, cholestatic, immune-mediated, and progressive liver disorder. Treatment to preventing the disease from advancing into later and irreversible stages is still an unmet clinical need. Accordingly, we set up a drug repurposing framework to find potential… |

We report results from a high-resolution numerical study of fluid particles transported by a fully developed turbulent flow at R? = 280. Single-particle trajectories were followed for a time range spanning more than three decades, from less than a tenth of the Kolmogorov timescale up to one large-… |
