In recent papers, new sets of Sheffer and Brenke polynomials based on higher order Bell numbers have been studied, and
several integer sequences related to them have been introduced. In the article other types of Sheffer polynomials are considered, by
introducing two sets of Euler-type polynomials. |

Agent-based modeling allows the description of very complex systems. To run large scale simulations of agent-based models in a reasonable time, it is crucial to carefully design data structures and algorithms. We describe the main computational features of agent-based models and report about the… |

We consider the problem of writing Glimm type interaction estimates for the
hyperbolic system
\begin{equation}\label{E:abs0}
u_t + A(u) u_x = 0.
\end{equation}
%only assuming that $A(u)$ is strictly hyperbolic.
The aim of these estimates is to prove that there is Glimm-type
functional $Q(u)$ such… |

The idea that individuals tend to choose a romantic partner following similarities on personality traits has always attracted much
attention in the psychological literature, although results were controversial. We conducted a new data analysis approach to
personality traits of 235 newlywed couples… |

Si discutono le definizione di soluzioni ad ODE discontinue in relazione al problema della ricostruzione delle traiettorie ottime da un feedback.
In particolare si danno condizioni su feedback stratificati alla Boltianskii-Brunovsky per avere l'uguaglianza fra soluzioni alla Krasowskii e… |

Active fluids comprise a variety of systems composed of elements immersed in a fluid environment which can convert some form of energy into directed motion; as such they are intrinsically out-of-equilibrium in the absence of any external force. A fundamental problem in the physics of active matter… |

In this paper, we systematically apply the mathematical structures by time-evolving measures developed in a previous work to the macroscopic modeling of pedestrian flows. We propose a discrete-time Eulerian model, in which the space occupancy by pedestrians is described via a sequence of Radon-… |

The paper addresses the calculation of the value at risk (VaR) of the mathematical provision applied in a fair valuation context. Following a balance-sheet approach, the classical definition of VaR needs some clarifications. For identifying worst cases it is opportune to observe that an increase in… |

Using an algorithm for simulating equilibrium configurations, we study a fluctuating helical polymer either (i) contained in a cylindrical pore or (ii) wound around a cylindrical rod. We work in the regime where both the contour length and the persistence length of the helical polymer are much… |
