The hidden side of COVID-19 spread in Italy
Luigi Brugnano, Felice Iavernaro, Paolo Zanzottera
Background. The paper concerns the SARS-CoV2 (COVID-19) pandemic that, starting from the end of February 2020, began spreading along the Italian peninsula, by first attacking small…
A multi-region variant of the SIR model and its extensions
Luigi Brugnano, Felice Iavernaro
In this note, we describe simple generalizations of the basic SIR model for epidemic, in case of a multi-region scenario, to be used for predicting the COVID-19 epidemic spread in…
On the use of the Infinity Computer architecture to set up a dynamic precision floating-point arithmetic
Pierluigi Amodio, Luigi Brugnano, Felice Iavernaro +1
We devise a variable precision floating-point arithmetic by exploiting the framework provided by the Infinity Computer. This is a computational platform implementing the Infinity A…
Arbitrarily high-order energy-preserving methods for simulating the gyrocenter dynamics of charged particles
Luigi Brugnano, Felice Iavernaro, Ruili Zhang
Gyrocenter dynamics of charged particles plays a fundamental role in plasma physics. In particular, accuracy and conservation of energy are important features for correctly perform…
