Self-interacting polynomials
F. Vivaldi
We introduce a class of dynamical systems of algebraic origin, consisting of self-interacting irreducible polynomials over a field. A polynomial f is made to act on a polynomial g…
Scaling dynamics of a cubic interval exchange transformation
J. H. Lowenstein, F. Vivaldi
We study the dynamics of renormalisation of an interval exchange transformation which features exact scaling (the cubic Arnoux-Yoccoz model). Using a symbolic space that describes…
Geometric representation of interval exchange maps over algebraic number fields
G. Poggiaspalla, J. H. Lowenstein, F. Vivaldi
We consider the restriction of interval exchange transformations to algebraic number fields, which leads to maps on lattices. We characterize renormalizability arithmetically, and…
The ASTRI Cherenkov Camera: from the prototype to the industrial version for the Mini-Array
G. Sottile, P. Sangiorgi, C. Gargano +37
The observation of energetic astronomical sources emitting very high-energy gamma-rays in the TeV spectral range (as e.g. supernova remnants or blazars) is mainly based on detectin…
Mechanical Ventilator Milano (MVM): A Novel Mechanical Ventilator Designed for Mass Scale Production in Response to the COVID-19 Pandemic
C. Galbiati, A. Abba, P. Agnes +145
Presented here is the design of the Mechanical Ventilator Milano (MVM), a novel mechanical ventilator designed for rapid mass production in response to the COVID-19 pandemic to add…
One-dimensional dynamics for travelling fronts in coupled map lattices
R. Carretero-González, D. K. Arrowsmith, F. Vivaldi
Multistable coupled map lattices typically support travelling fronts, separating two adjacent stable phases. We show how the existence of an invariant function describing the front…
Mode-locking in coupled map lattices
R. Carretero-González, D. K. Arrowsmith, F. Vivaldi
We study propagation of pulses along one-way coupled map lattices, which originate from the transition between two superstable states of the local map. The velocity of the pulses e…
