    M. Degli Esposti, S. Isola, Transfer operators for infinite dimensional dynamical systems

    No full text
    We outline some recent approaches relying on cluster expansion techniques to study transfer operators associated to coupled maps lattices. These are infinite dimensional dynamical systems involving interactions between continuous state elements which evolve in discrete time and are distributed on a lattice. Existence of SRB measures for such systems is referred to as space-time chaos

    A characterisation of Wigner-Yanase skew information among statistically monotone metrics

    No full text
    Let M-n = M-n(C) be the space of n x n complex matrices endowed with the Hilbert-Schmidt scalar product, let S-n be the unit sphere of M-n and let D-n subset of M-n be the space of strictly positive density matrices. We show that the scalar product over D-n introduced by Gibilisco and Isola(3) (that is the scalar product induced by the map D-n There Exists rho --> rootrho is an element of S-n) coincides with the Wigner-Yanase monotone metric

    Il saggio analizza le opere d'arte, tanto in scultura come in pittura, realizzate nel XVII e nel XVIII secolo a ornamento della chiesa e del monastero camaldolese di San Michele in Isola a Murano. Esso si completa di una cronologia di tutti gli interventi pittorici, molti dei quali non più esistenti, attuati nell'arco cronologico considerat

    Internal fixation for the treatment of multiple physeal tibial fractures in a dog

    This case report describes a pinning fixation for the treatment of three tibial physeal fractures in a 3 months old mixed-breed dog. The radiographic study revealed the presence of a severely proximal dislocation of the tibial diaphysis along with multiple fractures of the proximal and distal tibial physes, distal femoral physis and fibula as well. An open reduction and internal fixation technique (ORIF) were performed using crossed K-wires for proximal and distal tibialphyseal fixation and a tension band to address the tibial tuberosity avulsion fracture. Postoperative radiographs showed proper fracture reduction, tibia alignment and correct implant positioning. Clinical and radiographic rechecks highlighted a progressive limb weight-bearing gradual resolution of distal limb edema andf racture healing. The described open surgical treatment allowed for a satisfactory clinical outcome as the preservation of limb joint function and tibial anatomy determined an early return to function at 45 days of follow-up
