    Rotated twisted-mass: a convenient regularization scheme for isospin breaking QCD and QED lattice calculations

    We propose a scheme of lattice twisted-mass fermion regularization which is particularly convenient for application to isospin breaking (IB) QCD and QED calculations, based in particular on the so called RM123...

    Kaon mixing beyond the SM from Nf = 2 tmQCD and model independent constraints from the UTA

    We present the first unquenched, continuum limit, lattice QCD results for the matrix elements of the operators describing neutral kaon oscillations in extensions of the Standard Model. Owing to the accuracy of...

    Isospin breaking effects due to the up-down mass difference in lattice QCD

    We present a new method to evaluate with high precision leading isospin breaking effects due to the small mass difference between the up and down quarks using lattice QCD. Our proposal is applicable in princip...

    Twisted mass quarks and the phase structure of lattice QCD

    The phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable in correspondence of which the untwisted quark mass assumes positive...

    Combination of Carboplatin and Etoposide in The Management of Intraocular Retinoblastoma

    The combination of carboplatin and etoposide has been tested in intraocular retinoblastoma (IORB), in order to avoid enucleation or radiotherapy and to permit local therapy.

    Spectral maps from intraocular tumors by a new imaging technique using a modified echographic B-mode instrument

    A new imaging technique that combines spectral maps with the conventional B-mode display was applied to eyes affected by intraocular tumors in order to characterize tissutal structure. Here we describe a modul...
