For a family F (a collection of subsets of Z+), the notion of Findependence is defined both for topological dynamics (t.d.s.) and measurable dynamics (m.d.s.). It is shown that there is no non-trivial {syndetic}-independent m.d.s.; a m.d.s. is {positive-density}-independent if and only if it has completely positive entropy; and a m.d.s. is weakly mixing if and only if it is {IP}independent. For...
We prove that C-robustly transitive diffeomorphisms on surfaces with boundary do not exist, and we exhibit a class of diffeomorphisms of surfaces with boundary which are C−robustly transitive, with k ≥ 2. This class of diffeomorphisms are examples where a version of Palis’ conjecture on surfaces with boundary, about homoclinic tangencies and uniform hyperbolicity, does not hold in the C−topolog...
The renormalization, at the next-to-leading order in α s , of the ∆B = 2 operators at the lowest order in the heavy quark expansion, namely in the static theory, is computed taking into account previously missed contributions. These operators are relevant for the calculation of the B 0 – ¯ B 0 mixing on the lattice.
The NOMAD experiment collected unprecedent neutrino data samples, matching both the large statistics of massive calorimeters and the reconstruction quality of bubble chambers. This paper describes the determination of the weak mixing angle which is ongoing in NOMAD, with a target precision of ∼ 1%. In addition, measurements of the νµ quasi-elastic cross-section and of neutrino Charged Current d...
Status of the problem of neutrino masses, mixing and oscillations is discussed. Future perspectives are briefly considered.
In this study a new simple selective and sensitive spectrophotometric procedure for determination of Fe(III) is described. It is based on the formation of a colored complex between ferric iron and ethyl maltol, a strong and highly selective ligand for Fe(III). After mixing sample and reagent, and incubating at the room temperature, Fe(III)-ethyl maltol complex was extracted with different ...
The invisible inks have many applications, including the use of banknote printing, code load, securitydocuments and much of its application in the exchange of security information. Photoluminescenceproperties of lanthanide compounds that attracted the attention of many scholars in recent decades are one ofthe important factors in drying and fluidity of the ink. The solvent eva...
A brief summary of the status of neutrino masses, mixing and oscillations is presented. Neutrinoless double β-decay is considered. Predictions for the effective Majorana mass are reviewed. A possible test of the calculations of nuclear matrix elements of the 0νββ-decay is proposed.
