    The research covers the results of experimental studies of the effect character of nanocomposite coatings with different physical and chemical parameters (type, roughness, hydrophilic-hydrophobic characteristics) on structural and functional properties (adhesive potential, phenotype, gene expression) of mesenchymal stem cells (MSCs). On the tested nanocoatings (Al2O3, ZrO2, Ta2O5) the capability of oxide coating Al2O3 to enrich the in vitro cultured bone marrow (BM) with the cells of MSCs phenotype markers as well as to increase the expression rate of ido gene in them, which may extend the spectrum of their therapeutic application in clinics, has been found.

    Partial Schauder estimates for second-order elliptic and parabolic equations

    Full text link
    We establish Schauder estimates for both divergence and non-divergence form second-order elliptic and parabolic equations involving H\"older semi-norms not with respect to all, but only with respect to some of the independent variables.Comment: CVPDE, accepted (2010)

    Analytic solutions and Singularity formation for the Peakon b--Family equations

    Full text link
    Using the Abstract Cauchy-Kowalewski Theorem we prove that the bb-family equation admits, locally in time, a unique analytic solution. Moreover, if the initial data is real analytic and it belongs to HsH^s with s>3/2s > 3/2, and the momentum density u0u0,xxu_0 - u_{0,{xx}} does not change sign, we prove that the solution stays analytic globally in time, for b1b\geq 1. Using pseudospectral numerical methods, we study, also, the singularity formation for the bb-family equations with the singularity tracking method. This method allows us to follow the process of the singularity formation in the complex plane as the singularity approaches the real axis, estimating the rate of decay of the Fourier spectrum

    Search for the associated production of the Higgs boson with a top-quark pair

    Get PDF
    A search for the standard model Higgs boson produced in association with a top-quark pair t t ¯ H (tt¯H) is presented, using data samples corresponding to integrated luminosities of up to 5.1 fb −1 and 19.7 fb −1 collected in pp collisions at center-of-mass energies of 7 TeV and 8 TeV respectively. The search is based on the following signatures of the Higgs boson decay: H → hadrons, H → photons, and H → leptons. The results are characterized by an observed t t ¯ H tt¯H signal strength relative to the standard model cross section, μ = σ/σ SM ,under the assumption that the Higgs boson decays as expected in the standard model. The best fit value is μ = 2.8 ± 1.0 for a Higgs boson mass of 125.6 GeV
