Quadrature convergence of the extended Lagrange interpolant L 2n+1 f for any continuous function f is studied, where the interpolation nodes are the n zeros τ i of an orthogonal polynomial of degree n and the n + 1 zerosˆτ j of the corresponding " induced " orthogonal polynomial of degree n + 1. It is found that, unlike convergence in the mean, quadrature(More)
BACKGROUND Decoy receptor 3 (DcR3) has been reported to be involved in different cancers. However, few related researches have been accomplished on the role of DcR3 in lung cancer. OBJECTIVE To explore the expression level and clinicopathological implication of DcR3 protein in lung cancer tissues. MATERIALS AND METHODS Immunohistochemistry was used to(More)
MicroRNA (miRNA) played an important role in the progression of liver cancer and its diagnostic and prognostic values have been frequently studied. However, different microarray techniques and small sample size led to inconsistent findings in previous studies. We performed a comprehensive meta-analysis of a total of 357 tumor and 283 noncancerous samples(More)
Given an integer n ~ 1, and the orthogonal polynomial1r n (· ; du) of degree n relative to some positive measure du, the polynomial system "induced" by 1r n is the system of orthogonal polynomials {7rk,n} corresponding to the modified measure dUn = 1r~du. Our interest here is in the problem of determining the coefficients in the three-term recurrence(More)
