let $t$ be a bounded operator on the banach space $x$ and $ph$ be an analytic self-map of the unit disk $bbb{d}$‎. ‎we investigate some operator theoretic properties of‎ ‎bilateral composition operator $c_{ph‎, ‎t}‎: ‎f ri t circ f circ ph$ on the vector-valued hardy space $h^p(x)$ for $1 leq p leq‎ ‎+infty$.‎ ‎compactness and weak compactness of $c_{ph‎, ‎t}$ on $h^p(x)$‎ ‎are characterized an...

We study syndetic sensitivity and mean for linear dynamical systems. For the aspect, we obtain some properties of adjoint operators left multiplication operators. also show that there exists a system (X×Y,T×S) such is cofinitely sensitive but (X,T) (Y,S) are not syndetically sensitive. if sensitive, where Y complex Banach space, spectrum T meets unit circle. results regarding perturbations.

We compute an asymptotic formula for the supremum of resolvent norm ||(ζ−T)−1|| over |ζ|≥1 and contractions T acting on n-dimensional Hilbert space, whose spectral radius does not exceed a given r∈(0,1). prove that this is achieved unit circle by analytic Toeplitz matrix.

Mouse spleen cells which are synthesizing IgE can sensitize rat skin for HACA. When such cells are treated with mouse interferon, their ability to sensitize rat skin is reduced or completely inhibited. Two hundred PRD50 units of interferon reduced HACA reactions by more than 50%; 600 units gave complete inhibition. Interferon may act by inhibiting IgE synthesis and/or release.

TomoTherapy Quality Assurance (TQA) is a software package developed to monitor certain aspects of machine performance. In this study, the TQA quantities or data trends most effective in monitoring energy drifts and magnetron stability were determined respectively. This retrospective study used data collected from three TomoHD units. The TQA modules investigated were Step-Wedge Helical, Step-Wed...

A number of recent methods developed for automatic classification of multiunit neural activity rely on a Gaussian model of the variability of individual waveforms and the statistical methods of Gaussian mixture decomposition. Recent evidence has shown that the Gaussian model does not accurately capture the multivariate statistics of the waveform samples' distribution. We present further data de...

Various parametric tests make assumptions of the normal distribution, including t-test, analysis of variance (ANOVA), correlation, and regression. Different from some researcher’s understanding, tests of normality are not for the normality of observed data but for normality of the population distribution of a random characteristic; e.g. assuming normality for the population distribution of the ...

This paper considers the estimation of the parameters of a copula via a simulated method of moments type approach. This approach is attractive when the likelihood of the copula model is not known in closed form, or when the researcher has a set of dependence measures or other functionals of the copula that are of particular interest. The proposed approach naturally also nests method of moments ...
