The existence of primordial adiabatic Gaussian random-phase density uctuations is a generic prediction of innation. The properties of these uctuations are completely speciied by their power spectrum A 2 S (k). The basic cosmological parameters and the primordial power spectrum together completely specify predictions for the cosmic microwave background radiation anisotropy and large scale struct...

In this research, structural and electronic properties of ZnCdn-1Ten clusters (n=1-10) have been studied by formalism of density functional theory and using the projector augmented wave within local density approximation. The structural properties (such as bond length/angle and coordination number), electronic and optical properties (such as binding energy, Kohn-Sham spect...

Relativistic shock models of gamma-ray bursts may be tested by comparison of their predicted low energy asymptotic spectral indices s to observations. Synchrotron radiation theory predicts that the instantaneous spectrum has s = −1/3 and the spectrum integrated over the radiative decay of the electrons’ energies has s = 1/2, with other cases lying between these limits. We examine the spectra of...

objectives: this study compared the effects of individual and group training on general health and stress of parents of children with autism spectrum disorders. methods: a sample of 75 parents of children referring to autistic children foundation (including 50 parents in two experimental groups and 25 parents in control group) was taken into account. sample parents were selected through accessi...

the degree kirchhoff index of a connected graph $g$ is defined as‎ ‎the sum of the terms $d_i,d_j,r_{ij}$ over all pairs of vertices‎, ‎where $d_i$ is the‎ ‎degree of the $i$-th vertex‎, ‎and $r_{ij}$ the resistance distance between the $i$-th and‎ ‎$j$-th vertex of $g$‎. ‎bounds for the degree kirchhoff index of the line and para-line‎ ‎graphs are determined‎. ‎the special case of regular grap...

The Selberg trace formula on a Riemann surface X connects the discrete spectrum of the Laplacian with the length spectrum of the surface, that is, the set of lengths of the closed geodesics of on X. The connection is most strikingly expressed in terms of the Selberg zeta function, which is a meromorphic function of a complex variable s that is defined for <(s) > 1 in terms of the length spectru...

BACKGROUND AND AIMS Probiotics, including Saccharomyces boulardii, have been advocated for the prevention of Clostridium difficile infection. The aim of this project was to evaluate the effects of the removal of S. boulardii from an automatic antibiotic order set and hospital formulary on hospital onset C. difficile infection rates. DESIGN A retrospective chart review was performed on all pat...

The increasing emergence of multi-drug resistant streptococci poses a serious threat to public health worldwide. Bacteriophage lysins are promising alternatives to antibiotics; however, their narrow lytic spectrum restricted to closely related species is a central shortcoming to their translational development. Here, we describe an efficient method for rapid screening of engineered chimeric lys...

Discrete Fourier transformations (DFTs) provide a useful tool to assign a phylogenetic tree (PGT) to an observed frequency of nucleotide patterns in DNA sequences of species. The advantage of this sort of spectral analysis is that it allows global correction for multi-substitution processes [1]. SPECTRAL ANALYSIS OF PGTS Two spectras characterize a PGT, the probability spectrum p(T), and the ex...
