Relativistic Quarkonia from Anisotropic Lattices

We report on new results for the spectrum of quarkonia using a fully relativistic approach on anisotropic lattices with quark masses in the range from strange to bottom. A fine temporal discretisation also enables us to resolve excitations high above the ground state. In particular we studied the mass dependence and scaling of hybrid states.Comment: 4 pages, 5 figures. Lattice 2000 (Heavy Quark Physics

A visual approach to measuring personality systems

A visual approach to measuring implicit personality systems is explored in this article. Six scales, consisting of optical stimuli (icons), were developed by conducting factor analyses using data from 3 studies with more than 70.000 participants. Internal consistencies and testretest-correlations of the six scales were satisfactory. Incremental validity of the visual scales was examined in 3 studies (N = 232). Results from regression analyses showed that the visual scales are distinct from self-report scales and can explain additional variances in behaviorally anchored rating scales and supervisor ratings. The gain in explained variance beyond selfreport measures was on average 140% in the three studies. The authors conclude that measuring personality dimensions via a visual method can make a significant contribution in explaining implicit information processing and behavior and deserves consideration in applied settings. For example, using visuals that are consistent with implicit versus explicit personality systems of the key audience may deepen our understanding of advertising effectiveness, media use and consumer behavior. --implicit,personality systems interaction,PSI-theory,visual questionnaire (ViQ),Jungian typology

A biophysical approach to large-scale protein-DNA binding data

About this book * Cutting-edge genome analysis methods from leading bioinformaticians An accurate description of current scientific developments in the field of bioinformatics and computational implementation is presented by research of the BioSapiens Network of Excellence. Bioinformatics is essential for annotating the structure and function of genes, proteins and the analysis of complete genomes and to molecular biology and biochemistry. Included is an overview of bioinformatics, the full spectrum of genome annotation approaches including; genome analysis and gene prediction, gene regulation analysis and expression, genome variation and QTL analysis, large scale protein annotation of function and structure, annotation and prediction of protein interactions, and the organization and annotation of molecular networks and biochemical pathways. Also covered is a technical framework to organize and represent genome data using the DAS technology and work in the annotation of two large genomic sets: HIV/HCV viral genomes and splicing alternatives potentially encoded in 1% of the human genome

Perfect Gauge Actions on Anisotropic Lattices

On anisotropic lattices, where generally the lattice is rather coarse in spatial directions, a parametrized classically perfect action could help reducing lattice artifacts considerably. We investigate the possibility of constructing such actions for SU(3) gauge theory. We present two different methods to do so, either repeating the procedure used to create our newly parametrized isotropic FP action, or performing one single step starting with the isotropic result. The anisotropic action is parametrized using an ansatz including anisotropically APE-like smeared (``fat'') links. The parametrized classically perfect action with anisotropy $\xi=a_s/a_t=2$ is constructed and the renormalized anisotropy is measured using the torelon dispersion relation. It turns out that the renormalization is small.Comment: Lattice 2000 (Improvement and Renormalisation), 4 pages, 9 eps-figures, Late

Upgraded viscous flow analysis of multi-element airfoils

A description of an improved version of the NASA/Lockheed multi-element airfoil analysis computer program is presented. The improvements include several major modifications of the aerodynamic model as well as substantial changes of the computer code. The modifications of the aerodynamic model comprise the representation of the boundary layer and wake displacement effects with an equivalent source distribution, the prediction of wake parameters with Green's lag-entrainment method, the calculation of turbulent boundary layer separation with the method of Nash and Hicks, the estimation of the onset of confluent boundary layer separation with a modified form of Goradia's method, and the prediction of profile drag with the formula of Squire and Young. The modifications of the computer program for which the structured approach to computer software development was employed are also described. Important aspects of the structured program development such as the functional decomposition of the aerodynamic theory and its numerical implementation, the analysis of the data flow within the code, and the application of a pseudo code are discussed

An Improved Version of the NASA-Lockheed Multielement Airfoil Analysis Computer Program

An improved version of the NASA-Lockheed computer program for the analysis of multielement airfoils is described. The predictions of the program are evaluated by comparison with recent experimental high lift data including lift, pitching moment, profile drag, and detailed distributions of surface pressures and boundary layer parameters. The results of the evaluation show that the contract objectives of improving program reliability and accuracy have been met
