This unit covers statistical methods of linkage analysis that do not require the assumption of a detailed genetic model, as is required for standard lod score analysis. The unit has been updated to include the latest methods in sib-pair analysis, including updates to using the software program SIBPAL as well as the relative-pair analysis software applications GENEHUNTER, GENEHUNTER PLUS, and Me...
We review how experimental data collected at the HERA lepton-hadron collider have improved our theoretical and phenomenological understanding of the standard model, and specifically of its QCD sector. Invited talk given at the EPS Conference on High Energy Physics Tampere, Finland, July 1999 to be published in the proceedings
Pairs of items describing objectionable behaviors were rated for their overall morality. Contrary to additive or constant-weight averaging models, the ratings were demonstrated to depend upon the range as well as the average scale value of the component behaviors. A range model accounted for more than half of the variance left unexplained by the additive models. One interpretation of the range ...
Recently I suggested that for the deconfining phase transition in a pure gauge theory, the behavior of the usual order parameter — the Polyakov loop — may be correlated with the pressure. In fact this correspondence is implicit in studies of two colors done by Engels, Fingberg, Redlich, Satz, and Weber in 1989 [1]. For two colors, the deconfining transition appears to be of second order [1–3]. ...
Gravitation governs the expansion and fate of the universe, and the growth of large-scale structure within it, but has not been tested in detail on these cosmic scales. The observed acceleration of the expansion may provide signs of gravitational laws beyond general relativity (GR). Since the form of any such extension is not clear, from either theory or data, we adopt a model-independent appro...
I give an introduction and overview of recent developments in high precision tests of the Standard Model. This includes a summary of Z-pole measurements, a brief account of the NuTeV result on neutrino-nucleon scattering, the anomalous magnetic moment of the muon, and implications for the Higgs boson mass.
The aim of this paper is to review likelihood ratio test procedures in multivariate linear models, focusing on projection matrices. It is noted that the projection matrices to the spaces spanned by mean vectors in hypothesis and alternatives play an important role. Some basic properties are given for projection matrices. The models treated include multivariate regression model, discriminant ana...
Large-eddy simulation (LES) has become an effective research tool for the atmospheric bound¬ary layer (ABL) and probably the most in the atmospheric surface layer LES suffers from inherent underresolution and poor subgrid-scale (SGS) model performance. To develop improved SGS models a methodology for testing model perfor¬mance is needed. Previous tests rely on comparing the modeled and measured...
