We discuss the orientation of e+e– + q~g events in terms of the polar and azimuthal angIes of the event plane w.r.t. the electron beam direction. We define an asymmetry of the azimuthal-angle distribution which, along with the left-right forward-backward polar-angle asymmetry, is sensitive to parity-violating effects in three-jet events; these have yet to be explored experimentally. We have eva...

This report specifies an information model of machine-tool-performance tests in the EXPRESS [1] language. The information model provides a mechanism for describing the properties and results of machine-tool-performance tests. The objective of the information model is a standardized, computer-interpretable representation that allows for efficient archiving and exchange of performance test data t...

We propose Vuong-type tests to select between two moment inequality models based on their Kullback–Leibler distances to the true data distribution. The candidate models can be either non-overlapping or overlapping. For each case, we develop a testing procedure that has correct asymptotic size in a uniform sense despite the potential lack of point identification. We show both procedures are cons...

The single index model is a generalization of the linear regression model with E yjx g x where g is an unknown function The model provides a exible alternative to the linear regression model while providing more structure than a fully nonparametric approach Although the tting of single index models does not require distributional assumptions on the error term the properties of the estimates dep...

In kaon physics, several new precision measurements on flavour variables and CP violation have performed in the recent years. Presented are a new precise determination of the CKM parameter |Vus|, which combines the results of all experiments together with recent theoretical progress, and new measurements of the ratio RK = Γ(K + → eν)/Γ(K → μν), which is sensitive to contributions of a possible ...

The current status of experimental tests of the electroweak sector of the Standard Model is reviewed.

Chemical carcinogenicity has been the target of numerous attempts to create predictive models alternative to the animal ones, ranging from short-term biological assays (e.g. mutagenicity tests) to theoretical models. Among the theoretical models, the application of the science of structure-activity relationships (SAR) has earned special prominence. The qualitative approach to SAR has lead to th...
