The prevalence and incidence of Trypanosoma evansi infections in village buffaloes in Central Java were estimated using parasitological tests, two antigen-detection ELISAs (2G6 Ag-ELISA and Tr7 Ag-ELISA), an antibody-detection ELISA (IgG ELISA) and a card agglutination test (CATT). Of 2387 village buffaloes tested in five districts, 4 % (95 % confidence interval [CI]: 3 %, 5 %) were positive wi...

The name Ernest Henley to me is inexorably linked with the idea of symmetry tests. Indeed I learned my first information about parity violation in nuclei from his classic work on time reversal and parity[1] and it was reading this paper which eventually led to my interest in and work in this field. Of course, it is not just Prof. Henley who has long been interested in the subject of invariance....

This paper provides an extension of Vuong’s (1989, Econometrica, 57, pp.307–333) model selection test to the multivariate case. We use the Kullback–Leibler Information Criterion (KLIC) to measure the closeness of a model to the truth to provide a diagnosis of many competing models where the models are not correctly specified. After investigating the asymptotic joint distribution of the likeliho...

The Standard-Model Extension (SME) provides a comprehensive effective field-theory framework for the study of CPT and Lorentz symmetry. This work reviews the structure and philosophy of the SME and provides some intuitive examples of symmetry violation. The results of recent gravitational tests performed within the SME are summarized including analysis of results from the Laser Interferometer G...
