Abstract We present a detailed photometric and spectroscopic analysis of DD CMa, based on published survey photometry new data. find an improved orbital period P o = 2.0084530(6) days. Our spectra reveal H β α absorptions with weak emission shoulders, we also color excess in the Wide-field Infrared Survey Explorer multiband photometry, interpreted as signatures circumstellar matter. model V -ba...

The primary reasons for conducting fundamental research are satisfying curiosity, acquiring knowledge, and achieving understanding. Here we develop why we believe it is essential to promote basic ecological research, despite increased impetus for ecologists to conduct and present their research in the light of potential applications. This includes the understanding of our environment, for intel...

The behaviour of the glottal Liljencrants-Fant (LF) parameters were studied across vowel, context, duration, stress and fundamental frequency. Using statistical analysis we attempted to account for the variation in the glottal parameters for a speaker and from the patterns observed create a model capable of predicting the parameters for a given utterance and fundamental frequency. The parameter...

Using the ARGUS detector at the e+e storage ring DORIS II, we have measured the Michel parameters , , and for ! l  decays in -pair events produced at center of mass energies in the region of the resonances. Using ! as spin analyzing tags, we nd e = 0:68 0:04 0:08, e = 1:12 0:20 0:09, e = 0:57 0:14 0:07, = 0:69 0:06 0:08, = 1:25 0:27 0:14 and = 0:72 0:18 0:10. In addition, we report the combine...

In the presence of nuisance parameters, we derive an explicit higher order asymptotic formula to compare the expected lengths of conndence intervals given by likelihood ratio statistics arising from the usual proole likelihood and various adjustments thereof. Highest posterior density regions, with approximate frequentist validity, are also included in the study.

For hypotheses of the type H0 : θ = θ0 vs H1 : θ 6= θ0 we demonstrate the equivalence of a Bayesian hypothesis test using a Bayes factor and the corresponding classical test, for a large class of models, which are detailed in the paper. In particular, we show that the role of the prior and critical region for the Bayes factor test is only to specify the type I error. This is their only role sin...
