The Canadian Folk Music Journal/The Canadian Journal for Traditional Music - La Revue de musique folklorique canadienne: Reflections on Thirty Years of Writing about Folk and Traditional Music in Canada

This paper examines the genesis of the CJTM/RMFC over its thirty year existence. These “partial” reflections include discussion of issues surrounding folk music collection and classification, as well as ongoing debates surrounding what constituted real folk music. The over 200 articles and reviews in the Journal’s 30 volumes show emergent ideas in ethnomusicology and folklore related to fieldwork, changing paradigms with respect to writing about music, and the relation of musical performance to musical research Tensions and competing paradigms between French-speaking and English-speaking approaches are also considered. Finally, questions about the place of the Journal in the context of current ethnomusicological research, as well as comparisons with other related journals, including Ethnologies, Ethnomusicology,and the Journal of American Folklore are raised

The classical capacity of quantum thermal noise channels to within 1.45 bits

We find a tight upper bound for the classical capacity of quantum thermal noise channels that is within $1/\ln 2$ bits of Holevo's lower bound. This lower bound is achievable using unentangled, classical signal states, namely displaced coherent states. Thus, we find that while quantum tricks might offer benefits, when it comes to classical communication they can only help a bit.Comment: Two pages plus a bi

An X-ray measurement of Titan's atmospheric extent from its transit of the Crab Nebula

Saturn's largest satellite, Titan, transited the Crab Nebula on 5 January 2003. We observed this astronomical event with the {\it Chandra} X-ray Observatory. An ``occultation shadow'' has clearly been detected and is found to be larger than the diameter of Titan's solid surface. The difference gives a thickness for Titan's atmosphere of 880 $\pm$ 60 km. This is the first measurement of Titan's atmospheric extent at X-ray wavelengths. The value measured is consistent with or slightly larger than those estimated from earlier Voyager observations at other wavelengths. We discuss the possibility of temporal variations in the thickness of Titan's atmosphere.Comment: 14 pages, 5 figures, AASTeX preprint. Accepted for publication in the Astrophysical Journa

Statistics of soliton-bearing systems with additive noise

We present a consistent method to calculate the probability distribution of soliton parameters in systems with additive noise. Even though a weak noise is considered, we are interested in probabilities of large fluctuations (generally non-Gaussian) which are beyond perturbation theory. Our method is a further development of the instanton formalism (method of optimal fluctuation) based on a saddle-point approximation in the path integral. We first solve a fundamental problem of soliton statistics governing by noisy Nonlinear Schr\"odinger Equation (NSE). We then apply our method to optical soliton transmission systems using signal control elements (filters, amplitude and phase modulators).Comment: 4 pages. Submitted to PR
