Preface Our capabilities of both generating and collecting data have been increasing rapidly in the last several decades. Contributing factors include the widespread use of bar codes for most commercial products, the computerization of many business, scientiic and government transactions and managements, and advances in data collection tools ranging from(More)
Stream data mining research has been active in recent years. Popular surveys on stream data systems and stream data processing include Babu and Widom [ There have been extensive studies on stream data management and the processing of continuous queries in stream data. For a description of synopsis data structures for stream data, see Gibbons and Matias(More)
In this paper, we employ a novel approach to metarule-guided, multi-dimensional association rule mining which explores a data cube structure. We propose algorithms for metarule-guided mining: given a metarule containing p predicates, we compare mining on an n-dimensional (n-D) cube structure (where p < n) with mining on smaller multiple pdimensional cubes.(More)
PURPOSE Our purpose was to study effects of creatine (Cr) supplementation on muscle metabolites noninvasively by means of magnetic resonance spectroscopy (MRS) before and after supplementation with Cr or placebo. METHODS 1H-MRS was used in a comprehensive, double-blind, cross-over study in 10 volunteers to measure Cr in m. tibialis anterior and m. rectus(More)
A data mining system, DBMiner, has been developed for interactive mining of multiple-level knowledge in large relational databases and data warehouses. The system implements a wide spectrum of data mining functions, including characterization, comparison, association, clas-siication, prediction, and clustering. By incorporating several interesting data(More)
Doping in sport is often very present in the media. Doping does not only concern top level sports but it also has an impact on sport as a whole. Young athletes may be influenced by its role models. In Switzerland there are no exact data on this influence or on the use of doping by adolescents. In this article, the effects and side-effects especially on(More)
Human investigators instinctively segment medical images into their anatomical components, drawing upon prior knowledge of anatomy to overcome image artifacts, noise, and lack of tissue contrast. The authors describe: 1) the development and use of a brain tissue probability model for the segmentation of multiple sclerosis (MS) lesions in magnetic resonance(More)
PURPOSE Our purpose was to study the effects and side effects of creatine (Cr) supplementation on high-intensity, short-term muscle work, on biochemical parameters related to Cr metabolism in blood and urine, and on muscle volume of the lower limb muscles. METHODS A cycling ergometer was used in a double-blind, cross-over study on 10 well-trained male(More)
We report the findings of the analysis of 75 different nutritional supplements bought through the internet. Seven products (all from the class of prohormones) contained other hormone substances than indicated on the labels, and two further products contained ephedrine and caffeine without a clear indication on the labels.
