PURPOSE We propose a patient-specific algorithm for seizure prediction using multiple features of spectral power from electroencephalogram (EEG) and support vector machine (SVM) classification. METHODS The proposed patient-specific algorithm consists of preprocessing, feature extraction, SVM classification, and postprocessing. Preprocessing removes(More)
I n channel structures characterized by a powerful retailer (e.g., Wal-Mart, Home Depot), the dominant retailer's acceptance of a manufacturer's new product often determines the success of the new offering. Focusing on a manufacturer in such a market, we develop an approach to positioning and pricing a new product that directly incorporates the retailer's(More)
Visual exploration has proven to be a powerful tool for multivariate data mining and knowledge discovery. Most visualization algorithms aim to find a projection from the data space down to a visually perceivable rendering space. To reveal all of the interesting aspects of multimodal data sets living in a high-dimensional space, a hierarchical visualization(More)
land. The authors thank the two anonymous JMR reviewers for their helpful comments and guidance. Consumers often use both objective and subjective criteria to evaluate a product. For example, power tool users may evaluate a power tool on the basis of not only its objective attributes, such as price and switch type, but also its subjective characteristics,(More)
Consumers' time allocation decisions among various activities are fundamental to marketing research and consumer behavior. The authors construct a dynamic panel data model to examine how consumers allocate time to a portfolio of leisure activities over time. The data comprise a longitudinal panel in which the authors tracked 287 U.S. consumers' time use,(More)
In order to search for sulfated polysaccharides in different invertebrate connective tissues and to examine their biological activities, we have isolated three types of polysaccharides from the body wall of the three sea cucumbers Holothuria edulis, Apostichopus japonicas and Holothuria nobilis. The physicochemical properties and anticoagulant activities of(More)
PURPOSE This paper examines the effect of spatial aggregation error on statistical estimates of the association between spatial access to health care and late-stage cancer. METHODS Monte Carlo simulation was used to disaggregate cancer cases for two Illinois counties from zip code to census block in proportion to the age-race composition of the block(More)
BACKGROUND It was well known that the clinical use of chemotherapeutic drugs is restricted by severe adverse reactions and drug resistances. Thus it is necessary to figure out a strategy to increase the specific anti-tumor efficiency of chemotherapeutic drugs. Apigenin, a kind of flavonoids, has been reported to possess anticancer activities with very low(More)
