This study was designed to assess the changes in nonlinear properties of heart rate (HR) variability (HRV) during the menstrual cycle by means of complexity measures, including sample entropy (SampEn) and correlation dimension (CD), and explore probable physiological interpretations for them. In 16 healthy women (mean age: 23.8 +/- 2.7 yr), complexity(More)
The incidence of contrast-induced nephropathy has an increasing trend as a result of increased use of contrast media during coronary interventional procedures. Contrast-induced nephropathy is one of the major causes for hospital acquired renal failure after coronary interventional procedures. In this study, a total of 126 enrolled patients undergoing(More)
Metaphor processing has been a heated topic in NLP. Cognitive properties of a word are important in metaphor understanding and generation. But data collected automatically tend to be reduced in both quantity and quality. This paper introduces CogBank a database of Chinese concepts and their associated cognitive properties. The database was constructed using(More)
In this paper, we present a Chinese lexical taxonomy, a hierarchically organization of Chinese lexical classes of nouns, verbs and adjectives. We first describe the structure of this taxonomy and then present the methods we used to build it. The distinctive characteristics of this lexical taxonomy are: 1) we use definition frame to describe each lexical(More)
Heart Rate Variability (HRV) indicates the variation of heart rate about its mean value. HRV has been found to be influenced by various physiological phenomena and also by various pathologies. In this paper the influence of Thyroid on HRV data has been investigated. For the purpose of investigation the Spectral Entropy (SpEn) values of six Thyroid and ten(More)
Either word sense classification or word sense clustering can not avoid this problem: what features people can get from word meaning that can be used as the tools employed for producing word sense ontology. In this paper, we present a lexical semantic-syntactic model to define and subcategorize a noun class—attribute noun class, by acquiring syntactic(More)
Cisapride has been shown to have electrophysiological effects on the heart. The aim of this study was to investigate whether cisapride has effects on cardiac hypertrophy. Rat and cellular models of cardiac hypertrophy were used in this study. Cell surface area (CSA), mRNA and protein expression were used to evaluate cardiac hypertrophy. Cardiac function was(More)
In this paper, we compare the use of argument structure in Chinese verb sense taxonomy (CVT), which is a hierarchy structure constituted by verb lexical classes, and Chinese Propbank (CPB). The major difference of the usage of argument structure between these two independent resources is: CVT uses argument structure to cluster verb senses, while CPB uses it(More)
