Metabolomics, the systematic analysis of potential metabolites in a biological specimen, has been increasingly applied to discovering biomarkers, identifying perturbed pathways, measuring therapeutic targets, and discovering new drugs. By analyzing and verifying the significant difference in metabolic profiles and changes of metabolite biomarkers,(More)
Based on the “convexly separable” concept, we present a solid geometric theory and a new general framework to design piecewise linear classifiers for two arbitrarily complicated nonintersecting classes by using a “multiconlitron,” which is a union of multiple conlitrons that comprise a set of hyperplanes or linear functions(More)
According to the basic theory of wavelet, this paper used matlab software simulation to study image compression problem. Compared with traditional methods, it is more simple and effective.Wavelet image compression technology solves the contradiction of time and frequency domains localization which can not be achieved by the Fourier transform. For improving(More)
This paper describes a method for traffic signs detection, tracking and recognition. Color and shape are combined to detect signs. Hue and saturation are used to detect the red color of the sign. Circles are detected through the improved round-degree method of extracting area feature parameters. An improved Kalman filter is introduced to track multiple(More)
Conventional scrambling method based on high dimensional matrix transformation has the following deficiencies: (1) there is no generalized high dimensional scrambling matrix generation algorithm, so the prevalent scrambling methods are to use special matrices such as high dimensional Arnold transformation matrix, Fibonacci-Q transformation matrix, A-type(More)
In the existing applications of streaming media, the formats of streaming media contents are multiple. How to effectively protect various-format streaming media contents is a new challenge. A new protection scheme based on online encryption for streaming media is proposed in this paper. It achieves content protection for various-format streaming media by(More)
To handle the uncertain multiple attribute decision problem that the decision index value is hard to define accurately, this paper studies on the hybrid multi-attribute decision model of grey target when the index values are real number, interval number and triangular fuzzy number which exist together. According to the basic connotations of grey target(More)
Mutations in the plasminogen activator inhibitor-1 (PAI-1) gene, along with increased PAI-1 levels, have been implicated in the pathogenesis of polycystic ovarian syndrome (PCOS). We investigated a possible influence of the promoter polymorphism (-844 A/G and -675 4G/5G) in the PAI-1 gene on plasma PAI-1 levels in 126 PCOS patients and 97 healthy controls.(More)
This paper aims to review the development of scientific concepts of microecology and ecology of microbes and the role and functions of beneficial microorganisms in aquaculture and mariculture. Beneficial microorganisms play a great role in natural and man-made aquatic ecosystems based on the co-evolution theory in living biosphere on earth. Their functions(More)
Stevioside, a diterpene glycoside isolated from Stevia rebaudiana, has been reported to have anti-inflammatory properties. However, the underlying molecular mechanisms are not well understood. The objective of this study was to investigate the molecular mechanism of stevioside in modifying lipopolysaccharide (LPS)-induced signal pathways in RAW264.7 cells.(More)
