—The code comparison technology plays an important role in the fields of software security protection and plagiarism detection. Nowadays, there are mainly FIVE approaches of plagiarism detection, file-attribute-based, text-based, token-based, syntax-based and semantic-based. The prior three approaches have their own limitations, while the technique based on(More)
The improvement of electrochemical detection of meloxicam is presented by modification of a glassy carbon electrode with anionic layer of cysteic acid providing electrostatic accumulation of the analyte onto the electrode surface. The modification formed by electrochemical oxidation of L-cysteine was performed by cycling potential in cysteine solution. The(More)
Keywords: Cabin air quality In-flight sampling Volatile organic compounds (VOCs) Detection rate Impact factor Qualitative analysis a b s t r a c t To better understand the overall VOC species and levels and their key influencing factors in aircraft cabin, we conducted in-flight measurements in 107 commercial flights from August 2010 to August 2012. These(More)
Caffeoylquinic acids (CQAs) are main constituents in many herbal medicines with various biological and pharmacological effects. However, CQAs will degrade or isomerize when affected by temperature, pH, light, etc. In this study, high-performance liquid chromatography with photodiode array detection (HPLC-PDA) and high-performance liquid chromatography(More)
This paper analyzed the spreading effect of industrial sectors with complex network model under perspective of econophysics. Input-output analysis, as an important research tool, focuses more on static analysis. However, the fundamental aim of industry analysis is to figure out how interaction between different industries makes impacts on economic(More)
Recently, air pollution issues have drawn significant attention to the development of efficient air filters, and one of the most promising materials for this purpose is nanofibers. We explore here the mechanism of selective molecular capture of volatile organic compounds in carbon nanotube networks by performing atomistic simulations. The results are(More)
