The case-based reasoning (CBR) becomes a novel paradigm that solves a new problem by remembering a previous similar situation and by reusing information and knowledge of that situation. However, the acquisition of case knowledge is a bottleneck within case-based reasoning. The use of rough set and data mining to discover knowledge from traditional database(More)
A modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for the simultaneous determination of spirotetramat and its four metabolites in fruits (apple, peach) and vegetables (cabbage, tomato, potato, cucumber), based on the use of liquid extraction/partition and dispersive solid phase extraction (dispersive-SPE) followed by(More)
Biochars can significantly sorb pesticides, and reduce their bioavailability in agricultural soils. In this study, the effects of a type of biochar (BC500) on the sorption, degradation, bioaccumulation and bioavailability of thiacloprid, which is a commonly used insecticide, were investigated. The thiacloprid sorption constant (Kf values) increased by 14(More)
Dysfunction of pancreatic beta-cells is a fundamental feature in the pathogenesis of type 2 diabetes. As insulin receptor signaling occurs via protein tyrosine kinase (PTK), we investigated the role of PTK activity in the etiology of beta-cell dysfunction by inhibiting PTK activity in primary cultured mouse pancreatic beta-cells and INS-1 cells with(More)
The presence of small amounts of boron in ductile iron is reported to have multiple and sometimes conflicting effects on the mechanical properties of ductile irons. The technical literature up until the early 1990’s states that small amounts of boron is a powerful carbide stabilizing element. Boron levels as low as 0.001% (10 ppm’s or parts per million)(More)
An effective method for the quantification of fluxapyroxad and its three metabolites in soils, sediment and sludge was developed using ultrahigh performance chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS). Both the extraction and clean-up steps of the QuEChERS procedure were optimised using a chemometric tool, which was expected to(More)
This paper reported a rotational positioning method based on the microscopic vision. Rotational positioning method has important applications in image scanning of biological tissue or cell injection experiments. A compact rotational stage driven by a stepper motor is utilized, and cross mark alignment method with unequal length is proposed to aid(More)
In view of word sense disambiguation shortcomings of the previous methods, they generally do not consider on word distance for computing semantic correlation of the influence of context, as well as the context is limited for ambiguous word sense disambiguation, and the use of part ambiguous context words make word senses more ambiguous. Therefore, this(More)
