Naive Bayes algorithm is uncomplicated and effective in text classification and experiments. However, its performance is often imperfect because it does not model text well, and by inappropriate feature selection and some disadvantages of the Naïve Bayes itself. This paper makes some modifications for Naive Bayes to improve the performance of(More)
MicroRNAs (miR, miRNAs) play pivotal roles in numerous physiological and pathophysiological contexts. We investigated whether miR-362-5p act as an oncogene in chronic myeloid leukaemia (CML) and aimed to understand its potential underlying mechanisms. We compared the miR-362-5p expression levels between CML and non-CML cell lines, and between fresh blood(More)
Humic acid (HA) and fulvic acid (FA) extracted from landfills at different landfill ages were characterized by elemental composition, (13)C CP/MAS NMR, and TMAH-Py-GC/MS. The elemental composition analysis revealed high O/C and low H/C ratios in the FA, indicating a high proportion of O-alkyl and carboxylic acids in the FA. The analytical results of (13)C(More)
OBJECTIVE To observe the effect of Sancaijiangtang powders on plasma nitric oxide and endothelin-1 levels. We sought to identify the common pathological link and mechanism of action for Traditional Chinese medicine in type 2 diabetes mellitus and vascular dementia, and to explicate the material basis for treating the different diseases with the same method(More)

An effective feature selection is very important for an classifier. Improved feature selection method can enhance its classifier efficiency in the practical test validates. This paper studies the principle·, merits and limitations of the prevalent feature selection method. Then, the paper adopts two-stage selection modulus which is calculated by the(More)
The current practice of recognition spectra manually is no longer applicable to a large extent. This work is particularly focused on helping astronomers finding their interesting celestial objects. In this paper an efficient hierarchical clustering data mining method based on principal component analysis (PCA) is proposed. Massive stellar spectral data are(More)
To assess the reclamation feasibility of a landfill, the characteristics, distribution, and mobility of heavy metals in the landfill were investigated. The refuse was characterized as containing high concentrations of heavy metals, a relatively high pH, and a high ratio of NH(4)-N to total nitrogen (TN). The results of heavy metal distribution showed that(More)
Our results prove the local origin of magnetoresistance in electrochemically deposited Ni nanocontacts. Experiments have been done using a complex setup for both in situ growth and ballistic magnetoresistance ~BMR! measurements. Nanocontacts have been grown between two macroscopic Ni wires. In situ experiments with variation of the nanocontact diameter from(More)
This paper describes a design of video control system based on Texas Instruments's USB controller TUSB3210. According to the TUSB3210, the system realizes the initialization of registers of the PAL/NTSC decoder SAA7113H and the PAL/NTSC encoder SAA7121H through the IIC-bus, and realizes the program in system for the full system. As the video-part of the(More)
