Neural network ensemble has demonstrated many advantages over single neural networks in terms of generalization ability and parameters configuration. As compared to traditional bagging and boosting that are typical of generating individual network by horizontally partitioning training dataset, this paper proposes a new ensemble method called RRSE (rough(More)
Objective: To understand the distribution of Salmonella in external environment in Henan province, and explore the distribution of different serotypes of the Salmonella and their homology. Methods: A total of 4 488 samples were collected form animal dung, meat products and kitchen utensils, and identified by biochemical tests and serotyped by serum(More)
Objective: To analyze the serotypes and antibiotic resistance phenotypes of non-typhi Salmonella strains in Henan province from 2011 to 2015. Methods: The stool samples were collected from diarrhea patients, and enriched with SBG enrichment broth and the pathogen isolation was conducted with CHROMAgar selective culture medium at 37 ℃ for 18-24 hours using(More)
OBJECTIVE To analyze the distribution and pulsed field gel electrophoresis (PFGE) patterns of five kinds of diarrheagenic Escherichia coli (DEC) in infected diarrhea population of Henan province in 2013. METHODS Gathering 1 037 strains of E. coli of 1 037 diarrhea patients from four sentinel hospitals of multi-pathogen monitoring system in Henan province(More)
Objective: To investigate the infection status of human rotavirus, calicivirus, astrovirus and enteric adenovirus in children aged <5 years in disease surveillance areas in Henan province from 2013 to 2015. Methods: A total of 880 stool samples were collected from four sentinel hospitals and group A rotavirus was detected by ELISA and group A rotavirus G/P(More)
Today, Density Functional Theory (DFT) is one of the most widely applied electronic structure methods. Time Dependent DFT (TDDFT), which is an extension of DFT, can calculate the excitation properties of the systems. It has been used in physics, chemistry and biology researches. Known for its rigor, reliability, and efficiency, TDDFT is the method of choice(More)
Objective: To investigate the infectious status, gene type transition and epidemiological features of rotavirus A isolated from infants and children (<59 months-of-age) in sentinel hospitals from 2008 to 2015 in Henan province, China. Methods: In total, 2 541 stool samples (each 3- 5 ml) were collected from infants and children aged less than five years in(More)
OBJECTIVE To investigate the drug tolerance and PFGE patterns of Salmonella(S.)paratyphi A strains isolated from sentinel hospitals in Dengfeng, Henan province, during 2009-2015. METHODS Venous blood samples were collected from paratyphoid patients and cultured in double phase blood culture bottle. Suspicious strains were identified and used for(More)
