The female-biased infection of facultative symbionts has been found in Bemisia tabaci; however, whether there are any differences in tomato yellow leaf curl virus (TYLCV) and obligate symbiont infection rates between females and males is unknown. Determining whether such differences exist would be very important for understanding the spread of the plant(More)
Three Gorges Project is the world's largest hydropower station, and it is also China's largest hydraulic project. It has the very important role of flood control, generation and shipping. Poyang Lake is the largest freshwater lake of China. It has the natural role of regulating Yangtze River's water. It also provides a very good natural condition for the(More)
Although mitogenomes are useful tools for inferring evolutionary history, only a few representative ones can be used for most Ensifera lineages. Thirty-two ensiferan mitogenomes were determined using ABI Sanger sequencing and standard primer walking of 2-3 overlapping Long-PCR fragments, or Illumina® HiSeq2000 for "shotgun" sequenced long-PCR-amplified(More)
Pseudomonas sp. strain TXG6-1, a chitinolytic gram-negative bacterium, was isolated from a vegetable field in Taixing city, Jiangsu Province, China. In this study, a Pseudomonas chitinase C gene (PsChiC) was isolated from the chromosomal DNA of this bacterium using a pair of specific primers. The PsChiC gene consisted of an open reading frame of 1443(More)
Poyang Lake is China's largest freshwater lake. It has good regulation role to Yangtze River. After the running of Three Georges Project, it influences the water level of Poyang Lake a lot. This paper predicts Poyang Lake’s water level, it is the basic of influence research. Once there were many predicting methods, such as ANN, etc. But these(More)
In modern industry, data has become an indispensible resource for the whole process of production and business. For the optimization of the control performance, the data-driven PID controller is introduced in this paper. Based on the data-driven control law, the parameters of the PID controller will be renewed automatically by using the real and historical(More)
Morphological and molecular identification of aphid species We attempted morphology based identification of all experimental clones using published binomial keys (Heie 1994; Blackman and Eastop 2000). Simultaneously, we attempted their molecular identification by amplifying and sequencing a part of the mitochondrial cytochrome oxidase subunit I (COI) gene,(More)
Collaborative Filtering (CF) has become one of the most successful approaches for providing personalized product recommendations to users. Neighborhood-based CF is one of the main forms among all CFs, which is widely used in commercial domain. However, neighborhood-based CF suffers from new user cold-start problem in sparse rating data. In this paper, we(More)

Towards the needs of retrieving mathematical formulas, this paper details the semantic descriptors of MathML by utilizing the extensibility of XML and the characteristics of mathematical formulas through the analysis of the existing mathematical formula marking languages. We define a description attribute on the basis of MathML for conversion and retrieval(More)
