Osteopontin (OPN) is a kind of phosphorylated acidic glycoprotein, human beings' osteoclasts, macrophages, T cells, and vascular smooth muscle cells can secrete OPN, the gene is located on chromosome 4q13. OPN has a function of adhesion to protein, which can be combined with CD44, integrin v 3 and v...

Moving objects detection is an important research content in computer vision field and it plays a very important role in many vision applications such as smart video surveillance, intelligent transportation, and human-computer interaction, traffic control, activity recognition, object tracking and behavior...

The fetal heart rate (FHR) is a significant indicator of whether the fetus in the mother's womb is healthy. Ultrasonic Doppler detection is extensively used in the detection of FHR due to its high sensitivity, good directivity, and non-invasiveness. However, analog multiplier demodulation is usually...

Based on OpenGL and Google library we established the target model library and the canny operator is used for edge detection. Combined with D-S evidence theory and Pseudo-Zernike moments, the air target recognition algorithm based on information fusion is proposed. Pseudo-Zernike moments are invariant...

The immobilization of lactase is a more attractive approach to overcome the disadvantage of the free lactase. In the presented work magnetic Fe304 fluid was synthesized by chemical coprecipitation and its surface was modified with sodium oleate. Then the liquid paraffin was used as dispersant and glutaraldehyde...

Based on the background of a double line shield tunnel in Shenyang metro, the construction process of double line shield is simulated by using the finite element analysis software of GTS Midas. The change course of ground surface settlement during construction and the influence of the physical and mechanical...

The similarity between different subcategories and scarce training data due to the difficulties of Fine-grained recognition. Even in the same subcategories, there can be some differences due to the distinct color and pose of objects. We propose some models for fine-grained plant recognition by taking...

This paper sets the three bilateral trade flows (1999-2014) as the basis of analysis and adds trade system arrangement policy variable within the classical trade gravity model. It also constructs the panel data model of three bilateral trade between China,Russia and Mongolia. The empirical results show...

This study explores factors that affect university teacher job satisfaction in Beijing. A quantitative approach was applied among 123 teachers of Beijing International Studies University. The result indicate that there are 3 main factors that affect teacher job satisfaction in Beijing, including working...

Ever since practicing the policy of reformation and opening, the economic development of Guangdong province has roughly experienced the three stages: the take-off stage (1979-1991),the accelerating development stage (1992-2002) and the scientific development stage (2003-now). Guangdong Province has made...

Basing on scene analysis and VaR calculation, this paper discussed system architecture of scenario calculation and accurate data's importance of system model from the view of system theory. We also discussed several kinds of data errors and their processing methods to avoid the error of data. Then we...

This paper inspects the effects of structural reforms of the mainland on the cross-strait economic and trade exchanges between 1995 and 2014. The research focuses on four fields: the institutional reform, the reform of the financial sector, the reform of the labor market, and the reform of the trading...

To investigate the academic status of students and to analyze the trend of students' academic achievement in a new local college of medicine and probes into the key control factors that affect the students' academic failure. Academic cleaning, questionnaire investigation and interview were used to analyze...

China's social development has entered a new era. The main idea of "Some opinions on deepening to streamline government functions and administration, delegate powers while improving regulation for higher education " is consistent with the spirit of the Nineteenth National Congress in China. Guided by...

Recitation--the traditional teaching method should be taken seriously again in English teaching. This is a survey report on the role of recitation in college art students' English learning. The research questions are: (1) Do you think recitation is useful for improving English? (2) Which recitation materials...
