The bovine viral diarrhea virus (BVDV), a single-stranded RNA virus, can cause fatal diarrhea syndrome, respiratory problems, and reproductive disorders in herds. Over the past few years, it has become clear that the BVDV infection rates are increasing and it is likely that an effective vaccine for BVDV will be needed. In this study, transgenic Astragalus(More)
Bovine viral diarrhea virus (BVDV) infections are endemic in cattle populations worldwide and cause major economic losses. Thus, an effective vaccine is needed against the transmission of BVDV. The glycoprotein Erns is one of the envelope proteins of this virus and shows BVDV-related immunogenicity. Here, we report the use of Panax ginseng as an alternative(More)
—Precision agriculture is the frontier of international contemporary agriculture in the twentieth century. The development of precision agriculture is a significant strategic choice of agriculture and agricultural science development in the new stage in China. As a novel technology of information acquisition and processing, WSN possesses a great strategic(More)
In view of the imperfection of the Android operating system multimedia function and the complexity of streaming media system. At the same time, the development cycle is long, and efficiency is low. In order to solve those problems, the thesis designed the streaming engine layer between Linux kernel layer and application framework layer of Android platform,(More)
The Wireless Sensor Network technology has been used widely; however the limited energy resource is one of the bottlenecks for its application. To enhance the robustness and accuracy of the information which is obtained by the entire network, certain redundancy exists in the data collected from the sensor node and thus data fusion processing is needed to(More)
This paper investigates the productivity and collaborations patterns in the publications of IEEE Transactions on Intelligent Transportation Systems (T-ITS) between 2010 and 2013. Our findings show that industry is playing a more important role in research cooperation. Such a trend is particularly beneficial for expediting the commercialization of scientific(More)
Piezoelectric actuator is widely used in precision positioning mechanism for the advantages of ultra high resolution, high response frequency and rapid dynamic performance. But the displacement error is conducted for the inherent hysteretic nonlinear characteristics, and the tracking precision is limited. A modified modeling method combining the neural(More)
