Currently, accelerating education informatization still faces many difficulties and problems. Compared with the requirements of the CPC Central Committee and the State Council, and compared with the level of deep application and integration innovation in developed countries, there are still gaps and many problems. At present, cloud computing, big data, Internet of Things, mobile computing and other new technologies are gradually widely used, the pace of informatization in all sectors of the economy and society is accelerating, the overall level of informatization in society is deepening, and the revolutionary impact of information technology on education is becoming increasingly obvious. Under the general trend of such technology, the cloud platform of comprehensive business based on cloud computing technology will be planned and built in an overall way to provide strong support for medical teaching, scientific research, innovation and development of faculty and students of the university. The integrated business platform provides cloud services such as standard IT infrastructure, student training platform, medical teaching and research, scientific research and development, and "entrepreneurship and innovation". Students and teachers can access and use IT at any time through the network. The content of each service can be customized and expanded according to the requirements of teachers and students. With the promotion of the service, the audience can be extended from teachers and students to users outside the school.展开更多

With the continuous development of big data, university network security has also become a major concern. Therefore, this paper first introduces the characteristics of university network from the perspective of big data, and then introduces the security risks of university network from the perspective of big data, which can provide the corresponding solutions to these problems.展开更多

We conducted genome sequencing and phylogenetic analyses of SARS-CoV. Based on genome sequencing, we predicted the E protein is a transmembrane (TM) protein characterized by a TM region with strong hydrophobicity and α-helix conformation. We identified a segment (NH2-_L-Cys-A-Y-Cys-Cys-N_-COOH) in the carboxyl-terminal region of the E protein that appears to form three disulfide bonds with another segment of corresponding cysteines in the carboxyl-terminus of the S (spike) protein. These bonds point to a possible structural association between the E and S proteins. Our phylogenetic analyses of the E protein sequences in all published coronaviruses place SARS-CoV in an independent group in Coronaviridae and suggest a non-human animal origin.展开更多
