A Study on the Evolution of Mechanism of Infectious Disease Analysis Model of Event Using Micro-Blog Platform  [PDF]
Haiying Ma
Social Networking (SN) , 2015, DOI: 10.4236/sn.2015.43011
Abstract: After the occurrence of unexpected group events of network, the relevant opinion information will spread rapidly through micro-blog, and the negative public opinion information will aggravate the unexpected the group events to upgrade and expand the scope of harm. It is difficult to deal. So public opinion control is very important. In this paper, we establish an influence model for spreading of public opinion based on SIR model. Through the political analysis, this paper finds that the network group events will subside, but the influence scope, time and ability of event cannot be ignored. As a result of this study, the corresponding strategies are put forward in this paper.
Research of Evolution Mechanism of Network Group Event Based on Grounded Theory under Micro-Blog Platform  [PDF]

Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.85069
Abstract: At this stage, China society in conflict-prone period, the network group events developed rapidly. Network group events had a significant impact on society. The trend which the online group event evolved into the offline group incidents is becoming evident. In this paper, we used grounded theory to study the evolution and the development process of network group events under the micro-blog platform. We present an evolution mechanism model of network group event under micro-blog platform and find the formation mechanism of the network of public opinion, intrinsic motivation and the evolution of the network group events.

In this paper, a comprehensive model is proposed, which is based on generalized association rules and decision tree technology. The model is used for customer segmentation of e-commerce website. It can help e-commerce companies understand customers, support decision-making, so as to provide customers with more targeted services.
Research on Network Group Event Recognition Based on Neural Network  [PDF]
Haiying Ma
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.412008
Abstract: Sina Weibo is one of China’s most popular SNS platforms, which has a large number of user groups. Nowadays, the public opinion on Sina Weibo has great influence and significantly affects the social reality. This paper defines the network group events from aspects of the nature of the incident and influence and establishes a neural network of pattern recognition model that is used to fit the model. The model can recognize the network group events through continuous three days’ various topics growth rate. By programing a crawler, we get the data of 23 hot events on Sina Weibo from 2011 to 2015 for neural network training. The training results of pattern recognition model show that the accuracy rate of the judgment of the Internet Group events and the non-network group events is 72.7% and 75% respectively. The overall accuracy was 73.9%.
Calculation of non-mono chromatic reflectance of Co/Sb multilayer
Shimeng Feng,Haiying Zhao,Jianda Shao,Zhenxiu Fan,Xiaoming Dou
Chinese Science Bulletin , 2003, DOI: 10.1007/BF03184075
Abstract: Co/Sb multilayer shows the theoretical reflectance of 62% at a photoenergy of 528 eV and the grazing angle of 10.3°, but the measured reflectance is very low, which is considered to result from the low energy resolution of the incidence light. In this paper we have investigated the effect of the energy resolution of the incidence light on the measured reflectance, and show a new method how to calculate the reflectance of non-monochromatic light. The calculated data show that the reflectance of Co/Sb multilayer is very sensitive to the effect of the energy resolution of the incidence light. Generally, it is very low unless the energy resolution of the incidence light is high enough. Using our method, we give the fitted result of the reflectance spectrum. Our fitted result is consistent with the measured reflectance spectrum.
Analysis of Network Security and Risks Prevention Strategies of Hongqiao Airport West Terminal
Chongjun Fan,Honglin Xiong,Haiying Zhang,Wujun Liu
Computer and Information Science , 2009, DOI: 10.5539/cis.v2n3p46
Abstract: The sharing and openness of network are convenient to the airport operations and passenger information inquiry, but also result in information security issues. In the design of Hongqiao Airport West Terminal network system, information security issues have been taken as important topics, and preventive strategies which aim at the specific circumstances have been formulated by comprehensive analyzing the causes of potential security hazard of airport network system security. This project can provide reference and help to related Chinese airport’s planning and construction projects.
Role of Tat-Mediated PDZ Peptide Delivery in Pain Therapy  [PDF]
Haiying Wu, Feng Tao
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.225071
Abstract: Delivery of therapeutic peptides or proteins into tissues is severely limited by the size and biochemical properties of the molecules. Protein transduction domain (PTD)-mediated cargo transduction represents a novel and promising strategy to deliver biologically active peptides in vivo. The first PTD was identified from the HIV-1 transactivating transcriptional activator protein Tat in 1988. Since then, other PTDs have also been identified, including the third α-helix of the antennapedia homeotic transcription factor and synthetic peptide carriers. However, Tat PTD (amino acids 47 - 57) has shown markedly better ability for intracellular delivery than other PTDs. It has been demonstrated that fusion peptides containing the Tat PTD enter the central nervous system after systemic administration. Our previous study has shown that i.p. injected Tat-PSD-95 PDZ2 expresses in the central nervous system and significantly disrupts PDZ domain-mediated protein interactions between PSD-95 and N-methyl-D-aspartate receptor subunit NR2A/2B, thereby alleviating chronic pain. Therefore, Tat-mediated intracellular delivery can be used for systemic administration of analgesics in pain management.
Chemistry Education in Talent Training of Mineral Processing Engineering Disciplines Paper  [PDF]
Shuming Wen, Haiying Shen
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.37B044
Abstract: In mineral processing engineering disciplines, flotation, as a primary beneficiation method, is performed on the basis of surface chemical properties of minerals and rocks. The surface chemistry of minerals and rocks can be artificially changed to achieve minerals flotation separation. Thus chemistry plays a very important role in mineral processing engineering disciplines. Analysis shows that inorganic chemistry, organic chemistry and physical chemistry are all required courses for undergraduate students majoring in mineral processing engineering. Analytical chemistry and further quantum chemistry for advanced talent training at the graduate education level are necessary. Chemistry lays the foundation for realizing resource use in efficiency, integration and cleanliness, and plays a significant role in wastewater recycling, zero discharge and environment protection. Emphasizing chemistry education and improving chemistry expertise are an important guarantee for environment protection and sustainable development of mineral resources exploitation and utilization.

Haiying Hu, Huamao Huang
Energy and Power Engineering (EPE) , 2013, DOI: 10.4236/epe.2013.54B009
Abstract: The evolution of monthly runoff is affected both by climate environment and human activities, and its characteristics play an important role in runoff prediction and simulation. In this paper, the G-P and the principal component analysis method, which are both based on the reconstruction theory of the phase space, are used to study the chaos characteristics of the monthly runoff series at Fudedian station in Liaohe basin. The results show that the monthly runoff series have a large probability of chaos.

Abstract: In recent years, brand crises are becoming increasingly prevalent in the global marketplace. Given that brand crises have many devastating effects, how to manage them effectively has become a hot topic among marketing researchers and practitioners. Based on the review of literatures concerned, this paper first analysed the concept and types of brand crises. Then this article summarized the response strategies that corporations can take during that hard time. Furthermore, this paper identified some factors that influence the effectiveness of those response strategies. Given all of this, the review highlights some promising directions for future research.
