Chemical cleaning and disinfection are crucial steps for eliminating infection in root canal treatment. However, irrigant selection or irrigation procedures are far from clear. The vapor lock effect in the apical region has yet to be solved, impeding irrigation efficacy and resulting in residual infections and compromised treatment outcomes.

作者： Ma Xuejiao Lu Shenning Ding Wei Deng Shanying Wang Duoquan Xiao Ning Mlacha Yeromin Husain Lewis Zhou Xiaonong National Institute of Parasitic Diseases Chinese Center for Disease Control and Prevention (Chinese Center for Tropical Diseases Research) NHC Key Laboratory of Parasite and Vector Biology WHO Collaborating Center for Tropical Diseases National Center for International Research On Tropical Diseases Shanghai China university of Hong Kong Hong Kong China school of Global Health Chinese Center for Tropical Diseases Research Shanghai Jiao Tong University School of Medicine Shanghai China Ifakara Health Institute Dar-es-Salaam Tanzania Institute of Development Studies Brighton UK

Tripartite partnership, compared with the bilateral model, is envisioned as an opportunity to foster stronger and more trusting partnerships [1]. However, China has historically been characterized as principally reliant on bilateral engagement in global health [2]. The China-Tanzania Cooperation Project on Malaria Control was conducted by National Institute of Parasitic Diseases at China CDC and Chinese Center for Tropical Diseases Research, Ifakara Health Institute in Tanzania and funding agencies from 2015 to 2022, with an aim to explore the applicability of Chinese experience on malaria control to reduce malaria disease burden in the local context of Tanzania. In the tripartite project funded by the former UK Department for International Development (DFID) and later the Bill & Melinda Gates Foundation (BMGF), China's partners were expected to share the extensively parallel practices achieved from the control and elimination of malaria for over 70 years, UK's partners were to deliver resources and design global health strategies, while Tanzanian local staff collaborated with triangular partners to ensure the project implementation [3]. In the project, the trilateral cooperation has transparent management mechanism to ensure the concrete management and implementation of the project [4] (Additional file 1: Figure S1). This Brief is to provide recommendations for China's engagement in global health by distilling the experience from the innovative tripartite partnership of the project.

Epidemic Spreading in Contact Networks Based on Exposure Level

引用

Chinese Physics Letters 2006年第5期23卷 1347-1350页

作者：段文奇陈忠刘曾荣 school of management Shanghai Jiao Tong University Shanghai 200052 Department of Mathematics Shanghai University Shanghai 201800

Most epidemic models for the spread of diseases in contact networks take the assumption of the infected probability of a susceptible agent dependent on its absolute number of infectious neighbours. We introduce a new epidemic model in which the infected probability of a susceptible agent in contact networks depends not on its degree but on its exposure level. We find that effective average infection rate ^-λ （i.e., the average number of infections produced by a single contact between infected individuals and susceptible individuals） has an epidemic threshold ^λc = 1, which is related to recovery rate, epidemic mechanisms and topology of contact network. Furthermore, we show the dominating importance of epidemic mechanisms in determining epidemic patterns and discussed the implications of our model for infection control policy.

MapReduce Based Parallel Bayesian Network for Manufacturing Quality Control

引用

Chinese Journal of Mechanical Engineering 2017年第5期30卷 1216-1226页

作者： Mao-Kuan Zheng Xin-Guo Ming Xian-Yu Zhang Guo-Ming Li school of Mechanical Engineering Shanghai Jiao Tong University

Increasing complexity of industrial products and manufacturing processes have challenged conventional statistics based quality management approaches in the cir- cumstances of dynamic production. A Bayesian network and big data analytics integrated approach for manufacturing process quality analysis and control is proposed. Based on Hadoop distributed architecture and MapReduce parallel computing model, big volume and variety quality related data generated during the manufacturing process could be dealt with. Artificial intelligent algorithms, including Bayesian network learning, classification and reasoning, are embedded into the Reduce process. Relying on the ability of the Bayesian network in dealing with dynamic and uncertain problem and the parallel computing power of MapReduce, Bayesian net- work of impact factors on quality are built based on prior probability distribution and modified with posterior probability distribution. A case study on hull segment manufacturing precision management for ship and offshore platform building shows that computing speed accelerates almost directly pro- portionally to the increase of computing nodes. It is also proved that the proposed model is feasible for locating and reasoning of root causes, forecasting of manufacturing outcome, and intelligent decision for precision problem solving. The inte- gration ofbigdata analytics and BN method offers a whole new perspective in manufacturing quality control.

Optimization design of the stratospheric airship's power system based on the methodology of orthogonal experiment

引用

Journal of Zhejiang university-Science A(Applied Physics & Engineering) 2013年第1期14卷 38-46页

作者： Jian LIU Quan-bao WANG Hai-tao ZHAO Ji-an CHEN Ye QIU Deng-ping DUAN school of Aeronautics and Astronautics Shanghai Jiao Tong University

The optimization design of the power system is essential for stratospheric airships with paradoxical requirements of high reliability and low weight. The methodology of orthogonal experiment is presented to deal with the problem of the optimization design of the airship's power system. Mathematical models of the solar array, regenerative fuel cell, and power management subsystem (PMS) are presented. The basic theory of the method of orthogonal experiment is discussed, and the selection of factors and levels of the experiment and the choice of the evaluation function are also revealed. The proposed methodology is validated in the optimization design of the power system of the ZhiYuan-2 stratospheric airship. Results show that the optimal configuration is easily obtained through this methodology. Furthermore, the optimal configuration and three sub-optimal configurations are in the Pareto frontier of the design space. Sensitivity analyses for the weight and reliability of the airship's power system are presented.

Poor rich demarcation of Matthew effect on scale-free systems and its application

引用

Chinese Physics B 2011年第4期20卷 27-32页

作者：闫栋董明 Abdelaziz Bourasc 于随然 school of Mechanical Engineering Shanghai Jiao Tong University College of Economics & management Shanghai Jiao Tong University IUT Lumière Technology Institute Université Lumière Lyon 2

In a scale-free network, only a minority of nodes are connected very often, while the majority of nodes are connected rarely. However, what is the ratio of minority nodes to majority nodes resulting from the Matthew effect？ In this paper, based on a simple preferential random model, the poor-rich demarcation points are found to vary in a limited range, and form a poor-rich demarcation interval that approximates to k/m E [3,4]. As a result, the （cumulative） degree distribution of a scale-free network can be divided into three intervals： the poor interval, the demarcation interval and the rich interval. The inequality of the degree distribution in each interval is measured. Finally, the Matthew effect is applied to the ABC analysis of project management.
