If the MRS receives accident alarm information, the group of robots will navigate to the accident sites and provide corresponding emergency services.According to the characteristics of the MRS, a distributed consensus formation protocol is designed, which can assure that the multiple robots arrive at the accident site in a specified formation. The prototype emergency service system was designed and implemented, and some relevant simulations and experiments were carried out. The results showthat the MRS can successfully provide emergency lighting and failure node replacement services when accidents happen. The effectiveness of the algorithm and the feasibility of the system are verified.展开更多

The study of these unique diseases in China is hampered by a lack of resources. Amongst the most important resources for biological study are monoclonal antibodies. Here, we characterize a panel of monoclonal antibodies specific for cellular prion protein by enzyme-linked immunosorbent assay(ELISA), immunofluorescent staining, flow cytometry, and western blotting. We identify several antibodies that can be used for specific applications and we demonstrate that there is no prion protein expression in human pancreatic ductal epithelial cells(HPDC).展开更多

The outbound tourism behavior of Individual citizen is not only considered as the outward manifestation of individual civil quality, but also considered as the emblem the quality of all citizens of whole country, affects the national image, related to the country＇s national influence and credibility. The outbound tourism of Chinese citizens brought about the rapid growth of the enormous economic benefits and influence, which makes the outbound tourism behavior of Chinese citizens gotten more concern. The uncivilized outbound tourism behavior of Chinese citizens are frequent, which brings extremely strong damage, and which serious impact on the healthy image about the Ancient civilization and the country of ceremonies of China, and which greatly restricts the spread of a good national image of China. Based on the analysis about the characteristics of rapid growth outbound tourism of Chinese citizens, this paper discusses the approaches of current Chinese national image shaping, put forward that China must strengthen citizen education, and improve relevant laws and regulations, and strengthen supervision, only then might Chinese citizens outbound tourism uncivilized behavior be prevented from the root.展开更多

The optics sensors can get the illumination information of each light, the ranging radar gets the distance information, and then data amalgamation technology is used to compute the luminous intensity of each light. A method to modify the errors of this dynamic detection system is presented. It avoids the accumulation error and measurement carrier’s excursion error by using peak value detection based on optics sensors to estimate the accurate position of each light, then to modify the lights’ lengthways distance information and transverse position information. The performance of the detection and ranging system is validated by some experiments and shown in pictures.展开更多
