1An experimental analysis of situation awareness for cockpit display interface evaluation based on flight simulation显示文摘Aircraft cockpit display interface (CDI) is one of the most important human-machine interfaces for information perceiving. During the process of aircraft design, situation awareness (SA) is frequently considered to improve the design, as the CDI must provide enough SA for the pilot to maintain the flight safety. In order to study the SA in the pilot-aircraft system, a cockpit flight simulation environment is built up, which includes a virtual instrument panel, a flight visual display and the corresponding control system. Based on the simulation environment, a human-in-the-loop experiment is designed to measure the SA by the situation awareness global assessment technique (SAGAT). Through the experiment, the SA degrees and heart rate (HR) data of the subjects are obtained, and the SA levels under different CDI designs are analyzed. The results show that analyzing the SA can serve as an objective way to evaluate the design of CDI, which could be proved from the consistent HR data. With this method, evaluations of the CDI design are performed in the experimental flight simulation environment, and optimizations could be guided through the analysis.Wei Hengyang Zhuang Damin Wanyan Xiaoru Wang Qun 2013Chinese Journal of Aeronautics2013,26,4:23
2Concentration level and geographical distribution of nitrobenzene in Chinese surface waters显示文摘Nitrobenzene was reported to occur at relatively high concentrations in some Chinese surface water and to cause an environmental pollution event in 2005.To map the distribution of nitrobenzene in the Chinese surface water throughout China,surface water samples were collected from over 600 sites in the 7 major watersheds and three drainage areas.The samples were analyzed for concentration of nitrobenzene.Overall,nitrobenzene was more frequently detected at higher concentrations in the rivers of North Chin...Jijun, Gao Linghua, Liu Xiaoru, Liu Huaidong, Zhou Zijian, Wang Shengbiao, Huang 2008Journal of Environmental Sciences2008,20,7:9
3Measurement-based Frequency Dynamic Response Estimation Using Geometric Template Matching and Recurrent Artificial Neural Network显示文摘Understanding power system dynamics after an event occurs is essential for the purpose of online stability assessment and control applications.Wide area measurement systems(WAMS)based on synchrophasors make power system dynamics visible to system operators,delivering an accurate picture of overall operating conditions.However,in actual field implementations,some measurements can be inaccessible for various reasons,e.g.,most notably communication failure.To reconstruct these inaccessible measurements,in this paper,the radial basis function artificial neural network(RBF-ANN)is used to estimate the system dynamics.In order to find the best input features of the RBF-ANN model,geometric template matching(GeTeM)and quality-threshold(QT)clustering are employed from the time series analysis to compute the similarity of frequency dynamic responses in different locations of the power system.The proposed method is tested and verified on the Eastern Interconnection(EI)transmission system in the United States.The results obtained indicate that the proposed approach provides a compact and efficient RBF-ANN model that accurately estimates the inaccessible frequency dynamic responses under different operating conditions and with fewer inputs.Feifei Bai Xiaoru Wang Yilu Liu Xinyu Liu Yue Xiang Yong Liu 2016CSEE Journal of Power and Energy Systems2016,2,3:8
4Fabrication of organically modified oxygen sensing film based on fluorescent quenching显示文摘An organically modified silicate (ORMOSIL) as a matrix for oxygen-sensitive sensor, in which di-methyldimethoxysilane was selected as an organic modifier in the precursor, is described. The sensing film with tris-(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) as an indicator developed in this paper was characterized by efficient quenching by oxygen. Blue light-emitting diodes (λmax = 475 nm) were employed as light excitation source. The linear range of the dissolved oxygen was from 0.5 to 16 μg/mL. The measured RSD was 2%, the response time (t95) was 60 s, and the determination limit was 0.2 μg/mL. A portable and inexpensive luminescence-based sensor was established and applied to the determina-tion of dissolved oxygen in the surface water.XIN LingLing XIAO LaiLong ZHAO Li CHEN Xi WANG XiaoRu 2007Chinese Science Bulletin2007,52,2:4
5Loss of scleraxis leads to distinct reduction of mineralized intermuscular bone in zebrafish显示文摘Intermuscular bones(IBs)are ossified from tendons and only occur in lower teleosts.Positive association between the regulation of scleraxis gene(scx)and tendon development gave us reasons to speculate that the scx gene may play a potential role in regulating the development of IBs.A phylogenetic analysis conducted for this study revealed potential functional differentiation between two scx orthologues,scxa and scxb.The scxa^(-/-) and scxb^(-/-) zebrafish were generated through CRISPR-Cas9 technology to study the role of scx in the IB and rib development.The results showed a significant reduction of the number of IBs in adult scxa-1^(-/-) zebrafish,with almost 70%reduction(15-25 IBs)compared to the wild type scxa-1^(+/+)zebrafish(76-80 IBs).In the scxa-1^(+/+)adults,IBs were observed in both dorsal and tail segments;however,in scxa-1^(-/-)fish IBs were observed only in the tail segment(none in the dorsal segment).Although scxa-1^(-/-) zebrafish had rib defects,the mutants were viable and fertile as adult fish.The scxb^(-/-) zebrafish had the same number of IBs and same skeletal phenotype as the wild-type fish.This suggests that only scxa has a crucial role in the IB development,and confirms functional differentiation of scx orthologues.To further clarify the molecular mechanism by which scxa affects the IB development,we conducted comparative transcriptome analysis of dorsal tissue samples of scxa-1^(+/+)(with IBs)and scxa-1^(-/-) (without IBs),and further verified the expression of key genes via qPCR.This is the first study to identify a gene that controls the amount of IBs in fish,and it provides a new sight into the effects of scxa on the molecular mechanism of IB development in fish.Chunhong Nie Shiming Wan Yulong Chen Dejie Zhu Xudong Wang Xiaoru Dong Ze-Xia Gao 2021Aquaculture and Fisheries2021,6,2:3

7Corrosion Mechanism and Corrosion Model of Mg-Y Alloy in NaCl Solution显示文摘Corrosion of Mg–Y alloy was studied using electrochemical evaluations, immersion tests and SEM observations. Corrosion mechanisms of Mg-(0.25 and 2.5) Y alloy and Mg-(5, 8, and 15) Y alloy were uniform corrosion and pitting corrosion respectively, and the content of Mg_(24)Y_5 phases determined its effect acting as cathode to accelerate the corrosion or corrosion barrier to inhibit the corrosion. Corrosion resistance of Mg-(0.25, 2.5, 5, 8, and 15) Y alloys was as follows: Rt(Mg-0.25Y) < Rt(Mg-8Y) < Rt(Mg-15Y) < Rt(Mg-5Y) < Rt(Mg-2.5Y). Y could significantly improve the corrosion resistance of the Mg-Y alloy, but the excess of Y deteriorated the corrosion resistance of the Mg-Y alloy. The optimum content of Y in the studied alloys was 2.5%.徐宏 WU Zhiquan WANG Xiaoru 张新 REN Jiping SHI Yang WANG Zepu WANG Liwei LIU Changhua 2016Journal of Wuhan University of Technology(Materials Science)2016,31,5:3
8Enhanced removal of Cr(Ⅵ) by biochar with Fe as electron shuttles显示文摘Biochar is extensively used as an effective soil amendment for environmental remediation.In addition to its strong contaminant sorption capability, biochar also plays an important role in chemical transformation of contaminant due to its inherent redox-active moieties.However, the transformation efficiency of inorganic contaminants is generally very limited when the direct adsorption of contaminants on biochar is inefficient. The present study demonstrates the role of Fe ion as an electron shuttle to enhance Cr(Ⅵ) reduction by biochars. Batch experiments were conducted to examine the effects of Fe(Ⅲ) levels,pyrolysis temperature of biochar, initial solution pH, and biochar dosage on the efficiency of Cr(Ⅵ) removal. Results showed a significant enhancement in Cr(Ⅵ) reduction with an increase in Fe(Ⅲ) concentration and a decrease of initial pH. Biochar produced at higher pyrolysis temperatures(e.g., 700°C) favored Cr(Ⅵ) removal, especially in the presence of Fe(Ⅲ), while a higher biochar dosage proved unfavorable likely due to the agglomeration or precipitation of biochar. Speciation analysis of Fe and Cr elements on the surface of biochar and in the solution further confirmed the role of Fe ion as an electron shuttle between biochar and Cr(Ⅵ). The present findings provide a potential strategy for the advanced treatment of Cr(Ⅵ) at low concentrations as well as an insight into the environmental fate of Cr(Ⅵ) and other micro-pollutants in soil or aqueous compartments containing Fe and natural or engineered carbonaceous materials.Jingwen Xu Yongguang Yin Zhiqiang Tan Bowen Wang Xiaoru Guo Xia Li Jingfu Liu 2019Journal of Environmental Sciences2019,31,4:3

10Multivariate analysis of fluorescence and source identification of dissolved organic matter in Jiaozhou Bay, China显示文摘Hierarchical clustering analysis and principal component analysis (PCA) methods were used to as-sess the similarities and dissimilarities of the entire Excitation-emission matrix spectroscopy (EEMs) data sets of samples collected from Jiaozhou Bay, China. The results demonstrate that multivariate analysis facilitates the complex data treatment and spectral sorting processes, and also enhances the probability to reveal otherwise hidden information concerning the chemical characteristics of the dissolved organic matter (DOM). The distribution of different water samples as revealed by multivariate results has been used to track the movement of DOM material in the study area, and the interpretation is supported by the results obtained from the numerical simulation model of substance tracing technique, which show that the substance discharged by Haibo River can be distributed in Jiaozhou Bay.JIANG Fenghua YANG Baijuan LEE Frank Sen-Chun WANG Xiaoru CAO Xuail 2009Acta Oceanologica Sinica2009,28,2:2
11Contribution of Temperature Increase to Restrain the Transmission of COVID-19显示文摘The COVID-19 outbreak has already become a global pandemic and containing this rapid worldwide transmission is of great challenge.The impacts of temperature and humidity on the COVID-19 transmission rate are still under discussion.Here,we elucidated these relationships by utilizing two unique scenarios,repeated measurement and natural experiment,using the COVID-19 cases reported from January 23–February 21,2020,in China.The modeling results revealed that higher temperature was most strongly associated with decreased COVID-19 transmission at a lag time of 8 days.Relative humidity(RH)appeared to have only a slight effect.These findings were verified by assessing SARSCoV-2 infectivity under the relevant conditions of temperature(4C–37C)and RH(>40%).We concluded that temperature increase made an important,but not determined,contribution to restrain the COVID19 outbreak in China.It suggests that the emphasis of other effective controlling polices should be strictly implemented to restrain COVID19 transmission in cold seasons.Mengyuan Ren Rongjuan Pei Bahabaike Jiangtulu Junxi Chen Tao Xue Guofeng Shen Xiaoru Yuan Kexin Li Changxin Lan Zhen Chen Xinwen Chen Yun Wang Xiaoqian Jia Zewu Li Audil Rashid Tippawan Prapamontol Xiuge Zhao Zhaomin Dong Yali Zhang Le Zhang Rongwei Ye Zhiwen Li Wuxiang Guan Bin Wang 2021The Innovation2021,2,1:2
12Effect of Fanbaicao(Herba Potentillae Discoloris) oil on the expression of p21 and CDK4 in HepG2 cells显示文摘OBJECTIVE:To research the anti-cancer mechanism of the Traditional Chinese Medicine Fanbaicao(Herba Potentillae Discoloris) oil in the human hepatoma cell line Hep G2.METHODS:Gas chromatography was used to analyze the components of Fanbaicao(Herba Potentillae Discoloris).We tested the inhibitory effect of Fanbaicao(Herba Potentillae Discoloris) oil on the human hepatoma cell line Hep G2 in vitro using 3-(4,5-Dimet hylt hiazol-2-yl)-2,5-dip henyltetrazoliumbromide assays.Fluorescence activating cell sorter analysis was used to examine the levels of apoptosis,and western blot and immunofluorescence were used to detect the expression of p21,p-p21 and CDK4 proteins.RESULTS:Fanbaicao(Herba Potentillae Discoloris)oil contains 45 ingredients,and L-ascorbic acid 2,6-bispalmitate was the main component and accounted for 44.96% of total drive-off peak area.Other components included(Z)-14-met hyl-8-exadecenal-acetal(8.56%),phytol(7.74%) and lauric acid(6.31%).Fanbaicao(Herba Potentillae Discoloris)oil treatment reduced the proliferation of Hep G2 cells and the half growth inhibition concentration(IC50) was 2.03 mg/m L.Furthermore,we also observed significantly increased Hep G2 cell apoptosis in a dose-dependent manner(P < 0.05).Fanbaicao(Herba Potentillae Discoloris) oil significantly increased the expression of p21 and p-p21 and significantly decreased the expression of CDK4 in Hep G2 cells compared with controls(P < 0.01).CONCLUSION:Our results showed that Fanbaicao(Herba Potentillae Discoloris) oil has anti-cancer activities in Hep G2 cells,which is probably related to the upregulation of p21 and p-p21 and downregulation of CDK4 expression.Liu Lei Chen Guang Wang Baixin Chen Liping Wang Shuqiu Liu Zhixin Ma Xiaoru Wang Fangfang Liang Yanfeng Wu Jiamei Yang Zhiwei 2016Journal of Traditional Chinese Medicine2016,36,4:1
