| 4 | A RISK ASSESSMENT METHOD OF THE WIRELESS NETWORK SECURITY显示文摘The core of network security is the risk assessment. In this letter,a risk assessment method is introduced to estimate the wireless network security. The method,which combines Analytic Hier-archy Process (AHP) method and fuzzy logical method,is applied to the risk assessment. Fuzzy logical method is applied to judge the important degree of each factor in the aspects of the probability,the influence and the uncontrollability,not to directly judge the important degree itself. The risk as-sessment is carved up 3 layers applying AHP method,the sort weight of the third layer is calculated by fuzzy logical method. Finally,the important degree is calculated by AHP method. By comparing the important degree of each factor,the risk which can be controlled by taking measures is known. The study of the case shows that the method can be easily used to the risk assessment of the wireless network security and its results conform to the actual situation. | Zhao Dongmei Wang Changguang Ma Jianfeng | 2007 | Journal of Electronics(China)2007，24，3： | 11 |
| 5 | △P index with different gas compositions for instantaneous outburst prediction in coal mines显示文摘In this study we measured the △P(initial speed of gas emission) index with different gas concentrations of carbon dioxide(pure CO2,90% CO2+10% CH4,67% CO2+33% CH4,50% CO2+50% CH4,30% CO2+10% CH4 and pure CH4) of coal samples from the No.2 coal seam in the Yaojie Coal Mine,Gansu province,China.The effect of carbon dioxide concentration,gas composition,coal strength and particle size of coal samples on the △P index was investigated.The experimental results show that with gas of various compositions,the △P value of three samples were clearly different.The △P index of coal samples A,B and C(0.2~0.25 mm) were 4,6 and 7 with pure CH4 and 22,30 and 21 when pure CH4 was used.Carbon dioxide concentration affects the △P index markedly.The △P index increases with an increase in carbon dioxide concentration,especially for coal B.Hence,the △P index and K(another outburst index) values tested only with pure CH4 for prediction of the danger of outburst is not accurate.It is important to determine the initial speed of gas emission given the gas composition of the coal seam to be tested for exact outburst prediction. | WU Dongmei ZHAO Yuemin CHENG Yuanping AN Fenghua | 2010 | Mining Science and Technology2010，20，5： | 10 |

| 10 | Correlation of Gut Microbiome Between ASD Children and Mothers and Potential Biomarkers for Risk Assessment显示文摘Variation of maternal gut microbiota may increase the risk of autism spectrum disorders(ASDs) in offspring. Animal studies have indicated that maternal gut microbiota is related to neurodevelopmental abnormalities in mouse offspring, while it is unclear whether there is a correlation between gut microbiota of ASD children and their mothers. We examined the relationships between gut microbiome profiles of ASD children and those of their mothers, and evaluated the clinical discriminatory power of discovered bacterial biomarkers. Gut microbiome was profiled and evaluated by 16S ribosomal RNA gene sequencing in stool samples of 59 mother–child pairs of ASD children and 30 matched mother–child pairs of healthy children. Significant differences were observed in the gut microbiome composition between ASD and healthy children in our Chinese cohort. Several unique bacterial biomarkers, such as Alcaligenaceae and Acinetobacter, were identified. Mothers of ASD children had more Proteobacteria, Alphaproteobacteria, Moraxellaceae, and Acinetobacter than mothers of healthy children. There was a clear correlation between gut microbiome profiles of children and their mothers; however, children with ASD still had unique bacterial biomarkers, such as Alcaligenaceae, Enterobacteriaceae, and Clostridium. Candidate biomarkers discovered in this study had remarkable discriminatory power. The identified patterns of mother–child gut microbiome profiles may be important for assessing risks during the early stage and planning of personalized treatment and prevention of ASD via microbiota modulation. | Ning Li Junjie Yang Jiaming Zhang Cheng Liang Ying Wang Bin Chen Changying Zhao Jingwen Wang Guangye Zhang Dongmei Zhao Yi Liu Lehai Zhang Jun Yang Guimei Li Zhongtao Gai Lei Zhang Guoping Zhao | 2019 | Genomics, Proteomics & Bioinformatics2019，17，1： | 6 |

| 14 | TCP7 functions redundantly with several Class Ⅰ TCPs and regulates endoreplication in Arabidopsis显示文摘TCP(TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR) proteins, a family of plantspecific transcription factors, play important roles in many developmental processes. However, genetic and functional redundancy among class I TCP limits the analysis of their biological roles. Here, we identified a dominantnegative mutant of Arabidopsis thaliana TCP7 named leaf curling-upward(lcu), which exhibits smaller leaf cells and shorter hypocotyls than the wild type, due to defective endoreplication. A septuple loss-of-function mutant of TCP7, TCP8, TCP14, TCP15, TCP21, TCP22, and TCP23 displayed similar developmental defects to those of lcu.Genome-wide RNA-sequencing showed that lcu and the septuple mutant share many misexpressed genes.Intriguingly, TCP7 directly targets the CYCLIN D1;1 (CYCD1;1) locus and activates its transcription. We determined that the C-terminus of TCP7 accounts for its transcriptional activation activity. Furthermore, the mutant protein LCU exhibited reduced transcriptional activation activity due to the introduction of an EAR-like repressive domain at its C-terminus. Together, these observations indicate that TCP7 plays important roles during leaf and hypocotyl development, redundantly, with at least six class I TCPs, and regulates the expression of CYCD1;1 to affect endoreplication in Arabidopsis. | Guofang Zhang Hongtao Zhao Chunguang Zhang Xiaoyun Li Yuanyuan Lyu Dongmei Qi Yanwei Cui Lin Hu Zhenjie Wang Zheng Liang Sujuan Cui | 2019 | Journal of Integrative Plant Biology2019，61，11： | 5 |
| 15 | Cardiomyocyte-like differentiation of human bone marrow mesenchymal stem cells after exposure to 5-azacytidine in vitro显示文摘Objective To investigate the potential of adult mesenchymal stem cells (MSCs) derived from human bone marrow to undergo cardiomyogenic differentiation after exposure to 5-azacytidine (5-aza) in vitro. Methods A small bone marrow aspirate was taken from the iliac crest of human volunteers, and hMSCs were isolated by 1.073g/mL Percoll and propagated in the right cell culturing medium as previously described. The phenotypes of hMSCs were characterized with the use of flow cytometry. The hMSCs were cultured in cell culture medium (as control) and medium mixed with 5-aza for cellular differentiation. We examined by immunohistochemistry at 21 days the inducement of desmin, cardiac-specific cardiac troponin I (cTnI), GATA 4 and connexin-43 respectively. Results The hMSCs are fibroblast-like morphology and express CD44+ CD29+ CD90+ / CD34- CD45- CD31- CD11a. After 5-aza treatment, 20-30% hMSCs connected with adjoining cells and coalesced into myotube structures after 14days. Twenty-one days after 5-aza treatment, immunofluorescence showed that some cells expressed desmin,GATA4, cTnI and connexin-43 in 5,10 μmol/L 5-aza groups, but no cardiac specific protein was found in neither 3μmol/L 5-aza group nor in the control group. The ratio of cTnI positively stained cells in 10 μmol/L group was higher than that in 5 μmol/L group (65.3 ± 4.7% vs 48.2 ± 5.4%, P < 0.05). Electron microscopy revealed that myofilaments were formed. The induced cells expressed cardiac-myosin heavy chain (MyHC) gene by reverse transcription-polymerase chain reaction (RT-PCR). Conclusions Theses findings suggest that hMSCs from adult bone marrow can be differentiated into cardiac-like muscle cells with 5-aza inducement in vitro and the differentiation is in line with the 5-aza concentration.

| 16 | Economic optimization of smart distribution networks considering real-time pricing显示文摘With the development of smart meters,a realtime pricing(RTP)demand response is becoming possible for households in distribution networks.The power flow can be bidirectional in distribution networks which become smarter with distributed generators(DGs).It is expensive to import electricity from the generation far from load centers because of the cost of power loss and network use,so that it is more economical to use electricity generated by local distributed generators.Therefore,in order to curtail operating costs of distribution networks,this paper proposes a model of economic optimization conducted by distribution network operators.The electricity purchasing costs for distribution network operators are minimized by optimizing electric power from transmission systems and local distributed generators.Further,based on price elasticity,the formulations of load demand considering RTP are proposed with economic optimization of distribution networks.The economic optimization problems are resolved by an interior point method.The case study shows that peak load demand can be reduced about 3.5%because the household RTP and electricity purchasing costs of distribution network operators can save 28.86£every hour. | Hong ZHANG Dongmei ZHAO Chenghong GU Furong LI Bo WANG | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，4： | 5 |
| 17 | Effects of substituent position on the interactions between PBDEs/PCBs and DOM显示文摘Dissolved organic matters (DOM) have important influence on the environmental behavior and fate of organic pollutants, therefore rationalization of interaction mechanisms between pollutants and DOM has become a hot topic in the field of environmental studies. In this paper, polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs), widely detected pollutants, were chosen as target compounds. The effects of substituent position on the interaction between PBDEs/PCBs and DOM were explored. Equilibrium dialysis technique combined with quantum chemistry and molecular docking calculations were employed to reveal the interaction mechanism from the view of charge distribution and molecular conformation. It is shown that non-ortho-substituted isomers have larger volumes and stronger hydrophobicity than those of ortho-substituted, therefore non-ortho-substituted isomers bind more favorably with DOM by hydrophobic partition. By calculating the atomic charge distribution of target chemicals and Leonardite humic acid (LHA) molecular model, π-πinteractions between the aromatic rings of target chemicals with LHA are proposed and further proved in molecular docking calculations. There were 10, 8, 6 docking conformations demonstrating π-πinteraction with LHA for CB-77, BDE-77 and BDE-47, respectively, but none was found for CB-47. By comparing the change of dihedral angle of the aromatic rings and energy barrier, non-ortho-substituted PBDEs/PCBs have larger dihedral angle adjustment space and flexibility, which results in stronger interaction and binding capability with DOM than ortho-substituted isomers. This paper shed some lights on the effect of substituent position on the environmental behaviors of PBDEs and PCBs. | NUERLA AiLiJiang QIAO XianLiang LI Jing ZHAO DongMei YANG XianHai XIE Qing CHEN JingWen | 2013 | Chinese Science Bulletin2013，58，8： | 4 |
