1A Pricing Model for Big Personal Data显示文摘Big Personal Data is growing explosively. Consequently, an increasing number of internet users are drowning in a sea of data. Big Personal Data has enormous commercial value; it is a new kind of data asset. An urgent problem has thus arisen in the data market: How to price Big Personal Data fairly and reasonably. This paper proposes a pricing model for Big Personal Data based on tuple granularity, with the help of comparative analysis of existing data pricing models and strategies. This model is put forward to implement positive rating and reverse pricing for Big Personal Data by investigating data attributes that affect data value, and analyzing how the value of data tuples varies with information entropy, weight value, data reference index, cost, and other factors. The model can be adjusted dynamically according to these parameters. With increases in data scale, reductions in its cost,and improvements in its quality, Big Personal Data users can thereby obtain greater benefits.Yuncheng Shen Bing Guo Yan Shen Xuliang Duan Xiangqian Dong Hong Zhang 2016Tsinghua Science and Technology2016,21,5:19
2Long-and short-chain AHLs affect AOA and AOB microbial community composition and ammonia oxidation rate in activated sludge显示文摘Quorum sensing(QS)regulation of the composition of ammonia-oxidising archaea(AOA)and ammonia-oxidising bacteria(AOB)communities and functions in wastewater treatment was investigated.Specifically,we explored the role of N-acyl-L-homoserine lactones(AHLs)in microbial community dynamics in activated sludge.On average,the specific ammoniaoxidising-rate increased from 1.6 to 2.8 mg NH_4^+-N/g MLSS/hr after treatment with long-chain AHLs for 16 days,and the addition of AHLs to sludge resulted in an increased number of AOA/AOB amoA genes.Significant differences were observed in the AOA communities of control and AHL-treated cultures,but not the AOB community.Furthermore,the dominant functional AOA strains of the Crenarchaeota altered their ecological niche in response to AHL addition.These results provide evidence that AHLs play an important role in mediating AOA/AOB microbial community parameters and demonstrate the potential for application of QS to the regulation of nitrogen compound metabolism in wastewater treatment.Jie Gao Yu Duan Ying Liu Xuliang Zhuang Yichen Liu Zhihui Bai Wenlin Ma Guoqiang Zhuang 2019Journal of Environmental Sciences2019,31,4:11
3Regulation of histone demethylase KDM6B by hypoxia-inducible factor-2α显示文摘离氨酸(K) 特定的 demethylase 6B (KDM6B ) 是 histone H3K27 demethylase,它明确地催化 H3 lysine-27 tri/dimethylation (H3K27me3/2 ) 的 demethylation。KDM6B 能由支持与 RNA 聚合酶 II 和相关延伸因素被联系的 transcriptional 延伸激活基因抄写。KDM6B 因此为基因表示的规定是重要的。以前的研究显示了象 KDM3A, KDM4B,和 KDM4C 那样的几 histone demethylases 被组织缺氧可诱导的因素(HIF ) 调整。但是, KDM6B 上的组织缺氧的效果充分没被理解。在这研究,我们发现 KDM6B mRNA 和蛋白质的表示层次在组织缺氧下面是平常地起来调整的(1% O 2) 或模仿组织缺氧(desferrioxamine mesylate 或 CoCl 2 处理)(P < 0.05 ) 。RNAi 的结果证明 KDM6B 的起来规定依赖于 HIF-2,然而并非在 HIF-1 上。染色质 immunoprecipitation 试金的结果显示在 KDM6B 倡导者(4041 ~ 4037 ) 有一个组织缺氧反应元素。Co-IP 试金的结果显示 KDM6B 能与 HIF-2 或 HIF-1 形成建筑群。击倒的实验暗示 KDM6B 是为 HIF-2 目标基因的一个潜在的管理者。这些数据证明 KDM6B 是 HIF-2 调整的新组织缺氧反应基因。我们的结果也证明 KDM6B 是 HIF- 的潜在的激活剂,它为组织缺氧反应基因的激活是重要的。Xiaoqiang Guo Zha ntao Tian Xuliang Wang Shuhong Pan Weiren Huang Yongqing Shen Yaoting Gui Xianglin Duan Zhiming Cai 2015Acta Biochimica et Biophysica Sinica2015,47,2:5
4A model for predicting bubble rise velocity in a pulsed gas solid fluidized bed显示文摘Bed stability, and especially the bed density distribution, is affected by the behavior of bubbles in a gas solid fluidized bed. Bubble rise velocity in a pulsed gas-solid fluidized bed was studied using photographic and computational fluid dynamics methods. The variation in bubble rise velocity was investigated as a function of the periodic pulsed air flow. A predictive model of bubble rise velocity was derived: ub=ψ(Ut+Up-Umf)+kp(gdb)(1/2). The software of Origin was used to fit the empirical coefficients to give ψ = 0.4807 and kp = 0.1305. Experimental verification of the simulations shows that the regular change in bubble rise velocity is accurately described by the model. The correlation coefficient was 0.9905 for the simulations and 0.9706 for the experiments.Dong Liang Zhao Yuemin Luo Zhenfu Duan Chenlong Wang Yingwei Yang Xuliang Zhang Bo 2013International Journal of Mining Science and Technology2013,23,2:4
5Progress in developments of dry coal beneficiation显示文摘China’s energy supply heavily relies on coal and China’s coal resource and water resource has a reverse distribution.The problem of water shortages restricts the applications of wet coal beneficiation technologies in drought regions.The present situation highlights the significance and urgency of developing dry beneficiation technologies of coal.Besides,other countries that produce large amounts of coal also encounter serious problem of lack of water for coal beneficiation,such as American,Australia,Canada,South Africa,Turkey and India.Thus,dry coal beneficiation becomes the research hot-points in the field of coal cleaning worldwide in recent years.This paper systematically reviewed the promising research efforts on dry coal beneficiation reported in literature in last 5 years and discussed the progress in developments of dry coal beneficiation worldwide.Finally,we also elaborated the prospects and the challenges of the development of dry coal beneficiation.Yuemin Zhao Xuliang Yang Zhenfu Luo Chenlong Duan Shulei Song 2014International Journal of Coal Science & Technology2014,1,1:3

7Influence of bubbles on the segregated stability of fine coal in a vibrated dense medium gas-solid fluidized bed显示文摘In this paper,the variation of bubble size and number in the separation process of vibrated fluidized bed as well as the influence of bubble movement on the axial distribution of fine coal in different positions of the bed were studied.The result revealed that the size and number of bubbles is correlated with the fine coal separation effect in the separation process.When the bed is in a uniform and stable fluidized state,the size of bubbles in the separation process was in the range of 1-2.5 cm and the number of bubbles was reduced by nearly 50%,which is helpful to promote the stratification and segregation of fine coal.Thereby,after separation,the ash content of refined coal products of anthracite and 1/3 coking coal was reduced to 12.1% and 23.7% respectively,and the content of refined coal was up to 42.5% and 68.5% respectively,which show that the vibrated fluidized bed has a good separation performance,and can separate efficiently the coal of size−6+1 mm.Enhui Zhou Yadong Zhang Yuemin Zhao Qingqing Tian Zengqiang Chen Guannan lv Xuliang Yang Liang Dong Chenlong Duan 2021Particuology2021,19,5:1

10A hierarchical salt-rejection strategy for sustainable and high-efficiency solar-driven desalination显示文摘Solar steam generation(SSG)is widely regarded as one of the most sustainable technologies for seawater desalination.However,salt fouling severely compromises the evaporation performance and lifetime of evaporators,limiting their practical applications.Herein,we propose a hierarchical salt-rejection(HSR)strategy to prevent salt precipitation during long-term evaporation while maintaining a rapid evaporation rate,even in high-salinity brine.The salt diffusion process is segmented into three steps—insulation,branching diffusion,and arterial transport—that significantly enhance the salt-resistance properties of the evaporator.Moreover,the HSR strategy overcomes the tradeoff between salt resistance and evaporation rate.Consequently,a high evaporation rate of 2.84 kg m^(-2) h^(-1),stable evaporation for 7 days cyclic tests in 20 wt%NaCl solution,and continuous operation for 170 h in natural seawater under 1 sun illumination were achieved.Compared with control evaporators,the HSR evaporator exhibited a>54%enhancement in total water evaporation mass during 24 h continuous evaporation in 20 wt%salt water.Furthermore,a water collection device equipped with the HSR evaporator realized a high water purification rate(1.1 kg m^(-2) h^(-1)),highlighting its potential for agricultural applications.Zhengyi Mao Xuliang Chen Yingxian Chen Junda Shen Jianpan Huang Yuhan Chen Xiaoguang Duan Yicheng Han Kannie Wai Yan Chan Jian LU 2024Nano Materials Science2024,6,1:0
