| 2 | A new classification of seepage control mechanisms in geotechnical engineering显示文摘Seepage flow through soils,rocks and geotechnical structures has a great influence on their stabilities and performances,and seepage control is a critical technological issue in engineering practices.The physical mechanisms associated with various engineering measures for seepage control are investigated from a new perspective within the framework of continuum mechanics;and an equation-based classification of seepage control mechanisms is proposed according to their roles in the mathematical models for seepage flow,including control mechanisms by coupled processes,initial states,boundary conditions and hydraulic properties.The effects of each mechanism on seepage control are illustrated with examples in hydroelectric engineering and radioactive waste disposal,and hence the reasonability of classification is demonstrated.Advice on performance assessment and optimization design of the seepage control systems in geotechnical engineering is provided,and the suggested procedure would serve as a useful guidance for cost-effective control of seepage flow in various engineering practices. | Yifeng Chen Ran Hu Chuangbing Zhou Dianqing Li Guan Rong Qinghui Jiang | 2010 | Journal of Rock Mechanics and Geotechnical Engineering2010，2，3： | 10 |
| 3 | Uncertainty analysis of correlated non-normal geotechnical parameters using Gaussian copula显示文摘Determining the joint probability distribution of correlated non-normal geotechnical parameters based on incomplete statistical data is a challenging problem.This paper proposes a Gaussian copula-based method for modelling the joint probability distribution of bivariate uncertain data.First,the concepts of Pearson and Kendall correlation coefficients are presented,and the copula theory is briefly introduced.Thereafter,a Pearson method and a Kendall method are developed to determine the copula parameter underlying Gaussian copula.Second,these two methods are compared in computational efficiency,applicability,and capability of fitting data.Finally,four load-test datasets of load-displacement curves of piles are used to illustrate the proposed method.The results indicate that the proposed Gaussian copula-based method can not only characterize the correlation between geotechnical parameters,but also construct the joint probability distribution function of correlated non-normal geotechnical parameters in a more general way.It can serve as a general tool to construct the joint probability distribution of correlated geotechnical parameters based on incomplete data.The Gaussian copula using the Kendall method is superior to that using the Pearson method,which should be recommended for modelling and simulating the joint probability distribution of correlated geotechnical parameters.There exists a strong negative correlation between the two parameters underlying load-displacement curves.Neglecting such correlation will not capture the scatter in the measured load-displacement curves.These results substantially extend the application of the copula theory to multivariate simulation in geotechnical engineering. | LI DianQing TANG XiaoSong ZHOU ChuangBing PHOON Kok-Kwang | 2012 | Science China(Technological Sciences)2012，55，11： | 10 |
| 4 | In vivo self-assembled small RNAs as a new generation of RNAi therapeutics显示文摘RNAi therapy has undergone two stages of development,direct injection of synthetic siRNAs and delivery with artificial vehicles or conjugated ligands;both have not solved the problem of efficient in vivo siRNA delivery.Here,we present a proof-of-principle strategy that reprogrammes host liver with genetic circuits to direct the synthesis and self-assembly of siRNAs into secretory exosomes and facilitate the in vivo delivery of siRNAs through circulating exosomes.By combination of different genetic circuit modules,in vivo assembled siRNAs are systematically distributed to multiple tissues or targeted to specific tissues(e.g.,brain),inducing potent target gene silencing in these tissues.The therapeutic value of our strategy is demonstrated by programmed silencing of critical targets associated with various diseases,including EGFR/KRAS in lung cancer,EGFR/TNC in glioblastoma and PTP1B in obesity.Overall,our strategy represents a next generation RNAi therapeutics,which makes RNAi therapy feasible. | Zheng Fu Xiang Zhang Xinyan Zhou Uzair Ur-Rehman Mengchao Yu Hongwei Liang Hongyuan Guo Xu Guo Yan Kong Yuanyuan Su Yangyang Ye Xiuting Hu Wei Cheng Jinrong Wu Yanbo Wang Yayun Gu Sheng-feng Lu Dianqing Wu Ke Zen Jing Li Chao Yan Chen-Yu Zhang Xi Chen | 2021 | Cell Research2021，31，6： | 10 |
| 5 | Endothelial CDS2 deficiency causes VEGFA-mediated vascular regression and tumor inhibition显示文摘The response of endothelial cells to signaling stimulation is critical for vascular morphogenesis,homeostasis and function.Vascular endothelial growth factor-a(VEGFA)has been commonly recognized as a pro-angiogenic factor in vertebrate developmental,physiological and pathological conditions for decades.Here we report a novel finding that genetic ablation of CDP-diacylglycerol synthetase-2(CDS2),a metabolic enzyme that controls phosphoinositide recycling,switches the output of VEGFA signaling from promoting angiogenesis to unexpectedly inducing vessel regression.Live imaging analysis uncovered the presence of reverse migration of the angiogenic endothelium in cds2 mutant zebrafish upon VEGFA stimulation,and endothelium regression also occurred in postnatal retina and implanted tumor models in mice.In tumor models,CDS2 deficiency enhanced the level of tumorsecreted VEGFA,which in-turn trapped tumors into a VEGFA-induced vessel regression situation,leading to suppression of tumor growth.Mechanistically,VEGFA stimulation reduced phosphatidylinositol(4,5)-bisphosphate(PIP2)availability in the absence of CDS2-controlled-phosphoinositide metabolism,subsequently causing phosphatidylinositol(3,4,5)-triphosphate(PIP3)deficiency and F0X01 activation to trigger regression of CDS2-null endothelium.Thus,our data indicate that the effect of VEGFA on vasculature is context-dependent and can be converted from angiogenesis to vascular regression. | Wencao Zhao Le Cao Hanru Ying Wenjuan Zhang Dantong Li Xiaolong Ziiu Wenzhi Xue Shuang Wu Mengye Cao Cong Fu Haonan Qi Yimei Hao Yun-Chi Tang Jun Qin Tao PZhong Xiaoxi Lin Luyang Yu Xuri Li Lin Li Dianqing Wu Weijun Pan | 2019 | Cell Research2019，29，11： | 9 |
| 6 | Impact of RMB Appreciation on Trade and Labor Markets of China and the USA:A Multi-country Comparative General Equilibrium Model显示文摘自从最近的经济危机,中国的汇率的 undervaluation 是在全球政策混合上的争论的一个焦点。用一张非竞争的 inputoutput 桌子,我们建立一个比较静电干扰的一般平衡模型在 SinoUS 贸易和劳动市场上模仿真实汇率变化的影响。中国和劳动的贸易剩余上的一个 10 百分比 RMB 再估价的影响 USA 出售的模拟表演比更谦虚通常被察觉,并且在中国的非处理的工业的产量上的否定影响在处理工业上是比那更重要的。SinoUS 贸易不平衡将继续败坏,中国的非处理的贸易剩余愿望衰落和处理贸易将增加,与是小的联合效果。为 USA,从中国进口的劳动密集型的商品将变到不同亚洲国家而不是转回到 US 市场。模拟结果显示汉语和美国劳动市场上的一个 RMB 再估价的影响将是有限的。 | Xin Li Dianqing Xu | 2011 | China & World Economy2011，19，2： | 7 |
| 7 | Synthesis of hexaaluminate catalysts for methane combustion by reverse microemulsion medium显示文摘The aim of this study is to synthesize the catalysts of Fe-and Mn-substituted hexaaluminate by reverse microemulsion medium for methane catalytic combustion application.Pseudo-ternary phase diagrams in quaternary microemulsion systems of cetyltrimethylammonium bromide(CTAB),n-butanol,n-octane,and water [or Al(NO3)3 solution] were presented.The effects of the alcohol chain length,ratio of sur-factant to cosurfactant,and salt concentration on the formation and stability of microemulsion systems were studied.The phase behavior of microemulsion systems was confirmed through the varying of the conductivity with the water content.The performance and structure of the catalysts,La(Mnx/Fex)Al12-x-O19-δ synthesized with the optimal parameter in the phase diagrams of microemulsions systems were characterized by BET,TG-DTA,and XRD.The micro fix-bed reactor was used to measure the catalytic activities of catalysts to methane combustion.The results showed that this synthesis method could yield non-agglomerated and highly dispersed precursors that would undergo crystallization at the lower temperature of 950℃.When temperature was raised up to 1050℃,the complete crystalline La-hexaaluminate was shaped.The hexaaluminate substituted with Fe had high-catalytic activity and stability at high temperature,while the Mn-substituted had higher catalytic activity at lower temperature.When the cooperation of Fe and Mn occurred,i.e.,LaFeMnAl10O19-δ exhibited a high surface area and catalytic activity to CH4 combustion,the CH4 light-off temperature was only 475℃ and the complete combustion temperature was 660℃.This was attributed to the synergistic effect between Fe and Mn. | BAI ShouLi WANG LiangShi SHI BingJie YANG PengCheng CUI MeiSheng LONG ZhiQi LI DianQing CHEN AiFan | 2009 | Science China Chemistry2009，52，1： | 6 |
| 8 | Template-free synthesis of three-dimensional NiFe-LDH hollow microsphere with enhanced OER performance in alkaline media显示文摘Flower-like hierarchical three-dimensional Ni Fe layered double hydroxides hollow microspheres(3D NiFe-LDH HMS),as one kind of novel non-noble metal electrocatalysts,have been fabricated in a templatefree route for water oxidation.Both of the concentration of ammonium fluoride and the reaction time are adjusted to obtain a series of Ni Fe-LDH microspheres,with different internal structures from massive to hollow generated during the hydrothermal treatment,which improve the electrocatalytic activity of the Ni Fe-LDH catalysts towards the evolution reaction of oxygen.The optimized Ni Fe-LDH-0.4M HMS show the excellent OER performance in alkaline electrolyte withη=290 mV@10 mA cm^-2,and a Tafel slope of 51 mV dec-1,which outperforms the benchmark RuO2 catalyst.The possible reason is attributed to the more exposure of active sites,and fast ion transport resulting from the hierarchical hollow structure. | Haihong Zhong Tongyuan Liu Shuwei Zhang Dianqing Li Pinggui Tang Nicolas Alonso-Vante Yongjun Feng | 2019 | Journal of Energy Chemistry2019，28，6： | 5 |
| 9 | Synthesis of Mg-Al-carbonate layered double hydroxide by an atom-economic reaction显示文摘A clean method for preparing layered double hydroxides (LDHs) has been developed, featured by using the hydroxides of two different metals as starting materials by atom-economic reactions. The reactions were carried out under hydrothermal conditions in either a high pressure autoclave or a microwave digester. The compositions, structural parameters and thermal behavior of the resulting LDHs are very similar to those of materials produced by using the separate nucleation and aging steps (SNAS) method. The major advantage of the new method is that no by-product is produced, so that filtration and washing processes are unnecessary. The consequent reduction in water consumption is beneficial to the environment. | Xiangyu Xu Dianqing Li Jiaqing Song Yanjun Lin Zhi Lv Min Wei Xue Duan | 2010 | Particuology2010，8，3： | 4 |
| 10 | Preparation and characterization of spherical mesoporous ZrO_(2)-Al_(2)O_(3) composites with high thermal stability显示文摘Spherical mesoporous ZrO_(2)-Al_(2)O_(3) composites containing different zirconia content have been synthesized by an oil-column sol-gel method.A mixed alumina-zirconia hydrosol and hexamethylenetetramine solution were mixed together and added dropwise into a hot oil column.Due to the surface tension,spherical gel particles were formed in the oil column.The spherical gel particles were then aged and washed by deionized water and dried at 120 ℃ for 12 h and then calcined at 600 ℃ for 8 h,960 ℃ for 8 h or 1200 ℃ for 12 h.X-ray diffraction and nitrogen adsorption-desorption measurements indicated that the presence of zirconia prevents the sintering of alumina and the obtained ZrO_(2)-Al_(2)O_(3) composites have much larger surface areas than pure alumina.Temperature-programmed desorption of ammonia results illustrated that the addition of zirconia leads to an increase in the number of strong acid sites and the total number of acid sites compared with pure alumina.Thus,the spherical mesoporous ZrO_(2)-Al_(2)O_(3) composites prepared in this way were shown to be suitable for high temperature catalytic processes as a catalyst support. | LI Yang FENG JunTing LI DianQing | 2011 | Science China Chemistry2011，54，7： | 2 |

| 12 | Re-estimation of China's Degree of Trade Dependence and External Imbalance: Value-added Statistics in the Global Production Chain显示文摘GDP与外贸数据的扭曲夸大了中国外贸依存度及外贸失衡度。GDP的扭曲主要来自汇率法与购买力平价法估算的差异;贸易数据扭曲包括:关境统计的重复计算以及由产权问题导致的国际贸易物流与资金流的不一致。对2007年我国实际外贸依存度及其失衡度的重估显示:2007年中国的外贸依存度从官方统计的68.02%下调为31.59%,外贸失衡度也从官方统计的10.13%下调为2.11%。所谓'中国操纵汇率'的指责是毫无根据的。 | Li Xin Xu Dianqing | 2013 | Social Sciences in China2013，34，4： | 2 |
