| 1 | Asian summer monsoon precipitation recorded by stalagmite oxygen isotopic composition in the western Loess Plateau during AD1875―2003 and its linkage with ocean-atmosphere system显示文摘Based on 5 high-precision 230Th dates and 103 stable oxygen isotope ratios (δ18O) obtained from the top 16 mm of a stalagmite collected from Wanxiang Cave,Wudu,Gansu,variation of monsoonal precipita-tion in the modern Asian Monsoon (AM) marginal zone over the past 100 years was reconstructed. Comparison of the speleothem δ18O record with instrumental precipitation data at Wudu in the past 50 years indicates a high parallelism between the two curves,suggesting that the speleothem δ18O is a good proxy for the AM strength and associated precipitation,controlled by 'amount effect' of the pre-cipitation. Variation of the monsoonal precipitation during the past 100 years can be divided into three stages,increasing from AD 1875 to 1900,then decreasing from AD 1901 to 1946,and increasing again thereafter. This variation is quite similar to that of the Drought/Flooding index archived from Chinese historical documents. This speleothem-derived AM record shows a close association with the Pacific Decadal Oscillation (PDO) between AD 1875 and 1977,with higher monsoonal precipitation corre-sponding to cold PDO phase and vice versa at decadal timescale. The monsoonal precipitation varia-tion is out of phase with the PDO after AD 1977,probably resulting from the decadal climate jump in the north Pacific occurring at around AD 1976/77. These results demonstrate a strong linkage between the AM and associated precipitation and the Pacific Ocean via ocean/atmosphere interaction. This rela-tionship will aid to forecast future hydrological cycle for the AM monsoon region,and to improve forecasting potential of climatic model with observation data from cave. | LIU JingHua ZHANG PingZhong CHENG Hai CHEN FaHu YANG XunLin ZHANG DeZhong ZHOU Jing JIA JiHong AN ChunLei SANG WenCui Kathleen R.

| 2 | Transcriptome analysis reveals long noncoding RNAs involved in fiber development in cotton (Gossypium arboreum)显示文摘Long noncoding RNAs(lnc RNAs)play important roles in various biological regulatory processes in yeast,mammals,and plants.However,no systematic identification of lnc RNAs has been reported in Gossypium arboreum.In this study,the strand-specific RNA sequencing(ss RNA-seq)of samples from cotton fibers and leaves was performed,and lnc RNAs involved in fiber initiation and elongation processes were systematically identified and analyzed.We identified 5,996 lnc RNAs,of which 3,510 and 2,486 can be classified as long intergenic noncoding RNAs(linc RNAs)and natural antisense transcripts(lnc NAT),respectively.Linc RNAs and lnc NATs are similar in many aspects,but have some differences in exon number,exon length,and transcript length.Expression analysis revealed that 51.9%of linc RNAs and 54.5%of lnc NATs transcripts were preferentially expressed at one stage of fiber development,and were significantly highly expressed than protein-coding transcripts(21.7%).During the fiber and rapid elongation stages,rapid and dynamic changes in lnc RNAs may contribute to fiber development in cotton.This work describes a set of lnc RNAs that are involved in fiber development.The characterization and expression analysis of lnc RNAs will facilitate future studies on their roles in fiber development in cotton. | Changsong Zou Qiaolian Wang Cairui Lu Wencui Yang Youping Zhang Hailiang Cheng Xiaoxu Feng Mtawa Andrew Prosper Guoli Song | 2016 | Science China(Life Sciences)2016,59,2: | 9 |
| 3 | Implications of stalagmite density for past climate change:An example from stalagmite growth during the last deglaciation from Wanxiang Cave,western Loess Plateau显示文摘The density of a stalagmite(WX42A)from Wanxiang Cave,Wudu County,Gansu Province,China,in the western margin of the Asian summer monsoon region,presents regular fluctuations in different deposition periods during the last deglaciation.Over long timescales,high-precision 230Th dating and high-resolution stalagmite density data indicate that the density-time series between 17644 a BP and 12758 a BP is quite similar to the stalagmite δ18O record which reflects Asian monsoon intensity.Strengthening/weakening(lighter/heavier stalagmite δ18O values)of the Asian monsoon is accompanied by increase/decrease in stalagmite density.Over short timescales,decrease in stalagmite density correlates to monsoon-retreat events such as the Inter-AllerФd Cold Period(IACP),Older Dryas(OD)and Inter-BФlling Cold Period(IBCP).Generally,this kind of decrease in stalagmite density reflects precipitation decrease with weakening of the Asian monsoon,which in turn slows cave dripwater rate and decreases crystal nuclei,leading to enlargement of calcite crystals,weakened biological activity and decreased soil pCO2 which increases the abundance of impure detrital materials in stalagmites.However,during the period of large amplitude reduction of precipitation and biological activity which resulted from extreme monsoon-retreat events,temperature variation would dominate fluctuation of stalagmite density.For example,stalagmite density increased suddenly when temperature dropped suddenly in the north Atlantic during Heinrich event 1(H-1).This may be caused by low seepage water temperature,more dissolved calcium carbonate,compact regular crystals forming under higher supersaturation,leading to the stalagmite increased density.Stalagmite density fluctuation sensitively recorded stalagmite growth history and environment,demonstrating that stalagmite density can be used as a proxy for paleoclimatic research. | ZHANG DeZhong ZHANG PingZhong SANG WenCui CHENG Hai WU XiuPing YUAN Ye BAI YiJun WANG JiangLin JIA JiHong | 2010 | Chinese Science Bulletin2010,55,34: | 7 |
| 4 | Development of systems for detection,early warning,and control of pipeline leakage in drinking water distribution:A case study显示文摘Water leakage in drinking water distribution systems is a serious problem for many cities and a huge challenge for water utilities.An integrated system for the detection,early warning,and control of pipeline leakage has been developed and successfully used to manage the pipeline networks in selected areas of Beijing.A method based on the geographic information system has been proposed to quickly and automatically optimize the layout of the instruments which detect leaks.Methods are also proposed to estimate the probability of each pipe segment leaking (on the basis of historic leakage data),and to assist in locating the leakage points (based on leakage signals).The district metering area (DMA) strategy is used.Guidelines and a flowchart for establishing a DMA to manage the large-scale looped networks in Beijing are proposed.These different functions have been implemented into a central software system to simplify the day-to-day use of the system.In 2007 the system detected 102 non-obvious leakages (i.e.,14.2% of the total detected in Beijing) in the selected areas,which was estimated to save a total volume of 2,385,000 m 3 of water.These results indicate the feasibility,efficiency and wider applicability of this system. | Weifeng Li Wencui Ling Suoxiang Liu Jing Zhao Ruiping Liu Qiuwen Chen Zhimin Qiang Jiuhui Qu | 2011 | Journal of Environmental Sciences2011,23,11: | 6 |

| 7 | Controllable synthesis of high loading LiFePO_4/C nanocomposites using bimodal mesoporous carbon as support for high power Li-ion battery cathodes显示文摘Mesoporous LiFePO4/C composites containing 80 wt% of highly dispersed LiFePO4 nanoparticles(4-6 nm) were fabricated using bimodal mesoporous carbon(BMC) as continuous conductive networks. The unique pore structure of BMC not only promises good particle connectivity for LiFePO4, but also acts as a rigid nano-confinement support that controls the particle size. Furthermore, the capacities were investigated respectively based on the weight of LiFePO4 and the whole composite. When calculated based on the weight of the whole composite, it is 120 mAh·g-1at 0.1 C of the high loading electrode and 42 mAh·g-1at 10 C of the low loading electrode. The electrochemical performance shows that high LiFePO4 loading benefits large tap density and contributes to the energy storage at low rates, while the electrode with low content of LiFePO4 displays superior high rate performance, which can mainly be due to the small particle size, good dispersion and high utilization of the active material, thus leading to a fast ion and electron diffusion. | Fei Cheng Duo Li Anhui Lu Wencui Li | 2013 | Journal of Energy Chemistry2013,22,6: | 2 |
| 8 | Interleukin 1 beta-induced chloride currents are important in osteoarthritis onset:an in vitro study显示文摘Persistent hypotonic and inflammatory conditions in the joint cavity can lead to the loss of cartilage matrix and cell death,which are the important mechanisms of osteoarthritis(OA)onset.Previous studies have confirmed that the existence of a hypotonic environment is a red flag for inflammation,as hypotonic environment induces the opening of the chloride channel of the cell and promotes chloride ion efflux,which prompts the cell volume to increase.Chloride channels play an important role in the regulation of mineralization and chondrocyte death.Here,we reported that OA chondrocytes showed a significant increase of cell death rate and the imbalance of cartilage matrix catabolism.We found that the distribution of skeleton protein F-actin was disordered.In addition,the volume-sensitive chloride current of OA chondrocytes decreased significantly with the increase of the expression levels of inflammation-related proteins caspase-1,caspase-3,and NLRP3.Moreover,interleukin-1β(IL-1β)showed a potential to activate the chloride current of normal chondrocytes.These results indicate that IL-1β-induced chloride channel opening in chondrocytes may be closely related to the occurrence of OA.This chloride channel opening process may therefore be a potential target for the treatment of OA. | Zhiqin Deng Zicong Lin Qing Zhong Minqiang Lu Huankun Fang Jianquan Liu Li Duan Lixin Chen Liwei Wang Daping Wang Wencui Li | 2021 | Acta Biochimica et Biophysica Sinica2021,53,4: | 2 |
| 9 | Fabrication of functional hollow carbon spheres with large hollow interior as active colloidal catalysts显示文摘In this study,we have established a facile method to synthesize functional hollow carbon spheres with large hollow interior,which can act as active colloidal catalysts.The method includes the following steps:first,hollow polymer spheres with large hollow interior were prepared using sodium oleate as the hollow core generator,and 2,4-dihydroxybenzoic acid and hexamethylene tetramine(HMT) as the polymer precursors under hydrothermal conditions;Fe 3+ or Ag + cations were then introduced into the as-prepared hollow polymer spheres through the carboxyl groups;finally,the hollow polymer spheres can be pseudomorphically converted to hollow carbon spheres during pyrolysis process,meanwhile iron or silver nanoparticles can also be formed in the carbon shell simultaneously.The structures of the obtained functional hollow carbon spheres were characterized by TEM,XRD,and TG.As an example,Ag-doped hollow carbon spheres were used as colloid catalysts which showed high catalytic activity in 4-nitrophenol reduction reaction. | Qiang Sun Guanghui Wang Wencui Li Xiangqian Zhang Anhui Lu | 2012 | Journal of Natural Gas Chemistry2012,21,3: | 2 |
