2Quantitative determination of AI-2 quorum-sensing signal of bacteria using high performance liquid chromatography–tandem mass spectrometry显示文摘Autoinducer 2(AI-2), an important bioactive by-product of the Lux S-catalyzed S-ribosylhomocysteine cleavage reaction in the activated-methyl-cycle, has been suggested to serve as a universal intra- and inter-species signaling molecule. The development of reliable and sensitive methods for quantitative determination of AI-2 is highly desired.However, the chemical properties of AI-2 cause difficulty in its quantitative analysis.Herein, we report a high performance liquid chromatography-tandem mass spectrometric method that enables reproducible and sensitive measurement of AI-2 concentrations in complex matrixes. 4,5-Dimethylbenzene-1,2-diamine(DMBDM), an easy-to-obtain commercial reagent, was used for the derivatization treatment. The assay was linear in the concentration range of 1.0–1000 ng/m L(R^2= 0.999) and had a lower limit of quantification of0.58 ng/m L. The method exhibited several advantages, e.g., high selectivity, wide linear response range, and good sensitivity. Furthermore, the effectiveness of the method was further validated through measuring AI-2 concentrations in the cell-free culture supernatant from Escherichia coli wild type.Fang Xu Xiangning Song Peijie Cai Guoping Sheng Hanqing Yu 2017Journal of Environmental Sciences2017,29,2:8

4ViWoSG:A distributed scene graph of ultra-massive distributed virtual environments显示文摘An ultra-massive distributed virtual environment generally consists of ultra-massive terrain data and a large quantity of objects and their attribute data, such as 2D/3D geometric models, audio/video, images, vectors, characteristics, etc. In this paper, we propose a novel method for constructing distributed scene graphs with high extensibility. This method can support high concurrent interaction of clients and implement various tasks such as editing, querying, accessing and motion controlling. Some application experiments are performed to demonstrate its efficiency and soundness.WANG GuoPing, LI Sheng, WANG ShaoRong, LU Bin & LI WenHang Key Lab of Machine Perception and Intelligent, MOE Department of Computer Science, Peking University, Beijing 100871, China 2009Science in China(Series F)2009,52,3:3
5Experimentai Research on Saturated-Gain for Soft X-Ray Laser from Neon-Like Germanium Plasma显示文摘AmpliHcation of spontaneous emissions at 19.6,23.2 and 23.6 nm have been observed by a “ultiple-Target Series Coupling”design in Ge plasma,.The combined length for four targets is up to 56mm.The gain length product(GL)of small signal is up to 18 for both lines at 23.2 and 23.6 nmt and the effective GL is 16.4 and 15.7 for these two lines respectively.This two lines are obviously tending to saturation.The divergence of x-ray laser beam is about 4 mrad.WANG Shiji GU Yuan ZHOU GuanUn NI Yuanlong YU Songyu FU Sizu MAO Chusheng TAO Zucong CHEN Wannian LIN Zunqi FAN Dianyuan ZHANG Guoping SHENG Jiatian YANG Minglun ZHANG Tanxin SHAO Yunfeng PENG Huimin HE Xiantu YU Min 1991Chinese Physics Letters1991,8,12:3
6Degradation and mineralization of 2-chlorophenol in a single-stage anaerobic fixed-bed bioreactor显示文摘Chlorophenols(CPs) have drawn great attention due to their high toxicity and ubiquitous presence in the environment. However,the practical application of anaerobic biodegradation to remove CPs is limited by low degradation rate and incomplete mineralization. This work aims to apply a single-stage anaerobic fixed-bed bioreactor(An FBR) for complete anaerobic dechlorination and mineralization of CPs. Results showed that 2-CP removal efficiency of 99.4%, chemical oxygen demand(COD)removal efficiency of 93.0%, and methane yield of 0.22 L-CH4/g-COD could be obtained for a wide range of 2-CP loading rates(3.6–18.2 mmol L–1 d–1). Nearly complete anaerobic mineralization of 2-CP was achieved even in the absence of co-substrates,thereby greatly reducing the operation cost. This may be partly related to the attached-growth microorganisms in An FBR,allowing a higher biomass concentration and longer biomass retention time for enhanced 2-CP removal. Moreover, 16 S r RNA gene sequence analysis suggests that the An FBR harbored the potential dechlorinators(e.g., Anaeromyxobacter), phenoldegrading microbes(e.g., Comamonas and Syntrophobacter), and methanogens(e.g., Methanobacterium and Methanosaeta)after acclimation, which could cooperate effectively for 2-CP dechlorination and mineralization. Based on the identified intermediates, the possible mineralization pathway of 2-CP was proposed. These findings should be valuable to facilitate the engineering applications of An FBRs for removing CPs from wastewater.GENG YiKun LI ZhengHao YUAN Li PAN XinRong SHENG GuoPing 2020Science China(Technological Sciences)2020,63,1:2
