| 1 | Bearing characteristics of coal pillars based on modified limit equilibrium theory显示文摘There are two states for the coal-mass on the goaf-side which is in stress equilibrium: the state of limit equilibrium(the bearing stress in the coal-mass equals its ultimate bearing stress) and the state of nonultimate equilibrium(the bearing stress in the coal-mass is less than its ultimate bearing stress). To analyze the bearing characteristics of a coal pillar in the state of limit equilibrium and guide the design of pillar width, we established a mechanical analytical model of the non-ultimate equilibrium zone in the coal-mass on the goaf-side combined with the limit equilibrium theory as well as adopting the methods of theory analysis and mechanical analysis based on the assumption of a state of non-ultimate equilibrium. The width correction coefficient of the limit equilibrium zone has been given. The influence of mining depth, stress concentration coefficient of the surrounding rock, the non-limit strength of the coal-mass and stability of the coal rock interface has been studied. On this basis, we have confirmed that when the width of a longwall mining face roadway protection coal pillar is between 11.6 m and 13.16 m in No. 4 coal seam of Xinrui coal mine in Lvliang in Shanxi province the elastic core region in the coal pillar can be assured and the roadway will be located in the area of lower stress which is outside the peak stress. So the revised width of the limit equilibrium zone is more practical. | Wang Xiangyu Bai Jianbiao Wang Ruofan Sheng Wenlong | 2015 | International Journal of Mining Science and Technology2015，25，6： | 6 |
| 2 | Methanogenic community dynamics in anaerobic co-digestion of fruit and vegetable waste and food waste显示文摘A lab-scale continuously-stirred tank reactor (CSTR), used for anaerobic co-digestion of fruit and vegetable waste (FVW) and food waste (FW) at different mixture ratios, was operated for 178 days at the organic loading rate of 3 kg VS (volatile solids)/(m3·day). The dynamics of the Archaeal community and the correlations between environmental variables and methanogenic community structure were analyzed by polymerase chain reactions-denaturing gradient gel electrophoresis (PCR-DGGE) and redundancy analysis (RDA), respectively. PCR-DGGE results demonstrated that the mixture ratio of FVW to FW altered the community composition of Archaea. As the FVW/FW ratio increased, Methanoculleus, Methanosaeta and Methanosarcina became the predominant methanogens in the community. Redundancy analysis results indicated that the shift of the methanogenic community was significantly correlated with the composition of acidogenic products and methane production yield. Different mixture ratios of substrates led to different compositions of intermediate metabolites, which may affect the methanogenic community. These results suggested that the analysis of microbial communities could be used to diagnose anaerobic processes. | Jia Lin Jiane Zuo Ruofan Ji Xiaojie Chen Fenglin Liu Kaijun Wang Yunfeng Yang | 2012 | Journal of Environmental Sciences2012，24，7： | 4 |

| 5 | High-throughput site-specific N-glycoproteomics reveals glyco-signatures for liver disease diagnosis显示文摘The glycoproteome has emerged as a prominent target for screening biomarkers,as altered glycosylation is a hallmark of cancer cells.In this work,we incorporated tandem mass tag labeling into quantitative glycoproteomics by developing a chemical labeling-assisted complementary dissociation method for the multiplexed analysis of intact N-glycopeptides.Benefiting from the complementary nature of two different mass spectrometry dissociation methods for identification and multiplex labeling for quantification of intact N-glycopeptides,we conducted the most comprehensive site-specific and subclass-specific N-glycosylation profiling of human serum immunoglobulin G(IgG)to date.By analysing the serum of 90 human patients with varying severities of liver diseases,as well as healthy controls,we identified that the combination of IgG1-H3N5F1 and IgG4-H4N3 can be used for distinguishing between different stages of liver diseases.Finally,we used targeted parallel reaction monitoring to successfully validate the expression changes of glycosylation in liver diseases in a different sample cohort that included 45 serum samples. | Zhenyu Sun Bin Fu Guoli Wang Lei Zhang Ruofan Xu Ying Zhang Haojie Lu | 2023 | National Science Review2023，10，1： | 1 |
| 6 | Influence of abnormal stress under a residual bearing coal pillar on the stability of a mine entry显示文摘Mine entries close to residual bearing coal pillars(RBCPs) will suffer large deformation that may cause rock burst. To better understand the deformation mechanism and develop safe and practical guidelines for entry design, most studies focus on the absolute size of the stress field in and around the pillar. In this paper, we present a new approach to analyze the abnormal stress field close to a RBCP that uses the stress concentration coefficient(SCC), stress gradient(SG), and coefficient of lateral pressure(CLP) to describe the stress state induced by the RBCP. Based on elastic theory and a mathematical model for the abutment stress in the RBCP, an analytical solution for the abnormal stress in the strata below the RBCP was derived and the characteristics of the abnormal stress for a case study of a coal mine in China were analyzed. The results show that the abnormal stress field around the pillar is characterized by four distinct zones: a zone of high SCC, high SG, and CLP less than 1, a zone of high SCC, low SG, and CLP less than 1, a zone of low SCC, SG close to 0, and CLP greater than 1, and a zone of SCC close to 1, SC close to 0, and CLP close to 1. Based on this zoning pattern, a numerical model was established to study the combined effects of the abnormal stress on the stability of the entry. The most stable zone was determined based on a model of the Xinrui coal mine and verified by field measurements at the mine. Our conclusions can be used as guidelines for designing safe entry layouts in similar geological and mining settings. | Kang Jizhong Shen Wenlong Bai Jianbiao Yan Shuai Wang Xiangyu Li Wenfeng Wang Ruofan | 2017 | International Journal of Mining Science and Technology2017，27，6： | 1 |
| 7 | Long and Covalently Conjugated Branched DNA Structures for in Situ Gelation in Vivo显示文摘DNA nanotechnology has been widely employed for biomedical applications.However,most DNA nanomaterials rely on noncovalent complementary base pairing of short single-stranded DNA oligonucleotides.Herein,we describe a general strategy to construct a long and covalently conjugated branched DNA structure for fast and in situ gelation in vivo.In our design,a short and covalently conjugated branched DNA structure can normally be employed as the DNA primer in the terminal deoxynucleotidyl transferase-dependent enzymatic polymerization system.After enzymatic extension,the DNA aptamer-modified branched DNA structures with the sequences of poly T or poly A can immediately coassemble for in situ encapsulation of the target protein and tumor cell.The fast and in situ gelation system can function in a murine model of local tumor recurrence for targeting residual tumor cells to achieve long-term drug release for efficient tumor inhibition in vivo.This rationally developed DNA self-assembly strategy provides a new avenue for the development of multifunctional DNA nanomaterials. | Xuehe Lu Hong Wang Ruofan Chen Tiantian Wu Xiaohui Wu Yingxu Shang Yuang Wang Wantao Tang Dongsheng Liu Jianbing Liu Baoquan Ding | 2023 | CCS Chemistry2023，5，9： | 0 |
