1Energy dissipation of coal and rock during damage and failure process based on EMR显示文摘The physical and mechanical change processes of coal and rock are closely related to energy transformation,and the destruction and failure of coal and rock is an instability phenomena driven by energy change.However,the energy change of large-scale coal rock in the mine site is hardly calculated accurately,making it difficult to monitor coal-rock systematic failure and collapse from the perspective of energy.By the energy dissipation EMR monitoring system,we studied the damage and failure of coal and rock with bursting liability from the energy dissipation point using the geophysical method-EMR,and explored the energy dissipation characteristics during uniaxial compression and their main influencing factors.The results show that under displacement-control loading mode,there are 2 types of energy dissipation trends for both coal and rock with bursting liability.The type Ⅰ trend is a steady increase one during the whole process,therein,the energy dissipation of rock samples is accelerated at the peak load.The type Ⅱ trend energy is a W-shaped fluctuating one containing 6 stages.Under load-control loading mode,there is one energy dissipation trend of shock downward-steady rise.Besides that,rock samples also present a trend of 4 stages.The energy dissipation characteristics of coal and rockduring loading failure process can be used as effective criteria to assess whether they are in a stable or destructive stage.The factors influencing energy dissipation in the loading failure process of coal and rock mainly include strength,homogeneity,and energy input efficiency.Song Dazhao Wang Enyuan Li Zhonghui Liu Jie Xu Wenquan 2015International Journal of Mining Science and Technology2015,25,5:16
2Solar influenced late Holocene temperature changes on the northern Tibetan Plateau显示文摘Considerable efforts have been made to extend temperature records beyond the instrumental period through proxy reconstructions,in order to further understand the mechanisms of past climate variability.Yet,the global coverage of existing temperature records is still limited,especially for some key regions like the Tibetan Plateau and for earlier times including the Medieval Warm Period(MWP).Here we present decadally-resolved,alkenone-based,temperature records from two lakes on the northern Tibetan Plateau.Characterized by marked temperature variability,our records provide evidence that temperatures during the MWP were slightly higher than the modern period in this region.Further,our temperature reconstructions,within age uncertainty,can be well correlated with solar irradiance changes,suggesting a possible link between solar forcing and natural climate variability,at least on the northern Tibetan Plateau.HE YuXin LIU WeiGuo ZHAO Cheng WANG Zheng WANG HuanYe LIU Yi QIN XianYan HU QiHou AN ZhiSheng LIU ZhongHui 2013Chinese Science Bulletin2013,58,9:11
3Rational design of novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructures for all-solid-state asymmetric supercapacitors显示文摘Constructing graphene-based heterostructures with large interfacial area is an efficient approach to enhance the electrochemical performance of supercapacitors but remains great challenges in their synthesis.Herein,a novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructure(a-Fe_(2)O_(3)NDs/RGO)aerogel was facilely synthesized via excessive metal-ion-induced self-assembly and subsequent calcination route using Prussian blue/graphene oxide(PB/GO)composite aerogel as precursors.The deliberately designed a-Fe_(2)O_(3)NDs/RGO heterostructure offers a highly interconnected porous conductive network,large heterostructure interfacial area,and plenty of accessible active sites,greatly facilitating the electron transfer,electrolyte diffusion,and pseudocapacitive reactions.The obtained a-Fe_(2)O_(3)NDs/RGO aerogel could be used as flexible free-standing electrodes after mechanical compression,which exhibited a significantly enhanced specific capacitance of 347.4 F·g^(-1)at 1 A·g^(-1),extraordinary rate capability of 184 F·g^(-1)at 10 A·g^(-1),and decent cycling stability.With the as-prepared a-Fe_(2)O_(3)NDs/RGO as negative electrodes and the Co_(3)O_(4)NDs/RGO as positive electrodes,an all-solid-state asymmetric supercapacitor(a-Fe_(2)O_(3)NDs/RGO//Co_(3)O_(4)NDs/RGO asymmetric supercapacitor(ASC))was assembled,which delivered a high specific capacitance of 69.1 F·g^(-1)at 1 A·g^(-1)and an impressive energy density of 21.6 W·h·k·g^(-1)at 750 W·k·g^(-1),as well as good cycling stability with a capacity retention of 94.3%after 5,000 cycles.This work provides a promising avenue to design high-performance graphene-based composite electrodes and profound inspiration for developing advanced flexible energy-storage devices.Chenxiao Wu Zhifang Zhang Zhonghui Chen Zuimin Jiang Huiyu Li Haijing Cao Yongsheng Liu Yanyan Zhu Zebo Fang Xiangrong Yu 2021Nano Research2021,14,4:6
4Acoustic emission generated during the gas sorption-desorption process in coal显示文摘An experimental system for monitoring the acoustic signals generated in coal during gas sorption and/or desorption was designed and the acoustic signals were observed under different gas pressures. The experimental results show that signals generated by the coal during gas adsorption are attenuated over time. Also, the signals are not continuous but are impulsive. The intensity of the signals generated during gas desorption is far smaller than that observed during adsorption. The signal seen during desorption remains essentially stable. Cycles of sorption and desorption cause acoustic emission signals that exhibit a memory effect, which depends upon the maximum gas pressure the sample was exposed to in earlier cycles. Lower pressures in subsequent cycles, compared to the maximum adsorption pressure in previous cycles, cause both the energy and impulse frequency to be lower than previously. On the contrary, a gas adsorption pressure that exceeds the maximum pressure seen by the sample during earlier cycles causes both the energy and impulse frequency to be high.Ma Yankun Wang Enyuan Xiao Dong Li Zhonghui Liu Jie Gan Lijia 2012International Journal of Mining Science and Technology2012,22,3:5
5Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis.Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao 2021Cell Research2021,31,12:5

7地球倾角驱动的末次冰期期间南亚地区变暖显示文摘当前对晚第四纪以来轨道尺度上地球气候变化的认识,主要包括高纬驱动的以~10万年周期为主的冰期-间冰期循环和夏季风影响的以~2.3万年周期为主的低纬水文变化.但是,由于低纬陆地没有较为可靠的温度记录,使得对低纬陆地的长期气候变化仍然缺乏全面的理解.本文通过获取云南腾冲青海的一根湖泊沉积岩芯,分析了沉积物中的支链甘油二烷基甘油四醚酯(brGDGTs)和叶蜡氢同位素,分别重建了~9万年以来南亚地区的年平均温度和季风降水的变化序列.结果表明,夏季风降水与之前的研究一致,表现出明显的2.3万年周期,但是年均温度记录揭示了8.8~7.1万年和4.5~2.2万年存在两个暖期,温度变幅2~3℃,与该记录中的冰期-间冰期变幅接近.通过对比TraCE21ka瞬态模拟结果和相关气候驱动因子,发现这两个暖期很可能受当地的年均太阳轨道辐射影响;而低纬地区的年均太阳辐射由以~4.1万年周期为主的地球倾角变化控制,并与高纬地区的年均太阳轨道辐射呈反向关系.此外,该记录中的两个暖期与古人类活动的年代有较强的相关性,表明末次冰期内温度变化可能对亚洲地区古人类的生存有重要的影响.赵成 Eelco J.Rohling Zhengyu Liu 杨小强 张恩楼 程军 Zhonghui Liu 安芷生 羊向东 冯小平 孙晓双 张灿 闫天龙 隆浩 晏宏 Zicheng Yuk 刘卫国 于世永 沈吉 2021Science Bulletin2021,66,11:5
8Activin A maintains cerebral cortex neuronal survival and increases voltage-gated Na^+ neuronal current显示文摘Activin A,which was first described in 1986,has been shown to maintain hippocampal neuronal survival.Activin A increases intracellular free Ca2+ via L-type Ca2+ channels.Our previous study showed that activin A promotes neurite growth of dorsal root ganglia in embryonic chickens and inhibits nitric oxide secretion.The present study demonstrated for the first time that activin A could maintain cerebral cortex neuronal survival in vitro for a long period,and that activin A was shown to increase voltage-gated Na+ current(INa) in Neuro-2a cells,which was recorded by patch clamp technique.The present study revealed a novel mechanism for activin A,as well as the influence of activin A on neurons by regulating expressions of vasoactive intestine peptide and inducible nitric oxide synthase.Jingyan Ge Yinan Wang Haiyan Liu Fangfang Chen Xueling Cui Zhonghui Liu 2010Neural Regeneration Research2010,5,19:4
9Direct Effects of Activin A on the Activation of Mouse Macrophage RAW264.7 Cells显示文摘Macrophages play critical roles in innate immune and acquired immune via secreting pro-inflammatory mediators, phagocytosing microorganisms and presenting antigens. Activin A, a member of transforming growth factor β (TGF-β) superfamily, is produced by macrophages and microglia cells. In this study, we reported a direct effect of activin A as a pro-inflammatory factor on mouse macrophage cell line RAW264.7 cells. Our data revealed that activin A could not only increase IL-1β and IL-6 production from RAW264.7 cells, but also promote pinocytic and phagocytic activities of RAW264.7 cells. In addition, activin A obviously up-regulated MHC II expression on the surface of RAW264.7 cells, whereas did not influence MHC I expression. Activin A also enhanced CD80 expression, which is a marker of activated macrophages, but did not influence RAW264.7 cell proliferation. These data suggest that activin A may regulate primary macrophage-mediated innate and acquired immune response via promoting the activation of rest macrophages.Jingyan Ge Yinan Wang Ye Feng Haiyan Liu Xueling Cui Guixiang Tai Zhonghui Liu 2009Cellular & Molecular Immunology2009,6,2:4
10Sustainable and invisible anti-counterfeiting inks based on waterborne polyurethane and upconversion nanoparticles for leather products显示文摘Counterfeit leather products infringe the intellectual property rights of the business,cause enormous economic loss,and negatively influence the business enthusiasm for innovation.However,traditional anti-counterfeiting materials for leather products suffer from complicated fabrication procedures,photobleaching,and high volatile organic com-pound(VOC)emissions.Here,a sustainable and invisible anti-counterfeiting ink composed of waterborne polyure-thane and water-dispersible lanthanide-doped upconversion nanoparticles(UCNPs)featuring ease of preparation,high photostability,non-toxicity,low VOC emissions,and strong adhesion strength for leather products is designed and synthesized.After decorating on the surface of leather products,the obtained patterns are invisible under normal light conditions.Upon irradiation at 808 nm,the invisible patterns can be observed by naked eyes due to the visible light emitted by 808 nm excited UCNPs.Our approach described here opens a new pathway to realize the long-term,stable anti-counterfeiting function of leather products.Jun Xiang Jianxun Lin Zhonghui Wang Shenglin Zhou Zhenya Wang Qiang Yan Yidong Liu Haojun Fan 2021Journal of Leather Science and Engineering2021,3,1:4
11Cenozoic Environmental Changes in the Northern Qaidam Basin Inferred from n-alkane Records显示文摘Cenozoic climatic and environmental changes in the arid Asian interior, and their possible relations with global climatic changes and the Tibetan Plateau uplift, have been intensively investigated and debated over past decades. Here we present 40-Myr(million years)-long n-alkane records from a continuous Cenozoic sediment sequence in the Dahonggou Section, Qaidam Basin, northern Tibetan Plateau, to infer environmental changes in the northern basin. A set of n-alkane indexes, including ACL, CPI and Paq, vary substantially and consistently throughout the records, which are interpreted to reflect relative contributions from terrestrial vascular plants vs. aquatic macrophytes, and thus indicate depositional environments. ACL values vary between 21 and 30; CPI values range from 1.0 to 8.0; and Paq values change from <0.1 to 0.8 over the past 40-Myr. We have roughly identified two periods, at 25.8–21.0 Ma(million years ago) and 13.0–17.5 Ma, with higher ACL and CPI and lower Paq values indicating predominant lacustrine environments. Lower ACL and CPI values, together with higher Paq values, occurred at >25.8 Ma, 17.5–21.0 Ma, and <13.0 Ma, corresponding to alluvial fan/river deltaic deposits and shallow lacustrine settings, consistent with the observed features in sedimentological facies. The inferred Cenozoic environmental changes in the northern Qaidam Basin appear to correspond to global climatic changes.LIU Zhonghui ZHANG Kexin SUN Yuanyuan LIU Weiguo LIU Yusheng(Christopher) QUAN Cheng 2014Acta Geologica Sinica(English Edition)2014,88,5:4
12RESEARCH ON ADAPTIVE COMPRESSION CODING FOR NETWORK CODING IN WIRELESS SENSOR NETWORK显示文摘Based on the sequence entropy of Shannon information theory, we work on the network coding technology in Wireless Sensor Network (WSN). In this paper, we take into account the similarity of the transmission sequences at the network coding node in the multi-sources and multi-receivers network in order to compress the data redundancy. Theoretical analysis and computer simulation results show that this proposed scheme not only further improves the efficiency of network transmission and enhances the throughput of the network, but also reduces the energy consumption of sensor nodes and extends the network life cycle.Liu Ying Yang Zhen Mei Zhonghui Kong Yuanyuan 2012Journal of Electronics(China)2012,29,5:4
13Regularity and mechanism of coal resistivity response with different conductive characteristics in complete stress-strain process显示文摘The stress,strain as well as resistivity of coal during uniaxial compression process were tested based on self-built real-time testing system of loaded coal resistivity.Furthermore,the coal resistivity regularity and mechanism were analyzed at different stages of complete stress-strain process,which includes the two kinds of coal body with typical conductive characteristics.The results indicate that coal resistivity with different conductive characteristics has different change rules in complete stress-strain process.It is mainly represented at the densification and flexibility phases before dilatation occurs.The variation of resistivity can be divided into two kinds,named down and up.Dilatation of coal samples occurred between 66%σ_(max) and 87%σ_(max).Because of dilatation,coal resistivity involves sudden change.The overall representation is shifting from reducing into improving or from slow improving into accelerated improving.Thus,coal resistivity always shows an increasing tendency at the plastic stage.After peak stress,coal body enters into failure stage.The expanding and communicating of macro fracture causes further improvement of coal resistivity.The maximum value of resistivity rangeability named λ reached 3.49.Through making real-time monitoring on coal resistivity,variation rules of resistivity can be deemed as precursory information so as to reflect the dilatation and sudden change before coal body reaches buckling failure,which can provide a new technological means for forecasting the dynamic disaster of coal petrography.Chen Peng Wang Enyuan Chen Xuexi Liu Zhentang Li Zhonghui Shen Rongxi 2015International Journal of Mining Science and Technology2015,25,5:3
14FT5a interferes with the Dt1-AP1 feedback loop to control flowering time and shoot determinacy in soybean显示文摘Flowering time and stem growth habit determine inflorescence architecture in soybean, which in turn influences seed yield. Dt1, a homolog of Arabidopsis TERMINAL FLOWER 1(TFL1), is a major controller of stem growth habit, but its underlying molecular mechanisms remain unclear.Here, we demonstrate that Dt1 affects node number and plant height, as well as flowering time,in soybean under long-day conditions. The b ZIP transcription factor FDc1 physically interacts with Dt1, and the FDc1-Dt1 complex directly represses the expression of APETALA1(AP1). We propose that FT5 a inhibits Dt1 activity via a competitive interaction with FDc1 and directly upregulates AP1. Moreover, AP1 represses Dt1 expression by directly binding to the Dt1 promoter, suggesting that AP1 and Dt1 form a suppressive regulatory feedback loop to determine the fate of the shoot apical meristem. These findings provide novel insights into the roles of Dt1 and FT5 a in controlling the stem growth habit and flowering time in soybean, which determine the adaptability and grain yield of this important crop.Lin Yue Xiaoming Li Chao Fang Liyu Chen Hui Yang Jie Yang Zhonghui Chen Haiyang Nan Linnan Chen Yuhang Zhang Haiyang Li Xingliang Hou Zhicheng Dong James LWeller Jun Abe Baohui Liu Fanjiang Kong 2021Journal of Integrative Plant Biology2021,63,6:3
15Deformation and failure characteristics of sandstone under uniaxial compression using distributed fiber optic strain sensing显示文摘This paper investigates the deformation and fracture propagation of sandstone specimen under uniaxial compression using the distributed fiber optic strain sensing(DFOSS)technology.It shows that the DFOSS-based circumferential strains are in agreement with the data monitored with the traditional strain gage.The DFOSS successfully scans the full-field view of axial and circumferential strains on the specimen surface.The spatiotemporal strain measurement based on DFOSS manifests crack closure and elastoplastic deformation,detects initialization of microcrack nucleation,and identifies strain localization within the specimen.The DFOSS well observes the effects of rock heterogeneity on rock deformation.The advantage of DFOSS-based strain acquisition includes the high spatiotemporal resolution of signals and the ability of full-surface strain scanning.The introduction to the DFOSS technology yields a better understanding of the rock damage process under uniaxial compression.Lingfan Zhang Duoxing Yang Zhonghui Chen Aichun Liu 2020Journal of Rock Mechanics and Geotechnical Engineering2020,12,5:3
16Regional Moisture Source Changes Inferred from Late Holocene Stable Isotope Records显示文摘Qinghai Lake, China, is located near the northern limit of the East Asian summer monsoon (EASM) and thus is an ideal region for studies of past monsoonal changes. However, isotope records from this region reffect the combined effects of multiple climatic factors, and make climatic interpretations difficult. The authors use multi-proxy records, generated from the same sediment core from Qinghai Lake, to disentangle these multiple effects in isotope records and to infer EASM variability during the late Holocene. Records of leaf wax (C28) δD, lake carbonate δ18O and the Dunde ice core δ18O all indicate a millennial-scale depletion of mean isotopic values at ~1500–1250 years before present. Compared with independent lake temperature and salinity records, the authors suggest that this depletion of long-term mean isotopic values must have resulted from changes in moisture sources in this region. In contrast, the authors attribute high-frequency (centennial timescale) C28 δD and ice core δ18O variability dominantly to a temperature effect. The multi- proxy records provide a coherent picture in that many aspects of this regional climate (temperature, dryness, and moisture source) are strongly linked to the EASM variability.Zhonghui LIU Andrew C.

17Formation and evolution of the tertiary carbonate reefs in the Madura Strait Basin of Indonesia显示文摘Analysis of 2 D seismic data over 4 500 km in length from the Madura Strait Basin in the East Java Sea reveals seismic re?ection characteristics of reefs and associated sedimentary bodies, including asymmetrical or symmetrical dome re?ections, slope progradational re?ections, chaotic re?ections and discontinuous strong re?ections inside the reef, which onlap the ?ank of the reef. It is concluded that the developmental paleo-environment of most reefs is mainly conducive to shallow marine carbonate platform facies and platform margin facies, based on well core data, variations in seismic facies and strata thickness.The formation and evolution of all reefs are primarily in?uenced by the tectonic framework of the Madura Strait Basin. Platform margin reefs are principally controlled by two types of structures: one is a series of E-W trending Paleogene normal faults, and the other is an E-W trending Neogene inversion structures. In addition, wave actions, tidal currents and other ocean currents play an accelerated role in sorting, rounding and redeposition for the accumulation and evolution of reefs. Tertiary reefs in the MSB can be divided into four types: 1) an open platform coral reef of Late Oligocene to Early Miocene, 2) a platform margin coral reef controlled by normal faults in Late Oligocene to Early Miocene, 3) a platform margin Globigerina moundreef controlled by a 'hidden' inversion structure in Early Pliocene, and 4) a platform margin Globigerina mound-reef controlled by thrust faults in the early Pliocene. Patterns of the formation and evolution of reefs are also suggested.RAN Weimin LUAN Xiwu LU Yintao LIU Hong YANG Jiajia ZHAO Yang HE Wenchang YAN Zhonghui 2019Journal of Oceanology and Limnology2019,37,1:3
18A LOSSLESS COMPRESSION ALGORITHM OF REMOTE SENSING IMAGE FOR SPACE APPLICATIONS显示文摘A simple and adaptive lossless compression algorithm is proposed for remote sensing image compression,which includes integer wavelet transform and the Rice entropy coder.By analyzing the probability distribution of integer wavelet transform coefficients and the characteristics of Rice entropy coder,the divide and rule method is used for high-frequency sub-bands and low-frequency one.High-frequency sub-bands are coded by the Rice entropy coder,and low-frequency coefficients are predicted before coding.The role of predictor is to map the low-frequency coefficients into symbols suitable for the entropy coding.Experimental results show that the average Compression Ratio(CR) of our approach is about two,which is close to that of JPEG 2000.The algorithm is simple and easy to be implemented in hardware.Moreover,it has the merits of adaptability,and independent data packet.So the algorithm can adapt to space lossless compression applications.Sui Yuping Yang Chengyu Liu Yanjun Wang Jun Wei Zhonghui He Xin 2008Journal of Electronics(China)2008,25,5:3
