| 3 | Schistosoma japonicum infection induces macrophage polarization显示文摘The role of macrophages(Mφ)as the first line of host defense is well accepted.These cells play a central role in orchestrating crucial functions during schistosomal infection.Thus,understanding the functional diversity of these cells in the process of infection as well as the mechanisms underlying these events is crucial for developing disease control strategies.In this study,we adopted a Mφpolarization recognition system.Ml macrophage was characterized by expressing CD16/32,IL-12 and iNOS.M2 macrophage was characterized by expressing CD206,IL-10 and arg-1.In vivo(mouse peritoneal macrophages of different infection stages were obtained)and in vitro(different 5.japonicum antigens were used to stimulate RAW264.7)were characterized by using the above mentioned system.NCA and ACA stimulated RAW264.7 express significantly higher levels of IL-12 while significantly higher levels of IL-10 were detected after soluble egg antigen(SEA)stimulation.The results showed that dramatic changes of antigen in the microenvironment before and after egg production led to macrophage polarization.Furthermore,through TLR blocking experiments,the TLR4 signaling pathway was found to play a role in the process of macrophage polarization toward Ml.Our data suggest that macrophage polarization during S.japonicum infection had significant effects on host immune responses to S.japonicum. | Jingwei Xu Hao Zhang Lin Chen Donghui Zhang Minjun Ji Haiwei Wu Guanling Wu | 2014 | The Journal of Biomedical Research2014，28，4： | 20 |
| 4 | Soil salt leaching under different irrigation regimes: HYDRUS-1D modelling and analysis显示文摘Field irrigation experiments were conducted in the Hetao Irrigation District of Inner Mongolia,China,to study the effects of irrigation regimes on salt leaching in the soil profile.The data were used to calibrate and validate the HYDRUS-1D model.The results demonstrated that the model can accurately simulate the water and salt dynamics in the soil profile.The HYDRUS-1D model was then used to simulate 15 distinct irrigation scenarios.The results of the simulation indicated that irrigation amount did not have a significant effect on soil water storage but that increases in irrigation amount could accelerate salt leaching.However,when the irrigation amount was larger than 20 cm,the acceleration was not obvious.Compared with irrigating only once,intermittent irrigation had a better effect on increasing soil water storage and salt leaching,but excessive irrigation times and intervals did not improve salt leaching.In addition,we found that the irrigation regime of 20 cm,irrigated twice at 1-d intervals,might significantly increase salt leaching in the plough layer and decrease the risks of deep seepage and groundwater contamination. | WenZhi ZENG Chi XU JingWei WU JieSheng HUANG | 2014 | Journal of Arid Land2014，6，1： | 20 |

| 6 | Design of integrated radar and communication system based on MIMO-OFDM waveform显示文摘Orthogonal frequency division multiplexing(OFDM)waveform enables radar and communication functions simultaneously, which encounters low angle resolution and poor data rate for traditional single input single output(SISO) systems. To solve these problems, an integrated radar and communication system(IRCS) with multiple input multiple output(MIMO) OFDM waveform is proposed. The different limitations of radar and communication in designing such a system are investigated. Then, an optimization problem is devised to obtain suitable system parameters, including the number of subcarriers, subcarrier spacing, number of symbols,pulse repetition frequency(PRF) and length of cyclic prefix(CP).Finally, to satisfy the requirements of both radar and communication, the IRCS parameters are derived in three typical cases.Several numerical results are presented to illustrate the demands of radar and communication, inconsistent or consistent, for the IRCS parameters and the superiority of the proposed system. | Yongjun Liu Guisheng Liao Zhiwei Yang Jingwei Xu | 2017 | Journal of Systems Engineering and Electronics2017，28，4： | 16 |
| 7 | In-situ incorporation of Copper (Ⅱ) porphyrin functionalized zirconium MOF and TiO2 for efficient photocatalytic CO2 reduction显示文摘As one of the highly effective methods to prepare catalysts for photocatalytic reduction of CO2 into valueadded chemicals,using metalloporphyrin as light-harvesting mixed ligand to modify metal-organic framework(MOF)is very valuable since it can greatly improve the prophyrin dispersibility and consequently inhibit its potential agglomeration.Herein,we employed a one-pot synthetic strategy to chemically immobilize Cu(II)tetra(4-carboxylphenyl)porphyrin(CuTCPP)into UiO-66 MOF structure through coordination mode.Meanwhile,in-situ growth of TiO2 nanoparticles onto the MOF is actualized with the generation of CuTCPP c UiO-66/TiO2(CTU/TiO2)composites.Under Xe lamp irradiation(λ>300 nm),the catalytic result presents that an optimal value of 31.32 μmol g^-1 h^-1 CO evolution amount,about 7 times higher than that of pure TiO2 was obtained through the photocatalysis.It is supposed owning to a consistent augment of light absorption derived from chemically implanted porphyrin derivative,which is simultaneously functioning with an efficacious separation of photo-induced carries given by the newly engendered composites between MOF and TiO2,an effective catalytic activity and approving recyclability of CTU/TiO2 can be achieved in the photocatalytic reduction of CO2 into CO. | Lei Wang Pengxia Jin Shuhua Duan Houde She Jingwei Huang Qizhao Wang | 2019 | Science Bulletin2019，64，13： | 16 |
| 8 | Parallel Control for Optimal Tracking via Adaptive Dynamic Programming显示文摘This paper studies the problem of optimal parallel tracking control for continuous-time general nonlinear systems.Unlike existing optimal state feedback control,the control input of the optimal parallel control is introduced into the feedback system.However,due to the introduction of control input into the feedback system,the optimal state feedback control methods can not be applied directly.To address this problem,an augmented system and an augmented performance index function are proposed firstly.Thus,the general nonlinear system is transformed into an affine nonlinear system.The difference between the optimal parallel control and the optimal state feedback control is analyzed theoretically.It is proven that the optimal parallel control with the augmented performance index function can be seen as the suboptimal state feedback control with the traditional performance index function.Moreover,an adaptive dynamic programming(ADP)technique is utilized to implement the optimal parallel tracking control using a critic neural network(NN)to approximate the value function online.The stability analysis of the closed-loop system is performed using the Lyapunov theory,and the tracking error and NN weights errors are uniformly ultimately bounded(UUB).Also,the optimal parallel controller guarantees the continuity of the control input under the circumstance that there are finite jump discontinuities in the reference signals.Finally,the effectiveness of the developed optimal parallel control method is verified in two cases. | Jingwei Lu Qinglai Wei Fei-Yue Wang | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，6： | 16 |
| 9 | Comparison of the Global Energy Cycle between Chinese Reanalysis Interim and ECMWF Reanalysis显示文摘The global energy cycle is a diagnostic metric widely used to gauge the quality of datasets. In this paper, the 'Mixed Space-Time Domain' method for diagnosis of energy cycle is evaluated by using newly developed datasets-the Chinese Reanalysis Interim (CRAI) and ECMWF Reanalysis version 5 (ERA5), over a 7-yr period (2010-16) on seasonal and monthly timescales. The results show that the energy components calculated from the two reanalysis datasets are highly consistent;however, some components in the global energy integral from CRAI are slightly larger than those from ERA5. The main discrepancy in the energy components stems from the conversion of baroclinic process, whereas the dominant difference originates from the conversion from stationary eddy available potential energy to stationary eddy kinetic energy (CES), which is caused by systematic differences in the temperature and vertical velocity in low-mid latitudes of the Northern Hemisphere and near the Antarctic, where there exist complex terrains. Furthermore, the monthly analysis reveals that the general discrepancy in the temporal variation between the two datasets also lie mainly in the CES as well as corresponding generation and dissipation rates. | Bin ZHAO Bo ZHANG Chunxiang SHI Jingwei LIU Lipeng JIANG | 2019 | Journal of Meteorological Research2019，33，3： | 14 |
| 10 | Characteristics and Origin of Tight Oil Accumulations in the Upper Triassic Yanchang Formation of the Ordos Basin,North-Central China显示文摘The Upper Triassic oil accumulations in the Ordos Basin is the most successful tight oil play in China,with average porosity values of less than 10% and permeability values below 1.0 mD.This study investigated the geological characteristics and origin of the tight oil accumulations in the Chang 6 member of the Upper Triassic Yanchang Formation in the Shanbei area based on over 50,000 petrological,source-rock analysis,well logging and production data.The tight oil accumulation of the Chang 6 member is distributed continuously in the basin slope and the centre of the basin.The oilwater relationships are complex.Laumontite dissolution pores are the most important storage spaces,constituting 30%-60% of total porosity and showing a strong positive relationship with oil production.The pore-throat diameter is less than 1 μm,and the calculated critical height of the oil column is much larger than the tight sand thickness,suggesting that the buoyancy was probably of limited importance for oil migration.The pressure difference between the source rocks and sandstone reservoirs is inferred to have provided driving force for hydrocarbon migration.Two factors of source-reservoir configuration and laumontite dissolution contributed to the formation of the Chang 6 tight oil accumulations.Intense hydrocarbon generation and continuous sand bodies close to the hydrocarbon kitchen are the foundation for the large-scale oil distribution.Dissolution of feldspar-laumontite during the process of organic matter evolution generated abundant secondary pores and improved the reservoir quality. | WU Songtao ZOU Caineng ZHU Rukai YAO Jingli TAO Shizhen YANG Zhi ZHAI Xiufen CUI Jingwei LIN Senhu | 2016 | Acta Geologica Sinica(English Edition)2016，90，5： | 13 |
| 11 | High-precision Dating and Geological Significance of Chang 7 Tuff Zircon of the Triassic Yanchang Formation, Ordos Basin in Central China显示文摘The Ordos Basin, as the second largest petroliferous basin of China, contains abundant oil and gas resources, oil shale, and sandstone-type uranium mineral resources. Chang 7 shale is not only the major source rock of the Mesozoic petroliferous system of the Basin, but is also crucial in determining the space-time distribution relationship of the shale section for the effective exploration and development of the Basin's oil and gas resources. To obtain a highly precise age of the shale development section, we collected tuff samples from the top and bottom profile of the Chang 7 Member, Yishi Village, Yaoqu Town, Tongchuan District, on the southern margin of the Ordos Basin and performed high-precision chemical abrasion(CA)–isotope dilution(ID)–thermal ionization mass spectrometry(TIMS) zircon U-Pb dating on the basis of extensive laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS) zircon U-Pb dating data. Our results show the precise ages of the top and bottom zircon in the Chang 7 shale to be 241.06±0.12 Ma and 241.558±0.093 Ma, respectively. We first obtained Chang 7 age data with Grade 0.1-Ma precision and then determined the age of the shale development in the Chang 7 Member to be the early-Middle Triassic Ladinian. This result is supported by paleontological evidence. The deposition duration of the Chang 7 shale is 0.5 Ma with an average deposition rate of the shale section being 5.3 cm/ka. Our research results provide time scale and basic data for further investigation of the basin–mountain coupling relation of the shale section, the sedimentary environment and volcanic ash and organic-matter-rich shale development relation, and the organism break-out and organic-matter enrichment mechanism. | ZHU Rukai CUI Jingwei DENG Shenghui LUO Zhong LU Yuanzheng QIU Zhen | 2019 | Acta Geologica Sinica(English Edition)2019，93，6： | 13 |
| 12 | Effect of Bushenwenyanghuayu decoction on nerve growth factor and bradykinin/bradykinin B_1 receptor in a endometriosis dysmenorrhea mouse model显示文摘OBJECTIVE:To observe the effects of Bushenwenyanghuayu decoction(BD),a Traditional Chinese Medicine(TCM),on the serum concentration of nerve growth factor(NGF) and bradykinin(BK),and protein and mRNA levels of NGF and bradykinin B_1receptor(BKB1R) in a mouse model of endometriosis dysmenorrhea.METHODS:Seventy-five experimental female BALB/c mice were randomly divided into five groups,15 mice each:sham,model,BD high dose(61.67 g/kg),BD low dose(15.42 g/kg),and gestrinone(0.4 mg/kg) groups.All the mice except for those in the sham group underwent auto-transplantation surgery and were gavaged estradiol valerate(0.5 mg/kg,daily for 12 days) after surgery.On the 12 th day,1 h after administration,writhing response was induced by intraperitoneal injection of oxytocin at 2 U/mouse.The writhing frequency and latency were recorded and the volume of the ectopic foci was measured.The concentration of serum NGF and BK was detected by enzyme-linked immunosorbent assay,the protein expression of NGF and BKB1 R was tested by immunohistochemistry and western blotting,and NGF and BKB1 R mRNAs were detected by real-time PCR.RESULTS:Compared with the model group,the volume of the ectopic foci in the treatment groups was significantly lower(P < 0.01),the writhing frequency was decreased(P < 0.05),and the writhing latency was prolonged(P < 0.01).Compared with the sham group,serum NGF and BK levels in the model group were significantly increased(P <0.01).There were positive correlations for writhing frequency among the NGF and BK groups(P <0.01).The serum NGF and BK levels were significantly lower in the treatment groups than the model group(P < 0.05).The protein expression of NGF,BKB1 R was significantly decreased in the treatment groups compared with the model group(P < 0.01).NGF and BKB1 R mRNA expression was significantly decreased in the treatment groups compared with the model group(P < 0.01).CONCLUSION:NGF and BK/BKB1 R may play an important role in the development of endometriosis-associated dysmenorrhea,and BD was found to inhibit the development of endometriosis and relieve dysmenorrhea by influencing NGF and BK/BKB1 R mRNA and protein levels. | Chen Jingwei Du Huilan Tong Ruixiao Yang Hua Ma Huirong | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 12 |
| 13 | Spatial gradient distributions of thermal shock-induced damage to granite显示文摘In this study,we attempted to investigate the spatial gradient distributions of thermal shock-induced damage to granite with respect to associated deterioration mechanisms.First,thermal shock experiments were conducted on granite specimens by slowly preheating the specimens to high temperatures,followed by rapid cooling in tap water.Then,the spatial gradient distributions of thermal shock-induced damage were investigated by computed tomography(CT)and image analysis techniques.Finally,the influence of the preheating temperature on the spatial gradients of the damage was discussed.The results show that the thermal shock induced by rapid cooling can cause more damage to granite than that induced by slow cooling.The thermal shock induced by rapid cooling can cause spatial gradient distributions of the damage to granite.The damage near the specimen surface was at a maximum,while the damage inside the specimen was at a minimum.In addition,the preheating temperature can significantly influence the spatial gradient distributions of the thermal shock-induced damage.The spatial gradient distribution of damage increased as the preheating temperature increased and then decreased significantly over 600C.When the preheating temperature was sufficiently high(e.g.800C),the gradient can be ignored. | Lifeng Fan Jingwei Gao Xiuli Du Zhijun Wu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，5： | 11 |
| 14 | Oil filling history of the Bashituo Oilfield in the Markit Slope,SW Tarim Basin,China显示文摘The Markit Slope is an important area for the petroleum exploration in the Tarim Basin. Elucidation of the oil filling history of discovered oilfields has great significance for recognizing the accumulation processes of the whole region. Using molecular geochemistry, fluid inclusion techniques and basin modeling, we studied the oil filling process of the Bashituo Oilfield that is located in the west of the Markit Slope. The molecular migration indexes, such as the methyldibenzothiophene ratio (4-/1-MDBT), trimethylnaphthalene ratio (TMNr) and pyrrolic nitrogen compounds content, decrease from west to east, indicating that the charging direction and migration pathways are from west to east. Lithological analysis and homogenization temperatures of saline fluid inclusions accompanied with oil fluid inclusions suggest that two charging periods occurred in the Devonian oil reservoir. Combining the burial history and heating history of well BT4, Basinmod 1D software modeling shows the two oil filling periods are from 290 Ma to 285 Ma and from 10 Ma to 4 Ma, respectively, and later oil filling dominates. This study may be helpful to understand the accumulation process and provide useful references for oil and gas exploration in the Markit Slope. | Cui Jingwei Wang Tieguan Li Meijun Ou Guangxi Geng Feng Hu Jian | 2013 | Petroleum Science2013，10，1： | 11 |
| 15 | Accumulation of unconventional petroleum resources and their coexistence characteristics in Chang7 shale formations of Ordos Basin in central China显示文摘The Ordos Basin is the largest oil and gas producing basin in China, where tight oil, shale gas, oil shale, and other unconventional oil and gas resources have been found in the Chang7 subsection of the Triassic Yanchang Formation. However, the mechanism of formation and the distribution of unconventional oil and gas resources in the shale layers have not been systematically investigated until now. According to the type of unconventional oil and gas resources, main controlling factors, and the maturity, depth and abundance of organic matters, the shale oil and gas resources from Chang7 region are divided into five zones that include an outcrop-shallow oil shale zone, a middle-matured and medium-burial shale oil zone, a medium-matured and medium-burial in situ conversion process (ICP) shale oil zone, a high-maturity and deep-burial shale gas zone, and an adjacent-interbedded tight sandstone oil zone. By the distribution of resources, orderly evolution of oil and gas resources and coexistences in lacustrine shale formations have been put forward, and also a strategy of integrated exploration and development of resources in the shale formations is proposed. Overall, the outcome of this study may guide on the effective utilization of unconventional oil and gas resources in other shale formations. | Jingwei CUI Rukai ZHU Zhiguo MAO Shixiang LI | 2019 | Frontiers of Earth Science2019，13，3： | 11 |
| 16 | Characterstics of seasonal variations of leaf n-alkanesand n-alkenes in modern higher plants in Qingjiang, Hubei Province, China显示文摘On the basis of GC and GC-MS analyses, the seasonal variation of leaf lipids is observed in five plant species in Qingjiang in Hubei Province. The CPI values (carbon preference index) of n-alkanes decrease gradually from May to November, though the carbon number distributions and the predominant carbon number in an individual species keep unchanged. The declined CPI values might be caused by the leaf fading, which is further supported by a comparison of the defoliated leaves with the fresh leaves. This observation infers the CPI values of n-alkanes in Quaternary sediments can be used as a tool to index the humification, and thus the climatic and the environmental conditions. The plants analyzed here show a remarkable difference in n-alkanes abundance, suggesting their differential contribution to the n-alkanes identified in sediments. The abundance and the compound species of the n-alkenes detected in the plant leaves change greatly with the seasons due to the influence of temperature, with the least compounds being identified in August. | CUI JingWei HUANG JunHua XIE ShuCheng | 2008 | Chinese Science Bulletin2008，53，17： | 10 |
| 17 | The Asian Subtropical Westerly Jet Stream in CRA-40, ERA5, and CFSR Reanalysis Data:Comparative Assessment显示文摘The Asian subtropical westerly jet(AWJ) exerts crucial influences on Eurasian continent weather and climate. This paper analyzes the advantages and limitations of CRA-40, which is China's first generation 40-yr(1979–2018) global atmosphere and land reanalysis product, in describing the characteristics of AWJ, compared with the ECMWF Reanalysis version 5(ERA5) and NCEP Climate Forecast System Reanalysis(CFSR). The results show a close agreement across the three reanalyses on the whole.(1) In terms of climatology, overall differences of 200-h Pa zonal wind across the three reanalyses are within ± 0.5 m s^(-1)(i.e., ± 2%). Large differences with maxima of ± 2 m s^(-1)(±5%) appear over the Iranian Plateau and south of the Tibetan Plateau in the mid–upper troposphere in winter.(2) For seasonal cycle, the position and intensity of the AWJ centers in the three reanalyses are highly consistent, with correlation coefficient over 0.98. But there are some discrepancies in the zonal shift of the western AWJ center during the transition season.(3) On the interannual timescale, intensity of all AWJ centers varies consistently among the three reanalyses, while larger differences appear in their meridional displacement, especially in the eastern AWJ center.(4)For long-term variations, the three reanalyses all present a significant northward movement of the westerly jet axis in winter, and a southward displacement over central Asia(40°–80°E) and a northward migration over East Asia(80°–110°E) in summer. Thus, this study has provided confidence that CRA-40 has comparable performance with ERA5 and CFSR in depicting the characteristics of AWJ. | Xiaojing YU Lixia ZHANG Tianjun ZHOU Jingwei LIU | 2021 | Journal of Meteorological Research2021，35，1： | 10 |
| 18 | High-Performance Flexible Asymmetric Supercapacitor Based on CoAl-LDH and rGO Electrodes显示文摘A flexible asymmetric supercapacitor(ASC)based on a Co Al-layered double hydroxide(Co Al-LDH)electrode and a reduced graphene oxide(r GO) electrode was successfully fabricated. The Co Al-LDH electrode as a positive electrode was synthesized by directly growing Co Al-LDH nanosheet arrays on a carbon cloth(CC)through a facile hydrothermal method, and it delivered a specific capacitance of 616.9 F g^(-1)at a current density of1 A g^(-1). The r GO electrode as a negative electrode was synthesized by coating r GO on the CC via a simple dipcoating method and revealed a specific capacitance of110.0 F g^(-1)at a current density of 2 A g^(-1). Ultimately,the advanced ASC offered a broad voltage window(1.7 V)and exhibited a high superficial capacitance of1.77 F cm^(-2)at 2 m A cm^(-2)and a high energy density of0.71 m Wh cm^(-2)at a power density of 17.05 m W cm^(-2),along with an excellent cycle stability(92.9% capacitance retention over 8000 charge–discharge cycles). | Shuoshuo Li Pengpeng Cheng Jiaxian Luo Dan Zhou Weiming Xu Jingwei Li Ruchun Li Dingsheng Yuan | 2017 | Nano-Micro Letters2017，9，3： | 10 |

| 20 | Contributions of Local and Remote Atmospheric Moisture Fluxes to East China Precipitation Estimated from CRA-40 Reanalysis显示文摘China Meteorological Administration(CMA) recently released its 40-yr(1979–2018) global Chinese reanalysis(CRA-40) dataset. To assess performance of the CRA-40 data in quantifying the regional water cycle, contributions of local and remote atmospheric moisture fluxes to precipitation in East China derived from CRA-40 are compared with those derived from the ECMWF reanalysis version 5(ERA-5). Observed precipitation and evaporation data are also used for validation. As for mean precipitation, CRA-40 matches the observation better in winter and spring than in summer, with a larger wet bias(1.41 mm day^(-1)) in summer than that in ERA-5(0.97 mm day^(-1)), particularly over South China. The conservation of atmospheric water vapor over East China measured by CRA-40 is comparable to that of ERA-5. Both reanalyses show a dominant role of the remote moisture transport in the East China precipitation.In comparison, the annual precipitation induced by the moisture influx from the west of the study domain in CRA-40 is 80 mm less than that in ERA-5. The recycling ratio of annual mean precipitation in CRA-40 is approximately21.1%, slightly larger than that in ERA-5(20.1%). The maximum difference of each hydrological component between the two datasets appears in the summer horizontal moisture influx(3.57 ×10^(7) kg s^(-1);ERA-5 is larger) and winter runoff(1.84 ×10^(7) kg s^(-1);CRA-40 is larger). CRA-40 shows better performance than ERA-5 in capturing the interannual variability of precipitation over East China, as evinced by a higher correlation coefficient with the observation(0.77 versus 0.33). The trend of summer precipitation since 2011 is better reproduced in CRA-40. Both reanalyses show prominent contribution of the southern moisture influx to the interannual variation of precipitation. This study demonstrates the reliability of CRA-40 in representing the hydrological cycle over East China and provides a useful reference for future application of CRA-40 in water cycle studies. | Dan ZHAO Lixia ZHANG Tianjun ZHOU Jingwei LIU | 2021 | Journal of Meteorological Research2021，35，1： | 8 |
