| 5 | Development of Hydro-Informatic Modelling System and its application显示文摘The understanding of hydrological cycle is the core of hydrology and the scientific base of water resources management. Meanwhile, simulation of hydrological cycle has long been regarded as an important tool for the assessment, utilization and protection of water resources. In this paper, a new tool named Hydro-Informatic Modelling System (HIMS) has been developed and introduced with case studies in the Yellow River Basin in China and 331 catchments in Australia. The case studies showed that HIMS can be employed as an integrated platform for hydrological simulation in different regions. HIMS is a modular based framework of hydrological model designed for different utilization such as flood forecasting, water resources planning and evaluating hydrological impacts of climate change and human activities. The unique of HIMS is its flexibility in providing alternative modules in the simulation of hydrological cycle, which successfully overcome the difficulties in the availability of input data, the uncertainty of parameters, and the difference of rainfall-runoff processes. The modular based structure of HIMS makes it possible for developing new hydrological models by the users. | LIU ChangMing WANG ZhongGen ZHENG HongXing ZHANG Lu WU XianFeng | 2008 | Science China(Technological Sciences)2008,51,4: | 9 |
| 6 | Soil temperature and moisture sensitivities of soil CO_2 efflux before and after tillage in a wheat field of Loess Plateau,China显示文摘As a conventional farming practice,tillage has lasted for thousands of years in Loess Plateau,China.Although recent studies show that tillage is a prominent culprit to soil carbon loss in croplands,few studies have investigated the influences of tillage on the responses of soil CO2 efflux(SCE) to soil temperature and moisture.Using a multi-channel automated CO2 efflux chamber system,we measured SCE in situ continuously before and after the conventional tillage in a rain fed wheat field of Loess Plateau,China.The changes in soil temperature and moisture sensitivities of SCE,denoted by the Q10 value and linear regression slope respectively,were compared in the same range of soil temperature and moisture before and after the tillage.The results showed that,after the tillage,SCE increased by 1.2-2.2 times;the soil temperature sensitivity increased by 36.1%-37.5%;and the soil moisture sensitivity increased by 140%-166%.Thus,the tillage-induced increase in SCE might partially be attributed to the increases in temperature and moisture sensitivity of SCE. | Hongxing Zhang Xiaoke Wang Zongwei Feng Junzhu Pang Fei Lu Zhiyun Ouyang Hua Zheng Wenzhao Liu Dafeng Hui | 2011 | Journal of Environmental Sciences2011,23,1: | 7 |
| 7 | Malus-metasurface-assisted polarization multiplexing显示文摘Polarization optics plays a pivotal role in diffractive,refractive,and emerging flat optics,and has been widely employed in contemporary optical industries and daily life.Advanced polarization manipulation leads to robust control of the polarization direction of light.Nevertheless,polarization control has been studied largely independent of the phase or intensity of light.Here,we propose and experimentally validate a Malus-metasurface-assisted paradigm to enable simultaneous and independent control of the intensity and phase properties of light simply by polarization modulation.The orientation degeneracy of the classical Malus’s law implies a new degree of freedom and enables us to establish a one-to-many mapping strategy for designing anisotropic plasmonic nanostructures to engineer the Pancharatnam–Berry phase profile,while keeping the continuous intensity modulation unchanged.The proposed Malus metadevice can thus generate a near-field greyscale pattern,and project an independent far-field holographic image using an ultrathin and single-sized metasurface.This concept opens up distinct dimensions for conventional polarization optics,which allows one to merge the functionality of phase manipulation into an amplitudemanipulation-assisted optical component to form a multifunctional nano-optical device without increasing the complexity of the nanostructures.It can empower advanced applications in information multiplexing and encryption,anti-counterfeiting,dual-channel display for virtual/augmented reality,and many other related fields. | Liangui Deng Juan Deng Zhiqiang Guan Jin Tao Yang Chen Yan Yang Daxiao Zhang Jibo Tang Zhongyang Li Zile Li Shaohua Yu Guoxing Zheng Hongxing Xu Cheng-Wei Qiu Shuang Zhang | 2020 | Light(Science & Applications)2020,9,1: | 7 |
| 8 | Niobium alloying effect in high carbon equivalent grey cast iron显示文摘The effect of niobium on the formation of NbC phase and solidification structure in high carbon equivalent grey cast iron was investigated.The experimental results indicated that an increase in the niobium content is favorable to refining the graphite and eutectic cell;and the pearlite lamellar spacing is reduced.Based on the thermodynamic calculation the formation of NbC is prior to the eutectic reaction.The reduction in the pearlite lamellar spacing is mainly attributed to the decrease of eutectic temperature with the addition of niobium.Additionally,properties including hardness and wear resistance were improved after the addition of niobium. | Zhou Wenbin Zhu Hongbo Zheng Dengke Zheng Hongxing Hua Qin Zhai Qijie | 2011 | China Foundry2011,8,1: | 7 |
| 9 | Effect of temperature field on solidification structure of pure Al under pulse magneto-oscillation显示文摘This article discusses the effect of temperature field on the Pulse Magneto-Oscillation(PMO) induced solidification refinement of pure aluminium to provide more information for the industrial application of the PMO solidification technology.The temperature field is altered mainly by applied variable cooling conditions and pulse parameters.Experimental results show that the refinement effect in the case of full sand mould applied is weakened with the decreasing of cooling rate,however,in the alternative case,the sand mould whose sand bottom was replaced by a graphite block is favorable to the survival of equiaxed nucleus.The refinement mechanism is discussed in terms of the relationship between temperature field and the formation process of solidified structure.The formation or survival of nucleus depends on both temperature field and Joule heat produced by PMO,both low pulse frequency and high pulse current were experimentally confirmed to be effective;and PMO was demonstrated high potential in industrial application. | Li Bo Yin Zhenxing Gong Yongyong LJ Kefeng Zheng Hongxing Li Renxing Zhai Qijie | 2011 | China Foundry2011,8,2: | 6 |

| 11 | Soil warming effect on net ecosystem exchange of carbon dioxide during the transition from winter carbon source to spring carbon sink in a temperate urban lawn显示文摘The significant warming in urban environment caused by the combined effects of global warming and heat island has stimulated widely development of urban vegetations.However,it is less known of the climate feedback of urban lawn in warmed environment.Soil warming effect on net ecosystem exchange(NEE)of carbon dioxide during the transition period from winter to spring was investigated in a temperate urban lawn in Beijing,China.The NEE(negative for uptake)under soil warming treatment(temperature was about 5°C higher than the ambient treatment as a control)was-0.71 μmol/(m2·sec),the ecosytem was a CO2 sink under soil warming treatment,the lawn ecosystem under the control was a CO2 source(0.13μmol/(m2·sec)),indicating that the lawn ecosystem would provide a negative feedback to global warming.There was no significant effect of soil warming on nocturnal NEE(i.e.,ecosystem respiration),although the soil temperature sensitivity(Q10) of ecosystem respiration under soil warming treatment was 3.86,much lower than that in the control(7.03).The CO2 uptake was significantly increased by soil warming treatment that was attributed to about 100% increase of α(apparent quantum yield)and Amax(maximum rate of photosynthesis).Our results indicated that the response of photosynthesis in urban lawn is much more sensitive to global warming than respiration in the transition period. | Xiaoping Zhou Xiaoke Wang Lei Tong Hongxing Zhang Fei Lu Feixiang Zheng Peiqiang Hou WenzhiSong Zhiyun Ouyang | 2012 | Journal of Environmental Sciences2012,24,12: | 4 |
| 12 | PADI3 induces cell cycle arrest via the Sirt2/AKT/p21 pathway and acts as a tumor suppressor gene in colon cancer显示文摘Objective:As a member of the peptidyl arginine deiminase(PAD)family,PADI3 is weakly expressed in colon cancer tissues and highly expressed in adjacent colon cancer tissues.However,the role of PADI3 in colon cancer is unclear.In this study,we investigated the function and molecular mechanism of PADI3 in colon cancer tumorigenesis.Methods:Western blot and real-time PCR were used to detect the expression levels of several genes.CCK-8,flow cytometry(FCM)and colony formation assays were used to examine cell proliferation,the cell cycle and colony formation ability.RNAsequencing analysis was used to study the molecular mechanism of PADI3 in tumorigenesis.A truncation mutation experiment was performed to determine the key functional domain of PADI3.Results:PADI3 overexpression inhibited cell proliferation and colony formation and led to G1 phase arrest in both HCT116(originating from primary colon cancer)and LoVo(originating from metastatic tumor nodules of colon cancer)cells.PADI3-expressing HCT116 cells had a lower tumor formation rate and produced smaller tumors than control cells.PADI3 significantly decreased Sirtuin2(Sirt2)and Snail expression and AKT phosphorylation and increased p21 expression,and Sirt2 overexpression partly reversed the effects induced by PADI3 overexpression.Immunocytochemistry showed that PADI3 is mainly localized in the cytoplasm.Truncation mutation experiments showed that the C-domain is the key domain involved in the antitumor activity of PADI3.Conclusions:PADI3 suppresses Snail expression and AKT phosphorylation and promotes p21 expression by downregulating Sirt2 expression in the cytoplasm,and the C-domain is the key domain for its antitumor activity. | Xiaotian Chang Zhengbin Chai Jiaorui Zou Hongxing Wang Yao Wang Yabing Zheng Hui Wu Chunyan Liu | 2019 | Cancer Biology & Medicine2019,16,4: | 4 |
| 13 | Automatic Matching of Multi-scale Road Networks under the Constraints of Smaller Scale Road Meshes显示文摘In this paper,we propose a new method to achieve automatic matching of multi-scale roads under the constraints of smaller scale data.The matching process is:Firstly,meshes are extracted from two different scales road data.Secondly,several basic meshes in the larger scale road network will be merged into a composite one which is matched with one mesh in the smaller scale road network,to complete the N∶1(N>1)and 1∶1 matching.Thirdly,meshes of the two different scale road data with M∶N(M>1,N>1)matching relationships will be matched.Finally,roads will be classified into two categories under the constraints of meshes:mesh boundary roads and mesh internal roads,and then matchings between the two scales meshes will be carried out within their own categories according to the matching relationships.The results show that roads of different scales will be more precisely matched using the proposed method. | Hongxing PEI Renjian ZHAI Fang WU Jinghan LI Xianyong GONG Zheng WU | 2019 | Journal of Geodesy and Geoinformation Science2019,2,4: | 4 |
| 14 | High-temperature phase transition behavior and magnetocaloric effect in a sub-rapidly solidified La–Fe–Si plate produced by centrifugal casting显示文摘A sub-rapidly solidified La Fe_(11.6)Si_(1.4)plate was fabricated directly from liquid by centrifugal casting method.The phase constitution,microstructure and magnetocaloric effect were investigated using backscatter scanning electron microscopy,X-ray diffraction,differential scanning calorimetry and physical property measurement system.When the plate was annealed at 1373 K,1 phase was formed by a solid-state peritectoid reaction.A first-order magnetic phase transition occurred in the vicinity of188 K,and the effective refrigeration capacities reached 203.5 J/kg and 209.7 J/kg in plates annealed for1 h and 3 h,respectively,under a magnetic field change of 3 T.It is suggested that centrifugal casting may become a new approach to prepare high-performance La–Fe–Si magnetocaloric plates for practical applications,which could largely accelerate the formation of 1 phase during high-temperature heat-treatment process due to refined and homogeneous honeycombed microstructure. | Zhishuai Xu Yuting Dai Yue Fang Zhiping Luo Ke Han Changjiang Song Qijie Zhai Hongxing Zheng | 2018 | Journal of Materials Science & Technology2018,34,8: | 4 |

| 16 | Self‐suspended rare‐earth doped up‐conversion luminescent waveguide:propagating and directional radiation显示文摘Near-infrared excited rare-earth(RE)-doped up-conversion(UC)-luminescent materials have attracted enormous attention because of their unique emission properties,such as narrow emission bands,long luminescence lifetimes,and multiple colors.However,current development of RE-doped luminescent material is hindered by weak and narrowband absorption problems and low photon-conversion quantum efficiencies.In addition to conventional approaches to enhance fluorescence intensity,controlling emission directivity to improve detection efficiency has become a promising approach to obtain higher luminescence brightnesses.In this paper,a self-suspended RE-doped UC luminescent waveguide is designed to realize directional emissions.Benefitting from the special morphology of the crown-like NaYF4:Yb3+/Er3+microparticle,the points contact between the waveguide and substrate can be obtained to decrease energy loss.An attractive UC luminescent pattern accompanied by powerful and controllable directional emissions is observed,and the spatial emission angle and intensity distribution are explored and analyzed in detail by introducing Fourier imaging detection and simulation.This work provides a new method for achieving controllable directional fluorescence emissions and obtaining improved detection efficiency by narrowing emission directivity,which has potential applications in 3-dimensional displays and micro-optoelectronic devices,especially when fabricating self-fluorescence micron lasers. | Changjian Zhang Chengyun Zhang Zhenglong Zhang Tao He Xiaohu Mi Ting Kong Zhengkun Fu Hairong Zheng Hongxing Xu | 2020 | Opto-Electronic Advances2020,3,6: | 3 |
| 17 | Change of the solar radiation and its causes in the Haihe River Basin and surrounding areas显示文摘Solar radiation is an important driving force for the formation and evolution of climate system. Analysis of change in solar radiation is helpful in understanding mechanism of climate change. In this study, the temporal and spatial variations of solar radiation and the cause of the change in solar radiation have been analyzed based on meteorological data from 46 national meteorological stations and aerosol index data from TOMS over the Haihe River Basin and surrounding areas. The results have shown that solar radiation and direct radiation significantly decreased, while scattered radiation increased during the period 1957–2008. Spatially, the decreasing trend of solar radiation was more and more significant from low population density areas to high population density areas. The spatial distribution of increase in aerosol index is consistent with that of decrease in solar radiation. The increase in aerosols resulting from human activities was an important reason for the decrease in solar radiation. | LIU Changming LIU Xiaomang ZHENG Hongxing ZENG Yan | 2010 | Journal of Geographical Sciences2010,20,4: | 3 |
| 18 | A urinary proteomic landscape of COVID-19 progression identifies signaling pathways and therapeutic options显示文摘Signaling pathway alterations in COVID-19 of living humans as well as therapeutic targets of the host proteins are not clear.We analyzed 317 urine proteomes,including 86 COVID-19,55 pneumonia and 176 healthy controls,and identified specific RNA virus detector protein DDX58/RIG-I only in COVID-19 samples.Comparison of the COVID-19 urinary proteomes with controls revealed major pathway alterations in immunity,metabolism and protein localization.Biomarkers that may stratify severe symptoms from moderate ones suggested that macrophage induced inflammation and thrombolysis may play a critical role in worsening the disease.Hyper activation of the TCA cycle is evident and a macrophage enriched enzyme CLYBL is up regulated in COVID-19 patients.As CLYBL converts the immune modulatory TCA cycle metabolite itaconate through the citramalyl-CoA intermediate to acetyl-CoA,an increase in CLYBL may lead to the depletion of itaconate,limiting its anti-inflammatory function.These observations suggest that supplementation of itaconate and inhibition of CLYBL are possible therapeutic options for treating COVID-19,opening an avenue of modulating host defense as a means of combating SARS-CoV-2 viruses. | Yuntao Liu Lan Song Nairen Zheng Jinwen Shi Hongxing Wu Xing Yang Nianci Xue Xing Chen Yimin Li Changqing Sun Cha Chen Lijuan Tang Xiaotian Ni Yi Wang Yaling Shi Jianwen Guo Guangshun Wang Zhongde Zhang Jun Qin | 2022 | Science China(Life Sciences)2022,65,9: | 1 |
| 19 | Design of a Transverse-flux Permanent-magnet Linear Generator and Controller for Use with a Free-piston Stirling Engine显示文摘Transverse-flux with high efficiency has been applied in Stirling engine and permanent magnet synchronous linear generator system,however it is restricted for large application because of low and complex process.A novel type of cylindrical,non-overlapping,transverse-flux,and permanent-magnet linear motor(TFPLM) is investigated,furthermore,a high power factor and less process complexity structure research is developed.The impact of magnetic leakage factor on power factor is discussed,by using the Finite Element Analysis(FEA) model of stirling engine and TFPLM,an optimization method for electro-magnetic design of TFPLM is proposed based on magnetic leakage factor.The relation between power factor and structure parameter is investigated,and a structure parameter optimization method is proposed taking power factor maximum as a goal.At last,the test bench is founded,starting experimental and generating experimental are performed,and a good agreement of simulation and experimental is achieved.The power factor is improved and the process complexity is decreased.This research provides the instruction to design high-power factor permanent-magnet linear generator. | ZHENG Jigui HUANG Yuping WU Hongxing ZHENG Ping | 2016 | Chinese Journal of Mechanical Engineering2016,29,4: | 1 |
