| 4 | Achieving food security and high production of bioenergy crops through intercropping with efficient resource use in China显示文摘With high rates of food and nonrenewable fossil fuel consumption worldwide,we are facing great challenges in ensuring food and energy security to satisfy the world population.Intercropping,as an important and sustainable cropping practice in agroecosystems,has been widely practiced around the world.Many studies have shown that some plants can deliver high yields when intercropped with other plants.Here,we review the biological mechanisms in improving resource utilization efficiency and illustrate the practical application of intercropping in ensuring food and energy security through improving production.Identifying suitable energy plants for marginal land,land not suitable for food crops growth,is an effective strategy to acquire high production of bioenergy,thus removing competition between the use of land for food and energy.The effective application of intercropping provides a potential pathway for production of food crops and energy plants by improving resource use efficiency and resistance to environmental stress. | Yuanmei ZUO Zhenjiao ZHANG Caihong LIU Weina ZHANG | 2015 | Frontiers of Agricultural Science and Engineering2015,2,2: | 5 |

| 7 | Effects of irrigation regimes on soil NO_(3)^(-)-N, electrical conductivity and crop yield in plastic greenhouse显示文摘Developing water-saving irrigation regimes has important practical significance not only in alleviating the crucial water shortage,but also in controlling soil salinization for the protected cultivation in eastern China.A field study with six treatments was conducted to evaluate the effects of different irrigation regimes with subdrainage systems on the soil nitrate nitrogen,salinity and moisture,also evaluate the effects on tomato growth,fruit yield and irrigation water use efficiency(IWUE).The treatments were distinguished by three different irrigation amounts of 310 mm,360 mm and 410 mm,and two irrigation frequencies of 7 and 11 times.Results showed that the irrigation amount had significant effects on the soil NO_(3)^(-)-N and electric conductivity(EC).A positive correlation was detected between soil NO_(3)^(-)-N(x)and EC(y)at 0-20 m depth after harvest,with a linear equation of y=0.063x-0.670.Soil volumetric moisture at 0.10 m and 0.20 m depth was increased as the irrigation amount increased.Moreover,a higher amount of irrigation increased the fruit yield but reduced the IWUE of tomato.It was also found that smaller irrigation amounts combined with frequent intervals could increase fruit yield and IWUE.However,the fruit quality of tomato had a significant(p<0.05)negative correlation with irrigation amount.Therefore,the parameters of irrigation regime including the irrigation amount and intervals should be considered comprehensively in order to find a compromise between salinity control and irrigation water use efficiency improvement. | Tingting Chang Yujie Zhang Zhanyu Zhang Xiaohou Shao Weina Wang Jie Zhang Xu Yang Huilian Xu | 2019 | International Journal of Agricultural and Biological Engineering2019,12,1: | 5 |

| 9 | Polar, catalytic, and conductive CoSe2/C frameworks for performance enhanced S cathode in Li–S batteries显示文摘Lithium-sulfur battery(Li-S)is considered as one of the new-generation rechargeable batteries with high performance because of its extremely high theoretical capacity,energy density,environmental harmony and low cost.However,low electrical and ionic conductivity of sulfur,safety concerns and parasitic reaction generated by the dissolved polysulfide species in electrolyte hinder the commercialization of Li-S battery.Herein,we report a polyhedral porous structure comprising of carbon coating metal selenide nanoparticles(CoSe2/C),which could not only host sulfur for Li-S battery owing to its porous and conductive structure,but also mitigate the shuttle phenomenon by polysulfides adsorption and catalytic acceleration of redox kinetics.As a result,a performance enhanced CoSe2/C-S electrode for Li-S battery is achieved. | Bo Yuan Di Hua Xingxing Gu Yu Shen Li-Chun Xu Xiuyan Li Bing Zheng Jiansheng Wu Weina Zhang Sheng Li Fengwei Huo | 2020 | Journal of Energy Chemistry2020,29,9: | 5 |
| 10 | Enhancing the expansion of a plasma shockwave by crater-induced laser refocusing in femtosecond laser ablation of fused silica显示文摘The dynamics of plasma and shockwave expansion during two femtosecond laser pulse ablation of fused silica are studied using a time-resolved shadowgraph imaging technique. The experimental results reveal that during the second pulse irradiation on the crater induced by the first pulse, the expansion of the plasma and shockwave is enhanced in the longitudinal direction. The plasma model and Fresnel diffraction theory are combined to calculate the laser intensity distribution by considering the change in surface morphology and transient material properties. The theoretical results show that after the free electron density induced by the rising edge of the pulse reaches the critical density, the originally transparent surface is transformed into a transient high-reflectivity surface(metallic state). Thus, the crater with a concave-lens-like morphology can tremendously reflect and refocus the latter part of the laser pulse, leading to a strong laser field with an intensity even higher than the incident intensity. This strong refocused laser pulse results in a stronger laser-induced air breakdown and enhances the subsequent expansion of the plasma and shockwave. In addition, similar shadowgraphs are also recorded in the single-pulse ablation of a concave microlens, providing experimental evidence for the enhancement mechanism. | QINGSONG WANG LAN JIANG JINGYA SUN CHANGJI PAN WEINA HAN GUOYAN WANG HAO ZHANG COSTAS P.GRIGOROPOULOS YONGFENG LU | 2017 | Photonics Research2017,5,5: | 5 |
| 11 | Pathway-based analysis for genome-wide association studies of schizophrenia to provide new insight in schizophrenia study显示文摘Schizophrenia (SZ) is an inheritable complex mental disease. There have been several genome-wide association studies (GWASs) of SZ to identify novel genetic susceptibility factors. To further interpret SZ GWASs, pathway-based analysis (PBA), which considers the combined effect of variants and identifies pathways associated with traits, provides a feasible solution to discover the biological function and mechanism of SZ. Furthermore, to investigate the common pathways between SZ and bipolar disorder (BD) will help explore common mechanism between psychiatric phenotypes. We performed a PBA, called improved gene set enrichment analysis (i-GSEA), on 3 independent GWASs of SZ to identify pathways associated with SZ. The results were further compared to the BD-associated pathways identified by i-GSEA for 2 BD GWASs and from literature reports. Our analysis identified a highly statistically significant association between SZ and pathway 'substrate specific channel activity' in all 3 SZ GWASs (false discovery rate (FDR) < 0.05). This association has not been reported elsewhere before. This pathway was also identified by PBA for 2 independent BD GWASs. Our results suggest that pathway 'substrate specific channel activity' is statistically significantly associated with SZ, and SZ and BD share the common biological function and mechanism represented by this pathway. | ZHANG KunLin ZHANG LiuYan ZHANG WeiNa WANG Jing | 2011 | Chinese Science Bulletin2011,56,32: | 4 |
| 12 | Homoharringtonine synergy with oridonin in treatment of t(8;21) acute myeloid leukemia显示文摘Collaboration of c-KIT mutations with AML1-ETO (AE) has been demonstrated to induce t(8;21) acute myeloid leukemia (AML).Targeted therapies designed to eliminate AE and c-KIT oncoproteins may facilitate effective treatment of t(8;21) AML.Homoharringtonine (HHT) features activity against tumor cells harboring c-KIT mutations,whereas oridonin can induce t(8;21) AML cell apoptosis and AE cleavage.Therefore,studies should explore the efficacy of combination therapy with oridonin and HHT in t(8;21) AML.In this study,we investigated the synergistic effects and mechanism of oridonin combined with HHT in t(8;21) AML cell line and mouse model.The two drugs synergistically inhibited cell viability and induced significant mitochondrial membrane potential loss and apoptosis.Oridonin and HHT induced significant downregulation of c-KIT and its downstream signaling pathways and promoted AE cleavage.HHT increased intracellular oridonin concentration by modulating the expressions of MRP1 and MDR1,thus enhancing the effects of oridonin.The combination of oridonin and HHT prolonged t(8;21) leukemia mouse survival.In conclusion,oridonin and HHT exert synergistic effects against t(8;21) leukemia in vivo and in vitro,thereby indicating that their combination may be an effective therapy for t(8;21) leukemia. | Weina Zhang Ying Lu Tao Zhen Xinjie Chen Ming Zhang Ping Liu Xiangqin Weng Bing Chen Yueying Wang | 2019 | Frontiers of Medicine2019,13,3: | 4 |
| 13 | Anion intercalated layered-double-hydroxide structure for efficient photocatalytic NO remove显示文摘Due to the easily controllable interlayer anions, metal cation composition proportion and thickness, which is beneficial to modify surface chemical state and tune bandgap, layered double hydroxides(LDHs) have great promising potential for photocatalytic applications. In this study,we have successfully synthesized the ZnAl–LDH intercalated the single anion between ZnAl cationic interlayer without anionic impurities by using a facile calcining and reconstructing routes. The electron structure and surface chemical state of the prepared products have been investigated by combining the DFT calculation and experimental characterization methods. UV–vis DRS was used to certify the light absorption of the prepared products, and we performed the DFT calculation to demonstrate the density of state and activation of reactant. These results suggested that the ZnAl–LDH–CO3 possessed the more proper band structure and superior ability to activate NO and O2 for accelerating the photocatalytic NO oxidation activity. Moreover, the in situ DRIFTS with dynamically monitoring intermediates and products over the ZnAl–LDH–CO3 was adopted to declare the photocatalytic NO oxidized process during the photocatalytic reaction process. This work illustrated the influence of different interlayer anions to the electron structure and surface chemical state of ZnAl–LDH structure through the experimental verification combined DFT calculation and the photocatalytic NO oxidized process via in situ DRIFTS analyzing, which would provide a novel way to design and fabricate the efficient photocatalysis, and understand the reaction process. | Wangchen Huo Tong Cao Xiaoying Liu Weina Xu Biqin Dong Yuxin Zhang Fan Dong | 2019 | Green Energy & Environment2019,4,3: | 4 |
| 14 | The effect of pmpR on the type Ⅲ secretion system in Pseudomonas aeruginosa显示文摘The type III secretion system(T3SS) plays important roles in Pseudomonas aeruginosa pathogenicity.Previously,we reported that the uncharacterized protein PmpR could regulate pqsR,an important regulator in the quorum-sensing system,by directly binding to its promoter region.As the T3SS is controlled by the quorum-sensing system,here,we investigated the relationship between PmpR and the T3SS.Our data showed that expression of the T3SS genes exoS,exoY,exoT,and exsD was dramatically increased in a pmpR-deletion mutant compared with that in the wild-type P.aeruginosa strain PAO1.Data from DNA mobility assays indicated that PmpR affects the T3SS indirectly.It is unlikely that PmpR controls the T3SS via the Pseudomonas quinolone signal(PQS) because the PQS negatively regulates the T3SS,while pmpR negatively regulates the PQS.The effect of PmpR on the T3SS seems to be independent of the PQS;further investigation is required to uncover the underlying regulatory pathways. | LIANG HaiHua KONG WeiNa SHEN Tuo DUAN JiaLi DUAN KangMin | 2012 | Chinese Science Bulletin2012,57,19: | 4 |
| 15 | Effects of compound microbial inoculant treated wastewater irrigation on soil nutrients and enzyme activities显示文摘Wastewater treated by compound microbial inoculant(CMI)in agricultural irrigation can enrich soil fertility and decompose the possible pollutants.In this study,a greenhouse experiment using tomato as the model crop was performed to investigate the effects of treated wastewater irrigation on soil nutrients and enzymes.For this purpose,certain parameters were measured,including soil total nitrogen(N),nitrate N,total phosphorus(P),available potassium(K)and the activities of the enzymes urease,acid phosphatase and catalase in soils irrigated with fresh water,wastewater and CMI-treated wastewater under three amount of irrigation water.The results showed that irrigation with both treated and untreated wastewater significantly increased soil total N,total P,and available K,however the treated wastewater showed higher effects on soil enrichment,especially on available K.The activity of soil urease and acid phosphatase reached highest with treated wastewater irrigation,whereas wastewater irrigation increased the activity of catalase obviously.Soil enzyme and nutrient with fresh water irrigation decreased with increasing water amount;the content of soil urease,nitrate-nitrogen,total N and total P in treated wastewater and wastewater irrigation rose with increasing water amount,but the highest activity of acid phosphatase and the lowest activity of catalase were found in medium irrigation water amount.Under the condition of tomato cultivation,total N,nitrate N and total P were closely correlated with soil urease and catalase;there were significant positive correlation among soil urease,catalase,total N,nitrate N and total P;there existed significantly positive correlation between acid phosphatase and all measured soil nutrient indexes.The results suggested that irrigation with CMI-treated wastewater is a security and effective strategy to agricultural land management. | Wang Chunfang Shao Xiaohou Xu Huilian Chang Tingting Wang Weina | 2016 | International Journal of Agricultural and Biological Engineering2016,9,6: | 4 |
| 16 | A viral vector expressing hypoxia-inducible factor 1 alpha inhibits hippocampal neuronal apoptosis显示文摘Hypoxia-inducible factor 1(HIF-1) attenuates amyloid-beta protein neurotoxicity and decreases apoptosis induced by oxidative stress or hypoxia in cortical neurons. In this study, we constructed a recombinant adeno-associated virus(rAAV) vector expressing the human HIF-1α gene(rAAV-HIF-1α), and tested the assumption that rAAV-HIF-1α represses hippocampal neuronal apoptosis induced by amyloid-beta protein. Our results confirmed that rAAV-HIF-1α significantly reduces apoptosis induced by amyloid-beta protein in primary cultured hippocampal neurons. Direct intracerebral rAAV-HIF-1α administration also induced robust and prolonged HIF-1α production in rat hippocampus. Single rAAV-HIF-1α administration resulted in decreased apoptosis of hippocampal neurons in an Alzheimer's disease rat model established by intracerebroventricular injection of aggregated amyloid-beta protein(25–35). Our in vitro and in vivo findings demonstrate that HIF-1 has potential for attenuating hippocampal neuronal apoptosis induced by amyloid-beta protein, and provides experimental support for treatment of neurodegenerative diseases using gene therapy. | Xiqing Chai Weina Kong Lingyun Liu Wenguo Yu Zhenqing Zhang Yimin Sun | 2014 | Neural Regeneration Research2014,9,11: | 4 |

| 18 | Single atom catalytic oxidation mechanism of formaldehyde on Al doped graphene at room temperature显示文摘Formaldehyde(HCHO) is one kind of common indoor toxic pollutant,the catalytic oxidation degradation of formaldehyde at room temperature is desired.In this work,a new single atomic catalyst(SAC),Al doped graphene,for the catalytic oxidation of HCHO molecules was proposed through density function theory(DFT) calculations.It is found that Al atoms can be adsorbed on graphene stably without aggre s sion.Then HCHO can be effectively oxidized into CO2 and H2 O in the presence of O2 molecules on Al doped graphene with a low energy barrier of 0.82 eV and releasing energy of 2.29 eV with the pathway of HCHO→HCOOH→CO→CO2.The oxidation reaction can happen promptly with reaction time τ=56.9 s at the speed control step at room temperature.Therefore,this work proposed a high-performance catalyst Al-doped graphene without any noble metal for HCHO oxidation at ambient temperature,and corresponding oxidation pathway and mechanism are also deeply understood. | Guanlan Liu Jtmhui Zhou Weina Zhao Zhimin Ao Taicheng An | 2020 | Chinese Chemical Letters2020,31,7: | 3 |
| 19 | Human factors quantification via boundary identification of flight performance margin显示文摘A systematic methodology including a computational pilot model and a pattern recognition method is presented to identify the boundary of the flight performance margin for quantifying the human factors. The pilot model is proposed to correlate a set of quantitative human factors which represent the attributes and characteristics of a group of pilots. Three information processing components which are influenced by human factors are modeled: information perception, decision making, and action execution. By treating the human factors as stochastic variables that follow appropriate probability density functions, the effects of human factors on flight performance can be investigated through Monte Carlo(MC) simulation. Kernel density estimation algorithm is selected to find and rank the influential human factors. Subsequently, human factors are quantified through identifying the boundary of the flight performance margin by the k-nearest neighbor(k-NN) classifier. Simulation-based analysis shows that flight performance can be dramatically improved with the quantitative human factors. | Yang Changpeng Yin Tangwen Zhao Weina Huang Dan Fu Shan | 2014 | Chinese Journal of Aeronautics2014,27,4: | 3 |
| 20 | Emerging porous nanosheets:From fundamental synthesis to promising applications显示文摘Metal-organic framework(MOF)nanosheets and covalent organic framework(COF)nanosheets as emerging porous materials nanosheets have captured increasing attention owing to their attractive properties originating from the advantages of large lateral size,ultrathin thickness,tailorable physiochemical environment,flexibility and highly accessible active sites on surface,and the applications of them have been explored in a wide range of fields.Although MOF and COF nanosheets own many similar properties,their applications in various fields show significant differences,probably due to their different compositions and bonding modes.Hence,we summarize the recent progress of MOF and COF nanosheets by comparative analysis on their advantages and limitations in synthesis and applications,providing a more profound and full-scale perspective for researchers or beginners to understand this field.Herein,the categories of preparation methods of MOF and COF nanosheets are firstly discussed,including top-down and bottom-up methods.Secondly,the applications of MOF and COF nanosheets for separation,catalysis,sensing and energy storage are summarized.Finally,based on current achievements,we put forward our personal insights into the challenges and outlooks on the synthesis,characterizations,and promising applications for future research of MOF and COF nanosheets. | Yun Fan Jia Zhang Yu Shen Bing Zheng Weina Zhang Fengwei Huo | 2021 | Nano Research2021,14,1: | 3 |
