| 2 | Alteration of dominant cyanobacteria in different bloom periods caused by abiotic factors and species interactions显示文摘Freshwater cyanobacterial blooms have drawn public attention because they threaten the safety of water resources and human health worldwide.Heavy cyanobacterial blooms outbreak in Lake Taihu in summer annually and vanish in other months.To find out the factors impacting the cyanobacterial blooms,the present study measured the physicochemical parameters of water and investigated the composition of microbial community using the 16S rRNA gene and internal transcribed spacer amplicon sequencing in the months with or without bloom.The most interesting finding is that two major cyanobacteria,Planktothrix and Microcystis,dramatically alternated during a cyanobacterial bloom in 2016,which is less mentioned in previous studies.When the temperature of the water began increasing in July,Planktothrix appeared first and showed as a superior competitor for M.aeruginosa in NO3^−-rich conditions.Microcystis became the dominant genus when the water temperature increased further in August.Laboratory experiments confirmed the influence of temperature and the total dissolved nitrogen(TDN)form on the growth of Planktothrix and Microcystis in a co-culture system.Besides,species interactions between cyanobacteria and non-cyanobacterial microorganisms,especially the prokaryotes,also played a key role in the alteration of Planktothrix and Microcystis.The present study exhibited the alteration of two dominant cyanobacteria in the different bloom periods caused by the temperature,TDN forms as well as the species interactions.These results helped the better understanding of cyanobacterial blooms and the factors which contribute to them. | Zhenyan Zhang Xiaoji Fan WJ.G.M.Peijnenburg Meng Zhang Liwei Sun Yujia Zhai Qi Yu Juan Wu Tao Lu Haifeng Qian | 2021 | Journal of Environmental Sciences2021,33,1: | 2 |

| 4 | Performance evaluation of multi-GNSSs navigation in super synchronous transfer orbit and geostationary earth orbit显示文摘The autonomous navigation of the spacecrafts in High Elliptic Orbit (HEO), Geostationary Earth Orbit (GEO) and Geostationary Transfer Orbit (GTO) based on Global Navigation Satellite System (GNSS) are considered feasible in many studies. With the completion of BeiDou Navigation Satellite System with Global Coverage (BDS-3) in 2020, there are at least 130 satellites providing Position, Navigation, and Timing (PNT) services. In this paper, considering the latest CZ-5(Y3) launch scenario of Shijian-20 GEO spacecraft via Super-Synchronous Transfer Orbit (SSTO) in December 2019, the navigation performance based on the latest BeiDou Navigation Satellite System (BDS), Global Positioning System (GPS), Galileo Navigation Satellite System (Galileo) and GLObal NAvigation Satellite System (GLONASS) satellites in 2020 is evaluated, including the number of visible satellites, carrier to noise ratio, Doppler, and Position Dilution of Precision (PDOP). The simulation results show that the GEO/Inclined Geo-Synchronous Orbit (IGSO) navigation satellites of BDS-3 can effectively increase the number of visible satellites and improve the PDOP in the whole launch process of a typical GEO spacecraft, including SSTO and GEO, especially for the GEO spacecraft on the opposite side of Asia-Pacific region. The navigation performance of high orbit spacecrafts based on multi-GNSSs can be significantly improved by the employment of BDS-3. This provides a feasible solution for autonomous navigation of various high orbit spacecrafts, such as SSTO, MEO, GEO, and even Lunar Transfer Orbit (LTO) for the lunar exploration mission. | Tao Shi Xuebin Zhuang Liwei Xie | 2021 | Satellite Navigation2021,2,1: | 1 |
| 5 | MULTIPARAMETER MEASUREMENT FOR RACEWAY GROOVE OF BEARING BASED ON 3D RECONSTRUCTION WITH DIGITAL STRUCTURED LIGHT显示文摘A fast 3D reconstruction method based on structured light to measure various parameters of theraceway groove is presented. Digital parallel grating stripes distributed with sine density are projected ontothe raceway groove by a DLP projector, and distorting of stripes is happened on the raceway. Simultane-ously, aided by three-step phase-shifting approach, three images covered by different stripes are obtained bya high-resolution CCD camera at the same location, thus a more accuracy local topography can be obtained.And then the bearing is rotated on a high precision computer controlled rotational stage. Three images arealso obtained as the former step at next planned location triggered by the motor. After one cycle, all imagesinformation is combined through the mosaics. As a result, the 3D information of raceway groove can begained. Not only geometric properties but also surface flaws can be extracted by software. A preliminaryhardware system has been built, with which some geometric parameters have been extracted from recon-structed local topography. | He Tao Zhong Ming LiWei Zhong Yuning Shi Tielin | 2005 | Chinese Journal of Mechanical Engineering2005,18,3: | 1 |
| 6 | Moisture stable and ultrahigh-rate Ni/Mn-based sodium-ion battery cathodes via K^(+)decoration显示文摘As one of the most promising cathodes for sodium-ion batteries(SIBs),the layered transition metal oxides have attracted great attentions due to their high specific capacities and facile synthesis.However,their applications are still hindered by the problems of poor moisture stability and sluggish Na^(+)diffusion caused by intrinsic structural Jahn–Teller distortion.Herein,we demonstrate a new approach to settle the above issues through introducing K^(+)into the structures of Ni/Mn-based materials.The physicochemical characterizations reveal that K^(+)induces atomic surface reorganization to form the birnessite-type K_(2)Mn_(4)O_(8).Combining with the phosphate,the mixed coating layer protects the cathodes from moisture and hinders metal dissolution into the electrolyte effectively.Simultaneously,K^(+)substitution at Na site in the bulk structure can not only widen the lattice-spacing for favoring Na^(+)diffusion,but also work as the rivet to restrain the grain crack upon cycling.The as achieved K^(+)-decorated P2-Na_(0.67)Mn_(0.75)Ni_(0.2)5O_(2)(NKMNO@KM/KP)cathodes are tested in both coin cell and pouch cell configurations using Na metal or hard carbon(HC)as anodes.Impressively,the NKMNO@KM/KP||Na half-cell demonstrates a high rate performance of 50 C and outstanding cycling performance of 90.1%capacity retention after 100 cycles at 5 C.Furthermore,the NKMNO@KM/KP||HC fullcell performed a promising energy density of 213.9 Wh·kg^(−1).This performance significantly outperforms most reported state-ofthe-art values.Additionally,by adopting this strategy on O3-NaMn_(0.5)Ni_(0.5)O_(2),we further proved the universality of this method on layered cathodes for SIBs. | Tao Yuan Yuanyuan Sun Siqing Li Haiying Che Qinfeng Zheng Yongjian Ni Yixiao Zhang Jie Zou Xiaoxian Zang Shi-Hao Wei Yuepeng Pang Shuixin Xia Shiyou Zheng Liwei Chen Zi-Feng Ma | 2023 | Nano Research2023,16,5: | 1 |
| 7 | Suppression of LjBAK1-mediated immunity by SymRK promotes rhizobial infection in Lotus japonicus.显示文摘An important question in biology is how organisms can associate with different microbes that pose no threat (commensals), pose a severe threat (pathogens) and those that are beneficial (symbionts). The root nodule symbiosis serves as important model system to address such questions in the context of plant-microbe interactions. It is now generally accepted that rhizobia have the abilities to actively suppress host immune responses during the infection process, analogous to the way in which plant pathogens can evade immune recognition. However, much remains to be elucidated with regard to the mechanisms by which the host recognizes the rhizobia as pathogens and how, subsequently, these pathways are suppressed to allow establishment of the nitrogen fixing symbiosis. In this study, we found that SymRK (Symbiosis Receptor-like Kinase) is required for rhizobial suppression of plant innate immunity in Lotus japonicus. SymRK associates with LjBAK1 (BRASSINOSTEROID INSENSITIVE 1-Associated receptor Kinase 1), a well characterized, positive regulator of plant innate immunity, and directly inhibits LjBAK1 kinase activity. Rhizobial inoculation enhances the association between SymRK and LjBAK1 in planta. LjBAK1 is required to regulate plant innate immunity and plays a negative role in mediating rhizobial infection in L. japonicus. The data indicate that the protein complex of SymRK-LjBAK1 serves as an intersection point between rhizobial symbiotic signaling pathways and innate immunity pathways, which provides an evidence that rhizobia might actively suppress the host's ability to mount a defense response in the legume-rhizobium symbiosis. | Yong Feng Ping Wu Chao Liu Liwei Peng Tao Wang Chao Wang Qian Tan Bixuan Li Yajuan Ou Hui Zhu Songli Yuan Renliang Huang Gary Stacey Zhongming Zhang Yangrong Cao | 2021 | Molecular Plant2021,14,11: | 0 |
| 8 | An antifouling catechol/chitosan-modified polyvinylidene fluoride membrane for sustainable oil-in-water emulsions separation显示文摘Low-pressure membrane filtrations are considered as effective technologies for sustainable oil/water separation.However,conventional membranes usually suffer from severe pore clogging and surface fouling,and thus,novel membranes with superior wettability and antifouling features are urgently required.Herein,we report a facile green approach for the development of an underwater superoleophobic microfiltration membrane via one-step oxidant-induced ultrafast co-deposition of naturally available catechol/chitosan on a porous polyvinylidene fluoride(PVDF)substrate.Membrane morphology and surface chemistry were studied using a series of characterization techniques.The as-prepared membrane retained the original pore structure due to the ultrathin and uniform catechol/chitosan coating.It exhibited ultrahigh pure water permeability and robust chemical stability under harsh pH conditions.Moreover,the catechol/chitosan hydrophilic coating on the membrane surface acting as an energetic barrier for oil droplets could minimize oil adhesion on the surface,which endowed the membrane with remarkable antifouling property and reusability in a cyclic oil-in-water(O/W)emulsion separation.The modified membrane exhibited a competitive flux of~428 L/(m^(2)·h·bar)after three filtration cycles,which was 70%higher than that of the pristine PVDF membrane.These results suggest that the novel underwatersuperoleophobic membrane can potentially be used for sustainable O/W emulsions separation,and the proposed green facile modification approach can also be applied to other water-remediation materials considering its low cost and simplicity. | Shanshan Zhao Zhu Tao Liwei Chen Muqiao Han Bin Zhao Xuelin Tian Liang Wang Fangang Meng | 2021 | Frontiers of Environmental Science & Engineering2021,15,4: | 0 |
| 9 | Regional Effect of APS-sEPS on Intestinal Structure and Mucosal Immunity in Mice显示文摘[Objectives]The aim of this study was to investigate the effects of APS-sEPS(a polysaccharide compound of Astragalus polysaccharides and sulfated Epimedium polysaccharide)on intestinal mucosal immunity and structural morphology.[Methods]Firstly,the diarrhea model was established using the optimal dose of magnesium sulfate in mice.Then,the diarrhea mice were randomly divided into three groups and given either physiological saline(diarrhea model group)or injected with APS-sEPS or APS.The normal mice were selected as a control group.After administration,the duodenum,jejunum and ileum were processed microtome section,and observed for describing the small intestine morphology,villus height and crypt depth.The tissue homogenates of the duodenum,jejunum and ileum were gathered to detect the changes of sIgA,IL-4 and IL-10.[Results]The results indicated that APS-sEPS could effectively relieve diarrhea in mice.In the APS-sEPS group,the villus heights of duodenum,jejunum and ileum were increased and the depth of crypt was reduced.The contents of IL-4,IL-10 and sIgA in jejunum and ileum in APS-sEPS group were significantly higher than that in the control group(P<0.05).[Conclusions]These results indicated that APS-sEPS promoted the recovery of intestinal morphological structure and enhanced the mucosa immunity of the small intestine. | Lei CHENG Qing JIN Rong CHEN Wei ZHANG Niandong YAN Tao XIONG Xiaona ZHAO Liwei GUO | 2020 | Agricultural Biotechnology2020,9,6: | 0 |

| 12 | A Cloud Framework for High Spatial Resolution Soil Moisture Mapping from Radar and Optical Satellite Imageries显示文摘Soil moisture plays an important role in crop yield estimation,irrigation management,etc.Remote sensing technology has potential for large-scale and high spatial soil moisture mapping.However,offline remote sensing data processing is time-consuming and resource-intensive,and significantly hampers the efficiency and timeliness of soil moisture mapping.Due to the high-speed computing capabilities of remote sensing cloud platforms,a High Spatial Resolution Soil Moisture Estimation Framework(HSRSMEF)based on the Google Earth Engine(GEE)platform was developed in this study.The functions of the HSRSMEF include research area and input datasets customization,radar speckle noise filtering,optical-radar image spatio-temporal matching,soil moisture retrieving,soil moisture visualization and exporting.This paper tested the performance of HSRSMEF by combining Sentinel-1,Sentinel-2 images and insitu soil moisture data in the central farmland area of Jilin Province,China.Reconstructed Normalized Difference Vegetation Index(NDVI)based on the Savitzky-Golay algorithm conforms to the crop growth cycle,and its correlation with the original NDVI is about 0.99(P<0.001).The soil moisture accuracy of the random forest model(R 2=0.942,RMSE=0.013 m3/m3)is better than that of the water cloud model(R 2=0.334,RMSE=0.091 m3/m3).HSRSMEF transfers time-consuming offline operations to cloud computing platforms,achieving rapid and simplified high spatial resolution soil moisture mapping. | GUO Tianhao ZHENG Jia WANG Chunmei TAO Zui ZHENG Xingming WANG Qi LI Lei FENG Zhuangzhuang WANG Xigang LI Xinbiao KE Liwei | 2023 | Chinese Geographical Science2023,33,4: | 0 |
| 13 | Bacterial biogeography in China and its association to land use and soil organic carbon显示文摘●6102 high-quality sequencing results of soil bacterial samples were re-analyzed.●The type of land use was the principal driver of bacterial richness and diversity.●SOC content is positively correlated with key bacteria and total nitrogen content.Soil organic carbon(SOC)is the largest pool of carbon in terrestrial ecosystems and plays a crucial role in regulating atmospheric CO_(2) concentrations.Identifying the essential relationship between soil bacterial communities and SOC concentration is complicated because of many factors,one of which is geography.We systematically re-analyzed 6102 high-quality bacterial samples in China to delineate the bacterial biogeographic distribution of bacterial communities and identify key species associated with SOC concentration at the continental scale.The type of land use was the principal driver of bacterial richness and diversity,and we used machine learning to calculate its influence on microbial composition and their co-occurrence relationship with SOC concentration.Cultivated land was much more complex than forest,grassland,wetland and wasteland,with high SOC concentrations tending to enrich bacteria such as Rubrobacter,Terrimonas and Sphingomona.SOC concentration was positively correlated with the amounts of soil total nitrogen and key bacteria Xanthobacteraceae,Streptomyces and Acidobacteria but was negatively correlated with soil pH,total phosphorus and Micrococcaceae.Our study combined the SOC pool with bacteria and indicated that specific bacteria may be key factors affecting SOC concentration,forcing us to think about microbial communities associated with climate change in a new way. | Tao Lu Nuohan Xu Chaotang Lei Qi Zhang Zhenyan Zhang Liwei Sun Feng He Ning-Yi Zhou Josep Peñuelas Yong-Guan Zhu Haifeng Qian | 2023 | Soil Ecology Letters2023,5,4: | 0 |
| 14 | Regulation of rose petal dehydration tolerance and senescence by RhNAP transcription factor via the modulation of cytokinin catabolism显示文摘Petals and leaves share common evolutionary origins but have different phenotypic characteristics,such as the absence of stomata in the petals of most angiosperm species.Plant NAC transcription factor,NAP,is involved in ABA responses and regulates senescence-associated genes,and especially those that affect stomatal movement.However,the regulatory mechanisms and significance of NAP action in senescing astomatous petals is unclear.A major limiting factor is failure of flower opening and accelerated senescence.Our goal is to understand the finely regulatory mechanism of dehydration tolerance and aging in rose flowers.We functionally characterized RhNAP,an AtNAP-like transcription factor gene that is induced by dehydration and aging in astomatous rose petals.Cytokinins(CKs)are known to delay petal senescence and we found that a cytokinin oxidase/dehydrogenase gene 6(RhCKX6)shares similar expression patterns with RhNAP.Silencing of RhNAP or RhCKX6 expression in rose petals by virus induced gene silencing markedly reduced petal dehydration tolerance and delayed petal senescence.Endogenous CK levels in RhNAP-or RhCKX6-silenced petals were significantly higher than those of the control.Moreover,RhCKX6 expression was reduced in RhNAP-silenced petals.This suggests that the expression of RhCKX6 is regulated by RhNAP.Yeast one-hybrid experiments and electrophoresis mobility shift assays showed that RhNAP binds to the RhCKX6 promoter in heterologous in vivo system and in vitro,respectively.Furthermore,the expression of putative signal transduction and downstream genes of ABA-signaling pathways were also reduced due to the repression of PP2C homolog genes by RhNAP in rose petals.Taken together,our study indicates that the RhNAP/RhCKX6 interaction represents a regulatory step enhancing dehydration tolerance in young rose petals and accelerating senescence in mature petals in a stomata-independent manner. | Jing Zou Peitao Lü Liwei Jiang Kun Liu Tao Zhang Jin Chen Yi Yao Yusen Cui Junping Gao Changqing Zhang | 2021 | Molecular Horticulture2021,1,1: | 0 |
| 15 | 青藏高寒草甸生态系统碳交换年际变异主要受生物效应影响显示文摘位于西藏的高寒草甸生态系统具有敏感脆弱的特点,在全球气候变化背景下,其碳汇功能的变化受到了广泛的关注。因此,本研究旨在明确高寒草甸碳通量的年际变异特征,并进一步量化各驱动因素对碳通量变异的贡献。本研究基于7年(2012-2018)的碳通量与气象因子和生物因子数据,采用一组查表法(look-uptables,,LUTs)对高寒草甸碳通量的年际变异来源进行了拆分和量化,并进一步利用线性扰动分析法量化了各个关键因子对碳通量变异的贡献。2012-2018年,高寒草甸生态系统净生产力(net ecosystem productivity,NEP)、总初级生产力(gross primary productivity,GPP)和生态系统呼吸(ecosystem respiration,Re)多年平均值分别为3.31±26.90、210.18±48.35和206.88±28.45gCm^(-2)y^(-1),表现出了较大的年际变异。本研究通过区分和量化气象因子和生物因子对碳通量年际变异的贡献,发现了生物因子对年际变异的主控作用。此外,发现了气象因子和生物因子之间的负反馈作用。在气象因子中,只有土壤水分对年际变异的贡献相对较大,并在气象因子和生物因子的相互作用中发挥着调节作用。这些结果表明,在气候变化背景下,若要准确估算碳通量,需考虑生物因子的作用。 | Mingjie Xu Yi Sun Tao Zhang Yangjian Zhang Juntao Zhu Yongtao He Liwei Wang Guirui Yu | 2022 | Journal of Plant Ecology2022,15,5: | 0 |
| 16 | Polymerization of pyrrole induced by pillar[5]arene functionalized graphene for supercapacitor electrode显示文摘Conducting polymer is an important electrode material for supercapacitors because of its high initial specific capacitance.Herein,a novel nanocomposite composed of polypyrrole(PPy)film homogeneously immobilized on the pillar[5]arene functionalized reduced graphene oxide nanosheets(RGO-HP5 A-PPy)was successfully prepared.RGO-HP5 A induced pyrrole to polymerize on the graphene surface and the specific capacitance loss caused by PPy agglomeration was avoided.Noticeably,the specific capacitance of RGOHP5 A-PPy was up to 495 F/g at 1 A/g.Compared with pure PPy(319 F/g),the specific capacitance was increased by 55%.The specific capacitance retention of the assembled symmetric supercapacitor reached76%after 10,000 cycles at 5 A/g.This study gave full play to the advantages of pillar[5]arene,graphene and PPy,and was expected to promote the development of supramolecular functionalized composites in energy storage. | Fang Guo Junqiang Guo Zhiqiang Zheng Tao Xia Aadil Nabi Chishti Liwei Lin Wang Zhang Guowang Diao | 2022 | Chinese Chemical Letters2022,33,11: | 0 |
| 17 | Multi-Antenna Jammer Assisted Covert Communications in Data Collected IoT with NOMA显示文摘In this paper,we investigate covert communications in data collected IoT with NOMA,where the paired sensor nodes S_(m) and S_(n) transmit covert messages to a legitimate receiver(Bob)in the presence of a Warden(Willie).To confuse the detection at Willie,an extra multi-antenna friendly jammer(Jammer)has been employed to transmit artificial noise(AN)with random power.Based on the CSI of Willie is available or not at Jammer,three AN transmission schemes,including null-space artificial noise(NAN),transmit antenna selection(TAS),and zeroforcing beamforming(ZFB),are proposed.Furthermore,the closed-form expressions of expected minimum detection error probability(EMDEP)and joint connection outage probability(JCOP)are derived to measure covertness and reliability,respectively.Finally,the maximum effective covert rate(ECR)is obtained with a given covertness constraint.The numerical results show that ZFB scheme has the best maximum ECR in the case of the number of antennas satisfies N>2,and the same maximum ECR can be achieved in ZFB and NAN schemes with N=2.Moreover,TAS scheme also can improve the maximum ECR compared with the benchmark scheme(i.e.,signal-antenna jammer).In addition,a proper NOMA node pairing can further improve the maximum ECR. | Liwei Tao Weiwei Yang Xingbo Lu Ruiqian Ma Ling Yang Yi Song | 2023 | China Communications2023,20,5: | 0 |
