| 1 | The wide-area difference system for the regional satellite navigation system of COMPASS显示文摘The regional satellite navigation system of COMPASS (Phase I) provides both open services and authorized services. Authorized services offer differential corrections and integrity information to users to support higher positioning, navigation and timing precision. Experimenting with real data, positioning accuracy is estimated with a 3GEO/4IGSO COMPASS constellation. The results show that with dual-frequency and single-frequency pseudo-range measurements, the positioning errors are respectively 8 and 10 m (RMS) for open service users, while for authorized users, the errors are 4 and 5 m (RMS), respectively. The COMPASS constellation geometry may cause large error to occur in the height component by 7-9 m for dualor single-frequency users, which can be effectively reduced with the differential corrections supplied by the authorized services. Multipath errors are identified and corrected for COMPASS, resulting in 25% positioning accuracy improvement for dual-frequency users and 10% improvement for single-frequency users. | CAO YueLing HU XiaoGong WU Bin ZHOU ShanShi LIU Li SU RanRan CHANG ZhiQiao HE Feng ZHOU JianHua | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，7： | 21 |

| 3 | Analysis of RDSS positioning accuracy based on RNSS wide area differential technique显示文摘The BeiDou Navigation Satellite System(BDS) provides Radio Navigation Service System(RNSS) as well as Radio Determination Service System(RDSS).RDSS users can obtain positioning by responding the Master Control Center(MCC) inquiries to signal transmitted via GEO satellite transponder.The positioning result can be calculated with elevation constraint by MCC.The primary error sources affecting the RDSS positioning accuracy are the RDSS signal transceiver delay,atmospheric trans-mission delay and GEO satellite position error.During GEO orbit maneuver,poor orbit forecast accuracy significantly impacts RDSS services.A real-time 3-D orbital correction method based on wide-area differential technique is raised to correct the orbital error.Results from the observation shows that the method can successfully improve positioning precision during orbital maneuver,independent from the RDSS reference station.This improvement can reach 50% in maximum.Accurate calibration of the RDSS signal transceiver delay precision and digital elevation map may have a critical role in high precise RDSS positioning services. | XING Nan SU RanRan ZHOU JianHua HU XiaoGong GONG XiuQiang LIU Li HE Feng GUO Rui REN Hui HU GuangMing ZHANG Lei | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，10： | 6 |
| 4 | A novel imidazoline derivative as corrosion inhibitor for P110 carbon steel in hydrochloric acid environment显示文摘novel imidazoline derivative,2-methyl-4-phenyl-1-tosyl-4,5-dihydro-1H-imidazole(IMI),was prepared and investigated as corrosion inhibitor for P110 carbon steel in 1.0 M HCl solution by weight loss measurements,potentiodynamic polarization and electrochemical impedance spectroscopy(EIS)tests.The inhibition efficiency increased with the rising concentration of IMI inhibitor.The test results and fitting data indicated that the IMI behaved as a mixed-type inhibitor and obeys the Langmuir adsorption isotherm.Scanning electron microscopy(SEM)was carried out to investigate the surface of carbon steel specimens,showing great protection from aggressive solution.Finally,inhibition mechanism of IMI on metal surface was further discussed. | Lei Zhang Yi He Yanqiu Zhou Ranran Yang Qiangbin Yang Dayong Qing Qianhe Niu | 2015 | Petroleum2015，1，3： | 5 |

| 6 | Solvent-and metal-directed lanthanide-organic frameworks based on pamoic acid:observation of slow magnetization relaxation,magnetocaloric effect and luminescent sensing显示文摘Two types of lanthanide coordination polymers, namely, [Ln(PA)(NO_3)(DMA)_3]_n(Ln=Gd(1), Dy(2), Eu(3), Tb(4))(type I), and {[Ln_2(PA)_3(DMF)_4]·2DMF}(Ln=Eu(5), Tb(6))(type II)(PA=Pamoic acid, DMA=dimethylacetamide,DMF=N,N-dimethylformamide), have been synthesized by the reaction of Ln(NO_3)_3·6H_2O with pamoic acid through layer diffusion method. These complexes were characterized by single crystal X-ray diffraction, infrared spectroscopy(IR),thermogravimetric analysis(TGA), fluorescence and magnetic measurements. Solvents and lanthanide atoms in the reaction play an important role in controlling different structures. Type I demonstrated 1-D linear chain structure connected by Ln atoms and PA ligands. Type II exhibited non-interpenetrating 3-D 6-connected 4_36^(12) nets based on binuclear [Ln_2(CO_2)_6(DMF)_4] cores.Magnetic properties of complexes 1–4 were investigated in details. Complex 1 shows significant magnetocaloric effect with–ΔS_m=20.37 J kg^(–1) K^(–1) at 3.0 K and 7 T. Complex 2 exhibits slow relaxation of the magnetization. Complexes 3–6 exhibit both ligand- and metal-centered fluorescent properties. Complex 6 demonstrates fluorescent sensing of DMF and Cu^(2+) ion. | Suna Wang Ranran Ma Zhiwei Chen Yunwu Li Tingting Cao Changhui Zhou Junfeng Bai | 2016 | Science China Chemistry2016，59，8： | 3 |
| 7 | Stoichiometric Conversion of Maltose for Biomanufacturing by In Vitro Synthetic Enzymatic Biosystems显示文摘Maltose is a natural α-(1,4)-linked disaccharide with wide applications in food industries and microbial fermentation. However,maltose has scarcely been used for in vitro biosynthesis, possibly because its phosphorylation by maltose phosphorylase (MP)yields β-glucose 1-phosphate (β-G1P) that cannot be utilized by α-phosphoglucomutase (α-PGM) commonly found in in vitrosynthetic enzymatic biosystems previously constructed by our group. Herein, we designed an in vitro synthetic enzymaticreaction module comprised of MP, β-phosphoglucomutase (β-PGM), and polyphosphate glucokinase (PPGK) for thestoichiometric conversion of each maltose molecule to two glucose 6-phosphate (G6P) molecules. Based on this syntheticmodule, we further constructed two in vitro synthetic biosystems to produce bioelectricity and fructose 1,6-diphosphate (FDP),respectively. The 14-enzyme biobattery achieved a Faraday efficiency of 96.4% and a maximal power density of 0.6mW/cm^(2),whereas the 5-enzyme in vitro FDP-producing biosystem yielded 187.0mM FDP from 50 g/L (139mM) maltose by adopting afed-batch substrate feeding strategy. Our study not only suggests new application scenarios for maltose but also provides novelstrategies for the high-efficient production of bioelectricity and value-added biochemicals. | Guowei Li Xinlei Wei Ranran Wu Wei Zhou Yunjie Li Zhiguang Zhu Chun You | 2022 | BioDesign Research2022，，1： | 2 |
| 8 | O-linked N-acetylglucosamine transferase(OGT) is overexpressed and promotes O-linked protein glycosylation in esophageal squamous cell carcinoma显示文摘The aim of this present study was to explore the expression and clinical significance of O-linked N-acetylglucosamine(O-GlcNAc) transferase(OGT) and enzymatic O-linked glycosylation(O-GlcNAcation) through the addition of O-linked-β-N-acetylglucosamine in esophageal squamous cell carcinoma.OGT expression and O-GlcNAcation in 40 samples from patients with esophageal squamous cell carcinoma was detected by immunohistochemical staining with anti-OGT antib ody and O-GlcNAc-specific antibody RL 2,respectively.The relationship between pathological and clinical factors of patients was analyzed.We found that the expression of OGT was higher in esophageal squamous cell carcinoma samples compared to the normal tissues.RL 2 antibody level was positively correlated with OGT expression,and the metastasis of lymph node,which means the level of O-GlcNAcation was high and related to the metastasis of lymph node in esophageal squamous cell carcinoma.In conclusion,OGT activation is the main reason for promoting the level of O-GlcNAcation in esophageal squamous cell carcinoma.O-GlcNAcylation may play an important role in esophageal squamous cell carcinoma. | Zhe Qiao Chengxue Dang Bin Zhou Shaomin Li Wei Zhang Jiantao Jiang Jin Zhang Ranran Kong Yuefeng Ma | 2012 | The Journal of Biomedical Research2012，26，4： | 2 |
| 9 | Biodegradation of 2-ethylhexyl-4-methoxycinnamate in river sediments and its impact on microbial communities显示文摘Numerous studies have evaluated the toxicity and endocrine disrupting properties of organic UV filters for aquatic organisms,but little is known about their biodegradation in river sediments and their impact on microorganisms.We have set up the sterile and microbiological systems in the laboratory,adding 2-ethylhexyl-4-methoxycinnamate(EHMC),one of organic UV filters included in the list of high yield chemicals,at concentrations of 2,20 and 200μg/L,and characterized the microbial community composition and diversity in sediments.Monitoring of EHMC degradation within 30 days revealed that the half-life in the microbial system(3.49 days)was much shorter than that in the sterile system(7.55 days).Two potential degradation products,4-mercaptobenzoic acid and 3-methoxyphenol were identified in the microbial system.Furthermore,high-throughput 16s and 18s rRNA gene sequencing showed that Proteobacteria dominated the sediment bacterial assemblages followed by Chloroflexi,Acidobacteria,Bacteroidetes and Nitrospirae;Eukaryota_uncultured fungus dominated the sediment fungal assemblages.Correlation analysis demonstrated that two bacterium genera(Anaerolineaceae_uncultured and Burkholderiaceae_uncultured)were significantly correlated with the biodegradation of EHMC.These results illustrate the biodegradability of EHMC in river sediments and its potential impact on microbial communities,which can provide useful information for eliminating the pollution of organic UV filters in natural river systems and assessing their potential ecological risks. | Peng Zhang Guanghua Lu Jianchao Liu Zhenhua Yan Huike Dong Ranran Zhou | 2021 | Journal of Environmental Sciences2021，33，6： | 1 |

| 11 | A chromosome-level genome assembly provides insights into Cornus wilsoniana evolution, oil biosynthesis, and floral bud development显示文摘Cornus wilsoniana W.is a woody oil plant with high oil content and strong hypolipidemic effects,making it a valuable species for medicinal,landscaping,and ecological purposes in China.To advance genetic research on this species,we employed PacBio together with Hi-C data to create a draft genome assembly for C.wilsoniana.Based on an 11-chromosome anchored chromosome-level assembly,the estimated genome size was determined to be 843.51 Mb.The N50 contig size and N50 scaffold size were calculated to be 4.49 and 78.00 Mb,respectively.Furthermore,30474 protein-coding genes were annotated.Comparative genomics analysis revealed that C.wilsoniana diverged from its closest species∼12.46 million years ago(Mya).Furthermore,the divergence between Cornaceae and Nyssaceae occurred>62.22 Mya.We also found evidence of whole-genome duplication events and whole-genome triplicationγ,occurring at∼44.90 and 115.86 Mya.We further inferred the origins of chromosomes,which sheds light on the complex evolutionary history of the karyotype of C.wilsoniana.Through transcriptional and metabolic analysis,we identified two FAD2 homologous genes that may play a crucial role in controlling the oleic to linoleic acid ratio.We further investigated the correlation between metabolites and genes and identified 33 MADS-TF homologous genes that may affect f lower morphology in C.wilsoniana.Overall,this study lays the groundwork for future research aimed at identifying the genetic basis of crucial traits in C.wilsoniana. | Zhenxiang He Haoyu Chao Xinkai Zhou Qingyang Ni Yueming Hu Ranran Yu Minghuai Wang Changzhu Li Jingzhen Chen Yunzhu Chen Yong Chen Chunyi Cui Liangbo Zhang Ming Chen Dijun Chen | 2023 | Horticulture Research2023，10，11： | 0 |

| 13 | Lithographic printing inspired in-situ transfer of MXene-based films with localized topo-electro tunability for high-performance flexible pressure sensors显示文摘MXene-based films have been intensively explored for construction of piezoresistive flexible pressure sensors owing to their excellent mechanical and electrical properties.High pressure sensitivity relies on pre-molding a flexible substrate,or regulating the micromorphology of MXene sheets,to obtain a micro-structured surface.However,the two avenues usually require complicated and time-consuming microfabrication or wet chemical processing,and are limited to non-adjustable topographicelectrical(topo-electro)properties.Herein,we propose a lithographic printing inspired in-situ transfer(LIPIT)strategy to fabricate MXene-ink films(MIFs).In LIPIT,MIFs not only inherit ridge-and-valley microstructure from paper substrate,but also achieve localized topo-electro tunability by programming ink-writing patterns and cycles.The MIF-based flexible pressure sensor with periodical topo-electro gradient exhibits remarkably boosted sensitivity in a wide sensing range(low detection limit of 0.29 Pa and working range of 100 kPa).The MIF sensor demonstrates versatile applicability in both subtle and vigorous pressuresensing fields,ranging from pulse wave extraction and machine learning-assisted surface texture recognition to piano-training glove(PT-glove)for piano learning.The LIPIT is quick,low-cost,and compatible with free ink/substrate combinations,which promises a versatile toolbox for designing functional MXene films with tailored morphological-mechanical-electrical properties for extended application scenarios. | Qiuyang Yan Yi Zhou Yin Cheng Liangjing Shi Ranran Wang Lian Gao Jing Sun | 2023 | Nano Research2023，16，11： | 0 |
| 14 | Systematic annotation of conservation states provides insights into regulatory regions in rice显示文摘Plant genomes contain a large fraction of noncoding sequences.The discovery and annotation of conserved noncoding sequences(CNSs)in plants is an ongoing challenge.Here we report the application of comparative genomics to systematically identify CNSs in 50 well-annotated Gramineae genomes using rice(Oryza sativa)as the reference.We conduct multiple-way whole-genome alignments to the rice genome.The rice genome is annotated as 20 conservation states(CSs)at single-nucleotide resolution using a multivariate hidden Markov model(Cons HMM)based on the multiple-genome alignments.Different states show distinct enrichments for various genomic features,and the conservation scores of CSs are highly correlated with the level of associated chromatin accessibility.We find that at least 33.5%of the rice genome is highly under selection,with more than 70%of the sequence lying outside of coding regions.A catalog of 855,366 regulatory CNSs is generated,and they significantly overlapped with putative active regulatory elements such as promoters,enhancers,and transcription factor binding sites.Collectively,our study provides a resource for elucidating functional noncoding regions of the rice genome and an evolutionary aspect of regulatory sequences in higher plants. | Xinkai Zhou Tao Zhu Wen Fang Ranran Yu Zhaohui He Dijun Chen | 2022 | Journal of Genetics and Genomics2022，49，12： | 0 |
| 15 | MICROBIAL NECROMASS WITHIN AGGREGATES STABILIZES PHYSICALLY-PROTECTED C RESPONSE TO CROPLAND MANAGEMENT显示文摘The interactions of soil microorganisms and structure regulate the degradation and stabilization processes of soil organic carbon(SOC). Microbial necromass is a persistent component of SOC, and its magnitude of accumulation dependent on management and aggregate sizes. A meta-analysis of 121 paired measurements was conducted to evaluate the management effects on contributions of microbial necromass to SOC depending on aggregate fractions. Results showed that the contribution of fungal necromass to SOC increased with aggregate sizes, while bacterial necromass had a higher proportion in silt and clay. Cropland management increased total and fungal necromass in large macroaggregates(47.1% and 45.6%), small macroaggregates(44.0% and 44.2%), and microaggregates(38.9% and 37.6%).Cropland management increased bacterial necromass independent of aggregate fraction sizes. Greater fungal necromass was increased in macroaggregates in response to manure(26.6% to 28.5%) and no or reduced tillage(68.0% to 73.5%). Cover crops increased bacterial necromass by 25.1%in small macroaggregates. Stimulation of microbial necromass was proportional to the increases of SOC within soil aggregates, and the correlation was higher in macroaggregates. Increasing microbial necromass accumulation in macroaggregates can, therefore, be considered as a central component of management strategies that aim to accelerate C sequestration in agricultural soils. | Ranran ZHOU Jing TIAN Zhengling CUI Fusuo ZHANG | 2023 | Frontiers of Agricultural Science and Engineering2023，10，2： | 0 |
| 16 | Enhancement and recovery of photoluminescence and stability by multifunctional etching ligands treatment for perovskite nanocrystals显示文摘Perovskite nanocrystals(PNCs)have recently become promising optoelectronic materials due to their excellent photophysical properties.However,the highly dynamic binding state between ligands and the surface of PNCs has severely restricted their luminescent properties and stabilities.In this work,1,3-bisbenzyl-2-oxoimidazolidine-4,5-dicarboxylic acid(cycle acid,CA)is introduced as both an etchant and a ligand upon post-synthetic surface treatment of PNCs.By removing the imperfect octahedrons[Pb X_(6)]^(4-)and passivating the surface defects synergistically,this treatment improves photoluminescence quantum yields from 76%to 95%and enhances the stability of PNCs against polar solvent,moisture,heat,and illumination.Meanwhile,CA can effectively and instantly recover the luminescence emission for aged PNCs.As a result,the CA-Cs Pb Br_(3)PNCs and CA-Cs Pb IxBr_(3-x)PNCs are applied as color-converting layers on a blue LED chip for warm white light-emitting diodes(WLEDs)with a color coordinate of(0.41,0.40).Importantly,the CA-based WLED device exhibits superior stability in operational conditions. | Yang Zhao Haipeng Zeng Xueqing Cai Yingshan Zhou Yangming Jiang Xin Zheng Lin Li Shujing Zhang Long Luo Weixi Li Xiaoru Zhang Ranran Liu Wenxi Liang Rui Guo Xiong Li | 2023 | Journal of Energy Chemistry2023，，1： | 0 |
| 17 | Screening and identification of HLA-A2-restricted neoepitopes for immunotherapy of non-microsatellite instability-high colorectal cancer显示文摘Colorectal cancer has one of the highest mortality rates among malignant tumors,and most patients with non-microsatellite instability-high (MSI-H) colorectal cancer do not benefit from targeted therapy or immune checkpoint inhibitors.Identification of immunogenic neoantigens is a promising strategy for inducing specific antitumor T cells for cancer immunotherapy.Here,we screened potential high-frequency neoepitopes from non-MSI-H colorectal cancer and tested their abilities to induce tumorspecific cytotoxic T cell responses.Three HLA-A2-restricted neoepitopes (P31,P50,and P52) were immunogenic and could induce cytotoxic T lymphocytes in peripheral blood mononuclear cells from healthy donors and colorectal cancer patients.Cytotoxic T lymphocytes induced in HLA-A2.1/K^(b) transgenic mice could recognize and lyse mutant neoepitope-transfected HLA-A2^(+) cancer cells.Adoptive transfer of cytotoxic T lymphocytes induced by the peptide pool of these three neoepitopes effectively inhibited tumor growth and increased the therapeutic effects of anti-PD-1 antibody.These results revealed the potential of high-frequency mutation-specific peptide-based immunotherapy as a personalized treatment approach for patients with non-MSI-H colorectal cancer.The combination of adoptive T cell therapy based on these neoepitopes with immune checkpoint inhibitors,such as anti-PD-1,could provide a promising treatment strategy for non-MSI-H colorectal cancer. | Ranran Shi Yubing Li Ling Ran Yu Dong Xiuman Zhou Jingwen Tang Lu Han Mingshuang Wang Liwei Pang Yuanming Qi Yahong Wu Yanfeng Gao | 2022 | Science China(Life Sciences)2022，65，3： | 0 |
| 18 | Inter-satellite link augmented BeiDou-3 orbit determination for precise point positioning显示文摘Precise Point Positioning(PPP) requires precise products, including high-accuracy satellite orbit and clock parameters. It is impossible to obtain an orbit solution that is sufficiently accurate for PPP services with a regional tracking network;therefore, satellite orbits are usually estimated by a global tracking network with a large number of ground stations. However, it is expensive to build globally distributed stations. Fortunately, BeiDou-3 satellites carry an InterSatellite Link(ISL) payload, which can track the whole arc of the BeiDou-3 satellites and enhance the orbit determination accuracy with regional ground stations. In this contribution, a novel orbit determination strategy for BeiDou-3 PPP is proposed, in which the BeiDou-3 satellite orbits are enhanced by the ISL. First, the generation of precise satellite products is demonstrated in detail.In addition, the products are assessed by Satellite Laser Ranging(SLR) residuals and overlap comparisons. Moreover, the products are used for receivers in China's Mainland to carry out the static and kinematic modes to research the PPP performance of Bei Dou-3’s 3IGSO/24MEO constellation.The SLR validations of the satellite orbits demonstrate an accuracy better than 0.1 m in the radial component, and the orbit overlap comparisons show accuracies of 0.016 m in the radial component,0.088 m in the along-track component and 0.087 m in the cross-track component. The Standard Deviation(STD) in the differences in overlapping arcs for the estimated satellite clocks is approximately 0.10 ns. The static PPP results demonstrate that the error in both the horizontal and vertical components is smaller than 10 cm after 30 minutes of convergence. After 24 hours of convergence,the errors are 0.70 cm, 0.63 cm and 1.99 cm for the north, east and up components, respectively.The kinematic PPP experiment illustrates that the Root Mean Square(RMS) position errors in the north, east and up components are approximately 3.23 cm, 5.27 cm and 8.64 cm, respectively,after convergence. The obtainable positioning and convergence performances are comparable to those using products generated by global tracking networks. | Liqian ZHAO Xiaogong HU Chengpan TANG Shanshi ZHOU Yueling CAO Qianxin WANG Ranran SU | 2022 | Chinese Journal of Aeronautics2022，35，4： | 0 |
| 19 | Metal halide perovskite nanocrystals with enhanced photoluminescence and stability toward anti-counterfeiting highperformance flexible fibers显示文摘As a new type of light-collecting and luminescent material,all-inorganic cesium lead halide CsPbX_(3)(X=Cl,Br,I)perovskite nanocrystals(NCs)are expected to have a wide range of applications in the fields of photovoltaics,optoelectronics,and fluorescence anti-counterfeiting,etc.Therefore,improving the fluorescence performance and stability of CsPbX_(3)perovskite NCs to prompt their applications would promise both fundamental and practical significance for in-depth research in the field of halide perovskites.In this paper,we developed a modification strategy to introduce a halogen source,zinc bromide(ZnBr_(2))in hexane,to CsPbX_(3)perovskite that can be conducted under atmospheric conditions with reduced reaction cost and easier operation.The first work in this paper was to apply the modification strategy to CsPbI_(3)nanowires(NWs).Compared with the untreated NWs,the ZnBr_(2)/hexane modified CsPbI_(3)NWs exhibited better fluorescence properties.Subsequently,based on the study of perovskite NWs,we investigated perovskite nanocrystal-CsPbI_(3)nanorods(NRs)with different morphologies and sizes.It was found that the luminescence properties of nanorods(NRs)were superior.Later,we infiltrated the modified NRs into the aramid/polyphenylene sulfide(ACFs/PPS)composite paper yielded from our previous work to study its fluorescence performance for anti-counterfeiting.Their luminescence properties under ultraviolet light irradiation enable better performance in fluorescence anti-counterfeiting.The ZnBr_(2)/hexane modification strategy and the applications studied in this work will expand the scope of perovskite research,laying the foundation for the applications of fluorescent anti-counterfeiting,nano-photoelectric devices,and fluorescent composite materials. | Ranran Zhou Chi-An Cheng Xuyi Wang Kun Nie Jing Wu Mengyun Wu Xiuqiang Duan Ziyao Hu Injamam Ul Huq Hua Wang Luoxin Wang Lefu Mei Haikun Liu Xiaoxue Ma | 2023 | Nano Research2023，16，2： | 0 |
| 20 | Synthesis and Characterization of 4,4′-Dibromoazobenzene显示文摘Azobenzene molecules show excellent application potential in many fields due to their photoisomerization properties.Azobenzene molecules will gradually change from trans-structure to cis-structure under the irradiation of UV.In this paper,we have synthesized 4,4'-dibromoazobenzene molecules and characterized their photoisomerization properties.We found that with the extension of UV time,the trans absorption peak at 343 nm decreased significantly,while the cis absorption peak at 435 nm showed an upward trend.Furthermore,photoisomerization of azobenzene is not a first-order reaction. | Ranran Zhen Wei Lu Yun Zhou Minzhen Feng Ya Wang | 2019 | Organic Polymer Material Research2019，1，2： | 0 |
