| 1 | MIMO free space optical communication based on orthogonal space time block code显示文摘An appropriate coding method that can reduce the error rate of communication system is especially important to the free space optical communication. STBC (space-time block code) is an orthogonal encoding method integrating space domain and time domain. The technology can combat fading effectively and improve error rate performance. In this paper, first, an STBC fit for optical communication with intensity modulation and direct detection (IM/DD) is proposed by combining the orthogonality of the Alamouti space-time code and the QPPM modulation. Then, the error rate performance of the system is analyzed under four cases: with or without channel fading, with or without background radiation. At last, this scheme is confirmed by Monte Carlo approach. It is shown that this method not only realizes the full speed rate transmission, and can improve the error rate performance of the system effectively, but also overcomes the scintillation effect exerted by atmosphere turbulence. When the symbol error probability (SEP) is 2×10-3, according to the 1× 1 system, the sending power of the 2×1 system is nearly reduced by 3.5 dBJ, and the 2×2 system is nearly reduced by 9 dBJ. | WANG HuiQin KE XiZheng ZHAO Li | 2009 | Science in China(Series F)2009，52，8： | 7 |
| 2 | Delay-dependent Robust Stability Analysis of Power Systems with PID Controller显示文摘This study examines the robust stability of a power system,which is based on proportional-integral-derivative load frequency control and involves uncertain parameters and time delays.The model of the system is firstly established,following which the system is transformed into a closed-loop system with feedback control.On this basis,a new augmented Lyapunov-Krasovskii(LK)functional is established for using the new Bessel-Legendre inequality to estimate the derivative of the functional,which can provide a maximum lower bound.A stability criterion is then derived by employing the LK functional and Bessel-Legendre inequality.Finally,numerical examples are used to demonstrate the validity and superiority of the proposed method. | Li Shen Huiqin Xiao | 2019 | Chinese Journal of Electrical Engineering2019，5，2： | 6 |
| 3 | Enhancement of innate immune system in monocot rice by transferring the dicotyledonous elongation factor Tu receptor EFR显示文摘The elongation factor Tu(EF-Tu) receptor(EFR) in cruciferous plants specifically recognizes the N-terminal acetylated elf18 region of bacterial EF-Tu and thereby activates plant immunity.It has been demonstrated that Arabidopsis EFR confers broad-spectrum bacterial resistance in the EFR transgenic solanaceous plants.Here,the transgenic rice plants(Oryza sativa L.ssp.japonica cv.Zhonghua 17) and cell cultures with constitutive expression of AtEFR were developed to investigate whether AtEFR senses EF-Tu and thus enhances bacterial resistance in the monocot plants.We demonstrated that the Xanthomonas oryzae-derived elf18 peptide induced oxidative burst and mitogen-activated protein kinase activation in the AtEFR transgenic rice cells and plants,respectively.Pathogenesis-related genes,such as OsPBZ1,were upregulated dramatically in transgenic rice plant and cell lines in response to elf18 stimulation.Importantly,pretreatment with elf18 triggered strong resistance to X.oryzae pv.oryzae in the transgenic plants,which was largely dependent on the AtEFR expression level.These plants also exhibited enhanced resistance to rice bacterial brown stripe,but not to rice fungal blast.Collectively,the results indicate that the rice plants with heterologous expression of AtEFR recognize bacterial EF-Tu and exhibit enhanced broad-spectrum bacterial disease resistance and that pattern recognition receptor-mediated immunity may be manipulated across the two plant classes,dicots and monocots. | Fen Lu Huiqin Wang Shanzhi Wang Wendi Jiang Changlin Shan Bin Li Jun Yang Shiyong Zhang Wenxian Sun | 2015 | Journal of Integrative Plant Biology2015，57，7： | 6 |
| 4 | Effects of volumetric allocation on heave response of semisubmersible in deep sea显示文摘The configuration of semisubmersibles consisting of pontoons and columns and their corresponding heave motion response in incident progressive waves are examined. The purpose of the present study is to provide a theoretical approach to estimating the effects of volumetric allocation on natural period and response amplitude operator (RAO) in heave motion. We conclude that the amplitude of heave motion response can be considerably suppressed by appropriately adjusting volumetric allocation so that the natural heave period keeps away from the range of wave energy. The theoretical formulae are found in good agreement with the corresponding computational results by WAMIT. | ZHANG HuiQin LI JiaChun | 2009 | Science China(Technological Sciences)2009，52，3： | 5 |
| 5 | The role of cupric in maintaining the structure of CopC显示文摘The CopC protein from pseudomonas syringae pathovar tomato is expressed as one of four proteins encoded by the operon CopABCD that is responsible for copper resistance. And there are one trypto-phan (83), one tyrosine (79), and three phenylalanines (35, 43, 99) in apoCopC. The fluorescence peak of apoCopC is located near 320 nm, and the peak shifts toward 353 nm in the presence of 10 mmol·L^(-1) urea with excitation at 280 nm. Using urea as a chemical agent, the conformational stabilities of apoCopC and Cu_N^(2+) -CopC were monitored by fluorescence spectrum in 20 mmol·L^(-1) phosphate buffer and 100 mmol·L^(-1) sodium chloride at pH 6.0. The free energy of stabilization for apoCopC and Cu_N^(2+)-CopC is 16.29±0.65 kJ·mol^(-1) and 26.26±0.35 kJ·mol^(-1), respectively. The distance between the tryptophan residue and the Cu^(2+) in Cu_N^(2+) -CopC has been studied by observing Frster type nonradia-tive energy transfer. And it is calculated to be 11.6 . | ZHENG XiaoYan PANG ErGuo LI HuiQin ZHAO YaQin YANG BinShengt | 2007 | Chinese Science Bulletin2007，52，6： | 4 |
| 6 | Variation and heritability of morphological and physiological traits among Leymus chinensis genotypes under different environmental conditions显示文摘Intraspecific trait variation and heritability in different environmental conditions not only suggest a potential for an evolutionary response but also have important ecological consequences at the population, community, and ecosystem levels. However, the contribution of quantitative trait variation within a grassland species to evolutionary responses or ecological consequences is seldom documented. Leymus chinensis is an important dominant species in semi-arid grasslands of China, which has seriously suffered from drought and high temperature stresses in recent decades. In the present study, we measured variation and heritability of 10 quantitative traits, namely the number of tillers, maximum shoot height, number of rhizomes, maximum rhizome length, rhizome mass, aboveground mass, root mass, maximum net photosynthetic rate(Pmax), specific leaf area(SLA), and leaf length to leaf width ratio(LL/LW), for 10 genotypes of L. chinensis under one non-stress(Ck) condition and three environmental stress conditions(i.e., drought(Dr), high temperature(Ht), and both drought and high temperature(DrHt)). Result indicated that(1) the interaction of genotype and environmental condition(G×E) was significant for 6 traits but not significant for the other 4 traits as shown by two-way analysis of variance(ANOVA), suggesting that different selection forces were placed for different traits on the factors dominating phenotypic responses to different environmental conditions. Moreover, these significant G×E effects on traits indicated significantly different phenotypic adaptive responses among L. chinensis genotypes to different environmental conditions. Additionally, individuals could be grouped according to environmental condition rather than genotype as shown by canonical discriminant analysis, indicating that environmental condition played a more important role in affecting phenotypic variation than genotype;(2) by one-way ANOVA, significant differences among L. chinensis genotypes were found in all 10 traits under Ck and Dr conditions, in 8 traits under Dr Ht condition and only in 4 traits under Ht condition; and(3) all 10 traits showed relatively low or non-measurable broad-sense heritability(H_2) under stress conditions. However, the lowest H_2 value for most traits did not occur under DrHt condition, which supported the hypothesis of 'unfavorable conditions have unpredictable effects' rather than 'unfavorable conditions decrease heritability'. Results from our experiment might aid to improve predictions on the potential impacts of climate changes on L. chinensis and eventually species conservation and ecosystem restoration. | YANG Xue LI Junpeng ZHAO Tingting MO Lidong ZHANG Jianli REN Huiqin ZHAO Nianxi GAO Yubao | 2019 | Journal of Arid Land2019，11，1： | 4 |

| 8 | Toxoplasma gondii GRA15II effector-induced M1 cells ameliorate liver fibrosis in mice infected with Schistosomiasis japonica显示文摘Recent studies indicated that type II Toxoplasma gondii(Tg)GRA15II favored the generation of classically activated macrophages(M1),whereas type I/III TgROP16I/III promoted the polarization of alternatively activated macrophages(M2).A number of studies have demonstrated that M2 cells are involved in the pathogenesis of the liver fibrogenesis caused by Schistosoma japonicum.The purpose of the present study was to explore the inhibitory effect of Toxoplasma-derived TgGRA15II on mouse hepatic fibrosis with schistosomiasis.The gra15II and rop16I/III genes were amplified from strains T.gondii PRU and Chinese 1 Wh3,respectively.Lentiviral vectors containing the gra15II or rop16I/III plasmid were constructed and used to infect the RAW264.7 cell line.The polarization of the transfected cells was evaluated,followed by co-culture of the biased macrophages with mouse hepatic stellate JS1 cells.Then,mice were injected with GRA15II-driven macrophages via the tail vein and infected with S.japonicum cercariae.TgGRA15II induced a M1-biased response,whereas TgROP16I/III drove the macrophages to a M2-like phenotype.The in vitro experiments indicated that JS1 cell proliferation and collagen synthesis were decreased following co-culture with TgGRA15II-activated macrophages.Furthermore,mice inoculated with TgGRA15II-biased macrophages displayed a notable alleviation of collagen deposition and granuloma formation in their liver tissues.Our results suggest that TgGRA15II-induced M1 cells may dampen the M2 dominant pathogenesis of hepatic fibrosis and granulomatosis.These results provide insights into the use of parasite-derived immunomodulators as potential anti-fibrosis agents and to re-balance the schistosomiasis-induced immune response. | Yuanyuan Xie Huiqin Wen Ke Yan Shushu Wang Xuesong Wang Jian Chen Yuanling Li Yuanhong Xu Zhengrong Zhong Jilong Shen Deyong Chu | 2018 | Cellular & Molecular Immunology2018，15，2： | 4 |

| 10 | A novel quality evaluation method for magnolia bark using electronic nose and colorimeter data with multiple statistical algorithms显示文摘Background:Magnolia bark(Magnolia Officinalis REHD.&WILS.and Magnolia officinalis REHD.&WILS.VAR.biloba REHD.&WILS,Hou Po in Chinese),is widely applied in clinical prescriptions and Chinese patent medicines.Origin place is a crucial factor affecting the quality of Hou Po,and chemical composition is an important index for evaluating its quality,which is closely related to its clinical efficacy.This study aims to develop a novel method for rapidly,accurately and comprehensively identifying the origin places of Hou Po and predicting the contents of its important chemical components.Methods:High performance liquid chromatography was used to analyze the contents of magnolol and honokiol and ultra-performance liquid chromatography the contents of magnocurarine and magnoflorine.The cold soak method was used to determine the contents of water-soluble extracts.The E-nose and colorimeter were used to determine the odor and color characteristics,respectively,of the collected Hou Po samples.Results:Using several statistical algorithms,different discriminant models based on the E-nose and colorimeter data were established to distinguish the origin place of Hou-Po and predict the chemical components of honokiol,magnolol,magnocurarine,magnoflorine and water-soluble extracts.The results showed that the Random Forest classifier combined with the ten-fold cross-validation method provided the highest classification accuracy for origin place,accounting for 99.53%among these models.The correlation coefficients between predicted and experimental values of the five chemical components were all higher than 0.96.Conclusion:This study has indicated that the electronic nose and colorimeter are promising methods for evaluating the quality of Chinese herbal medicines both qualitatively and quantitatively. | Jiahui Li Yuanyang Shao Yuebao Yao Yuetong Yu Guangzhao Cao Huiqin Zou Yonghong Yan | 2020 | Journal of Traditional Chinese Medical Sciences2020，7，2： | 4 |
| 11 | An Examination of the Predictability of Tropical Cyclone Genesis in High-Resolution Coupled Models with Dynamically Downscaled Coupled Data Assimilation Initialization显示文摘Predicting tropical cyclone(TC)genesis is of great societal importance but scientifically challenging.It requires fineresolution coupled models that properly represent air−sea interactions in the atmospheric responses to local warm sea surface temperatures and feedbacks,with aid from coherent coupled initialization.This study uses three sets of highresolution regional coupled models(RCMs)covering the Asia−Pacific(AP)region initialized with local observations and dynamically downscaled coupled data assimilation to evaluate the predictability of TC genesis in the West Pacific.The APRCMs consist of three sets of high-resolution configurations of the Weather Research and Forecasting−Regional Ocean Model System(WRF-ROMS):27-km WRF with 9-km ROMS,and 9-km WRF with 3-km ROMS.In this study,a 9-km WRF with 9-km ROMS coupled model system is also used in a case test for the predictability of TC genesis.Since the local sea surface temperatures and wind shear conditions that favor TC formation are better resolved,the enhanced-resolution coupled model tends to improve the predictability of TC genesis,which could be further improved by improving planetary boundary layer physics,thus resolving better air−sea and air−land interactions. | Mingkui LI Shaoqing ZHANG Lixin WU Xiaopei LIN Ping CHANG Gohkan DANABASOGLU Zhiqiang WEI Xiaolin YU Huiqin HU Xiaohui MA Weiwei MA Haoran ZHAO Dongning JIA Xin LIU Kai MAO Youwei MA Yingjing JIANG Xue WANG Guangliang LIU Yuhu CHEN | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |
| 12 | Photoelectrochemical performance of birnessite films and photoelectrocatalytic activity toward oxidation of phenol显示文摘Birnessite films on fluorine-doped tin oxide(FTO) coated glass were prepared by cathodic reduction of aqueous KMnO_4. The deposited birnessite films were characterized with X-ray diffraction, Raman spectroscopy, scanning electron microscopy and atomic force microscopy.The photoelectrochemical activity of birnessite films was investigated and a remarkable photocurrent in response to visible light was observed in the presence of phenol, resulting from localized manganese d–d transitions. Based on this result, the photoelectrocatalytic oxidation of phenol was investigated. Compared with phenol degradation by the electrochemical oxidation process or photocatalysis separately, a synergetic photoelectrocatalytic degradation effect was observed in the presence of the birnessite film coated FTO electrode.Photoelectrocatalytic degradation ratios were influenced by film thickness and initial phenol concentrations. Phenol degradation with the thinnest birnessite film and initial phenol concentration of 10 mg/L showed the highest efficiency of 91.4% after 8 hr. Meanwhile, the kinetics of phenol removal was fit well by the pseudofirst-order kinetic model. | Huiqin Zhang Hongrui Ding Xin Wang Cuiping Zeng Anhuai Lu Yan Li Changqiu Wang | 2017 | Journal of Environmental Sciences2017，29，2： | 3 |
| 13 | Deciphering Ascorbic Acid Regulatory Pathways in Ripening Tomato Fruit Using a Weighted Gene Correlation Network Analysis Approach显示文摘Genotype is generally determined by the co-expression of diverse genes and multiple regulatory pathways in plants.Gene co-expression analysis combining with physiological trait data provides very important information about the gene function and regulatory mechanism.L-Ascorbic acid(AsA),which is an essential nutrient component for human health and plant metabolism,plays key roles in diverse biological processes such as cell cycle,cell expansion,stress resistance,hormone synthesis,and signaling.Here,we applied a weighted gene correlation network analysis approach based on gene expression values and AsA content data in ripening tomato(Solanum lycopersicum L.)fruit with different AsA content levels,which leads to identifcation of AsA relevant modules and vital genes in AsA regulatory pathways.Twenty-four modules were compartmentalized according to gene expression profling.Among these modules,one negatively related module containing genes involved in redox processes and one positively related module enriched with genes involved in AsA biosynthetic and recycling pathways were further analyzed.The present work herein indicates that redox pathways as well as hormone-signal pathways are closely correlated with AsA accumulation in ripening tomato fruit,and allowed us to prioritize candidate genes for follow-up studies to dissect this interplay at the biochemical and molecular level. | Chao Gao Zheng Ju Shan Li Jinhua Zuo Daqi Fu Huiqin Tian Yunbo Luo Benzhong Zhu | 2013 | Journal of Integrative Plant Biology2013，55，11： | 3 |
| 14 | Relaxor behavior and Raman spectra of CuO-doped Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)ferroelectric ceramics显示文摘In this work,Raman spectra and dielectricity-temperature dependence measurements were used to investigate the B-site order degree in CuO-doped Pb(Mg_(1/3)Nb_(2/3))O_(3)-PbTiO_(3)ferroelectric ceramics.The measurement results indicated a typical relaxor characteristic for all samples.With the increasing of CuO doping content,the B-site order degree increased first and then decreased.However,the frequency dispersion and the relaxation degree decreased first and then increased while the CuO addition content was increasing,which was thought to be strongly correlated with the variations of the B-site order.The opposite variation tendency of the B-site order degree and the relaxation degree revealed that the phase transition dispersity is closely related to the order-disorder behaviors. | Huiqin LI Jingsong LIU Hongtao YU Shuren ZHANG | 2014 | Journal of Advanced Ceramics2014，3，3： | 2 |

| 16 | Effects of incident wind/wave directions on dynamic response of a SPAR-type floating offshore wind turbine system显示文摘As a promising renewable energy,offshore wind energy currently is gaining more attention,by which the economic and efficient operation of floating wind turbine systems is a potential research direction.This study is primarily devoted to the analysis of dynamic response of the NREL-5 MW reference wind turbine supported by an OC3-Hywind SPAR-type platform using a recompiled code which combines FAST with WAMIT.To verify the reliability of the recompiled code,the free decay motions of a floating wind turbine system in still water are examined with satisfactory results.After that,thirteen scenarios with different angles between wind and wave from 0°to 90°are investigated.The dynamic responses of the turbine system in various degrees of freedom(DOFs)for different incident wind/wave directions are presented in both time and frequency domains via the fast Fourier transform. | Guoqin Lyu Huiqin Zhang Jiachun Li | 2019 | Acta Mechanica Sinica2019，35，5： | 2 |
| 17 | 3D-cubic interconnected porous Mg-based scaffolds for bone repair显示文摘Mg-based porous materials,as potential bone tissue engineering scaffolds,are considered an attractive strategy for bone repair owing to favorable biodegradability,good biocompatibility and suitable mechanical properties.In this work,3D-cubic interconnected porous Mg–xZn–0.3Ca(x=0,3,6)scaffolds were prepared to obtain desirable pore structures with a mean porosity up to 73%and main pore size of 400–500μm,which pore structures were close to the human cancellous bone.The structure–property relationships in the present scaffolds were analyzed by experiments and theoretical models of generalized method of cells(GMC).Mg–xZn–0.3Ca scaffolds exhibited good compression properties with a maximum above 5MPa in yield strength and about 0.4GPa in elastic modulus.This was attributed to not only the alloy strengthening but also the large minimum solid area.On the other hand,the scaffolds showed undesirable and relatively serious degradation behavior in Hank’s solution,resulting from Zn addition in Mg-based scaffolds and the high surface area ratio in the pore structure.Therefore,surface modifications are worth studying for controlled degradation in the future.In conclusion,this research would explore a novel attempt to introduce 3D-cubic pore structure for Mg-based scaffolds,and provide new insights into the preparations of Mg-based scaffolds with good service performances for bone repair. | Qiangsheng Dong Yang Li Huiqin Jiang Xingxing Zhou Huan Liu Mengmeng Lu Chenglin Chu Feng Xue Jing Bai | 2021 | Journal of Magnesium and Alloys2021，9，4： | 2 |

| 19 | Fabricated temperature sensitive photocatalyst of PNIPAM@ZnO/C for controllable photocatalytic activity显示文摘PNIPAM@ZnO/C composite photocatalyst was prepared by cross-linking polymerization technology with N-isopropylacrylamide used as functional monomer, N,N'-methylenebis(acrylamide) used as crosslinking agent, ammonium persulfate used as initiator, and 3-(trimethoxysilyl) propyl methacrylate used as surface modification reagent. The morphology, structure, electrochemical and photocatalytic properties of as-prepared samples were characterized via the serial tests. The temperature-response performances of PNIPAM@ZnO/C were evaluated by the photocatalytic degradation of tetracycline(TC)under different temperatures. The results show that the synthesized composite photocatalysts possess the excellent and switchable photocatalytic activity. The photocatalytic degradation activity of PNIPAM@ZnO/C is suppressed above the lower critical solution temperature(LCST), and it is enhanced below the LCST. | Pengwei Huo Jinze Li Zhefei Ye Huiqin Wang Xinlin Liu Xiuying Li Yongsheng Yan | 2017 | Chinese Chemical Letters2017，28，12： | 2 |
| 20 | Mutual authenticated quantum no-key encryption scheme over private quantum channel显示文摘In this paper, we realize Shamir's no-key protocol via quantum computation of Boolean functions and a private quantum channel. The proposed quantum no-key protocol has three rounds and provides mutual data origin authentication. Random Boolean functions are used to create entanglement and guarantee that any adversary without keys cannot pass the authentication. Thus, our protocol can resist the manin-the-middle attack. A security analysis has shown that pieces of ciphertexts of the three rounds are completely mixed state. This property ensures no adversary can get any information about the sent message or authentication keys. Therefore, our protocol is unconditionally secure and its authentication keys can be reused. | Li YANG Chenmiao WU Huiqin XIE | 2018 | Science China(Information Sciences)2018，61，2： | 2 |
