| 4 | Research progress of nanoparticles as enzyme mimetics显示文摘Natural enzymes as biological catalysts possess remarkable advantages,especially their highly efficient and selective catalysis under mild conditions.However,most natural enzymes are proteins,thus exhibiting an inherent low durability to harsh reaction conditions.Artificial enzyme mimetics have been pursued extensively to avoid this drawback.Quite recently,some inorganic nanoparticles(NPs) have been found to exhibit unique enzyme mimetics.In addition,their much higher stability overcomes the inherent disadvantage of natural enzymes.Furthermore,easy mass-production and low cost endow them more benefits.As a new member of artificial enzyme mimetics,they have received intense attention.In this review article,major progress in this field is summarized and future perspectives are highlighted. | HU XiaoNa LIU JianBo HOU Shuai WEN Tao LIU WenQi ZHANG Ke HE WeiWei JI YingLu REN HongXuan WANG Qi WU XiaoChun | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 4 |
| 5 | Joint frequency offset tracking and PAPR reduction algorithm in OFDM systems显示文摘This paper presents an algorithm that aims to reduce the peak-to-average power ratio(PAPR) of orthogonal frequency division multiplexing(OFDM) communication systems while maintaining frequency tracking.The algorithm achieves PAPR reduction by applying the complex conjugates of the data symbol obtained from the frequency domain to cancel the phase of the data symbol.A likelihood estimator is used to obtain the sub-carrier phase error due to the residual carrier frequency offset(RCFO) using the same complex conjugates as a pilot signal.Furthermore,a joint time and frequency domain multicarrier phase locked loop(MPLL) is developed to compensate additional frequency offset.Simulation results show that this algorithm is capable of reducing PAPR without impacting the frequency tracking performance. | Lijun Ge Yingxin Zhao Hong Wu Ning Xu Yu'ang Jin Wenqi Li | 2010 | Journal of Systems Engineering and Electronics2010，21，4： | 4 |

| 7 | A double-filter-structure based COMPASS/INS deep integrated navigation system implementation and tracking performance evaluation显示文摘Beidou or COMPASS is a Chinese GNSS(global navigation satellite system).Like the GPS receiver,the COMPASS receiver also faces the challenge of choosing an optimal bandwidth to satisfy both anti-jamming capability and dynamics adaptation simultaneously.GPS/INS(inertial navigation system)deep integrated navigation system has solved this problem by fusing GPS baseband signal and INS information in a deeply coupled mode.In this study,a COMPASS B3 frequency is considered and a traditional federated GPS/INS deep integration model is used to derive a single-filter-structure based COMPASS/INS deep integration model.Besides,a double-filter-structure based COMPASS/INS deep integration model is proposed.The simulation results show a better carrier tracking performance,especially a better dynamics adaptation.The impact of IMU errors and vehicle’s dynamics on carrier tracking performance of the double-filter-structure based COMPASS/INS deep integrated navigation system are evaluated in simulated and field environments.Simulation and field test results are in accordance with the theory analysis. | LUO Yong WU WenQi BABU Ravindra TANG KangHua HE XiaoFeng | 2014 | Science China(Information Sciences)2014，57，1： | 4 |
| 8 | New flame retardant epoxy resins based on cyclophosphazene-derived curing agents显示文摘To obtain high-efficiency flame retardancy of epoxy resins,a cyclophosphazene derivative tri-(ohenylenediamino)cyclotriphosphazene(3 ACP)was successfully synthesized and used as a curing agent for the thermosetting of an epoxy resin system.The flame retardant properties,thermal stability,and pyrolysis mechanism of the resultant thermosets were investigated in detail.The experiments indicated that the synthesized thermoset achieved a UL-94 V-0 rate under a vertical burning test as well as a limiting oxygen index(LOI)of 29.2%,which was able to reach V-0 even when a small amount of 3 ACP was incorporated.Scanning electronic microscopic observation demonstrated that the char residue of the thermosets was extremely expanded after the vertical flame test.Thermal analysis showed that the samples had a lower initial decomposition temperature when 3 ACP was introduced into the epoxy resin systems.This indicates that the carbonization ability of the thermosets was significantly improved at elevated temperatures.In addition,the incorporation of 3 ACP can effectively suppress the release of combustible gases during the pyrolysis process,and the decomposition of E-44/DDS-3 ACP curing systems also promotes the formation of polyphosphoramides charred layer in the condensed phase.The investigation on the chemical structures of both the gaseous and condensed phase pyrolysis process confirmed the flame-retardant mechanism of the 3 ACP-cured epoxy resins.Therefore,the nonflammable halogen-free epoxy resin developed in this study has potential applications in electric and electronic fields for environment protection and human health. | Zhenwei Miao Dongpeng Yan Xiaodong Wang Xinfang Zhang Wenqi Zhou Munan Qiu Fan Yang Zhanpeng Wu | 2022 | Chinese Chemical Letters2022，33，8： | 3 |
| 9 | Quantitative climatic reconstruction of the Last Glacial Maximum in China显示文摘Quantitative paleoclimatic reconstruction is crucial for understanding the operation and evolution of the global climate system.For example,a quantitative paleoclimatic reconstruction for the Last Glacial Maximum(18±2 ka14C,LGM)is fundamental to understanding the evolution of Earth’s climate during the last glacial-interglacial cycle.Previous quantitative palaeoclimate reconstructions in China are generally based on statistical comparison of modern pollen assemblages and modern climate data.These methods are based on the premise that vegetation-climate interactions remain the same through time,and implicitly assume that the interactions are independent of changes in seasonality and atmospheric CO2concentration.However,these assumptions may not always be valid,which may affect the reconstructions.Here,we present the results of a quantitative study of the LGM climate of China based on an improved inverse vegetation model which incorporates physiological processes combined with a new China Quaternary Pollen Database.The results indicate that during the LGM,mean annual temperature(ANNT),mean temperature of the coldest month(MTCO)and mean temperature of the warmest month in China were lower by^5.6±0.8,~11.0±1.6 and^2.6±0.9°C,respectively,compared to today,and that the changes in ANNT were mainly due to the decrease of MTCO.The ANNT decrease in southern China was^5.5±0.5°C.Mean annual precipitation was lower by^46.3±17.8 mm compared to today and was especially low in northern China(~51.2±21.4 mm)due to the decrease in summer rainfall.Comparison of our results with recent outputs from paleoclimatic modelling reveals that while the latter are broadly consistent with our estimated changes in mean annual climatic parameters,there are substantial differences in the seasonal climatic parameters.Our results highlight the crucial importance of developing seasonal simulation on paleoclimatic models,as well as the need to improve the quality of paleoclimatic reconstructions based on proxy records from geological archives. | Haibin WU Qin LI Yanyan YU Aizhi SUN Yating LIN Wenqi JIANG Yunli LUO | 2019 | Science China Earth Sciences2019，62，8： | 3 |

| 11 | Phylogenetic Analysis of the Dengue Virus Strains Causing the 2019 Dengue Fever Outbreak in Hainan,China显示文摘Dengue virus is an arthropod-borne pathogen that is transmitted to humans primarily by Aedes spp.mosquitos,causing the acute infectious disease,dengue fever(DF).Until 2019,no dengue outbreak had been reported in Hainan Province for over 20 years.However,in early September of 2019,an increasing number of infected cases appeared and the DF outbreak lasted for over one month in Haikou City,Hainan Province.In our study,we collected 97 plasma samples from DF patients at three hospitals,as well as 1585 mosquito larvae samples from puddles in different areas of Haikou.There were 49(50.5%)plasma samples found to be strongly positive and 9(9.3%)plasma samples were weakly positive against the NS1 antigen.We discovered DENV both in the patient's plasma samples and mosquito larvae samples,and isolated the virus from C6/36 cells inoculated with the acute phase serum of patients.Phylogenetic analysis revealed that the new strains were the most closely related to the epidemic strain in the southern regions of China,belonging to lineageⅣ,genotypeⅠ,DENV-1.Compared to the seven closest strains from neighboring countries and provinces,a total of 18 amino acid mutations occurred in the coding sequences(CDS)of the new isolated strain,DENV1 HMU-HKU-2.Our data shows that dengue virus is re-emerged in Hainan,and pose new threats for public health.Thus regular molecular epidemiological surveillance is necessary for control and prevention of DENV transmission. | Jiang Du Liyuan Zhang Xiaoyuan Hu Ruoyan Peng Gaoyu Wang Yi Huang Wenqi Wang Kunliang Wu Qiang Wang Haoxiang Su Fan Yang Yun Zhang Chuanning Tang Xiuji Cui Lina Niu Gang Lu Meifang Xiao Yongguo Du Feifei Yin | 2021 | Virologica Sinica2021，36，4： | 2 |
| 12 | Modification of physicochemical properties and degradation of barley flour upon enzymatic extrusion显示文摘In order to evaluate the application potential of enzyme-extruded barley flour(EEBF)in the brewing of whole-barley beer,the physicochemical properties,mashing and fermentation effects of EEBF were studied,and conventional extruded barley flour(CEBF)and steam-cooked barley flour(SCBF)were taken as controls.The water solubility index(WSI)of EEBF(46.88%-52.63%)was much higher than that of CEBF(6.70%)and SCBF(4.59%).The results of degree of gelatinization(DG)and enthalpy(ΔH)suggested that EEBF was almost completely gelatinized,and the rapid visco analyzer(RVA)exhibited that the peak viscosity of EEBF was drastically reduced.The weight-average molecular weight of EEBF(<10^(6) g/mol)was significantly lower than that of CEBF and SCBF.Scanning electron microscopy(SEM)showed that the heat-treatments caused starch granules to break and aggregate,and there were many hydrolyzed pores on the surface of EEBF.Both the long-and short-range order of EEBF were destroyed.Although EEBF caused serious filtration blocking,it greatly improved the alcohol content of finished beer(5.41%vol).Overall,the thermal modification of barley flour by enzyme-extrusion meets the needs of fermentation,and could improve the problem of limited leaching of unmalted barley,which was benefit for the production of whole-barley beer. | Shuna Zhao Aiquan Jiao Yueyue Yang Qing Liu Wenqi Wu Zhengyu Jin | 2022 | Food Bioscience2022，45，1： | 2 |
| 13 | Hydrological Simulation Using TRMM and CHIRPS Precipitation Estimates in the Lower Lancang-Mekong River Basin显示文摘Satellite-based products with high spatial and temporal resolution provide useful precipitation information for data-sparse or ungauged large-scale watersheds. In the Lower Lancang-Mekong River Basin, rainfall stations are sparse and unevenly distributed, and the transboundary characteristic makes the collection of precipitation data more difficult, which has restricted hydrological processes simulation. In this study, daily precipitation data from four datasets(gauge observations, inverse distance weighted(IDW) data, Tropical Rainfall Measuring Mission(TRMM) estimates, and Climate Hazards Group InfraRed Precipitation with Stations(CHIRPS) estimates), were applied to drive the Soil and Water Assessment Tool(SWAT) model, and then their capability for hydrological simulation in the Lower Lancang-Mekong River Basin were examined. TRMM and CHIRPS data showed good performances on precipitation estimation in the Lower Lancang-Mekong River Basin, with the better performance for TRMM product. The Nash-Sutcliffe efficiency(NSE) values of gauge, IDW, TRMM, and CHIRPS simulations during the calibration period were 0.87, 0.86, 0.95, and 0.93 for monthly flow, respectively, and those for daily flow were 0.75, 0.77, 0.86, and 0.84, respectively. TRMM and CHIRPS data were superior to rain gauge and IDW data for driving the hydrological model, and TRMM data produced the best simulation performance. Satellite-based precipitation estimates could be suitable data sources when simulating hydrological processes for large data-poor or ungauged watersheds, especially in international river basins for which precipitation observations are difficult to collect. CHIRPS data provide long precipitation time series from 1981 to near present and thus could be used as an alternative precipitation input for hydrological simulation, especially for the period without TRMM data. For satellite-based precipitation products, the differences in the occurrence frequencies and amounts of precipitation with different intensities would affect simulation results of water balance components, which should be comprehensively considered in water resources estimation and planning. | LUO Xian WU Wenqi HE Daming LI Yungang JI Xuan | 2019 | Chinese Geographical Science2019，29，1： | 2 |

| 19 | A systems biology approach identifies a regulator,BplERF1,of cold tolerance in Betula platyphylla显示文摘Cold is an abiotic stress that can greatly affect the growth and survival of plants.Here,we reported that an AP2/ERF family gene,BplERF1,isolated from Betula platyphylla played a contributing role in cold stress tolerance.Overexpression of BplERF1 in B.platyphylla transgenic lines enhanced cold stress tolerance by increasing the scavenging capability and reducing H_(2)O_(2) and malondialdehyde(MDA)content in transgenic plants.Construction of BplERF-mediated multilayered hierarchical gene regulatory network(ML-hGRN),using Top-down GGM algorithm and the transcriptomic data of BplERF1 overexpression lines,led to the identification of five candidate target genes of BplERF1 which include MPK20,ERF9,WRKY53,WRKY70,and GIA1.All of them were then verified to be the true target genes of BplERF1 by chromatin-immunoprecipitation PCR(ChIP-PCR)assay.Our results indicate that BplERF1 is a positive regulator of cold tolerance and is capable of exerting regulation on the expression of cold signaling and regulatory genes,causing mitigation of reactive oxygen species. | Kaiwen Lv Wenqi Wu Hairong Wei Guifeng Liu | 2021 | Forestry Research2021，1，1： | 1 |
