| 3 | Development and characterization of a clinical strain of Coxsackievirus A16 and an eGFP infectious clone显示文摘Coxsackievirus A16(CA16) is one of the major causes of hand, foot, and mouth disease(HFMD) worldwide, which is a common illness that affects children. The frequent occurrence of HFMD outbreaks has become a serious public health problem in Asia. Therefore, it is important to understand the pathogenesis and replication of CA16. In this study, a stable infectious c DNA clone of an epidemic strain of Coxsackievirus A16(CA16) was assembled, and subsequently a reporter virus(e GFP-CA16) was constructed by inserting the e GFP gene between the 5'-UTR and the N-terminus of VP4, with the addition of a 2A protease cleavage site(ITTLG) at its C-terminus. This was transfected into Vero cells to generate infectious recombinant viruses. The growth characteristics and plaque morphology, in vitro, in mammalian cells were found to be indistinguishable between the parental and recombinant viruses. Although the e GFP-CA16 showed smaller plaque size as compared to recombinant CA16, both were found to exhibit similar growth trends and EC50 of NITD008. In summary, this stable infectious c DNA clone should provide a valuable experimental system to study CA16 infection and host response. The e GFP-CA16 is expected to provide a powerful tool to monitor e GFP expression in infected cells and to evaluate the antiviral activity of potential antiviral agents in the treatment of CA16 infections. | Chenglin Deng Xiaodan Li Siqing Liu Linlin Xu Hanqing Ye Cheng-Feng Qin Bo Zhang | 2015 | Virologica Sinica2015，30，4： | 5 |
| 4 | Trans Complementation of Replication-defective Omsk Hemorrhagic Fever Virus for Antiviral Study显示文摘Omsk hemorrhagic fever virus(OHFV) is a tick-borne flavivirus classified as a biosafety level-4(BSL4) pathogen. Studies of OHFV are restricted to be conducted within BSL4 laboratories. Currently, no commercial vaccines or antiviral drugs are available against OHFV infection. In this study, we recovered a replication-deficient OHFV with an NS1 deletion(OHFVDNS1) and reporter virus replacing NS1 with the Gaussia luciferase(Gluc)(OHFV-ΔNS1-Gluc). Both the defective OHFVDNS1 and OHFV-ΔNS1-Gluc virus could only replicate efficiently in the BHK21 cell line expressing NS1(BHK21NS1) but not in na?ve BHK21 cells. The Gluc reporter gene of OHFV-ΔNS1-Gluc virus was maintained stably after serial passaging of BHK21NS1 cells and was used to surrogate the replication of OHFV. Using NITD008, OHFV-ΔNS1-Gluc virus was validated for antiviral screening, and high-throughput screening parameters were optimized in a 96-well plate format with a calculated Z0 value above 0.5. The OHFV-ΔNS1-Gluc reporter virus is a powerful tool for antiviral screening as well as viral replication and pathogenesis studies in BSL2 laboratories. | Qiuyan Zhang Na Li Chenglin Deng Zherui Zhang Xiaodan Li Kentaro Yoshii Hanqing Ye Bo Zhang | 2019 | Virologica Sinica2019，34，4： | 4 |
| 5 | Experimental study on freezing of liquids under static magnetic field显示文摘Freezing processes of several liquids under static magnetic field(SMF) less than 50 mT were investigated. Central temperature of liquid samples held in glass test tubes immersed in a liquid bath was measured and collected. Nucleation temperature and phase transition time were obtained from freezing curves. Normality tests were performed for nucleation temperature of these liquids with/without magnetic field and normality distributions were justified. Analysis of variances was carried out for nucleation temperature of these liquids with magnetic field flux density as the influencing factor. Results showed that no significant difference was found for deionized water with or without SMF. However, differences exist in 0.9% NaCl solution and 5% ethylene glycol solution with and without SMF. Nucleation temperature of 0.9% NaCl with SMF is lower than that without SMF, while its phase transition time is shorter than that without SMF. Nucleation temperature of 5% ethylene glycol with SMF is higher than that without SMF, while its phase transition time is not modified with SMF. | Hongxia Zhao Feng Zhang Hanqing Hu Sheng Liu Jitian Han | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 4 |
| 6 | Sn02 nanoparticles anchored on graphene oxide as advanced anode materials for high-performance lithium-ion batteries显示文摘Lithium-ion batteries (LIBs) with high energy density have attracted great attention for their wide applications in electric vehicles, and the exploration of the nextgeneration anode materials with high theoretical capacity is highly desired. In this work, Sn02 nanoparticles with the particle size of 200 nm uniformly anchored on the surface of graphene oxide (GO) was prepared by combination of the ultrasonic method and the following calcination process. The Sn02/GO composite with the weight ratio of Sn02 to GO at 4:1 exhibits excellent electrochemical performance, which originates from the synergistic effects between GO and Sn02 nanoparticles. A high discharge capacity of 492 mA·h·g^-1 can be obtained after 100 cycles at 0.2C, and after cycling at higher current densities of 1C and 2C, a discharge capacity of 641 mA·h·g^-1 can be restored when the current density goes back to 0.1C. The superior electrochemical performance and simple synthesis process make it a very promising candidate as anode materials for LIBs. | Ruiping LIU Ning ZHANG Xinyu WANG Chenhui YANG Hui CHENG Hanqing ZHAO | 2019 | Frontiers of Materials Science2019，13，2： | 4 |
| 7 | A Superaerophobic Bimetallic Selenides Heterostructure for Efficient Industrial-Level Oxygen Evolution at Ultra-High Current Densities显示文摘Cost-effective and stable electrocatalysts with ultra-high current densities for electrochemical oxygen evolution reaction(OER)are critical to the energy crisis and environmental pollution.Herein,we report a superaerophobic three dimensional(3D)heterostructured nanowrinkles of bimetallic selenides consisting of crystalline NiSe2 and NiFe2Se4 grown on NiFe alloy(NiSe2/NiFe2Se4@NiFe)prepared by a thermal selenization procedure.In this unique 3D heterostructure,numerous nanowrinkles of NiSe2/NiFe2Se4 hybrid with a thickness of ~100 nm are grown on NiFe alloy in a uniform manner.Profiting by the large active surface area and high electronic conductivity,the superaerophobic NiSe2/NiFe2Se4@NiFe heterostructure exhibits excellent electrocatalytic activity and durability towards OER in alkaline media,outputting the low potentials of 1.53 and 1.54 V to achieve ultra-high current densities of 500 and 1000 mA cm^−2,respectively,which is among the most active Ni/Fe-based selenides,and even superior to the benchmark Ir/C catalyst.The in-situ derived FeOOH and NiOOH species from NiSe2/NiFe2Se4@NiFe are deemed to be efficient active sites for OER. | Jiaxin Yuan Xiaodi Cheng Hanqing Wang Chaojun Lei Sameer Pardiwala Bin Yang Zhongjian Li Qinghua Zhang Lecheng Lei Shaobin Wang Yang Hou | 2020 | Nano-Micro Letters2020，12，8： | 4 |

| 10 | In vitro comparison of the hemocompatibility of diamond-like carbon and carbon nitride coatings with different atomic percentages of N显示文摘Carbon nitride (CNx) and diamond-like carbon (DLC) coatings were prepared by dc magnetron sputtering at room temperature. Different partial pressures of N2 were used to synthesize CNx to evaluate the relationship between the atomic percentage of nitrogen and hemocompatibility. Auger electron spectroscopy and atomic force microscopy indicated atomic percentages of N of 0.12 and 0.22 and that the CNx coatings were smooth. An in vitro study of the hemocompatibility of the coatings revealed that both CNx coatings had better anticoagulant properties and lower platelet adhesion than DLC. Compared with CN0.12, the CN0.22 coating showed longer dynamic clotting time (about 42 min), static clotting time (23.6 min) and recalcification time (45.6 s), as well as lower platelet adhesion (102 cells μm 2), aggregation, and activation. The presence of nitrogen in the CNx coatings induced their enhanced hemocompatibility compared with DLC. | ZHAO MengLi LI DeJun ZHANG YiTeng GUO MeiXian DENG XiangYun GU HanQing WAN RongXin | 2012 | Science China(Life Sciences)2012，55，4： | 3 |

| 12 | Transmission line fault-cause identification method for large-scale new energy grid connection scenarios显示文摘The accurate fault-cause identification for overhead transmission lines supports the operation and maintenance personnel in formulating targeted maintenance strategies and shortening the time of inspecting faulty lines.With the goal of achieving“carbon peak and carbon neutrality”,the schemes for clean energy generation have rapidly developed.Moreover,new energy-consuming equipment has been widely connected to the power grid,and the operating characteristics of the power system have significantly changed.Consequently,these have impacted traditional fault identification methods.Based on the time-frequency characteristics of the fault waveform,new energy-related parameters,and deep learning model,this study proposes a fault identification method suitable for scenarios where a high proportion of new energy is connected to the power grid.Ten parameters related to the causes of transmission line fault and new energy connection scenarios are selected as model characteristic parameters.Further,a fault identification model based on adaptive deep belief networks was constructed,and its effect was verified by field data. | Hanqing Liang Xiaonan Han Haoyang Yu Fan Li Zhongjian Liu Kexin Zhang | 2022 | Global Energy Interconnection2022，5，4： | 3 |
| 13 | Double Position Servo Synchronous Drive System Based on Cross-Coupling Integrated Feedforward Control for Broacher显示文摘Synchronization errors directly deteriorate the machining accuracy of metal parts and the existed method cannot keep high synchronization precision because of external disturbances. A new double position servo synchronous driving scheme based on semi-closed-loop crosscoupling integrated feedforward control is proposed. The scheme comprises a position error cross-coupling feedforward control and a load torque identification with feedforward control. A digital integrated simulation system for the dual servo synchronous drive system is established.Using a 20 t servo broacher, performance analysis of the scheme is conducted based on this simulation system and the simulation results show that systems with traditional parallel or single control have problems when the worktable works with an unbalanced load. However, the system with proposed scheme shows good synchronous performance and positional accuracy. Broaching tests are performed and the experimental results show that the maximum dual axis synchronization error of the system is only 8 μm during acceleration and deceleration processes and the error between the actual running position and the given position is almost zero. A double position servo synchronous driving scheme is presented based on crosscoupled integrated feedforward compensation control,which can improve the synchronization precision. | Wenqi LU Kehui JI Hanqing DONG Jianya ZHANG Quanwu WANG Liang GUO | 2017 | Chinese Journal of Mechanical Engineering2017，30，2： | 2 |
| 14 | High reproducibility and sensitivity of bifacial copper nanowire array for detection of glucose显示文摘The ordered bifacial copper nanowire array(Cu BNWA) was synthesized by a template assisted electrochemical deposition method.The morphology and structure of the as-prepared samples were investigated by field emission scanning electron microscope(FESEM) and X-ray diffraction(XRD).The results show that the ordered Cu nanowire array with uniform geometrical dimensions covered both side of the Cu substrate.When used as the electrode for glucose detection,the minimum detectable concentration of glucose can be reached as low as 0.2 mM.Impressively,the sample still showed high sensitivity and stability for glucose detection after two months placement in ambient environment.These excellent performances of the Cu BNWA make it a promising non-enzyme glucose detection sensor for various applications. | Hanqing Zhang Yining Wang Xuesen Gao Zhuo Gao Yan Chen | 2017 | Progress in Natural Science:Materials International2017，27，3： | 2 |
| 15 | Chaos Particle Swarm Optimization Combined with Circular Median Filtering for Geophysical Parameters Retrieval from WindSat显示文摘This paper established a geophysical retrieval algorithm for sea surface wind vector, sea surface temperature, columnar atmospheric water vapor, and columnar cloud liquid water from WindSat, using the measured brightness temperatures and a matchup database. To retrieve the wind vector, a chaotic particle swarm approach was used to determine a set of possible wind vector solutions which minimize the difference between the forward model and the WindSat observations. An adjusted circular median filtering function was adopted to remove wind direction ambiguity. The validation of the wind speed, wind direction, sea surface temperature, columnar atmospheric water vapor, and columnar liquid cloud water indicates that this algorithm is feasible and reasonable and can be used to retrieve these atmospheric and oceanic parameters. Compared with moored buoy data, the RMS errors for wind speed and sea surface temperature were 0.92 m s^(-1) and 0.88℃, respectively. The RMS errors for columnar atmospheric water vapor and columnar liquid cloud water were 0.62 mm and 0.01 mm, respectively, compared with F17 SSMIS results. In addition, monthly average results indicated that these parameters are in good agreement with AMSR-E results. Wind direction retrieval was studied under various wind speed conditions and validated by comparing to the Quik SCAT measurements, and the RMS error was 13.3?. This paper offers a new approach to the study of ocean wind vector retrieval using a polarimetric microwave radiometer. | ZHANG Lei WANG Zhenzhan SHI Hanqing LONG Zhiyong DU Huadong | 2016 | Journal of Ocean University of China2016，15，4： | 2 |

| 17 | A novel method of periodic orbit computation in circular restricted three-body problem显示文摘Periodic orbits are fundamental keys to understand the dynamical system of circular restricted three-body problem, and they play important roles in practical deep-space exploration. Current methods of periodic orbit computation need a high-order analytical approximate solution to start the iteration process, thus making the computation complicated and limiting the types of periodic orbits that can be obtained. By utilizing the symmetry of the restricted three-body problem, a special kind of flow function is constructed, so as to map a state on the plane of symmetry to another state that also lies in this plane. Based on this flow function, a new method of periodic orbit computation is derived. This method needs neither a starting analytic approximation nor the state transition matrix to be computed, so it can be conveniently implemented on a computer. Besides, this method is unaffected by the nonlinearity of the dynamical system, allowing a large set of periodic orbits which have x-z plane symmetry to be computed numerically. As examples, some planar periodic orbits (e.g. Lyapunov orbit) and spatial periodic orbits (e.g. Halo orbit) are computed. By further combining with a differential correction process, the method introduced here can be used to design resonant orbits that can jump between different resonant frequencies. One such resonant orbit is given in this paper, verifying the efficiency of this method. | ZHANG HanQing LI YanJun ZHANG Ke | 2011 | Science China(Technological Sciences)2011，54，8： | 2 |
| 18 | The impact of the atmospheric turbulence-development tendency on new particle formation:a common finding on three continents显示文摘A new mechanism of new particle formation(NPF)is investigated using comprehensive measurements of aerosol physicochemical quantities and meteorological variables made in three continents,including Beijing,China;the Southern Great Plains site in the USA;and SMEARⅡStation in Hyytiala,Finland.D espite the considerably different emissions of chemical species among the sites,a common relationship was found between the characteristics of NPF and the stability intensity.The stability parameter(ζ=Z/L,where Z is the height above ground and L is the Monin-Obukhov length)is found to play an important role;it drops significantly before NPF as the atmosphere becomes more unstable,which may serve as an indicator of nucleation bursts.As the atmosphere becomes unstable,the NPF duration is closely related to the tendency for turbulence development,which influences the evolution of the condensation sink.Presumably,the unstable atmosphere may dilute pre-existing particles,effectively reducing the condensation sink,especially at coarse mode to foster nucleation.This new mechanism is confirmed by model simulations using a molecular dynamic model that mimics the impact of turbulence development on nucleation by inducing and intensifying homogeneous nucleation events. | Hao Wu Zhanqing Li Hanqing Li Kun Luo Yuying Wang Peng Yan Fei Hu Fang Zhang Yele Sun Dongjie Shang Chunsheng Liang Dongmei Zhang Jing Wei Tong Wu Xiaoai Jin Xinxin Fan Maureen Cribb Marc L.Fischer Markku Kulmala Tuukka Petaja | 2021 | National Science Review2021，8，3： | 2 |
| 19 | WindSat satellite comparisons with nearshore buoy wind data near the U.S. west and east coasts显示文摘Nearshore wind speeds retrieved by WindSat are validated by a comparison with the moored buoy observations near the U.S.west and east coasts.A 30 min and 25 km collection window is used for the Wind Sat wind data and buoy measurements from January 2004 to December 2014.Comparisons show that the overall root-mean-square error is better than 1.44 m/s near the U.S.coasts,and the result for the east coast is better than that for the west coast.The retrieval accuracy of the descending portions is slightly better than that of the ascending portions.Most buoy-to-buoy variations are not significantly correlated with the coastal topography,the longitude and the distance from the shore or satellite-buoy separation distance.In addition,comparisons between a polarimetric microwave radiometer and a microwave scatterometer are accomplished with the nearshore buoy observations from 2007 to 2008.The Wind Sat-derived winds tend to be lower than the buoy observations near the U.S.coasts.In contrast,the Quik SCAT-derived winds tend to be higher than the buoy observations.Overall,the retrieval accuracy of Wind Sat is slightly better than that of Quik SCAT,and these satellite-derived winds are sufficiently accurate for scientific studies. | ZHANG Lei SHI Hanqing YU Hong YI Xin | 2016 | Acta Oceanologica Sinica2016，35，7： | 2 |
| 20 | Impact of Taihu Lake on City Ozone in the Yangtze River Delta显示文摘The lake-breeze at Taihu Lake generates a different specific heat capacity between the water body and the surrounding land. Taihu Lake has a significant impact on the atmospheric conditions and the air quality in the Yangtze River Delta. This phenomenon is referred to as the Taihu Lake effect. In this study, two simulations were conducted to determine the impact of the Taihu Lake effect in the reference experiment(R-E) and sensitivity experiments(NO TH). The control simulations demonstrated that the meteorological field and the spatial distribution of ozone(O3) concentrations over Taihu lake obviously changed once the land-use type of water body was substituted by cropland. The surface temperature of Taihu Lake was reduced under the impact of Taihu Lake, and a huge temperature difference caused a strong lake-breeze effect. The results also showed that the difference in the average concentrations of O3 between the R-E and NO TH experiments reached 12 ppbv in most areas of Taihu Lake, all day, on 20 May 2014. During daytime(0800–1600 LST, LST=UTC+8), the influence of the Taihu Lake effect on O3 in the Suzhou region was not significant. However, the influence of the Taihu Lake effect on O3 in the Suzhou region was obvious during nighttime(1800–2400 LST). The larger changes in the physical and chemical processes were horizontal and vertical advections under the influence of the Taihu Lake effect in Taihu Lake. | Liang ZHANG Bin ZHU Jinhui GAO Hanqing KANG | 2017 | Advances in Atmospheric Sciences2017，34，2： | 2 |
