| 2 | A Multisource Contour Matching Method Considering the Similarity of Geometric Features显示文摘The existing multi-source contour matching studies have focused on the matching methods with consideration of topological relations and similarity measurement based on spatial Euclidean distance,while it is lack of taking the contour geometric features into account,which may lead to mismatching in map boundaries and areas with intensive contours or extreme terrain changes.In light of this,it is put forward that a matching strategy from coarse to precious based on the contour geometric features.The proposed matching strategy can be described as follows.Firstly,the point sequence is converted to feature sequence according to a feature descriptive function based on curvature and angle of normal vector.Then the level of similarity among multi-source contours is calculated by using the longest common subsequence solution.Accordingly,the identical contours could be matched based on the above calculated results.In the experiment for the proposed method,the reliability and efficiency of the matching method are verified using simulative datasets and real datasets respectively.It has been proved that the proposed contour matching strategy has a high matching precision and good applicability. | Wenyue GUO Anzhu YU Qun SUN Shaomei LI Qing XU Bowei WEN Yuanfu LI | 2020 | Journal of Geodesy and Geoinformation Science2020，3，3： | 5 |
| 3 | Deep learning-enabled triboelectric smart socks for IoT-based gait analysis and VR applications显示文摘The era of artificial intelligence and internet of things is rapidly developed by recent advances in wearable electronics.Gait reveals sensory information in daily life containing personal information,regarding identification and healthcare.Current wearable electronics of gait analysis are mainly limited by high fabrication cost,operation energy consumption,or inferior analysis methods,which barely involve machine learning or implement nonoptimal models that require massive datasets for training.Herein,we developed low-cost triboelectric intelligent socks for harvesting waste energy from low-frequency body motions to transmit wireless sensory data.The sock equipped with self-powered functionality also can be used as wearable sensors to deliver information,regarding the identity,health status,and activity of the users.To further address the issue of ineffective analysis methods,an optimized deep learning model with an end-to-end structure on the socks signals for the gait analysis is proposed,which produces a 93.54%identification accuracy of 13 participants and detects five different human activities with 96.67%accuracy.Toward practical application,we map the physical signals collected through the socks in the virtual space to establish a digital human system for sports monitoring,healthcare,identification,and future smart home applications. | Zixuan Zhang Tianyiyi He Minglu Zhu Zhongda Sun Qiongfeng Shi Jianxiong Zhu Bowei Dong Mehmet Rasit Yuce Chengkuo Lee | 2020 | npj Flexible Electronics2020，4，1： | 4 |
| 4 | Anti-rutting performance evaluation of modified asphalt binders: A review显示文摘Asphalt pavement inevitably suffers rutting distress induced by repeated loads under high temperatures, which can be effectively alleviated by the modification of asphalt binders.This paper summarized the asphalt modifiers for enhancing the performance of asphalt pavement at high temperatures in terms of the modifier type, additive amount and improving effect. Then, the anti-rutting performance evaluation methods of asphalt binder were introduced with details, including the ring and ball(R&B) test, the dynamic viscosity test, the zero/low shear viscosity(ZSV/LSV) test, the dynamic shear rheometer(DSR) test,the repeated creep and recovery(RCR) test, and the multiple stress creep and recovery(MSCR) test. Furthermore, the sensitivity of the evaluation method to asphalt modifier was analyzed using the normalization method. It was found that the indicators from the MSCR test could clearly reveal the influence of asphalt modifiers on high temperature performance of asphalt binder. But it still had some limitations affecting the accuracy of evaluation results, such as the number of creep-recovery cycles, the stress level and the recovery time. In addition, according to the rutting resistance improvement ratio(RRIR),the styrene-butadiene-styrene(SBS) modifier performed better in improving the rutting resistance of asphalt binder, compared with other modifiers when added within the usual dosage range. | Yan Li Peiwen Hao Chaozhi Zhao Jwnqiang Ling Tao Wu Dewen Li Jingwen Liu Bowei Sun | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，3： | 4 |
| 5 | Incorporation of nano/micron-SiC particles in Ni-based composite coatings towards enhanced mechanical and anti-corrosion properties显示文摘Ni-based composite coatings incorporated with nano/micron SiC particles were fabricated via electrochemical co-deposition in Watts bath,followed by the evaluation of their mechanical and anti-corrosion properties.The micrographic observations suggest that the SiC particles with various sizes can be well incorporated to the Ni substrate.X-ray diffraction(XRD)patterns indicate that SiC particles with smaller sizes could weaken the preferential growth of Ni along(200)facet.In addition,it is found that the incorporated SiC particles with medium micron sizes(8 and 1.5μm)could significantly enhance the micro-hardness of the Ni composite coatings.Nevertheless,electrochemical measurements demonstrate that micron-sized SiC particles would weaken the corrosion resistance of Ni composite coatings ascribed to the structure defects induced.In contrast,the combined incorporation of nanosized(50 nm)SiC particles with medium micron(1.5μm)ones is capable of promoting the compactness of the composite coatings,which is beneficial to the long-term corrosion resistance with negligible micro-hardness loss. | Bowei Zhang Qiao Zhang Zhan Zhang Kui Xiao Qiong Yao Guojia Ma Gang Sun Junsheng Wu | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 2 |
| 6 | Studies on Surface Properties and Cell Adhesion Properties of BSA Modified DBM Scaffold显示文摘As a scaffold material for bone tissue engineering, demineralized bone matrix(DBM) has such a limited ability to load cells and growth factors that the surface of the DBM scaffold was modified with bovine serum albumin(BSA) with different concentrations to improve the protein stmcture and physicochemical properties of the scaffold surface so as to enhance the adhesion of the cells. And the appropriate BSA concentration was explored. Compared with DBM, the scaffold with BSA coating had a smaller pore size and a lower porosity, also, the degradation rate was accelerated and the hydrophilic property was improved. Cells adhesion was observed inside the DBM seaffold before and after it had been modified, and the BSA modified scaffold had a good cell compatibility. Wlien the concentration of BSA was 20 mg/mL, the adhesion ability of the cells to modified scaffold was significantly increased, and the cell proliferation was facilitated. | SUN Mengjie FENG Wei WANG Bowei HAN Bing ZOU Jundong YANG Chunying LIU Zhihui | 2019 | Chemical Research in Chinese Universities2019，35，4： | 1 |
| 7 | Unravelling the effects of complexation of transition metal ions on the hydroxylation of catechol over the whole pH region显示文摘Catechol pollutants(CATPs)serving as chelating agents could coordinate with many metal ions to form various CATPs-metal complexes.Little information is available on the effects of complexation of metal ions on CATPs degradation.This work presents a systematical study of·OH-mediated degradation of catechol and catechol-metal complexes over the whole pH range in advanced oxidation processes(AOPs).Results show that the pH-dependent complexation of metal ions(Zn^(2+),Cu^(2+),Ti^(4+)and Fe^(3+))promotes the deprotonation of catechol under neutral and even acidic conditions.The radical adduct formation(RAF)reactions are both thermodynamically and kinetically favorable for all dissociation and complexa-tion species,and-OH/-O-group-containing C positions are more vulnerable to·OH attack.The kinetic results show that the complexation of the four metal ions offers a wide pH range of effectiveness for catechol degradation.At pH 7,the apparent rate constant(k_(app))values for different systems follow the order of catechol+Ti^(4+)≈catechol+Zn^(2+)>catechol+Cu^(2+)>catechol+Fe^(3+)>catechol.The mechanistic and kinetic results would greatly improve our understanding of the degradation of CATPs-metal and other organics-metal complexes in AOPs.The toxicity assessment indicates that the·OH-based AOPs have the ability for decreasing the toxicity and increasing the biodegradability during the processes of catechol degradation. | Zexiu An Jianfei Sun Qiong Mei BoWei Mingxue Li Ju Xie Maoxia He Qiao Wang | 2022 | Journal of Environmental Sciences2022，34，5： | 1 |

| 9 | Crude oil mobility and its controlling factors in tight sand reservoirs in northern Songliao Basin, East China显示文摘Taking tight oil in Gaotaizi and Fuyu oil layers of the Upper Cretaceous Qingshankou Formation in northern Songliao Basin as an example, based on analyses of nuclear magnetic resonance and high pressure mercury injection, experiment methods of supercritical carbon dioxide displacement and extraction are firstly employed to quantify crude oil mobility in tight sand reservoirs with different lithologies and oil contents. The results show that, under the conditions of simulating the Cretaceous Qingshankou Formation in the northern Songliao Basin at a temperature of 76-89 °C and a pressure of 35-42 MPa, the lower limit of the porosity of the movable oil is4.4%, and the lower limit of the permeability is 0.015′10-3 mm2. The lower limit of the average pore throat radius is 21 nm. On this basis,a classification standard for three types of tight sand reservoirs is proposed. Type I reservoirs are characterized by the movable fluid saturation larger than 40%, the movable oil ratio(ratio of movable oil to total oil) greater than 30% and the starting pressure gradient in the range of 0.3-0.6 MPa/m; Type II reservoirs are characterized by the movable fluid saturation in the range of 10%–40%, the movable oil ratio in the range of 5%–30% and the starting pressure gradient in the range of 0.6–1.0 MPa/m; Type III reservoirs are characterized by the movable fluid saturation less than 10% in general, the movable oil ratio less than 5%, and the starting pressure gradient greater than1.0 MPa/m. The fluid mobility in tight sand reservoirs is mainly affected by diagenesis and sedimentary environment. Reservoirs with depth lower than 2000 m are dominated by type I reservoir, whereas those with greater depth are dominated by type I and II reservoirs.Reservoirs in inner delta-front facies are dominated by type I reservoir, whereas those in outer delta-front facies and shore-shallow lacustrine facies are dominated by type II and III reservoirs. | FENG Jun ZHANG Bowei FENG Zihui WANG Yachun ZHANG Juhe FU Xiaofei SUN Yonghe HUO Qiuli SHAO Hongmei ZENG Huasen QU Bin CHI Huanyuan | 2019 | Petroleum Exploration and Development2019，46，2： | 1 |
| 10 | In vitro crevice corrosion of biodegradable magnesium in different solutions显示文摘Magnesium(Mg)is a promising biomedical metal because of its biodegradability.The crevice between tissue and Mg implant can not be neglected in some implantation sites due to inducing crevice corrosion of Mg.In this paper,a new single mold was designed to build the in vitro experimental setup and four kinds of solutions,i.e.the deionized water(DW),the 0.9 wt.%sodium chloride solution(NaCl),the phosphate buffer saline(PBS)and the modified simulated body fluid(m-SBF)were used to explore necessary factors of crevice corrosion in Mg.It was observed that crevice corrosion in Mg sheets would occur in NaCl and PBS solution under 0.2,0.5 and 0.8 mm crevice thickness.And it was found that there were two necessary factors,i.e.chloride ion and crevice dimension,in crevice corrosion.For the high-purity Mg cannulated screws,crevice corrosion could occur inside tunnel when immersed in PBS. | Bowei Chen Hongliu Wu Ruibang Yi Wenhui Wang Haidong Xu Shaoxiang Zhang Hongzhou Peng Junwei Ma Haomiao Jiang Rui Zan Shuang Qiao Yu Sun Peng Hou Pei Han Jiahua Ni Xiaonong Zhang | 2020 | Journal of Materials Science & Technology2020，52，17： | 0 |
| 11 | Selection of specific nanobodies against peanut allergen through unbiased immunization strategy and the developed immuno-assay显示文摘Peanut allergy is considered to be a major health issue with global effects.To date,no effective curative approach has been applied for the therapy of the anaphylaxis resulting from the peanut allergens.The accurate and effective detection methods for the surveillance of allergens in food are still the primary strategies to avoid allergic diseases.In this study,nanobodies(Nbs)derived from the Heavy-Chain only Antibodies(HCAbs)were selected against the general peanut protein extract through the unbiased strategy to facilitate the development of the sandwich ELISA for the detection and surveillance of peanut allergen contamination.The target antigen of the selected Nb was identified as peanut allergen Ara h 3,and a cross-reaction was observed with the member of Gly 1 from the Ara h 3 family.The applicability of the self-paired Nb P43 on the establishment of the immuno-assay was verified.A sandwich ELISA against peanut allergen was developed,which reached a linear range of 0.2-10.6μg/mL,and a limit of detection of 53.13 ng/mL. | Yaozhong Hu Chuan Zhang Jing Lin Yi Wang Sihao Wu Ying Sun Bowei Zhang Huan Lv Xuemeng Ji Yang Lu Shuo Wang | 2023 | Food Science and Human Wellness2023，12，3： | 0 |
| 12 | Observation of Zeeman splitting effect in a laser-driven coil显示文摘The Zeeman splitting effect is observed in a strong magnetic field generated by a laser-driven coil.The expanding plasma from the coil wire surface is concentrated at the coil center and interacts with the simultaneously generated magnetic field.The Cu I spectral lines at wavelengths of 510.5541,515.3235,and 521.8202 nm are detected and analyzed.The splittings of spectral lines are used to estimate the magnetic field strength at the coil center as∼31.4±15.7 T at a laser intensity of∼5.6310^(15) W/cm^(2),which agrees well with measurements using a B-dot probe.Some other plasma parameters of the central plasma disk are also studied.The temperature is evaluated from the Cu I spectral line intensity ratio,while the electron density is estimated from the Stark broadening effect. | Baojun Zhu Zhe Zhang Chang Liu Dawei Yuan Weiman Jiang Huigang Wei Fang Li Yihang Zhang Bo Han Lei Cheng Shangqing Li Jiayong Zhong Xiaoxia Yuan Bowei Tong Wei Sun Zhiheng Fang Chen Wang Zhiyong Xie Neng Hua Rong Wu Zhanfeng Qiao Guiyun Liang Baoqiang Zhu Jianqiang Zhu Shinsuke Fujioka Yutong Li | 2022 | Matter and Radiation at Extremes2022，7，2： | 0 |
