| 1 | Microstructure, mechanical properties and deformation mechanisms of an as-cast Mg–Zn–Y–Nd–Zr alloy for stent applications显示文摘A new Mg-2Zn-0.2Y -0.5N d-0.4Zr (wt%) alloy designed specially for stent applications has been developed. The as-cast alloy is featured with equiaxed grains with a mean size of about 40 μm and a small am ount of second phase (T phase) distributed discontinuously either at the grain boundaries or inside the grains. This alloy exhibits a tensile elongation of up to 35%, which is much larger than that of most reported other as-cast Mg alloys. The tensile deform ation mechanisms have also been investigated. The results show that, besides basal slip,{10-12} extension twining and non-basal pyramidal slips can also be observed at initial stage and later stage during tensile deform ation, respectively, which are responsible for the good room -tem perature ductility. | Jianfeng Wang Hongbo Zhou Liguo Wang Shijie Zhu Shaokang Guan | 2019 | Journal of Materials Science & Technology2019，35，7： | 9 |
| 2 | Transcriptome analysis of blood stasis syndrome in subjects with hypertension显示文摘OBJECTIVE:To screen for m RNAs associated with blood stasis syndrome and to explore the genetic mechanisms of blood stasis syndrome in hypertension.METHODS:This study involved groups of patients with hypertension and blood stasis,including those with Qi deficiency,Qi stagnation,cold retention and heat retention;as well as hypertensive patients without blood stasis and healthy individuals.Human umbilical vein endothelial cells were co-cultured with the sera of these healthy individuals and patients with blood stasis syndrome.Total RNA was extracted from these cells and assessed by a high-throughput sequencing method(Solexa)and digital gene expression.Differentially expressed genes among these six groups were compared using whole genome sequences,and m RNAs associated with blood stasis syndrome identified.Differences in gene use and gene ontology function were an-alyzed.Genes enriched significantly and their pathways were determined,as were network interactions,and encoded proteins.Gene identities were confirmed by real-time polymerase chain reactions.RESULTS:Compared with cells cultured in sera of the blood stasis groups,those culture in sera of healthy individuals and of the non-blood stasis group showed 11 and 301 differences,respectively in stasis-related genes.Genes identified as differing between the blood stasis and healthy groups included activating transcription factor 4,activating transcription factor 3,DNA-damage inducible transcription factor 3,Tribbles homolog 3,CCAAT/enhancer binding protein-β,and Jun proto-oncogene(JUN).Pathway and protein interaction network analyses showed that these genes were associated with endoplasmic reticulum stress.Cells cultured in sera of patients with blood stasis and Qi deficiency,Qi stagnation,heat retention,and cold retention were compared with cells cultured in sera of patients with the other types blood stasis syndrome.The comparison showed differences in expression of 28,28,34,and 32 specific genes,respectively.CONCLUSION:The pathogenesis of blood stasis syndrome in hypertension is related to endoplasmic reticulum stress and involves the differential expression of the activating transcription factor 4,activating transcription factor 3,DNA-damage inducible transcription factor 3,Tribbles homolog 3,CCAAT/enhancer binding protein-β,and JUN genes. | He Ling Fang Meixia Chen Liguo Zhou Jianhua Yuan Jing Xu Jing Shan Yan Xu Qingyun Xiong Tingting | 2016 | Journal of Traditional Chinese Medicine2016，36，2： | 7 |
| 3 | Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients. | Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang | 2020 | Cancer Biology & Medicine2020，17，1： | 6 |
| 4 | Distributed sensor fault diagnosis for a formation system with unknown constant time delays显示文摘In this paper, a distributed velocity sensor fault diagnosis scheme is presented for a formation of a second-order multi-agent system with unknown constant communication time delays. An existing distributed proportion-derivation(DPD) formation control law is adopted and a delay-independent condition is proposed to guarantee the asymptotical formation stability of the formation system based on the Nyquist stability criterion. Then a distributed fault diagnosis scheme is developed. In each agent, a distributed fault detection residual generator(DFDRG) and a bank of distributed fault isolation residual generators(DFIRGs) are designed based on the closed-loop model of the whole system. Each DFIRG is built up on the basis of a reduced-order unknown input observer(UIO) which is robust to the fault of one neighboring agent. According to the robust relationship between DFIRGs and faults, distributed fault isolation can be achieved. Conditions are presented to guarantee that each agent is able to diagnose faults of itself and its neighbors despite the disturbance of time delays. Finally, outdoor experimental results illustrate the effectiveness of the proposed schemes. | Donghua ZHOU Liguo QIN Xiao HE Rui YAN Ruiliang DENG | 2018 | Science China(Information Sciences)2018，61，11： | 5 |
| 5 | Effective control allocation using hierarchical multi-objective optimization for multi-phase flight显示文摘For different flight phases in an overall flight mission,different control and allocation preferences should be pursued considering lift,drag or maneuverability characteristics.The multi-objective flight control allocation problem for a multi-phase flight mission is studied.For an overall flight mission,different flight phases namely climbing,cruise,maneuver and gliding phases are defined.Firstly,a multi-objective control allocation problem considering drag,lift or control energy preference is constructed.Secondly,considering different control preferences at different flight phases,the analytic hierarchical process method is used to construct a comprehensive performance index from different objectives such as lift or drag preferences.The active set based dynamic programming optimization method is used to solve the real-time optimization problem.For the validation,the Innovative Control Effector(ICE)tailless aircraft nonlinear model and the angular acceleration measurements based adaptive Incremental Backstepping(IBKS)are used to construct the validation platform.Finally,an overall flight mission is simulated to demonstrate the efficiency of the proposed multi-phase and multi-objective flight control allocation method.The results show that the comprehensive performance index for different phases,which are determined from the Analytic Hierarchy Process(AHP)method,can suitably satisfy the preference requirements for different flight phases. | Liguo SUN Qing ZHOU Baoxu JIA Wenqian TAN Hangxu LI | 2020 | Chinese Journal of Aeronautics2020，33，7： | 4 |
| 6 | Design of Eco-friendly Ultra-high Performance Concrete with Supplementary Cementitious Materials and Coarse Aggregate显示文摘Aiming to investigate the mix design of eco-friendly UHPC with supplementary cementitious materials and coarser aggregates, we comprehensively studied the workability, microstructure, porosity, compressive strength, flexural strength, and Young’s modulus of UHPC. Relationship between compressive strength and Young’s modulus was obtained eventually. It is found that the compressive strength, flexural strength, and Young’s modulus of UHPC increase by 19.01%, 10.81%, and 5.99%, respectively, when 40 wt% cement is replaced with supplementary cementitious materials. The relationship between compressive strength and Young’s modulus of UHPC is an exponential form. | 蒋金洋 ZHOU Wenjing CHU Hongyan WANG Fengjuan WANG Liguo FENG Taotao GUO Dong | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，6： | 3 |
| 7 | Blue revolution for food security under carbon neutrality: A case from the water-saving and drought-resistance rice显示文摘The increasing concentration of greenhouse gases(GHGs)in Earth's atmosphere leads to global warming,which further causes a series of climate changes and does great harm to both human society and natural ecosystems.Agricultural GHG emissions,mainly in theform of methane(CH4)and nitrous oxide(N2O),areasignificantsourceofGHGs,accountingfor~14%total global GHGs(Zhang et al.,2022).One major source of agricultural GHGs is CH4 emissions from rice paddies,which is responsiblefor~10%-12%ofhuman-inducedCH4emissions(van Groenigen et al.,2013)and contributes~2.40%to the enhanced global warming effect(Zhang et al.,2022).The global warming potential of GHGs emissions from rice systems is roughly four times higher than either wheat or maize(Linquist et al.,2012). | Hui Xia Xianxian Zhang Yi Liu Junguo Bi Xiaosong Ma Anning Zhang Hongyan Liu Liang Chen Sheng Zhou Huan Gao Kai Xu Haibin Wei Guolan Liu Feiming Wang Hongyang Zhao Xingxing Luo Danping Hou Qiaojun Lou Fangjun Feng Liguo Zhou Shoujun Chen Ming Yan Tianfei Li Mingshou Li LeiWang Zaochang Liu Xinqiao Yu HanweiMei Lijun Luo | 2022 | Molecular Plant2022，15，9： | 3 |
| 8 | Multifunctional succinate additive for flexible perovskite solar cells with more than 23%power-conversion efficiency显示文摘Flexible perovskite solar cells(FPSCs)have emerged as power sources in versatile applications owing to their high-efficiency characteristics,excellent flexibility,and relatively lowcost.Nevertheless,undesired strain in perovskite films greatly impacts the power-conversion efficiency(PCE)and stability of PSCs,particularly in FPSCs.Herein,a novel multifunctional organic salt,methylammonium succinate,which can alleviate strain and reinforce grain boundaries,was incorporated into the perovskite film,leading to relaxed microstrain and a lower defect concentration.As a result,a PCE of 25.4%for rigid PSCs and a record PCE of 23.6%(certified 22.5%)for FPSCs have been achieved.In addition,the corresponding FPSCs exhibited excellent bending durability,maintaining85%of their initial efficiency after bending at a 6 mm radius for 10000 cycles. | Minghao Li Junjie Zhou Liguo Tan Hang Li Yue Liu Chaofan Jiang Yiran Ye Liming Ding Wolfgang Tress Chenyi Yi | 2022 | The Innovation2022，3，6： | 2 |
| 9 | Reverse time migration based on normalized wavefield decomposition imaging condition显示文摘With the increasing complexity of prospecting objectives,reverse time migration( RTM) has attracted more and more attention due to its outstanding imaging quality. RTM is based on two-way wave equation,so it can avoid the limits of angle in traditional one-way wave equation migration,image reverse branch,prism waves and multi-reflected wave precisely and obtain accurate dynamic information. However,the huge demands for storage and computation as well as low frequency noises restrict its wide application. The normalized cross-correlation imaging conditions based on wave field decomposition are derived from traditional cross-correlation imaging condition,and it can eliminate the low-frequency noises effectively and improve the imaging resolution. The practical procedure includes separating source and receiver wave field into one-way components respectively,and conducting cross-correlation imaging condition to the post-separated wave field. In this way,the resolution and precision of the imaging result will be promoted greatly. | YU Jianglong HAN Liguo ZHOU Yan ZHANG Yongsheng | 2016 | Global Geology2016，19，2： | 1 |
| 10 | A biobased flame retardant towards improvement of flame retardancy and mechanical property of ethylene vinyl acetate显示文摘A new biobased flame retardant(MHPA)with remarkable compatibility was synthesized via a facile and low-cost neutralization reaction of magnesium hydroxide(MH)and phytic acid(PA).By blending the prepared MHPA into ethylene vinyl acetate(EVA),the fire retardancy,smoke suppression and mechanical properties of the composites were significantly improved.When 50 wt%of MH was added into EVA matrix,the value of limiting oxygen index(LOI)reached 26.1%.Whereas,when 10 wt%MH in the EVA composites(with initial 50 wt%MH)was replaced by MHPA,the resulted EVA composites had a LOI value of 30.8%,indicating high efficiency of addition of MHPA to improve flame retardancy.Moreover,the heat release rate(HRR)and total smoke production(TSP)of the EVA composites reduced by 54.4%and 27.6%,respectively,suggesting that incorporation of MHPA could effectively hinder rapid degradation of EVA composites during burning process.The fire-retardant mechanism may reside in that the MHPA combined with MH can present the excellent carbonization and expansion effects.This study illustrates that the biobased MHPA has a broad application prospect to develop flame-retardant EVA composites. | Siyi Xu Yue Han Cheng Zhou Jianxi Li Liguo Shen Hongjun Lin | 2023 | Chinese Chemical Letters2023，34，1： | 1 |
| 11 | Engineering hollow core-shell hetero-structure box to induce interfacial charge modulation for promoting bidirectional sulfur conversion in lithium-sulfur batteries显示文摘Severe polysulfide shuttling and sluggish sulfur redox kinetics significantly decrease sulfur utilization and cycling stability in lithium-sulfur batteries(LSBs).Herein,we develop a hollow CoO/CoP-Box core-shell heterostructure as a model and multifunctional catalyst modified on separators to induce interfacial charge modulation and expose more active sites for promoting the adsorption and catalytic conversion ability of sulfur species.Theoretical and experimental findings verify that the in-situ formed core-shell hetero-interface induces the formation of P-Co-O binding and charge redistribution to activate surface O active sites for binding lithium polysulfides(LiPSs)via strong Li-O bonding,thus strongly adsorbing with Li PSs.Meanwhile,the strong Li-O bonding weakens the competing Li-S bonding in LiPSs or Li2S adsorbed on CoO/CoP-Box surface,plus the hollow heterostructure provides abundant active sites and fast electron/Li+transfer,so reducing Li2S nucleation/dissolution activation energy.As expected,LSBs with CoO/CoP-Box modified separator and traditional sulfur/carbon black cathode display a large initial capacity of 1240 mA h g^(-1)and a long cycling stability with 300 cycles(~60.1%capacity retention)at 0.5C.Impressively,the thick sulfur cathode(sulfur loading:5.2 mg cm^(-2))displays a high initial areal capacity of 6.9 mA h cm^(-2).This work verifies a deep mechanism understanding and an effective strategy to induce interfacial charge modulation and enhance active sites for designing efficient dual-directional Li-S catalysts via engineering hollow core-shell hetero-structure. | Weiliang Zhou Xinying Wang Jiongwei Shan Liguo Yue Dongzhen Lu Li Chen Jiacheng Zhang Yunyong Li | 2023 | Journal of Energy Chemistry2023，，5： | 1 |

| 13 | Enhancing THz fingerprint detection on the planar surface of an inverted dielectric metagrating显示文摘Terahertz(THz)molecular fingerprint sensing provides a powerful label-free tool for the detection of traceamount samples.Due to the weak light–matter interaction,various metallic or dielectric metasurfaces have been adopted to enhance fingerprint absorbance signals.However,they suffer from strong background damping or complicated sample coating on patterned surfaces.Here,we propose an inverted dielectric metagrating and enhance the broadband THz fingerprint detection of trace analytes on a planar sensing surface.Enhancement of the broadband signal originates from the effects of evanescent waves at the planar interface,which are excited by multiplexed quasi-bound states in the continuum(quasi-BICs).One can evenly boost the near-field intensities within the analytes by tuning the asymmetry parameter of quasi-BIC modes.The multiplexing mechanism of broadband detection is demonstrated by manipulating the incident angle of excitation waves and thickness of the waveguide layer.Compared to the conventional approach,the THz fingerprint peak value is dramatically elevated,and the largest peak enhancement time is 330.Our work gives a promising way to facilitate the metasensing of the THz fingerprint on a planar surface and will inspire universal THz spectral analysis for trace analytes with different physical states or morphologies. | XUEYING LIU WEI CHEN YONGJIE MA YINONG XIE JUN ZHOU LIGUO ZHU YADONG XU JINFENG ZHU | 2022 | Photonics Research2022，10，12： | 1 |

| 17 | In vitro corrosion properties of HTHEed Mg-Zn-Y-Nd alloy microtubes for stent applications:Influence of second phase particles and crystal orientation显示文摘Magnesium(Mg)alloys are promising materials for cardiovascular stent applications due to their good biocompatibility and biodegradability.However,in vitro and in vivo corrosion tests reveal that Mg alloy stents suffer from a rapid corrosion rate and severe localized corrosion,which is limiting their widespread application.To solve the problem of uneven degradation of stents,a HTHE(long-time and high-temperature heat treatment,large-reduction-ratio hot extrusion)process is used to manufacture Mg-Zn-Y-Nd alloy microtubes in this study.The heat treatment is to dissolve alloying elements and reduce the size of SPPs,and the hot extrusion is to acquire fine-grained and strongly textured microtubes.The microstructural characterization shows that coarse second phases in as-cast alloy are refined and uniformly distributed in matrix of microtubes.After hot extrusion,microtubes show strong texture with basal plain oriented parallel to the longitudinal section(LS).The corrosion testing indicates that severe localized corrosion occurs on the cross section(CS)while localized corrosion is alleviated on the LS.Based on the different corrosion properties of the LS and CS,HTHEed microtubes are promising for solving the problems of rapid corrosion rate and severe localized corrosion of Mg alloy stents. | Peihua Du Di Mei Tsuyoshi Furushima Shijie Zhu Liguo Wang Yifan Zhou Shaokang Guan | 2022 | Journal of Magnesium and Alloys2022，10，5： | 1 |
| 18 | Integrated representation of geospatial data,model,and knowledge for digital twin railway显示文摘The real-time accurate description of all spatial features of railway and their spatiotemporal relationships is a crucial factor in realizing comprehensive management and related decision-making within the entire life cycle of railways.Nevertheless,available spatiotemporal data models mainly use static historical sequence data,which are insufficient to support multi-source heterogeneous real-time sensed data;they lack a systematic depiction of the interactive relationships among multiple feature entities,and are limited to low-level descriptive analysis.Therefore,this study proposes a data-model-knowledge integrated representation data model for a digital twin railway,which explicitly describes the spatiotemporal,and interaction relationships among railway features through a conceptual knowledge graph.This study first analyzes the characteristics of railway features from above ground to underground,and then constructs a conceptual model to clearly describe the complex relationships among railway features.Secondly,a logical model is developed to illustrate the basic data structure.Thirdly,an ontology model is constructed as a basic framework for further deepening the domain knowledge graph.Finally,considering the prevention of landslides as an example,it demonstrates the abundant spatiotemporal relationships among railway related features.The results of this study bring more clear understanding of the complex interactive relationships of railway entities. | Hankan Li Qing Zhu Liguo Zhang Yulin Ding Yongxin Guo Haoyu Wu Qiang Wang Runfang Zhou Mingwei Liu Yan Zhou | 2022 | International Journal of Digital Earth2022，15，1： | 1 |
