| 1 | Efficient Fe(Ⅲ)/Fe(Ⅱ) cycling triggered by MoO2 in Fenton reaction for the degradation of dye molecules and the reduction of Cr(Ⅵ)显示文摘There is a relatively low efficiency of Fe(Ⅲ)/Fe(Ⅱ) conversion cycle and H2 O2 decomposition(<30%) in conventional Fenton process,which further results in a low production efficiency of ·OH and seriously restricts the application of Fenton.Herein,we report that the commercial MoO2 can be used as the cocatalyst in Fenton process to dramatically accelerate the oxidation of Lissamine rhodamine B(L-RhB),where the efficiency of Fe(Ⅲ)/Fe(Ⅱ) cycling is greatly enhanced in the Fenton reaction meanwhile.And the L-RhB solution could be degraded nearly 100% in 1 min in the MoO2 cocatalytic Fenton system under the optimal reaction condition,which is apparently better than that of the conventional Fenton system(~50%).Different from the conventional Fenton reaction where the ’OH plays an important role in the oxidation process,it shows that 1 O2 contributes most in the MoO2 cocatalytic Fenton reaction.However,it is found that the exposed Mo^4+ active sites on the surface of MoO2 powders can greatly promote the rate-limiting step of Fe^3+/Fe^2+ cycle conversion,thus minimizing the dosage of H2 O2(0.400 mmol/L) and Fe^2+(0.105 mmol/L).Interestingly,the MoO2 cocatalytic Fenton system also exhibits a good ability for reducing Cr(Ⅵ) ions,where the reduction ability for Cr(Ⅵ) reaches almost 100% within 2 h.In short,this work shows a new discovery for M002 cocatalytic advanced oxidation processes(AOPs),which devotes a lot to the practical water remediation application. | Bin Shen Chencheng Dong Jiahui Ji Mingyang Xing Jinlong Zhang | 2019 | Chinese Chemical Letters2019，30，12： | 11 |

| 3 | Targeting a novel inducible GPX4 alternative isoform to alleviate ferroptosis and treat metabolic-associated fatty liver disease显示文摘Metabolic-associated fatty liver disease(MAFLD),which is previously known as non-alcoholic fatty liver disease(NAFLD),represents a major health concern worldwide with limited therapy.Here,we provide evidence that ferroptosis,a novel form of regulated cell death characterized by iron-driven lipid peroxidation,was comprehensively activated in liver tissues from MAFLD patients.The canonical-GPX4(cGPX4),which is the most important negative controller of ferroptosis,is downregulated at protein but not mRNA level.Interestingly,a non-canonical GPX4 transcript-variant is induced(inducible-GPX4,iGPX4)in MAFLD condition.The high fat-fructose/sucrose diet(HFFD)and methionine/choline-deficient diet(MCD)-induced MAFLD pathologies,including hepatocellular ballooning,steatohepatitis andfibrosis,were attenuated and aggravated,respectively,in cGPX4-and iGPX4-knockin mice.cGPX4 and iGPX4 isoforms also displayed opposing effects on oxidative stress and ferroptosis in hepatocytes.Knockdown of iGPX4 by siRNA alleviated lipid stress,ferroptosis and cell injury.Mechanistically,the triggered iGPX4 interacts with cGPX4 to facilitate the transformation of cGPX4 from enzymatic-active monomer to enzymatic-inactive oligomers upon lipid stress,and thus promotes ferroptosis.Co-immunoprecipitation and nano LC–MS/MS analyses confirmed the interaction between iGPX4 and cGPX4.Our results reveal a detrimental role of non-canonical GPX4 isoform in ferroptosis,and indicate selectively targeting iGPX4 may be a promising therapeutic strategy for MAFLD. | Jie Tong Dongjie Li Hongbo Meng Diyang Sun Xiuting Lan Min Ni Jiawei Ma Feiyan Zeng Sijia Sun Jiangtao Fu Guoqiang Li Qingxin Ji Guoyan Zhang Qirui Shen Yuanyuan Wang Jiahui Zhu Yi Zhao Xujie Wang Yi Liu Shenxi Ouyang Chunquan Sheng Fuming Shen Pei Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，9： | 3 |
| 4 | Plant multiscale networks:charting plant connectivity by multi-level analysis and imaging techniques显示文摘In multicellular and even single-celled organisms,individual components are interconnected at multiscale levels to produce enormously complex biological networks that help these systems maintain homeostasis for development and environmental adaptation.Systems biology studies initially adopted network analysis to explore how relationships between individual components give rise to complex biological processes.Network analysis has been applied to dissect the complex connectivity of mammalian brains across different scales in time and space in The Human Brain Project.In plant science,network analysis has similarly been applied to study the connectivity of plant components at the molecular,subcellular,cellular,organic,and organism levels.Analysis of these multiscale networks contributes to our understanding of how genotype determines phenotype.In this review,we summarized the theoretical framework of plant multiscale networks and introduced studies investigating plant networks by various experimental and computational modalities.We next discussed the currently available analytic methodologies and multi-level imaging techniques used to map multiscale networks in plants.Finally,we highlighted some of the technical challenges and key questions remaining to be addressed in this emerging field. | Xi Zhang Yi Man Xiaohong Zhuang Jinbo Shen Yi Zhang Yaning Cui Meng Yu Jingjing Xing Guangchao Wang Na Lian Zijian Hu Lingyu Ma Weiwei Shen Shunyao Yang Huimin Xu Jiahui Bian Yanping Jing Xiaojuan Li Ruili Li Tonglin Mao Yuling Jiao Sodmergen Haiyun Ren Jinxing Lin | 2021 | Science China(Life Sciences)2021，64，9： | 3 |

| 6 | BIG1 mediates sepsis-induced lung injury by modulating lipid raft-dependent macrophage inflammatory responses显示文摘Sepsis is a systemic inflammatory response syndrome with high mortality.It has been reported that brefeldin A-inhibited guanine nucleotide-exchange factor 1(BIG1)is involved in the pathogenesis of sepsis.However,the mechanism is not fully elucidated.In the present study,we explored the role of BIG1 in mediating lipid raft-dependent macrophage inflammatory response and its impact on lung injury in murine sepsis.In vitro studies revealed that BIG1 deficiency reduces the upregulation and secretion of tumor necrosis factor alpha(TNF-α),interleukin-6(IL-6),and IL-1β and inhibits the activation of the toll-like receptor 4(TLR4)/myeloid differentiation primary response 88-dependent nuclear factor kappa-B signaling pathway induced by the lipopolysaccha-ride(LPS)treatment.Further experiments revealed that the inhibitory effects of BIG1 deficiency on LPS-induced inflammation are due to the upregulation of adenosine triphosphate-binding cassette transporter A1.This promotes the free-cholesterol efflux from lipid rafts and results in the reduction of lipid raft TLR4 content.The decrease in TLR4 content in lipid raft thereby inhibits the LPS-induced inflammatory response.Furthermore,using the cecal ligation and puncture-induced polymicrobial sepsis mouse model,we found that conditional knockout(cKO)of the myeloid cell BIG1 significantly reduced the serum concentrations of TNF-α,IL-6,and IL-1β,and downregulated their mRNA expressions in the lungs.Pathological analysis confirmed that the BIG1 cKO alleviated the sepsis-induced lung injury.These results revealed the crucial new role of BIG1 in mediating lipid raft-dependent macrophage inflammatory response.Hence,BIG1 may be a potential promising therapeutic target for the treatment of septic lung injury. | Minli Sun Xiaodan Han Di Zhou Jing Zhong Lixin Liu Yirui Wang Jiahui Ni Xiaoyan Shen Chao Liang Hao Fang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，8： | 1 |
| 7 | Stretchable polymer composites with ultrahigh piezoelectric performance显示文摘Flexible piezoelectric materials capable of withstanding large deformation play key roles in flexible electronics.Ferroelectric ceramics with a high piezoelectric coefficient are inherently brittle,whereas polar polymers exhibit a low piezoelectric coefficient.Here we report a highly stretchable/compressible piezoelectric composite composed of ferroelectric ceramic skeleton,elastomer matrix and relaxor ferroelectric-based hybrid at the ceramic/matrix interface as dielectric transition layers,exhibiting a giant piezoelectric coefficient of 250 picometers per volt,high electromechanical coupling factor keff of 65%,ultralow acoustic impedance of 3MRyl and high cyclic stability under 50%compression strain.The superior flexibility and piezoelectric properties are attributed to the electric polarization and mechanical load transfer paths formed by the ceramic skeleton,and dielectric mismatch mitigation between ceramic fillers and elastomer matrix by the dielectric transition layer.The synergistic fusion of ultrahigh piezoelectric properties and superior flexibility in these polymer composites is expected to drive emerging applications in flexible smart electronics. | Tongxiang Tang Zhonghui Shen Jian Wang Shiqi Xu Jiaxi Jiang Jiahui Chang Mengfan Guo Youjun Fan Yao Xiao Zhihao Dong Houbing Huang Xiaoyan Li Yihui Zhang Danyang Wang Long-Qing Chen Ke Wang Shujun Zhang Ce-Wen Nan Yang Shen | 2023 | National Science Review2023，10，8： | 1 |
| 8 | Magnetic anisotropy of Fe films deposited by dc magnetron sputtering under an external magnetic field显示文摘Magnetic Fe films grown on single-crystal Mg O(001) and(011) substrates were prepared by direct current magnetron sputtering. The experimental results showed that by applying an external magnetic field of about 300 Oe to film during deposition, a fourfold cubic magnetic anisotropy on Mg O(001) substrate and a twofold uniaxial magnetic anisotropy on Mg O(011) substrate were generated, compared to the isotropic magnetization of Fe film grown without applying the external magnetic field.Our results suggested that external magnetic field during preparation effectively induced relatively higher surface mobility of sputtered Fe atoms and further promoted the crystallization of Fe film and the enhancement of magnetic anisotropy. | Jiahui Chen Jing Ma Liang Wu Yang Shen Ce-Wen Nan | 2015 | Science Bulletin2015，60，13： | 1 |
| 9 | Multi-scale Analysis of the Relationships between Solar Activity, CO_(2) and Global Surface Temperature显示文摘To reveal whether the dynamics of solar activity precede those of global temperature, especially in terms of global warming, the relationship between total solar irradiance(TSI), which is treated as a proxy of solar activity, and global surface temperature(GST) is investigated in the frequency domain using wavelet coherence. The results suggest that the effect of TSI on GST is mainly reflected on the characteristic scale around 22 yr, and variations in TSI lead to changes in GST with some delay effect as shown by the phase difference arrows. However, this implicated relationship has been perturbed by excessive CO_(2) emissions since 1960. Through the combination of co-integration analysis and wavelet coherence, the hidden relationship between TSI and GST has been uncovered without the CO_(2) effect and the results further indicate that TSI has a positive effect on GST at the characteristic scale around 22 yr with a 3 yr lead. | Zhen Li Lijun Chang Jiahui Lou Yi Shen Haoming Yan | 2022 | Research in Astronomy and Astrophysics2022，22，9： | 0 |
| 10 | Spatiotemporal characteristics of seed rain and soil seed bank of artificial Caragana korshinskii Kom. forest in the Tengger Desert, China显示文摘Vegetation restoration and reconstruction are effective approaches to desertification control and achieving social and economic sustainability in desert areas.However,the self-succession ability of native plants during the later periods of vegetation restoration remains unclear.Therefore,this study was conducted to bridge the knowledge gap by investigating the regeneration dynamics of artificial forest under natural conditions.The information of seed rain and soil seed bank was collected and quantified from an artificial Caragana korshinskii Kom.forest in the Tengger Desert,China.The germination tests were conducted in a laboratory setting.The analysis of species quantity and diversity in seed rain and soil seed bank was conducted to assess the impact of different durations of sand fixation(60,40,and 20 a)on the progress of vegetation restoration and ecological conditions in artificial C.korshinskii forest.The results showed that the top three dominant plant species in seed rain were Echinops gmelinii Turcz.,Eragrostis minor Host.,and Agropyron mongolicum Keng.,and the top three dominant plant species in soil seed bank were E.minor,Chloris virgata Sw.,and E.gmelinii.As restoration period increased,the density of seed rain and soil seed bank increased first and then decreased.While for species richness,as restoration period increased,it gradually increased in seed rain but decreased in soil seed bank.There was a positive correlation between seed rain density and soil seed bank density among all the three restoration periods.The species similarity between seed rain or soil seed bank and aboveground vegetation decreased with the extension of restoration period.The shape of the seeds,specifically those with external appendages such as spines and crown hair,clearly had an effect on their dispersal,then resulting in lower seed density in soil seed bank.In addition,precipitation was a crucial factor in promoting rapid germination,also resulting in lower seed density in soil seed bank.Our findings provide valuable insights for guiding future interventions during the later periods of artificial C.korshinskii forest,such as sowing and restoration efforts using unmanned aerial vehicles. | SHEN Jianxiang WANG Xin WANG Lei WANG Jiahui QU Wenjie ZHANG Xue CHANG Xuanxuan YANG Xinguo CHEN Lin QIN Weichun ZHANG Bo NIU Jinshuai | 2024 | Journal of Arid Land2024，16，4： | 0 |
| 11 | Issues and strategies of cathode materials for mild aqueous static zinc-ion batteries显示文摘Researchers prefer mild aqueous static zinc-ion batteries(ASZIBs)for their distinct benefits of excellent safety,abundant zinc resources,low cost,and high energy density.However,at the moment there are some issues with the cathode materials of mild ASZIBs,including dissolution,by-products,poor conductivity,and a contentious energy storage system.Consequently,there are numerous difficulties in the development of high-performance mild ASZIBs cathode materials.This overview examines the mechanisms for storing energy and the de-velopments in inorganic,organic,and other novel cathode materials that have emerged in recent years.At the same time,three solutions—structural engineering,interface engineering,and reaction pathway engineering—as well as the difficulties now faced by the cathode materials of mild ASZIBs are forcefully introduced.Finally,a prospect is made regarding the evolution of cathode materials in the future. | Wei Zhong Jiahui Zhang Zongmiao Li Zeyu Shen Shichao Zhang Xinyang Wang Yingying Lu | 2023 | Green Chemical Engineering2023，4，3： | 0 |
| 12 | Platycodon grandiflorus polysaccharide regulates colonic immunity through mesenteric lymphatic circulation to attenuate ulcerative colitis显示文摘Platycodon grandiflorus polysaccharide(PGP)is one of the main components of P.grandiflorus,but the mechanism of its anti-inflammatory effect has not been fully elucidated.The aim of this study was to evaluate the therapeutic effect of PGP on mice with dextran sodium sulfate(DSS)-induced ulcerative colitis(UC)and explore the underlying mechanisms.The results showed that PGP treatment inhibited the weight loss of DSS-induced UC mice,increased colon length,and reduced DAI,spleen index,and pathological damage within the colon.PGP also reduced the levels of pro-inflammatory cytokines and inhibited the enhancement of oxidative stress and MPO activity.Meanwhile,PGP restored the levels of Th1,Th2,Th17,and Treg cell-related cytokines and transcription factors in the colon to regulate colonic immunity.Further studies revealed that PGP regulated the balance of colonic immune cells through mesenteric lymphatic circulation.Taken together,PGP exerts anti-inflammatory and anti-oxidant effect and regulates colonic immunity to attenuate DSS-induced UC through mesenteric lymphatic circulation. | LIU Yang DONG Yahui SHEN Wei DU Jiahui SUN Quanwei YANG Ye YIN Denke | 2023 | Chinese Journal of Natural Medicines2023，21，4： | 0 |
| 13 | Seawater temperature and salinity sensing based on in-fiber Michelson-Fabry-Perrot hybrid interferometer employing frequency domain decomposition method显示文摘We propose an in-fiber Michelson-Fabry-Perrot(M-FP)hybrid interferometer for the simultaneous measurement of seawater temperature and salinity.The sensor head consists of two parallel hetero Fabry-Perot(FP)cavities fabricated on the end face of the twin core fiber(TCF).A fiber fusion taper is used to split and recouple the light in the two cores.In this case,the Vernier effect can be obtained which can greatly enhance the sensitivity and solve the problem of temperature cross-sensitivity.Different from the traditional demodulation method based on envelop detection,we employed frequency domain decomposition method(FDDM)to demodulate the sensing signal.The simulation results indicate that the proposed sensor has high sensitivity to salinity and temperature.Thanks to the merits of high sensitivity,ease of fabrication and small footprint,the proposed seawater temperature and salinity sensor would have potential applications in marine science,food industry and ocean ranching. | WANG Jiahui WEI Xian ZHU Yan SHEN Yue PANG Lipeng DUAN Shaoxiang | 2024 | Optoelectronics Letters2024，20，2： | 0 |
| 14 | The interaction between the nervous system and the stomatognathic system: from development to diseases显示文摘The crosstalk between the nerve and stomatognathic systems plays a more important role in organismal health than previously appreciated with the presence of emerging concept of the“brain-oral axis”.A deeper understanding of the intricate interaction between the nervous system and the stomatognathic system is warranted,considering their significant developmental homology and anatomical proximity,and the more complex innervation of the jawbone compared to other skeletons.In this review,we provide an in-depth look at studies concerning neurodevelopment,craniofacial development,and congenital anomalies that occur when the two systems develop abnormally.It summarizes the cross-regulation between nerves and jawbones and the effects of various states of the jawbone on intrabony nerve distribution.Diseases closely related to both the nervous system and the stomatognathic system are divided into craniofacial diseases caused by neurological illnesses,and neurological diseases caused by an aberrant stomatognathic system.The two-way relationships between common diseases,such as periodontitis and neurodegenerative disorders,and depression and oral diseases were also discussed.This review provides valuable insights into novel strategies for neuro-skeletal tissue engineering and early prevention and treatment of orofacial and neurological diseases. | Yuzhu Wu Yanhua Lan Jiajie Mao Jiahui Shen Ting Kang Zhijian Xie | 2023 | International Journal of Oral Science2023，15，3： | 0 |
| 15 | Phenotype and metabolism alterations in PCB-degrading Rhodococcus biphenylivorans TG9^(T) under acid stress显示文摘Environmental acidification impairs microorganism diversity and their functions on substance transformation.Rhodococcus is a ubiquitously distributed genus for contaminant detoxification in the environment,and it can also adapt a certain range of pH.This work interpreted the acid responses from both phenotype and metabolism in strain Rhodococcus biphenylivorans TG9^(T)(TG9)induced at pH 3.The phenotype alterations were described with the number of culturable and viable cells,intracellular ATP concentrations,cell shape and entocyte,degradation efficiency of polychlorinated biphenyl(PCB)31 and biphenyl.The number of culturable cells maintained rather stable within the first 10 days,even though the other phenotypes had noticeable alterations,indicating that TG9 possesses certain capacities to survive under acid stress.The metabolism responses were interpreted based on transcription analyses with four treatments including log phase(LP),acid-induced(PER),early recovery after removing acid(RE)and later recovery(REL).With the overview on the expression regulations among the 4 treatments,the RE sample presented more upregulated and less downregulated genes,suggesting that its metabolism was somehow more active after recovering from acid stress.In addition,the response mechanism was interpreted on 10 individual metabolism pathways mainly covering protein modification,antioxidation,antipermeability,H+consumption,neutralization and extrusion.Furthermore,the transcription variations were verified with RT-qPCR on 8 genes with 24-hr,48-hr and 72-hr acid treatment.Taken together,TG9 possesses comprehensive metabolism strategies defending against acid stress.Consequently,a model was built to provide an integrate insight to understand the acid resistance/tolerance metabolisms in microorganisms. | Aili Li Jiahui Fan Yangyang Jia Xianjin Tang Jingwen Chen Chaofeng Shen | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 16 | Integrated Photothermal Nanoreactors for Effi cient Hydrogenation of CO_(2)显示文摘To alleviate the energy crisis and global warming,photothermal catalysis is an attractive way to effi ciently convert CO_(2)and renewable H_(2) into value-added fuels and chemicals.However,the catalytic performance is usually restricted by the trade-off between the dispersity and light absorption property of metal catalysts.Here we demonstrate a simple SiO 2-protected metal-organic framework pyrolysis strategy to fabricate a new type of integrated photothermal nanoreactor with a comparatively high metal loading,dispersity,and stability.The core-satellite structured Co@SiO_(2)exhibits strong sunlight-absorptive abil-ity and excellent catalytic activity in CO_(2)hydrogenation,which is ascribed to the functional separation of diff erent sizes of Co nanoparticles.Large-sized plasmonic Co nanoparticles are mainly responsible for the light absorption and conversion to heat(nanoheaters),whereas small-sized Co nanoparticles with high intrinsic activities are responsible for the catalysis(nanoreactors).This study provides a new concept for designing effi cient photothermal catalytic materials. | Jiahui Shen Rui Tang Zhiyi Wu Xiao Wang Mingyu Chu Mujin Cai Chengcheng Zhang Liang Zhang Kui Yin Le He Chaoran Li | 2022 | Transactions of Tianjin University2022，28，4： | 0 |

We also assign the πg7/2 [νh11/2]2 configuration with an oblate shape for one of bands in 129La. | WANG Zixing SHEN Shuifa SHI Shuanghui GU Jiahui LIU Jingyi ZHU Zhiyuan (Shanghai Institute of Nuclear Research, the Chinese Academy of Sciences, Shanghai 201800) | 1999 | Nuclear Science and Techniques1999，10，3： | 0 |
| 18 | Synthesis of a Fully Biobased Polyfunctional Vinyl Oligomer and Their UV Cured Films Prepared via Thiol-ene Coupling显示文摘In this paper,a fully bio-based vinyl oligomer with high functionalities was successfully prepared from rapeseed oil by three modification steps:epoxidation of rapeseed oil,solvent-free and catalyst-free ring opening by 10-undecylenic acid followed by esterification with 10-undecenoyl chloride.Then,the renewable polymers were prepared by photo-polymerization of these modified vegetable oils with typical thiol monomers:pentaerythritol tetrakis(3-mercaptopropionate),pentaerythritol tris(3-mercaptopropionate)and 1,2-ethanedithiol.The synthesis of the vinyl oligomer was monitored by nuclear magnetic resonance and Fourier-transform infrared spectroscopy.The average number of the carbon-carbon double bonds of the resulting vinyl oligomer is high to be 7.2.The kinetic of thiol-ene photo-polymerization of vegetable oil-based vinyl oligomer was studied by FTIR-ATR analyses.In addition,the thermo-physical properties,thermal stability and solvent resistance of these UV cured films were characterized.The polymers from 1,2-ethanedithiol exhibit higher gel content,storage modulus and glass transition temperature than those from other thiol monomers due to the high crosslinking densities of the resulting polymers.All polymers show excellent thermal stability up to 290oC.The resulting polymers exhibit thermo-physical properties,excellent water resistance and thermals stability,which is promising to find application in coatings and adhesives. | Changqing Fu Jiahui Wang Lie Chen Liang Shen | 2019 | Journal of Renewable Materials2019，7，8： | 0 |
| 19 | DNMT3A reads and connects histone H3K36me2 to DNA methylation显示文摘Dear Editor,DNA methylation at the 5-position of cytosine(5mC)is a crucial epigenetic mark in regulating biological processes including gene silencing,gene imprinting,and X chromo-some inactivation(Jaenisch and Bird,2003;Smith and Meissner,2013).Human genome encodes three DNA methyltransferases,DNMT1,DNMT3A and DNMT3B to catalyze 5mC.Although not tightly restricted,DNMT1 is thought to maintain the established pattern of 5mC throughout DNA replication,while DNMT3A and DNMT3B are largely responsible for the de novo establishment of 5mC.It has long been questioned how de novo DNA 5mC patterns are established in different genomic regions and whether histone modifications crosstalk to the process.Until recently,it was reported that through recognition of histone H3K36me3 mark,DNMT3B plays a dominant role in medi-ating DNA 5mC in the genic region undergoing active tran-scription(Baubec et al.,2015;Neri et al,2017).However,5mC occurs at both intergenic and genic regions,while H3K36me3 is largely absent in the intergenic regions,indi-cating that the intergenic 5mC may be mediated through diferent mechanisms. | Wenqi Xu Jiahui Li Bowen Rong Bin Zhao Mei Wang Ruofei Dai Qilong Chen Hang Liu Zhongkai Gu Shuxian Liu Rui Guo Hongjie Shen Feizhen Wu Fei Lan | 2020 | Protein & Cell2020，11，2： | 0 |
| 20 | Event-triggered model-free adaptive control for a class of surface vessels with time-delay and external disturbance via state observer显示文摘This paper provides an improved model-free adaptive control(IMFAC)strategy for solving the surface vessel trajectory tracking issue with time delay and restricted disturbance.Firstly,the original nonlinear time-delay system is transformed into a structure consisting of an unknown residual term and a parameter term with control inputs using a local compact form dynamic linearization(local-CFDL).To take advantage of the resulting structure,use a discrete-time extended state observer(DESO)to estimate the unknown residual factor.Then,according to the study,the inclusion of a time delay has no effect on the linearization structure,and an improved control approach is provided,in which DESO is used to adjust for uncertainties.Furthermore,a DESO-based event-triggered model-free adaptive control(ET-DESO-MFAC)is established by designing event-triggered conditions to assure Lyapunov stability.Only when the system’s indicator fulfills the provided event-triggered condition will the control input signal be updated;otherwise,the control input will stay the same as it is at the last trigger moment.A coordinate compensation approach is developed to reduce the steady-state inaccuracy of trajectory tracking.Finally,simulation experiments are used to assess the effectiveness of the proposed technique for trajectory tracking. | CHEN Hua SHEN Chao HUANG Jiahui CAO Yuhan | 2023 | Journal of Systems Engineering and Electronics2023，34，3： | 0 |
