| 1 | Promotion of spinosad biosynthesis by chromosomal integration of the Vitreoscilla hemoglobin gene in Saccharopolyspora spinosa显示文摘To promote spinosad biosynthesis by improving the limited oxygen supply during high-density fermentation of Saccharopolyspora spinosa, the open reading frame of the Vitreoscilla hemoglobin gene was placed under the control of the promoter for the erythromycin resistance gene by splicing using overlapping extension PCR. This was cloned into the integrating vector pSET152, yielding the Vitreoscilla hemoglobin gene expression plasmid pSET152EVHB. This was then introduced into S. spinosa SP06081 by conjugal transfer, and integrated into the chromosome by site-specific recombination at the integration site ΦC31 on pSET152EVHB. The resultant conjugant, S. spinosa S078-1101, was genetically stable. The integration was further confirmed by PCR and Southern blotting analysis. A carbon monoxide differential spectrum assay showed that active Vitreoscilla hemoglobin was successfully expressed in S. spinosa S078-1101. Fermentation results revealed that expression of the Vitreoscilla hemoglobin gene significantly promoted spinosad biosynthesis under normal oxygen and moderately oxygen-limiting conditions (P<0.01). These findings demonstrate that integrating expression of the Vitreoscilla hemoglobin gene improves oxygen uptake and is an effective means for the genetic improvement of S. spinosa fermentation. | LUO YuShuang KOU XiaoXiao DING XueZhi HU ShengBiao TANG Ying LI WenPing HUANG Fan YANG Qi CHEN HanNa XIA LiQiu | 2012 | Science China(Life Sciences)2012,55,2: | 14 |
| 2 | Recent progress for hydrogen production by photocatalytic natural or simulated seawater splitting显示文摘Solar energy is an inexhaustible renewable energy source.Among the various methods for solar energy conversion,photocatalytic hydrogen(H2)production is considered as one of the most promising ways.Since Fujishima pioneered this field in 1972,photocatalytic water splitting to produce H2 has received widespread attention.Up to now,abundant semiconductor materials have been explored as photocatalysts for pure water splitting to produce H2.However,photocatalytic seawater splitting is more in line with the concept of sustainable development,which can greatly alleviate the problem of limited freshwater resource.At present,only few studies have focused on the process of H2 production by photocatalytic seawater splitting due to the complex composition of seawater and lack of suitable photocatalysts.In this review,we outline the most recent advances in photocatalytic seawater splitting.In particular,we introduce the H2 production photocatalysts,underlying mechanism of ions in seawater on photocatalytic seawater splitting,current challenges and future potential advances for this exciting field. | Jining Zhang Wenping Hu Shuang Cao Lingyu Piao | 2020 | Nano Research2020,13,9: | 10 |
| 3 | Recent Advances in Interface Engineering for Electrocatalytic CO_(2) Reduction Reaction显示文摘Electrocatalytic CO_(2) reduction reaction(CO_(2) RR) can store and transform the intermittent renewable energy in the form of chemical energy for industrial production of chemicals and fuels,which can dramatically reduce CO_(2) emission and contribute to carbon-neutral cycle. E cient electrocatalytic reduction of chemically inert CO_(2) is challenging from thermodynamic and kinetic points of view. Therefore,low-cost,highly e cient,and readily available electrocatalysts have been the focus for promoting the conversion of CO_(2). Very recently,interface engineering has been considered as a highly e ective strategy to modulate the electrocatalytic performance through electronic and/or structural modulation,regulations of electron/proton/mass/intermediates,and the control of local reactant concentration,thereby achieving desirable reaction pathway,inhibiting competing hydrogen generation,breaking binding-energy scaling relations of intermediates,and promoting CO_(2) mass transfer. In this review,we aim to provide a comprehensive overview of current developments in interface engineering for CO_(2) RR from both a theoretical and experimental stand-point,involving interfaces between metal and metal,metal and metal oxide,metal and nonmetal,metal oxide and metal oxide,organic molecules and inorganic materials,electrode and electrolyte,molecular catalysts and electrode,etc. Finally,the opportunities and challenges of interface engineering for CO_(2) RR are proposed. | Junjun Li Sulaiman Umar Abbas Haiqing Wang Zhicheng Zhang Wenping Hu | 2021 | Nano-Micro Letters2021,13,12: | 9 |
| 4 | A Brief Introduction to BNU-HESM1.0 and Its Earth Surface Temperature Simulations显示文摘Integrated assessment models and coupled earth system models both have their limitations in understanding the interactions between human activity and the physical earth system. In this paper,a new human–earth system model,BNUHESM1.0,constructed by combining the economic and climate damage components of the Dynamic Integrated Model of Climate Change and Economy to the BNU-ESM model,is introduced. The ability of BNU-HESM1.0 in simulating the global CO2 concentration and surface temperature is also evaluated. We find that,compared to observation,BNU-HESM1.0underestimates the global CO2 concentration and its rising trend during 1965–2005,due to the uncertainty in the economic components. However,the surface temperature simulated by BNU-HESM1.0 is much closer to observation,resulting from the overestimates of surface temperature by the original BNU-ESM model. The uncertainty of BNU-ESM falls within the range of present earth system uncertainty,so it is the economic and climate damage component of BNU-HESM1.0 that needs to be improved through further study. However,the main purpose of this paper is to introduce a new approach to investigate the complex relationship between human activity and the earth system. It is hoped that it will inspire further ideas that prove valuable in guiding human activities appropriate for a sustainable future climate. | YANG Shili DONG Wenjie CHOU Jieming FENG Jinming YAN Xiaodong WEI Zhigang YUAN Wenping GUO Yan TANG Yanli HU Jiacong | 2015 | Advances in Atmospheric Sciences2015,32,12: | 8 |
| 5 | Monolayer organic field-effect transistors显示文摘Monolayer organic field-effect transistors(OFETs) are attracting worldwide interest in device physics and novel applications due to their ultrathin active layer for two-dimensional charge transport. The monolayer films are generally prepared by thermal evaporation, the Langmuir technique or self-assembly process, etc., but their electrical performance is relatively lower than corresponding thick films. From 2011, the performance of monolayer OFETs has been boosted by using the monolayer molecular crystals(MMCs) as active channels, which opened up a new era for monolayer OFETs. In this review, recent progress of monolayer OFETs, including the preparation of monolayer films, their OFET performance and applications are summarized.Finally, perspectives of monolayer OFETs in the near future are also discussed. | Jie Liu Lang Jiang Wenping Hu Yunqi Liu Daoben Zhu | 2019 | Science China Chemistry2019,62,3: | 7 |

| 7 | Vertical‐organic‐nanocrystal‐arrays for crossbar memristors with tuning switching dynamics toward neuromorphic computing显示文摘Memristors proposed by Leon Chua provide a new type of memory device for novel neuromorphic computing applications.However,the approaching of distinct multi‐intermediate states for tunable switching dynamics,the con-trolling of conducting filaments(CFs)toward high device repeatability and reproducibility,and the ability for large‐scale preparation devices,remain full of challenges.Here,we show that vertical‐organic‐nanocrystal‐arrays(VONAs)could make a way toward the challenges.The perfect one‐dimensional structure of the VONAs could confine the CFs accurately with fine‐tune resistance states in a broad range of 103 ratios.The availability of large‐area VONAs makes the fabrication of large‐area crossbar memristor arrays facilely,and the analog switching characteristic of the memristors is to effectively imitate different kinds of synaptic plasticity,indicating their great potential in future applications. | Fangxu Yang Lingjie Sun Qingxi Duan Huanli Dong Zhaokun Jing Yuchao Yang Rongjin Li Xiaotao Zhang Wenping Hu Leon Chua | 2021 | SmartMat2021,2,1: | 5 |
| 8 | Tandem catalysis in electrochemical CO_(2) reduction reaction显示文摘Electrochemical CO_(2) reduction reaction(CO_(2)RR)is an attractive pathway for closing the anthropogenic carbon cycle and storing intermittent renewable energy by converting CO_(2) to valuable chemicals and fuels.The production of highly reduced carbon compounds beyond CO and formate,such as hydrocarbon and oxygenate products with higher energy density,is particularly desirable for practical applications.However,the productivity towards highly reduced chemicals is typically limited by high overpotential and poor selectivity due to the multiple electron-proton transfer steps.Tandem catalysis,which is extensively utilized by nature for producing biological macromolecules with multiple enzymes via coupled reaction steps,represents a promising strategy for enhancing the CO_(2)RR performance.Improving the efficiency of CO_(2)RR via tandem catalysis has recently emerged as an exciting research frontier and achieved significant advances.Here we describe the general principles and also considerations for designing tandem catalysis for CO_(2)RR.Recent advances in constructing tandem catalysts,mainly including bimetallic alloy nanostructures,bimetallic heterostructures,bimetallic core-shell nanostructures,bimetallic mixture catalysts,metal-metal organic framework(MOF)and metal-metallic complexes,metal-nonmetal hybrid nanomaterials and copper-free hybrid nanomaterials for boosting the CO_(2)RR performance are systematically summarized.The study of tandem catalysis for CO_(2)RR is still at the early stage,and future research challenges and opportunities are also discussed. | Yating Zhu Xiaoya Cui Huiling Liu Zhenguo Guo Yanfeng Dang Zhanxi Fan Zhicheng Zhang Wenping Hu | 2021 | Nano Research2021,14,12: | 5 |

| 10 | Surface nanostructures orienting self-protection of an orthodontic nickel-titanium shape memory alloys wire显示文摘Shape memory alloys (SMA) have been applied to a wide variety of applications in a number of different fields such as aeronautical applications, sensors/actuators, medical sciences as well as orthodontics. It is a hot topic to enhance the anti-corrosion ability of orthodontic wires for clinical applications. In this letter, a very nice fractal structure, micro-domains with identical nanometer sized grooves, was ob- tained on the surfaces of the orthodontic wires with an oxygen plasma and acid corrosion. The concave parts of the grooves were dominated by titanium and convex parts were the same as the bulk wires. The micro-nano fractal structure generated a hydrophobic surface with the largest contact angle to water being about 157°. The titanium dominated nanolayer and the hydrophobicity of the surface resulted in jointly the great improvement of the anti-corrosion ability of the orthodontic wires. Because the fractal structures of the wires were formed automatically when they immersed in acidic environment, hence, the self-protection of the oxygen plasma-treated orthodontic wires in acidic environment indicates their potential applications in orthodontics, and should be also inspirable for other applications of SMA materials. | NIE Qiong JI ZhuoYu LIN JiuXiang HU WenPing | 2007 | Chinese Science Bulletin2007,52,21: | 4 |
| 11 | Molecular-scale integrated multi-functions for organic lightemitting transistors显示文摘Organic light-mitting transistors(OLETs)integrate the functions of light-emitting diodes and field-effect transistors into a unique device,opening a new door for optoelectronics.However,there is still a challenge due to the absence of high quality organic semiconductors for OLETs.Herein,we reported a novel molecule 2,6-di(anthracen-2-yl)naphthalene(2,6-DAN),which exhibited mobility of up to 19 cm2:V'-s'and an absolute fluorescence quantum yield of 37.09%,which are good values for organic semiconductors.Moreover,OLETs based on 2,6-DAN single crystals showed bright yellowish-green emission and well-balanced ambipolar charge transport.The excellent ratio of hole to electron mobilty can reach up to 0.86,which is superior to most single component OL ETs in typical device configurations reported so far. | Lei Zheng Jinfeng Li Ke Zhou Xixia Yu Xiaotao Zhang Huanli Dong Wenping Hu | 2020 | Nano Research2020,13,7: | 4 |
| 12 | Recent advances in carbon-based materials for electrochemical CO_(2) reduction reaction显示文摘The increase of atmospheric CO_(2)concentration has caused many environmental issues.Electrochemi-cal CO_(2)reduction reaction(CO_(2)RR)has been considered as a promising strategy to mitigate these chal-lenges.The electrocatalysts with a low overpotential,high Faradaic efficiency,and excellent selectivity are of great significance for the CO_(2)RR.Carbon-based materials including metal-free carbon catalysts and metal-based carbon catalysts have shown great potential in the CO_(2)RR,owing to the tailorable porous structures,abundant natural resources,resistance to acids and bases,high-temperature stability,and en-vironmental friendliness.In this review,various carbon materials including graphene,carbon nanotubes,quantum dots,porous carbon,and MOF-derived catalysts,etc.,for the CO_(2)RR have been summarized.Particularly,recent progress in terms of the mechanism and pathway of CO_(2)conversion has been com-prehensively reviewed.Finally,the opportunities and challenges of carbon-based electrocatalysts for the CO_(2)RR are proposed. | Zengqiang Gao Junjun Li Zhicheng Zhang Wenping Hu | 2022 | Chinese Chemical Letters2022,33,5: | 4 |
| 13 | Expression,structure and function analysis of the sperm-oocyte fusion genes Juno and Izumo1 in sheep(Ovis aries)显示文摘Background:JUNO and IZUMO1 are the first receptor-ligand protein pairs discovered to be essential for spermoocyte fusion;their interaction is indispensable for fertilization.Methods:PCR was used to clone the full-length DNA sequence of the Juno gene in sheep.The single nucleotide polymorphism(SNP)loci of Juno were genotyped by Sequenom MassARRAY®.PCR combined with rapid amplification of cDNA Ends were used to clone the full-length cDNA sequence of Juno and Izumo1.Reverse transcriptase-PCR(RT-PCR)and real time-quantitative-PCR(RT-qPCR)were used to analyze the genes’expression in tissues of sheep,and single cell RNA-seq was used to analyze the genes’expression in oocytes,granulosa cells and follicular theca of polytocous and monotocous Small Tail Han ewes.Bioinformatics was used to analyze advanced structure and phylogeny of JUNO and IZUMO1 proteins.Results:The full-length DNA sequence of the Juno gene in sheep was cloned and nine SNPs were screened.We found a significant association between the g.848253 C>A locus of Juno and litter size of Small Tail Han sheep(P<0.05).The full-length cDNA sequence of Juno and Izumo1 genes from Small Tail Han sheep were obtained.We found a new segment of the Izumo1 CDS consisting of 35 bp,and we confirmed the Izumo1 gene has 9 exons,not 8.RT-qPCR showed that Juno and Izumo1 genes were highly expressed in ovarian and testicular tissues,respectively(P<0.01).Single cell RNA-seq showed Juno was specifically expressed in oocytes,but not in granulosa cells or follicular theca,while Izumo1 displayed little to no expression in all three cell types.There was no difference in expression of the Juno gene in oocyte and ovarian tissue in sheep with different litter sizes,indicating expression of Juno is not related to litter size traits.Bioinformatic analysis revealed the g.848253 C>A locus of Juno results in a nonconservative missense point mutation leading to a change from Phe to Leu at position 219 in the amino acid sequence.Conclusions:For the first time,this study systematically analyzed the expression,structure and function of Juno and Izumo1 genes and their encoded proteins in Small Tail Han sheep,providing the basis for future studies of the regulatory mechanisms of Juno and Izumo1 genes. | Wenping Hu Xinlong Dong Zhilong Tian Zhuangbiao Zhang Jishun Tang Benmeng Liang Qiuyue Liu Mingxing Chu | 2021 | Journal of Animal Science and Biotechnology2021,12,3: | 3 |
| 14 | Using SSR Marker to Trace Chinese Shrimp Fenneropenaeus chinensis Released in Natural Sea-A Feasible Strategy for Assessment of Release Effect in Natural Resources Recovery Program显示文摘Enhancement release has been proven effective in natural resources recovery of Chinese shrimp Fenneropenaeus chinensis in the last several decades in China, however, to assess the effectiveness of enhancement release, we still need to develop a high-efficient and easy-operational method to replace those physical-tagging release method with labor intensive, size-and number-limited. In the present study, single(with maternal known) parentage identification using eight simple sequence repeat(SSR) markers genotype fingerprint was used to trace Chinese shrimp released in Bohai Bay in 2013. A total of 884 shrimp spawners were collected from two hatcheries in Tianjin City respectively after enhancement release of shrimp larvae in May 2013. A total of 844 shrimp samples were recaptured around the release location approximately 4 months after the shrimp larvae were released into the natural sea. Genotype data of 8 SSR loci of the 1,726 samples were used for maternal-offspring parentage identification using CEervus 3.0 software. The allele number in each locus ranged from 8 to 68 with an average value of 33.25, which produced the cumulative exclusion probability with one parent known of all these sight loci up to 99%. Among the 844 recaptured shrimp samples, 448(♂:♀=212:232, gender information was lost for 4 samples) were successfully traced to their 337 maternal parents using a logarithm of odds(LOD) > 3.0 threshold. Among these 337 maternal parents, 253 had a single offspring, 62 had two offspring, 18 had three offspring, 3 had four offspring, and 1 had five offspring. For the first time, a large number of released shrimp were identified from recapture samples, and this study showed that it is possible to trace all released Chinese shrimp without using any type of physical tag in enhancement release activities. This not only means more precise recapture ratio assessment than ever expected, but also this method demonstrates an effective method for large-scale hatchery release as well as for organisms used in hatchery enhancement which are not suitable for physical tagging. | WANG Weiji WANG Mosang XIAO Guangxia HU Yulong SONG Wenping KONG Jie JIN Xianshi | 2018 | 渔业科学进展2018,39,1: | 3 |

| 16 | Progress on major genes for high fecundity in ewes显示文摘The existence of major genes affecting fecundity in sheep flocks throughout the world has been demonstrated.Three major genes whose mutations can increase ovulation rate have been discovered,and all related to the transforming growth factorβ(TGF-β)superfamily.The mutant FecB of bone morphogenetic protein receptor 1B(BMPR1B)has an additive effect on ovulation rate.Six mutations(Fec^(XI),Fec^(XH),Fec^(XG),Fec^(XB),Fec^(XL),Fec^(XR))of bone morphogenetic protein 15(BMP15)related with fertility have been identified that share the same mechanism.All the mutants can increase ovulation rate in heterozygotes and cause complete sterility in homozygotes.Homozygous ewes with two new mutations(FecX^(Gr),FecX^(O))of BMP15 had increased ovulation rate without causing sterility.There are five mutations in growth differentiation factor 9(GDF9)associated with sheep prolificacy where FecG^(E) and FecG^(F) have additive an effect on ovulation rate and litter size.The newly identifiedβ-1,4-N-acetylgalactosaminyltransferase 2(B4GALNT2)gene of FecL is proposed as a new mechanism of ovulation rate regulation in sheep.Woodlands is an X-linked maternally imprinted gene which increases ovulation rate.In addition,several putative major genes need to be verified.This review is focused on the identification of the mutations and mechanisms whereby the major genes affecting ovulation rate. | Qiuyue LIU Zhangyuan PAN Xiangyu WANG Wenping HU Ran DI Yaxing YAO Mingxing CHU | 2014 | Frontiers of Agricultural Science and Engineering2014,1,4: | 3 |
| 17 | Engineering the Interfacial Materials of Organic Field-Effect Transistors for Efficient Charge Transport显示文摘CONSPECTUS:The development of organic field-effect transistors(OFETs)has witnessed impressive advances in organic electronics,which has broad application prospects in artificial intelligence,information technology,energy storage,and medical treatments.How to reveal the interface behavior of charge carriers and how to obtain efficient charge transfer of OFETs are very important scientific issues,which are essential for the construction of highperformance OFETs and also for the further understanding of the intrinsic properties of organic semiconductor materials.To this end,the investigation of interfacial materials and related interface engineering is an effective and promising approach,offering potential capabilities of optimizing molecular packing of semiconductors,interface energy alignments,growth morphology,charge injection/output,and contact resistance for efficient charge transport.In this Account,we present our recent progress on engineering the interface materials of OFETs for efficient charge transport.Polymer dielectrics as indispensable components of OFETs have the capability of tuning the charge transport by modulating the interface,such as surface functionalization,chemical structural optimization,and self-assembly of functional groups into nanostructures.It is noted that the chemical-structure engineered polymer dielectrics endowing them with nanostructures on their surfaces represent a promising method for interface engineering.Besides pure polymer dielectrics,surface self-assembled monolayers also well-tune molecular packing of semiconductors for efficient photogenerated carrier transport in optoelectronic devices.In comparison with dielectric modulation,micro-/nanopatterning of source/drain electrodes is a novel and effective approach to optimize device interfaces and improve device performance for efficient charge transfer.Different from the bulk film,the monolayer semiconductor might produce highly efficient charge transport because of its two-dimensional nature with fewer grain boundaries and interface defects.Thanks to the charge density redistribution occurring at semiconductor/dielectric interface,the monolayer semiconductor on a pure polymer dielectric exhibited highly efficient charge transport.Interface engineering has promoted the significant progress of OFETs in the preceding years.We hope the above-mentioned methodologies of engineering the interfacial materials(e.g.,the dielectric,semiconductor and electrode)to achieve efficient charge transport of OFETs in this Account will offer a new strategy for designing high-performance optoelectronic devices. | Deyang Ji Liqiang Li Harald Fuchs Wenping Hu | 2021 | Accounts of Materials Research2021,2,3: | 3 |
| 18 | Enhanced Hole-Injection Property in an OLED with a Self-assembled Monolayer of Hole-Transporting TPD on Thin Au as the Anode显示文摘A thioester-functionalized triphenylamine hole-transporting molecule(TPD-SAc) was synthesized and self-assembled to form a monolayer on an ultra-thin Au film supported on indium-tin oxide glass. The modified surface was characterized by aqueous contact angle, ellipsometer, atomic force microscopy, X-ray photoelectron spectroscopy, and ultraviolet photoelectron spectrometer to substantiate the formation of compact and pinhole-free monolayers. The modified organic light emitting diode device [indium-tin oxide/Au(5 nm)/self-assembled monolayers(SAM)/TPD(50 nm)/Alq_3(40 nm)/TPBI(15 nm)/LiF(1 nm)/Al(100 nm)] showed a luminance of 7303.90 cd/m^2 and a current efficiency of 8.49 cd/A with 1.78 and 2.29-fold increase, respectively, compared to the control device without SAM. The improvements were attributed to the enhanced compatibility of the organic–inorganic interface, matched energy level by introduction of an energy mediating step and superior hole-injection property of SAM molecules. | Zhi Shang Dongzhi Liu Tianyang Wang Xi Yu Baili Li Wei Li Wenping Hu Xueqin Zhou | 2018 | Transactions of Tianjin University2018,24,6: | 2 |
| 19 | Local delivery of arsenic trioxide nanoparticles for hepatocellular carcinoma treatment显示文摘Hepatocellular carcinoma(HCC)is a malignancy with a poor prognosis.Surgery combined with chemotherapy has been recommended as a curative regimen for HCC.Nevertheless,the anticancer mechanisms of chemicals in hepatocellular carcinoma remain unclear.Pyroptosis is a type of programmed necrosis,and its mechanism in hepatocellular carcinoma is poorly understood.The efficacy and mechanism of arsenic trioxide nanoparticles in the treatment of HCC were explored in this research.Arsenic trioxide alone and arsenic trioxide nanoparticles were conveniently administered to mice intratumorally using a needle.Compared with As_(2)O_(3),As_(2)O_(3)nanoparticles(As_(2)O_(3)-NPs)showed better inhibition,promoted greater LDH release,and induced cell morphology indicative of pyroptosis in vitro.Compared with the free drug,As_(2)O_(3)-NPs increased GSDME-N expression and decreased Dnmt3a,Dnmt3b,and Dnmt1 expression in Huh7 cells.In vivo,As_(2)O_(3)-NPs induced a significant decrease in the expression of Dnmt3a,Dnmt3b and Dnmt1,but significantly upregulated the expression of GSDME-N(gasdermin E(GSDME)was originally found to be related to deafness;recently,it has been defined as a gasdermin family member associated with pyroptosis).As_(2)O_(3)-NPs inhibited tumor growth more strongly than As_(2)O_(3)or control,a finding likely attributed to the downregulation of PCNA and DNMT-related proteins and the upregulation of GSDME-N. | Jian Hu Yi Dong Li Ding Yang Dong Zhihua Wu Wenping Wang Ming Shen Yourong Duan | 2019 | Signal Transduction and Targeted Therapy2019,4,1: | 2 |
| 20 | Analysis of temperature field for a surface-mounted and interior permanent magnet synchronous motor adopting magnetic-thermal coupling method显示文摘Aiming at obtaining high power density of surface-mounted and interior permanent magnet synchronous motor(SIPMSM),it is important to accurately calculate the temperature field distribution of SIPMSM,and a magnetic-thermal coupling method is proposed.The magnetic-thermal coupling mechanism is analyzed.The thermal network model and finite element model are built by this method,respectively.The effects of power frequency on iron losses and temperature fields are analyzed by the magnetic-thermal coupling finite element model under the condition of rated load,and the relationship between the load and temperature field is researched under the condition of the synchronous speed.In addition,the equivalent thermal network model is used to verify the magnetic-thermal coupling method.Then the temperatures of various nodes are obtained.The results show that there are advantages in both computational efficiency and accuracy for the proposed coupling method,which can be applied to other permanent magnet motors with complex structures. | Jikai Si Suzhen Zhao Haichao Feng Yihua Hu Wenping Cao | 2018 | CES Transactions on Electrical Machines and Systems2018,2,1: | 2 |
