| 1 | Microstructure and mechanical property of a high-strength Mg-10Gd-6Y-1.5Zn-0.5Zr alloy prepared by multi-pass equal channel angular pressing显示文摘In this work,a high-strength Mg–10Gd–6Y–1.5Zn–0.5Zr(wt.%)alloy was fabricated by successive multi-pass equal channel angular pressing(ECAP).The microstructure and mechanical property of as-cast and ECAP alloys were systematically researched by X-ray diffractometer,scanning electron microscopy,transmission electron microscopy and compression test.The results show that the microstructure of as-cast alloy consists ofα-Mg grains,Mg24Y5 networks,18R blocks,fine 14H lamellas,and fewY-rich particles.After 8 passes ECAP,dynamic recrystallization ofα-Mg is developed and their average grain size decreases to about 1μm.The network Mg_(24)Y_(5) phase at grain boundaries is broken into small particles with average diameter lower than 0.5μm.Moreover,18R blocks are kinked and delaminated,or broken into small particles and blended with Mg24Y5 particles.14H lamellas grow gradually or are dynamically precipitated within certainα-Mg grains.Compression tests indicate that 8p ECAP alloy exhibits excellent mechanical property with compressive strength of 537 MPa and fracture strain of 17.0%.The significant improvement for both strength and ductility of deformed alloy could be ascribed to DRX grains,refined Mg24Y5 particles,18R kinking and dynamical precipitation of 14H. | Huan Liu He Huang Xiaowei Yang Cheng Li Jingli Yan Jinghua Jiang Aibin Ma | 2017 | Journal of Magnesium and Alloys2017，5，2： | 10 |
| 2 | Metal-Organic Framework Nanocarriers for Drug Delivery in Biomedical Applications显示文摘Investigation of metal–organic frameworks(MOFs)for biomedical applications has attracted much attention in recent years.MOFs are regarded as a promising class of nanocarriers for drug delivery owing to well-defined structure,ultrahigh surface area and porosity,tunable pore size,and easy chemical functionalization.In this review,the unique properties of MOFs and their advantages as nanocarriers for drug delivery in biomedical applications were discussed in the first section.Then,state-ofthe-art strategies to functionalize MOFs with therapeutic agents were summarized,including surface adsorption,pore encapsulation,covalent binding,and functional molecules as building blocks.In the third section,the most recent biological applications of MOFs for intracellular delivery of drugs,proteins,and nucleic acids,especially aptamers,were presented.Finally,challenges and prospects were comprehensively discussed to provide context for future development of MOFs as efficient drug delivery systems. | Yujia Sun Liwei Zheng Yu Yang Xu Qian Ting Fu Xiaowei Li Zunyi Yang He Yan Cheng Cui Weihong Tan | 2020 | Nano-Micro Letters2020，12，8： | 10 |
| 3 | Effect of wet flue gas desulfurization(WFGD) on fine particle(PM_(2.5)) emission from coal-fired boilers显示文摘In this study, the characteristics of fine particles before and after wet flue gas desulfurization(WFGD) in three coal-fired heating boilers in northern China were investigated by using a dilution-based emission sampling experimental system. The influences of the WFGD process on the mass and number concentrations as well as the chemical composition of fine particles were analyzed. The removal efficiency of desulfurization processes on particulate matter mass was 30.06%–56.25% for the three study units. The WFGD had a great influence on the size distributions of particle mass concentration and number concentration. A significant increase in the number and mass concentration of particles in the size range of 0.094–0.946 μm was observed. The watersoluble ion content accounted for a very large proportion of PM_(2.5) mass, and its proportion in PM_(2.5) increased from 28.39%–41.08% to 48.96%–61.21% after the WFGD process for the three units. The desulfurizing process also drastically increased the proportion of cation component(Ca^(2+) for unit A, Mg^(2+) for unit B, and Na+for unit C) and the proportion of SO_4^(2-) in PM_(2.5), and it increased the CE/AE values of PM_(2.5) from 0.82–0.98 to 0.93–1.27 for the three study units. | Sen Yao Shuiyuan Cheng Jianbing Li Hanyu Zhang Jia Jia Xiaowei Sun | 2019 | Journal of Environmental Sciences2019，31，3： | 8 |
| 4 | Dielectric and Electromagnetic Wave Absorbing Properties of Two Types of SiC Fibres with Different Compositions显示文摘The dielectric and electromagnetic properties of two types of SiC fibres with different compositions were investigated. The permittivity and electromagnetic shielding effectiveness (SE) of SiC fibre bundles were measured in 8.2-12.4 GHz by waveguide method. The reflection coefficient (RC) of unidirectional SiC fibre laminates was determined in 8-18 GHz using naval research laboratory (NRL)-arc method. Results showed that the electromagnetic wave (EMW) absorbing properties of SiC fibres were correlated with their composition, microstructure and instinct performance of electrical resistance. SiC fibres with higher content and greater size of nano-scale β-SiC showed higher permittivity, conductivity, SE and lower RC, which resulted in their better EMW absorbing ability, i.e. the lower reflection to EMW. | Fang Ye Litong Zhang Xiaowei Yin Yongsheng Liu Laifei Cheng | 2013 | Journal of Materials Science & Technology2013，29，1： | 7 |
| 5 | Composition optimized trimetallic PtNiRu dendritic nanostructures as I versatile and active electrocatalysts for alcohol oxidation显示文摘Platinum-based nano crystals are the most effective electrocatalysts for accelerati ng the chemical tran sformatio ns on the anode in direct alcohol fuel cells. To facilitate practical applications and overcome the drawbacks of diverse alcohols, it is significant to develop electrocatalysts with high activities and a wide fuel flexibility. Here, we demonstrate a practicable solution method for fabricating composition tun able trimetallic PtNiRu den dritic nano structures (DNSs) which can serve as versatile and active catalysts for electrooxidatio n of a variety of liquid alcohols. A series of trimetallic DNSs with tun able Pt/Ni/Ru atomic ratios were successfully syn thesized by simply adjusti ng the feeding of precursors. Detailed electrochemical test indicates that, among other compositions, the Pt66Ni27Ru7 DNSs present much superior electroactivity in catalyzing electrooxidation of liquid alcohols in acidic mediums. Specifically, the mass activity and specific activity on the Pt66Ni27Ru7 DNSs, for electrooxidation of methanol, ethanol, and ethylene glycol, are 4.57 and 4.34 times, 3.55 and 3.42 times, and 2.37 and 2.28 times that of the commercial Pt black, respectively. X-ray photoelectron spectroscopy and CO stripping studies reveal the adsorption of CO on these PtNiRu DNSs is much weaker than on pure Pt. Meanwhile, the surface Ru sites can provide neighbouring -OH groups to facilitate the oxidati on and removal of the adsorbed in termediates (-CO) on the surface Pt sites, effectively improvi ng the CO tolera nee of the catalysts. The PtNiRu DNSs also show effectively boosted capacity for breaking the C-C bond in C2-alcohols, showing great potential for fuel-flexible fuel cell applications. | Yan Lu Wei Wang Xiaowei Chen Yuhui Zhang Yanchen Han Yong Cheng Xue-Jiao Chen Kai Liu Yuanyuan Wang Qiaobao Zhang Shuifen Xie | 2019 | Nano Research2019，12，3： | 6 |
| 6 | Effects of Heating and Hot Extrusion Process on Microstructure and Properties of Inconel 625 Alloy显示文摘The effects of the heating process and hot extrusion on the microstructure and properties of inconel 625 alloy were studied. The experimental results showed that the properties of Inconel 625 alloy could be improved through the heating process and hot extrusion concomitant with a reduced corrosion rate. The M23C6 carbide, generated in the heating process, was retained and distributed at the grain boundary during the process of hot extrusion, which had an important influence on both elongation and corrosion resistance. The improvement of the comprehensive properties of the material, as measured by a tensile test at room temperature, was correlated with the dissolution of segregation Nb. A typical ductile fracture changed to a cleavage fracture where secondary cracks could be clearly seen. With the increase of the extrusion ratio, the real extrusion temperature was higher, which led to more dissolution of the M23C6 carbide, decreased the number of secondary cracks, enhanced the effect of solid solution strengthening, and reduced the intergranular corrosion rate. Under the condition of a high extrusion ratio and a high extrusion speed, the less extrusion time made it possible to obtain organization with a smaller average grain size. Moreover, in this case, the M23C6 carbide and segregated Nb did not have enough time to diffuse. Thus all samples exhibited medium strengths and corrosion rates after extrusion. | 刘德学 CHENG Xiaowei ZHANG Xiao DING Yutian | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，6： | 5 |
| 7 | Networking retinomorphic sensor with memristive crossbar for brain-inspired visual perception显示文摘Compared to human vision,conventional machine vision composed of an image sensor and processor suffers from high latency and large power consumption due to physically separated image sensing and processing.A neuromorphic vision system with brain-inspired visual perception provides a promising solution to the problem.Here we propose and demonstrate a prototype neuromorphic vision system by networking a retinomorphic sensor with a memristive crossbar.We fabricate the retinomorphic sensor by using WSe_(2)/h-BN/Al_(2)O_(3)van der Waals heterostructures with gate-tunable photoresponses,to closely mimic the human retinal capabilities in simultaneously sensing and processing images.We then network the sensor with a large-scale Pt/Ta/Hf O_(2)/Ta one-transistor-one-resistor(1 T1 R)memristive crossbar,which plays a similar role to the visual cortex in the human brain.The realized neuromorphic vision system allows for fast letter recognition and object tracking,indicating the capabilities of image sensing,processing and recognition in the full analog regime.Our work suggests that such a neuromorphic vision system may open up unprecedented opportunities in future visual perception applications. | Shuang Wang Chen-Yu Wang Pengfei Wang Cong Wang Zhu-An Li Chen Pan Yitong Dai Anyuan Gao Chuan Liu Jian Liu Huafeng Yang Xiaowei Liu Bin Cheng Kunji Chen Zhenlin Wang Kenji Watanabe Takashi Taniguchi Shi-Jun Liang Feng Miao | 2021 | National Science Review2021，8，2： | 5 |
| 8 | Ordered porous metal oxide semiconductors for gas sensing显示文摘Among various gas sensing materials, metal oxide semiconductors have shown great potential as resistive type sensors.

| 10 | Recyclable Fenton-like catalyst based on zeolite Y supported ultrafine,highly-dispersed Fe_2O_3 nanoparticles for removal of organics under mild conditions显示文摘A versatile wet impregnation method was employed to conveniently and controllably deposit Fe_2O_3 nanoparticles on zeolites including commercial Y, mordenite and ZSM-5 with the similar framework Si/Al ratios and crystal sizes, respectively. The ultrafine Fe_2O_3 nanoparticles in size of 5 nm can be highly dispersed on zeolite Y matrix due to its much better wettability than ZSM-5 and mordenite. By using the obtained Fe_2O_3/zeolite composite as the heterogeneous Fenton-like catalysts, the degradation of phenol as a model reaction was systematically investigated, including the zeolite supports, particle size and dispersion of Fe_2O_3, and reaction conditions of H_2O_2 concentration, temperature, and pH value. The catalyst based on zeolite Y with Fe loading of 9% exhibited the best phenol degradation efficiency (> 90%)in neutral pH within 2 h. Its high catalytic activity in Fenton reaction can be attributed to the bifunctional properties of strong surface BrФnsted acidity and high reactivity of octahedral Fe^(3+) in the highlydispersed ultrafine Fe_2O_3 nanoparticles in size of 5 nm, which were the primary active centers to quickly decompose H_2O_2 into hydroxyl radicals. Since phenol degradation can be performed under mild conditions of ambient temperature (283-323 K) and a wide pH range (4.0-7.0), the catalysts can be easily recovered for recyclable use with stable degradation activity, which own the immense potential in deep treatment of organic pollutants in industrial wastewater. | Xuanyu Yang Xiaowei Cheng Ahmed A.Elzatahry Jinyang Chen Abdulaziz Alghamdi Yonghui Deng | 2019 | Chinese Chemical Letters2019，30，2： | 4 |
| 11 | Single-cell transcriptomes of peripheral blood cells indicate and elucidate severity of COVID-19显示文摘The blood and immune system of coronavirus disease 2019(COVID-19)infected patients are dysfunctional,and numerous studies have been conducted to resolve their characteristics and pathogenic mechanisms.Nevertheless,the variations of immune responses along with disease severity have not been comprehensively documented.Here,we profiled the single-cell transcriptomes of 96,313 peripheral blood mononuclear cells(PBMCs)derived from 12 COVID-19 patients(including four moderate,four severe and four critical cases)and three healthy donors.We showed that proliferative CD8 effector T cells with declined immune functions and cytotoxicity accumulated in the critical stage.By contrast,the quantity of natural killer(NK)cells was significantly reduced,while they exhibited enhanced immune activities.Notably,a gradually attenuated responseto COVID-19 along with disease severity was observed in monocytes,in terms of cellular composition,transcriptional discrepancy and transcription factor regulatory network.Furthermore,we identified immune cell-type dependent cytokine signatures distinguishing the severity of COVID-19 patients.In addition,cell interactions between CD8 effector T/NK cells and monocytes mediated by inflammatory cytokines were enhanced in moderate and severe stages,but weakened in critical cases.Collectively,our work uncovers the cellular and molecular players underlying the disordered and heterogeneous immune responses associated with COVID-19 severity,which could provide valuable insights for the treatment of critical COVID-19 patients. | Xiaowei Xie Xuelian Cheng Gaoxiang Wang Biao Zhang Mengyao Liu Liting Chen Hui Cheng Sha Hao Jianfeng Zhou Ping Zhu Tao Cheng | 2021 | Science China(Life Sciences)2021，64，10： | 3 |
| 12 | Proportional Limit Stress and Residual Thermal Stress of 3D SiC/SiC Composite显示文摘Proportional limit stress(PLS) and residual thermal stresses(RTS) of 3D SiC/SiC composite were investigated.PLS was obtained by four different methods from the monotonic stress—strain response curve to get a convincing value.RTS in the SiC matrix was quantified by solving the geometric intersection point of the regression lines of hysteresis loops from the periodical loading—unloading—reloading cycle test curve.Classical ACK model and analytical formulas were used to analytically calculate the PLS and RTS of 3D SiC/SiC composite.Good agreement between the experimental results and the analytical calculation was observed.And relationship between the PLS and the RTS of 3D SiC/SiC was discussed. | Shanhua Liu Litong Zhang Xiaowei Yin Yongsheng Liu Laifei Cheng | 2014 | Journal of Materials Science & Technology2014，30，10： | 3 |
| 13 | New true-triaxial rock strength criteria considering intrinsic material characteristics显示文摘A reasonable strength criterion should reflect the hydrostatic pressure effect, minimum principal stress effect,and intermediate principal stress effect. The former two effects can be described by the meridian curves, and the last one mainly depends on the Lode angle dependence function. Among three conventional strength criteria, i.e.Mohr–Coulomb(MC), Hoek–Brown(HB), and Exponent(EP) criteria, the difference between generalized compression and extension strength of EP criterion experience a firstly increase then decrease process, and tends to be zero when hydrostatic pressure is big enough. This is in accordance with intrinsic rock strength characterization. Moreover, the critical hydrostatic pressure I_c corresponding to the maximum difference of between generalized compression and extension strength can be easily adjusted by minimum principal stress influence parameter K. So, the exponent function is a more reasonable meridian curves, which well reflects the hydrostatic pressure effect and is employed to describe the generalized compression and extension strength.Meanwhile, three Lode angle dependence functions of L_(MN),L_(WW), and L_(YMH), which unconditionally satisfy the convexity and differential requirements, are employed to represent the intermediate principal stress effect. Realizing the actual strength surface should be located between the generalized compression and extension surface, new true-triaxial criteria are proposed by combining the two states of EP criterion by Lode angle dependence function with a same lode angle. The proposed new true-triaxial criteria have the same strength parameters as EP criterion. Finally, 14 groups of triaxial test data are employed to validate the proposed criteria. The results show that the three new true-triaxial exponent criteria,especially the Exponent Willam-Warnke criterion(EPWW)criterion, give much lower misfits, which illustrates that the EP criterion and L_(WW) have more reasonable meridian and deviatoric function form, respectively. The proposed new true-triaxial strength criteria can provide theoretical foundation for stability analysis and optimization of support design of rock engineering. | Qiang Zhang Cheng Li Xiaowei Quan Yanning Wang Liyuan Yu Binsong Jiang | 2018 | Acta Mechanica Sinica2018，34，1： | 3 |
| 14 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |
| 15 | Mesoporous TiO_2/Carbon Beads: One-Pot Preparation and Their Application in Visible-Light-Induced Photodegradation显示文摘Mesoporous Ti O2/Carbon beads have been prepared via a facile impregnation-carbonization approach, in which a porous anion-exchange resin and K2 Ti O(C2O4)2were used as hard carbon and titanium source, respectively.Characterization results reveal that the self-assembled composites have disordered mesostructure, uniform mesopores,large pore volumes, and high surface areas. The mesopore walls are composed of amorphous carbon, well-dispersed and confined anatase or rutile nanoparticles. Some anatase phase of Ti O2 was transformed to rutile phase via an increase of carbonization temperature or repeated impregnation of the resin with Ti O(C2O4)22-species. X-ray photoelectron spectroscopy, carbon, hydrogen, and nitrogen element analysis, and thermal gravity analysis results indicate the doping of carbon into the Ti O2 lattice and strong interaction between carbon and Ti O2 nanoparticles. A synergy effect by carbon and Ti O2 in the composites has been discussed herein on the degradation of methyl orange under visible light. The dye removal process involves adsorption of the dye from water by the mesopores in the composites, followed by photodegradation on the separated dye-loaded catalysts. Mesopores allow full access of the dye molecules to the surface of Ti O2 nanoparticles.Importantly, the bead format of such composite enables their straightforward separation from the reaction mixture in their application as a liquid-phase heterogeneous photodegradation catalyst. | Xiaowei Li Yanqiu Jiang Wenjing Cheng Yudong Li Xianzhu Xu Kaifeng Lin | 2015 | Nano-Micro Letters2015，7，3： | 2 |
| 16 | Recent advance in synthesis and application of heteroatom zeolites显示文摘Incorporation of heteroatoms into the framewo rk of zeolites has become a significant strategy to improve their performance in catalysis and adsorption,because the obtained heteroatom zeolites exhibit quite different properties from the conventional aluminosilicate zeolites in aspects of surface acidity,pore structures,particle size and so on.In this review,the progress on the heteroatom zeolites including their synthesis and application is highlighted.First,the recent advance on the design and synthesis of different heteroatom zeolites is summarized.Special emphasis is placed on the introduction and comparison of three typical methods,including the direct synthesis,post synthesis and improved direct synthesis,for the traditional heteroatom zeolites(such as TS-1,Sn-MFI,Sn-β) and newly-reported heteroatom zeolites(such as W-MFI,Mo-MFI).According to their intrinsic characteristics,the application of heteroatom zeolites in diverse fields,such as production of fine chemicals,air pollution control and biomass conversion is then discussed.Finally,the challenges and perspective on the future development of heteroatom zeolites in low-cost preparation and practical application are proposed. | Tingting Pang Xuanyu Yang Chenyi Yuan Ahmed A.Elzatahry Abdulaziz Alghamdi Xing He Xiaowei Cheng Yonghui Deng | 2021 | Chinese Chemical Letters2021，32，1： | 2 |
| 17 | Dielectric,Electromagnetic Interference Shielding and Absorption Properties of Si_3N_4-PyC Composite Ceramics显示文摘Pyrolytic carbon(PyC) was infiltrated into silicon nitride(Si3N4) ceramics by precursor infiltration and pyrolysis (PIP) of phenolic resin,and Ni nanoparticles were added into the phenolic resin to change the electric conductivity of Si3N4-PyC composite ceramics.Dielectric permittivity,electromagnetic interference(EMI) shielding and absorption properties of Si3N4—PyC composite ceramics were studied as a function of Ni content at 8.2—12.4 GHz(X-band).When Ni nanoparticles were added into phenolic resin,the electric conductivity of the prepared composite ceramics decreased with increasing Ni content,which was attributed to the decrease of graphitization degree of PyC.The decrease in electric conductivity led to the decrease in both permittivity and EMI shielding effectiveness.Since too high permittivity is harmful to the impendence match and results in the strong reflection,the electromagnetic wave absorption property of Si3N4—PyC composite ceramics increases with increasing Ni content.When the content of Ni nanoparticles added into phenolic resin was 2 wt%,the composite ceramics possessed the lowest electric conductivity and displayed the most excellent absorption property with a minimum reflection loss as low as -28.9 dB. | Xuan Hao Xiaowei Yin Litong Zhang Laifei Cheng | 2013 | Journal of Materials Science & Technology2013，29，3： | 2 |
| 18 | Preparation and photocatalytic activity of Fe3O4@SiO2@ZnO:La显示文摘In this study,Fe3 O4@SiO2@ZnO:La microspheres were successfully prepared.The microspheres have the advantages of both ZnO doped with La and the Fe3 O4@SiO2 structure such that the former improves the photocatalytic activity of ZnO and the latter can be reused.The X-ray diffraction(XRD),a field emission scanning electron microscope(SEM),a field emission transmission electron microscope(TEM),X-ray photoelectron spectroscopy(XPS),and a vibrating sample magnetometer(VSM)were used to characterize Fe3 O4@SiO2@ZnO:La microspheres.Methyl orange was used as the model molecule to study the effect of the Zn2+concentration and the doping amount of La on the photocatalytic activity of Fe3 O4@SiO2@ZnO:La microspheres.Results show that in the synthesis of Fe3 O4@SiO2@ZnO:La microspheres,photocatalytic activity of the microspheres is enhanced first and weakened later with the increase of Zn2+concentration.In the La doping process,the photocatalytic activity of Fe3 O4@SiO2@ZnO:La microspheres is enhanced with the increase in the La doping amount.The magnetic photocatalysts not only have high photocatalytic activity,but also can be reused.After being reused five times,the photocatalyst’s degradation rate of methyl orange is still as high as 81%,which shows that magnetic photocatalysts have prospective wider applications in photocatalytic degradation of dye wastewater. | Xiaowei Lv Wenyi Huang Xingcheng Ding Jiangwei He Qiumei Huang Jialin Tan Hao Cheng Jun Feng Lijun Li | 2020 | Journal of Rare Earths2020，38，12： | 2 |

| 20 | Sparse reconstruction for fluorescence molecular tomography via a fast iterative algorithm显示文摘Fluorescence molecular tomography(FMT)is a fast-developing optical imaging modalitythat has great potential in early diagnosis of disease and drugs development.However,recon-struction algorithms have to address a highly ill-posed problem to fulfll 3D reconstruction inFMT.In this contribution,we propose an efficient iterative algorithm to solve the large-scalereconstruction problem,in which the sparsity of fluorescent targets is taken as useful a prioriinformation in designing the reconstruction algorithm.In the implementation,a fast sparseapproximation scheme combined with a stage-wise learning strategy enable the algorithm to dealwith the ill-posed inverse problem at reduced computational costs.We validate the proposed fastiterative method with numerical simulation on a digital mouse model.Experimental results demonstrate that our method is robust for different finite element meshes and different Poissonnoise levels. | Jingjing Yu Jingxing Cheng Yuqing Hou Xiaowei He | 2014 | Journal of Innovative Optical Health Sciences2014，7，3： | 2 |
