| 1 | Fast structured illumination microscopy via deep learning显示文摘This study shows that convolutional neural networks(CNNs)can be used to improve the performance of structured illumination microscopy to enable it to reconstruct a super-resolution image using three instead of nine raw frames,which is the standard number of frames required to this end.Owing to the isotropy of the fluorescence group,the correlation between the high-frequency information in each direction of the spectrum is obtained by training the CNNs.A high-precision super-resolution image can thus be reconstructed using accurate data from three image frames in one direction.This allows for gentler super-resolution imaging at higher speeds and weakens phototoxicity in the imaging process. | CHANG LING CHONGLEI ZHANG MINGQUN WANG FANFEI MENG LUPING DU XIAOCONG YUAN | 2020 | Photonics Research2020，8，8： | 8 |
| 2 | Time effect and prediction of broken rock bulking coefficient on the base of particle discrete element method显示文摘Bulking characteristics of gangue are of great significance for the stability of goafs in mining overburden in the caving zones.In this paper,a particle discrete element method with clusters to represent gangue was adopted to explore the bulking coefficient time effect of the broken rock in the caving zone under three-dimensional triaxial compression condition.The phenomena of stress corrosion,deformation,and failure of rock blocks were simulated in the numerical model.Meanwhile,a new criterion of rock fragments damage was put forward.It was found that the broken rock has obvious viscoelastic properties.A new equation based on the Burgers creep model was proposed to predict the bulking coefficient of broken rock.A deformation characteristic parameter of the prediction equation was analyzed,which can be set as a fixed value in the mid-and long-term prediction of the bulking coefficient.There are quadratic function relationships between the deformation characteristic parameter value and Talbot gradation index,axial pressure and confining pressure. | Fanfei Meng Hai Pu Takashi Sasaoka Hideki Shimada Sifei Liu Tumelo KM Dintwe Ziheng Sha | 2021 | International Journal of Mining Science and Technology2021，31，4： | 1 |
| 3 | Measuring the magnetic topological spin structure of light using an anapole probe显示文摘Topological spin structures of light,including the Skyrmion,Meron,and bi-Meron,are intriguing optical phenomena that arise from spin-orbit coupling.They have promising potential applications in nano-metrology,data storage,super-resolved imaging and chiral detection.Aside from the electric part of optical spin,of equal importance is the magnetic part,particularly the H-type electromagnetic modes for which the spin topological properties of the field are dominated by the magnetic field.However,their observation and measurement remains absent and faces difficult challenges.Here,we design a unique type of anapole probe to measure specifically the photonic spin structures dominated by magnetic fields.The probe is composed of an Ag-core and Si-shell nanosphere,which manifests as a pure magnetic dipole with no electric response.The effectiveness of the method was validated by characterizing the magnetic field distributions of various focused vector beams.It was subsequently employed to measure the magnetic topological spin structures,including individual Skyrmions and Meron/Skyrmion lattices for the first time.The proposed method may be a powerful tool to characterize the magnetic properties of optical spin and valuable in advancing spin photonics. | Fanfei Meng Aiping Yang Kang Du Fengyang Jia Xinrui Lei Ting Mei Luping Du Xiaocong Yuan | 2022 | Light(Science & Applications)2022，11，10： | 1 |
| 4 | Application Effect of Sludge Extract in the Planting of Zinnia elegans显示文摘[Objectives] The research aimed to study the effect of sludge extract on the growth of Zinnia elegans, and evaluate its possibility of application. [Methods] Z. elegans was taken as research object, and the effect of sludge extract on the growth indicators of Z. elegans was studied. [Results] The sludge extract can obviously promote the growth of Z. elegans, and the growth indicators were significantly improved when compared with the control group. The application effect was close to that of foliar fertilizer purchased in the market. In each treatment group, the low concentration of sludge extract did not significantly promote the growth of Z. elegans, while too high concentration could inhibit its growth, and the optimal dilution ratio was 600 times. [Conclusions] Further preparation of amino acid foliar fertilizer from sludge extract and its application in planting garden plants can realize the resource utilization of sludge and has a good development and application prospect. | Yu FU Cheng YANG Lifang CUI Fanfei MENG Aiai YANG Guangneng ZENG | 2022 | Asian Agricultural Research2022，14，9： | 0 |
| 5 | Mapping the distributions of blood-sucking mites and mite-borne agents in China:a modeling study显示文摘Background:Emerging mite-borne pathogens and associated disease burdens in recent decades are raising serious public health concerns,yet their distributions and ecology remain under-investigated.We aim to describe the geographical distributions of blood-sucking mites and mite-borne agents and to assess their ecological niches in China.Methods:We mapped 549 species of blood-sucking mites belonging to 100 genera at the county level and eight mite-associated agents detected from 36 species of blood-sucking mites in China during 1978–2020.Impacts of climatic and environmental factors on the ecology of 21 predominant vector mites and a leading pathogen,Orientia tsutsugamushi,were assessed using boosted regression tree(BRT)models,and model-predicted risks were mapped.We also estimated the model-predicted number,area and population size of afected counties for each of the 21 mite species in China.Results:Laelaps echidninus is the leading mite species that potentially afects 744 million people,followed by La.jettmari(517 million)and Eulaelaps stabularis(452 million).Leptotrombidium scutellare is the mite species harboring the highest variety of mite-borne agents including four Rickettsia species and two viruses,followed by Eu.stabularis(2 agents),L.palpale(2)and La.echidninus(2).The top two agents that parasitize the largest number of mite species are O.tsutsugamushi(28 species)and hantavirus(8).Mammalian richness,annual mean temperature and precipitation of the driest quarter jointly determine the ecology of the mites,forming four clusters of major mite species with distinct geographic distributions.High-risk areas of O.tsutsugamushi are mainly distributed in southern and eastern coastal provinces where 71.5 million people live.Conclusions:Ecological niches of major mite species and mite-borne pathogens are much more extensive than what have been observed,necessitating expansion of current fled surveillance. | Tao Wang Fanfei Meng Tianle Che Jinjin Chen Haiyang Zhang Yang Ji Zhengwei Fan Guoping Zhao Wenhui Zhang Baogui Jiang Qiang Xu Chenlong Lv Taoxing Shi Shiman Ruan Lanzheng Liu Wei Liu Yang Yang Liqun Fang | 2022 | Infectious Diseases of Poverty2022，11，2： | 0 |
| 6 | Optimization Study on Oxidative Desulfurization of Crude Oil under Electric Field显示文摘Oxidative desulfurization (ODS) of Azeri crude oil was studied under the electric field.By means of orthogonal experiments,the optimum conditions for desulfurization of crude oil were identified,while the effect of oxidative desulfurization under the electric field was compared with that of the single oxidative desulfurization method.The test results showed that the desulfurization reaction taking place under the electric field would be better than the traditional method.The desulfurization rate of crude oil could reach up to 77.06% at 115 ℃ at a distilled water amount of 10 m%,a desulfurizer dosage of 200 μg/g,and a demulsifier dosage of 50 μg/g. | Liu Lin Lü Hong Meng Fanfei Wang Ning He Yiyi (Liaoning Province Key Laboratory for Synthesis and Application of Functional Compounds,Bohai University,Jinzhou 121013) | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，3： | 0 |
| 7 | Strength test of 3D printed artificial rock mass with pre-existing fracture显示文摘Discontinuities or structural planes are widely distributed in natural rock masses and significantly influence their geo-mechanical and geometric properties.Herein,a batch of rock samples,each with a single structural plane,is created using a 3D printer equipped with two robotic manipulators.One of the manipulators is connected via a nozzle to a concrete pumping truck,which can extrude brittle rock-like material to form layered intact rock masses;the rock-like material is mainly composed of cement,silica fume,sand and water.The other manipulator features a knife,which can carve discontinuities onto each layer of the printed model.By means of this system,rock masses with discontinuous joints are formed,and the failure strengths of rock masses with different joints are demonstrated via uniaxial compression tests and direct shear tests.The results thereof obtained via digital image correlation technology show that discontinuities lower the strength of the rock mass models significantly.With the increase of the angle between the fracture and horizontal plane,the uniaxial compressive strength first decreases,and then increases.During shear testing,the shear strength of the rock mass models increases with the surface roughness of the preset joint.These test results indicate that the influence of artificial joints on the mechanical properties of the models is consistent with that of natural rock mass joints.Using digital modeling and 3D printing technology,cracks hidden in a rock mass can be reproduced. | Youyu Wang Li Wang Fanfei Meng Kang Chen | 2021 | Underground Space2021，6，5： | 0 |
