| 1 | Single-cell analysis reveals bronchoalveolar epithelial dysfunction in COVID-19 patients显示文摘Dear Editor,In 2019,a zoonotic coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was identified as the causative agent of Coronavirus Disease 2019(COVID-19).As of 8 June 2020,the World Health Organization(WHO)has reported 6,912,751 globally confirmed cases with 400,469 deaths.Although generally causes mild disease,SARS-CoV-2 infection can result in serious outcomes,including acute lung injury(ALI)and acute respiratory distress syndrome(ARDS),the leading cause of mortality in patients with comorbidities.Recent autopsy studies of COVID-19 patients revealed mononuclear infiltration and excessive production of mucus in the infected lung,especially in the damaged small airways and alveoli(Bian and Team,2020;Liu et al.,2020). | Jiangping He Shuijiang Cai Huijian Feng Baomei Cai Lihui Lin Yuanbang Mai Yinqiang Fan Airu Zhu Huang Huang Junjie Shi Dingxin Li' Yuanjie Wei Yueping Li Yingying Zhao’ Yuejun Pan He Liu Xiaoneng Mo Xi He Shangtao Cao FengYu Hu Jincun Zhao Jie Wang Nanshan Zhong Xinwen Chen Xilong Deng Jiekai Chen | 2020 | Protein & Cell2020，11，9： | 7 |
| 2 | Measuring high orbital angular momentum of vortex beams with an improved multipoint interferometer显示文摘A multipoint interferometer(MI),uniformly distributed point-like pinholes in a circle,was proposed to measure the orbital angular momentum(OAM)of vortex beams[Phys.Rev.Lett.101,100801(2008)],which can be used for measuring OAM of light from astronomical sources.This is a simple and robust method;however,it is noted that this method is only available for low topological charge because the diffracted intensity patterns for vortex beams with higher OAM will repeat periodically.Here,we propose an improved multipoint interferometer(IMI)for measuring the OAM of an optical vortex with high topological charge.The structure of our IMI is almost the same as the MI,but the size of each pinhole is larger than a point in the MI.Such a small change enables each pinhole to get more phase information from the incident beams;accordingly,the IMI can distinguish any vortex beams with different OAM.We demonstrate its viability both theoretically and experimentally. | QI ZHAO MIAO DONG YIHUA BAI YUANJIE YANG | 2020 | Photonics Research2020，8，5： | 7 |

| 4 | Microstructure and properties of Ag/SnO2 functional material manufactured by selective laser melting显示文摘Ag/SnO2,as a promising and environment-friendly electrical contact material,is widely applied in low-voltage apparatus.But the properties of Ag/SnO2 composites is difficult to improve due to the poor distribution phases and difficult component design.In this work,the Ag/SnO2 composites are prepared by selective laser melting.To get better performance,Ag/SnO2 composites with different energy density were studied.The microstructure was observed by field emission scanning electron microscope.In addition,reinforced SnO2 phase was characterized by X-ray diffraction and transmission electron microscope.The results indicated that the microstructure,relative density and hardness of are influenced by energy density,while Ag/SnO2 composites with homogeneous microstructure,high relative density,higher hardness and lower electrical resistivity can be obtained by proper energy density(E?68 J/mm^3). | Yuanjie Zhang Bo Song Xiao Zhao Yusheng Shi | 2019 | Nano Materials Science2019，1，3： | 5 |
| 5 | Studies on biomechanics of skeletal muscle based on the working mechanism of myosin motors:An overview显示文摘Skeletal muscle is the source of human body motion.Many scholars have been studying in this field to reveal its contraction mechanism,and relevant achievements have been awarded the Nobel Prize.This paper reviewed the current researches on biomechanics of skeletal muscle,and concluded two strategies(top-down and bottom-up methods) for the biomechanical research of skeletal muscle.Moreover,this paper generalized two major aspects of muscle research:(1) the multi-force coupling mechanism and the collective operation mechanism of molecular motors;(2) the bioelectrochemical driving and control principium of muscle contraction.We discussed the solution for experimental verification and induced a novel idea to study the biomechanics of skeletal muscle based on the microscopic working mechanism of molecular motor,which is the origin of muscle contraction.Finally we analyzed the disadvantages in existent researches and explored future directions that need further studies. | YIN YueHong GUO Zhao CHEN Xing FAN YuanJie | 2012 | Chinese Science Bulletin2012，57，35： | 3 |
| 6 | Preprocessing method of night vision image application in apple harvesting robot显示文摘Due to the low working efficiency of apple harvesting robots,there is still a long way to go for commercialization.The machine performance and extended operating time are the two research aspects for improving efficiencies of harvesting robots,this study focused on the extended operating time and proposed a round-the-clock operation mode.Due to the influences of light,temperature,humidity,etc.,the working environment at night is relatively complex,and thus restricts the operating efficiency of the apple harvesting robot.Three different artificial light sources(incandescent lamp,fluorescent lamp,and LED lights)were selected for auxiliary light according to certain rules so that the apple night vision images could be captured.In addition,by color analysis,night and natural light images were compared to find out the color characteristics of the night vision images,and intuitive visual and difference image methods were used to analyze the noise characteristics.The results showed that the incandescent lamp is the best artificial auxiliary light for apple harvesting robots working at night,and the type of noise contained in apple night vision images is Gaussian noise mixed with some salt and pepper noise.The preprocessing method can provide a theoretical and technical reference for subsequent image processing. | Weikuan Jia Yuanjie Zheng De’an Zhao Xiang Yin Xiaoyang Liu Ruicheng Du | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 2 |

| 8 | Partially coherent vortex beams:Fundamentals and applications显示文摘It has been over 30 years since the concept of optical vortices was first proposed by Coullet et al.in 1989,and the field of structured beams has grown extremely.In the last two decades,partially coherent vortex beams(PCVBs)have received increasing interest in the fields of optical manipulation,optical communication,optical imaging,etc.,and great progress has been made in the area of the coherence singularities,generation methods,topological charge measurements,and promising applications of PCVBs.In this review,we firstly outline the basic concepts of PCVBs.We explicate the relationship between the coherence vortices and optical vortices,and the evolution behavior of optical vortices to coherence vortices is summarized in detail.We discuss a special form of coherence singularity,ring dislocation,mathematically and physically.The ring dislocation in the correlation functions under low coherence is dependent on the mode indices,which provide a feasible approach to measure mode indices of PCVBs.Subsequently,we summarize the various methods for measuring the topological charge of PCVBs,highlight the measurement method based on the cross-correlation function,and a physical explanation on the relation between ring dislocation and topological charge is given.After that,we review the recent advances on experimental generation of several kinds of PCVBs.Lastly,we give an overview on the potential applications of PCVBs. | Miao Dong ChengLiang Zhao YangJian Cai YuanJie Yang | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，2： | 1 |
| 9 | Models for economic evaluation of multi-purpose apple harvest platform and software development显示文摘An increasing number of U.S.apple growers are now interested in using harvest platforms to increase harvest productivity,expand labor pool,and alleviate tough working conditions.To maximize benefits,functions of thinning,pruning&training,and infield sorting have been or are to be incorporated into harvest platforms.Though growers are most concerned with economic benefits,few cost-benefit studies had been conducted on different platforms.In the meantime,economic analysis procedure is complex and each analysis is for one specific machine(not for general purposes).No software has been developed as a general and ready-to-use tool for growers and researchers for the platform economic analysis.In this study,platforms,both available on the marketplace and developed in lab as pilot trials,were reviewed.Costs and benefits models were then established,based on which multi-purpose apple harvest platform economic evaluation software(iMPAHP)was developed(capable of evaluating a wide variety of apple harvest platforms).A case study(machine cost of$100000,accommodating 6 workers,processing apple incidence of 10%with 90%sort-out rate,and harvest,thinning,and pruning&training productivity increase by 40%,50%,and 60%,respectively)based on iMPAHP demonstrated that infield sorting,harvest,thinning,and pruning and training accounted for 48.4%,23.9%,14.3%,and 13.4%of the total benefits,respectively.In the case that the platform was in all-four-purpose-application,the net present value(NPV)analysis of a 10-year investment showed a positive return of$60547.However,without infield sorting function,the NPV resulted in a negative value,indicating a loss for the machine investment.Though incorporating the modular infield sorting system certainly increased the overall machine investment by$30000,the benefits outweighed the costs. | Zhao Zhang Zhaohua Zhang Xinmiao Wang Hu Liu Yuanjie Wang Weijie Wang | 2019 | International Journal of Agricultural and Biological Engineering2019，12，1： | 1 |
| 10 | Adsorption behaviors of gas molecules on the surface of ZnO nanocrystals under UV irradiation显示文摘A UV-activated room temperature chemiresistive gas sensor based on ZnO nanocrystals film was fabricated. Its gas sensing properties under various conditions were also investigated in detail. The results shed new insight into the adsorption behaviors of gas molecules on the surface of ZnO nanocrystals under UV irradiation. The chemisorbed oxygen species(O^-2(ads)(hv)) induced by UV light govern the adsorption and desorption ways of other gas molecules on the surface of ZnO nanocrystals, which is dependent on the electron affinity of gas molecules. Gas molecules with higher electron affinity than oxygen molecules can be adsorbed on the surface by the competitive adsorption way, extracting electrons from the surface. Gas molecules with lower electron affinity than oxygen molecules are attracted by the adsorbed O^-2(ads)(hv)layer, releasing electrons to the surface. These processes can influence the gas sensing properties of the sensor. Our findings will pave the way for the fundamental understanding and design of UV-activated gas sensor in the future. | ZHANG QiuPing XIE GuangZhong DU HongFei YANG Jing SU YuanJie TAI HuiLing XU Ming ZHAO Kang | 2019 | Science China(Technological Sciences)2019，62，12： | 1 |
| 11 | Disposable amperometric biosensors based on xanthine oxidase immobilized in the Prussian blue modified screen-printed three-electrode system显示文摘The screen-printed three-electrode system was applied to fabricate a new type of disposable amperometric xanthine oxidase biosensor.Carbon-working,carbon-counter and Ag/AgCl reference electrodes were all manually printed on the polyethylene terephthalate substrate forming the screen-printed three-electrode system by the conventional screen-printing process.As a mediator,Prussian blue could not only catalyze the electrochemical reduction of hydrogen peroxide produced from the enzyme reaction,but also keep the favorable potential around 0 V.The optimum operational conditions,including pH,potential and temperature,were investigated.The sensitivities of xanthine and hypoxanthine detections were 13.83 mA/M and 25.56 mA/M,respectively.A linear relationship was obtained in the concentration range between 0.10μM and 4.98μM for xanthine and between 0.50μM and 3.98μM for hypoxanthine.The small Michaelis-menten constant value of the xanthine oxidase biosensor was calculated to be 3.90 μM.The results indicate that the fabricated xanthine oxidase biosensor is effective and sensitive for the detection of xanthine and hypoxanthine. | TENG YuanJie,CHEN Chen,ZHOU ChangXiang,ZHAO HongLi & LAN MinBo Shanghai key Laboratory of Functional Materials Chemistry Research Center of Analysis Test,East China University of Science and Technology,Shanghai 200237,China | 2010 | Science China Chemistry2010，53，12： | 1 |

| 16 | Ergonomic and efficiency analysis of conventional apple harvest process显示文摘Apples are still manually harvested by workers using ladders and buckets.Though it is known that manual apple harvest would probably lead to occupational injuries(e.g.,back,neck,and shoulder strains),there has been little research that focuses on identifying the awkward activities/postures of pickers during the harvest process.After categorizing apple harvest work into 12 activities,this study used the method of Rapid Upper Limb Assessment(RULA)to identify awkward postures/activities that occurred during apple harvest.Awkward activities confirmed include descending a ladder,dumping apples,picking high and low apples on a ladder as well as on the ground,and moving a ladder,with potential reasons for each awkward activity provided.Meanwhile,it was demonstrated that pickers spent approximately 64%of working time under awkward postures that would lead to occupational diseases.In addition,this study analyzed picker harvest efficiency in terms of general and detail manners.The general mode assessed harvest activity in terms of picking and non-picking,with results showing that pickers averagely spent 76%(±7%)of harvest time in picking apples.Further analysis evaluated picking activities in terms of reaching,detaching,and transporting apples,with results showing that pickers spent averagely 30%(±6%)of time in detaching apples,which is the value time during apple harvest.Furthermore,valuable picking time ratio was obtained as the multiplication of picking time ratio and detaching time ratio.With a valuable ratio of 22%(±5%),it theoretically demonstrated the low harvest efficiency of the traditional harvest method.Since a majority of the awkward activities and the low efficiency were because of the ladders/buckets,using a harvest-assist unit may be a potential solution.Additionally,more efforts should be spent on the development of innovative mechanism to replace worker in placing attached apples to the bucket.Once the time for transporting apples is eliminated,the time for reaching apples is also removed,indicating the harvest efficiency would be improved significantly. | Zhao Zhang Yuanjie Wang Zhaohua Zhang Dapeng Li Zhengze Wu Rui Bai Guangfu Meng | 2019 | International Journal of Agricultural and Biological Engineering2019，12，2： | 1 |

| 20 | The impact of carbon emissions trading policy on carbon emission efficiency in Chinese cities:Evidence from a quasi-natural experiment显示文摘Based on a panel dataset spanning from 2003 to 2019 and encompassing 284 prefecture-level cities in China,this study treats the implementation of the carbon emissions trading policy(CETP)as a quasi-natural experiment.In addition,it employs a spatial difference-in-differences(DID)framework to quantify both the direct and spatially mediated impacts of CETP on urban carbon emission efficiency(CEE).The investigation further delves into the underlying channels of influence and variations within this context.The findings demonstrate that CETP effectively enhances CEE within the cities chosen for piloting;however,it concurrently dampens CEE in nonpiloting neighboring cities.These conclusions remain robust across diverse sensitivity tests.The analysis of mechanisms reveals that CETP’s influence on urban CEE primarily operates through the avenues of technological innovation and optimization of energy structure.Moreover,the study of variances discloses that CETP’s direct effect significantly advances CEE in eastern,old industrial base,and central cities.In terms of indirect effects,a pronounced adverse spatial spillover effect is observed in eastern and old industrial base cities,while noteworthy positive spatial spillover effects emerge in central cities.Notably,the spatial extent of CETP’s influence on urban CEE declines after reaching a distance of 900 km.These insights furnish valuable guidance for China in refining its nationwide carbon market and expediting the shift toward a low-carbon economy. | Keliang Wang Yuanjie Qiao Liwei Ling Ziheng Zhao Kun Liu | 2023 | Chinese Journal of Population,Resources and Environment2023，21，3： | 0 |
