1Review of bio-optical imaging systems with a high space-bandwidth product显示文摘Optical imaging has served as a primary method to collect information about biosystems across scales—from functionalities of tissues to morphological structures of cells and even at biomolecular levels.However,to adequately characterize a complex biosystem,an imaging system with a number of resolvable points,referred to as a space-bandwidth product(SBP),in excess of one billion is typically needed.Since a gigapixel-scale far exceeds the capacity of current optical imagers,compromises must be made to obtain either a low spatial resolution or a narrow field-of-view(FOV).The problem originates from constituent refractive optics—the larger the aperture,the more challenging the correction of lens aberrations.Therefore,it is impractical for a conventional optical imaging system to achieve an SBP over hundreds of millions.To address this unmet need,a variety of high-SBP imagers have emerged over the past decade,enabling an unprecedented resolution and FOV beyond the limit of conventional optics.We provide a comprehensive survey of high-SBP imaging techniques,exploring their underlying principles and applications in bioimaging.Jongchan Park David J.Brady Guoan Zheng Lei Tian Liang Gao 2021Advanced Photonics2021,3,4:19

3Infrared upconversion imaging in nonlinear metasurfaces显示文摘Infrared imaging is a crucial technique in a multitude of applications,including night vision,autonomous vehicle navigation,optical tomography,and food quality control.Conventional infrared imaging technologies,however,require the use of materials such as narrow bandgap semiconductors,which are sensitive to thermal noise and often require cryogenic cooling.We demonstrate a compact all-optical alternative to perform infrared imaging in a metasurface composed of GaAs semiconductor nanoantennas,using a nonlinear wave-mixing process.We experimentally show the upconversion of short-wave infrared wavelengths via the coherent parametric process of sum-frequency generation.In this process,an infrared image of a target is mixed inside the metasurface with a strong pump beam,translating the image from the infrared to the visible in a nanoscale ultrathin imaging device.Our results open up new opportunities for the development of compact infrared imaging devices with applications in infrared vision and life sciences.Rocio Camacho-Morales Davide Rocco Lei Xu Valerio Flavio Gili Nikolay Dimitrov Lyubomir Stoyanov Zhonghua Ma Andrei Komar Mykhaylo Lysevych Fouad Karouta Alexander Dreischuh Hark Hoe Tan Giuseppe Leo Costantino De Angelis Chennupati Jagadish Andrey E.Miroshnichenko Mohsen Rahmani Dragomir N.Neshev 2021Advanced Photonics2021,3,3:11
4Spring migration duration exceeds that of autumn migration in Far East Asian Greater White-fronted Geese (Anser albifrons)显示文摘Background:Migration theory suggests,and some empirical studies show, that in order to compete for the best breeding sites and increase reproductive success,long-distance avian migrants tend to adopt a time minimization strategy during spring migration, resulting in shorter duration spring migration compared to that in autumn.Methods:Using GPS/GSM transmitters,we tracked the full migrations of 11 Greater White-fronted Geese (Anser albifrons) between southeast China and the Russian Arctic,to reveal the migration timing and routes of the East Asian population, and compare the difference in duration between spring and autumn migration of this population.Results:We found that migration in spring (79 ± 12 days) took more than twice as long to cover the same distance as in autumn (35 ±7 days).This difference in migration duration was mainly determined by significantly more time spent in spring (59±16 days) than in autumn (23± 6days) at significantly more stopover sites. Conclusions:We suggest that these geese, thought to be partial capital breeders, spent almost three quarters of total migration time at spring stopover sites to acquire energy stores for ultimate investment in reproduction, although we cannot reject the hypothesis that timing of the spring thaw also contributed to stopover duration.In autumn,they acquired necessary energy stores on the breeding grounds sufficient to reach Northeast China staging areas almost without stop, which reduced stopover times in autumn and resulted in the faster autumn migration than spring.Xueqin Deng Qingshan Zhao Lei Fang Zhenggang Xu Xin Wang Haoren He Lei Cao Anthony David Fox 2019Avian Research2019,10,3:9

6Non‑noble Metal Electrocatalysts for the Hydrogen Evolution Reaction in Water Electrolysis显示文摘Water electrolysis is a sustainable approach for hydrogen production by using electricity from clean energy sources.However,both the hydrogen evolution reaction(HER)and the oxygen evolution reaction(OER)associated with water electrolysis are kinetically sluggish,leading to low efficiency in corresponding electrolysis devices.In addition,current electrocatalysts that can catalyze both HER and OER to practical rates require noble metals such as platinum that are low in abundance and high in price,severely limiting commercialization.As a result,the development of high-performance and cost-effective non-noble metal electrocatalysts to replace noble ones has intensified.Based on this,this review will comprehensively present recent research in the design,synthesis,characterization and performance validation/optimization of non-noble metal HER electrocatalysts and analyze corresponding catalytic mechanisms.Moreover,several important types of non-noble metal electrocatalysts including zero-dimensional,one-dimensional,two-dimensional and three-dimensional materials are presented with an emphasis on morphology/structure,synergetic interaction between metal and support,catalytic property and HER activity/stability.Furthermore,existing technical challenges are summarized and corresponding research directions are proposed toward practical application.Huimin Wu Chuanqi Feng Lei Zhang Jiujun Zhang David P.Wilkinson 2021Electrochemical Energy Reviews2021,4,3:7
7Recent advances in connected and automated vehicles显示文摘Connected and automated vehicle(CAV) is a transformative technology that has great potential to change our daily life. Therefore, CAV related research has been advanced significantly in recent years. This paper does a comprehensive review on five selected subjects that lie in the heart of CAV research:(i) inter-CAV communications;(ii) security of CAVs;(iii) intersection control for CAVs;(iv) collision-free navigation of CAVs; and(v)pedestrian detection and protection. It is believed that these topics are essential to ensure the success of CAVs and need to be better understood. For inter-CAV communications, this paper focuses on both Dedicated Short Range Communications(DSRC) and the future 5 G cellular technologies; for security of CAVs, this paper discusses both passive and active attacks and the existing solutions; for intersection control, this paper summarizes the pros and cons of both centralized and decentralized approaches; for collision avoidance, this paper concentrates on four subareas: maneuverability, vehicle networking, control confliction, and motorcycles; for pedestrian detection, this paper covers sensor, radar, and computer vision based approaches. Under each topic, this paper not only shows the stateof-the-art, but also unveils potential future research directions. By establishing connections among these subjects, this paper shows how they interact with each other and how they can be integrated into a seamless user experience. It is believed that the literature covered and conclusions drawn in this paper are very helpful to CAV researchers, application engineers, and policy makers.David Elliott Walter Keen Lei Miao 2019Journal of Traffic and Transportation Engineering(English Edition)2019,6,2:7

9Strain engineering of 2D semiconductors and graphene:from strain fields to band-structure tuning and photonic applications显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDCs)and graphene compose a new family of crystalline materials with atomic thicknesses and exotic mechanical,electronic,and optical properties.Due to their inherent exceptional mechanical flexibility and strength,these 2D materials provide an ideal platform for strain engineering,enabling versatile modulation and significant enhancement of their optical properties.For instance,recent theoretical and experimental investigations have demonstrated flexible control over their electronic states via application of external strains,such as uniaxial strain and biaxial strain.Meanwhile,many nondestructive optical measurement methods,typically including absorption,reflectance,photoluminescence,and Raman spectroscopies,can be readily exploited to quantitatively determine strain-engineered optical properties.This review begins with an introduction to the macroscopic theory of crystal elasticity and microscopic effective low-energy Hamiltonians coupled with strain fields,and then summarizes recent advances in strain-induced optical responses of 2D TMDCs and graphene,followed by the strain engineering techniques.It concludes with exciting applications associated with strained 2D materials,discussions on existing open questions,and an outlook on this intriguing emerging field.Zhiwei Peng Xiaolin Chen Yulong Fan David J.Srolovitz Dangyuan Lei 2020Light(Science & Applications)2020,9,1:6

12Chassis Coordinated Control for Full X-by-Wire Vehicles-A Review显示文摘An X-by-wire chassis can improve the kinematic characteristics of human-vehicle closed-loop system and thus active safety especially under emergency scenarios via enabling chassis coordinated control.This paper aims to provide a complete and systematic survey on chassis coordinated control methods for full X-by-wire vehicles,with the primary goal of summarizing recent reserch advancements and stimulating innovative thoughts.Driving condition identification including driver’s operation intention,critical vehicle states and road adhesion condition and integrated control of X-by-wire chassis subsystems constitute the main framework of a chassis coordinated control scheme.Under steering and braking maneuvers,different driving condition identification methods are described in this paper.These are the trigger conditions and the basis for the implementation of chassis coordinated control.For the vehicles equipped with steering-by-wire,braking-by-wire and/or wire-controlled-suspension systems,state-of-the-art chassis coordinated control methods are reviewed including the coordination of any two or three chassis subsystems.Finally,the development trends are discussed.Lei Zhang Zhiqiang Zhang Zhenpo Wang Junjun Deng David G.Dorrell 2021Chinese Journal of Mechanical Engineering2021,34,2:6
13Artemisinin Biosynthesis in Non-glandular Trichome Cells of Artemisia annua显示文摘Artemisinin-based combination therapy(ACT)forms the first line of malaria treatment.However,the yield fluctuation of artemisinin has remained an unsolved problem in meeting the global demand for ACT.This problem is mainly caused by the glandular trichome(GT)-specific biosynthesis of artemisinin in all currently used Artemisia annua cultivars.Here,we report that non-GT cells of self-pollinated inbred A.annua plants can express the artemisinin biosynthetic pathway.Gene expression analysis demonstrated the transcription of six known pathway genes in GT-free leaves and calli of inbred A.annua plants.LC-qTOF-MS/MS analysis showed that these two types of GT-free materials produce artemisinin,artemisinic acid,and arteannuin B.Detailed IR-MALDESI image profiling revealed that these three metabolites and dihydroartemisinin are localized in non-GT cells of leaves of inbred A.annua plants.Moreover,we employed all the above approaches to examine artemisinin biosynthesis in the reported XL annua glandless(gl)mutant.The resulting data demonstrated that leaves of regenerated gl plantlets biosynthesize artemisinin.Codectively,these findings not only add new knowledge leading to a revision of the current dogma of artemisinin biosynthesis inannua but also may expedite innovation of novel metabolic engineering approaches for high and stable production of artemisinin in the future.Rika Judd M.Caleb Bagley Mingzhuo Li Yue Zhu Caiyan Lei Seyit Yuzuak Mans Ekelof Gaobin Pu Xiting Zhao David C.Muddiman De-Yu Xie 2019Molecular Plant2019,12,5:5
14Assessing site-safeguard effectiveness and habitat preferences of Bar-headed Geese (Anser indicus) at their stopover sites within the Qinghai-Tibet Plateau using GPS/ GSM telemetry显示文摘Background:The Bar-headed Goose(Anser indicus)breeds across the high plains and plateau of Central Asia and winters in the Qinghai-Tibet Plateau(QTP),the Yunnan-Guizhou Plateau and the Indian sub-continent.Of the two recognized discrete flyways of the Bar-headed Goose,the Eastern Tibetan Flyway(ETF)is the larger,comprising at least six migration routes.However,we remain ignorant about their migratory connectivity,habitat use and effectiveness of site-safeguard mechanisms set in place for the species.Methods:We tracked 30 ETF Bar-headed Geese from Chinese and Mongolian breeding areas to their wintering grounds using GPS/GSM transmitters,to determine their migration routes and stopover staging patterns within the QTP,overlaying these upon GIS layers of protected area status and habitat type,to model their habitat selection.Results:In total,14 tagged Bar-headed Geese provided information on their entire autumn migration and 4 geese on their entire spring migration.Qinghai Lake marked birds overwintered in the QTP(n=2),geese tagged in Mongolia wintered either in the QTP(n=3)or in India/Bangladesh(n=9),representing three of the migration routes within the ETF.In total,tagged birds staged at 79 different stopover sites within QTP in autumn and 23 in spring,of which 65%(autumn)and 59%(spring)of all fixes fell within the boundaries of either National Nature Reserves(NNRs)or Important Birds Areas(IBAs)in the QTP.Bar-headed Geese predominantly occurred on four land-cover types:grassland(mostly by day),water bodies(at night),wetlands and bare substrates(salt flats,dry lake/river substrates and plough)with little change in proportion.Generalized linear mixed models comparing presence with pseudo-absence data suggested geese strongly selected for wetlands as staging habitat,avoiding bare substrates in spring.Conclusions:Based on our limited observations of these tagged geese,this study is the first to show that the current designated National Nature Reserves in place in the staging areas within the QTP appear adequate to protect this increasing population.In addition,Hala Lake in Qinghai Province and adjacent areas used as initial QTP staging during autumn migration(currently outside of designated as NNRs/IBAs)are recommended for protection,based on their use by tagged birds from this study.Habitat modelling confirmed the importance of natural wetlands as feeding areas and safe areas of open water as roosting places.Junjian Zhang Yanbo Xie Laixing Li Nyambayar Batbayar Xueqin Deng Iderbat Damba Fanjuan Meng Lei Cao Anthony David Fox 2020Avian Research2020,11,4:5
15Gas–solid interface charge characterisation techniques for HVDC GIS/GIL insulators显示文摘Surface charge accumulation on the spacers is one of the key issues restraining the development of HVDC GIS/GIL.The precise measurement of surface charge properties provides the basis for further study of the surface charge transport mechanism as well as the charge-induced flashover mechanism under DC voltage.In this study,the authors discuss their perspective on the current status,development needs and potential developing orientation of surface charge characterisation techniques.Different surface potential measurement methods and charge inversion algorithms are reviewed regarding the previous studies and future research needs.Drawbacks and outlooks of surface charge measurement techniques are also discussed with the background of laboratory experiment results and on-site measurements.It is hopefully that this study can serve as a useful guide reference for researchers within the same research field.More importantly,it is authors’hope that this study can inspire some novel ideas for readers into developing of more accurate and scientific interface charge characterisation techniques.Lei Zhang Chuanjie Lin Chuanyang Li Simone Vincenzo Suraci Geng Chen Uwe Riechert Tohid Shahsavarian Masayuki Hikita Youping Tu Zhousheng Zhang Davide Fabiani Jinliang He 2020High Voltage2020,5,2:4
16Size matters: wintering ducks stay longer and use fewer habitats on largest Chinese lakes显示文摘Background:Evidence suggests that wintering waterbirds have become conspicuously more concentrated at two largest lakes of the Yangtze River Floodplain,East Dong Ting Lake(Hunan Province,29°20′N,113°E)and Poyang Lake(Jiangxi Province,29°N,116°20′E),relative to other lakes,despite the establishment of reserves elsewhere.While this relationship is likely due to greater extent of undisturbed habitats in larger lakes,we understand little of the drivers affecting individual behaviours behind this tendency.Methods:We tracked wintering movements of three duck species(Eurasian Wigeon Mareca penelope,Falcated Duck M.falcata and Northern Pintail Anas acuta)using GPS transmitters,examining differences between the two largest lakes and other smaller lakes in ducks’habitat use,duration of stay at each lake and the daily distances moved by the tagged birds while at these sites.Results:The Eurasian Wigeon and Falcated Duck stayed five times longer and almost exclusively used natural habitat types at the two large lakes(91‒95%of positions)compared to length of stay time at smaller lakes,where they spent 28‒33 days on average(excluding the capture site)and exploited many more different habitats(including c.50%outside lakes).Conclusions:Our study is the first to show that shorter length of stay and more varied habitat use by ducks at small lakes may contribute to explaining the apparent regional concentration of numbers present of these and other species at the largest lakes in recent years.This compares with their declining abundance at smaller lakes,where habitat loss and degradation has been more manifest than on the larger lakes.Fanjuan Meng Hongbin Li Xin Wang Lei Fang Xianghuang Li Lei Cao Anthony David Fox 2019Avian Research2019,10,4:4
17Cellular and humoral immune interactions between Drosophila and its parasitoids显示文摘The immune interactions occurring between parasitoids and their host insects,especially in Drosophila-wasp models,have long been the research focus of insect immunology and parasitology.Parasitoid infestation in Drosophila is counteracted by its multiple natural immune defense systems,which include cellular and humoral immunity,Occurring in the hemocoel,cellular immune responses involve the proliferation,differentiation,migration and spreading of host hemocytes and parasitoid encapsulation by them.Contrastingly,humoral immune responses rely more heavily on melanization and on the Toll,Imd and Jak/Stat immune pathways associated w ith antimicrobial peptides along with stress factors.On the wasps'side,successful development is achieved by introducing various virulence factors to counteract immune responses of Drosophila.Some or all of these factors manipulate the host's immunity for successful parasitism.Here we review current knowledge of the cellular and humoral immune interactions between Drosophila and its parasitoids,focusing on the defense mechanisms used by Drosophila and the strategies evolved by parasitic wasps to outwit it.Lei Yang Li-Ming Qiu Qi Fang David W.Stanley Gong-Yin Ye 2021Insect Science2021,28,5:3
18New insights into the heat responses of grape leaves via combined phosphoproteomic and acetylproteomic analyses显示文摘Heat stress is a serious and widespread threat to the quality and yield of many crop species,including grape(Vitis vinifera L.),which is cultivated worldwide.Here,we conducted phosphoproteomic and acetylproteomic analyses of leaves of grape plants cultivated under four distinct temperature regimes.The phosphorylation or acetylation of a total of 1011 phosphoproteins with 1828 phosphosites and 96 acetyl proteins with 148 acetyl sites changed when plants were grown at 35℃,40℃,and 45℃in comparison with the proteome profiles of plants grown at 25℃.The greatest number of changes was observed at the relatively high temperatures.Functional classification and enrichment analysis indicated that phosphorylation,rather than acetylation,of serine/arginine-rich splicing factors was involved in the response to high temperatures.This finding is congruent with previous observations by which alternative splicing events occurred more frequently in grapevine under high temperature.Changes in acetylation patterns were more common than changes in phosphorylation patterns in photosynthesis-related proteins at high temperatures,while heat-shock proteins were associated more with modifications involving phosphorylation than with those involving acetylation.Nineteen proteins were identified with changes associated with both phosphorylation and acetylation,which is consistent with crosstalk between these posttranslational modification types.Guo-Tian Liu Jian-Fu Jiang Xin-Na Liu Jin-Zhu Jiang Lei Sun Wei Duan Rui-Min Li Yi Wang David Lecourieux Chong-Huai Liu Shao-Hua Li Li-Jun Wang 2019Horticulture Research2019,6,1:3
19Multilocus Phylogeny of Lycodon and the Taxonomic Revision of Oligodon multizonatum显示文摘Classification of the Asian snake genera Lycodon and Oligodon has proven challenging. We conducted a molecular phylogenetic analysis to estimate the phylogenetic relationships in the genus of Lycodon and clarify the taxonomic status of Oligodon multizonatum using mitochondrial(cyt b, ND4) and nuclear(c-mos) genes. Phylogenetic trees estimated using Maximum Likelihood and Bayesian Inference indicated that O. multizonatum is actually a species of Lycodon. Comparing morphological data from O. multizonatum and its closest relatives also supported this conclusion. Our results imply that a thorough review of the evolutionary relationships in the genus of Lycodon is strong suggested.Juan LEI Xiaoyu SUN Ke JIANG Gernot VOGEL David T.BOOTH Li DING 2014Asian Herpetological Research2014,5,1:3
20Migration routes,population status and important sites used by the globally threatened Black-faced Spoonbill(Platalea minor):a synthesis of surveys and tracking studies显示文摘Background:The Black-faced Spoonbill(Platalea minor)is a globally threatened species,nesting mainly in western Korea with smaller numbers breeding in Liaoning Province,China,and Far East Russia.Recent winter field surveys to estimate the species'population size were almost totally conducted in coastal areas,but tracking studies showed that some individuals now winter inland.To ensure its long-term survival,we need a more comprehensive assessment of the current distribution and abundance of the species.Methods:We combined the most recent count data and satellite tracking information to update existing informa-tion about the population abundance and distribution of the Black-faced Spoonbill at all stages of its annual life cycle,and how these have changed during 2004-2020.Results:Black-faced Spoonbills mainly breed on the west coast of the Korean peninsula,while immature birds show a wider summer distribution throughout Yellow Sea coastal areas,when a few remain on wintering sites in the south.Combined tracking results and mid-winter counts confirmed known wintering sites on the east and south coasts of China,but showed that the species also winters on wetlands in the Yangtze River floodplain and in Southeast Asia.During 2004-2020,counts of wintering birds in coastal habitats increased from 1198 to 4864,with numbers wintering on the island of Taiwan contributing most to the overall increase.Latest counts found 5222 in 2021.We also identify key wintering and stopover sites as well as their current conservation status.Conclusions:This study revised the known summering and wintering ranges of the Black-faced Spoonbill and assessed the conservation status of key sites based on a combination of field survey and satellite tracking data.We recommend prioritisation of further field research to identify and survey inland wintering areas in the Yangtze River floodplain and summering areas of immature birds.More tracking of adult individuals and birds during spring migration is necessary to fill these information gaps.We also suggest establishing a Black-faced Spoonbill monitoring platform to store,share and show real-time distribution range and population abundance data.Yiwen Chen Yat-tung Yu Fanjuan Meng Xueqin Deng Lei Cao Anthony David Fox 2021Avian Research2021,12,4:3
