4A review of road extraction from remote sensing images显示文摘As a significant role for traffic management,city planning,road monitoring,GPS navigation and map updating,the technology of road extraction from a remote sensing(RS) image has been a hot research topic in recent years.In this paper,after analyzing different road features and road models,the road extraction methods were classified into the classification-based methods,knowledge-based methods,mathematical morphology,active contour model,and dynamic programming.Firstly,the road features,road model,existing difficulties and interference factors for road extraction were analyzed.Secondly,the principle of road extraction,the advantages and disadvantages of various methods and research achievements were briefly highlighted.Then,the comparisons of the different road extraction algorithms were performed,including road features,test samples and shortcomings.Finally,the research results in recent years were summarized emphatically.It is obvious that only using one kind of road features is hard to get an excellent extraction effect.Hence,in order to get good results,the road extraction should combine multiple methods according to the real applications.In the future,how to realize the complete road extraction from a RS image is still an essential but challenging and important research topic.Weixing Wang Nan Yang Yi Zhang Fengping Wang Ting Cao Patrik Eklund 2016Journal of Traffic and Transportation Engineering(English Edition)2016,3,3:9

6Epithelial cysts of the spleen:A minireview显示文摘Primary splenic epithelial cyst is an unusual event in everyday surgical practice with about 800 cases reported until date in the English literature. Splenic cysts may be parasitic or non-parasitic in origin. Nonparasitic cysts are either primary or secondary. Primary cysts are also called true,congenital,epidermoid or epithelial cysts. Primary splenic cysts account for 10% of all benign non-parasitic splenic cysts and are the most frequent type of splenic cysts in children. Usually,splenic cysts are asymptomatic and can be found incidentally during imaging techniques or on laprotomy. The symptoms are related to the size of cysts. When they assume large sizes,they may present with fullness in the left abdomen,local or referred pain,symptoms due to compression of adjacent structures(like nausea,vomiting,flatulence,diarrhoea) or rarely thrombocytopenia,and occasionally complications such as infection,rupture and/or haemorrhage. The preoperative diagnosis of primary splenic cysts can be ascertained by ultrasonography(USG),computed tomography or magnetic resonance imaging,although the wide use of USG today has led to an increase in the incidence of splenic cysts by 1%. However,careful histopathological evaluation along with immunostaining for presence of epithelial lining is mandatory to arrive at the diagnosis. The treatment has changed drastically from total splenectomy in the past to splenic preservation methods recently.Sachin B Ingle Chitra R Hinge (Ingle) Swapna Patrike 2014World Journal of Gastroenterology2014,20,38:6
7Hot deformation of Mg-Y-Zn alloy with a low content of the LPSO phase studied by in-situ synchrotron radiation diffraction显示文摘The compressive deformation behavior of the extruded WZ42(Mg98.5Y1Zn0.5 in at.%)magnesium alloy containing a low amount of long-period stacking ordered(LPSO)phase was studied by in-situ synchrotron radiation diffraction technique.Tests were conducted at temperatures between room temperature and 350℃.Detailed microstructure investigation was provided by scanning electron microscopy,particularly the backscattered electron imaging and electron backscatter diffraction technique.The results show that twinning lost its dominance and kinking of the LPSO phase became more pronounced with increasing deformation temperature.No cracks of the LPSO phase and no debonding r at the interface between the LPSO phase and the Mg matrix were observed at temperatures above 200℃.At 350℃,the LPSO phase lost its strengthening effect and the deformation of the alloy was mainly realized by the dynamic recrystallization of the Mg matrix.Klaudia Horváth Fekete Daria Drozdenko Jan Capek Kristián Máthis Domonkos Tolnai Andreas Stark Gerardo Garcés Patrik Dobron 2020Journal of Magnesium and Alloys2020,8,1:5

10Influence of confining prestress on the transition from interface defeat topenetration in ceramic targets显示文摘Replica scaled impact experiments with unconfined ceramic targets have shown that the transition velocity,i.e.,the impact velocity at which interface defeat ceases and ceramic penetration occurs,decreased as the length scale increased.A possible explanation of how this scale effect is related to the formation of a cone crack in the ceramic has been presented by the authors in an earlier paper.Here,the influence of confinement and prestress on cone cracking and transition velocity is investigated.The hypothesis is that prestress will suppress the formation and growth of the cone crack by lowering the driving stress.A set of impact experiments has been performed in which the transition velocity for four different levels of prestress has been determined.The transition velocities as a function of the level of confining prestress is compared to an analytical model for the influence of prestress on the formation and extension of the cone crack in the ceramic material.Both experiments and model indicate that prestress has a strong influence on the transition from interface defeat to penetration,although the model underestimates the influence of prestress.Patrik LUNDBERG RenéRENSTROM Olof ANDERSSON 2016Defence Technology(防务技术)2016,12,3:4
11Incorporation of bioactive glass nanoparticles in electrospun PCL/chitosan fibers by using benign solvents显示文摘The use of bioactive glass(BG)particles as a filler for the development of composite electrospun fibers has already been widely reported and investigated.The novelty of the present research work is represented by the use of benign solvents(like acetic acid and formic acid)for electrospinning of composite fibers containing BG particles,by using a blend of PCL and chitosan.In this work,different BG particle sizes were investigated,namely nanosized and micron-sized.A preliminary investigation about the possible alteration of BG particles in the electrospinning solvents was performed using SEM analysis.The obtained composite fibers were investigated in terms of morphological,chemical and mechanical properties.An in vitro mineralization assay in simulated body fluid(SBF)was performed to investigate the capability of the composite electrospun fibers to induce the formation of hydroxycarbonate apatite(HCA).Liliana Liverani Jonas Lacina Judith A.Roether Elena Boccardi Manuela S.Killian Patrik Schmuki Dirk W.Schubert Aldo R.Boccaccini 2018Bioactive Materials2018,3,1:4
12An APXPS endstation for gas–solid and liquid–solid interface studies at SSRF显示文摘In the past few decades, various surface analysis techniques find wide applications in studies of interfacial phenomena ranging from fundamental surface science,catalysis, environmental science and energy materials.With the help of bright synchrotron sources, many of these techniques have been further advanced into novel in-situ/operando tools at synchrotron user facilities, providing molecular level understanding of chemical/electrochemical processes in-situ at gas–solid and liquid–solid interfaces.Designing a proper endstation for a dedicated beamline is one of the challenges in utilizing these techniques efficiently for a variety of user's requests. Many factors,including pressure differential, geometry and energy of the photon source, sample and analyzer, need to be optimized for the system of interest. In this paper, we discuss the design and performance of a new endstation at beamline02 B at the Shanghai Synchrotron Radiation Facility for ambient pressure X-ray photoelectron spectroscopy studies.This system, equipped with the newly developed hightransmission HiPP-3 analyzer, is demonstrated to be capable of efficiently collecting photoelectrons up to 1500 eV from ultrahigh vacuum to ambient pressure of 20 mbar.The spectromicroscopy mode of HiPP-3 analyzer also enables detection of photoelectron spatial distribution with resolution of 2.8 ± 0.3 lm in one dimension. In addition,the designing strategies of systems that allow investigations in phenomena at gas–solid interface and liquid–solid interface will be highlighted through our discussion.Jun Cai Qiao Dong Yong Han Bao-Hua Mao Hui Zhang Patrik G.Karlsson John ?hlund Ren-Zhong Tai Yi Yu Zhi Liu 2019Nuclear Science and Techniques2019,30,5:3
13Superconducting single-photon detectors integrated with diamond nanophotonic circuits显示文摘Photonic quantum technologies hold promise to repeat the success of integrated nanophotonic circuits in non-classical applications.Using linear optical elements,quantum optical computations can be performed with integrated optical circuits and can therefore overcome the existing limitations in terms of scalability.In addition to passive optical devices for realizing photonic quantum gates,active elements,such as single-photon sources and single-photon detectors,are essential ingredients for future optical quantum circuits.Material systems that allow for the monolithic integration of all components are particularly attractive,including III-V semiconductors,silicon and diamond.Here,we demonstrate nanophotonic integrated circuits made from high-quality polycrystalline diamond thin films in combination with on-chip single-photon detectors.By using superconducting nanowires that are coupled evanescently to traveling waves,we achieve high detection efficiencies of up to 66%as well as low dark count rates and a timing resolution of 190 ps.Our devices are fully scalable and hold promise for functional diamond photonic quantum devices.Patrik Rath Oliver Kahl Simone Ferrari Fabian Sproll Georgia Lewes-Malandrakis Dietmar Brink Konstantin Ilin Michael Siegel Christoph Nebel Wolfram Pernice 2015Light(Science & Applications)2015,4,1:3

18Determination of frequencies of oscillations of cloud cavitation on a 2-D hydrofoil from high-speed camera observations显示文摘A method is presented to determine significant frequencies of oscillations of cavitation structures from high-speed camera recordings of a flow around a 2-D hydrofoil. The top view of the suction side of an NACA 2412 hydrofoil is studied in a transparent test section of a cavitation tunnel for selected cloud cavitation regimes with strong oscillations induced by the leading-edge cavity shedding. The ability of the method to accurately determine the dominant oscillation frequencies is confirmed by pressure measurements. The method can resolve subtle flow characteristics that are not visible to the naked eye. The method can be used for noninvasive experimental studies of oscillations in cavitating flows with adequate visual access when pressure measurements are not available or when such measurements would disturb the flow.Patrik ZIMA Tomas FURST Milan SEDLAR Martin KOMAREK Rostislav HUZLIK 2016Journal of Hydrodynamics2016,28,3:2
