| 2 | Establishment of a novel corneal endothelial cell line from domestic rabbit,Oryctolagus curiculus显示文摘To develop a rabbit corneal endothelial (RCE) cell line, in vitro culture of RCE cells was initiated from Oryctolagus curiculus corneas and a novel RCE cell line was established in this study. To initiate the primary culture of RCE cells, corneas from rabbit eyes were sliced and attached into glutin-coated wells with endothelial cell surface down. After being cultured at a time-gradient interval from 48 to 6 h, the corneal slices were detached and reattached into new wells, respectively. Cells in the wells containing only a pure population of RCE cells were collected and cultured in 20% FBS-DMEM/F12 medium con- taining chondroitin sulfate, ocular extract, epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), carboxymethyl-chitosan, N-acetylglucosamine hydrochloride, glucosamine hydrochloride, culture medium of rabbit corneal stromal cells and oxidation-degradation products of chondroitin sul- fate at 37℃, 5% CO2. The cultured RCE cells, in quadrangle and polygonal shapes, proliferated to con- fluence 3 weeks later. During the subsequent subculture, the shape of RCE cells changed gradually from polygonal to more fibroblastic. A novel RCE cell line, growing at a steady rate, with a population doubling time of 53.8 h, has been established and subcultured to passage 67. Chromosome analysis showed that the RCE cells exhibited chromosomal aneuploidy with the modal chromosome number of 44. The results of immuno-cytochemical staining with neuron specific enolase (NSE) confirmed that the RCE cells were in neuroectodermal origin. Combined with the results of vascular endothelial growth factor (VEGF) treatment and endothelial cell morphology recovery, it can be concluded that the cell line established here is an RCE cell line. This RCE cell line may serve as a useful tool in theoretical re- searches of mammalian corneal endothelial cells, and may also have potential application in artificial corneal endothelium development. | FAN TingJun, ZHAO Jun, FU YongFeng, CONG RiShan, GUO RuiChao, LIU WanShun, HAN BaoQin, YU QiuTao & WANG JingCollege of Marine Life Sciences, Division of Life Science and Technology, Ocean University of China, Qingdao 266003, China | 2007 | Science China(Life Sciences)2007，50，2： | 15 |
| 3 | Review:Recent advances in multisensor multitarge11racking using random finite set显示文摘In this study,we provide an overview of recent advances in multisensor multitarget tracking based on the random finite set(RFS)approach.The fusion that plays a fundamental role in multisensor filtering is classified into data-level multitarget measurement fusion and estimate-level multitarget density fusion,which share and fuse local measurements and posterior densities between sensors,respectively.Important properties of each fusion rule including the optimality and sub-optimality are presented.In particulax,two robust multitarget density-averaging approaches,arithmetic-and geometric-average fusion,are addressed in detail for various RFSs.Relevant research topics and remaining challenges are highlighted. | Kai DA Tiancheng LI Yongfeng ZHU Hongqi FAN Qiang FU | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，1： | 5 |
| 4 | Prediction of the anti-inflammatory mechanisms of curcumin by module-based protein interaction network analysis显示文摘Curcumin,the medically active component from Curcuma longa(Turmeric),is widely used to treat inflammatory diseases.Protein interaction network(PIN) analysis was used to predict its mechanisms of molecular action.Targets of curcumin were obtained based on ChE MBL and STITCH databases.Protein–protein interactions(PPIs) were extracted from the String database.The PIN of curcumin was constructed by Cytoscape and the function modules identified by gene ontology(GO) enrichment analysis based on molecular complex detection(MCODE).A PIN of curcumin with 482 nodes and 1688 interactions was constructed,which has scale-free,small world and modular properties.Based on analysis of these function modules,the mechanism of curcumin is proposed.Two modules were found to be intimately associated with inflammation.With function modules analysis,the anti-inflammatory effects of curcumin were related to SMAD,ERG and mediation by the TLR family.TLR9 may be a potential target of curcumin to treat inflammation. | Yanxiong Gan Shichao Zheng Jan P.A.Baak Silei Zhao Yongfeng Zheng Nini Luo Wan Liao Chaomei Fu | 2015 | Acta Pharmaceutica Sinica B2015，5，6： | 5 |
| 5 | Climate and meteorological processes of the East Antarctic ice sheet between Zhongshan and Dome-A显示文摘The 1228 km over-snow traverse route between the Chinese Zhongshan Station,on the coast of Prydz Bay,and Dome-A,at 4091 m elevation the highest point of the East Antarctic ice sheet,has been the focus of CHINARE surface meteorological and climate studies since 2002.A network of seven Automatic Weather Stations has been deployed along this section,including at Dome-A itself,and some of these have now provided nearly-hourly data for over a decade.Atmospheric boundary layer turbulence and radiation observations have been made over the near-coastal ice sheet inland of Zhongshan and surface turbulence measurements using an ultrasonic anemometer system have also been made in the deep interior of the ice sheet.Summer GPS radiosonde soundings of the atmospheric boundary layer have been made at Kunlun Station,near Dome-A.In this paper these observations are combined to provide a comprehensive overview of the meteorological regime of this region of the ice sheet,its climate variability,and as a reference for future study of climate change.This includes investigation of the variation of surface climate features with elevation and distance from the coast,the height and structure of the boundary layer over the ice sheet,and seasonal and regional changes in ice/snow-air interactions,including turbulent and radiative energy fluxes.The air temperature and snow temperature between the coastal Zhongshan and Dome-A on the inland plateau have not changed significantly in the past decade compared with the inter-annual variability. | BIAN Lingen Ian Allison XIAO Cunde MA Yongfeng FU Liang DING Minghu | 2016 | Advances in Polar Science2016，27，2： | 4 |
| 6 | Colour compound lenses for a portable fluorescence microscope显示文摘In this article,we demonstrated a handheld smartphone fluorescence microscope(HSFM)that integrates dualfunctional polymer lenses with a smartphone.The HSFM consists of a smartphone,a field-portable illumination source,and a dual-functional polymer lens that performs both optical imaging and filtering.Therefore,compared with the existing smartphone fluorescence microscope,the HSFM does not need any additional optical filters.Although fluorescence imaging has traditionally played an indispensable role in biomedical and clinical applications due to its high specificity and sensitivity for detecting cells,proteins,DNAs/RNAs,etc.,the bulky elements of conventional fluorescence microscopes make them inconvenient for use in point-of-care diagnosis.The HSFM demonstrated in this article solves this problem by providing a multifunctional,miniature,small-form-factor fluorescence module.This multifunctional fluorescence module can be seamlessly attached to any smartphone camera for both bright-field and fluorescence imaging at cellular-scale resolutions without the use of additional bulky lenses/filters;in fact,the HSFM achieves magnification and light filtration using a single lens.Cell and tissue observation,cell counting,plasmid transfection evaluation,and superoxide production analysis were performed using this device.Notably,this lens system has the unique capability of functioning with numerous smartphones,irrespective of the smartphone model and the camera technology housed within each device.As such,this HSFM has the potential to pave the way for realtime point-of-care diagnosis and opens up countless possibilities for personalized medicine. | Bo Dai Ziao Jiao Lulu Zheng Hunter Bachman Yongfeng Fu Xinjun Wan Yule Zhang Yu Huang Xiaodian Han Chenglong Zhao Tony Jun Huang Songlin Zhuang Dawei Zhang | 2019 | Light(Science & Applications)2019，8，1： | 3 |
| 7 | Completely spin-decoupled geometric phase of a metasurface显示文摘Metasurfaces have provided an unprecedented degree of freedom(DOF)in the manipulation of electromagnetic waves.A geometric phase can be readily obtained by rotating the meta-atoms of a metasurface.Nevertheless,such geometric phases are usually spin-coupled,with the same magnitude but opposite signs for left-and right-handed circularly polarized(LCP and RCP)waves.To achieve independent control of LCP and RCP waves,it is crucial to obtain spin-decoupled geometric phases.In this paper,we propose to obtain completely spin-decoupled geometric phases by engineering the surface current paths on meta-atoms.Based on the rotational Doppler effect,the rotation manner is first analyzed,and it is found that the generation of a geometric phase lies in the rotation of the surface current paths on meta-atoms.Since the induced surface current paths under the LCP and RCP waves always start oppositely and are mirror-symmetrical with each other,it is natural that the geometric phases have the same magnitude and opposite signs when the meta-atoms are rotated.To obtain spin-decoupled geometric phases,the induced surface current under one spin should be rotated by one angle while the current under the other spin is rotated by a different angles.In this way,LCP and RCP waves can acquire different geometric phase changes.Proof-of-principle prototypes were designed,fabricated,and measured.Both the simulation and experiment results verify spin-decoupled geometric phases.This work provides a robust means to obtain a spindependent geometric phase and can be readily extended to higher frequency bands such as the terahertz,IR,and optical regimes. | XINMIN FU JIE YANG JIAFU WANG YAJUAN HAN CHANG DING TIANSHUO QIU BINGYUE QU LEI LI YONGFENG LI SHAOBO QU | 2023 | Photonics Research2023，11，7： | 1 |
| 8 | Fractal detector design and application in maritime target detection显示文摘The fractal properties of sea clutter are proposed and applied to the maritime target detection. Calculation of the measured data shows that, the Hurst exponent of the sea clutter with targets and the sea clutter without targets are different, which enables us to detect low-observable targets within the sea clutter.This paper explains the reason why the Hurst exponent can distinguish the presence or absence of targets in theory and proposes a fractal detector based on the Hurst exponent. Comparing the fractal detector proposed in this paper to the energy detector by the detection results of 140 frames data of the real sea clutter, it is demonstrated that the fractal detection method has a better detection performance. In order to get systemic conclusions, the new sea clutter data with different signal-to-clutter ratios(SCRs) are constructed in the way that add the sea clutter data with targets to the pure sea clutter data. The results show that the fractal detection method has a better performance than the statistical method on detection of maritime targets, especially maritime weak targets with low SCR. | Xinglin Shen Zhiyong Song Yongfeng Zhu Qiang Fu | 2017 | Journal of Systems Engineering and Electronics2017，28，1： | 1 |

| 13 | Macroscopic superlubricity of potassium hydroxide solution achieved by incorporating in-situ released graphene from friction pairs显示文摘Graphene(G),as a typical two-dimensional material,is often used as an additive for liquid lubricants.However,graphene is mostly added to liquid lubricants in a one-time manner in friction;it mainly exists in the form of multilayer agglomerated structures due to theπ–πstacking between graphene sheets,making it unable to fully exert the synergistic lubrication function.Herein,we propose a new macroscopic superlubric system of graphene/potassium hydroxide(G/KOH)solution;and the graphene additive involved is exfoliated in-situ from graphene/epoxy(G/EP)friction pair by friction,continuously providing freshly-peeled graphene into KOH solution and minimizing the adverse effects of graphene agglomeration.Moreover,the in-situ produced graphene additive has thinner thickness and better anti-aggregation ability,which provide more graphene to accommodate OH−,form more stacked sandwich structures of OH−/graphene/OH−between friction pairs(i.e.,equivalent to a moving pulley block with more wheels),and finally realize superlubricity.This study develops a new liquid superlubric system suitable for alkaline environments,and at the same time proposes a new way to gradually release graphene additives in situ,rather than adding them all at once,deepening the understanding to liquid superlubricity mechanism,and paving the experimental foundation for the practical application of macroscopic superlubricity. | Hongyu LIANG Xinjie CHEN Yongfeng BU Meijuan XU Gang ZHENG Kaixiong GAO Xijun HUA Yonghong FU Junyan ZHANG | 2023 | Friction2023，11，4： | 0 |
| 14 | Dynamic analysis of geared transmission system for wind turbines with mixed aleatory and epistemic uncertainties显示文摘This paper deals with the co-existence of mixed aleatory and epistemic uncertainties in a wind turbine geared system for more reliable and robust vibration analyses.To this end,the regression-based polynomial chaos expansion(PCE)is used to track aleatory uncertainties,and the polynomial surrogate approach(PSA)is developed to treat the epistemic uncertainties.This non-intrusive dual-layer framework shares the same collocation pool,which is extracted from the Legendre series.Moreover,the regression technique has been implemented in both layers to enhance calculation efficiency.Numerical validation is carried out to show the effectiveness of the proposed method.New vibration behaviors of the geared transmission system are observed,and the mechanism behind is discussed in detail.The findings of this paper will contribute to the insightful understanding of such wind turbine geared systems under hybrid uncertainties and are beneficial for the condition monitoring. | Chao FU Kuan LU Y.D.XU Yongfeng YANG F.S.GU Yushu CHEN | 2022 | Applied Mathematics and Mechanics(English Edition)2022，43，2： | 0 |
| 15 | A QoT prediction technique based on machine learning and NLSE for QoS and new lightpaths in optical communication networks显示文摘In this paper,we proposed a quality of transmission(QoT)prediction technique for the quality of service(QoS)link setup based on machine learning classifiers,with synthetic data generated using the transmission equations instead of the Gaussian noise(GN)model.The proposed technique uses some link and signal characteristics as input features.The bit error rate(BER)of the signals was compared with the forward error correction threshold BER,and the comparison results were employed as labels.The transmission equations approach is a better alternative to the GN model(or other similar margin-based models)in the absence of real data(i.e.,at the deployment stage of a network)or the case that real data are scarce(i.e.,for enriching the dataset/reducing probing lightpaths);furthermore,the three classifiers trained using the data of the transmission equations are more reliable and practical than those trained using the data of the GN model.Meanwhile,we noted that the priority of the three classifiers should be support vector machine(SVM)>K nearest neighbor(KNN)>logistic regression(LR)as shown in the results obtained by the transmission equations,instead of SVM>LR>KNN as in the results of the GN model. | Yongfeng FU Jing CHEN Weiming WU Yu HUANG Jie HONG Long CHEN Zhongbin LI | 2021 | Frontiers of Optoelectronics2021，14，4： | 0 |
| 16 | Full-scale evaluation of reversed A^(2)/O process for removal of multiple pollutants in sewage显示文摘This study evaluated the removal of multiple pollutants,i.e.,polybrominated diphenyl ethers(PBDEs),novel halogenated flame retardants(HFRs),sulfonamide antibiotics(SAs),and heavy metals(HMs),by a fullscale reversed A^(2)/O process in a sewage treatment plant(STP)in Guangzhou,China.The reversed A^(2)/O process demonstrated high removal efficiencies(REs)for total PBDEs(60.5%±4.3%),novel HFRs(98.4%±2.8%)and HMs(70.1%±1.2%),and a relatively low RE for SAs(25.0%±2.3%).BDE 209,the dominant PBDE congener,showed a high residual concentration(13.41±5.18 ng/L)in the suspended particulate matter(SPM)of treated effluents.So me novel HFRs,dechlorane plus(DP)and decabromodiphe nyl ethane(DBDPE),were detected in the SPM of the raw sewage(7.50±4.14 ng/L and 11.52±11.65 ng/L,respectively).The removal ofSAs was mainly through biodegradation in the activated sludge bioreactors(ASBs).Ofthe HMs,Mn and Ni exhibited the lowest REs(47.5%±2.2%and 35.0%±2.6%,respectively),while Cr and Cu showed the highest removal(REs>80%).In terms of treatment units in the reversed A^(2)/O process,ASBs showed the highest RE(27.8%)for the multiple pollutants.The information can aid in our understanding of removal properties of STPs on various pollutants and evaluating the ecological/health risks of STPs as point pollutant sources. | Qihang Wu Haiyan Li Xiaodong Hu Yongfeng Shi Deguan Kong Yucheng Zhang Bixian Mai Dongye Zhao Jie Fu | 2020 | Chinese Chemical Letters2020，31，10： | 0 |
| 17 | Characterizing nitric oxide emissions from two typical alpine ecosystems显示文摘portion of alpine meadows has been and will continue to be cultivated due to the concurrent increasing demands for animal-and crop-oriented foods and global warming.However, it remains unclear how these long-term changes in land use will affect nitric oxide(NO) emission. At a field site with a calcareous soil on the Qinghai-Tibetan Plateau,the authors measured the year-round NO fluxes and related variables in a typically wintergrazed natural alpine meadow(NAM) and its adjacent forage oat field(FOF). The results showed that long-term plow tillage, fertilization and growing forage oats significantly yielded ca. 2.7 times more(p < 0.01) NO emissions from the FOF than the NAM(conservatively 208 vs. 56 g N/(ha·year) on average). The spring freeze–thaw period and non-growing season accounted for 17%-35% of the annual emissions, respectively. The Q10 of surface soil temperature(Ts) was 8.9 in the NAM(vs. 3.8 in the FOF), indicating increases of 24%–93% in NO emissions per 1–3 °C increase. However, the warming-induced increases could be smaller than those due to land use change and management practices. The Tsand concentrations of ammonium, nitrate and water-extractable organic carbon jointly explained 69% of the variance in daily NO fluxes from both fields during the annual period(p < 0.001). This result indicates that temporally and/or spatially distributed NO fluxes from landscapes with calcareous soils across native alpine meadows and/or fields cultivated with forage oats can be predicted by simultaneous observations of these four soil variables. | Fei Lin Chunyan Liu Xiaoxia Hu Yongfeng Fu Xunhua Zheng Rui Wang Wei Zhang Guangmin Cao | 2019 | Journal of Environmental Sciences2019，31，3： | 0 |
