| 1 | High current density Sc_2O_3-W matrix dispenser cathode显示文摘Sc2O3-W matrix dispenser cathodes have been prepared by powder metallurgy method and tested in Pierce electron guns.The emission current density can reach 72 A/cm2 at 900C and over 100 A/cm2 can be achieved at a temperature higher than 950C.The emission improves and then keeps stable with time throughout the life testing period of 330 h at a continuous loading of 88 A/cm2pulsed current density with a pulse width of 10μs and duty cycle of 0.2%.The cathode surface is covered by a semiconductor multilayer composed of Ba,Sc and O.The emission behavior of the cathode can be explained by a semiconductor model. | WANG JinShu ZHANG XiZhu LIU Wei WANG YiMan ZHOU MeiLing ZUO TieYong | 2012 | Science China(Information Sciences)2012，55，1： | 7 |
| 2 | A review on scandia doped tungsten matrix scandate cathode显示文摘As the cathode with the highest electron emission capability in the thermionic cathode,the scandate cathode has attracted more and more attention in recent years,especially the scandia doped tungsten matrix scandate cathode.Experimental studies show that scandia doped tungsten matrix scandate cathodes with submicron microstructures exhibit excellent emission capacity,and the pulse emission current density in the space-charge region can be over 35 A cm^(−2) at 850°Cb.In the direct current(DC)condition with temperature compensation,the emission current density could reach 25 A cm^(−2) at 850°Cb.The device lifetime is over 3700 h after operating at 950°C_(b) with the DC loading of 40 A cm^(−2).The emission mechanism of the scandate cathode including the effect of the surface structure and composition on the work function of the cathode are systematically reviewed. | Jinshu Wang Yunfei Yang Yiman Wang Wei Liu Meiling Zhou Tieyong Zuo | 2019 | Tungsten2019，1，1： | 5 |
| 3 | Urban air quality, meteorology and traffic linkages: Evidence from a sixteen-day particulate matter pollution event in December 2015, Beijing显示文摘A heavy 16-day pollution episode occurred in Beijing from December 19, 2015 to January 3,2016. The mean daily AQI and PM_(2.5) were 240.44 and 203.6 μg/m^3. We analyzed the spatiotemporal characteristics of air pollutants, meteorology and road space speed during this period, then extended to reveal the combined effects of traffic restrictions and meteorology on urban air quality with observational data and a multivariate mutual information model. Results of spatiotemporal analysis showed that five pollution stages were identified with remarkable variation patterns based on evolution of PM_(2.5) concentration and weather conditions. Southern sites(DX, YDM and DS) experienced heavier pollution than northern ones(DL, CP and WL). Stage P2 exhibited combined functions of meteorology and traffic restrictions which were delayed peak-clipping effects on PM_(2.5).Mutual information values of Air quality–Traffic–Meteorology(ATM–MI) revealed that additive functions of traffic restrictions, suitable relative humidity and temperature were more effective on the removal of fine particles and CO than NO_2. | Dongmei Hu Jianping Wu Kun Tian Lyuchao Liao Ming Xu Yiman Du | 2017 | Journal of Environmental Sciences2017，29，9： | 3 |

| 5 | CmBES1 is a regulator of boundary formation in chrysanthemum ray florets显示文摘Chrysanthemum(Chrysanthemum morifolium)is an ideal model species for studying petal morphogenesis because of the diversity in the flower form across varieties;however,the molecular mechanisms underlying petal development are poorly understood.Here,we show that the brassinosteroid transcription factor BRI1-EMS-SUPPRESSOR 1(CmBES1)in chrysanthemum(C.morifolium cv.Jinba)is important for organ boundary formation because it represses organ boundary identity genes.Chrysanthemum plants overexpressing CmBES1 displayed increased fusion of the outermost ray florets due to the loss of differentiation of the two dorsal petals,which developed simultaneously with the ventral petals.RNA-seq analysis of the overexpression lines revealed potential genes and pathways involved in petal development,such as CUP-SHAPED COTYLEDON(CUC2),CYCLOIDEA 4(CYC4),genes encoding MADS-box transcription factors and homeodomain-leucine zippers(HD-Zips)and auxin pathway-related genes.This study characterizes the role of CmBES1 in ray floret development by its modulation of flower development and boundary identity genes in chrysanthemum. | Peilei Cheng Yanan Liu Yiman Yang Hong Chen Hua Cheng Qian Hu Zixin Zhang Jiaojiao Gao Jiaxin Zhang Lian Ding Weimin Fang Sumei Chen Fadi Chen Jiafu Jiang | 2020 | Horticulture Research2020，7，1： | 2 |

| 11 | Deciphering spike architecture formation towards yield improvement in wheat显示文摘Wheat is the most widely grown crop globally,providing 20%of the daily consumed calories and protein content around the world.With the growing global population and frequent occurrence of extreme weather caused by climate change,ensuring adequate wheat production is essential for food security.The archi-tecture of the inflorescence plays a crucial role in determining the grain number and size,which is a key trait for improving yield.Recent advances in wheat genomics and gene cloning techniques have improved our understanding of wheat spike development and its applications in breeding practices.Here,we summarize the genetic regulation network governing wheat spike formation,the strategies used for identifying and studying the key factors affecting spike architecture,and the progress made in breeding applications.Additionally,we highlight future directions that will aid in the regulatory mechanistic study of wheat spike determination and targeted breeding for grain yield improvement. | Xumei Luo Yiman Yang Xuelei Lin Jun Xiao | 2023 | Journal of Genetics and Genomics2023，50，11： | 1 |

| 16 | Predicting vehicle fuel consumption patterns using floating vehicle data显示文摘The status of energy consumption and air pollution in China is serious. It is important to analyze and predict the different fuel consumption of various types of vehicles under different influence factors. In order to fully describe the relationship between fuel consumption and the impact factors, massive amounts of floating vehicle data were used.The fuel consumption pattern and congestion pattern based on large samples of historical floating vehicle data were explored, drivers' information and vehicles' parameters from different group classification were probed, and the average velocity and average fuel consumption in the temporal dimension and spatial dimension were analyzed respectively.The fuel consumption forecasting model was established by using a Back Propagation Neural Network. Part of the sample set was used to train the forecasting model and the remaining part of the sample set was used as input to the forecasting model. | Yiman Du Jianping Wu Senyan Yang Liutong Zhou | 2017 | Journal of Environmental Sciences2017，29，9： | 1 |
| 17 | CmRCD1 represses flowering by directly interacting with CmBBX8 in summer chrysanthemum显示文摘The CmBBX8-CmFTL1 regulatory module is a key determinant in the transition from vegetative growth to reproductive development in summer-flowering chrysanthemum.However,the detailed regulatory mechanism of CmBBX8-mediated flowering remains elusive.In this study,we revealed that RADICAL-INDUCED CELL DEATH 1(CmRCD1)physically associated with CmBBX8 through bimolecular fluorescence complementation(BiFC),pulldown and Coimmunoprecipitation(CoIP)assays.Furthermore,the RCD1-SRO1-TAF4(RST)domain of CmRCD1 and the B-box of CmBBX8 mediated their interaction.In addition,Luciferase(LUC)assays and electrophoretic mobility shift assay(EMSAs)showed that CmRCD1 repressed the transcriptional activity of CmBBX8 and interfered with its binding to the CmFTL1 promoter,thereby leading to delayed flowering in the summer chrysanthemum‘Yuuka’.These results provide insight into the molecular framework of CmRCD1-CmBBX8-mediated flowering in chrysanthemum. | Lijun Wang Hua Cheng Qi Wang Chaona Si Yiman Yang Yao Yu Lijie Zhou Lian Ding Aiping Song Dongqing Xu Sumei Chen Weimin Fang Fadi Chen Jiafu Jiang | 2021 | Horticulture Research2021，8，1： | 1 |
