1Aerosol light absorption in a coastal city in Southeast China:Temporal variations and implications for brown carbon显示文摘Light-absorbing carbonaceous aerosols including black carbon(BC) and brown carbon(BrC)play significant roles in atmospheric radiative properties. One-year measurements of aerosol light absorption at multi-wavelength were continuously conducted in Xiamen,southeast of China in 2014 to determine the light absorption properties including absorption coefficients(σabs) and absorption ?ngstr?m exponent(AAE) in the coastal city.Light absorptions of BC and BrC with their contributions to total light absorption were further quantified. Mean σabsat 370 nm and 880 nm were 56.6 ± 34.3 and 16.5 ± 11.2 Mm-1,respectively. σabspresented a double-peaks diurnal pattern with the maximum in the morning and the minimum in the afternoon. σabswas low in warm seasons and high in cold seasons. AAE ranged from 0.26 to 2.58 with the annual mean of 1.46, implying that both fossil fuel combustion and biomass burning influenced aerosol optical properties. σabsof BrC at 370 nm was 24.0 ± 5.7 Mm-1, contributing 42% to the total absorption. The highest AAE(1.52 ± 0.02) and largest BrC contributions(47% ± 4%) in winter suggested the significant influence of biomass burning on aerosol light absorption. Long-distance air masses passing through North China Plain and the Yangtze River Delta led to high AAE and BrC contributions. High AAE value of 1.46 in July indicated that long-range transport of the air pollutants from intense biomass burning in Southeast Asia would affect aerosol light absorption in Southeast China. The study will improve the understanding of light absorption properties of aerosols and the optical impacts of BrC in China.Yuqing Qiu Xin Wu Yanru Zhang Lingling Xu Youwei Hong Jinsheng Chen Xiaoqiu Chen Junjun Deng 2019Journal of Environmental Sciences2019,31,6:5

6Effect of grain boundary segregation on aging resistance and mechanical properties of tetravalent element-doped 3Y-TZP ceramics for dental restoration显示文摘In the humid oral environment,3Y-TZP ceramics always suffer from low-temperature degradation(LTD)for a long time,which results in the degradation of mechanical properties and catastrophic failure.The low-temperature degradation(LTD)and mechanical properties of low-cost tetravalent(Ge^(4+),Ti^(4+))element-doped 3Y-TZP were investigated by analysing grain boundary segregation in samples with deferent contents.The results show that GeO_(2) is superior to TiO_(2) in limiting LTD but results in lower flexural strength and fracture toughness when the content is≥1.5 mol%.This dilemma can be improved by adding only 0.1%-0.5 wt%Al_(2)O_(3),and the flexural strength and fracture toughness of 0.25 wt% Al_(2)O_(3) zirconia are then increased to 898 MPa and 4.68 MPa·m^(1/2) compared with 1Ge-3Y,respectively.This work is expected to provide an effective reference for the development and application of budget dental materials.Bin Deng Rongfang Zou Yang Huang Lu Feng Yanru Chen 2023International Journal of Smart and Nano Materials2023,14,2:0
7Deep Learning-Based Semantic Feature Extraction:A Literature Review and Future Directions显示文摘Semantic communication,as a critical component of artificial intelligence(AI),has gained increasing attention in recent years due to its significant impact on various fields.In this paper,we focus on the applications of semantic feature extraction,a key step in the semantic communication,in several areas of artificial intelligence,including natural language processing,medical imaging,remote sensing,autonomous driving,and other image-related applications.Specifically,we discuss how semantic feature extraction can enhance the accuracy and efficiency of natural language processing tasks,such as text classification,sentiment analysis,and topic modeling.In the medical imaging field,we explore how semantic feature extraction can be used for disease diagnosis,drug development,and treatment planning.In addition,we investigate the applications of semantic feature extraction in remote sensing and autonomous driving,where it can facilitate object detection,scene understanding,and other tasks.By providing an overview of the applications of semantic feature extraction in various fields,this paper aims to provide insights into the potential of this technology to advance the development of artificial intelligence.DENG Letian ZHAO Yanru 2023ZTE Communications2023,21,2:0
8Feasibility of condensate water recycle of split air handling unit in Chinese University buildings显示文摘Recycling the condensate water of the air conditioner could be explored as an alternative water source to con-tribute to building the green campus.This paper explored the condensate water production through actual mea-surement based on a split air handling unit(SAHU)in a university building.Then,the statistical analysis was used to analyze the recycling feasibility and the impact factors of the condensate water production in 31 Chinese provincial capital cities to obtain the recycling potential map of the condensate water generated from a SAHU.Results showed that:(1)In the measurement,the amount of condensate water produced by a single split air conditioner was 1.6 kg from 12:40 to 13:40.Therefore,the daily output of condensate water of the air condi-tioner with the university operation schedule could reach 52.99 kg during the main air-conditioning season.(2)Among the 31 provincial capital cities in China,the largest condensate water outputs could be found in the Hot Summer and Warm Winter zone and the Hot Summer and Cold Winter zone,with an average monthly output of 1600 kg and 1100 kg,respectively.(3)Regression analysis showed that the dry-bulb temperature and dew point temperature of outdoor air had the highest positive and significant influence on condensate water production.The objective of this study is to provide theoretical guidance for the design and energy conservation evaluation of the feasibility of SAHU condensate water recycling in universities.Xiang Deng Yiyun Shen Senwang Yang Jingyang Feng Si Wang Dongyue Li Yanru Li 2024Energy and Built Environment2024,5,2:0
9Is the Urban Shrinkage Inhibits the Improvement of Public Service Level?显示文摘Public services provide convenient conditions for urban residents to study,work and live,and have important significance for improving the life quality of residents and improving the level of welfare.However,while China’s spatial economic is heading towards agglomeration development,a large number of cities have shrunk,which has made unbalanced supply of public services between regions increasingly prominent.Based on the existing literature and the development reality,this paper analyzes the impact of urban shrinkage on the public service level from the public service supply mechanism,and discusses the heterogeneous effects of different labor shrinkage on public services.The results of the study show that urban shrinkage will inhibit the improvement of public service level,but inter-governmental competition makes the labor shrinkage of industry and service industry promote the improvement of public service level.In addition,this paper takes economic development level as a moderating variable to study the moderating effect of economic development level in the impact of urban shrinkage on public service levels.It is found that the reduction of economic development level will promote government competition and provide more public services.Yanru Deng Mingdou Zhang 2020Journal of Business Administration Research2020,3,3:0
