4Blockchain-based vehicular edge computing networks:the communication perspective显示文摘Vehicular edge computing(VEC)networks can satisfy the increasing demands of data processing by offloading the computation tasks to multiple distributed edge computing nodes assisted by servers.These edge servers generally combine with roadside units(RSUs).However,RSUs with edge servers cannot be fully trusted,possibly leading to serious security and privacy problems.Combining blockchain with VEC networks may establish a trusted and decentralized vehicular environment,but the coexistence of multiple communication modes comprising vehicle-to-vehicle(V2V),vehicle-to-RSU(V2R),and RSU-to-RSU(R2R)makes the block propagation patterns have different effects on the block consensus process.In this paper,we study the block propagation patterns between vehicles and RSUs with edge servers under three communication modes.We first give the closed-form expressions for the single-block and multiblock propagation times in two specific conditions to explore how the priority of a block generated from a specific node affects the block propagation process,in which multiblock propagation embodies competitive propagation due to blockchain forking.Then,an innovative consensus mechanism that fully invokes the communication capability of the nodes is proposed,and the block propagation time and frequency can be substantially reduced under this mechanism.In addition,an important finding is that under the conventional and proposed consensus mechanisms,an RSU or a vehicle that creates a new block plays a decisive role in the block propagation pattern.Lin HE Fuchang LI Haikun XU Wenbo XIA Xuefei ZHANG Xiaofeng TAO 2023Science China(Information Sciences)2023,66,7:1

8Neglected Aspects of SARS-CoV-2 Aerosol Transmission in Bathrooms of Multistory and High-Rise Buildings—Beijing Municipality,China,October 2022显示文摘Summary What is already known about this topic?There is a toilet flush-soil stack-floor drain pathway of aerosol transmission in multistory and high-rise buildings,but the influencing factors are not completely clear.What is added by this report?The poor airtightness of the connecting parts of the floor drain,as well as pressure fluctuations in the sewage pipe during toilet flushing caused by blockage of the soil stack vent,may lead to the cross-floor transmission of viral aerosols through the soil stack and floor drains.Keyang Lyu Qin Wang Xia Li Zhuona Zhang Xiaoning Zhao Yunpu Li Zhigang Tang Longjian Li Fuchang Deng Xiaoyu Zhang Kaiqiang Xu Rong Zhao Dongqun Xu 2023China CDC weekly2023,5,1:0
9Preparation of sodium molybdate from molybdenum concentrate by microwave roasting and alkali leaching显示文摘The preparation process of sodium molybdate has the disadvantages of high energy consumption,low thermal efficiency,and high raw material requirement of molybdenum trioxide,in order to realize the green and efficient development of molybdenum concentrate resources,this paper proposes a new process for efficient recovery of molybdenum from molybdenum concentrate and preparation of sodium molybdate by microwave-enhanced roasting and alkali leaching.Thermodynamic analysis indicated the feasibility of oxidation roasting of molybdenum concentrate.The effects of roasting temperature,holding time,and power-to-mass ratio on the oxidation product and leaching product sodium molybdate (Na_(2)MoO_(4)·2H_(2)O) were investigated.Under the optimal process conditions:roasting temperature of 700℃,holding time of 110 min,and power-to-mass ratio of 110 W/g,the molybdenum state of existence was converted from MoS_(2) to Mo O3.The process of preparing sodium molybdate by alkali leaching of molybdenum calcine was investigated,the optimal leaching conditions include a solution concentration of 2.5 mol/L,a liquid-to-solid ratio of 2 mL/g,a leaching temperature of 60℃,and leaching solution termination at pH 8.The optimum conditions result in a leaching rate of sodium molybdate of 96.24%.Meanwhile,the content of sodium molybdate reaches 94.08wt%after leaching and removing impurities.Iron and aluminum impurities can be effectively separated by adjusting the pH of the leaching solution with sodium carbonate solution.This research avoids the shortcomings of the traditional process and utilizes the advantages of microwave metallurgy to prepare high-quality sodium molybdate,which provides a new idea for the highvalue utilization of molybdenum concentrate.Fengjuan Zhang Chenhui Liu Srinivasakannan Chandrasekar Yingwei Li Fuchang Xu 2024International Journal of Minerals,Metallurgy and Materials2024,31,1:0
10Independent and Interactive Effects of Environmental Conditions on Aerosolized Surrogate SARS-CoV-2-Beijing,China,June to September 2020显示文摘Summary What is already known about this topic?Environmental factors such as temperature and humidity play important roles in the transmission of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)via droplets/aerosols.What is added by this report?Higher relative humidity(61%–80%),longer spreading time(120 min),and greater dispersal distance(1 m)significantly reduced SARS-CoV-2 pseudovirus loads.There was an interaction effect between relative humidity and spreading time.What are the implications for public health practice?The findings contribute to our understanding of the impact of environmental factors on the transmission of SARS-CoV-2 via airborne droplets/aerosols.Yixin Mao Yueyun Luo Wenda Zhang Pei Ding Xia Li Fuchang Deng Kaiqiang Xu Min Hou Cheng Ding Youbin Wang Zhaomin Dong Raina MacIntyre Xiaoyuan Yao Song Tang Dongqun Xu 2022China CDC weekly2022,4,26:0
11Financial Support for Rural Cooperative Economy in China Based on Grey Correlation Analysis显示文摘This paper firstly analyzed current situations of financial support for rural cooperative economy in China and tested the correlation between rural finance and rural cooperative economy using the grey correlation analysis method. Results indicate that there is a close relationship between amount,structure and efficiency of rural finance and development of rural cooperative economy. The amount of rural finance has the largest promotion function to development of rural cooperative economy,the next is rural finance structure,and the least is efficiency of rural finance. Based on research conclusions,it came up with pertinent policy recommendations.Fuchang XU Chuandong WANG 2015Asian Agricultural Research2015,7,7:0
12Self-Healing Hydrophilic Porous Photothermal Membranes for Durable and Highly Efficient Solar-Driven Interfacial Water Evaporation显示文摘It is highly desirable to develop a solar-driven interfacial water evaporatorwith a self-healing ability and high-efficiency water evaporation performance for water distillation and desalination;however,this process is considerably challenging.Herein,by exploiting the advantages of a self-healing hydrophilic polymer,a self-healing hydrophilic porous photothermal(SHPP)membrane was fabricated by curing a mixture of the polymer,carbon black,and NaCl,followed by removal of the NaCl from water.Since the SHPP membrane could serve as a photothermal layer and water transportation channel simultaneously,a solar-driven interfacial evaporator could be fabricated readily by assembling the SHPP membrane with polyethylene foam.We have shown that the SHPP membrane-based evaporator exhibited a water evaporation rate of 1.68 kg m^(−2) h^(−1) and an energy efficiency of 97.3%.These values are superior to those obtained using solar-driven interfacial evaporators with self-healing capability.Notably,by hydrogen bonds reformation between the fracture surfaces,the SHPP membrane could regain its structural integrity after breaking,making the SHPPmembrane-based evaporator the first to heal entirely and repeatedly from physical damage to sustain itswater evaporation capacity.Therefore,the potential of using SHPP membranes to develop stable,long-last ing,andhigh-efficiency solar-driven interfacial water evaporators is highlighted.Fuchang Xu Dehui Weng Xiang Li Yang Li Junqi Sun 2022CCS Chemistry2022,4,7:0
