1Effects of drip irrigation modes on growth and physiological characteristics of Arabica coffee under different N levels显示文摘The objective of this study was to obtain the water-saving and efficient production mode of Arabica coffee. The effects of three drip irrigation modes,conventional drip irrigation( CDI),alternate drip irrigation( ADI) and fixed drip irrigation( FDI) on growth,photosynthetic characteristics,biomass accumulation and irrigation water use efficiency of Arabica coffee were investigated under three nitrogen levels,high nitrogen( NH),middle nitrogen( NM) and low nitrogen( NL). The results show that there was a significant Logistic curve between the plant height,the stem diameter of Arabica coffee and growth days. Compared with CDI,ADI had no significant effects on leaf net photosynthetic rate,stomatal conductance,instantaneous water use efficiency and biomass accumulation above ground of Arabica coffee,while FDI decreased significantly,ADI and FDI increased irrigation water use efficiency by 50. 59% and 32. 85%,respectively. Compared with NH,with the reduction of N application rate,net photosynthetic rate,stomatal conductance,biomass accumulation above ground and irrigation water use efficiency decreased by 6. 81%-12. 30%,13. 70%-22. 69%,9. 61%-16. 67% and 9. 78%-15. 64%,respectively. Compared with CDINH,ADINHdecreased net photosynthesis rate and the stomatal conductance not significantly,other treatments decreased by 9. 16%-19. 22%,14. 49%-32. 91%,and decreased biomass accumulation above ground by 8. 26%-27. 34% except ADINH,and increased irrigation water use efficiency by 16. 46%-60. 95% except CDINMand CDINL. Therefore,alternate drip irrigation under high N level( ADINH) is the best water and nitrogen coupling mode of young Arabica coffee tree for water efficiency.HAO Kun LIU Xiaogang HAN Zhihui WU Helin YU Ning LIU Yanwei YANG Qiliang 2017排灌机械工程学报2017,35,10:3
2Attribute-Based Worker Selection Scheme by Using Blockchain in Decentralized Crowdsourcing Scenario显示文摘Traditional crowdsourcing based on centralized management platform is vulnerable to Distributed denial of service(DDo S)attack and single point of failure.Combining blockchain technology with crowdsourcing can well solve the above problems,enabling users to realize peer-to-peer transactions and collaboration based on decentralized trust in distributed systems where nodes do not need to trust each other.Although the current methods have solved the above problems,task publishers select workers based on their reputation values,which has two disadvantages:subjectivity and difficulty in initial value setting.Due to the complexity of crowdsourcing network,there will be malicious users in the network.The requirement for anonymity protects both legitimate and malicious users.In order to solve these problems,we propose an attribute-based worker selection scheme using the private set intersection technology.Our scheme also realizes the malicious user identity disclosure function.A concrete example of our scheme is given.YANG Qiliang ZHANG Mingrui ZHOU Yanwei YU Yong 2021Chinese Journal of Electronics2021,30,2:1

5Tribological Mechanism of Graphene and Ionic Liquid Mixed Fluid on Grinding Interface under Nanofluid Minimum Quantity Lubrication显示文摘Graphene has superhigh thermal conductivity up to 5000 W/(m·K),extremely thin thickness,superhigh mechanical strength and nano-lamellar structure with low interlayer shear strength,making it possess great potential in mini-mum quantity lubrication(MQL)grinding.Meanwhile,ionic liquids(ILs)have higher thermal conductivity and better thermal stability than vegetable oils,which are frequently used as MQL grinding fluids.And ILs have extremely low vapor pressure,thereby avoiding film boiling in grinding.These excellent properties make ILs also have immense potential in MQL grinding.However,the grinding performance of graphene and ionic liquid mixed fluid under nano-fluid minimum quantity lubrication(NMQL),and its tribological mechanism on abrasive grain/workpiece grinding interface,are still unclear.This research firstly evaluates the grinding performance of graphene and ionic liquid mixed nanofluids(graphene/IL nanofluids)under NMQL experimentally.The evaluation shows that graphene/IL nanofluids can further strengthen both the cooling and lubricating performances compared with MQL grinding using ILs only.The specific grinding energy and grinding force ratio can be reduced by over 40%at grinding depth of 10μm.Work-piece machined surface roughness can be decreased by over 10%,and grinding temperature can be lowered over 50℃at grinding depth of 30μm.Aiming at the unclear tribological mechanism of graphene/IL nanofluids,molecular dynamics simulations for abrasive grain/workpiece grinding interface are performed to explore the formation mechanism of physical adsorption film.The simulations show that the grinding interface is in a boundary lubrication state.IL molecules absorb in groove-like fractures on grain wear flat face to form boundary lubrication film,and graphene nanosheets can enter into the grinding interface to further decrease the contact area between abrasive grain and workpiece.Compared with MQL grinding,the average tangential grinding force of graphene/IL nanofluids can decrease up to 10.8%.The interlayer shear effect and low interlayer shear strength of graphene nanosheets are the principal causes of enhanced lubricating performance on the grinding interface.EDS and XPS analyses are further carried out to explore the formation mechanism of chemical reaction film.The analyses show that IL base fluid happens chemical reactions with workpiece material,producing FeF_(2),CrF_(3),and BN.The fresh machined surface of workpiece is oxidized by air,producing NiO,Cr_(2)O_(3) and Fe_(2)O_(3).The chemical reaction film is constituted by fluorides,nitrides and oxides together.The combined action of physical adsorption film and chemical reaction film make graphene/IL nano-fluids obtain excellent grinding performance.Dexiang Wang Yu Zhang Qiliang Zhao Jingliang Jiang Guoliang Liu Changhe Li 2023Chinese Journal of Mechanical Engineering2023,36,4:0

7A CRISPR activation screen identifies genes that enhance SARS-CoV-2 infection显示文摘Dear Editor,Identifying the host factors that are utilized for virus infection and mapping their cell-type expression profile can help to understand the viral tissue/organ tropism and pathogenesis.Much effort has been devoted to the identification of SARS-CoV-2 infection-dependent host factors.CRISPR-based activation(Konermann et al.,2015).Fei Feng Yunkai Zhu Yanlong Ma Yuyan Wang Yin Yu Xinran Sun Yuanlin Song Zhugui Shao Xinxin Huang Ying Liao Jingyun Ma Yuping He Mingyuan Wang Longhai Tang Yaowei Huang Jincun Zhao Qiang Ding Youhua Xie Qiliang Cai Hui Xiao Chun Li Zhenghong Yuan Rong Zhang 2023Protein & Cell2023,14,1:0
8Grading Evaluation and Ranking of CO_(2) Sequestration Capacity in Place(CSCIP) in China’s Major Oil Basins:Theoretical,Effective,Practical and CCUS-EOR显示文摘Because it is necessary to focus on differences in regional oil reservoirs and determine the priority of the CCUSEOR(Carbon capture,utilization,and storage-enhanced oil recovery) deployment under China’s net-zero CO_(2) emission target,systematic and regional evaluations of CO_(2) sequestration capacity in major oil basins are needed considering the geofluid properties―carbon sequestration capacity in place(CSCIP)―where the ’in place’ indicates actual geological formation conditions underground,e.g.,formation temperature and pressure.Therefore,physical properties of geofluids at different depths with different geologic temperatures and pressure conditions are considered for the CO_(2) sequestration capacity evaluation in place,including shallow(800–2000 m),medium(2000–3500 m),deep(3500–4500 m) and ultra-deep(4500–8000 m) depth intervals.A modified evaluation model with four grading levels is proposed,combining the P-V-T equations of state(EOS) and evaluation equations of the Carbon Sequestration Leadership Forum(CSLF),including theoretical,effective,practical,and CCUS-EOR CSCIP,which is more consistent with geofluid physical properties underground,to make the grading evaluation and ranking of the CSCIP in China’s major oil basins.Then,the grading CSCIP of 29 major oil basins in China was evaluated based on the petroleum resources evaluation results of the Ministry of Natural Resources of China(MNRC) during China’s 13th Five-Year Plan period.According to the grading evaluation results,suggestions for China’s CCUS-EOR prospective regions are given as follows:shallow oil fields of the Songliao Basin in Northeast China,shallow–medium oil fields of the Bohai Bay Basin in East China,medium oil fields of the Zhungeer Basin in West China,and medium oil fields of the Ordos Basin in Central China;all are potential areas for the CCUS-EOR geological sequestration in China’s onshore oil basins.In addition,in China’s offshore oil basins,shallow–medium oil fields of the Bohai Sea and shallow oil fields of the Pearl River Mouth Basin have potential for CCUS-EOR geological sequestration.LI Yaohua WANG Yang SHI Yu YANG Leilei CUI Qiliang BI Caiqin XU Yinbo WANG Qianyou SHAN Yansheng LIU Weibin MIAO Miao WANG Ting 2023Acta Geologica Sinica(English Edition)2023,97,3:0
9Assessment and Optimization Strategies of Campus Sound Environment显示文摘A good sound environment is essential in creating a harmonious and peaceful campus,improving students’learning outcomes,promoting physical and mental health,and creating a green and healthy campus.This study investigated the impact of new buildings on existing ones by optimizing the spacing between new buildings and the sound insulation structure of building enclosures.The results indicated that building 4 was affected by the noise from new building 1 and its surroundings,with a maximum outdoor daytime noise level reaching 69 dB,and the indoor background noise level in the least favorable classroom was 43.73 dB,less than 45 dB,which was within the acceptable range.It is recommended that the sound insulation design be improved in the planning of new teaching buildings.Besides,the surrounding traffic conditions should be improved,and the usage time of sports facilities should be scheduled appropriately to prevent the noise from sporting activities from affecting the classroom activities.The findings of this study provide valuable references for future architectural acoustics design and campus planning,contributing to the creation of peaceful and comfortable campus environments.Cuicui Qin Qiliang Yu Wei Zhang 2023Journal of World Architecture2023,7,6:0
10Analysis of the Architectural Design Talent Development Direction by Investigating the Employment Status of Architectural Design Graduates显示文摘Based on a comprehensive investigation of the employment status of architectural design graduates at a certain university,this paper analyzes the correctness of the talent development direction of architectural design in hopes of pro-viding a valuable reference for further teaching reform and strengthening school-enterprise collaboration.The research re-sults show that architectural design is the main choice of graduates,accounting for as high as 63%,and traditional architec-tural design skills continue to be in demand in the market.Employment in fields such as interior design,BIM design,and green architecture is also included.The distribution of job positions for graduates is mainly in the areas of scheme design assistants and construction drawing design,requiring software operation,communication,scheme design,and construction drawing skills.This paper also proposes talent development measures such as optimizing the curriculum,strengthening faculty construction,and deepening school-enterprise collaboration,in order to improve the quality of talent development and the competitiveness of graduates.Cuicui Qin Lijuan Xie Qiliang Yu Guanhong Chen Binquan Zhang Yani Gao 2023Journal of Architectural Research and Development2023,7,6:0
11Simulation Evaluation of Outdoor Noise Environment in Buildings显示文摘Green campus design has become an essential strategy to enhance campus life and learning.However,noise pol-lution remains a troubling aspect that impacts teaching and learning processes,even causing harm to the health of students and teachers.Therefore,acoustic environment quality design is crucial.This article focuses on the expansion project of a school campus in Shenzhen.We simulated and analyzed the outdoor noise environment separately for the proposed teach-ing building,as well as the existing buildings like the dining hall,teaching building,and laboratory building.The results showed that the proposed teaching building was mainly affected by surrounding noise,with the worst outdoor noise being in classrooms adjacent to the teaching building in the south and the basketball court at the west of the classroom,with maximum noise values reaching 73 dB and 66 dB,respectively.In the future,these rooms should be renovated to achieve an excellent indoor soundproof environment.Cuicui Qin Qiliang Yu Wenyu Zou 2023Journal of Architectural Research and Development2023,7,6:0
12Tribological mechanism of carbon group nanofluids on grinding interface under minimum quantity lubrication based on molecular dynamic simulation显示文摘Carbon group nanofluids can further improve the friction-reducing and anti-wear properties of minimum quantity lubrication(MQL).However,the formation mechanism of lubrication films generated by carbon group nanofluids on MQL grinding interfaces is not fully revealed due to lack of sufficient evidence.Here,molecular dynamic simulations for the abrasive grain/workpiece interface were conducted under nanofluid MQL,MQL,and dry grinding conditions.Three kinds of carbon group nanoparticles,i.e.,nanodiamond(ND),carbon nanotube(CNT),and graphene nanosheet(GN),were taken as representative specimens.The[BMIM]BF4 ionic liquid was used as base fluid.The materials used as workpiece and abrasive grain were the single-crystal Ni–Fe–Cr series of Ni-based alloy and single-crystal cubic boron nitride(CBN),respectively.Tangential grinding force was used to evaluate the lubrication performance under the grinding conditions.The abrasive grain/workpiece contact states under the different grinding conditions were compared to reveal the formation mechanism of the lubrication film.Investigations showed the formation of a boundary lubrication film on the abrasive grain/workpiece interface under the MQL condition,with the ionic liquid molecules absorbing in the groove-like fractures on the grain wear’s flat face.The boundary lubrication film underwent a friction-reducing effect by reducing the abrasive grain/workpiece contact area.Under the nanofluid MQL condition,the carbon group nanoparticles further enhanced the tribological performance of the MQL technique that had benefited from their corresponding tribological behaviors on the abrasive grain/workpiece interface.The behaviors involved the rolling effect of ND,the rolling and sliding effects of CNT,and the interlayer shear effect of GN.Compared with the findings under the MQL condition,the tangential grinding forces could be further reduced by 8.5%,12.0%,and 14.1%under the diamond,CNT,and graphene nanofluid MQL conditions,respectively.Dexiang WANG Yu ZHANG Qiliang ZHAO Jingliang JIANG Guoliang LIU Changhe LI 2023Frontiers of Mechanical Engineering2023,18,1:0
