1The design and construction of a pulsed beam generation system based on high intensity cyclotron显示文摘In order to perform the studies on a pulsed beam generation system based on a high intensity cyclotron, a test beam line with a pulsed beam generation for a 10 MeV compact cyclotron (CYCIAE-10) has been designed and constructed at China Institute of Atomic Energy (CIAE). A 70 MHz continuous H- beam can be pulsed to the pulse length of less than 10 ns with a repetition rate of 4.4 MHz. The sine waveform with a frequency of 2.2 MHz is adopted for the chopper and a mesh structure with single drift and dual gaps is used for the 70 MHz buncher. A helical resonator is designed and constructed based on simulations and experiments on the RF matching for the chopper. A helical inductance loop that is exceptionally large of its kind and equipped with water cooling for the resonator has been successfully wound and a 500 W solid RF amplifier has been manufactured. A special measuring device has been designed, which can be used to measure both the DC beam and the pulsed beam. The required pulsed beam was obtained after pulsed beam tuning.AN ShiZhong YIN ZhiGuo LI PengZhan SONG GuoFang WU LongCheng GUAN FengPing XIE HuaiDong JIA XianLu LU YinLong ZHANG TianJue 2011Science China(Physics,Mechanics & Astronomy)2011,54,S2:3
2Comprehensive test stand for high-intensity cyclotron development显示文摘A comprehensive test stand for high-intensity cyclotron development,a 10 MeV 430 μA cyclotron,has been successfully constructed at China Institute of Atomic Energy (CIAE) for the experimental verification of the viability of a 100 MeV high-intensity cyclotron (CYCIAE-100) being constructed at CIAE.The verification includes the overall design technology,detail design and engineering technology for the crucial parts of the machine,e.g.main magnet and beam diagnostics.It will also pave the way for future enhancement of the beam intensity.The test stand consists of a H-ion source,axial injection system,central region,main magnet and coil,RF resonator,stripping extraction,and auxiliary systems,which include the RF power amplifier,high voltage and DC power supplies,electric apparatus,beam diagnostics,control,vacuum,water cooling,pneumatic system,and safety interlock.This paper presents the work regarding the design and sub-system development of the test sand,and the results of the beam commissioning of the machine.ZHANG TianJue LI ZhenGuo CHU ChengJie XING JianSheng GUAN FengPing ZHONG JunQing JI Bin GE Tao YIN ZhiGuo HOU ShiGang PAN GaoFeng YAO HongJuan LU YinLong WANG ZhenHui WU LongCheng LIN Jun JIA XianLu WEI SuMin WEN LiPeng WANG Feng XIA Le CAI HongRu XIE HuaiDong CHEN RongFan ZHANG Yan ZHANG SuPing LIU GengShou ZOU Jian AN ShiZhong YANG JianJun BI YuanJie YANG Fang 2011Chinese Science Bulletin2011,56,3:3

4XRCC1 Arg399Gln and Arg194Trp polymorphisms regulate XRCC1 expression and chemoresistance of non-small cell lung cancer cells显示文摘X-ray repair cross-complementing protein 1(XRCC1)could repair cisplatin-induced DNA damage.XRCC1 Arg399Gln and Arg194Trp variants alter XRCC1 expression and function,leading to changes in cancer sensitivity to cisplatin treatment.This study aimed to investigate the effects of XRCC1 Arg399Gln and Arg194Trp polymorphisms on cell viability,apoptosis and XRCC1 expression in cisplatin-sensitive A549 and cisplatin-resistant A549/DDP non-small cell lung cancer(NSCLC)cells.Plasmids carrying XRCC1 Arg399Gln and Arg194Trp were constructed and transfected into A549 and A549/DDP cells.RT-PCR,Western blot,MTT assay,and flow cytometry analysis were performed to assess cell viability,apoptosis,and XRCC1 expression.Compared to control cells,the viability of A549 and A549/DDP cells transfected with XRCC1 Arg399Gln and Arg194Trp was higher and the apoptosis rate was lower,and XRCC1 mRNA and protein expression levels were significantly higher.In conclusion,our results suggest that XRCC1 Arg399Gln and Arg194Trp polymorphisms change XRCC1 expression in NSCLC cells and alter the sensitivity of NSCLC to cisplatin-based chemotherapy.DAIRONG LI XIANLU ZHUO LUMI HUANG XIAOHUI JI DONGLIN WANG 2019BIOCELL2019,43,3:1
5Simulation and experiment of a transplanting mechanism for sweet potato seedlings with ‘boat-bottom’ transplanting trajectory显示文摘Planting on mulched soil is the main cultivation mode for sweet potato slips in spring in northern China.The‘boatbottom’planting method can bring high quantity and similar size for sweet potatoes.In this study,a mechanism for transplanting sweet potato seedlings on mulched was proposed,which could realize‘boat-bottom’transplanting trajectory and improve the planting efficiency.The virtual prototype model of the transplanting mechanism was constructed using ADAMS software,a soil particle model and a flexible body model of sweet potato seedling were established using EDEM software,and then a joint simulation was carried out to find out the interaction of mechanism,seedling and soil.By simulation,the trajectory of the clamping point,the sweet potato seedling posture,soil particles,pits,and relative force were all analyzed,which verified the rationality of the transplanting mechanism design.Finally,three kinds of sweet potato seedlings,watermelon red,Yan-25,and purple sweet potato seedlings were selected,and transplanting experiments were carried out on the mulch to verify that the theoretical trajectory,the simulated trajectory,and the actual trajectory were consistent.The transplanting success rates of the three kinds of sweet potato seedlings were all above 85%,indicating that different varieties of sweet potato seedlings had little effect on the transplanting effect of the mechanism,which reflected that the transplanting mechanism had good practicability and adaptability.Yuanyuan Shao Hongdong Zhang Guantao Xuan Tao Zhang Xianlu Guan Fuhui Wang 2023International Journal of Agricultural and Biological Engineering2023,16,3:1

11A multi-step attack-correlation method with privacy protection显示文摘In the era of global Internet security threats,there is an urgent need for different organizations to cooperate and jointly fight against cyber attacks.We present an algorithm that combines a privacy-preserving technique and a multi-step attack-correlation method to better balance the privacy and availability of alarm data.This algorithm is used to construct multi-step attack scenarios by discovering sequential attack-behavior patterns.It analyzes the time-sequential characteristics of attack behaviors and implements a support-evaluation method.Optimized candidate attack-sequence generation is applied to solve the problem of pre-defined association-rule complexity,as well as expert-knowledge dependency.An enhanced k-anonymity method is applied to this algorithm to preserve privacy.Experimental results indicate that the algorithm has better performance and accuracy for multi-step attack correlation than other methods,and reaches a good balance between efficiency and privacy.ZHANG Yongtang LUO Xianlu LUO Haibo 2016Journal of Communications and Information Networks2016,1,4:1

14Controllable growth of single-crystalline zinc oxide nanosheets under ambient condition toward ammonia sensing with ultrahigh selectivity and sensitivity显示文摘To date,the synthesis of crystalline ZnO nanostructures was often performed under high temperatures and/or high pressures with tiny output,which limits their commercial applications.Herein,we report the progress on synthesizing single-crystalline ZnO nanosheets under ambient conditions(i.e.,room temperature(RT)and atmospheric pressure)based on a sonochemistry strategy.Furthermore,their controllable growth is accomplished by adjusting the pH values of solutions,enabling the tailored crystal growth habits on the polar-charged faces of ZnO along c-axis.As a proof of concept for their potential applications,the ZnO nanosheets exhibit highly efficient performance for sensing ammonia at RT,with ultrahigh sensitivity(S=610 at 100 ppm),excellent selectivity,rapid detection(response time/recover time=70 s/4 s),and outstanding detection limit down to 0.5 ppm,superior to those of all pure ZnO nanostructures and most ZnO-based composite counterparts ever reported.The present work might open a door for controllable production of ZnO nanostructures under mild conditions,and facilitate the exploration of modern gas sensors for detecting gaseous molecules at RT,which underscores their potential toward practical applications in opto-electronic nanodevices.Dongdong ZHANG Zhi FANG Lin WANG Hao YU Xianlu LU Kai SONG Jie TENG Weiyou YANG 2022Journal of Advanced Ceramics2022,11,8:1

17Gold-nanoparticle-based multiplex immuno-strip biosensor for simultaneous determination of 83 antibiotics显示文摘Antibiotic residues,generated by the irrational use of drugs and environmental pollution,have always been a great challenge to aquaculture safety.Therefore,a quick,convenient,and performance-excellent way to detect antibiotic residues in aquaculture fish is urgently required.In this study,a multiplex immunochromatographic strip biosensor based on gold nanoparticles was developed for the simultaneous detection of five classes of antibiotic residues(24β-lactam antibiotics,26 sulfonamides,five tetracyclines,24 quinolones,and four amphenicols)in aquaculture fish within 10 min.The detection ranges of five representative antibiotics,penicillin G,sulfamethazine,tetracycline,enrofloxacin,and chloramphenicol,were 2.33–38.4,0.688–17.1,1.4–48.1,1.45–32.9,and 0.537–9.06μg/kg,respectively.The accuracy and stability of these measurements were demonstrated by analyzing spiked fish samples,with recovery rates of 87.5%–115.2%and a coefficient of variation<9.5%.The cross-reaction rates,based on the five representative antibiotics,were 3.77%–202%forβ-lactams,3.95%–137%for sulfonamides,9.19%–100%for tetracyclines,4.9%–145%for quinolones,and 3.2%–100%for amphenicols.The excellent testing performance of the biosensor strip to most of antibiotic residues in aquaculture fish ensures they meet the maximum residue limits required by countries or organizations.Therefore,this multiplex immunochromatographic strip biosensor is potentially applicable to the rapidly on-site determination of antibiotic residues in aquaculture fish.Xianlu Lei Xinxin Xu Liqiang Liu Liguang Xu Li Wang Hua Kuang Chuanlai Xu 2023Nano Research2023,16,1:0
18Dinitrogen Functionalization Affording Structurally Well-Defined Cobalt Diazenido Complexes显示文摘Cobalt-bis(dinitrogen)complexes[LCo(N_(2))_(2)]−(3,4)with simple and commercially available bidentate phosphine ligands(L:Cy_(2)PCH_(2)CH_(2)PCy_(2))were synthesized and structurally characterized.Further N2 functionalization by treating the complex 3b with i Pr_(3)SiCl afforded the first structurally characterized cobalt diazenido complex 5.These complexes 3–5 were found to be effective catalysts for the transformation of N2 into N(SiMe_(3))_(3).The electronic structure of the cobalt diazenido complex 5 is supported by quantum computational calculations based on stateof-the-art energy decomposition analysis(EDA)in conjunction with the natural orbitals for chemical valence(NOCV)method.Mingdong Zhong Xianlu Cui Botao Wu Gao-Xiang Wang Wen-Xiong Zhang Junnian Wei Lili Zhao Zhenfeng Xi 2022CCS Chemistry2022,4,2:0
19Effect of heating and cooling technology on microstructure of galvannealed coating显示文摘Based on the galvannealed phase transformation theory,the phase and powder level of a galvannealed coating produced on one of the galvanizing lines at Baosteel*s cold-rolling plant were analyzed under different conditions before and after a technical innovation was introduced.After the introduction of the technical innovation,heating and cooling abilities of the galvannealing furnace were strengthened,galvanizing speed increased from 75 to 100 m/min,and the galvannealing target temperature could be reached more quickly.As such,the 8,phase was more uniform and dense,and the coating's anti-powdering ability was increased.Although the galvanizing time was slightly shortened,this had no negative effect on the anti-powdering ability of the galvannealed coating.MENG Xianlu QIAN Hongwei 2020Baosteel Technical Research2020,14,1:0
