| 1 | The mortality of lung cancer attributable to smoking among adults in China and the United States during 1990–2017显示文摘Background:Statistical data on the burden and relevant risk factors of lung cancer are valuable for policy-making.This study aimed to compare the mortality of lung cancer attributable to smoking stratified by sex and age among adults in China and the United States(US).Methods:We extracted age-standardized mortality rates of lung cancer during 1990-2017 using the comparative risk assessment framework of the 2017 Global Burden of Disease study.We performed an age-period-cohort analysis to estimate time trend of lung cancer mortality attributable to smoking.Results:During 1990-2017,the age-standardized mortality rate of lung cancer was increasing in China but decreasing in the US for both sexes.The mortality attributable to smoking in China showed a generally increasing trend,while a continuous decrease was observed in the US.The age-period-cohort analysis showed a similar trend of age effect among adults between China and the US:the mortality substantially increased from the 30-34 to 80-84 age group and subsequently decreased in the 90-94 age group.However,the period effect rapidly increased in Chinese adults during 1990-2017,while it tended to be stable in the US although it was still slightly increasing in women.The cohort effect generally peaked in the earlier cohort born in 1902-1906 in the two countries.Conclusions:During 1990-2017,the lung cancer mortality attributable to smoking and the period effect are generally increasing in Chinese adults;the mortality attributable to smoking is decreasing in the US adults,but the period effect tends to be stable.The rapid aging and prevalence of smoking may intensify the increasing mortality of lung cancer in China. | Xiaoxue Liu Yong Yu Minsheng Wang Sumaira Mubarik Fang Wang Yafeng Wang Runtang Meng Chuanhua Yu | 2020 | Cancer Communications2020，40，11： | 17 |
| 2 | High-resolution 3D crustal S-wave velocity structure of the MiddleLower Yangtze River Metallogenic Belt and implications for its deep geodynamic setting显示文摘The Middle-Lower Yangtze River Metallogenic Belt(MLYMB) is an important mineral resource region in China.High-resolution crustal models can provide crucial constraints to understand the ore-forming processes and geodynamic setting in this region. Using ambient seismic noise from 107 permanent and 82 portable stations in the MLYMB and the adjacent area,we present a new high-resolution 3D S-wave velocity model of this region. We first extract 5–50 s Rayleigh wave phase velocity dispersion data by calculating ambient noise cross-correlation functions(CFs) and then use the surface wave direct inversion method to invert the mixed path travel times for the 3D S-wave velocity structure. Checkerboard tests show that the horizontal resolution of the 3D S-wave velocity model is approximately 0.5°–1.0° and that the vertical resolution decreases with increasing noise and depth. Our high-resolution 3D S-wave velocity model reveals:(1) AV-shaped high-velocity zone(HVZ) is located in the lower crust and the uppermost mantle in the study region. The western branch of the HVZ passes through the Jianghan Basin,the Qinling-Dabie orogenic belt and the Nanxiang Basin. The eastern branch, which almost completely covers the main body of the MLYMB, is located near the Tanlu Fault. The low-velocity anomalies between the western and eastern branches are located in the area of the Qinling-Dabie orogenic belt.(2) High-velocity uplifts(HVUs) are common in the crust of the MLYMB,especially in the areas near the Tanlu Fault, the Changjiang Fault and the Yangxin-Changzhou Fault. The intensities of the HVUs gradually weaken from west to east. The V-shaped HVZ in the lower crust and uppermost mantle and the HVUs in the middle and lower crust likely represent cooled mantle intrusive rocks. During the Yanshanian period, fault systems formed in the MLYMB due to the convergence between the South China Plate and the North China Plate, the multiple-direction drifting of the PaleoPacific Plate and its subduction beneath the Eurasian Plate. The dehydration of the cold oceanic crust led to partial melting in the upper mantle. Temperature differences caused strong convection of the upper mantle material that underplated the lower crust and rose to near the surface along the deep fault systems. After mixing with the crustal materials, mineralization processes, such as assimilation and fractional crystallization, occurred in the MLYMB. | Song LUO Huajian YAO Qiusheng LI Weitao WANG Kesong WAN Yafeng MENG Bin LIU | 2019 | Science China Earth Sciences2019，62，9： | 13 |
| 3 | Fault self-repair strategy based on evolvable hardware and reparation balance technology显示文摘In the face of harsh natural environment applications such as earth-orbiting and deep space satellites, underwater sea vehicles, strong electromagnetic interference and temperature stress,the circuits faults appear easily. Circuit faults will inevitably lead to serious losses of availability or impeded mission success without self-repair over the mission duration. Traditional fault-repair methods based on redundant fault-tolerant technique are straightforward to implement, yet their area, power and weight cost can be excessive. Moreover they utilize all plug-in or component level circuits to realize redundant backup, such that their applicability is limited. Hence, a novel selfrepair technology based on evolvable hardware(EHW) and reparation balance technology(RBT) is proposed. Its cost is low, and fault self-repair of various circuits and devices can be realized through dynamic configuration. Making full use of the fault signals, correcting circuit can be found through EHW technique to realize the balance and compensation of the fault output-signals. In this paper, the self-repair model was analyzed which based on EHW and RBT technique, the specific self-repair strategy was studied, the corresponding self-repair circuit fault system was designed, and the typical faults were simulated and analyzed which combined with the actual electronic devices. Simulation results demonstrated that the proposed fault self-repair strategy was feasible. Compared to traditional techniques, fault self-repair based on EHW consumes fewer hardware resources, and the scope of fault self-repair was expanded significantly. | Zhang Junbin Cai Jinyan Meng Yafeng Meng Tianzhen | 2014 | Chinese Journal of Aeronautics2014，27，5： | 10 |

| 5 | Embryonic array configuration optimization method based on reliability and hardware consumption显示文摘Embryonic Array(EA) with different configuration methods will directly affect its reliability and hardware consumption. At present, EA configuration design is lack of quantitative analysis method. In order to reasonably optimize EA configuration design, an EA configuration optimization design method is proposed, which is based on the constraints of EA hardware consumption and reliability. Through the analysis of EA working process and composition, quantitative analysis of EA reliability and hardware consumption are completed. Based on the constraints of EA hardware consumption and reliability, the mathematical model of EA configuration optimization design is established, which transfers EA configuration optimization design into an integer nonlinear programming model problem. According to the difference of the fitness value of individual waiting for mutation in population, adaptive mutation operator and crossover operator are selected, and a novel Modified Adaptive Differential Evolution(MADE) algorithm is proposed,which is used to solve EA configuration optimization design problem. Simulation experiments and analysis indicate that the MADE is able to effectively improve the speed, accuracy and stability of algorithm. Moreover, the proposed EA configuration optimization design method can select the most reasonable EA configuration design, and play an important guiding role in EA optimization design. | Tao WANG Jinyan CAI Yafeng MENG Sai ZHU | 2019 | Chinese Journal of Aeronautics2019，32，3： | 1 |
| 6 | Optimal Design of Rectification Circuit in Electronic Circuit Fault Self-repair Based on EHW and RBT显示文摘Reliability of traditional electronic circuit is improved mainly by redundant fault-tolerant technology with large hardware resource consumption and limited fault self-repair capability. In complicated environment,electronic circuit faults appear easily. If on-site immediate repair is not implemented, normal running of electronic system will be directly affected. In order to solve these problems, Evolvable hardware(EHW) technology is widely used. The conventional EHW has some bottlenecks.The optimal design of Rectification circuit(RTC) is further researched on the basis of the previously proposed fault self-repair based on EHW and Reparation balance technology(RBT). Fault sets are selected by fault danger degree and fault coverage rate. The optimal designed RTC can completely repair faults in the fault set. Simulation results prove that it has higher self-repair capability and less hardware resource. | ZHANG Junbin CAI Jinyan MENG Yafeng | 2018 | Chinese Journal of Electronics2018，27，1： | 1 |
| 7 | A reliability evaluation method for embryonic cellular array based on Markov status graph model显示文摘Due to the limitations of the existing fault detection methods in the embryonic cellular array(ECA), the fault detection coverage cannot reach 100%. In order to evaluate the reliability of the ECA more accurately, embryonic cell and its input and output(I/O) resources are considered as a whole, named functional unit(FU). The FU fault detection coverage parameter is introduced to ECA reliability analysis, and a new ECA reliability evaluation method based on the Markov status graph model is proposed.Simulation experiment results indicate that the proposed ECA reliability evaluation method can evaluate the ECA reliability more effectively and accurately. Based on the proposed reliability evaluation method, the influence of parameters change on the ECA reliability is studied, and simulation experiment results show that ECA reliability can be improved by increasing the FU fault detection coverage and reducing the FU failure rate. In addition, by increasing the scale of the ECA, the reliability increases to the maximum first, and then it will decrease continuously. ECA reliability variation rules can not only provide theoretical guidance for the ECA optimization design, but also point out the direction for further research. | WANG Tao CAI Jinyan MENG Yafeng ZHU Sai | 2020 | Journal of Systems Engineering and Electronics2020，31，2： | 1 |
| 8 | Optimal design of RTCs in digital circuit fault self-repair based on global signal optimization显示文摘Since digital circuits have been widely and thoroughly applied in various fields, electronic systems are increasingly more complicated and require greater reliability. Faults may occur in electronic systems in complicated environments. If immediate field repairs are not made on the faults, electronic systems will not run normally, and this will lead to serious losses. The traditional method for improving system reliability based on redundant fault-tolerant technique has been unable to meet the requirements. Therefore, on the basis of(evolvable hardware)-based and(reparation balance technology)-based electronic circuit fault self-repair strategy proposed in our preliminary work, the optimal design of rectification circuits(RTCs) in electronic circuit fault self-repair based on global signal optimization is deeply researched in this paper. First of all, the basic theory of RTC optimal design based on global signal optimization is proposed. Secondly, relevant considerations and suitable ranges are analyzed. Then, the basic flow of RTC optimal design is researched. Eventually, a typical circuit is selected for simulation verification, and detailed simulated analysis is made on five circumstances that occur during RTC evolution. The simulation results prove that compared with the conventional design method based RTC, the global signal optimization design method based RTC is lower in hardware cost, faster in circuit evolution, higher in convergent precision, and higher in circuit evolution success rate. Therefore, the global signal optimization based RTC optimal design method applied in the electronic circuit fault self-repair technology is proven to be feasible, effective, and advantageous. | Zhang Junbin Cai Jinyan Meng Yafeng | 2016 | Chinese Journal of Aeronautics2016，29，6： | 0 |
| 9 | Adsorption Site Regulations of[W–O]‑Doped CoP Boosting the Hydrazine Oxidation‑Coupled Hydrogen Evolution at Elevated Current Density显示文摘Hydrazine oxidation reaction(HzOR)assisted hydrogen evolution reaction(HER)offers a feasible path for low power consumption to hydrogen production.Unfortunately however,the total electrooxidation of hydrazine in anode and the dissociation kinetics of water in cathode are critically depend on the interaction between the reaction intermediates and surface of catalysts,which are still challenging due to the totally different catalytic mechanisms.Herein,the[W–O]group with strong adsorption capacity is introduced into CoP nanoflakes to fabricate bifunctional catalyst,which possesses excellent catalytic performances towards both HER(185.60 mV at 1000 mA cm^(−2))and HzOR(78.99 mV at 10,00 mA cm^(−2))with the overall electrolyzer potential of 1.634 V lower than that of the water splitting system at 100 mA cm^(−2).The introduction of[W–O]groups,working as the adsorption sites for H2O dissociation and N2H4 dehydrogenation,leads to the formation of porous structure on CoP nanoflakes and regulates the electronic structure of Co through the linked O in[W–O]group as well,resultantly boosting the hydrogen production and HzOR.Moreover,a proof-of-concept direct hydrazine fuel cell-powered H_(2) production system has been assembled,realizing H_(2)evolution at a rate of 3.53 mmol cm^(−2)h^(−1)at room temperature without external electricity supply. | Ge Meng Ziwei Chang Libo Zhu Chang Chen Yafeng Chen Han Tian Wenshu Luo Wenping Sun Xiangzhi Cui Jianlin Shi | 2023 | Nano-Micro Letters2023，15，11： | 0 |

| 11 | Observer-based State Feedback Control to Suppress Stick-slip Vibrations in Oil Well Drill-string显示文摘In drilling field, stick-slip vibrations of the drill-string are the main reason for the failure of the drilling system. To suppress the undesired stick-slip vibrations, an observer-based state feedback control method is proposed. The drilling system is described by a lumped parameter model including a Karnopp friction torque model. A state observer is designed to estimate the bit velocity in bottom hole and a state feedback controller is proposed to control the top drive velocity. By simulation, the performance of the control algorithm is demonstrated. Based on the control algorithm, a stick-slip vibration control system is developed. Test results show that the control system can effectively eliminate stick-slip vibrations of the drill-string and can be applied to the drilling field. | FU Meng LI Jianghong WU Yafeng WU Ruobin QIU Wenwei | 2019 | International Journal of Plant Engineering and Management2019，24，2： | 0 |
