| 1 | Field evaluation of effects of transgenic cry1Ab/cry1Ac,cry1C and cry2A rice on Cnaphalocrocis medinalis and its arthropod predators显示文摘The impacts of transgenic Bt rice on target pests and their predators need to be clarified prior to the commercialization of Bt rice.In this study,the percentages of folded leaves of three transgenic Bt rice lines and non-transgenic parental rice line caused by Cnaphalocrocis medinalis were studied over two successive growing seasons.In addition,the population densities,relative abundance and population dynamics of C.medinalis and four species of its natural arthropod predators were investigated at three sites in China.The results showed that rice line significantly affected the percentages of folded leaves and population densities of C.medinalis larvae.Significantly higher percentages of folded leaves were observed on the non-transgenic rice compared with the three transgenic Bt rice on most sampling dates.Significantly higher densities of C.medinalis larvae and higher relative abundance of C.medinalis within phytophages were found on non-transgenic rice compared with three transgenic Bt rice at different sites across the study period.The population dynamics of C.medinalis larvae were significantly affected by rice line,rice line×sampling date,rice line×year,rice line×sampling date×year.However,there was little,if any,significant difference in the relative abundance,population density and population dynamics of the four arthropod predators between the three Bt rice lines and non-transgenic rice.The results of this study indicate that the Bt toxin in transgenic Bt rice can effectively suppress the occurrence of C.medinalis,but has no significant effects on the occurrence of the four predatory arthropod species. | XU XueLiang HAN Yu WU Gang CAI WanLun YUAN BenQi WANG Hui LIU FangZhou WANG ManQun HUA HongXia | 2011 | Science China(Life Sciences)2011，54，11： | 14 |
| 2 | Towards automatic freeform optics design: coarse and fine search of the three-mirror solution space显示文摘Design of an optical system,whether classic or novel,in the past or the present,requires significant effort from the designer.In addition to design methods and theories,the designer’s skills and experience in optical system design are particularly important,which may require years of practice to learn.The diversity and variety of results are limited because of the difficulty,time,and labor costs required.In this article,we propose an automatic design method for freeform optics that can achieve a diverse range of three-mirror designs.The optical specifications and the design constraints are the only inputs required,and a variety of results can be obtained automatically.The output results have various structures and various optical power distributions with high imaging qualities.By implementing the design method,designers can not only realize an overview of the solution space of the three-mirror freeform system,but can also focus on specific designs. | Benqi Zhang Guofan Jin Jun Zhu | 2021 | Light(Science & Applications)2021，10，4： | 2 |

| 5 | The relationship between slip behavior and dislocation arrangement for large-size Mo-3Nb single crystal at room temperature显示文摘The slip behavior and mechanism of large-size Mo-3Nb single crystal have been investigated and disclosed comprehensively at room temperature by quasi-static compression with various strains.With the increase of deformation,the slip traces change from shallow non-uniform slip lines to dense and uniform slip bands.Different slip traces in the same deformation condition were observed,suggesting that the slip traces in the single crystal are controlled by different types and arrangement mechanisms of mobile dislocation.To clarify the relationship between slip behavior and dislocation arrangement,TEM and AFM analyses were performed.Significant discrepancy between the mobility of screw segments and edge segments caused by double cross-slip multiplication mechanism is the reason why different slip features were witnessed.During the whole slip deformation process,screw dislocations play a dominant role and they are inclined to form wall-substructures by interaction and entanglement.With the development of dislocation accumulation,the entangled dislocation walls evolve into dislocation cells with higher stability. | Benqi Jiao Qinyang Zhao Yongqing Zhao Laiping Li Zhongwu Hu Xuanqiao Gao Wen Zhang Jianfeng Li | 2021 | Journal of Materials Science & Technology2021，，33： | 1 |

| 8 | An hp Adaptive Uniaxial Perfectly Matched Layer Method for Helmholtz Scattering Problems显示文摘We propose an adaptive strategy for solving high frequency Helmholtz scattering problems.The method is based on the uniaxial PML method to truncate the scattering problem which is defined in the unbounded domain into the bounded domain.The parameters in the uniaxial PML method are determined by sharp a posteriori error estimates developed by Chen and Wu[8].An hp-adaptive finite element strategy is proposed to solve the uniaxial PML equation.Numerical experiments are included which indicate the desirable exponential decay property of the error. | Zhiming Chen Benqi Guo Yuanming Xiao | 2009 | Communications in Computational Physics2009，5，2： | 1 |
| 9 | An h-p Petrov-Galerkin finite element method for linear Volterra integro-differential equations显示文摘We analyze an h-p version Petrov-Galerkin finite element method for linear Volterra integrodifferential equations. We prove optimal a priori error bounds in the L2- and H1-norm that are explicit in the time steps,the approximation orders and in the regularity of the exact solution. Numerical experiments confirm the theoretical results. Moreover,we observe that the numerical scheme superconverges at the nodal points of the time partition. | YI LiJun GUO BenQi | 2014 | Science China Mathematics2014，57，11： | 1 |

| 12 | Improved sparse representation based on local preserving projection for the fault diagnosis of multivariable system显示文摘Dear editor,To satisfy the increasing requirements for safety and quality in industrial processes,process monitoring has been actively investigated in the past decade.The most critical aspects of this approach are the detection of faults in realtime and the diagnosis of fault types.Redundancy and coupling among these variables make it difficult to identify existing correlations between faults and variables,which hinders the quick detection of faults.Furthermore,the large amount of available monitoring data often obscures information about abnormalities and faults.Effective dimension reduction and feature extraction are imperative to address this challenge[1,2]. | Qiu TANG Benqi LI Yi CHAI Jianfeng QU Hao REN | 2021 | Science China(Information Sciences)2021，64，2： | 0 |
| 13 | A-Posteriori Error Estimation for the Legendre Spectral Galerkin Method in One-Dimension显示文摘In this paper,a-posteriori error estimators are proposed for the Legendre spectral Galerkin method for two-point boundary value problems.The key idea is to postprocess the Galerkin approximation,and the analysis shows that the postprocess improves the order of convergence.Consequently,we obtain asymptotically exact aposteriori error estimators based on the postprocessing results.Numerical examples are included to illustrate the theoretical analysis. | Lijun Yi Benqi Guo | 2010 | Numerical Mathematics(Theory,Methods and Applications)2010，3，1： | 0 |
