| 1 | Development and molecular analysis of a novel acetohydroxyacid synthase rapeseed mutant with high resistance to sulfonylurea herbicides显示文摘With the increasing promotion of simplified rapeseed cultivation in recent years,the development of cultivars with high resistance to herbicides is urgently needed.We previously developed M342,which shows sulfonylurea herbicide resistance,by targeting acetohydroxyacid synthase(AHAS),a key enzyme in branched-chain amino acid synthesis.In the present study,we used a progeny line derived from M342 for an additional round of ethyl methane sulfonate mutagenesis,yielding the novel mutant DS3,which harbored two mutations in AHAS genes and showed high sulfonylurea resistance.One mutation was the substitution Trp574 Leu,as in M342,according to Arabidopsis protein sequencing.The other site was a newly recognized substitution,Pro197 Leu.A KASP marker targeting Pro197 Leu was developed and reliably predicted the response to sulfonylurea herbicides in the F2 population.The combination of Trp574 Leu and Pro197 Leu in DS3 produced a synergistic effect that greatly increased herbicide resistance.Analysis of the protein structures of AHAS1 and AHAS3 in wild-type and single-gene mutant plants revealed three-dimensional protein conformational changes that could account for differences in herbicide resistance characteristics including toxicity tolerance,AHAS enzyme activity,and AHAS gene expression. | Yue Guo Changle Liu Weihua Long Jianqin Gao Jiefu Zhang Song Chen Huiming Pu Maolong Hu | 2022 | The Crop Journal2022，10，1： | 3 |

| 5 | Prediction of Mechanical Properties of Structural Bamboo and Its Relationship with Growth Parameters显示文摘Bamboo is a renewable natural building material with good mechanical properties.However,due to the heterogeneity and anisotropy of bamboo stalk,a large amount of material performance testing costs are required in engineering applications.In this work,longitudinal compression,bending,longitudinal shear,longitudinal tensile,transverse compression and transverse tensile tests of bamboo materials are conducted,considering the influence of the bamboo nodes.The mechanical properties of the whole bamboo stalk with the wall thickness and outer circumference are explored.Through univariate and multiple regression analysis,the relationship between mechanical properties and wall thickness and perimeter is fitted,and the conversion parameters between different mechanical properties are derived.The research results show that the transverse compressive strength of nodal specimen,and transverse tensile strength of nodal and inter-node specimens increase with the increase of wall thickness and outer circumference,but other mechanical properties decrease with the increase of wall thickness and outer circumference.The prediction formula and conversion parameters of bamboo mechanical properties proposed in this research have high applicability and accuracy.Moreover,this research can provide references for the evaluation of bamboo performance and saving test costs. | Pengcheng Liu Ping Xiang Qishi Zhou Hai Zhang Jiefu Tian Misganu Demis Argaw | 2021 | Journal of Renewable Materials2021，9，12： | 1 |

| 10 | Indoor Propagation of Transgenic Glyphosate-tolerant Rapeseed (Brassica napus L.) and Transfer Breeding for Herbicide Tolerance显示文摘[Objectives] This study was conducted to investigate the possibility of screening for herbicide resistance in the early stage of rapes growth. [Methods] Eight treatments were set for a herbicide concentration experiment. [Results] Rape sprouts were highly sensitive to the herbicide glyphosate, and even a very low concentration of glyphosate solution(187 mg/L) was sufficient to kill most of the rape seedlings, while the genetically modified herbicide-tolerant rape could tolerate higher concentrations of the herbicide. Low concentrations of glyphosate could be used for screening at the sprout stage, and the results of herbicide-tolerance screening were consistent with PCR testing. [Conclusions] This study lays a technical and material foundation for accelerating the cultivation of new herbicide-resistant rape varieties suitable for rapeseed production areas in the lower reaches of the Yangtze River. | Xiaoying ZHOU Yaoyao WU Qi PENG Sanxiong FU Wei ZHANG Hongli ZHU Jiefu ZHANG Song CHEN | 2021 | Agricultural Biotechnology2021，10，1： | 0 |
| 11 | Classification and Prediction of Skyrmion Material Based on Machine Learning显示文摘The discovery and study of skyrmion materials play an important role in basic frontier physics research and future information technology.The database of 196 materials,including 64 skyrmions,was established and predicted based on machine learning.A variety of intrinsic features are classified to optimize the model,and more than a dozen methods had been used to estimate the existence of skyrmion in magnetic materials,such as support vector machines,k-nearest neighbor,and ensembles of trees.It is found that magnetic materials can be more accurately divided into skyrmion and non-skyrmion classes by using the classification of electronic layer.Note that the rare earths are the key elements affecting the production of skyrmion.The accuracy and reliability of random undersampling bagged trees were 87.5%and 0.89,respectively,which have the potential to build a reliable machine learning model from small data.The existence of skyrmions in LaBaMnO is predicted by the trained model and verified by micromagnetic theory and experiments. | Dan Liu Zhixin Liu JinE Zhang Yinong Yin Jianfeng Xi Lichen Wang JieFu Xiong Ming Zhang Tongyun Zhao Jiaying Jin Fengxia Hu Jirong Sun Jun Shen Baogen Shen | 2023 | Research2023，，4： | 0 |

| 13 | Tunable In-Plane Anisotropy in Amorphous Sm Co Films Grown on(011)-Oriented Single-Crystal Substrates显示文摘Amorphous Sm-Co films with uniaxial in-plane anisotropy have great potential for application in information-storage media and spintronic materials.The most effective method to produce uniaxial inplane anisotropy is to apply an in-plane magnetic field during deposition.However,this method inevitably requires more complex equipment.Here,we report a new way to produce uniaxial in-plane anisotropy by growing amorphous Sm-Co films onto(011)-cut single-crystal substrates in the absence of an external magnetic field.The tunable anisotropy constant,kA,is demonstrated with variation in the lattice parameter of the substrates.A kA value as high as about 3.3×10^4J·m^-3 was obtained in the amorphous Sm-Co film grown on a LaAlO3(011)substrate.Detailed analysis indicated that the preferential seeding and growth of ferromagnetic(FM)domains caused by the anisotropic strain of the substrates,along with the formed Sm-Co,Co-Co directional pair ordering,exert a substantial effect.This work provides a new way to obtain in-plane anisotropy in amorphous Sm-Co films. | Wenhui Liang Houbo Zhou Jiefu Xiong Fengxia Hu Jia Li Jian Zhang Jing Wang Jirong Sun Baogen Shen | 2020 | Engineering2020，6，2： | 0 |
| 14 | Flight control of a flying wing aircraft based on circulation control using synthetic jet actuators显示文摘To achieve the nice stealth performance and aerodynamic maneuverability of a Flying Wing Aircraft(FWA),a longitudinal aerodynamic control technology based on circulation control using trailing-edge synthetic jet actuators was proposed without the movement of rudders.Effects on the longitudinal aerodynamic characteristics of a small-sweep FWA were investigated.Then,flight tests were carried out to verify the control abilities,providing a novel technology for the design of a future rudderless FWA.Results show that synthetic jets could narrow the dead zone area,improve the flow velocity near the trailing edge,and then move the trailing-edge separation point and the leading-edge stagnation point downwards,which make the effective Attack of Angle(AOA)increase,thereby enhancing the pressure envelope area.Circulation control based on synthetic jets could improve the lift,drag and nose-down moment.The variations of lift and nosedown moment decrease with the growth of AOA caused by the improved reverse pressure gradient and the weakened circulation control efficiency.Finally,synthetic jet actuators were integrated into the trailing edge of a small-sweep FWA,which could realize the roll and pitch control without deflections of rudders during the cruise stage,and the maximum roll and pitch angular velocity are 12.64(°)/s and 8.51(°)/s,respectively. | Zhijie ZHAO Xiong DENG Zhenbing LUO Wenqiang PENG Jianyuan ZHANG Jiefu LIU | 2023 | Chinese Journal of Aeronautics2023，36，10： | 0 |
| 15 | Novel yaw effector of a flying wing aircraft based on reverse dual synthetic jets显示文摘For achieving the nice stealth performance and aerodynamic maneuverability of a Flying Wing Aircraft(FWA),a novel yaw effector based on Reverse Dual Synthetic Jets(RDSJ)was proposed without the movement of rudders.Effects on aerodynamic characteristics of a small-sweep FWA and control mechanism were investigated by numerical simulations.Finally,reverse dual synthetic jet actuators were integrated into a real FWA and flight tests were firstly carried out.Numerical results show that RDSJ could make drag coefficient increase and weaken lift coefficient,which generate a yawing moment and a rolling moment in the same direction,realizing control of heading attitudes,but strong coupling with the pitching moment occurs at large angles of attack.For control mechanism,RDSJ could produce two reverse synthetic jets out of phases,improve the reverse pressure gradient and hence form alternate recirculation zones or even early large-area separation,which cause the rise of pressures before exits and the dip of pressures behind exits,achieving improvement of drag and the yawing moment.The results of flight tests support that RDSJ could realize control of heading attitudes without deflections of rudders during the cruise stage and achieve the maximal yaw angular velocity of 10.12(°)/s,verifying the feasibility of this novel yaw effector. | Zhijie ZHAO Zhenbing LUO Xiong DENG Jianyuan ZHANG Zhaofeng DONG Jiefu LIU Shiqing LI | 2023 | Chinese Journal of Aeronautics2023，36，12： | 0 |
| 16 | Learning the Mapping x→Σi=1^d xi^(2):the Cost of Finding the Needle in a Haystack显示文摘The task of using the machine learning to approximate the mapping x→Σi=1^d xi^(2)with Xi∈[-1,1]seems to be a trivial one.Given the knowledge of the separable structure of the function,one can design a sparse network to represent the function very accurately,or even exactly.When such structural information is not available,and we may only use a dense neural network,the optimization procedure to find the sparse network embedded in the dense network is similar to finding the needle in a haystack,using a given number of samples of the function.We demonstrate that the cost(measured by sample complexity)of finding the needle is directly related to the Barron norm of the function.While only a small number of samples are needed to train a sparse network,the dense network trained with the same number of samples exhibits large test loss and a large generalization gap.To control the size of the generalization gap,we find that the use of the explicit regularization becomes increasingly more important as d increases.The numerically observed sample complexity with explicit regularization scales as G(d^(2.5)),which is in fact better than the theoretically predicted sample complexity that scales as 0(d^(4)).Without the explicit regularization(also called the implicit regularization),the numerically observed sample complexity is significantly higher and is close to 0(d^(4.5)). | Jiefu Zhang Leonardo Zepeda-Nunez Yuan Yao Lin Lin | 2021 | Communications on Applied Mathematics and Computation2021，3，2： | 0 |
