| 1 | IntegrinαEβ7^(+)T cells direct intestinal stem cell fate decisions via adhesion signaling显示文摘Intestinal stem cell(ISC)differentiation is regulated precisely by a niche in the crypt,where lymphocytes may interact with stem and transient amplifying(TA)cells.However,whether and how lymphocyte–stem/TA cell contact affects ISC differentiation is largely unknown.Here,we uncover a novel role of T cell–stem/TA cell contact in ISC fate decisions.We show that intestinal lymphocyte depletion results in skewed ISC differentiation in mice,which can be rescued by T cell transfer.Mechanistically,integrinαEβ7 expressed on T cells binds to E-cadherin on ISCs and TA cells,triggering E-cadherin endocytosis and the consequent Wnt and Notch signaling alterations.BlockingαEβ7−E-cadherin adhesion suppresses Wnt signaling and promotes Notch signaling in ISCs and TA cells,leading to defective ISC differentiation.Thus,αEβ7^(+)T cells regulate ISC differentiation at single-cell level through cell–cell contact-mediatedαEβ7−E-cadherin adhesion signaling,highlighting a critical role of the T cell–stem/TA cell contact in maintaining intestinal homeostasis. | Shiyang Chen Yajuan Zheng Xiaojuan Ran Hui Du Hua Feng Lei Yang Yating Wen Changdong Lin Shihui Wang Mengwen Huang Zhanjun Yan Dianqing Wu Hongyan Wang Gaoxiang Ge An Zeng Yi Arial Zeng Jianfeng Chen | 2021 | Cell Research2021，31，12： | 3 |

| 5 | Effects of Cure Pressure Induced Voids on the Mechanical Strength of Carbon/Epoxy Laminates显示文摘This work aims at designing a set of curing pressure routes to produce laminates with various void contents. The effects of various consolidation pressures resulting in different void contents on mechanical strength of carbon/epoxy laminates have been examined. Characterization of the voids, in terms of void volume fraction, void distribution,size, and shape, was performed by standard test, ultrasonic inspection and metallographic analysis. The interlaminar shear strength was measured by the short-beam method. An empirical model was used to predict the strength vs porosity. The predicted strengths conform well with the experimental data and voids were found to be uniformly distributed throughout the laminate. | Ling LIU, Boming ZHANG, Zhanjun WU and Dianfu WANGCenter for Composite Materials, Harbin Institute of Technology, Harbin 150001, ChinaProf., | 2005 | Journal of Materials Science & Technology2005，21，1： | 1 |

| 7 | Guided Wave Based Damage Detection Method for Aircraft Composite Structures under Varying Temperatures显示文摘Guided waves based damage detection methods using base signals offer the advantages of simplicity of signal generation and reception,sensitivity to damage,and large area coverage;however,applications of the technology are limited by the sensitivity to environmental temperature variations.In this paper,a Spearman Damage Index-based damage diagnosis method for structural health condition monitoring under varying temperatures is presented.First,a PZT sensor-based Guided wave propagation model is proposed and employed to analyze the temperature effect.The result of the analysis shows the wave speed of the Guided wave signal has higher temperature sensitivity than the signal fluctuation features.Then,a Spearman rank correlation coefficient-based damage index is presented to identify damage of the structure under varying temperatures.Finally,a damage detection test on a composite plate is conducted to verify the effectiveness of the Spearman Damage Index-based damage diagnosis method.Experimental results show that the proposed damage diagnosis method is capable of detecting the existence of the damage and identify its location under varying temperatures. | Dongyue Gao Yunlong Ma Zhanjun Wu Yuebin Zheng Hongbo Lu | 2021 | Structural Durability & Health Monitoring2021，15，1： | 1 |

| 12 | Monitoring of Real-Time Complex Deformed Shapes of Thin-Walled Channel Beam Structures Subject to the Coupling Between Bi-Axial Bending and Warping Torsion显示文摘Structural health monitoring(SHM)is a research focus involving a large category of techniques performing in-situ identification of structural damage,stress,external loads,vibration signatures,etc.Among various SHM techniques,those able to monitoring structural deformed shapes are considered as an important category.A novel method of deformed shape reconstruction for thinwalled beam structures was recently proposed by Xu et al.[1],which is capable of decoupling complex beam deformations subject to the combination of different loading cases,including tension/compression,bending and warping torsion,and also able to reconstruct the full-field displacement distributions.However,this method was demonstrated only under a relatively simple loading coupling cases,involving uni-axial bending and warping torsion.The effectiveness of the method under more complex loading cases needs to be thoroughly investigated.In this study,more complex deformations under the coupling between bi-axial bending and warping torsion was decoupled using the method.The set of equations for deformation decoupling was established,and the reconstruction algorithm for bending and torsion deformation were utilized.The effectiveness and accuracy of the method was examined using a thin-walled channel beam,relying on analysis results of finite element analysis(FEA).In the analysis,the influence of the positions of the measurement of surface strain distributions on the reconstruction accuracy was discussed.Moreover,different levels of measurement noise were added to the axial strain values based on numerical method,and the noise resistance ability of the deformation reconstruction method was investigated systematically.According to the FEA results,the effectiveness and precision of the method in complex deformation decoupling and reconstruction were demonstrated.Moreover,the immunity of the method to measurement noise was proven to be considerably strong. | Rui Lu Zhanjun Wu Qi Zhou Hao Xu | 2019 | Structural Durability & Health Monitoring2019，13，3： | 1 |
| 13 | Properties and mechanism of ionic liquid/silicone oil based magnetorheological fluids显示文摘A magnetorheological fluid(MRF)is a smart composite suspension composed of nonmagnetic liquid and soft magnetic particles.Carrier fluids can considerably influence the performance of MRFs;therefore,to investigate the effect of carrier fluids on MRFs,an SO/IL-MRF was prepared by mixing an ionic liquid(IL)with silicone oil(SO)in this study.Three types of MRF samples were prepared for experiments(pure SO,pure IL,and SO/IL).According to the experi-mental results,the SO/IL-MRF has better sedimentation stability than those based on pure SO and pure IL.Further,three methods were used to determine the shear yield stresses of the MRFs.The SO/IL-MRF achieved a higher shear yield stress than those of the other two because a network structure is formed between the ionic fragments and the molecular chains of the SO in the SO/IL-MRF.This increases the movement resistance of the particles in the carrier fluid,and it is unlike the mechanism of the IL-enhanced MRF.This work provides new ideas for improving the MRF performance. | Yu Tong Penghui Zhao Xiaoguang Li Ning Ma Xufeng Dong Chenguang Niu Zhanjun Wu Min Qi | 2022 | International Journal of Smart and Nano Materials2022，13，2： | 0 |
| 14 | STOCHASTIC ELASTO-PLASTIC FRACTURE ANALYSIS OF ALUMINUM FOAMS显示文摘Model I quasi-static nonlinear fracture of aluminum foams is analyzed by considering the effect of microscopic heterogeneity.Firstly,a continuum constitutive model is adopted to account for the plastic compressibility of the metallic foams.The yield strain modeled by a two-parameter Weibull-type function is adopted in the constitutive model.Then,a modified cohesive zone model is established to characterize the fracture behavior of aluminum foams with a cohesive zone ahead of the initial crack.The tensile traction versus local crack opening displacement relation is employed to describe the softening characteristics of the material.And a Weibull statistical model for peak bridging stress within the fracture process zone is used for considering microscopic heterogeneity of aluminum foams.Lastly,the inffuence of stochastic parameters on the curve of stress-strain is given.Numerical examples are given to illustrate the numerical model presented in this paper and the effects of Weibull parameters and material properties on J-integral are discussed. | Shiyong Sun Haoran Chen Xiaozhi Hu Zhanjun Wu | 2009 | Acta Mechanica Solida Sinica2009，22，3： | 0 |
| 15 | High-Performance D-A Copolymer Donor Based on Difluoroquinoxaline A-Unit with Alkyl-Chlorothiophene Substituents for Polymer Solar Cells显示文摘Side chain engineering with fluorine substitution is widely used to enhance photovoltaic performance of polymer donors in the research field of polymer solar cells(PSCs).However,fluorine substitution has disadvantages of complicated synthesis and high cost.Herein,we synthesized a novel D-A copolymer donor PBQ9 based on difluoroquinoxaline A-unit with chlorine substitution on its alkyl-thiophene side chains instead of fluorine substitution in the polymer donor PBQ6,which greatly shortens the synthetic route and reduces the cost.Interestingly,the optimized binary PSC with PBQ9 as polymer donor and m-TEH as acceptor demonstrated a high power conversion efficiency(PCE)of 18.81%(certified PCE of 18.33%by National Institute of Metrology,China)with a high fill factor of 80.59%,and the photovoltaic performance of the PSCs is insensitive to the different batches of the polymer donor.The results indicate that PBQ9 is a high-performance polymer donor and that chlorine substitution is an effective strategy to improve photovoltaic performance and reduce the cost of polymer donors. | Can Zhu Ke Hu Lei Meng Xiaolei Kong Wenbin Lai Shucheng Qin Beibei Qiu Jinyuan Zhang Zhanjun Zhang Yilei Wu Xiaojun Li Yongfang Li | 2023 | CCS Chemistry2023，5，10： | 0 |

| 19 | A Modified Principal Component Analysis Method for Honeycomb Sandwich Panel Debonding Recognition Based on Distributed Optical Fiber Sensing Signals显示文摘The safety and integrity requirements of aerospace composite structures necessitate real-time health monitoring throughout their service life.To this end,distributed optical fiber sensors utilizing back Rayleigh scattering have been extensively deployed in structural health monitoring due to their advantages,such as lightweight and ease of embedding.However,identifying the precise location of damage from the optical fiber signals remains a critical challenge.In this paper,a novel approach which namely Modified Sliding Window Principal Component Analysis(MSWPCA)was proposed to facilitate automatic damage identification and localization via distributed optical fiber sensors.The proposed method is able to extract signal characteristics interfered by measurement noise to improve the accuracy of damage detection.Specifically,we applied the MSWPCA method to monitor and analyze the debonding propagation process in honeycomb sandwich panel structures.Our findings demonstrate that the training model exhibits high precision in detecting the location and size of honeycomb debonding,thereby facilitating reliable and efficient online assessment of the structural health state. | Shuai Chen Yinwei Ma Zhongshu Wang Zongmei Xu Song Zhang Jianle Li Hao Xu Zhanjun Wu | 2024 | Structural Durability & Health Monitoring2024，18，2： | 0 |
| 20 | Shape Sensing of Thin Shell Structure Based on Inverse Finite Element Method显示文摘Shape sensing as a crucial component of structural health monitoring plays a vital role in real-time actuation and control of smart structures,and monitoring of structural integrity.As a model-based method,the inverse finite element method(iFEM)has been proved to be a valuable shape sensing tool that is suitable for complex structures.In this paper,we propose a novel approach for the shape sensing of thin shell structures with iFEM.Considering the structural form and stress characteristics of thin-walled structure,the error function consists of membrane and bending section strains only which is consistent with the Kirchhoff–Love shell theory.For numerical implementation,a new four-node quadrilateral inverse-shell element,iDKQ4,is developed by utilizing the kinematics of the classical shell theory.This new element includes hierarchical drilling rotation degrees-of-freedom(DOF)which enhance applicability to complex structures.Firstly,the reconstruction performance is examined numerically using a cantilever plate model.Following the validation cases,the applicability of the iDKQ4 element to more complex structures is demonstrated by the analysis of a thin wallpanel.Finally,the deformation of a typical aerospace thin-wall structure(the composite tank)is reconstructed with sparse strain data with the help of iDKQ4 element. | Zhanjun Wu Tengteng Li Jiachen Zhang Yifan Wu Jianle Li Lei Yang Hao Xu | 2022 | Structural Durability & Health Monitoring2022，16，1： | 0 |
