14An Intelligent Detection Method for Optical Remote Sensing Images Based on Improved YOLOv7显示文摘To address the issue of imbalanced detection performance and detection speed in current mainstream object detection algorithms for optical remote sensing images,this paper proposes a multi-scale object detection model for remote sensing images on complex backgrounds,called DI-YOLO,based on You Only Look Once v7-tiny(YOLOv7-tiny).Firstly,to enhance the model’s ability to capture irregular-shaped objects and deformation features,as well as to extract high-level semantic information,deformable convolutions are used to replace standard convolutions in the original model.Secondly,a Content Coordination Attention Feature Pyramid Network(CCA-FPN)structure is designed to replace the Neck part of the original model,which can further perceive relationships between different pixels,reduce feature loss in remote sensing images,and improve the overall model’s ability to detect multi-scale objects.Thirdly,an Implicitly Efficient Decoupled Head(IEDH)is proposed to increase the model’s flexibility,making it more adaptable to complex detection tasks in various scenarios.Finally,the Smoothed Intersection over Union(SIoU)loss function replaces the Complete Intersection over Union(CIoU)loss function in the original model,resulting in more accurate prediction of bounding boxes and continuous model optimization.Experimental results on the High-Resolution Remote Sensing Detection(HRRSD)dataset demonstrate that the proposed DI-YOLO model outperforms mainstream target detection algorithms in terms of mean Average Precision(mAP)for optical remote sensing image detection.Furthermore,it achieves Frames Per Second(FPS)of 138.9,meeting fast and accurate detection requirements.Chao Dong Xiangkui Jiang 2023Computers, Materials & Continua2023,77,12:0
15Assumed stress quasi-conforming triangular element for couple stress theory显示文摘In this paper, a 3-node triangular element for couple stress theory is proposed based on the assumed stress quasi-conforming method. The formulation starts from polynomial approximation of stresses. Then the stress-function matrix is treated as the weighted function to weaken the strain-displacement equations. Finally, the string-net functions are introduced to calculate strain integration and the stress smooth technique is adopted to improve the stress accuracy. Numerical results show that the proposed new model can pass the C^(0-1) patch test with excellent precision, does not exhibit extra zero energy modes and can capture the scale effects of microstructure.Changsheng Wang Xiangkui Zhang Ping Hu 2017Acta Mechanica Solida Sinica2017,30,4:0

1818-DOF Triangular Quasi-Conforming Element for Couple Stress Theory显示文摘The basic idea of quasi-conforming method is that the strain-dis-placement equations are weakened as well as the equilibrium equations.In this paper,an 18-DOF triangular element for couple stress theory is proposed within the framework of quasi-conforming technique.The formulation starts from truncated Taylor expansion of strains and appropriate interpolation functions are chosen to calculate strain integration.This element satisfies C0 continuity with second order accuracy and weak C1 continuity simultaneously.Numerical examples demonstrate that the proposed model can pass the C0??1 patch test and has high accuracy.The element does not exhibit extra zero energy modes and can capture the scale effects of microstructure.Xiangkui Zhang ChangshengWang Ping Hu 2016Computer Modeling in Engineering & Sciences2016,,6:0
19Multifunctional peptide conjugated amphiphilic cationic copolymer for enhancing ECs targeting, penetrating and nuclear accumulation显示文摘Gene therapy has drawn great attention in the treatments of many diseases,especially for cardiovascular diseases.However,the development of gene carriers with low cytotoxicity and multitargeting function is still a challenge.Herein,the multitargeting REDV-G-TATG-NLS peptide was conjugated to amphiphilic cationic copolymer poly(e-caprolactone-co-3(S)-methyl-morpho-line-2,5-dione)-g-polyethyleneimine(PCLMD-g-PEI)via a heterobifunctional orthopyridyl disulfde-poly(ethylene glycol)-N-hydroxysuccinimide(OPSS-PEG-NHS)linker to prepare PCLMD-g-PEI-PEG-REDV-G-TAT-G-NLS copolymers with the aim to develop the gene carriers with low cytotoxicity and high transfection efficiency.The multitargeting micelles were prepared from PCLMD-g-PEI-PEG-REDV-G-TAT-G-NLS copolymers by self-assembly method and used to load pEGFP-ZNF580 plasmids(pDNA)to form gene complexes for enhancing the proliferation and migration of endothelial cells(ECs).The loading pDNA capacity was proved by agarose gel electrophoresis assay.These multitargeting gene com-plexes exhibited low cytotoxicity by 3-(4,-dimethylthia-zol-2-yl)-2,5-diphenyltetrazolium bromide assay.The high internalization efficiency of these gene complexes was confirmed by flow cytometry.The results of in vitro transfection demonstrated that these multitargeting gene complexes possessed relatively high transfection effi-ciency.The rapid migration of ECs transfected by these gene complexes was verified by wound healing assay.Owing to ECs-targeting ability,cell-penetrating ability and nuclear targeting capacity of REDV-G-TAT-G-NLS pep-tide,the multitargeting polycationic gene carrier with low cytotoxicity and high transfection efficiency has great potential in gene therapy.Xinghong Duo Lingchuang Bai Jun Wang Jintang Guo Xiangkui Ren Shihai Xia Wencheng Zhang Abraham Domb Yakai Feng 2020Frontiers of Chemical Science and Engineering2020,14,5:0
