| 1 | THE EFFECTS OF THREE-DIMENSIONAL PENNY-SHAPED CRACKS ON ZONAL DISINTEGRATION OF THE SURROUNDING ROCK MASSES AROUND A DEEP CIRCULAR TUNNEL显示文摘In this study, it was assumed that three-dimensional penny-shaped cracks existed in deep rock masses. A new non-Euclidean model was established, in which the effects of pennyshaped cracks and axial in-situ stress on zonal disintegration of deep rock masses were taken into account. Based on the non-Euclidean model, the stress intensity factors at tips of the pennyshaped cracks were determined. The strain energy density factor was applied to investigate the occurrence of fractured zones. It was observed from the numerical results that the magnitude and location of fractured zones were sensitive to micro- and macro-mechanical parameters, as well as the value of in-situ stress. The numerical results were in good agreement with the experimental data. | Xiaoping Zhou Qihu Qian Hanfei Song | 2015 | Acta Mechanica Solida Sinica2015，28，6： | 2 |
| 2 | Highly Stretchable and Permeable Conductors Based on Shrinkable Electrospun Fiber Mats显示文摘Wearable on-skin electrodes or conductors should be vapor permeable,strain-insensitive,isotropically stretchable and stable under cyclic stretching.Various strategies have been proposed to prepare the required conductors up to now;however,it is a challenge to fabricate them with above properties in a simple manner.In this paper,a highly permeable and stretchable conductor based on electrospun fluorine rubber fiber mat is reported.The fibers are pre-stretched in electric field during electrospinning,and they shrink isotropically by~35-40%in area after being detached from the substrate.The obtained fiber mat conductor demonstrates high stretchability up to~170%,and the resistance changes only 0.8 under 60%strain,which is superior to many other strain-insensitive conductors.The conductor possesses high stability,no cracks or structure damage are observed after washing and cyclic stretching.Moreover,the conductor is vapor permeable with a water vapor transmission rate of~850 g m−2 day−1,which is comparable to the normal water evaporation in ambient conditions,indicating that it would not disturb the sweat evaporation when being used on skin.The conductor is successfully used as stretchable yarns and electromyography(EMG)electrodes,showing high reliability in E-textiles and on-skin applications. | Qingsong Li Chen Ding Wei Yuan Ruijie Xie Xiaomeng Zhou Yang Zhao Mei Yu Zijian Yang Jing Sun Qiong Tian Fei Han Hanfei Li Xinping Deng Guanglin Li Zhiyuan Liu | 2021 | Advanced Fiber Materials2021，3，5： | 1 |
| 3 | High-quality Fagopyrum esculentum genome provides insights into the flavonoid accumulation among different tissues and self-incompatibility显示文摘Common buckwheat(Fagopyrum esculentum)and Tartary buckwheat(Fagopyrum tataricum),the two most widely cultivated buckwheat species,differ greatly in flavonoid content and reproductive mode.Here,we report the first high-quality and chromosome-level genome assembly of common buckwheat with 1.2 Gb.Comparative genomic analysis revealed that common buckwheat underwent a burst of long terminal repeat retrotransposons insertion accompanied by numerous large chromosome rearrangements after divergence from Tartary buckwheat.Moreover,multiple gene families involved in stress tolerance and flavonoid biosynthesis such as multidrug and toxic compound extrusion(MATE)and chalcone synthase(CHS)underwent significant expansion in buckwheat,especially in common buckwheat.Integrated multi-omics analysis identified high expression of catechin biosynthesis-related genes in flower and seed in common buckwheat and high expression of rutin biosynthesis-related genes in seed in Tartary buckwheat as being important for the differences in flavonoid type and content between these buckwheat species.We also identified a candidate key rutindegrading enzyme gene(Ft8.2377)that was highly expressed in Tartary buckwheat seed.In addition,we identified a haplotype-resolved candidate locus containing many genes reportedly associated with the development of flower and pollen,which was potentially related to self-incompatibility in common buckwheat.Our study provides important resources facilitating future functional genomics-related research of flavonoid biosynthesis and selfincompatibility in buckwheat. | Qiang He Dan Ma Wei Li Longsheng Xing Hongyu Zhang Yu Wang Cailian Du Xuanzhao Li Zheng Jia Xiuxiu Li Jianan Liu Ze Liu Yuqing Miao Rui Feng Yang Lv Meijia Wang Hongwei Lu Xiaochen Li Yao Xiao Ruyu Wang Hanfei Liang Qinghong Zhou Lijun Zhang Chengzhi Liang Huilong Du | 2023 | Journal of Integrative Plant Biology2023，65，6： | 0 |
| 4 | Analysis and Design of Multi-aspect SAR System for Compressive Sensing-Based 3D Imaging显示文摘This paper focuses on the analysis and design of Multi-aspect SAR(MuSAR) system for Compressive sensing-based(CS-based) 3D imaging. For this purpose,the Point ambiguous function(PAF) is proposed to analyze the factors that dominate the Mutual coherence(MC) of MuSAR sensing matrix. The PAF contacts with the parameters and configuration of MuSAR system directly and is easy to manipulate. With PAF, the present study analyzes the factors that dominate the performance of CS-based MuSAR 3D imaging. First of all, the stochastic waveform is an excellent selection. Second, the angular-frequency-diversity can improve the robustness of3 D imaging. Finally, the finer sampling of received data could improve the robustness of MuSAR 3D imaging. Simulation experiments show the validity of conclusion. | ZHOU Hanfei SU Yi XI Zemin LU Jianbin | 2014 | Chinese Journal of Electronics2014，23，3： | 0 |
