1Experimental study on the mechanical properties of rocks at high temperature显示文摘The mechanical properties of marble, limestone, and sandstone as well as the stress-strain curve, the varying characteristics of the peak strength, the peak strain and elastic modulus were studied by using the MTS810 Rock Mechanics Servo-controlled Testing System under the action of temperatures rang- ing from room temperature to 800℃ . Results show that (1) the peak strength and elastic modulus of marble fluctuate at the temperature from normal to 400 ℃ ; and they decrease gradually over 400℃ . (2) With the rise of the temperature, the peak strength and elastic modulus of limestone show downward trend from normal temperature to 200 ℃ ; have little change from 200 ℃ to 600 ℃; and decrease sharply over 600 ℃ . (3) The peak strength of sandstone shows a downward trend while a little change for elastic modulus at normal temperature to 200 ℃ ; and from 200 ℃ to 600 ℃ , the peak strength of sandstone in- creases while a little change for elastic modulus; the peak strength and elastic modulus decrease rap- idly at the temperature over 600 ℃ . (4) The peak strain of limestone shows little change at normal tem- perature to 600 ℃ , however, the peak strain increases rapidly over 600 ℃; and for marble and sandstone, the peak strain decreases with the rise of the temperature from normal temperature to 200℃ , the peak strain increases rapidly over 200℃. The result can provide valuable references for the rock engineering design at high temperature.ZHANG LianYing MAO XianBiao LU AiHong 2009Science China(Technological Sciences)2009,52,3:30
2Effect of specimen size on energy dissipation characteristics of red sandstone under high strain rate显示文摘In this experiment, red sandstone specimens, having slenderness ratios of 0.5, 0.7, 0.9 and 1.1 respectively, were subjected to blow tests using a Split Hopkinson Pressure Bar(SHPB) system at a pressure of 0.4 atmospheres. In this paper, we have analyzed the effect of slenderness ratio on the mechanical properties and energy dissipation characteristics of red sandstone under high strain rates. The processes of compaction, elastic deformation and stress softening deformation of specimens contract with an increase in slenderness ratio, whilst the nonlinear deformation process extends correspondingly. In addition, degrees of damage of specimens reduced gradually and the type of destruction showed a transformation trend from stretching failure towards shear failure when the slenderness ratio increased. A model of dynamic damage evolution in red sandstone was established and the parameters of the constitutive model at different ratios of length to diameter were determined. By comparison with the experimental curve, the accuracy of the model, which could reflect the stress–strain dynamic characteristics of red sandstone, was verified. From the view of energy dissipation, an increase in slenderness ratio of a specimen decreased the proportion of energy dissipation and caused a gradual fall in the capability of energy dissipation during the specimen failure process. To some extent, the study indicated the effects of slenderness ratios on the mechanical properties and energy dissipation characteristics of red sandstone under the high strain rate, which provides valuable references to related engineering designs and academic researches.Li Ming Mao Xianbiao Lu Aihong Tao Jing Zhang Guanghui Zhang Lianying Li Chong 2014International Journal of Mining Science and Technology2014,24,2:24
3Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding.Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang 2020Science China(Life Sciences)2020,63,11:8
4Digital/Analog Simulation Platform for Distributed Power Flow Controller Based on ADPSS and dSPACE显示文摘Distributed power flow controller,which is among the most powerful distributed flexible transmission equipments,is still only in the stage of the oretical research and digital simulation.In order to promote the engineering demonstration of a distributed power flow controller,it is urgent to establish a digital/analog simulation platform that supports closed-loop real-time simulation of a distributed power flow controller.In this paper,the electromagnetic transient model of a distributed power flow controller is established on ADPSS(advanced digital power system simulator).The rapid control prototype realized by dSPACE is connected to ADPSS to form a digital/analog simulation platform for a distributed power flow controller.Through a voltage control and power flow control simulation of the test system with a distributed power flow controller,the correctness and effectiveness of the constructed simulation platform are verified,which provides a new way for the verification of the new theory of a distributed power flow controller.Aihong Tang Zhijian Lu Huiyuan Yang Xinpeng Zou Yong Huang Xu Zheng 2021CSEE Journal of Power and Energy Systems2021,7,1:6

6Autophagy targets Hd1 for vacuolar degradation to regulate rice flowering显示文摘Flowering time(heading date)is a critical agronomic trait that determines the yield and regional adaptability of crops.Heading date 1(Hd1)is a central regulator of photoperiodic flowering in rice(Oryza sativa).However,how the homeostasis of Hd1 protein is achieved is poorly understood.Here,we report that the nuclear autophagy pathway mediates Hd1 degradation in the dark to regulate flowering.Loss of autophagy function results in an accumulation of Hd1 and delays flowering under both short-day and long-day conditions.In the dark,nucleus-localized Hd1 is recognized as a substrate for autophagy and is subjected to vacuolar degradation via the autophagy protein OsATG8.The Hd1-0sATG8 interaction is required for autophagic degradation of Hd1 in the dark.Our study reveals a new mechanism by which Hd1 protein homeostasis is regulated by autophagy to control rice flowering.Our study also indicates that the regulation of flowering by autophagic degradation of Hd1 orthologs may have arisen over the course of mesangiosperm evolution,which would have increased their flexibility and adaptability to the environment by modulating flowering time.Zhi Hu Zhipan Yang Yi Zhang Aihong Zhang Qingtao Lu Ying Fang Congming Lu 2022Molecular Plant2022,15,7:3
7LncRNA HOTAIR promotes endometrial fibrosis by activating TGF-β1/Smad pathway显示文摘Homeobox transcript antisense RNA(HOTAIR)is a long non-coding RNA associated with a number of fibrosis-related diseases.The aim of this study was to investigate the specific role of HOTAIR in the development of endometrial fibrosis and to identify the molecular mechanisms underlying this process.Reverse transcription-quantitative polymerase chain reaction(RT-qPCR)was used to determine the expression levels of HOTAIR in samples of intrauterine adhesion(lUA)tissue and in endometrial stromal cells(ESCs)that had been treated with transforming growth factor beta 1(TGF-β1).Additionally,we transfected ESCs with either overexpression plasmid(pcDNA-HOTAIR)or silencing construct(si-HOTAIR)and then treated these cells with TGF-β1.We then performed RTqPCR and western blot analysis,along with cell proliferation and apoptosis assays,to investigate the effects of HOTAIR on the transdifferentiation of ESCs into myofibroblasts.The results showed that the expression levels of HOTAIR were significantly elevated in IUA tissue and in ESCs that had been treated with TGF-β1.The overexpression of HOTAIR had a pro-fibrotic effect on ESCs,while the silencing of HOTAIR exerted an anti-fibrotic effect.Most importantiy,the protein expression levels of p-Smad2 and p-Smad3 were significantly upregulated in TGF-β1.treated ESCs transfected with pcDNA-HOTAIR and were downregulated after transfection with si-HOTAIR constructs.These data indicate that HOTAIR promotes endometrial fibrosis by activating the TGF-β1/Smad signaling pathway,suggesting that the inhibition of HOTAIR may represent a promising therapeutic option for suppressing endometrial fibrosis.Jianhong Wu Lingge Jin Yudi Zhang Aihong Duan Juhong Liu Ziwen Jiang Liang Huang Jing Chen Zhaohui Liu Dan Lu Yinmei Dai 2020Acta Biochimica et Biophysica Sinica2020,52,12:3
8Pentatricopeptide repeat protein PHOTOSYSTEM I BIOGENESIS FACTOR2 is required for splicing of ycf3显示文摘To gain a better understanding of the molec-ular mechanisms of photosystem!(PSI)biogenesis,wecharacterized the Arabidopsis thaliana photosystem l bio-genesis factor 2(pbf2)mutant,which lacks PSl complex.PBF2 encodes a P-class pentatricopeptide repeat(PPR)protein.In the pbf2 mutants,we observed a striking de-crease in the transcript level of only one gene,thechloroplast gene ycf3,which is essential for PSl assembly.Further analysis of ycf3 transcripts showed that PBF2 isspecifically required for the splicing of ycf3 intron 1.Computational prediction of binding sequences and elec-trophoretic mobility shift assays reveal that PBF2 specifi-cally binds to a sequence in ycf3 intron 1.Moreover,we found that PBF2 interacted with two general factors forgroup ll intron splicing CHLOROPLAST RNA SPLICING2-AsSOCIATED FACTOR1(CAF1)and CAF2,and facilitated theassociation of these two factors with ycf3 intron 1.Ourresults suggest that PBF2 is specifically required for thesplicing of ycf3 intron 1 through cooperating with CAF1and CAF2.Our results also suggest that additional proteinsare required to contribute to the specificity of CAF-dependent group ll intron splicing.Xuemei Wang Zhipan Yang Yi Zhang Wen Zhou Aihong Zhang Congming Lu 2020Journal of Integrative Plant Biology2020,62,11:2
9Effect of a preload force on anchor system frequency显示文摘The interrelationship between preload forces and natural frequencies of anchors was obtained from the structure of an anchor and its mechanical characteristics. We established a numerical model for the dynamic analysis of a bolt support system taking into consideration the working surroundings of the anchor. The natural frequency distribution of the system under various preload forces of the anchor was analyzed with ANSYS. Our results show that each order of the system frequency varied with an increase in preload forces. A single order frequency decreased with an increase in the preload force. A preload force affected low-order frequencies more than high-order frequencies. We obtained a functional relationship by fitting preload forces and fundamental frequencies, which was in agreement with our theretical considerations. This study provides theoretical support for the detection of preload forces.Lu Aihong Xu Jinhai Liu Haishun 2013International Journal of Mining Science and Technology2013,23,1:2

14Pijx confers broad-spectrum seedling and panicle blast resistance by promoting the degradation of ATP β subunit and OsRbohC-mediated ROS burst in rice显示文摘Rice blast,caused by the fungal pathogen Magnaporthe oryzae,is one of the most important diseases of rice.Utilization of blast-resistance genes is the most economical,effective,and environmentally friendly way to control the disease.However,genetic resources with broad-spectrum resistance(BSR)that is effective throughout the rice growth period are rare.In this work,using a genome-wide association study,we identify a new blast-resistance gene,Pijx,which encodes a typical CC-NBS-LRR protein.Pijx is derived from a wild rice species and confers BSR to M.oryzae at both the seedling and panicle stages.The functions of the resistant haplotypes of Pijx are confirmed by gene knockout and overexpression experiments.Mechanistically,the LRR domain in Pijx interacts with and promotes the degradation of the ATP synthase β subunit(ATPb)via the 26S proteasome pathway.ATPb acts as a negative regulator of Pijx-mediated panicle blast resistance,and interacts with OsRbohC to promote its degradation.Consistently,loss of ATPb function causes an increase in NAPDH content and ROS burst.Remarkably,when Pijx is introgressed into two japonica rice varieties,the introgression lines show BSR and increased yields that are approximately 51.59%and 79.31%higher compared with those of their parents in a natural blast disease nursery.In addition,we generate PPL^(Pijx Pigm) and PPL^(Pijx Piz-t) pyramided lines and these lines also have higher BSR to panicle blast compared with Pigm-or Piz-t-containing rice plants.Collectively,this study demonstrates that Pijx not only confers BSR to M.oryzae but also maintains high and stable rice yield,providing new genetic resources and molecular targets for breeding rice varieties with broad-spectrum blast resistance.Ning Xiao Yunyu Wu Xiaoxiang Zhang Zeyun Hao Zichun Chen Zefeng Yang Yue Cai Ruyi Wang Ling Yu Zhiping Wang Yue Lu Wei Shi Cunhong Pan Yuhong Li Changhai Zhou Jianju Liu Niansheng Huang Guangqing Liu Hongjuan Ji Shuhao Zhu Shuai Fang Yuese Ning Aihong Li 2023Molecular Plant2023,16,11:0
