| 1 | HY5-HDA9 Module Transcriptionally Regulates Plant Autophagy in Response to Light-to-Dark Conversion and Nitrogen Starvation显示文摘Light is arguably one of the most important environmental factors that determines virtually all aspects of plant growth and development,but the molecular link between light signaling and the autophagy pathway has not been elucidated in plants.In this study,we demonstrate that autophagy is activated during light-to-dark conversion though transcriptional upregulation of autophagy-related genes(ATGs).We showed that depletion of the ELONGATED HYPOCOTYL 5(HY5),a key component of light signaling,leads to enhanced autophagy activity and resistance to extended darkness and nitrogen starvation treatments,contributing to higher expression oiATGs.HY5 interacts with and recruits HISTONE DEACETYLASE 9(HDA9)to ATG5 and ATG8e loci to repress their expression by deacetylation of the Lys9 and Lys27 of histone 3.Furthermore,we found that both darkness and nitrogen depletion induce the degradation of HY5 via 26S proteasome and the concomitant disassociation of HDA9 from ATG5 and ATG8e loci,leading to their depression and thereby activated autophagy.Genetic analysis further confirmed that HY5 and HDA9 act synergistically and function upstream of the autophagy pathway.Collectively,our study unveils a previously unknown transcriptional and epigenetic network that regulates autophagy in response to light-to-dark conversion and nitrogen starvation in plants. | Chao Yang Wenjin Shen Lianming Yang Yun Sun Xibao Li Minyi Lai Juan Wei Chaojun Wang Yingchao Xu Faqiang Li Shan Liang Chengwei Yang Shangwei Zhong Ming Luo Caiji Gao | 2020 | Molecular Plant2020，13，3： | 8 |
| 2 | SINAT E3 ligases regulate the stability of the ESCRT component FREE1 in response to iron deficiency in plants显示文摘The endosomal sorting complex required for transport (ESCRT) machinery is an ancient, evolutionarily conserved membrane remodeling complex that is es-sential for multivesicular body (MVB) biogenesis in eu-karyotes. FYVE DOMAIN PROTEIN REQUIRED FOR EN-DOSOMAL SORTING 1 (FREE1), which was previously identified as a plant-specific ESCRT component, modu-lates MVB-mediated endosomal sorting and autophagic degradation. Although the basic cellular functions of FREE1 as an ESCRT component have been described, the regulators that control FREE1 turnover remain unknown. Here, we analyzed how FREE1 homeostasis is mediated by the RING-finger E3 ubiquitin ligases, SINA of Arabi-dopsis thaliana (SINATs), in response to iron deficiency. Under iron-deficient growth conditions, SINAT1-4 were induced and ubiquitinated FREE1, thereby promoting its degradation and relieving the repressive effect of FREE1 on iron absorption. By contrast, SINAT5, another SINAT member that lacks ubiquitin ligase activity due to the absence of the RING domain, functions as a protector protein which stabilizes FREE1. Collectively, our findings uncover a hitherto unknown mechanism of homeostatic regulation of FREE1, and demonstrate a unique regu-latory SINAT–FREE1 module that subtly regulates plant response to iron deficiency stress. | Zhidan Xiao Chao Yang Chuanliang Liu Lianming Yang Shuhong Yang Jun Zhou Faqiang Li Liwen Jiang Shi Xiao Caiji Gao Wenjin Shen | 2020 | Journal of Integrative Plant Biology2020，62，9： | 2 |

| 4 | Proton radiography of magnetic fields generated with an open-ended coil driven by high power laser pulses显示文摘Recently generation of strong magnetic(B)fields has been demonstrated in capacitor coils heated by high power laser pulses[S.Fujioka et al.,Sci.Rep.3,1170(2013)].This paper will present a direct measurement of B field generated with an open-ended coil target driven by a nanosecond laser pulse using ultrafast proton radiography.The radiographs are analyzed with particle-tracing simulations.The B field at the coil center is inferred to be ~50 T at an irradiance of ~5×10^(14) W·cm^(-2).The B field generation is attributed to the background cold electron flow pointing to the laser focal spot,where a target potential is induced due to the escape of energetic electrons. | Guoqian Liao Yutong Li Baojun Zhu Yanfei Li Fang Li Mengchao Li Xuan Wang Zhe Zhang Shukai He Weiwu Wang Feng Lu Faqiang Zhang Lei Yang Kainan Zhou Na Xie Wei Hong Yuqiu Gu Zongqing Zhao Baohan Zhang Jie Zhang | 2016 | Matter and Radiation at Extremes2016，1，4： | 1 |

| 10 | Angular dependent NEXAFS study of the molecular orientation of PTCDA multilayers on Au (111) surface显示文摘The molecular orientation of perylene-3,4,9,10-tetracarboxylic acid dianhydride (PTCDA) multilayers adsorbed on Au (111) surface has been investigated using angular dependent O K-edge near edge X-ray absorption fine structure (NEXAFS) spectroscopy. The significant angular dependence of important resonant structures (π* and σ*) reveals that PTCDA molecules adopt an ordered geometry on the substrate surface. The average tilt angle of the PTCDA molecular planes is 27°±10° from the Au (111) surface. | CAO Liang ZHANG WenHua HAN YuYan CHEN TieXin ZHENG ZhiYuan WAN Li XU FaQiang IBRAHIM Kurash QIAN HaiJie WANG JiaOu | 2011 | Chinese Science Bulletin2011，56，33： | 1 |

| 12 | Enhanced energy storage properties of barium titanate ceramics made from surface modified particles显示文摘Surface modification of barium titanate particles has been carried out using a wet chemical method.The microstructural and dielectric properties of the ceramics made from surface modified particles were extensively investigated by X-ray diffraction,scanning electron microscopy,transmission electron microscopy,and dielectric properties measurements.The breakdown strength increased by 69%and 117%for the Al_(2)O_(3) and B_(2)O_(3)–SiO_(2) modified ceramics,respectively.An energy storage density of up to 3.2 J/cm^(3) has been obtained.The suppression of grain boundary electron transport and reduction in pore defects lead to the energy storage properties enhancement of the modified ceramics.These results indicated that surface modification of ceramic particles is a promising approach to obtain dielectric ceramics with high energy storage density. | Zhifu Liu Zhiqiang Zhang Faqiang Zhang Yongxiang Li | 2013 | Journal of Advanced Dielectrics2013，3，3： | 1 |
| 13 | Unusual local electric field concentration in multilayer ceramic capacitors显示文摘Local electric-field around multitype pores(dielectric pore,interface pore,electrode pore)in multilayer ceramic capacitors(MLCCs)was investigated using Kelvin probe force microscopy combined with the finite element simulation to understand the effect of pores on the electric reliability of MLCCs.Electricfield is found to be concentrated significantly in the vicinity of these pores and the strength of the local electric-field is 1.5e5.0 times of the nominal strength.Unexpectedly,the concentration degree of the pores in the inner electrode is much higher than that in the dielectrics and dielectric-electrode interfaces.Meanwhile,geometry orientations are found to have a remarkable influence on the local electric field strength.The pores act as an insulation degradation precursor via local electric,thermal center,and oxygen vacancies accumulation center.Such unusual local electric field concentration of multitype pores can provide new insights into the understanding of insulation degradation evolution,processing tailoring and design optimization for MLCCs. | Wentong Du Huarong Zeng Weiwei Yang Kunyu Zhao Faqiang Zhang Guorong Li Yongxiang Li Zhifu Liu | 2023 | Journal of Materiomics2023，9，2： | 0 |
| 14 | Identification model of multi-layered neural network parameters and its applications in the petroleum production显示文摘This paper creates a LM (Levenberg-Marquardt) algorithm model which is appropriate to solve the problem about weights value of feedforward neural network. On the base of this model, we provide two applications in the oilfield production. Firstly, we simulated the functional relationships between the petrophysical and electrical properties of the rock by neural networks model, and studied oil saturation. Under the precision of data is confirmed, this method can reduce the number of experiments. Secondly, we simulated the relationships between investment and income by the neural networks model, and studied invest saturation point and income growth rate. It is very significant to guide the investment decision. The research result shows that the model is suitable for the modeling and identification of nonlinear systems due to the great fit characteristic of neural network and very fast convergence speed of LM algorithm. | Liu Ranbing Liu Leiming Zhang Faqiang Li Changhua | 2008 | Engineering Sciences2008，6，2： | 0 |
| 15 | Metric Learning with Relative Distance Constraints:A Modified SVM Approach显示文摘Distance metric learning plays an important role in many machine learning tasks. In this paper, we propose a method for learning a Mahanalobis distance metric. By formulating the metric learning problem with relative distance constraints, we suggest a Relative Distance Constrained Metric Learning (RDCML) model which can be easily implemented and effectively solved by a modified support vector machine (SVM) approach. Experimental results on UCI datasets and handwritten digits datasets show that RDCML achieves better or comparable classification accuracy when compared with the state-of-the-art metric learning methods. | Changchun Luo Mu Li Hongzhi Zhang Faqiang Wang David Zhang Wangmeng Zuo | 2015 | 国际计算机前沿大会会议论文集2015，，1： | 0 |
