Small RNAs play an important role in plant immune responses. However, their regulatory function in induced systemic resistance（ISR） is nascent. Bacillus cereus AR156 is a plant growth-promoting rhizobacterium that induces ISR in Arabidopsis against bacterial infection. Here,by comparing small RNA profiles of Pseudomonas syringae pv. tomato（Pst） DC3000-infected Arabidopsis with and without AR156 pretreatment, we identified a group of Arabidopsis micro RNAs（mi RNAs） that are differentially regulated by AR156 pretreatment. mi R825 and mi R825 are two mi RNA generated from a single mi RNA *** blot analysis indicated that they were significantly downregulated in Pst DC3000-infected plants pretreated with AR156, in contrast to the plants without AR156 pretreatment. mi R825 targets two ubiquitin-protein ligases,while mi R825 targets toll-interleukin-like receptor（TIR）-nucleotide binding site（NBS） and leucine-rich repeat（LRR）type resistance（R） genes. The expression of these target genes negatively correlated with the expression of mi R825 and mi R825. Moreover, transgenic plants showing reduced expression of mi R825 and mi R825 displayed enhanced resistance to Pst DC3000 infection, whereas transgenic plants overexpressing mi R825 and mi R825 were more susceptible. Taken together, our data indicates that Bacillus cereus AR156 pretreatment primes ISR to Pst infection by suppressing mi R825 and mi R825 and activating the defense related genes they targeted.

Photonic Sensors 2015年第2期5卷 159-165页

作者： Jun ZHU Liuli QIN Shuxiang SONG Junwen ZHONG siyuan lin College of Electronic Engineering Guangxi Normal University Guilin 541004 China College of Mathematics and Statistics Guangxi Normal University Guilin 541004 China

Nowdays, the study of measurement of the biological field focuses on the research of improving surface plasmon resonance （SPR） in the fields of integration and detection sensitivity. We designed a kind of grating connected surface plasmon resonance sensor. Theoretically, we analyzed the wave vector and the. effective refractive index relations with the diffraction grating structure. Then we obtained the nanoparticles enhancement SPR structure with a resolution 10times higher than that of traditional SPR sensors. Also, we used the finite-difference time-domain （FDTD） analysis and simulation which showed that it was obvious with coupling effect by the nanoparticles enhancement SPR structure that the reflectance spectral bandwidth results validated the structure significantly which improved the sensitivity. Experimental results showed that the dynamic response of the designed sensor reached 10^-6 RIU （refractive index unit）. This study has the certain significance to long-distance and special sensing applications.

液晶屏(liquid crystal display, LCD)和有机发光半导体(organic light-emitting diode, OLED)屏的制造工艺复杂,其生产过程的每个阶段会不可避免地引入各种缺陷,影响产品的视觉效果及用户体验,甚至出现严重的质量问题。实现快速且精确的缺陷检测是提高产品质量和生产效率的重要手段。本文综述了近20年来基于机器视觉的液晶屏/OLED屏缺陷检测方法。首先给出了液晶屏/OLED屏表面缺陷的定义、分类及其产生的原因和缺陷的量化指标;指出了基于视觉的液晶屏/OLED屏表面缺陷检测的难点。然后重点阐述了基于图像处理的缺陷检测方法,包括介绍图像去噪和图像亮度矫正的图像预处理过程;考虑到所采集的液晶屏/OLED屏图像存在纹理背景干扰,对重复性纹理背景消除和背景抑制法进行分析;针对Mura缺陷边缘模糊等特点,总结改进的缺陷分割方法;阐述提取图像特征并使用支持向量机、支持向量数据描述和随机森林算法等基于特征识别的缺陷检测方法。接着综述了基于深度学习的缺陷检测方法,根据产线不同时期的样本数量分别总结了无监督学习、缺陷样本生成、迁移学习和监督学习的方法,其中无监督学习从基于生成对抗网络和自编码器两个方面进行阐述。随后梳理了通用纹理表面缺陷数据集和模型性能的评价指标。最后针对目前液晶屏/OLED屏缺陷检测方法存在的问题,对未来进一步的研究方向进行了展望。

宽高比为5∶1矩形断面的非线性自激气动力研究作为钝体空气动力学的基础性和前沿性研究,对钝体断面的非线性气动弹性行为分析有着重要的意义.采用节段模型强迫振动风洞试验,结合模型表面同步测压技术,分析了振幅对宽高比为5∶1矩形试验断面自激气动力频谱特性和表面压力分布特性的影响,并借助本征正交分解分析了模型表面压力的模态特征函数,进而探讨了非线性气动力产生的流动机理.试验及分析结果表明:5∶1矩形断面自激气动力的高次谐波分量仅在振幅不小于8°的扭转运动下显著,但线性分量随着振幅增加呈非线性变化;在竖向运动或在小于8°的扭转运动下,模型表面分离再附点位置靠近后缘且在一个周期内保持稳定,对应的压力模态为一阶对称分布,表明此时气动力仅由单一频率的主涡决定;在大于等于8°的扭转运动下,一个周期内模型表面的分离再附点位置主要集中在前缘,对应的压力模态中也同时出现了对称分布的第1阶和反对称分布的第2和第3阶,表明此时出现了多个不同频率的主要旋涡,而频率高于运动频率的二次涡主导了高阶模态,并由此产生了气动力的高次谐波分量.
