虚拟财产的法律界定与立法保护
The Legal Nature of Virtual Properties and Relative Legislative Protection
 [PDF]


Open Journal of Legal Science (OJLS) , 2014, DOI: 10.12677/OJLS.2014.23003
Abstract:

随着互联网时代的到来,网络虚拟财产应运而生。然而,网络虚拟财产却不同于传统法律意义上的物。目前关于虚拟财产法律属性的界定主要有三种:物权说,知识产权说及债权说。根据虚拟财产的特征,将虚拟财产权界定为债权更为合适,反映的是虚拟财产背后的游戏供应商与玩家之间的服务合同关系。同时应当在立法上予以完善,更好地保护虚拟财产,以促进网络经济健康、有序发展。
With the development of internet, virtual properties appear. However, they are distinctive from those traditional properties of civil law. Currently, there are three opinions about legal nature of virtual properties: real rights, intellectual properties and obligatory right. In accordance with the features of virtual properties, it’s suitable to define it as a kind of obligatory right, as it reflects the contractual relationship between network game suppliers and online gamers. Meanwhile, it’s vital to improve relative legislation so as to protect virtual properties which can make sure that the net economy can develop orderly.

《诸子百家大辞典》评介

天府新论 , 2000,
Abstract: 黄开国、李刚、陈兵、舒大刚、黄小石主编的《诸子百家大辞典》由四川人民出版社推出。全书二百万字,收词七千余条,是国内外第一部全面介绍儒、释、道三教与兵家、法家、道家、纵横家、名家、阴阳家等各家各派的学术工具书。全国政协副主席、中国佛协会长赵朴初先生题字,北京大学博士导师、著名哲学家张岱年教授、武汉大学博士导师、著名哲学史家萧父教授作序。该书的出版,为系统了解中国传统文化提供了一部有价值的工具书。中国古代文化源远而流长,多元而互补。在其几千年的发展中,形成了儒、释、道三教鼎立,又有法家、兵家、名家、阴阳家等其他众多学术流派并立,诸子百家相互对立,又相互融合的学术格局。把中国传统文化单纯地归结为一

L-乳酸脱氢酶基因在乳酸乳球菌KLDS4.0325中的表达

- , 2015, DOI: 10.13982/j.mfst.1673-9078.2015.4.011
Abstract: 本文研究了在mRNA转录水平上三种L-乳酸脱氢酶基因在乳酸乳球菌KLDS4.0325不同生长阶段的表达情况。以16s rRNA作为内参基因,应用实时荧光定量PCR技术测定不同生长阶段的菌体中L-乳酸脱氢酶基因(ldh、ldhX和ldhB)表达的动态变化规律。该菌株的生长曲线呈S型,培养2~6 h为菌体的生长对数期,随后进入稳定期。生长曲线的测定表明该菌株生长力极其旺盛;16s rRNA、ldh、ldhX和ldhB基因的扩增效率曲线显示,内参基因与目的基因的扩增效率一致且接近100%,这说明利用相对荧光定量法能够较好的反应目的基因的表达量;ldh、ldhX和ldhB基因在菌体生长的3个时间点(6 h、9 h和12 h)都有一定量的表达,随着菌体的不断生长,基因表达的变化均呈现显著性上升趋势,且上升幅度不断增加,在12 h时基因表达量达到最大值。其中ldh基因在的表达量在菌体生长的3个时间点存在显著性差异,而ldhX、ldhB基因的表达量存在极显著差异。
The expressions of three L-lactate dehydrogenase genes at the mRNA transcription level during the different phases of Lactococcus lactis KLDS4.0325 growth were investigated in this study. Dynamic variations in the expressions of the three L-lactate dehydrogenase genes (ldh , ldhB, and ldhX) during the different growth phases were detected by fluorescence-based quantitative real time polymerase chain reaction (PCR), using the 16s rRNA gene as the internal standard. The growth curves of the strain were observed to be ‘S’-shaped, with the strains reaching the exponential phase of growth within 2~6 h of culture; subsequently, the cells remained in the stationary phase. The growth curve revealed the extremely strong vitality of the cells; the amplification efficiency curve of the 16s rRNA, ldh, ldhB, and ldhX genes indicated similar amplification efficiencies (close to 100%) of the reference and target genes. These results indicated that the fluorescence-based quantitative real time PCR method reflected the expression level of the target genes adequately. The ldh, ldhB, and ldhX genes were expressed to specific levels during the three time points (6 h, 9 h, and 12 h) of strain growth. In addition to the growth of the strain, the gene expression levels demonstrated a significant upward trend, with a continuous amplitude of increase; the highest expression level was observed at 12 h post-initiation. The levels of expression of the ldh gene significantly differed among the three time points; in addition, the expression of ldhB significantly differed from that of ldhX.
基于分层滤波技术的冲击噪声检测与去除算法

Abstract:
本文提出了一种基于分层滤波技术的图像随机值冲击噪声检测和去除算法。为了解决经典自适应中心加权中值滤波技术在较高噪声比率下漏检严重的问题,我们采取逐级设置由高到低的噪声值判决门限来层层筛选噪声,利用不同高度的门限甄别出不同信赖度的冲击噪点,同时更新已检测出的噪声点值。每一层均得到一幅中间去噪图像,并继续进行噪声点的判决,最终得到完整的噪声点空间以及终极去噪图像。通过对多幅不同噪声比率的噪声图进行图像恢复的仿真实验验证后,得出结论:本文所提算法无论在低噪声比率还是高噪声比率的情况下均能有效地检测出图像中的随机值冲击噪声,漏检和误检像素数相对较低,同时获得了较好的图像去噪效果,极大地扩展了原算法的应用范围。
In this paper, an algorithm about random-valued impulse noise detection and removal based on the hierarchical filter technology is proposed. In order to solve the problem of severe miss detection of classical adaptive center-weighted median filter in the situation of high noise ratios, we set the noise judgment thresholds from high values to low values to select noisy pixels hierarchically. The impulse noise with different reliable degrees is selected through different thresholds and at the same time the detected pixel values are updated. The interim denoised image is generated in each denoising layer and the noise detection continues in the next denoising layer. Lastly, we get all the locations of noisy pixels and the final denoised image is obtained. Extensive experimental results for different noisy images with different noise ratios show that our proposed algorithm can obtain the good performance of random-valued impulse noise detection in the situations of not only low noise ratios but also high noise ratios. The miss and false noise detection ratios are both low relatively. At the same time, the good denoised images can be obtained. Our algorithm expands the application range of the classical adaptive center-weighted median filter.

摇摆结构及自复位结构研究综述
,吕西林
建筑结构学报 , 2011,
Abstract: 放松结构与基础间约束或构件间约束,使结构与基础或构件间接触面处仅有受压能力而无受拉能力,则结构在地震作用下发生摇摆,通过自重或预应力使结构复位,形成摇摆结构及自复位结构。已有研究表明,结构的摇摆降低了地震作用和结构本身的延性设计需求,减小了地震破坏,节约了结构造价。本文首先回顾了摇摆及自复位结构的发展历史,简要介绍了摇摆及自复位结构的基本原理,综述了摇摆桥墩、摇摆及自复位钢筋混凝土框架结构、摇摆及自复位钢框架结构、摇摆及自复位剪力墙结构、摇摆框架-核心筒结构等不同结构体系的发展现状,总结了摇摆及自复位结构发展趋势,并指出后张预应力和消能减震等多种技术的联合应用为摇摆及自复位结构的未来发展方向之一。
