摘要：Born of the America of 1960s, performance art comes along as a celebration of presentation rather than re-presentation, as a display form of art, and an art form that does not admit of duplication. This paper presents a reading of the seductive power of performance art as rooted in our theatrical nature. I will address performance art as an emancipated form of the theatrical, where by ＂theatrical＂ I mean a specific mode of presentation and a specific mode of perception： the mode of presentation of the self to the social and the mode of perception of the self through the social. Performance art, I will argue, is hardly an anomaly of our time. Rather, its source of disturbance and fascination lies in the natural, though excessive manifestation of our theatrical nature. By its appeal to the shocking, the perilous, or the mundane even, this form of art confirms what Paul Woodruff has addressed as ＂the necessity of watching and being watched.＂ Performance art shows us the danger of self-presentation, the recognition of the other gaze as the self＇s greatest need and greatest fear. It needs no words. Mere action is more seductive than speech and does not accept speech in return. Once it has been performed, it is no longer. In Nietzsche＇s words, it celebrates the fleeting moment＇s ＂greatest weight.＂ As Samuel Beckett used to tell his actors, performance artists seem to tell their spectators： ＂Go on failing. Go on. Only next time, try to fail better.＂

摘要：This paper presents a novel self localization method using parallel projection model for mobile sensor in navigation applications. The algorithm estimates the coordinate and the orientation of mobile sensor using projected references on visual image. The proposed method considers the lens non-linearity of the camera and compensates the distortion by using a calibration table. The method determines the coordinates and orientations with iterative process, which is very accurate with low computational demand. We identify various sources of error on the coordinate and orientation estimations, and present both static sensitivity analysis of the algorithm and dynamic behavior of the mobile sensor. The algorithm can be utilized in mobile robot navigation as well as positioning application where accurate self localization is necessary.

摘要：Since the publication of Coraz6n tan blanco （A Heart so White） （1992）, many critics have compared the Spanish novelist Javier Marias to Marcel Proust. Both favor long, meandering sentences, in which they insert voluminous asides. In thematic terms, their narratives are constantly involved with meditation over the extent to which we can understand the past, or the degree to which we can know either ourselves or others. Beyond their common preoccupation with time and memory, I will consider some remarkable similarities between Marias＇ and Proust＇s formative years and the role translation played in the development of their style. I will show the many ways in which Proust ＂haunts＂ Marias： in his metaphorical use of the translating practice, in his love of deferral, and in his brooding first-person narrators, racked by the anxiety of ignorance.

摘要：Ankylosing spondylitis(AS) is a chronic inflammatory disease that affects 1% of the general population. As one of the most severe types of spondyloarthropathy, AS affects the spinal vertebrae and sacroiliac joints, causing debilitating pain and loss of mobility. The goal of this review is to provide an overview of AS, from the pathophysiological changes that occur as the disease progresses, to genetic factors that are involved with its onset. Considering the high prevalence in the population, and the debilitating life changes that occur as a result of the disease, a strong emphasis is placed on the diagnostic imaging methods that are used to detect this condition, as well as several treatment methods that could improve the health of individuals diagnosed with AS.

摘要：目的 :介绍作者所在的实验中心近年来对于黄斑区和近周边视网膜区 (≤ 8°)模糊认知感的研究结果。方法和结果 :先后介绍三个实验。实验一测量了近周边视网膜区的焦深 (即对视网膜离焦的主觉耐受程度 ) ,并将其与黄斑区的反应进行了比较。实验二测量了近周边视网膜区的模糊敏感阈值和模糊辨别阈值。上述两实验结果表明 ,人眼焦深在近周边视网膜区随其与黄斑的距离增大而逐渐升高 ,其值从黄斑区的 0 .89D增加到距黄斑 8度视角离心区的 3.51D。模糊敏感阈值 ,即导致初始模糊认知感的视网膜离焦度 ,也随其与黄斑的距离增大而逐渐升高 ;其值从黄斑区的 0 .85D增加到距黄斑 8度视角离心区的 1 .89D。模糊辨别阈值 ,即在初始模糊认知感的条件下觉察初始模糊程度改变的视网膜离焦度 ,同样亦随其与黄斑的距离增大而逐渐升高 ,其值从黄斑区的 0 .4 5D增加到距黄斑 8度视角离心区的 0 .93D。基于实验一 ,二的结果 ,作者设计了实验三 :通过测量视标大小对焦深的影响以研究近周边视网膜区和黄斑区对模糊认知感的综合效应。结果表明 ,人眼焦深在近周边视网膜区随着视标尺寸的增大而逐渐升高 ,且据其数据分析结果及回归方程斜率的个体差异性 ,可将总体实验对象区分为两个亚组 :即“黄斑主导型”和“黄斑
