摘要：The paper presents the Quasi Newton model of Artificial Neural Network for design of circular microstrip antenna (MSA). In this model, a closed form expression is used for accurate determination of the resonant frequency of circular microstrip patch antenna. The calculated resonant frequency results are in good agreement with the experimental results reported elsewhere. The results show better agreement with the trained and tested data of ANN models. The results are verified by the experimental results to produce accurate ANN models. This presents ANN model practically as an alternative method to the detailed electromagnetic design of circular microstrip antenna.

摘要：RNAs of different shapes and sizes,natural or synthetic,can regulate gene expression in prokaryotes and *** RNAs have recently appeared to be more widespread than previously thought,but their role in prokaryotes remains ***,by inserting a riboregulatory sequence within a group I permuted intron-exon ribozyme,we created a small noncoding RNA that self-splices to produce a circular riboregulator in Escherichia *** showed that the resulting riboregulator can trans-activate gene expression by interacting with a cis-repressed messenger *** characterized the system with a fluorescent reporter and with an antibiotic resistance marker,and we modeled this novel posttranscriptional *** first reported example of a circular RNA regulating gene expression in *** adds to an increasing repertoire of RNA synthetic biology parts,and it highlights that topological molecules can play a role in the case of prokaryotic regulation.

摘要：The 2014 Nobel Prize winner in literature,Patrick Modiano,in his masterpiece,In the Caféof Lost Youth,describes the story of Louki,a young mysterious lady who has been making time-travelling diaspora in all her *** thesis makes deep analysis by making use of temporal relationship—the fragmentation of the past,the hopeless pursuit from the present to the future,and the confusion of time,revealing that the essence of life is the intertwining of reality and illusion,the confusion of pain and happiness,the ambiguity of survival and ***,it also argues that,the story of the heroine Louki,who,like most other human beings,is living like“drifting duckweed and floating clouds”within the global circular diaspora with time as the center.

摘要：The 2012 Nobel Prize winner in Literature,Chinese writer Mo Yan,describes the 50 years history of Chinese countryside from 1950 to 2000 in his masterpiece Life and Death Are Wearing Me *** the six artistic images of the innocent killing landlord’s reincarnation as a donkey,an ox,a pig,a dog,a monkey,and a big head baby boy,it focuses on the topic of the *** explains that all the relationships between the peasants and the land,and shows the changes in the life of Chinese peasants and their tenacious,optimistic and tough spirit since the foundation of the New *** analyzing the unique plot of the six great divisions in the wheel of karma and the hero’s mental journey,it can be found that the theme of the novel is to reveal a global circular diaspora with the moon,rather than the sun as the center of the circle,which is quite different from the real world.

摘要：胶原是广泛研究和应用的生物材料,具有独特的三螺旋结构,此结构与其生物学性能密切相关。以胶原模拟多肽(collagen mimetic peptide,CMP)作为胶原的模型分子,通过圆二色谱研究了CMP的三螺旋结构、热稳定性等随序列或长度的改变所发生的规律性变化。根据形成胶原三螺旋结构的重复序列(POG)_n及胶原上α_2β_1整合素识别位点序列GFOGER设计五种不同序列或长度的CMP,采用圆二色谱表征了CMP的三螺旋结构,并通过检测CMP的程序升温变性和程序降温复性过程中圆二色谱的变化,研究了CMP三螺旋结构的热变性过程、解链温度以及复性过程。实验结果显示,五种CMP室温下均以三螺旋结构的形式存在,CMP三螺旋结构的热稳定性随POG的个数增加而增强;不同于胶原,CMP三螺旋结构的热变性是可逆的,升温过程中三螺旋解聚(变性),降温过程又可重新组装(复性),复性过程有明显的'磁滞'现象。研究结果可为进一步研究胶原与CMP分子特征性的三螺旋结构形成规律以及基于CMP的人工类胶原生物材料的研究提供依据。

摘要：业主：Benetton Group spa地点：意大利特雷维索设计：2006年施工：2007年合作：Jesús Donaire面积：1868 m2向天空开放的箱式建筑我们建造了一座由九个小正方形组成的方形箱式建筑。中心的方形用于采集来自前厅高处的光线。教室设置于四周的方形体块中。该方形结构被一道较大的圆形双围墙包围。建筑设有四个露天庭院,分别代表四大元素： 空气、土、火、水。围墙之间的空间可用作儿童的＂秘密＂游戏场所。庭院空间在弯曲的墙体之间张弛有致，效果尤为出色。

摘要：我们仿效BBC的广播节目“60秒改进世界”（Sixty Second Idea to Improve the World）推出了“改进建筑60秒”栏目,每期将在世界范围内采访两位人物,请他们就建筑、城市,景观、技术等相关问题在60秒的时间里讲出一个或两个有启发性,批判性甚至有争议性的观点。本栏目如实记录了他们的话,
