Bisecting N-acetylglucosamine(GlcNAc),a GlcNAc linked to the coreβ-mannose residue via aβ1,4 linkage,is a special type of N-glycosylation that has been reported to be involved in various biological processes,such as cell adhesion and fetal *** N-glycan structure is abundant in human trophoblasts,which is postulated to be resistant to natural killer cellmediated cytotoxicity,enabling a mother to nourish a fetus without *** this study,we hypothesized that the human amniotic membrane,which serves as the last barrier for the fetus,may also express bisected-type *** test this hypothesis,glycomic analysis of the human amniotic membrane was performed,and bisected N-glycans were ***,our proteomic data,which have been previously employed to explore human missing proteins,were analyzed and the presence of bisecting GlcNAc-modified peptides was confirmed.A total of 41glycoproteins with 43 glycopeptides were found to possess a bisecting GlcNAc,and 25 of these glycoproteins were reported to exhibit this type of modification for the first *** results provide insights into the potential roles of bisecting GlcNAc modification in the human amniotic membrane,and can be beneficial to functional studies on glycoproteins with bisecting GlcNAc modifications and functional studies on immune suppression in human placenta.

作者： feng guan-hong XU Tian-fu ZHU Hui-xing Key Laboratory of Groundwater Resources and Environment Ministry of Education Jilin University

CO_2 is now considered as a novel heat transmission fluid to extract geothermal energy. It can be used for both energy exploitation and CO_2 geological sequestration. Here, a 3-D, "two-spot" pattern well model is developed to analyze the mechanism of CO_2-water displacement and heat extraction. To obtain a deeper understanding of CO_2-geothermal system under some more realistic conditions, heterogeneity of reservoir's hydrological properties is taken into account. Due to the fortissimo mobility of CO_2, as long as the existence of highly permeable zone between the two wells, it is more likely to flow through the highly permeable zone to reach the production well, even though the flow path is longer. The preferential flow shortens circulation time and reduces heat-exchange area, probably leading to early thermal breakthrough, which makes the production fluid temperature decrease rapidly. The analyses of flow dynamics of CO_2-water fluid and heat may be useful for future design of a CO_2-based geothermal development system.

In order to meet the requirements of indoor illumination, a LED daylight lamp model was designed, it can replace traditional fluorescent lamp without insteading additional power supply establishment. The optical properties of the model were simulated using optical analysis software. Its luminous efficiency is about 30.4 lm/W, and the illuminance is about 38 lux when the distance is 1.5 m between the center of the model and measured spot. With the theoretically-optimized design of LED model, experiments based on the results of the optimal simulation in the laboratory were conducted to verify the performance of the proposed LED model, it reaches a power factor of about 0.8 at 6 W. The simulation results are very similar with the measured values. It is testified that simulative method is one of the effective tools for LED lighting optical design.

通过分析IEEE 802.16关于VoIP(voice over IP)的传输规范和服务质量保证机制,指出了区分VoIP的优先级和VoIP要求弹性QoS的性质对VoIP接纳控制有着极其重要的意义,提出了VoIP接纳控制的弹性准则和优先级准则。在运用有效带宽理论确定了VoIP传输所需最小带宽的基础上,提出了基于优先级的弹性接纳控制算法,并以概率强度因子对算法进行了优化。该算法能够根据剩余资源动态地调整接纳强度和策略,对不同优先级的VoIP表现出不同的接纳特性,资源紧张时合理限制低优先级VoIP的接纳。为评价算法性能,通过Markov模型对建议算法的拒绝率进行分析,并在PMP(point-to-multipoint)模式下与新呼叫限制算法进行了对比仿真,结果表明本算法在表现出更高接纳能力的同时具有更低的新连接阻塞率和切换连接掉线率。

复仇是新文学的一大母题。近现代中国贫弱和耻辱的灰色境遇激发了以家国为己任的知识分子悲壮和忧愤的民族自觉,复仇成了消解焦虑的文化革命想象。鲁迅《铸剑》的重心和巧妙在于复仇过程和复仇方式上的设计,"后复仇"情节成了复仇之上的复仇。巴金是在复仇的沉思中完成了思想和启蒙的另一种文学选择。汪曾祺复仇者为父报仇的永恒模式成了心灵扭曲和罪恶的象征。曹禺借复仇书写生命的原始强力,同时也写了人的现代困境。茅盾《参孙的复仇》的意义是多重的,除复仇的多向外,还有对女性和自己的复仇。近现代中国"被侮辱与被损害"的集体记忆使得复仇成为讲述中国故事的便捷途径。
