One modified method of characteristics used to analyze the multiconductor transmission lines

1.INTRODUCTIONThe analysis of electromagnetic compatibility becomesmorei mportant in the analysis of the multiconductortransmissionlines(MTLs).It provides the effectivemethod for designing the MTLs.Several methodsbased on frequency domain and ti me domain tech-niques have beenrecently proposed[1,2].Thefrequen-cy method should performthe inverse Fourier trans-formation,so it is not more accurate than ti memethod to some degree.The method of characteris-ticsis based ontheti me domain met…

Osteoclast-poor human osteopetrosis due to mutations in the gene encoding RANKL

Autosomal recessive osteopetrosis is usually associated with normal or elevated numbers of nonfunctional osteoclasts. Here we report mutations in the gene encoding RANKL (receptor activator of nuclear factor-KB ligand) in six individuals with autosomal recessive osteopetrosis whose bone biopsy specimens lacked osteoclasts. These individuals did not show any obvious defects in immunological parameters and could not be cured by hematopoietic stem cell transplantation; however, exogenous RANKL induced formation of functional osteoclasts from their monocytes, suggesting that they could, theoretically, benefit from exogenous RANKL administration.     

The neuronal sortilin-related receptor SORL1 is genetically associated with Alzheimer disease

The recycling of the amyloid precursor protein (APP) from the cell surface via the endocytic pathways plays a key role in the generation of amyloid beta peptide (Abeta) in Alzheimer disease. We report here that inherited variants in the SORL1 neuronal sorting receptor are associated with late-onset Alzheimer disease. These variants, which occur in at least two different clusters of intronic sequences within the SORL1 gene (also known as LR11 or SORLA) may regulate tissue-specific expression of SORL1. We also show that SORL1 directs trafficking of APP into recycling pathways and that when SORL1 is underexpressed, APP is sorted into Abeta-generating compartments. These data suggest that inherited or acquired changes in SORL1 expression or function are mechanistically involved in causing Alzheimer disease.     

衰竭性运动后的最大通气量

在剧烈运动中,通气肌是否出现疲劳和机能能力下降,这是有争论的。Fregosi 等报道过在衰竭性赛跑运动中,鼠的膈肌中乳酸急剧增加。Bye 等也指出在进行高强度短时间的运动之后,膈肌的最大跨壁压力降低。是这些变化还是其它的变化致使剧烈运动中和运动后最大通气能力减弱,目前尚未清楚。在本研究中,我们企图通过测定在跑台上进行持续时间为3—10分钟或60分钟的衰竭性运动的最后几分钟和运动后的60秒随意最大通气量,来探查这     

用测量模态阻尼和振型的方法对复合材料薄平板进行无损质量检测

复合材料薄平板经热压制成后,都需要进行质量检测。本文探索用测量模态阻尼和振型的方法,对复合材料薄平板的制作质量进行无损检测,作为对其它昂贵的无损检测方法的补充。略述用振动方法进行无损检测的原理,测量薄平板阻尼的方法以及提高测量精度的措施。还讨论在测量薄平板阻尼时可能遇到的一些特殊问题(如非线性刚度、拍、模态密集等问题);以云母基复合材料薄平板作为例子,从测量其阻尼和振型的结果,对这种板的制作质量进行讨论。
