Technologies associated with cardiac resynchronization therapy (CRT) devices and lead systems have progressed.However, dislocation after coronary sinus (CS) lea
The torsional static and dynamic behaviors of circular nanosolids such as nanoshafts,nanorods and nanotubes are established based on a new nonlocal elastic stre
Applying the multidimensional Lindstedt-Poincaré (MDLP) method,we study the forced vibrations with internal resonance of a clamped-clamped pipe conveying fluid
Semantic-based searching in peer-to-peer (P2P) networks has drawn significant attention recently.A number of semantic searching schemes,such as GES proposed by
6月6日至7日,第10届中国兔肉节暨河南省首届兔业交易会在鹤壁市淇县召开。大会以“倡导绿色健康兔肉消费,促进兔业健康可持续发展”为主题,大力弘扬中国传统兔文化,展示兔业企业
在200℃温度下进行了700h双层铜互连(M1/M2)的应力迁移加速老化试验,结合有限元分析和聚焦离子束(focused-ion-beam,简称FIB)技术研究了通孔直径分别为500和350nm的铜互连应
改进了单分子横向磁镊装置,可以直接用于观察单个DNA分子的伸长和扭转并随时更换样品池内的溶液,还可以同时操纵多个DNA分子,大大提高实验效率.此方法可以提供0.1到40pN范围
首先采用改进的 k 均值无监督图像分割算法将图像分割成不同的区域,提出信息瓶颈聚类方法对分割后的区域进行聚类,建立图像语义概念和聚类区域之间的相互关系.然后对未标注的图像进行分割,在给出分割区域的条件下,计算每个语义概念的条件概率,使用条件概率最大的语义关键字实现图像语义的自动标注.对一个包含500幅图像的图像库进行实验,结果表明,本文方法比其它方法更有效.
背景:近年来,与骨肉瘤耐药相关的基因研究大多局限于单个基因或单个通路.而进行细胞凋亡和细胞周期调控双通道同时阻断有可能逆转药物耐受机制.目的:构建bcl-2和cyclin D1特
