Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.

井下各向异性地层中的挠曲波

油气藏评价与开发 1995年第2期 78-78页

作者： bikash K.Sinha

摄动法是分析沿井中各向异性地层传播的弹性波的有效方法之一。应用摄动模型可以计算各向异性目的层与未摄动的各向同性参考层间弹性常数差异引起的波散曲线的变化。参考地层的等价各向同性常数根据与选择挠曲波的传播方向和偏振方向对... 详细信息

摄动法是分析沿井中各向异性地层传播的弹性波的有效方法之一。应用摄动模型可以计算各向异性目的层与未摄动的各向同性参考层间弹性常数差异引起的波散曲线的变化。参考地层的等价各向同性常数根据与选择挠曲波的传播方向和偏振方向对应的恰当的纵、横波速度求取。未摄动解的选择原则是使

探头压力对浅表动脉血流超声检测结果的影响

东南大学学报（医学版） 2013年第4期32卷 421-424页

作者：高启张炽敏王玲胡中倩毕卡东南大学附属中大医院超声诊断科江苏南京210009

目的:探讨应用彩色多普勒超声检查浅表动脉时,探头施加压力的大小对血流动力学参数检测结果的影响。方法:选取20名健康志愿者(21～30岁),测量中指指掌侧固有动脉40支,在探头外加压力分别为0、200、400 g时测量收缩期峰值流速(PSV)、舒... 详细信息

目的:探讨应用彩色多普勒超声检查浅表动脉时,探头施加压力的大小对血流动力学参数检测结果的影响。方法:选取20名健康志愿者(21～30岁),测量中指指掌侧固有动脉40支,在探头外加压力分别为0、200、400 g时测量收缩期峰值流速(PSV)、舒张末期流速(EDV)、平均血流速度(TAMAX)、血流阻力指数(RI)及搏动指数(PI)。对不同压力组的测量数据进行组间统计学比较。结果:PSV、EDV、TAMAX随着探头压力的增加呈逐渐递减趋势,而PI、RI呈递增趋势。结论:血流动力学参数作为超声评价浅表血管结构与功能的重要指标,在检测时明显受到检查者对探头施加压力大小的影响,在对超声检测结果进行分析时不应忽略这一因素的影响。
