简介:某些疾病被知道引起变化在物理并且房间的biomechanical性质。这些在其它之中包括癌症,疟疾,和镰刀房间贫血症。典型地,如此的物理性质变化能导致房间僵硬的几褶层增加或减少,它是重要的并且能导致严重病理和最终的灾难的故障身体功能。当有时开发了生物化学、生物的试金检测疾病的发作或存在,总是有需要开发更快速、精确、敏感的方法检测并且诊断疾病。Biomechanical性质变化能起一个重要作用在这方面。因此,对疾病biomechanics的研究不能仅仅给我们位于疾病前进下面的机制的深入的知识,但是能也为察觉和诊断用作一个强大的工具。这篇文章提供一些卓见进机会因为在疾病的发作或前进期间在细胞的机械性质换掉怎么重要,能为察觉和诊断作为有用工具被利用。我们将也展示已经被开发了执行如此的察觉和诊断的几种技术。

简介:这篇评论文章在基于分子的流动的一个新组的发展报导最近的进步诊断技术,包括分子的标注velocimetry(音乐电视)和分子的标注计温(MTT),为热地导致的流动结构的两质的流动可视化和流动速度和温度分布的量的整个地的大小。音乐电视和MTT技术能容易也被联合导致所谓的分子的标注velocimetry和计温(MTV&T)技术,它是在液体流动完成流动速度和温度分发的同时的大小的capble。而不是使用微小的粒子,分子的标注技术(音乐电视,MTT,和MTV&T)使用发磷光的分子,它能被适当波长的光子在刺激之上变成长持续的发光标记,作为为流动速度和温度大小的tracers。分子的标注技术的唯一的吸引力和实现被三个申请例子表明,它包括:(1)确定从激烈的柱体的不稳定的热转移过程到包围液体流动以便在在混合并且强迫的热传送对流政体操作的激烈的柱体后面在wake不稳定性上检验热效果,(2)处理揭示变化的不稳定的热转移和阶段的时间进化在内微尺寸,糖衣水微滴以便阐明对飞机糖衣现象恰当的内在的物理,并且(3)完成同时的微滴尺寸,v

简介:平行程序与不同线级的并行(TLP)由代码节的系列组成。作为结果,在一个平行程序的一个线程例如在CUDA程序的一个GPU内核,仍然包含顺序的代码和平行的环,是相当普通的。为了利用如此的平行,循环,最近的开普勒·恩威迪亚体系结构介绍动态并行,它允许一个GPU线程开始另一个GPU内核,从而减少从一个中央处理器运行内核的开销。与动态并行,然而,一个父母线程能仅仅通过全球存储器与它的孩子线程交流,运行GPU内核的开销甚至在GPU以内是重要的。在这份报纸,我们首先学习包含这些基准没有的平行的环,和热点的一套GPGPU基准一个很高的环计数或TLP的高度。因而,用动态并行利用如此的平行的环的好处也被限制抵消它的开销。我们然后介绍我们的建议答案在CUDA利用嵌套的并行,叫作CUDA-NP。与CUDA-NP,当一个GPU程序开始时,我们开始启用线程的一个高数字,并且使用控制流动为不同代码节激活线程的不同数字。我们用一条基于指令的编译器途径实现我们的建议CUDA-NP框架。为一个GPU核,一个应用程序开发者仅仅需要为可并行化的代码节增加象OpenMP一样编译指示。然后,我们的CUDA-NP编译器自动地产生优化GPU内核。它支持减小和扫描原语,探索不同方法散布平行的环重复进线程,并且高效地管理在薄片上资源。我们的实验证明为一套GPGPU基准,它已经被优化了并且包含嵌套的并行,我们的建议CUDA-NP框架进一步平均到多达6.69次和2.01次改进表演。
