生物医学大数据 Case study 由Human genome project提出之后,提出的精准医学.它的初衷是将数据standard后easy应用,我国重要重在疾病预警和疗效评价. 在疾病预警上的案例包括新生儿筛查和致癌基因检测,安杰利娜朱莉做了一个乳腺癌早期诊断并去除风险的推动者.但是因为早期诊断依然有很高的假阳性率,所以做出切除的判断还是存在很大风险的(不做怕是真的,做了怕是假的).其假阳性率高的原因之一是突变不一定有表型,所以应对方法是reduced penetrance.孟德尔遗传…

RISC机的例子 David A. Patterson 加州大学伯克利分校计算机科学系 David R. Ditzel 贝尔实验室计算科学研究中心 介绍 计算机体系结构最主要的目标之一就是设计比之前产品具有更高成本效益的计算机.成本效益包括用于制造计算机的硬件成本.软件花费.在初始硬件和随后程序调试及测试所需的费用.如果我们回顾计算机家族的过往历史,我们会发现最常见的体系结构的变化倾向于朝向更复杂的机器.假设这一额外的复杂性对于新型产品的成本效益产生积极的平衡作用.在这篇论文中我们认为这一趋势并…
