Just wondering if there is a way to quantify a specific gene expression in
mixed population of cells.
For example:
Each sample has x number of cells from normal tissue mixed with y number of
cancer cells. x and y are unknown.
How to compare some specific gene expression profiles (those genes only
expressed in cancer cells) among different
samples.
Any reference?

4. Do HYP discriminate against Asian-Americans?
To address the question of whether HYP discriminate against Asian-Americans,
it is instructive to review the Department of Education Office of Civil
Rights’ (OCR) findings from its investigation into this matter. In 1990,
OCR concluded that Harvard did not discriminate against Asian-Americans on
the basis of race but rather that Asians were disadvantaged by Harvard’s
admissions preferences for legacies (children of alumni) and recruited

商业信息 can still mean a lot of things, some that can be quantified
(numeric data), and some that cannot be quantified (competitor's
marketing and sales strategies, product development plans, etc.).
If the 商业信息 is quantifiable, you can question its accuracy and
I suppose its reliability (the data that you have may be accurate,
but incomplete in a broader context, and therefore maybe unreliable).
If the 商业信息 is not quantifiable, I think you would only question
its reliability. It sound a bit stran

这玩意儿要 quantify。。。我在旁边帖子线程里写了,我这里重复一遍就是:
查一下 2017 年 qualify 并自愿参加 AIME 和 AIME-II 的男女人头数。
我查了一下,总共 606 个女生,3223 个男生,不男不女的就算了不统计了。
这样男女比例差不多是 5:1 。
狗歌 interview 总不能难度牛掰到比 AIME qualifiers 更狠吧。
这么算下来,如果狗歌里混滋马工男女比例在 5:1 附近,那可以赖在不管是天性还是

但如果狗歌混滋马工男女比例是 20:1,那至少总得给个 20:1 的理由不是?

Wholesale to Store == Wholesale to Warehouse.

B&M could argue that when people buy from us, they pay gas while when they

来自主题: Swimming版 - TI转体和重心前移怎样提供动力
根据saja科普的TI理论,做分析如下。saja看看能不能给terry老爷子下一版TI教程投
稿。
速度波峰之所以成为速度波峰,因为驱动效果最好的划水+打水刚刚完成。假设速度波
峰是2,速度波谷是1;那么速度波峰时刻的阻力是4,速度波谷时刻的阻力是1。根据前
面的讨论,达到速度波峰之后一只手在水里不许动(另一只在空中),脚不许动(一个
周期一侧只有一次打水机会,这一侧的打水刚刚做完),只有身体可以继续转(根据TI
的大幅度转身理论)并且重心可以前移。直觉上这种继续转体+重心前移增加的些许动
力,不足以对抗阻力4,但是也许和阻力1差不多。就算对抗不了1,那么随着前进速度
的继续下降,总会达到某一个平衡点,比如波谷速度0.5,阻力0.25。
如果这种分析基本正确,那么就意味着:
A: 一旦进入速度下降阶段,先不要着急过猛地转体和引导重心向下,因为这个时候速
度可能是1.5,1.25,阻力仍然很大,把力气用在这个pre-速度波谷阶段仍然不合算。等
到速度下降到1,再开始转体,等速度达到0.75,转体力量达到最大。
B: 增加继续转体和引导重心前移的动力是关键。这里有必要搞清楚这两个动作是如何... 阅读全帖

前两天那个DC的security robot真的是自杀而溺水的吗?
还有前几年盛传的那个奥地利的Roomba自动吸尘器打开炉子自焚自杀,是真的假的?
刚读了那个《未来简史》的作者、以色列年轻历史教授赫拉利月初在北京做的演讲《人
类将会失去这些力量》,描述人工智能可能怎样逐步取代人类、大部分人将失业、少数
拥有机器人的精英阶层没有动力投资弱势群体、社会分化成为最大危险、现在的孩子该
学什么等等。我还连读带比划地念给小孩听了,很容易懂,又很贴近他们的生活(
Amazon, Youtube,Kindle, 手机……)。他们听完说:Scary... 不过这篇演讲断言,
机器人是没有意识和情感的,也没有任何证据或迹象表明将来会有。然后历史教授表达
了对没有意识和情感的机器人控制世界的担心,呼吁人们开发人工智能时严密考虑对社
会、经济、政治带来的影响。
机器人肯定不会有意识和情感——各位同意吗?有关机器人自杀的新闻都是讹... 阅读全帖
