来自主题: DataSciences版 - spark里aggregate的问题
刚看spark,被aggregate搞糊涂了。
我看的是这个网页的例子:
http://homepage.cs.latrobe.edu.au/zhe/ZhenHeSparkRDDAPIExamples
他的第一个例子,如果改成
val z = sc.parallelize(List(1,2,3,4,5), 2)
z.aggregate(0)(math.max(_, _), _ + _)
结果是7,这是怎么算的?为什么不是8或者9?
我看到这里的解答,http://blog.csdn.net/u010198460/article/details/38612649
如果z长度为6就平均分,否则呢?
还有两个很弱的问题:
1.这里的_是for each element in the RDD吗?z.aggregate(0)不算一个element吧,
那它对应的是后面两个下划线里的第一个吗?
2.这个z.aggregate(0)(math.max(_,_),_+_)用python写来是怎样的?我对这个_还是不
解。
谢谢各位!

在Reserves deposited with lender一栏里,收了三个月的home insurance总共 X,然
后又收了六个月的county property tax 总共是 Y,最后有一项aggregate adjustment
是 Z
这三项 X+Y-Z = W,W是initial deposit for escrow account。我以为已经帮我把六
个月的property tax给交了呢,打电话去问了说没交,说我escrow balance就只有W,
是扣掉aggregate adjustment之后的钱
这个aggregate adjustment是什么?

Escrow account里面存入的tax和insurance reserve是为了下个payment due准备的。
以加州的tax为例,如果loan是9月份close的,那么9月份收的六个月的tax reserve是
为了让银行有钱给你交12月份的那个tax due。你大概11月份去check一下就会发现税被
交掉了。其它州以此类推。
至于aggregate adjustment,这一项的数学意义在于使得X+Y-Z得到的“W”这个值在一
整年以后是完全和现在的“W"值一样。还是拿加州举例来说,9月份close,假设W值为
6000,X为360,Y为5200,那么Z(aggregate adjustment)就是440;一年以后,银行会
帮你付掉2个tax due和一个insurance premium due,这个时候你再看escrow account
里面剩的balance一定是等于W的。所以说,这个Z(aggregate adjustment)从W,X, Y
反推回来的。一般是几十到几百不等。当然,这里有个前提是home insurance premium
和tax paym... 阅读全帖

来自主题: Biology版 - EMSA遇aggregate--衰人再问
前段时间来求救,做EMSA,连作为negative control的library都bind的一塌糊涂:
http://www.mitbbs.com/article0/Biology/31394721_0.html
得到了大家的很多宝贵建议。综合考虑后觉得自己的protein是形成了aggregate,拖了
n久总算确认
了——见附件图。gel 是4% native PAGE,silver stain,lane 1/2/4是target
protein,
3/5是control(5是homolog,如果没aggregate的话target也该在那个position)。其
中lane
2/4加了0.1%/1%的triton,没区别。另外也试了DTT,也不行。真衰呀。。。
这个target是我side project必须要用的,而且要用大量。好不容易找到家便宜的,还
这么背。。
。还有什么方法可以搞掉这个aggregate吗?更狠的detergent??请指教!//bow

Which statement about the sample code above is correct?
a) It is an aggregate, but not a POD (Plain Old Datatype).
b) It is just a POD.
c) It is both a POD and an aggregate.
d) It cannot be initialized because there are no constructors.
e) It cannot be initialized as an array element because there is no default

刚刚做了一个 Daily Deal Aggregation 的网站,是我自己做的(没日没夜的干了好几天了)。
http://pal-likes.com/
现在有很多 Local Daily Deals 网站,例如 GroupOn, LivingSocial, Tipper 等等。如果把这些网站上的 Deal 都爬到一起,这样在一个地方就可以看到当地所有的 Daily Deals 了。
现在已经爬了几十个 source (不过每个城市都不一样)。网站功能还在继续开发,如果有什么问题,可以随时告诉我,谢谢乐!

来自主题: Programming版 - aggregation vs. compostion. vs. association
从你的解释,我能不能理解成:
assication A 用到了 B ?比如函数里的参数是B?
aggregation B 作为 A的一部分但是,A死了,B还活 (A里边放B reference,pointer
,但是不delete B)?
composition -- A 决定 B生死(A里有B实体,B reference,或者pointer,而且负责
delete B)?
红猪侠给看看对吗?

装了graphivz, 勾选了dot选项,
但是产生的 class hierarchy 只有“继承关系”,没有Aggregation关系。
比如
Class A{

class B{
private:
A* ptrA;

产生的图,没有显示A,和B的关系。
还有,产生的class hierarchy图只有 public functions, 没有private data.
请问,怎么设置才能显示 private part of a class,
还有显示 aggegation关系

来自主题: Biology版 - EMSA遇aggregate--衰人再问
如果你的蛋白已经aggregate了,加1mM的DTT还原能力不够的。1mM的话,一般只能起防
止二硫键生成的效果。用来打开已经形成的二硫键的话,你加到5mM甚至10mM再试试,
incubate个半小时到一小时的样子再跑胶。
另外,你的蛋白跑SDS胶是纯的么?
还有就是你的蛋白上样量明显太多了,少加一点。
还还有,上回你问的那个Reverse transcription的efficiency的问题,我帮你问过了
,他们都不做测试的,估计反正library够大。。。

在细胞质中
难道人家用了specific的染色方法 看到了蛋白聚集?

楼主确实犯了一些严重错误。
先简要介绍一下燃烧知识,碳氢化和物不完全燃烧产物包含千百种不同成分。不论是烧
甲烷为主的天然气,还是以C8H18为主的汽油,还是C12H26为主的柴油,产生的成分都
是一样的,不同的只是各个成分的浓度。如果是富油燃烧,很容易形成碳颗粒(soot)
。碳颗粒刚形成的precursor particle大小只有2-3纳米,分子量大致为2000-5000之间
,然后迅速通过表面反应形成20-40纳米大小的颗粒(期间dehydrogenation过程导致碳
原子和氢原子比例达到9:1左右,基本上成为吸收光线最有效的blackbody黑体),分子
量达到100万左右。在这个过程中碳颗粒之间通过碰撞agglomeration过程形成类似
fractal的aggregate,这种aggregate大小由具体燃油化学反应时间,包括氧化时间长
短决定,包含从几十个到几万个颗粒,由于是三维结构fractacal dimension 只有1.8

Protein precipitation is basically the removal of proteins from solution.
This can be achieved in many ways including the addition salt, which takes
away the water molecules surrounding proteins in solution (as the salt
concentration increases, more water molecules associate with the salt ions
