Keyword search ads 没多少感觉，基本不反感。

这个interactive的iAd 有Display ads的意思，点进去就跟点其他iPhone APP一样。
试听效果是不错的。但问题是在玩几下，好奇心过去之后，有多少人矢志不渝地去看

suppose one standard deviation of R1=1
one standard deviation of V=1
case1 R2=a+b*1+c*1*1
benchmark case R2=a+b*1+c*1*0
the difference between case 1 and benchmark case will be Delta_R2=c*1*1
This is the effect of interaction term, right?

electroweak model which describes the weak interactions was built to be a
