我从前在新加坡求学时的那位导师，他从前在日本求学时的导师Makoto
Nagao，曾任日本京都大学校长，算是日本计算机科学宗师级人物之一，
曾开创了机器翻译界影响深远的基于实例的机器翻译方法（Example-
based Machine Translation）。Makoto Nagao这名字的汉字写法是长
尾真，姓长尾，名真。
我这次在国内书店随便浏览时，远远一眼瞥到畅销书架上四个大字：
"长尾理论"，脑袋里第一反应是，莫非长尾真机器翻译理论被介绍到
国内来了？但是就算如此，好像也没理由放在畅销书这一块啊，这东
西只有计算语言学学术界感兴趣，怎么可能在普罗大众里畅销到这个
地步。然后才反应过来，这个"长尾理论"是Long Tail Theory的翻译
，跟长尾真没有半点关系。哑然失笑……
Long Tail这个长尾现象，说的是在一些情况下，概率密度图上一个顶
峰之后往下走的曲线拖出来的尾巴，虽然概率很低，但这条尾巴会很
长很长。比如ITunes这种网上音乐商店，卖出的歌曲销量最大的就那
么几十首，但也总有许许多多各种各样风格比较边缘、比较独特的曲
子，销量 |

For Q5, if they use CSF extract( a kind of Xenopus extract, which should be
natually mitotic extract, once you add Calcium, a good CSF extract will start
to cycle.), they can avoid the possible artifact. The problem is in their
paper they use all human proteins(separase, securin and cohesin.) If they use
CSF extract, the proteins they can analyze for MS are Xenopus proteins. What I
don't understand is why they use human proteins.
For Q6,
Nagao K, Yanagida M.
