SHUFFLING CARDS AND STOPPING TIMES.
From shuffling cards to walking around the building:An Inetroduction to modern markov chain theory。
Introduction The most common method of mixing cards is the ordinary riffle shuffle, in which a deck of n cards (often n = 52) is cut into two parts and the parts are riffled together. A sharp mathema...
A RULE OF THUMB FOR RIFFLE SHUFFLING     Deck  number  n  formula  asymptotic formula       2015/7/8
We study how many riffle shuffles are required to mix n cards if only certain features of the deck are of interest, e.g. suits disregarded or only the colors of interest. For a wide variety ...
Abstract: Many casinos routinely use mechanical card shuffling machines. We were asked to evaluate a new product, a shelf shuffler. This leads to new probability, new combinatorics, and to some practi...
We present a version of the domino shuffling algorithm (due to Elkies, Kuperberg, Larsen and Propp) which works on a different lattice: the hexagonal lattice superimposed on its dual graph. We use our...
We compare and contrast two types of deformations inspired by mixing applications -- one from the mixing of fluids (stretching and folding), the other from the mixing of granular matter (cutting and s...

介绍了一个简便的DNA改组操作程序.首先利用PCR扩增了两段具有高度序列同源性的1 700 bp左右的基因片段,两者相比较同源性大于93%.然后将其等量混合后,在Mg2+存在的条件下,用DNaseⅠ切割成10~50 bp的小片段.这些小片段在不外加引物的前提下,利用PCR反应进行重聚,再将重聚物经过两轮正常的PCR扩增,获得了与原来片段大小相当的基因片段.这一技术有利于从一组序列同源性程度...
