Some Researches on Histones

The histone extracted from calf thymus glands is a complex system of proteins, which can be fractionated by chromatography on carboxymethyl cellulose columns into three principal fractions (1) very lysine-rich, (2) moderately lysine-rich, (3) arginine-rich. When examined by starch gel chromatography each of these gives more than one band. Methods have been devised for further separation of the ...

Researches on Ingeniously Behaving Agents

We have been studying the techniques for evolutionary robotics and experimenting with various robots applied evolutionary methods. We have paid special attentions to real robots and multi-agent problems with them. In this research domain, we named them as “Ingeniously Behaving Agents (IBA)”. This paper shows several techniques developed in our IBA laboratory and their experimental results appli...

Bells, Motels and Permutation Groups

This article is about the mathematics of ringing the changes. We describe the mathematics which arises from a real-world activity, that of ringing the changes on bells. We present Rankin’s solution of one of the famous old problems in the subject.
