We describe a family of representations in SL(3, $$\mathbb {C}$$ C ) of the fundamental group $$\pi $$ π of the Whitehead link complement. These representations are obtained by considering pairs of regular order three elements in SL(3, $$\mathbb {C}$$ C ) and can be seen as factoring through a quotient of $$\pi $$ π defined by a certain exceptional Dehn surgery on the Whitehead...
There is a need for rules allowing three-dimensional structure information to be derived from protein sequences. In this work, consideration of an elementary protein folding step allows protein sub-sequences which optimize folding to be derived for any given protein sequence. Classical mechanics applied to this system and the energy conservation law during the elementary folding step yields an equation...
Why is the genetic code the way it is? Concepts from fields as diverse as molecular evolution, classical chemistry, biochemistry and metabolism have been used to define selection pressures most likely to be involved in the shaping of the genetic code.Here minimization of kinetic energy disturbances during protein evolution by mutation allows an optimization of the genetic code to be highlighted. The...
