Exact correspondence between walk in nucleotide and protein sequence spaces

Exact correspondence between walk in nucleotide and protein sequence spaces

In the course of evolution, genes traverse the nucleotide sequence space, which translates to a trajectory of changes in the protein sequence in protein sequence space. The correspondence between regions of the nucleotide and protein sequence spaces is understood in general but not in detail. One of the unexplored questions is how many sequences a protein can reach with a certain number of nucl...

Quasi-Exact Sequence and Finitely Presented Modules

The notion of quasi-exact sequence of modules was introduced by B. Davvaz and coauthors in 1999 as a generalization of the notion of exact sequence. In this paper we investigate further this notion. In particular, some interesting results concerning this concept and torsion functor are given.

Exact correspondence between Renyi entropy flows and physical flows

We present a universal relation between the flow of a Renyi entropy and the full counting statistics of energy transfers. We prove the exact relation for a flow to a system in thermal equilibrium that is weakly coupled to an arbitrary time-dependent and nonequilibrium system. The exact correspondence, given by this relation, provides a simple protocol to quantify the flows of Shannon and Renyi ...

Exploration of the correspondence between visual and acoustic parameter spaces

This paper describes an approach to match visual and acoustic parameters to produce an animated musical expression. Music may be generated to correspond to animation, as described here; imagery may be created to correspond to music; or both may be developed simultaneously. This approach is intended to provide new tools to facilitate both collaboration between visual artists and musicians and ex...
