Correlation matrix for quartet codon usage
L. Frappat, A. Sciarrino, P. Sorba
It has been argued that the sum of usage probabilities for codons, belonging to quartets, that have as third nucleotide C or A, is independent of the biological species for vertebr…
A minimum principle in mRNA editing ?
L. Frappat, A. Sciarrino, P. Sorba
mRNA editing of sequences of many species is analyzed. The nature of the inserted nucleotides and the position of the insertion sites, once fixed the edited peptide chain, are expl…
Theoretical prevision of physical chemical properties of amino acids from genetic code
L. Frappat, A. Sciarrino, P. Sorba
Using the crystal basis model of the genetic code, a set of relations between the physical-chemical properties of the amino acids are derived and compared with the experimental dat…
Crystalizing the genetic code
L. Frappat, A. Sciarrino, P. Sorba
New developments are presented in the framework of the model introduced by the authors in refs. [1,2] and in which nucleotides as well as codons are classified in crystal bases of…
Integrable Chain Model with Additional Staggered Model Parameter
D. Arnaudon, R. Poghossian, A. Sedrakyan +1
The generalization of the Yang-Baxter equations (YBE) in the presence of Z_2 grading along both chain and time directions is presented. The XXZ model with staggered disposition alo…
A remarkable connection between Yangians and finite W-algebras
E. Ragoucy, P. Sorba
For a large class of finite W algebras, the defining relations of a Yangian are proved to be satisfied. Therefore such finite W algebras appear as realisations of Yangians. This re…
