Co-expression of statistically over-represented peptides in proteomes: a key to phylogeny ?
Luca Ferraro, Andrea Giansanti, Giovanni Giuliano +1
It is proposed that the co-expression of statistically significant motifs among the sequences of a proteome is a phylogenetic trait. From the co-expression matrix of such motifs in…
Universal behavior in the static and dynamic properties of the -XY model
Andrea Giansanti, Daniele Moroni, Alessandro Campa
The -XY model generalizes, through the introduction of a power-law decaying potential, a well studied mean-field hamiltonian model with attractive long-range interactions. In th…
Percolation and lack of self-averaging in a frustrated evolutionary model
Andrea De Martino, Andrea Giansanti
We present a stochastic evolutionary model obtained through a perturbation of Kauffman's maximally rugged model, which is recovered as a special case. Our main results are: (i) exi…
Critical percolation and lack of self-averaging in disordered models
Andrea De Martino, Andrea Giansanti
Lack of self-averaging originates in many disordered models from a fragmentation of the phase space where the sizes of the fragments remain sample-dependent in the thermodynamic li…
First experimental tests of the Peyrard-Bishop model applied to the melting of very short DNAs
Alessandro Campa, Andrea Giansanti
The melting curves of short heterogeneous DNA chains in solution are calculated on the basis of statistical thermodynamics and compared to experiments. The computation of the parti…
