Fractional derivatives of random walks: Time series with long-time memory
H. Eduardo Roman, Markus Porto
We review statistical properties of models generated by the application of a (positive and negative order) fractional derivative operator to a standard random walk and show that th…
Prediction of site-specific amino acid distributions and limits of divergent evolutionary changes in protein sequences
Markus Porto, H. Eduardo Roman, Michele Vendruscolo +1
We derive an analytic expression for site-specific stationary distributions of amino acids from the Structurally Constrained Neutral (SCN) model of protein evolution with conservat…
Reconstruction of protein structures from a vectorial representation
Markus Porto, Ugo Bastolla, H. Eduardo Roman +1
We show that the contact map of the native structure of globular proteins can be reconstructed starting from the sole knowledge of the contact map's principal eigenvector, and pres…
Neutral evolution of model proteins: diffusion in sequence space and overdispersion
Ugo Bastolla, H. Eduardo Roman, Michele Vendruscolo
We simulate the evolution of model protein sequences subject to mutations. A mutation is considered neutral if it conserves 1) the structure of the ground state, 2) its thermodynam…
