Bianucci, Mannella, and Grigolini Reply

Bianucci, Mannella, and Grigolini Reply

Date: August 18, 1997
Creator: Bianucci, Marco; Mannella, Riccardo & Grigolini, Paolo
Description: This article is a reply to a comment by Massimo Falcioni and Angelo Vulpiani. In a previous letter, the authors have discussed the linear response theory (LRT) and shown that the breakdown of this theory occurring at intermediate times, observed in an earlier paper [2] as well as in [1], disappears upon an increase of the number of degrees of freedom. In a comment to [1] Falcioni and Vulpiani [3] claim that this breakdown is rather a consequence of the lack of mixing: according to them, regardless of the number of degrees of freedom, mixing is the key ingredient behind the LRT.

Dynamical approach to Lévy processes

Dynamical approach to Lévy processes

Date: November 1996
Creator: Allegrini, Paolo; Grigolini, Paolo & West, Bruce J.
Description: This article discusses a dynamical approach to Lévy processes, which makes it possible to derive all statistical properties of the diffusion process from the correlation function of the dichotomous fluctuating variable Φy(t).

Dynamical model for DNA sequences

Dynamical model for DNA sequences

Date: November 1995
Creator: Allegrini, Paolo; Barbi, M.; Grigolini, Paolo & West, Bruce J.
Description: This article discusses a dynamical model for DNA sequences based on the assumption that the statistical properties of DNA paths are determined by the joint action of two processes, one deterministic with long-range correlations and the other random and δ-function correlated.

Fractional Brownian motion as a nonstationary process: An alternative paradigm for DNA sequences

Fractional Brownian motion as a nonstationary process: An alternative paradigm for DNA sequences

Date: April 1998
Creator: Allegrini, Paolo; Buiatti, Marco, 1972-; Grigolini, Paolo & West, Bruce J.
Description: This article discusses fractional Brownian motion as a nonstationary process. The model adopted is compatible with the known biological and physical constraints, namely, it is shown to be consistent with the information of current biological literature on folding as well as with the statistical analyses of DNA sequences.
