A stochastic interspecific competition model to predict the behaviour of Listeria monocytogenes in the fermentation process of a traditional Sicilian salami
Alessandro Giuffrida, Davide Valenti, Graziella Ziino +2
The present paper discusses the use of modified Lotka-Volterra equations in order to stochastically simulate the behaviour of Listeria monocytogenes and Lactic Acid Bacteria (LAB)…
Lifetime of the superconductive state in short and long Josephson junctions
Giuseppe Augello, Davide Valenti, Andrey L. Pankratov +1
We study the transient statistical properties of short and long Josephson junctions under the influence of thermal and correlated fluctuations. In particular, we investigate the li…
Evolutionary dynamics of imatinib-treated leukemic cells by stochastic approach
Nicola Pizzolato, Davide Valenti, Dominique Persano Adorno +1
The evolutionary dynamics of a system of cancerous cells in a model of chronic myeloid leukemia (CML) is investigated by a statistical approach. Cancer progression is explored by a…
Application of an interspecific competition model to predict the growth of Aeromonas hydrophila on fish surfaces during the refrigerated storage
Alessandro Giuffrida, Graziella Ziino, Davide Valenti +2
The growth of Aeromonas hydrophila and aerobic natural flora (APC) on gilthead seabream surfaces was evaluated during the refrigerated storage (21 days). The related growth curves…
Stochastic dynamics and mean field approach in a system of three interacting species
Davide Valenti, Bernardo Spagnolo
The spatio-temporal dynamics of three interacting species, two preys and one predator, in the presence of two different kinds of noise sources is studied. To describe the spatial d…
Volatility Effects on the Escape Time in Financial Market Models
Bernardo Spagnolo, Davide Valenti
We shortly review the statistical properties of the escape times, or hitting times, for stock price returns by using different models which describe the stock market evolution. We…
Environmental Metal Pollution Considered as Noise: Effects on the Spatial Distribution of Benthic Foraminifera in two Coastal Marine Areas of Sicily (Southern Italy)
D. Valenti, L. Tranchina, M. Brai +3
We analyze the spatial distributions of two groups of benthic foraminifera (Adelosina spp. + Quinqueloculina spp. and Elphidium spp.), along Sicilian coast, and their correlation w…
