Modeling of Sensory Characteristics Based on the Growth of Food Spoilage Bacteria
D. Valenti, G. Denaro, F. Giarratana +6
During last years theoretical works shed new light and proposed new hypothesis on the mechanisms which regulate the time behaviour of biological populations in different natural sy…
Noise Induced Phenomena in the Dynamics of Two Competing Species
D. Valenti, A. Giuffrida, G. Denaro +6
Noise through its interaction with the nonlinearity of the living systems can give rise to counter-intuitive phenomena. In this paper we shortly review noise induced effects in dif…
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)…
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…
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…
Coexistence of resonant activation and noise enhanced stability in a model of tumor-host interaction: Statistics of extinction times
A. Ochab-Marcinek, A. Fiasconaro, E. Gudowska-Nowak +1
We study a Langevin equation derived from the Michaelis-Menten (MM) phenomenological scheme for catalysis accompanying a spontaneous replication of molecules, which may serve as a…
Co-occurrence of resonant activation and noise-enhanced stability in a model of cancer growth in the presence of immune response
A. Fiasconaro, A. Ochab-Marcinek, B. Spagnolo +1
We investigate a stochastic version of a simple enzymatic reaction which follows the generic Michaelis-Menten kinetics. At sufficiently high concentrations of reacting species, the…
Noise in ecosystems: a short review
B. Spagnolo, D. Valenti, A. Fiasconaro
Noise, through its interaction with the nonlinearity of the living systems, can give rise to counter-intuitive phenomena such as stochastic resonance, noise-delayed extinction, tem…
