The entropy production rate was determined for avascular tumor growth. The proposed formula
relates the fractal dimension of the tumor contour with the quotient between mitosis and …

We propose a mechanism for avascular tumor growth based on a simple chemical network.
This model presents a logistic behavior and shows a “second order” phase transition. We …

Asphaltenes aggregation and waxes in petroleum were simulated considering five molecular
structures containing functional groups: asphaltenes, resins, and non-polar hydrocarbons …

We propose a mechanism for prostate cancer cell lines growth, LNCaP and PC3 based on
a Gompertz dynamics. This growth exhibits a multifractal behavior and a “second order” …

A mechanism to describe the apoptosis process at mesoscopic level through p53 is proposed
in this paper. A deterministic model given by three differential equations is deduced from …

… equal to zero obtaining:(23) Φ = k β g A e s p α e s p (24) σ = 1 Ω ( k β g A e s p α e s p + Φ ) …

The mathematical modeling of tumor growth allows us to describe the most important regularities
of these systems. A stochastic model, based on the most important processes that take …

El presente trabajo evalúa la calidad de agua del río Portoviejo (Manabí, Ecuador)
mediante la aplicación del índice de calidad de agua bajo la metodología propuesta por la …

The high viscosity and low surface tension of heavy crude oils, combined with the low relative
permeability of the medium, cause their entrapment in the porous reservoir nets, affecting …

In this work, we propose a mesoscopic model for tumor growth to improve our understanding
of the origin of the heterogeneity of tumor cells. In this sense, this stochastic formalism …
