Robotnov function based operator for biological population model of biology

open access: closedInternational Journal of Numerical Methods for Heat & Fluid Flow, 2021
Purpose The population model has an important role in biology to interpret the spreading rate of viruses and parasites. This biological model is also used to identify fragile species. This paper aims to propose a new Yang-Abdel-Aty-Cattani (YAC) fractional operator with a non-singular kernel to solve nonlinear partial differential equation, which is ...

Analysis of Degenerate Diffusion Operators Arising in Population Biology

open access: closed, 2012
In this chapter, we describe our recent work on the analytic foundations for the study of degenerate diffusion equations which arise as the infinite population limits of standard models in population genetics. Our principal results concern existence, uniqueness, and regularity of solutions when the data belong to anisotropic Holder spaces, adapted to ...

Stochastic Operators and Semigroups and Their Applications in Physics and Biology

open access: closed, 2014
Stochastic operators are positive linear operators defined on the space of integrable functions preserving the set of densities. They appear in many fields of mathematics and applications and they are use to study ergodic properties of dynamical systems and describe the evolution of Markov chains.

Co-Operation of Biology Related Algorithms

2013 IEEE Congress on Evolutionary Computation, 2013
A new meta-heuristic algorithm, called Co-Operation of Biology Related Algorithms (COBRA), for solving real-parameter optimization problems is introduced and described. The algorithm is based on cooperation of biologically inspired algorithms such as Particle Swarm Optimization (PSO), Wolf Pack Search Algorithm (WPS), Firefly Algorithm (FFA), Cuckoo ...

Towards a theory of meaning in biology: a proposal for an operative definition.

Rivista di biologia, 2003
Information is a concept developed inside the context of computational and computer sciences. Entropy is a concept developed inside physics context. The best concept in biology is that of "meaning" which is quite impossible to be measured as stated by some examples which are reported.
