Fuzzy fractional-order model of the novel coronavirus

open access: yesAdvances in Difference Equations, 2020
In this paper, a novel coronavirus infection system with a fuzzy fractional differential equation defined in Caputo’s sense is developed. By using the fuzzy Laplace method coupled with Adomian decomposition transform, numerical results are obtained for ...

Computational study of a co-infection model of HIV/AIDS and hepatitis C virus models

open access: yesScientific Reports, 2023
Hepatitis C infection and HIV/AIDS contaminations are normal in certain areas of the world, and because of their geographic overlap, co-infection can’t be precluded as the two illnesses have a similar transmission course.

Logical Entropy and Logical Mutual Information of Experiments in the Intuitionistic Fuzzy Case

open access: yesEntropy, 2017
In this contribution, we introduce the concepts of logical entropy and logical mutual information of experiments in the intuitionistic fuzzy case, and study the basic properties of the suggested measures. Subsequently, by means of the suggested notion of

Spatially organized dynamical states in chemical oscillator networks: synchronization, dynamical differentiation, and chimera patterns. [PDF]

open access: yesPLoS ONE, 2013
Dynamical processes in many engineered and living systems take place on complex networks of discrete dynamical units. We present laboratory experiments with a networked chemical system of nickel electrodissolution in which synchronization patterns are ...
