Ulam's stability of neutral fractional stochastic differential equation with the application of homeostasis circuit
In this paper, Ulam’s stability of neutral fractional stochastic differential equations (NFSDEs) with sub-fractional Brownian motion (sfBm) is studied. Existence and stability results are established using fixed point theory, semigroup theory, and fractional calculus in a stochastic setting. We modify unstable impulses into stable impulses in the signal transformation of the cell tissue trajectory. Numerical simulations are provided to verify the obtained results. Fractional components are used to construct a fractional-order analogue circuit model for an artificial tissue homeostasis circuit, which is relevant to the application features. The proposed circuit offers several advantages for framing effective cell populations, including (i) predicting the death of β cells at the microscopic level for type 1 diabetics, (ii) regenerating the dead cells through stem cells, and (iii) achieving stable signal transformation between β cells and stem cells.
