The logistic equation in the context of Stieltjes differential and integral equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this paper, we introduce logistic equations with Stieltjes derivatives and provide explicit solution formulas. As an application, we present a population model which involves intraspecific competition, periods of hibernation, as well as seasonal ...

Improved Hille-Type Oscillation Criteria for Second-Order Quasilinear Dynamic Equations

open access: yesMathematics, 2022
In this work, we develop enhanced Hille-type oscillation conditions for arbitrary-time, second-order quasilinear functional dynamic equations. These findings extend and improve previous research that has been published in the literature.

Simplification of Galactic Dynamic equations [PDF]

open access: yesSymmetry, 2020
Most fully developed galaxies have vivid spiral structure, but the formation and evolution of spiral structure is still a mystery that is not fully understood in astrophysics. We find that the currently used equations of galactic dynamics contain some unreasonable components.

Stress Relaxation Properties and Microscopic Deformation Structure in Bending of the C7025 and C7035 Alloy

open access: yesCrystals, 2018
Stress relaxation tests in cantilever bending were performed on the C7025 and C7035 alloys at 298 K and 393 K, respectively. The effect of stress-relief treatments on stress relaxation properties was investigated.
