Zero-Hopf bifurcation and ultimate boundness of an asymmetrical hyperchaotic Lorenz system
Franklin Open, 2023 The complex dynamics of a newly proposed 4D hyperchaotic Lorenz-type system are studied in this paper. The sufficient conditions for the emergence and stability of periodic solutions at bifurcation points are derived using averaging theory.

Pseudo, or Not? Neo‐Goodwinian Growth Cycles With Financial Linkages
Metroeconomica, EarlyView.ABSTRACT A profit‐led Goodwin mechanism generates the observed counterclockwise activity–labor share cycle. Introducing a financial linkage can reproduce this pattern even when demand is not profit‐led. This paper extends neo‐Goodwinian theory by incorporating the valuation ratio into a four‐dimensional model.

Simple-Zero and Double-Zero Singularities of a Kaldor-Kalecki Model of Business Cycles with Delay
Discrete Dynamics in Nature and Society, 2009 We study the Kaldor-Kalecki model of business cycles with delay in both the gross product and the capital stock. Simple-zero and double-zero singularities are investigated when bifurcation parameters change near certain critical values.

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model
Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14697-14743, 15 September 2026.ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Engineering Reports, Volume 8, Issue 8, August 2026.An integrated hybrid energy storage and cogeneration system with CE‐DPS effectively stabilizes DC bus voltage in hydrogen fuel cell marine vessels. The proposed multi‐tier control suppresses voltage fluctuations, eliminates overshoot, and improves energy efficiency, achieving 68% exergy efficiency and 15.6% fuel savings.

Nonlinear Analysis, 2022 In this paper, we propose an HIV model with latent reservoir, delayed CTL immune response and immune impairment in which both virus-to-cell infection and cell-to-cell viral transmission are considered.

Mathematical Analysis and Simulations of a Cancer Model With Interleukins and Delayed Immunotherapy
Mathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13946-13970, August 2026.ABSTRACT A new system of delayed differential equations for tumor‐immune system interactions is proposed and studied. The system describes the interactions between tumor cells and the immune system at the most aggressive phase of cancer, where tumor cells have developed mechanisms from earlier stages to evade immune responses.

Advanced Physics Research, Volume 5, Issue 7, July 2026.Active reactance in electro‐thermal memristors emerges intrinsically from rapid thermal switching of device resistance, linking current‐controlled and voltage‐controlled negative differential resistance to neuronal spiking dynamics. Opposing temperature coefficients of resistance give rise to active inductive or capacitive responses, enabling tunable ...

Bifurcation Control in an Optimal Velocity Model via Double Time-Delay Feedback Method
IEEE Access, 2020 In this paper, a double time-delay feedback control of an optimal velocity model (OVM) is investigated. Double time-delay means that there exist two different state feedback control signals in the controlled OVM system, which are related to the velocity ...

Isolated periodic wave trains in a generalized Burgers–Huxley equation
Electronic Journal of Qualitative Theory of Differential Equations, 2022 We study the isolated periodic wave trains in a class of modified generalized Burgers–Huxley equation. The planar systems with a degenerate equilibrium arising after the traveling transformation are investigated.
