Asymptotic stability and bifurcations of a perturbed McMillan map

Journal of Inequalities and Applications
This paper presents various bifurcations of the McMillan map under perturbations of its coefficients, such as period-doubling, pitchfork, and hysteresis bifurcation. The associated existence regions are located.

Bifurcation Boundary Conditions for Switching DC-DC Converters Under Constant On-Time Control

, 2012
Sampled-data analysis and harmonic balance analysis are applied to analyze switching DC-DC converters under constant on-time control. Design-oriented boundary conditions for the period-doubling bifurcation and the saddle-node bifurcation are derived. The

‘Let's Turn the Grass Into Meat’: Animal Husbandry as Women's Work in Cold War North Korea

Gender &History, EarlyView.
ABSTRACT In postcolonial North Korea, the future of the nation was said to be a function of the feedlot. Unobtainable on the battlefields of the recently ended Korean War, liberation and unification of the peninsula became a question of competitive developmentalism.

Complex dynamics of a three species food-chain model with Holling type IV functional response

Nonlinear Analysis, 2011
In this paper, dynamical complexities of a three species food chain model with Holling type IV predator response is investigated analytically as well as numerically. The local and global stability analysis is carried out. The persistence criterion of the

A New Feigenbaum-Like Chaotic 3D System

Discrete Dynamics in Nature and Society, 2014
Based on Sprott N system, a new three-dimensional autonomous system is reported. It is demonstrated to be chaotic in the sense of having positive largest Lyapunov exponent and fractional dimension. To further understand the complex dynamics of the system,

Using Nyquist or Nyquist-Like Plot to Predict Three Typical Instabilities in DC-DC Converters

, 2012
By transforming an exact stability condition, a new Nyquist-like plot is proposed to predict occurrences of three typical instabilities in DC-DC converters.

Period-doubling bifurcation in spatiotemporal mode-locked lasers

, 2020
Period-doubling bifurcation is a universal dynamic of nonlinear systems, which has been extensively investigated in laser systems with a single transverse mode. This study presents an experimental observation and theoretical investigation of the period-doubling bifurcation in spatiotemporal mode-locked (STML) multimode fiber lasers.

TNF Pathway‐Mediated Tolerogenic T‐Cell Trajectory Driven by Allergen Immunotherapy

Allergy, EarlyView.
The study shows that AIT re‐establishes local immune equilibrium by restoring Th17/Treg balance, while circulating Th17 cells remain functionally impaired. The transition from pro‐inflammatory Th17 to regulatory T cell states during AIT identifies Tr17 cells as an intermediate cell population.

Dynamical Regimes in a Delayed Predator–Prey Model with Predator Hunting Cooperation: Bifurcations, Stability, and Complex Dynamics

Modelling
In this paper, a predator–prey model with hunting cooperation and maturation delay is studied. Through theoretical analysis, we investigate the existence of multiple stability switches of the positive equilibrium. By applying Hopf bifurcation theory, the
