Complex Dynamics Analysis of a Discrete Amensalism System with a Cover for the First Species
Axioms, 2022 Of interest is the dynamics of the discrete-time amensalism model with a cover on the first species. We first obtain the existence and stability of fixed points and the conditions for the permanent coexistence of two species.

Fabric on fabric: A conductive fabric-based wearable coil using cutting plotter for MRI at 3T. [PDF]
Magn Reson MedAbstract PurposeWearable coils fabricated using conductive threads have high resistance that limits SNR. The purpose of this work is to demonstrate the utility of conductive fabric as a coil conductor that can be fabricated using a cutting plotter. MethodsA single‐channel coil was developed by feeding a conductive fabric sheet into an automatic cutting

Bifurcation of a heterodimensional cycle with weak inclination flip
Discrete & Continuous Dynamical Systems - B, 2012 Local moving frame is constructed to analyze the bifurcation of a heterodimensional cycle with weak inclination flip in $\mathbb{R}^4$. Under some generic hypotheses, the existence conditions for the heteroclinic orbit, $1$-homoclinic orbit, $1$-periodic orbit and two-fold or three-fold $1$-periodic orbit are given, respectively.

Complicate dynamical analysis of a discrete predator-prey model with a prey refuge
AIMS Mathematics, 2023 In this paper, some complicated dynamic characteristics are formulated for a discrete predator-prey model with a prey refuge. After studying the local dynamical properties about fixed points, our main purpose is to investigate condition(s) for the ...

Bifurcation Analysis of Homoclinic Flips at Principal Eigenvalues Resonance
Applied Mathematics, 2013 One orbit flip and two inclination flips bifurcation is considered with resonant principal eigenvalues. We introduce a local active coordinate system to establish bifurcation equation and obtain the conditions when the original homoclinic orbit is kept or broken.

Hopf-flip bifurcations of vibratory systems with impacts [PDF]
Nonlinear Analysis: Real World Applications, 2005 Two vibro-impact systems are considered. The period n single-impact motions and Poincaré maps of the vibro-impact systems are derived analytically. Stability and local bifurcations of single-impact periodic motions are analyzed by using the Poincaré maps.

Computation of periodic solution bifurcations in ODEs using bordered systems [PDF]
, 2002 We consider numerical methods for the computation and continuation of the three generic secondary periodic solution bifurcations in autonomous ODEs, namely the fold, the period-doubling (or flip) bifurcation, and the torus (or Neimark–Sacker) bifurcation.

A Novel Discrete-Time Leslie–Gower Model with the Impact of Allee Effect in Predator Population
Complexity, 2022 The discrete-time system has more complex and chaotic dynamical behaviors as compared to the continuous-time system. This paper extends a discrete Leslie–Gower predator-prey system with the Allee effect in the predator’s population, whose dynamics are ...

Variational description of Gibbs-non-Gibbs dynamical transitions for the Curie-Weiss model [PDF]
, 2012 We perform a detailed study of Gibbs-non-Gibbs transitions for the Curie-Weiss model subject to independent spin-flip dynamics ("infinite-temperature" dynamics).
