Singularity bifurcations [PDF]

open access: yesJournal of Macroeconomics, 2006
equation models represent an important class of macroeconomic systems. Our ongoing research (He and Barnett (2003)) on the Leeper and Sims (1994) Euler equations macroeconometric model is revealing the existence of singularity-induced bifurcations, when the model¡¯s parameters are within a confidence region about the parameter estimates. Although known

The flatness of bifurcations in 3D dendritic trees: an optimal design

open access: yesFrontiers in Computational Neuroscience, 2012
The geometry of natural branching systems generally reflects functional optimization. A common property is that their bifurcations are planar and that daughter segments don’t turn back in the direction of the parent segment.

Stochastic Bifurcations and Excitement in the ZS-Model of a Thermochemical Reaction

open access: yesMathematics, 2022
The Zeldovich–Semenov model of the continuous stirred tank reactor with parametric random disturbances in temperature is considered. We study a phenomenon of noise-induced transformation of the equilibrium mode into the mixed-mode oscillatory stochastic ...

Electron bifurcation [PDF]

open access: yesCurrent Opinion in Chemical Biology, 2016
Electron bifurcation is the recently recognized third mechanism of biological energy conservation. It simultaneously couples exergonic and endergonic oxidation-reduction reactions to circumvent thermodynamic barriers and minimize free energy loss.

Bifurcation and criticality [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2019
Abstract Equilibrium and nonequilibrium systems exhibit power-law singularities close to their critical and bifurcation points respectively. A recent study has shown that biochemical nonequilibrium models with positive feedback belong to the universality class of the mean-field Ising model.

Single-Mode and Dual-Mode Nongomogeneous Dissipative Structures in the Nonlocal Model of Erosion

open access: yesМоделирование и анализ информационных систем, 2015
We consider a periodic boundary-value problem for a nonlinear equation with the deviating spatial argument in the case when the deviation is small. This equation is called a spatially nonlocal erosion equation.

Agricultural and economic systems in the conditions оf enhancing exogenic and endogenous turbulence [PDF]

open access: yesЕкономіка та управління АПК, 2020
The common problems and patterns of development of nature, economy, society, which are in a state of order, disorder, crisis, catastrophe or chaos have become the basis for the conclusion about the unity of their basis.

Bifurcations of stationary manifolds formed in the neighborhood of equilibrium in the dynamic cutting system

open access: yesAdvanced Engineering Research, 2015
The work objective is to study the formation of orbitally asymptotically stable limit cycles and two-dimensional invariant tori including bifurcations near the attracting sets. The investigators use primarily methods based on the mathematic simulation of

Bifurcation transitions in dynamic systems of pulse voltage regulator

open access: yesФизика волновых процессов и радиотехнические системы, 2020
In this article bifurcations in nonlinear dynamical systems are considered and special attention is paid to bifurcations-crises, which are identified with catastrophes in systems.

A Computational Study of Chaotic Flow and Heat Transfer within a Trapezoidal Cavity

open access: yesEnergies, 2023
Numerical findings of natural convection flows in a trapezoidal cavity are reported in this study. This study focuses on the shift from symmetric steady to chaotic flow within the cavity.
