On the Limit Cycle of an Inflationary Universe [PDF]

open access: yes, 1996
We study the dynamics of a scalar inflaton field with a symmetric double--well potential and prove rigorously the existence of a limit cycle in its phase space.

The Gravo-Magneto Limit Cycle in Accretion Disks

open access: yes, 2011
Previous theoretical studies have found that repeating outbursts can occur in certain regions of an accretion disk, due to sudden transitions in time from gravitationally produced turbulence to magnetically produced turbulence.

Intravitreal GD2‐Specific Chimeric Antigen Receptor T‐Cell Therapy for Refractory Retinoblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Effective treatments for advanced, treatment‐resistant retinoblastoma (RB) remain limited. GD2‐specific chimeric antigen receptor (CAR) T cells show potent antitumor activity with minimal toxicity but have not previously been evaluated in RB.

Limit cycles of Liénard polynomial systems type by averaging method

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020

Semiclassical Phase Reduction Theory for Quantum Synchronization

open access: yes, 2019
We develop a general theoretical framework of semiclassical phase reduction for analyzing synchronization of quantum limit-cycle oscillators. The dynamics of quantum dissipative systems exhibiting limit-cycle oscillations are reduced to a simple, one ...

Synchronization in two-level quantum systems

open access: yes, 2020
Recently, it was shown that dissipative quantum systems with three or more levels are able to synchronize to an external signal, but it was stated that it is not possible for two-level systems as they lack a stable limit cycle in the unperturbed dynamics.

Nonlinear Dynamics and Economic Instability: The Optimal Management of a Biological Population

open access: yesJournal of Agricultural and Resource Economics, 1995
Assuming a competitive market, conditions are determined for when a steady-state equilibrium does not exist in the optimal dynamic management of a biological population.

On the cyclicity of Kolmogorov polycycles

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper we study planar polynomial Kolmogorov's differential systems \[ X_\mu\quad\begin{cases}{\dot{x}=f(x,y;\mu),}\\{\dot{y}=g(x,y;\mu),} \end{cases} \] with the parameter $\mu$ varying in an open subset $\Lambda\subset\mathbb{R}^N ...

Multiplicity of Limit Cycle Attractors in Coupled Heteroclinic Cycles

open access: yes, 2002
A square lattice distribution of coupled oscillators that have heteroclinic cycle attractors is studied. In this system, we find a novel type of patterns that is spatially disordered and periodic in time.

Landscapes of Non-gradient Dynamics Without Detailed Balance: Stable Limit Cycles and Multiple Attractors [PDF]

open access: yes, 2012
Landscape is one of the key notions in literature on biological processes and physics of complex systems with both deterministic and stochastic dynamics.
