Bifurcation Diagram for Compartmentalized Granular Gases [PDF]

, 2001
The bifurcation diagram for a vibro-fluidized granular gas in N connected compartments is constructed and discussed. At vigorous driving, the uniform distribution (in which the gas is equi-partitioned over the compartments) is stable.

Action functional as an early warning indicator in the space of probability measures via Schrödinger bridge

Quantitative Biology, Volume 13, Issue 3, September 2025.
Abstract Critical transitions and tipping phenomena between two meta‐stable states in stochastic dynamical systems are a scientific issue. In this work, we expand the methodology of identifying the most probable transition pathway between two meta‐stable states with Onsager–Machlup action functional, to investigate the evolutionary transition dynamics ...

Nonlocal Cooperative Behavior, Psychological Effects, and Collective Decision‐Making: An Exemplification With Predator–Prey Models

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 12011-12037, August 2025.
ABSTRACT In bio‐social models, cooperative behavior has evolved as an adaptive strategy, playing multi‐functional roles. One of such roles in populations is to increase the success of the survival and reproduction of individuals and their families or social groups.

Bifurcation diagram for saddle/source bimodal linear dynamical systems [PDF]

, 2016
We continue the study of the structural stability and the bifurcations of planar bimodal linear dynamical systems (BLDS) (that is, systems consisting of two linear dynamics acting on each side of a straight line, assuming continuity along the separating ...

Physics‐Based Indicators for the Onset of an AMOC Collapse Under Climate Change

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.
Abstract The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the 21st $21\text{st}$ century under future climate change, as this requires long climate model simulations which are not always available.

Bistable Chimera Attractors on a Triangular Network of Oscillator Populations

, 2010
We study a triangular network of three populations of coupled phase oscillators with identical frequencies. The populations interact nonlocally, in the sense that all oscillators are coupled to one another, but more weakly to those in neighboring ...

The Twisting Bifurcations of Double Homoclinic Loops with Resonant Eigenvalues

Abstract and Applied Analysis, 2013
The twisting bifurcations of double homoclinic loops with resonant eigenvalues are investigated in four-dimensional systems. The coexistence or noncoexistence of large 1-homoclinic orbit and large 1-periodic orbit near double homoclinic loops is given ...

Backward bifurcation and saddle-node bifurcation in virus-immune dynamics

, 2021
Recently, Wang and Xu [ Appl. Math. Lett. 78 (2018) 105-111] studied thresholds and bi-stability in virus-immune dynamics. In this paper, we show there also exist backward bifurcation and saddle node bifurcation in this model. Our investigation demonstrates the existence of post-bifurcation phenomenon in the system when the immune strength was selected

Mechanical Resonant Sensing of Spin Texture Dynamics in a 2D Antiferromagnet

Advanced Materials, Volume 37, Issue 29, July 24, 2025.
Detection of antiferromagnetic spin texture in a 2D magnetic crystal is achieved through nanomechanical resonators at radio frequencies. Sharp magnetic transitions that lead to abrupt changes in mechanical linear and nonlinear responses are assigned to antiferromagnetic domain motions.

Thermal Evolution of Planetary Interiors With a Crystallizing Basal Magma Ocean Coupled to Parameterized Mantle Convection

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Basal magma oceans (BMOs) persisting in the silicate portion of terrestrial planets for long periods of time (> ${ >} $1 Gyr) offer the potential to reconcile unexplained contradictions between geochemical and geophysical observations, yet our knowledge of how the presence of such layers influence planetary evolution is far from mature.
