Stability of equilibria in quantitative genetic models based on modified-gradient systems

Journal of Biological Dynamics, 2018
Motivated by questions in biology, we investigate the stability of equilibria of the dynamical system $ \mathbf {x}^{\prime }=P(t)\nabla f(x) $ which arise as critical points of f, under the assumption that $ P(t) $ is positive semi-definite. It is shown

Multistability and variations in basin of attraction in power-grid systems

New Journal of Physics, 2018
Power grids sustain modern society by supplying electricity and thus their stability is a crucial factor for our civilization. The dynamic stability of a power grid is usually quantified by the probability of its nodes’ recovery to phase synchronization ...

Niching-Driven Divide-and-Conquer Hill Exploration

Applied System Innovation
Optimization problems often feature local optima with a significant difference in the basin of attraction (BoA), making evolutionary computation methods prone to discarding solutions located in less-attractive BoAs, thereby posing challenges to the ...

Identification of basins of attraction in the local Universe

Nature Astronomy
Structure in the Universe is believed to have evolved out of quantum fluctuations seeded by inflation in the early Universe. These fluctuations lead to density perturbations that grow via gravitational instability into large cosmological structures.

Magnetic potential tuning in a typical piezoelectric energy harvesting system: bistable versus tristable capability under initial-state sensitivity

Theoretical and Applied Mechanics Letters
This study presents a theoretical framework for analyzing a magnetically coupled multi-stable piezoelectric energy harvesting (PEH) system, comparing bistable and tristable configurations under initial perturbations.
