From phase synchronization to waveform proportionality in a population of Rössler oscillators driven by an external pacemaker
Yuzuru Mitsui, Shigefumi Hata, Hiroshi Kori
The dynamical order of self-sustained oscillators is often characterized by phase synchronization, extensively studied within the framework of the Kuramoto model. It has recently b…
Degree heterogeneity shapes escape mechanisms in networks of diffusively coupled bistable elements
Hidemasa Ishii, Hiroshi Kori
For fully connected populations of diffusively coupled bistable elements, we identified three qualitatively distinct mechanisms of noise-induced escape as coupling strength varies…
Inferring Coupled Stuart-Landau Equations from Waveforms
Yuki Araya, Hiroaki Ito, Hiroshi Kori +1
We present a data-driven framework to infer phase-amplitude equations of coupled limit-cycle oscillators directly from waveform measurements. Exploiting the universality of the Stu…
Waveform proportionality and Taylor's law in networks of Lorenz systems
Yuzuru Mitsui, Hiroshi Kori
Taylor's law (TL), a power-law relationship between the mean and variance of a quantity, has been observed across diverse scientific disciplines. Despite its ubiquity, the underlyi…
Distinguishing pairwise and higher-order interactions in coupled oscillators from time series
Weiwei Su, Shigefumi Hata, Hiroshi Kori +2
Rhythmic phenomena, which are ubiquitous in biological systems, are typically modelled as systems of coupled limit cycle oscillators. Recently, there has been an increased interest…
Multistability and Control in Ring Networks of Phase Oscillators with Frequency Heterogeneity and Phase Lag
Soomin Kim, Hiroshi Kori
Many oscillator networks are multistable, meaning that different synchronization states are realized depending on the initial conditions. In this paper, we numerically analyze a ri…
Network inference applicable to both synchronous and desynchronous systems from oscillatory signals
Akari Matsuki, Hiroshi Kori, Ryota Kobayashi
Synchronization is ubiquitous in nature, which is mathematically described by coupled oscillators. Synchronization strongly depends on the interaction network, and the network play…
Forecasting the Forced van der Pol Equation with Frequent Phase Shifts Using Reservoir Computing
Sho Kuno, Hiroshi Kori
We tested the performance of reservoir computing (RC) in predicting the dynamics of a certain non-autonomous dynamical system. Specifically, we considered a van del Pol oscillator…
