Data-driven reconstruction of spatiotemporal phase dynamics for traveling and oscillating patterns via Bayesian inference
Takahiro Arai, Toshio Aoyagi, Yoji Kawamura
Building on the phase reduction theory formulated for reaction-diffusion systems with spatial translational symmetry, we develop a data-driven method that reconstructs the spatiote…
Phase reduction of reaction-diffusion systems with delay
Ayumi Ozawa, Yoji Kawamura
We develop a phase reduction method for reaction-diffusion systems with a discrete delay. On the basis of the recent developments in the phase reduction theory for infinite-dimensi…
Mineral Detection of Neutrinos and Dark Matter 2025 Proceedings
Shigenobu Hirose, Patrick Stengel, Natsue Abe +70
The third ``Mineral Detection of Neutrinos and Dark Matter'' (MDDM'25) meeting was held May 20-23, 2025 in Yokohama, Japan, hosted by the Yokohama Institute for Earth Sciences,…
Phase reduction analysis of traveling breathers in reaction--diffusion systems
Takahiro Arai, Yoji Kawamura
We formulate a theory for phase reduction analysis of traveling breathers in reaction--diffusion systems with spatial translational symmetry. In this formulation, the spatial and t…
Phase-based analysis and control of supersonic turbulent cavity flows
Vedasri Godavarthi, Yoji Kawamura, Lawrence S. Ukeiley +2
We present a phase-based framework for reducing the pressure fluctuations within a spanwise-periodic supersonic turbulent cavity flow with an incoming free-stream Mach number of 1.…
Setting of the Poincaré section for accurately calculating the phase of rhythmic spatiotemporal dynamics
Takahiro Arai, Yoji Kawamura, Toshio Aoyagi
The synchronization analysis of limit-cycle oscillators is prevalent in many fields, including physics, chemistry, and life sciences. It relies on the phase calculation that utiliz…
