Recent notices

• July 2nd, 2024: Oral presentation at Joint annual meeting of the Korean Society for Mathematical Biology and the Society for Mathematical Biology.  

• May 31st, 2024: Our new paper has been published in arXiv. In a bistable oscillator model, we find that multiplicative periodic forces combined with feedback induce oscillation quenching, a transition from a limit cycle to a fixed point. 

• January 17th, 2024: Our paper has been published in Scientific Reports. In this article, we proposed a simple model of coupled mechanical oscillators (e.g. metronomes) and analyzed both synchronization and quenching by performing weakly nonlinear analysis. Numerical bifurcation analyses of out-of-phase synchronization and beat-like solution are also addressed, which are highlighted in Figs. 5 and 6. 

• November 21st, 2023:  I will give an oral presentation at Young Soft Webinar. 

• November 14th, 2023: Our preprint has been published in arXiv. We propose a simple metronome model and analyze not only the synchronization but also oscillation quenching, which had not been investigated a lot in previous studies.
