Award

Dr. Shingo Gibo received the Best Poster Award of the Japanese Society of Chronobiology. The title of the poster is "Analysis of the circadian period and phase synchronization based on waveform". Congratulations!

This is an abstract of the awards:
The circadian clocks are based on gene-activity rhythms with approximately 24-hour period, and its temporal waveforms are of various shapes. We theoretically showed that the waveform distortion contributes to the circadian period stability to temperature and entrainment to the environment cycles. Furthermore, by using the renormalization group method, which is developed in theoretical physics, we found that this relation between waveform and period holds not only for the circadian clock but also for many types of nonlinear oscillator models, including van der Pol and Lotka-Volterra model. This study is collaborated with physicists, Drs. Teiji Kunihiro (Kyoto University) and Tetsuo Hatsuda (iTHEMS).
