| Outline of Final Research Achievements |
The spadix of skunk cabbage can generate and maintain an internal temperature of about 23oC even when the ambient air temperature drops below freezing. In the present study, we took the increment process of the temperature time series and consider it as an 'elastic' force that always tries to backlash its temperature to an intrinsic target temperature. Here, we proposed a mixed Poisson distribution for the model of the 'elastic' force, and our analyses resulted by Kolmogorov-Smirnov test showed that the proposed distribution is a plausible candidate of the model. Moreover, the parameters of the model well captured the linear behavior of the expectations of 'elastic' forces. Collectively, the linearity of the expected increments over displacements of temperatures indicated that the backlash could be considered as the elastic force of a spring as described by Fuch's law.
