\section{Introduction}  \label{sec:Introduction}  - general introduction on the clock and cell cycle  - quick summary of what we did in the previous paper  - general introduction on modeling (dimensionality reduction, stochastic model)  $\textrm{d}\theta = 2\pi /{T_1} \textrm{d}t + f_1(\theta) + F_1(\theta,\phi) \textrm{d}t + \sigma_1 \textrm{d} W^1_t $  $\textrm{d}\phi = 2\pi /{T_2} \textrm{d}t + f_2(\phi) + F_2(\theta,\phi) \textrm{d}t + \sigma_2 \textrm{d} W^2_t $
