| Outline of Final Research Achievements |
In this research project, we aim to propose a new design strategy of a large-scale bio-molecular circuit which has desired functions. To this end, the following two problems are addressed. 1) For interconnected nonlinear dynamical systems, a computational method of evaluating the robustness of the structural property was proposed. The method is applied to design problem of a bio-molecular switch that models the decision maker of cell fate. 2) We found a special class of dynamical systems that reinforce the robustness via their interconnection. The class is generalized to model a bio-molecular system that expresses the differentiation of a stem cell. It is mathematically shown that the robustness of a function derived from the differentiation is reinforced via bottom-up construction. The robustness reinforcement is illustrated in numerical experiments as well.
