项目摘要

In the study of biological systems, we frequently encounter problems associated with hierarchical phenomena and structrues. As a result of development of the both experiment and theory, the microscopic analyzes of hierarchical phenomena and structures is being studied intensively. In the present study, however, we considered the hierarchical phenomena and structures based upon the studies on nonlinear and nonequilibrium phenomena. In biologically related systems, Hatta discussed sequential mechanism of phase transition in heterogeneous biological systems, Yoshikawa et al.performed direct observation of the coil-globule transition in DNA molecules, Kakitani discussed relationship between four-state delineation and two-state delineation in electron transfer reactions and excitation transfer, Kawakubo et al.discussed convective instability and electric potential oscillation in a water-oil-water system, Kuramoto et al.discussed anomalous Lyapunov spectrum in globally coupled oscillators, and Kushida et al.studied structural dynamics of proteins by hole-burning spectroscopy. In living biological systems, Ueda discussed pattern dynamics in cellar perception, Sawada discussed a scaling theory of living state, Tsuchiya et al.discussed synchronization in a plasmodial strand of physarum polycephalum as a one-dimensional coupled oscillator system, and Kai et al.discussed morphogenesis and bioluminescence in germination of red beam. In systems related to human being, Shimizu discussed biological autonomy : the selfcreation of constrainta, Musha et al.discussed location of electric current sources in the human brain estimated by the dipole tracing method of the scalp-skull-brain head model, and Hirakawa et al.discussed phase dynamics in entrained alpha rhythms by photic stimulation.

在对生物系统的研究中，我们经常遇到与层次现象和结构相关的问题。由于实验和理论的发展，正在深入研究层次现象和结构的微观分析。然而，在本研究中，我们根据对非线性和非平衡现象的研究考虑了分层现象和结构。在与生物学相关的系统中，Hatta讨论了异质生物系统中相变的顺序机制，Yoshikawa等人在DNA分子中直接观察了对螺旋群的直接观察，Kakitani讨论了四态分段和两态的电脉中的脉动及其在电脉中的四个状态划分之间的关系Kuramoto等人在防水水系统中的振荡在全球耦合振荡器中脱离了异常的Lyapunov光谱，以及Kushida等人通过燃烧光谱的蛋白质进行了蛋白质的结构动力学。 In living biological systems, Ueda discussed pattern dynamics in cellar perception, Sawada discussed a scaling theory of living state, Tsuchiya et al.discussed synchronization in a plasmodial strand of physarum polycephalum as a one-dimensional coupled oscillator system, and Kai et al.discussed morphogenesis and bioluminescence in germination of red beam.在与人类相关的系统中，Shimizu讨论了生物学自主：约束的自我创造，Musha等人在人脑中电流源的位置通过偶极性跟踪方法估算了头皮 - 毛毛 - 脑头模型的偶极性跟踪方法，以及Hirakawa等人的hirakawa等人，以及在含有光谱中被吸收的alpha rhpha rhypha rhypha rhythms的动态。
