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，分层现象和结构的微观分析正在得到深入研究。然而，在本研究中，我们基于对非线性和非平衡现象的研究来考虑分层现象和结构。在生物相关系统中，Hatta讨论了异质生物系统中相变的顺序机制，Yoshikawa等人对DNA分子中的线圈-球体转变进行了直接观察，Kakitani讨论了电子转移中四态描绘和二态描绘之间的关系反应和激发传递，Kawakubo 等人讨论了水-油-水系统中的对流不稳定性和电势振荡，Kuramoto 等人讨论了反常 Lyapunov 谱全局耦合振荡器，Kushida 等人通过烧孔光谱研究了蛋白质的结构动力学。在活生物系统中，Ueda 讨论了地窖感知中的模式动力学，Sawada 讨论了生命状态的标度理论，Tsuchiya 等人讨论了作为一维耦合振荡器系统的多头绒泡胞浆菌链中的同步，Kai 等人讨论了红光束萌发中的形态发生和生物发光。在与人类相关的系统中，Shimizu讨论了生物自主性：约束的自我创造，Musha等人讨论了通过头皮-颅骨-大脑头部模型的偶极子追踪方法估计的人脑中电流源的位置，Hirakawa等人讨论了等人讨论了光刺激引起的α节律的相位动力学。
