THEORETICAL STUDIES OF DYNAMICAL PROCESSES IN CHEMICAL PHYSICS AND BIOPHYSICS

研究的总体焦点一直是无序的速率过程 系统。一项研究涉及无序介质中的扩散，以及 尤其是与时间和空间相关的波动的影响 扩散系数。IBIS可能有助于理解 细胞内生化过程中的化学动力学。一秒钟内 研究发现，对Berg和Purcell的理论进行了新的处理 与随机分布的受体的扩散控制的配基结合 细胞的表面。除了提高我们对他们的理解之外 理论上，新的治疗方法在精确度上有了适度的改善。在一个 第三个领域，已经写了关于理论方法的主要评论 已经被发明用来处理动力学过程，其中速率常数可以 在时间上波动(动态无序)。因为有很多领域 化学物理和生物物理，其中动力学无序是重要的 (例如，蛋白质动力学或荧光去极化)，统一处理 在已经提出的各种方法中，预计一般 很有用。

The general focus of research has been on rate processes in disordered systems. One investigation dealt with diffusion in a disordered medium, and in particular with the effects of time- and space-dependent fluctuations in the diffusion coefficient. Ibis is potentially useful in understanding chemical kinetics in biochemical processes in cells. In a second investigation, a new treatment has been made of Berg and Purcell's theory of diffusion controlled ligand binding to receptors randomly distributed on the surface of a cell. Aside from improving on our understanding of their theory, the new treatment makes a modest improvement on its accuracy. In a third area, a major review has been written about theoretical methods that have been invented to treat kinetic processes where rate constants can fluctuate in time (dynamical disorder). Since there are many areas of chemical physics and biophysics in which dynamical disorder is important (e.g. protein dynamics or fluorescence depolarization), a unified treatment of the various methods that have been proposed is expected to be generally useful.
