Dynamic configurational fluctuation

It has often been assumed that the second step, intracomplex ET, takes place within a static reactant complex. However, a number of cases have been observed in which the reactant complex is not static, but undergoes dynamic configurational fluctuations (defined as protein-protein orientations in the bound complex) [65] or conformational changes (defined as a tertiary structure of each protein) [40]. If the reaction is rate limited by dynamic fluctuation in configuration rather than by the... 

Thus we see that as in the case of rods, the coil must be large enough so that its configurational fluctuations can be seen by the light wave in order for configurational dynamic constants to affect the scattered field time-correlation function.

We have seen that the cooperative region, which represents a nominal dynamical unit of liquid, is of rather modest size, resulting in observable fluctuation effects. Xia and Wolynes [45] computed the relaxation barrier distribution. The configurational entropy must fluctuate, with the variance given by the usual expression [77] 5Sc) ) = Cp barrier height for a particular region is directly related to the local density of states, and hence to... 

Pressure detection shall be used for closed enclosure applications. Threshold detectors provide an electric signal when a preset overpressure is exceeded. Dynamic detectors provide an electric signal to the control and indicating equipment (CIE). Typically they have both rate-of-rise and pressure threshold triggering points that can be configured specifically to the application conditions. Although this type of detector minimizes spurious activation of the isolation system (due to pressure fluctuations other than explosion pressure rise), care shall be taken to set up such detectors to meet appropriate detection response criteria for the particular application and protected enclosure geometry. 

The solvent oscillators could have been normalized in a similar manner which explains why the linear term was not incorporated from the beginning. Note that the terms added do not affect the dynamics they are constant quantities that might be different for the different transient configurations. The linear term introduced by the solute on to the solvent can be altogether neglected. The model fluctuation Hamiltonian can be written now as ... 

Currently suggested models for tunneling increasingly invoke protein dynamics . These models envision either a series of conformational fluctuations that lead to a suitable tunnehng configuration ( passive dynamics ) or a more active role...
