Dynamic mechanical analysis time-temperature correspondence

These thermally relevant characteristic values can be obtained by dynamic mechanical analysis (DMA). This analysis returns information about the way mechanical properties change under slight, usually sinusoidal dynamic loading as a function of temperature, time, and/or frequency. The periodic force (input signal) causes a corresponding response signal, namely deformation or strain in the viscoelastic test specimen, which can be evaluated for dynamic-elastic characteristic values in terms of amplitude and phase offset [36]. 

The value of ( used here corresponds to 10 3 of its value in room temperature aqueous solutions. [80] On the one hand, using such weak friction improves the sampling efficiency in the simulations and does not affect equilibrium structural properties. On the other hand, the dynamical properties that we observe may be different from those probed by SM-FRET techniques, which would not be able to resolve conformational dynamics on such fast time scales. Thus, the relevance of the following analysis of dynamical properties relies on the assumption that increasing the friction will not significantly alter our main conclusions. It is interesting to note in this context that the folding mechanism in similar models has been observed to be relatively insensitive to the value of the friction coefficient. [81]...
