TLDR
In this paper, it was shown that the complex deformation of the same data can be represented by a function of same form but with different values for the constants, which can be interpreted as the decay of the distortion with time of the removal of stress field.About:

Molecular Dynamics of PEG-Dendrimer Blends and PEGylated Dendrimers
Sanja Natali,Jovan Mijovic +1 more
TL;DR: Molecular dynamics of a series of poly(ethylene glycol)−poly(amidoamine) (PEG−PAMAM) dendrimer blends and PEG conjugated PAMAM d endrimers were investigated and contrasted using broadband dielectric relaxation spectroscopy (DRS).

Dielectric relaxation and thermodynamic properties of polyvinylpyrrolidone using time domain reflectometry
TL;DR: In this article, temperature-dependent values of dielectric permittivity e′ and dielectrics loss e″ of polyvinylpyrrolidone (PVP, commercialized as PVP K-60) solution of average molecular weight 160 000 g mol−1 were measured.

Thermal behavior and molecular mobility studies in the supercooled liquid and glassy states of carvedilol and loratadine
TL;DR: The thermal behavior of carvedilol and loratadine was studied by differential scanning calorimetry (DSC), and the DRS investigation allowed to better understand the molecular dynamics in carveilol in the amorphous solid, in the metastable liquid state and in the glass transformation region.

TL;DR: In this paper, the average inclusion strain in the matrix of a two-phase polymer is evaluated using elementary cubes, where the bulk sample is partitioned in small elementary cubes and the size of the elementary cubes of the partition is chosen to allow for the accurate representation of the material properties.

Cooperative Dynamics in Polystyrene and Low-Mass Molecule Mixtures
TL;DR: In this paper, the authors conducted dielectric and viscoelastic relaxation measurements for polystyrene (PS)/4-pentyl-4′-cyanobiphenyl (5CB) and PS/4- pentyl- 4′-cyclanoterphenyl(5CT) mixtures in the miscible state with the weight fractions of 5CB or 5CT from 0.04 to 0.27.

A treatise on the mathematical theory of elasticity
TL;DR: Webb's work on elasticity as mentioned in this paper is the outcome of a suggestion made to me some years ago by Mr R. R. Webb that I should assist him in the preparation of a work on Elasticity.
