Based on recent approaches in terms of Universality classes, this paper reexamines the analysis of the growth-accommodation processes in [1] regarding photo-relaxation processes of magnetic materials (low complexity). Also the analysis is extended to compression-decompression (hysteresis) processes for rich complexity materials (sandstones). The fitting accuracies of the growthaccommodation pro...

The human brain undergoes rapid and dynamic development early in life. Assessment of brain growth patterns relevant to neurological disorders and disease requires a normative population model of growth and variability in order to evaluate deviation from typical development. In this paper, we focus on maturation of brain white matter as shown in diffusion tensor MRI (DT-MRI), measured by fractio...

For treating cancer, tumor growth models have shown to be a valuable resource, whether they are used develop therapeutic methods paired with process control or simulate and evaluate treatment processes. In addition, fuzzy mathematical model is tool for monitoring the influences of various elements creating behavioral assessments. It has been designed decrease ambiguity parameters obtain reliabl...

We defend the hypothesis that life-spanning population survivorship curves, as described by Gompertz' law and composed from cross-sectional data (here mortality), reflect an intrinsic aging principle active in each subject of that population. In other words Gompertz' law reflects aging of a prototypical subject, provided minimal (or no) external causes of death (i.e. fatal infections, starvatio...
