The master equation approach to configurational kinetics

the microstructural evolution was discussed by a number of authors.Most of these studies used Monte Carlo simulation and found the main features of the evolution via the direct and vacancy exchange mechanisms to be similar.In particular,the asymptotic growth law for the mean size of precipitates under spinodal decomposition,RThe evolution of white matter microstructural changes Neuroimaging biomarkers that can detect white matter (WM) pathology after mild traumatic brain injury (mTBI) and predict long-term outcome are needed to improve care and develop therapies.We used diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) to investigate WM microstructure cross-sectionally and longitudinally after mTBI and correlate these with The evolution of white matter microstructural changes INTRODUCTION.Despite increasing evidence from preclinical and human studies that mild traumatic brain injury (mTBI) causes axonal shearing injury of white matter (WM) microstructure that can affect the long-term cognitive,neuropsychiatric,and social domains of function,the lack of reliable objective tools to measure this pathology is a barrier to clinical translation (14).
