The assumption of gray matter homogeneity should be carefully considered in future finite element models of the head.
In this study, we extend our investigation of homogeneity to gray matter by measuring stiffness of cerebral cortex and comparing it to thalamus from our previous work.
In the matters of homogeneity and conformity of the target volume, the results are in disagreement: some studies showed an advantage of VMAT, reporting improved conformity or homogeneity, while other studies observed better results with fixed-field IMRT.
Bulk kinetic experiments reveal that a relatively narrow distribution of activation energies, range from 40 to 52 kcal/mol for the Kazhdumi samples and from 42 to 54 kcal/mol for Pabdeh shales, are directly related to the homogeneity in the organic matter.
To assess homogeneity and possible exchange of matter across the upper and lower boundaries of the Bottom Convective Layer, new data on stable isotope composition of S, O and H were obtained.
This complemented the high degree of homogeneity, especially in personal and social matters, that extended through Australia's great physical spread; it was expressed primarily through the Commonwealth's financial powers at first especially relating to customs and excise duties but later by direct taxation.
The 68% of the world's nuclear electricity from PWRs is thus set to increase, with other technologies trailing way behind.Developing a nuclear reactor has never been a matter for barnstorming experimentationSuch homogeneity in a 70-year-old high-technology enterprise is remarkable.
Gray matter density and regional homogeneity (ReHo) were used to map brain structure and resting-state function, respectively.
It's difficult to argue that all this Ivy League homogeneity is a bad thing.
The discovered uniformity, i.e. constancy, of the cerebral specific exponents in gray matter suggests a common principle underlying the basal metabolism of different brain structures, which might be associated with the homogeneity of synaptic density throughout the gray matter [ 28, 29].
