In three mouse lineages it was found that during the 18- to 60-day interval after formalin fixation, brain weight was inversely proportional to the age at sacrifice, as was the decline in the weight of the brain during this period. In a second study using rat subjects it was confirmed that the aging difference is due to a reduction, in old age, of the(More)
This paper establishes the equivalence of four de nitions of two vector valued functions being rearrangements, and gives a characterisation of the set of rearrangements of a prescribed function. The theory of monotone rearrangement of a vector valued function is used to show the existence and uniqueness of the minimiser of an energy functional arising from(More)
