ON ZERO-SUM SEQUENCES IN Z/nZ⊕ Z/nZ

It is well known that the maximal possible length of a minimal zero-sum sequence S in the group Z/nZ⊕Z/nZ equals 2n−1, and we investigate the structure of such sequences. We say that some integer n ≥ 2 has Property B, if every minimal zero-sum sequence S in Z/nZ⊕Z/nZ with length 2n− 1 contains some element with multiplicity n− 1. If some n ≥ 2 has Property B, then the structure of such sequence...

Although plant roots take up nitrogen (N) both as ammonium (NH 4 ) and nitrate (NO 3 ) ions, under most soil conditions uptake of NO 3 dominates. Once absorbed by the plant roots, the NO 3 is reduced to NH 4 , which is subsequently assimilated into organic compounds. However, when the ra te of uptake exceeds the rate of NO 3 reduction, accumulation of NO 3 in plants occurs. Ruminant animals wit...

Explorer Hippocampus at 25

Hippocampus at 25.

The journal Hippocampus has passed the milestone of 25 years of publications on the topic of a highly studied brain structure, and its closely associated brain areas. In a recent celebration of this event, a Boston memory group invited 16 speakers to address the question of progress in understanding the hippocampus that has been achieved. Here we present a summary of these talks organized as pr...
