Hesse and the Jacobian Conjecture

In this paper we give a survey of various recent results obtained by the authors in the study of the Jacobian Conjecture. It is shown that it suffices to investigate the conjecture for polynomial maps of the form x+H with JH nilpotent and symmetric (and one may even assume that H is homogeneous of degree 3). Furthermore it is shown that for such maps the Jacobian Conjecture is true if n ≤ 4 and...

The Hesse Simulation Environment

on oz - o - Mannosyl Residues BY KAREN

The murine major histocompatibility complex I-J subregion has recently been the subject of much controversy. The Ia-4 locus within I-J encodes a suppressor T lymphocyte surface marker (1), as well as a suppressor T cell factor determinant (2). Using recombinant strain distribution patterns, independent investigators mapped I-J between I-B and I-B and I-E, in the chromosomal segment bounded by r...

got a lot to offer in the way of anatomical sophistication — they are essentially a hollow bag of cells with one opening and tentacles on one side — but they are of great interest for their position in the tree of life. Cnidarians are considered a branch that separated early from the bilaterally symmetric animals. So, comparing the two groups should allow inferences about their common ancestors...
