The stone is prolate, obovoid in lateral view with a keel in the plane of bisymmetry and is essentially unilocular although a collapsed second locule is visible in cross section (Fig.
4i, j) with a keel in the plane of bisymmetry. It is unilocular, and lacks germination pores, valves, or opercula.
7a, c-e) is on the ventral side of the stone, bisected by the plane of fruit bisymmetry (Fig.
7i-p, t) has unilocular endocarps similar in shape and bisymmetry to those of C.
Furthermore, [B.sub.q] = -[B.sub.-q] due to the form of the RHS vector and the bisymmetry of the inverse matrix.
The justification for studying quasi-sum production functions is that these functions appear as solutions of the general bisymmetry equation and they are related to the problem of consistent aggregation (see [1]).

(This review will confine the discussion to the ceramic work although Miller's obsession with cellular patterning and bisymmetry is consistent throughout all of the work on view.) The exhibition's name alludes, in part, to the orderly and, at times, claustrophobic, close packed forms that define the surface of Miller's supersize functional ware.
A straight, thick longitudinal rib runs along the axis of bisymmetry on both faces of the fruit.
The locule is also cordate in outline, somewhat inflated, bisected by the septum and a strong vein continuous with the pedicel and style, in the plane of bisymmetry. An elliptical ovule is pendulous from the apex of each locule.
A median vein extends along the axis of bisymmetry and over the seed cavity.
Her upright forms sometimes have quite abrupt changes of contour and many of her vessels, inspired by seed forms, are given bisymmetry by means of vertical grooves or deep dimples.
