Introduction. I would like to begin by stating a conjecture. While I am not convinced of the truth of this statement, I think it is useful to crystallize one's ideas, and to have a particular problemâ€¦ (More)

Gorenstein liaison seems to be the natural notion to generalize to higher codimension the well-known results about liaison of varieties of codimension 2 in projective space. In this paper we studyâ€¦ (More)

A procedure is described for purification of the sodium channel 1380-fold from rat brain to essential homogeneity. The channel is solubilized in Triton X-100 and stabilized by addition ofâ€¦ (More)

We extend the theory of generalized divisors so as to work on any scheme X satisfying the condition S2 of Serre. We define a generalized notion of Gorenstein biliaison for schemes in projectiveâ€¦ (More)

We characterize the postulation character of arithmetically Gorenstein curves in P 4. We give conditions under which the curve can be realized in the form mH âˆ’K on some ACM surface. Finally, weâ€¦ (More)

Let X be an integral projective scheme satisfying the condition S3 of Serre and H(OX(n)) = 0 for all n âˆˆ Z. We generalize Raoâ€™s theorem by showing that biliaison equivalence classes of codimensionâ€¦ (More)

The saxitoxin receptor of the sodium channel purified from rat bran contains three types of subunits: alpha with Mr approximately 270,000, beta 1 with Mr approximately 39,000, and beta 2 with Mrâ€¦ (More)

Single channel currents of sodium channels purified from rat brain and reconstituted into planar lipid bilayers were recorded. The kinetics of channel gating were investigated in the presence ofâ€¦ (More)
