On Waring's problem: two squares and three biquadrates
We investigate sums of mixed powers involving two squares and three
biquadrates. In particular, subject to the truth of the Generalised Riemann
Hypothesis and the Elliott-Halberstam Conjecture, we show that all large
natural numbers n with 8 not dividing n, n not congruent to 2 modulo 3, and n
not congruent to 14 modulo 16, are the sum of 2 squares and 3 biquadrates.Comment: to appear in Mathematik

Products in Residue Classes
We consider a problem of P. Erdos, A. M. Odlyzko and A. Sarkozy about the
representation of residue classes modulo m by products of two not too large
primes. While it seems that even the Extended Riemann Hypothesis is not
powerful enough to achieve the expected results, here we obtain some
unconditional results ``on average'' over moduli m and residue classes modulo m
and somewhat stronger results when the average is restricted to prime moduli m
= p. We also consider the analogous question wherein the primes are replaced by
easier sequences so, quite naturally, we obtain much stronger results.Comment: 18 page

Comparative Analysis of the Major Polypeptides from Liver Gap Junctions and Lens Fiber Junctions
Gap junctions from rat liver and fiber junctions from bovine lens have similar septilaminar profiles when examined by thin-section electron microscopy and differ only slightly with respect to the packing of intramembrane particles in freeze-fracture images. These similarities have often led to lens fiber junctions being referred to as gap junctions. Junctions from both sources were isolated as enriched subcellular fractions and their major polypeptide components compared biochemically and immunochemically. The major liver gap junction polypeptide has an apparent molecular weight of 27,000, while a 25,000-dalton polypeptide is the major component of lens fiber junctions. The two polypeptides are not homologous when compared by partial peptide mapping in SDS. In addition, there is not detectable antigenic similarity between the two polypeptides by immunochemical criteria using antibodies to the 25,000-dalton lens fiber junction polypeptide. Thus, in spite of the ultrastructural similarities, the gap junction and the lens fiber junction are comprised of distinctly different polypeptides, suggesting that the lens fiber junction contains a unique gene product and potentially different physiological properties
