Recently, the first author generalized a formula of Nekrasov and Okounkov which gives a combinatorial formula, in terms of hook lengths of partitions, for the coefficients of certain power series. In the course of this investigation, he conjectured that a(n) = 0 if and only if b(n) = 0, where integers a(n) and b(n) are defined by

Some of the last results on low energy antiproton physics are reviewed. First Faddeev calculations for ¯ nd scattering length are presented.

The title compound, [PtCl(2)(C(20)H(17)P)(2)], forms a monomeric cis-square-planar geometry. The Pt-P bond lengths are 2.2489 (9) and 2.2627 (9) Å, whereas the Pt-Cl bond lengths are 2.3566 (9) and 2.3336 (9) Å.

Perceived slant was measured for horizontal lines aligned on one side and of varying lengths whose length disparity was either a constant linear amount for all lines (consistent with uniocular occlusion) or proportional to line length (consistent with global slant). Although the disparity of any line was ambiguous with respect to these two possibilities, slant of individual lines did not occur ...

A general expression for the π − N and π − ∆ scattering lengths is derived in the framework of a microscopic calculation. Annihilation, negative energy wavefunctions and spontaneous chiral symmetry are included consistently. The point-like limit is used to calculate the scattering lengths.
