Conjugating cyclic \(n\)-color compositions
Utilitas MathematicaMacMahon extensively studied integer compositions, including the notion of conjugation. More recently, Agarwal introduced \(n\)-color compositions and their cyclic versions were considered by Gibson, Gray, and Wang. In this paper, we develop and study a conjugation rule for cyclic \(n\)-color compositions.

Radical Cations of Conjugated Cyclic Disulfides
1990Persistent radical cations of heterocycles containing two conjugated sulfur atoms are readily detected by ESR spectroscopy. These systems are often more persistent than their acyclic analogues because scission of a sulfur-sulfur bond does not lead to irreversible decomposition.

Preparation of cyclic nucleotide antisera with thyroglobulin-cyclic nucleotide conjugates.
Journal of cyclic nucleotide research, 1981Antisera to cyclic AMP and cyclic GMP were obtained by immunizing rabbits with antigens prepared by conjugating the 2'0-succinyl derivative of the cyclic nucleotides to thyroglobulin. The cyclic nucleotide-thyroglobulin conjugates were injected intradermally into multiple sites on the backs of the animals.

Overlooked relations in the theory of cyclic conjugation
Chemical Physics Letters, 1985Abstract The four existing methods for the calculation of the effect of cyclic conjugation are examined using the μ-polynomial formalism. Two of them are shown to be identical. Another is shown to be related to theory of magnetic susceptibility.
