Query: On Adjacency Matrices and Descriptors of Signed Cycle Graphs   This paper deals with adjacency matrices of signed cycle graphs and chemical
descriptors based on them. The eigenvalues and eigenvectors of the matrices are
calculated and their efficacy in classifying different signed cycles is
determined. The efficacy of some numerical indices is also examined.
