In this paper we study the maximal absolute values of determinants and subdeterminants of ±1 matrices, especially Hadamard matrices. It is conjectured that the determinants of ±1 matrices of order n can have only the values k • p, where p is specified from an appropriate procedure. This conjecture i

Let M m,n (0, 1) denote the set of all m × n (0, 1)-matrices and let In this paper we exhibit some new formulas for G(m, n) where n ≡ -1 (mod 4). Specifically, for m = nt + r where 0 r < n, we show that for all sufficiently large t, G(nt + r, n) is a polynomial in t of degree n that depends on the

## Abstract Alterations of cell cycle regulatory proteins, especially those that regulate G1 to S transition, have been implicated in the pathogenesis of a wide variety of human tumors. In previous studies we showed that that there is overexpression of cyclin D1 protein predominately in the giant c

The frequent occurrence of 21q deletions in human non-small cell lung carcinoma (NSCLC) indicates the presence of a tumor suppressor gene on this chromosome arm. Since the ANA (Abundant in Neuroepithelium Area) gene, a member of an antiproliferative gene family, was mapped to 21q11.2-q21.1, we searc
