The newly developed topological indices Am1, Am2, and Am3 were applied to multivariate analysis in structure–property correlation studies. In this paper the topological indices Am1, Am2 and Am3 of C4C8(S) nanotori are estimated with high accuracy by approximating functions f ( p, q) i , i = 1,2,3 , where p and q represent the number of polyhexs in one row and the number of rows in the nanotorus respectively. These functions are obtained using numerical analysis approach. The predictive ability of suggested functions are evaluated according to their Sum of Residuals Squared (SSE) and Coefficient of Determination (r2)..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
