The ABC index is a topological index was defined as d ( ) d ( ) 2 ( ) d ( )d ( ) G G uv E G G ABC G u v u v ∈ + − = Σ , where d ( ) G u denotes degree of vertex u. Now we define a new version of ABC index as 4 ( ) δ ( ) δ ( ) 2 ( ) δ ( )δ ( ) G G uv E G G G ABC G u v ∈ u v + − = Σ , where ( ) ( ) d ( ) G uv E G G u v ∈ δ =Σ . The goal of this paper is further the study of the ABC4 index.

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.
