The resistance distance r(u,v) between vertices u and v of a connected (molecular) graph G is computed as the effective resistance between nodes u and v in the corresponding network constructed from G by replacing each edge of G with a unit resistor. The Kirchhoff index Kf(G) is the sum of resistance distances between all pairs of vertices. In this work, an explicit closed-form formula for Kirchhoff index of the nanostar dendrimer NS[n] is derived according to a recursive relation of resistance distances, and the Kirchhoff index of NS[n] is approximately to 7/9 of its Wiener index and 7/15 of its detour index, respectively..

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.
