A graph Γ=(V,E) of order n is distance magic if it admits a bijective labeling ℓ:V→{1,2,…,n} its vertices for which there exists positive integer κ such that ∑u∈N(v)ℓ(u)=κ all v∈V, where N(v) the neighborhood v. circulant admitting an automorphism cyclically permuting vertices. In this paper we study circulants valency 6. We obtain some necessary and sufficient conditions 6 to be magic, thereby...

Residues important in the interaction between the 23-residue transmembrane (TM) domains of the integrin alpha(IIb)- and beta(3)-subunits were identified by mutating each non-Leu residue to Leu. Leu substitutions of alpha(IIb) at G972, G976, and T981, and of beta(3) at I693 and G708, increased ligand binding. Substitutions with other amino acids at alpha(IIb)G972 and beta(3)G708 could also incre...
