Let M be a d× d real contracting matrix. In this paper we consider the selfaffine iterated function system {Mv − u,Mv + u}, where u is a cyclic vector. Our main result is as follows: if | detM | ≥ 2−1/d, then the attractor AM has non-empty interior. We also consider the set UM of points in AM which have a unique address. We show that unless M belongs to a very special (non-generic) class, the H...

The formation of complexes between actinomycin (AM) (Fig. 1) and DNA is known to depend on specific structures in both the antibiotic and the polydeoxynucleotide.' These include the base guanine in the helical conformation of DNA, and the amino group, the quinoidal oxygen, and the intact peptide lactones of the antibiotic. A model for the structure of AM-DNA complexes which accounts for the par...

unique opportunity to study the poorly-known Bs meson. Three analyses, using a sample of 23.6 fb−1, are presented. We report the first observation of the three dominant exclusive Bs decays, Bs → D∗− s π+, Bs → Ds ρ+ and Bs → D∗− s ρ+, the first observation of the CP-eigenstate decay Bs → J/ψ η , and the results from a study of the charmless Bs → K+K−, Bs → K+π−, Bs → π+π− and Bs → K0 S K0 S dec...

We present recent diboson production measurements from the D0 experiment at Fermilab's Teva-tron collider. The production of ZZ was observed using leptonic final states. Zγ → ννγ was observed and used to set the most stringent limits from a hadron collider on anomalous Zγγ and ZZγ trilinear gauge couplings (TGCs). WW events with leptonic final states and WW +W Z events with semi-leptonic final ...
