A complete classification of the perfect binary one-error-correcting codes of length 15 as well as their extensions of length 16 is presented. There are 5 983 such inequivalent perfect codes and 2 165 extended perfect codes. Efficient generation of these codes relies on the recent classification of Steiner quadruple systems of order 16. Utilizing a result of Blackmore, the optimal binary one-er...

On the occasion of quality controls in food business and during official food surveillance, didecyldimethylammonium chloride (DDAC) residues in excess of the currently applicable maximum residue level (MRL) of 0.01 mg/kg were detected in food. The first opinion on DDAC residues, which was issued by the Federal Institute for Risk Assessment (BfR) on 29 June 2012 (BfR opinion No 024/2012, availab...

We present low resolution optical spectroscopy for six cataclysmic variable candidates and the old nova V888Cen. We confirm the classification as cataclysmic variable for LB 9963 and FQMon, while the other four candidates turn out to be different type of stars. We discuss the individual spectra and pay special attention to the mass transfer rate and disc temperature and density of the three cat...
