We give a geometric description of binary quantum stabilizer codes. In the case of distance d = 4 this leads to the notion of a quaternary quantum cap. We describe several recursive constructions for quantum caps, determine the quantum caps in PG(3, 4) and the cardinalities of quantum caps in PG(4, 4). ∗research partially supported NSA grant H98230-10-1-0159 †The research of this author takes p...

Purely non-cooperative principles, as iterated dominance and backward induction, explain divided government. CORE, Université Catholique de Louvain, Belgium.

The official screening results of the Belgian National Committee for Inherited Skeletal Disorders, an affiliate of the Belgian Kennel Club, have been used to estimate the prevalence of hip dysplasia, elbow dysplasia and humeral head osteochondrosis in the dog breeds in Belgium, and these have been compared with reported prevalence data from other countries. In some breeds, the prevalence of hip...

In this report the results of a Belgian multicenter 24-week open-label study with donepezil in the treatment of mild to moderate Alzheimer's disease are described. Efficacy and safety were evaluated in a sample of 200 patients recruited in 25 Belgian centers. No significant changes could be found in cognition and behaviour over this 6-month period. Changes in daily functioning were small. Safet...

true for the study of localization in one dimension, for which the T ' dependence of the resist3nce predicted by Thouless remains to be observed. Copper wires, with thicknesses of 100 A, widths of 1 pm, and lengths of 1 cm would seem to be well suited for that purpose. We thank the Belgian Interuniversitair Instituut voor Kernwetenschappen for financial support, and the Nuclear Research Center,...

This article investigates whether European identity is a feasible and functional alternative to national identity. We examine the extent, determinants and consequences of national and European identification among (immigrant) Turkish and native Belgian pupils, with data gathered from 1629 pupils across 68 Belgian schools. The results show that immigrant Turkish pupils identify more strongly wit...

We prove that the equivalence between Vershik’s standardness criterion and the I-cosiness criterion for a filtration in discrete, negative time, holds separately for each random variable. This gives a strengthening and a more direct proof of the global equivalence between these two criteria. We also provide more elementary original propositions on Vershik’s standardness criterion, while emphasi...

In this article, the introduction of the Wassermann Test and arsenic-based drugs in Belgian post-war venereal disease (VD) policy is discussed (for the period of 1900-1930). Pre-war advances in clinical medicine, the development of the Wassermann Test and arsenical drugs, as well as war conditions, were important in putting syphilis on the public agenda in Belgium. However, the way in which new...
