Constructive counterexamples to additivity of minimum output R\'enyi entropy of quantum channels for all p>2

We present a constructive example of violation of additivity of minimum output R\'enyi entropy for each p>2. The example is provided by antisymmetric subspace of a suitable dimension. We discuss possibility of extension of the result to go beyond p>2 and obtain additivity for p=0 for a class of entanglement breaking channels.Comment: 4 pages; a reference adde

Lattic path proofs of extended Bressoud-Wei and Koike skew Schur function identities

Our recent paper provides extensions to two classical determinantal results of Bressoud and Wei, and of Koike. The proofs in that paper were algebraic. The present paper contains combinatorial lattice path proofs

Shaping the future for primary care education and training project. Finding the evidence for education & training to deliver integrated health and social care: the primary care workforce perspective

This report is one of a series of outputs from the Shaping the Future in Primary Care Education and Training project (www.pcet.org.uk) funded by the North West Development Agency (NWDA). It is the result of a collaborative initiative between the NWDA, the North West Universities Association and seven Higher Education Institutions in the North West of England. The report presents an evidence base drawn from the analysis of the experiences and aspirations of integrated health and social care, as reported by members of the current primary health and social care workforce working in or with Primary Care Trusts (PCTs) in the North West region

Improved molybdenum disulfide-silver motor brushes have extended life

Motor brushes of proper quantities of molybdenum disulfide and copper or silver are manufactured by sintering techniques. Graphite molds are used. These brushes operate satisfactorily for long periods in normal atmosphere or in a high-vacuum environment
