Awareness of quality assurance procedures in digital preservation

Awareness and implementation of appropriate quality assurance procedures at each stage in the process of digital preservation is vital for achieving the goals of long-term access and integrity of electronic information, and maximising the return on the high levels of investment being made in digital preservation. This paper outlines the four stages of quality assurance within the digitisation process suggested in the UK by the JISC QA Focus, and identifies issues to be considered at each stage

Multi-excitons in self-assembled InAs/GaAs quantum dots: A pseudopotential, many-body approach

We use a many-body, atomistic empirical pseudopotential approach to predict the multi-exciton emission spectrum of a lens shaped InAs/GaAs self-assembled quantum dot. We discuss the effects of (i) The direct Coulomb energies, including the differences of electron and hole wavefunctions, (ii) the exchange Coulomb energies and (iii) correlation energies given by a configuration interaction calculation. Emission from the groundstate of the $N$ exciton system to the $N-1$ exciton system involving $e_0\to h_0$ and $e_1\to h_1$ recombinations are discussed. A comparison with a simpler single-band, effective mass approach is presented
