Transition metal clusters on graphite

The topic of this work is 3d transition metals deposited on graphite. Spin-polarised density-functional calculations are used to obtain the magnetic moments of deposited adatoms and dimers. Interatomic potentials are also deduced. These are used in molecular dynamics simulations to study cluster formation and to investigate cluster morphology.

Individual assets, market structure and the drivers of return

Much prior research on the structure and performance of UK real estate portfolios has relied on aggregated measures for sector and region. For these groupings to have validity, the performance of individual properties within each group should be similar. This paper analyses a sample of 1,200 properties using multiple discriminant analysis and cluster analysis techniques. It is shown that conventional property type and spatial classifications do not capture the variation in return behaviour at the individual building level. The major feature is heterogeneity - but there may be distinctions between growth and income properties and between single and multi-let properties that could help refine portfolio structures.
