We review the Turing and Oster-Murraym models of biological morphogenesis. From the latter we apply primary mechanisms of extracellular-matrix (ECM) deformation, cell mitosis, cell diffusion and ECM-cell interaction to a model of biological growth, and derive the principal modes of mass flux from the linear eigenmodes of each mechanism. The assumption of uniform mass distribution means that the eigenmodes are the same for elastic, diffusive and convective modes.

We derive a metric of biological growth using the Gompertz function and show that it can also be arrived at from a thermodynamic model of growth inhibition. This metric is to be used in 3D shape registration, and can be computed for partial local registrations using a linear sum of eigenmode projections.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
