The possible application of the combination of horseradish peroxidase (HRP) and Lucifer Yellow CH (LY) for differential retrograde labelling of a relatively large invertebrate nervous system requiring the enzymatic marker to be processed after fixation and sectioning was evaluated. In control experiments an HRP fluorescence induced by glutaraldehyde (GA)(More)
1. Introduction Molecular beam epitaxy has become an important tool to prepare ultrathin films and nanostructures in nonequilibrium states that show novel properties distinctly different from the equilibrium bulk phases. Theoretically, the question arises how to relate the structural characteristics of the growing material to the incoming flux and(More)
We present an extension of the density-functional theory (DFT) formalism for lattice gases to systems with internal degrees of freedom. In order to test approximations commonly used in DFT approaches, we investigate the statics and dynamics of occupation (density) profiles in the one-dimensional Potts model. In particular, by taking the exact functional for(More)
