The Swimming of Nymphon Gracile (pycnogonida)

Most arthropods move by means of metachronal waves of activity passing over the paired appendages, and the resulting gaits have been studied extensively, with regard both to their locomotory effectiveness (Manton, 1953) and to co-ordination (Beth6, 1930; von Hoist, 1935). Most attention has been focused on terrestrial or benthic arthropods and the mechanism of co-ordination of insect walking es...

Generalized Slater and Static Polarizabilities

We present applications of the recently introduced “Generalized SIC-Slater” scheme which provides a simple Self-Interaction Correction approximation in the framework of the Optimized Effective Potential. We focus on the computation of static polarizabilities which are known to constitute stringent tests for Density Functional Theory. We apply the new method to model H4 chains, but also to more ...

Transferable relativistic Dirac-Slater pseudopotentials

We present a method for constructing a scalar-relativistic pseudopotential that provides exact agreement with relativistic Dirac-Slater all-electron eigenvalues at the reference configuration. All-electron wave functions are self-consistently computed in the valence region at the exact all-electron scalar relativistic eigenvalues. This method improves transferability of the resulting pseudopote...

Hartley Slater and False Contradictions

In this note I say a few words about my interaction with the late Hartley Slater and his work. Si on appelle un chat un chat Cela évite les embrouilles Et on retombe toujours sur ses pattes Baron de Chambourcy 1 From Los Angeles to Helsinki: 20 years of friendship Barry Hartley Slater recently died (July 8, 2016). We are publishing in this issue of the South American Journal of Logic the paper ...
