    Fractal growth of copper electrodeposits (1984)
    [s.l.] : Nature Publishing Group
    Nature 309 (1984), S. 225-229 
    Details
    ISSN: 1476-4687

    Notes: [Auszug] Black dendritic growths of copper were electrodeposited in steady-state diffusion-limited conditions onto an initially point-like cathode. Their spatial extent R was inferred from the increased current and their mass M from the total charge transferred. Fractal behaviour M∝RD ...

    Optimization strategies gleaned from biological evolution (1985)
    [s.l.] : Nature Publishing Group
    Nature 317 (1985), S. 804-806 
    Details
    ISSN: 1476-4687

    Notes: [Auszug] During the course of evolution, slowly evolving genes would have been overtaken by genes with better evolutionary strategies. Consequently, one expects highly efficient strategies in modern flora and fauna. Our purpose here is not to model biological evolution, but to attempt to glean useful ...

    Correction to the formula for the London moment of a rotating superconductor (1982)
    Springer
    Journal of low temperature physics 49 (1982), S. 1-17

    Notes: Abstract This paper gives a full quantum mechanical analysis of the magnetic field (first discussed by London) that appears spontaneously when a sample of superconductor is set into rotation. It is shown that, for slow rotation velocities and using certain approximations, the fieldB threading a cavity within a superconductor that rotates at angular velocityω is given bye B=2(m o−W/c 2)ω, where — e is the charge on the electron,m o is the free electron mass,W is the work function of the superconductor, andc is the velocity of light. In this calculation effects that are second order in the rotation velocity have been ignored, and the result is only strictly valid at the zero of temperature. The application of this result to experiments using practical, nonideal apparatus is then illustrated for a simple geometry.
