    Evolution of host–parasitoid network through homeochaotic dynamics (1992)

    Notes: Host–parasitoid systems with evolving mutation rates are studied. By increasing the growth rate of hosts, the diversity of both species is maintained dynamically. For the lower growth rate, diversity is brought about by mere parasitism. The average mutation rate for parasites is elevated to a high value, while that for hosts is suppressed at a low level. For the higher growth rate, the mutation rates for both hosts and parasites are elevated to form a symbiotic cluster connected by on-going mutation. This symbiotic state is sustained through a chaotic oscillation keeping some coherency among species. For a flat landscape for hosts, dynamical clustering of oscillation is observed. Lyapunov spectra of such oscillations show that high dimensional chaos with small positive exponents underlies in the symbiotic state. This weak high dimensional chaos, termed "homeochaos,'' is essential to the maintenance of symbiosis in ecosystems.

    Evolvability of machines and tapes (1999)
    Springer
    Artificial life and robotics 3 (1999), S. 242-245

    ISSN: 1614-7456

    Topics: Computer Science
    Notes: Abstract A self-reproduction process is described and discussed via a network model of machines and description tapes. The emergence of a core network which dynamically sustains the rewriting processes of machines on tapes is reported. The structures of the core networks are generic, and include Eigen's hypercycle as a special case. In the cell assembly model, where each cell contains machines and tapes, we show that the instability of the core network in some cells is sustained by those cells with stable core networks. The instability of the core network is transfered to its offspring when the cells divide. What is inherited here is not the patterns of tapes, but the way machines read tapes in a core network.

    Detection of Polyols by HPLC Coupled with an On-Line Photochemical Oxidation Reactor and Chemiluminescence Detection (2000)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 23 (2000), S. 127-130 
    Details
    ISSN: 0935-6304

    Topics: Chemistry and Pharmacology
    Notes: ---In this paper we propose a new post-column detection method for polyols containing 1,2-diol, 1,3-diol, and saccharides. The polyols are oxidized in a photochemical reactor to yield oxalate with subsequent chemiluminescence detection using [Ru(III)(bpy)3]3+. A mixing solution of eluate and oxidizing reagent is delivered to a reaction coil, which is then irradiated with ultraviolet light to promote the oxidation reaction. The detection limits for 1,2-ethanediol (ethylene glycol) and 1,3-propanediol were 38 pmol and 23 pmol, respectively.
