    Phase diagrams for a model of a lipid monolayer (1988)
    Springer
    European biophysics journal 16 (1988), S. 39-44 
    Details
    ISSN: 1432-1017
    Keywords: Lipid monolayers ; phase transitions ; Ising model

    Topics: Biology , Physics
    Notes: Abstract A microscopic model of a lipid monolayer is proposed. It includes, within a single scheme, the following factors which are considered to be essential in phase transitions in lipid systems: formation of gauche rotamers, interactions between polar heads, interactions between hydrocarbon chains (depending on their conformation) and changes in the energy of the system due to a directional ordering of the chains. Phase diagrams are constructed and discussed and it is shown how the phase diagrams are modified by alterations of these parameters and the length of the hydrocarbon chains.

    Model of population evolution with and without eugenics (1999)
    Springer
    The European physical journal 11 (1999), S. 687-690 
    Details
    ISSN: 1434-6036
    Keywords: PACS. 87.10.+e General theory and mathematical aspects - 02.70.Lq Monte-Carlo and statistical methods
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract: We propose, and solve via Monte-Carlo simulation, a model describing evolution of population subject to harmful mutations. The habitat changes periodically. The evolution of two, initially identical, populations is compared. One without any external ingerence and the second in which we eliminate all individuals which are ill-fitted to the changed environment (eugenics). We show that although in the short run the individuals in the latter are better adapted and live longer, after some more changes of the environment, the populations with eugenics become extinct, while the others live on.
