This paper presents a comparison of Genetic Programming(GP) with Simulated Annealing (SA) and Stochastic Iterated Rill Climbing (SIRC) based on a suite of program discovery problems which have been previously tackled only with GP. All three search algorithms employ the hierarchical variable length representation for programs brought into recent prominence with the GP paradigm [K-92]. We experim...

In Bacillus megaterium, the hemAXBCDL genes were isolated and were found to be highly similar to the genes from Bacillus subtilis that are required for the conversion of glutamyl-tRNA into uroporphyrinogen III. Overproduction and purification of HemC (porphobilinogen deaminase) and -D (uroporphyrinogen III synthase) allowed these enzymes to be used for the in vitro synthesis of uroporphyrinogen...

The aim of this study was to evaluate the possible implementation of hydrophilic polymers as recovery agents in air-damaged corneal cells. The sessile bubble technique was implemented to measure the wetting properties of four selected polymers: hydroxyethyl cellulose (HEC), sodium chondroitin sulphate (SCS), hydroxypropyl-methylcellulose (HPMC) and poloxamer F127 (PO12), at equilibrium conditio...

This paper deals with the fractional-order SIRC model associated with the evolution of influenza A disease in human population. Qualitative dynamics of the model is determined by the basic reproduction number, R0. We give a detailed analysis for the asymptotic stability of disease-free and positive fixed points. Nonstandard finite difference methods have been used to solve and simulate the syst...
