Genetic algorithm applied to parameter estimation of bacterial growth modeling
(Elsevier, 2016-11-14)Predictive microbiology is nowadays one of the main tools to understand microbial interactions and to assess the quantitative risk in foods. Several models have been developed in order to predict microorganism growth. The ... -
Genetic differentiation within and away from the chromosomal rearrangements characterising hybridising chromosomal races of the western house mouse (Mus musculus domesticus)
(Springer, 2016-04-05)The importance of chromosomal rearrangements for speciation can be inferred from studies of genetic exchange between hybridising chromosomal races within species. Reduced fertility or recombination suppression in karyotypic ... -
