Sentence examples for optima form from inspiring English sources

Hence, heuristic algorithms that search local regions of a feasible solution space detecting local optima form important components of metaheuristic methods.

Mating durations exceeding female optima serve males as a form of 'extended mate guarding': by inducing mating refractoriness in the female, a male extends the time over which its sperm is exclusively used to sire progeny and reduces the likelihood of the female being reinseminated by a competitor.

It was shown that this shortfall was comprised of a difference in the pH optima of the two biocatalyst forms and mass transfer limitations of the reactant and/or product across the cell barrier.

The focus of this work is on the design of new urban forms but the method could equally be applied to examine the relative efficiency of existing urban settlements, by comparison of existing forms with the calculated optima derived from relevant specifications of the building envelope.

Optimisation of biomass partitioning is thought to minimise the stress imposed by the limiting resource, in this case N. Arguably, such optima must depend on the actual chemical form(s) of N present for uptake, because plant N acquisition is mainly limited by processes through which N sources come into contact with root surfaces: mass flow induced by transpiration, diffusion and interception [26].

It is concluded that in lung tumour and in normal lung tissue, cath B activity can be divided into at least three fractions with stability optima at different pH values, indicating various forms of cath B. The cath B fraction active at pH 7.5 provides prognostic information in patients with squamous cell carcinoma.

Temperature optima of pectinase, xylanase and cellulase in free form and in CLEA were studied over the range of 25 70°C.

Of particular relevance, differences in symbiont thermal optima are conferred to the host in the form of resistance or susceptibility to coral bleaching [ 3, 5, 6], a condition responsible for several large-scale episodes of coral mortality [ 7- 9].

This must be regarded as a limitation, as reasonably strong hydrogen bonds could most certainly be formed at directions that deviate from these optima.

For one of the optima, we constrain τ to be unchanging in response to perturbation, forming a reference point against which we can compare the response of δ when τ is not constrained.

Thus, sperm number per ejaculate and sperm size form two important components affecting post-mating fertilization success, with potentially differing fitness optima and developmental constraints that depend on the details of the regime of sperm competition.
