The phrase "a selection between two" is correct and usable in written English.
It can be used when discussing a choice or decision that involves two options or alternatives.
Example: "In this project, we have a selection between two different marketing strategies that we can implement."
Alternatives: "a choice between two" or "an option of two".
This type of behavior was found to result from variability in life due to a probabilistic selection between two mechanisms, viz.
A suitable generalized measurement described by a 4-element positive operator-valued measure (POVM) on each particle of a two-qubit system in the singlet state is, from the point of view of Einstein, Podolsky, and Rosen's (EPR's) criterion of elements of reality, equivalent to a random selection between two alternative projective measurements.
Here we show, using a stochastic simulation of selection between two hypothetical species, "R" (risk-seeking) and "A" (risk-averse) that, when expected reproductive fitness of the individual is unaffected by the making of the risky choice (winnings balanced by losses) natural selection (taken to the point of extinction) favors the risk-averse species.
Evolutionary game theory analyses the frequency dependent selection between two strategies, A and B. Inclusive fitness theory assumes a continuum of mixed strategies between A and B and then studies the direction of selection in this continuous strategy space.
In a genome-wide screen for signatures of selection, Martinez et al. (2011) found three microsatellite markers mapping to Omy5 displaying evidence of a signature of differential selection between two historically sympatric populations of migratory and resident rainbow trout.
Martinez et al. (2011) identified a single marker that maps to this chromosome, which shows marginal support of a signature of divergent selection between two closely related populations of rainbow and steelhead trout from California.
Under a scenario of divergent selection between two large populations that remain connected by moderate to high levels of gene flow (necessary to homogenize the neutral genomic background), anonymous large-effect loci associated with the adaptive divergence can be detected using standard genome-scan methods (Le Corre and Kremer 2003, 2012).
This conclusion accords with the value-based decision theorists' view that attentional selection between two rewards has a reciprocal relationship with the emergence of a preference prior to choice 15, 16.
On the other hand, the model applied in the current study, time-dependent PF model, is based on a quantitative theory for the amount of selection between two recently diverged species (Sawyer and Hartl 1992).
With this end in mind the different techniques will be applied to the selection between two CHP units for a tyre factory in Spain.
