As for concrete without any admixture, its resistance against combined freezing-thawing and sulfate attack increased up to 125 freezing-thawing cycles and then decreased.
The FBAT statistic has an additional advantage in that it is robust against population admixture and stratification [67].
Thus, it is possible that some unique phenotypic features (e.g. size or behavior) of Italian wild aurochsen might have lessened the need by the first farmers and pastoralists to act against their admixture with domesticated stocks.
Method performance for the StepPCO procedure has already been tested against other admixture detection methods, most extensively with HAPMIX (Price et al. 2009), with favorable results.
The original StepPCO method (Pugach et al. 2011) has already been tested extensively against other admixture detection methods, particularly HAPMIX (Price et al. 2009).
Since the C3* Y chromosomes are present in the Ecuadorian populations at moderate frequency, the absence of evidence for >1% recent admixture is strong evidence against their recent introduction into Ecuador.
The findings strongly endorse that bagasse ash when used as a supplementary cementing admixture, imparts resistance to concrete against elevated temperatures.
The average length of shared haplotypes between Ahuacatitlan and mexicana (mean 4.8 cM) was, however, shorter than the average length of haplotypes shared among mexicana populations (mean 30.7 cM), arguing against extensive recent admixture.
For a focal African genome within a particular window, the method compares this genome against a cosmopolitan reference panel and assesses whether its genetic distance to this reference panel is on the level expected for a sub-Saharan genome or if instead this resembles a comparison of one cosmopolitan genome against others (indicating admixture).
We do not believe that we have ever encountered such a false-positive admixture signal, but to guard against it, we note that if it were to occur, the three decay time constants for the reference pairs A′– B′, A′– C, and B′– C would disagree.
