i.e., two cereal crops per year) requires inputs of synthetic agrichemicals and irrigation in food production, causing large greenhouse gas (GHG) emissions; in contrast, rotation systems diversified with cash and legume crops can maintain crop yields, increase farmers...

Diversifying selectionis tested by looking at rates of non-synonymous (Ka) versus synonymous (Ks) nucleotide substitutions. Non-synonymous substitutions, where anamino acidis substituted, can reduce or remove function, and are therefore presumed to be biologically detrimental. The Ka:Ks ratio is ther...
Reversals and the high fluctuations observed in the weights occur less frequently with more realistic rebalancing strategies. By rebalancing the portfolio daily, the portfolio’s composition can be more quickly adjusted to new information, but it is associated with higher transaction costs and justifying...
50. After the offspring have received their alleles from their parents, a mutation can occur with a small probability mc (resp. mp) per locus. In such a case, a randomly chosen number u is added to the original allelic value, where the mutational step size u is drawn from a normal ...
Positively correlated cash flows tend to occur at the same time and in the same direction, leading to lumpy inflows and outflows as well as an increase in volatility from quarter to quarter. In contrast, uncorrelated cash flows are less likely to coincide, creating smoother, more predictable ca...
Over time, tandem gene duplication can occur as is seen in the radish Rfo region. Interestingly, this tandem duplication is not evident in Arabidopsis PPR gene distribution. PPR genes are for the most part found as singlets with PPR gene subgroup members evenly distributed in the Arabidopsis ...
Finally, for retailers, a shift in the mix is likely to occur as e-commerce continues gaining ground, especially in categories with lower cost to serve, such as beauty and personal care. Traditional trade may continue to lose share but may somewhat slow its decline by becomin...
As our goal was to find ROHs that represent autozygosity rather than simply occur by chance, this analysis was performed using the SNPs pruned for local LD (r2o0.5). In this case, the pruning was performed for each local population separately. All the above analyses were performed in PLINK...
This is another trait that altmetrics have in common with citations, which alone are not always a good indicator for impactful research; after all, citations can occur for many reasons (Cronin, 1984; Bornmann and Daniel, 2008). However, we cannot rule out the possibility that certain types...
