Genes encoding resistance to stressors, such as antibiotics or environmental pollutants, are widespread across microbiomes, often encoded on mobile genetic elements. Yet despite their prevalence, the impact of resistance genes and their mobility upon

Feeding cattle with on-pasture supplementation or feedlot diets can increase animal efficiency and system profitability while minimizing environmental impacts. However, cattle system profit margins are relatively small and nutrient supply accounts fo

We present a parallelization of the revised simplex method for large deterministic-equivalent forms of stochastic linear programming (LP) problems. These problems have been considered too large to solve using the simplex method, and instead, decompos
