Effect Of Age

This study investigated the optimal structure of a closed ewe and wether flock producing wool and meat. A range of price-weighted (net of a fixed set of costs) combinations of these products was considered, and optimal structures determined for each. The aim of the study was to throw some light on the effects of the main biological factors-age, sex and fertility-on flock structure (given that there is no nutritional stress). The general conclusions were that the optimal structure shifts from disposing of wethers as lambs and ewes as 5.5-year olds to disposing of wethers as 3.5-year olds and ewes as 4.5-year olds, as fertility declines or meat declines in value relative to wool. However, the former structure tends to dominate and is optimal over a wide range of conditions.

Lattice Protein Models

AbstractLattice protein models are well-studied abstractions of globular proteins. By discretizing the structure space and simplifying the energy model over regular proteins, they enable detailed studies of protein structure formation and evolution. However, even in the simplest lattice protein models, the prediction of optimal structures is computationally difficult. Therefore, often, heuristic approaches are applied to find such conformations. Commonly, heuristic methods find only locally optimal solutions. Nevertheless, there exist methods that guarantee to predict globally optimal structures. Currently, only one such exact approach is publicly available, namely the constraint-based protein structure prediction method and variants. Here, we review exact approaches and derived methods. We discuss fundamental concepts like hydrophobic core construction and their use in optimal structure prediction, as well as possible applications like combinations of different energy models.
