Characterization of Reticulate Networks Based on the Coalescent with Recombination

Phylogenetic networks aim to represent the evolutionary history of taxa. Within these, reticulate networks are explicitly able to accommodate evolutionary events like recombination, hybridization, or lateral gene transfer. Although several metrics exist to compare phylogenetic networks, they make several assumptions regarding the nature of the networks that are not likely to be fulfilled by the evolutionary process. In order to characterize the potential disagreement between the algorithms and the biology, we have used the coalescent with recombination to build the type of networks produced by reticulate evolution and classified them as regular, tree sibling, tree child, or galled trees. We show that, as expected, the complexity of these reticulate networks is a function of the population recombination rate. At small recombination rates, most of the networks produced are already more complex than regular or tree sibling networks, whereas with moderate and large recombination rates, no network fit into any of the standard classes. We conclude that new metrics still need to be devised in order to properly compare two phylogenetic networks that have arisen from reticulating evolutionary process

The Effect of Tumbling, Sodium Chloride and Polyphosphates on the Microstructure and Appearance of Whole-Muscle Processed Meats

The properties of a whole-muscle processed meat were determined. The complex action of socium chloride, polyphosphates and mechanical agitation caused extraction of myofibrillar protein, swelling of fibers and loss of cross-strations. A new functional ability was found for the extracted proteins to form a fine cover or membrane on the surface of the whole muscle during cooking. These changes produced a product with improved cooking yield and color appearance

State Legislative Update

The purpose of this Bill is to provide an alternative approach for individuals with a cause of action against a municipality.\u27 Rather than the costly and time-consuming traditional method of hiring an attorney and filing a lawsuit, House Bill 2631 offers individuals an opportunity for Alternative Dispute Resolution ( ADR ) in the form of arbitration. The Bill would allow any individual with a claim in contract or tort against a municipality to require the municipality to submit to the arbitration of the claim. The purpose of House Bill 2631 is to facilitate the resolution of individual claims against a city. However, a fundamental principle of arbitration is that it is a matter of contract, and no party should be forced into the arbitration of a claim which they have not agreed to arbitrate
