Soils at the ground surface experience multiple cycles of drying and wetting. On drying, soils shrinkage cracks may appear. The development depends on tensile strength soil. Such increase permeability soil can cause slopes earth structures to fail due rainfall. Several models have been proposed for unsaturated considering effect matric suction. However, are either cohesionless (coarse-grained) ...

Assessing the influence of three-dimensional protein structure on sequence evolution is a difficult task, mainly because of the assumption of independence between sites required by probabilistic phylogenetic methods. Recently, models that include an explicit treatment of protein structure and site interdependencies have been developed: a statistical potential (an energy-like scoring system for ...

The fine-grained nature of the HPSG representations found in the Redwoods treebank raises novel issues in parse disambiguation relative to more traditional treebanks such as the Penn treebank, which have been the focus of most past work on probabilistic parsing (e.g., Charniak 1997; Collins 1997). The Redwoods treebank is much richer in the representations it makes available. Most similar to Pe...
