✦ Synopsis

Three inferential morphometric methods, Euclidean distance matrix analysis (EDMA), Bookstein's edge-matching method (EMM), and the Procrustes method, were applied to facial landmark data. A Monte Carlo simulation was conducted with three sample sizes, ranging from n = 10 to 50, to assess type I error rates and the power of the tests to detect group differences for two-and three-dimensional representations of forms. Type I error rates for EMM were at or below nominal levels in both two and three dimensions. Procrustes in 2D and EDMA in 2D and 3D produced inflated

The thermodynamics of molecular recognition is investigated by a statistical energy landscape approach, where the temperature profile of the ligand᎐protein binding process is determined using the weighted histogram analysis method. The analysis reveals differences in the binding energy landscapes of
