    Notes: Summary TheT-hull of both discrete point sets and continua is a generalization of the convex hull with respect to a reference objectT. VariousT-hulls serve as tools for shape analysis and as a basis for the introduction of a family of shape similarity measures. Some potential applications of these measures to shape problems arising in the natural sciences and a specific chemical example are discussed. The method ofT-hulls is applicable for the description of molecular shape effects in solvent-solute interactions, in external electromagnetic fields and within enzyme cavities.

    Keywords: Shape analysis ; Lattice animals ; Similarity ; Complexity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary An equivalence relation on square-cell configurations, which we call animals, is formulated precisely, using the similarity criterion of “seeing” parts of the shape of the animal from its interior, and an operation called “squashing”, leading to a smaller animal. It is noted that there is a unique smallest animal in each resulting equivalence class, called the canonical animal of its class. It is proposed that the number of cells in a canonical animalA serves as a measure of complexity of any animal similar toA. The formulation of the canonical animal is suggested as a tool for characterizing shapes of monolayer clusters of adsorbed molecules on square lattices, a problem of importance in chemical catalysis.

    Topics: Chemistry and Pharmacology
    Notes: Abstract Macromolecular shape analysis, an important aspect of the interpretation and prediction of biochemical behavior, pharmaceutical drug action, and the properties of advanced materials, is a task of a high level of complexity, where both global shape features and detailed, local shape features are relevant. The methods developed for the study of shapes of small molecules, in terms of molecular isodensity contours (MIDCOs), are not ideally suited for large molecular systems. In particular, the shape analysis of ab initio quality macromolecular electron densities, obtained by the MEDLA (molecular electron density lego assembler) method, requires a new approach. In this contribution, the adaptation of the earlier shape group approach to the electron densities of large molecules, and two new techniques, the shape globe folding map and the self-avoiding MIDCO methods, will be described.
