A model for the structure of nucleoprotamine
Journal of Ultrastructure Research, 1979A model for the structure of nucleoprotamine is presented, based on dark-field and bright-field electron micrographs of complexes of fish protamine and λDNA reconstituted in vitro . It is proposed that the protamine molecule, an ellipsoidal molecule with a comb- or star-shaped appearance, acts as a core around which the DNA double helix is wound or ...

Protein Structure Modeling with MODELLER
2008Genome sequencing projects have resulted in a rapid increase in the number of known protein sequences. In contrast, only about one-hundredth of these sequences have been characterized using experimental structure determination methods. Computational protein structure modeling techniques have the potential to bridge this sequence-structure gap.

Shape description and recognition is an important and interesting problem in scene analysis. Our approach to shape description is a formal model of a shape consisting of a set of primitives, their properties, and their interrelationships. The primitives are the simple parts and intrusions of the shape which can be derived through the graph-theoretic ...

Modeling the structure of the ribosome
Biochemistry and Cell Biology, 1995Considering the size and complexity of the ribosome and the growing body of data from a wide range of experiments on ribosomal structure, it is becoming increasingly important to develop tools that facilitate the development of reliable models for the ribosome.

The Structure of Structured Bond Portfolio Models
Operations Research, 1992Over the past decade, optimization models have been widely used to help select bond portfolios. Several different formulations are popular. The purposes of this paper are to clarify the basic structures of the models, to explain the relationships among them, and to assess their strengths and weaknesses.

Structure prediction and modelling
Current Opinion in Biotechnology, 1991Protein structure prediction from sequence remains a major goal in molecular biology. The methods described in this review concentrate on deriving structural information through the detection of similarities between a test sequence and a database of known structures. Such methods are often referred to as knowledge-based strategies reflecting the use of

For a molecule of biological importance, one expects a strong correlation between the three-dimensional structure and its biological function(s). Molecular simulations allow the prediction of physical properties of macromolecules. Many of these properties are closely related to the molecular structure.

The mathematical treatment of three models of possible development of a society with a dominance relationship is discussed. The conclusion is reached that social factors as well as inherent characteristics need to be introduced to account for near-hierarchical structures.
