Analytical shape computation of macromolecules: I. Molecular area and volume through alpha shape.
The size and shape of macromolecules such as proteins and nucleic acids play an important role in their functions. Prior efforts to quantify these properties have been based on various discretization or tessellation procedures involving analytical or numerical computations. In this article, we present an analytically exact method for computing the metric properties of macromolecules based on th...

متن کاملVariations in eye volume, surface area, and shape with refractive error in young children by magnetic resonance imaging analysis.
PURPOSE To determine variations in eye volume, surface area, and shape with refractive error in young children using a three-dimensional magnetic resonance imaging (MRI) model. METHODS A subset of Singaporean Chinese boys enrolled in the population-based Strabismus, Amblyopia, and Refractive Error in Singapore (STARS) study underwent MRI using a 3-Tesla whole body scanner with a 32-channel he...
متن کاملAuto-Surface Reconstruction with Alpha Shape
In this paper, we present an algorithm for the reconstruction of piecewise linear surfaces from unorganized sample points with improved a-shape. Alpha-shapes is based on eficient, discrete mathematics which determine exact relationships between points, shapes, and spaces. It generates a family of shapes according to the selected a parameter. The method discussed in this paper might be applied f...
متن کاملSurface area and volume measurements for ram and human spermatozoa.
Surface area and volume measurements were made for ram and human spermatozoa. Measurements were made using different techniques in an attempt to confirm estimates arrived at by independent methodologies. Sperm head projected surface areas were calculated from published formulae using linear micrometry measurements or were obtained directly by image analysis. Total surface areas were calculated ...
