Multiresolution Molecular Shapes
We introduce a multiresolution representation scheme for variable levels of detail of molecular shapes (shapes synthesized as sets of balls). In particular, we consider in our model the exact boundary computation of the the basic union of balls for CPK model and solvent accessible surface as well as the more complex rolling ball solvent contact surface and molecular skin. Our decimation/refinem...
متن کاملIntrinsic Shapes of Molecular Cloud
We conduct an analysis of the shapes of molecular cloud cores using recently compiled catalogs of observed axis ratios of individual cores mapped in ammonia or through optical selection. We apply both analytical and statistical techniques to de-project the observed axis ratios in order to determine the true distribution of cloud core shapes. We nd that neither pure oblate nor pure prolate cores...

متن کاملVisualization of Shapes of Molecular Anions *
One could expect to find a simple yet rigorous treatment of anisotropics of polyatomic ions in treatises on structural and inorganic chemistry. However, despite many discussions [1-4] of sizes, shapes and anisotropics of interactions, a unified approach to these anisotropics is, to the authors ' knowledge, conspicuous by its absence from the chemical literature. In fact, desirability of such an...
متن کاملCoiled-coil networking shapes cell molecular machinery
The highly abundant α-helical coiled-coil motif not only mediates crucial protein-protein interactions in the cell but is also an attractive scaffold in synthetic biology and material science and a potential target for disease intervention. Therefore a systematic understanding of the coiled-coil interactions (CCIs) at the organismal level would help unravel the full spectrum of the biological f...
