Sphere to Spheroid Comparisons

Transient cavities and the excess chemical potentials of hard-spheroid solutes in dipolar hard-sphere solvents.

Monte Carlo computer simulations are used to study transient cavities and the solvation of hard-spheroid solutes in dipolar hard-sphere solvents. The probability distribution of spheroidal cavities in the solvent is shown to be well described by a Gaussian function, and the variations of fit parameters with cavity elongation and solvent properties are analyzed. The excess chemical potentials of...

Comparisons of the Cubed Sphere Gravity Model with the Spherical Harmonics

The cubed sphere gravitational model is a modification of a base model, e.g. the spherical harmonic model, to allow for the fast evaluation of acceleration. The model consists of concentric spheres, each mapped to the surface of a cube, and combined with an appropriate interpolation scheme. The paper presents a brief description of the cubed sphere model, and a comparison of it with the spheric...

Models of tumour spheroid response to radiation: identifiability analysis

Two spatially uniform models of tumour growth after a single instantaneous radiative treatment are presented in this paper. The two ordinary differential equations models presented may be obtained from two equivalent partial derivative equations models, by integration with respect to the radial distance. The main purpose of the paper is to study their identifiability properties. In fact, a prel...

Spheroid and Disk Signatures in Galaxy Bulges

Recent progress on the structure and dynamics of bulges is reviewed. Those aspects that link galaxy bulges either to oblate spheroids akin to elliptical galaxies or to rapidly-rotating, flattened systems more nearly resembling the products of disk internal transformations, are highlighted. The analysis of surface brightness profiles derived from HST data is reviewed to show that unresolved nucl...
