Anterior corneal profile with variable asphericity [PDF]

, 2009
We present a corneal profile in which the eccentricity, e(Q = -e²), has a nonlinear continuous variation from the center outwards. This nonlinear variation is intended to fit and reproduce our current experimental data in which the anterior corneal ...

On the asphericity of ribbon disc complements

, 1985
The complement of a ribbon n n -disc in the ( n + 2 ) (n + 2) -ball has a 2 2 -dimensional spine which shares some of the combinatorial properties of classical knot ...

Abundance Tomography of Type Ia Supernovae [PDF]

, 2004
Many uncertainties about the physics of Type Ia Supernovae have been revealed in the recent past, and numerous pieces are puzzled together to achieve a complete description of the phenomenon of thermonuclear explosions in the sky. However, very important

Asphericity and clumpiness in the winds of Luminous Blue Variables

, 2005
We present the first systematic spectropolarimetric study of Luminous Blue Variables (LBVs) in the Galaxy and the Magellanic Clouds, in order to investigate the geometries of their winds.

Infinitesimal asphericity changes the universality of the jamming transition

The jamming transition of non-spherical particles is fundamentally different from the spherical case. Non-spherical particles are hypostatic at their jamming points, while isostaticity is ensured in the case of the jamming of spherical particles.
