Age-related Changes in the Foveal Bulge in Healthy Eyes
BACKGROUND Intact foveal bulge has been associated with good visual outcome in retinal diseases. The aim of this study was to study the variation in foveal bulge with age. METHODS It was an observational cross-sectional study conducted between October 2014 and December 2015. Totally, 101 eyes of 101 healthy volunteers were studied in a tertiary care center. All individuals had best corrected ...
متن کاملBulge Formation
The currently discussed theories of bulge formation are reviewed, including the pri-mordial scenario, where bulges form rapidly and then accrete disks, the secular scenario, where bulges are formed by dynamical evolution of disks through bars and galaxy interactions , and some combinations of both, where formation of bulges and disks are more continuous and interleaved. The various scenarios ma...
متن کاملSpiral arms, bar shape and bulge microlensing in the Milky Way
A new model for the luminosity distribution in the inner Milky Way is found, using a non-parametric penalized maximum-likelihood algorithm to deproject a dereddened COBE/DIRBE L-band map of the inner Galaxy. The model is also constrained by the apparent magnitude (line-of-sight) distributions of clump giant stars in certain bulge fields. An important new feature is the inclusion of a spiral arm...

متن کاملWormholes in Shape Space: Tracking Through Discontinuous Changes in Shape
Existing object tracking algorithms generally use some form of local optimisation assuming that an ob ject s position and shape change smoothly over time In some situations this assumption is not valid the track able shape of an object may change discontinuously for example if it is the D silhouette of a D object In this paper we propose a novel method for mod elling temporal shape discontinuit...
