Performance improvement of Bayesian phylogenetic inference for multicore computers.

A mirror assembly in which the mirror housing and multi-function backing plate provide various useful functions. The multi-function backing plate supports not only a conventional reflective element but also supports a wide angle reflective element. The wide angle reflective element may be adjustable. The multi-function backing plate supports an indicator light assembly so that the mirror assembly can provide an indicator light function. The multi-function backing plate also supports a recessible spot or approach lamp which, when the mirror is in an operative position, is recessed within the housing. When the mirror is in an inoperative state, the multi-function backing plate can be rotated so as to expose the spot or approach light. Various light pipe configurations enable transmission of light projected from a light source mounted to and behind the multi-function backing plate to project light through the light pipe externally to the mirror housing to provide an indicator light function.
