"Such assertions were not supported by relevant and reliable background material".
This impression is reinforced by an ingrained, racist view of Caribbean identity, which has been a reliable background to corporate salesmanship.
Although many physicists expect that the universe really does shift and shimmer on tiny scales, where quantum effects should bend space-time just as gravity does on large scales, the absence of a reliable "background" means that there is no Swiss watch, even in theory, for the particle physicists.
Chien et al. [14] proposed a background registration technique to estimate a reliable background image.
Zhao et al., "Background subtraction via robust dictionary learning") relies on sparse representation and dictionary learning to address the problem of reliable background model estimation from a cluttered training sequence.
To generate a more reliable background model we modified the method to account for the dimmer-distributions in human genome and also on human promoter (where Pur-Pyr, Pur-Pur and Pyt-Pur are not equally probable).
It is obvious that all these fascinating processes can only be studied on a reliable phylogenetic background [ 9, 25- 28].
The present study is designed to fill the gap between the rapidly increasing knowledge of various aspects shaping African cichlid evolution and the lack of a reliable phylogenetic background and divergence time estimates.
In contrast, the lack of genomic data on Anopheles taxa other than A. gambiae s.s. and the absence of a reliable phylogenetic background do not allow to infer the evolution of characters along well-defined lineages (e.g. in monophyletic sister-groups) [ 21, 41].
However, this method is not reliable when the background brightness is low or the background has the similar chrominance with foreground.
