In the multiuser scenarios upon a multicarrier system, a subcarrier in deep fading to one user may be of good quality to another user, which lends support to dynamic subcarrier allocation on improving system throughput [2 5].

Surveys of practice among hand surgeons [ 5] have highlighted wide variation in the use of post-operative splints [ 6, 7], largely due to a lack of good quality evidence to support their use.
However, the fact that half of all obstetricians now claim to be using the 'overlapping' method suggests that there is a change in practice taking place, despite the absence of good quality evidence to support this.
However, at present, there is limited good-quality evidence to support the use of these individualized approaches.

Unfortunately, there is currently little good-quality evidence to support the use of specific ART-related laboratory processes, including culture strategy and selection of blastocysts for transfer.
In short, although evidence is conflicting (Goossens et al., 2008), there is no good-quality evidence to support a benefit of routine PGS in the prediction of pregnancy outcomes (Staessen et al., 2004; Baart et al., 2006; Twisk et al., 2006; Coulam et al., 2007).
