Given the lack of significant conditional effect for the syllable similarity and accuracy scores at 65d (see Results, below), CV scores for individual acoustic features were only conducted on data obtained at 75d.
The lack of a conditional effect in adults is surprising, given the equivalent amount of singing-induced FoxP2 down-regulation in juveniles (Teramitsu et al., companion article) and adults [27], [28].
While studies have examined antisense transcripts of S. cerevisiae for inverse expression in stationary phase and stress conditions, there is a lack of comprehensive analysis of the conditional specific evolutionary characteristics of antisense transcription between yeasts.
However, the lack of a conditional allele of Nanos3 has hampered delineation of each contribution of NANOS2 and NANOS3 to the male germ cell pathway.
The difficulty in studying multifunctional proteins and proteins essential for intraerythrocytic development in Plasmodium is the lack of robust conditional knockout strategies.
To date, however, due to the lack of a CD146 conditional knockout mouse, most studies on the role of CD146 in angiogenesis are in vitro assays on cultured cell lines; in vivo studies are limited to zebrafish (Chan et al., 2005; So et al., 2010) and xenograft tumor models.
However, a significant challenge in using zebrafish is the current lack of target-specific conditional mutagenesis technology, although the new ZFN method has the potential to enable the development of a knock-in approach (Woods and Schier, 2008).
Future studies aimed at addressing this question will necessitate the generation of EBs lacking VE or the conditional ablation of VE from established EBs.
Various methods have been proposed to address the lack of conditional independence in latent class models for record linkage.
In addition, there are youthful marriages; marriages of very short duration; marriages marked by serious emotional, physical, or substance abuse; deviant sexual practices; profound and consistent irresponsibility and lack of commitment; conditional consent to a marriage; fraud or deceit to elicit spousal consent; serious mental illness; or a previous bond of marriage.
We note that lack of robust conditional differences at 65d and in mature song rules out that increased variability at 75d in the UD-UD condition reflects singing fatigue.
