"It was man-made, capable of infinite variation... capable of being stopped before ultimate self-destruction".
Each oscillator is capable of frequency variation for different pitches and is capable of reproducing a single melodic line.
Of the processes capable of maintaining variation, negative frequency-dependent selection (where rare types are favoured by selection) is the most powerful, at least in theory1; however, few experimental studies have confirmed that this process operates in nature.
Normal kinematic joint can be transformed to variable kinematic joint VKJ), which refers to a kinematic joint that is capable of topological variation in a mechanism, by utilizing effect of friction and self-locking.
Finally, crucially, it is also capable of modeling variation in production.
Models of the theoretical perception of the average colour pattern suggest that the crabs are physiologically capable of discriminating variation in spot size and distribution.
Therefore, in this study, we declined the globin elimination process because our intention is to develop a simplified mRNA analysis method capable of detecting variation of gene expression with moderate sensitivity.
Recently, recombinant antigens of P. jirovecii have been developed that show promise as reagents for serologic studies: Kexin 1, which is encoded by a single gene; the major surface glycoprotein (Msg), which is encoded by multiple genes and is capable of antigenic variation [20] [21].
To meet this challenge, hybridization-based microarray assays have been developed that are capable of measuring variation in the expression of hundreds-to-thousands of genes in multiple samples in a single experiment [ 12, 13].
