Thus any genome-wide acceleration of deceleration of evolution (global deviation of molecular clock) in either of the clades would affect the perceived asymmetry of orthologous evolution.
As far as the possible functional and/or evolutionary causes of the less extreme, yet genome-wide acceleration is concerned, the situation is not as clear and the evidence is conflicting.
Whether reduced negative selection or elevated mutation rates are the factors behind the genome-wide acceleration can be tested using DNA sequence data since these two forces make different predictions.
As for other eukaryotic organisms, genome-wide acceleration of protein evolution, which might be caused by physiological and ecological factors that affect the mutation rate, was observed in the diptera lineages when compared with the beetle lineages [ 9].
Sections Causes of the Increment in Evolutionary Rates and Patterns of Amino Acid Evolution, Genome-Wide Acceleration, and Relaxation of Functional/Structural Constraints are devoted to discussing the possible biological/evolutionary factors that underlie this increment in evolutionary rate.
Finally, section Patterns of Amino Acid Evolution, Genome-Wide Acceleration, and Relaxation of Functional/Structural Constraints presents an evolutionary phenomenon that appears to be unique of Oikopleura, the lack of conservation of cysteine, an amino acid which is regarded as the most conservative.
Across genes, R S values vary by 9 to 41-fold (depending on whether the six species with apparent genome-wide accelerations are included), while R N values vary by only 2 to 3-fold (Table 2).
VIA hopes to change all that with the VX855, a media system processor (MSP) that "offers full hardware acceleration of the widest variety of leading video standards including H.264, MPEG-2/4, DivX and WMV9, allowing smooth playback of high bit-rate 1080p HD video".
Set to be Microsoft® Windows® 7-ready, the VIA VX855 MSP solves the problem by offering support for full hardware acceleration of the widest variety of leading video standards including H.264, MPEG-2/4, VC-1 and WMV9, greatly reducing the workload and thus the power consumption of the processor.
The tail pipe noise from a commercial automotive muffler was studied experimentally and numerically under the condition of wide open throttle acceleration in the present research.
