In many studies, the different cellular components of the TME are treated as relatively invariable factors that are assumed to play a similar role in tumor samples from different patients.
For emitters at a finite distance we are forced to use a different mapping since the origin of each photon path is likely to be relatively invariable.
The other factors involved in soil formation are considered to be relatively invariable.
In typical wired networks where the route for the connection is relatively invariable, TCP performs well and network congestion is the key factor affecting its performance.
While the absorption wavelength peak for metal NPs would change with the change of shape, the responsible condition(s) for optimizing the efficacy remains relatively invariable.
These variations were found within relatively invariable parts of each locus, including the signal peptide, trans-membrane and cytoplasmic regions (Figure 2), giving these sequences the genetic basis for becoming separate genes.
This evolutionary history suggests that the bacterial population of the esophagus should remain relatively invariable.
Holins target the relatively invariable cytoplasmic membrane, while phage endolysins recognize and degrade the cell wall, which is highly variable.
Intuitively, phase determination for highly variable nuclear sequence loci should be more challenging than for relatively invariable markers.
Of particular interest is the paaABCDE operon which is relatively invariable (see previous results), but from this analysis it is still subject to gene turnover and replacement.
