They are propositions whose only invariable parts are logical ideas.
The only exception is the two invariable amino acids G and L in the PBC (Supplementary Fig. S1).
The pattern of the sclerites is not only rather invariable between individuals of a species and within the series of pleopods of a species, but also conservative within members of putatively monophyletic groups.
This invariable current from RDCM, charging or discharging the only capacitor in circuit is controlled by pulse width modulated signal to realize switch capacitor DAC.
This is most likely caused by the extreme variability in the protein structure of these genes, and the fact that the only common region –the EGF motif– is also very variable, beyond the few conserved amino acids that are invariable among all species (e.g. the six conserved cysteines17).
In our analysis, we chose probabilities above 50% to consider only the almost invariable anatomical core of each single tract and not its periphery (Thiebaut de Schotten, ffytche et al. 2011).
Because the thickness of the finger is a nonlinear variable, it is hard to only use invariable light intensity to vein imaging at infrared 850 nm.
This analysis compares the number of S and NS substitutions by creating a neighbor-joining tree based on dN values (NS substitutions per NS site) and then determining whether mutations are variable (occur more than once in the tree) or invariable (occur in only one branch of the tree).
We used the default options of PhyML_aLRT with the JTT matrix for amino acid substitutions, the proportion of invariable sites set to zero, and with only one category of substitution rate [ 28].
The gamma distribution parameter and the proportion of invariable sites were estimated from the datasets.
The speed and the routes are invariable and if there were exceptions; there were minimal.
