Sentence examples for secondary shift from inspiring English sources

If a secondary shift in lifestyle resulted in X. peckii's ancestors becoming diurnal again (which indeed they are), then the abundance of receptor cells within each unit could have led to a secondary increase of visual resolution within each eyelet.

Our reconstruction supports colony fission as a secondary shift among ants (Cronin et al., 2013).

Local deviation of Cα chemical shifts from random coil values (termed secondary shift) gives information about the secondary structure propensity of the backbone.

Under this hypothesis, the genetic similarity between eastern and central-western African populations from the Sahel would then be explained by two non-mutually exclusive processes, namely significant gene flow across the Sahel, or secondary shift from pastoralism to agriculturalism in those Sahelian and East African populations that practice agriculture nowadays.

The correlation of 13Cα secondary shifts with both 3D structure and heteronuclear 15N NOE values indicates that natural abundance carbon chemical shifts are useful probes for backbone structure and dynamics of membrane peptides.

The secondary structure of TGF-β313 was assessed by analyzing the secondary shifts using the program PECAN, which provide a sensitive and accurate indicator of secondary structure propensities.

The NMR data were consistent with this interpretation and analysis of the secondary shifts, shown in Figure  7B, indicated that residues 10 29 form a helix in solution.

The secondary shifts for these residues became more negative on addition of TFE, again indicating that the helical structure was stabilised in the presence of TFE.

If these ΔδCα secondary shifts are entirely attributed to the 2% bound state, secondary shifts in the CR-bound state are ∼50-fold larger and therefore indicative of a high population of α-helical backbone ϕ and ψ angles, even while not rigidly anchored to the CR micelle.

Indeed, decreased NMR carbon secondary shifts were observed throughout the AH and extending well into the CH domain, confirming decreases in both nucleation and propagation of the helical conformation.

Secondary, shifted siRNAs (21% of the total siRNAs from TAS3c) were also observed (Additional file 1: Figure S6C), similar to that in Cassava TAS3c, exemplified by the peaks in the middle of D6+, D6- and D5-.
