The phrase "at a weaker level" is correct and usable in written English.
It can be used to describe a situation, condition, or performance that is not as strong or effective as another.
Example: "The team's performance was at a weaker level compared to their previous matches."
Alternatives: "at a diminished capacity" or "at a lower intensity".
CD16 was expressed on a DDC subpopulation, but also, at a weaker level, on LC (Figure 4D).
VvSUC11 and VvSUC12 are detected in all organs but at a weaker level and VvSUT2 is the less expressed sucrose transporter being only weakly detected in young leaves and roots.
In ap-Gal4, UAS-RFP, UAS-hh-N discs, ectopic En is detected throughout the anteroventral quadrant of the wing pouch (Fig. 6C C″), albeit at a weaker level compared to Hh-WT discs.
Furthermore, we show that the ectopic co-expression of dpn with E spl m3 or E spl mγ could reproduce, although at a weaker level, many of the Notch over-expression effects, whereas the simultaneous loss of function of dpn and E spl)C mimics most of the effects produced by the Notch signalling insufficiency.
β-tubulin III was present throughout the cytoplasm and along neurite branches/extensions of both proliferating and differentiated N-type cells; expression did not appear to change after 9 cRA-induced differentiation (Fig. 2B, E). β-tubulin III was also present throughout the cytoplasm of S-type cells, albeit at a weaker level compared to N-type cells (Fig. 2C, F).
Fresh CD4+CD25+ T cells also expressed surface LAP at a weak level (Figure 2A).
Therefore, we conclude that some cohesive ties were maintained, albeit at a weak level.
Under the assumption that candidate genes for Pl ARG are constitutively expressed at a weak level in non-inoculated plants [ 14, 15], seedlings were grown in the greenhouse at a 14 h light (18°C /10 h dark (16°C) cycle for eight days.
"Housing market activity remains at a very weak level that historically has been associated with falling house prices, despite rising modestly from their lows earlier this year".
Overall, the jobs market is flat, operating at much weaker level of demand than before the recession, and still at risk of a serious relapse.
For example, monomethylation and dimethylation of histone H3 on lysine 4 (H3K4me1/2) typify enhancers within a given cell type, although the H3K4me2 mark is also present at proximal promoter regions, albeit at weaker levels [ 1, 15, 16].
