The phrase "activity implies" is correct and usable in written English.
You can use it when discussing the relationship between a specific activity and the conclusions or assumptions that can be drawn from it.
Example: "In this context, the activity implies a level of commitment that is essential for success."
Alternatives: "activity suggests" or "activity indicates".
The question is whether all goal-directed activity implies that the goal must be understood as a "good".
Correlation between cytotoxicity and topoisomerase II inhibitory activity implies that compound 25 can be a possible lead compound for anticancer drug impeding the topoisomerase II function.
For many ecosystem types, those prerequisites will be rarely met in practice: sufficient market activity implies sufficient habitat turnover, but most ecological networks are not robust enough to buffer frequent habitat turnover.
In addition, epileptiform activity implies synchronization of oscillators.
Stronger solar magnetic activity implies stronger magnetic fields, weakening the transport of GCRs.
Such heterogeneity can be likely, as the existence of foreshock activity implies ease of initiating rupture around the hypocenter area.
In our study we observed a significant relation between active TGF- β1 levels and urokinase activity, implying plasmin, via urokinase-mediated plasminogen activation, as a principal candidate of latent TGF- β1 activation.
Hawinkels et al (2007) also observed a significant relation between active TGF- β levels and urokinase activity, implying plasmin, via urokinase-mediated plasminogen activation, as a principal candidate of latent TGF- β activation.
In this study, DHT does not markedly affect the activation of CEBPD reporter activity, implying that a compromised molecule or signaling is established to support CEBPD existence in the AR-positive or androgen-insensitive environments.
We demonstrate that axis protein accumulation peaks ∼150 bp downstream of transcript ends and is actively driven by differential promoter activity, implying that axis proteins are not stably bound to DNA.
The presence of glucose-1,6-bisphosphate, an activator normally needed for this superfamily, did not enhance the activity implying that the enzyme may have been purified as the active, phosphorylated form [ 23].
