The phrase "activities upstream" is correct and usable in written English.
It can be used in contexts related to processes, workflows, or supply chains, referring to actions or tasks that occur earlier in a sequence or system.
Example: "To improve efficiency, we need to focus on optimizing our activities upstream in the production process."
Alternatives: "preliminary actions" or "initial tasks".
PC 4 and PC 5 represent industrial activities upstream and agricultural activities.
PC 1 represents the contribution of industrial activities upstream and decomposition of organic materials by microbial organisms.
Human and geological processes and activities upstream of HD were assessed by analyzing and documenting all potential sources of HD salinity.
The current implementation of the SysML tends to be design-centric with minimal support for activities upstream of design such as product line engineering, goal conflict resolution and hazard/threat modeling.
The N-terminal extended sequences of atp6 in Rhazya may have been cleaved by genomic recombination activities upstream of the protein gene, but remnants of these extended sequences were not detected due to high sequence divergence and frequent recombination activities.
We refer to proactive digitization as the act of moving digitization activities upstream in the collecting process to eliminate the creation of new legacy data and to encourage the submission of digitized data concurrent with the deposition of physical specimens (Appendix S14).
While POP1 inhibits IKKα/IKKβ kinase activity upstream of IκBα phosphorylation and cannot inhibit transactivation by the active p65 subunit [ 25], POP2 inhibits transactivation by p65 [ 12].
This allowed us to examine whether these events were also associated with activation of OTc assemblies, which might be expected if assembly activity represents premotor activity upstream of oculomotor outputs.
Furthermore, both railroad and telecom firms depend on economic activity upstream to provide traffic over their networks.
The reason for these different findings is not known but one explanation might be that a c-MYC binding element, a putative E-box sequence located in the PEG10 intron, was included in the promoter-reporter constructs of this previous study, whereas we analysed only the PEG10 promoter activity upstream of the mTSS.
In addition, their reporter contained a putative c-MYC binding element, an E-box consensus sequence located in the PEG10 intron, considered to be responsible for increased PEG10 expression by c-MYC, whereas we analysed the PEG10 promoter activity upstream of the mTSS in HEK293 cells.
