an upstream position

Grammar usage guide and real-world examples

USAGE SUMMARY

The phrase "an upstream position" is correct and usable in written English.
It can be used in contexts related to processes, workflows, or hierarchies where something is situated earlier in a sequence or closer to the source. Example: "In the supply chain, having an upstream position allows us to influence the quality of raw materials before they reach production."

Here, in the experiment, the In particle is placed in the center of the furnace and the Sb particle is placed in an upstream position.

Fig. 3 a SEM image (80° tilted angle view) of InSb nanowires grown with an individual In particle source placed at the center of the furnace and an Sb particle source at an upstream position.

Saba Bank may be an important Caribbean reef habitat because it has a large extent, and it is positioned in an upstream position relative to neighboring Puerto Rico (to the northwest) and the Meso-American Barrier Reef (to the far west), in relation to the direction of flow for the Caribbean current.

From an upstream position it is impossible to assign more or less plausibility to any of the comparators – they all have certain persuasiveness.

These functional findings are consistent with our previous results showing an unexpected activation of AKT and ERK, and indicate that the origin of the antagonistic effect is located in an upstream position before the switch that activates RAS from its inactive GDP form to the GTP activated state.

However, the behaviour of the drag is found to be significantly dependent on Reynolds number, while the forcing of the boundary-layer transition at a fixed upstream position produces a substantial decrease of the drag only for the lower test velocity.

An interesting feature observed in some of the feature maps was that, in subsets of gene upstream regions, there was a preferential positioning of motifs relative to the TLS (examples discussed below); i.e., motifs show a preference to occur at a particular upstream position relative to the start of translation.

Finally, we identified CAAT-box/NF-Y motifs in a more upstream position (maximum peak at -76 with V$NFY_C).

Interestingly, in the latter the maximum peak position is displaced towards a more upstream position (-59 in RT, versus -42 in HK, for E4F, Figure 3), pointing to possible mechanistic differences in the way these factors interact with the initiation complex in the two classes of genes.

ii) TRGV1 shows in its upstream position a short similarity region shared with TRGV8-1, but absent in TRGV2-1 and TRGV9-1 (blue circle in Fig. 2); the same upstream region is present, though less expanded, in TRGV8-1 and TRGV1 vs. TRGV5-2, but is lost in TRGV8-1 and TRGV1 vs. TRGV5-1 (blue circle in Fig. 5).

Although the correlation was not absolute and most likely depended on each specific mRNA sequence (e.g. internal polyA-stretches), there was a clear correlation between the upstream position of the probe and the length-distribution of the cDNA.

Expert writing Tips

Best practice

When describing the relative placement of components in a system, clarify what "downstream" refers to, providing context for "an upstream position".

Common error

Avoid using "an upstream position" without clearly defining the direction of flow or the sequence of operations. Always establish a clear reference point for what is considered "downstream."

Ludwig's WRAP-UP

In summary, the phrase "an upstream position" is a grammatically correct term primarily used in scientific and technical contexts to denote a location or element that precedes another in a sequence or process. As confirmed by Ludwig AI, it is most frequently found in science-related articles. When using the phrase, it's crucial to define the "downstream" reference point for clarity. While technically correct, simpler alternatives may be preferred in general writing for broader audiences.

FAQs

How is "an upstream position" used in scientific contexts?

In scientific literature, "an upstream position" typically refers to a location before a specific point in a process, such as gene transcription or fluid flow. It helps establish the relative positioning of elements within a system.

What is an alternative to "an upstream position" in a manufacturing context?

In manufacturing or supply chain contexts, you might use "a preceding location" or "an earlier point" to describe a stage or resource that comes before another in the production process.

How does "an upstream position" relate to signal transduction?

In signal transduction, "an upstream position" refers to a component that acts earlier in the signaling pathway. For instance, a kinase that activates another protein is considered upstream of that protein.

Is it appropriate to use "an upstream position" in non-technical writing?

While "an upstream position" is technically correct, it's more common in technical or scientific contexts. In general writing, consider using simpler alternatives like "a preceding location" or "an earlier point" for broader clarity.
