The phrase "a slightly more robust" is correct and usable in written English.
It can be used when comparing the strength or durability of something in a subtle way, indicating a small increase in robustness.
Example: "After testing the materials, we decided to use a slightly more robust option for the construction to ensure longevity."
Alternatives: "a somewhat stronger" or "a marginally sturdier".
From the post-it, the next stop is the Concept Poster — a slightly more robust prototype.
A slightly more robust method is to compare the current polling against the long-term trend in each survey.
Alongside Laurent-Perrier's Ultra-Brut, Pol Roger's Pure, made in a slightly more robust, fruitier style, is probably the most widely available.
Then it became a slightly more robust website.
The CBOE's has been a slightly more robust 3,387 daily trades (though adjusted for contract size, they are similar notional dollar amounts).
Oh, and Moga's take even sports a slightly more robust internal battery to go with its identical price tag — on paper it looks like Logitech's already running in second place.
Cheke and Hume have suggested that the French word (bécasse) from Dubois' original description, usually translated to "woodcock", could also mean oystercatcher, another bird with a long, straight, but slightly more robust, bill.
Tree construction with Bayesian estimates of relative hybridization levels for each species was slightly more robust than a simple average or median of ratio values.
It is also interesting that our 4T07 cells with the greatest extent of APC knockdown (APC shRNA1) had a more modest effect on migration but slightly more robust impact on morphology.
Another solution is to use, generalized estimating equations (GEE) [ 31], an alternative method that is (in our experience, slightly) more robust to this assumption failure.
Consistent with constitutively dimeric Lpd having a higher affinity for actin, GFP-LZ-Lpd850-1250aa dislightlyslightly more robust leading edge membrane localization and the intensity of presumptive endocytic particles were brighter compared to those observed in cells expressing GFP-Lpd850-1250aa.
