The phrase "at a high initial" is correct and usable in written English.
It can be used when discussing something that starts at a significant or elevated level, often in contexts like pricing, investment, or performance metrics.
Example: "The project requires a commitment at a high initial cost, but the long-term benefits justify the investment."
Alternatives: "at a significant initial" or "at a substantial initial".
But it comes at a high initial cost.
At a high initial temperature of 900 K, the formation of "cold" AI kernels is inhibited with increased turbulence intensity.
The proposed Soft Composite solution is achieved by impregnating a prefabricated polyethylene terephthalate braided sleeve, held at a high initial fibre angle, with a silicone prepolymer.
The effect of an optimized complex slip surface on the hydrodynamic performance is much larger at a low initial critical shear stress than at a high initial critical shear stress.
A synthetic NAPL composed of equal mass fractions of n-C10, n-C12 and n-C16 was mixed with soil at a high initial NAPL concentration equal to 100 g/kg-soil.
In response to a sudden stimulus, PU males and C females showed a higher initial level of locomotion compared to C males, which only gradually declined, while PU females started at a high initial rate, changing rapidly to immobility.
Spurred on by the initial work of Shoemaker et al. [ 11], who showed that high-risk surgical patients could have their mortality decreased by a preemptive resuscitation protocol aimed at achieving a high initial DO2, referred to then as 'survivor levels of Dof'.
Several attempts have been tried so far to render concrete workable at construction site including starting with a high initial slump at the stationary plant, or retempering with water and/or with chemical admixtures at construction site.
The hybrid annealed at 300 °C (MG-300) shows a high initial discharge capacity of 241 mAh g−1 at 0.1 C with a graphene loading rate of 9%.
Biodistribution of 131I-14C5 chAb in αvβ5 − Colo16 tumor-bearing mice revealed a high initial uptake at 24 to 48 h p.i., which decreased significantly at 72 h p.i. (p < 0.05, non-parametric Mann–Whitney U test; Figure 7a).
Once fluorescent values were normalised for the number of cells (using OD580), the expression of mCherry decreased steadily from a high initial level (at Day 3) over the time course, indicating that there was no transient up-regulation, but that it was probably an artefact of our inability to measure LacZ activity at the earliest timepoint.
