The phrase "a gradient that is" is correct and usable in written English.
It can be used when describing a specific characteristic or property of a gradient in various contexts, such as mathematics, physics, or design.
Example: "The study focused on a gradient that is steep, indicating a rapid change in elevation."
Alternatives: "a gradient which is" or "a gradient characterized by".
The barrier islands are formed by the waves, which build up their equilibrium profile by deposition on a gradient that is too flat.
The dependent variables (ammonia-oxidizing gene abundance and community data) ordinate along a gradient that is driven by vectors related to the independent variables (environmental factors).
As a result, the water phase pressure can be higher than that of oil phase at the deeper zone (middle zone), producing a gradient that is steeper than the capillary pressure curves at the less deep zone (upper zone).
Dpp phosphorylates Mad, which forms a gradient that is highest near the source of Dpp, and low at the lateral areas of the wing disc.
Then the fruit flies loose a directional cue, although the infochemical concentration may have a gradient that is quite useful at lower concentration levels.
We used checkerboard analysis to determine whether vitronectin acts by chemotaxis (migration to a gradient) or chemokinesis (nondirectional migration in the absence of a gradient, that is, when concentrations are the same in the upper and lower chambers).
Running down the Siyarko Tangk Danda ridge that afternoon, the route was perfect underfoot – a soft, dusty yak track, descending on a gradient that was doing most of the work, allowing my legs to spin along below me.
Thus, the WcBiM chip had a gradient that was two times steeper in the SPR reflectance curve than the Au chip.
Linear regression analysis between initial velocity with 20 Hz stimulation and initial velocity without stimulation confirmed this key interaction, demonstrated by a gradient that was less than unity (r = 0.980, F[1,12] = 601.6, p < 0.001; mean gradient 0.897 with 95% CL 0.817 to 0.977, t = 24.5, p < 0.001; Figure 4A).
The abnormal vascular pattern induced by VEGF-A has been attributed to its inability to bind to matrix and, therefore, to form the steep VEGF-A gradients that are thought to be necessary for generating normal blood vessels.
The cell polarity protein kinase Pom1 is a cell polarity protein kinase, which can form a spatial gradient that is greatest at the ends of the cylindrical cell and least in the middle of the cell.
