The phrase "at a certain value" is correct and usable in written English.
It can be used when discussing a specific point or level in a numerical or qualitative context.
Example: "The experiment showed that the reaction rate increased significantly at a certain value of temperature."
Alternatives: "at a specific value" or "at a defined value".
With the sand ratio at a certain value, the floating phenomenon is well-controlled.
At a certain value of the potential, pits are nucleated, which propagate in the quasistationary conditions of the galvanostatic curve.
I mean, lack of propagation of uncertainty could be that you're just fixing things at a certain value explicitly by turning genotype probabilities into called genotypes.
The adaptive PMS is designed for charge sustaining such that the state of charge (SOC) can be maintained at a certain value.
In this paper, control strategy that sets Kd at a certain value, and adjusts Kp and Ki in real time is proposed.
Dominant factors are the pulse duration and the pulse time to rest time ratio, the polarisation exhibiting a minimum at a certain value of these parameters.
It was found that dependence of gas induction on geometric parameters like distance between nozzle mixing tube, suction chamber geometry, diffuser angle was either weak or had a clear maxima at or beyond a certain value of the geometric parameter.
In 1911, three years after helium was first liquefied, Onnes working at University of Leiden discovered superconductivity in mercury, when he observed the electrical resistivity of mercury to vanish at temperatures below a certain value.
Beyond this critical point, mitochondria might degenerate as the availability of oxygen decreased, leading to a complete disintegration at pO2 below a certain value corresponding to an approximate distance of 181 μm from a perfused vessel, according to our results.
Consider a point ((x_{1},x_{2})) at which A takes a certain value a. Set (b=Phi(a)).
By increasing inhibitory connectivity strength, the synchrony of resonators first increased and then decreased (Fig. 9 C) showing that, at least up to a certain value, stronger reciprocal IPSCs synchronize the interneuronal population better, as shown in Figure 7.
