The phrase "a characteristic level" is correct and usable in written English.
It can be used when describing a specific standard or degree of a particular quality or feature that is typical or representative of something.
Example: "The study aimed to identify a characteristic level of performance among the top athletes in the competition."
Alternatives: "a typical level" or "a standard level".
As PEG content in blends exceeds a characteristic level, PEG cold crystallization occurs upon heating of the cool-quenched samples through their glass transition temperatures (Tg).
Although all periodate is consumed during limited oxidation, not all of the resulting dialdehydes are equally degradable, leading to a characteristic level off in molecular weight upon prolonged degradation.
Since higher τ int values exceed a characteristic level of o-p-Ps self-annihilation in a vacuum (0.5 ns) [1, 2], the hypothetical medium formed in the DRC under photopolymerization can be imagined as rather loose substance possessing a wide range of o-Ps trapping sites.
Indeed, while most strains showed a characteristic level of GFP expression that was constant over the temperature range, both adr rde-1 adr rde-1de-4 strands showed adr rde-4e in GFP expression adr rde-4mperature decreastrainsg. 6A, Table 1).
Each choice of a characteristic level should be specific to the system being studied, and hence in the analysis above we assume that such a choice has already been made and the variables are fittingly normalized.
Cortisol is accepted as a robust marker of activation of adrenocortical activity (HPA activity) and follows a 24 hour rhythm with low levels in the evening and a characteristic peak level, usually found the first hour after awakening [ 42, 43].
All HSCs and common lymphoid progenitors express high levels of PU.1, with expression being reduced to a characteristic low level in early B-cell development.
At the same time, assuming ñ = 10, we find from (6) that n ∼ 10 is a characteristic quantum level of the oscillator excited by magnetic field, i.e., there are transitions from the ground level to upper energy levels of the oscillation spectrum of vertical BL.
Further, the nucleated phase grows into separate grains reaching greater sizes, but, in general, they do not exceed a characteristic nanosized level (a controllable crystal growth).
The genomes of the 21 completely sequenced Thermococcales display a characteristic high level of rearrangements.
Consequently many researchers have posited that each individual has a characteristic "set point" level of happiness, toward which he tends to gravitate over time.
