The phrase "a reference threshold of" is correct and usable in written English.
It can be used in contexts where you are discussing a specific point of comparison or limit in data analysis, research, or technical specifications.
Example: "The study established a reference threshold of 50 decibels to determine acceptable noise levels in residential areas."
Alternatives: "a benchmark level of" or "a standard threshold of".
To design a reference threshold of protein-ligand interaction, a verifying dataset was used in establishing a reference threshold of distance by determining a maximum discrimination between similar and non-similar binding modes.
Using conventional statistics for sample size estimates, 12 participants in each group (n=24 in total) would be required to make clinically decisive inferences on differences in total haemoglobin mass assuming a typical error of 2%, a reference threshold of 3% and types I and II errors of 5%and20%0%, respectively.
The methodology is based on the computation of a reference threshold from the residue generated between the states of the system and the filter estimates such that when the residue takes values higher than this reference threshold the uncertain system is considered in fault.
We have defined observed apnea by a positive response to the question, "Has someone said to you that you stop breathing during your sleep?" The sleep questionnaire (11), as shown in the online appendix, included the Epworth Sleepiness Scale, which provides a measure of daytime sleepiness, that we study with the reference threshold of 10 or higher, which was derived in a general population (12).
In particular, LD in the elite Mediterranean panel decays below the r reference threshold of 0.3 within 2.20 cM.
Using the reference threshold of protein-ligand interaction (correlation coefficient: 0.39), three major clusters can be identified in Figure 3b, clusters c, d and e.
The reference threshold of atom-pair (Tanimoto coefficient: 0.55 in Fig. 2) was calculated via 7 classes of structures showing the complement between atom-pair descriptor and protein-ligand interaction descriptor.
Interestingly, the inferred average LD r value is 0.6 at 0 cM inter-marker distance, i.e. at the maximum resolution provided by the linkage studies, is far below the reference threshold of r = 0.8 currently accepted as the r value to select representative SNPs for GWAS (tagSNPs, [ 54]) in those species where this resource is available.
Furthermore, the summary estimates of positive and negative likelihood ratio's for individual symptoms and signs at each of the three threshold levels are presented in Table 5. Six symptoms are identified as having useful diagnostic value at a reference standard threshold of ≥ 102 CFU/ml, as their 95% confidence interval values do not cross the line of no effect.
It is fair to mention that we used reference threshold values of the conventional biomarkers, while the threshold value for TNC was generated by a ROC curve analysis for this very purpose using our SLE cohort.
In this case, the values of the two first thresholds of the common new set can be those of the reference threshold set τ 1 a, τ 2 a, τ 3 a, but the third is given by τ 3 a * = σ τ 3 b - τ 1 b - τ 1 a with σ = τ 2 a - τ 1 a / τ 2 b - τ 1 b.
