The phrase "a strict reference" is correct and usable in written English.
It can be used when discussing a specific and precise citation or source of information that must be adhered to.
Example: "In academic writing, it is essential to provide a strict reference for all sources to maintain credibility."
Alternatives: "a precise citation" or "a specific source".
A total of 11,301 genes were found with RNA-seq read coverage ≥ 90% of their transcript length in all three strains using Cufflinks and the Ae. aegypti genome annotation (AaegL1.2) as a strict reference.
Tree views were produced using Interactive Tree Of Life [ 49] To compare each of the 5282 protein trees with the reference topology we used the EEEP program [ 6, 34] with a bootstrap collapse threshold of 95% (i.e. considering only nodes with PP ≥ 95%) and a strict reference tree ratchet (-rR).
The 19 672 trees with at least one bipartition supported at PP = 0.95 were submitted individually to EEEP, with five different types of ratchet constraints applied in separate runs: a) no constraint; b) a permissive test tree distance ratchet; c) a strict test tree distance ratchet; d) a permissive reference tree distance ratchet; and e) a strict reference tree distance ratchet.
For evolutionary analysis of the targets of Hfq-associated core sRNAs, each of the corresponding Bayesian nucleotide trees was compared to the E. coli– Shigella reference topology using the EEEP program (Beiko and Hamilton 2006) with a bootstrap collapse threshold of 95% and strict reference tree ratchet (-rR).
Affective responses were assessed with strict reference to the DSM IV (APA, 2000 [7]), which refers to a PA as "a discrete period of intense fear or discomfort", in which four (or more) out of a list of thirteen predefined symptoms develop abruptly and reach a peak within 10 minutes.
This is not a strict mathematical reference but mathematicians like Blaise Pascal have thought about vacuum.
Early morning cortisol levels seems to be a biological marker for the individual's adrenocortical activity when measured with strict reference to the time of awakening [ 46].
We must study these strata in strict reference to their chronological order as deduced from their superposition, and other relations.
We did not apply any specific quality criteria to the assessment beyond the strict reference selection criteria.
For tree comparisons in which the unratcheted run returned a solution, each type of ratchet was able to recover the correct edit distance from >90% of all data sets, with both permissive ratchets yielding better accuracy (97.1% for both reference and test tree distances) than the strict reference tree (93.8%) and test tree (94.1%) ratchets.
Moreover, since reference gene combinations have been recommended (Vandesompele et al. 2002), our effort was to come up with a combination of genes expressed stably under different variables to provide a strict and dependable reference parameter.
