"cross threshold" is a correct and usable phrase in written English.
You can use this phrase to refer to the act of passing a certain limit or point. For example, "Jim crossed the threshold to enter the room."
Relative expression was calculated using the comparative cross threshold (Ct) method.
The delta delta cycle threshold (ΔΔCt) method was used to calculate the real-time PCR results, which measures gene expression between the model and a housekeeping gene (∆ cross threshold), then between the model and control groups (∆∆ cross threshold).
The mRNA expression was quantified using the comparative CT (Cross Threshold, the PCR cycle number that crosses the signal threshold) method [ 27].
Samples were rejected if multiple TBP replicates failed to cross threshold in <36 cycles or if the median absolute deviation of quantified TBP across replicates was greater than 25%% (5 of 275 samples).
Note that the half-wave rectification is included in this particular model simply for analogy with the multi-filter model discussed below; it has no effect on predicting the latency because negative values of y(t) cannot cross threshold.
In other words, sample RNA and cDNA, when used to assess endogenous housekeeping transcripts by qPCR, should be diluted such that the resulting amplifications cross threshold (generate CT values) within the same region that the target amplifications do.
The endpoint is reached when data cross thresholded W-mean-Hotelling value (UCL).
We don't cross thresholds, we don't meet goddesses and we don't return to our villages with elixir.
Targeted loss of hub trees, however, can cross thresholds that destabilize ecosystems.
If v crosses threshold, an event will be generated that will be delivered to target.
Data are presented in terms of crossing threshold (Ct), which was calculated as ΔCt=Ct(Htr2c)–Ct(Cyclophilin).
