Sentence examples for below the sensitivity threshold from inspiring English sources

To determine the class of photopigments which this phototransductive system uses, we exposed a group (n = 7) of human subjects to red light below the sensitivity threshold of a scotopic (i.e. rhodopsin/rod-based) system, yet of sufficient strength to activate a photopic (i.e. cone-based) system.

This sensitivity threshold precedes a sharp increase in false positive rate and therefore excluding sites below the sensitivity threshold ensures that the number of cavities without ligand-binding potential introduced to the dataset is limited.

These factors limit our experimental time frame to 24 Hrs, an interval in which we observe very little normal mHDx-1 clearance, and any decreases in clearance may be below the sensitivity threshold of the assays.

However, the Km estimate is based on the lower portion of the peaks, where the dopamine "signature" of oxidation and reduction currents tends to be lost below the sensitivity threshold for differentiating dopamine from electrical noise [22] and, thus, where the voltammetric signal may no longer reflect dopamine itself.

Thus, the independent effect of a single enhancer or variant may be below the sensitivity threshold of standard assays.

The most established explanation is IgG deposition on RBC below the sensitivity threshold for DAT or, less frequently, occurrence of IgA as the only autoantibody class [ 4, 18].

2: if auxin concentration c in a metamer falls below the auxin sensitivity threshold T, then the metamer becomes a branch and an auxin source (red).

In many conditions, such as the low coverage of primers, the absence of a tested gene rearrangement in the tumor genome, DNA degradation in the sample, and the number of tumor cells below the detection sensitivity threshold, clonal gene rearrangement may not be detected.

However, dilution equal or beyond 3c brought the concentration of detectable compounds below the minimum sensitivity threshold of optical spectroscopy.

0.05% PHMG-P and 0.05% CHX over 3 min also demonstrated insufficient anti-microbial activity (RF 3.55 and 3.73 correspondently), when extended to 5 min treatment, a reduced amount of S. mutans below the methods sensitivity threshold (≤1 × 10 CFU/ml) was obtained.

22 However, genotyping was not performed prospectively and could not be performed retrospectively, so "nonproducers" could not be distinguished from patients who produce CA 19-9 but presented with values below the assay sensitivity threshold (<8 U/ml and <1 U/ml prior to and after October 6, 2004, respectively).
