The remainder of the differentially expressed genes showed a continuum of additive, mid-parental expression pattern among the hybrid-inbred triplets (see Additional file 10).
While Tregs are easily defined in mice by concurrent expression of FOXP3 and high levels of CD25, in humans CD25 cannot be clearly delineated into low and hi expressing subsets due to a continuum of expression.
The tunneling current density J from a deep-level state to a continuum of free states in a conduction band can be expressed as follows [9, 29]: J ∝ P = A E exp − B E (1).
There, emotional expression is inherent in a continuum of movement.
Membership in fuzzy sets is expressed in degrees of truth i.e., as a continuum of values ranging from 0 to 1.
The dichotomy between spike-synchrony and mean firing rate is therefore artificial and should be avoided, as these two represent only extreme cases of a continuum of timescales that are expressed in cortical dynamics.
In DD, Vipr2−/− mice expressed the continuum of behavioral phenotypes common for this genotype, from robustly rhythmic with a single dominant component of locomotor behavior (Fig. 1C 1D), to apparent arrhythmicity, often with multiple, low power periodic components (Fig. 1E 1F).
Rather than a single set of defined behaviors, several authors (17– 20) have proposed that machismo can be expressed differently in different men, with their behavior oscillating within a continuum of positive and negative characteristics.
It has therefore been recommended that it should not be presented as an integral part of a continuum of levels of agreement but, if used at all, be presented separately from categories expressing agreement levels [ 41].
In addition, functional changes are expressed over a continuum, making it difficult to document the damage which often is expressed as more than one lesion and at different intervals or stages of development.
