Variability in both biological and technical procedures can have a great impact on both microarray and qPCR results (2, 4) and, as biological variability cannot be controlled, care must therefore be taken in the experimental design to minimize irregularities and ensure adequate replication to eliminate "noise" in the experiment.
Among them, 209 are detected under both normal and heat shock conditions, and thus are unlikely to result from data irregularity and/or experimental noises.
Six participants were excluded from the analyses for different reasons: three because of irregularities in the experimental procedure; two because many of their gestures were occluded; and one for guessing our interest in gesture during the debriefing.
While theoretical studies have contributed significantly to our understanding of how the brain learns to see, recent experimental discoveries of the spatial irregularity of visual response properties in the rodent visual cortex have prompted new questions about the origin and functional significance of cortical maps.
Experimental measurements showed that, soft tissue irregularities can result in a maximum inclination angle of 3°, between a two-tip sensor and the tissue surface.
New experimental data on the electron density irregularities have been obtained from simultaneous recordings of spacecraft signals at several widely-spaced ground stations.
Experimental investigations of the equatorial plasma irregularities using VHF coherent and incoherent scatter radars were also carried out over Jicamarca by Cohen (1967), Fejer et al. (1975), Farley and Fejer (1975), and many others.
This growth pattern contributes sampling irregularities and certain variance in experimental measurements that prohibit absolute delineation of cellular responses to defined experimental conditions [43]; however, in this study we devised a number of measures into our experimental design for the consistent collection of reliable data.
Early on, Dr. Fano proposed the barest outlines of a theory to explain new experimental data showing an asymmetry, or irregularity, in the way certain atoms absorb radiation.
Research design is quasi-experimental, field, with four longitudinal assessments for two groups (one experimental and one control) of students with irregularity student.
