The phrase "focal factor" is grammatically correct and can be used in written English.
It refers to the most important or central aspect of a situation or topic. Example: The focal factor in the success of our business was our strong customer service.
As shown in Table 1, all CR /AVE values exceed the recommended threshold values of 0.7 / 0.5 (Fornell and Larcker 1981), and all AVE values exceed the squared correlation between the focal factor and any other factor.
A possible solution is to use multiple environmental contrasts with respect to the focal factor, say temperature, to remove idiosyncratic effects of specific localities (Kawecki and Ebert 2004).
Senescence of the neurons is believed to be a focal factor in the development of age-related neurodegenerative diseases such as Alzheimer's disease.
Alternatively, if the same factor is suggested to play a major role in shaping the geographic mosaic of coevolution at multiple spatial scales of a system, the importance of that focal factor will be further emphasized.
Notable examples are studies that combine a breeding design along with exposure to the focal factor in either common garden experiments or via outplanting (Parsons 1997) or that combine assessments of narrow-sense heritabilities with selection experiments (Kelly et al. 2012).
Hence, we need to properly understand the spatial scales at which focal factors drive the geographic differentiation of coevolutionary interactions, thereby elucidating the relative contribution of such factors to the ecological and evolutionary dynamics of interspecific interactions.
Contrary to this supposition, the factors mapped typically accounted for an appreciable portion of the focal gene's transcript variation.
First, researchers mapped factors affecting transcription of focal genes to cis (position of the focal gene) and other regions of the genome (trans).
Various factors might influence the formation or influence the course or severity of VMA; these might include vitreous liquefaction, focal anatomic factors that might potentiate foveal adhesion (for example inflammation or constitutional factors as yet undefined), or internal limiting membrane (ILM) integrity.
Ten years later, simple tachycardias caused by focal arrhytmogenic factors were being cured successfully in many centres worldwide.
Thus, we were not able to adjust the effects of the focal risk factors for objective measures of physical capabilities like gait speed, grip strength, or balance.
