It can be used to describe the involvement or performance of individuals or entities at various points in a process or timeline.
Example: "The project requires team members to be acting at different stages to ensure its success."
Alternatives: "operating at various phases" or "functioning at different points".
The results from the longitudinal-QTL approach will help to understand the genetic factors acting at different stages of lactation and will assist in positional candidate gene research.
These results have also revealed new insights regarding the relative and simultaneous effects of multiple positive density dependent processes acting at different stages of the life cycle on parasite transmission thresholds.
The host specificity of S. enterica serovars appears to be a complex phenomenon governed by multiple factors acting at different stages of the infection process, which makes identification of the cause/s of host specificity solely by experimental methods difficult.
Adipogenesis is tightly controlled by a complex network of transcription factors acting at different stages of differentiation.
The DNMTs thus represent the writers of the 5mC state, with different members of this protein family acting at different stages of the cell cycle.
It uses the Model of Pathway to Treatment as a framework to allow analysis of the factors acting at different stages in the pathway.
16 Here, we use a mathematical model to investigate the effects of combining antimalarial vaccines acting at different PE stages of the life cycle.
The differences in risk trends in previous studies, mentioned above, are possibly because of different methods used for assessing obesity, and to different disease mechanisms acting at different prostate cancer stages and grades (Gong et al, 2006; MacInnis and English, 2006; Littman et al, 2007; Rodriguez et al, 2007).
These findings highlight the important role that the existence of multiple Allee or positive density dependent effects acting at different population life history stages, and importantly their interactions, can play in the population dynamics and management of populations [23].
The action of miRNAs in translation repression appears to involve various molecular mechanisms acting at different steps of the initiation stage or at the elongation stage (reviewed in Filipowicz et al, 2008; Wu and Belasco, 2008).
The model contains two subsystems acting at different time scales.
