The antipneumococcal immune responses were measured using a functional opsonophagocytic activity (OPA) assay, and these responses were generally concordant with the immunoglobulin G responses.
To obtain a broader understanding of the effects of dichlorvos on liver metabolism, we performed a genome-wide analysis of gene expression in the liver of zebrafish exposed to DDVP and identified biological responses to DDVP using a functional analysis of differentially expressed genes.
For example, we avoided the need for the kind of 2-stage fitting process that has previously been used to decide whether a functional response should be considered sigmoidal [38], because we represent uncertainty about the form of the functional response explicitly by the posterior distribution of the parameter m.
Second, the model used climatically controlled growth rates as a functional response to climate variability, leading to an increase in generation time for sub-optimal climates.
Such a functional response is called a ratio-dependent functional response.
We used a functional approach to discover and accurately annotate porcine immune response genes.
For each participant, functional MRI responses were modelled using a canonical haemodynamic response function, and the general linear model was used to perform a first level, within-participants analysis on the functional data from each participant individually for the primary contrast (EFT minus control task), with spatial realignment parameters entered as covariates.
We evaluated variation in selection among individual cougars by time of day, home-range location (i.e., rural vs. wilderness cougars), and using functional response curves.
The investigation of multiple bifurcations has also been carried out on the following predator-prey system with 'group defense' using the nonmonotonic functional response g(x) = xe -βx (see [10]) d x ( t ) d t = r x 1 - x ( t ) K - c x ( t ) y ( t ) e - β x ( t ), d y ( t ) d t = y ( t ) [ - d + α x ( t ) e - β x ( t ) ]. (1.2).
Such quantitative descriptions of the trophic links in biological communities are formulated mathematically using functional response models.
