This understorey may be used as a resource and refuge by animal species and also function as stepping stones or corridors linking natural areas that would not be connected otherwise (Machado and Lamas [1996]; Lyra-Jorge et al. [2008]).
Furthermore, it identifies market niches in which fuel cells are already close to market readiness and supports their commercialization with the intention that these niches shall function as stepping stones for the breakthrough into mass markets [22].
This raises interesting questions related to reproductive and developpmental strategies, endemism, and faunistic relationships between the Brazilian continental margin and other parts of the Atlantic: Would Brazilian seamounts function as stepping stones in the Atlantic Ocean?
The package vignette (available at http://www.bioconductor.org/packages/release/bioc/vignettes/QuasR/inst/doc/QuasR.pdf) contains more details on QuasR functions, as well as step-by-step examples for typical analysis tasks.
It is commonly known as workflow management and requires the identification of system functions as steps in a workflow process.
In this paper, a meshless model, based on the local Petrov Galerkin approach with Heaviside step function as well as radial basis functions, is developed and implemented for the numerical solution of plane strain poroelastic problems.
Thus, the current vs time is expected to be a step function, as is observed in our experiments.
The Nearctic has been connected to the Western Palearctic through islands that could have easily functioned as stepping-stones facilitating dispersal over the North Atlantic [ 49- 51].
Microbiota features emerging from the stage 1 analyses will also be included and analyzed as mediators in stage 2 using marginal structural models to evaluate shifts in microbiota composition and function as intermediate steps in the nutrition and EED causal pathways to infant growth (mediation analysis) [ 79].
However, when the boundary conditions are time-varying, such as a time-varying energy source as in our case, these solutions exist only for simple functions such as steps, ramps, or simple deterministic variations.
