Example: "The effects of the treatment are not observable at this early stage of the study."
Alternatives: "cannot be seen at" or "are not visible at".
In this context they potentially fulfill a twofold function: as productive assets and, likely, as signals of characteristics of a venture that are not observable at the time of assessment.
These transient changes, which are not observable at steady state, may lead to important in vivo responses.
At the meso level however, relationships which are not observable at the micro level can be analyzed [ 24].
In many contest situations, the number of participants is not observable at the time of investment.
The analytical results reveal macroscopic behavior (vulnerability) derived from the diffusion of excitation that is not observable at the level of isolated cells or single reaction units.
Remote sensing can expose the information that is not observable at ground in remote areas (Blumberg 1998; Dabbagh et al. 1997).
Contrarily, nuclear translocation of wild-type and truncated proteins were not observable at 10 hr post-microinjection.
The same principle seems to be reflected in the YMC, although it is not observable at the level of detail investigated e.g. in [ 44], but more macroscopically and at genome-wide level.
This supports the hypothesis that the identified MdPME2 might locally change the pectin properties in a way that is not observable at a whole fruit scale but only locally.
Enumeration of PCC breaks in G2-phase chromosomes confirmed a repair defect in Artemis- and Brca2-deficient cells at 4 and 6 h, which is not observable at 1 h following 1-Gy IR treatment, a phenotype consistent with the analysis of γH2AX foci.
We use a Markov Switching Autoregressive (MS-AR henceforth) model, which allows us to identify and characterize a non-linear behavior.3 A MS-AR model assumes that switching regimes that occur at time t are not observable, whose process is denoted by (S_t ).
