This is small, but may be observable using today's best observational system.
Such samples make it possible to assess whether population genetic diversity has declined and genetic structure has increased and to explore demographic scenarios that best explain observable genetic patterns (Johnson et al. 2004; Martinez-Cruz et al. 2007).
For example, p90Rsk phosphorylation on Ser380 and phosphorylation of JNKs is at best barely observable in high serum culture (figure 3C and 3D; compare to additional files 3 and 5).
A common procedure for TCAR is, given three frequencies, to identify the three best combination observables to allow for more reliable AR under the given observational conditions characterized by the magnitudes of atmospheric conditions, phase noise and orbital error etc.
Sensitivity analysis is often embedded in design of experiment schemes to identify network interactions which best manipulate the observable outputs [ 19].
I have a constant problem because I'm always having to circumvent what the camera does best, which is reproduce observable reality.
For the purposes of this argument, 'atoms' may be understood as a placeholder for whichever microscopic objects or stuff feature in the best microphysical explanations of observable reality.
We accept the existence of electrons because our best theories of the observable phenomena associated with electricity and atomic structure crucially depend on the hypothesis that there are electrons.
Or, as Hoffmann puts the point: "[I]f understanding is sought, simpler models, not necessarily the best in predicting all observables in detail, will have value.
