Even when measurements of the steady state compositions are fragmentary, the theory will sometimes indicate that a candidate network which does admit multiple steady states will nevertheless be unable to account for the particular measurements made.
Changes in composition may occur over time, but the system always seems to return to a time-averaged, steady-state composition.
The steady-state composition was achieved typically after depositing a 90-nm-thick alloy layer.
In addition, the obtained specific steady-state composition of the surface varied significantly with alloy combination and particle diameter.
We can therefore anticipate a uniform steady-state composition of hydrocarbons at catalytic sites reflecting equivalent rates of hydrocarbon delivery and removal and changing compositions at catalytic sites under static conditions.
The relative amount of gas exchange through the non-selective membrane can be adjusted by varying the volumetric air feed rate to its upstream surface; this will, in turn, adjust the steady-state composition of the gas around the produce.
Intriguingly, using the rates of D ( = once per 10 days) and F ( = once per 20 days per bridge) inferred from live imaging, the model faithfully recapitulated the steady-state composition of GFRα1+ spermatogonia measured in vivo.
Hence, addition of ATP, lipids, and actin to the system alter the steady-state composition of the phagosomal membrane at the same time that the actin nucleation is initiated.
This model could predict the range of complex data obtained from independent measurements, from the steady-state composition of GFRα1+ units to the wide range of intricate clonal fate behaviors of pulse-labeled GFRα1+ cells, both in steady state and in regeneration.
PCho may also be derived from PC catabolism through phospholipase C, yielding diacylglycerol and PCho, or from recycling of GPCho, which is the product of PC deacylation by phospholipase B. Both reactions contribute to the remodeling of phospholipids, a process that is required to maintain the correct steady-state composition of PL species and their acyl-chain distribution (Fig. 2).
