Transmission of signals, whether on-chip or off-chip, places severe constraints on timing and extracts a large price in energy.
The isotope record from pedogenic carbonates provides a direct record of climatic change, suggesting that long-term carbon isotope data can provide useful constraints on timing and intensity of regional desertification, and its associated climate and topographic interaction.
Their skepticism is shared by many tea party Republicans and others, whose views range from ideological opposition to any U.S. military action overseas to narrower fears about authorizing the use of force without clear constraints on timing, costs and scope of the intervention.
Although the dual-control task did not impose specific constraints on timing of the two control processes, the lack of interference is unlikely to be explained by sequential engagement of explicit and implicit control.
To test for timing robustness, our approach was to begin with a fully asynchronous model in each case, examine the cases where the models fail to be robust, and either change the model or introduce additional constraints on timing (making the model less-than-fully asynchronous) as necessary.
There are no constraints on timing, because samples can be held at many points for as long as necessary with no adverse effects, including the initial fixative stage and the final staining stage.
That might depend on timing.
It all depends, of course, on timing.
