Cells moving without persistence need a chemotaxis bias for each new pseudopod, while cells moving persistently will accumulate directional accuracy at each subsequent pseudopod.
Chemotaxis may represent another field of cell biology where persistence could be critical, because cells moving without persistence need a chemotaxis bias for each new pseudopod, while cells moving persistently will accumulate directional accuracy at each subsequent pseudopod.
This property to move persistently along walls enabled us to design patterns that control direction of movements, resulting in uni-directional circling or one-way gating between two areas.
In the cases of both Spain and Italy debts that appear sustainable at interest rates of 3-4% become unsustainable if rates move persistently to 6-7%, making it rational for investors to keep selling bonds even as they get cheaper.
However, the tail eventually retracted in most cases, allowing the cell to move persistently (Movies S10, S11, S12).
Addition of Y-27632 during the acquisition of timelapse movies inhibited membrane blebbing and successfully re-established stable uropods in nocodazole-treated cells, allowing cells to move persistently in one direction (Figure 6D, indicated with white arrows, Movies S8 and S9).
In theory, without performing interbody fusion, the residual disc would move persistently, reduce the PLF rate, and possibly engender a less satisfactory result.
Wages moved up more persistently in the 60's as the unemployment rate fell.
Hindsight is, of course, 20/20, but we cannot help noting that if Barker had moved immediately and persistently for a speedy trial following indictment, and if he had been successful, he would have undoubtedly been acquitted since Manning's testimony was crucial to the Cmmonwealth's case.
