Once each supercontinent is assembled, it undergoes back-and-forth rotations about a stable axis on the Equator, Mr. Mitchell said.
Therefore, the design of the wt MglA/MglB polarity system accommodates both a stable polarity axis (between reversals) that depends on regulation of MglA GTPase activity by MglB, and a dynamic polarity axis that depends on Frz activity.
It happens to have a stable rotational axis because, miraculously, it's got a big moon that stabilises the axial position," says Richard Taylor, a fellow of the British Interplanetary Society.
The designed quarter wave plate shows phase retardance of 90°±3° with a stable optical axis.
The WLT assesses skill in identifying a stable horizontal axis in spite of a conflicting visual context (Piaget & Inhelder, 1956).
AspC induced atypical pseudohyphae in bnr1Δ showing that a stable mother/bud axis is not required for filament formation.
Thus, the mutually exclusive localization of MglA and MglB sets up a stable polarity axis, which can be dynamically inverted in response to Frz activity.
Algorithmically, ChIPS does this initially by keeping the x-axis as the stable axis and adjusting the y axis limits around it.
"There is political uncertainty, crime, violence... I was concerned about having a stable future for my children," Neugarten explained.
However, the terms in Equation (2) describe alignment with a stable direction (not axis), which is a vectorial symmetry.
In vivo analyses demonstrate that MglA GTPase activity and MglB GAP activity is essential for maintaining a stable leading/lagging polarity axis that is only occasionally inverted.
