The minimum number of landmarks k required for self-location depends on the types of measurements the robot can perform, such as visual angles using a video camera on a pan-tilt unit, distances using a laser range finder, or absolute orientation using a compass.
The previous observations that both MglA and MglB bind in a bipolar pattern in the absence of the other or in case of an impaired MglA GTPase activity in the case of MglAR53A, MglAQ82A and MglBA64/R68R have important implications: First, these observations suggest that landmark proteins required for polar binding of MglA and MglB are present at both poles at the same time.
Although arbitrary, fiat boundaries nevertheless may be determined by specific (bona fide) landmarks or coordinates, which are required for reliably re-locating fiat boundaries; [19], [20], [22], or other pragmatic or even scientifically justified reasons.
Most of these patients had early progression or death and were excluded to meet the conditions required for a landmark analysis [ 14, 15], i.e., to avoid bias in favour of responders.
In this study the authors focused on the use of two landmarks as this is the minimum required for validation of this approach.
Due to the absence of fixed, recognizable structures in root system (that are required for the position of true landmarks), pseudo-landmarks are automatically extracted from the root systems.
A statement released by the New York City Landmarks Preservation Commission on Tuesday said that the building lacked the "historical and architectural integrity required for individual New York City landmark designation".
The building was designated a landmark in 1973, and Landmarks Preservation Commission approval is required for any exterior work, Mr. Papadatos said.
Our data demonstrate that in cells where polarity landmarks are present, the actin cytoskeleton is not required for the first steps of polarized growth upon exit from quiescence.
