In some sawmills (and other wood-using industries) computers are employed to regulate positioning of logs and other operations.
COTS electronics and a capacitance-to-voltage IC are used to develop a closed-loop controller for the system, capable of regulating position over a range of about 40 μm to within a 5 nm resolution and controlling forces up to 300 μN with a resolution of 25 nN.
Wnt signalling helps to maintain an undifferentiated state of the intestinal stem cells [16], [17] and, paradoxically, also regulates positioning, differentiation and maturation of Paneth cells [13], [18].
Our present results provide additional evidence for at least two other levels of control that regulate positioning and activity of crossover events, confirming prior results in mice [2] and humans [45], [46], one at a megabase-scale which we consider a regional level of control, and another at the positioning of individual hotspots which we consider a local level of control.
In higher eukaryotes, the epigenome is much more complex as at least four different forms of cytosine can occur and dynamically interconvert at epigenetically regulated genomic positions.
The number of transcripts differentially regulated by position within individual colonies (n = 2215) is of the same magnitude as differences between the two species (n = 2288).
If we consider Euclidean geometry we clearly discern that it refers to the laws regulating the positions of rigid bodies.
The control objective is to regulate the positions of two match motors to the desired ones.
Unlike ATH1 and BOP1/BOP2, which are required for some or all of the floral organ abscission zones to form [ 8],[ 9], AS1 and BP appear to play a more indirect role in abscission zone specification by regulating their positions.
Although TSSs for TATA promoters are often fixed to single positions, our results suggest that such strictly controlled positions of TSSs are not regulated by nucleosome position.
