Oddly enough, even though congruent numbers are easy to define, spotting them or even estimating how many there are isn't so simple.
Whereas this study used positional information predefined in the system (gene expression networks from a spatially localized source), an arguably more sophisticated approach is to use reaction diffusion-type mechanisms (e.g. Tureaction diffusion-type1952) to define spots and stripes of gene expression.
A defined spot on the map of humanity.
Deposition of the cell also required careful control over fluid volumes, and the time cost to accurately deposit the cell on the defined spot with the PID control scheme was ∼9 seconds.
It was thought that variables such as these might affect spot quality (i.e. size and density) and so lead to differences in spot number when software settings are such that they discriminate between a large fuzzy spot and a small well defined spot.
The irregular distributions of the pixels contributing to the signal of one of the artificial glomeruli, which then serves the purpose of a well defined spot, i.e. the summary of pixels with similar properties, resemble much better the zonal- and distributed nature of ORNs in the olfactory epithelium.
After visual inspection, one spot from the FTC PTC model (spot number 0401, data not shown) was excluded from the investigation, as this was an elongated, vaguely defined spot very close to the precipitation line at the acidic edge of the 2-DE gel, rendering any further analysis unreliable.
For example, clouded leopards, a critically endangered species with less defined spots, pair up with their mates early in life.
Well defined spots were obtained when the chamber was saturated with the mobile phase for 10 min at room temperature.
