WebJan 7, 2014 · Fold-change detection with specificity and repeatability) As stated above, when the input is smoothly changing, the previous log-differentiator type models cannot achieve fold-change detection with specificity and repeatability (srFCD). Nevertheless, as stated before, such detection by cells is reported in real biological situations (10 ... WebMar 4, 2013 · Fold-change detection means that the system responds to fold (relative) changes in the input rather than the input’s absolute levels – at least over a range of several decades of input signal strength. Thus, a step change in input levels from 1 to 2 and a step from 2 to 4 results in precisely the same response dynamics, including amplitude ...
Cellular Sensory Mechanisms for Detecting Specific Fold-Changes …
WebThe fold change is a measure of how much the copy number of a case sample differs from that of a normal sample. When the copy number for both the case sample and the normal sample is 2, this corresponds to a fold change of 1 (or -1). The sample fold change can be calculated from the normal copy number and sample copy number. WebThe present work demonstrated that, in the social amoeba Dictyostelium, a response to cell–cell communication molecules is fold-change dependent and that this property is … poai share price today
