Fold-change detection

WebDefinition of fold change detection (FCD) Let’s define what we mean by sensing relative changes more precisely. We want the entire shape of the output curve to depend only on … Webfold-change detection mechanism can address this problem: it allows detection of a signal that changes by 0.3 above a back-ground of 1 but obtains a similar response only to changes of 3 above a background of 10. Fold-change detection, therefore, assigns meaning to asignal in reference to the background signal level, allowing responses

WebApr 11, 2014 · This indicates that an increased template ratio [TrMG tot]/[TiMG tot] moved the system away from the parameter regime where an approximate fold-change detection can be observed. On the other hand, the simulation result still showed an approximate fold-change detection for the final input perturbation (Figure (Figure5F 5F).

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.
