Cross-correlation分析
WebApr 13, 2024 · Cross-correlation is a common signal processing used as a similarity measure through the comparison between time series as a function of the displacement of one with respect to the other. However, this signal processing must be applied to compare two images [ 37 ], in this case, called “2D-cross-correlation” (CC) [ 38 ].

WebOct 8, 2008 · Here we show by applying fluorescence correlation and cross-correlation spectroscopy (FCS/FCCS) in vivo that two distinct RISC exist: a large ∼3 MDa complex in the cytoplasm and a 20-fold smaller complex of ∼158 kDa in the nucleus. We further show that nuclear RISC, consisting only of Ago2 and a short RNA, is loaded in the cytoplasm … WebOverview: Cross Correlation. In some processes, a lag occurs between a change in a field value and the effect seen on the process target field. When the optimal lag is calculated, there is the highest correlation between the change in one field and the effect seen on another field. Use this operation to automatically calculate the lag required ...
Web8.2 Cross Correlation Functions and Lagged Regressions. The basic problem we’re considering is the description and modeling of the relationship between two time series. In the relationship between two time series ( y t and x t ), the series y t may be related to past lags of the x -series. The sample cross correlation function (CCF) is ...
