4) spectral density function 谱密度函数 1. According to Taylor s Frozen Assumption about turbulence, an analytical solution of spectral density function of pressure fluctuation in across-wind direction was derived from the governing equation of flow movement in turbulence theory. 从湍流理论的基本...
The equation for free-space propagation of the generalized radiance defined formerly by the authors in terms of the coherent-mode representation of the cross-spectral density function is derived within the accuracy of the paraxial approximation. It is shown that, in the short-wavelength limit, this...
However, the evaluation presents an opposing H1 hypothesis, suggesting that there is a causal connection based on findings from at least one cross-sectional study. Equation (25) is a valuable tool that utilizes the D-H diagram. The D-H causality test is expressed in Eq. (25), where Y re...
Where Sjj(f) is the cross-spectral density. The coherence of the loading is very useful if the two components of the response have the same natural frequencies, which is in many cases correct for the overturning moments, but the natural frequency of the torsional response is often higher. Fi...
The gene coexpression coefficient ΔCRNA(i,j) between two ACDs within the same chromatin was estimated by using the following equation: $${\Delta C}_{{\rm{RNA}}}(i,j)=\frac{{n}_{\Delta {\rm{S}}+}-{n}_{\Delta {\rm{S}}-}}{{n}_{\Delta {\rm{S}}+}+{n}_{\Delta {...
such as a crosslink-specific equation for calculating FDR15,16. Two additional considerations have been suggested for correctly estimating errors in crosslinking-based PPI screens. The first, whether to consider crosslinks between peptides within one protein sequence (self-links, including homomeric cro...
In the case of discreet measurements with pixel dimensions x and y , M and N pixels in the tangential and sagittal directions, respectively, the 2D PSD distribution can be evaluated from the height distribution h m , n via equation S 2 ( l , k ) = M N x y F l , k 展开 ...
Equation 1 is added to the learning-to-rank objective function to enforce sparse representations during learning. (Ψ|Ω) = ( |0, 2) ( 2| , ) = ∏ ( |0, 2 ) ∏ − ( 2 | , ); (1) where = ( 1, 2, … , ) is a parameter vector of fea- tures, is the number of ...
Spectral counts were used to estimate abundance changes. The cross-linked residue pairs were classified into three K-means clusters. “N” means that the cross-link did not make the cutoff for identification in the experiment of Fig. 7d. Cross-linking residue pairs were filtered by requiring ...
(Fig.1h). Accurate FRET efficiencies E can then be converted into distances r using the Förster equation (Fig.1i), which requires knowledge of the Förster radiusR0(inter-probe distance withE = 0.5). An overview of correction parameters for conversion of setup-dependent to accurate ...
