Addressing indirect frequency coupling via partial generalized coherence
Scientific Reports, 2021 Distinguishing between direct and indirect frequency coupling is an important aspect of functional connectivity analyses because this distinction can determine if two brain regions are directly connected.

Partial coherence and coherence length in StimPDC
, 2023 In parametric down conversion, a nonlinear crystal is pumped by a laser and spontaneous emission takes place in signal and idler modes according to the phase matching conditions. A seed laser can stimulate the emission in the signal beam if there is mode overlap between them.

Gait-based human recognition using partial wavelet coherence and phase features
Journal of King Saud University: Computer and Information Sciences, 2020 In this paper, a multi-view human gait recognition method which utilizes Partial Wavelet Coherence (PWC) as a novel feature is proposed. The Euclidean distance representation of PWC of the 1D signals generated due to movements of hands, legs, shoulders ...

Three-dimensional analysis of prebunched electron beams in an x-ray free-electron laser
Physical Review Special Topics. Accelerators and Beams, 2012 The effect of partial prebunching of an electron beam on the saturation length, efficiency, and longitudinal coherence is studied for a nominal x-ray free-electron laser design.

Partially-coherent waves with binominal coherence
, 2022 Comprehensive analysis of non-diffracting optical waves with binominal two-point coherence function (BCF) is presented. This coherence function consist of two terms, each depending on either separation of points or central point. We established the necessary and sufficient conditions for non-negative definiteness of the binominal coherence functions ...
