eLife, 2016 During continuous speech, lip movements provide visual temporal signals that facilitate speech processing. Here, using MEG we directly investigated how these visual signals interact with rhythmic brain activity in participants listening to and seeing the

The generalized shrinkage estimator for the analysis of functional connectivity of brain signals
, 2011 We develop a new statistical method for estimating functional connectivity between neurophysiological signals represented by a multivariate time series. We use partial coherence as the measure of functional connectivity.

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 ...

Exact Recovery Conditions for Sparse Representations with Partial Support Information [PDF]
, 2013 We address the exact recovery of a k-sparse vector in the noiseless setting when some partial information on the support is available. This partial information takes the form of either a subset of the true support or an approximate subset including wrong

Revivals of Coherence in Chaotic Atom-Optics Billiards
, 2003 We investigate the coherence properties of thermal atoms confined in optical dipole traps where the underlying classical dynamics is chaotic. A perturbative expression derived for the coherence of the echo scheme of [Andersen et. al., Phys. Rev. Lett. 90,

Generation of J0 Bessel Beams with controlled spatial coherence features
, 2010 An alternative method to generate J0 Bessel beams with controlled spatial partial coherence properties is introduced. Far field diffraction from a discrete number of source points on an annular region is calculated.

Superresolution of two unbalanced point sources assisted by the entangled partner
Physical Review Research, 2022 Sub-diffraction-limit resolution, or superresolution, has been successfully demonstrated in recent theoretical and experimental studies for two equal-brightness and incoherent point sources.

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 ...
