Frontiers in Neurology, 2021 Over the last decade, several methods for analysis of epileptiform signals in electroencephalography (EEG) have been proposed. These methods mainly use EEG signal features in either the time or the frequency domain to separate regular, interictal, and ...

Interaction induced phase fluctuations in a guided atom laser
, 2002 In this paper, we determine the magnitude of phase fluctuations caused by atom-atom interaction in a one-dimensional beam of bosonic atoms. We imagine that the beam is created with a large coherence length, and that interactions only act in a specific ...

Attentional modulation of inter-areal coherence explained by frequency shifts
NeuroImage, 2023 Inter-areal coherence has been hypothesized as a mechanism for inter-areal communication. Indeed, empirical studies have observed an increase in inter-areal coherence with attention.

The Role of the Short Coherence Length in Unconventional Superconductors
Condensed Matter, 2020 A short coherence length is a distinctive feature of many cases of unconventional superconductivity. While in conventional superconductors, it is many orders of magnitude larger than the basic inter-particle distance, a short coherence length is common ...

Journal of Marine Science and Engineering, 2023 The presence of wave coherence, which contributes to the inhomogeneity of wave characteristics and significantly affects wave processes over nearshore regions of the Yellow River Delta (YRD), was simulated and analyzed in this study.

Non-Coherent Direction of Arrival Estimation from Magnitude-Only Measurements [PDF]
IEEE Signal Processing Letters, 2015 We consider the classical Direction of arrival (DOA) estimation problem in the presence of random sensor phase errors are present at each sensor. To eliminate the effect of these phase errors, we propose a DOA recovery technique that relies only on magnitude measurements.

Coherent energy migration in solids: Determination of the average coherence length in one‐dimensional systems using tunable dye lasers [PDF]
, 1976 The coherent nature of energy propagation in solids at low temperatures was established from the time resolved response of the crystal to short optical pulses obtained from a dye laser (pumped by a nitrogen gas laser).

SAR Coherence Estimation by Composition of Subsample Estimates and Machine Learning
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingSynthetic aperture radar (SAR) coherence magnitude is an essential parameter in SAR interferometry. This is the reason why current interferometric wide area ground motion services require the estimation of the coherence magnitude as accurately and ...

Multi-shaping technique reduces sidelobe magnitude in optical coherence tomography
Biomedical Optics Express, 2017 Shaping methods that are commonly used in Fourier-domain optical coherence tomography (FD-OCT) can suppress sidelobe artifacts in the axial direction, but they typically broaden the mainlobe of the point spread function (PSF) and reduce the axial resolution. To improve OCT image quality without this tradeoff, we have developed a multi-shaping technique
