Besinc Pseudo-Schell Model Sources with Circular Coherence

open access: yesApplied Sciences, 2019
Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy.

Consensus-Related Performance of Triplex MASs Based on Partial Complete Graph Structure

open access: yesEntropy, 2022
This article mainly studies first-order coherence related to the robustness of the triplex MASs consensus models with partial complete graph structures; the performance index is studied through algebraic graph theory.

Partially Coherent Direct Sum Channels [PDF]

open access: yesQuantum, 2021
We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditions to identify the subset of those maps which are degradable, and provide a simplified expression for their quantum capacities.

Singularities of Partially Polarized Vortex Beams

open access: yesFrontiers in Physics, 2020
Singularities in the polarization state of non-uniform electromagnetic beams have been a topic of both theoretical and practical interest for many years, as have singularities in the correlation functions of random scalar wavefields.

Effects of partial coherence on frequency combs [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2007
We give an analytical model to study the deviations from an ideal frequency comb when the effects of random variations, from pulse to pulse, in the amplitude, phase, shape, chirp, and timing jitter are simultaneously taken into account.

Interference fringes with maximal contrast at finite coherence time [PDF]

open access: yes, 2002
Interference fringes can result from the measurement of four-time fourth-order correlation functions of a wave field. These fringes have a statistical origin and, as a consequence, they show the greatest contrast when the coherence time of the field is ...

Electrophysiological Correlates of Morphological Neuroplasticity in Human Callosal Dysgenesis. [PDF]

open access: yesPLoS ONE, 2016
In search for the functional counterpart of the alternative Probst and sigmoid bundles, considered as morphological evidence of neuroplasticity in callosal dysgenesis, electroencephalographic (EEG) coherence analysis was combined with high resolution and

The Relationship between Perceived Social Support and Social in College Students: The Mediation of Sense of Coherence [PDF]

open access: yesSHS Web of Conferences, 2021
This study aims to explore the relationship between the basic characteristics of college students’ social anxiety and the perceived social support and sense of coherence, and further explore the mediating role of the sense of coherence between perceived ...

Partial wavelet coherence as a robust method for assessment of neurovascular coupling in neonates with hypoxic ischemic encephalopathy

open access: yesScientific Reports, 2023
In neonates with hypoxic ischemic encephalopathy, the computation of wavelet coherence between electroencephalogram (EEG) power and regional cerebral oxygen saturation (rSO2) is a promising method for the assessment of neurovascular coupling (NVC), which

Can Global Economic Policy Uncertainty Drive the Interdependence of Agricultural Commodity Prices? Evidence from Partial Wavelet Coherence Analysis

open access: yesComplexity, 2021
This paper employed wavelet coherence and partial wavelet coherence to investigate the time-frequency effect of global economic policy uncertainty on the comovement of five agricultural commodities such as maize, oat, rice, soybean, and wheat using ...
