Pattern avoidance in partial permutations [PDF]
, 2011 Motivated by the concept of partial words, we introduce an analogous concept of partial permutations. A partial permutation of length n with k holes is a sequence of symbols $\pi = \pi_1\pi_2 ...

Effects of partial coherence on frequency combs [PDF]
Journal 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.

Partially Coherent Direct Sum Channels [PDF]
Quantum, 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.

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

Coherence methods in mapping AVO anomalies and predicting P-wave and S-wave impedances [PDF]
, 2005 Filters for migrated offset substacks are designed by partial coherence analysis to predict ‘normal’ amplitude variation with offset (AVO) in an anomaly free area.

Scientific 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 partial coherence interferometry be used to determine retinal shape? [PDF]
, 2011 Purpose: To determine likely errors in estimating retinal shape using partial coherence interferometric instruments when no allowance is made for optical distortion. \ud \ud Method: Errors were estimated using Gullstrand’s No.

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.

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