Functional relations for higher-order free cumulants

open access: yes, 2021
We establish the functional relations between generating series of higher-order free cumulants and moments in higher-order free probability, solving an open problem posed fifteen years ago by Collins, Mingo, Śniady and Speicher. We propose an extension of free probability theory, which governs the all-order topological expansion in unitarily invariant ...

Application of Higher Order Cumulants for Seismic Wavelet Reconstruction

open access: yesData Science Journal, 2007
According to the fact that high order cumulants (HOC) retain the phase information of signals and the HOC of the Gaussian color noise is always equal to zero, a new method of wavelet reconstruction is provided in this paper, based on 4th-order cumulants ...

An array virtual extension method for power equipment acoustic emission direction of arrival estimation based on high‐order cumulants

open access: yesHigh Voltage, 2021
The performance of array‐based power equipment acoustic emission (AE) source directional of arrival (DOA) estimation methods is decided by not only algorithm performance, but also the array hardware parameters, that is, array aperture, sensor number, and

Local efficiency corrections to higher order cumulants

open access: yesPhysical Review C, 2015
In this brief note we derive and present the formulas necessary to correct measurements of cumulants for detection efficiency. In particular we consider the case where the efficiency may depend on the phase-space, such as transverse momentum, rapidity etc.

Volume fluctuation and multiplicity correlation in higher-order cumulants [PDF]

open access: yesPhysical Review C, 2019
Initial volume fluctuation (VF) arising from the participant fluctuation would be the background which should be subtracted experimentally from the measured higher-order cumulants. We study the validity of the Volume Fluctuation Correction (VFC) on higher-order net-proton cumulants by using simple toy model and UrQMD model in Au+Au collisions at \sqrt ...

Blind Identification and Equalization of MC-CDMA Systems Using Higher Order Cumulants

open access: yesInternational Journal of Advances in Telecommunications, Electrotechnics, Signals and Systems, 2014
In this work we propose an algorithm based on fourth order cumulants for identification of the linear system (Finite- Impulse Response (FIR)) with Non Minimum Phase (NMP) excited by non-Gaussian sequences, independent identically distributed (i.i.d).

Research on Series Arc Fault Detection Based on Higher-Order Cumulants

open access: yesIEEE Access, 2019
At present, the detection methods on series arc faults are mainly based on the current of the main circuit, which probably results in misjudgment because of the singularity of the normal working current in a nonlinear load.

Effect of dephasing on the current statistics of mesoscopic devices [PDF]

open access: yes, 2004
We investigate the effects of dephasing on the current statistics of mesoscopic conductors with a recently developed statistical model, focusing in particular on mesoscopic cavities and Aharonov-Bohm rings.
