Localization of mixed‐field sources based on fourth‐order cumulant matrix rank reduction
Electronics Letters, 2023 In this letter, a localization algorithm for mixed‐field sources based on fourth‐order cumulant matrix rank reduction is proposed. First, a cumulant matrix is constructed, and a spectral peak search function associated with the direction‐of‐arrival (DOA)

Status Recognition of Magnetic Fluid Seal Based on High-Order Cumulant Image and VGG16
Frontiers in Materials, 2022 A magnetic fluid seal is often used in complex working conditions with harsh environmental requirements. Timely and accurate identification of the seal status can help avoid the major economic losses and even casualties caused by the seal failure ...

Entropy, 2020 A major challenge in neuroscience is to understand the role of the higher-order correlations structure of neuronal populations. The dichotomized Gaussian model (DG) generates spike trains by means of thresholding a multivariate Gaussian random variable ...

Direction-of-Arrival Estimation Based on Sparse Representation of Fourth-Order Cumulants
IEEE Access, 2023 The actual underwater environmental noise is often spatial colored, which results in severe degradation of the performance of the underwater direction of arrival (DOA) estimation method based on the assumption of white noise.

QCD Critical Point and Net-Proton Number Fluctuations at RHIC-STAR [PDF]
EPJ Web of Conferences, 2022 In the search of QCD phase boundary and critical point, higher-order cumulants of conserved quantities are proposed as promising observables and have been studied extensively both experimentally and theoretically. In this paper we present cumulant ratios

Idiosyncratic Risk and Higher-Order Cumulants [PDF]
SSRN Electronic Journal, 2011 We show that, when allowing for general distributions of dividend growth in a Lucas economy with multiple \trees," idiosyncratic volatility will aect expected returns in ways that are not captured by the log linear approximation. We derive an exact expression for the risk premia for general distributions.

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

Ott-Antonsen ansatz truncation of a circular cumulant series
Physical Review Research, 2019 The cumulant representation is common in classical statistical physics for variables on the real line and the issue of closures of cumulant expansions is well elaborated. The case of phase variables significantly differs from the case of linear ones; the

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