Higher Order Cumulants and Inference for a Class of Filtered Poisson Processes
Austrian Journal of Statistics, 2016 Spectral methods are useful in the analysis of time series and point process data in Zd or Rd. Parameter estimates based on these often have a limiting Gaussian distribution, whose limiting variance depends upon integrals of the second, third and fourth ...

Improved resolving capabilities of linear array using 2qth order non‐circular statistics
IET Signal Processing, 2021 Resolving more sources than sensors is always of interest to researchers. For this purpose, generation of the virtual array from the non‐uniform linear array has recently gathered a lot of attention.

Krylov complexity in large q and double-scaled SYK model
Journal of High Energy Physics, 2023 Considering the large q expansion of the Sachdev-Ye-Kitaev (SYK) model in the two-stage limit, we compute the Lanczos coefficients, Krylov complexity, and the higher Krylov cumulants in subleading order, along with the t/q effects.

Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Automatic Modulation Classification of Real Signals in AWGN Channel Based on Sixth-Order Cumulants [PDF]
Radioengineering, 2021 Automatic modulation classification (AMC) represents an important integral part of modern communication systems. While novel AMC algorithms based on complex neural network structures showed significant performance improvements, in practical applications ...

On the Cumulants of the First Passage Time of the Inhomogeneous Geometric Brownian Motion
Mathematics, 2021 We consider the problem of the first passage time T of an inhomogeneous geometric Brownian motion through a constant threshold, for which only limited results are available in the literature.

Linear Causal Disentanglement via Higher-Order Cumulants
La MatematicaAbstract Linear causal disentanglement (LCD) is a recent method in causal representation learning to describe a collection of observed variables via latent variables with causal dependencies between them. It can be viewed as a generalization of both independent component analysis and linear structural equation models.

Higher order pion interferometry. Moments and cumulants
Physics Letters B, 1993 Abstract Pion interferometry can be viewed as intermittency analysis in terms of momentum transfer of like-sign particles. By putting the common practice of event mixing on a sound footing and extending its use, we provide the tools to eliminate the combinatoric background contained in the usual correlation functions. Information on true higher order

Advanced Science, EarlyView.This study shows that amyloid fibrils form nematic condensates via liquid–liquid crystalline phase separation (LLCPS). With increasing pH, this transition shifts toward disordered condensates formed through liquid–liquid phase separation (LLPS), in which birefringence with lack of a coherent nematic field symmetry originates from enthalpic fibril ...
