Spectrum Sensing Based on Higher Order Cumulants and Kurtosis Statistics Tests in Cognitive Radio [PDF]

Radioengineering, 2019
In this paper, new algorithms for spectrum sensing in cognitive radio based on higher order cumulants and kurtosis are proposed. The cumulants represent statistical signal processing based on pattern recognition for signals of different structure, and ...

Least Trimmed Squares: Cointegration and Outliers

Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 690-711, August 2026.
ABSTRACT When applying the cointegrated autoregressive distributed lag model it is common to include indicator variables for outliers. This is often done in a somewhat ad hoc way. Least Trimmed Squares estimation provides a more systematic approach. This estimator is robust to a large number of outliers of many types.

Non-uniform Estimates in the Approximation by the Irwin Law

Lithuanian Journal of Statistics, 2016
We consider an approximation of a cumulative distribution function F(x) by the cumulative distributionfunction G(x) of the Irwin law. In this case, a function F(x) can be cumulative distribution functions of sums (products) ofindependent (dependent ...

Development of a Lensless Compact Optical System for Ultrasensitive Nanomaterial Detection in Liquid Media via Exploiting Multiple Light Scattering

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
This work presents a lensless speckle‐based platform that exploits multiple light scattering for precise nanoparticle detection in liquid media. The proposed method enables ultrasensitive detection at concentrations far below conventional DLS limits and provides semiquantitative size estimation, offering a cost‐effective and field‐deployable approach ...

Baselines for Abelian charge fluctuations in nuclear collisions:theory and comparison with experimental data

Journal of High Energy Physics
We investigate fluctuations in the canonical ensemble of an Abelian charge, such as baryon number. Our focus is on cumulants and factorial cumulants of baryon and antibaryon multiplicity distributions, including their sum and difference, in both the full

Inverse counting statistics for stochastic and open quantum systems: the characteristic polynomial approach

New Journal of Physics, 2014
We consider stochastic and open quantum systems with a finite number of states, where a stochastic transition between two specific states is monitored by a detector.

Implementing Cumulative Functions with Generalized Cumulative Constraints

CoRR
Modeling scheduling problems with conditional time intervals and cumulative functions has become a common approach when using modern commercial constraint programming solvers. This paradigm enables the modeling of a wide range of scheduling problems, including those involving producers and consumers.

Factorial cumulants of proton multiplicity near a critical point using maximum entropy freeze-out prescription [PDF]

EPJ Web of Conferences
We present the first application of the maximum-entropy freeze-out prescription to calculate factorial cumulants of proton multiplicities near the conjectured QCD critical point in thermal equilibrium.

Explaining higher-order correlations between elliptic and triangular flow

Physics Letters B
The ALICE and CMS Collaborations have analyzed a number of cumulants mixing elliptic flow (v2) and triangular flow (v3), involving up to 8 particles, in Pb+Pb collisions at the LHC.
