Stationary Points of a Kurtosis Maximization Criterion for Noisy Blind Source Extraction
IEEE Access, 2017 Blind source extraction (BSE) is often posed as the maximization of a statistical criterion under a unitary constraint. This paper addresses the convergence problem of a kurtosis-based criterion in the presence of noise.

Denoising Using Blind Source Separation for Pyroelectric Sensors
EURASIP Journal on Advances in Signal Processing, 2001 This paper deals with a process of denoising based on a Blind Source Separation (BSS) method. This technique is inserted in an experimental device of nondestructive testing. Its excitation is a laser beam and its detectors are pyroelectric sensors.

Penalty Function Approach for Constrained Convolutive Blind Source Separation
, 2004 A new approach for convolutive blind source separation (BSS) using penalty functions is proposed in this paper. Motivated by nonlinear programming techniques for the constrained optimization problem, it converts the convolutive BSS into a joint ...

Short-Sampled Blind Source Separation of Rotating Machinery Signals Based on Spectrum Correction
Shock and Vibration, 2016 Nowadays, the existing blind source separation (BSS) algorithms in rotating machinery fault diagnosis can hardly meet the demand of fast response, high stability, and low complexity simultaneously.

Precoding-Based Blind Separation of MIMO FIR Mixtures
IEEE Access, 2017 This paper focuses on the problem of blind separation of sources mixed by multi-input multi-output finite impulse response channels, which is also called convolutive blind source separation (BSS) in short. This problem has been intensively studied in the

Cross‐Entropy of Power Spectral Density Function: A Modal Identification Framework
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 12, Page 3012-3028, 10 October 2026.ABSTRACT The power spectral density (PSD) function of measured structural response contains a significant amount of information, including the modal parameters (natural frequencies, damping ratios). Output‐only system identification or modal identification technique can be used for extracting such modal parameters from the measured response or its ...

Single-channel blind source separation of underwater acoustic signals using improved NMF and FastICA
Frontiers in Marine Science, 2023 When automatic monitoring buoys receive mixed acoustic signals from multiple underwater acoustic targets, the statistical blind source separation (BSS) task is used to separate the signals and identify vessel features, which is overly complex and needs ...

MedComm, Volume 7, Issue 10, October 2026.Our study reveals a novel mechanism by which MSC‐derived EVs alleviate NaIO3‐induced dry AMD‐like pathology. MSC‐EVs deliver miR‐486‐3p into retinal cells to directly inhibit the ferroptosis‐promoting target gene Lcn2. Concurrently, downregulated Lcn2 restores intracellular Gpx4 expression, thereby suppressing ferroptosis and rescuing retinal ...
