Blind source separation communication anti-jamming technology and practice

open access: yesTongxin xuebao, 2023
Aiming at the threat of broad frequency band suppressing jamming and the inherent contradiction between spectrum resources and communication anti-jamming ability, a method was proposed to add the statistics domain dimension on the basis of spread ...

Generalized independent low-rank matrix analysis using heavy-tailed distributions for blind source separation

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
In this paper, statistical-model generalizations of independent low-rank matrix analysis (ILRMA) are proposed for achieving high-quality blind source separation (BSS). BSS is a crucial problem in realizing many audio applications, where the audio sources

Equivalence between Frequency-Domain Blind Source Separation and Frequency-Domain Adaptive Beamforming for Convolutive Mixtures

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
Frequency-domain blind source separation (BSS) is shown to be equivalent to two sets of frequency-domain adaptive beamformers (ABFs) under certain conditions. The zero search of the off-diagonal components in the BSS update equation can be viewed as the

Vision outcomes in dogs with primary glaucoma surgically treated with lensectomy and endolaser cyclophotocoagulation after an Ahmed valve gonioimplantation failure

open access: yesVeterinary Ophthalmology, Volume 28, Issue 2, Page 207-217, March 2025.
Abstract Objective The aim of this study was to retrospectively evaluate vision outcomes of dogs with primary angle closure glaucoma (PACG) that underwent Ahmed valve gonioimplantation (AVG) followed by lensectomy and endolaser cyclophotocoagulation (ECP) with or without bleb resection after AVG failure.

Cross‐Entropy of Power Spectral Density Function: A Modal Identification Framework

open access: yesEarthquake 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 ...

Mesenchymal Stem Cell‐Derived Extracellular Vesicles Ameliorate NaIO3‐Induced Dry AMD by Delivering miR‐486‐3p to Inhibit Lipocalin‐2‐Mediated Ferroptosis

open access: yesMedComm, 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 ...

A Randomized Algorithm for Simultaneously Diagonalizing Symmetric Matrices by Congruence

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT A family of symmetric matrices A1,…,Ad$$ {A}_1,\dots, {A}_d $$ is simultaneously diagonalizable by congruence (SDC), also called nonorthogonal joint diagonalization, if there is an invertible matrix X$$ X $$ such that every XTAkX$$ {X}^T{A}_kX $$ is diagonal. In this work, a novel randomized SDC (RSDC) algorithm is proposed that reduces SDC to
