A Randomized Algorithm for Simultaneously Diagonalizing Symmetric Matrices by Congruence

Numerical 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

Enhancing Identifiable Variational Autoencoder in the Presence of Missing Values and Auxiliary Covariates for Spatio‐Temporal Ozone Modeling

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT The formation of ground‐level ozone follows complex nonlinear photochemical processes that depend on multiple environmental factors and have strong spatio‐temporal structures. Environmental data used to study these dynamics usually originate from multiple sources, including in situ monitoring stations and satellite observations.

Time-Domain Convolutive Blind Source Separation Employing Selective-Tap Adaptive Algorithms

EURASIP Journal on Audio, Speech, and Music Processing, 2007
We investigate novel algorithms to improve the convergence and reduce the complexity of time-domain convolutive blind source separation (BSS) algorithms. First, we propose MMax partial update time-domain convolutive BSS (MMax BSS) algorithm.

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

EURASIP 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

Radar Main-Lobe Jamming Suppression Based on Adaptive Opposite Fireworks Algorithm

IEEE Open Journal of Antennas and Propagation, 2021
In the presence of the main lobe jamming, the performance of the modern radar system would degrade significantly. In this study, a blind source separation (BSS) method based on an Adaptive Opposite Fireworks Algorithm (AOFWA) is proposed to address the ...

Validation of the Brief Solastalgia Scale (BSS‐Br): Psychometric evidence of environmental distress in the Brazilian population

Environmental Psychology Research, Volume 1, Issue 3, September 2026.
Abstract Background/Objective Environmental degradation increasingly drives psychological distress, yet no validated Portuguese‐language instrument exists to measure solastalgia, place‐based distress caused by environmental change. This study aimed to translate, culturally adapt and psychometrically validate the Brief Solastalgia Scale for Brazil (BSS ...

The separation algorithm for dynamic sources in the noisy case based on neural network

Dianzi Jishu Yingyong, 2018
In view of the dynamic sources in the noisy case, this paper proposes a novel online blind source separation(BSS) algorithm which contains two parts. One is a dynamic source number estimation algorithm based on Rissanen’s minimum description length(MDL).

Stem Cell‐Based Therapies for Skin Rejuvenation: A Systematic Review of Clinical Efficacy, Safety, and Underlying Mechanisms

Journal of Cosmetic Dermatology, Volume 25, Issue 9, September 2026.
ABSTRACT Background Stem cell‐based therapies have emerged as promising interventions for skin rejuvenation, yet a comprehensive synthesis of clinical evidence with systematic methodology is lacking. Previous reviews have been narrative in nature, limiting their utility for evidence‐based clinical decision‐making. Objective To systematically review and

Ultrasound Biomicroscopic Evaluation of Postoperative Anterior Segment Changes in Canine Intumescent Cataracts

Veterinary Ophthalmology, Volume 29, Issue 5, September 2026.
ABSTRACT Objective This study aimed to evaluate pre‐ and postoperative changes in the iridocorneal angle, ciliary cleft (CC), and ciliary muscle (CM) in canine eyes with intumescent cataracts using ultrasound biomicroscopy (UBM), with comparative reference to normal and non‐intumescent cataractous eyes.
