Single-Channel Blind Image Separation Based on Transformer-Guided GAN

Sensors, 2023
Blind source separation (BSS) has been a great challenge in the field of signal processing due to the unknown distribution of the source signal and the mixing matrix.

Combining Superdirective Beamforming and Frequency-Domain Blind Source Separation for Highly Reverberant Signals

EURASIP Journal on Audio, Speech, and Music Processing, 2010
Frequency-domain blind source separation (BSS) performs poorly in high reverberation because the independence assumption collapses at each frequency bins when the number of bins increases.

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.

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

Radar main‐lobe jamming suppression and identification based on robust whitening Blind Source Separation and Convolutional Neural Networks

IET Radar, Sonar & Navigation, 2022
The main‐lobe jamming causes serious degradation of radar system performance in practical applications. In recent years, the Blind Source Separation (BSS) method has been applied to suppress the main‐lobe jamming.

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 ...

Variable learning rate EASI-based adaptive blind source separation in situation of nonstationary source and linear time-varying systems [PDF]

, 2019
In the case of multiple nonstationary independent source signals and linear instantaneous time-varying mixing systems, it is difficult to adaptively separate the multiple source signals.

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
