Lucid Dreaming Frequency Associated With Grey–White Matter Networks: An Exploratory Multimodal MRI Study

open access: yesJournal of Sleep Research, Volume 35, Issue 4, August 2026.
ABSTRACT Lucid dreaming, defined as the experience of becoming aware of dreaming while dreaming, offers a unique window into a state of consciousness characterised by a blending of the sensory vividness of REM sleep with the self‐awareness of wakefulness. While past functional imaging has shed light on the neural activity supporting lucid dreaming, the

Nonlinear Blind Source Separation for Sparse Sources

open access: yes, 2016
International audience—Blind Source Separation (BSS) is the problem of separating signals which are mixed through an unknown function from a number of observations, without any information about the mixing model.

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

Myeloid HDAC7 drives liver inflammation and systemic glucose dysregulation during diet‐induced obesity

open access: yesClinical &Translational Immunology, Volume 15, Issue 6, 2026.
This study explored the role of the class IIa histone deacetylase HDAC7 in hepatic inflammation and metabolic disease. Genetic approaches in mice revealed that myeloid HDAC7 drives hepatic inflammation and gene signatures associated with advanced chronic liver disease.

Data‐Driven Characterization of Knee Structures Using Non‐Negative Matrix Factorization of 3D Multi‐Echo UTE MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 6, June 2026.
Non‐negative matrix factorization (NMF) can derive tissue features in a data‐driven manner without relying on biophysical model assumptions. First‐time application of NMF to 3D multi‐echo UTE knee MRI revealed four reproducible components associated with tissues of fast and slow transverse relaxation, water–fat mixture (chemical shift), and fat tissue.

Pathological classification of Fuchs endothelial corneal dystrophy into several types and their relationships with CTG18.1 expansion repeats

open access: yesThe Journal of Pathology, Volume 269, Issue 2, Page 182-196, June 2026.
Abstract Late‐onset Fuchs endothelial corneal dystrophy (FECD) is the most common primary disease of the corneal endothelium and the leading indication for corneal transplantation in Western countries. It is characterized by progressive accumulation, over two to three decades, of extracellular matrix (ECM) components in Descemet's membrane (DM ...

A MLE-based blind signal separation method for time–frequency overlapped signal using neural network

open access: yesEURASIP Journal on Advances in Signal Processing, 2022
The blind signal separation (BSS) algorithm obtains each original/source signal from the observed signal collected by the receiving antenna or sensor. Objective/loss/cost function and optimization method are two key parts of BSS algorithm.

Effect of chilled eye drops on postoperative pain sensation after phototherapeutic keratectomy: Randomised controlled clinical trial

open access: yesActa Ophthalmologica, Volume 104, Issue 4, Page 438-447, June 2026.
Abstract Purpose To analyse pain sensation after phototherapeutic keratectomy (PTK) using chilled eye drops or drops at room temperature during the early postoperative period. Methods Our randomised controlled, parallel‐group study conducted in the Department of Ophthalmology, Goethe‐University, Frankfurt (Main), Germany, with blinded participants and ...
