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

Journal of Sleep Research, EarlyView.
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

Adaptive Pilot Clustering in Heterogeneous Massive MIMO Networks

, 2016
We consider the uplink of a cellular massive MIMO network. Acquiring channel state information at the base stations (BSs) requires uplink pilot signaling.

How the Butler Did It: Investigating Individual City Influence on National Policy

Regulation &Governance, EarlyView.
ABSTRACT In most political systems, cities are not formally part of national policymaking. However, since they are often responsible for the implementation of national policies, they are likely to seek influence on these policies. Existing literature deals mostly with institutionalized policy cooperation and collective municipal organizations. As such,

Visibility Evaluation of Fundic Gland Polyp Associated With Proton Pump Inhibitor in Texture and Color Enhancement Imaging

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives A ‘gray color sign’ (GCS) is a new endoscopic feature of fundic gland polyp associated with proton pump inhibitor (PPI‐FGP). Here, we compare the ability of texture and color enhancement imaging (TXI) to white light imaging (WLI) with regard to the detection of GCS. Methods In this prospective study, 19 consecutive patients with PPI‐

Thermomechanical Analysis of Continuous Bamboo Strips Reinforced Vanillin‐Based Epoxy Resin Composites

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Thermomechanical properties of vanillin‐based epoxy resin/continuous bamboo strips composites. ABSTRACT The majority of thermosetting epoxy resins employed in organic composites are petroleum‐based and impacted by REACh regulation. However, research is undertaken to make epoxy resins greener.

Wireless Node Cooperation with Resource Availability Constraints

, 2017
Base station cooperation is a promising scheme to improve network performance for next generation cellular networks. Up to this point research has focused on station grouping criteria based solely on geographic proximity.

Machine Learning‐Enhanced Clinical Decision Support for Diagnosing Sinusitis With Nasal Endoscopy

International Forum of Allergy &Rhinology, Volume 16, Issue 2, Page 152-161, February 2026.
ABSTRACT Background Sinusitis is a prevalent disease for which nasal endoscopy (NE) is an optimal diagnostic modality. However, NE accuracy is limited by inter‐operator variability in landmark identification and localization of mucus that is necessary for sinusitis diagnosis. We sought to develop a novel multi‐class machine learning (ML) framework that

Joint Pilot Design and Uplink Power Allocation in Multi-Cell Massive MIMO Systems

, 2018
This paper considers pilot design to mitigate pilot contamination and provide good service for everyone in multi-cell Massive multiple input multiple output (MIMO) systems. Instead of modeling the pilot design as a combinatorial assignment problem, as in

Endomyocardial Fibrosis Associated With Hypereosinophilic Syndrome: Diagnostic and Management Insights From a Case Report

Catheterization and Cardiovascular Interventions, Volume 107, Issue 2, Page 520-523, February 1, 2026.
ABSTRACT Endomyocardial fibrosis (EMF) is a rare form of restrictive cardiomyopathy associated with eosinophilic disorders, characterized by apical subendocardial fibrosis and thrombus formation. Cardiac magnetic resonance (CMR) provides a comprehensive, noninvasive evaluation, enabling diagnosis, assessment of disease activity, and guidance of therapy.

Differential fast fixed-point algorithms for underdetermined instantaneous and convolutive partial blind source separation

, 2007
This paper concerns underdetermined linear instantaneous and convolutive blind source separation (BSS), i.e., the case when the number of observed mixed signals is lower than the number of sources.We propose partial BSS methods, which separate supposedly
