Integrated Mobile Visible Light Communication and Positioning Systems Based on Decision Feedback Channel Estimation

Photonics
Visible light communication (VLC) and visible light positioning (VLP) systems are usually designed separately to prevent mutual interference, while terminal mobility often introduces challenges that can degrade their performance.

The Integration of Photodiode and Camera for Visible Light Positioning by Using Fixed-Lag Ensemble Kalman Smoother

Remote Sensing, 2019
Visible Light Positioning (VLP) has become one of the most popular positioning and navigation systems in this decade. Filter-based VLP systems can provide real-time solutions but have limited accuracy.

Deep Mutational Scanning for the Study and Engineering of Protein Assemblies

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review explores how deep mutational scanning (DMS) can be used to improve understanding and accelerate engineering of protein assemblies, from natural fibers to engineered nanocages. We discuss various types of protein assemblies and their characterization, provide an introduction to the DMS technique, and then highlight examples in which DMS has ...

Viral Infection‐Inspired Autonomous Detection of Fusion‐Competent Viruses for Screening and Environmental Surveillance

Advanced Materials, Volume 38, Issue 40, 17 July 2026.
Inspired by viral entry mechanisms, the FUSION assay enables autonomous detection of respiratory viruses via membrane fusion–triggered CRISPR‐Cas13a activation. VEACON selectively fuses with fusion‐competent viruses, triggering fluorescence within confined vesicles.

Changes in body composition in genetic C9orf72 carriers: The role of the hypothalamus and thalamus

Alzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract BACKGROUND Patients with sporadic frontotemporal dementia (FTD) display changes in metabolism and body composition. No studies have examined body composition changes in pre‐symptomatic C9orf72 mutation carriers METHODS Asymptomatic C9orf72 expansion carriers between 2017 and 2022 (n = 28 non‐carriers, 16 expansion‐positive), underwent dual ...

High-Speed Robust Dynamic Positioning and Tracking Method Based on Visual Visible Light Communication Using Optical Flow Detection and Bayesian Forecast

IEEE Photonics Journal, 2018
There are three critical elements in visible light positioning (VLP) system: Positioning accuracy, real-time ability, and robustness. However, most of the existing VLP studies only focus on the positioning accuracy and only a few studies consider the ...

Oxidation of Manganese(II) With Ferrate Revisited: The Overlooked Role of Hardness Cations

AWWA Water Science, Volume 8, Issue 4, July/August 2026.
ABSTRACT Manganese (Mn) is a concern for some groundwater‐sourced drinking water systems. Ferrate (Fe(VI)) is a promising alternative oxidant for Mn treatment, but particle formation during Mn(II) oxidation is not well understood under realistic groundwater conditions with high hardness (> 180 mg/L) and low natural organic matter (< 1 mg/L NOM).
