Nanomaterials for Allergy Diagnosis and Treatment: Advances, Opportunities and Translational Challenges

Advanced Science, EarlyView.
Nanomaterials offer dual applications in allergy management. For diagnosis, nanomaterials enhance analytical sensitivity and improve detection in specific IgE and functional assays such as the basophil activation test (BAT). For allergen‐specific immunotherapy, nanomaterials enable allergen masking and controlled release, and effectively modulate the ...

Visual-Inertial Fusion Based Positioning Systems

IEEE Access, 2020
In this paper, we developed a visible light positioning (VLP) system using a camera and low-cost inertial measurement units (IMUs). Applying computer vision and sensor fusion techniques, our VLP system is able to estimate the angle of arrival (AoA) and ...

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

Journal of Field Robotics, EarlyView.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Polarization-Based Visible Light Positioning

, 2019
Visible Light Positioning (VLP) provides a promising means to achieve indoor localization with sub-meter accuracy. We observe that the Visible Light Communication (VLC) methods in existing VLP systems rely on intensity-based modulation, and thus they ...

Vehicular Visible Light Positioning Using Receiver Diversity with Machine Learning [PDF]

, 2021
This paper proposes a 2-D vehicular visible light positioning (VLP) system using existing streetlights and diversity receivers. Due to the linear arrangement of streetlights, traditional positioning techniques based on triangulation or similar algorithms

Experimental demonstration of an indoor visible light positioning system using RGB LEDs for multi‐cell networks

The Journal of Engineering
A visible light positioning (VLP) system for multi‐cell networks based on multi‐colour LED that combines frequency division multiplexing with the received signal strength and a trilateration method is proposed. First, it employs experimental measurements

Peptide‐Ligand Cooperative Interplay Drives Gold Nanoparticle Encapsulation by Protein Cages

Small, EarlyView.
Gold nanoparticle encapsulation within protein cages is governed by salt‐dependent binding energetics and cooperative peptide–ligand interactions. Ligands enhance electrostatic attraction while peptides extend recruitment and prevent kinetic trapping, enabling robust cargo loading. This molecular‐level insight links experiments and simulations, guiding
