Discrimination-Aware Integration for Person Re-Identification in Camera Networks

open access: yesIEEE Access, 2019
In this paper, we propose a novel method named Discrimination-Aware Integration (DAI) for person re-identification (re-ID) in camera networks, which not only integrates multiple re-ID models but also adaptively learns integration weights for different ...

A Novel Relay Node Placement and Energy Efficient Routing Method for Heterogeneous Wireless Sensor Networks

open access: yesIEEE Access, 2020
In heterogeneous wireless sensor networks (HWSN), sensor nodes may fail due to running out of battery power or sudden damage. This causes HWSN being partitioned to a number of separate networks.

A hierarchically sampling global sparse transformer in data stream mining for lightweight image restoration

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
With the rapid development of information technology, mining valuable information from multi-source data stream is essential for redundant data, particularly in image processing; the image is degraded when the image sensor acquires information. Recently,

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Integration graph attention network and multi‐centre constrained loss for cross‐modality person re‐identification

open access: yesIET Computer Vision, 2023
Cross‐modality person re‐identification is a challenging task due to the large visual appearance difference between RGB and infrared images. Existing studies mainly focus on learning local features and ignore the correlation between local features.

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

In Vivo Monitoring of Thrombo‐Inflammatory Biomarkers via Molecularly Imprinted Polymer‐Integrated Hydrogel Microneedles

open access: yesAdvanced Materials, EarlyView.
A wearable electrochemical microneedle patch integrates Prussian Blue redox transduction with molecularly imprinted polymer recognition for reagent‐free sampling and detection of thrombo‐inflammatory biomarkers in dermal interstitial fluid. The platform tracks thrombin and inflammatory cytokines with sensitive in vitro, ex vivo, and in vivo performance,

Correntropy-based DOA estimation algorithm under impulsive noise environments

open access: yesEURASIP Journal on Wireless Communications and Networking, 2020
In this paper, the direction of arrival (DOA) estimation of signals in the presence of impulsive noise environment is studied. Complex isotropic symmetric alpha-stable (SαS) random variables are modeled as impulsive noise, then a novel second-order ...
