Deep Representation-Based Feature Extraction and Recovering for Finger-Vein Verification

IEEE Transactions on Information Forensics and Security, 2017
Finger-vein biometrics has been extensively investigated for personal verification. Despite recent advances in finger-vein verification, current solutions completely depend on domain knowledge and still lack the robustness to extract finger-vein features

Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

Advanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species （ROS）generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

Using an age-dependent D-dimer cut-off value increases the number of older patients in whom deep vein thrombosis can be safely excluded

Haematologica, 2012
Background D-dimer testing to rule out deep vein thrombosis is less useful in older patients because of a lower specificity. An age-adjusted D-dimer cut-off value increased the proportion of older patients (>50 years) in whom pulmonary embolism could be ...

Engineered Peptides‐Based Hybrid‐Nested Microneedle Effectively Treat Biofilm‐Infected Diabetic Wounds

Advanced Functional Materials, EarlyView.
A hybrid‐nested microneedle/cryogel scaffold (MQW‐CMg‐MOF) is designed for efficient biofilm removal and accelerated healing of diabetic wounds. The scaffold shows substantial biofilm removal in vitro and in a preclinical diabetic swine biofilm‐infected wound model compared to the control.

Non-destructive three-dimensional measurement of hand vein based on self-supervised network [PDF]

arXiv, 2019
At present, supervised stereo methods based on deep neural network have achieved impressive results. However, in some scenarios, accurate three-dimensional labels are inaccessible for supervised training. In this paper, a self-supervised network is proposed for binocular disparity matching (SDMNet), which computes dense disparity maps from stereo image

Deep learning-driven pulmonary artery and vein segmentation reveals demography-associated vasculature anatomical differences [PDF]

Nat Commun 16, 2262 (2025)
Pulmonary artery-vein segmentation is crucial for disease diagnosis and surgical planning and is traditionally achieved by Computed Tomography Pulmonary Angiography (CTPA). However, concerns regarding adverse health effects from contrast agents used in CTPA have constrained its clinical utility.

Tissue factor expressed by circulating cancer cell‐derived microparticles drastically increases the incidence of deep vein thrombosis in mice

Journal of Thrombosis and Haemostasis, 2015
The risk of thrombotic complications such as deep vein thrombosis (DVT) during tumor development is well known. Tumors release into the circulation procoagulant microparticles (MPs) that can participate in thrombus formation following vessel injury.

Biodegradable, Humidity‐Insensitive Mask‐Integrated E‐Nose for Sustainable and Non‐Invasive Continuous Breath Analysis

Advanced Functional Materials, EarlyView.
This study introduces a paper‐based biodegradable, humidity‐insensitive e‐nose for real‐time breath analysis, addressing challenges in existing technologies such as humidity interference, high costs, and environmental impact. Featuring hydrophobic polymer coatings, these sensors reliably detect VOCs even in high‐moisture environments.

Deep Learning Techniques for Hand Vein Biometrics: A Comprehensive Review [PDF]

arXiv
Biometric authentication has garnered significant attention as a secure and efficient method of identity verification. Among the various modalities, hand vein biometrics, including finger vein, palm vein, and dorsal hand vein recognition, offer unique advantages due to their high accuracy, low susceptibility to forgery, and non-intrusiveness.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
