A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

Advanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

Mechanical Behavior of a Partially Encased Composite Girder with Corrugated Steel Web: Interaction of Shear and Bending

Engineering, 2017
The synergistic use of partially encased concrete and composite girders with corrugated steel webs (CGCSWs) has been proposed to avoid the buckling of corrugated steel webs and compression steel flanges under large combined shear force and bending moment

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping

Advanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Noise-resilient designs and analysis for optical neural networks

Neuromorphic Computing and Engineering
All analog signal processing is fundamentally subject to noise, and this is also the case in next generation implementations of optical neural networks (ONNs). Therefore, we propose the first hardware-based approach to mitigate noise in ONNs. A tree-like

Studying Some Important Aspects of Corrugated Steel Web in Girders

Misan Journal of Engineering Sciences
As a result of the high advantages of corrugated steel webs, their use has advanced over the conventional plate in recent times. The corrugated web girder has a distinctive geometrical form that enhances the shear buckling behavior of the girder.

Design and Characterization of a Dual‐Mode Soft Robotic Flapping Propeller With Pneumatic Stiffness Modulation

Advanced Intelligent Systems, EarlyView.
A novel soft robotic propeller overcomes traditional efficiency‐flexibility tradeoffs via a hybrid pneumatic‐cable actuation strategy. This architecture enables active stiffness modulation with dual‐mode locomotion: tunable biomimetic swimming and earthworm‐inspired wriggling for confined spaces.

The role of editorial boards in shaping scholarly communication: A large‐scale mapping of their composition and structure

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Editorial boards play a central role in shaping scholarly communication by influencing what research is published and how disciplinary boundaries are defined. Despite their importance, large‐scale, systematic evidence on their composition and structure remains limited.

Two novel human cytomegalovirus NK cell evasion functions target MICA for lysosomal degradation.

PLoS Pathogens, 2014
NKG2D plays a major role in controlling immune responses through the regulation of natural killer (NK) cells, αβ and γδ T-cell function. This activating receptor recognizes eight distinct ligands (the MHC Class I polypeptide-related sequences (MIC) A ...

Accordion Effect During Percutaneous Coronary Intervention (Pci)

, 2023
Pseudo lesions appear in a coronary artery during intervention due to guide wire manipulation are referred as “accordion phenomenon” and are infrequent occurrences during percutaneous coronary intervention of tortuous coronary arteries. Occurrence of pseudo lesion or accordion phenomena puts a diagnostic challenge to the interventionist and might leads
