Design and Experimental Validation of a Biomimetic Jellyfish Robot with Asymmetric-Stiffness Swimming Arms and Dual-Power Cooperative Drive

This study presents a biomimetic jellyfish robot integrating asymmetric-stiffness swimming arms with motor–spring cooperative actuation. Motor-driven spring charging and rapid spring release organize the recovery, power-stroke, and gliding phases. Hinged arm segments, return micr...

Cardiac signal monitoring using femtosecond laser inscribed FBGs in CYTOP optical fiber

In this study, fiber Bragg gratings (FBGs) were inscribed into cyclic transparent optical polymer (CYTOP) optical fibers using a femtosecond laser plane-by-plane (Pl-b-Pl) technique. A custom-designed integrated cardiac sensor was then developed, incorporating a 3D-printed struct...

GLAM-YOLO: a global-local attention and multi-scale fusion enhanced YOLOv10 framework for robust SAR object detection

Synthetic aperture radar (SAR), with its all-weather and all-day imaging capability, has become indispensable in military reconnaissance and remote sensing applications. However, SAR object detection remains challenging due to strong speckle noise, the frequent presence of small-...

From pollution control to system governance: five decades of environmental policy evolution in China

China's environmental governance has undergone a profound transformation since the late 1970s, with implications that extend far beyond its borders. Existing accounts of this evolution rely largely on qualitative periodisation and expert interpretation, offering limited capacity...

Agarose-Encapsulated Multifunctional Microspheres with High Drug Payload and Multimodal Imaging Capability for Arterial Embolization–Associated Hyperthermia Therapy

Hepatocellular carcinoma (HCC) represents a leading cause of cancer-related mortality worldwide, and transarterial chemoembolization (TACE) remains the standard first-line locoregional therapy for intermediate-stage HCC. Nevertheless, conventional TACE frequently yields suboptima...

Tailoring the thermal conductivity of boron nitride-based materials through microstructural and architectural design for thermal management applications

The escalating power density of modern electronics has intensified the demand for thermal interface materials (TIMs) that simultaneously deliver high thermal conductivity and reliable electrical insulation. Hexagonal boron nitride (h-BN) has emerged as a leading filler candidate;...

Formation mechanism of the digital literacy divide among farmers: a qualitative study from China

Based on in-depth interviews with 30 Chinese farmers, this paper adopts a qualitative research approach to explore the formation mechanism of the digital literacy divide among farmers. Findings indicate that personal characteristics, external conditions, and digitalization willin...

Updating thermal head of RECoverable Autonomous Sonde (RECAS) for better drilling performance in Qilin Subglacial Lake exploration

Abstract. There are numerous subglacial lakes in Antarctica, typically covered by thick ice sheets. Qilin subglacial lake is one of the largest subglacial lakes in Antarctica, lying beneath approximately 3600 m of ice. The exploration of this unique environment is of considerable...

Study on friction characteristics at the rolling interface under vertical-horizontal coupled vibration of rolling mill systems based on dynamic rolling force

This study addresses the limitations of conventional steady-state rolling models in characterizing metal flow dynamics and force-energy parameters at the rolling interface under vertical-horizontal coupled roll vibrations. Based on the principle of mass conservation, a three-dime...

Holistic foreground–background guided feature learning for few-shot strip steel defect segmentation

Strip steel surface defect (S 3 D) segmentation has become an indispensable technique for surface inspection in strip steel production lines. However, the imbalance between the foreground and background, as well as the complex defect appearances, have become the main challenges i...

Attention-Guided Efficient Structure Reassembly Through Reverse Contribution-Driven Feature Distillation and Inconsistency-Resilient Sample Filtering

Excessive features and/or inconsistent samples in practical complex system modeling often misguide decision-makers’ attention. To address this challenge, a novel attention-guided efficient structure reassembly approach is proposed through reverse contribution-driven feature disti...

A generalizable biopsychosocial risk score for stratifying disease vulnerability in healthy populations

Prospective risk stratification of future adverse health outcomes before clinical onset among ostensibly healthy individuals is an important goal of preventive and precision medicine, yet current tools remain largely disease-specific and do not provide an integrated measure of he...

Noncatalytic Synthesis of High‐Density and Small‐Diameter WS 2 Nanotubes

ABSTRACT A substrate‐engineered, noncatalytic strategy is developed for the controlled synthesis of high‐density WS 2 nanotubes by decoupling nanowire precursor growth from vapor‐phase sulfuration. The process enables precise structural control and yields dense nanotube networks...

Bio-based multifunctional coatings for cotton fabrics: integrating flame retardancy, antibacterial and hydrophobic properties

Abstract Cotton fabrics offer excellent comfort and biodegradability, but suffer from high flammability and poor antibacterial properties, limiting their use in safety–critical applications. Herein, a multifunctional modification strategy is proposed: phosphonated hyaluronic acid...

Dynamic patch bank with a defect filter for cold start in online engineering inspection

In industrial defect detection, real-world complexities such as cold starts, pervasive label noise, and newly emerging defect classes pose significant challenges to traditional approaches. We propose a Dynamic Patch Bank with a Defect Filter, a unified artificial intelligence bas...

Salient Object Detection in Complex Weather Conditions via Noise Indicators

ABSTRACT Salient object detection (SOD), a foundational task in computer vision, has advanced from single‐modal to multi‐modal paradigms to enhance generalisation. However, most existing SOD methods assume low‐noise visual conditions, overlooking the degradation of segmentation a...

Decoupling Electron and Hole Injection Dynamics in Colloidal Nanocrystals via Potentiostatic Polarization Spectroelectrochemistry

Abstract The outstanding optoelectronic potential of colloidal nanocrystals has driven intensive study of their charge carrier behavior. However, conventional spectroelectrochemistry (SEC) may yield results that deviate from practical device operation because it typically relies...

A note on blow-up criterion of solutions to a Fornberg-Whitham-type equation

In this note, we revisit blow-up phenomena of solutions to a Fornberg-Whitham-type equation, which models shallow-water wave dynamics. We derive a blow-up criterion for the initial data by means of a subtle analysis of a coupled Riccati-type inequality system involving the soluti...

TRACE-FND: A Constrained Evidence-Agent Workflow with Trainable Graph Adjudication for Multimodal Fake-News Detection

Multimodal misinformation often preserves individually plausible text and images while manipulating their relation, provenance, timing, or omitted context. Existing detectors mainly learn fused correlations or verify normalized claims, leaving temporal validity, source reliabilit...
