Multi-label arrhythmia classification from Holter scatter plots using deep learning and clinically oriented thresholds

Abstract Automated analysis of long-term Holter recordings is important for efficient arrhythmia screening, but most deep learning approaches rely on raw electrocardiographic waveforms. Heart-rate scatter plots provide a compact visual representation of rhythm dynamics and may su...

Therapeutic Properties and Underlying Mechanisms of Traditional Chinese Medicine in Managing Rheumatoid Arthritis: An Integrative Review of Clinical and Molecular Findings

Traditional Chinese medicine (TCM) has a long-standing history in the treatment of rheumatoid arthritis (RA), known as "Bi Zheng," and offers a comprehensive therapeutic approach characterized by multi-target and multi-pathway mechanisms. Modern pharmacological research has demon...

Enhancing MicroplasticRaman Spectral Quality andClassification via a Dual Encoder Residual Network

Abstract When addressing noise interference and baseline drift during the rapid Raman spectral analysis of microplastics, traditional denoising and baseline correction algorithms frequently exhibit limitations such as parameter sensitivity, reliance on manual intervention, and in...

Manipulation of Photoresponse via Defect-Level Excitations in Metal–Insulator–Semiconductor-Type Two-Dimensional Heterostructure for Optoelectronic Logic Gates

Abstract In recent years, effective carrier–exciton conversion and defect engineering in tunneling diodes based on metal–insulator–semiconductor (MIS) van der Waals heterostructures have attracted extensive research interest in modulating optoelectronic device performance. Effect...

Single Particle All‐Optical Synapses

ABSTRACT Artificial synapses for emulating the synaptic behaviors and neuromorphic computing have been extensively exploited based on the temporal response of diverse physical and chemical processes. In these synaptic devices, operating in an all‐optical fashion offers significan...

Freq-LoRA: Frequency-Domain Low-Rank Adaptation for Weather-Robust Aircraft Segmentation in EO Remote Sensing

Adverse weather poses a major challenge to ground-based electro-optical (EO) aircraft surveillance. Existing parameter-efficient fine-tuning (PEFT) methods operate mainly in the spatial domain and treat weather as a generic domain shift rather than a frequency-dependent degradati...

Co–Cu Bimetallic ZIF-67@PDA-Based Fabrics: Trimodal Synergistic Antibacterial Performance for Reusable Protective Textiles

Abstract Protective textiles are essential for public health security, yet conventional textiles only physically filter microorganisms without rapid surface sterilization, easily becoming potential cross-infection sources. Commercial antibacterial variants also suffer from slow s...

Ferromagnetic Coupling in Dual‐Atom Nanozymes Enables Spin‐Favorable Catalase‐Like Catalysis for Rheumatoid Arthritis Therapy

ABSTRACT Iron dual‐atom (Fe DA) nanozymes, structurally analogous to natural catalase, exhibit promising catalase‐like (CAT‐like) activity, yet further improving their catalytic performance and elucidating the underlying mechanism remain major challenges. Herein, we developed a c...

Research on an Absolute Radiometric Calibration Method Based on a Point Source Array

Factors such as the optical point spread function (PSF), intrapixel sensitivity (IPS), and interpixel crosstalk of an imaging system can cause the response to point sources to vary with position, directly affecting the absolute radiometric calibration accuracy of the remote senso...

High‐Efficiency and Carbon‐Lean Electrochemical Desalination Enabled by Nucleophilic Engineering of Organic Molecular Electrode

ABSTRACT The worsening global freshwater crisis positions seawater desalination as a critical solution. However, conventional desalination technologies remain constrained by a persistent sustainability trilemma involving high energy consumption, chemical reliance, and substantial...

CFD-Based Simulation and Optimization of Summer Environmental Conditions in Laying Hen Houses

To address uneven temperature and relative humidity distributions, localized heat accumulation, and insufficient air velocity in an enclosed stacked-cage laying hen house, a three-dimensional computational fluid dynamics (CFD) model of the laying hen house was developed using fie...

Tribological Behavior and Attachment Force Regulation of Bioinspired Claw–Spines

This study investigates the tribological behavior of the attachment force between bio-inspired claw–spines and rough surfaces and conducts theoretical and model-based analyses of the corresponding attachment mechanism. Based on critical interfacial tribological theory, a friction...

Lithium Acetylacetonate Mediated Multidimensional Optimization for Reversible Zn Anodes

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) are promising for large‐scale energy storage owing to their high safety, yet their practical application is hindered by uncontrollable zinc dendrite growth, interfacial side reactions, and poor deposition reversibility of zinc anodes. H...

CIP2A–TOPBP1 complex and PP2A dynamically regulate Polθ recruitment and phosphorylation at mitotic DNA double-strand breaks

DNA double-strand breaks (DSBs) that occur during mitosis are primarily repaired by Polθ-mediated microhomology-mediated end joining (MMEJ). The CIP2A–TOPBP1 complex has been shown to tether broken chromatin at mitotic DSBs, but whether it coordinates with or functions independen...
