Sequence Labeling in Urdu Social Media Texts: Data Annotation and Transformer-Based Deep Learning Models

Sequence labeling tasks such as part-of-speech (POS) tagging and named entity recognition (NER) have advanced significantly in high-resource languages and well-structured texts. However, low-resource languages, such as Urdu, face unique challenges due to limited annotated resourc...

Seasonaland Habitat-Specific Mercury Cycling in CoastalBiota Revealed by Species-Specific Isotopes

Abstract Understanding how inorganic mercury (IHg, primarily Hg(II)) and methylmercury (MeHg, primarily monomethylmercury) transform and cycle in coastal food webs is essential for evaluating Hg exposure risks, yet relevant species-specific mercury (Hg) isotope studies remain sca...

Urban Resilience Capacity Assessment and Key Factor Contribution Analysis in the Northern Slope of Tianshan Mountains Urban Agglomeration: Based on the XGBoost Model

Addressing the issue of ecological vulnerability and against the backdrop of urban expansion in arid regions, this study constructs a composite urban resilience capacity index (CURCI) for the urban agglomeration on the northern slopes of the Tianshan Mountains and examines its sp...

Evolution of the Mechanical Properties of Recycled Glass Fibers During Pyrolysis–Oxidation of Waste Wind Turbine Blades

ABSTRACT Pyrolysis is a promising route for recycling decommissioned wind turbine blades, but resin‐derived residues and thermal exposure can damage recovered glass fibers. This study investigated the surface morphology, fracture characteristics, and mechanical‐property evolution...

Runoff Simulation and Analysis in the Upper Yellow River Basin Using a Budyko–XGBoost Coupled Model

The Upper Yellow River (UYR) basin is the predominant runoff-yielding area of the entire watershed. Accurately simulating annual runoff is crucial for water resources management. While the Budyko framework effectively captures long-term hydro-thermal equilibrium, it struggles to...

A Universal Fenton‐Like Strategy for Selective Generation of 1 O 2 in Mixed Industrial Wastewater Treatment and Green Chemical Synthesis

ABSTRACT Sustained and selective generation of singlet oxygen ( 1 O 2 ) in Fenton‐like catalytic systems is highly desirable for diverse applications, from freshwater resource management to green chemical synthesis. Despite advances in advanced oxidation processes, there remains...

External‐Field‐Enhanced Helmholtz‐Layer Local Charge Density Enables C─C Coupling in Pure‐H 2 O‐Fed CO 2 Electroreduction To C 2+ Products

ABSTRACT Electrochemical CO 2 reduction (ECO 2 R) is a promising decarbonization technology but is limited by the trade‐off between catalytic performance and system stability. Here, we present an external‐field‐assisted strategy to enhance the local charge density of the Helmholt...

The Shape-SelectiveSuspension–Deposition Differentiationof Microplastics in an Air–Snow System: Insights from a NortheasternPolluted City in China

Abstract Atmospheric microplastics (MPs) are increasingly recognized as important atmospheric pollutants, yet the role of particle physical properties in their suspension–deposition differentiation remains unclear. Here, MPs were simultaneously investigated in 31 total-suspended-...

Kinetic-Controlled Dissolution-Diffusion-Recrystallization of Hollow Two-Dimensional Conductive Metal-Organic Frameworks@MXene Heterojunctions for High-Performance Lithium Storage

Abstract Two-dimensional conductive metal-organic frameworks (2D c-MOFs) hold great promise as anodes for next-generation high-energy density devices, yet their practical application is hindered by insufficient exposure of the active site caused by layer stacking and limited spec...

Effects of different storage conditions on the carbon isotopic compositions of dissolved inorganic carbon

Abstract The carbon isotopic compositions (δ 13 C and Δ 14 C) of dissolved inorganic carbon (DIC) in water samples are influenced by various storage conditions, but the extent and mechanisms of these changes remain unclear. In this study, we systematically evaluated the effects o...

Thermally Modulated Microfluidic Fabrication of Phase-Tunable Cs4PbBr6/CsPbBr3 Hybrid Perovskite Nanocrystals for White Light-Emitting Diodes

All inorganic CsPbBr3 perovskite nanocrystals (NCs) exhibit outstanding luminescence for optoelectronics, yet poor environmental stability severely restricts their practical deployment. As a stable derivative phase, Cs4PbBr6 can effectively improve structural stability. Neverthel...

Spatiotemporal-switchable 2D NIR-II single-atom nanozyme for single-cell–level surgical navigation and glioblastoma phototherapy

Single-cell–level resolution tumor therapy represents an advanced strategy against glioblastoma but lacks suitable theranostic agents. Here, we developed a spatiotemporal-switchable, two-dimensional (2D), bismuthene-based second near-infrared window (NIR-II) nanozyme. In this pla...

Exosomes in brain diseases: Mechanisms, advances, and perspectives

The blood–brain barrier (BBB) remains a major biological obstacle limiting the effective delivery of therapeutics for central nervous system (CNS) disorders. Although conventional drug delivery approaches have achieved continuous advances, their clinical translation is frequently...

Gill histological, biochemical and transcriptomic responses of Coregonus ussuriensis to acute salinity stress

Salinity is a key environmental factor affecting the osmoregulation and physiological homeostasis in freshwater fish. Juvenile Coregonus ussuriensis has been considered a candidate species for culture in moderately saline waters, but its short-term physiological and molecular res...

An Optimized CatBoost Model for Spatiotemporal Prediction of hmF2 in High-Latitude Regions
