From isolated foci to coordinated attending: Critical events identified by novice mathematics teacher-educators

This study examines how novice mathematics teacher educators' (NMTEs) attending changes over time, as reflected in the Critical Events in Teacher Education sessions (CETEs) they identify following teacher education sessions they facilitate. The study involved 45 in-service mathem...

Concentration of injury and fatality harm at repeat-active highway–rail grade crossings: A multi-state permutation and machine learning analysis

Highway–rail grade crossing incidents remain a transportation safety concern, yet prior studies have focused mainly on crash occurrence, severity, and hotspot detection, leaving limited evidence on how injury-or-fatality harm concentrates at crossings with repeated incidents. Usi...

Design and Flight Test of Kalman Filter and CNN Vision-based UAM Precision Landing System in GNSS-denied Environments

Urban air mobility (UAM) requires safe, precise takeoffs and landings at vertiports and helipads. However, in urban environments, global navigation satellite system (GNSS)-based positioning accuracy can be degraded by signal blockage and multipath propagation, reducing landing pr...

Health Policy for Obesity and Metabolic Syndrome in Asian Health Systems: Three Design Principles, Three Binding Constraints, and the Governance That Decides between Them

Background: Obesity drives metabolic syndrome and cardiometabolic disease in Asia, where complications develop at lower levels of adiposity than in Western populations. We reviewed Asian obesity policies to identify design features that support their durability and how access to...

A second chance? Outcomes of immunotherapy retreatment after prior checkpoint inhibitor exposure in endometrial and cervical cancer

OBJECTIVE(S): As immunotherapy (IO) is increasingly utilized for treatment of endometrial cancer (EC) and cervical cancer (CC), optimal treatment strategies after IO remains poorly defined. We evaluated clinical outcomes, treatment patterns, toxicity, and survival among patients...

Simulation Environment Generation Using a Persona-aware LLM

Collecting diverse real-world data for AI model training is often costly, time-consuming, and constrained by safety and experimental conditions, making simulation environments an important alternative for data collection. However, existing methods for generating simulation enviro...

Molecular-scale origins of shear-thinning in SiO₂-Al₂O₃-CaONa₂O slag: High-temperature rheology and non-equilibrium molecular dynamics

SiO₂-Al₂O₃-CaO Na₂O slag represent the basic constituents of high-alkali coal ash, and its non‑Newtonian rheology critically affects ash deposition and transport. In this study, their shear‑thinning behavior was investigated by combining high‑temperature rheometry (0–500 s⁻¹) wit...

GaN nanorods/N–doped carbon derived from Ga–MIL–68 as a separator coating for suppressing the shuttle effect in lithium–sulfur batteries

Lithium–sulfur batteries (LSBs) offer high theoretical energy density, yet their practical deployment is constrained by lithium polysulfide (LiPS) shuttling, sluggish sulfur redox kinetics, and unstable lithium deposition. This work addresses whether a single separator coating ca...

Effective number of communities reveals extent of biodiversity change – a cross-organism analysis in the Wadden Sea

Biodiversity changes in ecosystems worldwide, but assessing the true magnitude of this transformation requires the analysis of multiple dimensions of compositional change. Trends in α-diversity only capture the net difference between gains and losses, while year-on-year temporal...

TMT attention to technological innovation and AI invention: Evidence from Chinese listed firms

Artificial intelligence (AI) has become a central field of corporate innovation, yet firms differ substantially in the extent to which they develop AI inventions. Drawing on upper echelons theory and the attention-based view, this study examines whether top management team (TMT)...

From acquisition to recycling: Vegetation restoration reshapes microbial nitrogen-cycling strategies in a semi-arid sandy land

Reestablishing nitrogen (N) cycling is critical for stabilizing ecosystems in semi-arid sandy lands, yet the microbial mechanisms driving functional reorganization during vegetation restoration remain unclear. This study investigated the coupling of soil physicochemical propertie...

Mechanistic investigation of the bond-slip behavior of brick-mortar interfaces: From mortar decay to interfacial deterioration under sulfate attack

The bond-slip behavior at the brick-mortar interface plays a pivotal role in the long-term structural integrity of ancient masonry pagodas. Sticky rice paper pulp mortar (SRPPM), a key traditional material, is susceptible to environmental erosion. However, the quantitative link b...

Valorization of poultry waste into calcium salt of fatty acids (bypass fat): Characterization and techno-economic assessment

Global poultry production generates millions of tons of chicken fat and eggshell waste annually, posing significant solid waste management challenges. To address the environmental burden and underutilization of poultry processing waste, this study integrated waste valorization ap...

Mode transition and critical spatial aspect ratio of propane-air deflagration in long confined spaces

Propane-air deflagration in long confined spaces depends on both the initial combustible-cloud extent and the enclosure geometry. However, the combined influence of these two factors on deflagration mode transition remains unclear. In this study, a three-dimensional CFD model was...

Coupled effects of fuel corrosion and photothermal aging on asphalt binder degradation for airport pavements

Airport pavements face combined threats from photothermal aging and aviation fuel spillage, yet their synergistic degradation mechanisms are not fully elucidated. This study evaluates asphalt binder performance under coupled damage, revealing a distinct two-stage degradation patt...

Pneumococcal carriage and selected respiratory virus in children with clinical pneumonia in Salvador, Brazil during PCV10 era

Background In 2010, Brazil introduced the 10-valent pneumococcal conjugate vaccine (PCV10 GSK ). Assessing pneumococcal carriage among children with clinical pneumonia in the context of a mature PCV10 GSK program can inform decisions about use of next-generation PCVs. Methods We...

Synergistic co-intercalation of binary and ternary transition-metal cations in hydrated vanadium oxide nanosheets for high-performance aqueous zinc-ion batteries

Vanadium-based oxides have emerged as promising cathode materials in aqueous zinc-ion batteries (AZIBs), owing to their tunable layered architectures and high theoretical specific capacities. To date, hydrothermal/solvothermal synthesis remains the predominant approach for prepar...
