Shifting cognitive structures in human-AI collaborative learning design

This study examines collaborative learning design with a generative artificial intelligence (GenAI) co-pilot among in-service university English teachers in China. In a between-subjects experiment ( N = 60), epistemic network analysis (ENA) was used to model the situated discours...

Modeling of vibrational non-equilibrium in detonation with global kinetics

One-, two-, and three-step global kinetic models that include thermal non-equilibrium were developed for detonation simulations using the open-source software Cantera and the Shock and Detonation Toolbox (SDToolbox). The rate coefficients and thermodynamic parameters of these mod...

Proteomics insight into phosphate limitation response in Burkholderia phytopathogens

Inorganic phosphate (Pi) limitation is a pervasive environmental constraint that shapes microbial behaviour in soil and plant-associated niches. To determine how Pi scarcity influences the pathogenic potential of rice-infecting Burkholderia species, we performed comparative prote...

Interpolating chromatic and homomorphism thresholds

The problem of chromatic thresholds seeks minimum degree conditions that ensure that dense H -free graphs have a bounded chromatic number, or equivalently a bounded size homomorphic image. The strengthened homomorphism thresholds problem further requires that the homomorphic imag...

A pair of chitosan receptors confer broad-spectrum fungal resistance

Chitosan, a major fungal cell wall component, activates plant immunity, yet the underlying perception mechanism remains unknown. In this study, we identified OsFID1, an apoplast-localized DUF26 domain protein, as a chitosan-binding receptor essential for chitosan-triggered immuni...

Laser-induced phosphorescence thermometry for dynamic temperature measurement of a film-cooled aero-engine model combustor liner at elevated pressure

Accurate knowledge of aero-engine combustor liner temperature fields is essential for cooling design, combustion evaluation, thermal-risk assessment, and life prediction. Although laser-induced phosphorescence (LIP) thermometry enables non-contact, spatially resolved surface ther...

Enzymatic cross-linking collagen-based bioink for 3D bioprinting of endometrial model with endometrial epithelial organoids

The human endometrium, a dynamic tissue responsive to sex hormones, plays a pivotal role in female reproduction and menstrual cycling, comprising diverse cell populations including epithelial and stromal cells. The development of in vitro endometrial models holds substantial pote...

Dual cascade of two-dimensional turbulence arising from collective swimming

Abstract Using high-resolution numerical simulations, supported by shallow-water tank experiments, we show that the collective swimming of fish at finite Reynolds numbers can spontaneously generate two-dimensional (2D) turbulence. The resulting flow exhibits a robust dual-cascade...

Reduced-Order Modeling of Hamiltonian Dynamics Based on Symplectic Neural Networks

Abstract. We introduce a novel data-driven symplectic reduced-order modeling (ROM) framework for high-dimensional Hamiltonian systems that unifies latent-space discovery and dynamics learning within a single, end-to-end neural architecture. The encoder–decoder is built from Hénon...

Unified Physics-Guided Discovery of Ultrahigh- and Ultralow-Thermal Conductivity Two-Dimensional Materials

Abstract As thermal management approaches the low-dimensional limit in post-Moore electronics, two-dimensional (2D) materials offer a versatile platform for engineering lattice thermal conductivity (κL). However, a unified framework capable of discovering both ultrahigh- and ultr...

Thermodynamic characteristics and structural optimization of pure hydrogen vortex tubes: An experimental and numerical investigation

Efficient thermal management of high-pressure hydrogen (H 2 ) is a critical bottleneck in the global hydrogen energy infrastructure. The Ranque-Hilsch Vortex Tube (RHVT), possessing intrinsic safety with zero moving parts, presents an ideal cooling solution for explosive H 2 envi...

This paper presents a photo-realistic LiDAR-Inertial-Camera Gaussian Splatting SLAM system that simultaneously addresses visual quality, geometric accuracy, and real-time performance. The proposed method performs robust and accurate pose estimation within a continuous-time trajec...

Extract from Eucommia ulmoides Oliv. Leaves alleviates APAP-induced acute liver injury via reshaping gut microbiota and attenuating microbial bile acids metabolism disorder

Abstract Background Increasing studies suggest that supplementing flavonoids from Eucommia ulmoides Oliv. Leaves (EUL) exerts liver protective effects via reshaping gut microbiota and regulating bile acids (BAs) metabolism. However, the relationship between EUL, gut microbiota an...

Quantifying Geographic Domain Shift to Decouple the Geospatial Transferability of Human Mobility Flow Generations

Human mobility serves as an essential proxy for understanding social, economic, and environmental dynamics in urban systems. However, since human mobility data are often scarce due to high collection costs and privacy concerns, generating them from limited mobility observations o...

Seismic upgrading of an RC frame building using double-stage yield buckling-restrained braces

Nowadays, a large number of existing reinforced concrete (RC) structures require strengthening to meet the new building functions and enhanced seismic demands. Double-stage yield buckling-restrained braces (DYBRBs), capable of yielding at different seismic intensities, offer a pr...

Oxygen Plasma-Activated PES Ultrafiltration Substrates for Constructing High-Performance Mg2+/Li + Separation Nanofiltration Membranes

Abstract Positively charged polyamide (PA) nanofiltration (NF) membranes hold great potential for Mg2+/Li+ separation, but their performance is strongly affected by the surface properties and pore structures of the substrate. In this study, a PES ultrafiltration substrate was pre...

Sustainable by All-Biobased Design: Recyclable Flax Fiber/Silk Matrix Composites with Machine Learning-Assisted Mechanical Performance Prediction
