ChemE-MTDS:Multi-Turn Dialogue Data Synthesis and Quality-Controlled Fine-Tuning for Chemical Engineering Large Language Models

Large language models (LLMs) have demonstrated remarkable capabilities in natural language understanding and reasoning. However, their performance in multi-turn dialogues within specialized domains, such as chemical engineering, remains limited due to the lack of high-quality, co...

MFG-E8 glycoprotein in inflammatory tissue regeneration: molecular mechanisms, therapeutic potential and advanced polymeric biomaterial delivery strategies

Milk fat globule epidermal growth factor 8 (MFG-E8) is a multifunctional glycoprotein that coordinates efferocytosis, inflammatory resolution, angiogenesis, and matrix remodeling during tissue repair. In ischemic and inflammatory microenvironments, endogenous MFG-E8 is functional...

A physics-guided generative framework for parameter-conditioned seismic damage visualization of bridge piers

ABSTRACT Traditional seismic damage assessment of reinforced concrete (RC) bridge piers relies on costly finite element (FE) simulations and subjective manual inspections. This study proposes a physics-guided conditional generative adversarial network (PG-CGAN) for continuous and...

How Structural Segmentation Shapes Petroleum‐System Efficiency in a Transform‐Modified Rift: Insights From the Saltpond Basin (Offshore Ghana), Equatorial Atlantic Margin

ABSTRACT Rifts host a substantial proportion of the world's hydrocarbon resources because lithospheric extension commonly generates sustained subsidence, thick sedimentary fills and laterally connected migration systems that enhance petroleum‐system efficiency. In transform‐modif...

Decoherence-protected entangling gates in a silicon carbide quantum node

Solid-state color centers are promising candidates for nodes in quantum network architectures. However, realizing scalable and fully functional quantum nodes-comprising both processor and memory qubits with high-fidelity universal gate operations-remains a central challenge in th...

Decoupled probabilistic modeling method for seismic-induced track irregularity on CRTS Ⅲ track-bridge system: Prediction and uncertainty quantification

Seismic-induced track irregularity (STI) is the key factor affecting train safety in high-speed railway bridges. Due to its high-dimensional spatial characteristics, direct prediction of STI may reduce modeling efficiency and prediction accuracy. More importantly, few existing mo...

Principles of Carbon Isotope Tracing and Its Applications in Energy Geology and Carbon Cycling: Progress, Challenges, and Prospects

Over the past several decades, the conceptual basis for carbon isotope tracing has steadily matured. The method’s high specificity and sensitivity have established it as a robust, widely adopted tool across soil, vegetation, ecology, and environmental research. This paper surveys...

Conformal PAA-Modified SnO2 Interfacial Layer for Efficient and Stable Sb2S3 Solar Cells

Abstract Sb2S3 is a promising thin-film photovoltaic absorber owing to its suitable band gap, high absorption coefficient, and earth-abundant composition. However, its performance remains limited by defect-induced carrier recombination and interfacial inhomogeneity at the electro...

Rhizosphere Microenvironment-Induced Transformation of Lithium Cobalt Oxide Triggers Singlet Oxygen and Plant Injury

Abstract Lithium cobalt oxide (LCO), a layered lithium-ion battery cathode material, undergoes pronounced chemical and structural reprogramming at the plant interface. Here we show that root-associated conditions convert LCO nanosheets into a high-aspect-ratio needle-like state w...

Auditory-inspired cross-attention learning of spectral and modulation signatures for ship recognition

Underwater ship recognition is fundamentally challenged by acoustic complexity and limited labeled data. This paper proposes a physics-driven multidimensional feature fusion (MDFF) framework via auditory-inspired cross-attention learning. Rather than relying on isolated acoustic...

Soundscape Heritage in Historic Environments: Implications for Authenticity-Oriented Sustainable Conservation

Heritage conservation has traditionally privileged what can be seen, yet the continuity and authenticity of historic environments also depend on what can be heard. Place-specific sounds can embody cultural memory, everyday practices, and local character, but their role in heritag...

Cell Cryoisolation and Cryopreservation without Any Organic Solvent

Abstract Cell isolation and banking face challenges, balancing cryoprotective efficacy, functional preservation, and isolation purity, requiring innovative approaches with specificity, scalability, and native functionality. We developed a transformative platform based on DNA nano...

Interpretable speech biomarkers of psychological resilience in major depressive disorder via expert-guided large language models

Abstract Background Major depressive disorder (MDD) is highly prevalent and recurrent, but current clinical care focuses mainly on symptom reduction, overlooking the individual’s capacity for psychological resilience which is a key factor for long-term recovery. Traditional resil...

Nanoconfinement of Ultrasmall Bismuth in Hard Carbon Enables Ultrahigh-Capacity Sodium-Ion Batteries at Low Temperatures

Abstract Electrochemical energy storage systems that perform reliably under low temperatures are crucial for applications in transportation, renewable energy buffering, and devices in harsh climates. Alloy-type anodes, particularly bismuth (Bi), are promising for low-temperature...
