Don’t Use a Cannon to Kill a Fly: Lightweight Model Editing for LLMs to Correct Deprecated API Recommendations

Pre-trained or fine-tuned on large code corpora, Large Language Models (LLMs) have demonstrated strong performance in code completion tasks. However, their embedded knowledge is constrained by the timeliness of training data, which often includes code using deprecated APIs. Conse...

Revisiting Path Coverage Tracing from a Node-Centric View

Path coverage tracing is one of the fundamental components for supporting a wide range of dynamic program analyses, such as testing, debugging, profiling, and many others. Since one needs to insert code into a program to trace its coverage, runtime overhead becomes the main bottl...

Landscape and mutational dynamics of G-quadruplexes across the complete human genome

Abstract Background G-quadruplexes (G4s) are alternative DNA structures with diverse biological roles, but their examination in highly repetitive parts of the human genome has been hindered by the lack of reliable sequencing technologies. Recent long-read based genome assemblies...

CRAFT: Exploring Wearable Creative AI on Smart Glasses for Fiction Writing in Real-World Contexts

Creative writing increasingly integrates AI assistance, yet current tools miss in-situ moments when writers draw inspiration from real-world experiences. We envision Context-aware Reality-Fiction Transformation ( CRAFT ), an approach for AI glasses that translates daily experienc...

Committed Antarctic Ice Sheet mass loss by the end of the twenty-first century

Abstract The Antarctic Ice Sheet is the largest source of uncertainty in sea-level rise projections, with uncertainties propagating through emissions scenarios, atmosphere–ocean general circulation models, ice-sheet dynamics and sea-level physics. In ice-sheet model intercomparis...

Bias‐Free Tactile Synaptic Ionogel With Viscoelastic Memory for Biomechanical Monitoring

ABSTRACT Endowing artificial skins with adaptation and sensory memory is essential for intelligent tactile perception. However, conventional transistor‐based neuromorphic systems rely on energy‐intensive, decoupled architectures that fundamentally constrain their structural flexi...

Stochastic mesoscale modeling of chloride ingress in coastal concrete structures under climate change

Climate change is intensifying chloride-induced corrosion in marine reinforced concrete (RC) structures, yet conventional durability assessment fails to capture the coupled effects of material heterogeneity, environmental variability, and thermo-hygro-ionic transport. This paper...

Elevated substrate preheating tailors microstructural evolution and enhances fatigue resistance in laser powder bed fusion H13 tool steel

Fatigue performance remains a key limitation for laser powder bed fusion (LPBF) tool steels due to the strong coupling between process-induced defects and microstructural heterogeneity. Elevated substrate preheating has been proposed as an effective strategy to improve the proces...

Bimetallic Sulfides for Next‐Generation Energy Systems: Structure‐Performance Correlations, Multidimensional Regulation, and Controllable Synthesis

ABSTRACT Bimetallic sulfides (BMSs) have emerged as promising candidates for advanced energy storage and conversion owing to their unique synergistic effects and tunable electronic configurations. However, their practical implementation is heavily hindered by intrinsic limitation...

Selective Photoelectrochemical Water Oxidation to Hydrogen Peroxide via Tip-Induced Interfacial Regulation

Abstract Bicarbonate (HCO3–) electrolytes have significantly promoted photoelectrochemical water oxidation to H2O2 production over the competitive O2 evolution. However, the selectivity and efficiency are still fundamentally constrained by the limited solubility of the HCO3–, the...

Personalized open-set intrusion detection with dynamic class discovery for heterogeneous Internet of Things

In Internet of Things(IoT) environments, most intrusion detection systems are trained under a static closed-set assumption, where attack categories are predefined, and the model is deployed without mechanisms for continuous adaptation. However, severe device heterogeneity and rap...

Extending the technology acceptance model with trust and perceived risk to explain young-old adults’ virtual reality technology adoption

Virtual reality (VR) technology is a valuable tool to address the evolving needs of young-old adults. This study investigated the factors influencing the adoption of VR technology among young-old adults, extending the technology acceptance model by incorporating trust and perceiv...

How locus of control shapes digital nomads’ subjective well-being: the mediating roles of telepressure, technostress, and boundary control

Abstract Background As digital nomadism becomes an increasingly prevalent form of digital labor, understanding how psychological mechanisms shape well-being under highly autonomous yet weakly institutionalized work conditions is critical. Drawing on the Job Demands–Resources (JD-...

Ab Initio Chemical Kinetics of Radical–Radical Reaction of CH3O with NO2

Abstract This work theoretically investigated the ab initio chemical kinetics of the radical–radical reaction between the methoxy (CH3O) and nitrogen dioxide (NO2), which represents a key C–N interaction in ammonia/hydrocarbon cocombustion. The stationary-point energies were dete...

Auditable Automation of Activated Sludge Modeling for Wastewater Treatment Diagnosis Using LLM-Agents

Abstract Wastewater treatment plants (WWTPs) need mechanistic models that explain carbon, nitrogen, and phosphorus transformations under changing operating conditions. Building activated sludge models (ASMs) still depends heavily on expert choices about boundaries, components, an...
