Why grounded large language models fail without domain-specialized retrieval: an experimental scientometric study in solar physics

Abstract Recent applications of large language models (LLMs) in scientometric analysis often assume that the underlying evidence space is neutral and pre-given. We challenge this assumption empirically by demonstrating that retrieval infrastructure constitutes a methodologically...

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk-fill (Filtek One Bulk Fill [FO] and Beautifil-Bulk [BB]) composites were evaluated. Cylindrical sp...

Effects of Dapagliflozin on the Bone of Patients with CKD on Dialysis

The effects of gliflozins on bones of CKD patients on dialysis are unknown. Recently, SGLT2 expression in bone tissue of patients with CKD has been reported. We hypothesized that dapagliflozin may act in bone cells and modulate the Klotho-FGF23 axis. This study analyzed the effec...

Validation of the AO Spine Osteoporotic Fracture Classification—effect of geographical region on reliability and reproducibility

Regional differences affect the reliability of the AO Spine-DGOU Osteoporotic Fracture Classification. European participants showed the highest agreement. This study underscores the need for addressing regional factors to improve the system’s global clinical utility. To evaluate...

Hitherto UnrecognizedIntermolecular Coulombic DecayMechanism in Gases

Abstract Excited atoms and molecules can utilize their excess energy to ionize a neighboring system by a process named interatomic and intermolecular Coulombic decay (ICD). ICD is ultrafast, in the femtosecond regime, and has many modes of appearance. Ample applications of ICD ha...

Matrix-DependentPerformance of β-GlucanComposite Films Functionalized with Phenolics from Passion Fruit SeedWaste

Abstract The valorization of agro-industrial waste for producing sustainable and functional packaging is a key strategy within the circular economy and green chemistry. This study developed active antioxidant edible films by incorporating a phenolic-rich extract from yellow passi...

Strain and Shear Wave Elastography in Thyroid Nodules: Tissue Stiffness as a Complementary Risk Marker for Differentiating Benign, Indeterminate, and Malignant Cytology

ABSTRACT Objective To evaluate the diagnostic performance of shear wave elastography (SWE) and strain elastography (SE) as complementary techniques to conventional B‐mode ultrasound for differentiating benign, indeterminate, and malignant thyroid nodules. Methods This prospective...

Intrinsic fire safety margins in reinforced concrete columns and shear walls resulting from ambient-temperature design

Fire design procedures for RC columns and shear walls assume that structures are designed according to ambient-temperature (AT) standards, whose partial safety factors can provide an intrinsic fire safety margin. However, the magnitude of this margin in fire behavior has not yet...

An Explainable Machine Learning Framework for Hypothesis Generation in Biochemical Methane Potential Prediction

Abstract Biochemical methane potential (BMP) assays are widely used to evaluate feedstocks for anaerobic digestion, but they are slow and resource-intensive. This study evaluated whether explainable machine learning can support transparent screening and hypothesis generation from...

Ten-Year Evaluation of Quality Control Indicators in a Brazilian Human Milk Bank

Background: Human milk banks play a critical role in neonatal care by providing donor human milk when maternal milk is unavailable, particularly for preterm and medically vulnerable infants. Despite global expansion, long-term evaluations of discard rates and quality indicators r...

Grid-Aware Bi-Level Optimization for Truck–Drone Routing: Integrating Grid Feasibility and Shadow Pricing

Electric trucks operating as mobile depots for delivery drones are promising for last-mile logistics, yet fleet electrification makes depot charging a critical issue governed by distribution-grid limits. Existing truck–drone routing formulations omit the electrical network, treat...

Smart Coatings Integrating Antimicrobial and Tissue‐Remodeling Functions for Implant Interfaces

AIM: This study aimed to assess the antimicrobial performance and biocompatibility of our drug delivery platform, based on layer-by-layer (LbL) coating incorporating tetracycline (TC) complexed with anionic β-cyclodextrin (TCβCD) and a pH-responsive poly(methacrylic acid) (PMAA)...

Range of dose enhancement factor for gold nanoparticles in radiotherapy using Monte Carlo simulations

Abstract Gold nanoparticles (GNPs) have been widely investigated as radiosensitizers in preclinical radiotherapy studies and are now advancing into clinical trials. To enhance tumour targeting, various molecular vectors are conjugated with GNPs. The localized radiation energy dep...

A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also org...
