The Concept of ākupeyar in Tamil Grammar A Historical and Comparative Perspective

This paper traces the history of the concept of the syntactic category ākupeyar ‘referent shifting noun’ in Tamil grammatical tradition and its transformation into a semantic category and the role of Sanskrit grammatical thoughts in the transformation. Theoretically limited numbe...

MRI Versus CT scan: A Comparative Analysis of Diagnostic Accuracy, Image Quality, Clinical Applications, and Patient Safety

Background: Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) are among the most important diagnostic imaging technologies used in contemporary healthcare. Although both modalities provide cross-sectional images of internal anatomical structures, they differ substanti...

Diagonal equity: bridging horizontal and vertical equity in public transport access

Abstract Equitable public transport (PT) provision requires balancing often competing principles: horizontal equity, serving population demand, and vertical equity, prioritizing social needs. This paper introduces diagonal equity, a novel metric integrating both dimensions into a...

USFGeoAI: Applying LLMs and Foundation Models to Assist in Image Retrieval

Abstract. Geospatial analysis is often hampered by two major obstacles: a scarcity of high-quality, annotated satellite imagery, and the complexity of interacting with machine learning tools for image analysis. To address this, we introduce USFGeoAI, a proof-of-concept system tha...

Identification of Early Stage Physiological Indicators for Summer Heat Resilience in Kimchi Cabbage (Brassica rapa L. ssp. pekinensis) via Integrated GWAS and Machine Learning

The production of Kimchi cabbage (Brassica rapa L. ssp. pekinensis) is increasingly threatened by concurrent heat and drought stress, which induce physiological disorders and severe heading failure. In this study, we implemented a dual-environment screening strategy to identify r...

Responsible Artificial Intelligence for Polypharmacy and Medication-Safety Risk in Older Adults: An Explainable FHIR-Based Clinical Decision-Support Framework

Medication-related harm in older adults is driven by the interaction of multimorbidity, age-related pharmacokinetic change, polypharmacy, potentially inappropriate medications, drug-drug interactions, fall-risk-increasing drugs and impaired renal function. Existing electronic pre...

Diagnostic Dilemma and Management Challenges in Fetal Tumors at a Tertiary Care Center: An Indian Experience

Abstract Fetal tumors often present late during pregnancy, posing diagnostic dilemmas and management challenges. A retrospective analysis of 11 pregnant women with fetal tumors attending the Fetal Medicine Unit of VMMC and Safdarjung Hospital, New Delhi, between June 2023 and May...

Spectroscopic insights into HD 133729: Probing the physical parameters of the first blue large-amplitude pulsator (BLAP) in a binary system

HD 133729 (TIC 75934024) remains to this day the only spectroscopically confirmed binary system in which one of the stars is a blue large-amplitude pulsator (BLAP). The known distance to the system (${D\approx 480}$ pc) reveals that the BLAP component (the secondary) is not only...

Beyond Entropy: Organization as the Preservation of Structural Identity

This work introduces a framework in which organization is defined as the degree to which identity-defining relationships among system states are preserved under transformation or perturbation. Existing descriptors such as energy, entropy, mutual information, and divergence measur...

Spatial patterns and factors associated with suicide death among individuals with suicide attempts in northern Iran

Suicide is a major global health concern causing over 720,000 annual deaths, with most occurring in low- and middle-income countries. Official reports in Iran demonstrate increasing and regionally varied patterns, with distinctly elevated risk levels observed in certain province....

Interested, able and prepared: stakeholders’ influence in local communities during the war in Ukraine

The capacity of local actors to step up and exert a positive influence in their communities has been a key focus of international assistance in the contemporary context of overlapping crises. The centralization of powers has appeared to diminish local stakeholders’ influence in c...

Migrant writing against mangling narratives: On Abdulrazak Gurnah’s use of humour

<ns5:p>Abdulrazak Gurnah has dedicated much of his oeuvre – consisting of eleven political novels – to ruminations on the nature of migration and spotlighting the travails of the refugees, as well as to grappling with what it means to move in the latter half of the 20th century f...

Flocculation and Dewatering Mechanisms of Pyrite Flotation Tailings: Synergistic Roles of Polyferric Chloride, Polydiallyldimethylammonium Chloride, and Skeleton Builders on Microstructure Evolution

This study investigates the conditioning and deep dewatering of pyrite tailings slurry using a composite system comprising polyferric chloride (PFC), polydiallyldimethylammonium chloride (PDMDAAC), and fly ash as a skeleton builder. The synergistic application significantly enhan...

Evaluating the strength and compressibility of kaolin clay stabilized with polypropylene columns

Abstract Building infrastructure on soft soil presents significant difficulties due to the soil’s high compressibility, low load-bearing capacity, and tendency for lateral deformation.Granular column techniques may decrease settlement in weak and soft soils by improving bearing c...

Synergistic experimental and ANN-based prediction of mechanical properties of basalt fiber reinforced high-strength concrete

This research focuses on how basalt macrofibers and microfibres affect the durability and Mechanical properties of M60 high-strength concrete. Compressive, split tensile, flexural strength, and acid resistance tests were employed to assess the performance of fiber-reinforced conc...

Fourier Analysis on Twisted Spaces, An introduction to the Möbius and Klein transforms — lecture notes for university students

An introductory set of notes for university students (BSc/MSc) on the Möbius and Kleintransforms. The starting point is an everyday phenomenon: many engineering and physical quantities are notperiodic but antiperiodic — after half a period they go over into their negative (half-w...

A Direction-Aware Lightweight Network for Camera-Based Underground Mine Track Region Segmentation

Accurate localization of the visible track region is essential for perception using front-mounted cameras on underground rail-guided mine vehicles. The task is difficult because the track foreground occupies only a small image area, and its boundary appearance changes with illumi...

Unsupervised dietary-behavioral profiling identifies PFAS (per- and polyfluoroalkyl substances) and metal exposure patterns in Korean adults

Abstract Beyond “what and how much you eat,” modern nutritional epidemiology is paying attention to how dietary and behavioral patterns, which combine food selection and the context of cooking, packaging, and ingestion, organize health and environmental exposure. This cross-secti...
