Subdivision of metachronous metastatic nasopharyngeal carcinoma based on the framework of TNM-9: A recursive partitioning analysis of real-world data

Abstract Purpose: To validate the prognostic value of the M1 category in version nine of the AJCC/UICC TNM staging system (TNM-9) in metachronous metastatic nasopharyngeal carcinoma (mmNPC) and to develop a refined M1 classification for improved risk stratification. Methods: Pati...

Can Analytic Theology Provide a Symbolic Logical Framework for Moral Safeguards in Large Language Models?

Conversational AI deployed at population scale has begun to produce documented psychological harm, emotional bonding, affective dependence and behavioural influence on vulnerable users, with legal filings, regulatory complaints and public safety disclosures involving owners or de...

Measurement report: Quantifying the trade-off between station number and spatial layout in sparse GNSS networks for calibrating all-weather FY-4A precipitable water vapor

Abstract. Integrating satellite-derived precipitable water vapor (PWV) provides data with high spatiotemporal resolution, which is crucial for monitoring and forecasting extreme weather. However, current fusion and calibration methods typically relies on dense GNSS networks, hind...

Fitting two-level structural equation models to summary statistics: Leveling up meta-analytic structural equation modeling.

Standard two-level SEM models require access to raw data. In this study we propose a method for fitting two-level SEMs using meta-analytic structural equation modelling (MASEM) on sum-mary statistics. Although our focus is on the meta-analytic case of individuals nested in studie...

Enhancing disease surveillance in Nigeria through machine learning: opportunities, challenges and strategic recommendations

Abstract Disease surveillance is fundamental to public health, enabling timely outbreak detection, efficient resource allocation, and evidence-based policymaking. In Nigeria, the Integrated Disease Surveillance and Response (IDSR) framework, while structured, is hampered by incon...

Evidence for endemism and local adaptation in Antarctic soil bacteria

Antarctic soils represent one of the more extreme environments for microbial life on Earth, yet they harbor heterogeneous and diverse microbial communities. Biologists have long hypothesized that Antarctic microorganisms are unique from those found on other continents due to the...

Macroeconomic effects of progressive tax reform in Nigeria using synthetic control counterfactual and simulation analysis

Abstract This study examines the relationship between taxation structure and macroeconomic performance within a comparative panel of Nigeria, South Africa, the United Kingdom, and Canada over the period 2000–2024, while providing a forward-looking evaluation of Nigeria’s 2026 pro...

Practical irrigation scheduling at the sub-field scale: Comparing OpenET and capacitance soil moisture sensors against a TSEB reference in dry edible beans

Accurate estimation of daily crop evapotranspiration (ET) at the sub-field level is critical for precision irrigation scheduling and management, yet few studies have evaluated whether satellite-based ET products can resolve soil-driven spatial variability within a single field. W...

Efficacy and Safety of Stereotactic Body Radiation Therapy for Metastatic Bone Tumors in Clinical Practice

Abstract Background: The development of radiation techniques has demonstrated that stereotactic body radiation therapy (SBRT) effectively achieves good local control and long-term pain palliation for metastatic bone tumors. This study evaluated the efficacy and safety of SBRT for...

PAPER-Ω: Time from Geometry: Multi–Layer Temporality and Phase Locking in a Six–Dimensional Symplectic Framework

We formulate a typed architecture for temporality in a six–dimensional symplectic setting. Time is not inserted as one primitive background coordinate. Three geometric readouts are distinguished—Hamiltonian flow time, internal phase time, and effective Lorentzian time—and a fourt...

PAPER–Σ: Symplectic Foundations of Action, Global Structure, and Observable Readout

This paper develops a pre-metric symplectic foundation for action, global structure, and observable readout in the Fracture–Berry–Tension framework. Its central claim is deliberately narrower than a direct derivation of matter, gravity, dark sectors, black holes, or Hawking radia...

Spin-coherence characterization of boron vacancy defects in hexagonal boron nitride with broadband microwave pulses

Negatively charged boron vacancy (VB−) defects in hexagonal boron nitride (hBN) are promising for nanoscale-proximity quantum sensing. To evaluate their performance, it is important to characterize the spin-coherence times T2* and T2. In this study, we realized subgigahertz Rabi...

Boxing-related maxillofacial and orbital trauma: a retrospective NEISS database analysis of injury patterns and emergency diagnostic prioritization (2014–2023)

Abstract Introduction/Background: Using the National Electronic Injury Surveillance System (NEISS) database, this study analyzes boxing-related maxillofacial and orbital injuries presenting to emergency departments nationwide, identifying injury patterns to better equip clinician...

Submicrometer focusing of isolated attosecond XUV pulses approaching 1016 W/cm2

We demonstrate submicrometer focusing of isolated attosecond pulses (IAPs) in the extreme ultraviolet (XUV) region using a custom ellipsoidal mirror. The obtained focal spot sizes were verified using knife-edge measurements with a sharp silicon edge, confirming reproducible dimen...

Sensitivity Analysis of Short‐Term Frequency Stability to Post‐Contingency Active Power Increase and Support Duration from Deloaded Wind Turbines

The growing deployment of Type‐4 wind turbine generators (WTs), driven by carbon neutrality and net‐zero policies, may challenge frequency stability in power systems. Unlike synchronous generators, WTs connected to the power system via converters do not provide inertia. Neverthel...

The medico‐legal autopsy: medicine, expertise, and death investigation

Abstract This article sheds important new light on the hybrid space between medicine and law in which medico‐legal autopsies are situated. By examining original empirical data obtained during interviews with pathologists, I reveal a web of authority claims both within the profess...

PAPER-Θ: Structural Temperature and the Geometric Origin of Thermal Physics: A Four-Layer Foundational Framework

Temperature is not assumed here to be a primitive coordinate of geometry. The paper isolates three logically distinct thermal readouts. A branch structural temperature is an energy–entropy conjugate along a specified admissible one-dimensional family. An equilibrium Gibbs tempera...

Long-term effects of cognitive-behavioral therapy for adults with ADHD: results from an 8-year randomized controlled trial follow-up

Abstract Background To evaluate the provisional long-term durability of group cognitive behavioral therapy (CBT) benefits 8 years post-baseline and to explore tentative associations between digital booster engagement and the maintenance of treatment gains in adults with ADHD. Met...

Impact of high-volume GNSS Radio Occultation data on the Navy's global numerical weather prediction

Abstract. This study assesses the impact of assimilating high-volume Radio Occultation (RO) data from the RO modeling experiment (ROMEX) on the Navy's global operational Naval Global Environment Model (NAVGEM). A series of observation system experiments were conducted, including...

A Note on Coadjoint Orbits for Multifermion Systems

The coadjoint orbit action for a multifermion system, as an exact description of its dynamics, is considered. We also discuss two sequential approximations. The first involves a reduction to dynamics on the single-particle Hilbert space described by another coadjoint orbit action...
