Evaluation of the stray radiation distribution around a mobile cone beam computed tomography system in a simulated operating room environment

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Radiation protection in the operating room (OR) environment is a subject of much discussion in both the surgery and medical physics communities. Radiation exposure is often infrequent during image‐guided procedures, especially when only 3D imaging for navigation is used.

Caffarelli–Kohn–Nirenberg inequality for biharmonic equations with inhomogeneous term and Rellich potential

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
In this article, multiplicity of nontrivial solutions for an inhomogeneous singular biharmonic equation with Rellich potential are studied. Firstly, a negative energy solution of the studied equations is achieved via the Ekeland's variational principle ...

A Novel Form of Multiplicative Gamma Function and Its Analytical Properties

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
In this article, we introduce and investigate a novel Euler‐style multiplicative gamma function formulated within the framework of multiplicative calculus. This function is defined via a multiplicative integral and serves as a multiplicative analogue of the classical gamma function.

A mathematical model for a steady-state seepage flow of groundwater under a reinforced concrete dam

open access: yesApplied Computing and Geosciences, 2019
A numerical technique is applied to solve a biharmonic equation problem of a steady-state seepage flow of water through a thin layer of soil, under an impermeable dam.

An Intrinsic Version of the k-Harmonic Equation

open access: yesMathematics, 2023
The notion of k-harmonic curves is associated with the kth-order variational problem defined by the k-energy functional. The present paper gives a geometric formulation of this higher-order variational problem on a Riemannian manifold M and describes a ...

Spatial Decay Estimates for Elastic Plate System With Type II Heat Conduction

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
The classical Saint‐Venant principle has been extensively studied for harmonic and biharmonic models but remains largely unexplored for thermomechanical plates governed by hyperbolic (Type II) heat conduction, a conservative thermal model with unique dynamical features. This paper investigates the spatial decay properties of solutions to such a coupled

Transfer Learning With CLIP for Intelligent Concrete Crack Detection in Structural Health Monitoring

open access: yesShock and Vibration, Volume 2026, Issue 1, 2026.
Automated detection of surface cracks in concrete structures is a fundamental requirement for effective structural health monitoring and preventive maintenance. Conventional computer vision and convolutional neural network‐based approaches often suffer from limited generalization under variations in illumination, surface texture, and crack morphology ...

Splines, biharmonic operator and approximate eigenvalue

open access: yesСовременная математика: Фундаментальные направления
The biharmonic operator plays a central role in a wide array of physical models, such as elasticity theory and the streamfunction formulation of the Navier–Stokes equations. Its spectral theory has been extensively studied.
