Veterinary Radiology &Ultrasound, Volume 67, Issue 5, September 2026.ABSTRACT Quantitative evaluation of implant‐related heating in magnetic resonance imaging (MRI) is well standardized in human medicine, whereas evidence in veterinary medicine remains scarce. To address this gap, we measured radiofrequency (RF)‐induced heating of four used veterinary implants under controlled conditions on clinical 3.0 and 1.5 T MRI ...

Inverse Drexhage Effect in Epsilon‐Near‐Zero Substrates
Nanophotonics, Volume 15, Issue 15, 13 August 2026.Radiative emission of dipoles near substrates is shown to reverse between (a) perfect electric conductors and (b) epsilon‐near‐zero (ENZ) media. The schematic highlights switch from vertical to horizontal dipole dominance, governed by interference with image dipoles, leading to directional emission into the upper half‐space and enabling new strategies ...

Extended symmetrical classical electrodynamics [PDF]
Physical Review E, 2008 In the present article, we discuss a modification of classical electrodynamics in which ``ordinary'' point charges are absent. The modified equations contain additional terms describing the induced charges and currents. The densities of the induced charges and currents depend on the vector k and the vectors of the electromagnetic field E and B.

Optical Responses From Zero Optical‐Path‐Length Object
Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work address a fundamental question—what is the ultimately minimal embodiment of optical objects that produce useful optical effects? In fact, such an object does not require nonzero physical and optical‐path‐length volume as opposed to the conventional perception.

Aplikasi Aljabar Geometris Pada Teori Elektrodinamika Klasik
Jurnal Fourier, 2012 In this paper geometric algebra and its aplication in the theory of classical electrodynamic will be studied. Geometric algebra provide many simplification and new insight in the theoretical formulation and physical aplication of theory.

Advanced Science, Volume 13, Issue 44, 7 August 2026.A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

Energy Science &Engineering, Volume 14, Issue 8, Page 3862-3877, August 2026.This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.

Classical electrodynamics in a space with spin noncommutativity of coordinates
Physics Letters B, 2016 We propose a relativistic Lorentz-invariant spin-noncommutative algebra. Using the Weyl ordering of noncommutative position operators, we find a mapping from a space of commutative functions into space of noncommutative functions.

Supercritical Angle Fluorescence and Raman Techniques in Biophotonics
Laser &Photonics Reviews, Volume 20, Issue 15, 7 August 2026.Supercritical angle fluorescence (SAF) microscopy and supercritical angle Raman (SAR) spectroscopy have emerged as powerful tools in the field of biophotonics, enabling high‐resolution imaging and spectroscopy of biological specimens near interfaces. This review article provides a comprehensive overview of the principles, techniques, applications, and ...
