The Particle as a Statistical Ensemble of Events in Stueckelberg–Horwitz–Piron Electrodynamics

open access: yesEntropy, 2017
In classical Maxwell electrodynamics, charged particles following deterministic trajectories are described by currents that induce fields, mediating interactions with other particles. Statistical methods are used when needed to treat complex particle and/

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China

open access: yesHigh Voltage, EarlyView.
ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Microwave single-tone optomechanics in the classical regime

open access: yesNew Journal of Physics, 2021
We report on the quantitative experimental illustration of elementary optomechanics within the classical regime. All measurements are performed in a commercial dilution refrigerator on a mesoscopic drumhead aluminium resonator strongly coupled to a ...

Wave Tracing: Generalizing The Path Integral To Wave Optics

open access: yesComputer Graphics Forum, EarlyView.
Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.

WPTherml: A Python Package for the Design of Materials for Harnessing Heat

open access: yesJournal of Open Research Software, 2019
WPTherml is a Python package for the design of materials with tailored optical and thermal properties for the vast number of energy applications where control of absorption and emission of radiation, or conversion of heat to radiation or vice versa, is ...

Scalar QED as a toy model for higher-order effects in classical gravitational scattering

open access: yesJournal of High Energy Physics, 2022
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED.

Assessment of MR‐Induced Heating Effects in Four Common Veterinary Implants at 1.5 and 3.0 T: A Phantom Study

open access: yesVeterinary 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 ...

Mathematical model I. Electron and quantum mechanics

open access: yesAIP Advances, 2011
The basic particle electron obeys various theories like electrodynamics, quantum mechanics and special relativity. Particle under different experimental conditions behaves differently, allowing us to observe different characteristics which become basis ...
