Numerical simulations of the quiet chromosphere

, 2010
Numerical simulations of the solar chromosphere have become increasingly realistic over the past 5 years. However, many observed chromospheric structures and behavior are not reproduced.

Numerical simulations of time resolved quantum electronics

, 2014
This paper discusses the technical aspects - mathematical and numerical - associated with the numerical simulations of a mesoscopic system in the time domain (i.e. beyond the single frequency AC limit).

Comprehensive end‐to‐end dosimetry audit for stereotactic body radiotherapy in spine, lung, and soft tissue

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Purpose To create and conduct a comprehensive onsite end‐to‐end dosimetry audit to assess treatment accuracy of spine, lung, and soft tissue Stereotactic Body Radiotherapy (SBRT) across Australian and New Zealand (ANZ) radiotherapy centers. Methods The Australian Clinical Dosimetry Service (ACDS) anthropomorphic thorax phantom underwent a CT ...

Global dynamical properties of two discrete-time exponential systems

Journal of Taibah University for Science, 2019
We explore the global dynamics of following three directional discrete-time exponential systems of difference equations: \[{x_{n + 1}} = \frac{{{\alpha _{19}} + {\beta _{19 }}{e^{ - {y_n}}}}}{{{\gamma _{19}} + {z_{n - 1}}}},\,\quad {y_{n + 1}} = \frac{{{\

Technical development and In Silico implementation of SyntheticMR in head and neck adaptive radiation therapy: A prospective R‐IDEAL stage 0/1 technology development report

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Background SyntheticMR has the capability of generating quantitative relaxometry maps and synthetic contrast‐weighted MRI images in rapid acquisition times. Recently, it has gained attention in the diagnostic community, however, no studies have investigated its feasibility on the MR‐Simulation or MR‐Linac systems, especially as part of the ...

Numerical simulations of coronal particle trapping [PDF]

, 1997
In this paper the trapping of high energy particles in solar coronal loops is addressed. Using simulations, the time evolution of electrons and protons trapped in a magnetic bottle is calculated under various scattering conditions and the results ...

Simulation‐free workflow for lattice radiation therapy using deep learning predicted synthetic computed tomography: A feasibility study

Journal of Applied Clinical Medical Physics, Volume 26, Issue 7, July 2025.
Abstract Purpose Lattice radiation therapy (LRT) is a form of spatially fractionated radiation therapy that allows increased total dose delivery aiming for improved treatment response without an increase in toxicities, commonly utilized for palliation of bulky tumors.
