Automated rapidplan model validation using Eclipse scripting API

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract RapidPlan offers efficiency gains and quality improvements in treatment planning. Prior to its use in the clinic, it requires an extensive validation procedure in which established clinical plans and those generated by the model are compared. The manual iterative nature of this process is resource intensive, as numerous iterations are required

On the Existence of Homogeneous Geodesics in Homogeneous Kropina Spaces

open access: yes, 2019
Recently, it is shown that each regular homogeneous Finsler space $M$ admits at least one homogeneous geodesic through any point $o\in M$. The purpose of this article is to study the existence of homogeneous geodesics on singular homogeneous $(\alpha ...

Heterogeneity in homogeneous nucleation from billion-atom molecular dynamics simulation of solidification of pure metal

open access: yesNature Communications, 2017
Can completely homogeneous nucleation occur? Large scale molecular dynamics simulations performed on a graphics-processing-unit rich supercomputer can shed light on this long-standing issue.

Beam model development and clinical experience with RadCalc for treatment plan quality assurance in online adaptive workflow with an MR‐linac

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The aim of this work was to report on the optimization, commissioning, and validation of a beam model using a commercial independent dose verification software RadCalc version 7.2 (Lifeline Software Inc, Tyler, TX, USA), along with 4 years of experience employing RadCalc for offline and online monitor unit (MU) verification on the ...

Homogeneity, quasi-homogeneity and differentiability of domains

open access: yesProceedings of the Japan Academy, Series A, Mathematical Sciences, 2003
In this paper we show that any convex quasi-homogeneous projective dornain whose boundary is everywhere twice differentiable except possibly at a finite number of points is homogeneous.

Dosimetric evaluation and clinical application of collimated apertures with proton beam line scanning in stereotactic radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Stereotactic radiotherapy (SRT) is a highly effective treatment with precision for small, localized lesions. Proton therapy, characterized by the Bragg peak, offers superior dose conformity compared to photon‐based approaches. However, challenges remain in minimizing lateral penumbra and optimizing dose delivery, particularly for small

Homogeneous 2-partite digraphs [PDF]

open access: yes, 2013
We call a 2-partite digraph D homogeneous if every isomorphism between finite induced subdigraphs that respects the 2-partition of D extends to an automorphism of D that does the same. In this note, we classify the homogeneous 2-partite digraphs.Comment:

The homogeneous coordinate ring of a toric variety

open access: yes, 2013
This paper will introduce the homogeneous coordinate ring S of a toric variety X . The ring S is a polynomial ring with one variable for each one-dimensional cone in the fan ∆ determining X , and S has a natural grading determined by the monoid of ...
