Rendering transparency to ranking in educational assessment via Bayesian comparative judgement

Review of Education, Volume 14, Issue 2, August 2026.
Abstract Transparency in educational assessment has become an increasingly pressing concern, particularly in the aftermath of the pandemic, as institutions seek more equitable, robust and defensible methods of evaluating student work. Comparative judgement (CJ) has gained traction as a promising alternative to traditional rubric‐based marking. However,

Uncertainty quantification of U‐Net based segmentation tool using conformal prediction

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The radiation therapy treatment process is very labour intensive, and artificial intelligence (AI) based auto contouring tools are increasingly being adopted to improve efficiency. However, current acceptance testing of AI auto contouring algorithms relies primarily on area‐ and distance‐based metrics, with limited assessment of ...

Infinity valued partial metrics

Applied General Topology
A partial metric is a generalised metric incorporating non-zero self-distance. It was introduced by Matthews in Computer Science, and connected well with Kopperman's long standing interest in generalised metrics and non-Hausdorff topology.

Order isomorphisms between bases of topologies

Extracta Mathematicae, 2022
In this paper we will study the representations of isomorphisms between bases of topological spaces. It turns out that the perfect setting for this study is that of regular open subsets of complete metric spaces, but we have been able to show some ...

Personalized eye protection for head CT organ‐based tube current modulation: A deep learning approach to derive 3D eyeball models from a single‐view topogram

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background The lens of the eye is highly radiosensitive, yet personalized shielding during head CT remains challenging due to the lack of a rapid, pre‐scan localization method. Purpose To develop and validate a deep learning solution that enables automated, patient‐specific eye protection by generating a precise 3D eyeball model directly from ...

Blinded, bias‐controlled multi‐rater evaluation of human‐versus‐AI brain metastasis segmentation using a hybrid foundation‐model framework

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate segmentation of brain metastases (BM) is essential for diagnosis, stereotactic radiosurgery planning, and longitudinal assessment. However, manual contouring is time‐intensive, limiting clinical scalability, and exhibits substantial inter‐observer variability.

Clinically Feasible White Matter Fiber Tractography in Peritumoral Zones With Cerebral Vasogenic Edema

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 287-301, July 2026.
ABSTRACT Purpose In diffusion MRI, vasogenic edema manifests as a major fraction of isotropic water that dilutes the anisotropic intra‐axonal portion of the signal. Many tractography algorithms mistake vasogenic edema for the white matter boundary and terminate tracking to prevent producing spurious streamlines.

Refined Modeling of Arctic Circumpolar Building Stock Increases Estimated Mid‐Century Permafrost Degradation Damages

Earth's Future, Volume 14, Issue 7, July 2026.
Abstract Near‐surface permafrost degradation has the potential to damage infrastructure needed to sustain Arctic communities, but risk assessments remain highly uncertain due to a limited representation of the Arctic circumpolar building stock. With deep learning building footprint detection and building occupancy classification models, we expand the ...
