Evaluation of deep learning‐based methods for automatic detection and segmentation of brain metastases in T1‐contrast MRI for stereotactic radiosurgery

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Brain metastases (BMs) are manually contoured during stereotactic radiosurgery (SRS) treatment planning, which is both time‐consuming and potentially inconsistent. To address these challenges, researchers have been actively developing deep learning‐based approaches for the detection and segmentation of BMs.

A note on equivalent interval covering systems for Hausdorff dimension on ℝ

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
The Hausdorff dimension of a set in ℝ is usually defined by considering countable coverings of the set by general intervals. In this note we establish sufficient conditions under which coverings whose members are restricted to a particular family g of ...

Quantification of head and neck cancer patients' anatomical changes during radiotherapy: Toward the prediction of replanning need

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Head and neck cancer (HNC) patients undergoing radiotherapy (RT) may experience anatomical changes during treatment, which can compromise the validity of the initial treatment plan, necessitating replanning. However, ad hoc replanning disrupts clinical workflows and increases workload.

Quantifying the Single‐Cell Morphological Landscape of Cellular Transdifferentiation through Force Field Reconstruction

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
This study reconstructs the driving force field of fibroblast‐to‐neuron transdifferentiation from sparse single‐cell images by decomposing it into flux and time‐dependent potential gradient, extending the landscape‐flux framework to non‐steady‐state systems.

Sparse potentials with fractional Hausdorff dimension

open access: yesJournal of Functional Analysis, 2004
We construct non-random bounded discrete half-line Schr\" odinger operators which have purely singular continuous spectral measures with fractional Hausdorff dimension (in some interval of energies). To do this we use suitable sparse potentials. Our results also apply to whole line operators, as well as to certain random operators.

Mind the Solid Side: Electrochemical Thermodynamics, Kinetics, and Hysteresis in Energy Materials

open access: yesChemElectroChem, Volume 13, Issue 1, January 2026.
This mini‐review presents the electrochemical thermodynamics, kinetics, and hysteresis in solid‐to‐solid electrochemical phase transformation under three distinct categories of regular solutions, Fickian diffusion models, and spinodal decomposition. It highlights the role of electrochemical modeling combined with galvanostatic and cyclic voltammetry ...

The Effects of Shoe Sole Thickness on Running Style and Stability During Downhill Running at Different Speeds

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 1, January 2026.
ABSTRACT Advanced footwear technologies (AFT) like carbon plates and thick, lightweight soles were developed to enhance running performance. Previous research on sole thickness focused on level running; however, downhill running, with different biomechanical demands, remains underexplored. This study investigates how running shoe sole thickness affects
