How Far Are Two Symmetric Matrices From Commuting? With an Application to Object Characterisation and Identification in Metal Detection

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1914-1942, February 2026.
ABSTRACT Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed, and the Riemannian and Euclidean metrics are applied. However, if rotation matrices are not directly measured and are instead formed by eigenvectors of measured symmetric ...

Mindfulness Level Influences the Frequency, Amplitude and Duration of Awake Bruxism Episodes During Standardised Mental Capacity Tasks

Journal of Oral Rehabilitation, Volume 53, Issue 2, Page 579-591, February 2026.
Graphical representation of the study evaluating the influence of dispositional mindfulness on the frequency, amplitude, and duration of awake bruxism (AB) episodes during standardised mental capacity tasks. Sixty‐eight adult dental students underwent assessment with the BruxScreen questionnaire, the Five Facet Mindfulness Questionnaire (FFMQ ...

On the Energy Source of Green Emissions in Ghost

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The understanding on the formation mechanism of ghosts as a new category of transient luminous events and favorable conditions for their occurrence is limited. In this work, we examined six ground‐based observations of ghost events captured by digital SLR cameras.

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

FEBS Open Bio, Volume 16, Issue 1, Page 25-40, January 2026.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...
