Development and Diagnostic Potential of a Handheld Probe Polarization‐Sensitive Optical Coherence Tomography in Oral Mucosa Imaging

International Journal of Imaging Systems and Technology, Volume 36, Issue 4, July 2026.
Handheld Probe Polarization‐Sensitive Optical Coherence Tomography for Oral Screening. ABSTRACT Early detection of oral cancer through routine screening is important. Therefore, developing noninvasive, good‐resolution, and cost‐effective screening tools that provide real‐time in vivo oral health imaging is paramount.

Students’ Experiences of Teachers’ Ways of Unpacking Visual Representations in the Context of Intermolecular Forces

Science Education, Volume 110, Issue 4, Page 1133-1151, July 2026.
ABSTRACT This is the third article in a series, emanating from a project that used social semiotics and phenomenography to explore the role visual representations play in the teaching and learning of chemistry. Building on our earlier work that identified five qualitatively different ways that teachers may use to unpack visual representations in their ...

Occurrence of Flat‐Top Electron Velocity Distributions in Magnetotail Plasma Jets

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Non‐Maxwellian electron velocity distributions (eVDFs) are ubiquitous in collisionless plasmas. For example, various types of non‐Maxwellian eVDFs exist in magnetic reconnection jets in the Earth's magnetotail. At thermal energies, eVDF can be flat‐topped due to electron trapping associated with magnetic reconnection.

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.
