Extended Reality in Endodontics: A Review of Current Applications and Future Potential

International Endodontic Journal, EarlyView.
ABSTRACT Background Extended reality (XR) technologies, encompassing augmented reality (AR), virtual reality (VR), and mixed reality (MR), are increasingly used in endodontic education and practice. A gap exists regarding understanding of XR's applications and limitations among endodontic educators and practitioners.

Hyperspectral tomographic diffractive microscopy: Development and applications

Journal of Microscopy, EarlyView.
Abstract Tomographic Diffractive Microscopy (TDM) provides label‐free three‐dimensional imaging of transparent samples with resolution surpassing confocal limits. At IRIMAS, successive instrumental developments since 2009 have enhanced TDM capabilities through transmission, reflection, isotropic, polarisation‐sensitive, and dual‐view configurations ...

Exploring the Relationship Between a PST's Written Noticings of Student Mathematical Reasoning and Their Reported and Actual Viewing of a 360 Video

School Science and Mathematics, EarlyView.
ABSTRACT An essential aspect of mathematics teacher education is the development of professional noticing. A 360 video is a new technology that can aid in developing mathematical teacher noticing. This study examines the relationship between preservice teachers' noticing of mathematical student thinking and the variation in their physical focusing ...

Multitask Diffractive Deep Neural Networks Enabled by Joint Distance–Frequency Encoding

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
A joint distance–frequency encoding strategy enables a single passive diffractive neural network to switch among four computational tasks. By combining mechanically tunable layer spacing with a dual‐frequency phase‐independent metasurface, the same hardware performs orbital angular momentum classification, direction recognition, logic operations, and ...

Molecular Profiling of Pediatric Helicobacter pylori Gastritis Using Raman Spectroscopy: Spectral Patterns Corresponding to Local Biochemical Changes

Journal of Biophotonics, Volume 19, Issue 11, November 2026.
Raman microscopy at 532 nm reveals spectral differences between fresh gastric biopsies from children with Helicobacter pylori gastritis and uninfected controls. Patient‐level analysis identifies changes in the relative areas of 11 Raman bands, supporting rapid, label‐free mucosal phenotyping as a potential complement to histopathology.
