Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

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 ...

Holographic memories

, 1997
Holographic memories can be read-out either with the reference or the signal beam. Reference beam read-out reconstructs the stored data whereas signal beam read-out performs a search of the stored data base.

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.
