Using confocal microscopy and image processing to measure properties of sub‐resolution cell structures: Application to cardiac transverse tubules

Journal of Microscopy, EarlyView.
Abstract Confocal microscopes increase the resolution of images by rejecting unwanted data from the out of focus regions of the specimen. This incurs a penalty in the recorded signal to noise ratio that may be partially ameliorated by inputting additional information during image processing.

The Origins of Ploem's Filter Cube: A Pandora's Box

Journal of Microscopy, EarlyView.
Abstract Ploem's filter cube, central to modern epifluorescence microscopy, integrates three matched optical components: an excitation filter, an emission filter, and a dichroic mirror. Together, these elements enable the separation of excitation and emission light paths, producing high‐contrast fluorescence images.

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

Meteoritics &Planetary Science, EarlyView.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

An Analysis of Wrist Motions During Daily Activities From a Directional Perspective: The Significance of Directions Beyond the Dart‐Throwing Motion

Orthopaedic Surgery, Volume 17, Issue 5, Page 1486-1502, May 2025.
The study using an optical capture system revealed the directional characteristics of wrist functional motion. The results highlighted the directional range of motion (ROM), differences in preferences between genders and age groups, and identified three key directions most frequently utilized.

Measurement and modeling of diffuse ultraviolet radiation: A review

Photochemistry and Photobiology, EarlyView.
Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.
