A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Implementation and Optimization of a Random Illumination Microscope: towards Robustness for Microscopy Core Facility

Biology of the Cell, Volume 118, Issue 3, March 2026.
We present the implementation of our RIM prototype within a microscopy core facility. We describe the system setup, characterization, and optimization, and, as a proof of concept, we provide biological examples demonstrating the prototype's performance, here in resolving microvilli brush border intestine in adult C. elegans.

3D imaging of neuronal inclusions and protein aggregates in human neurodegeneration by multiscale x‐ray phase‐contrast tomography

Brain Pathology, Volume 36, Issue 2, March 2026.
x‐ray phase‐contrast tomography enabled three‐dimensional, label‐free visualization and quantification of protein aggregates in neurodegenerative diseases with isotropic submicrometer resolution. The study revealed distinct electron density patterns in Lewy bodies, Hirano bodies, granulovacuolar degeneration, and amyloid plaques, highlighting their ...

Revisiting PSF models: Unifying framework and high‐performance implementation

Journal of Microscopy, Volume 301, Issue 3, Page 362-374, March 2026.
Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

A model of β‐adrenergic stimulation in human ventricular cells for tissue‐scale simulations of sympathetically modulated tachycardias

The Journal of Physiology, Volume 604, Issue 5, Page 1897-1914, 1 March 2026.
Abstract figure legend Modelling β‐adrenergic stimulation in sympathetically remodelled ventricular substrates. Myocardial infarction could result in sympathetic remodelling in ventricular tissues, which affects arrhythmia dynamics. However sympathetic remodelling is challenging to control experimentally; therefore we created an ionic model that ...

Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...
