Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

open access: yesHigh Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

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

open access: yesActa Ophthalmologica, EarlyView.
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 ...

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

open access: yesActa Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

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

open access: yesBrain Pathology, EarlyView.
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 ...

Understanding Atrial Fibrillation Complexity Through the Lens of Turbulence Dynamics: Implications for Treatment Strategies

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these
