Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Understanding higher‐order aberrations in keratoconus

Optometry and Vision Science, Volume 103, Issue 10, October 2026.
ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic refractive error, asymmetric corneal steepening generates complex optical ...

One‐Year Results of Accelerated Transepithelial Corneal Cross‐Linking for Progressive Keratoconus: A Prospective Interventional Study

Eye &ENT Research, Volume 3, Issue 3, Page 168-174, September 2026.
ABSTRACT Background Keratoconus is a progressive corneal ectatic disorder. Accelerated transepithelial corneal cross‐linking (ATE‐CXL) aims to halt progression while preserving the epithelium, but evidence on its 12‐month efficacy requires further evaluation.

Costello Syndrome Associated With Somatic Mosaicism of Rare p.Gly13Asp HRAS Variant: Expanding the Phenotypic Spectrum

Molecular Genetics &Genomic Medicine, Volume 14, Issue 9, September 2026.
We report a case of a 22‐year‐old woman with predominantly cutaneous involvement in whom whole‐exome sequencing from both blood‐ and hair‐derived DNA samples identified somatic mosaicism for the rare HRAS p.Gly13Asp variant. This case expands the phenotypic spectrum of Costello syndrome and underscores the importance of multitissue genomic analysis ...

Near-Capacity Irregular Bit-Interleaved Coded Modulation [PDF]

, 2008
An Irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregularity of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and the bit-to-symbol
