Effects of defocus and pupil size on human contrast sensitivity
, 1999 Defocus lowers the contrast sensitivity function (CSF), producing a complex function with local dips and peaks. Previously, we were able to predict the shape of the CSF with large pupils from measured transverse aberrations with hypermetropic defocus ...

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 ...

The Lord of the Rings: Cysteine bonds crosslink the tail of siphovirus
Protein Science, Volume 35, Issue 10, October 2026.Abstract Long, non‐contractile tails composed of helical hexameric protein repeats that assemble into continuous tubular structures characterize siphoviruses. The siphovirus tail tube protein gp39 contains two cysteine residues per monomer. Cryo‐electron microscopy revealed that these cysteines are oriented toward the interface between the rings, which

The lower γ region supports forward rotation in the latter half of the 80° substep of F1‐ATPase
Protein Science, Volume 35, Issue 10, October 2026.Abstract F1‐ATPase achieves unidirectional rotation of its γ shaft through coordinated conformational cycling of the α3β3 ring, yet how shaft–ring interactions contribute to the directionality of rotation remains unclear. Here we analyzed an axle‐less TF1, in which the lower γ region is truncated, by combining single‐molecule rotation assays with cryo ...

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like
