Lens System Adjustment in Semiconductor Lithography Equipment

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2008
In this paper, we address the problem of lens aberration adjustment for lenses of semiconductor lithography equipment. The objective of aberration adjustment is to minimize the maximum value of aberration in any part of the images that are projected on ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

The Individual Virtual Eye: a Computer Model for Advanced Intraocular Lens Calculation

open access: yesJournal of Optometry, 2009
Purpose: To describe the individual virtual eye, a computer model of a human eye with respect to its optical properties. It is based on measurements of an individual person and one of its major application is calculating intraocular lenses (IOLs) for ...

H.L. Liou and N.A. Brennan (1996) The prediction of spherical aberration with schematic eyes

open access: yes, 1998
I would like to point out three aspects of the paper 'The prediction of spherical aberration with schematic eyes' by Liou and Brennan (1996) which I believe are either misleading or ...

Aberration correction in abdominal histotripsy

open access: yes, 2023
In transabdominal histotripsy, ultrasound pulses are focused into the body to noninvasively destroy soft tissues via cavitation. However, the ability to focus is limited by phase aberration, or decorrelation of the ultrasound pulses due to spatial ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Longitudinal chromic aberration as a function of refractive error

open access: yes, 1993
The refractive error-dependence of longitudinal chromatic aberration was investigated, our hypothesis is being that myopia may be the outcome of inadequate cues to defocus.
