Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

Uniqueness and examples of compact toric Sasaki-Einstein metrics

, 2007
In [11] it was proved that, given a compact toric Sasaki manifold of positive basic first Chern class and trivial first Chern class of the contact bundle, one can find a deformed Sasaki structure on which a Sasaki-Einstein metric exists.

Political and Institutional Development in England

The Manchester School, EarlyView.
ABSTRACT This paper revisits the political and institutional development of England from the Magna Carta to the Glorious Revolution. I argue that institutional change in this period is best understood through the lens of coalition formation. Political elites had heterogeneous preferences over first two, and then three, recurring axes of disagreement ...

Surgical technique for management of isolated lenticular coloboma with high corneal astigmatism

Indian Journal of Ophthalmology, 2018
We describe a surgical technique for the correction of isolated congenital lenticular coloboma associated with high corneal astigmatism. Transscleral fixation of the capsular bag with a single eyelet Cionni capsular tension ring was followed by in-the ...

Matrix Model as a Mirror of Chern-Simons Theory

, 2002
Using mirror symmetry, we show that Chern-Simons theory on certain manifolds such as lens spaces reduces to a novel class of Hermitian matrix models, where the measure is that of unitary matrix models.

Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency: Results From a High‐Resolution Global Circulation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract As global circulation models (GCMs) have increased in spatial resolution, more realistic tropical cyclones (TCs) and TC distributions have been simulated. Whereas prior research on TC climatologies has relied on proxies like Potential Intensity and synthetic storm models, the cyclones simulated by newer TC‐resolving GCMs can now be analyzed ...

How Changing Narratives About the Future Shape Policymaking for the Long Term

European Policy Analysis, Volume 12, Issue 2, Spring 2026.
ABSTRACT How can we explain decisions by governments to engage in policy investments—accepting short‐term costs in return for anticipated gains in the longer term—after previously sustaining the status quo? Our article examines the role of narratives in changing expectations about the future as a key driver of intertemporal policymaking. In light of an
