Epi-LASIK Versus Epi-LASEK

Journal of Refractive Surgery, 2008
Purpose: To compare the possible advantages and disadvantages of adding an alcohol solution (20%) to the epi-LASIK procedure. This study focuses on flap making, haze, and pain with and without alcohol. Methods: A prospective study was performed on 45 patients to ...

Epi-superfluous submodules and epi-Artinian modules

Rendiconti del Circolo Matematico di Palermo Series 2, 2023
All rings in this review are associative with identity and all modules are unitary right modules. A submodule \(N\) of an \(R\)-module \(M\) is called epi-superfluous in \(M\) if for any submodule \(L\) of \(M,\) \(L+N=M\) implies that \(L\) is an epimorphic image of \(M.\) An \(R\)-module \(M\) is called epi-retractable if every non-zero submodule of \

An Evaluation of High-Resolution EPI sequences and Enhanced Image Reconstruction for fMRI at 7T: Siemens-EPI, CMRR-EPI and INM4-EPI

ISMRM Annual Meeting, 2023
EPI is of great importance in the MR community due to its wide applicability in various dynamic MR applications. Recent advances in EPI techniques extend its use for the depiction of neuronal activation with a cortical depth-dependence. Therefore, enhanced performance with reliable image quality is highly desirable in EPI.

A Note on Epi-Convergence

Canadian Mathematical Bulletin, 1994
AbstractLet LSC(X) denote the set of extended real valued lower semicontinuous functions on a metrizable space X. If f, f1, f2, f3,... is a sequence in LSC(X), we say 〈fn〉 is epi-convergent to f provided the sequence of epigraphs 〈epi fn〉 is Kuratowski- Painlevé convergent to epi f.

Preparation of 3-epi-ecdysone and 3-epi-20-hydroxyecdysone

Steroids, 1978
3-Dehydro-ecdysone and 3-dehydro-20-hydroxyecdysone were prepared and characterized. Reduction of these compounds with NaBH4 gave 3-epi-ecdysone and 3-epi-20-hydroxyecdysone, which were characterized fully by mass and p.m.r. spectrometry as well as by derivative formation.

The stereospecific synthesis of leukotriene A4 (LTA4), 5-epi-LTA4, 6-epi-LTA4 and 5-epi,6-epi-LTA4

Tetrahedron Letters, 1981
The stereospecific syntheses of the four isomers of 6-formyl-5,6-epoxy hexanoic acid methyl ester 8, 15, 23 and 30 from Z-deoxy-D-ribose have allowed the preparation of methyl esters of LTA4, 1, and its three unnatural isomers.

[Cross-Linking in Keratoconus: "Epi-off" or "Epi-on"?].

Klinische Monatsblatter fur Augenheilkunde, 2016
Corneal cross-linking can halt the progression of keratoconus, but what is the best approach for treatment? There are a number of treatment options for keratoconus, but only corneal cross-linking (CXL) appears to halt the progression of the disease. To guarantee effective cross-linking, CXL treatment involves removal of the corneal epithelium prior to ...
