Acute corneal hydrops in keratoconus

open access: yesIndian Journal of Ophthalmology, 2013
Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain.

Long-term results of cornea collagen cross-linking with riboflavin for keratoconus

open access: yesIndian Journal of Ophthalmology, 2013
Corneal collagen cross-linking with riboflavin and UVA light (CXL) is the only method designed to arrest the progression of keratoconus. Visual improvement generally starts 3 months after treatment.

Hardness, Modulus, and Refractive Index of Plasma-Assisted Atomic-Layer-Deposited Hafnium Oxide Thin Films Doped with Aluminum Oxide

open access: yesNanomaterials, 2023
Coatings with tunable refractive index and high mechanical resilience are useful in optical systems. In this work, thin films of HfO2 doped with Al2O3 were deposited on silicon at 300 °C by using plasma-enhanced atomic layer deposition (PE-ALD).

Extracellular Vesicles Derived from Primary Adipose Stromal Cells Induce Elastin and Collagen Deposition by Smooth Muscle Cells within 3D Fibrin Gel Culture

open access: yesBioengineering, 2021
Macromolecular components of the vascular extracellular matrix (ECM), particularly elastic fibers and collagen fibers, are critical for the proper physiological function of arteries. When the unique biomechanical combination of these fibers is disrupted,

Modulus of edge covers and stars [PDF]

open access: yesarXiv, 2023
This paper explores the modulus (discrete $p$-modulus) of the family of edge covers on a discrete graph. This modulus is closely related to that of the larger family of fractional edge covers; the modulus of the latter family is guaranteed to approximate the modulus of the former within a multiplicative factor.

The Minimum Modulus of Polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
In answer to a problem of Erdös and Littlewood we produce an n n th degree polynomial, P ( z ) P(z) , with coefficients bounded by 1 satisfying | P ( z ) | > C n |P(z)
