PURPOSE This study reports the characteristics of corneal higher order aberrations (HOAs) in eyes with normal topographic pattern using the Pentacam scheimpflug system. METHODS In this prospective, observational, comparative study, 165 eyes of 97 patients separated into five groups based on corneal topographic patterns were enrolled. All eyes received a comprehensive ophthalmologic examinatio...

PURPOSE In scanning laser polarimetry with variable corneal compensation (SLP-VCC), the macula is used as an intraocular polarimeter to calculate and neutralize corneal birefringence based on an intact Henle's layer. The purpose of this investigation was to validate this strategy in eyes with macular structural disease. METHODS A nerve fiber analyzer was modified to enable the measurement of ...

Cyber-attacks pose a growing threat to global commerce that is increasingly reliant on digital technology conduct business. Traditional risk assessment and underwriting practices face serious shortcomings when encountered with cyber threats. Conventional frameworks rate based historical frequency severity of losses incurred, this method effective for known risks; however, due the absence data, ...

Top-down fabricated nanoantenna architectures of both metallic and dielectric materials demonstrated powerful functionalities for Raman fluorescence enhancement with relevance to single molecule sensing, while inducing directionality chromophore emission implications photon sources. Herein, we synthesize the smallest bowtie by selective tip-to-tip fusion two tetrahedral colloidal quantum dots (...

A new carboxylic acid functionalised cavitand forms [Cu(3)L(2)] metallo-cryptophanes with Cu(OAc)(2) that can be linked together into dimers with the bridging ligand 1,2-bis(4-pyridyl)ethylene. Reaction of the cavitand with Co(OAc)(2) gives a metallo-cryptophane with a central Co(7) cluster.
