Using an asymptotic formalism we developed in an earlier paper, we compare the dispersion properties of the air-core Bragg fiber with those of the coaxial Bragg fiber. In particular we are interested in the way the inner core of the coaxial fiber influence the dispersion relation. It is shown that, given appropriate structural parameters, large single-mode frequency windows with a zero-dispersi...

Purpose: To compare the outcomes of coaxial microincision phacoemulsification with that of conventional coaxial phacoemulsification SETTING: Department of Ophthalmology, Farabi and Noor Eye Hospitals, Tehran, Iran Methods: In a prospective study, 74 eyes of 74 patients with cataract were randomly selected to have cataract extraction using 1 of 2 techniques: coaxial microincision phacoemulsifica...

The formation mechanism of a coaxial manganese oxide/poly(3,4-ethylenedioxythiophene) (MnO(2)/PEDOT) nanowire is elucidated herein by performing electrodeposition of MnO(2) and PEDOT on Au-sputtered nanoelectrodes with different shapes (ring and flat-top, respectively) within the 200 nm diameter pores of an anodized aluminum oxide (AAO) template. It is found that PEDOT prefers to grow on the sh...

I would like to present our experiences with torsional and micro-coaxial technology on behalf of our French research group. My goal is to demonstrate to surgeons the transition from performing phacoemulsification with traditional longitudinal ultrasound to a micro-coaxial procedure using torsional technology. The impetus for the development of micro-incisional phacoemulsification was to provide...

BACKGROUND Advances in optogenetics have led to first reports of expression of light-gated ion-channels in non-human primates (NHPs). However, a major obstacle preventing effective application of optogenetics in NHPs and translation to optogenetic therapeutics is the absence of compatible multifunction optoelectronic probes for (1) precision light delivery, (2) low-interference electrophysiolog...

PURPOSE To assess changes in intraocular pressure (IOP) during standard coaxial or bimanual microincision phacoemulsification. SETTING Oregon Eye Center, Eugene, Oregon, USA. METHODS Bimanual microincision phacoemulsification (microphaco) was performed in 3 cadaver eyes, and standard coaxial phacoemulsification was performed in 1 cadaver eye. A pressure transducer placed in the vitreous cav...

We designed a specially designed coaxial spinneret in this study. The inner stainless-steel needle was connected to the inner plastic syringe just like the traditional one. The outer stainless-steel needle was replaced by a plastic nozzle, and connected to the outer plastic syringe. The tip of the inner stainless-steel needle was shortened 2 cm from the tip of the outer plastic nozzle. This str...

A broadband method for measurement of devices for counteracting cable effects is proposed. A magnetic dipole source is emulated by an electrically small shielded-loop probe next to a coaxial cable. Measurement results for a typical 890 MHz coaxial sleeve balun are presented.
