Field-induced charge transport at the surface of pentacene single crystals: a method to study charge dynamics of 2D electron systems in organic crystals [PDF]

J. Appl. Phys. Vol. 94, pp. 5800-5804 (2003), 2003
A method has been developed to inject mobile charges at the surface of organic molecular crystals, and the DC transport of field-induced holes has been measured at the surface of pentacene single crystals. To minimize damage to the soft and fragile surface, the crystals are attached to a pre-fabricated substrate which incorporates a gate dielectric ...

Influence of artificial tears on corneal parameter measurement using three different devices: Keratometry and Scheimpflug technology, a randomized trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the effect of artificial tear (AT) application on the repeatability of corneal parameters with three different devices. Methods In this prospective, randomized clinical trial, 145 patients were measured with one of three devices in the Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Comparison of Diaton transpalpebral tonometer with applanation tonometry in keratoconus [PDF]

International Journal of Ophthalmology, 2016
AIM: To investigate the added value of using a Diaton transpalpebral tonometer (DT) to measure IOP in keratoconus. Most type of tonometers use corneal applanation or biomechanical resistance to measure intraocular pressure (IOP); however, these factors ...

Detecting Glaucoma in Highly Myopic Eyes From Fundus Photographs Using Deep Convolutional Neural Networks

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background High myopia (HM) is a major risk factor for glaucoma. However, glaucomatous optic neuropathy is often undiagnosed owing to atypical structural alterations with axial elongation. Moreover, an algorithm to detect glaucoma in highly myopic eyes has not yet been reported.

Deep Time-Delay Reservoir Computing: Dynamics and Memory Capacity [PDF]

arXiv, 2020
The Deep Time-Delay Reservoir Computing concept utilizes unidirectionally connected systems with time-delays for supervised learning. We present how the dynamical properties of a deep Ikeda-based reservoir are related to its memory capacity (MC) and how that can be used for optimization.

Validation of Recalibrated TONOVET Plus and TONOVET Pro in Canine Eyes Compared to Manometer and TONOVET

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To evaluate the accuracy of recalibrated TONOVET Plus (rTVP) and the newly released TONOVET Pro (TVPR) in measuring intraocular pressure (IOP) in ex vivo canine eyes compared to manometer and the established TONOVET (TV). Procedure Sixteen enucleated canine eyes were cannulated to establish manometric IOPs ranging from 5 to 80 mmHg ...
