Controlling Polymer Capture and Translocation by Electrostatic Polymer-Pore Interactions [PDF]

open access: yes, 2017
Polymer translocation experiments typically involve anionic polyelectrolytes such as DNA molecules driven through negatively charged nanopores. Quantitative modelling of polymer capture to the nanopore followed by translocation therefore necessitates the

Molecular mechanisms separating two axonal pathways during embryonic development of the avian optic tectum [PDF]

open access: yes, 1991
During embryonic development of the avian optic tectum, retinal and tectobulbar axons form an orthogonal array of nerve processes. Growing axons of both tracts are transiently very closely apposed to each other. Despite this spatial proximity, axons from

Diabetic Macular Edema With and Without Subfoveal Neuroretinal Detachment: Two Different Morphologic and Functional Entities [PDF]

open access: yes, 2017
To assess specific morphologic and functional characteristics in eyes with diabetic macular edema (DME) with subfoveal neuroretinal detachment (SND+) vs DME without SND (SND-)

Outer Retinal Microstructure in a Case of Acute Idiopathic Blind Spot Enlargement Syndrome

open access: yesCase Reports in Ophthalmology, 2011
Purpose: To present a patient with acute idiopathic blind spot enlargement syndrome who had abnormal changes in the outer retinal microstructure limited to areas with reduced responses on multifocal electroretinograms as well as to the area involving a ...

Dysflective cones: Visual function and cone reflectivity in long-term follow-up of acute bilateral foveolitis. [PDF]

open access: yes, 2017
PURPOSE:Confocal adaptive optics scanning laser ophthalmoscope (AOSLO) images provide a sensitive measure of cone structure. However, the relationship between structural findings of diminished cone reflectivity and visual function is unclear.

Analysis and theory of gas transport in microporous sol-gel derived ceramic membranes [PDF]

open access: yes, 1995
Sol-gel modification of mesoporous alumina membranes is a very successful technique to improve gas separation performance. Due to the formed microporous top layer, the membranes show activated transport and molecular sieve-like separation factors.

Implications of inhomogeneous distribution of concentration polarization for interpretation of pressure-driven [PDF]

open access: yes, 2016
A number of CFD studies have demonstrated that there is a considerable inhomogeneity of extent of Concentration Polarization (CP) over the membrane surface especially in spacer-filled feed channels. However, the consequences of this inhomogeneity for the

Surgical outcomes in patients with lamellar macular holes selected based on the optical coherence tomography consensus definition

open access: yesInternational Journal of Retina and Vitreous, 2021
Purpose The surgical indication for lamellar macular holes (LMH) is controversial due to a misclassification of different macular diseases. A consensus based on an optical coherence tomography (OCT) definition has recently been suggested. The aim of this

Current-induced membrane discharge [PDF]

open access: yes, 2012
Possible mechanisms for over-limiting current (OLC) through aqueous ion-exchange membranes (exceeding diffusion limitation) have been debated for half a century.

Strength determination for band-loaded thin cylinders [PDF]

open access: yes, 2018
Cylindrical shells are often subjected to local inward loads normal to the shell that arise over restricted zones. A simple axisymmetric example is that of the ring-loaded cylinder, in which an inward line load around the circumference causes either ...
