Ocular Oscillations

open access: yes, 1977
A variety of abnormal ocular oscillations consequent to brain stem and cerebellar dysfunction are described. The brain stem eye signs include: see-saw nystagmus, convergence-retraction nystagmus, down-beat nystagmus, ocular myoclonus, ocular bobbing, and

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Ocular Manifestations of Whiplash Injury [PDF]

open access: yesEuropean Medical Journal, 2016
Introduction: Whiplash or indirect injuries to the neck are a common occurrence because of motor vehicle collisions, in which the frequency of ocular complications is largely unknown.

Fuzzy Convergence

open access: yes, 2007
This work considers the problem of discovering areas of convergence of line-like shapes in an image. The motivating application is to use the convergence of the blood vessel network to automatically locate the optic nerve in an ocular fundus image.

Convergence Insufficiency in the Geriatric Population

open access: yes, 2021
SIGNIFICANCE The present study is the first population-based study to examine the prevalence of convergence insufficiency and its associations specifically in the geriatric population. Knowledge of the population-based determination of prevalence of this

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Prevalence of convergence insufficiency between 18 and 35 years and its relation to body mass index

open access: yesTNOA Journal of Ophthalmic Science and Research, 2019
Background: Convergence insufficiency (CI) is a common condition characterized by patient's inability to maintain binocular alignment on objects as they approach from distance to near. One study has found association between low body mass index (BMI) and

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.
