Effectiveness of vision therapy in school children with symptomatic convergence insufficiency

open access: yesJournal of Ophthalmic & Vision Research, 2017
Purpose: To determine the effectiveness of vision therapy among Korean elementary school children with convergence insufficiency. Methods: A total of 235 elementary schoolchildren, 10.13 ± 2.45 years of age, were subjected to thorough eye examination ...

Oculomotor response in male collegiate pole vaulters after repeated head impact due to falls from heights: a pilot longitudinal study

open access: yesJournal of Physical Fitness and Sports Medicine, 2021
Subconcussive head impact exposure in sports is a complex public health issue. Although many head impacts are asymptomatic, the near point of convergence (NPC) that measures the closest point of focus before diplopia occurs, has been shown to reflect ...

Glauber dynamics of 2D Kac-Blume-Capel model and their stochastic PDE limits [PDF]

open access: yes, 2018
We study the Glauber dynamics of a two dimensional Blume-Capel model (or dilute Ising model) with Kac potential parametrized by $(\beta,\theta)$ - the "inverse temperature" and the "chemical potential".

Changes to Visual Parameters Following Virtual Reality Gameplay

open access: yesBritish and Irish Orthoptic Journal, 2022
Introduction: Virtual reality (VR) gameplay is popular with a range of games and educational resources available. However, it puts high demands on the visual system. Current evidence shows conflicting impacts on visual parameters.

Weighing the Cosmological Energy Contents with Weak Gravitational Lensing [PDF]

open access: yes, 1999
Bernardeau et al. (1997), using perturbation theory, showed that the skewness of the large-scale lensing-convergence, or projected mass density, could be used to constrain $\Omega_m$, the matter content of the universe.

The effect of acute ingestion of alcohol at 0.05% and 0.10% blood respiratory alcohol concentration on heterophoria

open access: yesAfrican Vision and Eye Health, 2016
Introduction: Alcohol ingestion has a significant effect on speech, vision and coordination. The legal limit for driving under the influence in South Africa is 0.05% blood alcohol concentration (BAC), whilst intoxication is considered to occur at 0.10 ...

Accommodative convergence–accommodation ratio and fusional capacity in patients with constant and intermittent exotropia

open access: yesJournal of Ophthalmology, 2021
Background: It has been reported that exotropia was seen in 16.9-23% of patients with strabismus. Exophoria and exotropia may be caused by congenital or acquired anomalies in orbital structure, ocular structure, or extraocular muscle attachment and/or ...

Ghost imaging using homodyne detection [PDF]

open access: yes, 2004
We present a theoretical study of ghost imaging based on correlated beams arising from parametric down-conversion, and which uses balanced homodyne detection to measure both the signal and idler fields.

Validity of ChPT -- is M_\pi=135 MeV small enough ? [PDF]

open access: yes, 2014
I discuss the practical convergence of the SU(2) ChPT series in the meson sector, based on 2+1 flavor lattice data by the Wuppertal-Budapest and Budapest-Marseille-Wuppertal collaborations.

Powers of ideals and convergence of Green functions with colliding poles

open access: yes, 2012
Let us have a family of ideals of holomorphic functions vanishing at N distinct points of a complex manifold, all tending to a single point. As is known, convergence of the ideals does not guarantee the convergence of the pluricomplex Green functions to ...
