Myotragus balearicus (Artiodactyla, Caprinae) is an extinct caprine endemic of the Eastern Balearic Islands or Gymnesics (i.e., Mallorca, Menorca and surrounding islets, Western Mediterranean Sea). In spite of its small size, c. 50cm height at the shoulder, it was the largest mammal inhabiting these islands until the human arrival, and it had peculiar short legs and frontal vision. It disappeared between 2830 and 2210calBCE. The coprolites here studied were recovered from Cova Estreta, in Pollença, Mallorca...

OBJECTIVE: This study explores comparative differentials in health care needs, health care utilization, and health status between Medicaid and private/employer-sponsored insurance (ESI) among a statewide population of children with special health care needs (CSHCN) in Ohio. METHODS: We used data from the 2012 Ohio Medicaid Assessment Survey to examine CSHCN's health care needs, utilization, status, and health outcomes by insurance type. Adjusted multivariable logistic regression models were used to explore associations between public and private health insurance, as well as the utilization and health outcome variables...

Ignacio Serrano-Pedraza, Kathleen Vancleef, Jenny C A Read
New forms of stereoscopic 3-D technology offer vision scientists new opportunities for research, but also come with distinct problems. Here we consider autostereo displays where the two eyes' images are spatially interleaved in alternating columns of pixels and no glasses or special optics are required. Column-interleaved displays produce an excellent stereoscopic effect, but subtle changes in the angle of view can increase cross talk or even interchange the left and right eyes' images. This creates several challenges to the presentation of cyclopean stereograms (containing structure which is only detectable by binocular vision)...

Visual capture and the ventriloquism aftereffect resolve spatial disparities of incongruent auditory visual (AV) objects by shifting auditory spatial perception to align with vision. Here, we demonstrated the distinct temporal characteristics of visual capture and the ventriloquism aftereffect in response to brief AV disparities. In a set of experiments, subjects localized either the auditory component of AV targets (A within AV) or a second sound presented at varying delays (1-20 s) after AV exposure (A2 after AV)...

Optokinetic nystagmus (OKN) is an involuntary eye movement responsible for stabilizing retinal images in the presence of relative motion between an observer and the environment. Fully understanding the development of OKN requires a neurally plausible computational model that accounts for the neural development and the behavior. To date, work in this area has been limited. We propose a neurally plausible framework for the joint development of disparity and motion tuning in the visual cortex and of optokinetic and vergence eye-movement behavior...

Vision typically has better spatial accuracy and precision than audition and as a result often captures auditory spatial perception when visual and auditory cues are presented together. One determinant of visual capture is the amount of spatial disparity between auditory and visual cues: when disparity is small, visual capture is likely to occur, and when disparity is large, visual capture is unlikely. Previous experiments have used two methods to probe how visual capture varies with spatial disparity. First, congruence judgment assesses perceived unity between cues by having subjects report whether or not auditory and visual targets came from the same location...

Purpose: Single vision occurs through a combination of fusion and suppression. When neither mechanism takes place, we experience diplopia. Under normal viewing conditions, the perceptual state depends on the spatial scale and interocular disparity. The purpose of this study was to examine the three perceptual states in human participants with normal and amblyopic vision. Methods: Participants viewed two dichoptically separated horizontal blurred edges with an opposite tilt (2...

Although a 0.3 Bangerter filter, which reduces visual acuity, is frequently used for treating moderate amblyopia, the effects on gross stereopsis are not well known. This study quantitatively evaluated whether gross stereopsis is degraded by a Bangerter filter. Seven healthy subjects (median age: 29 years) participated in this psychophysical study. Targets with crossed disparities of 1°, 2°, 3°, 4°, and 5° were randomly presented on a three-dimensional television display. The subjects indicated the point at which the targets popped out from the television screen (matching method)...

: Similar to the trend worldwide, hypertension (HTN) is also the single most attributable cause for mortality in South-East Asia (SEA). But while in developed regions, the prevalence of HTN appears to be stabilizing or decreasing, the rates in SEA continue to rise. Around a third of the adult population in SEA have elevated blood pressure (BP) with nearly 1.5 million deaths (9.4% of total deaths) attributable to HTN annually.In several countries in SEA, awareness level of HTN is less than 50% but in the more affluent countries in the region, awareness ranges from 56% to 70%...

The prevalence of diagnosed human immunodeficiency virus (HIV) infection in Hispanics/Latinos in the United States is more than twice as high as the prevalence among non-Hispanic whites (1). Services that support retention in HIV medical care and assist with day-to-day living, referred to here as ancillary services, help persons living with HIV access HIV medical care, adhere to HIV treatment, and attain HIV viral suppression. The needs for these ancillary services among Hispanics/Latinos are not well described (2)...

The well established disparities in health outcomes between Indigenous and non-Indigenous Australians include a significant and concerning higher incidence of preterm birth, low birth weight and newborn mortality. Chronic diseases (eg, diabetes, hypertension, cardiovascular and renal disease) that are prevalent in Indigenous Australian adults have their genesis in utero and in early life. Applying interventions during pregnancy and early life that aim to improve maternal and infant health is likely to have long lasting consequences, as recognised by Australia's National Maternity Services Plan (NMSP), which set out a 5-year vision for 2010-2015 that was endorsed by all governments (federal and state and territory)...

Does human vision show the contrast invariance expected of an ideal stereoscopic system for computing depth from disparity? We used random-dot stereograms to investigate the luminance contrast effect on perceived depth from disparity. The perceived depth of disparity corrugations was measured by adjusting the length of a horizontal line to match the perceived depth of the corrugations at various luminance contrasts. At each contrast, the perceived depth increased with disparity up to a critical value, decreasing with further increases in disparity...

BACKGROUND: Areas near parks may present active travelers with higher risks than in other areas due to the confluence of more pedestrians and bicyclists, younger travelers, and the potential for increased traffic volumes. These risks may be amplified in low-income and minority neighborhoods due to generally higher rates of active travel or lack of safety infrastructure. This paper examines active travel crashes near parks and builds on existing research around disparities in park access and extends research from the Safe Routes to School and Safe Routes to Transit movements to parks...

The SLC4A11 gene encodes the bicarbonate-transporter-related protein BTR1, which is mutated in syndromes characterized by vision and hearing loss. Signs of these diseases (congenital hereditary endothelial dystrophy (CHED) and Harboyan Syndrome) are evident in mouse models of Slc4a11 disruption. However, the intrinsic activity of Slc4a11 remains controversial, complicating assignment of its (patho)physiological role. Most studies concur that Slc4a11 transports H(+) (or the thermodynamically equivalent species OH(-)) rather than HCO3 (-) but disparities have arisen as to whether the transport is coupled to another species such as Na(+) or NH3/NH4 (+) Here for the first time, we examine the action of mouse Slc4a11 in Xenopus oocytes...

PURPOSE: Visual impairment presents significant risks for occupational injuries among farmworkers, a vulnerable population with limited access to vision care. Although previous research has noted farmworkers' low lifetime experience with vision screening and high rates of complaints of eye ailments and poor vision, there have been few screening data collected to evaluate these self-reports. The objectives of this analysis are to (1) describe farmworker visual health using standardized visual acuity screening data and self-reported visual function, and (2) to compare the screening and self-report data...

Stereo matching is essential and fundamental in computer vision tasks. In this paper, a novel stereo matching algorithm based on disparity propagation using edge-aware filtering is proposed. By extracting disparity subsets for reliable points and customizing the cost volume, the initial disparity map is refined through filtering-based disparity propagation. Then, an edge-aware filter with low computational complexity is adopted to formulate the cost column, which makes the proposed method independent on the local window size...
