Approximately 1 in 6 conventional, transvenous pacemaker patients experience complications the first 3 years of implant. The Aveir™ VR (Abbott, Abbott Park, IL) is a newly released, single-chamber, ventricular leadless (LP), featuring helix-based fixation mechanism and pre-fixation exploratory electrical mapping capability. By eliminating lead subcutaneous pocket, this alternative to pacemakers...

Despite evidence indicating fatness and thinness information are processed differently among weight-preoccupied and eating disordered individuals, the exact nature of these attentional biases is not clear. In this research, eye movement (EM) tracking assessed biases in specific component processes of visual attention (i.e., orientation, detection, maintenance and disengagement of gaze) in relat...

This paper employs Fisher’s model of adaptation to understand the expected fitness effect of fixing a mutation in a natural population. Fisher’s model in one dimension admits a closed form solution for this expected fitness effect. A combination of different parameters, including the distribution of mutation lengths, population sizes, and the initial state that the population is in, are examine...

PURPOSE To identify factors that influence the outcome of treatment for unilateral amblyopia, as a part of the Monitored Occlusion Treatment of Amblyopia Study (MOTAS). METHODS This was an intervention study consisting of three nonoverlapping phases: "Baseline", "refractive adaptation" (18 weeks of full-time spectacle wear), and "occlusion" (6 hours of patching per day, objectively monitored)...

BACKGROUND There have been rare cases of traumatic cervical spondyloptosis without neurological compromise. We report another case and provide a review of the literature, with a focus on appropriate management. CASE DESCRIPTION A 60-year-old male rode his bicycle into a stationary semi-truck. He reported initial bilateral upper extremity paresthesias that resolved. Imaging demonstrated C7 on ...

Three experiments were conducted that compared the eye movement pattern to a peripheral word or letter string as a function of the position of an initial fixation stimulus relative to the center of the screen and the straight-ahead position. Results revealed a strong bias of the eye behavior towards the center of the screen, but not towards the straight-ahead position. Saccades were greater in ...

The relation between parafoveal letter and space information in eye movement guidance during reading was investigated in 2 experiments. Contingent upon the reader's fixation, the type of parafoveal information available to the right of fixation was varied by (a) space information only, (b) space information with letter information added at some delay, or (c) letter and space information simulta...
