PURPOSE The latency of adaptation of the human vergence system to a change in convergence or divergence forced upon it by a prism was investigated in this pilot study. METHODS Adaptation was stimulated by a 5-s period of binocular vision through a prism of 0 delta, -8 delta, or 8 delta. Immediately thereafter and for a further period of 45 s, lateral heterophoria was monitored subjectively by...

Previous research has suggested that infants are unable to make a corrective eye movement in response to a small base-out prism placed in front of one eye before 14-16 weeks [1]. Three hypotheses have been proposed to explain this early inability, and each of these makes different predictions for the time of onset of a response to a larger prism. The first proposes that infants have a 'degraded...

This paper presents a tunable optofluidic prism based on the configuration of two laminar flow streams with different refractive indices in a triangular chamber. The chambers with 70° and 90° apex angles are designed based on simulation results, which provide the optimum working range and avoid recirculating flows in the chambers. In addition, a hydrodynamic model has been developed to predict ...

PURPOSE Horizontal peripheral prisms for hemianopia provide field expansion above and below the horizontal meridian; however, there is a vertical gap leaving the central area (important for driving) without expansion. In the oblique design, tilting the bases of both prism segments toward the horizontal meridian moves the field expansion area vertically and centrally (closing the central gap) wh...

purpose: to evaluate the effect of limited dissection of tenon sheath on the outcome of horizontal strabismus surgery. methods: patients with horizontal strabismus, aged between six and 50 years, were enrolled in this non-randomized study. patients with pattern and vertical strabismus or a history of strabismus surgery were excluded. the strabismus surgeries consisted of bimedial recession (bmr...

BACKGROUND Our goal is to improve the safety and effectiveness of inpatient care. Rather than focus on improving process of care, we focus on the social structure within physician teams. We have developed the Physician Relationships, Improvising, and Sensemaking (PRISm) intervention to improve the way physician teams round, enabling them to better relate, make sense of their patients' condition...

Previous research has shown that prism adaptation (prism adaptation) can ameliorate several symptoms of spatial neglect after right-hemisphere damage. But the mechanisms behind this remain unclear. Recently we reported that prisms may increase leftward awareness for neglect in a task using chimeric visual objects, despite apparently not affecting awareness in a task using chimeric emotional fac...

Preface The past few years have witnessed a tremendous interest in logic-based probabilistic learning as testified by the number of formalisms and systems and their applications. Logic-based probabilistic learning is a multidisciplinary research area that integrates relational or logic formalisms, probabilistic reasoning mechanisms, and machine learning and data mining principles. Logic-based p...

In this paper we describe our experience with model checking randomized distributed algorithms using PRISM, a symbolic model checker for concurrent probabilistic systems currently being developed. PRISM uses Multi-Terminal Binary Decision Diagrams (MTBDDs) as supplied by the CUDD package of Fabio Somenzi. Implemented in Java, PRISM has a system description language similar to Reactive Modules a...
