Surgical timing for ectopia lentis has not been well described until now. The purpose of this study is to find a benchmark as to how far observation would be allowed in children with ectopia lentis when they and their families are reluctant to go through surgery. Retrospective review was made on 15 consecutive patients (14 children and one adult) with ectopia lentis in both eyes, seen at a refe...

We present the concept of the topological symmetry group as a way to analyze the symmetries of non-rigid molecules. Then we characterize all of the groups which can occur as the topological symmetry group of an embedding of a complete graph of the form K4r+3 in S3. 1. Topological symmetry groups. Knowing the symmetries of a molecule helps to predict its chemical behavior. But, what exactly do w...

Methods: A randomized clinical trial was performed to evaluate the anatomic and visual benefits of FTMH surgery for lesions of 9 months or less symptom duration and visual acuity of 20/60 or less. We compared surgery with natural history and determined whether use of intraoperative adjunctive autologous serum improves the surgical outcome. Eyes were randomized to (1) observation, (2) vitrectomy...

Take Home Messages-Automated activity monitoring systems (AAM) can be incorporated as a tool to replace visual observation of estrus.-General considerations before an AAM system acquisition include: current estrus detection (ED) efficiency, system cost, visual observations cost, and system life expectancy. Purchasing a system with a life expectancy of at least 5 years would be critical under al...

In this paper, we present an architecture for software agents that enables them to learn vocabulary through the observation of each other bodies and actions. Besides sensors, effectors, and action control, the architecture provides the equivalent of a body with visual appearance. The agent soft visual appearance is designed to be seen by other software agents, not by people. The paper describes...

PURPOSE To evaluate the effect of intravitreal bevacizumab injection (IVBI) in acute central serous chorioretinopathy (CSC) patients. METHODS Patients with acute CSC received IVBI (1.25 mg/0.05 mL) or observation by randomization. Twelve eyes in each group completed 6 months of regular follow-up and were ultimately included in this study. Each patient was assessed using best corrected visual ...

Project Description: The proposal aims at developing a software service interface for natural-like interaction of humans with PR2-type personal robots. Natural-like interaction will be considered for communication (a model of hand gestures will be established that allow many natural gestures to be interpreted by the personal robot) and emulation of human skills, routine tasks (extracting reusab...

PURPOSE To evaluate the efficacy of anti-vascular endothelial growth factor (VEGF) compared with observation for treating acute central serous chorioretinopathy (CSC). METHODS A retrospective study of 36 patients with acute CSC, including 21 patients treated with anti-VEGF (anti-VEGF group) and 15 patients with observation (observation group). Patients in the anti-VEGF group received a single...

Conventional methodology for examining conditioned fear has involved visual-based technologies such as cameras and direct observation. These methods are excellent screening tools of fear behavior (i.e. freezing). However, they do not provide a physiological output, which could be useful to examine neurophysiological correlates of fear. We found that dorsal neck electromyography can be used as a...

Learning by observation is an important goal in developing complete intelligent robots that learn interactively. We present a visual analogy approach toward an integrated, intelligent system capable of learning skills from observation. In particular, we focus on the task of retrieving a previously acquired case similar to a new, observed skill. We describe three approaches to case retrieval: fe...
