White-Nose Syndrome (WNS) is an epizootic disease in hibernating bats caused by the fungus Pseudogymnoascus destructans. Surveillance for P. destructans at bat hibernacula consists primarily of visual surveys of bats, collection of potentially infected bats, and submission of these bats for laboratory testing. Cryptic infections (bats that are infected but display no visual signs of fungus) cou...

Retrobulbar hemorrhage is a rare complication that may occur after mid-face injuries or following soft and hard tissue surgery around the eyes. The cardinal signs and symptoms of retrobulbar hemorrhage are pain, diplopia, ophthalmoplegia, a progression of increasing proptosis, and decreasing visual acuity leading to blindness. The diagnosis can be confirmed with computed tomography (CT) of the ...

A 50-year-old female patient with visual disturbances was referred for further evaluation of a heart murmur. Fundoscopy revealed a Roth spot in both eyes. A physical examination showed peripheral signs of infective endocarditis, including Osler nodes, Janeway lesions, and splinter hemorrhages. Our preoperative diagnosis was subacute bacterial endocarditis with severe aortic regurgitation. The p...

This paper describes a model for the emergence of a visual communication language in a team of robot football. The method is based on using visual stimuli for the transmission of information between players. In order to represent visual stimuli and their meanings, the paper presents visual signs as an abstract and grounded representation. The model and methods presented here are experimentally ...

Animals and humans share an evolutionary ancient quantity representation which is characterized by analog magnitude features: Discriminating magnitudes becomes more difficult with increasing set sizes (size effect) and with decreasing distance between two numerosities (distance effect). Humans show these effects even with number symbols. We wondered whether monkeys would show the same psychophy...

Sign language is a visual language used by deaf people. One difficulty of sign language recognition is that sign instances of vary in both motion and shape in three-dimensional (3D) space. In this research, we use 3D depth information from hand motions, generated from Microsoft's Kinect sensor and apply a hierarchical conditional random field (CRF) that recognizes hand signs from the hand motio...

UNLABELLED Pituitary apoplexy is a rare event in pregnancy. A 41-year-old woman with a known pituitary microadenoma presented with visual disturbance and headache during the second trimester of pregnancy. Magnetic resonance imaging (MRI) demonstrated pituitary apoplexy with chiasmal compression. After treatment with corticosteroid therapy, she underwent transsphenoidal excision of the pituitary...

Two early studies showed that visual prompts can be effectively used to encourage people to turn off the lights in unoccupied classrooms, but they were methodologically limited. The current study used an ABAB-B design with an 11-week follow-up to investigate whether two different visual prompts (large and small signs) could be employed to increase "lights off" behaviour in 17 unoccupied washroo...
