A study was carried out of monocular disc photographs from 33 eyes for which the visual fields on both static profile and kinetic perimetry has been performed. Physical signs looked for at the optic disc included thinning of the neuroretinal rim, angulation of retinal vessels, extension of laminar dots, undercutting of the neuroretinal rim, and absence and pallor of the neuroretinal rim. These ...

Objective To examine whether or not an edrophonium challenge test is useful for diagnosing cervical dystonia. Patients We evaluated 10 patients with cervical dystonia and 10 with hemifacial spasms (disease controls). We administered edrophonium and saline in this double-blinded study. Before and after the injection, we recorded the participants' clinical signs using a video camera to assess the...

UNLABELLED Pattern recognition is a key tool that enables radiologists to evoke certain diagnoses based on a radiologic appearance. In Shakespeare's Hamlet, Polonius tells his son Laertes to dress well because "apparel oft proclaims the man"; this phrase is now expressed in modern parlance as "the clothes maketh the man". Similarly in radiology, appearances are everything, and in the case of ra...

Through the research on application of regional cultural symbols in logo design local museums, this paper summarizes general methods museums. and analysis existing literature cases related to Museum signs, based Saussure's "signifier" semiotics, relationship between signs is analyzed, problems development construction refining visual are studied, And then innovative with characteristics.

THE ophthalmoscopic appearances of hereditary degenerative macular lesions vary greatly, as do the functional disturbances produced, the time of onset, the course, and the mode of inheritance. Behr (1920), finding the time of onset fairly constant in the members of one sibship, classified hereditary macular degeneration on this basis, starting with the congenital cases (Best, 1905), proceeding ...

Multiple system atrophy (MSA) is a rare movement disorder and a member of the 'parkinsonian syndromes', which also include Parkinson's disease (PD), progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB) and corticobasal degeneration (CBD). Multiple system atrophy is a complex syndrome, in which patients exhibit a variety of signs and symptoms, including parkinsonism, ataxia and ...

We tested hearing 6- and 10-month-olds' ability to discriminate among three American Sign Language (ASL) parameters (location, handshape, and movement) as well as a grammatical marker (facial expression). ASL-naïve infants were habituated to a signer articulating a two-handed symmetrical sign in neutral space. During test, infants viewed novel two-handed signs that varied in only one parameter ...

Dementia with Lewy bodies ('Lewy body dementia' or 'diffuse Lewy body disease') (DLB) is the second most common form of dementia to affect elderly people, after Alzheimer's disease. A combination of the clinical symptoms of Alzheimer's disease and Parkinson's disease is present in DLB and the disorder is classified as a 'parkinsonian syndrome', a group of diseases which also includes Parkinson'...

Advanced Driver Assistance Systems are used to increase the security of vehicles. Computer Vision is one of the main technologies used for this aim. Lane marks recognition, pedestrian detection, driver drowsiness or road sign detection and recognition are examples of these systems. The last one is the goal of this paper. A system that can detect and recognize road signs based on color and shape...

Word recognition in spoken language is known to be a dynamic, incremental, and continuous process. As words unfold in time, listeners activate a range of potential lexical candidates, including those that share semantic (Yee & Sedivy, 2006) and phonological (Allopenna, Magnuson, & Tanenhaus, 1998) features with the target word. Among the methodological techniques used to probe real-time recogni...
