Vision echo

One of the most frequently used methods in the speech disfluence therapy is the one based on the acoustical echo. A patient, who is a subject to therapy, hears his own voice with some delay and, thanks to that, his speech fluency increases. As it turned out a therapeutic effect can also be achieved by feedback of the speech with other human senses, such as touch or sight. The article presents a computer program that enables achieving the effect of the visional signal delay from camcorder on a monitor screen

Characterizing Exoplanets in the Visible and Infrared: A Spectrometer Concept for the EChO Space Mission

Transit-spectroscopy of exoplanets is one of the key observational techniques to characterize the extrasolar planet and its atmosphere. The observational challenges of these measurements require dedicated instrumentation and only the space environment allows an undisturbed access to earth-like atmospheric features such as water or carbon-dioxide. Therefore, several exoplanet-specific space missions are currently being studied. One of them is EChO, the Exoplanet Characterization Observatory, which is part of ESA's Cosmic Vision 2015-2025 program, and which is one of four candidates for the M3 launch slot in 2024. In this paper we present the results of our assessment study of the EChO spectrometer, the only science instrument onboard this spacecraft. The instrument is a multi-channel all-reflective dispersive spectrometer, covering the wavelength range from 400 nm to 16 microns simultaneously with a moderately low spectral resolution. We illustrate how the key technical challenge of the EChO mission - the high photometric stability - influences the choice of spectrometer concept and drives fundamentally the instrument design. First performance evaluations underline the fitness of the elaborated design solution for the needs of the EChO mission.Comment: 20 pages, 8 figures, accepted for publication in the Journal of Astronomical Instrumentatio

Pulmonary Embolism

There have been a number of approaches taken to image the pulmonary vasculature. This unit presents basic protocols based on black blood spin echo and/or gradient echo techniques for detection of pulmonary embolisms and deep vein thrombosis. Bright blood magnetic resonance angiography (MRA), 2‐D time‐of‐flight (TOF), and 3‐D contrast‐enhanced MRA is also presented for visualizing the entire vascular tree. The parameters provided in this unit are acquired from Siemens 1.5T Vision Scanner. These parameters may need to be altered depending on the field strength and equipment manufacturer.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145381/1/cpmia1301.pd

Sensory Compensation in Children Following Vision Loss after Trauma and Disease

Sensory compensation or sensory substitution occurs when a sense organ, such as the eye, is lost due to trauma or disease. Individuals often experience phantom limb sensation or pain but research increasingly points towards some individuals developing a heightened level of functioning in their remaining senses, particularly in their remaining intact eye. Losing an eye at an early age can often result in “super functioning” in the remaining eye providing that no similar trauma or disease results. Cases include young children who have undergone enucleation because of diagnosed unilateral retinoblastoma and whose remaining eye is free from disease

Size constancy in bat biosonar?

Perception and encoding of object size is an important feature of sensory systems. In the visual system object size is encoded by the visual angle (visual aperture) on the retina, but the aperture depends on the distance of the object. As object distance is not unambiguously encoded in the visual system, higher computational mechanisms are needed. This phenomenon is termed "size constancy". It is assumed to reflect an automatic re-scaling of visual aperture with perceived object distance. Recently, it was found that in echolocating bats, the 'sonar aperture', i.e., the range of angles from which sound is reflected from an object back to the bat, is unambiguously perceived and neurally encoded. Moreover, it is well known that object distance is accurately perceived and explicitly encoded in bat sonar. Here, we addressed size constancy in bat biosonar, recruiting virtual-object techniques. Bats of the species Phyllostomus discolor learned to discriminate two simple virtual objects that only differed in sonar aperture. Upon successful discrimination, test trials were randomly interspersed using virtual objects that differed in both aperture and distance. It was tested whether the bats spontaneously assigned absolute width information to these objects by combining distance and aperture. The results showed that while the isolated perceptual cues encoding object width, aperture, and distance were all perceptually well resolved by the bats, the animals did not assign absolute width information to the test objects. This lack of sonar size constancy may result from the bats relying on different modalities to extract size information at different distances. Alternatively, it is conceivable that familiarity with a behaviorally relevant, conspicuous object is required for sonar size constancy, as it has been argued for visual size constancy. Based on the current data, it appears that size constancy is not necessarily an essential feature of sonar perception in bats

Modern Narcissus: the lingering reflections of myth in modern art

Why has myth continued to fascinate modern artists, and why the myth of Narcissus, with its modern association with narcissism? This article considers the relationship between the Narcissus myth and the lineage of modern art that runs from Symbolism to surrealism through the polymorphous prism of the Greco-Roman Pantheon to which Narcissus belongs. The article offers an interpretation of the role of mythology in modern art that moves beyond psychoanalysis to incorporate the longer span of the art-historical tradition. Addressing issues of aesthetics, gender and sexuality, the following account highlights Narcissus‟s double nature as an erotic myth that comprises both identity formation and intersubjectivity, as enacted in the field of representation. The myths associated with Narcissus in the history of Western art will help us reconsider his role as a powerful figure capable to activate that slippage between word and image, identity and sociability, representation and reality which was celebrated by the Symbolists and formed the centre of the surrealists‟ social-aesthetic project
