The present study examined how the availability of and alterations in sensory information during the sensory organization test (SOT) influenced the amount, variability, and temporal structure of spontaneous postural sway in young, healthy adults. Findings indicated that postural sway tended to increase in amount and variability as the SOT condition became(More)
The authors investigated the multisensory control of posture by altering sensory information across the visual and somatosensory systems. The support surface and visual surround were sway-referenced to anterior/posterior center of mass sway and the gain between postural sway and degree of sway referencing was manipulated (gain settings were 0.2, 1.0, and(More)
Quantum computations that involve only Clifford operations are classically simulable despite the fact that they generate highly entangled states; this is the content of the Gottesman-Knill theorem. Here we isolate the ingredients of the theorem and provide generalisations of some of them with the aim of identifying new classes of simulable quantum(More)
Condition-dependence theory predicts that sexual selection will facilitate adaptation by selecting against deleterious mutations that affect the expression of sexually selected traits indirectly via condition. Recent empirical studies have provided support for this prediction; however, their results do not elucidate the relative effects of pre- and(More)
<i>ColourNet</i> is a digital art system composed of a set interactive and interacting artworks. Although the artworks are able to work independently, they can also operate together to provide enhanced possibilities for human interaction and creative participation. We describe the <i>ColourNet</i> digital art system and demonstrate how people can interact(More)
Veterans are a significant subpopulation in criminal justice populations, comprising between 9% and 10% of arrestee, jail, prison, and community-supervision populations. In order to address the needs of justice-involved veterans, the U.S. Department of Veterans Affairs (VA) Veterans Justice Programs (VJP) offer services to veterans at multiple points in(More)
Structural theorems regarding linear preservers of the higher rank numerical ranges are proved for the real linear space of bounded selfadjoint operators or the complex linear space of bounded linear operators acting on a Hilbert space. It is shown that the linear preservers of rank k-numerical ranges must be of the standard form: unitary similarity or(More)
