In individual choices between alternatives x and y, the availability of a third alternative z, judged inferior to x but not to y, tends to increase preferences for x. Two experiments investigated corresponding strategic asymmetric dominance effects in games. In Experiment 1, 72 players chose strategies in six symmetric 3 · 3 games, each having one strategy dominating just one other, or in reduc...

Dairy cream is shown to be a simple, inexpensive, isotropic phantom useful for testing diffusional kurtosis imaging data acquisition and postprocessing. The MR-visible protons of cream exhibit slow and fast diffusion components, attributed to the fat and water protons, respectively, which give rise to a diffusion coefficient of 1.1 μm(2)/ms and a diffusional kurtosis of 1.2. These parameter val...

AMPUTATED LIMBS persist as "phantoms" in their owners' consciousness. Temporary or permanent severance of afferent pathways may also give rise to subjective experiences in which the position of the phantom limb is different from that of the real one. Attempts have been made to explain phantom phenomena as expressions of a "body image" or "body schema" subserving a preconscious neurophysiologica...

The Sussex Mk4 Electrical Impedance Mammography (EIM) system is a novel instrument, designed for the detection of early breast cancer, based upon Electrical Impedance Tomography (EIT). Many innovations in the field have been incorporated in the design improving both signal distribution and response. This paper investigates the behaviour of the contactless patient-electrode interface. The interf...

Most patients, post-amputation, report the experience of a phantom limb. Some even sense voluntary movements when viewing a mirror image of the intact limb superimposed onto the phantom limb. While delayed visual feedback of an action is known to reduce a sense of agency, the effect of delayed visual feedback on phantom motor sensation (i.e., sense of controlling a phantom limb) has not been ex...

A method for quantitative assessment of tree structures is reported allowing evaluation of airway or vascular tree morphology and its associated function. Our skeletonization and branch-point identification method provides a basis for tree quantification or tree matching, tree-branch diameter measurement in any orientation, and labeling individual branch segments. All main components of our met...

We report noninvasive detection of spin coherence in a collection Raman-driven cold atoms using dispersive Faraday rotation fluctuation measurements, which opens possibilities probing correlations quantum gases and other similar systems. demonstrate five orders magnitude enhancement the measured signal strength as compared to traditional noise spectroscopy with thermal equilibrium. Our observat...
