Blind source separation and blind output decorrelation are two well-known problems in signal processing. For instantaneous mixtures, blind source separation is equivalent to a generalized eigen-decomposition, while blind output decorrelation can be considered as an iterative method of output orthogonalization. We propose a steepest descent procedure on a new cost function based on the Frobenius...

OBJECTIVES To analyse the effect of women's characteristics on their willingness to join a blind or a non-blind subtrial or to be excluded by physicians. DESIGN Primary prevention trial of postmenopausal hormone therapy (HT). A 2×2, randomised design with a non-blind HT arm or control arm and a blind HT arm or placebo arm. SETTING 3 clinical centres in Estonia. METHODS Interest in joining...

Blindfolded sighted, congenitally blind, late-blind, and very-low-vision subjects were tested on a tangible version of the embedded-figures test. The results of ANOVAs on accuracy measures yielded superior performance by the very-low-vision and late-blind subjects compared with the blindfolded sighted and congenitally blind participants. Accuracy of the congenitally blind subjects was similar t...

This literature review examines social science research on blind women’s experiences with sexual relationships. The findings suggest that socially constructed barriers marginalize blind women, often resulting in blind women being labeled as asexual. The intersection of able-ism and sexism positions many blind women as outsiders who do not possess sexual attractiveness. After discussing perspect...

There is an error in the antepenultimate sentence of the abstract. The number of treatments is incorrect. The correct sentence is: The control scenario requires community-directed treatment with ivermectin beyond 2045 with around 2.63 billion treatments over 2013–2045; the elimination scenario, until 2028 in areas where feasible, but beyond 2045 in countries with operational challenges, around ...

Observers have difficulty detecting visual changes. However, they are unaware of this inability, suggesting that people do not have an accurate understanding of visual processes. We explored whether this error is related to participants' beliefs about the roles of intention and scene complexity in detecting changes. In Experiment 1 participants had a higher failure rate for detecting changes in...
