Rank deficient Hankel matrices are at the core of several applications. However, in practice, coefficients these noisy due to e.g. measurements errors and computational errors, so generically involved full rank. This motivates problem structured low-rank approximation. Structured approximation problems, general, do not have a global efficient solution technique. In this paper we propose local o...

Reaction-diffusion systems have been primary tools for studying pattern formation. A skew-gradient system is well known to encompass a class of activator-inhibitor type reaction-diffusion that exhibit localized patterns such as fronts and pulses. While there substantial literature the case linear inhibitor equation, study nonlinear effect still limited. To fill this research gap, we investigate...

In depth cue-conflict conditions, various depth cues could represent different extents of depth. Previous studies have investigated the perceived size of negative afterimage in depth cue-correlated conditions in which different cues introduce almost the same amounts of depth to the visual system. This study examined the perceived size of the afterimage in the human observers in a condition that...
