Accessory tone stimuli facilitate response performance despite being irrelevant for the current task. In order to investigate which processes are affected by accessory stimuli, we presented accessory tones in a simple response time (RT) task while varying the contingencies between accessory stimulation and either responses(Experiment 1) or stimulus conditions (Experiment 2). Accessory tones spe...

We propose a comprehensive theory for the morphological bounds on order-statistics filters (and their repeated iterations). Conditions are derived for morphological openings and closings to serve as bounds (lower and upper, respectively) on order-statistics filters (and their repeated iterations). Under various assumptions, morphological open-closings and close-openings are also shown to serve ...

We report a case of multiple fistulae in ano [8 external openings] in a 45-yrs-old man, who had a history of episodes of pain and pus discharge from openings around the anus since 4 years. Biopsy from the tract of one of the fistula confirmed tubercular infection. He underwent radiofrequency fistulotomy using a Ellman radiofrequency device along with anti-tubercular treatment, which resulted in...
