In this paper, we develop a constant amortized time (CAT) algorithm for generating permutations with a fixed number of excedances. We obtain a Gray code for permutations having one excedance. We also give a bijection between the set of n-length permutations with exactly one excedance and the set Sn(321, 2413, 3412, 21534)\{123 . . . (n− 1)n}. This induces a Gray code for the set Sn(321, 2413, 3...

Abstract Background Differences in one-year outcomes among early compared to delayed responders vedolizumab have been demonstrated ulcerative colitis. However, it is unclear whether differences exist with ustekinumab, and what factors differentiate from non-responders. Methods This was a post-hoc analysis of patient-level data the UNIFI clinical trial. Ustekinumab-treated patients response, def...

BACKGROUND The European Union prohibits the use of chloramphenicol (CAP) as a veterinary drug in food-producing animals. Nevertheless, CAP have been detected in milk products (liquid milk and milk powder). Therefore, it is necessary to develop sensitive methods for determining CAP residues in milk powder. OBJECTIVE The aim of this study was to develop and validate a confirmatory method for de...
