Selective decontamination: no oracle needed
We read with interest the study by Cuthbertson and colleagues [1] in a recent issue of Critical Care, and we appreciate their attempts to support studies regarding selective decontamination of the digestive tract (SDD). However, we have some concerns. The argument supporting a randomized controlled trial (RCT) for the evaluation of SDD is ambiguous. The Delphi method embraces ‘quasi-anonymity’,...
متن کاملNo adjustments are needed for multiple comparisons.
Adjustments for making multiple comparisons in large bodies of data are recommended to avoid rejecting the null hypothesis too readily. Unfortunately, reducing the type I error for null associations increases the type II error for those associations that are not null. The theoretical basis for advocating a routine adjustment for multiple comparisons is the "universal null hypothesis" that "chan...
متن کاملNo disk needed around HD 199143
We present new, high angular resolution images of HD 199143 in the Capricornus association, obtained with the adaptive optics system ADONIS+SHARPII at the ESO 3.6m Telescope of La Silla Observatory. HD 199143 and its neighbour star HD 358623 (separation ∼ 5 ′ away) have previously been imaged with adaptive optics. For each star, a companion has been detected in the J and K bands at respective s...

متن کاملAC-Superposition with Constraints: No AC-Unifiers Needed
We prove the completeness of (basic) deduction strategies with constrained clauses modulo associativity and commutativity (AC). Here each inference generates one single conclusion with an additional equality s = AC t in its constraint (instead of one conclusion for each minimal AC-uniier, i.e. exponentially many). Furthermore, computing AC-uniiers is not needed at all. A clause C T ] ] is redun...
