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 کاملAn Energetic Afterglow from a Distant Stellar Explosion
We present the discovery of radio afterglow emission from the high redshift (z = 6.295) burst GRB050904. The peak flux density for this burst is similar to typical low-redshift gamma-ray bursts (GRB). We further show that beyond a redshift of order unity, the flux density of radio afterglows are largely insensitive to redshift, consistent with predictions. By combining the existing X-ray, near-...
متن کاملGravitational Waves from Stellar Collapse: Correlations to Explosion Asymmetries
The collapse of massive stars not only produces observable outbursts across the entire electromagnetic spectrum but, for Galactic (or near-Galactic) supernovae, detectable signals for ground-based neutrino and gravitational wave detectors. Gravitational waves and neutrinos provide the only means to study the actual engine behind the optical outbursts: the collapsed stellar core. While the neutr...
متن کاملPolar spots and stellar spindown: is dynamo saturation needed?
Dynamosaturation is often invokedwhen calculating the rotational evolution of cool stars. At rapid rotation rates a saturated dynamo reduces the angular momentum carried away by the stellar wind. This, in turn, may explain the high rotation rates present in the distribution of rotation periods in young clusters. Here we point out that concentration of magnetic flux near the poles of rapidly rot...
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...
