Response to loomis et al

air pollution as a predictor of mortality in a prospective study of US adults. Response to Loomis et al. I would like to address comments of Loomis et al. about inferences drawn from studies using group-level exposure variables , the use of the tobacco analogy, the application of Hill's criteria for causality (1), and the use of the Hertz-Picciotto criteria for evaluating studies (2). Whether t...

Reply to Hutchison and Loomis

the perceived distance to a target is influenced by the effort required to walk to its location. Hutchison and Loomis (H&L) reported an experiment that failed to find a significant influence of effort on indices of apparent distance. There were numerous important differences between the design and methods of H&L’s study and those of Proffitt et al. Moreover, there are important theoretical reas...

Wheeler Graphs: Variations on a Theme by Burrows and Wheeler

The famous Burrows-Wheeler Transform was originally defined for single strings but variations have been developed for sets of strings, labelled trees, de Bruijn graphs, alignments, etc. In this talk we propose a unifying view that includes many of these variations and that we hope will simplify the search for more. Somewhat surprisingly we get our unifying view by considering the Nondeterminist...

The Loomis–Sikorski Theorem for EMV -algebras

Recently, in [DvZa], we have introduced EMV -algebras which resemble MV -algebras but the top element is not guaranteed for them. For σ-complete EMV -algebras, we prove an analogue of the Loomis–Sikorski Theorem showing that every σ-complete EMV -algebra is a σ-homomorphic image of an EMV -tribe of fuzzy sets where all algebraic operations are defined by points. To prove it, some topological pr...
