Unlike History, Should a Simulator Not Repeat Itself?

Does history repeat itself in medicine?

History repeats itself.

To the Editor: In a recent issue of Circulation, Zaman et al1 report a model for the preoperative risk stratification of patients at risk for developing atrial fibrillation (AF) after isolated coronary artery bypass grafting (CABG). They studied 326 patients prospectively and demonstrated that prolonged signal-averaged P-wave duration (SAPD), advanced age, and male sex identified patients at a ...

Type Theory Should Eat Itself

In this paper I present a partial formalisation of a normaliser for type theory in Agda[Nor07]; extending previous work on big-step normalisation[AC08,AC06]. The normaliser in written as an environment machine. Only the computational behaviour of the normaliser is presented omitting details of termination.

Does history repeat itself? Wavelets and the phylodynamics of influenza A.

Unprecedented global surveillance of viruses will result in massive sequence data sets that require new statistical methods. These data sets press the limits of Bayesian phylogenetics as the high-dimensional parameters that comprise a phylogenetic tree increase the already sizable computational burden of these techniques. This burden often results in partitioning the data set, for example, by g...

Garments fire: history repeats itself.

One hundred years after the Triangle Shirtwaist Factory fire in New York City that caused the death of 146 garment workers, a garment fire on November 24, 2012 in Bangladesh resulted in 111 deaths under remarkably similar circumstances. The majority of these workers were also young women, economically disadvantaged, migrants, and, by any definition, vulnerable. Fires have been a persistent prob...
