We consider the general problem of comparing and integrating computational models of cardiac tissue at different levels of physiological detail. We use a general theory of synchronous concurrent algorithms to model spatially extended biological systems, and expand the theory to create hierarchical models by relating observable behaviour at different levels. The general concepts and methods are ...

MOTIVATION The construction of statistics for summarizing posterior samples returned by a Bayesian phylogenetic study has so far been hindered by the poor geometric insights available into the space of phylogenetic trees, and ad hoc methods such as the derivation of a consensus tree makeup for the ill-definition of the usual concepts of posterior mean, while bootstrap methods mitigate the absen...

[1] 64 climate reconstructions, based on regression of temperature fields on multi-proxies and mutually distinguished by at least one of six standard criteria, cover an entire spread of millennial histories. No single criterion is accountable for the spread, which appears to depend on a complicated interplay of the criteria. The uncertainty is traced back to the fact that regression is applied ...
