Ubiquitous computing requires lightweight approaches to coordinating tasks distributed across smart devices. We are currently developing a semantic workflow modelling approach that blends the proven robustness of XPDL with semantics to support proactive behaviour. We illustrate the potential of the model through an example based on mixing a dry martini.

If the phase transition from quark matter to hadron gas is first order, matter at the appropriate temperatures and densities can exist as a mixed phase consisting of plasma droplets in equilibrium with a surrounding hadronic fluid. If formed in ion collisions, this mixed phase can produce large event-by-event fluctuations as the system hadronizes. Extraordinary baryon fluctuations [1] can accom...

Muscles are ideal models with which to examine the relationship between structure and metabolism because they are some of the most highly structured cells, and are capable of the largest and most rapid metabolic transitions as well as the highest metabolic rates known. Studies of metabolism have traditionally been conducted within what can considered as the kinetic paradigm provided by 'solutio...
