CellML 1.1 modularity

CellML 1.1 is an open XML-based language designed to store and exchange computer-based mathematical models. It has a simple facility to import existing models in order to create new models. The import facility encourages the development of hierarchical models and model reuse through the creation of well-curated model components in public model repositories. This presentation describes some of the features of CellML 1.1 and best practices for taking advantage of these features

Rational planning and politicians' attitudes to spending and reform: replication and extension of a survey experiment

The rational planning cycle of formulating strategic goals and using performance information to assess implementation is assumed to assist decision-making by politicians. Empirical evidence for this assumption is, however, scarce. Our study replicates Nielsen and Baekgaard’s (2015) experiment on the relation between performance information and politicians’ attitudes to spending and reform and extends this experiment by investigating the role of strategic goals. Based on a randomized survey experiment with 1.484 Flemish city councilors and an analysis of 225 municipal strategic plans, we found that information on low and high performance as well as strategic goals directly impact decision-making by politicians

Quantum state reconstruction via continuous measurement

We present a new procedure for quantum state reconstruction based on weak continuous measurement of an ensemble average. By applying controlled evolution to the initial state new information is continually mapped onto the measured observable. A Bayesian filter is then used to update the state-estimate in accordance with the measurement record. This generalizes the standard paradigm for quantum tomography based on strong, destructive measurements on separate ensembles. This approach to state estimation can be non-destructive and real-time, giving information about observables whose evolution cannot be described classically, opening the door to new types of quantum feedback control.Comment: 4 pages, 2 figure
