We present a radial-velocity study of the triple-lined system Gliese 644 and derive spectroscopic elements for the inner and outer orbits with periods of 2.9655 and 627 days. We also utilize old visual data, as well as modern speckle and adaptive optics observations, to derive a new astrometric solution for the outer orbit. These two orbits together allow us to derive masses for each of the thr...

The first cycle our closed loop audit aimed assess safety VTE prescribing in at a district general hospital. current aims evaluate guideline compliance following interventions.

Stock price fluctuations result from interactions between economic agents. Modelling the financial world as a complex self-organizing system is thus natural. To keep tractability, obtain theoretical results and develop our intuition about complexity economics, we have constructed a very simple artificial stock market. Despite its necessary over-simplification, our model is rich enough to offer ...
