Sponsored trials do not necessarily give more-favourable results

Not Necessarily More Switches More Routability

It has been observed experimentally that the mapping of global to detailed routing in conventional FPGA routing architecture (2D array) yields unpredictable results. In [8,10,13], a different class of FPGA structures called Greedy Routing Architectures (GRAs), where a locally optimal switch box routing can be extended to an optimal entire chip routing, were investigated. It was shown that GRAs ...

DESIGN Prospective cohort study from February 2009 to October 2009. SETTING Eleven teaching hospitals. PARTICIPANTS HCWs. METHODS One thousand thirteen observations conducted on HCWs. Additional data included the number...

Do multilevel models ever give different results?

It is sometimes said that the use of multilevel models over OLS regression makes no substantive difference to interpretation and represents something of a fuss over nothing. This short paper demonstrates with a simple example that this is not always the case.
