all societies face the need to make judgments about what interventions (both public health and personal medical) to provide to their populations under reasonable resource constraints. their decisions should be informed by good evidence and arguments from health technology assessment (hta). but if hta restricts itself to evaluations of safety, efficacy, and cost-effectiveness, it risks being vie...

This paper analyses two front-end receiver architectures intended for GSM900 use; (i) A direct-conversion receiver, and (ii) a low-IF receiver using a poly-phase filter. The aim is to determine the circuit performance required for GSM operation and to compare this to current state-of-the-art CMOS performance. The analysis shows that direct-conversion receivers fail to meet specifications when b...

In this paper, the authors propose a simple model of cell motility inspired by the plasmodium of Physarum polycephalum. The model focuses on the “softness” of aggregations of protoplasm. The model has only two parameters, yet generates a variety of final states, as well as the morphological changes of Physarum according to the condition of the culture medium.

Use of Bayesian models to explain both highand lowlevel aspects of cognitive function promises better connections between cognitive science and cognitive neuroscience. But standing in the way are fundamental problems, such as the computational intractability of Bayesian inference, and the general difficulty of understanding how Bayesian calculation can deal with structural representation. Getti...
