Shannon entropy is often considered as a measure of uncertainty. It is commonly believed that entropy is a good measure of how many guesses it will take to correctly guess a single value generated by a source. This belief is not well founded. We summarise some work in this area, explore how this belief may have arisen via the asymptotic equipartition(More)
There is unmet need in patients suffering from chronic pain, yet innovation may be impeded by the difficulty of justifying economic value in a field beset by data limitations and methodological variability. A systematic review was conducted to identify and summarise the key areas of variability and limitations in modelling approaches in the economic(More)
Future space missions require high-performance on-board processing capabilities and a high degree of flexibility. State of the art radiation tolerant SRAM-based FPGAs with large gate count provide an attractive solution for in-flight dynamic reconfigurability. With these devices an advanced System-on-Chip (SoC) can be implemented, but also the system(More)
Using perfusion techniques in single proximal tubule segments of rat kidney, the relationship between net sodium movement and active transport of ions, as measured by the short-circuit method, has been studied. In addition, the role of the colloid-osmotic pressure gradient in proximal transtubular fluid and sodium movement has been considered. Furthermore,(More)
The transport properties of potassium (K) and sodium (Na) were studied in single distal tubules of Amphiuma using free-flow micropuncture techniques and stationary microperfusion methods. The transepithelial movement of labeled potassium was measured utilizing a three-compartment system in series in which the time course of tracer disappearance from the(More)
