Gaviscon: not always entirely safe!

To cite: Shenvi A. BMJ Case Reports Published online: [Please include Day Month Year] doi:10.1136/bcr-2012007866 DESCRIPTION A 27 week gestation baby had a relatively uneventful initial neonatal course. At 3 weeks age, her feeds were increased to 200 ml/kg/day to optimise weight gain. She subsequently developed recurrent desaturations that were felt to be secondary to reflux. Gaviscon was added...

Large-Scale Byzantine Fault Tolerance: Safe but Not Always Live

The overall correctness of large-scale systems composed of many groups of replicas executing BFT protocols scales poorly with the number of groups. This is because the probability of at least one group being compromised (more than 1/3 faulty replicas) increases rapidly as the number of groups increases. In this paper we address this problem with a simple modification to Castro and Liskov’s BFT ...

Why "improved" water sources are not always safe.

Existing and proposed metrics for household drinking-water services are intended to measure the availability, safety and accessibility of water sources. However, these attributes can be highly variable over time and space and this variation complicates the task of creating and implementing simple and scalable metrics. In this paper, we highlight those factors - especially those that relate to s...

“ Noise ” in Ratings : Not Entirely Random

“Noise” in Ratings: Not Entirely Random I investigate the informational accuracy as opposed to informational content of credit ratings over time. The study presents an empirical analysis of the classification errors. Results suggest that greater the credit risk in the economy, the higher is the error rate. Of all binary classifications tested, classification error for dichotomous class of inves...
