1. Repeatability is important in determining how traits are affected by selection, but it is largely unstudied for most physiological characters other than locomotory performance. We examined the repeatability of aerobic capacity, measured as maximum 0, is an integrated index of metabolic performance that can be intuitively linked to fitness because it sets(More)

— We show how distributed randomized network coding, a robust approach to multicasting in distributed network settings, can be extended to provide Byzantine modification detection without the use of cryptographic functions. Distributed randomized network coding is a flexible, robust approach for multi-source multicast in distributed network settings. In(More)

This paper provides evidence that happiness raises productivity. In Experiment 1, a randomized trial is designed. Some subjects have their happiness levels increased; those in a control group do not. The treated subjects are shown to have 12% greater productivity in a paid piece-rate task. They alter their output but not per-piece quality of work. To check(More)
