Analyzing the Pace of Play in Golf

We develop performance approximations that can help manage the pace of play in golf. In previous work we developed a stochastic model of successive groups of golfers playing on an 18-hole golf course and derived expressions for the capacity (maximum possible throughput) of each hole and the golf course as a whole. That model captures the realistic feature that, on most holes, more than one grou...

Models to Study the Pace of Play in Golf

Successive groups of golfers playing on an 18-hole golf course can be represented as a network of 18 queues in series, but the model needs to account for the fact that, on most holes, more than one group can be playing at the same time, but with precedence constraints. We show how to approximate the model of group play on each hole by a conventional G/GI/1 single-server queue, without precedenc...

Forever Young

Propagation of a species requires periodic cell renewal to avoid clonal senescence. Liu et al. (2010) now describe a new mechanism of cell renewal in budding yeast, in which damaged protein aggregates are transported out of the daughter buds along actin cables to preserve youthfulness.

Revision Forever!

Revision is a method to deal with non-monotonic processes. It has been used in theory of truth an an answer to semantic paradoxes as the liar, but the idea is universal and resurfaces in many areas of logic and applications of logic. In this survey, we describe the general idea in the framework of pointer semantics and point out that beyond the formal semantics given by Gupta and Belnap, the pr...
