We describe the computation which resulted in the title of this paper Furthermore we give an analysis of the data collected during this computation From these data we derive the important observation that in the nal stages the progress of the double large prime variation of the quadratic sieve integer factoring algorithm can more e ectively be approximated by a quartic function of the time spen...

Payment for Performance (P4P) schemes by which physicians get a financial reward as long as they reach quality and efficiency targets provided by regulator have become increasingly popular in recent years in OECD countries (1) : in 2012, P4P program for primary care physicians were implemented in about 15 OECD countries. In the US, the number of P4P schemes has grown spectacularly, from 39 in 2...

Using a time series model to mimic an observed time series has a long history. However, with regard to this objective, conventional estimation methods for discrete-time dynamical models are frequently found to be wanting. In fact, they are characteristically misguided in at least two respects: (i) assuming that there is a true model; (ii) evaluating the efficacy of the estimation as if the post...
