Deterministic SIR (Susceptible–Infected–Removed) models applied to varicella outbreaks

Greedy online histograms applied to deterministic sampling

Motivated by quantizing a continuous distribution for the purpose of sampling, we develop a new cost function for histograms and give two algorithms which approximate the optimal cost. Our algorithms are greedy and have optimality guarantees. The second is an adaption of the first in the context of data streams. In this context, we show that the histogram becomes stable fast, in any case; in ad...

Fast and Efficient Template Fitting of Deterministic Anisotropic Cosmological Models Applied to Wmap Data

We explore methods of fitting templates to cosmic microwave background (CMB) data, and in particular demonstrate the application of the total convolver algorithm as a fast method of performing a search over all possible locations and orientations of the template relative to the sky. This analysis includes investigation of issues such as chance alignments and foreground residuals. We apply these...

Applied Dynamical Systems London Taught Course Centre , Lectures 6 – 10 From Deterministic Chaos to Deterministic Diffusion

These are easy-to-read lecture notes for a short first-year Ph.D. student course on Applied Dynamical Systems, given at the London Taught Course Centre in Spring 2008 and 2009. The full course consists of two parts, each covering five hours of lectures. The first part by David Arrowsmith is on Basic dynamical systems, intermittency and autocorrelation. The present notes cover only the second pa...

Shingles (varicella zoster) outbreaks in patients with hyperparathyroidism and their relationship to hypercalcemia.

Shingles (varicella zoster) can be a presenting symptom of hyperparathyroidism and occurs twice as often (rate, 3.7%) among patients with hypercalcemia than in age-matched cohorts of patients >40 years of age who have normal calcium levels. The incidence of shingles increased in a linear fashion, from an annual rate of 1.5% among patients with serum calcium levels <10.5 mg/dL to 11% among patie...
