We construct an approximation for the moment Lyapunov exponent, the asymptotic growth rate of the moments of the response of a two-dimensional linear system driven by real or white noise. A perturbation approach is used to obtain explicit expressions for these exponents in the presence of small intensity noise. As an example, we study the moment stability(More)
Sixty-six adult patients with minimally displaced distal radial fractures were randomly assigned to treatment with either a plaster cast or a lightweight removable wrist splint. Outcome assessment was by clinical and radiological evaluation and an independent physiotherapy assessment. There were significant differences between the treatments for cast(More)
BACKGROUND The primary objective of this study was to assess whether there was an improvement in quality of life for patients with brain metastases as measured 1 and 2 months after a course of whole-brain radiotherapy. The secondary objective was to assess the level of agreement between patient and proxy quality of life scores. METHODS AND MATERIALS Sixty(More)
In this paper, an approximation for the moment Lyapunov exponent, the asymptotic growth rate of the moments of the response of two coupled oscillators driven by real noise, is constructed. A perturbation approach is used to obtain explicit expressions for these exponents in the presence of small intensity noise. The results are applied to study the moment(More)
Milk spoilage and low quality milk are of special concern to developing countries such as Rwanda. Our objective was to measure bacterial loads in milk via total bacterial count (TBC) in three major segments of the dairy value chain from farm to consumer, including milk transporters, milk collection centers, and milk kiosks. In all cases, the increase in(More)
OBJECTIVE We investigated whether the number of cigarettes smoked by women who had mildly abnormal cytologic study results could identify those at risk for high-grade dysplasia. STUDY DESIGN This was a prospective study of all women who were referred for colposcopy with a mildly abnormal cervical smear over a 4-year period. A detailed questionnaire was(More)
