3a An instructive toy model: two paradoxes We start with a very simple random trigonometric polynomial (even simpler than 1c12): (3a1) X(t) = ζ cos t+ η sin t where ζ, η are independent N(0, 1) random variables. Its distribution is the image of γ under the map (x, y) 7→ (t 7→ x cos t+ y sin t). Time shifts of the trigonometric polynomial correspond to rotations of R, (3a2) X(t− α) = ζ(cos t cos...

The conditions which favour the growth of cyanobacteria and lead to blooms are nutrient enrichment (largely phosphorus but also nitrogen), warm temperatures, and calm stable water conditions such as those occurring in thermally stratified lakes and slow-flowing rivers. The latter may be the result of hydrology altered by abstraction practices. These conditions are often caused by human actions ...

Preterm Birth: Introduction Low birthweight defines neonates who are born too small, and preterm or premature birth are the terms used to define neonates who are born too early. With respect to gestational age, a newborn may be preterm, term, or postterm. With respect to size, a newborn may be normally grown or appropriate for gestational age, small in size or small-for-gestational age, or over...

Traditional query processing techniques have played a major role in the success of relational Database Management Systems over the last decade. However, they do not obviously extend to much more challenging, unorganized and unpredictable data providers, typical of emerging data intensive applications and novel processing environments. For them, advanced query processing and data integration app...

A 37-year-old man who had an atrial septal defect (ASD) corrected as an infant was found to be hypoxemic with a 22% shunt. An MRI scan revealed that the patient's inferior vena cava drained into his left rather than his right atrium, a previously undetected complication of his ASD repair 36 years before.

0.0 Introduction (BAS) This document details the design specifications for the first ever implementation of a complete Dava Vortex optical switching fabric. An introduction to the Data Vortex optical interconnection network topology can be found in the literature [Yang 2000, Yang 2001]. Moreover, previously published works [Yang 2002, Lu 2003, Lu 2004] have required the construction of small su...

The management of genetic resources is a complex, multi-faceted process. It involves a number of distinct stages, which are nevertheless linked and interrelated, from the selection of priority taxa, to the design and implementation of complementary conservation strategies and the development and exchange of the results of germplasm use (Maxted et al., 1997a). These different components generate...

Example 2 Figure 2 shows an analysis of some diabetes data from Efron, Hastie, Johnstone and Tibshirani (2004). The outcome Y is a measure of disease progression after one year. We consider four covariates (ignoring for now, six other variables): age, bmi (body mass index), and two variables representing blood serum measurements. A nonparametric regression model in this case takes the form Y = ...

m i x ed m et h ods re se a rch in spe cial edu c a ti o n . The mixed methods research process is described along with the role of the rationale and purpose of study. The reasons given in the literature for utilizing mixed-methods research are explicated, and the limitations of these reason frameworks are identified. We build on these frameworks by providing a comprehensive list of reasons for...
