A novel similarity measure for registering magnetic resonance (MR) and computed tomography (CT) images has been designed and built. MR-CT registration methods often rely on the statistical intensity relationship between the images. The proposed similarity measure instead depends on the statistical relationship between the complex phase order between the images. By utilizing the complex phase or...

Multivariate regular variation describes the relative decay rates of joint tail probabilities of a random vector with respect to tail probabilities of a norm (any norm) of this random vector, and it is often used in studying heavy-tail phenomena observed in data analysis in various fields, such as finance and insurance. Multivariate regular variation can be analyzed in terms of the intensity me...

The option-adjusted spread (OAS) is a standard measure in evaluation of mortgage-backed securities. In calculating the OAS, a prepayment model is incorporated to generate prepayment cashflows, however, no attention has been paid to a prepayment process and its associated probability measure. To illustrate the situation we examine two categories of prepayment models, the proportional hazards and...

Abstract We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using Sun as calibration source. As CHIME is pure drift-scan instrument, we rely on seasonal north–south motion to probe at different elevations. This semiannual range in elevation, combined with radio brightness Sun, enables that spans ∼7200 square degrees sky without need move tel...

We study the valuation and hedging of unit-linked life insurance contracts in a setting where mortality intensity is governed by a stochastic process. We focus on model risk arising from different specifications for the mortality intensity. To do so we assume that the mortality intensity is almost surely bounded under the statistical measure. Further, we restrict the equivalent martingale measu...

Because excessive anger in early childhood can predict later psychopathology, quantifying its intensity and time course is clinically important. Anger consists of a set of experiential, physiological, and behavioral responses whose coherence is sufficient to justify the assumption of a common latent variable that can vary in intensity. The relationships between anger intensity and various anger...

Human and rat have an innate preference for fat which may lead to obesity. This preference may be driven by the taste component linoleic acid, the principle free fatty acid found in corn oil. It has been shown that rats are capable of detecting linoleic acid within a solution. It is speculated that rats also perceive an increase in intensity when linoleic acid is added to the solution. This exp...
