This document contains results and other material that is supplementary to Duffie, Eckner, Horel, and Saita (2009). Section I extends the basic model to allow for unobserved cross-sectional heterogeneity of default risk. Section II allows for a nonlinear dependence of default intensity on distance to default, through a simple non-parametric specification. Section III provides some information o...

Background. A geriatric evaluation and management unit (GEM) manages elderly inpatients with functional impairments. There is a paucity of literature on frailty and whether this impacts on rehabilitation outcomes. Objectives. To examine frailty score (FS) as a predictor of functional gain, resource utilisation, and destinations for GEM patients. Methods. A single centre prospective case study d...

The concept of frailty has received increasing attention among clinicians and researchers. Clinicians often say, “I know frailty when I see it, but I can’t define it”. This is not surprising given that in spite of a growing body of knowledge, there is no widely accepted definition of frailty. The literature abounds with different models, criteria and definitions. While consensus has yet to be a...

BACKGROUND Despite having the third highest proportion of people aged 60 years and older in the world, Germany has been recently reported as having the lowest prevalence of frailty of 15 European countries. The objective of the study is to describe the prevalence of frailty in a large nationwide population-based sample and examine associations with sociodemographic, social support and health ch...

In this paper, we study denoising of multicomponent images. The presented procedures are spatial wavelet-based denoising techniques, based on Bayesian leastsquares optimization procedures, using prior models for the wavelet coefficients that account for the correlations between the spectral bands. We analyze three mixture priors: Gaussian scale mixture models, Bernoulli-Gaussian mixture models ...

Frailty is a common and important geriatric syndrome characterized by age-associated declines in physiologic reserve and function across multiorgan systems, leading to increased vulnerability for adverse health outcomes. Two major frailty models have been described in the literature. The frailty phenotype defines frailty as a distinct clinical syndrome meeting three or more of five phenotypic c...
