AIM This study aimed to estimate the prevalence, incidence rate, and lifetime risk of developing atrial fibrillation (AF) in a population-based study of Swedish men. METHODS AND RESULTS The study is a part of 'The Study of Men Born in 1913', which is a longitudinal prospective cohort study of 855 men born in 1913 and living in the city of Gothenburg in Sweden. They were followed from the age ...

The different purposes present within a distributed information environment create the potential for repositories to enhance their metadata by capitalising on the diversity of metadata available for any given object. This paper presents three conceptual reference models required to achieve this optimisation of metadata workflow: the ecology of repositories, the object lifecycle model, and the m...

Background Antiretroviral therapy (ART) for HIV has significantly reduced morbidity and mortality, but the drugs can be expensive. This study aimed to estimate lifetime cost of management from Australian healthcare perspective. Methods A Markov cohort model, consisting 21 health states based on CD4 count line ART, simulated disease progression over persons living with HIV. We reported costs usi...

The Kerr Parametric Oscillator (KPO) is a nonlinear resonator system that often described as synthetic two-level system. In the presence of noise, switches between two states via fluctuating trajectory in phase space, instead following straight path. such trajectories makes it hard to establish precise count or even useful definition, “lifetime” state. Addressing this issue, we compare several ...

Predicting system lifetime is important to ensure safe and reliable operation of products, which requires integrated modeling based on multi-level, multi-sensor information. However, lifetime characteristics of equipment in a system are different and failure mechanisms are inter-coupled, which leads to complex logical correlations and the lack of a uniform lifetime measure. Based on a Bayesian ...
