Alluvial visualization and computation of probabilities of transitions in frailty index states over an 8-year period using multi-state Markov models
(2021)The Frailty Index (FI) is an operationalization of frailty in older adults based on the accumulation of health deficits. FI cut-offs define the non-frail, prefrail and frail states. We described longitudinal transitions ... -
Estimating redshift distributions using Hierarchical Logistic Gaussian processes
(2019)This work uses hierarchical logistic Gaussian processes to infer true redshift distributions of samples of galaxies, through their cross-correlations with spatially overlapping spectroscopic samples. We demonstrate that ... -
Impact of COVID 19 Pandemic on Aviation Workers & The Aviation System
(Centre for Innovative Human System (CIHS), 2021)Worker wellness and mental health is hugely important in safety critical systems such as aviation. Aviation workers need to be fit for duty and aware of all risks that compromise their health and wellbeing. Work has the ... -
Transitions in frailty phenotype states and components over 8 years: evidence from The Irish Longitudinal Study on Ageing
(2021)Aim: Fried's frailty phenotype (FP) is defined by exhaustion (EX), unexplained weight loss (WL), weakness (WK), slowness (SL) and low physical activity (LA). Three or more components define the frail state, and one or two ...
