Hastings-Metropolis algorithm on Markov chains for small-probability estimation***
ESAIM: Proceedings and Surveys, 2015 Shielding studies in neutron transport, with Monte Carlo codes, yield challenging problems of small-probability estimation. The particularity of these studies is that the small probability to estimate is formulated in terms of the ...

Bayesian inference for Hidden Markov Model [PDF]
Hidden Markov Models can be considered an extension of mixture models, allowing for dependent observations. In a hierarchical Bayesian framework, we show how Reversible Jump Markov Chain Monte Carlo techniques can be used to estimate the parameters of ...

Spatial and Temporal Patterns of Extreme Hourly Rainfall in the Hawaiian Islands
International Journal of Climatology, EarlyView.The extreme rainfall trends in Hawaiʻi were revealed by hourly rainfall data: Across islands, Kauaʻi and Hawaiʻi Island had larger events at a return period. Annual maximum series of 15 gauges showed significant positive trends. While extreme rainfall trends show increases or decreases regionally, the trends varied with rainfall duration.

A Markov chain Monte Carlo algorithm for Bayesian policy search
Systems Science & Control Engineering, 2018 Policy search algorithms have facilitated application of Reinforcement Learning (RL) to dynamic systems, such as control of robots. Many policy search algorithms are based on the policy gradient, and thus may suffer from slow convergence or local optima ...

Journal of Parenteral and Enteral Nutrition, EarlyView.Abstract Background Parenteral nutrition–associated liver disease is a severe complication in very low birth weight (≤1500 g) preterm neonates. Although previous pairwise meta‐analyses have compared individual intravenous lipid emulsions, their relative efficacy across all available formulations has not been established in this population.

Journal of Traumatic Stress, EarlyView.Abstract Adverse and benevolent childhood experiences (ACEs and BCEs, respectively) are uniquely associated with posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD); however, there is no systematic review on the mechanisms of these associations.

Journal of Traumatic Stress, EarlyView.Abstract The Momentary Posttraumatic Stress Disorder Checklist for DSM‐5 (PTSD; mPCL‐5) is a 10‐item ecological momentary assessment (EMA) version of the PTSD Checklist for DSM‐5 designed to capture momentary PTSD symptoms. Prior work supports its reliability and validity but is limited by small samples, short EMA periods, and untested stability across

The Journal of Wildlife Management, EarlyView.We estimated the distribution of the federally threatened wolverine (Gulo gulo) across the western United States in 2022, evaluated changes in distribution since 2017 (the last survey), and made inference on drivers of wolverine occurrence. This monitoring program and subsequent results are used by states to make management and conservation decisions ...
