Summary: This tutorial paper reviews the use of advanced Monte Carlo sampling methods in Bayesian model updating for engineering applications, introducing different methods and comparing their performance. Three case studies demonstrate the advantages and limitations of these sampling techniques in parameter identification, posterior distribution sampling, and stochastic identification of model parameters.

Summary: This study assessed the relationships between exposure to melamine and DEHP and their combined exposure on early renal injury in pregnant women. The results showed that the current recommended tolerable daily intake levels for these chemicals were much lower than the levels of exposure in pregnant women, especially when considering coexposure to both chemicals.

Summary: In this study, the genetic and phenotypic relationships between anogenital distance (AGD) and body stature and fertility traits in dairy cattle were characterized. The results showed that AGD is a moderately heritable trait and is associated with reproductive success in lactating cows.

Summary: This article introduces a novel stochastic tree ensemble method called XBART, which combines regularization and stochastic search strategies with efficient recursive partitioning algorithms. It achieves state-of-the-art performance in prediction and function estimation. Simulation studies demonstrate that XBART provides accurate point-wise estimates of the mean function and does so faster than popular alternatives.

Summary: The R package walker extends Bayesian general linear models to handle time-varying effects of explanatory variables. This approach enables the modeling of intervention effects that gradually increase over time, such as changes in tax policy. The algorithm utilizes Hamiltonian Monte Carlo provided by Stan software to marginalize over the regression coefficients in a state space representation of the model, allowing for efficient low-dimensional sampling.

Summary: Sampling with integrator-dependent shadow Hamiltonians has shown improved properties compared to Hamiltonian Monte Carlo. The proposed algorithm, PS2HMC, combines the benefits of S2HMC with partial momentum refreshment, outperforming existing methods in various target distributions. Numerical experiments on different distributions and models demonstrate the effectiveness of the PS2HMC algorithm.

Summary: This study investigates the feasibility and practicability of using a Markov chain Monte Carlo (MCMC)-based Bayesian approach to identify the void in the cement-emulsified asphalt (CA) within the slab track system using measured vibration data. A newly developed model class identification algorithm is integrated with the MCMC-based Bayesian approach for the first time to identify CA mortar voids that may extend to neighboring regions. The proposed methodology is experimentally verified and provides accurate void location assessment, damage severity information, and uncertainty quantification of model parameters through posterior probability density functions (PDFs) using kernel density estimation.

Summary: MCMC algorithms are considered the gold standard technique for Bayesian inference, but the computational cost can be prohibitive for large datasets, leading to the development of scalable Monte Carlo algorithms. One type of these algorithms is SGMCMC, which reduces per-iteration cost by utilizing data subsampling techniques.

Summary: A Bayesian median autoregressive model was developed for time series forecasting, utilizing time-varying quantile regression at the median and a Laplace error instead of Gaussian error. Model parameters were estimated using Markov chain Monte Carlo, with Bayesian model averaging and model selection used to address model uncertainty. The methods showed favorable predictive performance in real data applications.

Summary: The research demonstrates the implementation of Logit, probit, and complementary log-log models from a Bayesian perspective using Gibbs sampling Markov chain Monte Carlo simulation methods. The logistic model performed best in univariate analysis, while bivariate analysis revealed some covariates are associated with the diseases.

Summary: This study introduces a Bayesian method to characterize latent brain states based on community structure, and demonstrates a new strategy to detect transitions between community structures in BOLD time series. Through in-silico model evaluation and empirical validation using HCP dataset, the results show distinctive community patterns in brain states during working memory tasks.

Summary: Medical imaging systems are often evaluated and optimized using objective measures of image quality, with the Bayesian Ideal Observer (IO) representing an upper limit for performance evaluation. A new MCMC method called MCMC-GAN, employing a GAN-based stochastic object model (SOM), shows promise in extending the applicability of MCMC methods for IO analyses of medical imaging systems.
