The Rise of Markov Chain Monte Carlo Estimation for Psychometric Modeling

Journal of Probability and Statistics, 2009
Markov chain Monte Carlo (MCMC) estimation strategies represent a powerful approach to estimation in psychometric models. Popular MCMC samplers and their alignment with Bayesian approaches to modeling are discussed.

Mazus dabieshanensis sp. nov. (Mazaceae) from eastern China

Nordic Journal of Botany, EarlyView.
Mazus dabieshanensis, a newly described species endemic to the Dabieshan Mountains in eastern China, is illustrated and described. Molecular phylogenetic analyses based on nuclear and chloroplast DNA sequences consistently demonstrate that this new species forms a stable clade with other Mazus species characterized by a pubescent ovary. Morphologically,

Genetic analysis of the rare forest bryophyte Dicranum viride in the boreo‐nemoral zone near the northern distribution range limit

Nordic Journal of Botany, EarlyView.
Bryophytes are important forest ecosystem elements, being an integral part of biodiversity. Genetic studies contribute to bryophyte population ecology by helping to understand species historical distribution patterns and genetic diversity at different scales.

Refinement of the Jensen integral inequality

Open Mathematics, 2016
In this paper we give a refinement of Jensen’s integral inequality and its generalization for linear functionals. We also present some applications in Information Theory.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

Oikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Comparison of Calorimetry and NMR Relaxometry Measurements of Epoxy Cure Kinetics

Journal of Polymer Science, EarlyView.
Single‐sided NMR monitors epoxy cure in three DGEBA/diamine systems, alongside benchmark DSC measurements. Fitting both datasets to a Kamal‐Malkin kinetic model shows NMR‐derived rate constants typically exceed DSC values, revealing an offset between gelation and chemical conversion.
