Variance Matrix Priors for Dirichlet Process Mixture Models With Gaussian Kernels

International Statistical Review, EarlyView.
Summary Bayesian mixture modelling is widely used for density estimation and clustering. The Dirichlet process mixture model (DPMM) is the most popular Bayesian non‐parametric mixture modelling approach. In this manuscript, we study the choice of prior for the variance or precision matrix when Gaussian kernels are adopted.

Cap‐to‐bell stage molar tooth morphogenesis occurs through proliferation‐independent sulcus sharpening and condensation‐associated tension in the dental papilla

Journal of Anatomy, EarlyView.
Experiments in this article show that the development of the mouse molar tooth from cap‐stage to bell‐stage is not proliferation‐dependent, nor does it rely on confinement by condensing mesenchyme. Instead, morphogenesis is associated with condensation and tension in the mesenchyme of the dental papilla subadjacent to the forming cusps and sulcus ...

Things at Work: How Things Contribute to Performing Work

Journal of Management Studies, EarlyView.
Abstract A crucial question for organizations is what constitutes work performance. While the importance of human competence and motivation to work performance has been established, less well understood is how ‘things’ – such as algorithms, tools, instruments, and raw materials – contribute to work performance.

Case reports of oral appliance therapy on three young adults with Down syndrome and OSA

Journal of Prosthodontics, EarlyView.
Abstract Patients with Down syndrome (DS) have a high incidence of obstructive sleep apnea (OSA) due to hypotonia, weight, underdeveloped midface, and relative macroglossia. This article presents three cases of young adults with DS, who were diagnosed with mild to severe OSA and unable to tolerate positive airway pressure therapy.

Empirical likelihood for martingale differences

Journal of Time Series Analysis, EarlyView.
In this article, we consider an empirical likelihood with vector observations that are martingale differences and prove a Wilks' type theorem under a conditional Lindeberg condition. We then generalize this result to approximate martingale differences.
