The Dirichlet Process mixture (DPM) model is a popular nonparametric Bayesian tool for modeling unknown distributions through mixtures of components. Integrating out the latent location variables in a DPM model leads to a product partition model. This paper describes a modefinding algorithm which quickly finds either the maximizer of the partition posterior or the maximizer of the partition lik...

This study was conducted to investigate the effects of engine operating conditions and exhaust aftertreatments on the mutagenicity of diesel particulate matter (DPM) collected directly in an underground mine environment. A number of after-treatment devices are currently used on diesel engines in mines, but it is critical to determine whether reductions in DPM concentrations result in a correspo...

In this paper I present a software tool for simulating a dynamic parimutuel market (DPM) based on an underlying model for the spread of information through a community. I use a standard gossip model for the information flow through the community. Typically these models are used to model network congestion, but I have taken a more literal interpretation of the “gossip”. The typical scenario for ...

Subjects deciding whether two objects presented at angular disparity are identical or mirror versions of each other usually show response times that linearly increase with the angle between objects. This phenomenon has been termed mental rotation. While there is widespread agreement that parietal cortex plays a dominant role in mental rotation, reports concerning the involvement of motor areas ...

The Dual Process Model (DPM) of Coping with Bereavement identified two oscillating coping processes, loss and restoration (Stroebe & Schut, 1999). The utility of the model is investigated in two studies. In the first, we carried out secondary analyses on a large-scale qualitative study that we had conducted previously. In the second, we conducted a small-scale study specifically examining the D...

As a cost-effective alternative to large supercomputers, Beowulf clusters are now deployed worldwide to support scientific computing. While Beowulf clusters yield high computing performance, they also pose several challenges: 1) Heat induced hardware failure makes large scale commodity clusters fail quite frequently, 2) Powering all the computer nodes without adapting to the varying work load m...

Cholangiocarcinoma arising in the liver can be classified into intrahepatic (or peripheral) cholangiocarcinoma (ICC) or perihilar cholangiocarcinoma, depending on the topographic location of the tumor along the intrahepatic biliary tree. Grossly, peripheral ICC usually presents as a mass-forming type, while perihilar ICC may present as mass-forming, periductal infiltrating, or intraductal-growt...

The global logic used by the brain for differentially encoding positive and negative experiences remains unknown along with how such experiences are represented by collections of memory traces at the cellular level. Here we contrast the cellular memory traces that form in the dorsal paired medial (DPM) neurons of Drosophila after conditioning flies with odors associated with aversive or appetit...
