We study graph estimation and density estimation in high dimensions, using a family of density estimators based on forest structured undirected graphical models. For density estimation, we do not assume the true distribution corresponds to a forest; rather, we form kernel density estimates of...

A proton exchange membrane (PEM) fuel cell with interdigitated flow field was studied numerically. A three-dimensional, gas–liquid two-phase flow and transport model was developed and utilized to simulate the multi-dimensional, multi-phase flow and transport phenomena in both the anode and...

We study the two-body entanglement and mixture in a three-qubit XXZ spin chain in thermal equilibrium state at temperature T with an external magnetic field B. The effects of the magnetic field, the anisotropy and the temperature on the entanglement and mixture are considered. We show that the...
