Abstract A measurement of the fast neutron background in Gran Sasso underground laboratory has been performed by MOSCAB thermodynamic bubble chamber, a detector which identifies neutrons passing through metastable fluid scattering ions. The result this confirms results previously obtained using detectors based on totally different techniques, thus corroborating previous terms both integral inte...

We develop a Bayesian nonparametric autoregressive model applied to flexibly estimate general transition densities exhibiting nonlinear lag dependence. Our approach is related density regression using Dirichlet process mixtures, with the Markovian likelihood defined through conditional distribution obtained from mixture. This results in extension of mixtures-of-experts formulation. address comp...

Observations of the inner coma of Comet 19P/Borrelly with the camera on the Deep Space 1 spacecraft revealed several highly collimated dust jets emanating from the nucleus. The observed jets can be produced by acceleration of evolved gas from a subsurface cavity through a narrow orifice to the surface. As long as the cavity is larger than the orifice, the pressure in the cavity will be greater ...

One of the risks of large-scale geologic carbon sequestration is the potential migration of fluids out of the storage formations. Accurate and fast detection of this fluids migration is not only important but also challenging, due to the large subsurface uncertainty and complex governing physics. Traditional leakage detection and monitoring techniques rely on geophysical observations including ...

The typical application programmer is about to be swamped with a deluge of options for programming languages, libraries, frameworks and abstractions all designed to assist the inevitable need to parallelize new and existing codebases. Regardless of approach or level of abstraction provided, these programmers currently lack structured workflows to assist the development of parallel code. Workflo...
