Let q(r) , r = |x| , x ∈ R3 , be a real-valued square-integrable compactly supported function, and [0, a] be the smallest interval containing the support of q(r) . Let A(α′, α) = A(α′ · α) be the corresponding scattering amplitude at a fixed positive energy, k2 = 1 . Let δ` be the phase shifts at k = 1 . It is proved that lim `→∞ ( 2`+ 1 e |δ`| 1 2` ) = a , provided that q(r) does not change si...

We present the case for allowing independent updates on replicated databases. In autonomous, heterogeneous , or large scale systems, using two-phase commit for updates may be infeasible. Instead, we propose that a site may perform updates independently. Sites that are available can receive these updates immediately. But sites that are unavailable, or otherwise do not participate in the update t...

Local heat transfer coefficients and pressure drops during boiling of the dielectric liquid fluorinert FC-77 in parallel microchannels were experimentally investigated in recent work by the authors. Detailed visualizations of the corresponding two-phase flow regimes were performed as a function of a wide range of operational and geometric parameters. A new transition criterion was developed for...

This paper reports the outcomes of a two-phase investigation into leadership development in SMEs in the South West of England that aimed to devise an educational programme matched specifically to their needs. Phase One aimed to determine the demand for leadership development in SMEs in the Region by means of face-to-face interviews with 20 SME directors and was supported by interviews with lead...

Existing IE systems tend to focus on a tight window of context surrounding the desired information to be extracted. This research addresses shortcomings of these systems by introducing a two-phase approach to IE that incorporates global relevance information with local contextual evidence, to effectively extract information from free text.

We present our pilot research on automatically extracting subevents from a domain-specific corpus, focusing on the type of subevents that describe physical actions composing an event. We decompose the challenging problem and propose a two-phase approach that effectively captures sentential and local cues that describe subevents. We extracted a rich set of over 600 novel subevent phrases. Evalua...

Subsurface two-phase flow in porous media often takes place in reservoirs with a high ratio between the associated lateral and vertical extent and the lateral and vertical flow time scales. This allows for a two-scale approach with effective quantities for two-dimensional horizontal flow equations obtained from reconstructed hydrostatic vertical pressure and saturation distributions. Here, we d...
