63 Three soils (a silt loam, loamy sand, sandy loam) found in Mississippi and pure silica sand were treated with fipronil and bioassayed using eastern subterranean termites, Reticulitermes jlavipes. Soils were treated with aqueous solutions ofTermidor (fipronil) at concentrations of 0, 0.12, 0.25,2.5, 5.0 and 20.0 ppm (wt AI: wt soil) that brought the soils to 15% moisture. Estimated lethal con...

Social media becomes a vital part in our daily communication practice, creating a huge amount of data and covering different real-world situations. Currently, there is a tendency in making use of social media during emergency management and response. Most of this effort is performed by a huge number of volunteers browsing through social media data and preparing maps that can be used by professi...

Volume rendering is a technique for visualizing 3D arrays of sampled data. Volume rendering, though capable of performing very effective visualization, is very computationally intensive. Semi-boundary (SB) is a compact data structure used to encode extracted surface from volume data. In this paper, we describe an incremental algorithm to shorten rendering of SB nodes. We define two projection r...

We explore the relation between resummation and explicit multi-loop calculations for QCD hard-scattering amplitudes. We describe how the factorization properties of amplitudes lead to the exponentiation of double and single poles at each order of perturbation theory. For these amplitudes, previously-observed relations between single and double poles in different 2 → 2 processes can now be inter...

This research was conducted to develop flowable slurry containing fibrous residuals from pulp and paper mills. Two types of flowable slurry containing ASTM Class C fly ash were produced: fly ash slurry and sandy slurry. Often, the fly ash slurry made without fibrous residuals showed a tendency to set rapidly, and become unworkable. When the cement-to-fly ash ratio was increased to extend the ti...

As the world population grows, recent climatic changes seem to bring powerful storms to populated areas. The impact of these storms on utility services is devastating. Hurricane Sandy is a recent example of the enormous damages that storms can inflict on infrastructure, society, and the economy. Quick response to these emergencies represents a big challenge to electric power utilities. Traditio...

We investigate a parallel implementation of an irregular particle simulation algorithm. We concentrate on the issue which programming and system support is needed to yield an eecient implementation for a large number of processors. As execution platform we use the SB-PRAM, a shared memory machine with up to 4096 processors.

We study the computational question whether a given polytope or spectrahedron SA (as given by the positive semidefiniteness region of a linear matrix pencil A(x)) is contained in another one SB . First we classify the computational complexity, extending results on the polytope/polytope-case by Gritzmann and Klee to the polytope/spectrahedron-case. For various restricted containment problems, NP...

Van Glabbeek and Goltz (and later Fecher) have investigated the relationships between various equivalences on stable configuration structures, including interleaving bisimulation (IB), step bisimulation (SB), pomset bisimulation and hereditary history-preserving (H-H) bisimulation. Since H-H bisimulation may be characterised by the use of reverse as well as forward transitions, it is of interes...

Adaptive learning capacity is a critical component of community resilience that describes the ability of a community to effectively gauge its vulnerability to the external environment and to make appropriate changes to its coping strategies. Traditionally, the relationship between government and community learning was framed within a deterministic paradigm. Learning outcomes were understood to ...
