The binary power law (BPL) has been successfully used to characterize heterogeneity (overdispersion or small-scale aggregation) of disease incidence for many plant pathosystems. With the BPL, the log of the observed variance is a linear function of the log of the theoretical variance for a binomial distribution over the range...
Stress is an important concern among family caregivers in the United
States. Many caregivers face the demands of caring for an ill family member
for as many as eleven to twenty-four hours on a daily basis. Coping with
stress is an important topic for support groups and educational programs.

Consider the problem of exploring a large state-space for a goal state where although many such states may exist in the state-space, finding any one state satisfying the requirements is sufficient. All the methods known until now for conducting such search in parallel using multiprocessors fail to provide consistent linear...
In this paper, we study the short run price dynamics of imported fresh, farmed Atlantic and Pacific salmon on US regional markets. An Error Correction framework is used to specify a short run model. The results show a substitute relationship among the different salmon species in that an adjustment process...
We present discrete energy decay results for the Yee scheme applied to Maxwell's equations in Debye and Lorentz dispersive media. These estimates provide stability conditions for the Yee scheme in the corresponding media. In particular, we show that the stability conditions are the same as those for the Yee scheme...
We present a novel strategy for minimizing the numerical dispersion error in edge discretizations of the time-domain electric vector wave equation on square meshes based on the mimetic finite difference (MFD) method. We compare this strategy, called M-adaptation, to two other discretizations, also based on square meshes. One is the...
