Low rates of adoption of and low willingness to pay for preventative health technologies pose an ongoing puzzle. In the case of water-borne disease, the burden is high both in terms of poor health and cost of treatment. Inexpensive preventative technologies are available, but willingness to pay (WTP) for products such as chlorine treatment or ceramic filters has been observed to be low in a num...

Let A be the arrangement of hyperplanes consisting of the re ecting hyperplanes for the root system An 1. Let B = B(q) be the Varchenko matrix for this arrangement with all hyperplane parameters equal to q. We show that B is the matri x with rows and columns indexed by permutations with ; entry equal to qi( 1) where i( ) is the number of inversions of . Equivalently B is the matrix for left mul...

Since the potential for contaminant bioremediation in steam treated subsurface environments has not been explored, the thermal remedial treatment of a gasoline spill at Lawrence Livermore National Laboratory’s (LLNL) Livermore site provided an opportunity to study microbial community changes in the subsurface environment. Many terrestrial microorganisms die or become metabolically inactive if h...

The aim of this study was to determine the association of periodontitis with lifestyle-related comorbidities (LCs) using data in the Korean National Health Insurance Cohort Database from 2002 to 2013. This was a retrospective study involving a large national cohort with patient samples (representing 2% of the total Korean population) stratified on the basis of sociodemographic information. Usin...

Traffic Incident Management is a multi-jurisdictional process. Complications with communication, compatibility, coordination, institutional responsibilities and legal issues are inherent in a traffic incident management system. Increasing delay in incident clearance due to various conflicts has vital economical, safety, environmental and social impacts. Therefore, a thorough and rigorous modeli...

Understanding mechanisms of reversibility in of hippocampal atrophy has taken on increased importance as the relationship between cortisol dysregulation and atrophy has become increasingly clear. Cushing’s disease provides a compelling model for understanding these mechanisms, particularly as atrophy is reversible following treatment to reduce the hypercortisolemia. The present study focused on...
