The argument put forward in this paper is that successful implementation of research into practice is a function of the interplay of three core elements--the level and nature of the evidence, the context or environment into which the research is to be placed, and the method or way in which the process is facilitated. It also proposes that because current… (More)
We study differentiation matrices that are skew-adjoint with respect to a diagonal discrete inner product, and show that these can be used to construct conservative and hence nonlinearly stable semidiscretizations of certain PDEs. Families of such finite differences of any order are constructed on arbitrary, periodic, one-dimensional grids and are studied… (More)
We study the zero-point energy of a massless scalar field subject to spheroidal boundary conditions. Using the zeta-function method, the zero-point energy is evaluated for small ellipticity. Axially symmetric vector fields are also considered. The results are interpreted within the context of QCD flux tubes and the MIT bag model.
