The unique and little practiced characteristics of mobile as a marketing medium create a need to set up an action and research agenda regularly to foster the development of the mobile marketing value system. Numerous stakeholders take part in the network to deliver the mobile services. Strengthening their inter-organizational relationships is critical for the emerging value system to evolve. Ou...

We argue that the linear static potential is built in into the common procedure of extracting it from lattice Wilson loop measurements. To illustrate the point, we extract the potential by the standard lattice method in a model vacuum made of instantons. A beautiful infinitely rising linear potential is obtained in the case where the true potential is actually flattening. We argue that the flux...

This paper presents a new approach to segmentation using explicit hypotheses about the physics that creates images. We propose an initial segmentation that identifies image regions exhibiting constant color, but possibly varying intensity. For each region, we propose a set of hypotheses, each of which specifically models the illumination, reflectance, and shape of the 3-D patch which caused tha...

Adherence of Candida spp. to buccal epithelial cells in vitro was significantly reduced after both short- and long-term periods of yeast exposure to sub-inhibitory concentrations of octenidine and pirtenidine. In addition, the pretreatment of either Candida or the epithelial cells or both with the drugs reduced adherence, this being greatest when both types of cells were pretreated. No differen...

We model network formation when heterogeneous nodes enter sequentially and form connections through both random meetings and network-based search, but with type-dependent biases. We show that there is “long-run integration,” whereby the composition of types in sufficiently old nodes’ neighborhoods approaches the global type distribution, provided that the network-based search is unbiased. Howev...

We study the effects of adding a local perturbation in a pattern forming system, taking as an example the Ginzburg-Landau equation with a small localized inhomogeneity in two dimensions. Measuring the response through the linearization at a periodic pattern, one finds an unbounded linear operator that is not Fredholm due to continuous spectrum in typical translation invariant or weighted spaces...

The literature on the immunological aspects of tumor transplantation has been well reviewed by Hauschka (9), so it is necessary only to point out certain technical problems that form the basis for the present communication. The most striking recent advances in our knowledge of the genetics of tumor transplanta tion have been due to the work of Snell and his colleagues on the H-2 locus (13) and ...
