Between one-third and one-half of all cases of sepsis are known to be caused by gram-positive microorganisms through the cell wall component, e.g. lipoteichoic acid (LTA). Gram-positive bacteria are also known to induce encephalomyelitis and meningeal inflammation, and enhance the production of nitric oxide (NO) via expression of inducible nitric oxide(More)
Based on an entropy maximization principle both the spatial interaction model and the discrete choice model are discussed first to clarify the meaning of the accessibility and the utility function. We next introduce a mixture of expert that is one kind of probabilistic neural network and define the preference function in the MoE. The presented model can be(More)
