Mathematical models of epidemic dynamics offer significant insight into predicting and controlling infectious diseases. The dynamics of a disease model generally follow a susceptible, infected, and recovered (SIR) model, with some standard modifications. In this paper, we extend the work of Munz et.al (2009) on the application of disease dynamics to the(More)
ACKNOWLEDGMENTS At the end of my Ph.D. journey, I find myself in the extremely fortunate position of having many people to thank. First and foremost, I owe much to my fantastic advisors, Rod Grupen and Andy Barto, who have been constant sources of wisdom and advice over the past six years. Rod has shown great trust in allowing me to pursue strange and(More)
Introduction Ever since the establishment of the fossil conifer genus Metasequoia Miki from a Cenozoic deposit in Japan (Miki, 1941) and the subsequent discovery of its living species, M. glyptostroboides Hu et Cheng, in south-central China (Hu & Cheng, 1948), the study of Metasequoia has attracted both neo-and paleobota-nists for the past 70 years (for(More)
With this paper, I attempt to explore possible neural correlates of morality. We define morality as the one part, structure, or process of the brain that could be linked to an innate ability to understand and determine right versus wrong. An understanding of right of right and wrong can provide us with a sense of guilt and empathy for an action or another(More)
Visual cortical simple cells show a strong preference for edges of a particular orientation[Hubel and Wiesel, 1962]. The receptive field of the cortical cell shows adjacent excitatory and inhibitory subfields, which are projections from ON-center and OFF-center LGN cells, respectively[Reid and Alonso, 1995]. Here we present a single cell model using ON and(More)
We'd like to understand how the brain works but that is, at least immediately, an impossible task. In the standard physics fashion we introduce a simplified model of the smallest workable unit of the big problem and make that the system we'd like to understand, namely the neuron. It is a well established idea in neuroscience that signals between neurons is(More)
