Entertainment has always involved fictional characters in artificial settings. Effective use of artificial worlds and characters demands that the agents and worlds be believable and understandable. We examine the world and characters in the Road Runner cartoons, and show how the world, while not realistic, is internally consistent. We argue that the consistency of both the world and the actions...

The work of mathematical giants, such as Lobachevsky, Gauss, Riemann, Klein and Poincaré, to name a few, lies at the foundation of the study of the highly structured Riemann surfaces, which allow definition of holomorphic maps, corresponding to analytic maps in the theory of complex analysis. A topological result of Poincaré states that every path-connected Riemann surface can be realised by a ...

frequency of somaclonal variation in embryogenic calli and plants of olea europaea l cv.kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic dna (rapd) analysis. radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in omc medium supplemented with iba (5 mgl-1) and 2-ip (0.5 mgl-1). somatic embryogenesis was induced in calli of radic...

Introductions to Philosophy There are many good introductions to philosophy: [21], [51] and [1] have the advantage of being short and cheap. There are a few books [42, 10, 33] that introduce philosophical ideas by analysing films which raise philosophical issues. One of the advantages of these books is that they allow you to say that you are doing valuable research for this module while watchin...

Legged anthropomorphic robots are a prime example of complex, highly nonlinear control systems. For example, the dynamics of the DLR C-Runner (Compliant Runner), a legged robot designed at the German Aerospace Center (DLR) [1], is described by a nonlinear, high-dimensional hybrid system, see Fig. 1. The different hybrid domains, defined by whether the feet of the robot are in contact with the g...

With the goal of creating faster and more efficient methods of generating unique Ac/Ds insertional mutants in a population of Fragaria vesca, various methods of seed germination, kanamycin screening, and the effects of varying nitrogen fertilization on diploid strawberry have been examined. Seed germination was improved to 42% in B5 liquid medium compared to _ on MS solid medium. Kanamycin scre...

Changes in astrocyte morphology are primarily attributed to the fine processes where intimate connections with neurons form the tripartite synapse and participate in neurotransmission. Recent evidence has shown that neurotransmission induces dynamic synaptic remodeling, suggesting that astrocytic fine processes may adapt their morphologies to the activity in their environment. To illustrate suc...

The onset of the daily wheel running bout precedes dark onset by several hours in the early runner genetic variant of mice. Here, we test the hypothesis that timed daily administration of a melatonin agonist, ramelteon, or a benzodiazepine, triazolam, normalizes the timing of daily wheel-running rhythms in early runner mice. The daily profiles of wheel-running activity of early runner mice were...
