When creating interactive drama computer games then it is frequently useful to be able to generate a plot to use as a background for the drama and to use as a knowledge base for Non-Player Characters. In this article a new engine is proposed that dynamically creates new game plots for a murder mystery based game. The game engine uses Bayesian networks to create a new plot based on a probability...

BACKGROUND Statistical tests of heterogeneity are very popular in meta-analyses, as heterogeneity might indicate subgroup effects. Lack of demonstrable statistical heterogeneity, however, might obscure clinical heterogeneity, meaning clinically relevant subgroup effects. METHODS A qualitative, visual method to explore the potential for subgroup effects was provided by a modification of the fo...

BACKGROUND & AIMS High-resolution manometry with spatiotemporal representation of pressure data is a technique that has developed during the past 10-15 years. We compared spatiotemporal and traditional line plot representation of manometry data in a group of medical students in terms of the ability of the user to come to a rapid and accurate diagnosis and evaluated user preferences for the 2 fo...

We prove that any Resolution proof for the weak pigeon hole principle, with n holes and any number of pigeons, is of length (2 n), (for some global constant > 0). One corollary is that a certain propositional formulation of the statement N P 6 6 P =poly does not have short Resolution proofs.

In our previous study (Wang et al., 2008) it is found that the relative frequency distribution of maximal repeat sequencesLog(P(k)) versus the frequency of appearance Log(k) exhibits scaling behavior, i.e. P(k) ~ k-γ. In order to valid the above findings are not due to an artifact, we redone the study by performing the randomize test, and reanalysis the results by plotting the relative frequenc...
