Equivalence and Stooge Strategies in Zero-Sum Games

Classes of two-person zero-sum games termed "equivalent games" are defined. These are games with identical value and identical optimal mixed-strategies but with different matrix entries and thus different opportunities for exploiting a nonrational opponent. An experiment was conducted to investigate the strategy-choice behavior of subjects playing pairs of these "equivalent games." Also investigated was the extent to which subjects would exploit a programmed stooge as a function of the degree to which the stooge departed from his optimal strategy mix. The results indicated that subjects learned to exploit the nonrational play of the stooge opponent. The game factor, on the other hand, seemed to have no significant effect upon the strategy-choice behavior of the players. The implications of these results are discussed in light of questions raised by previous research on decision-making in 2 x 2 zero-sum games.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67183/2/10.1177_002200277301700306.pd

Exploring urban metabolism—Towards an interdisciplinary perspective

© 2017 The Author(s) The discussion on urban metabolism has been long dominated by natural scientists focussing on natural forces shaping the energy and material flows in urban systems. However, in the anthropocene human forces such as industrialization and urbanization are mobilizing people, goods and information at an increasing pace and as such have a large impact on urban energy and material flows. In this white paper, we develop a combined natural and social science perspective on urban metabolism. More specifically, innovative conceptual and methodological interdisciplinary approaches are identified and discussed to enhance the understanding of the forces that shape urban metabolism, and how these forces affect urban living and the environment. A challenging research agenda on urban metabolism is also presented

Adaptive mitosis detection in large in vitro stem cell populations using timelapse microscopy

Reliable analysis of adult stem cell populations in in vitro experiments still poses a problem on the way to fully understand the regulating mechanism of these cultures. However, it is essential in the use of cultivated endogenous cells in stem cell therapies. One crucial feature during automated analysis is clearly the robust detection of mitotic events. In this work, we use the fully labeled stem cell benchmark data set CeTReS I in order to evaluate different approaches of mitosis detection: a purely time line based approach; a feature-based motility detector; and a detector based on the cell morphology changes, for which we also propose an adaptive version. We demonstrate that the approach based on morphological change outperforms the static detectors. However, the set of optimal features is changing over time, and thus it is not surprising that a feature set adapted to the systems confluency shows the best performance
