Simulation leagues: Analysis of competition formats
"... Abstract. The selection of an appropriate competition format is critical for both the success and credibility of any competition, both real and simulated. In this paper, the automated parallelism offered by the RoboCupSoccer 2D simulation league is leveraged to conduct a 28,000 game round-robin betw ..."

Media as Watchdogs: The Role of the News Media in Electoral Competition." Working paper
, 2004
"... Abstract. We develop an equilibrium model to analyze the role of the media in electoral competition. Policy payos in the model are state dependent. We show that voters cannot infer the state directly from o-equilibrium party policies. As a result, party policies do not converge to the median voter&a ..."

Mass media that are likely to have the same policy preference as the median voter are more eective in promoting electoral competition, re-sulting in greater policy convergence. However, since voters are rational, media that are more biased need not be less eective. JEL
Fish‘n’Steps: Encouraging Physical Activity with an Interactive Computer Game
- Proceedings of UbiComp’06
, 2006
"... Abstract. A sedentary lifestyle is a contributing factor to chronic diseases, and it is often correlated with obesity. To promote an increase in physical activity, we created a social computer game, Fish'n'Steps, which links a player’s daily foot step count to the growth and activity of an ..."

RESEARCH ARTICLE An Essential Role of the Arginine Vasotocin System in Mate-Guarding Behaviors in Triadic Relationships of Medaka Fish (Oryzias
"... To increase individual male fitness, males of various species remain near a (potential) mat-ing partner and repel their rivals (mate-guarding). Mate-guarding is assumed to be mediated by two different types of motivation: sexual motivation toward the opposite sex and competi-tive motivation toward t ..."

The male-male competition re-sulted in one male occupying a dominant position near the female while interfering with the other male's approach of the female. Paternity testing revealed that the dominant male had a significantly
Joint beamforming and scheduling for a multiantenna downlink with imperfect transmitter channel knowledge
- IEEE J. Select. Areas Commun
, 2007
"... We consider the downlink of a wireless system where the base-station has M ≥ 1 antennas and K user terminals have one antenna each. We study the weighted rate sum maximization in the case of non-perfect Channel State Information at the Transmitter (CSIT). Some relevant downlink optimization problems ..."

For the simpler (but still non-convex) approximated problem, we propose a powerful heuristic solution based on greedy user selection and a gradient iteration that converges to a local maximum of the objective function. This method yields very competitive re-sults with relatively low computational
Learning semantic distance from community-tagged media collection

, 2009
"... This paper proposes a novel semantic-aware distance met-ric for images by mining multimedia data on the Internet, in particular, web images and their associated tags. As well known, a proper distance metric between images is a key ingredient in many realistic web image retrieval engines, as well man ..."

Phylogenetic Clustering of Soil Microbial Communities by 16S rRNA but Not 16S rRNA Genes
"... We evaluated phylogenetic clustering of bacterial and archaeal communities from redox-dynamic subtropical forest soils that were defined by 16S rRNA and rRNA gene sequences. We observed significant clustering for the RNA-based communities but not the DNA-based communities, as well as increasing clus ..."

Duopoly Competition with Common Shareholders
, 2008
"... We develop a methodology for evaluating competition and welfare when shareholders hold (partial) positions in more than one competi-tor. We consider different models of product market competition and shareholder control. In each case, we derive consumer welfare as a function of shareholding Herfinda ..."

Tractable optimal competitive scheduling

, 2006
"... In this paper we describe the problem of Optimal Competi-tive Scheduling, which consists of activities that compete for a shared resource. The objective is to choose a subset of activ-ities to schedule, sequence them, and decide how much time they are allowed, in such a way that temporal and resourc ..."

Often the latter approach stimulates an interest in the mechanisms that prevent plant species with similar niches from excluding each other through competition. Ten years
