When Viruses Play Team Sports: Mixed Infections in Plants

Avian Influenza: Mixed Infections and Missing Viruses

A high prevalence and diversity of avian influenza (AI) viruses were detected in a population of wild mallards sampled during summer 2011 in California, providing an opportunity to compare results obtained before and after virus culture. We tested cloacal swab samples prior to culture by matrix real-time PCR, and by amplifying and sequencing a 640bp portion of the hemagglutinin (HA) gene. Each ...

Game Intelligence in Team Sports

We set up a game theoretic framework to analyze a wide range of situations from team sports. A fundamental idea is the concept of potential; the probability of the offense scoring the next goal minus the probability that the next goal is made by the defense. We develop categorical as well as continuous models, and obtain optimal strategies for both offense and defense. A main result is that the...

Contagious Infections in Competitive Sports

Many athletes believe that physical training enhances immunity and helps prevent upper respiratory tract infection (URTI) like the common cold or “flu” (influenza). They also believe that physical activity and fitness help them overcome any minor infections they do get. On the other hand, based largely on anecdotes and on popularization of a link between physical or psychological stress and “im...

Synchronizing Sensed Data in Team Sports

55 When dealing with sensor data for a team sport, it is often useful to be able to query across multiple sensors and thus to be able to compare data from several players for any given moment in time. In order to do this, the data from all sensors must be synchronized so that the start time of the game or activity can be identified in the data from each individual sensor. This is necessary beca...
