The overwhelming number of radio stations, both online and over the air, makes the choice of an appropriate program difficult. By profiling the program content of radio stations using Self-Organizing Maps we provide a reflection of a station’s program type and give potential listeners a visual clue for selecting radio stations. Profiles of current broadcasts indicate which program type a statio...

We investigate how diversity in individual responses to unwanted interactions affects the evolution of cooperation modeled as a 2-person prisoner's dilemma. We combine adaptive networks and evolutionary game theory, showing analytically how the coevolution of social dynamics, network dynamics, and behavioral differences benefit the entire community even though myopic individuals still act in th...

Often, several different algorithms can solve a certain practical problem. Sometimes, algorithms which are successful in solving one problem can solve other problems as well. How can we decide which of the original algorithms is the most promising – i.e., which is more probable to be able to solve other problem? In many cases, the simplest algorithms turns out to be the most successful. In this...

There are two theories to account for linkage phenomena as observed in Oenothera. (1) Linked genes are always found within the same chromosome, that is, linkage is of the conventional or Drosophila type. The number of linkage groups is determined by the number of chromosomes in the genom, and bears no relation to chromosome configuration (SHULL 1928). (2) In addition to linkage of the ordinary ...

In 1976, Cameron et al. [2] proved that, if a finite generalized hexagon of order s admits a polarity, then either s or 3s is a perfect square. Their proof used standard eigenvalue arguments. Later on, Ott [3] showed that for a self polar finite thick generalized hexagon of order s, 3s always has to be a perfect square. His proof used Hecke algebras. It was surprising that one had to use this m...

BACKGROUND: Neurotransmitters (NTS) are endogenous chemicals secreted from neural terminals into the synaptic cleft of the chemical neurons in order to affect their receptors. NTS play vital physiological role as st...
