Ants of the genus Tatuidris Brown and Kempf (Formicidae: Agroecomyrmecinae) generally occur at low abundances in forests of Central and South America. Their morphological peculiarities, such as mandibular brushes, are presumably linked with specialized predatory habits. Our aims were to (1) assess the Tatuidris abundance in an evergreen premontane forest of Ecuador; (2) detail morphological cha...

The DNA structure of a fragment containing the SV40 termination sequences was examined using gel mobility assays. The region is shown to contain a DNA bend as evidenced by an abnormal mobility that is progressively accentuated as the temperature is lowered. This represents the strongest example of DNA bending among the collection of SV40 fragments studied. The same fragment was shown previously...

Machine learning and game theory are two important directions of AI. The former usually assumes data is independent of the models to be learned; the latter usually assumes agents are fully rational. In many modern Internet applications, like sponsored search and crowdsourcing, the two basic assumptions are violated and new challenges are posed to both machine learning and game theory. To better...

The aim of this paper is to illustrate and sensitize reader to the variety of perspectives and the fundamental nature of organizations as stable/stabilizing systems and as multi-perspective action systems. Researchers have been explicitly thinking about MAS/DAI organizations and attempting to link formal (human) organization theory with MAS/DAI models for at least twenty years. Despite this, th...

A stable herd of fattening cattle comprising 9 steers and a heifer, which had been kept together over a month in a dry-lot, was observed for 13 days (0600-1900 h) to determine the diurnal distribution of the frequency of social licking interactions and to examine the relationship between social licking and agonistic behaviour. Agonistic behaviour was also classified into total (fighting, buntin...

Peer reviewing is a widely accepted mechanism for assessing the quality of submitted articles to scientific conferences or journals. Conference management systems (CMS) are used by conference organizers to invite appropriate reviewers and assign them to submitted papers. Typical CMS rely on paper bids entered by the reviewers and apply simple matching algorithms to compute the paper assignment....

This paper investigates a bio-inspired framework, iNetEGT/C, to build adaptive, cooperative and stable network applications. In this framework, each application is designed as a decentralized set of agents, each of which provides a functional service and possesses biological behaviors such as migration, replication and death. iNet-EGT/C implements an adaptive behavior selection mechanism for ag...
