A simple discrete mathematical model of a space, time and matter manifold, called a STaM, is described which is intended as a framework within which to study agents and multi-agent systems. In this paper we concentrate on two-dimensional Boolean STaMs, and report implemented algorithms for detecting agents within them. A specific example STaM is given, some experimental results presented, and c...

Embodied cognitive agents must be able to process two very different kinds of inputs: interoceptive stimuli (stimuli originating inside of the body) and natural language. To support these complex functionalities, developers must address, among other issues, two kinds of paraphrase: a) reformulation of the representation of physiological events (e.g., symptoms) in “lay” terms that can be underst...

This paper deals with the problem of designing a strategy profile which will enable collaborative interaction between agents. In particular, we consider the problem of information sharing among agents. Providing information in a single interaction as a response to queries is often nonbeneficial. But there are stable strategy profiles that make sharing information beneficial in the long run. Thi...

We show that steering control can be chosen to give bistability between parallel and antiparallel collective motion states for a continuous-time kinetic model of two agents moving in the plane with unit speed. Variational methods are used to determine the optimal input to the steering control of one of the agents which leads to switching between these collective states. For any given time inter...

AIM To analyze the genotoxic effect of two hydrogen peroxide-containing bleaching products on oral mucosal cells. MATERIALS AND METHODS The research was conducted on 22 individuals divided into two groups. Group 1 used ZOOM2 and group 2 the Opalescence BOOST bleaching agent. Specimens of the gingival and the upper lip mucosa were obtained before, immediately after, and 72 h after the bleachin...

We address an optimization problem in which two agents, each with a set of weighted items, compete in order to minimize the total weight of their solution sets. The latter are built according to a sequential game consisting in a fixed number of rounds. In every round each agent submits one item that may be included in its solution set. We study two natural rules to decide which item between the...

BACKGROUND In modern life, the incidence of traumatic injuries increases daily. In accidents which lead to trauma, massive bleeding is the main cause of death. Nowadays, many different chemical and herbal agents are available for quick control of bleeding. OBJECTIVES In this study, we compare the effectiveness of two different types of chemical agents for control of bleeding in an animal mode...

In this paper we address the problem of agents engaged in a distributed costly two-sided search for pairwise partnerships in Multi-Agent Systems (MAS). While traditional two-sided search mechanisms are based on a purely sequential search of all searchers, our mechanism integrates an ability of some of the agents to maintain several search efforts in parallel at each search stage. We show that i...
