Human vascular cells are capable of stimudium obtained from cord veins was found lating granulopoiesis in agar culture of to be highly active in comparison to that human bone marrow cells. This effect was obtained from peripheral leukocytes. Enobtained by including vein fragments in dothelial cells within the bone marrow the culture or by using endothelial cells cavity are suggested as a local ...

1 Abstract1 DQRAP approaches the performance of an idealized M/D/1 queueing system. It provides the theoretical basis for developing practical protocols that can operate in diverse multiaccess channel environments such as LANs, MANs, WANs and satellite networks. In this paper we present DQLAN, a DQRAP based protocol that supports variable length frames in a high-speed LAN environment. The DQLAN...

The problem of two companies of agents with one-step memory playing game is investigated in the context of the Iterated Prisoner's Dilemma under the partial imitation rule, where a player can imitate only those moves that he has observed in his games with his opponent. We limit our study to the special case where the players in the two groups enjoy the same conditions on a fully connected netwo...
