General Features of Membranes

Essential for the compartmentalization that defi nes cells and organisms, biomembranes are fundamental to life. Early membranes played a crucial role in the origin of life as the structures that defi ned what stayed in and what was kept out of primordial cells. In addition to their compartmentalization function, membranes provide modern cells with energy derived from chemical and charge gradien...

General Features of Hormonal Coordination

General features of persistent virus infections.

Persistent virus infections are discussed from the virus point of view in terms of the bodily sites in which the infection persists. Glands and body surfaces are thought to be significant because they give the virus protection at the topographical level from immune forces, and because they are appropriate sites for the shedding of virus to the exterior. Germ cells are relevant sites because inf...

Distance Features for General Game Playing

General Game Playing (GGP) is concerned with the development of programs that are able to play previously unknown games well. The main problem such a player is faced with is to come up with a good heuristic evaluation function automatically. Part of these heuristics are distance measures used to estimate, e.g., the distance of a pawn towards the promotion rank. However, current distance heurist...

Acquisition of General Adaptive Features by Evolution

We investigate the following question. Do populations of evolving agents adapt only to their recent environment or do general adaptive features appear over time? We find statistically significant appearance of general adaptive features in a spatially distributed population of prisoner’s dilemma playing agents in a noisy environment. Multiple populations are evolved in an evolutionary algorithm ...
