Annual Review of Neuroscience, 1991
Evolution is the unifying theme of biological thought. It is therefore surprising that until recently it has little shaped the ideas of those who have sought principles among the cells and circuits of nervous systems. After relegation to an historic approach for many decades, an evolutionary perspective in neuroscience has revived, armed now with ...

The evolution of interorganizational systems
Journal of Information Technology, 1991In the literature on interorganizational systems (IOS) one encounters mainly examples of information systems that support highly structured transactions between organizations. However, the range of interorganizational activities also includes less structured interactions, such as negotiations and joint problem solving.

Evolution of the complement system
Immunology Today, 1991The ancestral form of the alternative pathway of complement activation probably originated as a primitive independent immune system. Subsequent evolution of an adaptive immune response drove the specialization of the classical pathway to connect antibody-mediated nonself recognition to the complement-dependent effector mechanisms.

Any experimental observation or any practical use of quantum phenomena relies on processes where a system evolves from a know initial state, and one performs measurements on it at some later time.

Evolution of transport systems
Journal of Theoretical Biology, 1968Abstract It is proposed that the evolution of transport catalysts for required nutrients may have preceded the evolution of biosynthetic pathways for these substances, or occurred at the same time as an alternative solution to the stress of nutrient depletion.

Animals and plants have a complex and effective immune system that protect them from invading microorganisms. The mechanisms of immunity are evolutionarily selected throughout host-pathogen interaction to be tolerant to self-antigens and to recognize nonself molecular patterns. Plants and animals share a germ line encoded diversity of receptors capable

Understanding evolution in systems of systems
2017 IEEE International Systems Engineering Symposium (ISSE), 2017Based on a literature analysis, this paper examines the nature of evolution in Systems of Systems (SoS) by attempting to answer why, where and how change occurs in this new kind of complex systems as well as what unprecedented underlying challenges makes it difficult to manage. This paper gives special focus on how state-of-the-art research efforts are

The Evolution of Semantic Systems
Annals of the New York Academy of Sciences, 2004Abstract: Semantic or cultural systems are sets of concepts connected by meaningful relationships, and they exhibit properties similar to those of populations of biological organisms. Drawing upon ideas from evolutionary biology and methods from information technology, this article explores the potential for research and engineering on the evolution ...

The evolution of the CEREC system
The Journal of the American Dental Association, 2006Early in 1980, the author anticipated the attraction of restoring posterior teeth with tooth-colored material. He conducted studies and developed the clinical concept of bonded ceramic inlays, at the same time raising the issue of the fast fabrication of the ceramic restorations.
