Evolution of mycorrhiza systems
Naturwissenschaften, 2000Most terrestrial plants live in mutualistic symbiosis with root-infecting mycorrhizal fungi. Fossil records and molecular clock dating suggest that all extant land plants have arisen from an ancestral arbuscular mycorrhizal condition. Arbuscular mycorrhizas evolved concurrently with the first colonisation of land by plants some 450-500 million years ...

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.

Conceptualizing plant systems evolution
Current Opinion in Plant Biology, 2018Organisms inhabiting extreme environments are emerging models in systems evolution, enabling us to identify the molecular alterations effecting major phenotypic divergence through comparative approaches. Here I discuss possible physiological mechanisms underlying evolutionary adaptations to extreme environments both theoretically and in relation to ...

Manufacturing System Evolution
2018 15th International Conference on Service Systems and Service Management (ICSSSM), 2018This paper aims to investigate the transformation of the manufacturing system with the emerging technologies, namely the 3D printing technology in this research. The research results highlighted an evolution of manufacturing systems, from firm-based, to network-based, and to ecosystem-based.

Posters and short talks of the 1992 SIGCHI conference on Human factors in computing systems - CHI '92, 1992
Too often, attempted change and change planning suffers from inadequate insight, coordination, and involvement. Decision makers frequently get caught up in power/political contests, utilize and are impacted by cognitive (Anderson, 1991) or organizational (Grudin, 1991) structures and procedures that hinder beneficial cooperation/participation, and ...

Axiomathes, 2009
This is a review of the book ‘Memory Evolutive Systems; Hierarchy, Emergence, Cognition’, by A. Ehresmann and J.P. Vanbremeersch. I welcome the use of category theory and the notion of colimit as a way of describing how complex hierarchical systems can be organised, and the notion of categories varying with time to give a notion of an evolving system ...

Evolution–Communication P Systems
2003We propose a new class of P systems that use simple evolution rules (classical evolution rules without communication targets) and symport/antiport rules (for communication).

This completely rewritten new edition begins with an historical perspective of the place of the solar system in the universe. Evidence from meteorites is used to describe how the planets were formed and the giant planets are considered in the light of the discovery of new extrasolar giants. Other chapters discuss satellites, comets, centaurs, asteroids

Transformation of a task into a problem is forced by its increasing complexity (fig. 9.1). Complexity increase, in turn, is defined by four main attributes. Two of those attributes are related to the formulation of the task, while the other two directly bear on its solution.
