Adaptation in biological networks

2014 IEEE International Conference on Control Science and Systems Engineering, 2014
In this paper a mechanism for parameter identification of a biological system is proposed. The local dynamic is considered nonlinear with parameters nonlinearly parameterized. The results are applied to a glycolitic oscillators.

Biological adaptabilities and quantum entropies

Biosystems, 2002
The entropy-based theory of adaptability set forth by Michael Conrad in the early 1970s continued to appear in his work for over two decades, and was the subject of the only book he published in his lifetime. He applied this theory to a host of subjects ranging from enzyme dynamics to sociology.

Thermal Adaptations in Biological Membranes: Is Homeoviscous Adaptation the Explanation?

Annual Review of Physiology, 1995
The phase behavior and physical properties of lipids in biological membranes are exquisitely sensitive to changes in temperature (50). Because membranes (a) act as physical barriers to solute diffusion, (b) mediate the transmembrane movement of specific solutes, (c) regulate the utilization of energy stored in transmembrane ion gradients, Cd) provide ...

Adaptation and Optimization of Biological Transport Networks

Physical Review Letters, 2013
It has been hypothesized that topological structures of biological transport networks are consequences of energy optimization. Motivated by experimental observation, we propose that adaptation dynamics may underlie this optimization. In contrast to the global nature of optimization, our adaptation dynamics responds only to local information and can ...

Culture and Biological Adaptation

American Anthropologist, 1965
THE results of one phase of a recently completed study which are pertinent to the question of the biological adaptiveness of culture are presented here. For the purpose of interpreting the genetic characteristics of Pacific Island peoples, research was initially directed to the problem of identifying the determinants of size, structure and dynamics of ...

Biological Adaptation: A Reply

Philosophy of Science, 1972
Michael Ruse [3] has criticized the distinction between biological function and evolutionary adaptation that I argued for in my article “Biological Adaptation” [2]. I shall show below that Ruse's criticisms are not, for the most part, well taken and that the distinction remains as I made it.

Ethanol and biological membranes: Injury and adaptation

Pharmacology Biochemistry and Behavior, 1983
Ethanol intoxication affects the protein and lipid constituents of biological membranes. Mitochondria exhibit specific decreases in components of the electron transport chain and in protein synthesis. In vitro ethanol reduces the transition temperatures of membrane-bound enzyme activities and decreases the order parameter.

Adaptive optimization and the harvest of biological populations

Mathematical Biosciences, 1996
Adaptive management of renewable biotic resources accounts explicitly for uncertainties in system responses to management and recognizes the importance of reducing uncertainties while pursuing other management goals. An adaptive approach to the harvest of wildlife populations that are subject to (1) uncontrollable environmental variation, (2 ...

Human Biological Adaptability

Science, 1969
Adaptation is an aspect of virtually all questions of human biology. Besides their interest in evolution through adaptive selection of the primates, including man, physical anthropologists are concerned with biological adaptability as a human attribute.
