Physical design of biological systems

Proceedings of the 19th international symposium on Physical design, 2010
It may seem premature to worry about the design of of living systems when we do not yet fully understand their operation. However, the path to understanding is clear, and design will inevitably follow. It's not too early to think about how this might be structured.

Biological Movement and Laws of Physics

Motor Control, 2017
Living systems may be defined as systems able to organize new, biology-specific, laws of physics and modify their parameters for specific tasks. Examples include the force-length muscle dependence mediated by the stretch reflex, and the control of movements with modification of the spatial referent coordinates for salient performance variables.

Quantum physics and biological systems

Journal of Theoretical Biology, 1964
Abstract The nature of quantum concepts and principles is delineated, and the differences as well as the similarities between quantum physics and quantum biology are discussed. There seems to be no evidence at present for any violation or transcending of quantum laws and principles in biological phenomena.

Biological Physics—Origin and Perspectives

ChemPhysChem, 2002
Biology and Physics share common ancestors. The two sciences have drifted apart during the last century, although they have often mutually fertilized each other. Often the discovery of a new physical method has triggered dramatic progresses in biology but there are also numerous examples of biology-inspired new developments in physics.

The biological basis of physical activity

Medicine &amp Science in Sports &amp Exercise, 1998
Successful efforts to improve levels of physical activity in the population are contingent upon an accurate understanding of the determinants of habitual activity. While most research has focused on psychosocial and environmental influences, the potential effect of intrinsic biological control on regular activity has received little attention.

On the physical origin of biological handedness

Origins of Life, 1979
In the racemic conglomerate crystallization of over 1,000 samples of D,L-sodium-ammonium tartrate the effect of 32P beta irradiation on the weight, optical activity, and crystallite size was measured. Both weight and optical activity showed a statistical dependence on the intensity of beta irradiation.

Physical theories of biological co-ordination

Quarterly Reviews of Biophysics, 1971
Biological organization is manifestly different from the order of the nonliving world, and the study of biology is largely a search for the nature of this difference. The perspective and style with which we see this difference has changed in many respects as our knowledge of living systems has grown. Today, following the molecular biological revolution,

Medical and Biological Physics.

Archives of Internal Medicine, 1969
One year of college physics is usually sufficient to satisfy the physics prerequisites of the admission offices of most medical schools in the United States. As a result, the beginning resident in radiology, surgery, anesthesiology, or other disciplines concerned with basic physical principles is often faced with the consideration of fairly ...

Physical and Biological Setting

2001
Abstract Trees are the corner stone life form in the vegetation of Sonora.They are the species that affect and influence the survival of other species in the eco system. whether plants, animals, or people. Trees grow virtually everywhere in the state except in the extremely arid desert bordering the Rio Colorado.
