Physics of a random biological process

Physical Review E, 1994
We analyze the successive fluctuations of the daytime and nighttime sleep pattern of a newborn baby by using tools of far-from-equilibrium statistical physics. We find that this class of natural random biological process displays a remarkable long-range power-law correlation that extends for, at least, the first six months of life.

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.

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.

The Physical and Biologic Properties of Cavit

The Journal of the American Dental Association, 1971
The physical properties of Cavit and the response of dental pulp to this temporary filling material were tested. Cavit has a high linear expansion that apparently is caused by water sorption and that probably produces its sealing effect. Insertion of Cavit into dry cavity preparations caused aspiration of odontoblasts and an accompanying pain; no pain ...

Physical and Biological Targeting of Radiotherapy

Acta Oncologica, 1999
Targeting of radiotherapy can be based on improving physical dose distribution of radiation delivered or on utilization of specific biological processes for targeting. Tools for physical targeting include brachytherapy, hadron therapy, conformal radiotherapy, stereotactic radiotherapy, stereotactically guided conformal fractionated radiotherapy, and ...

From physical to biological time

Mechanisms of Ageing and Development, 1988
Time is a primitive (i.e. fundamental) notion, and the various concepts** that have been so far derived from this notion in various scientific domains do not cover all facets of it. Time in mechanics, either classical, quantal or relativistic, is devoid of directionality, the "arrow", i.e.

Biological Influence of Physical Exercise on Hemostasis

Seminars in Thrombosis and Hemostasis, 2009
Some of the benefits of physical activity may result from effects on hemostasis. However, the increased burden of cardiovascular complications and sudden death occurring during and immediately after exercise prompts investigation to elucidate the biological relationship between physical exercise and hemostatic function. Although both the hemostatic and
