.... edges leading from one page to another [4,5] There are also many networked systems that occur in biology, such as neural networks [6] food webs [7,8] and metabolic networks [9,10] In addition, studies have been made of distribution networks such as airline timetables [11] or blood vessels [12,13], river networks [14] and even networks of semantic linkage between words [15] There is however one area in which networks have been studied longer than any of these; social networks networks of connections between people have been studied in the sociology literature at least since the ....

....Images INTRODUCTION The fractal structure of the broncho vascular tree results from the nature of lung morphology. 1,2,3,4,5,6] It provides an efficient network for transporting air and blood to the alveoli and accounts for the fairly homogeneous tissue density across the lung parenchyma. [7] In CT scans, local density is recorded as the reduction in x ray intensity per unit thickness of material, using the arbitrarily defined Hounsfield scale. Air and water are assigned attenuation values of 1000 Hu and 0 Hu respectively, giving bone a range of values from around 80 Hu to 1000 Hu ....

....apart from other factors (the nucleus, for one) the mind (body, etc. can t be understood apart from the physical space that the organism is embedded in. Let s consider a relevant example. West et al. propose a model based on physical and geometric constraints to explain quarter power scaling (West, Brown, Enquist, 1997). As they note, a cat is a hundred times as large as a mouse so that one might expect a cat s metabolic rate to be one hundred times greater (Banegas, 1997) It is actually only about thirty times greater and is derived by taking the square root of the square root of the body mass and cubing it. ....

....state) this can lead to a large domino effect. The distribution of avalanches tends to a power function. Avalanches represent the agents. Many more attempts have been made to explain polo distributions on a case by case basis, focussing on a particular field of knowledge (e.g. Barlow 1994; West et al. 1997). The latter models do not take into account the universality of polo distributions. None of the above models has proposed a conceptual framework to serve as a theoretical basis applicable to seek the mechanisms of diversification from an undifferentiated start. 3 Defining the processes and ....
