Rich gets simpler.
Network science plays a central role in the study of complex systems, offering a range of computational tools and, importantly, a common language to represent systems as diverse as the World Wide Web, the human brain, and social networks (1). Within the framework of network science, a system is modeled as a set of nodes, representing the individual units of the system, and a set of links, repre...
متن کاملPreferential attachment mechanism of complex network growth: "rich-gets-richer" or "fit-gets-richer"?
We analyze the growth models for complex networks including preferential attachment (A.-L. Barabasi and R. Albert, Science 286, 509 (1999)) and fitness model (Caldarelli et al., Phys. Rev. Lett. 89, 258702 (2002)) and demonstrate that, under very general conditions, these two models yield the same dynamic equation of network growth, dK dt = A(t)(K +K0), where A(t) is the aging constant, K is th...
متن کاملInternational Health Regulations—What Gets Measured Gets Done
The global spread of severe acute respiratory syndrome highlighted the need to detect and control disease outbreaks at their source, as envisioned by the 2005 revised International Health Regulations (IHR). June 2012 marked the initial deadline by which all 194 World Health Organization (WHO) member states agreed to have IHR core capacities fully implemented for limiting the spread of public he...
متن کاملSoftware Process Improvement: What gets measured gets done
A software quality management system (QMS) has been designed in a democratic fashion by programmers and has been approved by management. In order to motivate the programmers in following their own standards, measurement feedback is used for creating social pressure (peer pressure and management pressure). In nine out of ten cases this approach has been successful. Could the failure of the tenth...
متن کاملA Simpler Minimum Spanning
The problem considered here is that of determining whether a given spanning tree is a minimal spanning tree. In 1984, Komll os presented an algorithm which required only a linear number of comparisons, but nonlinear overhead to determine which comparisons to make. We simplify his algorithm and give a linear time procedure for its implementation in the unit cost RAM model. The procedure uses tab...
