"Self organized criticality" describes the tendency of strongly dissipative systems to show relaxation behavior involving a wide range of length and time scales .[1] The phenomenon is expected to be quite universal ; indeed, it has been looked for in such diverse areas as earthquake structure[2] and economics.[3] The idea provides an unifying concept for large scale behavior in systems with man...

When selecting a resource to exploit, an insect colony must take into account at least two constraints: the resource must be abundant enough to sustain the whole group, but not too large to limit exploitation costs, and risks of conflicts with other colonies. Following recent results on cockroaches and ants, we introduce here a behavioral mechanism that satisfies these two constraints. Individu...

Information spreading in self-organized networks is a frequently investigated research topic today; however, investigating the characteristics of application spreading by exploiting the direct connections between the user devices has not been widely studied yet. In this paper, we present our spreading model, in which we use Closed Queuing Networks to model the application spreading process. In ...

A mechanism for self-organization of the degree of connectivity in model neural networks is studied. Network connectivity is regulated locally on the basis of an order parameter of the global dynamics, which is estimated from an observable at the single synapse level. This principle is studied in a two-dimensional neural network with randomly wired asymmetric weights. In this class of networks,...

The early growth stage and growth evolution to a unique gold (Au) honeycomb nano-network on Si(111)7×7 at room temperature have been studied by direct filled-state and empty-state imaging by scanning tunneling microscopy (STM). The gold honeycomb structure is made up of six triangular gold clusters around the corner hole interconnected to one another in the dimer rows of the Si(111)7×7 substrate.

aphasia diagnosis is a challenging medical diagnostic task due to the linguistic uncertainty and vagueness, large number of measurements with imprecision, inconsistencies in the definition of aphasic syndromes, natural diversity and subjectivity in test objects as well as in options of experts who diagnose the disease. in this paper we present a new self-organized multi agent system that diagno...

The cybersecurity workforce is one of the most critical employment sectors in the world. The systems supporting the information technology requirements of the world’s government, power, and financial systems are interconnected more than any other system in the world. Despite the criticality and interconnectivity of these systems, the workforce has developed without a concentrated and standard v...

We can differentiate them according to staff size and system criticality (more dimensions exist, but these two serve well initially). For any point in the size–criticality space, methodology designers select a scope of concerns, prioritizing some quality of th...

Let H denote a collection of subsets of {1, 2, . . . , n}, and assign independent random variables uniformly distributed over [0, 1] to the n elements. Declare an element p-present if its corresponding value is at most p. In this paper, we quantify how much the observation of the r-present (r > p) set of elements affects the probability that the set of p-present elements is contained in H. In t...
