Let IBn be the set of all irreducible matrices in Bn and let SIBn be the set of all symmetric matrices in IBn. Finding an upper bound for the set of indices of matrices in IBn and SIBn and determining gaps in the set of indices of matrices in IBn and SIBn has been studied by many researchers. In this paper, we establish a best upper bound for the set of weak exponents of indecomposability of ma...

In this work we consider the design principles of the Instance-Based Network (IBN), an extended version of a generic Content-Based Network(CBN). IBN acts as an overlay communication platform over which end-point entities, called contents, communicate independently from their physical locations while providing the flexibility of having different instances of the same content. The semantics of di...

Interest-based negotiation (IBN) is a form of negotiation in which agents exchange information about their underlying goals, with a view to improving the likelihood and quality of a deal. While this intuition has been stated informally in much previous literature, there is no formal analysis of the types of deals that can be reached through IBN and how they differ from those reachable using (cl...

Since Solomon Ibn Gabirol left the world and Moses Ibn Ezra, Jehudah Halevi, and Abraham Ibn Ezra died, the well of poetry has dried up, inspiration has disappeared, and God’s spirit no longer manifests itself. None of their successors can compare with them. We backward ones, like beggars, gather the crumbs and refuse that have fallen from their table. We hasten day and night over the ways trod...

Stroke or cerebrovascular accident (CVA) is caused by a disturbance of the blood supply to the brain and an accruing loss of brain function. The first recorded observations were in 2455 BC and it has been studied intensely by ancient physicians throughout history. In the early medieval period, Ibn Sina (980-1025 AD) called stroke sekteh and described it extensively. Some of Ibn Sina's definitio...
