The Reflective Memory/Memory Channel @h&UC) system represents a modular bus-based system architecture that belongs to the class of distrtbuted shared memory systems. The RWMC system is characterized by an update consistenqv mechanism for shared data and egicient block transfers over the bus. This worh has tnw main goals. First, an extensive simulation anat’ysis using the firnch’onal Ru/MC simul...

As Koenig and Zhu showed, quotient of a triangulated category by a maximal 1-orthogonal subcategory becomes an abelian category. In this paper, we generalize this result to a maximal n-orthogonal subcategory for an arbitrary positive integer n.

In this paper, we propose real-time communication middleware which supports data dissemination with proxy extension. To fulfill stringent QoS requirement such as timing constraint, we employ push-based data delivery approach and real-time channel. Furthermore, by making the most of connected clients, we could permit the increased number of clients and extend the scalability. Since it is also de...

We show that the category of convergence approach spaces is a simultaneously reective and coreective subcategory of the category of latticevalued limit spaces. Further we study the preservation of diagonal conditions, which characterize approach spaces. It is shown that the category of preapproach spaces is a simultaneously reective and coreective subcategory of the category of lattice-valued p...

Let k be a field and let Q be a (finite) quiver. We fix a representation S with EndkQ S = k and Ext 1 kQ(S, S) = 0. In analogy to [3, Section 1] we consider the following subcategories of repk Q. Let M S be the full subcategory of all modules X with ExtkQ(S,X) = 0 such that, in addition, X has no direct summand which can be embedded into some direct sum of copies of S. Similarly, let MS be the ...

In 2x2 games we often solve them by writing arrows between outcomes in the matrix. I make this procedure precise and generalize it to all strategic games using some very basic category theory. I define a strategic game in categorical form in which outcomes are objects and preferences are arrows. A subcategory is formed by exclusion of arrows between outcomes that can not be reached unilaterally...

Results: Total laryngectomy was performed in 14/71 patients. Involvement of anterior commisure in local spreading of the cancer was found in 24/71 patients; total laryngectomy was performed in 13/24 and reconstructive surgery in 11/24. Selective resection of neck was done in 49 patients and metastases were found in 2 of these patients. Out of fifty-seven patients who had reconstructive laryngea...
