The estimation of the decoherence process of an open quantum system is of both theoretical significance and experimental appealing. Practically, the decoherence can be easily estimated if the coherence evolution satisfies some simple relations. We introduce a framework for studying evolution equation of coherence. Based on this framework, we prove a simple factorization relation (FR) for the l1...

Recently, attempts have been done to formalize Semantic Matchmaking, the process of finding potential matches between demands and supplies based on their logical relations with reference to a common ontology, in Description Logics (DLs). We extend the formalization to Packages-based Description Logics (P-DLs), modular extensions of DLs, in order to perform the matchmaking operation in contexts ...

Rather there is a great deal that has hitherto been unknown about what the eviden...

In this paper, we introduce the concept of (4/3) bandwidth interval based forecasting. The historical enrollments of the university of Alabama are used to illustrate the proposed method. In this paper we use the new simplified technique to find the fuzzy logical relations.

"in mathematics ... we find two tendencies present. On the one hand, the tendency toward abstraction seeks to crystallize the logical relations inherent in the maze of material that is being studied, and to correlate the material in a systematic and orderly manner. On the other hand, the tendency toward intuitive understanding fosters a more immediate grasp of the objects one studies, a live ra...

This article stresses the main lines of Thomas Aquinas's philosophy on the nature of the body-soul union. Following Aristotle, Aquinas sees the soul as a 'principle of life' which is intimately bound to a body. Together they form a non-contingent composition. In addition, the distinctive feature of the human soul is rationality, which implies that a human needs a mind to be what it is. However,...
