Schiff bases, having azomethine (RHC=N-R’) group and their metal complexes are widely used for industrial purposes and also reveal a wide range of biological applications. This review describes the most promising biological activities of Schiff bases and their metal complexes of cerium. A general idea for synthetic methodologies used for the synthesis of Schiff bases and their metal complexes i...

Reasoning about the nested beliefs of others is important in many multi-agent scenarios. While epistemic and doxastic logics lay a solid groundwork to approach such reasoning, the computational complexity of these logics is often too high for many tasks. Proper Epistemic Knowledge Bases (PEKBs) enforce two syntactic restrictions on formulae to obtain efficient querying: both disjunction and inf...

We present an epistemic logic equipped with time-stamps in the atoms and epistemic operators, which allows to reason not only about information available to the different agents, but also about the moments at which events happens and new knowledge is acquired or deduced. Our logic includes both an epistemic operator and a belief operator, which allows to model the disclosure of information that...

This paper motivates two bases for ascribing propositional semantic knowledge (or something knowledgelike): first, because it’s necessary to rationalize linguistic action; and, second, because it’s part of an empirical theory that would explain various aspects of linguistic behavior. The semantic knowledge ascribed on these two bases seems to differ in content, epistemic status, and cognitive r...

Inconsistent knowledge bases usually are regarded as an epistemic hell that have to be avoided at all costs. However, many times it is di cult or impossible to stay away of managing inconsistent knowledge bases. In this paper, we introduce an argumentation-based approach in order to manage inconsistent possibilistic knowledge bases. This approach will be exible enough for managing inconsistent ...

Since it is well-known that the Vandermonde matrix is ill-conditioned, while the interpolation itself is not unstable in function space, this paper surveys the choices of other new bases. These bases are data-dependent and are categorized into discretely l2-orthonormal and continuously L2-orthonormal bases. The first one construct a unitary Gramian matrix in the space l2(X) while the late...
