Micrografting can be used to produce healthy seedlings, assess scion-rootstock compatibility and promote precocity. The first objective of this project was to study the impacts of in vitro micropropagation of four major Iranian pistachio cultivars, namely ‘Ahmad Aghaei’, ‘Akbari’, ‘Badami Sefid’ and ‘Kalle Ghochi’ in two different medium Murashige and Skoog (MS) and Driver and Kuniyuki...

Previous works have shown that the AGM theory cannot be used as the basis for defining contraction operators for several ontology representation languages. In this paper, we examine the postulate of relevance which has been proposed in the belief revision literature as a more intuitive alternative to the AGM postulate of recovery. Even though relevance and recovery have been proven to be equiva...

Self-adaptive systems are capable of adjusting their behavior to cope with the changes in environment and itself. These changes may cause runtime uncertainty, which refers to the system state of failing to achieve appropriate reconfigurations. However, it is often infeasible to exhaustively anticipate all the changes. Thus, providing dynamic adaptation mechanisms for mitigating runtime uncertai...

The AGM model for the revision and contraction of beliefs sets provides sets of postulates for each of the two cases. In the context of finite propositional logic, Katsuno and Mendelzon printed out some sets of postulates for the revision of belief bases which correspond to the postulates AGM revision of beliefs sets. In this paper, we present postulates for the contraction of propositional bel...

The functional exchangeability of the rev gene was assessed in transient transfection experiments by using in vitro-constructed rev and gag mutants of the following three primate lentiviruses: human immunodeficiency virus type 1 (HIV-1), HIV-2, and simian immunodeficiency virus from the African green monkey (SIV AGM). Cotransfection into SW480 cells of the rev and gag mutants derived from the D...

Belief change and non-monotonic reasoning are usually viewed as two sides of the same coin, with results showing that one can formally be defined in terms of the other. In this paper we show that we can also integrate the two formalisms by studying belief change within a (preferential) non-monotonic framework. This integration relies heavily on the identification of the monotonic core of a non-...

In this paper, we show that it is possible to accomplish belief revision in any logic which is translatable to classical logic. We start with the example of the propositional modal logic K and show that a belief operation in K de ned in terms of K0s translation to classical logic veri es the AGM postulates. We also consider the case of non-classical logics by taking Belnap's four-valued logic [...

is interesting in many ways; e.g., for certain complex parameters (η, a, b) one has an attractive AGM relation Rη(a, b) + Rη(b, a) = 2Rη ( (a + b)/2, √ ab ) . Alas, for some parameters the continued fraction Rη does not converge; moreover, there are converging instances where the AGM relation itself does not hold. To unravel these dilemmas we herein establish convergence theorems, the central r...
