In agile ontology-based software engineering projects support for modular reuse of ontologies from large existing remote repositories, ontology project life cycle management, and transitive dependency management are important needs. The contribution of this paper is a new design artifact called OntoMaven combined with a unified approach to ontology modularization, aspect-oriented ontology devel...

The technology of opinion extraction allows users to retrieve and analyze people’s opinions scattered over Web documents. We define an opinion unit as a quadruple consisting of the opinion holder, the subject being evaluated, the part or the attribute in which the subject is evaluated, and the value of the evaluation that expresses a positive or negative assessment. We use this definition as th...

One of the fundamental issues in Aspect-Oriented approaches is aspect-to-aspect interference, which occurs when multiple aspects are deployed jointly such that different composition orders may give rise to various inconsistency problems. This paper describes how aspect precedence can be specified explicitly at the modeling level in order to derive a correct composition order and therefore reduc...

Stings from bees and wasps can cause systemic allergic reactions in sensitized patients. However, the mystery of why some cases develop allergic reactions while others do not, remains poorly understood. We investigated whether particular human leukocyte antigen (HLA) class I and class II genes contribute to the development of venom allergy. A total of 21 bee and/or wasp venom sensitive patients...

Recent genetic studies in Drosophila and mouse have uncovered a new aspect of the Wnt signal transduction machinery. Mutations disrupting LDL-receptor related proteins produce loss-of-function Wnt phenotypes, suggesting that these cell surface molecules may represent essential co-receptors for Wnt ligands.

Unmanned aerial vehicles (UAVs) performing their operations for a long time have been attracting much attention in military and civil aviation industries for the past decade. The applicable field of UAV is changing from the military purpose only to the civil one. Because of their low operation cost, high reliability and the necessity of various application areas, numerous development programs h...

Aicardi-Goutieres syndrome is a familial progressive early onset encephalopathy with basal ganglia calcifications, chronic CSF lymphocytosis and high level of interferon-alpha in CSF. Cutaneous necrotic lesions and the neuropathological aspect of microangiopathy and microinfarctions suggest a vascular process in relation to elevated interferon-alpha. A genetic defect in the regulation of its sy...

With the emerging concept of model transformation, information can be extracted from one or more source models to produce the target models. The conversion of these models can be done automatically with specific transformation languages. This conversion requires mapping between both models with the help of dynamic hash tables. Hash tables store reference links between the elements of the source...
