Requirements models and specifications tend to be plagued by many problems such as requirements that have been abandoned and that are no longer meaningful, descriptions that are unnecessarily long and convoluted, and information that is duplicated. These problems hinder the overall understandability and reusability of software models throughout the whole(More)
Tropos is a framework which offers an approach to guide the development of multi-agent systems (MAS). It relies on the i* notation to describe both requirements and architectural design. However, the use of i* as an architectural description language (ADL) is not suitable, since it presents some limitations to capture all the information required for(More)
Lipid metabolism plays an essential role in carcinogenesis due to the requirements of tumoral cells to sustain increased structural, energetic and biosynthetic precursor demands for cell proliferation. We investigated the association between expression of lipid metabolism-related genes and clinical outcome in intermediate-stage colon cancer patients with(More)
Currently problems caused by the high demand for imaging studies require the application of methods to improve quality and ensure that resources have optimal impact on the health and welfare of the population. SDSRI (Storage and Display System of Radiological Imaging) is a minimal system PACS (Picture Ar-chiving Communication System), which was developed at(More)
Payers are a major stakeholder in any considerations and initiatives concerning adaptive licensing of new medicinal products, also referred to as Medicines Adaptive Pathways to patients (MAPPs). Firstly, the scope and necessity of MAPPs need further scrutiny, especially with regard to the definition of unmet need. Conditional approval pathways already exist(More)
Pulmonary nodules (PN), frequently found on imaging studies, represent a diagnostic challenge during the follow up of cancer patients. However, published data about investigation of PNs incidentally found on chest imaging is scarce. The PN may be present at the time of cancer diagnosis, or arise during the treatment or follow-up periods. In the context of(More)
The High Performance Computing has achieved a high level in terms of processing capacity at reduced cost using Graphics Processing Units to perform algorithms of high computing cost. The massively parallel systems based on GPU have to deal with hundreds of processing cores embedded in a single chip, leading to exceptional computing gains. The CUDA(More)
