New Encodings of Pseudo-Boolean Constraints into CNF
2009
International audience; This paper answers affirmatively the open question of the existence of a polynomial size CNF encoding of pseudo-Boolean (PB) constraints such that generalized arc consistency (GAC) is maintained through unit propagation (UP). All previous encodings of PB constraints either did not allow UP to maintain GAC, or were of exponential size in the worst case. This paper presents an encoding that realizes both of the desired properties. From a theoretical point of view, this narrows the gap between the expressive power of clauses and the one of pseudo-Boolean constraints.
Editor's Choice – Follow-up of Patients After Revascularisation for Peripheral Arterial Diseases: A Consensus Document From the European Society of C…
2019
International audience; Peripheral arterial diseases comprise different clinical presentations, from cerebrovascular disease down to lower extremity artery disease, from subclinical to disabling symptoms and events. According to clinical presentation, the patient's general condition, anatomical location and extension of lesions, revascularisation may be needed in addition to best medical treatment. The 2017 European Society of Cardiology guidelines in collaboration with the European Society for Vascular Surgery have addressed the indications for revascularisation. While most cases are amenable to either endovascular or surgical revascularisation, maintaining long-term patency is often chall…

Power struggle, submission and partnership: Agency constructions of mothers of children with ADHD diagnosis in their narrated school involvement
2014
The contemporary education paradigm highlights the interdependency of home and school expertise. This discourse analysis study examines the narrated agentive possibilities of 18 Finnish mothers of children diagnosed with ADHD to influence and be involved in their child's schooling. Mothers' strong involvement endeavor is premised on their expertise concerning ADHD, distrust of teachers' adequate knowledge of and attitude towards their child, and anxiety for their child's wellbeing. However, our analysis reveals a gap between the mothers' narrated potential agency to fight for her child's well-being and their actual capability to be involved as intended, due to unequal institutional power re…
Unravelling the moderating effects of size and experience on product innovations and exports: a study in a medium knowledge-intensive industry
2012
This paper contributes to improve our knowledge on the important role of product innovation in export strategy by introducing the moderating effects of organizational variables. We argue that in a medium knowledge-intensive industry, these variables might strengthen the relationship between innovations and exports. Research on innovation and export strategy has addressed these issues increasingly during last decades; however, the divergence on the empirical approaches difficult the understanding of the linkages among variables, which are highly dependent on the industry technological characteristics. We carry out a time-lagged study using the literature-based innovation output (LBIO) method…

Asymmetric behaviour of biotechnology business patterns in Spain
2009
Since the end of the 90s there has been an increase in the emergence of biotechnology industries in Spain, partially as a result of growing support from institutionally based infrastructures. Through the use of empirical fieldwork, this study aims to reveal how future prospects are not as optimistic as most Spanish agents perceive. Our conclusions are based on the asymmetric behaviour shown by Spanish biotechnology firms in their business models. This asymmetry is based on the overwhelming dominance of business models centred on low investment, limited R&D expenditure and minor or incremental innovation, whereas the long term–long return model, which prevails in the leading countries in thi…
Determination of Pareto frontier in multi-objective maintenance optimization
2011
Abstract The objective of a maintenance policy generally is the global maintenance cost minimization that involves not only the direct costs for both the maintenance actions and the spare parts, but also those ones due to the system stop for preventive maintenance and the downtime for failure. For some operating systems, the failure event can be dangerous so that they are asked to operate assuring a very high reliability level between two consecutive fixed stops. The present paper attempts to individuate the set of elements on which performing maintenance actions so that the system can assure the required reliability level until the next fixed stop for maintenance, minimizing both the globa…
Adapting RRI public engagement indicators to the Spanish scientific and innovation context: a participatory methodology based on AHP and content anal…
2022
The paradigm proposed by Responsible Research and Innovation in the European Commission policy discourse identifies Public Engagement as a key area for exchange and dialogue among multiple actors following an inclusive and participatory process. Two definite set of indicators have already arisen at European level to monitor Public Engagement activities in the Science and Innovation realm. Our study aims to propose a deliberative participatory process, which involves selected stakeholders, for the adaptation of the European indicators to the specific Spanish scientific and innovation context. The methodological procedure is of exploratory nature and will be based in a combination of, on the …
A survey on IVIVC/IVIVR development in the pharmaceutical industry – Past experience and current perspectives
2017
The present work aimed to describe the current status of IVIVC/IVIVR development in the pharmaceutical industry, focusing on the use and perception of specific approaches as well as successful and failed case studies. Two questionnaires have been distributed to 13 EFPIA partners of the Oral Biopharmaceutics Tools Initiative and to the Pharmacokinetics Working Party of the European Medicines Agency in order to capture the perspectives and experiences of industry scientists and agency members, respectively. Responses from ten companies and three European Agencies were received between May 21st 2014 and January 19th 2016. The majority of the companies acknowledged the importance of IVIVC/IVIVR…
