BACKGROUND Cerebral arteriopathies, including an idiopathic focal cerebral arteriopathy of childhood (FCA), are common in children with arterial ischemic stroke and strongly predictive of recurrence. To better understand these lesions, we measured predictors of arteriopathy within a large international series of children with arterial ischemic stroke. METHODS AND RESULTS Between January 2003 ...

Knowledge Space Theory (KST) links in several ways to Formal Concept Analysis (FCA). Recently, the probabilistic and statistical aspects of KST have been further developed by several authors. We review part of the recent results, and describe some of the open problems. The question of whether the outcomes can be useful in FCA remains to be investigated.

This paper develops some existing ideas in FCA to provide an analysis of a large data set of mouse embryo gene expressions. It develops new techniques for managing complexity and visualisation in FCA to identify and approximate large groups of co-expressed genes. This work has been carried out as part the European CUBIST Project: http://www.cubist-project.eu/

Research on variability in software artefacts is something which is already studied extensively in research. The visualisation of variability is one aspect of this research, and results like e.g. feature diagrams are well-known and well-spread. When it concerns the origin of the variability within the phase of requirements engineering, research is much scarcer. A visualisation technique for bot...

As a well developed mathematical model for analyzing individuals and structuring concepts, Formal Concept Analysis (FCA) has been applied to ontology matching (OM) tasks since the beginning of OM research, whereas ontological knowledge exploited in FCA-based methods is limited. The study in this paper aims to empowering FCA with as much as ontological knowledge as possible for identifying and v...

In this dissertation we address a stochastic air traffic flow management problem. This problem arises when airspace congestion is predicted, usually because of a weather disturbance, so that the number of flights passing through a volume of airspace (flow constrained area – FCA) must be reduced. We formulate an optimization model for the assignment of dispositions to flights whose preferred fli...

The recent advances in Formal Concept Analysis (FCA) together with the major changes faced by modern Information Retrieval (IR) provide new unprecedented challenges and opportunities for FCA-based IR applications. The main advantage of FCA for IR is the possibility of creating a conceptual representation of a given document collection in the form of a document lattice, which may be used both to...

Polyadenylation factor CLP1 is essential for mRNA 3'-end processing in yeast and mammals. The Arabidopsis (Arabidopsis thaliana) CLP1-SIMILAR PROTEIN3 (CLPS3) is an ortholog of human hCLP1. CLPS3 was previously found to be a subunit in the affinity-purified PCFS4-TAP (tandem affinity purification) complex involved in the alternative polyadenylation of FCA and flowering time control in Arabidops...
