Data Mining(also known as Knowledge Discovery) is defined as the non-trivial extraction of implicit, previously unknown, and potentially useful information from data. It includes not only methods for extracting information from the given data, but also visualizing the information. Formal Concept Analysis(FCA) is one of Data mining research fields, and it has been applied to a number of areas su...

This paper discusses in how far FCA software can be combined with the computer algebra system Sage. The motivation for this paper is teaching mathematics to software engineering students using Sage and FCA which highlights differences and connections between mathematical and computational structures. Furthermore, this paper provides implementation details on how Sage’s functions for matrices, g...

Query-directed browsing of unstructured Web-texts using Formal Concept Analysis (FCA) confronts two problems. Firstly on-line Web-data is sometimes unstructured and any FCA-system must include additional mechanisms to structure input sources. Secondly many online collections are large and dynamic so a Web-robot must be used to automatically extract data. These issues are addressed in this paper...

This paper discusses FCA software interoperability from a variety of angles: because the central FCA structures, formal contexts and concept lattices, can be represented in non-FCA software, interoperability with such software is of relevance. The non-FCA software in question is spreadsheet, relational database, graph and vector graphics software. The simplest approach to interoperability consi...

and controls the expression of a floral repressor, FLOWERING LOCUS C (FLC) (Michaels and Amasino, 1999; Sheldon et al., 1999), which modulates the activity of the other two pathways (Mouradov et al., 2002; Simpson and Dean, 2002).

Ambient temperature fluctuates diurnally and seasonally. It profoundly influences the timing of flowering in plants. The floral integrator FLOWERING LOCUS T (FT) mediates ambient temperature signals via the thermosensory pathway in Arabidopsis flowering. microRNA172 (miR172), which promotes flowering by inducing FT, also responds to changes in ambient temperature. However, it is largely unknown...

BACKGROUND Low fractional calcium absorption (FCA) contributes to osteoporosis but is not measured clinically, as the gold-standard method requires administration of two calcium tracers and a subsequent 24-h urine collection. We evaluated alternate methods to measure FCA, compared to the gold standard method. METHODS We administered two stable calcium isotope tracers (~8 mg oral (44)Ca and ~3...

The civil False Claims Act (FCA) imposes harsh penalties against parties who misappropriate federal funds. The statute's qui tam whistle-blower provisions create strong financial incentives for private individuals to bring and pursue FCA cases against health providers on the government's behalf--even where government attorneys decline to intervene. FCA cases where the government declined to int...

The genes controlling the timing of the transition from vegetative to reproductive growth are likely candidates for regulators of genes initiating floral development. We have investigated the interaction of one particular gene controlling flowering time, FCA, with the meristem identity-genes TERMINAL FLOWER 1 (TFL1), APETALA 1 (AP1) and LEAFY (LFY) and the floral repression gene EMBRYONIC FLOWE...

INTRODUCTION For emergency department (ED) patients, delays in care are associated with decreased satisfaction. Our department focused on implementing a front-end vertical patient flow model aimed to decrease delays in care, especially care initiation. The physical space for this new model was termed the Flexible Care Area (FCA). The purpose of this study was to quantify the impact of this inte...
