Different toxoplasma antigens were entrapped within liposomes and evaluated, in this form, for their ability to protect Swiss mice against toxoplasma infection: soluble tachyzoite antigen (L/TAg), tissue cyst (L/CAg), tachyzoite plus tissue cyst (L/TCAg) or purified antigen of tachyzoite (L/pTAg). The protein used in L/pTAg was purified from tachyzoites using a stage-specific monoclonal antibod...

The RNA binding protein FCA regulates the floral transition and is required for silencing RNAs corresponding to specific noncoding sequences in the Arabidopsis thaliana genome. Through interaction with the canonical RNA 3' processing machinery, FCA affects alternative polyadenylation of many transcripts, including antisense RNAs at the locus encoding the floral repressor FLC. This potential for...

Formal concept analysis (FCA) is a branch of applied mathematics with roots in lattice theory (Wille, 1982; Ganter & Wille, 1999). It deals with the notion of a concept in a given universe, which it calls context. For example, consider the context of transactions at a grocery store where each transaction consists of the items bought together. A concept here is a pair of two sets (A, B). A is th...

Supplementation with lipopolysaccharide (LPS) from non-pathogenic Escherichia coli was found to enhance the adjuvant effects of a veterinary vaccine adjuvant (ISA 71VG®). Sperm immunization using 71VG as an adjuvant in the immature period induced infertility in 25% of male rats, whereas this increased to 62.5% after immunization with 71VG + LPS or Freund's complete adjuvant (FCA). Mean testicul...

Formal Concept Analysis (FCA) is a mathematical theory which tries to structure and formalise conceptual thinking. The main research interest presented by this paper is to use it in the very first steps of system analysis. Most of the wellknown methods for object oriented analysis share a common lack: They do not suggest suitable guidelines for the identification of the objects and classes with...

BACKGROUND The goal of ontology matching is to identify correspondences between entities from different yet overlapping ontologies so as to facilitate semantic integration, reuse and interoperability. 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 ...

RESUME. Ce papier présente une nouvelle approche de recherche en continue des K plus proches voisins (C-KNN). Notre approche, qui s'applique sur des réseaux routiers, adopte l’Analyse Formelle de Concepts (FCA : Formel Concept Analysis) qui est un paradigme à base de fondement mathématique. FCA permettra de présenter une abstraction du réseau qui se base sur les voisinages. L’approche proposée ...

A straightforward mapping from Conceptual Graphs (CGs) to Formal Concept Analysis (FCA) is presented. It is shown that the benefits of FCA can be added to those of CGs, in, for example, formally reasoning about a system design. In the mapping, a formal attribute in FCA is formed by combining a CG source concept with its relation. The corresponding formal object in FCA is the corresponding CG ta...

OBJECTIVE In response to an acute shortage of clinical fieldwork placement opportunities, faculty members of the Department of Occupational Therapy at Tel Aviv University in Israel formulated the Fieldwork Centers Approach (FCA) as an alternative approach to fieldwork education. Under the FCA, groups of two to eight students were assigned to one facility. The number of participating supervisors...

We discuss the background and methods for estimating uncertainty in establishing a regional, terrestrial biota Full Carbon Account (FCA) in a holistic manner utilizing our experiences in generating such an account for a vast region in Northern Eurasia. For such an analysis, it is important to (1) provide a full account; (2) consider the relevance of a certified account; (3) understand that any ...
