BACKGROUND/AIMS Non-concordance has often been reported as a major contributor to the failure of occlusion therapy for amblyopia. In other fields of medicine the extent of a patient's understanding in areas of the disease and treatment has been shown to have both a direct and indirect effect on subsequent concordance. The aims of this study were to determine the extent of parental non-concordan...

We explore the consequences of a set of axioms which extend Scarsini’s axioms for bivariate measures of concordance to the multivariate case and exhibit the following results: (1) A method of extending measures of concordance from the bivariate case to arbitrarily high dimensions. (2) A formula expressing the measure of concordance of the random vectors (±X1, · · · ,±Xn) in terms of the measure...

We generalize the Manolescu-Owens smooth concordance invariant δ(K) of knots K ⊂ S to invariants δpn(K) obtained by considering covers of order p, with p a prime. Our main result shows that for any prime p 6= 2, the thus obtained homomorphism ⊕n∈Nδpn from the smooth concordance group to Z∞ has infinite rank. We also show that unlike δ, these new invariants typically are not multiples of the kno...

The notion of concordance is central to many multiple criteria techniques relying on ordinal information, e.g. outranking methods. It leads to compare alternatives by pairs on the basis of a comparison of coalitions of attributes in terms of “importance”. This note proposes a characterization of the binary relations that can be obtained using such comparisons, within a general framework for con...

We review the free parameters in the concordance cosmology, and those which might be added to this set as the quality of astrophysical data improves. Most concordance parameters encode information about otherwise unexplored aspects of high energy physics, up to the GUT scale via the “inflationary sector,” and possibly even the Planck scale in the case of dark energy. We explain how neutrino pro...

We present CoocViewer, a graphical analysis tool for the purpose of quantitative literary analysis, and demonstrate its use on a corpus of crime novels. The tool displays words, their significant co-occurrences, and contains a new visualization for significant concordances. Contexts of words and co-occurrences can be displayed. After reviewing previous research and current challenges in the new...

Introduction: Implementation of teledermatology in primary care offers the possibility of treating patients using specific dermatologic knowledge in far away places with infrequent availability to these services. It is a priority to implement teledermatology services which demonstrate diagnostic reliability and satisfaction among users. Objectives and methods: To measure the diagnostic reliabil...

We show that surgery on a connected clover (or clasper) with at least one loop preserves the concordance class of a knot. Surgery on a slightly more special class of clovers preserves invertible concordance. We also show that the converse is false. Similar results hold for clovers with at least two loops vs. S -equivalence. AMS Classi cation 57N10; 57M25
