Large ecological data matrices may be incomplete for various reasons, preventing the use of standard multidimensional scaling (ordination) and cluster analysis packages. Although there exist a few resemblance functions that allow missing scores, is no theoretical background software support most distance similarity coefficients potentially applied in multivariate analysis. We provide general fr...

Batesian mimicry evolves when the 'umbrella' of protection provided by resemblance to a conspicuous unpalatable model species is sufficient to overcome increased predation risk associated with greater conspicuousness. However, the shape and extent of this umbrella, that is, how the level of protection provided by mimicry changes with degree of resemblance between model and mimic, is poorly know...

This paper takes into account the Wittgenstein’s idea of family resemblance as a particular crisp relation between some fuzzy sets, that is, between some representations of predicates use from its use. It is shown that all uses of the same predicate actually do have some kind of family resemblance, that some pairs of predicates cannot, and how the predicates migration between different universe...

tent of twin resemblance by means of a number of mental and physical measurements. Since that time, a growing realization of the importance of studying twin resemblance to determine the relative influence of heredity and environment, has led a large number of investigators to turn their attention to this problem. Rexroad,3 in a recent article, has assembled the results of fifty-seven studies of...

background: premature ovarian failure (pof) is a disorder of multi causal etiology. autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in pof. the aim of this study was to identify the level of auto-antibodies in pof and familial pof patients. materials and methods: in this study, auto-antibodies including anti-ovarian antibody (aoa), a...

Familial Mediterranean fever, an autosomal recessive disorder, is a member of the periodic fever syndromes, and considered to be the most common cause of recurrent febrile episodes in children. It is important to understand the disorder as familial Mediterranean fever falls on a spectrum of various presentations; the recurrent episodes of familial Mediterranean fever may be so severe that the q...

The mathematical concept of document resemblance captures well the informal notion of syntactic similarity. The resemblance can be estimated using a fixed size “sketch” for each document. For a large collection of documents (say hundreds of millions) the size of this sketch is of the order of a few hundred bytes per document. However, for efficient large scale web indexing it is not necessary t...
