Similarity is the key notion underlying many contemporary theories about the representation of meaning through words or concepts. However, these representations are strongly colored by the kind of information captured by various semantic measures. In this paper we present a systematic comparison of human similarity judgments and calculated similarity coefficients from different sources of seman...

Current similarity measures for virtual screening are based on the use of molecular fingerprints and the Tanimoto coefficient. This paper describes two ways in which one can increase the effectiveness of similarity-based virtual screening: using similarity coefficients other than the Tanimoto coefficient for the comparison of molecular fingerprints; and using a graph-theoretic similarity measur...

One concern about using transgenic plants is the genetic variation that occurred from theirs tissue culture and regeneration. Molecular markers are an important element for efficient and effective determination of genetic variation. The present work was carried out to assess the genetic uniformity of transgenic cottons (Bt and chitinase lines), using RAPD, ISSR molecular markers and SDS-PAGE an...

rapd markers through an application of 23 decamer primers were employed for genetic diversity analysis of some sweet cherry cultivars. bands with good resolution and high repeatability were selected for evaluations. the 23 primers produced 188 bands, among which, 153 were polymorphic. cluster analysis of the cultivars was performed based on the presence (1) and absence (0) of the bands, using j...

BACKGROUND & OBJECTIVES Coagulase negative staphylococci (CNS) are potential pathogens with the increased use of implants in hospitals. Macrolide, lincosamide and streptogramin B (MLSB) are used in the treatment of staphylococcal infections. The aim of this study was to molecular detection of inducible clindamycin resistance and genetic pattern in CNS isolates and their transmission between hos...

OBJECTIVES To examine whether people who are within 31days of stroke onset are able to produce controlled lower limb movement, and phasic activity in antagonistic lower limb muscle groups, during Upright Pedalling (UP). DESIGN Observational study. SETTING Acute stroke unit within a University Hospital. PARTICIPANTS Eight adults between 3 and 30days from stroke onset, with unilateral lower...

A study was r~ade of tile degree of similarity between pairs of Russian nouns, as expressed by their tendency to occur in sentences with identical ~,,ords in identical syntactic relationships. A similarity matrix was prepared for forty nouns; for each pair of nouns the number of shared (i) adjective dependents, (ii) noun dependents, and (iii) noun governors was automatically retrieved from mach...

Minimal sampling areas have been determined for marine Bangiophyceae and Cyanophyceae epiphytic on Cladophora prolifera and Halopteris scoparia in Calvi, Corsica. This was done by observing the stabilization of species/area curves and of qualitative and quantitative similarity coefficients between samples of increasing size. For Cyanophyceae (studied only on Cladophora) the minimal sampling are...
