A multivariate analysis of dominance inDrosophila

Theoretical and Applied Genetics, 1975
Eleven wing measurements in twoDrosophila melanogaster lines (Canton and FLL) and their reciprocal crosses were analyzed by a multivariate technique in order to investigate changes in variability when dominance is manifested. FLL line was obtained by artificial selection for short wing applied on one measurement on the rightwing.

Microeconomic analysis using dominant relationship analysis

Knowledge and Information Systems, 2011
The concept of dominance has recently attracted much interest in the context of skyline computation. Given an N-dimensional data set S, a point p is said to dominate q if p is better than q in at least one dimension and equal to or better than it in the remaining dimensions.

Prospective Analysis of Falls in Dominant Ataxias

European Neurology, 2012
In a previous retrospective study, we demonstrated that falls are common and often injurious in dominant spinocerebellar ataxias (SCAs) and that nonataxia features play an important role in these falls. Retrospective surveys are plagued by recall bias for the presence and details of prior falls.

Dominance analysis of irreducible CFGs by reduction

ACM SIGPLAN Notices, 2005
This paper presents a simple and fast algorithm with proof of correctness for analyzing dominance relations of control flow graphs (CFGs). A dominator tree and dominance frontiers are obtained by reducing a DAG, which is obtained by adding dummy vertexes to the original CFG to transmit dominance relation of irreducible loops to the ...

Analysis of dominant spring mutations in rye

Russian Journal of Genetics, 2006
The dominant mutant genes responsible for the spring habit were studied in seven rye plants according to the developed scheme of two-step crosses and analysis of the F2 progeny. The genotypes with a particular genetic formula (heterozygote) were obtained by crossing the studied plants with the winter rye Korotkostebel'naya 69 carrying the recessive ...

Dominance relationship analysis with budget constraints

Knowledge and Information Systems, 2013
Creating a new product that dominates all its competitors is one of the main objectives in marketing. Nevertheless, this might not be feasible since in practice the development process is confined by some constraints, e.g., limited funding or low target selling price.

Dominance network analysis of economic efficiency

Expert Systems with Applications, 2017
A dominance network can be built based on the observed input and output data.Two types of dominance relationships are considered: technical and economic.Complex networks analysis can be performed on this layered, weighted, directed network.Technical, profit and allocative inefficiencies can be computed.Profit inefficiency relation has an underlying ...

A Temporal Dominant Relationship Analysis Method

2008
Recent research on skyline queries has attracted much interest in the database and data mining community. The concept of dominant relationship analysis has commonly used in the context of skyline computation, due to its importance in many applications. Current methods have only considered so-called min/max hard attributes like price and quality which a

Dominance behavior: A phylogenetic analysis in the mouse

Physiology & Behavior, 1975
Tube-dominance behavior differed significantly in C57BL/6By and BALB/cBy mice. Evaluation of these two inbred strains, and their recently developed recombinant inbred strains permitted the derivation of an hypothesis regarding possible genetic control of this behavior in mice.

Stochastic Dominance Analysis of iShares [PDF]

The European Journal of Finance, 2007
Abstract Country indices as represented by iShares exhibit non-normal return distributions with both skewness and kurtosis. Earlier studies provide procedures for determining the statistical significance of stochastic dominance measures and the Sharpe Ratio.
