As the volume of uncertain data increases, the cost of evaluating queries over this data will also increase. In order to scale uncertain databases to large data volumes, efficient query processing methods are needed. One of the key techniques for efficient query evaluation is indexing. Due to the nature of uncertain data and queries over this data, existing indexing solutions for precise data a...

A bstract We derive correspondences of correlation functions among dual conformal field theories in two dimensions by developing a “first order formulation” coset models. examine several examples, and the most fundamental one may be conjectural equivalence between (SL( n ) k ?SL( ? 1 )/SL( k? $$ \mathfrak{sl}(n) sl <mml:...

Environmental issues and risk have become central in socioeconomic research and policy planning in order to ensure sustainable development. As environmental risk is difficult to assess and measure, different indexes have been developed to evaluate specific aspects of such risk. Environmental risk typically involves problems generated by the consumption of energy (fuels), water shortages, disast...

condition of contour lines in topographic maps, explains more geomorphologic issues such as effective processes in the land forms found in nature. change in the curvature of the transverse profile of a valley in mountainous areas, the peak of the mountain range, also reflect the geomorphologic features and expresses the tectonic events and climate changes occurring in the region. these changes ...

Mutations at the Steel (Sl) locus produce pleiotropic effects on viability as well as hematopoiesis, pigmentation and fertility. Several homozygous viable Sl alleles have previously been shown to contain either structural alterations in mast cell growth factor (Mgf) or regulatory mutations that affect expression of the Mgf gene. More severe Sl alleles cause lethality to homozygous embryos and a...

A cross-sectional comparative study was carried out to investigate the productive and reproductive performances of different genetic groups of crossbred cows at three different farming conditions in Bangladesh. Crossbred cows (n=90) those already completed third lactations, were selected randomly from three different dairy farms (e.g. Jarip, Mullah and Nahar) located in Chittagong, Bangladesh. ...

Representation theory for the Jordanian quantum algebra Uh(sl(2)) is developed using a nonlinear relation between its generators and those of sl(2). Closed form expressions are given for the action of the generators of Uh(sl(2)) on the basis vectors of finite dimensional irreducible representations. In the tensor product of two such representations, a new basis is constructed on which the gener...
