A new strategy for studying the genome structure and organization of natural populations is proposed on the basis of a combined analysis of linkage and linkage disequilibrium using known polymorphic markers. This strategy exploits a random sample drawn from a panmictic natural population and the open-pollinated progeny of the sample. It is established on the principle of gene transmission from ...

The symmetric equilibria of the three-locus symmetric viability model are determined and their stability analyzed. For tight linkage there may be four stable equilibria, each characterized by having one pair of complementary chromosomes in high frequencies, with all others low. For looser linkage the only stable symmetric equilibrium is that with complete linkage equilibrium. For intermediate r...

Mental retardation (MR) is one of the most frequently found major genetic disorders around the world, affecting 1-3% of the people in the general population. The recent advancement in molecular biology and cytogenetic study has made possible the identification of new genes for a variety of genetic disorders including autosomal recessive MR. Recessive genetic disorders are common in Pakistan due...

We introduce an algebra of data linkages. Data linkages are intended for modelling the states of computations in which dynamic data structures are involved. We present a simple model of computation in which states of computations are modelled as data linkages and state changes take place by means of certain actions. We describe the state changes and replies that result from performing those act...

The relationship between linkage disequilibrium (LD) and recombination fraction can be used to infer the pattern of genetic variation and evolutionary process in humans and other systems. We described a computational framework to construct a linkage-LD map from commonly used biallelic, single-nucleotide polymorphism (SNP) markers for outcrossing plants by which the decline of LD is visualized w...

Data from different agencies share data of the same individuals. Linking these datasets to identify all the records belonging to the same individuals is a crucial and challenging problem, especially given the large volumes of data. A large number of available algorithms for record linkage are prone to either time inefficiency or low-accuracy in finding matches and non-matches among the records....

disk plows are one of the most important tillage tools. two way (reversible) disk plows can perform continues plowing. so they can save time and costs and hence improve overall efficiency. in this study, a “two-way” disk plow was designed based on a λ-formed straight-line, four-bar linkage (daniel mechanism). this design contains disk and rear wheel reversing mechanism, stabilization mechanism ...

Relationship between public and private sector is becoming an increasingly important issue in management of agricultural extension services. The need for a strong linkage could be identified as the gap between desirable and current situation. In this research, the differences among current and desirable situation in six diverse dimensions was calculated. The current and desirable situation was ...

I n this study, the Regional Input- Output Structural Decomposition Analysis (I-O SDA) is used to investigate the effects of technological changes on employment in Sistan and Baluchestan Province of Iran during 2006-2011. This paper develops the SDA method to decompose the technological change from two viewpoints of supply and demand for intermediate inputs in each sector. These chan...
