In this issue of the journal, Moradi et al., have demonstrated that in Kurdistan Province of Iran individuals in lower socio-economic groups are more likely to have several risk factors for non-communicable diseases, including insufficient consumption of fruit and vegetables, insufficient consumption of fish, high consumption of unhealthy fat and oils, and hypertension. Moradi et al.’s study wa...

We present some explicit constructions of universal R-trees with applications to the asymptotic geometry of hyperbolic spaces. In particular, we show that any asymptotic cone of a complete simply connected manifold of negative curvature is a complete homogeneous R-tree with the valency 20 at every point. It implies that all these asymptotic cones are isometric depending neither on a manifold no...

Spatial data in CAD/CAM and geographic information systems involve arbitrarily-shaped 2and 3-dimensional geometries. Queries on such complex geometry data involve identification of data geometries that interact with a specified query geometry. Since geometry-geometry comparisons are expensive due to the large sizes of the data geometries, spatial engines avoid unnecessary comparisons by first c...

abstract objective : the policy makers and social managers need some criteria for building up the appropriate health status of the community and observe the equity and equality on it. they have to know the burden of diseases as a main determining factor for decision making, planning and programming. disability adjusted life years (dalys) is a criteria which shows the wasted life time due to ear...

We scrutinise the evolution of classic R-trees, particularly of the PR-tree, which is the first R-tree variant to answer range-queries in worst-case optimal runtime performance. Moreover we analyse the query dependencies of classic R-tree variants and how bulk-loading can be utilised to increase the chance of a more efficient query time. We elaborate on the influence of different input arrangem...

Macrodystrophia lipomatosa is a rare congenital form of localized gigantism characterized by an increase in all mesenchymal elements, particularly fibroadipose tissue. MR imaging can be used to examine the soft tissue and detect the fibrous and fatty hypertrophy that characterizes this condition and also diagnose an associated fibrolipomatous hamartoma of the median or plantar nerve. We des...

The K-Closest-Pairs Query (K-CPQ), a type of distance join in spatial databases, discovers the K pairs of objects formed from two different datasets with the K smallest distances. Recently, branch-and-bound algorithms based on R-trees have been developed in order to answer K-CPQs efficiently. For query optimization purposes, analytical models are needed to estimate the processing cost of a spec...

In this paper, we experimentally evaluate the relative performance of 3 external memory query structures. The R and Priority R (PR) Trees are compared using 4-sided rectangle queries in R. For 3-sided point queries in R, we compare the two structures mentioned above to the External Priority Search (EPS) Tree. While the PR and EPS Trees possess optimal I/O bounds, they are largely theoretical wo...
