A structural join evaluates structural relationship (parentchild or ancestor-descendant) between xml elements. It serves as an important computation unit in xml pattern matching, such as twig joins. There exists many work on efficient structural joins. In particular, indexes can expedite structural joins by skipping unmatchable elements. A typical use of indexes is to retrieve, for a given elem...

Selection indexes have been extensively applied in the estimation of breeding value of dairy cattle for single traits as well as for combinations of traits for selection purposes. Milestones in methodology, such as multiple-trait evaluation procedures by BLUP, (co)variance component estimation, nonlinear models, discounted gene flow, dynamic programming, and international sire evaluations, toge...

BACKGROUND We used the irradiated homograft rib cartilage as an augmentation tip support and Medpore alloplast for reconstruction of the dorsum in patients with saddle nose deformities. Thereafter, the safety and efficiency of this method was evaluated to determine if this can be a safe and efficient technique for patients with saddle nose deformities. METHODS A total of 32 patients who suffe...

The objective of this study is to assess the performance of a regional hydrological model in catchments treated as ungauged. The Catchment Resources and Soil Hydrology (CRASH) model is a daily, catchment-scale, rainfall-runoff model that has been previously regionalised for England and Wales. In this paper, the regional CRASH is evaluated in three catchments located in East Anglia – eastern Eng...

The total factor productivity (TFP) of a multiple-output multiple-input firm can be defined as the ratio of an aggregate output to an aggregate input. With this definition, index numbers that measure changes in TFP can be expressed as the ratio of an output quantity index to an input quantity index. This paper uses the term multiplicatively complete to describe TFP index numbers that are constr...

The variants of similarity queries have been widely studied in recent decade, such as k-nearest neighbors (k-NN), range query, reverse nearest neighbors (RNN), an so on. Nowadays, the reverse furthest neighbor (RFN) query is attracting more attention because of its applicability. Given an object set O and a query object q, the RFN query retrieves the objects of O, which take q as their furthest...

During the past decade, a vast number of GPS devices have produced massive amounts of data containing both time and spatial information. This poses a great challenge for traditional spatial databases. With the development of distributed cloud computing, many highperformance cloud platforms have been built, which can be used to process such spatio-temporal data. In this research, to store and pr...

Controversy exists as to whether self-reported sleep quality declines with age, despite changes in sleep being accepted as part of normal aging. This study sought to investigate age-related differences in self-reported sleep quality, after controlling for conditions that are common with age, such as psychological symptoms and increased risk of sleep-disordered breathing (SDB). The Pittsburgh Sl...

Introduction. Periodic limb movements during sleep (PLMs) is common in the elderly. When quality-of-life drops due to sleep disturbances, we speak about periodic limb movement disorder during sleep (PLMD). Another similar disorder, restless legs syndrome (RLS), is considered to be related to diabetes; RLS and PLMDs are genetically related. Our aim was to detect PLMDs in a population of diabetic...
