PURPOSE Energy-resolved CT has the potential to improve the contrast-to-noise ratio (CNR) through optimal weighting of photons detected in energy bins. In general, optimal weighting gives higher weight to the lower energy photons that contain the most contrast information. However, low-energy photons are generally most corrupted by scatter and spectrum tailing, an effect caused by the limited e...

Online trust is important in both business-to-business and business-to-consumer e-business. This paper focuses on the impact of trust in online retailing (e-tailing). Based on a review of selected studies, we articulate a conceptual framework of trust in e-tailing including its antecedents, and consequences, and propose some promising future research avenues in online trust. This paper will hel...

Although a growing body of research is developing to address the different e-business practices in the electronic marketplace, e-tailing strategies have only been investigated as part of the study of general e-business strategies. However, researchers recognise that innovative and unique modes of e-tailing operations have emerged in recent years. Therefore, this paper introduces an organising f...

Heavy metal pollutions of soil is one of the serious problems in the mining tailing areas, therefore, it is significant to estimate heavy metal of soil in the mining tailing areas. This research take Jinduicheng Mo mining tailings, Huaxian, Shaanxi Province as the study area. A total number of 288 soil samples collected at the mining tailing areas. And the heavy metal concentrations of Pb in so...

The behaviour of adenine and 2’-deoxyadenosine-5’-monophosphate (dAMP) at positive surface potentials of a silver working electrode was investigated using surface-enhanced Raman scattering (SERS). The use of positive potentials in the presence of adenine or dAMP leads to a rapid accumulation of an intense spectrum. It is proposed that complexes of adenine (dAMP) with silver generate the observe...

Tailing of DNA with terminal transferase is a technically demanding, but essential step in full-length cDNA cloning procedures*•^. It is also an essential step of a poly(dA) affinity labelling technique, which has been used to select families of partial restriction fragments on oligo(dT)cellulose^•*. In order to bypass the need for transferase in the latter technique, we made a simple modificat...

Rare earth mine tailing dumps are environmental hazards because tailing easily leaches and erodes by water and wind. To assess the influence of mine tailing on the geochemical behavior of rare earth elements (REEs) in soil, sixty-seven surface soil samples and three soil profile samples were collected from different locations near China's largest rare earth mine tailing. The total concentration...

Non-specific tail sequences are often added to the 5'-terminus of primers to improve the robustness and overall performance of diagnostic assays. Despite the widespread use of tailed primers, the underlying working mechanism is not well understood. To address this problem, we conducted a detailed in vitro and in silico analysis of the enhancing effect of primer tailing on 2 well-established foo...

AIMS To analyse the contribution of certain social, familial, prenatal, perinatal, and developmental background factors in the pathogenesis of deficits in attention, motor control, and perception (DAMP). METHODS A population based case-control study was carried out with 113 children aged 6 years, 62 diagnosed with DAMP and 51 controls without DAMP. The children's health and medical records we...
