It considers the extent to which the role of the broadcast channel – traditionally the main vector via whic...
Bilateral breast cancer (BBC) poses a major challenge for oncologists because of the cryptic relationship between the two lesions. The purpose of this study was to determine the origin of the contralateral breast cancer (either dependent or independent of the index tumor). Here, we used ultra-deep whole-exome sequencing and array comparative genomic hybridization (aCGH) to study four paired sam...
Modern large-scale applications are generating staggering amounts of data. In an effort to summarize and index these data sets, databases often use bitmap indices. These indices have become widely adopted due to their dual properties of (1) being able to leverage fast bit-wise operations for query processing and (2) compressibility. Today, two pervasive bitmap compression schemes employ a varia...
One-pot synthesis of basic copper carbonate/AlOOH microspheres with hierarchical structure in the absence and presence of humic acid is presented. The synthesized microspheres are characterized by SEM, EDS, TEM, XRD, FT-IR and TGA data. The catalytic ability of these hierarchical structures has been evaluated with reduction of 4-nitrophenol to 4-aminophenol with excess amount of NaBH4 as a mode...
The BBC has a rich collection of learning resources. The Knowledge and Learning website Beta aims to unlock the learning potential of this content for its users. To this purpose, the system employs semantic web technologies to organise the available learning resources. In this paper we describe the core data model that underlies the Knowledge and Learning website Beta. The Curriculum Ontology f...
