The aim of this study was to assess the effect of toothbrushing with toothpastes having different relative dentine abrasivity (RDA) and toothbrushes having different bristles hardness on different composite resins, compomers and traditional glassionomer cements by surface roughness evaluation. All the samples were evaluated regarding the surface roughness using roughness checker (Taylor Hobson-...

Representational difference analysis (RDA) is a recently developed technique used for amplifying genetic differences between two closely related genomes. We compared RDA and a modified version of RDA to examine genomic differences between the two Vibrio cholerae serogroups that cause epidemic cholera, O1 and O139, and between the two biotypes of the O1 serogroup. With both techniques, we recove...

Fast tracking and security are important factor for data transmission in wireless communication. Retrodirective antenna(RDA) is possible for the high-speed beam tracking without any priori location information. Therefore, RDA system is appropriate technology in wireless mobile communication. Also, it is possible to improve security by making direction toward the source. In this paper, we propos...

We use the Random Dispersion Approximation (RDA) to study the Mott-Hubbard transition in the Hubbard model at half band filling. The RDA becomes exact for the Hubbard model in infinite dimensions. We implement the RDA on finite chains and employ the Lanczos exact diagonalization method in real space to calculate the ground-state energy, the average double occupancy, the charge gap, the momentum...

Recurrent Neural Networks architectures excel at processing sequences by modelling dependencies over different timescales. The recently introduced Recurrent Weighted Average (RWA) unit captures long term dependencies far better than an LSTM on several challenging tasks. The RWA achieves this by applying attention to each input and computing a weighted average over the full history of its comput...

BACKGROUND Little prospectively collected data are available comparing the dietary intake of urea cycle disorder (UCD) patients to UCD treatment guidelines or to healthy individuals. OBJECTIVE To examine the protein and calorie intakes of UCD subjects who participated in clinical trials of glycerol phenylbutyrate (GPB) and compare these data to published UCD dietary guidelines and nutritional...

of these user tasks in actual usage; this, in itself, should be a call for libraries to ask more of their library management systems and, possibly, of their own systems staff, to expose more useful data to the patron. Chapter 6 is specifically about RDA authority records, and how they are created according to the principles of FRAD. After a brief introduction to RDA and how it relates to FRAD, ...
