BACKGROUND Diagnostic subtraction radiography (DSR) is a new digital radiographic image subtraction method designed to enhance detection of crestal or periapical bone density changes and to help evaluate caries progression in teeth. In this clinical study, the performance of the DSR method was evaluated for its ability to detect periodontal bone loss and was compared with that of conventional e...

This paper describes a simulation based performance analysis of DSR on the basis of comparison between 802.11 and CSMA protocols. Dynamic Source Routing protocol (DSR) provides simple and efficient routing for multihop ad-hoc network of mobile nodes. It utilises a specially designed framework which builds on the Global Mobile Information System Simulator (GloMoSim). Some optimizations of DSR ha...

Routing is a challenging issue in Mobile Ad hoc Network to pass the data packets through intermediate hops in an efficient manner. In this paper, Reactive routing protocols namely AODV and DSR are evaluated under the feasible placement and random placement models. Simulation results shows that AODV and DSR are performing better in feasible placement approach comparative to the existing random p...

Purpose: The purpose of this study is to explore the roles tourists’ perceived destination social responsibility (DSR) in predicting trust and relationship continuity by utilizing multidimensional versus unidimensional construct DSR.
 Design/methodology/approach: This develops two-stage model; a first-stage model includes constructs DSR, second-stage an integrated DSR. Modern cultural heri...

The YTH domain-containing protein Mmi1, together with other factors, constitutes the machinery used to selectively remove meiosis-specific mRNA during the vegetative growth of fission yeast. Mmi1 directs meiotic mRNAs to the nuclear exosome for degradation by recognizing their DSR (determinant of selective removal) motif. Here, we present the crystal structure of the Mmi1 YTH domain in the apo ...
