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 ...

In this paper, we compare the conventional Network Speech Recognition (NSR) and the newly established Distributed Speech Recognition (DSR) concepts for mobile communications. These implementation approaches to Automatic Speech Recognition (ASR) are analyzed from three aspects. First, the effect on the speech recognition accuracy of ASR systems with various complexity. Second, usability in diffe...

Genetic diversity and community structure of sulfate-reducing bacteria was investigated down the 12 meter water column of Siders Pond, a meromictic salt pond in Falmouth, MA. The physical and chemical gradients down this water column were also investigated, as they provide distinct niches for the microorganisms of Siders Pond. Microbial DNA was extracted from water samples at 12 depths. The dis...

INTRODUCTION Delayed splenic rupture (DSR) is an unusual outcome following blunt abdominal trauma. Although DSR is defined as bleeding more than 48 hours after blunt trauma in a previously hemodynamically stable patient, a review of the reported cases in the literature shows that in almost all of the cases the initial CT imaging revealed some form of damage to the spleen. CASE PRESENTATION He...

Physiological sources of variation in the 2H-to-18O dilution space ratio (DSR) were examined in 34 males and 20 females (4-78 yr; 14.7-143.2 kg; 1.8-61.0% body fat). Dilution spaces were obtained by time 0 extrapolation of isotope washout over 10-14 days, and body composition was obtained by underwater weight (adults) or bioelectrical impedance (children). The mean DSR was 1.050 +/- 0.015 (rang...
