Relationships between physicians' characteristics and practice-setting factors and their attitude towards drug promotion
( Blackwell Publishing Ltd , 2019 , Article)Purpose This study aims to investigate relationship between attitude and belief of physicians towards drug promotion and their characteristics and practice-setting factors in Sana'a, Yemen. Methods A survey method ... -
Relationships between strategic performance measures, strategic decision-making, and organizational performance: empirical evidence from Canadian public organizations
( Taylor and Francis Ltd. , 2017 , Article)This study investigates the role of strategic performance measures (SPM) in strategic decision-making and their impact on organizational performance. Based on 143 online survey responses from senior administrators across ... -
Relative infectiousness of SARS-CoV-2 vaccine breakthrough infections, reinfections, and primary infections.
( Springer , 2022 , Article)SARS-CoV-2 breakthrough infections in vaccinated individuals and in those who had a prior infection have been observed globally, but the transmission potential of these infections is unknown. The RT-qPCR cycle threshold ... -
Relative sensitivity of soft-bottom intertidal macrofauna to increased CO2 and experimental stress
( Inter-Research , 2014 , Article)We used a controlled CO2 perturbation experiment to test hypotheses about changes in diversity, composition and structure of soft-bottom intertidal macrobenthic assemblages, under realistic and locally relevant scenarios ... -
The Relative Validity and Reproducibility of Food Frequency Questionnaires in the China Kadoorie Biobank Study
( MDPI , 2022 , Article)Background: Short versions of qualitative and quantitative food frequency questionnaires (FFQs) are widely used to assess usual food intake. However, fewer studies evaluated their relative validity and reproducibility in ... -
Relay assignment in multiple source-destination cooperative networks with limited feedback
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)We consider in this paper relay assignment for cooperative systems with mutiple source-destination pairs. The objective here is to assign relays to the source-destination pairs in such a way that all pairs achieve the ... -
Relay assignment in network-coded cooperative systems with M-PSK modulation over asymmetric channels
( IEEE , 2010 , Conference Paper)We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ... -
Relay selection for cooperative underwater acoustic communication systems
( IEEE , 2012 , Conference Paper)In this paper, we consider a multi-carrier and multi-relay underwater acoustic communication (UWAC) system and investigate the relay selection problem. Our channel model is built on an aggregation of both large-scale path ... -
Relay selection in FDD amplify-and-forward cooperative networks
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)In this paper, the problems of relay selection and distributed beamforming are investigated for bi-directional dual-hop amplify-and-forward frequency-division duplex cooperative wireless networks. When using individual ... -
Relay selection in underlay cognitive networks with fixed transmission power nodes
( John Wiley & Sons, Ltd. , 2013 , Article)Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ... -
Relay selection schemes to minimise outage in wireless powered communication networks
( Institution of Engineering and Technology , 2016 , Article)In this study, the authors discuss relay selection schemes with the objective to minimise outage probability for a network consisting of a single source, multiple relays and a single destination. The relays are powered by ... -
Relay-Assisted Primary and Secondary Transmissions in Cognitive Radio Networks
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)We assume a set of cognitive relay nodes that assists both primary and secondary transmissions in a time-slotted cognitive radio networks. To regulate the channel access of the various nodes in the network, we propose an ... -
Release of colloids in saturated porous media under transient hydro-chemical conditions: A pore-scale study
( Elsevier , 2021 , Article)The deposition and consequent release of colloids pose a significant challenge to the environment, groundwater quality and human health. Subsurface soil contains numerous types of colloids that exhibit a diverse range of ... -
Release-time aware VM placement
( IEEE , 2014 , Conference Paper)Consolidating virtual machines (VMs) on as few physical machines (PMs) as possible so as to turn into sleep as many PMs as possible can make significant energy savings in cloud centers. Although traditional online bin ... -
Relevance of lifecycle management to smart city development
( Inderscience Publishers , 2018 , Article)Smart cities are complex ecosystems with interrelated systems or system of systems. Hence, management of smart cities is very important due to the big number of stakeholders, diversity of application domains, heterogeneity ... -
Reliability and criterion-related validity of a new repeated agility test
( Institute of Sport National Research Institute , 2016 , Article)The study aimed to assess the reliability and the criterion-related validity of a new repeated sprint T-test (RSTT) that includes intense multidirectional intermittent efforts. The RSTT consisted of 7 maximal repeated ... -
Reliability and validity of a modified Illinois change-of-direction test with ball dribbling speed in young soccer players
( Institute of Sport , 2022 , Article)The purpose of this study was to assess test-retest reliability, discriminative and criterion-related validity of the modified Illinois change-of-direction (CoD) test with ball dribbling-speed (ICODT-BALL) in young soccer ... -
Reliability estimation of load sharing capacity-c-out-of-n pairs:G Balanced system
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In many cases, systems are required to provide a specified capacity such as the case of power distribution system. A system fails when its capacity does not meet the required minimum capacity. In this paper, we investigate ... -
Reliability of narrative assessment data on communication skills in a summative OSCE
( Elsevier Ireland Ltd , 2019 , Article)Objective: To quantitatively estimate the reliability of narrative assessment data regarding student communication skills obtained from a summative OSCE and to compare reliability to that of communication scores obtained ... -
Reliability-aware service provisioning in NFV-enabled enterprise datacenter networks
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Network Function Visualization (NFV) enables the complete decoupling of Network Functions (NFs) (e.g., firewall, intrusion detection, routing, etc.) from physical middleboxes used to implement service-specific and strictly ...
