BACKGROUND AND PURPOSE To compare partial-breast clinical target volumes generated using a standard 15 mm margin (CTV(standard)) with those generated using three-dimensional surgical excision margins (CTV(tailored 30)) in women who have undergone wide local excision (WLE) for breast cancer. MATERIAL AND METHODS Thirty-five women underwent WLE with placement of clips in the anterior, deep and ...

Objectives To investigate the attributes of Australian clinical quality registries (CQR). Design and setting Survey of 40 CQRs between September 2015 and April 2016. Participants CQR lead investigators/project managers. Intervention None. Main outcome measures Registry organization, geographical coverage, data quality, management, characteristics, output and outcomes. Results Of those...

Measuring how much cybercrime exists is typically done by first defining cybercrime and then quantifying how many cases fit that definition. The drawback is that definitions vary across countries and many cybercrimes are recorded as traditional crimes. An alternative is to keep traditional definitions of crime and quantify the amount of associated information and communication technologies (ICT...

This paper develops a comprehensive new approach to the modeling and analysis of heterogeneous cellular networks (HetNets) that accurately incorporates correlation in the locations of users and base stations, which exists due to the deployment of small cell base stations (SBSs) at the places of high user density (termed user hotspots in this paper). Modeling the locations of the geographical ce...

Natural History Collections (NHCs) play a central role as sources of data for biodiversity and conservation. Yet, few NHCs have examined whether the data they contain is adequately representative of local biodiversity. I examined over 15,000 databased records of Hymenoptera from 1435 locations across New Zealand collected over the past 90 years. These records are assessed in terms of their geog...

Abstract Researchers in science and engineering have a long tradition of collaboration, and increasingly carry out these collaborations across geographical distance. Similar trends exist in industry, where virtual teams are increasing in frequency. While we know that such dispersed collaborations are difficult, there is growing evidence of success. The physical and biological sciences have led ...

BACKGROUND The Strategic Advisory Group of Experts on Immunization (SAGE) has recommended introduction of at least 1 dose of inactivated poliovirus vaccine (IPV) at ≥14 weeks of age through the routine immunization program in countries currently not using IPV. METHODS We analyzed all available unrestricted data obtained from the Demographic and Health Surveys since 2005 in sub-Saharan Africa ...

Theme parks can be modeled as geographical areas where large crowds of people move among different attractions. The operators of a theme park are interested in quickly and efficiently handling events occurring at various locations in the park. We propose a model which deploys a wireless network with mobile sinks to facilitate event coverage. The event coverage problem can be divided into two su...
