Measuring changes in tumor volume using anatomical imaging weeks to months post radiation therapy (RT) is currently the clinical standard for indicating treatment response to RT. For patients whose tumors do not respond successfully to treatment, this approach is suboptimal as timely modification of the treatment approach may lead to better clinical outcomes. We propose to use tumor microvascul...

The paper presents a new Formal Description Technique , RT-LOTOS (Real-Time LOTOS) which is a temporal extension of the standard Formal Description Technique LOTOS. After a brief and informal introduction to RT-LOTOS, the paper describes a design method of multimedia protocols based on the use of generic and reusable RT-LOTOS speciication building blocks. An application in the area of multimedi...

In large scale distributed systems, replication is a popular technique for improving the accessibility of information and surviving the unreliability of communication networks. Pessimistic replication and optimistic replication are two contrasting replication models. They represent the two extremes in the availability-consistency. Pessimistic replication favors consistency over availability, wh...

introduction: hospitals performance indicators will help monitoring, evaluation and decision making and therefore must be selected and ranked accurately. the aim of present study is identifying and selecting key hospitals performance indicators. materials and methods: this is a descriptive and mixed (quantitative-qualitative) study. literature review and expert panel has been done to identify a...

background: bordetella pertussis is the causative agent of pertussis. in brazil, laboratory diagnosis of pertussis is based on the culture. in 2010, was standardized the real-time pcr taqman® in routine diagnosis. objectives: the aim of this study was to evaluate the impact achieved with the introduction of rt-pcr for the routine diagnosis of pertussis and to compare with the results obtained f...

Variable traffic conditions cause travel time uncertainty and further lead to time-varying accessibility. Most current studies do not fully consider fluctuations in accessibility use complicated methods that likely overestimate the level of hinder application measures. To address this issue, we utilized large-scale open-source data proposed an interpretation reliability concept incorporates rel...

in this paper, size distribution of nano-bubbles was measured by the reliable and fast method of laserdiffraction technique. nano-bubbles were produced using a nano-bubble generator designed and madebased on hydrodynamic cavitation phenomenon in venturi tubes. a central composite design withresponse surface methodology was used to conduct a five factor, five level factorial experimental designo...
