    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA microarray; differential expression; gene expression; quality control QC ; quality assurance QA ; quality assessment; generalised linear model; empirical Bayes; weighted moderated statistic; invalid p-value; heteroscedasticity; WAME; heteroscedasticity;

    Abstract : DNA microarrays are strikingly efficient tools for analysing gene expression for large sets of genes simultaneously. The aim is often to identify genes which are differentially expressed between some studied conditions, thereby gaining insight into which cellular mechanisms are differently active between the conditions.

  5. 18. Preanalytical errors in hospitals : implications for quality improvement of blood sample collection

    Author : Olof Wallin; Christine Brulin; Kjell Grankvist; Johan Hultdin; Bethany van Guelpen; Ania Willman; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical errors; preanalytical; quality improvement; questionnaire; venous blood sampling; Clinical chemistry; Klinisk kemi;

    Abstract : Background: Most errors in the venous blood testing process are preanalytical, i.e. they occur before the sample reaches the laboratory. Unlike the laboratory analysis, the preanalytical phase involves several error-prone manual tasks not easily avoided with technological solutions. READ MORE

  6. 19. Sins of Omission and Commission : The Quality of Government and Civil Conflict

    Author : Hanne Fjelde; Erik Melander; Kristian Gleditsch; Uppsala universitet; []

    Abstract : Is the risk of civil conflict related to the quality of government? This dissertation contributes to the quantitative research on this topic. First, it provides a more nuanced account of the role of the government in influencing the risk of civil conflict. READ MORE

  7. 20. Network-Based Monitoring of Quality of Experience

    Author : Junaid Junaid; Markus Fiedler; Patrik Arlos; Astrid Undheim; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality of Experience; Network Performance; Network measurements;

    Abstract : The recent years have observed a tremendous shift from the technology-centric assessment to the user-centric assessment of network services. Consequently, measurement and modelling of Quality of Experience (QoE) attracted many contributions from researchers and practitioners. Generally, QoE is assessed via active and passive measurements.
