HRCT Reference Atlas for Pulmonary Fibrosis Severity Score in Scleroderma Patients: Systemic Sclerosis (SSc) Visual Goh Scoring Atlas
Systemic sclerosis (SSc), also known as scleroderma, is a chronic, progressive connective tissue disease characterized by autoimmune phenomena, microangiopathy and fibrosis of the skin and internal organs. Pulmonary involvement by interstitial lung disease (SSc-ILD) is a significant cause of morbidity and mortality.
In order to facilitate assessing the severity of ILD according to the Goh scoring system, we have made this reference atlas based on High Resolution Computed Tomography (HRCT) images
Cardiovascular computed tomography : technical developments and clinical applications
Chapter 1 reviews technical developments of cardiac CT and current status, recommendations and future perspective of various clinical cardiac CT applications. In chapter 2, the eff ect of dose reduction on diagnostic performance in CT coronary angiography is assessed. Chapter 3 evaluates the eff ect of thin-slice image reconstructions on coronary artery calcium measurements. In chapter 4, the assessment of Agatston scores using coronary CT angiography is studied. Chapter 5 evaluates the predictive value of CT-derived RV/LV ratios and cardiac biomarkers for short term clinical outcome in patients with suspected acute PE. In chapter 6, the incremental value of ventricular function with ECG-synchronized cardiac CT over standard pulmonary CTA-derived RV/LV ratios for predicting clinical outcome in patients with suspected acute PE is discussed. Chapter 7 studies the influence of timing of NT-pro-BNP sampling for predicting adverse clinical outcome.Hartstichting Stichting IMAGOUBL - phd migration 201
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Technical advances in multi-slice computed tomography : dose assessment and clinical optimizations
The aim of this thesis was to develop, evaluate and implement technological advances in MDCT in clinical practice. Additionally dose assessment was performed to obtain more insight into the risk of radiation effects by using MDCT.Toshiba Medical SystemsUBL - phd migration 201
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
