In this paper, a dataset, named 3DBodyTex, of static 3D body scans with high-quality texture information is presented along with a fully automatic method for body model fitting to a 3D scan. 3D shape modelling is a fundamental area of computer vision that has a wide range of applications in the industry. It is becoming even more important as 3D sensing technologies are entering consumer devices such as smartphones. As the main output of these sensors is the 3D shape, many methods rely on this information alone. The 3D shape information is, however, very high dimensional and leads to models that must handle many degrees of freedom from limited information. Coupling texture and 3D shape alleviates this burden, as the texture of 3D objects is complementary to their shape. Unfortunately, high-quality texture content is lacking from commonly available datasets, and in particular in datasets of 3D body scans. The proposed 3DBodyTex dataset aims to fill this gap with hundreds of high-quality 3D body scans with high-resolution texture. Moreover, a novel fully automatic pipeline to fit a body model to a 3D scan is proposed. It includes a robust 3D landmark estimator that takes advantage of the high-resolution texture of 3DBodyTex. The pipeline is applied to the scans, and the results are reported and discussed, showcasing the diversity of the features in the dataset. [less ▲]

We propose 3DBooSTeR, a novel method to recover a textured 3D body mesh from a textured partial 3D scan. With the advent of virtual and augmented reality, there is a demand for creating realistic and high-fidelity digital 3D human representations. However, 3D scanning systems can only capture the 3D human body shape up to some level of defects due to its complexity, including occlusion between bodyparts, varying levels of details, shape deformations and the articulated skeleton. Textured 3D mesh completion is thus important to enhance3D acquisitions. The proposed approach decouples the shape and texture completion into two sequential tasks. The shape is recovered by an encoder-decoder network deforming a template body mesh. The texture is subsequently obtained by projecting the partial texture onto the template mesh before inpainting the corresponding texture map with a novel approach. The approach is validated on the 3DBodyTex.v2 dataset [less ▲]

Situated at the axis of societal issues and academic research, the renewed popularity of applied history has raised several questions about its practice. The most direct questions come from non-academic partners. What can one expect of applied historians? How will those expectat ions be met? What if the methods and tools of applied history fall short of their goal? And is it even that important that organizations learn to think about the past , when they are oriented towards the present and future? Other questions stem from academic concerns. Is applied history more than a reiteration of public history? Do societal questions and concerns have a place within academic history departments? And if so, what are the ethical boundaries of this type of research? Some of these topics remain open questions. Some have been eloquently answered. Some remain subject of (fierce) discussion. Therefore, this third Corvus applied history workshop joins academic and non-academic expertise in order to assess and debate the value of applied history practices in different sectors. Discussants: Thomas Cauvin, Associate Professor of Public History, Luxembourg Centre for Contemporary and Digital History (C²DH) Gill Bennett OBE Senior Associate Fellow, Royal United Services Institute (RUSI) Foreign, Commonwealth & Development Office (FCDO) Historians Pieter Huistra Assistant Professor Theory of History, University of Utrecht Jason Steinhauer Global Fellow, The Wilson Center Koen Vandenweyer Delegation of Flanders to the European Union Alexandra Van den Berghe Corvus Research Project, KU Leuven Programme: 9.15am : Welcome 9.30am : New name, old practices? *(what is already out there)* 11am : Coffee break 11.30am : Where, when, how? *(what should be out there)* 1pm : Lunch break 2pm : What (not) to do? *(what should not be out there)* 3.30pm : Conclusions 3.45pm : End Starting questions: 9.30am : New name, old practices? *(what is already out there)* In these last few years t he notion of ‘Applied History’ has seen renewed popular ity. Proponents thereby often promise to reinvigorate the ‘long lost pr actice’ of using histor y in the present. Yet teachers, journalists, archivists, politicians, mar keteers and many others (including academics) have never stopped applying history in their professional activit ies. So do you think that there is already enough ‘applied history’ out there, particularly in your sector? 11.30am : Where, when, how? *(what should be out there)* The ‘next step’ in Applied History is usually considered to be the development of new ways of applying historical insight to issues in the present . This of course begs the question what those methods should be designed to do – what issues deserve attent ion and which new methods and tools look promising? In other words, what can or should applied history try to achieve as its ‘next step’? 2pm : What (not) to do? *(what should not be out there)* Not everybody believes that applying past insights to present concerns is a good idea. Some see no value in historical information, nor in historical thinking. Others fear the applicat ion of history in the present, as uses of the past become abuses of the past far too quickly. Therefor e, what do you think should be absolutely avoided when ‘doing ’ applied history? [less ▲]

The enzymatic mechanism of 3-phosphoglycerate to 3-phosphohydroxypyruvate oxidation, which forms the first step of the main conserved de novo serine synthesis pathway, has been revisited recently in certain microorganisms. While this step is classically considered to be catalyzed by an NAD-dependent dehydrogenase (e.g., PHGDH in mammals), evidence has shown that in Pseudomonas, Escherichia coli, and Saccharomyces cerevisiae, the PHGDH homologues act as transhydrogenases. As such, they use α-ketoglutarate, rather than NAD+, as the final electron acceptor, thereby producing D-2-hydroxyglutarate in addition to 3-phosphohydroxypyruvate during 3-phosphoglycerate oxidation. Here, we provide a detailed biochemical and sequence−structure relationship characterization of the yeast PHGDH homologues, encoded by the paralogous SER3 and SER33 genes, in comparison to the human and other PHGDH enzymes. Using in vitro assays with purified recombinant enzymes as well as in vivo growth phenotyping and metabolome analyses of yeast strains engineered to depend on either Ser3, Ser33, or human PHGDH for serine synthesis, we confirmed that both yeast enzymes act as transhydrogenases, while the human enzyme is a dehydrogenase. In addition, we show that the yeast paralogs differ from the human enzyme in their sensitivity to inhibition by serine as well as hydrated NADH derivatives. Importantly, our in vivo data support the idea that a 3PGA transhydrogenase instead of dehydrogenase activity confers a growth advantage under conditions where the NAD+:NADH ratio is low. The results will help to elucidate why different species evolved different reaction mechanisms to carry out a widely conserved metabolic step in central carbon metabolism. [less ▲]

Der Survey zu dem „Quality of Work Index Luxembourg“ (QoW), der von der Universität Luxemburg und der luxemburgischen Chambré des Salariés entwickelt wurde (Steffgen, Kohl, 2013; Sischka, Steffgen, 2015, 2016, 2017), wurde 2017 bereits zum fünften Mal mittels einer telefonischen Befragung durchgeführt. Ziel des Index ist es, die erlebte Arbeitssituation und -qualität luxemburgischer Arbeitnehmer zu erfassen. Der vorliegende Bericht dokumentiert die psychometrische Testung der Güte des aktuellen Erhebungsinstruments. Dazu erfolgt zunächst eine Beschreibung der für die Skalen genutzten Items, die Überprüfung der internen Konsistenz der jeweiligen Skala mittels verschiedener Reliabilitätsstatistiken (Cronbach’s Alpha, Korrelationsanalysen der Items) sowie Koeffizienten zur Beschreibung der Skalenverteilung. Konfirmatorische Faktorenanalysen dienen dazu, zu testen, ob die Items auf den a priori festgelegten Faktoren laden und ob sich die unterstellte Faktorenstruktur auch in den Daten zeigt. Außerdem werden die Zusammenhänge der Skalen mittels Korrelationsanalysen über-prüft. Die QoW-Skalen werden außerdem auf verschiedene Well-Being-Skalen regressiert, um deren Relevanz für den QoW-Index zu prüfen. Da der QoW Survey teilweise als Panelbefragung durchgeführt wird, wird außerdem geklärt, ob es hinsichtlich demographischer Eigenschaften der Befragten, hinsichtlich der QoW-Skalen oder hinsichtlich verschiedener Well-Being-Maße zu systematischen Ausfällen seit der letzten Welle gekommen ist. Ebenso werden einige Längsschnitt-Regressionsanalysen gerechnet, um zu überprüfen, ob einige Arbeitsbedingungen längerfristige Effekte auf das Well-Being der Arbeitnehmer aufweisen. Die QoW-Befragung 2017 hat außerdem das Schwerpunktthema „Digitalisierung“ behandelt. Die Themenblöcke werden mittels Latenter Profile-Analysen untersucht. Im Anschluss wird überprüft ob sich die extrahierten Profile hinsichtlich der QoW- und der Well-Being-Skalen unterscheiden. Abschließend wird das gesamte Erhebungsinstrument zusammenfassend diskutiert und Empfehlungen bezüglich der weiteren Entwicklung der Skalen gegeben. [less ▲]

Individuals continually interact with security mechanisms when performing tasks in everyday life. These tasks may serve personal goals or work goals, be individual or shared. These interactions can be influenced by peers and superiors in the respective environments (workplace, home, public spaces), by personality traits of the users, as well as by contextual constraints such as available time, cognitive resources, and perceived available effort. All these influencing factors, we believe, should be considered in the design, implementation and maintenance of good socio-technical security mechanisms. Therefore, we need to observe reliable socio-technical data, and then transform them into meaningful and helpful metrics for user interactions and influencing factors. More precisely, there are three main questions that the group discussed: 1. What data do we need to observe and what of this data we actually can observe and measure? 2. How can we observe and measure? 3. What can we do with the results of the observations? [less ▲]

The "4D Biology Workshop for Health and Disease", held on 16-17th of March 2010 in Brussels, aimed at finding the best organising principles for large-scale proteomics, interactomics and structural genomics/biology initiatives, and setting the vision for future high-throughput research and large-scale data gathering in biological and medical science. Major conclusions of the workshop include the following. (i) Development of new technologies and approaches to data analysis is crucial. Biophysical methods should be developed that span a broad range of time/spatial resolution and characterise structures and kinetics of interactions. Mathematics, physics, computational and engineering tools need to be used more in biology and new tools need to be developed. (ii) Database efforts need to focus on improved definitions of ontologies and standards so that system-scale data and associated metadata can be understood and shared efficiently. (iii) Research infrastructures should play a key role in fostering multidisciplinary research, maximising knowledge exchange between disciplines and facilitating access to diverse technologies. (iv) Understanding disease on a molecular level is crucial. System approaches may represent a new paradigm in the search for biomarkers and new targets in human disease. (v) Appropriate education and training should be provided to help efficient exchange of knowledge between theoreticians, experimental biologists and clinicians. These conclusions provide a strong basis for creating major possibilities in advancing research and clinical applications towards personalised medicine. [less ▲]
