- ItemSoft Inkjet Circuits: Rapid Multi-Material Fabrication of Soft Circuits using a Commodity Inkjet Printer(New York City : Association for Computing Machinery, 2019) Khan, Arshad; Roo, Joan Sol; Kraus, Tobias; Steimle, JürgenDespite the increasing popularity of soft interactive devices, their fabrication remains complex and time consuming. We contribute a process for rapid do-it-yourself fabrication of soft circuits using a conventional desktop inkjet printer. It supports inkjet printing of circuits that are stretchable, ultrathin, high resolution, and integrated with a wide variety of materials used for prototyping. We introduce multi-ink functional printing on a desktop printer for realizing multi-material devices, including conductive and isolating inks. We further present DIY techniques to enhance compatibility between inks and substrates and the circuits' elasticity. This enables circuits on a wide set of materials including temporary tattoo paper, textiles, and thermoplastic. Four application cases demonstrate versatile uses for realizing stretchable devices, e-textiles, body-based and re-shapeable interfaces.

- ItemVariations of the aerosol chemical composition during Asian dust storm at Dushanbe, Tajikistan(Les Ulis : EDP Sciences, 2019) Fomba, Khanneh Wadinga; Müller, Konrad; Hofer, Julian; Makhmudov, Abduvosit N.; Althausen, Dietrich; Nazarov, Bahron I.; Abdullaev, Sabur F.; Herrmann, HartmutAerosol chemical composition was characterized during the Central Asian Dust Experiment (CADEX) at Dushanbe (Tajikistan). Aerosol samples were collected during a period of 2 months from March to May 2015 using a high volume DIGITEL DHA-80 sampler on quartz fiber filters. The filters were analyzed for their ionic, trace metals as well as organic and elemental carbon (OC/EC) content. The aerosol mass showed strong variation with mass concentration ranging from 18 μg/m3 to 110 μg/m3. The mineral dust concentrations varied between 0.9 μg/m3 and 88 μg/m3. Days of high aerosol mass loadings were dominated by mineral dust, which made up to about 80% of the aerosol mass while organic matter and inorganic ions made up about 70% of the aerosol mass during days of low aerosol mass loadings. The mineral dust composition showed different trace metal signatures in comparison to Saharan dust with higher Ca content and Ca/Fe ratios twice as high as that observed in Saharan dust. Strong influence of anthropogenic activities was observed in the trace metal concentrations with Zn and Pb concentrations ranging from 7 to 197 ng/m3 and 2 to 20 ng/m3, respectively. Mineral dust and anthropogenic activities relating to traffic, combustion as well as metallurgical industrial emissions are identified as the sources of the aerosol during this period. © 2019 The Authors, published by EDP Sciences.
- ItemTwo-Phase Fluid Flow Experiments Monitored by NMR(Les Ulis : EDP Sciences, 2020) Hiller, Thomas; Hoder, Gabriel; Amann-Hildenbrand, Alexandra; Klitzsch, Norbert; Schleifer, NorbertWe present a newly developed high-pressure nuclear magnetic resonance (NMR) flow cell, which allows for the simultaneous determination of water saturation, effective gas permeability and NMR relaxation time distribution in two-phase fluid flow experiments. We introduce both the experimental setup and the experimental procedure on a tight Rotliegend sandstone sample. The initially fully water saturated sample is systematically drained by a stepwise increase of gas (Nitrogen) inlet pressure and the drainage process is continuously monitored by low field NMR relaxation measurements. After correction of the data for temperature fluctuations, the monitored changes in water saturation proved very accurate. The experimental procedure provides quantitative information about the total water saturation as well as about its distribution within the pore space at defined differential pressure conditions. Furthermore, the relationship between water saturation and relative (or effective) apparent permeability is directly determined. © The Authors, published by EDP Sciences, 2020.
- ItemMoving towards FAIRness in Research Data and Software Management(Meyrin : CERN, 2020-07-03) Kraft, AngelinaPresentation during the Thüringer FDM Tage 2020 within the workshop "FAIR Research Software and Beyond: How to make the most of your code".
- ItemPlan S in der institutionellen Strategie(Meyrin : CERN, 2020-09-15) Tullney, MarcoPlan S ist eine Initiative von Forschungsförderorganisationen zur einheitlichen und nachdrücklichen Umsetzung von Open-Access-Anforderungen. Die von den Förderern gestellten Anforderungen binden zunächst nur die von ihnen geförderten Wissenschaftler\*innen. Dennoch lassen sich die Anforderungen aus dem Plan S für die institutionelle Ausrichtung sinnvoll nutzen. Plan S beinhaltet bereits den Anspruch, Open-Access-Anforderungen zu harmonisieren und auch auf institutionelle Regelungen zu wirken. Durch die Anforderungen für Zeitschriften wird ein deutlicher Veränderungsdruck auf Verlage ausgeübt. Dieser Entwicklung könnten sich Bibliotheken anschließen und ebenfalls auf eine nachhaltige und unumkehrbare Open-Access-Transformation drängen. Lokale Gestaltungsspielräume gibt es genug. Förderkonditionen von Publikationsfonds und anderen Instrumenten, eigene Erwerbungs- und Finanzierungsentscheidungen, eigene Policies und Verpflichtungen von Autor\*innen der eigenen Institution. Auch Open-Access-Anforderungen von Organisationen, die entweder keine Forschungsförderer sind oder sich aus bestimmten Gründen nicht komplett dem Plan S verpflichten möchten, könnten den Plan-S-Kriterien angeglichen werden. Wie ist Plan S aus institutioneller Sicht zu bewerten? Wie wirkt Plan S über den unmittelbaren Geltungsbereich hinaus? Welche Handlungsmöglichkeiten vor Ort sind davon betroffen? Wie kann man über die Anforderungen hinausgehen, ohne den gemeinsamen Weg zu verlassen? Welche Schwierigkeiten werden gesehen? Welche Rolle kann Plan S in der institutionellen Open-Access-Strategie spielen? Im Vortrag wird auch auf die Änderungen eingegangen, die Plan S im Laufe des letzten Jahres erfahren hat.
- ItemVertical profiles of dust and other aerosol types above a coastal site(Les Ulis : EDP Sciences, 2019) Althausen, Dietrich; Mewes, Silke; Heese, Birgit; Hofer, Julian; Schechner, Yoav; Aides, Amit; Holodovsky, VadimMonthly mean vertical profiles of aerosol type occurrences are determined from multiwavelength Raman and polarization lidar measurements above Haifa, Israel, in 2017. This contribution presents the applied methods and threshold values. The results are discussed for one example, May 2017. This month shows more often large, non-spherical particles in lofted layers than within the planetary boundary layer. Small particles are observed at higher altitudes only when they are observed in lower altitudes, too. © 2019 The Authors, published by EDP Sciences.
- ItemSoil conditions and the iron chlorosis of mature vine(London [u.a.] : Institute of Physics, 2019) Yutsis, A.E.; Zhelezova, S.V.; Dammer, K.-H.Iron-deficiency chlorosis is a usual routine problem on calcareous carbonated soils of Crimea. Different reasons cause vine chlorosis: soil properties, physiological status of plants and others. It was shown that chlorosis spot in the vineyard has constant location. Chlorosis can be identified visually and instrumentally. In this study, an attempt was made to find the relationship between soil electrical resistance and the spread of vine chlorosis.
- ItemThe ATMODAT Standard enhances FAIRness of Atmospheric Model data(Washington, DC : ESSOAr, 2020) Heydebreck, Daniel; Kaiser, Amandine; Ganske, Anette; Kraft, Angelina; Schluenzen, Heinke; Voss, VivienWithin the AtMoDat project (Atmospheric Model Data, www.atmodat.de), a standard has been developed which is meant for improving the FAIRness of atmospheric model data published in repositories. Atmospheric model data form the basis to understand and predict natural events, including atmospheric circulation, local air quality patterns, and the planetary energy budget. Such data should be made available for evaluation and reuse by scientists, the public sector, and relevant stakeholders. Atmospheric modeling is ahead of other fields in many regards towards FAIR (Findable, Accessible, Interoperable, Reusable, see e.g. Wilkinson et al. (2016, doi:10.1101/418376)) data: many models write their output directly into netCDF or file formats that can be converted into netCDF. NetCDF is a non-proprietary, binary, and self-describing format, ensuring interoperability and facilitating reusability. Nevertheless, consistent human- and machine-readable standards for discipline-specific metadata are also necessary. While standardisation of file structure and metadata (e.g. the Climate and Forecast Conventions) is well established for some subdomains of the earth system modeling community (e.g. the Coupled Model Intercomparison Project, Juckes et al. (2020, https:doi.org/10.5194/gmd-13-201-2020)), other subdomains are still lacking such standardisation. For example, standardisation is not well advanced for obstacle-resolving atmospheric models (e.g. for urban-scale modeling). The ATMODAT standard, which will be presented here, includes concrete recommendations related to the maturity, publication, and enhanced FAIRness of atmospheric model data. The suggestions include requirements for rich metadata with controlled vocabularies, structured landing pages, file formats (netCDF), and the structure within files. Human- and machine-readable landing pages are a core element of this standard and should hold and present discipline-specific metadata on simulation and variable level.
- ItemOCK – Open Climate Knowledge(Meyrin : CERN, 2020-01-14) Murray-Rust, Peter; Worthington, Simon100% open collaborative research for climate change knowledge / using data mining & open science publishing. The climate crisis of the predicted atmosphere temperatures rising to 1.5C + makes it imperative that research related to climate change be put to better use by being open and digitally connected. We are concerned with making all aspects of research open, but as an example, less than 30% of research papers related to climate change are Open Access (Tai and Robinson 2018). This must change now!
