Robotics is gaining an importance among the subjects to be studied in scientific and engineering disciplines. However, being a quite new discipline with a high degree of inter- and trans-disciplinary aspects, the teaching community cannot rely on experience, gained by a long history of experiments. With this paper we propose means to help assess and improve study programs in robotics. The approach is based on the idea of concept inventories (CIs) and related tests to derive objective information for a comparison of student groups with each other and over time, e.g. to assess learning gain for specific measures. The approach helps to further establish quality assurance in the design of robotics study programs and equips teachers with measures for a formative assessment of their work. © Springer International Publishing Switzerland 2017.

In their article, Lang, Weiss, Gerstorf, & Wagner, (2013) use the adult life span sample of the national German Socio-Economic Panel (GSOEP) to explore functional outcomes of life satisfaction with regard to hazards of mortality. Their findings suggest that "being overly optimistic [in] predicting a better future than actually observed was associated with [. . .] a great risk of mortality within the following decade." In this short paper, we analyze the same data set using the same model, but, in addition to the self-rated health status in the starting year included in the model by Lang et al. (2013), we furthermore control for the self-rated health at the target year. With this modification, it turns out that the accuracy of anticipated future life satisfaction has no significant effect on mortality. Two additional analyses underpin this finding. © 2016 Hogrefe Publishing.

Baltic Gender is a consortium of research organisations and higher education institutions from the Baltic Sea Region aiming at reducing gender segregation and gender inequalities in Marine Science and Technology. The diversity of the consortium members (from Nordic, Continental and Eastern countries) with regard to gender equality policies and practices as well as gatekeeping provides an excellent basis for exchange, comparison, collaborative learning and transfer of knowledge. The action will work toward the establishment and implementation of Gender Equality Plans (GEPs) as instruments that can catalyse institutional change. Collection, standardisation and evaluation of gender-segregated data will facilitate the establishment of gender-sensitive indicators and enable the consortium to develop concrete targets and measures for reaching the set goals of the GEPs and to monitor the progress of their implementation. GEP implementation activities will be supported by established approaches and innovative strategies developed in the four core work packages on (i) career advancement, (ii) work and family, (iii) structural changes, and (iv) gender dimension in marine research. Cross-cutting work packages will support actions progress via giving trainings, strengthening networks, raising awareness, disseminating results and reaching out to a wider scientific community and public in general. The outputs are designed to maximize impact and, due to the inter-disciplinary nature of marine sciences, to have a broader impact in the field of natural science and technology. The deliverables include blogs, brochures, best-practice handbooks, recommendations, training-materials, synthesis reports. Schemes and good practices established during the action (e.g., grass-root networks, work-family balance, transparency in decision making, modernised recruitment processes, mentoring) are foreseen to pave the way for long-lasting institutional practices.

Background-Blood oxygen level-dependent (BOLD) cardiac magnetic resonance imaging (CMR) has been shown to be able to detect myocardial perfusion differences. However, validation of BOLD CMR against fractional flow reserve (FFR) is lacking. The aim of our study was to analyze the potential diagnostic accuracy of BOLD CMR in comparison to invasively measured FFR, which served as gold standard for a hemodynamic significant coronary lesion. Methods and Results-BOLD image was performed at rest and during adenosine infusion in a 1.5-T CMR scanner. Thirty-six patients were analyzed for relative BOLD signal intensity increase according to the 16-segment model. Invasive FFR measurements were performed in the 3 major coronary arteries during adenosine infusion in all patients. An FFR?0.8 was regarded to indicate a significant coronary lesion. Relative BOLD signal intensity increase was significantly lower in myocardial segments supplied by coronary arteries with an FFR?0.8 compared with segments with an FFR>0.8 (1.1±0.2 versus 1.5±0.2; P <0.0001). Sensitivity and specificity yielded 88.2% and 89.5%, respectively. Conclusions-CMR BOLD imaging reliably detects hemodynamic significant coronary artery disease and is, thus, an alternative to contrast-enhanced perfusion studies. © 2012 American Heart Association, Inc.

We use supported alumina templates and electrodeposition to fabricate self-standing Au-nanorods (Au-NR) arrays. Depending on electrolyte and deposition conditions two different NR morphologies with either corrugated or smooth topologies are fabricated. We show that the properties of the NR arrays, including amphiphilic and optical, very much depend on their morphology. Smooth NR arrays are hydrophobic while the corrugated ones are hydrophilic. Also the optical reflectance, though it shows plasmon resonances at very similar wave lengths, is much lower for the corrugated NR arrays. The activity of the NR arrays as substrates for molecular detection using Raman scattering, and Rhodamine 6G (R6G) as model dye, also strongly depends on their morphology. R6G concentrations down to 1 pM are detected on the corrugated arrays yielding an effective enhancement factor (EF) of approximately 1 × 109. In contrast an over-estimated (because of their hydrophobic character) EF of 6 × 106 is obtained for the smooth NR arrays. © 2010 Elsevier Ltd.

In this letter, the electrocaloric effect (ECE) of 111- and 001-oriented 0.71PbMg 1/3Nb 2/3O 3-0.29PbTiO 3 (0.71PMN-0.29PT) single crystals is investigated with emphasis on the effects of phase transitions and their dependence on electric field. We show that crystal orientation and more specifically the complex phase transitions taking place in the specific composition above have large effects on the maximum ECE temperature, ΔT max, its peak temperature, T EC, and the width of the ECE peak of the δT(T) curve. The investigation shows that ECE may be tuned by a proper choice of 0.71PMN-0.29PT crystal orientations. © 2012 American Institute of Physics.

We process silver nanostructures via electrodeposition into porous aluminium oxide templates. The degree of pore ordering determines the morphology of the silver nanostructure from smooth to branched nanowires. Nanostructures reminiscent of fir-twigs form in templates with large and low-ordered pores. We demonstrate the usefulness of these nano-fir-twigs as SERS substrates using a 10-15 M R6G dye solution. The enhancement factor of 1011 obtained should allow single molecules to be detected. © 2010 The Royal Society of Chemistry.

The 360° medium, an immersive dome-based video projection environment (immer-sive dome environment (IDE)) also called 'fulldome', is often seen as an old concept of a traditional planetarium setting. This article invites the reader to look at it as a unique, hybrid media format, which opens new ways of perception. © 2012 Intellect Ltd Miscellaneous. English language.

Large-area ordered nanorod (NR) arrays of various functional materials can be easily and cost-effectively processed using on-substrate anodized porous aluminum oxide (PAO) films as templates. However, reproducibility in the processing of PAO films is still an issue because they are prone to delamination, and control of fabrication parameters such as electrolyte type and concentration and anodizing time is critical for making robust templates and subsequently mechanically reliable NR arrays. In the present work, we systematically investigate the effects of the fabrication parameters on pore base morphology, devise a method to avoid delamination, and control void formation under the barrier layer of PAO films on gold underlayers. Via systematic control of the anodization parameters, particularly the anodization current density and time, we follow the different stages of void development and discuss their formation mechanisms. The practical aspect of this work demonstrates how void size can be controlled and how void formation can be utilized to control the shape of NR bases for improving the mechanical stability of the NRs. © 2016 American Chemical Society.

We process one-dimensional (1D) NiO nanostructures in anodized alumina templates starting from electrochemically deposited Ni nanotubes (NTs), and characterize their morphology-dependent supercapacitance behavior. The morphology of the 1D NiO nanostructures is controlled by the time of annealing at 450°C. After 25 min of annealing, the NTs start to close but maintain the tubular structure, and after a further 300 min of annealing time, the tubes are completely closed and nanorods (NRs) are formed. We show that the structures obtained are highly promising for supercapacitor applications; the performance of the NiO NT structure is with a specific capacitance of 2,093 F/g, the highest ever obtained for NiO, approaching the theoretical capacitance of this material. A suitable combination of nanocrystalline grain size and the high surface area akin to the tubular structure is responsible for this high performance. In contrast, the NiO NR structure is characterized by lower performance (797 F/g). A further attribute of the proposed structure is its high stability against galvanostatic chargingdischarging cycling at high current densities, with almost no alteration to performance after 500 cycles. © 2013 Dar et al.; licensee Springer.
