description: Background/Aims: Gestational diabetes (GDM) might be associated with alterations in the metabolomic profile of affected mothers and their offspring. Until now, there is a paucity of studies that investigated both, the maternal and the fetal serum metabolome in the setting of GDM. Mounting evidence suggests that the fetus is not just passively affected by gestational disease but might play an active role in it. Metabolomic studies performed in maternal blood and fetal cord blood could help to better discern distinct fetal from maternal disease interactions. Methods: At the time of birth, serum samples from mothers and newborns (cord blood samples) were collected and screened for 163 metabolites utilizing tandem mass spectrometry. The cohort consisted of 412 mother/child pairs, including 31 cases of maternal GDM. Results: An initial non-adjusted analysis showed that eight metabolites in the maternal blood and 54 metabolites in the cord blood were associated with GDM. After Benjamini-Hochberg (BH) procedure and adjustment for confounding factors for GDM, fetal phosphatidylcholine acyl-alkyl C 32:1 and proline still showed an independent association with GDM. Conclusions: This study found metabolites in cord blood which were associated with GDM, even after adjustment for established risk factors of GDM. To the best of our knowledge, this is the first study demonstrating an independent association between fetal serum metabolites and maternal GDM. Our findings might suggest a potential effect of the fetal metabolome on maternal GDM. (c) 2018 The Author(s) Published by S. Karger AG, Basel

description: We present a new analysis of the Aquarius simulations done in combination with a semi-analytic galaxy formation model. Our goal is to establish whether the subhalos present in LCDM simulations of Milky Way-like systems could host the dwarf spheroidal (dSph) satellites of our Galaxy. Our analysis shows that, contrary to what has been assumed in most previous work, the mass profiles of subhalos are generally not well fit by NFW models but that Einasto profiles are preferred. We find that for shape parameters alpha = 0.2 - 0.5 and Vmax = 10 - 30 km/s there is very good correspondence with the observational constraints obtained for the nine brightest dSph of the Milky Way. However, to explain the internal dynamics of these systems as well as the number of objects of a given circular velocity the total mass of the Milky Way should be ~ 8x10^11 Msun, a value that is in agreement with many recent determinations, and at the low mass end of the range explored by the Aquarius simulations. Our simulations show important scatter in the number of bright satellites, even when the Aquarius Milky Way-like hosts are scaled to a common mass, and we find no evidence for a missing population of massive subhalos in the Galaxy. This conclusion is also supported when we examine the dynamics of the satellites of M31.

description: Material surfaces with tailored aerophobicity are crucial for applications where gas bubble wettability has to be controlled, e.g., gas storage and transport, electrodes, bioreactors or medical devices.

Here, we present switchable underwater aerophobicity of hydrophobic polymeric substrates, which respond to heat with multilevel micro- and nanotopographical changes. The cross-linked poly[ethylene-co-(vinyl acetate)] substrates possess arrays of microcylinders with a nanorough top surface. It is hypothesized that the specific micro-/nanotopography of the surface allows trapping of a water film at the micro interspace and in this way generates the aerophobic behavior. The structured substrates were programmed to a temporarily stable, nanoscale flat substrate showing aerophilic behavior. Upon heating, the topographical changes caused a switch in contact angle from aerophilic to aerophobic for approaching air bubbles. In this way, the initial adhesion of air bubbles to the programmed flat substrate could be turned into repellence for the recovered substrate surface. The temperature at which the repellence of air bubbles starts can be adjusted from 58 ± 3 °C to 73 ± 3 °C by varying the deformation temperature applied during the temperature-memory programming procedure. The presented actively switching polymeric substrates are attractive candidates for applications, where an on-demand gas bubble repellence is advantageous.

We present a detailed discussion on the boundary conditions the wave function has to satisfy when crossing the support of the potential, proceeding then to explore the dependence of the ground state on the parameter a, analyzing the occurrence of supercritical effects. We also apply the Foldy-Wouthuysen transformation, discussing the non-relativistic limit of this problem.

description: The advanced world-wide network of gravitational waves (GW) observatories is scheduled to begin operations within the current decade. Thanks to their improved sensitivity, they promise to yield a number of detections and thus to open a new observational windows for astronomy and astrophysics. Among the scientific goals that should be achieved, there is the independent measurement of the value of the cosmological parameters, hence an independent test of the current cosmological paradigm. Due to the importance of such task, a number of studies have evaluated the capabilities of GW telescopes in this respect. However, since GW do not yield information about the source redshift, different groups have made different assumptions regarding the means through which the GW redshift can be obtained. These different assumptions imply also different methodologies to solve this inference problem. This work presents a formalism based on Bayesian inference developed to facilitate the inclusion of all assumptions and prior information about a GW source within a single data analysis framework. This approach guarantees the minimisation of information loss and the possibility of including naturally event-specific knowledge (such as the sky position for a Gamma Ray Burst - GW coincident observation) in the analysis. The workings of the method are applied to a specific example, loosely designed along the lines of the method proposed by Schutz in 1986, in which one uses information from wide-field galaxy surveys as prior information for the location of a GW source. I show that combining the results from few tens of observations from a network of advanced interferometers will constrain the Hubble constant $H_0$ to an accuracy of $\sim 4 - 5$% at 95% confidence.

Subjects: ING-INF/01 Elettronica

description: New configuration of the notch and bandstop filters is proposed and investigated. Here a rejection section is based on a thin slotted H-plane strip that may be considered as a limiting case of a three-slot iris. Such a section forms symmetrical frequency response with very low insertion loss out of the stopband. The results of numerical design and measurement data are given for a 3% notch filter and for 2% three-section bandstop one. In the low-power applications the proposed notch filter is probably the simplest one due to its easy fabrication and a possibility to be incorporated into a waveguide circuit by placing between the waveguide flanges.
Interactive Art, Performance and Scientific Research into Corporeal Empathy

description: This paper presents the evaluation of a design research project that combines artistic practice and academic theory at a high standard in both fields, proving that the problem-based learning (PBL) is a strong method for bridging the gap between those fields. “Researching Empathy Through Performance” was a Master thesis of Interaction Design and consisted of the development of an artistic performance entitled “My Body, Your Room”, which functioned as a site for conducting scientific research into corporeal empathy. The project investigated how embodied methodologies that combine dance performance and interactive technologies can strengthen empathic relationships between the audience, performer, and the environment. The project was developed at the Kolding School of Design in Denmark, and utilised cross-disciplinary theories, concepts and methods from interaction design, performance studies and neurology. The working methodology drew on artistic approaches and scientific research methods such as quantitative and qualitative analysis; the analysis included video documentation, ethnography, surveys and interviews.

description: As modern circuits become smaller and the frequencies that they work at become higher, inevitably, parasitic coupling within the circuits starts to influence the behavior of the circuit more and more. Therefore it is necessary to include the influence of mutual coupling in the circuit simulators that are used to design the circuit. In this paper the circuit is divided into three classes of building blocks: transmission lines, small discontinuities (components) and meshed structures (solved using classical MoM). We will describe software modules that can calculate the couplings between these classes. The three modules are compatible with each other because they use the same parameters (incoming and outgoing waves at the ports, incident fields and radiating currents). They can be easily combined with a normal circuit simulation engine to include mutual coupling.

description: Climate change, along with socio-economic development, will increase the economic impacts of floods. While the factors that influence flood risk to private property have been extensively studied, the risk that natural disasters pose to public infrastructure and the resulting implications on public sector budgets, have received less attention. We address this gap by developing a two-staged model framework, which first assesses the flood risk to public infrastructure in Austria. Combining exposure and vulnerability information at the building level with inundation maps, we project an increase in riverine flood damage, which progressively burdens public budgets. Second, the risk estimates are integrated into an insurance model, which analyzes three different compensation arrangements in terms of the monetary burden they place on future governments' budgets and the respective volatility of payments. Formalized insurance compensation arrangements offer incentives for risk reduction measures, which lower the burden on public budgets by reducing the vulnerability of buildings that are exposed to flooding. They also significantly reduce the volatility of payments and thereby improve the predictability of flood damage expenditures. These features indicate that more formalized insurance arrangements are an improvement over the purely public compensation arrangement currently in place in Austria.

description: We study domain-walls and bubble nucleation in a non-relativistic vector field theory with different longitudinal and transverse speeds of sound. We describe analytical and numerical methods to calculate the orientation dependent domain-wall tension, $σ(θ)$. We then use this tension to calculate the critical bubble shape. The longitudinally oriented domain-wall tends to be the heaviest, and sometime suffers an instability. It can spontaneously break into zigzag segments. In this case, the critical bubble develops kinks, and its energy, and therefore the tunneling rate, scales with the sound speeds very differently than what would be expected for a smooth bubble.

Year: 2018

description: This paper proposes, exemplifies and discusses a new design method, including both artistic and scientific modes of working. It is based on the idea of integrated design processes driven by strategic implementation of what is termed sequential primary generators. The paper initiates by discussing design and creative process research and filters central aspects that are coalesced with a proposed tree-phase early stage design method. The proposed architectural design method has been applied in three university projects. In the last project, students where asked to respond to a questionnaire survey to identify the growth of design and creative capabilities from a student perspective. The paper presents the results and discussion based upon these projects and studies. Survey answers show that the proposed design method increases both design quality and design knowledge. This suggest that other creative processes may be addressed through this design methodology, featuring both problem and solution driven procedures.

Bisociation of artistic and academic approaches in problem-based projects
Creators: name: Heinrich, Falk
Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2018

description: This article presents a theoretical elaboration of the potential relationship between the academic and artistic approaches within a problem-based educational setting. The investigation is based on Koestler’s idea of the “bisociation” (blending) of dissimilar thinking and action matrices as the foundational mechanism of human creation in academic discovering, artistic creation, and humour, respectively. On the basis of my own experiences with higher education pedagogy exemplified by a concrete workshop held with students from two different educational programmes at Aalborg University, the article investigates the bisociation of artistic and academic matrices and codes by scrutinising how these apparent incompatibilities could be functions of a blending mechanism. The article proposes that the bisociation of the artistic and academic approaches should be understood as mutual inscriptions leading to an emphasised correlation between academic abstractions and associative-emotional experiences leading to an increase in complexity, specifically, a multifaceted understanding and emotional perception of today’s societal challenges.

Co-Lab on Developing Cyborg Arts – Interdisciplinary Collaboration and Practice Based Solutions
Creators: name: Pearlman, Ellen
Publisher: name: Journal of Problem Based Learning in Higher Education
Year: 2018

description: The world’s first co-lab in Cyborg Arts was conducted at Parsons/New School University over the course of sixteen weeks. This paper investigates the use of Donald Schon’s Reflect Practice Methodology (Schon 1983) and Bruno Latour’s Actor Network Theory (Latour 2005) in facilitating new solutions. Previously, an open call had been placed in targeted venues such as Art and Education, as well as a number of technology user groups in the New York City area to solicit ideas and participants. With the help of the Cyborg Foundation, three teams were chosen to build prototypes of a new cyborg sense: Team Glass, Team Radiation and Team Haptics. Team Glass strove to make a cyborg sense detecting the rhythm of changes in the sun’s solar flares; Team Radiation decided to make a sense to distinguish and alert the user to different types of organic and inorganic radiation in the environment, and Team Haptics wanted to use one of the participant’s own body to correct a medical problem with their nervous system’s coordination of gait. Students from Parsons MFADT program self-selected a team to work with. Specialists and guests either visited the co-lab or used Skype to converse with the participants during the course of the semester. Communication channels on Slack and Tumblr allowed immediate cross sharing of information, as well as searchable archives of group practice. Registered Parsons students stayed committed to the lab in order to receive a grade. Other participants had various reasons to be involved, such as learning new skills, seeing their ideas realized, and stepping outside of their core discipline. The major conduits of communication for the teams outside of lab time were the web-based Slack application that logged a history of their thoughts and interactions, and an additional private Tumblr for the students to share their ideas in documenting their progress. This paper examines how critical interventions at key moments in group dynamics with these methodologies and analyses led to breakthroughs and dynamic interpretations of these sensing techniques, and thus new aspects of cyborg art.

Undergraduate student nurses experiences of vertical violence
Creators: name: Abulaban, Hiam
Publisher: name: University of British Columbia
Year: 2013

description: Vertical violence is the term used to describe abusive and bullying behaviours among a group of people with unequal power. Vertical violence is used in this study because the recipients of abusive behaviours are students. The goal of this phenomenological study was to elicit a description of the lived experience of nursing students with vertical violence during their clinical placements in three major hospitals in Palestine. Findings suggest that nursing students are experiencing and witnessing bullying behaviours in different forms, most notably by staff nurses and head nurses. Students reported that their experiences with vertical violence lessen as they advance in their clinical education and gain more skills. The majority of the students told someone about their experiences. Experiencing vertical violence was found to impact the students' learning, socialization and clinical practice. The students reported using different coping strategies to deal with vertical violence. Implications for practice include ensuring that if the issue of vertical violence is not dealt with, it will have a detrimental effect on the student nurses and on their practice. Recommendations include providing policies to address this issue and provide reporting guidelines for student nurses. Also teaching nursing students and nurses about vertical violence is to be a top priority for the schools of nursing and hospital managements.

description: The thermal structure of subduction zones exerts a major influence on deep-seated mechanical and chemical processes controlling arc magmatism, seismicity, and global element cycles. Accretionary complexes exposed inland may comprise tectonic blocks with contrasting pressure-temperature (P-T) histories, making it possible to investigate the dynamics and thermal evolution of former subduction interfaces. With this aim, we present new Lu-Hf geochronological results for mafic rocks of the Halilbagi Complex (Anatolia) that evolved along different thermal gradients. Samples include a lawsonite-epidote blueschist, a lawsonite-epidote eclogite, and an epidote eclogite (all with counter-clockwise P-T paths), a prograde lawsonite blueschist with a "hairpin"-type P-T path, and a garnet amphibolite from the overlying sub-ophiolitic metamorphic sole. Equilibrium phase diagrams suggest that the garnet amphibolite formed at similar to 0.6-0.7 GPa and 800-850 degrees C, whereas the prograde lawsonite blueschist records burial from 2.1 GPa and 420 degrees C to 2.6 GPa and 520 degrees C. Well-defined Lu-Hf isochrons were obtained for the epidote eclogite (92.38 +/- 0.22 Ma) and the lawsonite-epidote blueschist (90.19 +/- 0.54 Ma), suggesting rapid garnet growth. The lawsonite-epidote eclogite (87.30 +/- 0.39 Ma) and the prograde lawsonite blueschist (ca. 86 Ma) are younger, whereas the garnet amphibolite (104.5 +/- 3.5 Ma) is older. Our data reveal a consistent trend of progressively decreasing geothermal gradient from granulite-facies conditions at similar to 104 Ma to the epidote-eclogite facies around 92 Ma, and the lawsonite blueschist-facies between 90 Ma and 86 Ma. Three Lu-Hf garnet dates (between 92 Ma and 87 Ma) weighted toward the growth of post-peak rims (as indicated by Lu distribution in garnet) suggest that the HP/LT rocks were exhumed continuously and not episodically. We infer that HP/LT metamorphic rocks within the Halilbagi Complex were subjected to continuous return flow, with "warm" rocks being exhumed during the tectonic burial of "cold" ones. Our results, combined with regional geological constraints, allow us to speculate that subduction started at a transform fault near a mid-oceanic spreading centre. Following its formation, this ancient subduction interface evolved thermally over more than 15 Myr, most likely as a result of heat dissipation rather than crustal underplating.

description: The current knowledge on the stellar IMF is documented. It appears to become top-heavy when the star-formation rate density surpasses about 0.1Msun/(yr pc^3) on a pc scale and it may become increasingly bottom-heavy with increasing metallicity and in increasingly massive early-type galaxies. It declines quite steeply below about 0.07Msun with brown dwarfs (BDs) and very low mass stars having their own IMF. The most massive star of mass mmax formed in an embedded cluster with stellar mass Mecl correlates strongly with Mecl being a result of gravitation-driven but resource-limited growth and fragmentation induced starvation. There is no convincing evidence whatsoever that massive stars do form in isolation. Various methods of discretising a stellar population are introduced: optimal sampling leads to a mass distribution that perfectly represents the exact form of the desired IMF and the mmax-to-Mecl relation, while random sampling results in statistical variations of the shape of the IMF. The observed mmax-to-Mecl correlation and the small spread of IMF power-law indices together suggest that optimally sampling the IMF may be the more realistic description of star formation than random sampling from a universal IMF with a constant upper mass limit. Composite populations on galaxy scales, which are formed from many pc scale star formation events, need to be described by the integrated galactic IMF. This IGIMF varies systematically from top-light to top-heavy in dependence of galaxy type and star formation rate, with dramatic implications for theories of galaxy formation and evolution.

description: A simulation program is developed based on Grover’s formulas and Greenhouse method to calculate the inductance value and Q-factor for particular dimension and width distribution of spiral inductors. This program changes the width distribution through a pre-determined number of quadratic distributions in an attempt to reduce energy losses and improve Q-factor. The result of this program provides a higher Q-factor together with the possibility of reducing the overall dimension of square spiral inductors as compared with conventional designs. The coordinates of dimension for the simulated inductor are also calculated enabling ease of verification and fabrication. Finally, the calculated results are verified by simulating the inductor using HPADS momentum which is MOM based electromagnetic simulator. The ease of use and rapid results of this program can find its attractiveness in wireless communications and related areas.

description: Following the mandate in the Paris Agreement for signatories to provide “climate services” to their constituents, “downscaled” climate visualizations are proliferating. But the process of downscaling climate visualizations does not neutralize the political problems with their synoptic global sources—namely, their failure to empower communities to take action and their replication of neoliberal paradigms of globalization. In this study we examine these problems as they apply to interactive climate‐visualization platforms, which allow their users to localize global climate information to support local political action. By scrutinizing the political implications of the “zoom” tool from the perspective of media studies and rhetoric, we add to perspectives of cultural cartography on the issue of scaling from our fields. Namely, we break down the cinematic trope of “zooming” to reveal how it imports the political problems of synopticism to the level of individual communities. As a potential antidote to the politics of zoom, we recommend a downscaling strategy of connectivity, which associates rather than reduces situated views of climate to global ones.

description: A comparison between flip-chip mounting of monolithic microwave integrated circuits (MMICs) in microstrip transmission line technology and coplanar transmission line technology is presented. The influence of substrate proximity effects on the electrical behavior of the MMICs is examined and illustrated innormalized frequency independent graphs. Based on the esults of this work, the performance of microstrip-MMICs used in flip-chip configuration can be estimated as a function of the chosen assembly geometry.

description: We investigate the backflow effect in elementary quantum mechanics - the phenomenon in which a state consisting entirely of positive momenta may have negative current and the probability flows in the opposite direction to the momentum. We compute the current and flux for states consisting of superpositions of gaussian wave packets. These are experimentally realizable but the amount of backflow is small. Inspired by the numerical results of Penz et al (M.Penz, G.Grübl, S.Kreidl and P.Wagner, J.Phys. A39, 423 (2006)), we find two non-trivial wave functions whose current at any time may be computed analytically and which have periods of significant backflow, in one case with a backwards flux equal to about 70 percent of the maximum possible backflow, a dimensionless number $c_{bm} \approx 0.04 $, discovered by Bracken and Melloy (A.J.Bracken and G.F.Melloy, J.Phys. A27, 2197 (1994)). This number has the unusual property of being independent of $\hbar$ (and also of all other parameters of the model), despite corresponding to an obviously quantum-mechanical effect, and we shed some light on this surprising property by considering the classical limit of backflow. We discuss some specific measurement models in which backflow may be identified in certain measurable probabilities.

description: In this contribution it is shown that small changes to the choice of cell size in the FDTD and TLM methods can have a large effect on the predicted behaviour of a microstrip filter but that the use of Pre-calculated Correction Factors (PCFs) can vastly reduce this effect and also yield more accurate answers for a specified cell size.

description: We investigate the impact of different observational effects affecting a precise and accurate measurement of the growth rate of fluctuations from the anisotropy of clustering in galaxy redshift surveys. We focus on redshift measurement errors, on the reconstruction of the underlying real-space clustering and on the apparent degeneracy existing with the geometrical distortions induced by the cosmology-dependent conversion of redshifts into distances. We use a suite of mock catalogues extracted from large N-body simulations, focusing on the analysis of intermediate, mildly non-linear scales and apply the standard linear dispersion model to fit the anisotropy of the observed correlation function. We verify that redshift errors up to ~0.2% have a negligible impact on the precision with which the specific growth rate beta can be measured. Larger redshift errors introduce a positive systematic error, which can be alleviated by adopting a Gaussian distribution function of pairwise velocities. This is, in any case, smaller than the systematic error of up to 10% due to the limitations of the linear dispersion model, which is studied in a separate paper. We then show that 50% of the statistical error budget on beta depends on the deprojection procedure through which the real-space correlation function is obtained. Finally, we demonstrate that the degeneracy with geometric distortions can in fact be circumvented. This is obtained through a modified version of the Alcock-Paczynski test in redshift-space, which successfully recovers the correct cosmology by searching for the solution that optimizes the description of dynamical redshift distortions. For a flat cosmology, we obtain largely independent, robust constraints on beta and OmegaM. In a volume of 2.4(Gpc/h)^3, the correct OmegaM is obtained with ~12% error and negligible bias, once the real-space correlation function is properly reconstructed.

description: Meta‐communities of habitat islands may be essential to maintain biodiversity in anthropogenic landscapes allowing rescue effects in  local habitat patches. To understand the species‐assembly mechanisms  and dynamics of such ecosystems, it is important to  test how local plant‐community diversity and composition is affected by spatial isolation and hence by dispersal limitation and local environmental conditions acting as filters for local species sorting. We used a system of 46 small wetlands (kettle holes)—natural small‐scale freshwater habitats rarely considered in  nature conservation policies—embedded in an  intensively managed agricultural matrix in northern Germany. We compared two types of kettle holes with distinct topographies (flatsloped, ephemeral, frequently plowed kettle holes vs. steep‐sloped, more permanent ones) and determined 254 vascular plant species within these ecosystems, as well as plant functional traits and nearest neighbor distances to other kettle holes. Differences in alpha and beta diversity between steep permanent compared with ephemeral flat kettle holes were mainly explained by species sorting and niche processes and mass effect processes in ephemeral flat kettle holes. The plant‐community composition as well as the community trait distribution in terms of life span, breeding system, dispersal ability, and longevity of seed banks significantly differed between the two habitat types. Flat ephemeral kettle holes held a higher percentage of non‐perennial plants with a more persistent seed bank, less obligate outbreeders and more species with seed dispersal abilities via animal vectors compared with steep‐sloped, more permanent kettle holes that had a higher percentage of wind‐dispersed species. In the flat kettle holes, plant‐species richness was negatively correlated with the degree of isolation, whereas no such pattern was found for the permanent kettle holes. Synthesis: Environment acts as filter shaping plant diversity (alpha and beta) and plant‐community trait distribution between steep permanent compared with ephemeral flat kettle holes supporting species sorting and niche mechanisms as expected, but we identified a mass effect in ephemeral kettle holes only. Flat ephemeral kettle holes can be regarded as meta‐ecosystems that strongly depend on seed dispersal and recruitment from a seed bank, whereas neighboring permanent kettle holes have a more stable local species diversity.

description: Australia’s Great War was both unifying and divisive. The Anzac legend that celebrated soldiers’ achievements fostered national pride and confidence, but the war widened fissures based on class, religion, and ethnicity. In particular, the debate over conscription had unleashed intense passions that lived on into the post-war era. Influenza, unemployment, and industrial strife, as well as international developments in Ireland and Russia, contributed to the tense atmosphere. By 1922, while people and governments were still grappling with the expensive problem of supporting those whose lives the war had torn apart, there were signs that the nation was entering calmer waters.
