description: Unter dem Begriff "Industrie 4.0" wurden im letzten Jahrzehnt Ansätze der Dateninfra-struktur in Produktionen entwickelt und in großem Umfang angewendet. Dennoch kann das volle Potenzial datengetriebener Analysen kaum ausgeschöpft werden, da viele Produktionsanlagen durch eine hohe Komplexität und Prozessvielfalt gekennzeichnet sind. Zudem ist die Datenmenge in der Praxis meist zu gering, um selbstlernende Me-thoden anzuwenden. Die Integration von Anwenderwissen in datengetriebenen Metho-den ist bisher nicht ganzheitlich erforscht. In dieser Dissertation werden Ansätze zur Anomalieerkennung in verschiedenen hochflexiblen Produktionsmaschinen und die In-tegration von Domänenwissen eines Anwenders vorgestellt. Während sich bestehende Methoden auf das Modelltraining von sich wiederholenden gleichen Prozessen kon-zentrieren, besteht der neuartige Ansatz dieser Arbeit darin, ein Konzept zur Fehlerer-kennung mit einer sehr geringen Datenmenge zu entwickeln. Eingriffsgrenzen sind va-riabel und lassen sich durch selbstlernende Algorithmen im Falle einer Prozess- oder Produktänderung anpassen. Die Prozessdifferenzierung basiert auf einer Prozessseg-mentierung mit Methoden der Mustererkennung. Nach der Segmentierung historischer Datenströme und der Bestimmung repräsentativer Muster werden die Segmente in On-line-Signalen wiedererkannt. Nachdem ein ähnliches Segment erkannt wurde, wird eine unüberwachte Anomalieerkennung durchgeführt. Eine Anomalie-Klassifikation mit Hilfe selbstlernender Methoden und des formalisierten Domänenwissens ermöglicht die Ausgabe von Handlungsempfehlungen für den Benutzer oder Maschinenbediener. Alle entwickelten Methoden werden an drei ausgewählten industriell relevanten Anwen-dungsbeispielen validiert. Die Methoden werden in einer App implementiert.

description: PoGOLite is a balloon-borne hard X-ray polarimeter dedicated to the study of point sources. Compton scattered events are registered using an array of plastic scintillator units to determine the polarisation of incident X-rays in the energy range 20 - 240 keV. In 2013, a near circumpolar balloon flight of 14 days duration was completed after launch from Esrange, Sweden, resulting in a measurement of the linear polarisation of the Crab emission. Building on the experience gained from this Pathfinder flight, the polarimeter is being modified to improve performance for a second flight in 2016. Such optimisations, based on Geant4 Monte Carlo simulations, take into account the source characteristics, the instrument response and the background environment which is dominated by atmospheric neutrons. This paper describes the optimisation of the polarimeter and details the associated increase in performance. The resulting design, PoGO+, is expected to improve the Minimum Detectable Polarisation (MDP) for the Crab from 19.8% to 11.1% for a 5 day flight. Assuming the same Crab polarisation fraction as measured during the 2013 flight, this improvement in MDP will allow a 5σ constrained result. It will also allow the study of the nebula emission only (Crab off-pulse) and Cygnus X-1 if in the hard state.

description: The absorption rate of low-energy, or soft, electromagnetic radiation by spherically symmetric black holes in arbitrary dimensions is shown to be fixed by conservation of energy and large gauge transformations. We interpret this result as the explicit realization of the Hawking-Perry-Strominger Ward identity for large gauge transformations in the background of a non-evaporating black hole. Along the way we rederive and extend previous analytic results regarding the absorption rate for the minimal scalar and the photon.

description: Endeavours to understand the complex interactions between society and environment have stimulated a lively debate over the prerequisites for interdisciplinarity and integrated environmental research. One highly contested issue is whether, and to what extent, interdisciplinarity can be achieved within the framework of present academic structures, considering their strong disciplinary orientation. Some scholars see a need for a fundamental reorganisa-tion of science and its links back to society, in order to be able to develop trans-disciplinary and problem-oriented knowledge. Other authors reject this position and highlight the need for strictly disciplinary research which then has to be integrated into interdisciplinary research by appropriate organisational means. Against this background, this article describes to what extent the research organisation and research practices currently applied in major German university-based environmental research programmes can be said to be interdisciplinary and integrative. The programmes were also examined to find out how different outcomes could be explained. The most important finding was that the full challenge of interdisciplinarity only becomes apparent during the actual research process. Being predominantly based on an additive form of integration of results, these research processes were multidisciplinary rather than interdisciplinary, but nevertheless produced an interdisciplinary "added value" beyond disciplinary perspectives. Variations in outcomes corresponded to differences in the organisation of the respective research processes and their management. Thus, while this study confirms the dependency of interdisciplinarity on suitable organisational structures and endeavours, it also points to the need for developing a supportive academic culture.

description: We cross-match the two currently largest all-sky photometric catalogs, mid-infrared WISE and SuperCOSMOS scans of UKST/POSS-II photographic plates, to obtain a new galaxy sample that covers 3pi steradians. In order to characterize and purify the extragalactic dataset, we use external GAMA and SDSS spectroscopic information to define quasar and star loci in multicolor space, aiding the removal of contamination from our extended-source catalog. After appropriate data cleaning we obtain a deep wide-angle galaxy sample that is approximately 95% pure and 90% complete at high Galactic latitudes. The catalog contains close to 20 million galaxies over almost 70% of the sky, outside the Zone of Avoidance and other confused regions, with a mean surface density of over 650 sources per square degree. Using multiwavelength information from two optical and two mid-IR photometric bands, we derive photometric redshifts for all the galaxies in the catalog, using the ANNz framework trained on the final GAMA-II spectroscopic data. Our sample has a median redshift of z_{med} = 0.2 but with a broad dN/dz reaching up to z>0.4. The photometric redshifts have a mean bias of |delta_z|~10^{-3}, normalized scatter of sigma_z = 0.033 and less than 3% outliers beyond 3sigma_z. Comparison with external datasets shows no significant variation of photo-z quality with sky position. Together with the overall statistics, we also provide a more detailed analysis of photometric redshift accuracy as a function of magnitudes and colors. The final catalog is appropriate for `all-sky' 3D cosmology to unprecedented depths, in particular through cross-correlations with other large-area surveys. It should also be useful for source pre-selection and identification in forthcoming surveys such as TAIPAN or WALLABY.

description: Die Beteiligung der Öffentlichkeit an umweltrelevanten Entscheidungen und Verfahren wird in den letzten Jahren verstärkt vom EU- und Völkerrecht eingefordert. Populärster Ausdruck dieser Bemühungen ist die Aarhus-Konvention von 1998. Trotz durch EU-Umweltrichtlinien verbindlich gewordener Implementationsvorgaben kann eine Fallstudie der Bundesländer Niedersachsen, Hamburg und Bremen ein Durchschlagen des internationalen Beteiligungsausbaus auf regionale Ebene jedoch nicht bestätigen. Während Hamburg und Niedersachsen die umweltrechtlichen Partizipationsvorgaben im Untersuchungszeitraum seit 2003 sehr restriktiv umsetzten und ihr Beteiligungsnivau sogar abbauten, erweiterte alleine Bremen bedingt richtlinienkonform die Beteiligung in Umweltbelangen. Als Ursachen dieser überraschenden Entwicklung auf Landesebene können im Sinne der Misfit-These eine von den internationalen Vorstellungen abweichende deutsche Beteiligungskultur und die parteipolitische Abhängigkeit der Beteiligungspolitik ausgemacht werden. Hinzu kommt möglicherweise eine auch regional differenzierte Beteiligungskultur, die in Bremen vergleichsweise positiv ausfällt.

description: We have used Resonant Inelastic X-ray Scattering (RIXS) and dynamical susceptibility calculations to study the magnetic excitations in NaFe$_{1-x}$Co$_x$As (x = 0, 0.03, and 0.08). Despite a relatively low ordered magnetic moment, collective magnetic modes are observed in parent compounds (x = 0) and persist in optimally (x = 0.03) and overdoped (x = 0.08) samples. Their magnetic bandwidths are unaffected by doping within the range investigated. High energy magnetic excitations in iron pnictides are robust against doping, and present irrespectively of the ordered magnetic moment. Nevertheless, Co doping slightly reduces the overall magnetic spectral weight, differently from previous studies on hole-doped BaFe$_{2}$As$_{2}$, where it was observed constant. Finally, we demonstrate that the doping evolution of magnetic modes is different for the dopants being inside or outside the Fe-As layer.

description: Central galaxies make up the majority of the galaxy population, including the majority of the quiescent population at $\mathcal{M}_* > 10^{10}\mathrm{M}_\odot$. Thus, the mechanism(s) responsible for quenching central galaxies plays a crucial role in galaxy evolution as whole. We combine a high resolution cosmological $N$-body simulation with observed evolutionary trends of the "star formation main sequence," quiescent fraction, and stellar mass function at $z < 1$ to construct a model that statistically tracks the star formation histories and quenching of central galaxies. Comparing this model to the distribution of central galaxy star formation rates in a group catalog of the SDSS Data Release 7, we constrain the timescales over which physical processes cease star formation in central galaxies. Over the stellar mass range $10^{9.5}$ to $10^{11} \mathrm{M}_\odot$ we infer quenching e-folding times that span $1.5$ to $0.5\; \mathrm{Gyr}$ with more massive central galaxies quenching faster. For $\mathcal{M}_* = 10^{10.5}\mathrm{M}_\odot$, this implies a total migration time of $\sim 4~\mathrm{Gyrs}$ from the star formation main sequence to quiescence. Compared to satellites, central galaxies take $\sim 2~\mathrm{Gyrs}$ longer to quench their star formation, suggesting that different mechanisms are responsible for quenching centrals versus satellites. Finally, the central galaxy quenching timescale we infer provides key constraints for proposed star formation quenching mechanisms. Our timescale is generally consistent with gas depletion timescales predicted by quenching through strangulation. However, the exact physical mechanism(s) responsible for this still remain unclear.

description: The Reissner-Nordström black hole solution in a generic cosmological constant background in the the context of Rastall gravity is obtained. It is shown that the cosmological constant arises naturally from the consistency of the non-vacuum field equations of the Rastall theory for a spherical symmetric spacetime, rather than its {\it ad-hoc} introduction in the usual Einstein and Einstein-Maxwell field equations. The usual Reissner-Nordström, Schwarzschild and Schwarzschild-(anti)de Sitter black hole solutions in the framework of this theory are also addressed as the special independent subclasses of the obtained general solution.

description: Geodesic acoustic modes (GAMs) are oscillations of the electric field whose importance in tokamak plasmas is due to their role in the regulation of turbulence. The linear collisionless damping of GAMs is investigated here by means of analytical theory and numerical simulations with the global gyrokinetic particle-in-cell code ORB5. The combined effect of the phase mixing and Landau damping is found to quickly redistribute the GAM energy in phase-space, due to the synergy of the finite orbit width of the passing ions and the cascade in wave number given by the phase mixing. When plasma parameters characteristic of realistic tokamak profiles are considered, the GAM decay time is found to be an order of magnitude lower than the decay due to the Landau damping alone, and in some cases of the same order of magnitude of the characteristic GAM drive time due to the nonlinear interaction with an ITG mode. In particular, the radial mode structure evolution in time is investigated here and reproduced quantitatively by means of a dedicated initial value code and diagnostics.

The magnetorotational instability in debris-disc gas

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Debris discs are commonly swathed in gas which can be observed in UV, in fine structure lines in FIR, and in resolved maps of CO emission. Carbon and oxygen are overabundant in such gas, but it is severely depleted in hydrogen. As a consequence, its ionisation fraction is remarkably high, suggesting magnetohydrodynamic (MHD) processes may be important. In particular, the gas may be subject to the magnetorotational instability (MRI), and indeed recent modelling of $β$ Pictoris requires an anomalous viscosity to explain the gas's observed radial structure. In this paper we explore the possibility that the MRI is active in debris-disc gas and responsible for the observed mass transport. We find that non-ideal MHD and dust-gas interactions play a subdominant role, and that linear instability is viable at certain radii. However, owing to low gas densities, the outer parts of the disc could be stabilised by a weak ambient magnetic field, though it is difficult to constrain such a field. Even if the MRI is stabilised by too strong a field, a magnetocentrifugal wind may be launched in its place and this could lead to equivalent (non-turbulent) transport. Numerical simulations of the vertically stratified MRI in conditions appropriate to the debris disc gas should be able to determine the nature of the characteristic behaviour at different radii, and decide on the importance of the MRI (and MHD more generally) on the evolution of these discs.

description: We present a timing analysis of two Rossi X-ray Timing Explorer observations of the microquasar GRS 1915+105 during the heartbeat state. The phase-frequency-power maps show that the intermediate-frequency aperiodic X-ray variability weakens as the source softens in the slow rise phase, and when the quasi-periodic oscillation disappears in the rise phase of the pulse of the double-peaked class its sub-harmonic is still present with a hard phase lag. In the slow rise phase, the energy-frequency-power maps show that most of the aperiodic variability is produced in the corona, and may also induce the aperiodic variability observed at low energies from an accretion disk, which is further supported by the soft phase lag especially in the intermediate-frequency range (with a time delay up to 20 ms). In the rise phase of the pulse, the low-frequency aperiodic variability is enhanced significantly and there is a prominent hard lag (with a time delay up to 50 ms), indicating that the variability is induced by extension of the disk toward small radii as implied by the increase in flux and propagates into the corona. However, during the hard pulse of the double-peaked class, the variability shows no significant lag, which may be attributed to an optically thick corona. These timing results are generally consistent with the spectral results presented by Neilsen et al. (2011, 2012) which indicated that the slow rise phase corresponds to a local Eddington limit and the rise phase of the pulse corresponds to a radiation pressure instability in the disk.

description: Observations suggest that there is a significant fraction of O-stars in the field of the Milky Way that appear to have formed in isolation or in low mass clusters ($$8 $M_\odot$) young stellar objects (MYSOs) in the Large Magellanic Cloud (LMC). The observations show that while these MYSOs are remote from other MYSOs, OB associations, and even from known giant molecular clouds, they are actually not isolated at all. Imaging reveals $\sim$100 to several hundred pre--main-sequence (PMS) stars in the vicinity of each MYSO. These previously undetected PMS stars form prominent compact clusters around the MYSOs, and in most cases they are also distributed sparsely across the observed regions. Contrary to what previous high-mass field star studies show, these observations suggest that high-mass stars may not be able to form in clusters with masses less than 100 $M_\odot$. If these MYSOs are indeed the best candidates for isolated high-mass star formation, then the lack of isolation is at odds with random sampling of the IMF. Moreover, while isolated MYSOs may not exist, we find evidence that isolated clusters containing O-stars can exist, which in itself is rare.

description: There has been an increased focus on the integration of practices into physics curricula, with a particular emphasis on integrating computation into the undergraduate curriculum of scientists and engineers. In this paper, we present a university-level, introductory physics course for science and engineering majors at Michigan State University (MSU) called ${\rm P}^3$ (Projects and Practices in Physics) that is centered around providing introductory physics students with the opportunity to appropriate various science and engineering practices. The ${\rm P}^3$ design integrates computation with analytical problem solving and is built upon a curriculum foundation of problem-based learning, the principles of constructive alignment and the theoretical framework of community of practice. The design includes an innovative approach to computational physics instruction, instructional scaffolds, and a unique approach to assessment that enables instructors to guide students in the development of the practices of a physicist. We present the very positive student related outcomes of the design gathered via attitudinal and conceptual inventories and research interviews of students' reflecting on their experiences in the ${\rm P}^3$ classroom.

Skyrmions are whirl-like spin vortices that have received great theoretical interest because of their non-trivial spin topology and that are also considered as basic entities for new data-storage technologies. Interestingly, we found that the orbitally ordered phase shows sizable ferroelectric polarization and that excess spin-driven polarizations appear in all magnetic phases, including the skyrmion-lattice phase. Hence, GaV4S8 shows simultaneous magnetic and polar order and belongs to the class of multiferroics, materials that attracted enormous attention in recent years. Here, we summarize the existing experimental information on the magnetic, electronic, and dielectric properties of GaV4S8. By performing detailed magnetic susceptibility, resistivity, specific heat, and dielectric experiments, we complement the low-temperature phase diagram. Specifically, we show that the low-temperature and low-field ground state of GaV4S8 seems to have a more complex spin configuration than purely collinear ferromagnetic spin order. In addition, at the structural Jahn-Teller transition the magnetic exchange interaction changes from antiferromagnetic to ferromagnetic. We also provide experimental evidence that the vanadium V4 clusters in GaV4S8 can be regarded as molecular units with spin 1/2. However, at high temperatures deviations in the susceptibility show up, indicating that either the magnetic moments of the vanadium atoms fluctuate independently or excited states of the V4 molecule become relevant.

description: It is of key importance to identify innovative business ideas in an early stage, so that funding resources can be adequately allocated according to their economic potential. Traditional indicators do not reliably discriminate business ideas with high degree of innovativeness and high incorporation chances from those with low degree of innovativeness and low incorporation prospects. Therefore, this paper examines the content of business idea descriptions to improve the estimations of the incorporation probability. The paper aims to answer two questions: 1) Are there differences in topic prevalence in innovative and non-innovative business ideas?, and 2) How does the composition of topics related to a business idea influence its incorporation probability? Structural topic modeling and classification tree analysis are applied on business idea descriptions from a competition in Bremen, Germany, from 2003 until 2019. The results show that business idea descriptions are a rich source of information to identify both innovative ideas and those with higher incorporation prospects.

description: We present late-time optical spectroscopy taken with the Large Binocular Telescope's Multi-Object Double Spectrograph, late-time SWIFT UVOT and XRT observations, as well as improved ASAS-SN pre-discovery limits on the nearby (d=90.3 Mpc, z=0.0206) tidal disruption event (TDE) ASASSN-14li. The late-time optical spectra show H$α$ emission well in excess of that seen in the SDSS host galaxy spectrum, indicating that the processes powering the luminous flares associated with TDEs can operate for several hundreds of days. The SWIFT observations reveal the presence of lingering apparently thermal UV (T$_{\rm UV} \sim 3.5\times10^4$ K) and X-ray (T$_{\rm X} \sim 7\times10^5$ K) emission. The characteristic temperatures evolve by, at most, a factor of $\sim2$ over the 600 day follow-up campaign. The X-ray, UV, and H$α$ luminosities evolve roughly in tandem and at a rate that is consistent with a power-law decay at late times. This behavior is in stark contrast with the majority of optically discovered TDEs, which are X-ray faint and evolve on shorter timescales. Finally we address how the unique properties of ASASSN-14li can be used to probe the relationship between the TDE rate and host galaxy properties.

Subjects: subject: Entrepreneurship
subject: 330

description: This issue covers rich entrepreneurship-related topics in variety. The first article, "Absorptive Capacity in the Context of Accelerators - Gaining Competitive Advantages through Knowledge Absorption" illuminates the role of knowledge absorption for accelerators, which represent a novel form of entrepreneurial support organizations. The second article, "Towards Understanding Culture in Entrepreneurial Ecosystems", deals with entrepreneurial ecosystems a "hot" topic, which has recently received rapidly growing attention from both regional policymakers and entrepreneurship scholars. By applying the framework of organizational culture, this author group investigates how we can understand the cultural aspect of entrepreneurial ecosystems. The third paper, "Entrepreneurs I Poverty through the Lens of Bricolage", takes a closer look at the way entrepreneurs in penurious environments can respond to resource constraints, which emerge through three different types of poverty: social, psychological, and political poverty. The fourth article is "Student Entrepreneurship: An Application of the Theory of Planned Behavior" observes students' entrepreneurial activities by paying particular attention to the context in which students are embedded and how they influence their attitude, subjective norm, and perceived behavioral control. The final article, "Resources of Transnational Entrepreneurs Achieving Competitive Advantages", analyzes entrepreneurs who conduct business in transitional settings from the resource-based view. They highlight three types of resources, networks, experience, and knowledge, which transnational entrepreneurs can build through their dual embeddedness in their country of origin and residence.

description: We report the synthesis of a novel isotope engineered $^{13}{\rm C}$--$^{12}{\rm C}$ heteronuclear nanostructure: single-wall carbon nanotubes made of $^{13}{\rm C}$ enriched clusters which are embedded in natural carbon regions. The material is synthesized with a high temperature annealing from $^{13}{\rm C}$ enriched benzene and natural ${\rm C}_{60}$, which are co-encapsulated inside host SWCNTs in an alternating fashion. The Raman 2D line indicates that the $^{13}{\rm C}$ isotopes are not distributed uniformly in the inner tubes. A semi-empirical method based modeling of the Raman modes under $^{13}{\rm C}$ isotope enrichment shows that experimental data is compatible with the presence of $^{13}{\rm C}$ rich clusters which are embedded in a natural carbon containing matrix. This material may find applications in quantum information processing and storage using nuclear spins as qubits.

description: The use of temporal logics has long been recognised as a fundamental approach to the formal specification and verification of reactive systems. In this paper, we take on the problem of automatically verifying a temporal property, given by a CTL formula, for a given (possibly infinite-state) program. We propose a method based on encoding the problem as a set of Horn constraints. The method takes a program, modeled as a transition system, and a property given by a CTL formula as input. It first generates a set of forall-exists quantified Horn constraints and well-foundedness constraints by exploiting the syntactic structure of the CTL formula. Then, the generated set of constraints are solved by applying an off-the-shelf Horn constraints solving engine. The program is said to satisfy the property if and only if the generated set of constraints has a solution. We demonstrate the practical promises of the method by applying it on a set of challenging examples. Although our method is based on a generic Horn constraint solving engine, it is able to outperform state-of-art methods specialised for CTL verification.

description: During early development, the establishment of gradients of transcriptional factors determines the patterning of cell fates. The case of Bicoid (Bcd) in {\it Drosophila melanogaster} embryos is well documented and studied. There are still controversies as to whether {\it SDD} models in which Bcd is {\it Synthesized} at one end, then {\it Diffuses} and is {\it Degraded} can explain the gradient formation within the timescale observed experimentally. The Bcd gradient is observed in embryos that express a Bicoid-eGFP fusion protein (Bcd-GFP) which cannot differentiate if Bcd is freely diffusing or bound to immobile sites. In this work we analyze an {\it SDID} model that includes the {\it Interaction} of Bcd with binding sites. Using previously determined biophysical parameters we find that this model can explain the gradient formation within the experimentally observed time. Analyzing the differences between the free and bound Bcd distributions we observe that the latter spans over a longer lengthscale. We conclude that deriving the lengthscale from the distribution of Bcd-GFP can lead to an overestimation of the gradient lengthscale and of the degree of cooperativity that explains the distribution of the protein Hunchback whose production is regulated by Bcd.

The Importance of Subjective Measurements in Child and Youth Well-Being Studies

description: Considering changing political landscapes and societies’ needs in Europe, we argue for establishing a European longitudinal study on child and youth well-being revealing new trends in a longterm perspective. As a part of an international research team, we worked on preparing this study, called EuroCohort. By doing so, we were concerned with choosing theoretical as well as measurement concepts to capture (child and youth) well-being in a way that is needed in order to shed light on Europe’s future generation. In this paper, we present our considerations on suitable theoretical approaches and their interrelation to measurement concepts. Thereby, our focus lies on the question how subjective measurement concepts can provide added value to child and youth well-being surveys. Although the relevance of subjective measures of well-being is recognised, so far hardly any comparative and longitudinal studies have incorporated corresponding indicators. This paper emphasises the need for implementing subjective measurements in studies on child and youth well-being, respecting their value for different well-being domains.
