description: Der technologische Wandel, der in den letzten Jahren stattgefunden hat, führte zu einer neuen industriellen Revolution. Die vierte industrielle Revolution baut auf cyber-physischen Systemen auf, die mechanische Komponenten durch die Internetkommunikation miteinander vernetzt und dadurch die Steuerung von komplexen Systemen, wie Fertigungsanlagen, ermöglicht. Dies hat zu einem Fortschritt in der Industrie geführt und den Möglichkeiten in der Produktion. Dem gegenüber steht der altbewährte Lean Production Ansatz, der bereits seit 1970 in den produzierenden Unternehmen dieser Welt, ein fester Bestandteil ist. Darin enthalten sind Methoden, die zum Beispiel zur Verschwendungsminimierung, Prozessverschlankung sowie Produktionssteuerung beitragen. Obwohl die beiden Produktionsphilosophien auf den ersten Blick nicht in Korrelation zueinanderstehen, sind sie in der realen Produktionswelt kaum voneinander trennbar. Sie queren sich nicht nur in ihren Prinzipien und Leitgedanken, sondern auch in den Methoden selbst. Dabei können sie in vielen Punkten als ergänzend angesehen werden und teilweise auch als aufeinander aufbauend. Der Hauptteil der vorliegenden Arbeit beschäftigt sich damit, inwiefern Industrie 4.0 einen Einfluss auf die altbewährten Lean Methoden hat und wie diese zwei Themen im Verhältnis zueinanderstehen. Dabei werden die Grundprinzipien, die hinter diesen beiden Begriffen stehen erläutert und zueinander in Relation gestellt. Ebenfalls findet ein direkter Methodenvergleich statt, bei dem ausgewählte Lean Methoden mit Industrie 4.0 verglichen werden. In den Kapiteln werden nicht nur die Gemeinsamkeiten behandelt, sondern natürlich auch die Gegensätze, die diese zwei Prinzipien innehaben. Im anschließenden Kapitel wird weiters definiert, ob Lean Management die Voraussetzung für Investitionen in Industrie 4.0 darstellt, oder ob Industrie 4.0 diverse Lean Methoden sogar obsolet macht. Den Abschluss der Arbeit bildet eine Analyse des neuen Begriffes Lean 4.0, der bereits in diversen Publikationen vorgestellt wurde. Ebenfalls werden noch drei Modelle vorgestellt, die einen Leitfaden für die Einführung von Industrie 4.0 darstellen und eine eindeutige Stellungnahme dazu nehmen, ob Lean die Voraussetzung für eine erfolgreiche Einführung von Industrie 4.0 im Unternehmen ist.
René Girard, Unlikely Apologist: Mimetic Theory and Fundamental Theology
Creators: name: Kaplan, Grant
Publisher: name: University of Notre Dame
Year: 2023

description: Since the late 1970s, theologians have been attempting to integrate mimetic theory into different fields of theology, yet a distrust of mimetic theory persists in some theological camps. In _René Girard, Unlikely Apologist: Mimetic Theory and Fundamental Theology_, Grant Kaplan brings mimetic theory into conversation with theology both to elucidate the relevance of mimetic theory for the discipline of fundamental theology and to understand the work of René Girard within a theological framework. Rather than focus on Christology or atonement theory as the locus of interaction between Girard and theology, Kaplan centers his discussion on the apologetic quality of mimetic theory and the impact of mimetic theory on fundamental theology, the subdiscipline that grew to replace apologetics. His book explores the relation between Girard and fundamental theology in several keys. In one, it understands mimetic theory as a heuristic device that allows theological narratives and positions to become more intelligible and, by so doing, makes theology more persuasive. In another key, Kaplan shows how mimetic theory, when placed in dialogue with particular theologians, can advance theological discussion in areas where mimetic theory has seldom been invoked. On this level the book performs a dialogue with theology that both revisits earlier theological efforts and also demonstrates how mimetic theory brings valuable dimensions to questions of fundamental theology. © University of Notre Dame Copyright for most content is held by The University of Notre Dame.

description: We study the routing of quantum information in parallel on multi-dimensional networks of tunable qubits and oscillators. These theoretical models are inspired by recent experiments in superconducting circuits using Josephson junctions and resonators. We show that perfect parallel state transfer is possible for certain networks of harmonic oscillator modes. We further extend this to the distribution of entanglement between every pair of nodes in the network, finding that the routing efficiency of hypercube networks is both optimal and robust in the presence of dissipation and finite bandwidth.

description: Im Zusammenhang mit Industrie 4.0 wurde der Digital Twin in den letzten Jahren zu einem der Schlagwörter für die Forscher und Forscherinnen wie auch für einige Unternehmen. Wie oft vermutet, ist der Digital Twin aber nicht nur eine digitale Abbildung eines realen Objektes. Im Zusammenhang mit Digital Twins ist auch die Rede von der Sicherstellung der Datenintegration über den kompletten Produkt- sowie Anlagenlebenszyklus oder der Simulation verschiedenster Szenarien. Die Zielsetzung des Digital Twin Konzepts ist die bessere Prognose des Verhaltens von Produkten und Fertigungsanlagen und die damit verbundene Senkung von Qualitätsproblemen und -kosten. Dies birgt potenziell auch Konsequenzen für das Qualitätsmanagement in den produzierenden Unternehmen. Der Digital Twin als neuer Trend trifft somit auf eine etablierte Domäne, denn Qualitätsmanagement ist seit Jahrzehnten ein fester Bestandteil in der Praxis. Nebst der gesonderten Betrachtung beider Themengebiete gilt es die Potenziale und die Herausforderungen für die Implementierung und Anwendung der Digital Twins im Qualitätsmanagement anhand der Literaturrecherche und -synthese zu ermitteln. Die Potenziale und Herausforderungen sind an den Beispielen der echtzeitnahen Qualitätsregelkreise und der auf Prognosen gestützten und verkürzten Produkt- und Prozessplanung aufzuzeigen.
description: The Digital Twin has become one of the buzzwords in the context of Industry 4.0 for many researchers as well as companies in the recent years. The Digital Twin is often considered to be only a digital representation of a physical object but it is more than that. Besides the digital representation the Digital Twin should ensure the data integration or perform simulation of various scenarios. The main goal of the Digital Twin concept is the improved capability in the behavior prediction of the products and production facilities. Due to the application of Digital Twins the quality issues and the related costs are expected to be reduced. At the same time the Digital Twins are very likely to cause consequences for the quality management in manufacturing companies. The quality management is an established domain in the companies since several decades and it is now faced with the upcoming trend of Digital Twins. Therefore, the two topics must be separately explored and considered as a starting point. Finally, the potentials and challenges for the implementation and application of Digital Twins in quality management must be determined based on literature research and synthesis. The findings are illustrated by the examples of the close-to-real-time quality control circuit and the prediction-based and faster product and process planning.

description: We present a computation of the O(alpha_s) QCD corrections to W^\pm Z γproduction at the Large Hadron Collider. The photon is considered as real, and we include full leptonic decays for the W and Z bosons. Based on the structure of the VBFNLO program package, we obtain numerical results through a fully flexible Monte Carlo program, which allows to implement general cuts and distributions of the final-state particles. The NLO QCD corrections are sizable and strongly exceed the theory error obtained by a scale variation of the leading-order result. Also, the shapes of relevant observables are significantly altered.

description: Unternehmen der Logistikbranche sehen sich zunehmend mit geschäftsgefährdenden Herausforderungen konfrontiert. Veränderte gesellschaftliche Ansprüche, neue Technologien und Konkurrenz, sowie diverse Makrorisiken setzen die Branche unter Druck. Um frühzeitig adäquate Lösungsansätze auf zukünftige Entwicklungen finden zu können, bedarf es einer langfristig ausgerichteten unternehmerischen Sichtweise. Diese Weitsicht ist bei einer Mehrzahl von Logistikunternehmen jedoch bisher nicht vorhanden. Daher beschäftigt sich die Masterarbeit mit der Beantwortung folgender Fragestellung: „Welche Methoden der strategischen Langfristprognostik sind in der Logistik und dem Supply-Chain-Management besonders geeignet und ist die Corporate Foresight eine praktikable Option?“ Für die Beantwortung der Fragestellung wird ein theoretisch-konzeptioneller Ansatz verfolgt. Der Schwerpunkt der Arbeit liegt in der Analyse der Logistikbranche, sowie in der Aufarbeitung bestehender Literatur hinsichtlich existierenden Prognosemethoden, Gründe deren Scheiterns in der betrieblichen Praxis und dem Corporate Foresight. Die daraus erlangten Erkenntnisse werden auf die Logistikbranche transferiert, um Logistikunternehmen mögliche Ansatzpunkte und Denkanstöße für die Einführung bzw. Einnahme einer strategischen Weitsicht zu liefern.
description: Logistic companies are facing an increasing amount of business endangering challenges. Changing expectations of society, the emergence of novel technologies and the appearance of new competitors, plus a high variety of macro risks are pressurizing the whole industry. To cope with these challenges, companies must find suitable solution for which they have to take a long-term oriented perspective. However, such foresight is missing in the majority of businesses in the logistic industry. As a result, the thesis at hand is dealing with the following research question: “Which methods for strategic long-term forecasting are most suitable for the logistic industry and the supply chain management and is the corporate foresight a viable option?” To answer the introduced research question, a theoretical-conceptual approach will be used. The thesis focuses on analyzing the logistic industry and the reconditioning of existing literature, regarding the methods and common mistakes of forecasting. Furthermore, the approach of corporate foresight is analyzed. The outcomes derived throughout the literature will then be transferred to the logistic industry in order to provide valuable insights and new food for thought for corporate foresight initiatives.

description: The Aharonov-Bohm effect including spin-noncommutative effects is considered. At linear order in $θ$, the magnetic field is gauge invariant although spatially strongly anisotropic. Despite this anisotropy, the Schrödinger-Pauli equation is separable through successive unitary transformations and the exact solution is found. The scattering amplitude is calculated and compared with the usual case. In the noncommutative Aharonov-Bohm case the differential cross section is independent of $θ$.

description: We present an analysis of elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe), and focus initially on 14 PNe in the Small Magellanic Cloud (SMC). We derived the abundances from a combination of deep, high dispersion optical spectra, as well as mid-infrared (IR) spectra from the Spitzer Space Telescope. A detailed comparison with prior SMC PN studies shows that significant variations among authors of relative emission line flux determinations lead to systematic discrepancies in derived elemental abundances between studies that are >~0.15 dex, in spite of similar analysis methods. We used ionic abundances derived from IR emission lines, including those from ionization stages not observable in the optical, to examine the accuracy of some commonly used recipes for ionization correction factors (ICFs). These ICFs, which were developed for ions observed in the optical and ultraviolet, relate ionic abundances to total elemental abundances. We find that most of these ICFs work very well even in the limit of substantially sub-Solar metallicities, except for PNe with very high ionization. Our abundance analysis shows enhancements of He and N that are predicted from prior dredge-up processes of the progenitors on the AGB, as well as the well known correlations among O, Ne, S, and Ar that are little affected by nucleosynthesis in this mass range. We identified MG_8 as an interesting limiting case of a PN central star with a ~3.5 M_sun progenitor in which hot-bottom burning did not occur in its prior AGB evolution. We find no evidence for O depletion in the progenitor AGB stars via the O-N cycle, which is consistent with predictions for lower-mass stars. We also find low S/O ratios relative to SMC H_II regions, with a deficit comparable to what has been found for Galactic PNe.

The role of lipoproteins on selected functions relevant to Alzheimer's Disease in human brain perivascular cells
Creators: name: Soo, Sonja Kar Yee

Year: 2019

description: Alzheimer‘s Disease (AD) is a progressive neurodegenerative disease that affects millions of people world-wide. It is characterized by amyloid plaques and neurofibrillary tangles in the brain. Many AD patients also show loss of cerebrovascular integrity, which is thought to lead to decreased capillary flow, neuronal injury and impaired clearance of amyloid beta. Since apolipoprotein E (apoE) and high density lipoprotein (HDL) show many beneficial effects in the vasculature in the body, we aimed to test the effects of these lipoproteins on primary human perivascular cells in the brain. We found that pharmacologically increasing apoE levels with GW3965 in a scratch-wound assay was not associated with changes in pericyte migration. Interestingly, we found that Axl inhibitor A1 slowed pericyte migration without showing changes in secreted apoE levels, suggesting an apoE-independent pathway for pericyte migration. We also tested whether HDL can attenuate the CypA-NFκB-MMP9 inflammatory pathway associated with apoE4 pericytes, but failed to observe the activation of this inflammatory pathway in our pericytes. Lastly, we found that when macrophages were treated with HDL, Aβ phagocytosis was not changed. Moreover, there were donor differences in the inflammatory response of macrophages to Aβ, making consistent observations difficult. Taken together, we did not show beneficial effects of lipoproteins on perivascular cell function in the context of AD.

description: Double-diffusive instabilities are often invoked to explain enhanced transport in stably-stratified fluids. The most-studied natural manifestation of this process, fingering convection, commonly occurs in the ocean's thermocline and typically increases diapycnal mixing by two orders of magnitude over molecular diffusion. Fingering convection is also often associated with structures on much larger scales, such as thermohaline intrusions, gravity waves and thermohaline staircases. In this paper, we present an exhaustive study of the phenomenon from small to large scales. We perform the first three-dimensional simulations of the process at realistic values of the heat and salt diffusivities and provide accurate estimates of the induced turbulent transport. Our results are consistent with oceanic field measurements of diapycnal mixing in fingering regions. We then develop a generalized mean-field theory to study the stability of fingering systems to large-scale perturbations, using our calculated turbulent fluxes to parameterize small-scale transport. The theory recovers the intrusive instability, the collective instability, and the gamma-instability as limiting cases. We find that the fastest-growing large-scale mode depends sensitively on the ratio of the background gradients of temperature and salinity (the density ratio). While only intrusive modes exist at high density ratios, the collective and gamma-instabilities dominate the system at the low density ratios where staircases are typically observed. We conclude by discussing our findings in the context of staircase formation theory.

The scaling of the algorithm towards the continuum is not changed. In particular, the effect of the topological modes on the autocorrelation times is studied.

Protein phase separation by the ABC transporter Rv1747 of Mycobacterium tuberculosis
Creators: name: Heinkel, Florian
Publisher: name: University of British Columbia
Year: 2020

description: The Mycobacterium tuberculosis ABC transporter Rv1747 is a putative exporter of cell wall biosynthesis intermediates. Rv1747 has a cytoplasmic regulatory module consisting of two pThr-interacting Forkhead-associated (FHA) domains connected by a conformationally disordered linker with two phospho-acceptor threonines (pThr). In chapter 2, I report the structures of FHA-1 and FHA-2 determined by X-ray crystallography and NMR spectroscopy, respectively. Relative to the canonical 11-strand beta-sandwich FHA domain fold of FHA-1, FHA-2 is circularly permuted and lacking one beta-strand. Nevertheless, the two share a conserved pThr-binding cleft. FHA-2 is less stable and more dynamic than FHA-1, yet binds model pThr peptides with moderately higher affinity (~ 50 uM versus 500 uM equilibrium dissociation constants). Based on NMR relaxation and chemical shift perturbation measurements, when joined within a polypeptide chain, either FHA domain can bind either linker pThr to form intra- and intermolecular complexes. Protein phase separation has been recently shown to be a fundamental mechanism underlying the clustering of some proteins at the eukaryotic cell membrane. In chapter 3, I show that upon multi-site phosphorylation of the linker by several Mtb serine/threonine protein kinases including PknF, the isolated regulatory module readily multimerizes and phase separates into dynamic liquid droplets with diagnostic properties similar to those exhibited by eukaryotic proteins. The process is reversed by the sole Mtb serine/threonine phosphatase PstP. In the absence of phosphorylation, the Rv1747 regulatory module can still undergo phase separation, albeit at higher protein concentrations and into droplets with more fluid properties. This points to a synergy between specific FHA-pThr binding and additional weak association of the ID linker and/or the FHA domains leading to the pre-requisite multivalent interactions for demixing. Droplet formation of the regulatory module was replicated in a pseudo-two-dimensional system on model supported lipid bilayers. Potential clusters of Rv1747 were also detected in Mtb using ultra-high resolution Direct Stochastic Reconstruction Microscopy (dSTORM). This is the first reported example of phase separation by both a bacterial protein and an ABC transporter, and suggests possible mechanisms for the regulation of Rv1747 within Mtb. I hypothesize that the tunable, phosphorylation-dependent multimerization described here regulates Rv1747 transporter activity.
Monte Carlo simulations of the Nickel K$α$ fluorescent emission line in a toroidal geometry

description: We present new results from Monte Carlo calculations of the flux and equivalent width (EW) of the Ni Kalpha fluorescent emission line in the toroidal X-ray reprocessor model of Murphy & Yaqoob (2009, MNRAS, 397, 1549). In the Compton-thin regime, the EW of the Ni Kalpha line is a factor of ~22 less than that of the Fe Kalpha line but this factor can be as low as ~6 in the Compton-thick regime. We show that the optically-thin limit for this ratio depends only on the Fe to Ni abundance ratio, it being independent of the geometry and covering factor of the reprocessor, and also independent of the shape of the incident X-ray continuum. We give some useful analytic expressions for the absolute flux and the EW of the Ni Kalpha line in the optically-thin limit. When the reprocessor is Compton-thick and the incident continuum is a power-law with a photon index of 1.9, the Ni Kalpha line EW has a maximum value of ~3 eV and ~250 eV for non-intercepting and intercepting lines-of-sight respectively. Larger EWs are obtained for flatter continua. We have also studied the Compton shoulder of the Ni Ka line and find that the ratio of scattered to unscattered flux in the line has a maximum value of 0.26, less than the corresponding maximum for the Fe Kalpha line. However, we find that the shape of the Compton shoulder profile for a given column density and inclination angle of the torus is similar to the corresponding profile for the Fe Ka line. Our results will be useful for interpreting X-ray spectra of active galactic nuclei (AGNs) and X-ray binary systems in which the system parameters are favorable for the Ni Kalpha line to be detected.

description: In the bi-dimensional parameter space of driven oscillators, shrimp-shaped periodic windows are immersed in chaotic regions. For two of these oscillators, namely, Duffing and Josephson junction, we show that a weak harmonic perturbation replicates these periodic windows giving rise to parameter regions correspondent to periodic orbits. The new windows are composed of parameters whose periodic orbits have periodicity and pattern similar to stable and unstable periodic orbits already existent for the unperturbed oscillator. These features indicate that the reported replicate periodic windows are associated with chaos control of the considered oscillators.

description: Recently, several complex network approaches to time series analysis have been developed and applied to study a wide range of model systems as well as real-world data, e.g., geophysical or financial time series. Among these techniques, recurrence-based concepts and prominently $ε$-recurrence networks, most faithfully represent the geometrical fine structure of the attractors underlying chaotic (and less interestingly non-chaotic) time series. In this paper we demonstrate that the well known graph theoretical properties local clustering coefficient and global (network) transitivity can meaningfully be exploited to define two new local and two new global measures of dimension in phase space: local upper and lower clustering dimension as well as global upper and lower transitivity dimension. Rigorous analytical as well as numerical results for self-similar sets and simple chaotic model systems suggest that these measures are well-behaved in most non-pathological situations and that they can be estimated reasonably well using $ε$-recurrence networks constructed from relatively short time series. Moreover, we study the relationship between clustering and transitivity dimensions on the one hand, and traditional measures like pointwise dimension or local Lyapunov dimension on the other hand. We also provide further evidence that the local clustering coefficients, or equivalently the local clustering dimensions, are useful for identifying unstable periodic orbits and other dynamically invariant objects from time series. Our results demonstrate that $ε$-recurrence networks exhibit an important link between dynamical systems and graph theory.

description: Regions of the ocean's thermocline unstable to salt fingering are often observed to host thermohaline staircases, stacks of deep well-mixed convective layers separated by thin stably-stratified interfaces. Decades after their discovery, however, their origin remains controversial. In this paper we use 3D direct numerical simulations to shed light on the problem. We study the evolution of an analogous double-diffusive system, starting from an initial statistically homogeneous fingering state and find that it spontaneously transforms into a layered state. By analysing our results in the light of the mean-field theory developed in Paper I, a clear picture of the sequence of events resulting in the staircase formation emerges. A collective instability of homogeneous fingering convection first excites a field of gravity waves, with a well-defined vertical wavelength. However, the waves saturate early through regular but localized breaking events, and are not directly responsible for the formation of the staircase. Meanwhile, slower-growing, horizontally invariant but vertically quasi-periodic gamma-modes are also excited and grow according to the gamma-instability mechanism. Our results suggest that the nonlinear interaction between these various mean-field modes of instability leads to the selection of one particular gamma-mode as the staircase progenitor. Upon reaching a critical amplitude, this progenitor overturns into a fully-formed staircase. We conclude by extending the results of our simulations to real oceanic parameter values, and find that the progenitor gamma-mode is expected to grow on a timescale of a few hours, and leads to the formation of a thermohaline staircase in about one day with an initial spacing of the order of one to two metres.

description: Close interactions and mass transfer in binary stars can lead to the formation of many different exotic stellar populations, but detailed modeling of mass transfer is a computationally challenging problem. Here, we present an alternate Smoothed Particle Hydrodynamics approach to the modeling of mass transfer in binary systems that allows a better resolution of the flow of matter between main-sequence stars. Our approach consists of modeling only the outermost layers of the stars using appropriate boundary conditions and ghost particles. We arbitrarily set the radius of the boundary and find that our boundary treatment behaves physically and conserves energy well. In particular, when used with our binary relaxation procedure, our treatment of boundary conditions is also shown to evolve circular binaries properly for many orbits. The results of our first simulation of mass transfer are also discussed and used to assess the strengths and limitations of our method. We conclude that it is well suited for the modeling of interacting binary stars. The method presented here represents a convenient alternative to previous hydrodynamical techniques aimed at modeling mass transfer in binary systems since it can be used to model both the donor and the accretor while maintaining the density profiles taken from realistic stellar models.

description: We present a study of $τ^{+}τ^{-}$ lepton pair production in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 5.5 TeV. The larger $τ^{\pm}$ mass ($\sim$ 1.77 GeV) compared to $e^{\pm}$ and $μ^{\pm}$ leads to considerably small hadronic contribution to the $τ^{+}τ^{-}$ pair invariant mass ($M$) distribution relative to the production from thermal partonic sources. The quark-anti-quark annihilation processes via intermediary virtual photon, Z and Higgs bosons have been considered for the production of $ τ^{+}τ^{-}$. We observe that the contribution from Drell-Yan process dominates over thermal yield for $τ^{+}τ^{-}$ pair mass from 4 to 20 GeV at the LHC energy. We also present the ratio of $τ$ lepton pair yields for nucleus-nucleus collisions relative to yields from p+p collisions scaled by number of binary collisions at LHC energies as a function $τ$ pair mass. The ratio is found to be significantly above unity for the mass range 4 to 6 GeV. This indicates the possibility of detecting $τ^{+}τ^{-}$ pair from quark gluon plasma (QGP) in the mass window $4\leq M$(GeV)$\leq 6$.

The countries in the scope of the deliverable are Denmark, Estonia, Finland, Norway, Latvia, Lithuania, and Sweden.
 Regarding policy implemented incentives for FAIR, the countries have taken different approaches. Policy implemented incentives are either in the form of national policies or law. Policies may be authored by different organisations, both organisations with national mandates, such as funders, and organisations with a subnational mandate, such as Higher Education Institutions (HEI:s). This also illuminates that different stakeholders are involved, ranging from ministries, and funders to HEI:s and libraries. Policies for (OS) training/training for making data FAIR, or policies that involve OS training, are available in some countries. In countries where neither policies nor training is available, there is awareness of the importance of policies for OS training/training for making data FAIR, which is reflected in some draft policies. OS training is provided by HEI:s in a majority of countries inventoried. A difference between the countries inventoried is that in some countries policy is set at a national level, in others, policies are set in addition to, or only at the subnational level. Most countries inventoried do not have policies in place for making other research objects FAIR. A conclusion, as has also been highlighted by other reports1, is that making other research objects FAIR is an area in need of focus in order to ensure transparency, reproducibility, and reusability of research. One country inventoried has a policy that mentions facilitation of cross-border research in the sense that national e-infrastructure is promoted to international users. The remainder of the inventoried countries have national policies, regarding access to resources, which focuses on researchers with national affiliation access to services. A conclusion is that in the Nordic and Baltic region, the facilitation of cross-border research is not a focus in policies, but policies rather have a national scope.

description: We evaluate the orbital evolution and several plausible origins scenarios for the mutually inclined orbits of Upsilon Andromedae c and d. These two planets have orbital elements that oscillate with large amplitudes and lie close to the stability boundary. This configuration, and in particular the observed mutual inclination, demands an explanation. The planetary system may be influenced by a nearby low-mass star, Upsilon And B, which could perturb the planetary orbits, but we find it cannot modify two coplanar orbits into the observed mutual inclination of ~30 deg. However, it could incite ejections or collisions between planetary companions that subsequently raise the mutual inclination to >30 deg. Our simulated systems with large mutual inclinations tend to be further from the stability boundary than Upsilon And, but we are able to produce similar systems. We conclude that scattering is a plausible mechanism to explain the observed orbits of Upsilon And c and d, but we cannot determine whether the scattering was caused by instabilities among the planets themselves or by perturbations from Upsilon And B. We also develop a procedure to quantitatively compare numerous properties of the observed system to our numerical models. Although we only implement this procedure to Upsilon And, it may be applied to any exoplanetary system.

description: We report on multi-band photometric and polarimetric observations of the blazars AO 0235+164 and PKS 1510-089. These two blazars were active in 2008 and 2009, respectively. In these active states, prominent short flares were observed in both objects, having amplitudes of >1 mag within 10 d. The $V-J$ color became bluer when the objects were brighter in these flares. On the other hand, the color of PKS 1510-089 exhibited a trend that it became redder when it was brighter, except for its prominent flare. This redder-when-brighter trend can be explained by the strong contribution of thermal emission from an accretion disk. The polarization degree increased at the flares, and reached >25 % at the maxima. We compare these flares in AO 0235+164 and PKS 1510-089 with other short flares which were detected by our monitoring of 41 blazars. Those two flares had one of the largest variation amplitudes in both flux and polarization degree. Furthermore, we found a significant positive correlation between the amplitudes of the flux and polarization degree in the short flares. It indicates that the short flares originate from the region where the magnetic field is aligned.

Analyse und Optimierung urbaner Energiesysteme - Entwicklung und Anwendung eines übertragbaren Modellierungswerkzeugs zur nachhaltigen Systemgestaltung

description: Viele Städte und Gemeinden sind sich ihrer Bedeutung für das Gelingen der Energiewende bewusst und verfolgen eigene Nachhaltigkeitsziele. Insbesondere in kleineren Gemeinden fehlt es jedoch häufig am nötigen Fachwissen, um bspw. die lokalen Emissionsminderungspotenziale quantifizieren und geeignete Maßnahmenkombinationen zur Erreichung dieser Ziele identifizieren zu können.
Daher wurde im Rahmen dieser Arbeit das RE³ASON (Renewable Energies and Energy Efficiency Analysis and System OptimizatioN) Modell entwickelt, mit dem für diese Gemeinden automatisierte Analysen, z. B. zur Bestimmung der Energienachfrage und der Potenziale für erneuerbare Energien, durchgeführt werden können. Bei der anschließenden Optimierung des jeweiligen Energiesystems können verschiedene Ziele verfolgt werden – bspw. die Minimierung der diskontierten Systemausgaben unter der Vorgabe zusätzlicher Emissionsminderungsziele. Die Optimierung umfasst dabei sowohl die Investitions- als auch die Einsatzplanung für Energieumwandlungstechnologien auf der Angebots- und Nachfrageseite.
Bei der Implementierung dieses Modells kommen verschiedene Methoden, u. a. aus den Bereichen der Geoinformatik, der Strahlungssimulation, der Betriebswirtschaftslehre, des maschinellen Lernens und der gemischt-ganzzahligen linearen Optimierung zum Einsatz. Ein inhaltlicher Schwerpunkt der Arbeit bildet die Bestimmung der Kosten und Potenziale für die Erzeugung von Strom und Wärme durch Photovoltaik-, Windkraft- und Biomasseanlagen. Besonderer Wert wurde auf die Übertragbarkeit der entwickelten Methoden gelegt, damit diese von möglichst vielen Städten und Gemeinden genutzt werden können. Hierfür wurden diverse öffentlich verfügbare und frei zugängliche Datenquellen genutzt und miteinander kombiniert, um die benötigten Eingangsdaten für die Analyse des städtischen Energiesystems zu generieren.
Die Anwendung des Modells im Rahmen mehrerer deutscher und internationaler Fallstudien zeigt unter anderem, dass insb. in kleineren Gemeinden bedeutende Potenziale zur Deckung des Energiebedarfs auf Basis erneuerbarer Energien bestehen. Weiterhin zeigt sich, dass die Umgestaltung des städtischen Energiesystems auf die Nutzung lokaler und nachhaltiger Energieressourcen auch aus Sicht der Gemeindevertreter die zu bevorzugende Alternative darstellen kann. Aus diesen Ergebnissen lassen sich schließlich Handlungsempfehlungen für städtische Entscheidungsträger ableiten. Kritisch anzumerken ist, dass die Modellergebnisse aufgrund der gewählten Systemgrenze keine nationalen energiewirtschaftlichen Schlussfolgerungen zulassen.

description: NH3 and CH3OH are key molecules in astrochemical networks leading to the formation of more complex N- and O-bearing molecules, such as CH3CN and HCOOCH3. Despite a number of recent studies, little is known about their abundances in the solid state. (...) In this work, we investigate the ~ 8-10 micron region in the Spitzer IRS (InfraRed Spectrograph) spectra of 41 low-mass young stellar objects (YSOs). These data are part of a survey of interstellar ices in a sample of low-mass YSOs studied in earlier papers in this series. We used both an empirical and a local continuum method to correct for the contribution from the 10 micron silicate absorption in the recorded spectra. In addition, we conducted a systematic laboratory study of NH3- and CH3OH-containing ices to help interpret the astronomical spectra. We clearly detect a feature at ~9 micron in 24 low-mass YSOs. Within the uncertainty in continuum determination, we identify this feature with the NH3 nu_2 umbrella mode, and derive abundances with respect to water between ~2 and 15%. Simultaneously, we also revisited the case of CH3OH ice by studying the nu_4 C-O stretch mode of this molecule at ~9.7 micron in 16 objects, yielding abundances consistent with those derived by Boogert et al. 2008 (hereafter paper I) based on a simultaneous 9.75 and 3.53 micron data analysis. Our study indicates that NH3 is present primarily in H2O-rich ices, but that in some cases, such ices are insufficient to explain the observed narrow FWHM. The laboratory data point to CH3OH being in an almost pure methanol ice, or mixed mainly with CO or CO2, consistent with its formation through hydrogenation on grains. Finally, we use our derived NH3 abundances in combination with previously published abundances of other solid N-bearing species to find that up to 10-20 % of nitrogen is locked up in known ices.
