description: The concept of Lorentz force can provide a propellantless electrostatic propulsion, through the interaction between an electrostatically charged satellite and the Earth\'s magnetic field to provide a useful thrust, which can be used for control both orbital and attitude motion. This idea needs to install an ion collector on the satellite to increase the level of charging as artificial charging. In this work the Lorentz force has been developed for two terms, a) first term, which was experienced with the magnetic field in the case of absolute charging of the spacecraft; b) the second term, which was experienced with the electric field in the case of differential charging of the spacecraft. We developed a mathematical model of fuel-optimal satellite formation keeping using a low thrust propulsion system using Electrostatic forces The linear time-varying relative dynamics which describe the relative motion in the presence of second zonal harmonic perturbation and total Lorentz force have developed. The proposed controller includes a feedback control using a real-time fuel-optimal control approach are considered. Application of a Legendre pseudospectral method is presented using quadratic programming for the fuel-optimal control problem. Feedforward control (iterative learning control) is used to improve formation keeping accuracy by eliminating the effects of periodic perturbations due to second zonal harmonics. The simulation results confirm the capability of using Lorentz force to provide an optimal propellantless to control the of formation keeping.

description: Francisella tularensis is a gram negative facultative intracellular pathogen which is a class A biothreat according to the CDC. This bacteria codes for two chitinases (ChiA and ChiB) and one chitin binding protein (CbpA). Chitin is the most abundant oligosaccharide in marine environments and in the exoskeleton of many insects. In order to digest this material, microorganisms produce chitinases capable of cleaving this polymer. The chitinases in Francisella novicida have previously been found by our lab to negatively regulate the bacterial biofilm, most likely cleaving the extracellular polysaccharide substance (EPS) with β-1,4 glycosidic linkages. These enzymes may enable the organism to use the resulting cleaved polymers as carbon and nitrogen sources for growth. Although Francisella encodes for several polysaccharide synthases, it has not been found to produce chitin. Therefore, we hypothesized that the chitinase-enzyme substrate that is self-produced in the F. novicida EPS and biofilm must be some other molecule also containing β-1,4 glycosidic linkages. The biochemical characterization of ChiB activity on various substrates will be evaluated and the role of the substrate in the biofilm will be examined. Based on the preliminary data from the van Hoek lab and other labs, we think that chitinases play important roles both in Francisella ecological persistence and macrophage mediated growth during Francisella infection. Identifying and characterizing the substrate for these chitinases will generate information on how Francisella uses them to persist in the environment and replicate in human macrophages.

description: The conceptual and preliminary design phases of aircraft projects encompass key initial tasks in configuration selection, sizing and optimisation. Relevant current trends include the use of higher fidelity tools, the study of unconventional configurations and the development of design methodologies for Remotely Piloted Aircraft Systems (RPAS). Some of these features are being incorporated in computerised design environments which are becoming increasingly widespread. The objective of this investigation is to conduct a review of current capabilities of these environments to assess the key capabilities, considering the particularities of these aircraft, towards elaborating a new design environment focused on remotely piloted platforms.

description: Der bei Scharnhausen gelegene Vulkanschlot ist der nördlichste des mittelmiozänen Urach-Kirchheimer Vulkanfelds. Seine von Wilhelm Branco im Jahr 1892 beschriebene Tuffbrekzie mit Gesteinskomponenten des beim Ausbruch durchschlagenen mesozoischen Deckgebirges liefert wichtige Indizien für die Rekonstruktion der regionalen Landschaftsgeschichte. Von besonderer Bedeutung sind die vielzitierten Weißjurakalke in dieser Schlotfüllung. Eine Nachuntersuchung des Originalmaterials zeigt jedoch, dass in der Scharnhäuser Tuffbrekzie gar keine Weißjurakalke enthalten sind und Branco diverse Kalksteine aus dem Schwarzjura damit verwechselt hat. Als Konsequenz dieses Befunds und weiterer Überlegungen wird angenommen, dass der Albtrauf im Abschnitt des heutigen Fildergrabens zur Zeit des miozänen Albvulkanismus knapp südlich des heutigen Neckartals gelegen haben dürfte.

Subjects: subject: Co-location

description: Co-location involves the intentional siting together of public facilities. Co-location of public facilities is becoming an increasingly common practice, particularly for its perceived benefits of resource savings, increased efficiency and synergy of services, and enhanced sense of community. Such advantages may be especially critical in a location undergoing rapid growth. The ability to plan and manage the process of co-locating public facilities can be very important to the successful, efficient growth of a community. However, there can be significant challenges. Deliberate planning can be problematic in an environment of rapid growth. Co-location may instead be left to opportunity, which does little to maximize overall resource savings or to establish a coherent, long-term policy of co-location. Modeling can also be problematic in a rapidly changing environment. In general, modeling has proven to be limited in terms of serving as a predictive siting tool for public facilities under real-world conditions. There are no one-size-fits-all models for siting facilities, let alone for co-locating them, which is a far more complex endeavor. Thus, a more sustainable approach might be to develop a decision support tool. This research develops a Spatial Decision Support System (SDSS) to co-locate public facilities in Loudoun County, a rapidly growing county in northern Virginia. The goal of the project is to determine if employing a SDSS based on CommunityViz in ArcGIS 9.2 facilitates successful co-location of public facilities in a dynamic decision-making environment.

description: We identify three-dimensional higher-order superconductors characterized by the coexistence of one-dimensional Majorana hinge states and gapless surface sates. We show how such superconductors can be obtained starting from the model of a spinful quadrupolar semimetal with two orbitals and adding an s-wave superconducting pairing term. By considering all the possible s-wave pairings satisfying Fermi-Dirac statistics we obtain six different superconducting models. We find that for two of these models a flat-band of hinge Majorana states coexist with surface states, and that these models have a non-vanishing quadrupole-like topological invariant. Two of the other models, in the presence of a Zeeman term, exhibit helical and dispersive hinge states localized only at two of the four hinges. We find that these states are protected by combinations of rotation and mirror symmetries, and that the pair of corners exhibiting hinge states switches upon changing the sign of the Zeeman term. Furthermore, we show that these states can be localized to a single hinge with suitable perturbations. The remaining two models retain gapless bulk and surface states that spectroscopically obscure any possible hinge states.

description: In recent investigations at DLR Lampoldshausen a highly active catalytically promoted ionic liquid fuel with hydrogen peroxide was found. This fuel is based on an ionic liquid and a dissolved metal salt as catalytic promoter. But due to high viscosity of this fuel and bad mixing behaviour between hydrogen peroxide and fuel reliable ignition was not achieved. This investigation introduced different amounts of an organic solvent to the fuel and drop test were conducted to evaluate hypergolic performance. Repeatable ignition was achieved and the ignition delay times were around 28 ms.

description: We study thermal relaxation in ordered arrays of coupled nonlinear elements with external driving. We find, that our model exhibits dynamic self-organization manifested in a universal stretched-exponential form of relaxation. We identify two types of self-organization, cooperative and anti-cooperative, which lead to fast and slow relaxation, respectively. We give a qualitative explanation for the behavior of the stretched exponent in different parameter ranges. We emphasize that this is a system exhibiting stretched-exponential relaxation without explicit disorder or frustration.

description: This thesis looks at water privatization initiatives, and particularly concessions, in Latin America from the perspective of structural violence. Ten cases are evaluated and two (Cartagena, Colombia and Tucuman, Argentina) are looked at in greater detail. The goal of this thesis is to gain a different perspective and definition on how ‘success’ is defined in water privatization initiatives. My findings guide me to a new definition: ‘Success’ in the status quo fundamentally lacks public participation and consultation, possesses inappropriate subsidies and insufficient efforts to connect illegal settlements, does not guarantee access to water and fails to make adequate conservation efforts that are not financially viable.

We advocate satellite-based experiments to improve the sensitivity.

description: Several recent proposals to embed inflation into high-energy physics rely on inflationary dynamics characterized by a strongly non-geodesic motion in negatively curved field space. This naturally leads to a transient instability of perturbations on sub-Hubble scales, and to their exponential amplification. Supported by first-principle numerical computations, and by the analytical insight provided by the effective field theory of inflation, we show that the bispectrum is enhanced in flattened configurations, and we argue that an analogous result holds for all higher-order correlation functions. These ``hyper non-Gaussianities'' thus provide powerful model-independent constraints on non-standard inflationary attractors motivated by the search for ultraviolet completions of inflation.

description: Carbon fibre reinforced polymers (CFRPs) present an outstanding performance in terms of mechanical performance and weight. However, when reaching their mechanical limits, they are related to delamination and catastrophic failure. This study proposes a new structure of CFRPS laminates to enhance their toughness and modify their typical failure mode. An industrial manufacturing method is used to produce the proposed new systems and tensile tests are performed to them to demonstrate a \"pseudo-ductile\" behaviour.

description: In Thomas Sargent’s 1982 journal the Ends of Four Big Inflations, he conducted several case studies on historic hyperinflations occurring in the early to mid-1900s. This thesis draws large amounts of inspiration from this and Sargent’s other work by utilizing a case study approach to analyze four more hyperinflationary crises occurring in the modern era (1990s-present). For each of these cases, this thesis observes the instrumental role fiscal-monetary elements such as fiscal responsibility, central bank independence, and credibility play in both the formation and conclusion of these modern crises. While each of these crises were preceded by differing domestic conditions, actions conducted by each nation’s fiscal-monetary regime would result in the abandonment of these key elements ultimately triggering each case of hyperinflation. This thesis contains two chapters. Chapter one briefly introduces the three main fiscal-monetary elements by describing the various implications resulting from either the retainment or abandonment of them. Chapter two presents the formation and conclusion of the hyperinflation crises of Zimbabwe, Yugoslavia, Armenia, and Venezuela with an exploration of the actions conducted by the fiscal-monetary regime of each country. Venezuela’s case does not include details on the conclusion of the hyperinflation due the crisis being ongoing. This case instead demonstrates how the non-reestablishment of key fiscal-monetary elements contributes to the continuation of the crisis.

description: Entanglement entropy is an important quantity in field theory, but its definition poses some challenges. The naive definition involves an extension of quantum field theory in which one assigns Hilbert spaces to spatial sub-regions. For two-dimensional topological quantum field theory we show that the appropriate extension is the open-closed topological quantum field theory of Moore and Segal. With the addition of one additional axiom characterizing the `entanglement brane' we show how entanglement calculations can be cast in this framework. We use this formalism to calculate modular Hamiltonians, entanglement entropy and negativity in two-dimensional Yang-Mills theory and relate these to singularities in the modular flow. As a byproduct we find that the negativity distinguishes between the `log dim R' edge term and the `Shannon' edge term. We comment on the possible application to understanding the Bekenstein-Hawking entropy in two-dimensional gravity.

Faziesentwicklung des Oberen Hauptquaders und der Oberen Terebratelbank (Oberer Muschelkalk, Trias, Südwestdeutschland)

description: Der Obere Hauptquader (Quaderkalk-Formation, Oberer Muschelkalk, Mittlere Trias) in Südwestdeutschland repräsentiert einen fossilen Karbonat-„Sandkörper“ (Shoal), der auf einer epikontinentalen und flach einfallenden Karbonatrampe nordwestlich des Vindelizisch-Böhmischen Massivs abgelagert wurde. Er ist der größte und mächtigste von vier geologischen Körpern, welche die Quaderkalk-Formation bilden und lässt sich mit küstennahen Karbonat-Sandkörpern aus dem heutigen östlichen Arabischen/Persischen Golf vergleichen. Überlagert wird dieser Körper von der Oberen Terebratelbank, die einen wichtigen Leithorizont im Oberen Muschelkalk darstellt. Die vorliegende Publikation untersucht im Zuge einer hochauflösenden sedimentologischen Studie die räumliche Faziesverteilung und Paläoströmungen des Oberen Hauptquaders und der Oberen Terebratelbank. Ziel dieser Studie ist eine detaillierte Rekonstruktion des Ablagerungsraumes sowie des Paläo-Strömungssystems. Zu diesem Zweck wurden von 71 Steinbrüchen und Bohrkernen sedimentologische Profile aufgenommen und eine Faziesanalyse durchgeführt, die mit mehr als 400 Dünnschliffen optimiert wurde. Des Weiteren wurden Steinbruch-Wände kartiert, 2D-Korrelationen und Fazieskarten erstellt und zwei Ablagerungsmodelle entwickelt. Anstelle eines homogenen und kontinuierlichen Oberen Hauptquaders deuten die Ergebnisse auf ein Mosaik aus mehreren kleineren Karbonat-Sandkörpern hin. Einzelne Sandkörper zeigen eine heterogene Faziesverteilung, die auf Eventablagerungen und kleinskalige Meeresspiegelschwankungen zurückzuführen ist. Die Faziesverteilung der Oberen Terebratelbank zeigt ebenfalls ein heterogenes Muster, das von Sturm-bedingten Ablagerungen über Bivalven- und Brachiopoden-Bänke bis hin zu Biohermen reicht. Die Rekonstruktion des Paläo-Strömungssystems impliziert ein komplexes Zusammenspiel zwischen täglichen Wind-induzierten Strömungen, Stürmen und Tiden-Strömungen.

Topological transitions and freezing in XY models and Coulomb gases with quenched disorder: renormalization via traveling waves

description: We study the two dimensional XY model with quenched random phases and its Coulomb gas formulation. A novel renormalization group (RG) method is developed which allows to study perturbatively the glassy low temperature XY phase and the transition at which frozen topological defects (vortices) proliferate. This RG approach is constructed both from the replicated Coulomb gas and, equivalently without the use of replicas, using the probability distribution of the local disorder (random defect core energy). By taking into account the fusion of environments (i.e charge fusion in the replicated Coulomb gas) this distribution is shown to obey a Kolmogorov's type (KPP) non linear RG equation which admits travelling wave solutions and exhibits a freezing phenomenon analogous to glassy freezing in Derrida's random energy models. The resulting physical picture is that the distribution of local disorder becomes broad below a freezing temperature and that the transition is controlled by rare favorable regions for the defects, the density of which can be used as the new perturbative parameter. The determination of marginal directions at the disorder induced transition is shown to be related to the well studied front velocity selection problem in the KPP equation and the universality of the novel critical behaviour obtained here to the known universality of the corrections to the front velocity. Applications to other two dimensional problems are mentionned at the end.

description: We obtain a full characterization of Einstein-Maxwell $p$-form solutions $(\boldsymbol{g},\boldsymbol{F})$ in $D$-dimensions for which all higher-order corrections vanish identically. These thus simultaneously solve a large class of Lagrangian theories including both modified gravities and (possibly non-minimally coupled) modified electrodynamics. Specifically, both $\boldsymbol{g}$ and $\boldsymbol{F}$ are fields with vanishing scalar invariants and further satisfy two simple tensorial conditions. They describe a family of gravitational and electromagnetic plane-fronted waves of the Kundt class and of Weyl type III (or more special). The local form of $(\boldsymbol{g},\boldsymbol{F})$ and a few examples are also provided.

description: The nuclear level density and $γ$-decay strength of $^{192}$Os have been extracted using particle-$γ$ coincidence data from the $^{192}$Os($α,α^\primeγ$)$^{192}$Os reaction by means of the Oslo method. The level density is found to be a rather smooth function of excitation energy, approximately following the constant temperature model. The $γ$-decay strength is compared to photoneutron cross-section data above the neutron separation energy, and to $E1$ and $M1$ strengths for nuclei in this mass region derived from primary transitions following neutron capture. Our results are in good agreement with these previous data and draw a consistent picture of the $γ$-strength function in the range $E_γ\approx 1.5-6 $ MeV. Using the measured nuclear level density and $γ$-decay strength as input to the nuclear-reaction code TALYS, we provide the first experimentally constrained Maxwellian-averaged cross section (MACS) for the $^{191}$Os($n,γ$)$^{192}$Os reaction relevant to $s$-process nucleosynthesis. The systematic uncertainties introduced by the normalization procedure of the level density and $γ$-strength function were investigated and propagated to the calculated Maxwellian-averaged cross section. The obtained result of the Maxwellian-averaged cross section at $k_BT=30$ keV, $\langle σ\rangle_{n,γ}=1134\pm 375$ mb, is in very good agreement with the theoretical estimate provided by the KADoNiS project, giving experimental support to the adopted KADoNiS value. Good agreement is also found with MACS values obtained from other libraries, such as TENDL-2017, ENDF/B-VII.0, and JEFF.

description: Crystallisation of bioactive glasses has been claimed to negatively affect the ion release from bioactive glasses. Here, we compare ion release and mineralisation in Tris–HCl buffer solution for a series of glass–ceramics and their parent glasses in the system SiO2–CaO–P2O5–CaF2. Time-resolved X-ray diffraction analysis of glass–ceramic degradation, including quantification of crystal fractions by full pattern refinement, show that the glass–ceramics precipitated apatite faster than the corresponding glasses, in agreement with faster ion release from the glass–ceramics. Imaging by transmission electron microscopy and X-ray nano-computed tomography suggest that this accelerated degradation may be caused by the presence of nano-sized channels along the internal crystal/glassy matrix interfaces. In addition, the presence of crystalline fluorapatite in the glass–ceramics facilitated apatite nucleation and crystallisation during immersion. These results suggest that the popular view of bioactive glass crystallisation being a disadvantage for degradation, apatite formation and, subsequently, bioactivity may depend on the actual system study and, thus, has to be reconsidered.
Die Bedeutung der Mixotrophie in der Pflanzenernährung mit besonderer Berücksichtigung der Ackerkratzdistel

description: Mixotrophe Pflanzen besitzen die Fähigkeit, neben der CO2-Assimilierung im Rahmen der Photosynthese auch organische Moleküle als Kohlenstoffquelle aufzunehmen. Mixotrophie kann in Form von Parasitismus, Karnivorie, Probiose, Symbiose oder Saprotrophie auftreten. Beispielsweise leben Misteln und eine Reihe von Scrophulariaceen als Halbparasiten. Orchideen wiederum nutzen unterschiedliche Probiosen und Symbiosen, wohingegen sich die Ackerkratzdistel (Cirsium arvense) durch einen (partiell) saprotrophen Lebensstil zur unerwünschten Begleitpflanze entwickeln kann. Die Formen ihres Auftretens lassen auf unterschiedliche Ernährungsmuster schließen. Dieser Beitrag diskutiert aktuelle Forschungsergebnisse und gibt auf dieser Grundlage Hinweise auf die praktische Regulierung der Ausbreitung der Ackerkratzdistel. Dabei reicht es im Wesentlichen aus, die probiotischen Eigenschaften des Bodens zu regulieren.

Deuteron Structure Functions in the Context of Few-Body Physics

description: Few-body systems offer a unique challenge to those interested in deep inelastic scattering. Using the deuteron as the simplest and most easily solvable nuclear system we review the main physics issues in the valence and sea quark regimes. For the former the key issue is the understanding of Fermi motion and binding corrections, and our ability to extract the ratio F_2n/F_2p as x -> 1. The most recent analysis of deuteron data for F_2n/F_2p is consistent with perturbative QCD, but inconsistent with the assumptions common to all standard parton distribution fits. This should be taken into account in calculating event rates at HERA --- especially at large x and Q^2. The extraction of g_1n also presents an opportunity to refine the description of nuclear effects in spin-dependent structure functions. In the region of small x one must correct for shadowing and meson exchange current effects in order to explore the flavor structure of sea, which is, in turn, deeply related to the chiral structure of the nucleon.

Prospects for detecting the astrometric signature of Barnard's Star b

description: A low-amplitude periodic signal in the radial velocity (RV) time series of Barnard's Star was recently attributed to a planetary companion with a minimum mass of ${\sim}$3.2 $M_\oplus$ at an orbital period of $\sim$233 days. The relatively long orbital period and the proximity of Barnard's Star to the Sun raises the question whether the true mass of the planet can be constrained by accurate astrometric measurements. By combining the assumption of an isotropic probability distribution of the orbital orientation with the RV-analysis results, we calculated the probability density function of the astrometric signature of the planet. In addition, we reviewed the astrometric capabilities and limitations of current and upcoming astrometric instruments. We conclude that Gaia and the Hubble Space Telescope (HST) are currently the best-suited instruments to perform the astrometric follow-up observations. Taking the optimistic estimate of their single-epoch accuracy to be $\sim$30 $μ$as, we find a probability of $\sim$10% to detect the astrometric signature of Barnard's Star b with $\sim$50 individual-epoch observations. In case of no detection, the implied mass upper limit would be $\sim$8 $M_\oplus$, which would place the planet in the super-Earth mass range. In the next decade, observations with the Wide-Field Infrared Space Telescope (WFIRST) may increase the prospects of measuring the true mass of the planet to $\sim$99%.

description: Proper application of a fertilizer requires precise knowledge of its nutrient composition. In the case of liquid organic manures (LOM), this information is often lacking due to heterogeneous nature of these fertilizers. Published “book values” of nutrient contents present the average from a wide range of possible nutrient characteristics, but usually differ considerably from the concentration in a particular manure. Thus, chemical analyses are recommended before applying the specific LOM. Unfortunately, this is usually too costly and time-intensive in practical farming. On-farm analysis by optical spectrometry in the visible and near-infrared (Vis-NIR) range is considered as an efficient alternative. However, calibration of Vis-NIR spectrometry for LOM is challenging as shown in many studies. One reason is LOMs’ tendency to rapidly segregate into a fuzzy continuum with liquid and solid properties. By separating LOM into well-defined liquid and solid phases and measuring them separately, calibration of Vis-NIR spectrometry might be improved. In this study, the effects of four sample pre-treatment techniques on the prediction accuracy of macronutrients (N, P, K, Mg, Ca, S), micronutrients (B, Mn, Fe, Cu, Zn), dry matter and pH of LOM using visible and near infrared spectrometry were comprehensively investigated. The concentrations were referred either to wet basis or to dry matter basis. For the study, a total of 163 samples, separated in two similar LOM sets (pig, cattle, digestates), were either dried, filtered, or centrifuged and always compared to non-treated samples. The experiments demonstrate that in comparison to raw samples (Ø r2 = 0.85) neither filtering (Ø r2 = 0.76 for filtrates and Ø r2 = 0.71 for filter residues), centrifugation (Ø r2 = 0.59 for supernatants and Ø r2 = 0.79 for pellets), nor drying (Ø r2 = 0.74) revealed to be a helpful preparation step significantly improving prediction results, independent from referring to wet or dry basis concentrations.

description: We present a formalism to study screening mechanisms in modified theories of gravity via perturbative methods in different cosmological scenarios. We consider Einstein frame posed theories that are recast as Jordan frame theories, where a known formalism is employed, though the resulting non-linearities of the Klein-Gordon equation acquire an explicit coupling between matter and the scalar field, which is not present in Jordan frame theories. The obtained growth functions are then separated in screening and non-screened contributions to facilitate its analysis. This allows us to compare several theoretical models and to recognize patterns which can be used to differentiate models and their screening mechanisms. In particular, we find anti-screening features in the Symmetron model. In opposition, chameleon type theories, both in the Jordan and in the Einstein frame, always present a screening behaviour. Up to third order in perturbation, we find no anti-screening behaviour in theories with a Vainshtein mechanism, such as the DGP and the cubic Galileon.

description: In the scope of the ExoMars 2020 mission, this paper addresses the formal analysis and verification of the cruise GNC with as main focus the certification of the control loops in terms of stability and robustness. In particular, it is shown how the main cruise GNC control loop can be modelled as a socalled linear fractional transformation (LFT) model, while explicitly including parametric and dynamic uncertainties such as MCI parameters, un-modelled dynamics, delay, estimation errors, etc. Subsequently, it will be demonstrated by means of the -tools that the structured singular value (SSV) or -theory can be adopted for the systematic verification and certification of robustness of the uncertain system.
