description: The principles of the Industry 4.0 are guiding manufacturing companies towards more automated and computerized factories. Such principles are also applied in shipbuilding, which usually involves numerous complex processes whose automation will improve its efficiency and performance. Navantia, a company that has been building ships for 300 years, is modernizing its shipyards according to the Industry 4.0 principles with the help of the latest technologies. Augmented Reality (AR), which when utilized in an industrial environment is called Industrial AR (IAR), is one of such technologies, since it can be applied in numerous situations in order to provide useful and attractive interfaces that allow shipyard operators to obtain information on their tasks and to interact with certain elements that surround them. This article first reviews the state of the art on IAR applications for shipbuilding and smart manufacturing. Then, the most relevant IAR hardware and software tools are detailed, as well as the main use cases for the application of IAR in a shipyard. Next, it is described Navantia's IAR system, which is based on a fog-computing architecture. Such a system is evaluated when making use of three IAR devices (a smartphone, a tablet and a pair of smart glasses), two AR SDKs (ARToolKit and Vuforia) and multiple IAR markers, with the objective of determining their performance in a shipyard workshop and inside a ship under construction. The results obtained show remarkable performance differences among the different IAR tools and the impact of factors like lighting, pointing out the best combinations of markers, hardware and software to be used depending on the characteristics of the shipyard scenario.

description: We show that the number of supersymmetries of IIB black hole horizons is N=2 N_- + 2 index(D_λ), where index(D_λ) is the index of the Dirac operator twisted with the line bundle λ^{1/2} of IIB scalars, and N_- is the dimension of the kernel of a horizon Dirac operator which depends on IIB fluxes. Therefore, all IIB horizons preserve an even number of supersymmetries. In addition if the horizons have non-trivial fluxes and N_- is nonzero, then index(D_λ) is non-negative, and the horizons admit an sl(2,R) symmetry subalgebra. This provides evidence that all such horizons have an AdS/CFT dual. Furthermore if the orbits of sl(2,R) are two-dimensional, the IIB horizons are warped products AdS_2 X S.

description: This habilitation thesis is focusing on improving site- and year-specific modelling of net N mineralization in agricultural soils of Northern Germany for online N fertilizer recommendation purposes. The overall goal of the studies were to experimentally parameterize and evaluate a net N mineralization model allowing site-specific online parameterization. Futhermore, substances and processes possibly involved in unusually low net N mineralization in soils with specific former land uses, that are relatively rich in total organic C and N, were elucidated in order to adequately account for it in simulations. The synopsis is dedicated to merge the results from the six included papers plus a description of the achieved model applications, potential model limitations as well as the current working hypothesis on the mode of action of the inhibiting soil organic substances.

description: We consider the free boundary problem for the plasma-vacuum interface in ideal compressible magnetohydrodynamics (MHD). In the plasma region the flow is governed by the usual compressible MHD equations, while in the vacuum region we consider the pre-Maxwell dynamics for the magnetic field. At the free-interface, driven by the plasma velocity, the total pressure is continuous and the magnetic field on both sides is tangent to the boundary. The plasma-vacuum system is not isolated from the outside world, because of a given surface current on the fixed boundary that forces oscillations. Under a suitable stability condition satisfied at each point of the initial interface, stating that the magnetic fields on either side of the interface are not collinear, we show the existence and uniqueness of the solution to the nonlinear plasma-vacuum interface problem in suitable anisotropic Sobolev spaces. The proof is based on the results proved in the companion paper arXiv:1112.3101, about the well-posedness of the homogeneous linearized problem and the proof of a basic a priori energy estimate. The proof of the resolution of the nonlinear problem given in the present paper follows from the analysis of the elliptic system for the vacuum magnetic field, a suitable tame estimate in Sobolev spaces for the full linearized equations, and a Nash-Moser iteration.

description: We employ an effective-field theory with correlations in order to study the phase diagram and ground-state magnetizations of a selectively diluted Ising antiferromagnet on triangular and honeycomb lattices. Dilution of different sublattices with generally unequal probabilities results in a rather intricate phase diagram in the sublattice dilution parameters space. In the case of the frustrated triangular lattice antiferromagnet the selective dilution affects the degree of frustration which can lead to some peculiar phenomena, such as reentrant behavior of long-range order or unsaturated sublattice magnetizations at zero temperature. The selectively diluted Ising antiferromagnet on the honeycomb lattice is obtained as a special case when one sublattice of the triangular lattice is completely removed by dilution.

description: Data from the Atacama Cosmology Telescope (ACT) and the South Pole Telescope (SPT), combined with the nine-year data release from the WMAP satellite, provide very precise measurements of the cosmic microwave background (CMB) angular anisotropies down to very small angular scales. Augmented with measurements from Baryonic Acoustic Oscillations surveys and determinations of the Hubble constant, we investigate whether there are indications for new physics beyond a Harrison-Zel'dovich model for primordial perturbations and the standard number of relativistic degrees of freedom at primordial recombination. All combinations of datasets point to physics beyond the minimal Harrison-Zel'dovich model in the form of either a scalar spectral index different from unity or additional relativistic degrees of freedom at recombination (e.g., additional light neutrinos). Beyond that, the extended datasets including either ACT or SPT provide very different indications: while the extended-ACT (eACT) dataset is perfectly consistent with the predictions of standard slow-roll inflation, the extended-SPT (eSPT) dataset prefers a non-power-law scalar spectral index with a very large variation with scale of the spectral index. Both eACT and eSPT favor additional light degrees of freedom. eACT is consistent with zero neutrino masses, while eSPT favors nonzero neutrino masses at more than 95% confidence.

description: Non-geometric frames in string theory are related to the geometric ones by certain local O(D,D) transformations, the so-called $β$-transforms. For each such transformation, we show that there exists both a natural field redefinition of the metric and the Kalb-Ramond two-form as well as an associated Lie algebroid. We furthermore prove that the all-order low-energy effective action of the superstring, written in terms of the redefined fields, can be expressed through differential-geometric objects of the corresponding Lie algebroid. Thus, the latter provides a natural framework for effective superstring actions in non-geometric frames. Relations of this new formalism to double field theory and to the description of non-geometric backgrounds such as T-folds are discussed as well.

description: Der Einsatz von natürlichen Gegenspielern hat sich in den vergangenen Jahrzehnten zu einem bedeutendem Instrument im biologischen und integriertem Pflanzenschutz entwickelt. Zur Anwendung kommen dabei im geschützten Anbau und im Freiland verschiedene Nutzorganismen (Pilze, Viren, Bakterien, Nematoden, Räuber, Parasitoide), die gezielt eingesetzt oder aber im Freiland im Rahmen des konservierenden biologischen Pflanzenschutzes gefördert werden können. Um die Effizienz und Wirksicherheit von natürlichen Gegenspielern zu verbessern, wurde in der Vergangenheit verstärkt der kombinierte Einsatz von natürlichen Gegenspielern diskutiert (Kapitel 01). Daraus ergibt sich ebenfalls die Notwendigkeit, die Betrachtung von einfachen Räuber-Beute Beziehungen auf Wechselwirkungen über mehrere trophische Ebenen auszuweiten. Diese Wechselwirkungen haben den Begriff „Intraguild Predation“ (IGP) geprägt und kennzeichnen die Fraßbeziehung innerhalb der Gilde von Antagonisten, die an einer gemeinsamen Ressource, d.h. Schädlingen/Herbivoren, fressen. Vor allem Untersuchungen zur Populationsdynamik von Herbivoren haben die generelle Bedeutung der IGP für natürliche Gegenspieler unterstrichen und dazu geführt die Bedeutung von trophischen Ebenen zu verallgemeinern. Im Kontext von trophischen Wechselwirkungen wird deshalb von omnivorer IGP gesprochen, wenn räuberische Organismen neben Herbivoren auch andere räuberische Organismen angreifen, bzw. von zufälliger IGP, wenn räuberische Organismen bei ihrem Nahrungserwerb andere natürliche Gegenspieler (z.B. endoparasitische Schlupfwespen) zufällig mitfressen. Je nach Antagonisten Gruppe können diese Wechselwirkungen entweder symmetrisch bzw. bidirektional (Räuber – Räuber – Interaktionen) oder aber asymmetrisch bzw. unidirektional (Räuber – Parasitoid – Interaktionen) ausgeprägt sein. Im Rahmen der Untersuchungen der Habilitationsschrift wurden multitrophe Wechselwirkungen bei natürlichen Gegenspielern untersucht um die Auswirkungen von IGP auf die Populationsentwicklung von Schadinsekten im Freiland bzw. Gewächshaus zu charakterisieren.

description: We present 2D magnetohydrodynamic simulations performed with the PLUTO code to model magnetized star-planet interactions. We study two simple scenarios of magnetized star-planet interactions: the unipolar and dipolar interactions. Despite the simplified hypotheses we consider in the model, the qualitative behavior of the interactions is very well recovered. These encouraging results promote further developments of the model to obtain predictions on the effect and the physical manifestation of magnetized star--close-in planet interactions.

We prove that each first-countable Abelian paratopological group is submetrizable. Moreover, we discuss developable paratopological groups and construct a non-metrizable, Moore paratopological group. Further, we prove that a regular, countable, locally $k_ω$-paratopological group is a discrete topological group or contains a closed copy of $S_ω$. Finally, we discuss some properties on non-H-closed paratopological groups, and show that Sorgenfrey line is not H-closed, which gives a negative answer to Arhangel'ski\vı\ and Tkachenko's question [Topological Groups and Related Structures, Atlantis Press and World Sci., 2008]. Some questions are posed.

description: Textures in images can often be well modeled using self-similar processes while they may at the same time display anisotropy. The present contribution thus aims at studying jointly selfsimilarity and anisotropy by focusing on a specific classical class of Gaussian anisotropic selfsimilar processes. It will first be shown that accurate joint estimates of the anisotropy and selfsimilarity parameters are performed by replacing the standard 2D-discrete wavelet transform by the hyperbolic wavelet transform, which permits the use of different dilation factors along the horizontal and vertical axis. Defining anisotropy requires a reference direction that needs not a priori match the horizontal and vertical axes according to which the images are digitized, this discrepancy defines a rotation angle. Second, we show that this rotation angle can be jointly estimated. Third, a non parametric bootstrap based procedure is described, that provides confidence interval in addition to the estimates themselves and enables to construct an isotropy test procedure, that can be applied to a single texture image. Fourth, the robustness and versatility of the proposed analysis is illustrated by being applied to a large variety of different isotropic and anisotropic self-similar fields. As an illustration, we show that a true anisotropy built-in self-similarity can be disentangled from an isotropic self-similarity to which an anisotropic trend has been superimposed.

The city gates and the bigger public buildings were arranged at about 45° relative to the cardinal directions. However, one of the temples features a remarkable deviation from this general orientation. The following analysis shows that both, the general orientation of the public buildings and the deviation of one of the temples are related to astronomical observations, particularly to the course of the sun, and maybe also to some special points of the course of the Venus.

description: Molecular clouds act as primary targets for cosmic-ray interactions and are expected to shine in gamma-rays as a by-product of these interactions. Indeed several detected gamma-ray sources both in HE and VHE gamma-rays (HE: 100 MeV < E < 100 GeV; VHE: E > 100 GeV) have been directly or indirectly associated with molecular clouds. Information on the local diffusion coefficient and the cosmic-ray population can be inferred from the observed gamma-ray signals. In this work we explore the capability of the forthcoming Cherenkov Telescope Array Observatory (CTA) to provide such measurements. We investigate the expected emission from clouds hosting an accelerator, surveying the parameter space for different modes of acceleration, age of the source, cloud density profile, and cosmic-ray diffusion coefficient. We present some of the most interesting cases for CTA regarding this science topic. The simulated gamma-ray fluxes depend strongly on the input parameters. In several cases, we find that it will be possible to constrain both the properties of the accelerator and the propagation mode of cosmic rays in the cloud from CTA data alone.

description: A space $X$ is said to be $π$-metrizable if it has a $σ$-discrete $π$-base. In this paper, we mainly give affirmative answers for two questions about $π$-metrizable spaces. The main results are that: (1) A space $X$ is $π$-metrizable if and only if $X$ has a $σ$-hereditarily closure-preserving $π$-base; (2) $X$ is $π$-metrizable if and only if $X$ is almost $σ$-paracompact and locally $π$-metrizable; (3) Open and closed maps preserve $π$-metrizability; (4) $π$-metrizability satisfies hereditarily closure-preserving regular closed sum theorems. Moreover, we define the notions of second-countable $π$-metrizable and strongly $π$-metrizable spaces, and study some related questions. Some questions about strongly $π$-metrizability are posed.

description: Amino acids are among the most versatile compounds in plants performing diverse functions within proteins as well as individually. The publications constituting this habilitation thesis focus on different aspects of amino acid catabolism. Not all of the biochemical pathways catalyzing degradation of the twenty proteinogenic amino acids in plants are known, and annotation of amino acid catabolic enzymes in databases and pathway maps is still insufficient for comprehensive evaluation of proteomics or transcriptomics datasets. Thus, a manually assembled pathway map covering 136 reactions involved in amino acid related pathways is presented and used for reevaluation of already published as well as interpretation of new omics datasets. This approach clearly defines gaps in the present knowledge and at the same time postulates candidate proteins for unknown reactions as a starting point for further investigation. In addition, it provides insight into the different metabolic functions of amino acid catabolism and their significance during abiotic and biotic stress response. A major topic of the work presented here is cysteine catabolism. Cysteine in addition to the amino group also contains a thiol moiety and therefore represents an intersection of carbon, nitrogen and sulfur metabolism. The degradation of cysteine via different enzymatic routes releases reduced sulfur in the form of sulfide or persulfide, which act as signaling molecules and can be further metabolized either by reincorporation into cysteine or by oxidation. This thesis describes a mitochondrial cysteine catabolic pathway that oxidizes the thiol group catalyzed by the sulfur dioxygenase ETHE1. In plants, this pathway is essential during early embryo development and also required for energy metabolism during low light availability. Mutations in the ETHE1 gene in humans cause the metabolic disease ethylmalonic encephalopathy, which is characterized by rapidly progressive encephalopathy, chronic diarrhea, and peripheral microangio¬pathy caused by accumulation of toxic sulfide levels. These symptoms can be relieved by combined treatment with a bactericide that represses sulfide production by intestinal anaerobes and N-acetylcysteine as a precursor for glutathione, which can act as a buffer for reduced sulfur.

description: The Anti Collision device is a detection device meant to be incorporated into cars for the purpose of safety. As opposed to the anti collision devices present in the market today, this system is not designed to control the vehicle. Instead, it serves as an alert in the face of imminent collision. The device is intended to find a way to implement a minimum spacing for cars in traffic in an affordable way. It would also achieve safety for the passengers of a moving car. The device is made up of an infrared transmitter and receiver. Also incorporated into it is an audio visual alarm to work in with the receiver and effectively alert the driver and/or the passengers. To achieve this design, 555 timers coupled both as astable and monostable circuits were used along with a 38 KHz Square Pulse generator. The device works by sending out streams of infrared radiation and when these rays are seen by the other equipped vehicle, both are meant to take the necessary precaution to avert a collision. The device would still sound an alarm even though it is not receiving infrared beams from the oncoming vehicle. This is due to reflection of its own infrared beams. At the end of the design and testing process, overall system was implemented with a constructed work, tested working and perfectly functional.

description: Observations and modelling suggest that the fluctuations in magnetised plasmas exhibit scale-dependent anisotropy, with more energy in the fluctuations perpendicular to the mean magnetic field than in the parallel fluctuations and the anisotropy increasing at smaller scales. The scale-dependence of the anisotropy has not been studied in full-orbit simulations of particle transport in turbulent plasmas so far. In this paper, we construct a model of critically balanced turbulence, as suggested by \cite{GoSr1995}, and calculate energetic particle spatial diffusion coefficients using full-orbit simulations. The model uses an enveloped turbulence approach, where each 2-dimensional wave mode with wavenumber $k_\perp$ is packed into envelopes of length $L$ following the critical balance condition, $L\propto k_\perp^{-2/3}$, with the wave mode parameters changing between envelopes. Using full-orbit particle simulations, we find that both the parallel and perpendicular diffusion coefficients increase by a factor 2, compared to previous models with scale-independent anisotropy.

description: The present cumulative habilitation thesis involves fourteen publications of research that aimed at the elucidation of plant physiological and molecular factors and processes determining the adventitious root formation and leaf senescence in shoot tip cuttings of ornamental crops. In this context, the principle influence of cutting excision involving the wounding and isolation of the cutting from the entire stock plant were considered as well as the influences of specific environmental factors affecting the cuttings during the complex chain of global young plant production. After a general introduction into the subject of this thesis, the second part provides an overview summarizing the publications as assigned to the following topics: 1. Influence of beneficial root-colonizing fungi at stock plant and cutting level on rooting of cuttings, 2. Nitrogen and carbohydrate interactions on rooting of cuttings, 3. Involvement of carbohydrate source and sink relations in rooting of cuttings, 4. Involvement of plant hormone pathways in leaf senescence and adventitious root formation in cuttings. After listing of the publications, the discussion part integrates and critically discusses the obtained results in the contemporary context of science. General concepts are derived and an outlook on further needs of research is presented.

Non-Markovian spin transfer dynamics in magnetic semiconductors despite short memory times

description: A quantum kinetic theory of the spin transfer between carriers and Mn atoms in a Mn doped diluted magnetic semiconductor is presented. It turns out that the typical memory time associated with these processes is orders of magnitude shorter than the time scale of the spin transfer. Nevertheless, Markovian rate equations, which are obtained by neglecting the memory, work well only for bulk systems. For quantum wells and wires the quantum kinetic results qualitatively deviate from the Markovian limit under certain conditions. Instead of a monotonic decay of an initially prepared excess electron spin, an overshoot or even coherent oscillations are found. It is demonstrated that these features are caused by energetic redistributions of the carriers due to the energy-time uncertainty.

Ground states of the frustrated Blume-Emery-Griffiths model in a field

Publisher: name: arXiv
Year: 2012
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: Ground-state properties of the Blume-Emery-Griffiths model with antiferromagnetic nearest-neighbor interactions on a triangular lattice are investigated in the presence of an external magnetic field. In particular, we explore the model's parameter space and identify regions with different degenerate ground states that may give rise to different magnetic phases also at finite temperatures. We demonstrate the presence of such phases by Monte Carlo simulations of magnetization processes for selected values of parameters.

Sparse integrative clustering of multiple omics data sets

description: High resolution microarrays and second-generation sequencing platforms are powerful tools to investigate genome-wide alterations in DNA copy number, methylation and gene expression associated with a disease. An integrated genomic profiling approach measures multiple omics data types simultaneously in the same set of biological samples. Such approach renders an integrated data resolution that would not be available with any single data type. In this study, we use penalized latent variable regression methods for joint modeling of multiple omics data types to identify common latent variables that can be used to cluster patient samples into biologically and clinically relevant disease subtypes. We consider lasso [J. Roy. Statist. Soc. Ser. B 58 (1996) 267-288], elastic net [J. R. Stat. Soc. Ser. B Stat. Methodol. 67 (2005) 301-320] and fused lasso [J. R. Stat. Soc. Ser. B Stat. Methodol. 67 (2005) 91-108] methods to induce sparsity in the coefficient vectors, revealing important genomic features that have significant contributions to the latent variables. An iterative ridge regression is used to compute the sparse coefficient vectors. In model selection, a uniform design [Monographs on Statistics and Applied Probability (1994) Chapman & Hall] is used to seek "experimental" points that scattered uniformly across the search domain for efficient sampling of tuning parameter combinations. We compared our method to sparse singular value decomposition (SVD) and penalized Gaussian mixture model (GMM) using both real and simulated data sets. The proposed method is applied to integrate genomic, epigenomic and transcriptomic data for subtype analysis in breast and lung cancer data sets.

description: For two bounded domains in the complex plane whose semigroups of analytic endomorphisms are isomorphic, Eremenko proved in 1993 that the isomorphism is given as a conjugation by a conformal or anticonformal map. In the present paper we prove an analogue of this result for the case of bounded domains in \mathbb C^n.

description: We study the intermediate tachyon inflation in an anisotropic background. By using the Friedmann equations obtained in the anisotropic geometry, we obtain the slow-roll parameters in the tachyon model. The presence of the anisotropic effects in the slow-roll parameters changes the perturbation parameters in our setup which may change its observational viability. To check this, we perform a numerical analysis and test the results with Planck2018 TT, TE, EE +lowE+lensing+BK14(18)+BAO data. We show that the intermediate anisotropic inflation in some ranges of the anisotropic and intermediate parameters is observationally viable. We also show that the equilateral amplitude of the non-gaussianity in our model is of the order of $10^{-2}-10^{-1}$. By studying the reheating process in our setup, we find that it is possible to have instantaneous reheating in this model. We also find that the temperature during the reheating in our setup is consistent with Big-Bang nucleosynthesis.

description: This article is the result of the analysis of various bibliographic reference management tools, especially those that are free. The use of editorial tools by bibliographic editors has evolved rapidly since 2007. But, until recently, free software has fallen short when it comes to ergonomics or use. The functional and technical panorama offered by free software is the result of the comparison of JabRef, Mendeley Desktop, BibDesk and Zotero software undertaken in January 2012 by two research professors affiliated with the Institut national français des techniques de la documentation (INTD).
