description: In this paper, the phenomenon of intergranular fracture in polycrystalline materials is investigated using a nonlinear fracture mechanics approach. The nonlocal cohesive zone model (CZM) for finite thickness interfaces recently proposed by the present authors is used to describe the phenomenon of grain boundary separation. From the modelling point of view, considering the dependency of the grain boundary thickness on the grain size observed in polycrystals, a distribution of interface thicknesses is obtained. Since the shape and the parameters of the nonlocal CZM depend on the interface thickness, a distribution of interface fracture energies is obtained as a consequence of the randomness of the material microstructure. Using these data, fracture mechanics simulations are performed and the homogenized stress-strain curves of 2D representative volume elements (RVEs) are computed. Failure is the result of a diffuse microcrack pattern leading to a main macroscopic crack after coalescence, in good agreement with the experimental observation. Finally, testing microstructures characterized by different average grain sizes, the computed peak stresses are found to be dependent on the grain size, in agreement with the trend expected according to the Hall-Petch law.

description: We describe an application of variational Monte Carlo to two-dimensional fermionic systems within the recently developed tensor-network string-bond state (SBS) ansatz. We use a combination of variational Monte Carlo and stochastic optimization to optimize the matrix-product state matrices representing the ground state. We present results for a two-dimensional spinless fermion model including nearest-neighbor Coulomb interactions and determine using finite-size scaling the phase boundary between charge-ordered insulating and metallic phases. This approach can treat frustrated systems and be easily extended to for fermions with spin.

description: We show that strong coupling between ions in an ultracold neutral plasma is limited by electron screening. While electron screening reduces the quasi-equilibrium ion temperature, it also reduces the ion-ion electrical potential energy. The net result is that the ratio of nearest-neighbor potential energy to kinetic energy in quasi-equilibrium is constant and limited to approximately 2 unless the electrons are heated by some external source. We support these conclusions by reporting new measurements of the ion velocity distribution in an ultracold neutral calcium plasma. These results match previously reported simulations of Yukawa systems. Theoretical considerations are used to determine the screened nearest-neighbor potential energy in the plasma.

description: The MRO industry faces substantial challenges with regard to the capacity planning of disassembly and reassembly work. This is due to the unknown workloads when regenerating complex investment goods and is caused, in particular, by the uncertain degree of disassembly and the complex challenges of reassembly. Forecasting techniques based on Bayesian networks are developed along with mathematical models which optimize capacity utilization, job order and the resulting costs. The approaches are tested and validated in conjunction with an MRO company with global operations. The results show possibilities for enhancing the planning processes and are found to be transferable on an international scale regardless of sociocultural and process differences.

description: In the frame work of Collaborative Research Center (CRC) 653, magnetic data storage on surfaces of components has been developed. The principle is based on magnetic data storage of hard disk drives. Rigid magnetic writing heads successfully developed so far still have limited capabilities; they cannot be adapted to rough or curved surfaces and cannot withstand high mechanical shock. To overcome such drawbacks, a new design of a writing head based on a flexible substrate is proposed. This publication focuses on an investigation of a material which serves as a required substrate for this application. Baseline examinations for asserting compatibility of the flexible substrate to production processes for microelectromechanical systems (MEMS) are presented. Successfully fabricated micro structures using simple fabrication techniques based on photolithography and thin film processes are demonstrated as well. Obtained results through this work indicate that the polyimide film, namely Kapton film, is suitable as the flexible substrate for the flexible magnetic writing / reading system.

description: Using a compilation of 379 massive (stellar mass M > 10^{11} M_Sun) spheroid-like galaxies from the near-infrared Palomar/DEEP-2 survey, we have probed, up to z~1, whether the presence of companions depends on the size of the host galaxies. We have explored the presence of companions with mass ratios down to 1:10 and 1:100, with respect to the central massive galaxy, and within a projected distance of 30, 50 and 100 kpc of these objects. We find evidence for these companions being equally distributed around both compact and extended massive spheroids. This finding suggests that, at least since z~1, the merger activity in these objects is rather homogeneous across the whole population and its merger history is not affected for the size of the host galaxy. Our result could indicate that both compact and extended massive spheroid-like galaxies are growing in size at the same rate.

description: We derive an exact functional renormalization group equation for the projectable version of Hořava-Lifshitz gravity. The flow equation encodes the gravitational degrees of freedom in terms of the lapse function, shift vector and spatial metric and is manifestly invariant under background foliation-preserving diffeomorphisms. Its relation to similar flow equations for gravity in the metric formalism is discussed in detail, and we argue that the space of action functionals, invariant under the full diffeomorphism group, forms a subspace of the latter invariant under renormalization group transformations. As a first application we study the RG flow of the Newton constant and the cosmological constant in the ADM formalism. In particular we show that the non-Gaussian fixed point found in the metric formulation is qualitatively unaffected by the change of variables and persists also for Lorentzian signature metrics.

description: The importance of optical technology as a key technology is constantly increasing. In application areas, where the conventional use of electrical solutions for signal generation, signal transmission or signal reception is limited due to data transfer rates as well as electromagnetic compatibility, optical waveguide technologies are developed and applied. Optical waveguides, essentially fibre systems, are also used as sensors in many applications for measuring physical properties like temperature and elongation. Using multimode fibres, the variation of light intensity is measured to determine the applied changes on its physical properties. Multimode fibres have an average core diameter of 50 μm and are easier to handle than single mode optical fibres but they have less sensitivity and a lower measurement range. Three main steps separate production and use of polymer single-mode optical fibres. The first one includes fibre manufacturing methods. Then the necessary length for the sensor application is selected and the ends of the fibre are prepared and polished. The last step involves optronic assembly and packaging, which consists of integrating the optical fibre onto the surface of the element to be measured and coupling it with optronic devices such as the transmitter and receiver of the light signals. In this paper an approach is presented for a production unit, which combines all these three steps together.

description: A suspended, doubly clamped single wall carbon nanotube is characterized as driven nano-electromechanical resonator at cryogenic temperatures. Electronically, the carbon nanotube displays small bandgap behaviour with Coulomb blockade oscillations in electron conduction and transparent contacts in hole conduction. We observe the driven mechanical resonance in dc-transport, including multiple higher harmonic responses. The data shows a distinct negative frequency tuning at finite applied gate voltage, enabling us to electrostatically decrease the resonance frequency to 75% of its maximum value. This is consistently explained via electrostatic softening of the mechanical mode.

description: We report the de Haas-van Alphen (dHvA) oscillations and first-principle calculations for triangular antiferromagnet PdCrO2 showing unconventional anomalous Hall effect (AHE). The dHvA oscillations in PdCrO2 reveal presence of several 2 dimensional Fermi surfaces of smaller size than found in nonmagnetic PdCoO2. This evidences Fermi surface reconstruction due to the non-collinear 120 antiferromagnetic ordering of the localized Cr, consistent with the first principle calculations. The temperature dependence of dHvA oscillations shows no signature of additional modification of Cr spin structure below TN. Considering that the 120 helical ordering of Cr spins has a zero scalar spin chirality, our results suggest that PdCrO2 is a rare example of the metallic triangular antiferromagnets whose unconventional AHE can not be understood in terms of the spin chirality mechanism.

description: The application of life cycle data of smart products offers new opportunities for the product development process. Nowadays, products often consist of adaptive design variants of an existing product. Taking this into account, the new product development approach called technical inheritance is developed analogous to biological inheritance. This approach considers the intergenerational evolution of design characteristics. Enhanced smart products are developed within the Collaborate Research Center (CRC) 653 called “Gentelligent Components in Their Lifecycle”. These features the capabilities to sense, collect and transfer life cycle data inherently by using genetic product properties and artificial intelligence. By using technical inheritance optimization strategies are currently investigated and the design of gentelligent components is researched. During the technical inheritance various monitoring concepts are applied to realize a targeted algorithmic feedback of lifecycle information from smart products. For a targeted algorithmic feedback of product life cycle information methods of data mining are applied. These include the objectives of data beneficiation as well as information detection. The boundaries of the investigations are determined through the gentelligent components. Therefore highly mechanical loaded systems are in focus. It follows that the physical aspects and specific life cycle incidents are major objects for the monitoring concept of the product life cycle. The approach aims at the integration of an evolutionary algorithm to identify the component specific critical loads as well as the optimal allocation of loads cases. The results of this concept are exemplified by a wheel suspension which is part of the demonstrator of collaborate research center.

description: This study introduces a method based on link analysis to investigate the structure of the R&D support infrastructure associated with science parks in order to determine whether this webometric approach gives plausible results. Three science parks from Yorkshire and the Humber in the UK were analysed with webometric and social network analysis techniques. Interlinking networks were generated through the combination of two different data sets extracted from three sources (Yahoo!, Bing, SocSciBot). These networks suggest that institutional sectors, representing business, universities and public bodies, are primarily tied together by a core formed by research institutions, support structure organisations and business developers. The comparison of the findings with traditional indicators suggests that the web-based networks reflect the offline conditions and policy measures adopted in the region, giving some evidence that the webometric approach is plausible to investigating science park networks. This is the first study that applies a web-based approach to investigate to what extent the science parks facilitate a closer interaction between the heterogeneous organisations that converge in R&D networks. This indicates that link analysis may help to get a first insight into the organisation of the R&D support infrastructure provided by science parks.

description: We present two novel approaches to 2D optical strain sensing in thin polymer foils that allow for mass-production by MEMS production techniques. The sensor principles are based on purely optical methods: the sensitive detection of either wavelength or intensity transfer functions in specifically designed planar waveguide structures. The goal is to develop 2D strain sensor arrays that are easy to integrate in flexible polymer foils and which can be applied to a wide range of measurement applications in research and technology. We discuss the sensor concepts and analyze their performance under optimal conditions.

description: Magnetic magnesium alloys have an inherent load-sensitive behavior. These alloys are manufactured by casting of magnesium alloyed with the ferromagnetic element cobalt. In this context, the magnetoelastic effect can be used in order to measure mechanical loads during the component's service by means of a harmonic analysis of eddy current signals. The utilization of magnetic magnesium as a load-sensitive material in order to measure mechanical loads in structural components has been demonstrated in previous works. Another application is the magnetic labeling of the alloy. In this context the magnetic remanence is a significant characteristic value. A data track can be written directly on the material's surface by means of an electromagnetic write head. The track may contain relevant component-specific information like serial numbers, manufacture date and expected lifetime. This information can be read out by means of a sensor utilizing the giant magnetoresistive (GMR) effect. The magnetic labeling in relation to the manufactured alloy and the cooling rate during the casting process is examined in this work. The magnetic labeling of three alloys based on magnesium, cobalt and zinc has been investigated; these are MgCo4 and MgCo4Zn2. The alloys’ mechanical as well as their magnetic properties are significantly influenced by these additional alloying elements. In order to investigate the alloys’ suitability for magnetic data storage the quality of the data tracks read out using a GMR sensor are compared depending on the alloy composition. The magnetic labeling is influenced by the microstructure regarding solidification and cooling rate. A conical casting geometry with different solidification rates in top and bottom sections was used for an examination of the relationship between the density of the magnetic phases and the quality of the magnetic labeling.

description: We study the structure of the gauge propagators of a 3d version of the electroweak interaction in terms of the Higgs vacuum expectation value nu, of the non-Abelian gauge coupling g, and of the Abelian gauge coupling g', when nonperturbative effects related to the non-Abelian gauge fixing are introduced by means of an adapted path integral measure. In the perturbative regime of small non-Abelian coupling g and sufficiently large nu, the well-known standard Z and W propagators are recovered, together with a massless photon. In general, depending on the relative magnitudes of g, g' and nu, we uncover a quite different propagator structure. In a later stage of research, the results here derived can be used to study the associated phase diagram in more depth.

description: A search for excited state transitions of double beta decay in Pd110 and double electron capture in Pd102 has been performed in the HADES underground laboratory with two low background HPGe detectors in sandwich configuration. After an exposure of 35.92 kg*d, no signal was found. The frequentist spectral analysis resulted in lower half-life limits of 1.98e20 yr and 1.72e20 yr (95% CL) for the first 0+ and 2+ excited state in Pd110 respectively. This is an improvement by more than a factor of 3 with respect to previous measurements. In Pd102, the lower half-life limit could be improved to 5.95e18 yr (95% CL) for the first 0+ excited state. Furthermore, first experimental lower half-live limits are found for all possible excited states in the Pd110 and Pd102 systems.

description: Ab initio density functional theory has been used to analyze flexural modes, elastic constants, and atomic corrugations on single and bi-layer graphene. Frequencies of flexural modes are sensitive to compressive stress; its variation under stress can be related to the anomalous thermal expansion via a simple model based in classical Elasticity Theory [Phys. Rev. B 86, 144103]. Under compression, flexural modes are responsible for a long wavelength rippling with a large amplitude and a marked anharmonic behavior. This is compared with corrugations created by thermal fluctuations and the adsorption of a light impurity (hydrogen). Typical values for the later are in the sub-Angstrom regime, while maximum corrugations associated to bending modes quickly increase up to a few Angstroms under a compressive stress, due to the intrinsic instability of flexural modes

description: Magnetic field sensors are used for contact free position detection of machine components for example. Fabricating these sensors on a flexible substrate enables the user to attach the sensor on various surfaces and different installation situations. Within the Collaborated Research Center 653 a modular anisotropic magnetic field sensor on a flexible polymer substrate has been developed. In a next step the sensor should be transferred into an industrial application.

description: Разработка системы, которая позволит проводить объективный контроль состояния посе-вов является важной и актуальной задачей, ее решение даст возможность оценивать ход формирования урожая, применять оперативные мероприятия по уходу за посевами, а так-же более точно прогнозировать урожайность сельскохозяйственных культур. Предложенный способ оценки динамики продуктивности в течение вегетации позволяет контролировать ход формирования урожая сельскохозяйственных культур для такой большой территории как Ставропольский край. Аналогично, такую методологию можно использовать для отдельных районов, и почвенно-климатических зон.
description: The development of a system that will allow for objective monitoring of the state of crops is an important and urgent task; its solution will make it possible to assess the course of crop formation, apply operational measures to care for crops, and more accurately predict crop yields. The proposed method for assessing the dynamics of productivity during the growing season allows you to control the course of crop formation for such a large territory as the Stavropol Territory. Similarly, such a methodology can be used for individual areas, and soil and climate zones.

description: Structural aircraft components are usually manufactured from rolled plate material. Despite a stress relief treatment residual stress remains in the plates. This can result in distortions of the workpiece after the final manufacturing step, which leads to time-consuming repair processes or even a scrap part. Using an FEM simulation, it is possible to predict distortions caused by residual stress and to avoid them by adjusting the manufacturing process. However, the known methods to determine the residual stress state in plate material are expensive in terms of time and material and require specially trained staff. This paper describes a novel method to measure residual stress in plates with little effort. The method is derived from the well-known Layer-Removal-Method and utilizes a machine tool with a standard probing device. The measuring task is fully automated and can be performed by untrained staff. No special preparation of the specimen is necessary. The paper describes the procedure and the results of residual stress measurement on samples of the material EN AW-7075 T651. The results are in line with values published by other authors.

Planar relative Schottky sets and quasisymmetric maps

description: A relative Schottky set in a planar domain D is a subset of D obtained by removing from D open geometric discs whose closures are in D and are pairwise disjoint. In this paper we study quasisymmetric and related maps between relative Schottky sets of measure zero. We prove, in particular, that quasisymmetric maps between such sets in Jordan domains are conformal, locally bi-Lipschitz, and that their first derivatives are locally Lipschitz. We also provide a locally bi-Lipschitz uniformization result for relative Schottky sets in Jordan domains and establish rigidity with respect to local quasisymmetric maps for relative Schottky sets in the unit disc.

description: In the ongoing search for new negative electrode materials for lithium-ion batteries, amorphous silicon with a theoretical specific capacity of almost 4000 mA h g−1 is still one of the most promising candidates. In order to optimize cycling behavior, prelithiation of silicon is discussed as possible solution. Yet, little is known about kinetics in the Li-Si system, especially with a low lithium content. Using neutron reflectometry as a tool, lithium permeation through amorphous LixSi layers was probed during annealing. From the results a lithium permeability (diffusivity×solubility) of P=(3.3±0.9)×10−21 m2 s−1 is derived for LixSi (x≈0.1), which is identical to that of pure amorphous silicon.
Solitaire Clobber Played on Hamming Graphs

description: The one-player game Solitaire Clobber was introduced by Demaine et al. Beaudou et al. considered a variation called SC2. Black and white stones are located on the vertices of a given graph. A move consists in picking a stone to replace an adjacent stone of the opposite color. The objective is to minimize the number of remaining stones. The game is interesting if there is at least one stone of each color. In this paper, we investigate the case of Hamming graphs. We prove that game configurations on such graphs can always be reduced to a single stone, except for hypercubes. Nevertheless, hypercubes can be reduced to two stones.

description: Lithium-intercalating materials such as graphite are of great interest, especially for application in lithium-ion batteries. In this work we present an investigation of the electrochemical performance of mesocarbon microbeads (MCMB) modified with copper to reveal the basic electrochemical mechanisms. Copper-modified graphite is known to have better long-term cycling behavior as well as higher capacity compared to the pristine material. Several reasons for these effects were postulated but not proven. Solid-state nuclear magnetic resonance (NMR) spectroscopy provides structural and dynamic information on lithium in ionic conductors. To elucidate the changes in structure and dynamics for the pristine and the modified material, we have employed multi-nuclear solid-state NMR spectroscopy as well as 7Li spin-lattice relaxation measurements and were able to clarify some reasons for the improved characteristics of copper-modified graphite compared to the pristine material, which include increased solid-electrolyte interface (SEI) formation, a facilitated diffusion of lithium ions through the SEI, and reduced moisture.

description: Numerical results for the distributions of light transmitted through metallic planar lenses composed of symmetric nanogroove arrays on the surfaces of a gold film are presented and explained. Both the near- and far-field distributions of the intensity of light transmitted are calculated by using a Green's function formalism. Results for an optimal transverse focus based on a quadratic variation of groove width are obtained. Meanwhile, a significant dependence of the focal length on the wavelength of light incident from the air side through the gold film into a dielectric substrate is found for this detector configuration.

description: The recent completion of the rose genome sequence is not the end of a process, but rather a starting point that opens up a whole set of new and exciting activities. Next to a high-quality genome sequence other genomic tools have also become available for rose, including transcriptomics data, a high-density single-nucleotide polymorphism array and software to perform linkage and quantitative trait locus mapping in polyploids. Rose cultivars are highly heterogeneous and diverse. This vast diversity in cultivated roses can be explained through the genetic potential of the genus, introgressions from wild species into commercial tetraploid germplasm and the inimitable efforts of historical breeders. We can now investigate how this diversity can best be exploited and refined in future breeding work, given the rich molecular toolbox now available to the rose breeding community. This paper presents possible lines of research now that rose has entered the genomics era, and attempts to partially answer the question that arises after the completion of any draft genome sequence: ‘Now that we have “the” genome, what’s next?’. Having access to a genome sequence will allow both (fundamental) scientific and (applied) breeding-orientated questions to be addressed. We outline possible approaches for a number of these questions.
