description: We present new theoretical estimates of the relative contributions of unresolved blazars and star-forming galaxies to the extragalactic gamma-ray background (EGB) and discuss constraints on the contributions from alternative mechanisms such as dark matter annihilation and truly diffuse gamma-ray production. We find that the Fermi source count data do not rule out a scenario in which the EGB is dominated by emission from unresolved blazars, though unresolved star-forming galaxies may also contribute significantly to the background, within order-of-magnitude uncertainties. In addition, we find that the spectrum of the unresolved star-forming galaxy contribution cannot explain the EGB spectrum found by EGRET at energies between 50 and 200 MeV, whereas the spectrum of unresolved FSRQs, when accounting for the energy-dependent effects of source confusion, could be consistent with the combined spectrum of the low-energy EGRET EGB measurements and the Fermi-LAT EGB measurements.

description: Report Summary: Certified seed potatoes were cut from 60 to 150 days before planting, treated with chemicals, and stored in bulk bins or pallet boxes until planted. The resulting stands and yields were equal to or greater than those obtained with fresh-cut seed. Mertect and Benlate provided the highest control of seed piece decay. Bulk hopper railcars, pallets, and conventional 100-pound burlap bags were satisfactory for precut seed shipment. Descriptions of equipment, procedures, and structure plans are included as well as recommendations for precutting seed. An economic analysis showed that the cost of precutting seed ranged from about $0.12 to $1.30 per hundredweight.

description: We theoretically investigate the spin dynamics of a heavy hole confined to an unstrained III-V semiconductor quantum dot and interacting with a narrowed nuclear-spin bath. We show that band hybridization leads to an exponential decay of hole-spin superpositions due to hyperfine-mediated nuclear pair flips, and that the accordant single-hole-spin decoherence time T2 can be tuned over many orders of magnitude by changing external parameters. In particular, we show that, under experimentally accessible conditions, it is possible to suppress hyperfine-mediated nuclear-pair-flip processes so strongly that hole-spin quantum dots may be operated beyond the `ultimate limitation' set by the hyperfine interaction which is present in other spin-qubit candidate systems.

At non-chiral values, a new term in the Fefferman-Graham expansion is needed to capture the bulk degree of freedom.

description: Transport events in turbulent tokamak plasmas often exhibit non-local or non-diffusive action at a distance features that so far have eluded a conclusive theoretical description. In this paper a theory of non-local transport is investigated through a Fokker-Planck equation with fractional velocity derivatives. A dispersion relation for density gradient driven linear drift modes is derived including the effects of the fractional velocity derivative in the Fokker-Planck equation. It is found that a small deviation (a few percent) from the Maxwellian distribution function alters the dispersion relation such that the growth rates are substantially increased and thereby may cause enhanced levels of transport.

Nonperturbative renormalization-group approach to strongly-correlated lattice bosons

description: We present a nonperturbative renormalization-group approach to the Bose-Hubbard model. By taking as initial condition of the renormalization-group flow the (local) limit of decoupled sites, we take into account both local and long-distance fluctuations in a nontrivial way. This approach yields a phase diagram in very good quantitative agreement with quantum Monte Carlo simulations, and reproduces the two universality classes of the superfluid--Mott-insulator transition. The critical behavior near the multicritical points, where the transition takes place at constant density, agrees with the original predictions of Fisher {\it et al.} [Phys. Rev. B {\bf 40}, 546 (1989)] based on simple scaling arguments. At a generic transition point, the critical behavior is mean-field like with logarithmic corrections in two dimensions. In the weakly-correlated superfluid phase (far away from the Mott insulating phase), the renormalization-group flow is controlled by the Bogoliubov fixed point down to a characteristic (Ginzburg) momentum scale $k_G$ which is much smaller than the inverse healing length $k_h$. In the vicinity of the multicritical points, when the density is commensurate, we identify a sharp crossover from a weakly- to a strongly-correlated superfluid phase where the condensate density and the superfluid stiffness are strongly suppressed and both $k_G$ and $k_h$ are of the order of the inverse lattice spacing.

description: We study the few-body physics of trapped atoms or molecules with electric or magnetic dipole moments aligned by an external field. Using exact numerical diagonalization appropriate for the strongly correlated regime, as well as a classical analysis, we show how Wigner localization emerges with increasing coupling strength. The Wigner states exhibit non-trivial geometries due to the anisotropy of the interaction. This leads to transitions between different Wigner states as the tilt angle of the dipoles with the confining plane is changed. Intriguingly, while the individual Wigner states are well described by a classical analysis, the transitions between different Wigner states are strongly affected by quantum statistics. This can be understood by considering the interplay between quantum-mechanical and spatial symmetry properties. Finally, we demonstrate that our results are relevant to experimentally realistic systems.

The first nontrivial order in the 1/$N$ expansion is known for any value of $Nα$, and there are also various indications as to the nature of higher order effects. The singularity structure as a function of $Nα$ has implications for the existence of nontrivial fixed points.

These algebras are the analogs of the algebras of spherical functions considered by R. Godement for groups with large compact subgroups. If K=G is a compact group or a compact quantum group, the algebras S_{π} are stably isomorphic with the fixed point algebras A{\otimes}B(H_{π})^{α{\otimes}adπ} where H_{π} is the Hilbert space of the representation π.

The Flare-energy Distributions Generated by Kink-unstable Ensembles of Zero-net-current Coronal Loops

description: It has been proposed that the million degree temperature of the corona is due to the combined effect of barely-detectable energy releases, so called nanoflares, that occur throughout the solar atmosphere. Alas, the nanoflare density and brightness implied by this hypothesis means that conclusive verification is beyond present observational abilities. Nevertheless, we investigate the plausibility of the nanoflare hypothesis by constructing a magnetohydrodynamic (MHD) model that can derive the energy of a nanoflare from the nature of an ideal kink instability. The set of energy-releasing instabilities is captured by an instability threshold for linear kink modes. Each point on the threshold is associated with a unique energy release and so we can predict a distribution of nanoflare energies. When the linear instability threshold is crossed, the instability enters a nonlinear phase as it is driven by current sheet reconnection. As the ensuing flare erupts and declines, the field transitions to a lower energy state, which is modelled by relaxation theory, i.e., helicity is conserved and the ratio of current to field becomes invariant within the loop. We apply the model so that all the loops within an ensemble achieve instability followed by energy-releasing relaxation. The result is a nanoflare energy distribution. Furthermore, we produce different distributions by varying the loop aspect ratio, the nature of the path to instability taken by each loop and also the level of radial expansion that may accompany loop relaxation. The heating rate obtained is just sufficient for coronal heating. In addition, we also show that kink instability cannot be associated with a critical magnetic twist value for every point along the instability threshold.
Observation of drift and diffusion processes in Ti/TiOx/Ti memristive devices prepared by local anodic oxidation

description: We demonstrate that memristive devices can be fabricated by tip-induced oxidation of thin metallic films using atomic force microscope. Electrical measurements of such prepared Ti/TiOx/Ti test structures confirmed their memristive behavior and inferred diffusion of oxygen vacancies in the TiOx barrier. Consequent Kelvin probe force microscopy studies provided evidence for the diffusion, as well as for expected oxygen vacancy drift. Time evolution of the space distribution of the vacancies due to the diffusion process revealed minute-scale (at least) retention times of the devices. The work presents technology alternative for fabrication of memristive nanodevices in geometry favouring advantageous scanning probe microscopy studies of their in-barrier processes, as well as widely utilizable approach to search for novel oxide materials for perspective memristive applications.

description: Photons as well as quarks and gluons are constituents of the infinite momentum frame (IMF) wave function of an energetic particle. They are mostly equivalent photons whose amplitude follows from the Lorentz transformation of the particle rest frame Coulomb field into the IMF and from the conservation of the electromagnetic current. We evaluate in a model independent way the dominant photon contribution \propto α_{em}(Z^2/A^{4/3})\ln(1/R_{A}m_{N}x) to the nuclear structure functions as well as the term \propto α_{em}Z/A. In addition we show that the definition of x consistent with the exact kinematics of eA scattering (with exact sum rules) works in the same direction as the nucleus field of equivalent photons. Combined, these effects account for the bulk of the EMC effect for x\le 0.5 where Fermi motion effects are small. In particular for these x the hadronic mechanism contribution to the EMC effect does not exceed \sim 3% for all nuclei. Also the A-dependence of the hadronic mechanism of the EMC effect for x > 0.5 is significantly modified.

description: We consider the distribution $P(ϕ)$ of the Hatano-Sasa entropy, $ϕ$, in reversible and irreversible processes, finding that the Crooks relation for the ratio of the pdf's of the forward and backward processes, $P_F(ϕ)/P_R(-ϕ)=e^ϕ$, is satisfied not only for reversible, but also for irreversible processes, in general, in the adiabatic limit of "slow processes." Focusing on systems with a finite set of discrete states (and no absorbing states), we observe that two-state systems always fulfill detailed balance, and obey Crooks relation. We also identify a wide class of systems, with more than two states, that can be "coarse-grained" into two-state systems and obey Crooks relation despite their irreversibility and violation of detailed balance. We verify these results in selected cases numerically.

description: A discrete-time version of the replicator equation for two-strategy games is studied. The stationary properties differ from that of continuous time for sufficiently large values of the parameters, where periodic and chaotic behavior replace the usual fixed-point population solutions. We observe the familiar period-doubling and chaotic-band-splitting attractor cascades of unimodal maps but in some cases more elaborate variations appear due to bimodality. Also unphysical stationary solutions have unusual physical implications, such as uncertainty of final population caused by sensitivity to initial conditions and fractality of attractor preimage manifolds.

description: The aim of the European Union to drastically reduce greenhouse gas emissions in the following decades has a great influence on the transport and the energy sector. Electric vehicles and renewable energy sources are seen as outstanding possibilities on this way. An interrelation of these technologies seems to be a promising option. In our contribution we address some challenges, which come along with this interrelation. From a system perspective, more flexibility is needed. One option is to extend flexible demand through dynamic pricing, which timulates a demand response. Electric vehicles can contribute to this objective when the comprehensive load shifting potentials are activated. In addition, the application of local storage devices is discussed to relieve local grids and support the integration of decentralized electricity generation by renewable energy sources.
In this contribution we analyze the effects of dynamic pricing for controlled and bi-directional charging of electric vehicles and the use of stationary battery systems in an urban electricity system. Therefore, we developed an optimization model for the application planning of the charging processes of electric vehicles and stationary storage systems. We demonstrate the high technical and economic potential for load shifting of the charging processes of electric vehicles with controlled charging. Furthermore, we identified positive and negative effects of real time pricing and load limits concerning cost and emission reductions and effects on grid loads. Only the use of stationary battery systems at home together with a load limit has positive effects for integrating photovoltaics and foster CO2 emission reductions. With real time pricing the stationary battery systems are used for arbitrage at the day-ahead market.

description: Physarum Polycephalum is a slime mold that is apparently able to solve shortest path problems. A mathematical model has been proposed by biologists to describe the feedback mechanism used by the slime mold to adapt its tubular channels while foraging two food sources s0 and s1. We prove that, under this model, the mass of the mold will eventually converge to the shortest s0 - s1 path of the network that the mold lies on, independently of the structure of the network or of the initial mass distribution. This matches the experimental observations by the biologists and can be seen as an example of a "natural algorithm", that is, an algorithm developed by evolution over millions of years.

description: Die Generation 50+ hat Social Media mittlerweile fest in ihren Alltag integriert und verankert. Steigende Nutzerzahlen zeigen die wachsende Bedeutung, aber auch die hohe Akzeptanz der Social Media-Plattformen. Studien zeigen, dass die Generation 50+, die hinsichtlich ihrer Anzahl als größte Bevölkerungsgruppe in Österreich angesehen wird, vorrangig Facebook nutzt. In der Literatur werden verschiedene Einflussfaktoren und Motive genannt, die Auswirkungen auf die Nutzung von Social Media haben. In keiner vorliegenden Studie wurde bislang jedoch aufgezeigt, wie sich ausgewählte Faktoren auf die Nutzung von Facebook durch die Generation 50+ auswirken. Auf Basis der erarbeiteten theoretischen Erkenntnisse werden Hypothesen aufgestellt, die mithilfe einer quantitativen Erhebung in Form eines Online-Fragebogens geprüft werden. Die statistischen Auswertungen der erhobenen Daten geben Aufschluss darüber, dass verschiedene Einflussfaktoren und Motive signifikante Auswirkungen auf die Nutzungshäufigkeit von Facebook durch die Generation 50+ haben. Zusammenfassend liefern die Ergebnisse der vorliegenden Masterarbeit Hinweise darüber, wie sich ausgewählte Faktoren auf die Nutzung auswirken.
description: The generation 50+ has now firmly integrated and anchored social media in their everyday lives. Rising user numbers show the growing importance, but also the high acceptance of social media platforms. Studies show that the generation 50+, which is considered the largest population group in Austria in terms of numbers, primarily uses Facebook. In the literature, various influencing factors and motives are mentioned that have an impact on the usage of social media. However, no existing study has yet shown how selected factors affect the usage of Facebook by the 50+ generation. Based on the theoretical findings, hypotheses are formulated which are tested with the help of a quantitative survey in the form of an online questionnaire. The statistical analyses of the data collected indicate that various influencing factors and motives have a significant impact on the frequency of Facebook use by the 50+ generation. In summary, the results of this master thesis provide indications of how selected factors affect usage.

description: Haemorrhagic Septicaemia was recognized as the most foremost killer disease among cattle and buffaloes in Sri Lanka for almost five decades since its detection in mid nineteen fifties. A retrospective study was carried out to analyze the occurrence pattern describing the epidemiological features and major control measures applied in the country during a period of fifteen years since 1996. The last clinical case was detected at Millaniya in Kalutara district in 2004. Nonexistence of the disease in its clinical form has diminished the prophylactic vaccination since 2009
Resonant relaxation and the warp of the stellar disc in the Galactic centre

description: Observations of the spatial distribution and kinematics of young stars in the Galactic centre can be interpreted as showing that the stars occupy one, or possibly two, discs of radii ~0.05-0.5 pc. The most prominent (`clockwise') disc exhibits a strong warp: the normals to the mean orbital planes in the inner and outer third of the disc differ by ~60 deg. Using an analytical model based on Laplace-Lagrange theory, we show that such warps arise naturally and inevitably through vector resonant relaxation between the disc and the surrounding old stellar cluster.

description: Heutige Konsument*innen erwarten sich von Pure-Online-Playern in der B2C-Gebrauchsgüterbranche einzigartige holistische Erlebnisse. Diese können mit einer Omnichannel-Excellence und den damit verbundenen strategischen, taktischen als auch operativen Maßnahmen erreicht werden. Die Wahl stationärer Store-Konzepte basierend auf Konsumentenpräferenzen bildet innerhalb der Omnichannel-Strategie ausgehend von Pure-Online-Playern eine zentrale Entscheidung im individuellen Unternehmenskontext. Daher ergab sich folgende Forschungsfrage: Welche stationären Store-Konzepte präferieren österreichische Konsument*innen bei B2C-Gebrauchsgüter-Pure-Online-Playern zur Erreichung einer holistischen Customer Experience? Zur Beantwortung wurde eine quantitative Studie zu Präferenzen nach den dominierenden Store-Konzepten im Omnichannel für Pure-Online-Player durchgeführt. Die Ergebnisse verdeutlichen, dass alle drei herangezogenen Store-Konzepte (Showroom, Pop-up-Store und Flagship-Store) in der expressiven B2C-Gebrauchsgüterbranche ausgehend von Pure-Online-Playern grundsätzlich präferiert werden, wenn es sich um österreichische Konsument*innen handelt. Der Pop-up-Store jedoch eignet sich vorrangig für die Zielgruppe der Frauen und Personen ohne Matura.
description: Today’s consumers expect unique, holistic experiences from pure online players in the B2C durable goods sector. This can be achieved by means of omnichannel-excellence and the related strategic, tactical, and operational measures. For pure online players, choosing a stationary store concept based on consumer preferences poses a central decision within the omnichannel strategy of the individual company. Therefore, the following research question arose: Which stationary store concepts do Austrian consumers prefer from B2C durable goods pure online players regarding the achievement of a holistic customer experience? To answer this, a quantitative study about the preferences for the dominant store concepts in an omnichannel context for pure online players was conducted. The results show that all three store concepts (showroom, pop-up store, and flagship store) are generally preferred by Austrian consumers regarding pure online players in the expressive B2C durable goods sector. Pop up stores, however, are most suitable if the target consumers are women or people without A-levels.

description: This deliverable aims to present the methods employed, tools used, results, and presents conclusions of the participatory process carried out at island level in SOCLIMPACT to propose, rank and evaluate alternative adaptation pathways to face climate change impacts. A framework was set for a presential consultation method but with the arrival of the COVID-19 pandemic context major adjustments had to be made to what was originally proposed. The Adaptation pathways rational and concept is presented explaining how the sector adaptation pathways were designed, how the proposed Adaptation Options were assembled in classes of adaptation and how Adaptation Policy Trajectories (APTs) were used as context to develop alternative adaptation pathways. The development and characterization of those Adaptation Options is explained, putting forward how these policy options were gathered at European level and then traduced and characterized to the island level.

description: Lepton flavor violation in tau and mu processes is studied in the littlest Higgs model with T-parity. We consider various asymmetries defined in polarized tau and mu decays. Correlations among branching ratios and asymmetries are shown in the following lepton flavor violation processes: mu+ --> e+ gamma, mu+ --> e+ e+ e-, mu- A --> e- A (A = Al, Ti, Au and Pb), tau+ --> mu+ gamma, tau+ --> mu+ mu+ mu-, tau+ --> mu+ e+ e-, tau+ --> mu+ P (P = pi0, eta and eta'), tau+ --> mu+ V (V = rho0, omega and phi), tau+ --> e+ gamma, tau+ --> e+ e+ e-, tau+ --> e+ mu+ mu-, tau+ --> e+ P, tau+ --> e+ V, tau+ --> mu+ mu+ e- and tau+ --> e+ e+ mu-. It is shown that large parity asymmetries and time-reversal asymmetries are allowed in mu+ --> e+ e+ e-. For tau lepton flavor violation processes, sizable asymmetries are possible reflecting characteristic chirality structure of lepton flavor violating interactions in this model.

description: We investigate the parameter spaces of hybrid inflation model with special attention paid to the dynamics of waterfall field and curvature perturbations induced from its quantum fluctuations. Depending on the inflaton field value at the time of phase transition and the sharpness of the phase transition inflation can have multiple extended stages. We find that for models with mild phase transition the induced curvature perturbation from the waterfall field is too large to satisfy the COBE normalization. We investigate the model parameter space where the curvature perturbations from the waterfall quantum fluctuations vary between the results of standard hybrid inflation and the results obtained here.

description: Die Verankerung von Social Media in der Marketingstrategie ist im 21. Jahrhundert essenziell. Es reicht jedoch nicht aus, nur auf Online-Maßnahmen zu setzen, um international erfolgreich zu sein. Eine strategische Planung sozialer Medien wird für Unternehmen zunehmend wichtiger. Besonders global agierende Unternehmen müssen ihren Auftritt in verschiedenen Märkten sorgfältig planen. Dazu ist ein umfassendes Verständnis darüber erforderlich, wie soziale Medien in den verschiedenen Märkten genutzt werden und welche kulturellen Unterschiede zwischen den Zielmärkten bestehen. Die vorliegende Masterarbeit beschäftigt sich mit der Frage, ob es Performance-Unterschiede zwischen standardisierten und lokalisierten Social-Media-Anzeigen gibt. Dafür wird eine zweiteilige Forschung in den Märkten DACH und UKI durchgeführt und geprüft, wie die unterschiedlichen Anzeigen in den Zielmärkten performen, welche Rolle dabei die Kultur spielt und wie Konsument*innen dazu stehen. Die Feldforschung zeigt auf, dass die Zielmärkte die beiden Varianten unterschiedlich wahrnehmen und eine Lokalisierung der Social-Media-Anzeigen bei Kampagnen zur Leadgenerierung besonders wichtig ist. Grundsätzlich sollten Unternehmen zumindest einen Glokalisierungsansatz anstreben, um Kund*innen von ihnen zu überzeugen und international erfolgreich zu sein.
description: In the 21st century incorporating social media into a company's marketing strategy is essential. However, it is not enough to rely solely on online marketing activities in order to stand out from the competition and be successful internationally. Strategic planning and use of social media are becoming increasingly important for companies. In particular globally active players must carefully plan and successfully implement their presence in their target markets. This requires a comprehensive understanding of how social media can be used in different markets and what cultural differences exist between them. This master thesis addresses the question of whether there are performance differences between standardized and localized social media ads. For this purpose, a two-part empirical research is conducted in the DACH and UKI markets and examined how the different ads perform in the target markets, which role the culture of the country plays and how consumers feel about it. The field research shows that the target markets perceive standardized and localized ads differently and that localization of social media ads is particularly important for campaigns with the goal of lead generation. Basically, companies should at least strive to implement a glocalization approach in order to convince customers of their products and services and to be successful internationally.

description: We expand the study of generalized brane cosmologies by allowing for an $f(\tilde{\cal R})$ gravity term on the brane, with $\tilde{\cal R}$ the curvature scalar derived from the induced metric. We also include arbitrary matter components on the brane and in the five-dimensional bulk. At low energies, the effect of the bulk on the brane evolution can be described through a mirage component, termed generalized dark radiation, in the effective four-dimensional field equations. Using the covariant formalism, we derive the exact form of these equations. We also derive an effective conservation equation involving the brane matter and the generalized dark radiation. At low energies the coupled brane-bulk system has a purely four-dimensional description. The applications of the formalism include generalizations of the Starobinsky model and the Dvali-Gabadadze-Porrati cosmology.

description: During the design of a security architecture for a web application, the usage of security patterns can assist with fulfilling quality attributes, such as increasing reusability or safety. The attack surface is a common indicator for the safety of a web application, thus, reducing it is a problem during design. Today’s methods for attack surface reduction are not connected to security patterns and have an unknown impact on quality attributes, e.g., come with an undesirable trade-off in functionality. This paper introduces a systematic and deterministic method to reduce the attack surface of web services by deriving service interface methods from authorization patterns. We applied the method to the Participation Service that is part of the KIT Smart Campus system. The resulting RESTful web services of the application are presented and validated.
