description: Quasiparticle relaxation rate,$τ_{p}^{-1}$, and the shear viscosity tensor of the A_1-phase of superfluid 3He are calculated at low temperatures and melting pressure, by using Boltzmann equation approach in momentum space. The collision integral is written in terms of inscattering and outscattering collision integrals. The interaction between normal and Bogoliubov quasiparticles is considered in calculating transition probabilities in the binary, decay and coalescence processes. We obtain that both $τ_{p\uparrow}^{-1}$ and $τ_{p\downarrow}^{-1}$ are proportional to $T^2$ >. The shear viscosities $η_{xy}$, $η_{xz}$ and $η_{zz}$ are proportional to $(T/T_c)^{-2}$. The constant of proportionality of the shear viscosity tensor is in nearly good agreement with the experimental results of Roobol et al., and our exact theoretical calculation.

description: This thesis is aimed at assessing the basic economic viability of decentralized hydrogen fuel electrolysis in the Austrian market. As a rst step, expert studies are investigated for establishing driving factors of the economic viability of such systems. Based on these studies, scenarios with speci c projections for all major driving factors are derived, which are later used as input for the economic viability model of a single decentralized hydrogen fuel electrolysis system. The second main part of the thesis suggests a techno-economic model for both the operational feasibility and investment viability of a decentralized hydrogen fuel electrolysis plant. After discussing the established model, different deployment options are exercised with the matching input values of the scenario projections from the rst part of the thesis. Based on the results, the economic viability of each deployment option is studied. Finally, a conclusion based on all results is presented, while also giving an outlook for additional studies to be carried out for further examining the topic at hand.

description: Представлен краткий литературный обзор имеющихся научных данных о развитии аллергических реакций на фоне ВИЧ-инфекции. Рассмотрены основные статистические сведения по ВИЧ-инфекции и аллергическим заболеваниям на территории Российской Федерации. В статье даны сведения о развитии аллергических реакций у ВИЧ-инфицированных пациентов на основании клинических и лабораторных данных. Особое внимание при изучении аллергий у ВИЧ-инфицированных отводится лекарственной аллергии, так как аллергические реакции на определенные лекарственные препараты могут усложнить подбор антиретровирусной терапии и лечения коморбидных состояний. Лекарственная аллергия рассмотрена для каждой из основных групп лекарственных препаратов, применяемых для антиретровирусной терапии ВИЧ-инфицированных пациентов, приведены конкретные примеры антиретровирусных препаратов, на которые чаще всего развивается аллергическая реакция.
The relation between black hole mass and velocity dispersion at z~0.37

description: The velocity dispersion of 7 Seyfert 1 galaxies at z~0.37 is measured using high signal-to-noise Keck spectra. Black hole (BH) mass estimates are obtained via an empirically calibrated photoionization method. We derive the BH mass velocity dispersion relationship at z~0.37. We find an offset with respect to the local relationship, in the sense of somewhat lower velocity dispersion at a fixed BH mass at z~0.37 than today, significant at the 97% level. The offset corresponds to Delta log sigma = -0.16 with rms scatter of 0.13 dex. If confirmed by larger samples and independent checks on systematic uncertainties and selection effects, this result would be consistent with spheroids evolving faster than BHs in the past 4 Gyrs and inconsistent with pure luminosity evolution.

description: This article presents a multi-temporal uncertainty-based method that incorporates a statistical regression model with a view to establishing the risk (probability) of land cover changes as a function of a set of environmental and socio-economic driving factors. The morphologic, climatic and socio-economic variables were examined using an Artificial Neural Network (ANN) model and the Multi-Layer Perceptron (MLP). Following the analysis, maps indicating the suitability to future changes were generated on the basis of observed transitions. From these maps two possible land use scenarios were built, applying the Markov chain principle. The region of Basilicata, in southern Italy, was selected for the analysis. The results highlight: a) a good inclination to change towards specialised crop systems, provided there is sufficient water supply; b) that some cropping patterns are not suitable for changes, partly because they are found in a context with severe limitations for alternative uses.

description: By using new and previous measurements of the $ab$-plane conductivity $σ_1^{ab} (ω,T)$ of La$_{2-x}$Sr$_x$CuO$_{4}$ (LSCO) it is shown that the spectral weight $W = \int_0^Ω{σ_1^{ab} (ω,T) dω}$ obeys the same law $W = W_0 - B(Ω) T^2$ which holds for a conventional metal like gold, for $Ω$'s below the plasma frequency. However $B(Ω)$, which measures the "thermal response" of the charge system, in LSCO exhibits a peculiar behavior which points towards correlation effects. In terms of hopping models, $B(Ω)$ is directly related to an energy scale $t_T$, smaller by one order of magnitude than the full bandwidth $t_0 \sim W_0$.

description: It is becoming more critical that companies pursue exploration and exploitation activities at the same time to survive in times of past pace changes. To successfully achieve the goals of competing in the mature business excelling at efficiency and continuous improvement and in new markets with disruptive products and services, the companies must behave as an ambidextrous organization. In todays market conditions, companies that miss the opportunity to transform or fail to answer to a disruptive innovation rapidly find themselves in danger to continue the business. The analysis from researches of different firms that have succeeded as ambidextrous organizations have permitted to define six pillars that organizations must consider to change to achieve a high level of ambidexterity. This master thesis aims to determine the gap that exists between the research suggestions and the reality at a selected company. Moreover, the paper describes the consequences of such misalignment. To assess the gap, an empirical study conducted with employees of a tobacco company, which is in the journey of business transformation and has two business units: the one dedicated to competing in the mature market and the other one dedicated to the development of new disruptive innovation. The assessment considers three out of the six pillars: Structure and governance, Leadership and culture, and People and Skills. The gap assessment has helped to determine the most critical points to focus because of threads they represent to achieve ambidexterity successfully. The paper draws on the discussion of the relationship between the two units and the unifying elements that make them convey as one organization. This thesis contributes to the discourse on structural ambidexterity. Provides a better understanding of the consequences of the misalignment between literature and reality. Moreover, based on the gap found, the challenges and the relationship of the two units, questions if structural ambidexterity is the right approach for a company in the journey of transformation with the vision of cannibalizing with the new business the mature one.

description: A symmetric subset of the reals is one that remains invariant under some reflection z --> c-z. We consider, for any 0 < x <= 1, the largest real number D(x) such that every subset of $[0,1]$ with measure greater than x contains a symmetric subset with measure D(x). In this paper we establish upper and lower bounds for D(x) of the same order of magnitude: for example, we prove that D(x) = 2x - 1 for 11/16 <= x <= 1 and that 0.59 x^2 < D(x) < 0.8 x^2 for 0 < x <= 11/16. This continuous problem is intimately connected with a corresponding discrete problem. A set S of integers is called a B*[g] set if for any given m there are at most g ordered pairs (s_1,s_2) \in S \times S with s_1+s_2 = m; in the case g=2, these are better known as Sidon sets. Our lower bound on D(x) implies that every B*[g] set contained in \{1,2,...,n\} has cardinality less than 1.30036 \sqrt{gn}. This improves a result of Green for g >= 30. Conversely, we use a probabilistic construction of B*[g] sets to establish an upper bound on D(x) for small x.

description: Optical control of structural and electronic properties of Weyl semimetals allows development of switchable and dissipationless topological devices at the ultrafast scale. An unexpected orbitial-selective photoexcitation in type-II Weyl material WTe2 is reported under linearly polarized light (LPL), inducing striking transitions among several topologically-distinct phases. The symmetry features of atomic orbitals comprising the Weyl bands result in asymmetric electronic transitions near the Weyl points, and in turn an anisotropic response of interlayer shear motion with respect to linear light polarization, when a near-infrared laser pulse is applied. Consequently, not only annihilation of Weyl quasiparticle pairs, but also increasing separation of Weyl points can be achieved, complementing existing experimental observations. Our results provide a new perspective on manipulating the singularity of Weyl nodes and coherent control of electron and lattice quantum dynamics simultaneously.

description: This paper analyses the production costs and income of eight groups of farms: five private farms and three belonging to the Andean rural community. These farms are located in Peru and Bolivia and breed alpacas and llama for both meat and fibre. The research is based on case studies. Each case study includes several farms, grouped according to similar characteristics: available resources; breeding techniques and geographical location. A farm economic data analysis was undertaken by determining economic budget income. Statistics and data from 2003 were analysed to determine farm resources and farm production costs, per animal head and net farm income per labour unit and livestock head. This paper is relevant as regards economic data for production systems which are more often analysed for sociological and cultural aspects and less often for economic data and identification of real productive economic data which are not generally market driven.
What is going to change in EU rural development policies after 2013? Main implications in different national contexts

description: This paper will address the changes the CAP post‐2013 may bring to its second pillar in EU countries. After the presentation of the legislative package put forward by the European Commission, a debate emerged in some countries on how to define rural development strategies for the period 2014‐2020. The paper will discuss positive innovations and main challenges of the new rural development policies with respect to what happened in the 2007‐2013 period. In particular, the paper intends to focus on the following issues: 1) which relevant changes have been introduced in the rural development framework; 2) how these changes can influence the preparation of the next programming period 2014-2020, looking more in depth at three countries (Italy, Spain and France); 3) what lessons can be drawn from this reform and the initial implementation in three countries in terms of institutional changes and their likely success and failure. This analysis concludes that the success or failure of the 2014-2020 reform of rural development will significantly depend on what types of transaction costs and incentive systems will be brought about within the programming system. These two factors in turn will strongly depend on the way the different actors will perceive the different costs and incentives, their expectations on the role of rural development programmes in a context where budget for agriculture is shrinking everywhere, and finally their capability to build new strategic alliances and cooperation at every level (national, regional and local) with other economic and social actors. Future policy scenarios might bring new and heavy constraints to rural development policies and consequently might also reduce the opportunities of institutional innovations.

description: Using the partially completed Submillimeter Array with five antennas, we have observed the CO J=2-1 and 3-2 emission from the envelope surrounding the carbon star V Hya. The high-angular resolution (2"-4") maps show that V Hya is powering a bipolar molecular jet having an extreme velocity of 70-185 km/s. The axis of this high velocity jet is perpendicular to the major axis of the flattened disk-like envelope, which is expanding with a velocity of ~16 km/s.There is a third kinematic component, a medium-velocity wind having a deprojected velocity of 40-120 km/s moving along the disk plane. Both the high velocity jet and the medium velocity wind have a dynamical time scale of a few hundred years. The flattened structure and the collimated jet observed in V Hya suggests that the formation of asymmetrical structure proceeds while the central star is still in the AGB phase

The eccentricity enhancement effect of intermediate-mass-ratio-inspirals: dark matter and black hole mass

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: It was found that the dark matter (DM) in the intermediate-mass-ratio-inspiral (IMRI) system has a significant enhancement effect on the orbital eccentricity of the stellar massive compact object, such as a black hole (BH), which may be tested by space-based gravitational wave (GW) detectors including LISA, Taiji and Tianqin in future observations \citep{2019PhRvD.100d3013Y}. In this paper, we will study the enhancement effect of the eccentricity for an IMRI under different DM density profiles and center BH masses. Our results are as follows: $(1)$ in terms of the general DM spike distribution, the enhancement of the eccentricity is basically consistent with the power-law profile, which indicates that it is reasonable to adopt the power-law profile; $(2)$ in the presence of DM spike, the different masses of the center BH will affect the eccentricity, which provides a new way for us to detect the BH's mass; $(3)$ considering the change of the eccentricity in the presence and absence of DM spike, we find that it is possible to distinguish DM models by measuring the eccentricity at the scale of about $10^{5} GM/c^{2}$.

Bei diesem neuen Konzept werden natürliche L-Aminosäuren als chirale Quelle mit atropisomeren flexiblen Phosphorsäuren kombiniert, um ein chirales Salz zu bilden, das als Organokatalysator verwendet wird. Nachdem das Konzept der Gegenion-dirigierenden Katalyse nachgewiesen wurde, wurden unterschiedliche Parameter, wie die Wahl des Lösungsmittels, die Optimierung der Katalysator-Komponenten sowie wie der Reaktionsbedingungen, untersucht. Im letzten Schritt wurden unterschiedliche Cyclohexenone mit dem besten Katalysator und den idealen Reaktionsbedingungen reduziert. Es wurde gezeigt, dass hohe Enantioselektivitäten und Ausbeuten für eine Vielzahl von verschiedenen Substraten mit dem neuen Katalysatorsystem erreicht werden können.
description: The thesis in hand is dedicated to the asymmetric transfer hydrogenation of ,-unsaturated ketones via counteranion enhanced catalysis. This novel approach involves natural L-amino acids as main source of chirality in combination with atropisomeric flexible phosphoric acids in order to generate a chiral ion paired salt as an organocatalyst. After proving the concept of counteranion enhanced catalysis, several parameters including the solvent, catalyst components and reaction conditions were screened to identify optimum conditions. Once the ideal catalyst and conditions for the asymmetric transfer hydrogenations of enones were found the pool of starting materials was widened to include several 3-substituted cyclohexenones. High enantioselectivities and yields could be achieved for a wide range of substrates with the new catalytic systems, thereby proving the versatility of the newly developed concept of counteranion enhanced catalysis.

description: Dense plasmas occur in stars, giant planets and in inertial fusion experiments. Accurate modeling of the electronic structure of these plasmas allows for prediction of material properties that can in turn be used to simulate these astrophysical objects and terrestrial experiments. But modeling them remains a challenge. Here we explore the Korringa-Kohn-Rostoker Green's function (KKR-GF) method for this purpose. We find that it is able to predict equation of state in good agreement with other state of the art methods, where they are accurate and viable. In addition, it is shown that the computational cost does not significantly change with temperature, in contrast with other approaches. Moreover, the method does not use pseudopotentials - core states are calculated self consistently. We conclude that KKR-GF is a very promising method for dense plasma simulation.
Frozen light in periodic stacks of anisotropic layers

description: We consider a plane electromagnetic wave incident on a periodic stack of dielectric layers. One of the alternating layers has an anisotropic refractive index with an oblique orientation of the principal axis relative to the normal to the layers. It was shown recently (A. Figotin and I. Vitebskiy, Phys. Rev. E68, 036609 2003) that an obliquely incident light, upon entering such a periodic stack, can be converted into an abnormal axially frozen mode with drastically enhanced amplitude and zero normal component of the group velocity. The stack reflectivity at this point can be very low, implying nearly total conversion of the incident light into the frozen mode with huge energy density, compared to that of the incident light. Supposedly, the frozen mode regime requires strong birefringence in the anisotropic layers - by an order of magnitude stronger than that available in common anisotropic dielectric materials. In this paper we show how to overcome the above problem by exploiting higher frequency bands of the photonic spectrum. We prove that a robust frozen mode regime at optical wavelengths can be realized in stacks composed of common anisotropic materials, such as YVO₄, LiNb, CaCO₃, and the like.

Portals, practitioners, and public knowledge : a socio-technical analysis of digital teacher education
Creators: name: Korteweg, Lisa Maria
Publisher: name: University of British Columbia
Year: 2009

description: This study of professional development portals developed by the UBC research consortium, the Public Knowledge Project, analyzes the research, design and implementation of these PD portals from a social as well as technological perspective. The PKP teacher education portals are examined as socio-technical systems: networks of technology, information artifacts, and people and practices interacting with the larger world of teacher education, professional knowledge practices, and educational technologies. For a teacher education portal to be accessible and usable, the users, the knowledge documents, the portal infrastructure, and the social context must be in a continuous process of enrollment and translation, aligning each other into chains of association, moving towards the goal of stabilization or realizing the portal's network. The thesis asks how we can move towards a socio-technical analysis of professional development portals in order to stave off a techno-determinist evaluation of technological artifacts that result in accounts of either doomsday failure or hypothetical success. I turn instead to an analysis of how two PKP portals made empirical differences in practitioners' professional lives and their knowledge practices, and what studying portals might tell us about information, knowledge, and social processes in teacher education. The chapters, using both empirical and analytical methods, examine the social impact of the PKP portals and the web of social and material relations in which the portals were embedded; two social worlds of teaching -pre-service and in-service- where both groups were grappling with the issues of knowledge and computer practices flooding into teaching via the Internet.

description: Most of the novel superconductors are uniaxial crystals, with metallic planes ($ab$) orthogonal to an insulating axis ($c$). Far-infrared measurements of the reflectivity $R_{ab} (ω)$ provide valuable information on their low-energy electrodynamics, but involve delicate experimental issues. Two of them are a possible contamination of $R_{ab} (ω)$ from the c axis and the extrapolation of the $R_{ab}$ data to $ω$ =0, both above and below $T_c$. Here we discuss quantitatively these issues with particular regard to La$_{2-x}$Sr$_x$CuO$_{4+y}$, one of the most studied high-$T_c$ materials.

description: Abstract argumentation frameworks, as proposed by Dung in 1995, constitute one of the most widely used formalisms to model argumentation processes in the field of artificial intelligence. An abstract argumentation framework models an argumentation process as a directed graph, representing arguments as vertices and attacks between those arguments as directed arcs between the respective vertices. Furthermore, the coherent sets of arguments that are jointly acceptable under a given semantics, satisfying certain properties, are commonly called extensions. We consider two generalizations of such abstract argumentation frameworks. The first generalization that we consider, abstract argumentation frameworks with collective attacks, allows for attacks to be between sets of arguments and arguments, enabling a natural way of modeling that a set of arguments might defeat another argument if considered together which, in general, is not the case if viewed individually. Furthermore, the second considered generalization, claim augmented abstract argumentation frameworks, introduces the augmentation of arguments using claims. Such augmented frameworks allow for an intuitive way of expressing the extensions in terms of claims, that might be shared across multiple arguments, relaxing the abstraction to some extent. We provide complexity results for these two generalizations. To this end, we consider five common decision problems as well as various semantics for both types of argumentation frameworks and locate their position on the polynomial hierarchy. Furthermore, we make use of the well-established formalism of answer-set programming and give encodings for the various semantics, considering multiple approaches where applicable, to efficiently compute the extensions of such argumentation frameworks. Finally, we conduct experiments to compare the performance of our encodings. We present the results and the acquired data and discuss our findings and the drawn conclusions.

description: Unbiased CLTR requires click propensities to compensate for the difference between user clicks and true relevance of search results via IPS. Current propensity estimation methods assume that user click behavior follows the PBM and estimate click propensities based on this assumption. However, in reality, user clicks often follow the CM, where users scan search results from top to bottom and where each next click depends on the previous one. In this cascade scenario, PBM-based estimates of propensities are not accurate, which, in turn, hurts CLTR performance. In this paper, we propose a propensity estimation method for the cascade scenario, called CM-IPS. We show that CM-IPS keeps CLTR performance close to the full-information performance in case the user clicks follow the CM, while PBM-based CLTR has a significant gap towards the full-information. The opposite is true if the user clicks follow PBM instead of the CM. Finally, we suggest a way to select between CM- and PBM-based propensity estimation methods based on historical user clicks.

description: Aerosols are common in the atmospheres of exoplanets across a wide swath of temperatures, masses, and ages. These aerosols strongly impact observations of transmitted, reflected, and emitted light from exoplanets, obfuscating our understanding of exoplanet thermal structure and composition. Knowing the dominant aerosol composition would facilitate interpretations of exoplanet observations and theoretical understanding of their atmospheres. A variety of compositions have been proposed, including metal oxides and sulphides, iron, chromium, sulphur, and hydrocarbons. However, the relative contributions of these species to exoplanet aerosol opacity is unknown. Here we show that the aerosol composition of giant exoplanets observed in transmission is dominated by silicates and hydrocarbons. By constraining an aerosol microphysics model with trends in giant exoplanet transmission spectra, we find that silicates dominate aerosol opacity above planetary equilibrium temperatures of 950 K due to low nucleation energy barriers and high elemental abundances, while hydrocarbon aerosols dominate below 950 K due to an increase in methane abundance. Our results are robust to variations in planet gravity and atmospheric metallicity within the range of most giant transiting exoplanets. We predict that spectral signatures of condensed silicates in the mid-infrared are most prominent for hot (>1600 K), low-gravity (<10 m s$^{-2}$) objects.

description: Layered systems of commonly available fabric materials can be used by the public and healthcare providers in face masks to reduce the risk of inhaling viruses with protection about equivalent or better than the filtration and adsorption offered by 5-layer N95 respirators. Over 70 different common fabric combinations and masks were evaluated under steady state, forced convection air flux with pulsed aerosols that simulate forceful respiration. The aerosols contain fluorescent virus-like nanoparticles to track transmission through materials that greatly assist the accuracy of detection, thus avoiding artifacts including pore flooding and the loss of aerosol due to evaporation and droplet break-up. Effective materials comprise both absorbent, hydrophilic layers and barrier, hydrophobic layers. Although the hydrophobic layers can adhere virus-like nanoparticles, they may also repel droplets from adjacent absorbent layers and prevent wicking transport across the fabric system. Effective designs are noted with absorbent layers comprising terry cloth towel, quilting cotton and flannel. Effective designs are noted with barrier layers comprising non-woven polypropylene, polyester and polyaramid.

description: We report the observation and systematic investigation of the space charge effect and mirror charge effect in photoemission spectroscopy. When pulsed light is incident on a sample, the photoemitted electrons experience energy redistribution after escaping from the surface because of the Coulomb interaction between them (space charge effect) and between photoemitted electrons and the distribution of mirror charges in the sample (mirror charge effect). These combined Coulomb interaction effects give rise to an energy shift and a broadening which can be on the order of 10 meV for a typical third-generation synchrotron light source. This value is comparable to many fundamental physical parameters actively studied by photoemission spectroscopy and should be taken seriously in interpreting photoemission data and in designing next generation experiments.

Are Corn and Soybean Trend Yields Changing in Illinois?

description: Crop yields are influenced by a complex combination of factors, including weather, seed genetics, soil quality, and production management. Regardless, yields still tend to show a general trend over time, which is referred to as the “trend yield.” There has been much debate over whether improved technology has caused trend yields to change in recent years. Many experts believe recent corn yield increases were caused by advancements in biotechnology for seed genetics. It has been suggested that a lack of research on soybean genetics has led to a plateau in the soybean trend yield. It has been widely accepted that these new trends began in the mid-1990s and that they should be used for estimating future yields. However, weather should be taken into consideration because it can have a large effect on trend yields. The purpose of this paper is to examine whether trend yields in Illinois for corn and soybeans have changed since the mid-1990s. The effect of both weather and technology on yields in Illinois is estimated over the period 1960-2008. The results of this research provide evidence that weather plays a significant and important role in determining yields.

description: Considering coupling to a micro-structured bath as a relaxation mechanism in a periodically driven dissipative Haldane model, we establish that the system may be tuned to a stroboscopic topological steady state at all finite temperatures. The amplitude and frequency of the periodic drive is so chosen that the Floquet Hamiltonian describing the Haldane model at stroboscopic instants of time in the unitary situation is topologically non-trivial. We establish that in the stroboscopic steady state, the system reaches a thermal state of the Floquet Hamiltonian at a controlled temperature. Further, it is observed that even with a coupling to a quasi-local bath, remarkably a Chern insulator can indeed be prepared in a Chern non-trivial pure steady state which is expected to exhibit a stroboscopic bulk-boundary correspondence. Using the non-uniqueness of the macroscopic bulk electric polarisation of a Chern insulator in its topological phase, we propose a generalised Chern invariant that reflects the topology of out-of-equilibrium many-body stroboscopic states of the Haldane model even in a dissipative ambience. The generalised topology of dynamical Chern insulators being dependent on single-particle correlations, is expected to manifest in experiments probing many-body quantum observables.
