Magnetic Strings in Dilaton Gravity

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: First, I present two new classes of magnetic rotating solutions in four-dimensional Einstein-Maxwell-dilaton gravity with Liouville-type potential. The first class of solutions yields a 4-dimensional spacetime with a longitudinal magnetic field generated by a static or spinning magnetic string. I find that these solutions have no curvature singularity and no horizons, but have a conic geometry. In these spacetimes, when the rotation parameter does not vanish, there exists an electric field, and therefore the spinning string has a net electric charge which is proportional to the rotation parameter. The second class of solutions yields a spacetime with an angular magnetic field. These solutions have no curvature singularity, no horizon, and no conical singularity. The net electric charge of the strings in these spacetimes is proportional to their velocities. Second, I obtain the ($n+1$)-dimensional rotating solutions in Einstein-dilaton gravity with Liouville-type potential. I argue that these solutions can present horizonless spacetimes with conic singularity, if one chooses the parameters of the solutions suitable. I also use the counterterm method and compute the conserved quantities of these spacetimes.

description: We calculate the quasiparticle properties of $\rm{MoS_2}$ monolayer at $T=0$ considering the dynamical electron-electron interaction effect within random-phase-approximation (RPA). The calculations are carried out for an electron-doped slab of $\rm{MoS_2}$ monolayer using a minimal massive Dirac Hamiltonian and the quasi-two-dimensional nature of the Coulomb interaction in this system is taken into account considering a modified interaction of Keldysh type. Having calculated the real and imaginary parts of the retarded self-energy, we find the spectral function and discuss the impact of extrinsic variables such as the dielectric medium and the charge carrier density on the appearance and position of the quasiparticle peaks. We also report the results of the renormalization constant and the effective Fermi velocity calculations in a broad range of the coupling constant and carrier density. We show that the effective Fermi velocity obtained solving the self-consistent Dyson equation has an absolutely different behavior from the one found from the on-shell approximation. Our results show that the nonlocal dielectric screening of the monolayer tends to stabilize the Fermi liquid picture in $\rm{MoS_2}$ monolayer and that the interaction strength parameter of this system is a multivariable function of the coupling constant, carrier density, and also the screening length.

Melanosuchus

description: Melanosuchus and its prolific debates
 Melanosuchus was originally proposed by Gray (1862) as a monospecific genus to relocate the species Caiman niger described by Spix (1825). For a synonym list of Melanosuchus niger see Medem (1963). Regarding the phylogenetic relationships of the genus there are two main propositions: 1) nested within Caiman genus, frequently as sister of C. latirostris (e.g., Poe 1996; Brochu 1997, 1999; Souza-Filho et al. 2019); or, 2) as sister species of Caiman genus (e.g., Oaks 2011; Roberto et al. 2020). The validity of the Melanosuchus is still an open debate with some authors suggesting its synonymization with Caiman (Poe 1996), this discussion, for now, goes beyond the scope of the present contribution. However, we suggest that the propositions made by Fitzhugh (2016) for molecular inferences should be considered in future works addressing this question.

description: This study evaluates the impact of food security program – an almost universal program of Indonesian Social Safety Net Program in the time of economic crisis. Food security program aimed to protect poor households from the negative effects of economic crisis by means of highly subsidized rice. To assess the impact of the program, this study utilizes matching estimator approach combined with difference in difference method. The rich longitudinal dataset used in this study enables matching estimator and difference in difference approach to provide accurate estimate of the program’s impact on its beneficiaries. Results indicate the positive impact of the food security program on the expenditures of richer nutrient food which include meat, fish and dairy products. The program has also substantial impact on health expenditure. In addition, this study finds fly-paper effects where food security program has increased rice and staple food expenditures in the short period. Aid-fungibility is also evident since the program has positive effect on adult goods expenditure. The implication is that improved targeting or applying conditionality might mitigate the unintended effects resulting from the program.

description: In den letzten Jahren hat die digitale Transformation die Musikindustrie gravierend verändert und zur wachsenden Beliebtheit des Musik Streamings beigetragen. Die vielen Daten, die dabei entstehen, können verwendet werden, um unentdeckte Verhaltensmuster und andere Einblicke in das Musikgeschäft zu gewinnen. In dieser Masterarbeit werden soziodemographische Faktoren untersucht, ob sie für den Erfolg eines Liedes förderlich sind. Zu diesem Zweck werden Daten der Musikstreamingplattform Spotify für mehrere Lieder aufbereitet und aggregiert. Die resultierenden Längsschnittdaten werden im Rahmen einer Regression verwendet, um die relative Änderung der wöchentlichen Anzahl an Wiedergaben zu beschreiben. Neben Linearen Regressionsmodellen werden mehrere Formen Linearer Gemischter Modelle auf diese Problemstellung angewandt und anhand ihrer Vorhersagekraft auf einem Testdatensatz verglichen. Basierend auf diesem Vergleich wird ein finales Modell ausgewählt, welches detaillierter untersucht wird. Diese Analyse und Interpretation identifiziert wichtige Segmente des Publikums, die einen Einfluss auf den Erfolg eines Liedes haben.
description: In recent years, the digital transformation of the music industry led to a rapid increase in online music streaming. As a consequence, plenty of data is generated which can be examined for undetected patterns and further insights into the music business. Within this thesis socio-demographic factors are investigated whether they drive the successful development of a song. Data of several songs and streaming events on Spotify is prepared and aggregated for this purpose. The resulting longitudinal data is used in a regression context to describe the relative change in a song's weekly number of streams. Besides Linear Regression Models, Linear Mixed Models in various forms are applied on the given problem. A final model is chosen by comparing the models' prediction performance on a separate test dataset. The concluding analysis and interpretation of this model unveils important segments of the target audience which have an impact on the success of a song.

description: In diesem Beitrag wird nach Wegen gesucht, die nichtmarktlichen Leistungen der Schweizer Landwirtschaft gezielter als bislang in die Landwirtschaftliche Gesamtrechnung zu integrieren. Dabei werden drei Methoden geprüft: Die Erfassung der leistungsbezogenen Direktzahlungen, die Ermittlung der zusätzlichen Kosten und Zahlungsbereitschaftsanalysen. Während gegen die Verwendung von Zahlungsbereitschaftsanalysen insbesondere unter Berücksichtigung der Datenlage in der Schweiz grundsätzliche Bedenken geäussert werden, gelangt die Arbeit zum Ergebnis, dass die Nicht-Markt-Leistungen einen Wert in der Grössenordnung von 0,8 bis 1,3 Milliarden Franken haben. Damit gibt es einen positiven, aber moderaten Beitrag der Landwirtschaft zur volkswirtschaftlichen Wertschöpfung. Klar formulierte und demokratisch legitimierte Ziel-Mittel-Kataloge bei der Bereitstellung nichtmarktlicher Leistungen würden den Bewertungsprozess methodisch erleichtern.

description: Incompressible Magnetohydrodynamics is often assumed to describe solar wind turbulence. We use extended self similarity to reveal scaling in structure functions of density fluctuations in the solar wind. Obtained scaling is then compared with that found in the inertial range of quantities identified as passive scalars in other turbulent systems. We find that these are not coincident. This implies that either solar wind turbulence is compressible, or that straightforward comparison of structure functions does not adequately capture its inertial range properties.

description: Inside a three-dimensional strong topological insulator, a tube with $h/2e$ magnetic flux carries a pair of protected one-dimensional linear fermionic modes. This phenomenon is known as the "wormhole effect". In this work, we find that the "wormhole effect", as a unique degree of freedom, introduces exotic transport phenomena and thus manipulates the transport properties of topological insulators. Our numerical results demonstrate that the transport properties of a double-wormhole system can be manipulated by the wormhole interference. Specifically, the conductance and local density of states both oscillate with the Fermi energy due to the interference between the wormholes. Furthermore, by studying the multi-wormhole systems, we find that the number of wormholes can also modulate the differential conductance through a $\mathbb{Z}$$_{2}$ mechanism. Finally, we propose two types of topological devices in real applications, the "wormhole switch" device and the "traversable wormhole" device, which can be finely tuned by controlling the wormhole degree of freedom.

Active matter: quantifying the departure from equilibrium

description: Active matter systems are driven out of equilibrium at the level of individual constituents. One widely studied class are systems of athermal particles that move under the combined influence of interparticle interactions and self-propulsions, with the latter evolving according to the Ornstein-Uhlenbeck stochastic process. Intuitively, these so-called active Ornstein-Uhlenbeck particles (AOUPs) systems are farther from equilibrium for longer self-propulsion persistence times. Quantitatively, this is confirmed by the increasing equal-time velocity correlations (which are trivial in equilibrium) and by the increasing violation of the Einstein relation between the self-diffusion and mobility coefficients. In contrast, the entropy production rate, calculated from the ratio of the probabilities of the position space trajectory and its time-reversed counterpart, has a non-monotonic dependence on the persistence time. Thus, it does not properly quantify the departure of AOUPs systems from equilibrium.

Ab initio study of the electronic structure of Co adatom on Cu(111) surface
Creators: name: Hossain, Arefa
Publisher: name: University of British Columbia
Year: 2009

description: We present the ab initio Density Functional study of the electronic structure of Co adatoms on Cu (111) surface. A number of Scanning Tunneling Spectroscopy (STS) experiments performed on the systems which contain magnetic adatoms on the noble metal surfaces (e.g., Co, Ce on Cu, Ag, Au (111) planes) [1, 6, 7] report the observation of intriguing resonances at the Fermi energy. However, the interpretation of these experiments in terms of the Kondo physics is not totally conclusive and gave rise to many questions that are still to be answered. The first step towards understanding the meaning of these experiments is to understand the electronic structure of such systems. The so called supercell approximation is used to simulate a Cu slab consisting of Cu (111) planes. The electronic properties of Co adatom on Cu (111) surface is studied in a symmetric 2 x 2 supercell in the xy directions with fifteen Cu (111) and two Co planes in the z direction. It is observed that Co is in the d⁸ high spin state with the magnetic moment of 1.7 μB per Co atom. The width of Co d DOS is a result of the coupling with the Cu sp surface and bulk states. At least the first three Cu layers of the bulk Cu slab have significant influence on the electronic properties of Co.

description: Exotic baryons have been predicted in the context of the chiral soliton model. These states have been identified with strangeness +1 resonances reported in a number of experiments. In this talk it is pointed out that the technique used to quantize these solitons in most conventional treatments depends on dynamical assumptions beyond those in standard large Nc physics. These additional assumptions have never been justified.

description: Der Agrarstrukturwandel ist mit Anpassungsprozessen verbunden, die oftmals mit größten-teils fremdfinanzierten Investitionen einhergehen. Eine Folge davon sind sinkende Eigenkapi-talquoten in landwirtschaftlichen Betrieben. Somit ist zu erwarten, dass die Bedeutung der finanziellen Flexibilität - verstanden als finanzieller Spielraum eines Betriebs - in der Land-wirtschaft in Zukunft zunehmen wird. Es stellt sich die Frage, inwieweit Entscheider schon jetzt die finanzielle Flexibilität bei Investitionsentscheidungen berücksichtigen. Der vorlie-gende Beitrag untersucht experimentell die Rolle der finanziellen Flexibilität bei Investitions-entscheidungen. Dazu werden Studierenden der Agrarwissenschaften in einem Discrete Choi-ce Experiment hypothetische Investitionsalternativen zur Entscheidung vorgelegt. Die Investi-tionsalternativen unterscheiden sich dabei in ihrer Rentabilität, dem Risiko und ihrer Auswir-kung auf die finanzielle Flexibilität des Betriebs. Es zeigt sich, dass die Teilnehmer die finan-zielle Flexibilität bei ihren Investitionsentscheidungen berücksichtigen. Jeder dritte Teilneh-mer gibt an, dass die finanzielle Flexibilität gegenüber den Kriterien Rentabilität und Risiko sogar entscheidungsbestimmend ist. Auch kann für die finanzielle Flexibilität ein ökonomi-scher Wert, der signifikant von Null verschieden ist, quantifiziert werden. Bislang scheint der finanziellen Flexibilität also in der Investitionstheorie zu wenig Aufmerksamkeit zuteil ge-worden zu sein.

description: The sustainable use of natural resources became a top priority for countries of the world regardless of their level of development. While our current consumption pattern not only requires two planets Earth, the way it is organized makes it more of a burden. Economic growth, being a measure of success for most governments, has a strong link with resource use and, thus, environment degradation, which needs to be decoupled. Unsustainable production and consumption result in growing volumes of waste. The main goal of current research is to analyze whether Municipal Solid Waste (MSW) reform (WR) in Russia includes elements to promote circular practices like recycling, moving the country to another, sustainable level of development with a focus on resource efficiency and (circular) materials value preservation. The research was organized to analyze literature on concepts related to efficient use of resources, their role in a circular economy and waste management and, from the practical side, to analyze literature on waste management in Russia and recent changes in it associated with MSW reform. Analysis of the literature confirmed that the resources of the planet are scarce, and the globally agreed sustainable development path was chosen to decouple economic growth to meet the needs of the growing population to prevent environmental degradation and resource depletion. Circular Economy (CE) could be considered as a concept bringing the economic, social and environmental agenda together, proposing practical approaches to new models of resource use contributing to keeping the value of materials in the economy for longer. Whereas waste management on its own is only a narrow part of the economic cycle where resource management is limited to returning products and materials from the end of life to useful life through proper management and recycling techniques, it is still strongly associated with the CE paradigm. With its WR, Russia is reintroducing the recycling industry as a key element of MSW management which is capable of contributing to the emergence of a CE and its ultimate goal of prolonging material value preservation in the country. Although current WR in Russia is still at the initial stages, and its reality check shows deficiencies of organizational, financial and educational resources, using best practices from abroad together with local experience represent a good starting point. Still, momentum to build a strong foundation for CE in the country starting from MSW recycling industry is lacking clear linkages and understanding at all levels of government.

description: We theoretically investigate the effects of the lattice geometry on the nonequilibrium dynamics of photo-excited carriers in a half-filled two-dimensional Hubbard model. Using a nonequilibrium generalization of the dynamical cluster approximation, we compare the relaxation dynamics in lattices which interpolate between the triangular lattice and square lattice configuration and thus reveal the role of the geometric frustration in these strongly correlated nonequilibrium systems. In particular, we show that the cooling effect resulting from the disordering of the spin background is less effective in the triangular case because of the frustration. This manifests itself in a longer relaxation time of the photo-doped population, as measured by the time-resolved photo-emission signal, and a higher effective temperature of the photo-doped carriers in the non-thermal steady state after the intra-Hubbard-band thermalization.

description: In this work we study the contribution of the isoscalar tensor coupling to the realization of pseudospin symmetry in nuclei. Using realistic values for the tensor coupling strength, we show that this coupling reduces noticeably the pseudospin splittings, especially for single-particle levels near the Fermi surface. By using an energy decomposition of the pseudospin energy splittings, we show that the changes in these splittings come by mainly through the changes induced in the lower radial wave function for the low-lying pseudospin partners, and by changes in the expectation value of the pseudospin-orbit coupling term for surface partners. This allows us to confirm the conclusion already reached in previous studies, namely that the pseudospin symmetry in nuclei is of a dynamical nature.

Each of these items must follow the Standard Operating Procedures (SOP) of an organization, such as recording, sorting, reviewing, drafting, distributing, and so on. All activities must be controlled by an officer to promote the efficiency of the task. Therefore, compliance with SOPs is very important in all types of services including graphic design. So, this study focuses on the quality of CMNGCSB graphic designers when order recording is done. Besides, this study was also conducted to improve the quality of service when recording the latest, effective, and customer-friendly orders in the SOP. This study uses a quantitative survey method through a questionnaire distributed to 40 respondents among CMNGCSB staff who are the main customers of CMNGCSB Graphic Design Unit, who were randomly selected to answer the questionnaire. The findings of this study show, the Google Forms application method in the SOP record bookings, has a positive impact on the customer evaluation of CMNGCSB graphic design services. The results show that its application should be continued to improve the efficiency of order recording, thus boosting the company's graphic design services.

description: Influences of a substrate below samples in imaging performances are studied by reaching the solution to the dyadic Green's function, where the substrate is modeled as half space in the sample region. Then, theoretical and numerical analysis are performed in terms of magnification, depth of field, and resolution. Various settings including positions of dipoles, the distance of the substrate to the focal plane and dipole polarization are considered. Methods to measure the resolution of $z$-polarized dipoles are also presented since the modified Rayleigh limit cannot be applied directly. The silicon substrate and the glass substrate are studied with a water immersion objective lens. The high contrast between silicon and water leads to significant disturbances on imaging.
An experimental investigation of a spherical reflector antenna for operation in rain at millimeter wavelengths
Creators: name: Street, Timothy William
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is an extensive investigation of an innovative spherical reflector antenna design for operation at millimetre wavelengths in rain. Radiation pattern measurements were performed at three elevation angles (10°, 30°, 50°) and three frequencies (27.5 GHz, 31.5 GHz, 35 GHz). Wet-antenna attenuation measurements were also performed at three reflector angles (20°, 30°, 40°), and at the three frequencies mentioned above. The antenna investigated consists of a 30 cm diameter shallow spherical reflector with a relatively large ratio of focal length to diameter. The reflector is illuminated by a pyramidal feed horn which is fixed in a downward facing position, while the reflector swivels in the vertical plane to accommodate the direction of incident radiation. The antenna's performance was compared to that of a conventional parabolic reflector antenna under both dry and wet conditions with favourable results. Beamwidth values varied approximately between 1° and 3° and sidelobe levels varied approximately between -12 dB and -20 dB depending on the frequency and elevation angle. Under wet conditions the antenna performed quite well with a maximum observed attenuation level of 1.6 dB at the worst reflector angle used; while conventional reflector antennas experience attenuation levels of up to 10 dB. Cross-polarization discrimination of the dry antenna was also found to be approximately 34 dB.

description: In this work we focus on multi-turn passage retrieval as a crucial component of conversational search. One of the key challenges in multi-turn passage retrieval comes from the fact that the current turn query is often underspecified due to zero anaphora, topic change, or topic return. Context from the conversational history can be used to arrive at a better expression of the current turn query, defined as the task of query resolution. In this paper, we model the query resolution task as a binary term classification problem: for each term appearing in the previous turns of the conversation decide whether to add it to the current turn query or not. We propose QuReTeC (Query Resolution by Term Classification), a neural query resolution model based on bidirectional transformers. We propose a distant supervision method to automatically generate training data by using query-passage relevance labels. Such labels are often readily available in a collection either as human annotations or inferred from user interactions. We show that QuReTeC outperforms state-of-the-art models, and furthermore, that our distant supervision method can be used to substantially reduce the amount of human-curated data required to train QuReTeC. We incorporate QuReTeC in a multi-turn, multi-stage passage retrieval architecture and demonstrate its effectiveness on the TREC CAsT dataset.

We illustrate the method by deriving new simple relations between the functions Xsi_3(w) and Lambdabar Xsi(w) and the sums Sum_n DeltaE^(n)_j tau^(n)_j(1) tau^(n)_j(w) (j=1/2,3/2), that involve leading quantities, namely the Isgur-Wise functions tau^(n)_j(w) and the level spacings DeltaE^(n)_j. The simplicity of our results follows from the fact that, for the non-forward amplitude B(v_i)->D^(n)(v')->B(v_f), there are three variables (w_i,w_f,w_if)=(v_i.v',v_f.v',v_i.v_f) independent in a certain domain, and we consider the zero recoil frontier (w,1,w) where only a finite number of j^P states contribute (1/2^+,3/2^+). These sum rules reduce to known results at w=1, for Lambdabar obtainted by Voloshin, and for Xsi_3(1) obtained by Le Yaouanc et al. and by Uraltsev, and generalizes them to all values of w. We discuss phenomenological applications of these results, in particular the check of Bakamjian-Thomas quark models and the comparison with the QCD Sum Rules approach.

description: Im Lebensmitteleinzelhandel besitzt die Verkaufsförderung bereits alltäglichen Charakter. Jede Woche werden in Deutschland für eine breite Palette an Produkten verschiedene Verkaufsförderungsmaßnahmen, z. B. Sonderangebote oder Rabatte, eingesetzt. Allerdings fehlen präzise Angaben über die wöchentlich eingesetzte Anzahl an Verkaufsförderungsaktionen und deren Preisreduzierungen, weswegen die Handzettel von 13 bedeutenden Geschäften des Lebensmitteleinzelhandels analysiert wurden. Es hat sich gezeigt, dass die großen Verbrauchermärkte durchschnittlich die meisten Verkaufsförderungsaktionen durchführen sowie die höchsten Preisreduzierungen offerieren, gefolgt von den Discountern und den kleinen Verbrauchermärkten. Vor den Feiertagen steigt die Anzahl an Aktionen für alkoholische Getränke signifikant an, in der Woche des Muttertags wird signifikant mehr Schokolade in den Handzetteln aufgeführt. Die Warengruppen, in denen am häufigsten Aktionen durchgeführt werden, sind „Alkoholische Getränke“, „Fleisch/Geflügel“ und „Alkoholfreie Getränke“. Sonderangebote stellen weiterhin ein zentrales Verkaufsförderungsinstrument dar, das gesamte Spektrum an Instrumenten wird nur von drei Geschäften genutzt. Teilweise ist eine gewisse Koordination der Geschäfte bezüglich ihres Angebotsverhaltens zu erkennen.

description: The market for beer in Germany is special for many reasons, e.g. the purity law, the large number of breweries, or consumers who are highly loyal to local brands. To what extent brand loyalty affects spatial pricing strategies, is the main question of this article. We employ weekly retail scanner data for Germany from 2000 to 2001. We find that discounts are higher and offered more often the closer the brands are sold to the brewery they originate from. In addition, average prices are also lower on home markets. According to Anderson and Kumar (2007) this strategy is chosen because promotions generate new loyal customers who repay in periods of regular prices. Thus, loyalty of consumers may be endogenous. Alternatively, retailers use local beer brands as loss leaders, which can also explain the observed regional pricing strategies.

Gravitational radiation from rotating monopole-string systems

description: We study the gravitational radiation from a rotating monopole-antimonopole pair connected by a string. While at not too high frequencies the emitted gravitational spectrum is described asymptotically by $P_n\propto n^{-1}$, the spectrum is exponentially suppressed in the high-frequency limit, $P_n\propto \exp(-n/n_{\rm cr})$. Below $n_{\rm cr}$, the emitted spectrum of gravitational waves is very similar to the case of an oscillating monopole pair connected by a string, and we argue therefore that the spectrum found holds approximately for any moving monopole-string system. As application, we discuss the stochastic gravitational wave background generated by monopole-antimonopole pairs connected by strings in the early Universe and gravitational wave bursts emitted at present by monopole-string networks. We confirm that advanced gravitational wave detectors have the potential to detect a signal for string tensions as small as $Gμ\sim 10^{-13}$.

description: We assess the distributional effects of the transmission of world market price shocks for the highly import dependent economy of Israel. We combine a CGE simulation with an empirical cointegration analysis for assessing the direction and extent of the connectedness of Israeli and world market prices. The Israeli and the world market for wheat are found to be integrated. Price shocks are completely transmitted from the world market to the domestic Israeli market. We find negative effects on the amount of domestic household income, on consumption and on welfare. Regressive expenditure effects dominate progressive income effects so that the resulting domestic income distribution appears to be more unequal.
Ambipolar diffusion in the Bifrost code

description: Ambipolar diffusion is a physical mechanism related to the drift between charged and neutral particles in a partially ionized plasma that is key in many different astrophysical systems. However, understanding its effects is challenging due to basic uncertainties concerning relevant microphysical aspects and the strong constraints it imposes on the numerical modeling. Our aim is to introduce a numerical tool that allows us to address complex problems involving ambipolar diffusion in which, additionally, departures from ionization equilibrium are important or high resolution is needed. The primary application of this tool is for solar atmosphere calculations, but the methods and results presented here may also have a potential impact on other astrophysical systems. We have developed a new module for the stellar atmosphere Bifrost code that improves its computational capabilities of the ambipolar diffusion term in the Generalized Ohm's Law. This module includes, among other things, collision terms adequate to processes in the coolest regions in the solar chromosphere. As a key feature of the module, we have implemented the Super Time-Stepping (STS) technique, that allows an important acceleration of the calculations. We have also introduced hyperdiffusion terms to guarantee the stability of the code. We show that to have an accurate value for the ambipolar diffusion coefficient in the solar atmosphere it is necessary to include as atomic elements in the equation of state not only hydrogen and helium but also the main electron donors like sodium, silicon and potassium. In addition, we establish a range of criteria to set up an automatic selection of the free parameters of the STS method that guarantees the best performance, optimizing the stability and speed for the ambipolar diffusion calculations. We validate the STS implementation by comparison with a self-similar analytical solution.

CALCULATING THE ‘GREENING’ EFFECT – A CASE STUDY APPROACH TO ESTIMATE THE GROSS MARGIN LOSSES IN DIFFERENT FARM TYPES IN GERMANY DUE TO THE REFORM OF THE CAP

description: The European Union’s Common Agricultural Policy is currently undergoing a reform process which inter alia aims to achieve a higher environmental standard in agricultural production by binding direct payments to practices beneficial for the climate and the environment (the so-called ‘greening’). Some experts as well as some farmers doubt the effectiveness of the proposed measures. I simulate how farms would respond to these measures using a case study farm modeling approach and data for different farm types in Germany. I find that the currently envisaged ‘greening’ measures can be expected to function in general due to the linkage to the direct payments, which provide a strong disincentive to forego participation. The individual economic outcome strongly depends on the current intensity of the farm in question and on the implementation details of the introduced measures. However, farms with very high gross margins per hectare will forego the support scheme.

description: The impact of severe plastic deformation by high-pressure torsion on the relaxation of the glassy and supercooled liquid states of Pd$_{40}$Ni$_{40}$P$_{20}$ was investigated using a combination of differential scanning calorimetry, low-temperature heat capacity and fluctuation electron microscopy. The changes in the calorimetric signals due to deformation and subsequent heat treatments were analyzed and a correlation between deformation (rejuvenation) and annealing (relaxation) was found in relation to medium-range order (MRO). Moreover, a coupling between the occurrence of an exothermic peak in the supercooled liquid state and specific changes in the MRO types were identified. These findings are comprehended in a potential energy landscape scheme offering a new approach for MRO engineering of glasses.
