Measurement of the Top Quark Mass with the Dynamical Likelihood Method using Lepton plus Jets Events with b-tags in ppbar Collisions at s**(1/2) = 1.96 TeV

description: This report describes a measurement of the top quark mass, M_{top}, with the dynamical likelihood method (DLM) using the CDF II detector at the Fermilab Tevatron. The Tevatron produces top/anti-top pairs in protons and anti-protons collisions at a center-of-mass energy of 1.96 TeV. The data sample used in this analysis was accumulated from March 2002 through August 2004, which corresponds to an integrated luminosity of 318 pb^{-1}. We use the top/anti-top candidates in the ``lepton+jets'' decay channel, requiring at least one jet identified as a b quark by finding a displaced secondary vertex. The DLM defines a likelihood for each event based on the differential cross section as a function of M_{top} per unit phase space volume of the final partons, multiplied by the transfer functions from jet to parton energies. The method takes into account all possible jet combinations in an event, and the likelihood is multiplied event by event to derive the top quark mass by the maximum likelihood method. Using 63 top quark candidates observed in the data, with 9.2 events expected from background, we measure the top quark mass to be 173.2 +2.6/-2.4 (stat.) +/- 3.2 (syst.) GeV/c^2, or 173.2 +4.1/-4.0 GeV/c^2.

description: In this article, we investigate the content distribution in the hotspot area, whose traffic is offloaded by the combination of the unmanned aerial vehicle (UAV) communication and edge caching. In cache-enabling UAV-assisted cellular networks, the network deployment and resource allocation are vital for quality of experience (QoE) of users with content distribution applications. We formulate a joint optimization problem of UAV deployment, caching placement and user association for maximizing QoE of users, which is evaluated by mean opinion score (MOS). To solve this challenging problem, we decompose the optimization problem into three sub-problems. Specifically, we propose a swap matching based UAV deployment algorithm, then obtain the near-optimal caching placement and user association by greedy algorithm and Lagrange dual, respectively. Finally, we propose a low complexity iterative algorithm for the joint UAV deployment, caching placement and user association optimization, which achieves good computational complexity-optimality tradeoff. Simulation results reveal that: i) the MOS of the proposed algorithm approaches that of the exhaustive search method and converges within several iterations; and ii) compared with the benchmark algorithms, the proposed algorithm achieves better performance in terms of MOS, content access delay and backhaul traffic offloading.

description: Due to the decrease in cost, size and weight, \acp{UAV} are becoming more and more popular for general-purpose civil and commercial applications. Provision of communication services to \acp{UAV} both for user data and control messaging by using off-the-shelf terrestrial cellular deployments introduces several technical challenges. In this paper, an approach to the air-to-ground channel characterization for low-height \acp{UAV} based on an extensive measurement campaign is proposed, giving special attention to the comparison of the results when a typical directional antenna for network deployments is used and when a quasi-omnidirectional one is considered. Channel characteristics like path loss, shadow fading, root mean square delay and Doppler frequency spreads and the K-factor are statistically characterized for different suburban scenarios.

description: Controversy over the use of genetically engineered (GE) crops may have induced some farmers to disadopt these seeds, making a traditional diffusion model inappropriate. In this study, we develop and estimate a dynamic diffusion model, examine the diffusion paths of GE corn, soybeans, and cotton, predict the adoption of those crops over the next two years, and explore the main determinants of the diffusion rate. Our estimates indicate that future growth of Bt crops will be slower or negative, depending mainly on the infestation levels of the target pests. Adoption of herbicide-tolerant soybeans and cotton will continue to increase, unless consumer sentiment in the United States changes radically.

description: Detailed control over the motion of colloidal particles is relevant in many applications in colloidal science such as lab-on-a-chip devices. Here, we use an external magnetic field to assemble paramagnetic colloidal spheres into colloidal rods of several lengths. The rods reside above a square magnetic pattern and are transported via modulation of the direction of the external magnetic field. The rods behave like bipeds walking above the pattern. Depending on their length, the bipeds perform topologically distinct classes of protected walks. We design parallel polydirectional modulation loops of the external field that command up to six classes of bipeds to walk on distinct predesigned paths. Using such loops, we induce the collision of reactant bipeds, their polymerization addition reaction to larger bipeds, the separation of product bipeds from the educts, the sorting of different product bipeds, and also the parallel writing of a word consisting of several letters. Our ideas and methodology might be transferred to other systems for which topological protection is at work.

description: We explore the dependence of the pT correlations in the event-by-event analysis of relativistic heavy-ion collisions at RHIC made recently by the PHENIX and STAR Collaborations. We point out that the observed scaling of strength of dynamical fluctuations with the inverse number of particles can be naturally explained by the formation of clusters. We argue that the large magnitude of the measured covariance implies that the clusters contain at least several particles. We also discuss whether the clusters may originate from jets. In addition, we provide numerical estimates of correlations coming from resonance decays and thermal clusters.

description: Selfishness of preferences alone will not support the coordination necessary for the industrialization of the food system. Social capital relationships of mutual sympathy (caring) yield socio-emotional goods that are important in the more personal business world of evolving incomplete contracts and alliances involving input suppliers, processors, and labor. Relationships are also critical when consumers are buying image as well as physical products. Management and policy alternatives constitute investment in social capital that can affect opportunism, risk, loyalty, and trust.
Optimal design of a bilayer for the highest thermal resistance: A lesson learned from the shells of snails from hydrothermal extreme environment

Subjects: subject: Applied Physics (physics.app-ph)

description: Inspired by the unique design of the shells of snails inhabiting the deep-sea hydrothermal environment, here we theoretically study the temperature response of a bilayer to an external thermal impulse. A semi-analytical solution to the temperature field in the bilayer is obtained, allowing us to assess the peak temperature that occurs on the inner wall as a quantitative indicator of the thermal resistance of the bilayer. The structural determining factors of the thermal resistance of a bilayer are then investigated by examining the effects of the stacking sequence and volume fractions of the constitutive layers on the peak temperature on the inner wall. Our results indicate that the stacking sequence of the two layers in a bilayer, as well as their volume fractions, play important roles in determining the thermal resistance. For two layers with given materials, there exists an optimal stacking sequence and thickness ratio giving rise to the best thermal resistance. The results of our work not only account for the unique laminated design of the snail shells from hydrothermal environments but also provide practical guidelines for the design of multilayer thermal barriers in engineering.

description: Motivated by recent experiments involving the non-destructive imaging of magnetization of a spin-1 87Rb Bose gas (Higbie et al., cond-mat/0502517), we address the question of how the spontaneous magnetization of a ferromagnetic BEC occurs in a spin-conserving system. Due to competition between the ferromagnetic interaction and the total spin conservation, various spin structures such as staggered magnetic domains, and helical and concentric ring structures are formed, depending on the geometry of the trapping potential.

description: A system of replicators with Hebbian random couplings is studied using dynamical methods. The self-reproducing species are here characterized by a set of binary traits and interact based on complementarity. In the case of an extensive number of traits we use path-integral techniques to demonstrate how the coupled dynamics of the system can be formulated in terms of an effective single-species process in the thermodynamic limit, and how persistent order parameters characterizing the stationary states may be computed from this process in agreement with existing replica studies of the statics. Numerical simulations confirm these results. The analysis of the dynamics allows an interpretation of two different types of phase transitions of the model in terms of memory onset at finite and diverging integrated response, respectively. We extend the analysis to the case of diluted couplings of an arbitrary symmetry, where replica theory is not applicable. Finally the dynamics and in particular the approach to the stationary state of the model with a finite number of traits is addressed.

description: Recently, a study has shown that the Bose Einstein Condensates formed by the $d^*$(2380) hexaquarks ($d^*$(2380)-BECs) can be thermally produced in the early universe and they are stable enough to be a competitive candidate of dark matter. Searching for the decaying signature of $d^*$(2380)-BECs is a possible way to verify this dark matter model. In this article, we discuss the scattering and decaying properties of the $d^*$(2380)-BECs and we show that the decay rate of the $d^*$(2380)-BECs is correlated with the TeV cosmic-ray flux. The predicted average decay rate in our Galaxy is several orders of magnitude larger than the current observed upper limit. Therefore, it would be very difficult for us to search for the decaying signature of the $d^*$(2380)-BEC dark matter model. Nevertheless, the size of the $d^*$(2380)-BECs may be large enough to have self-interaction so that we can possibly detect them in the future.

description: Quantum computation is an emerging technology that promises to be a powerful tool in many areas. Though some years likely still remain until significant quantum advantage is demonstrated, the development of the technology has led to a range of valuable resources. These include publicly available prototype quantum hardware, advanced simulators for small quantum programs and programming frameworks to test and develop quantum software. In this provocation paper we seek to demonstrate that these resources are sufficient to provide the first useful results in the field of procedural generation. This is done by introducing a proof-of-principle method: a quantum generalization of a blurring process, in which quantum interference is used to provide a unique effect. Through this we hope to show that further developments in the technology are not required before it becomes useful for procedural generation. Rather, fruitful experimentation with this new technology can begin now.

description: ASD (Abstract Stone Duality) is a re-axiomatisation of general topology in which the topology on a space is treated, not as an infinitary lattice, but as an exponential object of the same category as the original space, with an associated lambda-calculus. In this paper, this is shown to be equivalent to a notion of computable basis for locally compact sober spaces or locales, involving a family of open subspaces and accompanying family of compact ones. This generalises Smyth's effectively given domains and Jung's strong proximity lattices. Part of the data for a basis is the inclusion relation of compact subspaces within open ones, which is formulated in locale theory as the way-below relation on a continuous lattice. The finitary properties of this relation are characterised here, including the Wilker condition for the cover of a compact space by two open ones. The real line is used as a running example, being closely related to Scott's domain of intervals. ASD does not use the category of sets, but the full subcategory of overt discrete objects plays this role; it is an arithmetic universe (pretopos with lists). In particular, we use this subcategory to translate computable bases for classical spaces into objects in the ASD calculus.

description: Consumption of lowfat and skim milk has increased substantially over the past decade. This study investigates whether the change is due to price and expenditure effects or to a more fundamental preference change in milk demand. Parametric and nonparametric analytical approaches provide a comprehensive analysis of structural change in milk consumption in New York State. A nonparametric approach first finds evidence of structural change. A parametric likelihood-ratio test then confirms the existence of structural change using a Kalman filter specification. The value of this technical analysis of milk preferences is its implication for labeling initiatives. Milk fat labels have allowed consumers to act on a new set of preferences, thereby improving consumer welfare.
Quantum secure conditional direct communication via EPR pairs

Year: 2005

description: Two schemes for quantum secure conditional direct communication are proposed, where a set of EPR pairs of maximally entangled particles in Bell states, initially made by the supervisor Charlie, but shared by the sender Alice and the receiver Bob, functions as quantum information channels for faithful transmission. After insuring the security of the quantum channel and obtaining the permission of Charlie (i.e. Charlie is trustworthy and cooperative, which means the 'conditional' in the two schemes), Alice and Bob begin their private communication under the control of Charlie. In the first scheme, Alice transmits secret message to Bob in a deterministic manner with the help of Charlie by means of Alice's local unitary transformations, both Alice and Bob's local measurements, and both of Alice and Charlie's public classical communication. In the second scheme, the secure communication between Alice and Bob can be achieved via public classical communication of Charlie and Alice, and the local measurements of both Alice and Bob. The common feature of these protocols is that the communications between two communication parties Alice and Bob depend on the agreement of the third side Charlie. Moreover, transmitting one bit secret message, the sender Alice only needs to apply a local operation on her one qubit and send one bit classical information. We also show that the two schemes are completely secure if quantum channels are perfect.

Ultra-short-period Planets are Stable Against Tidal Inspiral

description: It has been unambiguously shown in both individual systems and at the population level that hot Jupiters experience tidal inspiral before the end of their host stars' main sequence lifetimes. Ultra-short-period (USP) planets have orbital periods $P < 1$ day, rocky compositions, and are expected to experience tidal decay on similar timescales to hot Jupiters if the efficiency of tidal dissipation inside their host stars parameterized as $Q_\ast'$ is independent of $P$ and/or secondary mass $M_{\mathrm{p}}$. Any difference between the two classes of systems would reveal that a constant $Q_\ast'$ model is insufficient. If USP planets experience tidal inspiral, then USP planet systems will be relatively young compared to similar stars without USP planets. Because it is a proxy for relative age, we calculate the Galactic velocity dispersions of USP planet candidate host and non-host stars using data from Gaia Data Release 2 supplemented with ground-based radial velocities. We find that main sequence USP planet candidate host stars have kinematics consistent with similar stars in the Kepler field without observed USP planets. This indicates that USP planet hosts have similar ages as field stars and that USP planets do not experience tidal inspiral during the main sequence lifetimes of their host stars. The survival of USP planets requires that $Q_\ast'\gtrsim10^7$ at $P\approx0.7$ day and $M_{\mathrm{p}}\approx2.6~M_{\oplus}$. This result demands that $Q_\ast'$ depend on the orbital period and/or mass of the secondary in the range $0.5\mathrm{~days}\lesssim P\lesssim5$ days and $1~M_{\oplus}\lesssim M_{\mathrm{p}}\lesssim1000~M_{\oplus}$.

description: Using farm data from three dairy-dependent communities in Wisconsin, this study addresses the question: Do small farms spend more locally than large farms? The work develops a theoretical model of farm cost functions with transaction costs varying between local and distant input sources. This model is then tested econometrically, describing farm costs and where they were spent as a function of transaction/search costs and farm characteristics. The results suggest that scale does matter to farm spending patterns.

description: The objective of this analysis was to identify the production practices used by farmers to change seasonal production. Production practices included milk production per cow, proportion of cows milking, number of first lactation animals entering the herd, number of cows leaving the herd, number of days to first breeding, and calves born. Farms that participated in a seasonal pricing plan during 1993, 1994, and 1995 decreased production practice seasonality in response to price premiums, which caused a decrease in production seasonality compared to nonparticipating farms. Participating farms showed a preference for adjusting entering first lactation animals and number of calves born, but did make adjustments in other practices as well.

Findings show that the distribution of wealth in 1996 was slightly more concentrated than in 1999, with the farm wealth component contributing significantly more toward measured concentration in both years than the nonfarm wealth component. The robustness of the findings under varied value judgments concerning society's level of aversion to wealth concentration is also examined.

description: This paper attempts to ascertain the requirements (in terms of ownership of factors of production) for successful adaptation to the Green Revolution in Indian agriculture. We estimate stochastic production frontiers for wheat in two Indian states: Haryana (which has been significantly affected by the Green Revolution) and Madhya Pradesh (where the Green Revolution has had much less effect). In Haryana, but not in Madhya Pradesh, larger farm size and ownership of land and machines positively influence technical efficiency. Thus, with the Green Revolution advancing, land consolidation and vesting of clear ownership rights of land and capital with farmers becomes important.

description: The Crab Nebula is used by many instruments as a calibration source, in particular at high energy, where it is one of the brightest celestial object. The spectrometer INTEGRAL SPI (20 keV - 8 MeV), in operation since October 2002, offers a large dataset dedicated to this source, with regular campaigns planned twice per year. We have analyzed the available data to quantify the source behavior on a long term scale and examine the stability level on timescales from hour to years. As a result, the source flux variability appears to be contained within less than +/- 5% around a ~ 20 yr mean value, for broad bands covering the 20 keV - 400 keV energy domain, above which statistic limits any firm conclusion. In term of spectral shape, the Band model provides a good description of the observed emission between 20 keV and 2.2 MeV. The averaged spectrum best fit parameters correspond to a low energy slope of 1.99 +/- 0.01, a high energy slope of -2.32 +/- 0.02 and a characteristic energy E c of 531 +/- 50 keV to describe the curvature joining both power laws. The spectral parameters have then been determined on the revolution timescale (~ 1 to 2 days) and their steadiness confirms the source emission stability. As a complementary result, this study demonstrates that the SPI instrument efficiency remains within 5% of its initial value, after 17 years of operation.

description: Given multiple input signals, how can we infer node importance in a knowledge graph (KG)? Node importance estimation is a crucial and challenging task that can benefit a lot of applications including recommendation, search, and query disambiguation. A key challenge towards this goal is how to effectively use input from different sources. On the one hand, a KG is a rich source of information, with multiple types of nodes and edges. On the other hand, there are external input signals, such as the number of votes or pageviews, which can directly tell us about the importance of entities in a KG. While several methods have been developed to tackle this problem, their use of these external signals has been limited as they are not designed to consider multiple signals simultaneously. In this paper, we develop an end-to-end model MultiImport, which infers latent node importance from multiple, potentially overlapping, input signals. MultiImport is a latent variable model that captures the relation between node importance and input signals, and effectively learns from multiple signals with potential conflicts. Also, MultiImport provides an effective estimator based on attentive graph neural networks. We ran experiments on real-world KGs to show that MultiImport handles several challenges involved with inferring node importance from multiple input signals, and consistently outperforms existing methods, achieving up to 23.7% higher NDCG@100 than the state-of-the-art method.

description: Assuming asymmetric information over farmer profits and zero transaction costs, prior literature has suggested that when regulating nonpoint source water pollution, a tax on management practices (inputs) can implement full-information allocations and is superior to a tax on estimated runoff. Using mechanism design theory under asymmetric information, this paper show that under the same assumptions, management practice taxes and taxes on estimated runoff are equally efficient.

description: The complete set of two-loop electroweak corrections to the decay width of the Higgs boson into two photons is presented. Two-loop contributions involving weak bosons and the top quark are computed in terms of an expansion in the Higgs external momentum. Adding these results to the previously known light fermion contributions, we find that the total electroweak corrections for a Higgs boson with 100 GeV

description: A discrete choice model and site-specific data are used to analyze land use choices between crop production and pasture in the Corn Belt. The results show that conversion probabilities depend on relative returns, land quality, and government policy. In general it is found that landowners are less inclined to remove land from crop production than to convert land to crop production.
A remark on periods of periodic sequences modulo $m$

description: Let $\{G_n\}$ be a periodic sequence of integers modulo $m$ and let $\{SG_n\}$ be the partial sum sequence defined by $SG_n:= \sum_{k=0}^nG_k $ (mod $m$). We give a formula for the period of $\{SG_n\}$. We also show that for a generalized Fibonacci sequence $F(a,b)_n$ such that $F(a,b)_0=a$ and $F(a,b)_1=b$, we have $$S^i F(a,b)_n = S^{i-1}F(a,b)_{n+2}-{n+i \choose i-2}a-{n+i \choose i-1} b$$ where $S^i F(a,b)_n $ is the i-th partial sum sequence successively defined by $S^i F(a,b)_n := \sum_{k=0}^n S^{i-1}F(a,b)_k$. This is a generalized version of the well-known formula $$\sum_{k=0}^n F_k = F_{n+2} -1$$ of the Fibonacci sequence $F_n$.

Multiplexing Guided Optical and Acoustic Waves for Efficient Acousto-Optic Devices

description: Acousto-optic devices utilize the overlap of acoustic and optical fields to facilitate photon-phonon interactions. For tightly confined optical and acoustic fields, such as the sub-wavelength scales achievable in integrated devices, this interaction is enhanced. Broadband operation which fully benefits from this enhancement requires light and sound to co-propagate in the same cross-section, a geometry currently lacking in the field. We introduce the `acoustic-optical multiplexer', which enables this co-linear geometry, and demonstrate through simulations a proof-of-concept design. Using suspended silicon and silica beams, the multiplexer combines two optical modes and an acoustic mode into a single, co-guided output port with low insertion loss and reflection for both optics and acoustics. The first design in its class, the multiplexer enables integrated acousto-optic devices to achieve efficient photon-phonon interactions.

Superheating fields of semi-infinite superconductors and layered superconductors in the diffusive limit: structural optimization based on the microscopic theory

description: We investigate the superheating fields $H_{sh}$ of semi-infinite superconductors and layered superconductors in the diffusive limit by using the well-established quasiclassical Green's function formalism of the BCS theory. The coupled Maxwell-Usadel equations are self-consistently solved to obtain the spatial distributions of the magnetic field, screening current density, penetration depth, and pair potential. We find the superheating field of a semi-infinite superconductor in the diffusive limit is given by $H_{sh} = 0.795 H_{c0}$ at the temperature $T \to 0$. Here $H_{c0}$ is the thermodynamic critical-field at the zero temperature. Also, we evaluate $H_{sh}$ of layered superconductors in the diffusive limit as functions of the layer thicknesses ($d$) and identify the optimum thickness that maximizes $H_{sh}$ for various materials combinations. Qualitative interpretation of $H_{sh}(d)$ based on the London approximation is also discussed. The results of this work can be used to improve the performance of superconducting rf resonant cavities for particle accelerators.

The Exact Solution of the Asymmetric Exclusion Problem With Particles of Arbitrary Size: Matrix Product Ansatz

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The exact solution of the asymmetric exclusion problem and several of its generalizations is obtained by a matrix product {\it ansatz}. Due to the similarity of the master equation and the Schrödinger equation at imaginary times the solution of these problems reduces to the diagonalization of a one dimensional quantum Hamiltonian. We present initially the solution of the problem when an arbitrary mixture of molecules, each of then having an arbitrary size ($s=0,1,2, ...$) in units of lattice spacing, diffuses asymmetrically on the lattice. The solution of the more general problem where we have | the diffusion of particles belonging to $N$ distinct class of particles ($c=1, ..., N$), with hierarchical order, and arbitrary sizes is also solved. Our matrix product {\it ansatz} asserts that the amplitudes of an arbitrary eigenfunction of the associated quantum Hamiltonian can be expressed by a product of matrices. The algebraic properties of the matrices defining the {\it ansatz} depend on the particular associated Hamiltonian. The absence of contradictions in the algebraic relations defining the algebra ensures the exact integrability of the model. In the case of particles distributed in $N>2$ classes, the associativity of the above algebra implies the Yang-Baxter relations of the exact integrable model.

subject: willingness to pay

description: This paper aims at assessing: 1) consumers' habits concerning beef consumption and their responses to the BSE both immediately and at a longer term; 2) consumers' attitudes and willingness to pay for organic beef, an obvious alternative to regular beef in terms of safety. It is based on two random telephone surveys, the first one conducted in 2001 (few months after the BSE crisis) and the second one in 2003. The analysis shows that though the effect of the BSE crisis has weakened along with time distance, it left some permanent signs in consumers' behaviour. The analysis of the effect of the time distance from the BSE crisis on consumers' attitudes towards organic beef leads to the main conclusion that the demand for organic beef reduced, but that in the meantime it became more inelastic.
Structure/function and mode of action of antimicrobial
Creators: name: Fong, Carol L. Friedrich
Publisher: name: University of British Columbia
Year: 2011

description: Antimicrobial cationic peptides are ubiquitous in nature and are thought to be a component of the first line of defense against infectious agents. It is important to study these peptides in order to use them as potential templates for new antibiotic therapeutics. The aim of this study was to determine the structure/activity relationships of selected peptides and to determine the mode of action of these peptides on Gram positive bacteria. Studies with model membrane systems using circular dichroism and fluorescence spectroscopy indicated that these active peptides were induced into a more defined structure upon binding to lipids and detergents. In general, peptide interaction with lipids and detergents were similar. The peptides entered a hydrophobic environment, with tryptophan residues inaccessible to the aqueous solution. Although there were differences between peptides in specific interactions, no correlation could be made between lipid interaction and antimicrobial specificity or activity. The activity of cationic peptides from different structural classes was determined on various Gram positive strains and the killing kinetics of these peptides were very similar at 10-fold the MIC. Electron microscopy of S. aureus and S. epidermidis treated with the peptides at 10-fold the MIC showed variability in effects on bacterial structure. Mesosome-like structures were seen to develop in S. aureus with all peptides, whereas different effects, including nuclear condensation, were seen in the case of S. epidermidis. The membrane-potential-sensitive fluorophore DiSC₃(5) was utilized to assess the interaction of antimicrobial peptides with the cytoplasmic membrane of S. aureus. Studies of the kinetics of killing and membrane depolarization showed that no correlation could be made between cytoplasmic membrane depolarization and peptide activity. Thus, although cytoplasmic membrane permeabilization was a widespread ability among peptides, it did not appear to be the killing mechanism. Macromolecular synthesis assays showed that all peptides studied had intracellular effects, and these were often seen at sub-lethal peptide concentrations. The peptides differed in their specific effects on macromolecular synthesis. In general, evidence presented here suggested that cytoplasmic membrane disruption is not the sole mechanism of action against bacteria, and that multiple targets may be involved. The specific mechanism differs between peptides of different structural classes
How to Derive Market Impacts of the Luxembourg Agreement on the German Beef Market - A Synthetic Uniform Model versus an Econometric Country Specific Model

description: The paper discusses two partial equilibrium models, one is a synthetic model (GAPsi) and the other an econometrically estimated model (AG-MEMOD). While the synthetic model incorporates only price impacts and some shifts, the econometric model also reflects other influencing factors. Price formation includes policy measures as price wedges, or as explaining variables in key price equations or price transmission equations, which is also true when premiums and decoupling are regarded. When the Luxembourg Agreement is simulated, our example of beef shows that these model differences induce deviations in model results, especially concerning prices and trade.
