description: The Dicke model and Rabi model can undergo phase transitions from the normal phase to the superradiant phase at the same boundary, which can be accurately determined using some approximated approaches. The underlying mechanism for this coincidence is still unclear and the universality class of these two models is elusive. Here we prove this phase transition exactly using the path-integral approach based on the faithful Schwinger fermion representation, and give a unified phase boundary condition for these models. We demonstrate that at the phase boundary, the fluctuation of the bosonic field is vanished, thus it can be treated as a classical field, based on which a much simplified method to determine the phase boundary is developed. This explains why the approximated theories by treating the operators as classical variables can yield the exact boundary. We use this method to study several similar spin and boson models, showing its much wider applicability than the previously used approaches. Our results demonstrate that these phase transitions belong to the same universality by the classical Landau theory of phase transitions, which can be confirmed using the platforms in the recent experiments.

description: This piece of work is an evaluation on the performance of a farm credit Cooperative in the state of Minas Gerais with 12 service agencies in different cities. For such purpose the Modelo de Gestão Econômica ( Economic Management Model )-GECON was used, which is a tool for managerial analysis developed by the GECON Nucleus researchers staff, supported by the FIPECAFI foundation of the University of São Paulo. The GECON is a model which can be applied on several types of organizations and has been broadly used on banking organizations. Through analysis it was verified that the cooperative analysed has a structure of relatively high costs and expenses, which compromises its economic results and makes it necessary to promote an effective reduction/rationalization in its expenditures, as well as to seek to exploiting the potentialities available in such area of operation.

description: This article analyzes the impacts of the changes motivated by the opening process of the Brazilian economy in the composition of manpower and in the demand of workers' training with technical formation at the high school level in three agroindustrial companies of Minas Gerais State. It was used the method of historic-organizational case study to collect data and conduct a comparative analysis accomplishing the period from 1990 to 1998. It was observed that the researched companies passed for processes of technological and administrative restructuring, investing in installations, equipment, release of new products, as well as sticking to new methods and administrative practices, of production and marketing. As a result of that restructuring, they also started to invest in training and they tend to demand labor with minimal schooling at high school level or with technical course of the same level. However, the interviewees evaluate that the offered technical courses were not up-date and did not assist appropriately to marketing demands. They suggest that were included in the curricula disciplines which approach human relationships and that the schools come to have larger exchange with the companies through technical visits and apprenticeships, which would allow better relationship between theory and practice.
Home economics education in British Columbia 1913-1936 : through postcolonial eyes
Creators: name: De Zwart, Mary Leah
Publisher: name: University of British Columbia
Year: 2009

description: My study examines white cultural practices in home economics education in British Columbia between 1913 and 1936 through two home economics manuals developed in the province for the express purpose of educating young women. My methodology is informed by postcolonial constructs, social feminism, and white studies. My experiences as a classroom teacher and as a volunteer teacher in Malawi are interwoven with my findings. I use the metaphor of white sauce, a recipe frequently made in traditional classrooms, in describing the current close alignment of home economics with white culture. To see home economics through postcolonial eyes means to examine the aftermath of practices that developed from colonial times. While the argument has been made that Canada is not postcolonial, for the purposes of my discussion, I consider it to be a settler colony. I examine three fundamental aspects of postcolonial analysis, gender, class, and race from the perspective that home economics is a gendered subject dominated by white cultural practices and practical rather than academic in focus. In conclusion I argue that no grand narrative is available for re-imagining home economics as a vital force in education. The voices of young professionals and examples of atypical home economics teachers demonstrate that change in home economics is possible. The recognition that home economics education of the past has reflected white cultural values will allow a re-envisioning of a more ethical, meaningful and responsive home economics education of the future. Other curriculum areas can also benefit from re-examining the roots of their practice.

description: Descartes’ thought in the 17th century announces the dawning of Modern Age. One of his heritages was the notion that we could get to know further about nature, reducing the complex to its simplest parts. This form of thinking has made us see reality as one made up of parts. The explanation of such parts would enable us to number, ordenate and understand the all. The stratification and hierarchyzation of what one calls society in parts, similar to an organism or as a system formed by economy, communication, language, religion, politics, State, rights, has fomented the idea that such spheres find themselves separated, whereas they are not in fact. This article means to develop the idea that social reality, when seen as a whole, may be able to gather together previously stagnant spheres by means of a totality. In this sense, this work intends to relate the productive practices under the aegis of capitalism as also being a communication phenomenon. For such, one analises how production of goods in different production and accumulation capitalist models and their labor handling ways in the models known as “taylorist-fordist” and “japanese” relate themselves as different and inequal communicational and informational practices, both in the internal and external ranges of the companies or of the productive chain they belong to.

description: We present the first calculation of gravitational wave emission produced in the gravitational collapse of uniformly rotating neutron stars to black holes in fully three-dimensional simulations. The initial stellar models are relativistic polytropes which are dynamically unstable and with angular velocities ranging from slow rotation to the mass-shedding limit. An essential aspect of these simulations is the use of progressive mesh-refinement techniques which allow to move the outer boundaries of the computational domain to regions where gravitational radiation attains its asymptotic form. The waveforms have been extracted using a gauge-invariant approach in which the numerical spacetime is matched with the non-spherical perturbations of a Schwarzschild spacetime. Overall, the results indicate that the waveforms have features related to the properties of the initial stellar models (in terms of their w-mode oscillations) and of the newly produced rotating black holes (in terms of their quasi-normal modes). While our waveforms are in good qualitative agreement with those computed by Stark and Piran in two-dimensional simulations, our amplitudes are about one order of magnitude smaller and this difference is mostly likely due to our less severe pressure reduction. For a neutron star rotating uniformly near mass-shedding and collapsing at 10 kpc, the signal-to-noise ratio computed uniquely from the burst is S/N ~ 0.25, but this grows to be S/N

description: The AGMEMOD Partnership seeks to capture the inherent heterogeneity of the agricultural systems existing by combining individual country models of 27 EU Member States and several accession countries into one single model while still maintaining analytical consistency. Although this approach facilitates the comparison of the impact of a policy across different Member States, it generates challenges in practical implementation, ranging from high communication and administration requirements to aggregation and consistency issues. This contribution provides insights into the different challenges posed to the scientists and discusses the key issues for maintenance and further development of such a complex system. Specific attention is paid to technical devices and tools as well as to the design of institutional settings for avoiding inconsistencies.

description: CO2 reichert in sich der Atmosphäre an. Daher ist die Summe an CO2-Emissionen entscheidend für die Einhaltung bestimmter Grenzen der Erderwärmung. Auf dieser naturwissenschaftlichen Grundlage fordern z. B. „Fridays for Future“, dass sich nationale Emissionspfade an einem verbleibenden globalen CO2-Budget orientieren sollen. Bei der Umsetzung stellen sich jedoch folgende Fragen: An welchem konkreten global verbleibenden CO2-Budget sollen sich die Staaten bei ihren NDCs orientieren? An welcher Aufteilung eines globalen CO2-Budgets sollen sich Staaten bei ihren NDCs orientieren? Wie kann ein daraus resultierendes nationales CO2-Budget in einen sinnvollen nationalen Emissionspfad übersetzt werden? Das hier präsentierte Extended Smooth Pathway Model (ESPM) bietet einen Rahmen, um diese Fragen beantworten zu können. Wenn die Vertragsstaaten bei ihren NDCs ein dahinterstehendes globales CO2-Budget und einen dahinterstehenden Verteilungsschlüssel transparent machen, kann dies einen Diskurs in Gang setzen, der zu konvergierenden globalen Orientierungsgrößen führt und damit zu in Summe Paris-kompatiblen NDCs beiträgt.

description: In order to clarify the properties of the secondary clump star HD 226808 (KIC 5307747), we combined four years of data from Kepler space photometry with high-resolution spectroscopy of the High Efficiency and Resolution Mercator Échelle Spectrograph mounted on the Mercator telescope. The fundamental atmospheric parameters, radial velocities, rotation velocities, and elemental abundance for Fe and Li were determined by analyzing line strengths and fitting-line profiles, based on a 1D local thermodynamic equilibrium model atmosphere. Second, we analyzed a photometric light curve obtained by Kepler and we extracted asteroseismic data of this target using Lets Analysis, Use and Report of Asteroseismology, a new seismic tool developed for the study of evolved FGK solar-like stars. We determined the evolutionary status and effective temperature, surface gravity, metallicity, microturbulence, and chemical abundances for Li, Ti, Fe, and Ni for HD~226808, by employing spectroscopy, asteroseismic scaling relations, and evolutionary structure models built in order to match observed data. Our results also show that an accurate synergy between good spectroscopic analysis and asteroseismology can provide a jump toward understanding evolved stars.}

description: The paper provides an analysis of the impacts of the biofuel policy on the French arable crop sub-sector. The model used is a biofuel supply model composed of an agricultural module and an industrial biofuel processing module. The agricultural supply model is an aggregation of 1094 farm models, based on data from the French Farm Accountancy Data Network (FADN). Different biofuel chains are included in the model: ethanol from wheat and sugar beet, biodiesel (Vegetable Oil Methyl Ester) from rapeseed and sunflower. Scenarios are built upon the recent policy of an increased demand of biofuels for the next years, under the assumption of fulfilling the targets with domestic production only. Results show that the incorporation target of 7% of biofuels in transport fuels would have small impacts on the wheat and sugar beet cultivated areas but would lead to a considerable increase in the rapeseed area. In the main producing regions, the rapeseed area would reach approximatively a third of the total farmed area. This would not be without consequences on the environment, due to the increase in pesticide use that this change in cropping patterns would most certainly induce. It would not be possible to reach a 10% incorporation target without imports. Furthermore, we analyse the impacts of reaching these production levels on the rapeseed opportunity costs, and show that reaching high level of incorporation (above 7%) will need a very high increase in rapeseed prices paid to farmers. We calculate the impacts of this opportunity cost increase on the competitiveness of biofuels with respect to fossil oil, for different levels of oil prices. We test the sensitivity of the results against the wheat price, and show that this latter will have a significant impact on the biodiesel competitiveness.

description: We present a continuous time model of maturation and survival, obtained as the limit of a compartmental evolution model when the number of compartments tends to infinity. We establish in particular an explicit formula for the law of the system output under inhomogeneous killing and when the input follows a time-inhomogeneous Poisson process. This approach allows the discussion of identifiability issues which are of difficult access for finite compartmental models. The article ends up with an example of application for anticancer drug pharmacokinetics/pharmacodynamics.

description: Research on consumer’s use of food labels have been heavily increasing in the last 20 years from some pioneering works in the eighties. Different analytical approaches to the subject may be identified in the scientific literature, among them, the analysis of the use of different types of information often labeled in food markets, and its relationship with some consumer characteristics. The paper fall into the scope of this type of approach. From a survey to 1500 Spanish consumers, stratified by regions (zone) and type of habitat (rural, urban and metropolitan), a composite index, made by aggregating reading frequencies of nine different types of information (calories, ingredients, expiry date, nutritional composition, etc.) has been calculated, and both an OLS and a ordered multinomial Probit models have been estimated trying to find out the relationship between the intensity of using food labels and some characteristics and features of consumers. From this analysis some conclusions have, finally, been drawn.

description: We report on observations aimed at searching for flux variations from the proposed IR counterpart of the Anomalous X-ray Pulsar XTE J1810-197. These data, obtained in March 2004 with the adaptive optics camera NAOS-CONICA at the ESO VLT, show that the candidate proposed by Israel et al. (2004) was fainter by Delta H=0.7+/-0.2 and Delta Ks=0.5+/-0.1 with respect to October 2003, confirming it as the IR counterpart of XTE J1810-197. We also report on an XMM-Newton observation carried out the day before the VLT observations. The 0.5-10 keV absorbed flux of the source was 2.2x10^-11 erg/s/cm^2, which is less by a factor of about two compared to the previous XMM-Newton observation on September 2003. Therefore, we conclude that a similar flux decrease took place in the X-ray and IR bands. We briefly discuss these results in the framework of the proposed mechanism(s) responsible for the IR variable emission of Anomalous X-ray Pulsars.

description: We investigate many-body spin squeezing dynamics in an XXZ model with interactions that fall off with distance $r$ as $1/r^α$ in $D=2$ and $3$ spatial dimensions. In stark contrast to the Ising model, we find a broad parameter regime where spin squeezing comparable to the infinite-range $α=0$ limit is achievable even when interactions are short-ranged, $α>D$. A region of "collective" behavior in which optimal squeezing grows with system size extends all the way to the $α\to\infty$ limit of nearest-neighbor interactions. Our predictions, made using the discrete truncated Wigner approximation (DTWA), are testable in a variety of experimental cold atomic, molecular, and optical platforms.

description: Polydimethylsiloxane (PDMS) microfluidic devices have become a standard tool for engineering cells and multicellular networks in vitro. However, the reservoirs, or through-holes where cells access the devices, are usually fabricated manually using a biopsy punch, making it difficult to create a large-scale array of small (<1 mm) reservoirs. Here, we present a fabrication process for a thin-film microfluidic device, or a microfluidic film (μFF), containing an array of through-holes. Holes as small as 100 μm by 100 μm spanning 10 mm by 10 mm are characterized. The geometry of the through-holes was precisely defined by the photoresist mould. A challenge in using the μFF for cell culture was air-bubble entrapments in the through-holes, which became more prominent with smaller holes. We show that this issue can be overcome using ethanol-mediated wetting of the PDMS surface, and demonstrate functional recording of cultured neuronal networks grown in μFFs. This technology opens new application of microfluidic devices to mesoscale systems comprised of several tens to hundreds of cells.

Calculating the gauge-invariant two-point correlation function of gluonic field strengths

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The two-point gauge-invariant correlation function of gluonic field strengths, which is the main input in the stochastic vacuum model, is derived by using its relation to the Green functions of one- and two-gluon gluelumps. These Green functions are found by evaluating the path integrals of one and two gluons confined in the field of an infinitely heavy adjoint source. This allows one to obtain also the terms in the exponential asymptotics of the two-point correlation function, which are produced by fluctuations of the gluons around their mean separation from the source. The pre-exponents are derived as well, demonstrating some novel dependences on the distance.

description: This paper provides a consumer-driven definition of traditional food products (TFP) and investigates the image European consumers have about this food product category. Data were collected from representative consumer samples in six European countries, including Belgium, France, Italy, Norway, Poland and Spain, with a total sample size of 4,828 participants. European consumers define traditional foods as well-know products, products that one can eat very frequently, and products that were already eaten by grandparents. Although positive, association of TFP with naturalness and low processing is less pronounced. Sensory, health- and environment-related attribute perceptions contribute positively to the image of TFP, whereas perceived convenience, price, and availability contribute negatively to the TFP image. Finally, TFP are mainly pictured as foods that agree well with people who love national or regional cuisine, with people living in the countryside, equally so with men and women, though more so with families with children rather than singles or household without children. The empirical findings provide insights with particular relevance for TFP positioning, marketing communications around TFP and further development of the TFP market in Europe.

description: We have constructed self-consistent light and mass distribution models for four disk galaxies at redshifts z = 0.48, 0.58, 0.81 and 0.88, using the HST archive WFPC2 observations and rotation curves measured by Vogt et al. (1996) and Rigopoulou et al. (2002). The models consist of three components: a bulge, a disk and a dark matter halo. Similarly to the sample studied in Paper I (Tamm & Tenjes, 2003), light distribution of the galaxies in the outer parts is clearly steeper than a simple exponential disk. After applying k-corrections, calculated mass-to-light ratios for galactic disks within the maximum disk assumption are M/L_B = 0.9, 7.4, 4.3 and 1.4, respectively. Together with the galaxies from Paper I, the mean = 2.5 at ~0.9, indicating no significant evolution of M/L_B with redshift. Central densities of dark matter halos for an isothermal model are 0.008, 0.035, 0.013, and 0.022 in units M_sun/pc^3, respectively. Together with the galaxies from Paper I, the DM central density of the four galaxies at mean readshift ~0.9 is rho(0) = (0.012-0.028) M_sun/pc^3, also showing no significant evolution with redshift.

description: Among consumers there is an increasing interest and concern about the ways food is produced. This calls for the poultry industry to differentiate their products and production methods to directions valued by the consumers. In this study we use choice experiment to analyse the importance of broiler production method and the country of origin for the Finnish consumers. In the experiment, we offer several alternatives for regular broiler, including products that have been produced using organic methods, as well as products produced by emphasising animal welfare or consumer health aspects. The conditional logit model of consumer preferences for broiler meat in Finland revealed the very strong positive perceptions of domestically produced broiler products. Although the effect of production method was minor it also had an impact on consumer choice behaviour, particularly emphasising animal welfare in production increased the choice probability. The latent class analysis revealed the heterogeneity of consumer preferences but did not facilitate profiling the consumer groups based on socioeconomic data.

description: One of the challenges in quantum computing is the synthesis of unitary operators into quantum circuits with polylogarithmic gate complexity. Exact synthesis of generic unitaries requires an exponential number of gates in general. We propose a novel approximate quantum circuit synthesis technique by relaxing the unitary constraints and interchanging them for ancilla qubits via block-encodings. This approach combines smaller block-encodings, which are easier to synthesize, into quantum circuits for larger operators. Due to the use of block-encodings, our technique is not limited to unitary operators and can also be applied for the synthesis of arbitrary operators. We show that operators which can be approximated by a canonical polyadic expression with a polylogarithmic number of terms can be synthesized with polylogarithmic gate complexity with respect to the matrix dimension.

description: Bread contains a wide range of important nutritional components which provide a positive effect on human health. However, the consumption of bread in Belgium is declining during the last decades. This is due to factors such as changing eating patterns and a increasing choice of substitutes like breakfast cereals and fast foods. The aim of this study is to investigate consumer’s quality perception of bread towards sensory, health and nutrition attributes. Consumer’s quality perception of bread seams to be determined by sensory and health attributes. Three clusters of consumers are identified based on these attributes. In the first cluster, consumers’ quality perception of bread is not dependent on the health attributes it embraces, but to some extent on sensory attributes. For the second cluster, both health and sensory attributes appear to influence quality perception. In the third cluster only sensory attributes appear to be important in determining quality perception, though in a negative direction. The results of this study will possibly help health professionals and policy makers to systematically inform the consumers about the positive effects of bread and its components. Furthermore, firms can use the result to build up a tailor-made marketing strategy.

description: Crystal and electronic structure, lattice dynamics and thermodynamic stability of little known mixed valent diamagnetic AgIAgIIIF4 beta form of AgF2 is thoroughly examined for the first time and compared with well known antiferromagnetic AgIIF2 alpha form within the framework of Density Functional Theory based methods, phonon direct method and quasiharmonic approximation. Computed equations of state, bulk moduli, electronic densities of states, electronic and phonon band structures including analysis of optically active modes and p T phase diagram of the alpha/beta system are presented. This study demonstrates that alpha is thermodynamically preferred over beta at all temperatures and pressures of its existance but simultaneously beta is dynamically stable in much broader pressure range. The beta phase is discussed in broader context of isostructural ternary metal fluorides and isolectronic oxides including NaCuO2, the reference compound for existence of CuIII species in high temperature oxocuprate superconductors.

description: A fixed-effects panel data demand model for five New York State markets is estimated to determine the differential impacts of generic fluid milk advertising by media type. Empirical results indicate that among the four media outlets, television advertising has the largest impact on per capita demand, followed by radio, outdoor, and print. Based on the estimated media-specific elasticities, media reallocation of advertising expenditures suggests that milk sales could increase significantly. The results indicate that cooperative media plan strategies developed between the New York regional advertising program and the national advertising programs would achieve the greatest benefits.

description: Predicted masses of J^P=0^+ and 1^+ states of D_{sJ} and D by a potential model proposed some time ago by two of us (T.M. and T.M.), in which the Hamiltonian and wave functions are expanded in 1/m_Q with m_Q heavy quark mass respecting heavy quark symmetry, have recently been confirmed by BaBar and Belle experiments within one percent accuracy. In this Letter, decay modes of 0^+ and 1^+ states of B and B_s mesons are discussed using the predicted masses of this model.

description: This paper presents the methodology, assumptions, and data used to generate regional and national environmental benefit estimates of the USDA’s Conservation Reserve Program (CRP). It’s assumed that, without the program, production and conservation practices on CRP lands would be the same as those used on surrounding lands. When range and forest lands are (are not) included as land-use options, 54 (71) percent of the CRP land would be in crop production—which is consistent with past analyses. Soil erosion would be 222 to 248 million tons per year—about 11 percent—higher than the current level. Benefits are estimated by applying environmental benefit models, estimated in previous analyses, to the CRP’s estimated effect on erosion and wildlife habitat. Nationally, the CRP is estimated to provide $1.3 billion in annual benefits, which represents 75 to 80 percent of the program’s cost. In seven of the 10 USDA Farm Production Regions, the CRP’s environmental benefits exceed costs. Thus, reallocating acreage to these regions could increase net program benefits. However, because many benefits could not be estimated, one cannot conclude that regional and national benefits do not exceed costs.

description: We theoretically study the tunnel magnetoresistance (TMR) effect in (111)-oriented junctions Co/MgO/Co(111) and Ni/MgO/Ni(111). The Co-based junction is shown to have a TMR ratio over 2000$\%$, which is one order higher than that of the Ni-based one. The high TMR ratio is attributed to the interfacial resonance effect: The interfacial $d$-$p$ antibonding states are formed close to the Fermi level in the majority-spin channel and these states in both interfaces resonate with each other. This differs essentially from the conventional coherent tunneling mechanism of high TMR ratios in Fe(Co)/MgO/Fe(Co)(001).

Parochodaeus bituberculatus

description: Parochodaeus bituberculatus (Erichson, 1847) (Fig. 1)
 Diagnosis. This species can be distinguished from other Chilean scarabaeoids by the absence of a true ocular canthus dividing the eye, and for having the clypeus shorter and frons armed with two elongate and obsoletes tubercles (Fig. 1B). The protibial apex is straighter and narrower (Fig. 1C). Ochodaeidae possess pectinate mesotibial spurs not found in other scarabaeoids in the region (Fig. 1D). The elytral locking mechanism consists of acute elytral apices and bituberculate propygidium.
 Specimens examined. 1 female at: Chile, Arica y Parinacota, Zapahuira, pista de aterrizaje, 18°18’57.12’’S – 69°36’22.51’’W, 3368 m, light trap, 29-III-2013, col. A. Fierro (JMEC). 1 male at: Chile, Arica y Parinacota, Pachama, 18°25’41,15’’S, 69°31’34,07’’W, 3443 m, light trap, 29-III-2013, col. A. Fierro (MNNC).
 Distribution. The native range of P. bituberculatus includes west side of Peru (Erichson 1847; Ratcliffe et al. 2015). New country record: Chile, Arica and Parinacota Region, Parinacota Province (Fig. 3).
 Habitat. Parochodaeus bituberculatus was found in the mountains located east of the city of Arica in northern Chile, between 3,368–3,443 m. The native vegetation of this locality consists principally of resinous shrubs, herbaceous plants, cacti, and coarse grasses. The distribution corresponds to the Puna biogeographic province that also extends into eastern Bolivia, southern Peru, northern Argentina, and Chile (Morrone 2001).
 Remarks. Erichson (1847) described the species, but the only information given is that the specimen was from the west side of the Andes in Peru. The only recent specimens known are in the J.-B. Huchet collection in Paris, and are from Chaute, Peru at an elevation of 2,400 m (M.J. Paulsen, University of Nebraska State Museum, Lincoln, Nebraska, United States of America, personal communication).

Orderly Marketing in Agriculture Revisited

subject: market orders

description: This paper presents a model of economic behavior that explicates the phenomenon known as “orderly marketing,” which was a main objective of the Marketing Orders agricultural program introduced early in the New Deal. Recent analyses of marketing orders start with an implicit assumption that there is no market failure—thus, that price regulation can cause only deviations from the first-best market solution. However, historical evidence suggests that disorderly marketing might refer to a kind of market imperfection. In the model presented here, a monopsonist processor sets a price to be paid, and an aggregate quantity to be purchased. In some states of the world, some farmers are excluded from the market. In other words, nonprice rationing can occur, and changes in consumer expenditure for the final product are absorbed by the processor rather than passed along to the farmer. The classified price and pooling provisions of federal orders can lead to a Pareto improvement in welfare.

description: We discuss structural aspects of the functional renormalisation group. Flows for a general class of correlation functions are derived, and it is shown how symmetry relations of the underlying theory are lifted to the regularised theory. A simple equation for the flow of these relations is provided. The setting includes general flows in the presence of composite operators and their relation to standard flows, an important example being NPI quantities. We discuss optimisation and derive a functional optimisation criterion. Applications deal with the interrelation between functional flows and the quantum equations of motion, general Dyson-Schwinger equations. We discuss the combined use of these functional equations as well as outlining the construction of practical renormalisation schemes, also valid in the presence of composite operators. Furthermore, the formalism is used to derive various representations of modified symmetry relations in gauge theories, as well as to discuss gauge-invariant flows. We close with the construction and analysis of truncation schemes in view of practical optimisation.

description: As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices, and frozen imports became more responsive. Unconditional own-price elasticities also show that, over time, imports of chilled lamb became less responsive to import prices while frozen imports became more responsive to import prices.

description: We discuss theoretically a setup where a time-dependent current consisting of a DC bias and two sinusoidal harmonics is driven through a sample. If the sample exhibits current-dependent shot noise, the down-converted noise power spectrum varies depending on the local-oscillator phase of the mixer. The theory of this phase-dependent noise is applied to discuss the measurement of the radio-frequency single-electron transistor. We also show that this effect can be used to measure the shot noise accurately even in nonlinear high-impedance samples.
